**CAUTIONARY STATEMENT ABOUT FORWARD-LOOKING STATEMENTS**

This annual report contains forward-looking statements. All statements, other than statements of present or historical fact included in or incorporated by reference in this annual report, regarding future financial performance of QT Imaging Holdings, Inc (the "Company," "we," "our," "us" or "QT Imaging"), as well as the Company's strategy, future operations, financial position, estimated revenues, and losses, projected costs, prospects, plans and objectives of management are forward-looking statements. When used in this annual report, the words "anticipate," "believe," "continue," "could," "estimate," "expect," "intends," "may," "might," "plan," "possible," "potential," "predict," "project," "should," "will," "would" the negative of such terms and other similar expressions are intended to identify forward-looking statements, although not all forward-looking statements contain such identifying words. These forward-looking statements are based on management's current expectations, assumptions, hopes, beliefs, intentions and strategies regarding future events and are based on currently available information as to the outcome and timing of future events. The Company cautions you that these forward-looking statements are subject to all of the risks and uncertainties, most of which are difficult to predict and many of which are beyond the control of the Company, incident to its business.

These forward-looking statements are based on information available as of the date of this annual report, and current expectations, forecasts and assumptions, and involve a number of risks and uncertainties. Accordingly, forward-looking statements in this annual report and in any document incorporated herein by reference should not be relied upon as representing the Company's views as of any subsequent date, and the Company does not undertake any obligation to update forward-looking statements to reflect events or circumstances after the date they were made, whether as a result of new information, future events or otherwise, except as may be required under applicable securities laws.

As a result of a number of known and unknown risks and uncertainties, the Company's actual results or performance may be materially different from those expressed or implied by these forward-looking statements. Some factors that could cause actual results to differ include:

• changes in applicable laws or regulations;

• the outcome of any legal proceedings against the Company;

• the financial and business performance of the Company, including financial projections and business metrics and any underlying assumptions thereunder;

• the Company's ability to successfully and timely develop, sell and expand its technology and products, and otherwise implement its growth strategy;

• risks relating to the Company's operations and business, including information technology and cybersecurity risks, loss of customers and deterioration in relationships between the Company and its employees;

• risks related to increased competition;

• risks that the Company experiences as difficulties in managing its growth and expanding operations;

• the impact of geopolitical, macroeconomic and market conditions;

• the ability to successfully select, execute or integrate future acquisitions into the business; and

• other risks and uncertainties set forth in this annual report in the section entitled "*Risk Factors*" beginning on page 34.

Because forward-looking statements are inherently subject to risks and uncertainties, some of which cannot be predicted or quantified and some of which are beyond our control, you should not rely on these forward-looking statements as predictions of future events. The events and circumstances reflected in our forward-looking statements may not be achieved or occur, and actual results could differ materially from those projected in the forward-looking statements. Moreover, we operate in an evolving environment. Some of these risks and uncertainties may in the future be amplified by events we do not expect or cannot predict. Additionally, new risk factors and uncertainties may emerge from time to time, and it is not possible for management to predict all risk factors and uncertainties. As a result of these factors, the forward-looking statements in this annual report may not prove to be accurate.

ii

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

Except as required by applicable law, we do not plan to publicly update or revise any forward-looking statements contained in this annual report, whether as a result of any new information, future events, changed circumstances or otherwise. You should read this annual report completely, and with the understanding that our actual future results may be materially different from what we expect. We qualify all of our forward-looking statements by these cautionary statements.

**SUMMARY OF RISK FACTORS**

The below summary of risk factors provides an overview of many of the risks we are exposed to in the normal course of our business activities. As a result, the below summary risks do not contain all of the information that may be important to you, and you should read the summary risks together with the more detailed and complete discussion of risks set forth under the heading "*Risk Factors*" in Part I, Item 1A of this annual report, as well as elsewhere in this annual report. Additional risks, beyond those summarized below or discussed elsewhere in this annual report, may apply to our activities or operations as currently conducted or as we may conduct them in the future or in the markets in which we operate or may in the future operate.

Consistent with the foregoing, we are exposed to a variety of risks, including risks associated with the following:

***Risks Related to Our Business, Financial Condition and Need for Additional Capital***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have incurred significant operating losses in the past and may never achieve or maintain profitability.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We have a limited operating history with our current offerings, which makes it difficult to evaluate our current and future business prospects and increases the risk of your investment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If we are unable to attract new customers on a cost-effective basis, our business will be harmed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may be unable to successfully execute on our growth initiatives, business strategies, or operating plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The forecasts and projections herein are based upon certain assumptions, analyses, and estimates. If these assumptions, analyses, or estimates prove to be incorrect or inaccurate, our actual results may differ materially from those forecasted or projected.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If we fail to attract and retain qualified personnel, our business could be harmed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our management team has a limited history working together operating the Company and, as a result, our past results may not be indicative of future operating performance.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to introduce new products and features is dependent on adequate development resources. If we do not adequately fund our development efforts, we may not be able to compete effectively and our business and operating results may be harmed.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We rely on internet infrastructure, bandwidth providers, data center providers, other third parties, and our own systems for providing solutions to our customers, and any failure or interruption in the services provided by these third parties or our own systems could expose us to litigation and negatively impact our relationships with customers, adversely affecting our brand and our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may not successfully develop or introduce new and enhanced products that achieve market acceptance, or successfully integrate acquired products or services with our existing products, and our business could be harmed and our revenue could suffer as a result.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If we successfully commercially launch the QT Scanner 2000 Model A, (the "***QT Breast Scanner***"), products under development that are cleared by the U.S. Food and Drug Administration (the "***FDA***") and other regulatory agencies, and they do not achieve widespread market acceptance, we will not be able to generate the revenue necessary to support our business.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Recent changes in the United States related to payment policies for imaging procedures could have a negative impact on the utilization of our imaging services.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In order to support the growth of our business, we may need to incur additional indebtedness under our credit facilities or seek capital through new equity or debt financings, which sources of additional capital may not be available to us on acceptable terms or at all.

***Risks Related to Healthcare Industry Shifts and Government Regulation***

iii

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business is subject to extensive pre-market and post-market government regulations and if we fail to comply with present or future regulatory requirements that are applicable, it may subject our company to enforcement action by the FDA which may have a material adverse effect our business, financial condition and results of operations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our products must be manufactured in accordance with federal, state and foreign regulations as to the methods used in, and the facilities used for, the manufacture of our products and if we, or our third-party manufacturers do not take the necessary steps to comply with applicable regulations, it could result in delays in the delivery of our products which could significantly and negative affect the supply of our products.

.***Risks Related to Our Intellectual Property***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our business relies upon a combination of patents and trade secrets to protect the intellection property related to our proprietary technologies and if we are unable to obtain and maintain intellectual property protections it could have an adverse impact on our market competitiveness and business prospects.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Patents have a limited life span and given the amount of time required for the development, testing and regulatory review of products, patents protecting our future products might expire before or shortly after we commercialize these products which could result in us not having sufficient rights to exclude others from commercializing products similar or identical to ours for a sufficient amount of time, and as a result, we may not be able to obtain adequate protection of our patent portfolio.

***Risks Related to Our Management***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We are highly dependent on key members of our executive management team and the loss of members of our management team could result in a delay in the implementation of our business plan and plan of operations, which could result in a material adverse effect on our business, result of operations and financial condition.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Most of the members of our management team have limited or no experience managing a publicly traded company and may not successfully or efficiently manage our transition to being a public company subject to regulatory oversight and reporting obligations under U.S. federal securities laws and the scrutiny of our investors and these obligations could divert their attention away from the management of our business, which could affect our business, financial condition,results of operations and prospects.

***Risks Related to Our Common Stock and Other Securities***

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• It is not currently anticipated that we will pay dividends on shares of common stock, and, consequently, your ability to achieve a return on your investment will depend on appreciation, if any, in the market price of common stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Future sales of common stock may depress their stock price.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We could become subject to product liability claims, product recalls, and warranty claims that could be expensive, divert management's attention and harm our business reputation and financial results.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The public warrants may never be in the money, and they may expire worthless and the terms of the warrants may be amended in a manner adverse to a holder if holders of at least 50% of the then outstanding public warrants approve of such amendment.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may redeem unexpired public warrants prior to their exercise at a time that is disadvantageous to the warrant holder, thereby making the public warrants worthless.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• We may issue additional shares of common stock or preferred stock, including under our equity incentive plan. Any such issuances would dilute the interest of our stockholders and likely present other risks.

**Part I**

**Item 1: Business**

*The following discussion reflects the business of the Company. In this section, "we," "us," "our," "the Company" or "QT Imaging" below generally refers to QT Imaging Holdings, Inc. and its subsidiaries.* 

**Background of the Business Combination** 

On December 8, 2022, GigCapital5, Inc. ("***GigCapital5***"), our legal predecessor company and a special purpose acquisition company which was incorporated in Delaware in 2021, entered into the Business Combination Agreement with its wholly owned subsidiary, QTI Merger Sub, Inc. ("***Merger Sub***"), and QT Imaging, Inc. When the transactions contemplated by the Business Combination Agreement (the "***Business Combination***") closed on March 4, 2024, Merger Sub merged with and into QT Imaging, Inc. with QT Imaging, Inc. the surviving company in such merger, and after giving effect to the Business Combination, QT Imaging, Inc. became a wholly owned subsidiary of GigCapital5, which was renamed as QT Imaging Holdings, Inc.

QT Imaging, Inc. was incorporated in Delaware on December 31, 2020 by converting from its predecessor, QT Ultrasound LLC ("***QT Ultrasound***"), which was a limited liability company formed in 2012 to focus on the research, development, and commercialization of innovative body imaging systems using low energy sound. On that date, QT Ultrasound changed its name from QT Ultrasound LLC to QT Imaging, Inc. and revoked the limited liability company election status by the incorporation.

QT Imaging is headquartered in Novato, California.

**Overview** 

***A Novel Body Imaging Technology***

The Company—with the support of nearly $18<sup>1</sup> million in financial support from the U.S. National Institutes of Health—has developed a novel, comprehensive body imaging technology designed to produce high-resolution volumetric images of breast tissue using low-energy transmitted sound. The technology is based on ultra-low frequency transmitted and reflected sound waves and utilizes a proprietary sound back-scatter design together with inverse-scattering reconstruction algorithms to generate quantitative three-dimensional images of tissue properties.

The Company is a medical device company founded in 2012 and engaged in the research, development, and commercialization of innovative body imaging systems using low energy sound. We believe that medical imaging, and in particular 3D imaging, is critical to the detection, diagnosis, and treatment of disease and that it should be safe, affordable and accessible. Our goal is to improve global health outcomes through the development and commercialization of imaging devices that address critical healthcare challenges with accuracy and precision.

The current standard of care for imaging in breast cancer screening, diagnosis, and treatment is far from satisfactory. Generally, the process starts with X-ray mammography, the primary screening tool for women. Mammography uses radiation, which in sufficient cumulative doses can increase the risk of cancer and requires breast compression, which can be uncomfortable or painful for patients. Callbacks for adjunct screening and diagnosis include ultrasound, magnetic resonance imaging ("***MRI***"), and may include biopsies. This process is expensive, time consuming, and can be stressful for women. In addition, the reliance on multiple imaging modalities reflects the limitations of any single modality in adequately screening for and diagnosing breast cancer.

The Company's opportunity in breast imaging is to shorten the time to diagnosis for women with cancer and to provide reassurance for women who do not have the disease while delivering an improved patient experience and lower cost compared to the current standard of care.

The Company's technology provides automated 3D imaging of the breast without ionizing radiation and without breast compression, enabling high-resolution volumetric imaging and quantitative analysis of breast tissue.

The current QT Breast Scanner, the Breast Acoustic CT™ scanner, developed by the Company is a Class II device subject to premarket notification and clearance under Section 510(k) of the Food, Drug, and Cosmetic Act (the "***FDCA***"). On August 23, 2016, QT Ultrasound submitted a Section 510(k) Summary of Safety and Effectiveness application for the QT

<sup>1</sup> This is comprised of previous grants including grants to the University of Utah ($811 thousand) and the current five year grant 1RO1CA273700 from the U.S. National Institute of Health for $2.58 million (Quantitative Ultrasound Monitoring of Breast Cancer Therapies), which was awarded to 3 institutions: University of Illinois, University of Toronto (Sunnybrook) and QT Imaging, which received $1.08 million of the $2.58 million grant.

Breast Scanner in accordance with 21 CFR 807.92 under 510(k) Number K162372. As part of meeting the general requirements for basic safety and essential performance of the QT Breast Scanner (formerly, QT Ultrasound Breast Scanner) pursuant to AAMI ES60601-1:2005/(R)2012 and A1:2012 Medical Electrical Equipment, testing was conducted by Intertek, an independent testing laboratory located in Menlo Park, CA. Intertek also conducted applicable testing pursuant to IEC 60601-1-6 Edition 3.1 2013-10—Medical Electrical Equipment Part 1-6 General Requirements for Safety—Collateral Standard: Usability. In addition, QT Ultrasound conducted, and Intertek witnessed, all applicable testing pertaining to the requirements for the safety of ultrasonic medical diagnostic and monitoring equipment and to demonstrate compliance with the Acoustic Output Measurement Standard for Diagnostic Ultrasound Equipment. This test on acoustic output was pursuant to IEC 60601-2-37 Edition 2.0.2007—Medical Electrical Equipment—Part 2-37: Particular Requirements for the Basic Safety and Essential Performance of Ultrasonic Medical Diagnostic and Monitoring Equipment. Finally, system verification testing was conducted to ensure that the QT Breast Scanner met all design and other requirements including but not limited to that no new issues of safety or effectiveness compared to the predicate device, the SoftVue System manufactured by Delphinus Medical Technologies, were raised.

On June 6, 2017, the FDA, in response to the Company's Section 510(k) Summary of Safety and Effectiveness premarket notification, determined that the QT Breast Scanner is substantially equivalent to the predicate device under 510(k) Number K162372.

On August 31, 2022, the FDA granted a further 510(k) clearance (K220933) for the Company's QT Scanner 2000 Model A, which enables the system to calculate quantitative measurements of breast fibroglandular tissue volume and the ratio of fibroglandular tissue volume to total breast volume based on reflection-mode and transmission-mode ultrasound images. These measurements may assist clinicians in assessing breast density and monitoring changes in breast tissue over time.

On March 10, 2026, the FDA granted an additional 510(k) clearance for an enhanced configuration of the Company's Breast Acoustic CT scanner designed to improve imaging coverage of posterior breast tissue. The updated configuration incorporates a tilted transmitter geometry, which enhances tomographic visualization of breast tissue located near the chest wall—an area that can be challenging to image with conventional breast imaging approaches. This enhancement expands the scanner's imaging coverage and supports more complete visualization of posterior breast anatomy while continuing to generate volumetric tomographic images using reflection-mode and transmission-mode ultrasound data.

The Company's Cloud software-as-a-service ("***SaaS***") platform will serve as the unified delivery framework for upcoming artificial intelligence and machine learning algorithms developed by the Company. Leveraging DICOM-compatible architecture, the Company will integrate these modules through the cloud for quantitative feature extraction and diagnostic decision support. Built on advanced acoustic signal analysis and volumetric data fusion, the algorithms will be deployed through the cloud infrastructure to enable real-time or near-real-time analysis of imaging data.

This approach will enable future artificial intelligence-driven capabilities, including automated lesion segmentation, volumetric tissue characterization, and computer-aided diagnostic support, to be securely delivered to connected QT Breast Scanners without requiring on-premise software updates. As quantitative biomarkers allow imaging to move beyond detection toward diagnostic and prognostic precision through quantitative imaging, the Company's goal is to build a biomarker-driven Cloud SaaS platform that evolves the business from a hardware manufacturer into a precision imaging platform combining hardware, software, and cloud-based artificial intelligence modules.

***The Purpose of the Company***

Most conventional imaging technologies—including X-ray computed tomography ("***CT***"), MRI, and positron-emission tomography ("***PET***")—typically require complex infrastructure, specialized facilities, and highly trained personnel. These systems often involve ionizing radiation or contrast agents and require shielding and specialized clinical environments. As a result, imaging procedures using these technologies can be time-consuming and expensive and are generally limited to hospital or tertiary care settings.

These limitations restrict access to advanced imaging technologies and make deployment in decentralized or lower-resource environments challenging.

The Company believes its imaging technology platform, which uses low-energy transmitted sound to generate high-resolution three-dimensional images, can address several of these limitations. By avoiding ionizing radiation and eliminating breast compression, the Company's systems are designed to provide a more comfortable patient experience while enabling volumetric imaging and quantitative tissue characterization.

The Company is also developing a cloud-based imaging platform designed to deliver quantitative imaging biomarkers and advanced analytics. Through collaborations with industry partners, the Company is integrating advanced visualization,

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

quantitative analytics, and AI-ready imaging technologies into its Cloud SaaS infrastructure to support clinical interpretation, research workflows, and quantitative imaging analysis. This platform is designed to enable secure cloud-based delivery of Breast Acoustic CT studies with high-performance visualization and multimodality integration across breast imaging workflows.

***The Clinical Problem***

The current medical imaging technologies—CT, MRI and PET—are commonly used in advanced health care facilities in North America, Europe, Japan and South Korea, with more limited deployment in selected tertiary care facilities in other countries—usually large urban areas. These current technologies are based on advanced engineering solutions that use high energy (X-rays, positrons or nuclear magnetic resonance signals) to see inside of the human body. These technologies require large capital investments, are limited to specialized facilities and require advanced certifications for the machines and their operators to insure safe operation. These machines are also expensive to purchase and maintain. All these factors combine to restrict their deployment to advanced clinical centers and tertiary care institutions.

***A Breast Cancer Solution to Increasing the Quality of Health Care and Lowering Costs***

Breast cancer screening today relies primarily on mammography as the front-line modality within the standard breast care pathway<sup>2,3</sup>. While mammography has played an essential role in improving early detection, it is an imaging approach that uses ionizing radiation and, in certain diagnostic contexts such as contrast-enhanced mammography, may require the administration of iodinated contrast<sup>2</sup>. The modality also requires specialized facilities and trained personnel to operate, which can limit access and increase operational costs<sup>2</sup>.

In addition, mammography can be less effective for women with dense breast tissue, where image interpretation is often more challenging and results may be inconclusive<sup>3,4</sup>. This frequently leads to additional supplemental imaging—such as ultrasound or MRI—to clarify findings<sup>3,5</sup>. As a result, many patients experience a multi-step diagnostic process that can involve repeated appointments, multiple imaging modalities, and increased out-of-pocket costs. These factors can contribute to patient anxiety, higher recall rates, and in some cases attrition from recommended screening programs<sup>5</sup>.

These challenges are particularly relevant for women who require regular monitoring but may be hesitant to undergo repeated imaging involving radiation or compression. Concerns regarding cumulative lifetime radiation exposure, procedural discomfort, scheduling complexity, and cost can all impact adherence to recommended screening regimens<sup>5</sup>.

The Company intends to address this gap by establishing its imaging modality as a preferred screening solution for all intermediate-risk women and high-risk younger women (under 40) identified through established risk stratification frameworks such as the Tyrer-Cuzick model<sup>5,6</sup>. Together, these patient segments represent approximately 70% of the screening population, when considering intermediate-risk populations and the large proportion of women with dense breast tissue requiring enhanced screening pathways<sup>3,6</sup>, creating a large opportunity to improve both access and outcomes in breast imaging.

The Company's technology is designed to optimize imaging performance in dense breast tissue while offering an approach that more closely resembles MRI-style physiologic imaging, enabling the capture of multiple physiologic biomarkers in a single examination. These physiologic biomarkers reflect functional characteristics of breast tissue—such as vascular, structural, and mechanical properties—derived directly from imaging data, distinguishing them from molecular biomarkers, which are typically obtained through laboratory or tissue-based testing<sup>7</sup>. This "one scan, multiple physiologic biomarkers" approach can provide clinicians with richer functional insight into breast tissue while reducing the need for multiple follow-on tests.

Beyond the imaging hardware, the Company intends to build and deploy a SaaS precision diagnostics ecosystem around the scanner platform. This ecosystem is designed to generate elevated clinical insights for providers by analyzing physiologic biomarkers derived from the scan data. Specifically, the platform will leverage the geometric, elastic, and spectral properties of breast tissue captured during the scan to produce advanced quantitative assessments that support diagnostic interpretation, longitudinal monitoring, and clinical decision-making<sup>7</sup>. By integrating these capabilities into a

scalable software environment, the Company aims to deliver precision diagnostics that enhance clinical insight while continuously increasing the value of each scanner installed.

Beyond clinical performance, the platform is designed to improve reproducibility through an operator-independent imaging workflow. By minimizing operator variability, the system aims to produce more consistent and reliable imaging results across sites and patient populations.

From an economic perspective, the technology is intended to reduce the overall cost of imaging by lowering capital equipment requirements, simplifying operations, and reducing the need for highly specialized personnel. At the same time, the platform is designed to support revenue growth to providers through access to existing reimbursement pathways for baseline scans, with the potential for additional reimbursement tied to physiologic biomarker–driven precision diagnostic insights delivered through the Company's software platform.

Equally important, the system is designed with patient experience in mind. By eliminating breast compression, ionizing radiation, and contrast injections, the scanning process is intended to be significantly more comfortable and less intimidating for patients. This patient-centric approach may improve adherence to recommended screening programs, reduce anxiety associated with repeat imaging, and support more consistent longitudinal monitoring.

The non-invasive nature of the modality also makes it particularly well suited for therapy monitoring. Because the technology does not rely on ionizing radiation—unlike modalities such as mammography or digital breast tomosynthesis—and does not require contrast agents as in MRI, there are fewer practical or clinical restrictions on how frequently patients can be scanned. This allows clinicians to monitor treatment response more frequently and with greater patient comfort, potentially enabling earlier insights into therapeutic effectiveness.

Through this strategy, the Company aims to complement the existing breast imaging ecosystem while expanding safe, accessible screening and monitoring options for a large segment of the population that remains underserved by current imaging pathways.

**Sales and Marketing** 

The breast imaging market represents a substantial and growing opportunity, with the current total addressable market (TAM) valued at approximately $6 billion<sup>8,9</sup>. This market includes established modalities such as mammography, ultrasound, and MRI, which together form the backbone of breast cancer screening and diagnostics globally<sup>10</sup>,<sup>11</sup>. Within this, the accessible reimbursed markets (SAM)—covering key regions such as the United States, Organization for Economic Co-operation and Development countries, Korea, and Japan—are projected to grow from approximately $1.7 billion in 2025 to $2.6 billion by 2030, reflecting a compound annual growth rate ("CAGR") of roughly 8–9%.

The Company aims to capture meaningful share within this accessible market, targeting approximately 10% SAM penetration by 2030. This represents significant growth potential as the Company's innovative technology advances the breast imaging paradigm.

Moreover, the Company is positioned to participate in a newly emerging market segment valued at around $1 billion, focused on SaaS-enabled precision diagnostics and imaging analytics using physiologic biomarkers<sup>12,13</sup>. This emerging category reflects a broader shift toward AI-enabled quantitative imaging and precision medicine platforms, which enable more personalized treatment approaches with improved therapy guidance and monitoring capabilities<sup>12,13</sup>.

To support this initiative, the Company has entered into strategic partnerships with Intelerad Medical Systems Incorporated ("***Intelerad***") and Olea Medical S.A.S ("***Olea Medical***") to provide the imaging informatics and advanced post-processing infrastructure necessary for physiologic biomarker discovery and clinical deployment. Through its combined hardware and software platform, the Company is uniquely positioned to capitalize on both the expanding traditional imaging market and the emerging precision diagnostics opportunity, driving transformation across breast health care.

***Leverage Current Clearances to Build Presence and Awareness in the Medical Community***

The current QT Breast Scanner is a Class II device subject to premarket notification and clearance under Section 510(k) of the FDCA. The QT Breast Scanner is currently cleared by the FDA under Section 510(k) (which clearance was granted in June 2017) for breast imaging but not as a replacement for screening mammography – currently, the device has FDA approval and can be reimbursed in cases where additional breast imaging is necessary. This includes women who need adjunctive screening, such as: women with dense breasts or where there is a finding; high risk women below the recommended age for mammography; and women who would benefit from more frequent breast imaging, such as women undergoing treatment or women on prophylactic medication to prevent breast cancer.

Many patients may find the QT Imaging modality preferable for dense breasts, implants, post therapy screening where breasts can be very sensitive to compression and where patients have concerns about the radiation dose.

A particular opportunity for the Company under its current clearance is to provide a backup option for women who are recommended for a breast MRI but are unwilling or unable to have it for cost or accessibility reasons. With additional clinical data comparing the clinical efficacy of the QT Breast Scanner to MRIs, the QT Breast Scanner may become a less expensive, more patient-friendly alternative to MRIs (no contrast-dye, no claustrophobia, no noise). QT Scanners will free MRI scanners for other non-breast imaging studies.

Achieving clinical adoption requires building awareness and acceptance in the medical community. The first step will be to place machines with early adopters who see the benefits of the Company's technology, are interested in using the device in their practice, are willing to collect data on its use, and will publish results or speak to their peers about its clinical value.

An example of this strategy in practice is the National Cancer Institute grant received in 2022 in partnership with the University of Illinois – Urbana-Champaign whereby the Company will place a QT Breast Scanner at St. Margaret's Hospital in Toronto, Canada. The objective is to evaluate and measure the effectiveness of the QTscan in evaluation and monitoring cancer treatment in comparison to breast MRI which is currently the standard-of-care in quantitative monitoring

of response to therapy. The results of the study will be published and would represent an independent validation of the clinical value of the QTscan with the imprimatur of a respected university, hospital, and the National Cancer Institute. The Company intends to establish similar peer-review partnerships with respected medical organizations, practices, and practitioners in the future.

***Sales and Marketing Strategy***

Building on its clinical and technology strategy, the Company intends to drive continued growth through a focused commercial expansion plan. In the United States, the Company plans to strengthen its market presence through a hybrid commercialization model that combines strategic collaborations with targeted direct initiatives. A key component of this approach is leveraging its collaboration with NXC Imaging, Inc. ("***NXC***"), a wholly owned subsidiary of Canon Medical USA, Inc. ("***CMSU***"), and CMSU's parent, Canon Medical Systems Corporation ("***CMSC***", and collectively referred to with CMSU as "***Canon***"), which provides access to established sales infrastructure, market relationships, and distribution capabilities. This collaboration will be complemented by the Company's own direct commercial initiatives aimed at expanding clinical partnerships, supporting early adopter sites, and building deeper engagement within the breast imaging community.

As part of its U.S. market development strategy, the Company also intends to undertake a multigenerational outreach and advocacy campaign focused on increasing awareness around breast health and early screening. This initiative will emphasize the theme "Women's Health = Women's Empowerment," positioning proactive health management as a core component of personal and societal empowerment. The campaign is expected to leverage celebrity endorsements and thought leaders to generate earned media exposure and foster broad engagement across multiple generations of women. By combining advocacy, education, and public awareness, the Company aims to encourage earlier and more consistent participation in breast health screening while increasing visibility for new, patient-friendly imaging technologies.

In parallel with its U.S. growth strategy, the Company intends to expand into international markets, beginning with the Gulf Cooperation Council (GCC) region. The Company has established strategic distribution relationships with Gulf Medical Co. ("***GMC***") for the Kingdom of Saudi Arabia and Al Naghi Medical Co. ("***Al Naghi***") for the United Arab Emirates (the "***UAE***"). These partnerships are expected to provide strong regional market access through organizations with deep experience in medical technology distribution and established relationships with leading healthcare institutions.

Regulatory processes for both the Kingdom of Saudi Arabia and the United Arab Emirates are already underway, and the Company expects the required certifications to be in place in the near term, enabling commercial deployment in these markets.

Beyond these initial GCC markets, the Company is actively engaged in discussions to establish additional strategic distribution partnerships across the broader GCC region, including Kuwait, Qatar, Oman, and Bahrain. These markets represent attractive opportunities due to their growing healthcare infrastructure, increasing focus on early cancer detection, and openness to innovative medical technologies.

Looking further ahead, the Company intends to explore expansion into European and other international markets such as Australia and New Zealand (ANZ), South Korea, South Asia, and the Association of Southeast Asian Nations (ASEAN) through carefully selected distribution partnerships. This expansion will be supported by well-orchestrated market creation strategies, including collaborations with leading clinical institutions and research organizations to generate clinical evidence, build physician awareness, and support regulatory and reimbursement pathways in each geography. The Company is also working closely with Canon's Japan operations (where Canon is headquartered) and a prominent luminary in Japan to explore opportunities within the Japanese market. Registration activities for Europe are planned to commence later this year, with other geographies that accept EU registration to be pursued subsequently.

Through this coordinated approach—combining technology innovation, precision diagnostic software capabilities, strong commercial partnerships, and strategic geographic expansion—the Company aims to build a scalable global platform for next-generation breast imaging and diagnostics.

*Use an Installed Base as a Platform to Expand Awareness and Produce Additional Data for Clinical Acceptance, Reimbursement, and Additional FDA Clearances* 

Part of the challenge of achieving clinical acceptance and adoption of the Company's technology is data that proves the efficacy of the QTscan relative to the current standard of care for breast imaging in screening, diagnosis and treatment. The rollout of QT Breast Scanners as described in the previous section will provide multiple means of collecting this data for clinicians, which can also be used to support reimbursement and expanded FDA clearances of the QT Breast Scanner as an alternative to screening breast MRI in younger women (under 40 years of age) with above average risk of breast cancer.

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

Data collection and analysis, support reimbursement and expanding FDA clearances are time-consuming, but with the help of the installations that will be accelerated through the placement programs detailed above, the Company believes that it can achieve these objectives with maximum efficiency.

***Market Segments***

As the installed base for QT Breast Scanners expands, and as discussed above, the Company intends to tailor its marketing efforts towards three segments as it builds awareness and acceptance for its imaging technology. All are important for success, and each requires its own strategy and messaging.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Patients*. This is the end-user/consumer – the women who are dissatisfied with the current scanning model. The Company intends to approach patients through multiple channels, beginning with outreach efforts to recruit key influencers and opinion leaders. These individuals would be recruited through networking and education via targeted interest groups and would become advocates of the benefits of the Company's technology to their respective groups.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Medical Professionals/Radiologists*. In addition to marketing to women, the Company launched an intensive campaign aimed at the medical community. This is a more difficult effort than that aimed at women – from the provider perspective, the need for multiple scans and callbacks that are a negative for patients are actually seen as an economic positive as additional patient visits generate a significant amount of revenue. This is true for both institutions and radiologists, and neither have a great incentive to deviate from the current status quo.

***NXC Distribution Agreement***

The Company is supported by a strong distribution and business partnership with NXC. On May 13, 2023, QT Imaging entered into the "***NXC Sales Agent Agreement***" with NXC, pursuant to which QT Imaging appointed NXC as the non-exclusive agent for the sale of the QT Breast Scanner and related services in non-exclusive territories: the U.S., U.S. territories, and U.S. Department of Defense installations. Additionally, NXC was appointed as the exclusive servicer of the QT Breast Scanners sold by NXC under the terms of the NXC Sales Agent Agreement. Under the NXC Sales Agent Agreement, QT Imaging had the right to set the price for its products and agreed to pay NXC a commission based on the purchase order price charged to a customer. Pursuant to the NXC Sales Agent Agreement, NXC was responsible for promotion and sale of the QT Breast Scanner and related services within the designated territory, as well as servicing the QT Breast Scanners sold by NXC. The initial term of the NXC Sales Agent Agreement was for three years.

Subsequently, effective June 10, 2024, the Company and NXC replaced the NXC Sales Agent Agreement with the "***NXC Distribution Agreement***". Under the NXC Distribution Agreement, NXC is appointed as the exclusive reseller to market, advertise, and resell QT Breast Scanners in the U.S. and U.S. territories. NXC will purchase for the purpose of reselling, leasing or renting QT Breast Scanners directly to its customers, but is not obligated to purchase any particular quantity of QT Breast Scanners from the Company. The Company has reserved the right to sell directly to customers as an exception. Furthermore, the Company may, in its sole discretion, sell the QT Breast Scanners to any other person or entity anywhere in the world without notice to NXC or NXC's prior consent. NXC is also allowed to assign sales agents for the purpose of QT Breast Scanner sales. NXC's purchases will be in accordance with an agreed upon product pricing schedule (subject to change upon 60 days' prior written notice by the Company), provided that neither NXC nor its assigned sales agents may mark-up the cost of the QT Breast Scanners more than twenty percent (20%) unless otherwise mutually agreed to between NXC and the Company. Each order will include information reasonably requested by the Company and is subject to the Company's acceptance, after which it becomes an approved order. Any such approved orders are non-cancellable and not subject to rescheduling after acceptance by the Company. Any orders not accepted by the Company in writing are deemed rejected.

On October 29, 2024, the Company and NXC entered into Amendment No. 1 to the Distribution Agreement (the "***First Amendment***") to expand Section 20 of the NXC Distribution Agreement to provide that NXC shall be obligated to inform its customers who purchase the QT Breast Scanner (the "***Equipment***") that such customers shall not (i) use, copy, distribute, display, perform, or prepare derivative works of any materials accompanying or embodied in the Equipment (except to the extent expressly permitted by such customer's license to such Equipment and its documentation) or (ii) use any Seller Marks (as defined in the NXC Distribution Agreement), in each case without the Company's prior written consent. Further, the First Amendment provides that upon any unauthorized use of the Seller Marks or materials accompanying the Equipment by any customer, NXC shall promptly inform the Company and provide all reasonably requested assistance in termination such unauthorized use.

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

On December 11, 2024, the Company and NXC entered into the Amended and Restated Distribution Agreement (the "***Amended NXC Distribution Agreement")***, which amends and restates the NXC Distribution Agreement in its entirety. The Amended NXC Distribution Agreement provides for the following modifications to the NXC Distribution Agreement, with the balance of terms (including those added by the First Amendment) remaining materially unchanged:

*Sale of Equipment*

Under terms of the Amended NXC Distribution Agreement, in the event that CMSC enters into an OEM manufacturing agreement, then fulfillment by the parties to such manufacturing agreement of their respective obligations under such manufacturing agreement shall be a condition to NXC being the exclusive reseller to market, advertise, and resell the Equipment in the U.S. and U.S. territories.

*Minimum Order Quantities and Pricing*

The Amended NXC Distribution Agreement provides that no later than five days prior to the end of each calendar quarter, NXC shall provide to us a forecast of the anticipated purchases of Equipment during the subsequent twelve-month period. The Amended NXC Distribution Agreement further provides that the forecast for 2025 and 2026 shall be no less than the minimum order quantities ("***MOQs***") set forth in an exhibit to the Amended NXC Distribution Agreement, by quarter and by year. Furthermore, all purchase orders from NXC shall be for no less than the MOQs, which NXC must order on the quarterly and annual basis as set forth in an exhibit to the Amended NXC Distribution Agreement. However, in the event that the Company and CMSC do not enter into an OEM manufacturing agreement, then the MOQs shall be non-binding only in the event that the Company cannot fulfill the manufacture and delivery volumes required for NXC to meet the MOQs.

Should NXC fail to submit a purchase order for no less than the MOQs in any quarterly or annual period, then the Company may invoice NXC and NXC shall pay the Company for the difference between the Equipment purchased and the MOQs for such period.

NXC's purchases will be in accordance with a product pricing schedule attached to the NXC Distribution Agreement as an exhibit (subject to change upon 60 days' prior written notice by the Company). The Amended NXC Distribution Agreement removed the cap on markup by NXC on its resale of the cost of the Equipment that was provided for by the NXC Distribution Agreement, such that NXC may set the resale price for customers at its sole discretion.

*Payment Terms*

Except as otherwise set forth in an applicable Approved Order, the Amended NXC Distribution Agreement provides that we will invoice NXC upon shipment of the Equipment and NXC shall pay the invoice by net thirty days from shipment of the Equipment.

*After Sale Service*

The Amended NXC Distribution Agreement obligates us to continue to provide technical support, spare parts, and necessary know-how in order for NXC to continue to service and support Equipment for at least five years after installation of the Equipment at a customer site. The Amended NXC Distribution Agreement also deleted a provision in the NXC Distribution Agreement that required NXC to request each of its customers to have a qualified or trained breast radiologist.

*Limited Warranty*

The Amended NXC Distribution Agreement contains limited warranties with respect to the Equipment and relevant spare parts, to remain in effect (a) for Equipment for the shorter of fifteen months from the shipment of the Equipment or twelve months from the date of customer acceptance of installed Equipment, and (b) the relevant spare parts for the shorter of twelve months from the date of their shipment and six months from the date that their completion is installed.

*Non-Solicitation*

The Amended NXC Distribution Agreement contains a non-solicitation provision stating that we agree, during the term thereof and for a period of three years after, we shall not, directly or indirectly: (a) interfere with or attempt to interfere with any relationship between NXC and any of its distributors, agents, employees, consultants, independent contractors, agents or representatives, (b) solicit the business or accounts of NXC, or (c) divert or attempt to direct from NXC any business or interfere with any relationship between the NXC or any of its clients, suppliers, customers or other business relations; provided, however, that we may engage with the end customers that have acquired the Equipment to the extent necessary to enable such end customers to utilize the Equipment. Furthermore, to the extent not otherwise prohibited by

law, each party agrees that, during the term of the Amended NXC Distribution Agreement and for a period of three years after, each party shall not, directly or indirectly solicit for employment the employees of the other except to the extent that such solicitation is done through a general advertisement or solicitation that is not specifically targeting the employees of the other.

*Term*

The Amended NXC Distribution Agreement extends the term from December 31, 2025 until December 31, 2026, unless earlier terminated or extended by mutual written agreement.

On March 28, 2025, the Company entered into the First Amendment to Amended and Restated Distribution Agreement (the "***First Amendment to A&R Distribution Agreement***"). The First Amendment to A&R Distribution Agreement amends certain provisions of the Amended NXC Distribution Agreement. It provides, among other things, that the Company reserve the right to sell the Equipment directly to a third party as an exception, and any such direct sale by the Company shall occur after a prior written notification to NXC and shall count towards the MOQs, provided that if a third party is a competitor of NXC as defined in the First Amendment to A&R Distribution Agreement or an existing customer of NXC or NXC's reseller or sales agent at the time when the Company seek to sell the Equipment directly to the third party, the Company may not sell the Equipment to such third party. It also provides that NXC shall provide the Company with the forecast of the anticipated purchases of Equipment during the subsequent twelve-month period no later than forty-five days prior to the end of each calendar quarter, rather than five days prior to the end of each calendar quarter. No changes are made to the amount of the MOQs by the First Amendment to A&R Distribution Agreement, but the MOQs shall not be binding if at any time (a) the Company cannot fulfill the manufacturing and delivery volumes required for NXC to meet the quarterly MOQs, including due to (i) failures or other circumstances attributable to the Company including, but not limited to, issues relating to design or performance of the Equipment (e.g., failure of the Equipment to meet its published specifications), orders by the FDA or another governmental organization to temporarily or permanently suspend shipments, and to activities or operations of the Company, or (ii) a final non-appealable judgment that would impair the Company's ability to fulfill such manufacturing and distribution volumes as a result of (A) intellectual property infringement made by a third party relating to the Equipment or (B) other legal proceedings against the Company; or (b) the Company engage with any competitor or existing customers of NXC or its reseller or sales agent to sell the Equipment in violation of the terms of the Amended NXC Distribution Agreement, as amended. Furthermore, the First Amendment to A&R Distribution Agreement provides that in the event NXC is prevented from selling the Equipment due to actions of or attributable to the Company, the Company and NXC will discuss in good faith. The Company also agreed to introduce at least one new product improvement per year to the Equipment, that the Company will also timely correct all Equipment bugs or other defects as necessary to address performance issues, and that any increases of the price of the Equipment shall be upon mutual agreement of the parties. Also, in the event of an Equipment Recall (as such term is defined in the First Amendment to A&R Distribution Agreement), the First Amendment to A&R Distribution Agreement provides both parties shall promptly consult and cooperate with the other party, including with respect to the appropriate action to be taken in connection with such Equipment Recall, and mutually agree to appropriately modify the MOQs for the respective quarter or until the Equipment Recall is corrected with mutual agreement with NXC.

***Al Naghi Distribution Agreement***

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

On January 19, 2026, the Company entered into an exclusive distribution agreement (the "***Al Naghi Distribution Agreement***") for the Company's QTI Breast Acoustic CT scanners and QTI Cloud SaaS Platform (the "***Al Naghi Approved Products***") in the UAE (the "***Al Naghi Territory***") with Al Naghi, a leading distributor of medical devices.

***Selectively Consider Offshore Marketing Opportunities***

In 2026, the Company will remain focused on realizing and maximizing its potential in the U.S. market as well as in the markets of the Kingdom of Saudi Arabia and the UAE, while also exploring additional distribution arrangements in other GCC countries that accept U.S. product registration. The Company plans to pursue commercialization in Europe and countries recognizing EU registration starting at the end of 2026 and continuing through 2027, utilizing selective distribution arrangements. Additionally, opportunistic sales agency–based deals will continue to be pursued in countries accepting U.S. registration, with the objective of establishing key opinion leaders (KOLs) to drive market creation and evidence generation. These opportunistic deals will be carefully curated, as they may require specialized service support models through existing distribution partners.

***Coverage and Reimbursement***

Over the past few years, the growth rate of advanced imaging volumes has slowed in part due to additional patient-related cost-sharing programs and an increasing trend of third-party payors intensifying their utilization management efforts, for example, through benefit managers who require prior authorizations to control the growth rate of imaging services generally. The Company expects that these trends will continue.

By way of example, in the U.S., the Protecting Access to Medicare Act of 2014 required the Centers for Medicare & Medicaid Services ("***CMS***"), in conjunction with medical specialty societies, to adopt appropriate use criteria ("***AUC***") for certain advanced diagnostic imaging services, including MRI, CT, nuclear medicine (including PET). Beginning in 2020, payment is made to the furnishing professional for an applicable advanced diagnostic imaging service only if the claim indicates that the ordering professional consulted a qualified clinical decision support mechanism, as identified by the Department of Health and Human Services ("***HHS***"), as to whether the ordered service adheres to the applicable AUC. Applicable settings include physician offices, hospital outpatient departments, including emergency departments, ambulatory surgical centers and independent diagnostic testing facilities. Advanced imaging services ordered by certain physicians identified as having outlier-ordering partners will be subject to prior authorization for applicable imaging services provided to Medicare beneficiaries. The outlier methodology used by CMS will be subject to future notice and comment rulemaking before the prior authorization component is implemented. The Company cannot predict the full impact of this project.

The Company is pursuing a phased, multi-year strategy to establish appropriate Current Procedural Terminology ("***CPT***") coding and reimbursement pathways for its QT Breast Scanner and related technology. In 2026, the Company will continue to use the unlisted CPT code 76999, supported by robust documentation and clinical evidence, to facilitate payer education and reimbursement on a case-by-case basis. In parallel, the Company has submitted an application for a New Technology Ambulatory Payment Classification ("***New Tech APC***") to the CMS in September 2025, seeking hospital outpatient reimbursement under the Medicare Outpatient Prospective Payment System ("***OPPS***") framework. This approach will allow the Company to expand clinical use while building the necessary data and adoption to support formal code creation. In November 2025, the Company applied for a Category III CPT code from the American Medical Association ("***AMA***"), which is designed to support emerging technologies and procedures while further evidence is gathered. On Feb 23, 2026, the AMA CPT (Current Procedural Terminology) Editorial Panel approved a new Category III CPTTM code for 3D quantitative transmission volumetric ultrasound tomography of the breast. The new Category III code, X579T, represents a significant milestone in the clinical and commercial advancement of QT Imaging's technology, recognizing the distinct clinical service enabled by its radiation-free, compression-free, 3D breast imaging platform. The new CPT code ensures standardized reporting of this emerging imaging service, supporting data collection, utilization tracking and continued evaluation by clinicians, payers and health systems. The code is scheduled for release on July 1, 2026, with an effective date of January 1, 2027. This staged strategy reflects a deliberate and structured path toward eventual Category I CPT code status, ensuring alignment with payer requirements, coding norms, and clinical integration milestones.

Third-party payors may impose limits on coverage or reimbursement for diagnostic imaging services, including denying reimbursement for tests that do not follow recommended diagnostic procedures or can only be billed using an unlisted or miscellaneous code. To the extent the Company's customers will depend on third-party payors, unfavorable coding, coverage and reimbursement policies may constrict the profit margins of the Company's provider customers, which may force us to lower the Company's fees to attract and retain customers. If the Company is required to request new billing codes that more precisely identify and describe the Company's imaging services, coverage is limited or reimbursement rates are inadequate, a healthcare provider might find it financially unattractive to own diagnostic imaging systems. It is possible that third-party payor coding, coverage and reimbursement policies will affect the need or prices for the Company's products in the future, which could significantly affect the Company's financial performance and the Company's ability to conduct the Company's business.

**Industry & Market Opportunity** 

Doctors and hospitals increasingly rely on medical imaging to screen for and diagnose cancer, guide and monitor treatment such as drugs, radiation, and surgery, and enable minimally invasive procedures. As a result, medical imaging represents a substantial market opportunity. The global medical imaging market is estimated at more than $40 billion annually, with roughly $10 billion attributable to the United States.<sup>14</sup> Global cancer screening, with an approximately $160 billion market size in 2025, is expected to grow at a ***CAGR*** of 12% and reach approximately $470 billion in 2033.<sup>15</sup>

***Breast Imaging*** 

Breast cancer detection and diagnostic technologies (including mammography, MRI, and ultrasound, as well as genetic testing and image guided breast biopsy) are a significant part of the medical imaging market and are estimated to represent a $6.04 billion global market in 2025, is projected to reach $13.2 billion in 2034, with an ongoing CAGR of roughly 9%.<sup>16</sup> The market is segmented by technology, primarily between ionizing breast imaging (e.g., mammography) and non-ionizing breast imaging, which includes ultrasound and MRI. The non-ionizing segment is expected to grow at a faster rate<sup>17</sup> than the ionizing segment due to technological advances such as better segmentation of anatomical detail, higher sensitivity to small breast lesions in women with dense breast tissue<sup>18</sup>, and fewer false positives.

The current standard of care for imaging in breast cancer screening, diagnosis, and treatment is far from satisfactory and may involve certain side effects. There are adverse effects to the use of medical imaging methods such as ionizing radiation, mammography, and MRI. Generally, the process starts with X-ray mammography, the primary screening tool for women. Mammography uses radiation, which in sufficient cumulative doses can increase the risk of cancer; and is uncomfortable or too painful for patients as it involves breast compression. Another adverse effect is the inefficiency of mammography in detection of cancer in women with dense breasts. There is a psychological adverse effect of callbacks for adjunct screening and diagnosis include ultrasound, MRI, and may include biopsies. This process is expensive, time consuming, and can be mentally and physically trying for women. Also, the use of three imaging modalities in the process speaks to the weakness of any one in adequately screening for breast cancer. MRI may take place in a closed environment which may cause claustrophobia, require sedation or general anesthesia and may require injection of a heavy-metal contrast agent. The use of sedation or anesthetic drugs risks severe compromise of respiratory and cardiac function.

Regarding CT, the harmful effects of radiation used in ionizing radiation exposure raises the risk of cancer, including leukemia, breast cancer, thyroid cancer and brain cancer. These issues make MRI preferred to CT for all but trauma evaluation.

The QT Breast Scanner has no reports of adverse effects from the more than 30,000 scans performed to date. Similar to other ultrasound devices, due to the low frequency of the waves of those scanners, there are no known significant risks reported in general clinical practice. The QT Breast Scanner does not require potentially harmful ionizing radiation or anesthesia and is done in an open environment thereby decreasing stress and the necessity of sedation. The QT Breast Scanner does not cause breast implant displacement or rupture.

The Company's opportunity in breast imaging is to speed the time to diagnosis for women with cancer, and to provide assurance for women who do not have the disease with a better patient experience and lower cost than the current standard of care.

While the Company believes women will embrace its technology, the Company is focused on achieving clinical adoption through the medical community, which requires continuing research on the clinical efficacy of the images rendered by the QT Breast Scanner known as a QTscan® image and development of key opinion leaders ("***KOLs***") who can speak to the clinical value of its machines in practice.

There are three primary technologies within the non-ionizing breast imaging segment: Automated Breast Ultrasound Systems or ABUS (as defined below); Breast Ultrasound Tomography Systems; and Photoacoustic Imaging.

*Automated Breast Ultrasound Systems ("ABUS")* 

*ABUS* are an emerging and rapidly growing segment of the breast imaging market. ABUS systems are designed to improve cancer detection in women with dense breast tissue by providing standardized, operator-independent whole-breast ultrasound imaging as a supplement to mammography. Increasing recognition of the limitations of mammography for women with dense breasts, along with regulatory requirements for breast density notification in many jurisdictions, has driven growing clinical adoption of ABUS technology. As a result, the global ABUS market is estimated to exceed $1 billion in the mid-2020s and is projected to grow at a CAGR of roughly 13–16% in the coming years, reflecting continued expansion of breast cancer screening programs and demand for supplemental imaging modalities.<sup>19</sup>

ABUS technologies typically use a reflection transducer<sup>20</sup> (5-15 MHz) and not transmitting setup, in a "motorized" arrangement. The major developers of such systems include: 1) the Acuson S2000 ABVS (sold by Siemens); 2) the Invenia System (sold by GE Healthcare); 3) a manual video loop AWBS System (sold by Sono-Cine); and 4) a motorized single transducer Sofia System (sold by Hitachi.). All of these systems produce B-mode reflection images<sup>21</sup>.

*Breast Ultrasound Tomography Systems* 

These technologies use traditional reflection transducers<sup>22</sup> in an "array" configuration around the breast: 1) Mastoscopia (Greece); 2) the KIT system (research only) from Karlsruhe University in Germany; and 3) the Delphinus System.

*Photoacoustic Imaging* 

Photoacoustic imaging systems utilize lasers to excite tissues and produce acoustic energy that subsequently create images of the breast vasculature.<sup>23</sup> Such systems include both photoacoustic tomography ("***PAT***") and photoacoustic imaging ("***PAI***") systems. While the PAT systems allow volumetric imaging by reconstructing stacks of 2D images, the PAI systems only allow superimposition of photoacoustic signal information on top of conventional B-mode ultrasound. Note that in comparison to ultrasound, photoacoustic imaging systems inherently lack the ability to image the tissue anatomy and

*https://www.futuremarketinsights.com/reports/automated-breast-ultrasound-system-market* (2025).

<sup>20</sup> A medical reflection transducer, also known as an ultrasound transducer, is a device that converts electrical energy into sound waves, and the back again into electrical energy. It is used in medical imaging to produce images of internal organs and tissues in the body, and it is used in various medical imaging techniques such as ultrasound, echocardiography and Doppler imaging. See, e.g., ECG & ECHO Learning, The Ultrasound Transducer, available at https://ecgwaves.com/topic/the-ultrasound-transmitter-probe/ (last visited Apr. 4, 2023); see also, FDA, Ultrasound Imaging Sept. 28, 2022), https://www.fda.gov/radiation-emitting-products/medical-imaging/ultrasound-imaging.

<sup>21</sup> B-mode ultrasound, also known as 2D ultrasound, is a type of ultrasound imaging where "a linear array of transducers simultaneously scans a plane through the body that can be viewed as a two-dimensional image on screen."

<sup>22</sup> Medical reflection transducer, also known as an ultrasound transducer, is a device that converts electrical energy into sound waves, and the back again into electrical energy. It is used in medical imaging to produce images of internal organs and tissues in the body, and it is used in various medical imaging techniques such as ultrasound, echocardiography and Doppler imaging.

<sup>23</sup> Breast vasculature refers to the blood vessels that supply and drain blood from the breast tissue. The breast is a highly vascularized organ, and the blood supply comes from a network of arteries and veins that run throughout the breast tissue. See, NIH, National Library of Medicine, Yusuf S.

essentially only image the vasculature (i.e., blood, which is a strong absorber of light). For PAT systems, there is no clinical trial data available (to our knowledge) and no PAT systems have been approved for clinical use. For PAI systems, the Imagio Breast Imaging has been used in clinical trials and is FDA cleared to be used as an adjunct to conventional handheld breast ultrasound.

All of these technologies face challenges to expansion, including FDA clearances and insurance reimbursement. However, the shortcomings of other imaging methods such as ionized radiation exposure, high costs and deployment challenges of MRI, and the inefficiency of mammography in detection of cancer in women with dense breasts, are sufficiently compelling for industry to address these obstacles, and these shortcomings will continue to create an opportunity for development and commercialization of advanced screening systems such as the Company's.

***QT Breast Scanner***

*The Need: A safe, painless imaging device that provides conclusive breast health assessment* 

<u>Background:</u>

Breast cancer is the most commonly diagnosed women's cancer in the United States, according to the National Cancer Institute. The American Cancer Society estimates that in 2022, 287,850 women in the United States have been diagnosed with invasive and in situ (early stage) breast cancer, and breast cancer has claimed the lives of 40,920 women.<sup>24</sup> The American Cancer Society further estimates that one out of every eight women will develop breast cancer at some point during her life and one in every 42 women who turns 50 today will have a diagnosis of breast cancer before she turns 60.

There are several dominant screening and diagnostic technologies that are used both independently and dependently to locate cancers at an early stage and improve treatment outcomes. Each of the currently available non-surgical modalities for breast cancer detection has various clinical limitations. Screening methods and technologies include: (i) breast self-examination and clinical breast examination; (ii) mammography, including screening mammography, diagnostic mammography, and mammography with computer aided detection; (iii) Hand-Held Ultrasound ("***HHUS***") and (iv) MRI.

<sup>24</sup> See, American Cancer Society, Breast Cancer Facts & Figures, available at *https://www.cancer.org/research/cancer-facts-statistics/breast-cancer-facts figures.html* (last visited Feb. 10, 2023).

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

Mammography is the dominant imaging modality in today's standard of care. The American Cancer Society recommends that women of average risk have the option to begin mammography at age 40, get mammograms every year from age 45-54, and have mammography every other year starting at age 55.<sup>25</sup> Despite those recommendations, only 65% of women over 40 in the United States have had a mammogram in the previous two years, and only 58% of women between 40 and 49 had a mammogram in the previous two years,<sup>26</sup> even though screening mammography is 100% covered under the Affordable Care Act. This is in part due to the limitations of mammography, both in terms of sensitivity and reliability for dense breast tissue, where 10-15% of cases have inconclusive results requiring further testing, as well as concerns about safety. Mammography is also problematic in women who have breast implants. For these women, problems include painful mammograms, delayed detection of cancer from interference in imaging breast tissue, and an unwillingness to perform mammograms due to fear of implant rupture, dislocation or capsular contracture.

The Company's goal is to provide highly accurate, 100% safe, radiation-free and painless breast imaging that can be used to:

1)identify cancer early to minimize invasiveness and increase effectiveness of treatment; and

2)eliminate unnecessary intervention (additional imaging and biopsies) for women with benign breast conditions.

*The Product, QT Breast Scanner* 

The QT Breast Scanner is a fixed, stationary, mechanical scanner used to evaluate the breast without the use of either ionizing radiation or compression associated with mammography, or the injections required for breast MRI. With the QT Breast Scanner, the patient lies comfortably on a table which contains an opening through which the breast is immersed in a warm water bath (see Image 1) and gently immobilized using a magnetic retention pad fixed to a magnetic rod.

The QT Breast Scanner

![image1A.jpg](qti-20251231_g2.jpg)

Image 1

Surrounding the warm water bath is a dual modality reflection and transmission ultrasound array that rotates 360 degrees around the breast (see Image 2 & Image 3) to produce 3D images. The ultrasound array produces low energy, low frequency sound waves (non-radiation "pressure waves") through the breast and reflecting from the breast, with both collecting volumetric (3D) data. Reflection data is collected on the transducer facing side, and the transmission data is collected on the back side of the breast. The transmission data quantitatively measures the velocity of these pressure waves through the breast. This information can be used to generate a true 3D image of the breast and all its tissues.

The QT Breast Scanner differs from the handheld ultrasound used in breast imaging in that it utilizes reflection and transmission data from low-frequency sound waves, providing increase in diagnostic information using the speed of sound characteristics of the breast and acquiring in true 3D a very accurate rendering of the breast tissue. The QT Breast Scanner

provides sub-millimeter, high-definition, image resolution enabling identification of normal and abnormal breast structures and the accurate depiction of the precise shape and location of findings.

Technology uniquely quantifies breast density using transmission information to further personalize a patient's management recommendations. Surface-to-volume ratios and volumetric doubling time growth rate characteristics can be calculated to determine significance of lesions and improve specificity of the ultrasound.

Image 2: Schematic of transmission and reflections modes

The QT Breast Scanner creates true 3D images of the patient's breast viewable in the Quantitative Transmission Ultrasound Viewer (known as QTviewer®), a software product designed for healthcare professionals to view the transmission (speed of sound) and reflection images. This application can display correlated Digital Imaging and Communications in Medicine ("***DICOM®****") images* in multiple orientations (coronal, sagittal, and axial). QTviewer can manipulate image views and analyze pixel data with various functions. The QTviewer has additional functionality which enables the user to measure mass size and volume as well as fibroglandular tissue volume.<sup>27</sup>

The QT Breast Scanner is the current version of the QT Breast Scanner and is FDA-cleared "for use as an ultrasonic imaging system to provide reflection-mode and transmission-mode images of a patient's breast. The QT Scanner 2000 Model A software also calculates the breast fibroglandular tissue volume (FGV) value and the ratio of FGV to total breast volume (TBV) value as determined from reflection-mode and transmission-mode ultrasound images of a patient's breast. The device is not intended to be used as a replacement for screening mammography."<sup>28</sup> The QT Breast Scanner has current applicability as a supplementary imaging device (not as a replacement for screening mammography) and for determining the ratio of fibroglandular tissue volume to total breast volume which is a measure of breast density; near-term applicability for automatic segmentation of lesions followed by measuring lesion stability/growth, and diagnosing lesions using artificial intelligence; and medium- to long-term applicability for breast cancer screening as shown in Table 1.

**Manufacturing** 

Prior to the third fiscal quarter of 2025, the Company's products have solely been manufactured in Novato, California. With the entry into the Canon Manufacturing Agreement as discussed below, the Company is, beginning with the third fiscal quarter of 2025, manufacturing the QT Breast Scanners in parallel between Novato, California and using CMSC as a contract manufacturer pursuant to the Canon Medical Agreement. The products are designed under the FDA's design control guidelines and manufactured in accordance with the Company's quality management system.

The Company's devices are made up of custom designed components and off-the-shelf components, both of each are supplied by the Company's approved vendors in the U.S.

For those QT Breast Scanners manufactured by the Company in Novato, California, the subassemblies are manufactured at the Company and verified prior to the final assembly of the device. The controls software and image reconstruction software are loaded on the imaging devices at the Company's facility in Novato. Prior to shipping, 100% of the products are verified for functionality, performance, and safety.

The Company intends to scale up its production by initially using CMSC, and may also look at strategic original equipment manufacturing ("***OEM***") agreements for large production throughput.

The suppliers that the Company purchases from and engages with are limited to those that are approved by our Quality Assurance department, which maintains an Approved Supplier List. The Company categorizes suppliers into three groups: (i) non-critical, (ii) important, and (iii) critical. For example, our "non-critical" suppliers include general distributors and/or suppliers of commercially available "off-the-shelf" items such as mechanical and electrical standard hardware, blank label stock, seals and labeling pouches, and our "important" suppliers include custom component suppliers, test facility providers and consultants.

Before a supplier is classified as "critical," the Company assesses the supplier's: (a) specific or proprietary core competencies, (b) tooling costs and lead time, and (c) product delivery lead time. Any supplier whose processes or products are required by the Company to be validated are classified as "critical." Another factor that the Company considers is the lead time to approve an alternative supplier. As of the date of this annual report, although there are various suppliers in the U.S. and abroad that can produce high quality ultrasound transducers for the Company, the Company has only engaged in the supplier validation and approval process with one such supplier which manufactures ultrasound transducer subcomponents in accordance with the Company's specifications. Because the Company has validated this supplier, but has not undertaken the significant commitment of resources to validate and approve other such suppliers of ultrasound transducers, despite the fact that the Company could choose to do so, it considers this supplier as being "critical" on our Approved Supplier List but not a principal supplier. In addition, as of the date of this annual report, the Company does not have written agreements in place with this critical supplier, and is operating under an individual purchase order platform, on an as-needed-basis; however, the Company may enter into such agreements in the future.

***Canon Letter of Intent***

QT Imaging entered into the Canon Letter of Intent with CMSU and CMSC pursuant to which CMSC purchased and acquired two QT Breast Scanners in the first half of 2024. The Canon Letter of Intent provided that CMSC would conduct, and pursuant to the Feasibility Study Agreement (as described below), CMSC conducted, feasibility studies on the QT Breast Scanners that it acquired, including product quality validation, development and manufacturing studies, clinical evaluation, regulatory investigation and marketing validation (the "***Feasibility Study***") The Feasibility Study was completed in the second half of 2024.

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

The Canon Letter of Intent provided that upon successful conclusion of the Feasibility Study, we and CMSC intended to engage in a good faith discussion to develop a binding OEM manufacturing agreement with CMSC, which we have now done, as discussed below.

CMSC will also use QT Breast Scanners that it acquired to perform clinical trials towards the possibility of it pursuing the regulatory approval process in Japan.

CMSC and QT Imaging have also discussed other potential terms between them.

***Feasibility Study Agreement with Canon Medical Systems Corporation***

On March 28, 2024, the Company entered into the Feasibility Study Agreement with Canon. The term of the Feasibility Study Agreement commenced on March 28, 2024 and by its terms, remained in force until the end of December 2024. In connection with the Feasibility Study Agreement, Canon initiated studies to evaluate the business, technical, and clinical values of the Company's QT Scanner including product quality validation, development and manufacturing studies, clinical evaluation, regulatory investigation, and market validation. Canon has no right to reverse engineer the QT Scanner and may only modify and disassemble the QT Scanner as necessary to conduct the Feasibility Study.

Under the terms of the Feasibility Study Agreement, the Company provided support for the Feasibility Study as agreed with CMSC from time to time during the term of the Feasibility Study Agreement and used its commercially reasonable efforts to facilitate the feasibility study. Both parties confirmed that the support provided by the Company did not result in significant costs to the Company, as it only provided technical materials and knowledge that it already possessed and did not involve the creation of new materials or engineering. Each party was responsible for covering its own expenses related to the Feasibility Study and the support, except if the parties agreed in writing otherwise, one party shall pay to the other party an amount reasonable under the circumstances.

The Feasibility Study Agreement provided that all know-how and intellectual property embodied in the QT Breast Scanner are owned by the Company and all rights not expressly granted to the Company are reserved.

***Canon Manufacturing Agreement***

On March 28, 2025, the Company entered into the Canon Manufacturing Agreement with CMSC. Pursuant to the terms of the Canon Manufacturing Agreement, the Company appointed CMSC as the exclusive manufacture of the QT Breast Scanners to be distributed by NXC pursuant to the Amended NXC Distribution Agreement. CMSC's manufacturing of the QT Breast Scanners shall not include the final testing process for the QT Breast Scanners, and CMSC shall not have any responsibility for the QT Breast Scanner as a manufacturer of medical equipment for FDA purposes.

In order for CMSC to manufacture the QT Breast Scanners, the Company shall sell components to CMSC in a timely manner, in accordance with agreed-upon terms and conditions. The Company shall cooperate with and support CMSC to allow CMSC to procure components through its own supply chain. The parties shall negotiate in good faith specific procedures to phase out CMSC's purchase of components from the Company, with the target date of the fourth quarter of 2025, although this is not a commitment. The terms for purchasing components (or subassemblies), including components for service, by the Company from CMSC shall be mutually agreed upon by the parties.

The Company shall provide forecasts to CMSC in accordance with the "Forecast Policy" attached to the Canon Manufacturing Agreement. No later than forty-five days prior to the end of each calendar quarter, CMSC will notify the Company in writing if CMSC is unable to deliver a sufficient number of QT Breast Scanners to satisfy the forecast for the following quarter. If CMSC is unable to deliver a sufficient number of QT Breast Scanners due to CMSC's willful misconduct, CMSC will sell back to the Company all components necessary for the Company to engage in Novato Manufacturing of the QT Breast Scanners for the following quarter at the Company's facility in Novato, California sufficient to cover the QT Breast Scanner shortfall back at the same purchase price that CMSC paid to purchase such components. CMSC shall bear risk of loss, all fees and shipping costs for the components incurred in connection with such Novato Manufacturing.

No later than forty days prior to the end of each calendar quarter, the Company shall notify CMSC in writing indicating whether or not the Company wishes to engage in Novato Manufacturing of the QT Breast Scanners for the following quarter for the purpose of meeting the forecast for such quarter. If the Company provides such notice to CMSC within the 40-day period, stating that the Company wishes to engage in Novato Manufacturing, the Company may purchase from CMSC (if the Company does not already have) any components held by CMSC necessary as determined by the Company for the Company to be able to manufacture the QT Breast Scanners via the Novato Manufacturing, at the same purchase

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

price that CMSC paid to the Company to purchase such components. The Company shall bear all risk of loss, fees and shipping costs for the components incurred in connection with the Novato Manufacturing.

From time to time during the term of the Canon Manufacturing Agreement, but no later than thirty days prior to the delivery date specified in the purchase order, the Company may issue to CMSC a purchase order for any of the QT Breast Scanners necessary to meet the forecast, for the actual quantities to be delivered by CMSC. Each purchase order shall specify delivery dates that respect the "Forecast Policy." The purchase prices applicable to the purchase orders as of the date of the Canon Manufacturing Agreement shall be separately agreed between the parties in writing. CMSC may reject any purchase order that requests delivery dates that are not in compliance with such Forecast Policy. Unless the Company is manufacturing QT Breast Scanners as Novato Manufacturing, any failure by CMSC, as a result of CMSC's conduct, to manufacture and deliver QT Breast Scanners as specified in an accepted purchase order necessary to satisfy the forecasts later than seventy-five days from the delivery date as specified in the accepted purchase order shall result in liquidated damages per missed or delayed QT Breast Scanner of $220 thousand, with NXC not being obligated to pay for the missed MOQ sale. Such failure by CMSC shall also not provide any grounds for NXC to terminate the Amended NXC Distribution Agreement or otherwise cancel the binding nature of the MOQs as provided in the Amended NXC Distribution Agreement. All title to and risk of loss of the QT Breast Scanners shall pass from CMSC to the Company when the QT Breast Scanners have been delivered to the Company in Novato, California, under the Incoterms 2020 trade term, DDP. The Company shall make payment of the QT Breast Scanners to CMSC within ninety days after the issuing date of an original copy of the invoice to be issued by CMSC.

Prior to the delivery of the QT Breast Scanners, CMSC shall inspect and test all the QT Breast Scanners in accordance with the outgoing test procedures to be approved in writing by the Company and as specified in the specifications or otherwise to be separately agreed upon between the parties in writing. The Company shall perform the visual, quantity and/or quality inspection of the QT Breast Scanners upon their receipt. If any of the QT Breast Scanners delivered is found deficient in quantity (as set forth in the accepted purchase order), or is defective in material and workmanship or inconformity with the specifications, and such deficiency, defect or non-conformity is caused by CMSC, the Company may submit a written claim notice to CMSC with sufficient supporting evidence, including but not limited to photographs and reasonably detailed explanation. CMSC shall, at its sole discretion, either (i) deliver additional QT Breast Scanners to fulfil the required quantity or deliver replacement of the QT Breast Scanners, or (ii) offer an equitable reduction in the purchase price of the QT Breast Scanners delivered, subject to mutual agreement between the parties. CMSC is providing a warranty on the QT Breast Scanners that they shall be free from defects in material and workmanship and conform to the specifications for a period of (i) twelve months from the delivery date of each QT Breast Scanner from the Company to NXC, or (ii) twelve months from the installation date for the QT Breast Scanners directly sold to end users by the Company. If any defects in material and workmanship, or non-conformity of the specifications occur during the warranty period and the Company provides a timely claim, CMSC shall, at its sole discretion (i) send a replacement of a part(s), (ii) send a brand new QT Breast Scanner as a replacement, (iii) repair the defective QT Breast Scanner(s) and return them to the Company, or (iv) refund the equivalent price to the purchase price. CMSC shall only be responsible for recalls resulting from the manufacturing process of the QT Breast Scanners or materials and parts procured by CMSC (other than materials and parts procured from the Company).

All intellectual property rights, including but not limited to patents, copyrights, know-how, and trade secrets (the "***IPR***"), which each party has owned before entry into the Canon Manufacturing Agreement or develops separately from the performance of the manufacture of the QT Breast Scanners under this agreement, shall remain the exclusive property of the Company or CMSC respectively. All IPR in and to any invention, whether patentable or not, conceived and reduced to practice in the performance of the manufacture of the QT Breast Scanners under the Canon Manufacturing Agreement shall be owned solely by CMSC; provided, that to the extent that such invention is based on the Company's confidential information and is exercised on the QT Breast Scanners which are manufactured by CMSC and delivered to the Company, such as manufacturing process flow, CMSC agrees not to assert any IPR in and to such invention against the Company, its affiliates and customers as to the QT Breast Scanners. All IPR to and in any invention, whether patentable or not, if agreed between the parties to have been conceived and reduced to practice jointly by the Company and CMSC in the performance of the manufacture of the QT Breast Scanners shall be owned jointly and equally by the Company and CMSC, and both parties shall have the right to use, utilize and exploit such IPR in accordance with applicable laws involved without a prior consent of or any payment or consideration to the other party.

The Company grants to CMSC a personal and exclusive license to use, utilize (including copy, amend, revise and modify) and exercise the IPR owned by the Company solely for enabling it to manufacture the QT Breast Scanners sold to NXC and provide maintenance support for them, provided that (i) such exclusive license may be sublicensed to NXC and other subsidiaries of CMSC and/or authorized maintenance companies (with such authorization to be provided in writing by the Company, but not to be unreasonably refused, withheld, or delayed) that provide maintenance services on an outsourced

In the event of "Change of Control" of a party, either party shall have the right to, at its sole discretion, terminate the Canon Manufacturing Agreement in its entirety upon forty-five business days' prior written notice to the other party. Such notice shall be provided prior to the expiration of the then current term of the Canon Manufacturing Agreement. In the event of the termination or expiration of the Canon Manufacturing Agreement, CMSC will honor all of the outstanding accepted purchase orders, and both parties will cooperate to fulfill such orders. In the event that either party substantially fails to comply with any provision of the Canon Manufacturing Agreement and that such non-compliance has not been cured within thirty business days from the date of its receipt of the written notice from the other party, then the other party shall have the right to terminate the Canon Manufacturing Agreement upon giving a written notice. The Canon Manufacturing Agreement also provides other grounds for its termination prior to December 31, 2026, including by CMSC if NXC's sales of the QT Breast Scanner are adversely affected due to any failures or other circumstances attributable to the Company that the Company is or is reasonably expected to be unable to remedy (including but not limited to Epidemic Failures; the submission of Medical Device Reports (MDRs) to the FDA regarding the QT Breast Scanner; any action by the Company (either voluntarily or upon an order or request by the FDA) to conduct a Field Correction, Market Withdrawal, Stock Recovery, or Recall (as such terms are defined by the FDA); any action by the Company or any regulatory authority to temporarily suspend shipments or manufacturing of QT Breast Scanners; or issues related to the Company's business operations) within six months from the date of the onset of such an event. For these purposes, "Epidemic Failures" means a malfunctioning of five or more QT Breast Scanners collectively presumed to have a common underlying cause based on a reasonable evaluation. Following a termination or expiration of the Canon Manufacturing Agreement, the provisions with respect to the grants of licenses to the IPR of the Company will survive up to the earlier of (a) the end of the five-year lifetime of the QT Breast Scanners sold to NXC and (b) December 31, 2031.

**Clinical Studies**

The Company has conducted or collaborated on several clinical studies to evaluate the imaging performance of the Company's Breast Acoustic CT scanner. These include clinical studies that compared the Company's technology with standard breast imaging modalities: full-field digital mammography ("***FFDM***"), digital breast tomosynthesis ("***DBT***"), and MRI. We highlight several of the most significant studies below, which span three related areas of performance: recall rates, diagnostic characterization, and supplemental screening.

<u>Recall Rates</u>:

Background: Mammography has a low positive predictive value. Overlying fibroglandular tissue can mask a cancer, especially for women with dense breasts. It can also cause summation artifacts, resulting in false-positive findings and more recalls. Studies show that mammography leads to unnecessary follow-up procedures — such as handheld ultrasound or MRIs and biopsies — leading to unnecessary patient anxiety, costs, and time. For every 1,000 screening mammograms, 150 women are called back for more tests but only three are diagnosed with cancer. Given the need to reduce unnecessary recalls, the Company evaluated the recall rates of the Company's Breast Acoustic CT scanner compared with mammography.

Study:

An Exploratory Multi-reader, Multi-case Study Comparing Transmission Ultrasound to Mammography on Recall Rates and Detection Rates for Breast Cancer Lesions. Academic Radiology Vol 29 – Supplement 1 S10-S18, Jan 2022; https://doi.org/10.1016/j.acra.2020.11.0.11 and https://www.academicradiology.org/article/S1076-6332(20)30646-2/fulltext. In consultation with Cytel (Cambridge, MA), the Company designed, conducted, and funded this retrospective trial.

An exploratory, multi-reader, multi-case study evaluated radiologists' performance on lesion detections and non-cancer recall rates for the Company's Breast Acoustic CT platform versus standard full-field digital mammography, using retrospective data from two case collection clinical trials conducted at five sites between 2006-2018. All subjects received both FFDM and QTscans within 90 days. Data were analyzed in a reader study with full factorial design involving 22 radiologists and 108 breast cases (42 normal, 39 pathologically-confirmed benign, and 27 pathologically-confirmed cancer).

This MRMC study found that the readers' mean rate of detecting lesions of any type was 4% higher (p-value > 0.05) with QTscans compared with FFDM. The study also found that QTscans significantly decreased the mean non-cancer recall rate by 16% (p-value = 0.03) at the expense of a 2% decrease in the mean cancer recall rate (p-value > 0.05), compared with FFDM. In summary, this exploratory MRMC study indicates that QTscans improve non-cancer recall rates without substantially affecting cancer recall rates.

<u>Diagnostic Characterization</u>:

Background: Patients often go through follow-up procedures, such as a HHUS scan, to identify whether screening mammography (FFDM or DBT) findings are due to a cyst or solid lesion. HHUS can improve cancer detection, particularly for the peripheral regions of the breast and axilla. However, HHUS is not suitable for primary breast screening, and its 2D nature leads to a low specificity and high number of false positives. HHUS is also very operator dependent, with reproducibility issues that impact diagnostic accuracy. Thus, an alternative, more accurate, automated imaging modality is needed to distinguish between cysts and solids.

Many patients also require additional follow-up imaging, such as an MRI, to further identify and characterize lesions in order to distinguish between benign and malignant masses. For example, mass morphology (such as irregularity and circulatory), dimensions, and characteristics are commonly used to differentiate benign from malignant breast masses. Critical to diagnosis and treatment decisions, alternative breast imaging options are needed for mass characterization when an MRI is not feasible due to availability or patient contraindications.

the Cleveland Clinical Foundation. It was supported by the Company and a grant from the National Cancer Institute R01CA138536.

A retrospective multi-reader, multi-case receiver operating characteristics study evaluated the diagnostic accuracy in determining whether a breast lesion is a cyst versus a solid, using the Company's Breast Acoustic CT platform as an adjunct to mammography. Fourteen readers performed blinded, randomized reads with digital mammography and QTscan images — assigning both a binary classification of cyst versus solid and a confidence score (0-100; where 0 represents 0% confidence that lesion is solid or 100% that it is a cyst). A 95% bootstrap confidence interval (CI) was also computed for the readers' mean receiver operating characteristic area, sensitivity, and specificity.

Using the readers' binary classification of cyst or solid lesions, this MRMC study found that the mean sensitivity was 93.3% (95% CI: 83.7, 99.5) and the mean specificity was 85.8% (95% CI: 70.1, 98.5). When the readers' confidence scores were used to distinguish a cyst versus a solid, the mean receiving operating characteristics area was 0.92 (95% CI: 0.927, 0.985). In summary, this MRMC study demonstrates that QTscans are highly accurate at diagnosing a cyst versus a solid lesion, suggesting that QTI technology can be used as an adjunct to mammography to improve specificity in breast evaluation.

This study was conducted by the Sunnybrook Health Sciences Centre in Toronto, Canada and registered on ClinicalTrials.gov (NCT06175078). It was funded by the National Institute of Health grant RO1CA273700-01.

This prospective, single-center, observational, early validation study evaluated the use of QTscans in detecting, characterizing, and measuring the volume of breast masses in comparison to MRI. The study was conducted in a cohort of 20 female patients: 16 patients with biopsy-proven malignant breast tumors and 4 patients with biopsy-proven benign lesions. The comparative analysis between QTscans and MRI evaluated key quantifying metrics for breast mass characterization, including breast mass morphology, dimensions, and characteristics.

This study's findings indicate some differences in lesion characterization between the two imaging modalities. Nevertheless, QTscans demonstrated good performance in identifying relatively small tumors, multiple lesions, satellite lesions, intraductal extensions, and calcifications, as well as offering valuable diagnostic insights. MRI with contrast offered a broader distribution in size classification, providing useful insight into areas for continued development and optimization for QTI technology. In summary, the study found good overall agreement between MRI and QTscans for assessing breast mass volume in most cases. These results suggest that QTscans could excel in specific diagnostic scenarios — particularly when evaluating advanced or multifocal disease — and may serve as an important alternative breast imaging option when MRI is not feasible due to availability or patient contraindications.

<u>Supplemental Imaging</u>:

Background: Mammography (FFDM and DBT) are the standard screening modality for breast cancer. In addition, supplemental screening with MRI is also standard for women at elevated risk of breast cancer — based on risk factors such as a personal or family history, first-degree family genetics, history of radiation to the chest before age 30, and/or having dense breasts. In the US, 40%-50% of women ages 40-74 have dense breasts, and it's even more common for young women. Having dense breasts means that a women's breasts have a higher portion of glands, ducts, and connective tissue compared to fatty tissue, which makes it more difficult for a mammogram to detect cancer. Although MRIs can locate breast lesions missed by mammography and in younger women, breast MRIs also have limitations. In particular, some women cannot get breast MRIs because they are allergic to the gadolinium-based contrast agents, have impaired renal function, or are pregnant or breast feeding. An alternate breast imaging modality is needed for supplemental screening, particular for women with high risk.

This prospective, case-collection study was conducted at four clinical sites. It enrolled adult women with either normal or abnormal mammograms who received a standard clinical digital breast tomosynthesis followed by a QTscan within 90 days. The study collected and analyzed a total of 177 single-breast image cases (66 with cancer atypia or solid mass and 111 normal or with nonsolid benign abnormality). After receiving QTI training, 24 radiologists interpreted the 177 cases for QTscans first and then for DBT synthesized 2D-views two weeks later. The readers reported up to three findings per case, identifying a recall or no recall decision and confidence score of that decision for each finding. A MRMC ROC analysis was performed to test for the noninferiority of QTscans to DBT. The sensitivity and specificity were estimated from the readers' call-back versus no call-back decisions.

This MRMC ROC study demonstrated that the Company's Breast Acoustic CT scanner is noninferior to DBT in terms of ROC analysis and the Area Under the Curve (mean AUC for QTscan of 0.746 vs. 0.700 for DBT; p-value < 0.05). While sensitivity slightly decreased for QTscans (70.6% for QTscans vs. 85.2% for DBT), specificity improved significantly (60.1% for QTscans vs. 37.2% for DBT). The study also showed the recall rate of benign cysts improved substantially. In summary, this MRMC observer performance study demonstrates that QTscans improve recall and lesion detection with higher specificity and less false positives compared with DBT, suggesting QTI technology's potential as a supplemental imaging tool, particularly for women too young to undergo mammography.

Comparison of Quantitative Transmission Imaging and MRI for High-Risk Screening of Breast Cancer: A Pilot Study. Conference Abstract. This study was conducted by Mayo Clinic in Rochester, MN (CLS-20587117) and registered at Mayo Clinic (https://www.mayo.edu/research/clinical-trials/cls-20587117) and ClinicalTrials.gov (NCT07216274).

This prospective pilot study evaluated the effectiveness of QTscans compared with MRI as a supplemental screening tool for patients with a high risk of breast cancer. The study enrolled 26 women with an elevated lifetime risk of breast cancer (>20%) from July to October, 2025. All patients underwent a bilateral breast MRI and QTscan, where the QTscan was performed within 30 days of the MRI. Images of both modalities were independently interpreted by four breast radiologists with 2-24 years of experience. For each finding, the radiologists recorded imaging characteristics, size, and location and assigned a Breast Imaging Reporting and Data System (BI-RADS) score. Agreement between paired MRI and QTscan BI-RADS scores was evaluated for the ordinal (BI-RADS 1-5) and the binary categories of negative (BI-RADS 1-2) or positive (BI-RADS 3-5).

In this study, the radiologists recorded up to three imaging findings per breast with a total of 104 breast images analyzed for the entire cohort of 26 patients. Across both imaging modalities, 71/104 breast images had no findings, 30/104 had one finding, and 3/104 had two findings. The study found exact BI-RADS agreement between QTscan and MRI in 34/52 breasts (65%), with a weighted Cohen's kappa of 0.28 (-0.093, 0.594). It observed binary agreement in 47/52 breasts (90%) with unweighted Cohen's kappa of 0.23 (-0.083, 0.781). One BI-RADS 4 MRI finding with benign pathology on biopsy was classified as BI-RADS 3 on a QTscan. In summary, this pilot study demonstrated that the high absolute agreement between MRI and QTscans, suggesting their comparable effectiveness in identifying positive findings.

**Government Regulation**

Our existing product, the QT Breast Scanner, products under development, and our operations are subject to extensive regulation by the FDA, and other federal and state authorities in the U.S., as well as comparable authorities in foreign jurisdictions. Our products do not emit radiation, but are subject to regulation as medical devices in the U.S. under the FDCA and as implemented and enforced by the FDA, and under comparable regulatory schemes in foreign jurisdictions.

***FDA Regulation of Medical Devices***

The FDA regulates the development, design, non-clinical and clinical research, manufacturing, safety, efficacy, labeling, packaging, storage, installation, servicing, recordkeeping, premarket clearance or approval, adverse event reporting, advertising, promotion, marketing and distribution, and import and export of medical devices to ensure that medical devices distributed within the U.S. are safe and effective for their intended uses and otherwise meet the requirements of the FDCA.

*FDA Premarket Clearance and Approval Requirements*

Subject to certain exceptions, each medical device commercially distributed in the U.S. requires either FDA clearance of a 510(k) premarket notification, or approval of a pre-market approval application ("***PMA***"). Under the FDCA, medical

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

devices are classified into one of three classes-Class I, Class II or Class III-depending on the degree of risk associated with each medical device and the extent of manufacturer and regulatory control needed to ensure its safety and effectiveness. Class I includes devices with the lowest risk to the patient and are those for which safety and effectiveness can be assured by adherence to the FDA's General Controls for medical devices, which include compliance with the applicable portions of Quality System Regulation ("***QSR***"), facility registration and product listing, reporting of adverse medical events and truthful and non-misleading labeling, advertising and promotional materials. Class II devices are subject to the FDA's General Controls, and special controls as deemed necessary by the FDA to ensure the safety and effectiveness of the device. These special controls can include performance standards, post-market surveillance, patient registries and FDA guidance documents.

While most Class I devices are exempt from the 510(k) premarket notification requirement, manufacturers of most Class II devices are required to submit to the FDA a premarket notification under Section 510(k) of the FDCA requesting permission to commercially distribute the device. The FDA's permission to commercially distribute a device subject to a 510(k) premarket notification is generally known as 510(k) clearance. Devices deemed by the FDA to pose the greatest risks, such as life sustaining, life supporting or some implantable devices, or devices that have a new intended use, or use advanced technology that is not substantially equivalent to that of a legally marketed device, are placed in Class III, requiring approval of a PMA. Some pre-amendment devices are unclassified, but are subject to the FDA's premarket notification and clearance process in order to be commercially distributed.

*510(k) Clearance Marketing Pathway*

The current QT Breast Scanner is a Class II device, and the Company expects products under development such as the QT Infant Scanner and the QT Orthopedic Scanner will also be Class II devices subject to premarket notification and clearance under section 510(k) of the FDCA. To obtain 510(k) clearance, the Company must submit to the FDA a premarket notification submission demonstrating that the proposed device is "substantially equivalent" to a predicate device already on the market. A predicate device is a legally marketed device that is not subject to premarket approval, i.e., a device that was legally marketed prior to May 28, 1976 (pre-amendments device), and for which a PMA is not required, a device that has been reclassified from Class III to Class II or I, or a device that was found substantially equivalent through the 510(k) process. The FDA's 510(k) clearance process usually takes from three to twelve months, but often takes longer. The FDA may require additional information, including clinical data, to make a determination regarding substantial equivalence. In addition, the FDA collects user fees for certain medical device submissions and annual fees and for medical device establishments. For fiscal year 2025, the small business user fee for a 510(k) premarket notification application is $9,280. If the FDA agrees that the device is substantially equivalent to a predicate device currently on the market, it will grant 510(k) clearance to commercially market the device. If the FDA determines that the device is "not substantially equivalent" to a previously cleared device, the device is automatically designated as a Class III device. The device sponsor must then fulfill more rigorous PMA requirements, or can request a risk-based classification determination for the device in accordance with the "de novo" process, which is a route to market for novel medical devices that are low to moderate risk and are not substantially equivalent to a predicate device.

After a device receives 510(k) marketing clearance, any modification that could significantly affect its safety or effectiveness, or that would constitute a major change or modification in its intended use, will require a new 510(k) clearance or, depending on the modification, PMA approval or *de novo* reclassification. The FDA requires each manufacturer to determine whether the proposed change requires submission of a 510(k), a *de novo* request or a PMA in the first instance, but the FDA can review any such decision and disagree with a manufacturer's determination. If the FDA disagrees with a manufacturer's determination, the FDA can require the manufacturer to cease marketing and/or request the recall of the modified device until 510(k) marketing clearance or until PMA approval is obtained or a *de novo* request is granted. Also, in these circumstances, the manufacturer may be subject to significant regulatory fines or penalties.

Over the last several years, the FDA has proposed reforms to its 510(k) clearance process, and such proposals could include increased requirements for clinical data and a longer review period, or could make it more difficult for manufacturers to utilize the 510(k) clearance process for their products. For example, in November 2018, the FDA officials announced forthcoming steps that the FDA intends to take to modernize the premarket notification pathway under Section 510(k) of the FDCA. Among other things, the FDA announced that it planned to develop proposals to drive manufacturers utilizing the 510(k) pathway toward the use of newer predicates. These proposals included plans to potentially sunset certain older devices that were used as predicates under the 510(k) clearance pathway, and to potentially publish a list of devices that have been cleared on the basis of demonstrated substantial equivalence to predicate devices that are more than 10 years old. In May 2019, the FDA solicited public feedback on these proposals. The FDA requested public feedback on whether it should consider certain actions that might require new authority, such as whether to sunset certain older devices

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

that were used as predicates under the 510(k) clearance pathway. These proposals have not yet been finalized or adopted, and the FDA may work with Congress to implement such proposals through legislation.

More recently, in September 2019, the FDA finalized guidance describing an optional "safety and performance based" premarket review pathway for manufacturers of "certain, well-understood device types" to demonstrate substantial equivalence under the 510(k) clearance pathway by showing that such device meets objective safety and performance criteria established by the FDA, thereby obviating the need for manufacturers to compare the safety and performance of their medical devices to specific predicate devices in the clearance process. The FDA intends to develop and maintain a list of device types appropriate for the "safety and performance based" pathway and will continue to develop product-specific guidance documents that identify the performance criteria for each such device type, as well as the testing methods recommended in the guidance documents, where feasible.

*Post-Market Regulation*

After a device is cleared or approved for marketing, numerous and pervasive regulatory requirements continue to apply. These include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• establishment registration and device listing with the FDA;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• QSR requirements, which require manufacturers, including third-party manufacturers, to follow stringent design, testing, control, documentation and other quality assurance procedures during all aspects of the design and manufacturing process;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• labeling regulations and FDA prohibitions against the promotion of investigational products, or the promotion of "off-label" uses of cleared or approved products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• requirements related to promotional activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• clearance or approval of product modifications to 510(k)-cleared devices that could significantly affect safety or effectiveness or that would constitute a major change in intended use of one of our cleared devices, or approval of certain modifications to PMA-approved devices;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• medical device reporting regulations, which require that a manufacturer report to the FDA if a device it markets may have caused or contributed to a death or serious injury, or has malfunctioned and the device or a similar device that it markets would be likely to cause or contribute to a death or serious injury, if the malfunction were to recur;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• correction, removal and recall reporting regulations, which require that manufacturers report to the FDA field corrections and product recalls or removals if undertaken to reduce a risk to health posed by the device or to remedy a violation of the FDCA that may present a risk to health;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the FDA's recall authority, whereby the agency can order device manufacturers to recall from the market a product that is in violation of governing laws and regulations; and post-market surveillance activities and regulations, which apply when deemed by the FDA to be necessary to protect the public health or to provide additional safety and effectiveness data for the device.

The Company's manufacturing processes are required to comply with the applicable portions of the QSR, which cover the methods and the facilities and controls for the design, manufacture, testing, production, processes, controls, quality assurance, labeling, packaging, distribution, installation and servicing of finished devices intended for human use. The QSR also requires, among other things, maintenance of a device master file, device history file and complaint files. As a manufacturer, the Company will be subject to periodic scheduled or unscheduled inspections by the FDA. The Company's failure to maintain compliance with the QSR requirements could result in the shut-down of, or restrictions on, the Company's manufacturing operations and the recall or seizure of its products, which would have a material adverse effect on the Company's business. The discovery of previously unknown problems with any of the Company's products, including unanticipated adverse events or adverse events of increasing severity or frequency, whether resulting from the use of the device within the scope of its clearance or off-label by a physician in the practice of medicine, could result in restrictions on the device, including the removal of the product from the market or voluntary or mandatory device recalls.

The FDA has broad regulatory compliance and enforcement powers. If the FDA determines that we failed to comply with applicable regulatory requirements, it can take a variety of compliance or enforcement actions, which may result in any of the following sanctions:

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• warning letters, untitled letters, fines, injunctions, consent decrees and civil penalties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• recalls, withdrawals or administrative detention or seizure of our products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• operating restrictions or partial suspension or total shutdown of production;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• withdrawing 510(k) clearances or PMA approvals that have already been granted;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• refusal to grant export approvals for our products; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• criminal prosecution.

***Healthcare Regulatory Laws***

Within the U.S., the Company's products and its customers will be subject to extensive regulation by a wide range of federal and state agencies that govern business practices in the medical device industry. These laws include federal and state anti-kickback, fraud and abuse, false claims, transparency and anti-corruption statutes and regulations. Internationally, other governments also impose regulations in connection with their healthcare reimbursement programs and the delivery of healthcare items and services.

U.S. federal healthcare fraud and abuse laws will generally apply to the Company's activities, among other reasons because the Company expects that its products will be covered under federal healthcare programs such as Medicare and Medicaid. The U.S. federal healthcare program Anti-Kickback Statute (the "***Anti-Kickback Statute***") is particularly relevant because of its broad applicability. Specifically, the Anti-Kickback Statute prohibits persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in exchange for, or to induce, either the referral of an individual, or the furnishing, arranging for or recommending a good or service for which payment may be made in whole or part under federal healthcare programs, such as the Medicare and Medicaid programs. Almost any financial interaction with a healthcare provider, patient or customer will implicate the Anti-Kickback Statute. Statutory exceptions and regulatory safe harbors protect certain interactions if specific requirements are met. However, only those interactions that represent fair market value exchanges generally are protected by a safe harbor or exception. The government can exercise enforcement discretion in taking action against unprotected activities. Further, a person or entity does not need to have actual knowledge of the Anti-Kickback Statute or specific intent to violate it in order to have committed a violation. In addition, the government may assert that a claim including items or services resulting from a violation of the federal Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the federal False Claims Act or federal civil money penalties statute. Penalties for Anti-Kickback Statute violations may include both criminal penalties such as imprisonment and civil sanctions such as fines, imprisonment and possible exclusion from Medicare, Medicaid and other federal healthcare programs. Exclusion would mean that diagnostic tests using the Company's products would no longer be eligible for reimbursement under federal healthcare programs.

Many states have adopted laws similar to the Anti-Kickback Statute. Some of these state prohibitions apply to referral of patients for healthcare items or services reimbursed by any payor, not only federal healthcare programs. Insurance companies may also bring a private cause of action for treble damages against a manufacturer for a pattern of causing false claims to be filed under the federal Racketeer Influenced and Corrupt Organizations Act.

Another development affecting the healthcare industry is the increased use of the federal Civil False Claims Act and, in particular, actions brought pursuant to the False Claims Act's "whistleblower" or "qui tam" provisions. The False Claims Act imposes liability on any person or entity that, among other things, knowingly presents, or causes to be presented, a false or fraudulent claim for payment by a federal healthcare program. The qui tam provisions of the False Claims Act allow a private individual to bring actions on behalf of the federal government alleging that the defendant has submitted a false claim to the federal government, and to share in any monetary recovery. In recent years, the number of suits brought against healthcare providers by private individuals has increased dramatically. In addition, various states have enacted false claim laws analogous to the Civil False Claims Act, although many of these state laws apply where a claim is submitted to any third-party payor and not merely a federal healthcare program.

The Health Insurance Portability and Accountability Act of 1996 ("HIPAA"), among other things, created two new federal crimes: healthcare fraud and false statements relating to healthcare matters. The HIPAA healthcare fraud statute prohibits, among other things, knowingly and willfully executing, or attempting to execute, a scheme to defraud any healthcare benefit program, including private payors. A violation of this statute is a felony and may result in fines, imprisonment and/or exclusion from government-sponsored programs. The HIPAA false statements statute prohibits, among other things, knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false, fictitious or fraudulent statement or representation in connection with the delivery of or payment for healthcare benefits, items or

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

services. A violation of this statute is a felony and may result in fines and/or imprisonment. Similar to the federal Anti-Kickback Statute, a person or entity does not need to have actual knowledge of the statutes or specific intent to violate them in order to have committed a violation.

Laws and regulations have also been enacted by the federal government and various states to regulate the sales and marketing practices of medical device and pharmaceutical manufacturers. The laws and regulations generally limit financial interactions between manufacturers and healthcare providers, require pharmaceutical and medical device companies to comply with voluntary compliance standards issued by industry associations and the relevant compliance guidance promulgated by the U.S. federal government and/or require disclosure to the government and/or public of financial interactions (so-called "sunshine laws"). Many of these laws and regulations contain ambiguous requirements or require administrative guidance for implementation. Manufacturers must adopt reasonable interpretations of requirements if there is ambiguity and those interpretations could be challenged. Given the lack of clarity in laws and their implementation, the Company's activities could be subject to the penalty provisions of the pertinent federal and state laws and regulations.

*Healthcare Reform*

In the U.S. and certain foreign jurisdictions, there have been, and the Company expects there will continue to be, a number of legislative and regulatory changes to the healthcare system. In March 2010, the Patient Protection and Affordable Care Act, and the Health Care and Education Reconciliation Act of 2010 (collectively, the "***ACA***") was signed into law and substantially changed the way healthcare is financed by both governmental and private insurers in the United States. The ACA contains a number of provisions, including those governing enrollment in federal healthcare programs, reimbursement adjustments and fraud and abuse changes. Additionally, the ACA imposed, among other things, a new federal excise tax on the sale of certain medical devices, which, through a series of legislative amendments, was suspended, effective January 1, 2016, and subsequently repealed altogether on December 20, 2019, provided incentives to programs that increase the federal government's comparative effectiveness research and implemented payment system reforms including a national pilot program on payment bundling to encourage hospitals, physicians and other providers to improve the coordination, quality and efficiency of certain healthcare services through bundled payment models. Since its enactment, there have been judicial and Congressional challenges to certain aspects of the ACA, and the Company expects there will be additional challenges and amendments to the ACA in the future.

Since its enactment, there have been judicial and Congressional challenges to certain aspects of the ACA, and the Company expects there will be additional challenges and amendments to the ACA in the future. By way of example, in 2017, Congress enacted the Tax Cuts and Jobs Act (the "***TCJA***"), which eliminated the tax-based shared responsibility payment imposed by the ACA on certain individuals who fail to maintain qualifying health coverage for all or part of a year that is commonly referred to as the "individual mandate." On December 14, 2018, a Texas U.S. District Court Judge ruled that the individual mandate is a critical and inseverable feature of the ACA, and therefore, because it was repealed as part of the TCJA, the remaining provisions of the ACA are invalid as well. On December 18, 2019, the U.S. Court of Appeals for the 5th Circuit ruled that the individual mandate was unconstitutional and remanded the case back to the District Court to determine whether the remaining provisions of the ACA are invalid as well. However, the decision of the U.S. Court of Appeals for the 5th Circuit was appealed to the U.S. Supreme Court. On June 17, 2021, the U.S. Supreme Court held that the states that initially commenced the challenge to the ACA didn't have standing to challenge the law, effectively ending this challenge. But it remains possible that future challenges to the ACA may be brought, and it is unclear how any future decisions and other efforts to repeal and replace the ACA will impact the ACA.

Other legislative changes have been proposed and adopted in the United States since the ACA was enacted, including aggregate reductions of Medicare payments to providers of 2% per fiscal year and reduced payments to several types of Medicare providers. The Company believes the overall escalating cost of medical products and services being paid for by the government and private health insurance has led to, and will continue to lead to, increased pressures on the healthcare and medical device industry to reduce the costs of products and services.

*Data Privacy and Security*

Medical device companies may be subject to U.S. federal and state and foreign health information privacy, security and data breach notification laws, which may govern the collection, use, disclosure and protection of health-related and other personal information. In the U.S., HIPAA imposes privacy, security and breach reporting obligations with respect to individually identifiable health information upon "covered entities" (health plans, health care clearinghouses and certain health care providers), and their respective business associates, individuals or entities that create, receive, maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity. HIPAA and its respective implementing regulations, including the final omnibus rule published on January 25, 2013, imposes

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

specified requirements relating to the privacy, security and transmission of individually identifiable health information. HIPAA mandates the reporting of certain breaches of health information to HHS, affected individuals and if the breach is large enough, the media. Entities that are found to be in violation of HIPAA as the result of a breach of unsecured protected health information ("***PHI***"), a complaint about privacy practices or an audit by HHS, may be subject to significant civil, criminal and administrative fines and penalties and/or additional reporting and oversight obligations if required to enter into a resolution agreement and corrective action plan with HHS to settle allegations of HIPAA non-compliance. The Health Information Technology and Clinical Health Act also increased the civil and criminal penalties that may be imposed against covered entities, business associates and possibly other persons, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney's fees and costs associated with pursuing federal civil actions.

Even when HIPAA does not apply, according to the Federal Trade Commission (the "***FTC***"), failing to take appropriate steps to keep consumers' personal information secure constitutes unfair acts or practices in or affecting commerce in violation of Section 5(a) of the Federal Trade Commission Act, 15 U.S.C § 45(a). The FTC expects a company's data security measures to be reasonable and appropriate in light of the sensitivity and volume of consumer information it holds, the size and complexity of its business, and the cost of available tools to improve security and reduce vulnerabilities. Individually identifiable health information is considered sensitive data that merits stronger safeguards. The FTC's guidance for appropriately securing consumers' personal information is similar to what is required by the HIPAA Security Rule.

In addition, certain state and non-U.S. laws, such as the European Union's General Data Protection Regulation (2016/679) ("***GDPR***"), govern the privacy and security of health information in certain circumstances, some of which are more stringent than HIPAA and many of which differ from each other in significant ways and may not have the same effect, thus complicating compliance efforts. Further, "business associates," defined as independent contractors or agents of covered entities that create, receive, maintain or transmit protected health information in connection with providing a service for or on behalf of a covered entity, are also subject to certain HIPAA privacy and security standards. Failure to comply with these laws, where applicable, can result in the imposition of significant civil and/or criminal penalties and private litigation. For example, California recently enacted legislation, the California Consumer Privacy Act ("***CCPA***"), which went into effect January 1, 2020. The CCPA, among other things, creates new data privacy obligations for covered companies and provides new privacy rights to California residents, including the right to opt out of certain disclosures of their information. The CCPA also creates a private right of action with statutory damages for certain data breaches, thereby potentially increasing risks associated with a data breach. Although the law includes limited exceptions, including for PHI maintained by a covered entity or business associate, it may regulate or impact the Company's expected processing of personal information depending on the context. In Europe, the GDPR went into effect in May 2018 and introduces strict requirements for processing the personal data of European Union data subjects. Companies that must comply with the GDPR face increased compliance obligations and risk, including more robust regulatory enforcement of data protection requirements and potential fines for noncompliance of up to €20 million or 4% of the annual global revenues of the noncompliant company, whichever is greater. The State of Israel has also implemented data protection laws and regulations, including the Israeli Protection of Privacy Law of 1981.

***Foreign Regulation***

As the Company plans to market and deploy the QT Breast Scanner and products under development broadly across the globe, the Company will be subject to regulations applicable to medical and radiation-emitting devices in the jurisdictions in which the Company operates, which regulations vary among countries. While some countries' regulations may not impose barriers to marketing and selling the Company's products or only require certain notification, others may require that the Company obtains the clearance, registration or approval of a specified regulatory body. The process for obtaining such clearance, registration or approvals may involve additional testing and time. Furthermore, complying with foreign regulatory requirements can be expensive and time-consuming, and the Company will need to seek for regulatory clearances or approvals in each country in which the Company plans to market the Company's products. In addition, depending on the country, if the Company modifies the Company's products, the Company may need to apply for additional regulatory clearances or approvals before the Company is permitted to sell the modified product. Also, for maintaining the Company's authorizations in a particular country, the Company will need to continue meeting quality and safety standards required in such country. The Company may seek additional regulatory approvals outside of the U.S. but as of the date of this registration statement/prospectus, the Company does not have sufficient information to determine when, if ever, the Company will receive regulatory approval from any other jurisdictions.

Following entry into the Gulf Medical Distribution Agreement, the Company has also begun the regulatory approval process with the Saudi FDA ("***SFDA***"), and is doing the same with the United Arab Emirates FDA ("***MOHAP***"), which

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

has been given in March 2026. The Company also intends to do the same in the European Union in 2026 to obtain a CE Mark.

Finally, while regulatory clearance or approval by the FDA does not ensure registration, clearance or approval by regulatory authorities in other countries, registration or regulatory clearance or approval in one country, or denial thereof, may have effects on the regulatory process in others.

*of operations, and growth prospects. In such an event, the market price of our common stock could decline, and you may lose all or part of your investment. The following discussion should be read in conjunction with the respective consolidated financial statements of the Company, and the notes to the consolidated financial statements included therein.* 

**Risks Related to Our Business, Financial Condition, and Need for Additional Capital** 

***We are a development-stage company with limited operating history and significant losses since inception which may make it difficult to evaluate prospects for our future viability and predict our future performance. We may never be able to effectuate our business plan or achieve any meaningful revenue or reach profitability.***

We have a limited operating history and only a preliminary and unproven business plan upon which investors may evaluate our prospects. We have demonstrated the commercial viability of our breast imaging platform at scales of tens of scanners but not yet demonstrated the commercial viability on larger scales. The QT Breast Scanner is deployed at facilities in the United States and abroad. Even if we are able to do so, we may not be able to manufacture the QT Breast Scanner device at the costs needed to support our business model. Even if we are able to commercialize some of our products or product candidates, there can be no assurance that we will generate significant revenues or ever achieve profitability. We expect to continue to incur significant sales and marketing, research and development, regulatory and other expenses as we expand our marketing efforts to increase adoption of our products, expand existing relationships, obtain regulatory approvals for our product candidates, conduct clinical studies on our existing and planned product candidates and develop new product candidates or add new features to our existing products. There is no assurance that our distribution partners will succeed in selling and servicing devices in sufficient volumes to help the company meet its business plan, revenue objectives or profitability.

Furthermore, even if our technology and product become commercially viable and deployed at scale, we may not generate sufficient revenue necessary to support our business. We may never successfully stimulate market interest in our QT Breast Scanner in the near-to-mid-term at any level or at all, which may cause our business to fail. The medical imaging industry is also highly competitive, and our technology, products, services or business models may not achieve widespread market acceptance. If we are unable to address any issues mentioned above, or encounter other problems, expenses, difficulties, complications, and delays in connection with the starting and expansion of our business, our entire business may fail, in which case you may lose your entire investment.

We have a history of net losses and negative cash flow from operations since inception and we expect such losses and negative cash flows from operations to continue in the foreseeable future. As of December 31, 2025 and 2024, we had an accumulated deficit of approximately $53.0 million and $31.9 million, respectively. For the years ended December 31, 2025 and 2024, we incurred net losses attributable to the Company of approximately $21.1 million and $9.0 million, respectively. For the years ended December 31, 2025 and 2024, we used cash in operations of $9.0 million and $10.0 million, respectively. We anticipate our losses will continue to increase from current levels because we expect to incur additional costs related to developing our business, including research and development costs, manufacturing costs, employee-related costs, costs of complying with government regulations, intellectual property development and prosecution costs, marketing and promotion costs, capital expenditures, general and administrative expenses, and costs associated with operating as a public company.

Our ability to generate revenue from our operations and ultimately achieve profitability will depend on factors including but not limited to whether we can complete the development and commercialization of our QT Breast Scanner breast imaging technology and our future products, whether we can manufacture the QT Breast Scanner and future products on a commercial scale in such amounts and at such costs as we anticipate, and whether we can achieve market acceptance of our products, services and business models. The net losses that we incur may fluctuate significantly from period to period. As a result of these increased expenditures, we will need to generate significant additional revenue in order to offset our operating expenses and achieve and sustain profitability. Accordingly, we may not achieve or maintain profitability, and we may continue to incur significant losses in the future. Even if we achieve profitability, we cannot be sure that we will remain profitable for any substantial period of time. If we do not achieve or sustain profitability, it will be more difficult for us to finance our business and accomplish our strategic objectives, either of which would have a material adverse effect on our business, financial condition, results of operations and prospects and may cause the market price of the common stock to decline.

***We may not be able to successfully execute our business model.***

We are a company with limited operating history and we may not have the necessary resources, expertise and experience to successfully execute our business model on a global scale, such as obtaining the necessary approvals or clearances from the regulatory agencies of our target markets. Our ability to execute our model is dependent on a number of factors, including the ability of our senior management team to execute our model, our ability to incentivize, train and support international distribution partners in different geographic regions, our ability to begin or maintain our pace of product development,

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

manufacturing and commercialization, our ability to meet the changing needs of the medical imaging market, and the ability of our employees to perform at a high-level. If we are unable to execute our model, or if our model does not drive the growth that we anticipate, or if our market opportunity is not as large as we have estimated, it could adversely affect our business and our prospects.

***We have a limited operating history. If we successfully commercially launch the QT Breast Scanner, products under development that are cleared by the FDA and other regulatory agencies, and they do not achieve widespread market acceptance, we will not be able to generate the revenue necessary to support our business.***

We have a limited operating history of two years as a public company, and limited market adoption our breast-imaging technology, the QT Breast Scanner or any other product using our 3D transmission ultrasound technology. We may fail to generate significant interest in the QT Breast Scanner, or other imaging products using our technology. These and other factors, including the following, may affect the rate and level of market acceptance:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• effectiveness of the sales and marketing efforts of us, and our distribution partners;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• perception by medical professionals and patients of the convenience, safety, efficiency and benefits of the QT Breast Scanner or products under development using our technology, compared to competing methods of medical imaging;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• opposition from certain industry leaders, which may limit our ability to promote the QT Breast Scanner or products under development that are cleared by the FDA and other regulatory agencies, and to penetrate into the medical imaging market in the U.S. or other geographical areas;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the level of commitment and support that we receive from our partners, such as cloud storage providers, as well as medical professionals such as radiologists;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• coverage determinations and reimbursement levels of third-party payors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the changing and volatile U.S. and global economic environments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• timing of market introduction of competing products, and the sales and marketing initiatives of such products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• press and blog coverage, social media coverage, and other publicity and public relations factors by others; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• lack of financing or other resources to successfully develop and commercialize our technology and implement our business plan.

The technology underlying the QT Breast Scanner may be perceived as inferior or inaccurate and patients may be unwilling to undergo medical screening using the QT Breast Scanner or other products under development using our technology. Moreover, patients and medical professionals may be unwilling to depart from the current medical imaging technology. Medical professionals tend to be slow to change their medical diagnostic practices because of perceived liability risks arising from the use of new technology or products, and they may not recommend medical imaging using the QT Breast Scanner or other products under development using our technology until there is long-term clinical evidence to convince them to alter or modify their existing imaging methods. Our efforts to educate patients, radiologists and other members of the medical community on the benefits of our products require significant resources and may not be successful. Our efforts to educate the marketplace may require more resources than are required by conventional technologies marketed by our competitors. In the event that the QT Breast Scanner or other products under development using our technology are the subject of guidelines, clinical studies or scientific publications that are unfavorable or damaging, or otherwise call into question their benefits, we may have difficulty in convincing market participants to adopt our products. In addition, payors may not adopt or reimburse the use of the QT Breast Scanner or products under development in the near term or at all. Among other things, we need radiologists or other medical professionals to be trained to read the images that the QT Breast Scanner generates, and there are a limited number of such professionals currently trained and even fewer who are capable of providing such training. If we are unable to have a sufficient number of trained readers, then clinics will be less likely to purchase QT Breast Scanners as they will have difficulty using them to provide services to patients.

If we are unable to achieve or maintain an adequate level of market acceptance, we may not generate significant revenue or become profitable and our business, financial condition, results of operations and prospects would be significantly harmed.

***The success of our business model is subject to numerous risks and uncertainties.***

We expect sales to hospitals, academic medical centers, cancer centers, and imaging centers to be our primary end customers. We may not be successful in achieving these goals for various reasons, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the process of manufacturing and deploying the QT Breast Scanner and our products under development is a complex, multi-step process that depends on factors outside our control, and could cause us to expend significant time and resources prior to earning associated revenues;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the manufacturing cost of the QT Breast Scanner and our products under development may be higher than we expect, may increase significantly, or may increase at a higher rate than anticipated;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the manufacturing of the QT Breast Scanner and our future products may take longer than we expected, and we may have insufficient manufacturing capacity and experience delays in manufacturing and deployment, which would have a negative impact on the timing of our revenues;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• deployment and full utilization of the QT Breast Scanner may not be achieved if insurance and other reimbursements and patient co-pays are not sufficient to defray costs incurred in providing and interpreting scans by hospital imaging centers, cancer centers or other women's health-care centers that purchase our devices and services, and we may not be able to sustain these relationships unless our devices can be profitable to these providers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a QT Breast Scanner device may perform fewer scans per day than our estimates due to a number of factors, including low market acceptance rate, technical failures and downtime, service disruptions, outages or other performance problems, which would have a negative impact on our revenues and our ability to recover costs; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our customers may not be able to find or retain a sufficient number of radiologists to review the images generated by the QT Breast Scanner device especially as we deploy additional systems and the volume of scans increases.

Any of the above factors may negatively affect the successful commercialization and implementation of our business model, causing our business to fail.

***We may need to raise additional capital, which may not be available on favorable terms, if at all, and which may cause dilution to stockholders, restrict our operations or adversely affect our ability to operate our business.***

Our ability to raise additional capital may be significantly affected by general market conditions, the market price of our common stock, our financial condition, uncertainty about the future commercial success of our products, regulatory developments, the status and scope of our intellectual property, any ongoing arbitration or litigation, our compliance with applicable laws and regulations and other factors, many of which are outside our control. We cannot be certain that we will be able to obtain additional financing on favorable terms or at all. If we are unable to obtain needed financing on acceptable terms, or otherwise, we may not be able to implement our business plan, which could have a material adverse effect on our business, financial condition and results of operations, including a decline in the trading price of our common stock. Any additional equity financings could result in additional dilution to our then existing stockholders. In addition, we may enter into additional financings that restrict our operations or adversely affect our ability to operate our business and, if we issue equity, debt or other securities to raise additional capital or restructure or refinance our existing indebtedness, the new equity, debt or other securities may have rights, preferences and privileges senior to those of our existing stockholders.

***Our ability to generate the amount of cash needed to pay interest and principal on any indebtedness and our ability to refinance all or a portion of our indebtedness or obtain additional financing depends on many factors beyond our control.***

Our ability to make scheduled payments on, or to refinance our obligations under, any indebtedness depends on our financial and operating performance and prevailing economic and competitive conditions. Certain of these financial and business factors, many of which may be beyond our control, are described above.

If our cash flows and capital resources are insufficient to fund our debt service obligations, we may be forced to reduce or delay capital expenditures, sell assets, raise additional equity capital, or restructure our debt. However, there is no assurance that such alternative measures may be successful or permitted under the agreements governing our indebtedness and, as a result, we may not be able to meet our scheduled debt service obligations. Even if successful, actions taken to improve short-term liquidity to meet our debt service and other obligations could harm our long-term business prospects, financial condition, and results of operations.

We cannot guarantee that we will be able to refinance our indebtedness or obtain additional financing on satisfactory terms or at all, including due to existing guarantees on our assets or our level of indebtedness and the debt incurrence restrictions imposed by the agreements governing our indebtedness. Further, the cost and availability of credit are subject to changes in the economic and business environment. If conditions in major credit markets deteriorate, our ability to refinance our indebtedness or obtain additional financing on satisfactory terms, or at all, may be negatively affected.

***Our debt agreements contain restrictions that may limit our flexibility in operating our business.***

The loan agreement with Lynrock Lake Master Fund LP ("***Lynrock Lake***") and related documents contain, and instruments governing any future indebtedness of ours would likely contain, a number of covenants that will impose significant operating and financial restrictions on us, including restrictions on our ability to, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• create liens on certain assets;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• incur additional debt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• consolidate, merge, sell or otherwise dispose of all or substantially all of our assets; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• sell certain assets.

Any of these restrictions could limit our ability to plan for or react to market conditions and could otherwise restrict corporate activities. Any failure to comply with these covenants could result in a default under our secured credit facility or instruments governing any future indebtedness of ours. Additionally, our credit facility is secured by substantially all of our assets. Upon a default, unless waived, the lenders under our secured credit facility could elect to terminate their commitments, cease making further loans, foreclose on our assets pledged to such lenders to secure our obligations under our credit agreement and force us into bankruptcy or liquidation. In addition, a default under our secured credit facility could trigger a cross default under agreements governing any future indebtedness. Our results of operations may not be sufficient to service our indebtedness and to fund our other expenditures, and we may not be able to obtain financing to meet these requirements. In February 2026, we obtained waivers from Lynrock Lake in connection with non-compliance to certain of our debt covenants related to information reporting during the first three quarters of 2025. If we experience a default under our secured credit facility or instruments governing our future indebtedness, our business, financial condition, and results of operations may be adversely impacted.

***We are highly dependent on the successful development, marketing and sale of our breast imaging device and on other products and product candidates which are still in the development stage.***

Our breast imaging technology is the basis of our business. The QT Breast Scanner is currently deployed in a limited number of cancer and other health centers, and is undergoing field testing and broad acceptance is uncertain. As a result, the success of our business plan is highly dependent on acceptance of our products, and on our ability to develop, manufacture and commercialize the technology and related products and services and our failure to do so could cause our business to fail. As part of our effort to build the sales and marketing capabilities of the Company, on May 31, 2023, the Company entered into the NXC Sales Agent Agreement, pursuant to which the Company appointed NXC as the non-exclusive agent for the sale of the Company products and services in non-exclusive territories: the U.S., U.S. territories, and U.S. Department of Defense installations. Subsequently, effective June 10, 2024, we replaced the NXC Sales Agent Agreement with the NXC Distribution Agreement, and since then, on December 11, 2024, we and NXC entered into the Amended NXC Distribution Agreement, which we further amended on March 28, 2025. Under the terms of the Amended NXC Distribution Agreement, NXC shall provide us with a forecast of the anticipated purchases of QT Breast Scanners during the subsequent twelve month period. The Amended NXC Distribution Agreement further provides that the forecast for 2026 shall be no less than the MOQs set forth in an exhibit to the Amended NXC Distribution Agreement, by quarter and by year. Furthermore, all purchase orders from NXC shall be for no less than the MOQs, which NXC must order on the quarterly and annual basis as set forth in an exhibit to the Amended NXC Distribution Agreement.

Successful commercialization of medical imaging devices is a complex and uncertain process, dependent on the efforts of management, manufacturers, local operators, integrators, medical professionals, third-party payors, as well as general economic conditions, among other factors. Any factor that adversely impacts the development and commercialization of our imaging technology or related products and services, including the QT Breast Scanner, will have a negative impact on our business, financial condition, results of operations and prospects. Some potential factors that could adversely impact the development and commercialization of our imaging technology or related products and services include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our inability to achieve sufficient market acceptance by hospitals and clinics, providers of medical imaging services, medical professionals such as radiologists, third-party payors, and others in the medical community;

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our inability to compete with existing medical imaging technology companies with ultrasound, mammography and MRI systems, who have well entrenched market-share worldwide and significantly more resources than we do;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our inability to hire, train and retain qualified sales and marketing personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our inability to establish, maintain and expand our sales, marketing and distribution networks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our inability to obtain and/or maintain necessary regulatory approvals; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our inability to effectively protect our intellectual property.

Our inability to successfully obtain additional clearances or approval from the FDA and other regulatory agencies worldwide, and commercialize the QT Breast Scanner and related products and services, and/or successfully develop, secure clearances and approvals, and commercialize additional products or any enhancements to the products which we may develop would have a material adverse effect on our business, financial condition, results of operations and prospects.

***Products utilizing our technology may need to be approved or cleared by the FDA and similar regulatory agencies worldwide. We may not receive additional clearances and approvals from the FDA for the QT Breast Scanner, or may be delayed in receiving the necessary approval or clearance for our future products, which would adversely affect business, financial condition, results of operations and prospects.***

On October 31, 2018, the FDA granted the Company's Breakthrough Device designation request (Q181785) for the QT Breast Scanner. Unlike traditional breast imaging modalities, the QT Breast Scanner has no radiation, no injections, and no compression, potentially offering new opportunities for earlier and more frequent screening for young women at high risk for breast cancer who have no available FDA-cleared screening options. The Company has the following regulatory clearances:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• "The QT Breast Scanner is for use as an ultrasonic imaging system to provide reflection-mode and transmission-mode images of a patient's breast. The QT Breast Scanner software also calculates the breast fibroglandular volume and total breast volume. The device is not intended to be used as a replacement for screening mammography"—FDA 510(k) K162372 and K220933*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*• "The QT Breast Scanner Model 2000A satisfies the requirements of the Certification Mark of the ECM [CE Mark Certification of the European Union]—No. 0P210730.QTUTQ02"*

The Company has initiated engagement with the FDA to determine the most appropriate regulatory pathway for its premarket submission and to align on the clinical studies necessary to support such submission. The regulatory review process is inherently iterative, and the FDA may provide additional feedback requiring modifications or further evidence in response to the Company's initial submission. There can be no assurance that the Company will obtain the necessary regulatory clearances or approvals in a timely or cost-effective manner, or at all. The process of seeking FDA clearance or approval is resource-intensive, time-consuming, and subject to significant uncertainty. Delays, unexpected costs, or failure to obtain such regulatory authorizations could materially and adversely affect the Company's ability to commercialize its technology and generate revenue. Furthermore, even if regulatory clearance or approval is obtained, the Company's products will remain subject to extensive post-market regulatory requirements, including compliance with quality system regulations, post-market surveillance, and reporting obligations. Any failure to comply with these requirements, or the identification of previously unknown issues related to the approved product, manufacturing processes, or manufacturers, could result in administrative or judicial enforcement actions by regulatory authorities, including but not limited to warning letters, fines, injunctions, product recalls, market withdrawal, or civil and criminal penalties. Even if the products containing our technology receive the required regulatory clearance or approval, such products will remain subject to extensive regulatory requirements. If we fail to comply with the regulatory requirements of the FDA and other applicable U.S. and foreign regulatory authorities (as described below), or previously unknown problems with any approved commercial products, manufacturers or manufacturing processes are discovered, we could be subject to administrative or judicially imposed sanctions. Even if we obtain FDA approval of our product candidates, or new indications for our products, market acceptance of our products in the healthcare community, including physicians, patients and third-party payors will depend on many factors, including, without limitation: our ability to provide incremental clinical and economic data that shows the safety and clinical efficacy and cost-effectiveness of, and patient benefits from, our products and product candidates; whether our products and product candidates are included on insurance coverage plans; the willingness and ability of patients and the healthcare community to adopt new technologies; the pricing and reimbursement of our products relative to other products; and the marketing and distribution support for our products and product candidates.

Following entry into the Gulf Medical Distribution Agreement, the Company has also begun the regulatory approval process with the SFDA, and has done the same with the MOHAP, from which the Company received approval on March 17, 2026. The Company also intends to do the same in the European Union in 2026 to obtain a CE Mark.

In addition, the cost of compliance with new laws or regulations governing our technology or future products could adversely affect our business, financial condition, results of operations and prospects. New laws or regulations may impose restrictions or obligations on us that could force us to redesign our technology or other future products or services, and may impose restrictions that are not possible or practicable to comply with, which could cause our business to fail. See *"—Risks Related to Healthcare Industry Shifts and Government Regulation.*"

***Our industry is highly competitive and is subject to technological change, which may result in new products or solutions that are superior to our technology or other future products we may bring to market from time to time.***

The medical imaging industry is rapidly evolving and subject to intense and increasing competition. To compete successfully and to be able to establish and maintain a competitive position in current and future technologies, we will need to demonstrate the advantages of our technology over well-established alternative solutions, products and technologies, such as HHUS, ABUS, mammography and MRI, as well as newer methods of medical imaging and early detection. We believe that effectively engaging market interest for the QT Breast Scanner can be challenging. To achieve this, we will need to raise or develop financial resources, technical expertise, marketing, distribution or support capabilities and we may not be successful in doing so. Many of our current and potential competitors have substantially greater financial, manufacturing, marketing and technical resources than we do. Larger competitors may have substantially larger sales and marketing operations than we or our partners have or plan to have and may have greater name recognition. This may allow those competitors to spend more time with potential customers and to focus on a larger number of potential customers, which would give them a significant advantage over the sales and marketing team we would use and our distributors in making sales.

Larger competitors may also have broader product lines, which enable them to offer customers bundled purchase contracts and quantity discounts. These competitors may have more experience than we have in research and development, marketing, manufacturing, preclinical testing, conducting clinical studies, obtaining FDA and foreign regulatory approvals and marketing approved products. Our competitors may discover technologies and techniques, or enter into partnerships and collaborations, to develop competing products that are more effective or less costly than our products or the products we may develop. There can be no assurance that other companies will not succeed in developing or marketing devices and products that are more effective than our technology or products or that would render our technology or products obsolete or noncompetitive. Academic institutions, government agencies, and other public and private research organizations may seek patent protection regarding potentially competitive products or technologies and may establish exclusive collaborative or licensing relationships with our competitors. Our competitors may be better equipped than we are to respond to competitive pressures. Competition will likely intensify. To our knowledge at the time of filing this annual report, we are not aware of any technologies approved for primary screening clearance by the FDA except for various types of technology related to X-ray mammography.

***We expect to depend on third parties to manufacture a portion of the QT Breast Scanners that we sell and products under development and to supply certain component parts. Our reliance on third-party manufacturers and suppliers involves certain risks that may result in, among others, increased costs, quality or compliance issues, or failure to timely manufacture the QT Breast Scanner and products under development, any of which could materially harm our business.***

If cleared, we expect to rely on third-party suppliers for the commercial production of the QT Breast Scanner and products under development. Our current ability to successfully produce the QT Breast Scanner is limited and if our attempts at commercialization and deployment are successful, we will need the resources of well-established contract manufacturers to manufacture the QT Breast Scanner and products under development at scale. We have entered into the Canon Manufacturing Agreement with CMSC for the manufacture of the QT Breast Scanner in Japan but production under that agreement has been limited to date. In addition, we are dependent on a number of key suppliers for components and sub-assemblies to be able to successfully manufacture the QT Breast Scanner and products under development in limited quantities, and any disruption in the supply of these components and sub-assemblies will have a material impact on our business. Our dependence on such third-party manufacturers and suppliers involves a number of risks, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• insufficient capacity or delays in meeting our demand;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inadequate manufacturing yields, inferior quality and excessive costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inability to manufacture products that meet the agreed upon specifications;

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inability to obtain an adequate supply of materials;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• trade restrictions and changes in tariffs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inability to comply with the relevant regulatory requirements for the manufacturing process;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limited warranties on products supplied to us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• inability to comply with our contractual obligations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• potential increases in prices; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• increased exposure to potential misappropriation of our intellectual property.

If any of our manufacturers or suppliers breach their agreements, are unable to meet their contractual or quality requirements, or become unwilling to perform for any reason, we may be unable, or may be unable in a timely manner, to locate alternative acceptable manufacturers or suppliers and enter into favorable agreements with them.

In addition, if we are required to change the manufacturer of a critical component of our products, we will be required to verify that the new manufacturer maintains facilities, procedures and operations that comply with our quality and applicable regulatory requirements, which could further impede our ability to manufacture our products in a timely manner. Transitioning to a new supplier could be time-consuming and expensive, may result in interruptions in our operations and product delivery, could affect the performance specifications of our products or could require that we modify the design of those systems. If the change in manufacturer results in a significant change to any product, a new clearance or approval from the FDA or similar international regulatory authorization may be necessary before we implement the change, which could cause substantial delays. The occurrence of any of these events could harm our ability to meet the demand for our products in a timely or cost-effective manner. See "—*Risks Related to Healthcare Industry Shifts and Government Regulation*."

***We may experience development or manufacturing problems and higher costs, or delays that could limit our revenue, if any, or increase our losses.***

Developing manufacturing procedures for new products requires developing specific production processes for those products. Developing such processes could be time consuming, and any unexpected difficulty in doing so could delay the successful commercialization and deployment of the QT Breast Scanner and products under development. Moreover, difficulties associated with adapting our technology and product design to the proprietary process technology and design rules of outside manufacturers can lead to reduced yields. Since low yields may result from either design or process technology failures, yield problems may not be effectively determined or resolved until an actual product exists that can be analyzed and tested to identify process sensitivities relating to the design rules that are used. As a result, yield problems may not be identified until well into the production process, and resolution of yield problems may require cooperation between our manufacturers and us. This risk could be compounded by any future offshore location of our manufacturers, increasing the effort and time required to identify, communicate and resolve manufacturing yield problems. Manufacturing defects that we do not discover during the manufacturing or testing process may lead to costly product recalls. These risks may lead to increased costs or delayed product delivery, which would harm our profitability and customer relationships. Furthermore, our, our manufacturers' or our suppliers' production processes and assembly methods may have to change to accommodate any significant, future expansion of our manufacturing capacity, which may increase the manufacturing costs, delay production of our products, reduce our product margin, require supplemental filings with the FDA or other regulatory authorities, any of which may adversely impact our business. If we are unable to keep up with demand for our products by successfully manufacturing and shipping our products in a timely manner, our revenue could be impaired, and market acceptance for our products could be adversely affected.

***We plan to do business globally, including in certain countries where we might have limited resources and would be subject to additional regulatory burdens and other risks and uncertainties.***

We expect to do business globally, including in North America and certain countries in Asia, Europe, Africa and South America. Commercialization of the QT Breast Scanner and products under development in foreign markets, either directly or through third parties, is subject to additional risks and uncertainties, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reimbursement and insurance coverage;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our inability to find agencies, dealers or distributors in specific countries or regions;

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our inability to directly control commercial activities of third parties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limited resources to be deployed to a specific jurisdiction;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the burden of complying with complex and changing regulatory, tax, accounting and legal requirements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• different medical imaging practice and customs in foreign countries affecting acceptance in the marketplace;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• import or export licensing and other requirements that could impair our ability to compete in international markets or subject our company to liability if we violate such laws and regulations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• longer accounts receivable collection times;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• longer lead times for shipping;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• language barriers for technical training;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reduced protection of intellectual property rights in some foreign countries;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• foreign currency exchange rate fluctuations; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• interpretations of contractual provisions governed by foreign laws in the event of a contract dispute.

Sales of the QT Breast Scanner and products under development in foreign markets could also be adversely affected by the imposition of governmental controls, political and economic instability, trade restrictions and changes in tariffs, any of which may adversely affect our business, financial condition, results of operations and prospects.

***We conduct business in the Kingdom of Saudi Arabia and the UAE and military conflicts and geopolitical instability in the Middle East, including U.S. and Israeli military actions against Iran, could disrupt global markets and adversely affect our business and finances.***

Armed conflicts and heightened geopolitical tensions in the Middle East, including ongoing U.S. and Israeli military operations against Iran launched on February 28, 2026, pose risks to the global economy and to our business, particularly as we have distribution arrangements in the Kingdom of Saudi Arabia and the UAE. Iran has retaliated across the Gulf region, including attacks against targets in Qatar, the UAE, Kuwait, Bahrain and the Kingdom of Saudi Arabia. A significant escalation of hostilities in this or other global conflicts may have a material adverse impact on our business. The current military conflict may affect our ability to continue our projects in these regions due to lack of resources, local support, and safety for the workers of our distribution partners. Any disruption to our ability to distribute our products to this region will likely result in an impact on our finances. Furthermore, although the length and impact of the ongoing conflict is in the Middle East is highly unpredictable, it could lead to global market disruptions. The escalation of the conflict in the Middle East and the resulting measures that have been taken, and could be taken in the future, by the United States, NATO (or member countries), the European Union, Israel and its neighboring states and other countries have created global security concerns that could have a lasting impact on regional and global economies. For example, any disruption to the flow of oil through the Strait of Hormuz or other critical shipping lanes, could result in a rapid and sustained increase in global oil and energy prices, which would increase transportation and logistics costs and the cost of petroleum-based production materials. Higher energy and fuel prices would also be disruptive for the global economy and our end user customers. In addition, an escalation of military action in the Middle East could disrupt global shipping routes, increase transit times and freight costs, and create broader supply chain bottlenecks similar to those experienced during prior periods of global disruption. Any macroeconomic deterioration resulting from an escalation in Middle Eastern hostilities could compound the existing challenges facing our business and could have a material adverse effect on our business, financial condition, results of operations, and liquidity.

The extent and duration of the ongoing conflict, resulting sanctions and any related market disruptions are impossible to predict, but could be substantial, particularly if current or new sanctions continue for an extended period of time or if geopolitical tensions result in expanded military operations on a global scale. Any such disruptions may also have the effect of heightening many of the other risks described in this section. If these disruptions or other matters of global

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

concern continue for an extensive period of time, to the extent that we have material operations or assets in a conflict zone, they may be materially adversely affected.

***If in the future we are approved for and are otherwise able to commercialize any of our products or services, but are unable to obtain adequate reimbursement or insurance coverage from third-party payors, we may not be able to generate significant revenue, in which case we may need to obtain additional financing.***

Coding and coverage determinations as well as reimbursement levels and conditions are important to the commercial success of an imaging product or offering. The Company achieved approval of a new Category III CPT code, X579T, for 3D quantitative transmission volumetric ultrasound tomography of the breast from the AMA. This code recognizes the distinct clinical service enabled by the Company's Breast Acoustic CT system's radiation-free, compression-free, 3D breast imaging platform, and becomes effective January 1, 2027. The future availability of insurance coverage and reimbursement for newly approved medical devices is highly uncertain, and our future business will be greatly impacted by the level of reimbursement provided by third-party payors. In the United States, third-party payors decide which imaging products and services they will cover, how much they will pay and whether they will continue reimbursement. Third-party payors may not cover or provide adequate reimbursement for imaging services using the QT Breast Scanner and our products under development, assuming we are able to fully develop and obtain all regulatory approvals and clearances to market it in the United States or other geographies. To date, we have not had any discussions with any third-party payors, including any regulatory agencies administering any government funded healthcare programs, regarding the coding, coverage or reimbursement for imaging services using the QT Breast Scanner or other products under development. Accordingly, unless government and other third-party payors provide coverage and reimbursement for the use of our products and services, patients may not use them, which would cause investors to lose their entire investment. A primary trend in the United States healthcare industry and elsewhere is cost containment. Government authorities and other third-party payors have attempted to control costs by limiting coverage and the amount of reimbursement for particular products and services. Reimbursement may not be available, or continue to be available, for imaging services using the QT Breast Scanner, our SaaS Cloud Platform, other products under development or any other products we may develop in the future. Even if reimbursement is available, such reimbursement may not be adequate. We also will be subject to foreign reimbursement policies in the international markets we expect to enter. Decisions by health insurers or other third-party payors in these markets not to cover, or to discontinue reimbursing, our products could materially and adversely affect our business. If such decisions are made, they could also have a negative impact on our ability to generate revenues, in which case we may need to obtain additional financing.

***Recent changes in the United States related to payment policies for imaging procedures could have a negative impact on the utilization of our imaging services.***

In the United States, over the past several years, the CMS, the federal agency responsible for administering the Medicare program, has implemented numerous changes to payment policies for imaging procedures in both the hospital setting and non-hospital settings, which include physician offices and freestanding imaging facilities. Some of these changes have had a negative impact on utilization of imaging services. Examples of these changes include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limiting payments for imaging services in physician offices and free-standing imaging facility settings based upon rates paid to hospital outpatient departments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• reducing payments for certain imaging procedures when performed together with other imaging procedures in the same family of procedures on the same patient on the same day in the physician office and free-standing imaging facility setting;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• making significant revisions to the methodology for determining the practice expense component of the Medicare payment applicable to the physician office and free-standing imaging facility setting which results in a reduction in payment; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• revising payment policies and reducing payment amounts for imaging procedures performed in the hospital outpatient setting.

We also expect increased regulation and oversight of advanced diagnostic testing. One provision in the Protecting Access to Medicare Act requires CMS to develop AUC that professionals must consult when ordering advanced diagnostic imaging services MRI, CT, nuclear medicine (including position emission tomography) and other advanced diagnostic imaging services that the Secretary of HHS may specify. Beginning in 2020, payment will be made to the furnishing professional for an applicable advanced diagnostic imaging service only if the claim indicates that the ordering professional consulted a qualified clinical decision support mechanism, as identified by HHS, as to whether the ordered service adheres

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

to the applicable AUC. To the extent that these types of changes have the effect of reducing the aggregate number of diagnostic medical imaging procedures performed in the United States, our business, results of operations, financial condition and cash flows would be adversely affected.

***Billing complexities associated with obtaining payment or reimbursement may negatively affect our revenue, cash flow and profitability.***

Billing for imaging services is complex. Payment is provided by individual patients and from a variety of payors, such as commercial insurance carriers, managed care organizations and governmental programs. Each payor typically has different billing requirements, and the billing requirements of many payors have become increasingly stringent.

Among the factors complicating our customers' ability to bill and receive reimbursement from third-party payors are:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• disputes among payors as to which party is responsible for payment;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• disparity in coverage among various payors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• disparity in information and billing requirements among payors; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• incorrect or missing billing information, which is required to be provided by the ordering physician.

In addition, we may be required to seek new billing codes for imaging services using the QT Breast Scanner, and regulatory authorities may not approve the creation of separate codes. Additionally, even if we are successful, these billing codes or the payment amounts associated with such codes may change in the future.

***Any key supplier or distribution agreements that we have established or may establish in the future may not be successful or we may otherwise not realize the anticipated benefits from these agreements. We do not control third parties with whom we have or may have agreements, and we will rely on them to achieve results which may be significant to us. In addition, any current or future agreements may place the development and commercialization of our technology outside our control, may require us to relinquish important rights or may otherwise be on terms unfavorable to us.***

We have entered into certain key distribution agreements, and expect to enter into additional, key supplier and distribution agreements with respect to the research, development, manufacture and commercialization of our technology with different relevant industry participants, including, among others, manufacturers of sub-assemblies and boards, cloud storage providers, distribution partners engaged in selling, marketing and servicing our products in their respective countries, and others as we develop our products including integrators, radiologists, cloud storage and third-party payors. See "*The Company's Business—Key Agreements*." We refer to these third parties that we have agreements with or engage with for future potential agreements as collaborators. For a discussion of the Company's Approved Supplier List and engagements with suppliers, see "*Business — Manufacturing*." Any future potential relationships with collaborators may require us to rely on external consultants, advisors, and experts for assistance in several key functions, including research and development, manufacturing, regulatory and intellectual property. We cannot and will not control these third parties, but we may rely on them to achieve results, which may be significant to us. Relying upon these collaborative arrangements for our technology subjects us to a number of risks, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we may not be able to control the amount and timing of resources that our collaborators may devote to our technology;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• should a collaborator fail to comply with applicable laws, rules or regulations when performing services for us, we could be held liable for such violations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our collaborators may have a shortage of qualified personnel, particularly radiologists who can review the medical images generated by the QT Breast Scanner and products and services under development, especially as we deploy additional devices and new products and the volume of scans increases;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• we may be required to relinquish important rights, such as marketing and distribution rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• business combinations or significant changes in a collaborator's business strategy may adversely affect a collaborator's willingness or ability to complete its obligations under any arrangement;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• under certain circumstances, a collaborator could move forward with a competing product developed either independently or in collaboration with others, including our competitors;

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our current or future collaborators may utilize our proprietary information in a way that could expose us to competitive harm;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our collaborators could obtain ownership or other control over intellectual property that is material to our business; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• collaborative arrangements are often terminated or allowed to expire, which could delay the ability to commercialize our technology.

In addition, if disputes arise between us and any of our collaborators, it could result in the delay or termination of the development, manufacturing or commercialization of products containing our technology, lead to protracted and costly legal proceedings, or cause collaborators to act in their own interest, which may not be in our interest. As a result, the collaborative arrangements that we may enter into, may not achieve their intended goals.

If any of these scenarios materialize, they could have a material adverse effect on our business, financial condition, results of operations and prospects.

We also may have other future products where it is desirable or essential to enter into agreements with a collaborator who has greater financial resources or different expertise than us, but for which we are unable to find an appropriate collaborator or are unable to do so on favorable terms. If we fail to enter into such collaborative agreements on favorable terms, it could materially delay or impair our ability to develop and commercialize, and increase the costs of development and commercialization of, our technology.

***Even if we obtain all necessary FDA approvals, our products and product candidates may not achieve or maintain market acceptance.***

Even if we obtain FDA approval of our products and product candidates, market acceptance of our products in the healthcare community, including physicians, patients and third-party payors, will depend on many factors, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our ability to provide incremental clinical and economic data that shows the safety and clinical efficacy and cost-effectiveness of, and patient benefits from, our products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the availability of alternative products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• whether our products or the use thereof are included on insurance company formularies or coverage plans;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the willingness and ability of patients and the healthcare community to adopt our technologies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• customer demand;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• liability risks generally associated with the use of new product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the training required to use new product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• perceived inadequacy of evidence supporting clinical benefits or cost-effectiveness over existing alternatives;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the convenience and ease of use of our products relative to other treatment methods;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the pricing and reimbursement of our products relative to other treatment methods; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the marketing and distribution support for our products.

Even if we obtain all necessary FDA approvals, our products may fail to achieve market acceptance. If our products achieve market acceptance, they may not maintain that market acceptance over time if competing products or technologies are introduced that are received more favorably or are more cost-effective. Failure to achieve or maintain market acceptance would limit our ability to generate revenue and would have a material adverse effect on our business, financial condition, results of operations and prospects.

***The outcome of any future claims and litigation could have a material adverse impact on our business, financial condition and results of operations.***

We may, from time to time, be subject to claims and may become party to litigation in the normal course of business, including class action lawsuits. Such claims and litigation proceedings may be brought by third parties, including our

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

customers, competitors, advisors, service providers, partners or collaborators, employees, and governmental or regulatory bodies. The final outcome of these claims and litigation, including any settlements, may be significant and may differ substantially from our expectations. We may not be able to determine the amount of any potential losses and other costs we may incur due to the inherent uncertainties of litigation and settlement negotiations. In the event we are required or decide to pay amounts in connection with any claims or lawsuits, such amounts could be significant and could have a material adverse impact on our liquidity, business, financial condition and results of operations.

***We could become subject to product liability claims, product recalls, and warranty claims that could be expensive, divert management's attention and harm our business reputation and financial results.***

Our business exposes us to potential liability risks that are inherent in the marketing and sale of products used in patient care. We may be held liable if the QT Breast Scanner or our products and services under development causes injury or death or is found otherwise unsuitable during usage. The QT Breast Scanner and products and services currently under development incorporate sophisticated components and computer software. Complex software can contain errors, particularly when first introduced. In addition, new products or enhancements may contain undetected errors or performance problems that, despite testing, are discovered only after installation. Patients could allege or possibly prove defects of our products or other products that integrate our technology.

A product liability claim, regardless of its merit or eventual outcome, could result in significant legal defense costs and divert management's attention. Regardless of merit or eventual outcome, liability claims may result in:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• injury to our reputation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• costs of related litigation and substantial monetary awards to patients and others;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• decreased demand for our products and services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• loss of revenue; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the inability to commercialize future products.

Any of these outcomes may have an adverse effect on our business, financial condition and results of operations, and may increase the volatility of our share price.

The coverage limits of our insurance policies we may choose to purchase to cover related risks may not be sufficient to cover future claims. If sales of the QT Breast Scanner and other products and services under development suffer future product liability claims, we may be unable to maintain product liability insurance at satisfactory rates or with adequate amounts or at all. A product liability claim, any product recalls or excessive warranty claims, whether arising from defects in design or manufacture or otherwise, could negatively affect our sales or require a change in the design or manufacturing process, any of which could harm our relationship with our customers and partners, and have a material adverse impact on our reputation and business, financial condition, results of operations and prospects.

In addition, if the QT Breast Scanner or other products integrating our technology are defective, we, our future customers or partners may be required to notify regulatory authorities and/or to recall the products and discontinue any services See "*—Risks Related to Healthcare Industry Shifts and Government Regulation—Our products may cause or contribute to adverse medical events or be subject to failures or malfunctions that we are required to report to the FDA, and if we fail to do so, we would be subject to sanctions that could harm our reputation, business, financial condition and results of operations. The discovery of serious safety issues with our products, or a recall of our products either voluntarily or at the direction of the FDA or another governmental authority, could have a negative impact on us*." Any recall would divert management's attention and financial resources and harm our reputation with customers, patients, medical professionals and third-party payors. A recall involving the QT Breast Scanner or our products under development, would be particularly harmful to our business. The adverse publicity resulting from any of these actions could adversely affect the perception of our customers or partners. These investigations or recalls, especially if accompanied by unfavorable publicity, could result in our incurring substantial costs, losing revenues and damaging our reputation, each of which would harm our business, financial condition, results of operations and prospects.

***We do not expect to carry any business interruption insurance or any other insurance (except for director and officer, property and product liability insurance). As a result, we may incur uninsured losses, increasing the possibility that you would lose your entire investment in our company.***

Our products and services are in the medical imaging field and so may be subject to claims. We are not immune from product liability or other product claim risks, and we may not be able to maintain insurance on acceptable terms against such risks or that such insurance will be sufficient to protect us against potential claims or that insurance will be available in the future in amounts sufficient to protect us. A product liability claim or other claim, as well as any claims for uninsured liabilities or in excess of insured liabilities, could have a material adverse effect on our business, financial condition, results of operations and prospects.

***The mishandling or the perceived mishandling of sensitive information, or the occurrence of data security breaches, could harm our business.***

We expect that the QT Breast Scanner and our products under development will enable us to accumulate a significant amount of highly sensitive and/or confidential information, including medical images and other medical information. These images could be received by our customers or collaborators, such as radiologists and other professionals at cancer screening and other healthcare facilities, to increase the probability of early disease detection. While employee contracts generally contain standard confidentiality provisions, our employees, customers or collaborators may not properly handle or process sensitive or confidential data. The improper handling of sensitive or confidential data, or even the perception of such mishandling (whether or not valid), or other security lapses by us, our customers or collaborators, could reduce demand for such products or otherwise expose us to financial or reputational harm or legal liability. In addition, any security breach, including personal data breaches, or incident, including cybersecurity incidents, that we experience could result in unauthorized access to, misuse of, or unauthorized acquisition of the sensitive or confidential information and data (including medical information), the loss, corruption, or alteration of this data, interruptions in our operations, or damage to our systems. Any such incidents could expose us to claims, litigation, regulatory or other governmental investigations, administrative fines and potential liability. An increasing number of digital platforms have disclosed breaches of their security, some of which have involved sophisticated and highly targeted attacks on portions of their services. Because the techniques used to obtain unauthorized access, disable or degrade service, or sabotage systems change frequently and often are not foreseeable or recognized until launched against a target, we may be unable to anticipate these techniques or to implement adequate preventative measures. If an actual or perceived breach of our security occurs, public perception of the effectiveness of our security measures and brand could be harmed and our results of operations could be negatively affected. Data security breaches and other incidents may also result from non-technical means (e.g., actions by employees or contractors). Any compromise of our security could result in a violation of applicable security, privacy or data protection, consumer and other laws, regulatory or other governmental investigations, enforcement actions, and legal and financial exposure, including potential contractual liability. Any such compromise could also result in damage to our reputation and a loss of confidence in our security and privacy or data protection measures. Any of these effects could materially and adversely affect our business, financial condition and results of operations.

***Our business and operations would suffer in the event of computer system failures, cyber-attacks or deficiencies in our cyber-security.***

Our ability to execute our business strategy depends, in part, on the continued and uninterrupted performance of our IT systems, which support our operations. Despite the implementation of security measures, our internal computer systems, and those of third parties on which we rely, are vulnerable to damage from, among others, computer viruses, malware, natural disasters, terrorism, war, telecommunication and electrical failures, cyber-attacks or cyber-intrusions over the internet, attachments to emails, persons inside our organization, or persons with access to systems inside our organization or similar disruptive problems. The risk of a security breach or disruption, particularly through cyber-attacks or cyber intrusion, including by computer hackers, foreign governments, and cyber terrorists, has generally increased as the number, intensity and sophistication of attempted attacks and intrusions from around the world have increased. If such an event were to occur and cause interruptions in our operations, it could result in a material disruption of our product development programs. Any such security breach may compromise information stored on our networks and may result in significant data losses or theft of personally identifiable information. A cybersecurity breach could also hurt our reputation by adversely affecting the patients' perception of the security of their information. A number of proposed and enacted federal, state and international laws and regulations obligate companies to notify individuals of security breaches involving particular personally identifiable information, which could result from breaches experienced by us or by third parties, including collaborators, vendors, contractors or other organizations with which we expect to form strategic relationships. In addition, a cybersecurity attack could result in other negative consequences, including disruption of our internal operations, increased cyber security protection costs, lost revenue, regulatory actions or litigations.

***Cyber-attacks and security vulnerabilities could lead to reduced revenue, increased costs, liability claims, or harm to our competitive position.***

Increased sophistication and activities of perpetrators of cyber-attacks have resulted in an increase in information security risks in recent years. Hackers develop and deploy viruses, worms, and other malicious software programs that attack products and services and gain access to networks and data centers. In addition to extracting sensitive information, such attacks could include the deployment of harmful malware, ransomware, denial-of-service attacks, social engineering and other means to affect service reliability and threaten the confidentiality, integrity and availability of information. The prevalent use of mobile devices also increases the risk of data security incidents. If we experience difficulties maintaining existing systems or implementing new systems, we could incur significant losses due to disruptions in our operations.

Additionally, these systems contain valuable proprietary and confidential information and may contain personal data of our customers. While we believe we have taken reasonable steps to protect such data, techniques used to gain unauthorized access to data and systems, disable or degrade service, or sabotage systems, are constantly evolving, and we may be unable to anticipate such techniques or implement adequate preventative measures to avoid unauthorized access or other adverse impacts to such data or our systems. In addition, some of our third-party service providers and partners also collect and/or store our sensitive information and our customers' data on our behalf, and these service providers and partners are subject to similar threats of cyber-attacks and other malicious internet-based activities, which could also expose us to risk of loss, litigation, and potential liability. A security breach could result in disruptions of our internal systems and business applications, harm to our competitive position from the compromise of confidential business information, or subject us to liability under laws that protect personal data. Additionally, actual, potential or anticipated attacks may cause us to incur increasing costs, including costs to deploy additional personnel and protection technologies, train employees, and engage third-party experts and consultants. Specifically, as cyber threats continue to evolve, we may be required to expend additional resources to continue to enhance our information security measures and/or to investigate and remediate any information security vulnerabilities. Any of these consequences would adversely affect our revenue and margins. Additionally, even if we purchase cybersecurity insurance coverage, we cannot be certain that such coverage will be adequate for data security liabilities actually incurred, will cover any indemnification claims against us relating to any incident, will continue to be available to us on economically reasonable terms, or at all, or that any insurer will not deny coverage as to any future claim. The successful assertion of one or more large claims against us that exceed available insurance coverage, or the occurrence of changes in our insurance policies, including premium increases or the imposition of large deductible or co-insurance requirements, could have a material adverse effect on our reputation, business, prospects, results of operations and financial condition.

***We are exposed to data and cybersecurity risks that could result in data breaches, service interruptions, ransomware and demands, harm to our reputation, protracted and costly litigation or significant liability.***

In connection with the products and services that we provide, we collect, use, store, transmit and otherwise process certain confidential, proprietary and sensitive information, including personally identifiable information and PHI of customers, employees and others. We rely on the efficient, uninterrupted and secure operation of complex information technology systems and networks to operate our business and securely store, transmit and otherwise process such information. In the normal course of business, we also share information with our service providers and other third parties. A failure to safeguard the integrity, confidentiality, availability and authenticity of personal information, customer data and our proprietary data from cyber-attacks, unauthorized access, fraudulent activity (e.g., check "kiting" or fraud, wire fraud or other dishonest acts), data breaches, ransomware and other security incidents that we, our third-party service providers or our customers may experience may lead to modification, destruction, loss of availability or theft of critical and sensitive data pertaining to us, our customers or other third parties. While we have taken extensive precautions to protect such confidential, proprietary and sensitive information, including personal information, these risks were heightened due to our remote workforce due to the COVID-19 pandemic, and there can be no assurance that such actions will be sufficient to prevent cyber-attacks or security breaches or mitigate all potential risks to our systems, networks and data, particularly with the recent proliferation of ransomware attacks around the world. All such protective measures, as well as additional measures that may be required to comply with rapidly evolving data privacy and security standards and protocols imposed by law, regulation, industry standards or contractual obligations, have and will continue to cause us to incur substantial expenses. Failure to timely upgrade or maintain computer systems, software and networks as necessary could also make us or our third-party service providers susceptible to breaches and unauthorized access and misuse. We may be required to expend significant additional resources to modify, investigate or remediate vulnerabilities or other exposures arising from data and cybersecurity risks.

Improper access to our or our third-party service providers' systems or databases could result in the theft, publication, deletion or modification of confidential, proprietary or sensitive information, including personal information. An actual or perceived breach of our security systems or those of our third-party service providers may require notification under

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

applicable data privacy regulations or contractual obligations. The accidental or unauthorized access to or disclosure, loss, destruction, disablement, corruption or encryption of, use or misuse of or modification of our, our customers' or other third parties' confidential, proprietary or sensitive information, including personal information, by us or our third-party service providers could result in significant fines, penalties, orders, sanctions and proceedings or actions against us by governmental bodies and other regulatory authorities, customers or third parties, which could materially and adversely affect our business, financial condition and results of operations. Any such proceeding or action, and any related indemnification obligations, could damage our reputation, force us to incur significant expenses in defense of such proceeding or action, distract our management, increase our costs of doing business or result in the imposition of financial liability.

Despite our efforts to ensure the integrity, confidentiality, availability, and authenticity of our proprietary systems and information, it is possible that we may not be able to anticipate or to implement effective preventive measures against all cyber threats. No security solution, strategy, or measures can address all possible security threats or block all methods of penetrating a network or otherwise perpetrating a security incident. The risk of unauthorized circumvention of our security measures or those of our third-party providers, customers and partners has been heightened by advances in computer and software capabilities and the increasing sophistication of hackers, including those operating on behalf of nation-state actors, who employ complex techniques involving the theft or misuse of personal and financial information, counterfeiting, "phishing" or social engineering incidents, account takeover attacks, denial or degradation of service attacks, malware, fraudulent payment and identity theft. Because the techniques used by hackers change frequently and are increasingly complex and sophisticated, and new technologies may not be identified until they are launched against a target, we and our third-party service providers may be unable to anticipate these techniques or detect an incident, assess its severity or impact, react or appropriately respond in a timely manner or implement adequate preventative measures. Our systems are also subject to compromise from internal threats, such as theft, misuse, unauthorized access or other improper actions by employees, service provides and other third parties with otherwise legitimate access to our systems or databases. The latency of a compromise is often measured in months, but could be years, and we may not be able to detect a compromise in a timely manner.

Due to applicable laws and regulations or contractual obligations, we may also be held responsible for any failure or cybersecurity breaches attributed to our third-party service providers as they relate to the information that we share with them. Although we generally have agreements relating to data privacy and security in place with our third-party service providers, they are limited in nature and we cannot guarantee that such agreements will prevent the accidental or unauthorized access to or disclosure, loss, destruction, disablement, corruption or encryption of, use or misuse of or modification of confidential, proprietary or sensitive information, including personal information, or enable us to obtain reimbursement from third-party service providers in the event we should suffer incidents resulting in accidental or unauthorized access to or disclosure, loss, destruction, disablement or encryption of, use or misuse of or modification of confidential, proprietary or sensitive information, including personal information. In addition, because we do not control our third-party service providers and our ability to monitor their data security is limited, we cannot ensure the security measures they take will be sufficient to protect confidential, proprietary or sensitive information (including personal information).

Regardless of whether a security incident or act of fraud involving our solutions is attributable to us or our third-party service providers, such an incident could, among other things, result in improper disclosure of information, harm our reputation and brand, reduce the demand for our products and services, lead to loss of customer business or confidence in the effectiveness of our security measures, disrupt normal business operations or result in our systems or products and services being unavailable. In addition, such incidents may require us to spend material resources to investigate or correct the incident and to prevent future security incidents, expose us to uninsured liability, increase our risk of regulatory scrutiny, expose us to protracted and costly litigation, trigger indemnity obligations, result in damages for contract breach, divert the attention of management from the operation of our business and otherwise cause us to incur significant costs or liabilities, any of which could affect our financial condition, results of operations and reputation. Moreover, there could be public announcements regarding any such incidents and any steps we take to respond to or remediate such incidents, and if securities analysts or investors perceive these announcements to be negative, it could, among other things, have a substantial adverse effect on the price of our common stock. In addition, our remediation efforts may not be successful. Further, any adverse findings in security audits or examinations could result in reputational damage to us, which could reduce the use and acceptance of our solutions, cause our customers to cease doing business with us or have a significant adverse impact on our revenue and future growth prospects. Furthermore, even if not directed at us specifically, attacks on other financial institutions could disrupt the overall functioning of the financial system or lead to additional regulation and oversight by federal and state agencies, which could impose new and costly compliance obligations.

***If we fail to maintain properly the integrity or availability of our data or successfully consolidate, integrate, upgrade or expand our existing information systems, or if our technology products do not operate as intended, our business could be materially and adversely affected.***

Our business depends on the integrity and timeliness of the data we use to serve our members, customers and health care professionals and to operate our business. If the data we rely upon to run our businesses is found to be inaccurate or unreliable or if we fail to maintain or protect our information systems and data integrity effectively, we could experience failures in our health, wellness and information technology products; lose existing customers; have difficulty attracting new customers; experience problems in determining medical cost estimates and establishing appropriate pricing; have difficulty preventing, detecting and controlling fraud; have disputes with customers, physicians and other health care professionals; become subject to regulatory sanctions, penalties, investigations or audits; incur increases in operating expenses; or suffer other adverse consequences. The volume of health care data generated, and the uses of data, including electronic health records, are rapidly expanding. Our ability to implement new and innovative services, automate and deploy new technologies to simplify administrative processes and clinical decision making, price our products and services adequately, provide effective service to our customers and consumers in an efficient and uninterrupted fashion, provide timely payments to care providers, and report accurately our results of operations depends on the integrity of the data in our information systems. In addition, connectivity among technologies is becoming increasingly important and recent trends toward greater consumer engagement in health care require new and enhanced technologies, including more sophisticated applications for mobile devices. Our information systems require an ongoing commitment of significant resources to maintain, protect and enhance existing systems and develop new systems to keep pace with continuing changes in information processing technology, evolving systems and regulatory standards and changing customer preferences. We periodically consolidate, integrate, upgrade and expand our information systems' capabilities as a result of technology initiatives, recently enacted regulations, changes in our system platforms and integration of new business acquisitions. Our process of consolidating the number of systems we operate, upgrading and expanding our information systems' capabilities, enhancing our systems and developing new systems to keep pace with continuing changes in information processing technology may not be successful. Failure to protect, consolidate and integrate our systems successfully could result in higher than expected costs and diversion of management's time and energy, which could materially and adversely affect our results of operations, financial position and cash flows. Certain of our businesses sell and install software products which may contain unexpected design defects or may encounter unexpected complications during installation or when used with other technologies utilized by the customer. A failure of our technology products to operate as intended and in a seamless fashion with other products could materially and adversely affect our results of operations, financial position and cash flows. Uncertain and rapidly evolving U.S. federal and state, non-U.S. and international laws and regulations related to health data and the health information technology market may alter the competitive landscape or present compliance challenges and could materially and adversely affect the configuration of our information systems and platforms, and our ability to compete in this market.

***If significant tariffs or other restrictions related to "trade wars" are placed on U.S. made products or any related counter-measures are taken by any of the countries in which we operate or expect to operate, our revenue and results of operations may be materially harmed.***

We have entered into the Canon Manufacturing Agreement with CMSC for the manufacture of the QT Breast Scanner in Japan, and may also have agreements we expect to enter into with manufacturers and/or suppliers in Asia for the volume production of components, sub-assemblies or the full assembly of the QT Breast Scanner and other products under development. If significant tariffs or other restrictions are placed by the United States government on imports or any related counter-measures are taken by the countries in which we have such manufacturing and outsourcing agreements, our business, financial condition and results of operations may be materially harmed. Alternatively, we may seek to shift production outside of the affected countries subject to tariffs or other restrictions, resulting in significant costs and disruption to our operations and business. Our business could also be impacted by retaliatory trade measures taken by other countries in response to existing or future tariffs, causing us to raise prices or make changes to our operations, any of which could materially harm our business, financial condition and results of operations.

***Our business may be impacted by changes in general economic conditions.***

Our business is subject to risks arising from changes in domestic and global economic conditions, including adverse economic conditions in markets in which we operate, which may harm our business. For example, the COVID-19 pandemic caused significant volatility and uncertainty in U.S. and international markets. Similar volatility and uncertainty could result from the imposition of tariffs and other trade restrictions intended to have an impact on global supply chains, which may harm our business. If our manufacturers and supplies cannot supply us with materials and product at the cost that we have planned upon, we could see increased expense in the production of the QT Breast Scanner. If our future

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

customers significantly reduce spending in areas in which our technology and products are utilized, or prioritize other expenditures over our technology and products, our business, financial condition, results of operations and prospects would be materially adversely affected.

Disruption to the global economy could also result in a number of follow-on effects on our business, including a possible slow–down resulting from lower customer expenditures; inability of customers to pay for products, solutions or services on time, if at all; more restrictive export regulations which could limit our potential customer base; negative impact on our liquidity, financial condition and share price, which may impact our ability to raise capital in the market, obtain financing and secure other sources of funding in the future on terms favorable to us.

In addition, the occurrence of catastrophic events, such as hurricanes, storms, earthquakes, tsunamis, floods, medical epidemics and other catastrophes that adversely affect the business climate in any of our markets could have a material adverse effect on our business, financial condition and results of operations.

***Technological change may adversely affect sales of our products and may cause our products to become obsolete.***

The medical device market is characterized by extensive research and development, and rapid technological change. Technological progress or new developments in our industry could adversely affect clinical adoption of QT Breast Scanner and our other products under development, which could be rendered obsolete because of future innovations by our competitors with traditional methods like MRI, HHUS or mammography. We may be limited by resources, including qualified personnel, funds for capital investments, and other constraints from offering improvements to our products and services and our business, operating results and financial condition will suffer as a result.

***Employee attrition may have an adverse impact on our business, results of operations or internal controls.***

Our ability to attract, retain and develop qualified and experienced employees, including key executives and other talent, is critical for us to meet our business objectives. We compete with many other businesses to attract and retain employees. It is possible that we could experience loss of key personnel for a variety of causes. If we do not adequately plan for succession of key roles or if we are not successful in attracting or retaining new talent, our performance or internal control over financial reporting could be adversely impacted.

***We plan to expand our operations and may not be able to manage our growth effectively, which could strain our resources and delay or derail implementation of our business objectives.***

We will need to significantly expand our operations to implement our longer-term business plan and growth strategies, including building and expanding our internal organizational infrastructure to manage the regulatory approval process with the FDA for our product candidates. We will also be required to manage and form new relationships with various strategic partners, technology licensors, customers, manufacturers and suppliers, consultants and other third parties. This expansion and these new relationships will require us to significantly improve or replace our existing managerial, operational and financial systems, and procedures and controls; to improve the coordination between our various corporate functions; and to manage, train, motivate and maintain a growing employee base. The time and costs to effectuate these steps may place a significant strain on our management personnel, systems and resources, particularly if there are limited financial resources and skilled employees available at the time. We cannot assure that we will institute, in a timely manner or at all, the improvements to our managerial, operational and financial systems, procedures and controls necessary to support our anticipated increased levels of operations and to coordinate our various corporate functions, or that we will be able to properly manage, train, motivate and retain our anticipated increased employee base. If we cannot manage our growth initiatives, we will be unable to commercialize our products on a large-scale in a timely manner, if at all, and our business could fail.

***If we do not manage our growth or control costs related to growth, our financial condition, results of operations and future growth prospects will suffer.***

Our existing systems, facilities, procedures and personnel may not be adequate to support our future growth and operations. We intend to grow our business by expanding our customer base, sales force, and product offerings. Growth could place significant strain on our management, employees, operations, financial systems, and other resources. To accommodate significant growth, we could be required to open additional facilities, expand and improve or information systems and procedures, and hire, train, motivate and manage a growing workforce, all of which would increase our costs. Further, we may not succeed in our plans to accelerate or manage growth by expanding operations, personnel and other resources, or achieve results that are timely and profitable.

***If we are unable to anticipate or keep pace with changes in the marketplace and the direction of technological innovation and customer demands, our technology may become less useful or obsolete and our operating results and financial condition will suffer.***

Companies offering traditional medical imaging systems, such as General Electric, Siemens, Philips, Hologic, Varian, Fuji, Canon and Hitachi, are better established in the market than we are, have greater corporate, financial, operational, sales and marketing resources than we do, or have more experience in research and development than we have. Successful developments by these companies using 3D ultralow frequency transmitted sound imaging or other technologies by competitors resulting in new approaches for medical imaging, including technologies, products or services that are more effective or commercially attractive, could make our technology less useful or obsolete. We may also face opposition from certain industry leaders, who may have political influence and the ability to delay deployment of QT Breast Scanner and other products under development in certain geographical areas.

Our competitive position also depends on our ability to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• generate widespread awareness, acceptance and adoption of our technology and future products or services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• develop new or enhanced technologies or features that improve the convenience, efficiency, safety or perceived safety, and productivity of our technology and future products or services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• properly identify customer needs and deliver new products or services or product enhancements to address those needs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit the time required from prototype development to commercial production;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limit the timing and cost of regulatory approvals;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• attract and retain qualified personnel and collaborators;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• protect our inventions with patents or otherwise develop proprietary products and processes; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• secure sufficient capital resources to expand both our continued research and development, and sales and marketing efforts.

If our technology is not, or our future products or services are not, competitive based on these or other factors, our business would be harmed.

***We may be unable to sustain revenue growth or profitability.***

Our ability to increase revenue in future periods will depend on our ability to successfully penetrate our target markets and increase sales of our products which will, in turn, depend in part on our success in growing our customer base and obtaining reorders from those customers. New products and services will also need to be developed and approved or cleared by the FDA and foreign regulatory agencies. Our ability to become profitable and sustain profitability is highly dependent on our ability to sustain revenue growth and to successfully manage our costs. We are also subject to potential headwinds—adverse economic conditions in the markets we serve, political turmoil, pandemic and disease, acts of God, and other unforeseen factors beyond our control that may affect our ability to sustain revenue and profitability.

***Our marketing efforts, including any social media marketing efforts that we may implement in the future, may expose us to additional regulatory scrutiny, including from the FTC and other consumer protection agencies and regulators.***

In addition to the laws and regulations enforced by the FDA, advertising for various services and for non-restricted medical devices is subject to federal truth-in-advertising laws enforced by the FTC, as well as comparable state consumer protection laws. The Company's efforts to promote its prescription products via direct-to-consumer marketing and social media initiatives may subject us to additional scrutiny of its practices. For example, the FTC and other consumer protection agencies scrutinize all forms of advertising (whether in digital or traditional formats) for business services, consumer-directed products, and non-restricted medical devices to ensure that advertisers are not making false, misleading or unsubstantiated claims or failing to disclose material relationships between the advertiser and its products' endorsers, among other potential issues. The FDA oversees the advertising and promotional labeling for restricted medical devices and ensures, among other things, that there is effective communication of, and a fair and balanced presentation of, the risks and benefits of such high-risk medical devices.

Under the Federal Trade Commission Act ("***FTC Act***"), the FTC is empowered, among other things, to (a) prevent unfair methods of competition and unfair or deceptive acts or practices in or affecting commerce; (b) seek monetary redress and other relief for conduct injurious to consumers; and (c) gather and compile information and conduct investigations relating to the organization, business, practices, and management of entities engaged in commerce. The FTC has very broad enforcement authority, and failure to abide by the substantive requirements of the FTC Act and other consumer protection laws can result in administrative or judicial penalties, including civil penalties, injunctions affecting the manner in which the Company would be able to market services or products in the future, or criminal prosecution. Any plans to increase our advertising activities that may be subject to these federal and state truth-in-advertising laws. Any actual or perceived non-compliance with those laws could lead to an investigation by the FTC or a comparable state agency, or could lead to allegations of misleading advertising by private plaintiffs. Any such action against us would disrupt the Company's business operations, cause damage to our reputation, and result in material adverse effects on our business and financial performance.

The FDA requires that promotional labeling be truthful and not misleading, including with respect to any comparative claims made about competing products or technologies. In addition to FDA implications, the use of comparative claims also present risk of a lawsuit by the competitor under federal and state false advertising and unfair competition statutes (e.g., the Lanham Act) or unfair and deceptive trade practices law, and possibly also state libel law. Such a suit may seek injunctive relief against further advertising, a court order directing corrective advertising, and compensatory and punitive damages where permitted by law. Further, notwithstanding the ultimate outcome of any Lanham Act or similar complaint, the Company's reputation and relationship with certain customers or distribution partners may be harmed as a result of the allegations related to its products or its business practices more generally.

**Risks Related to Healthcare Industry Shifts and Government Regulation** 

***We are subject to extensive government regulation, which could restrict the development, marketing, sale and distribution of our products and services, and could cause us to incur significant costs.***

The Company's ultrasound imaging products and associated services are subject to extensive pre-market and post-market regulation by the FDA and various other federal, state, local and foreign government authorities. Government regulation of medical devices is meant to assure their safety and effectiveness, and includes requirements for, among other things: design, development and manufacturing; testing, labeling, content and language of instructions for use and storage; clinical trials; product safety; establishment registration and device listing; marketing, sales and distribution; pre-market clearance and approval; conformity assessment procedures; record keeping procedures; advertising and promotion; recalls and field safety corrective actions; post-market surveillance, including reporting of deaths or serious injuries and malfunctions that, if they were to occur, could lead to death or serious injury; post-market approval studies; and product import and export.

The Company is also subject to numerous post-marketing regulatory requirements, which include quality system regulations related to the manufacture of the Company's devices, labeling regulations and medical device reporting regulations. The last of these regulations requires us to report to the FDA if our devices cause or contribute to a death or serious injury, or malfunction in a way that would likely cause or contribute to a death or serious injury if the malfunction recurred. If we fail to comply with present or future regulatory requirements that are applicable, it may subject our company to enforcement action by the FDA, such as: warning or untitled letters; fines; injunctions; consent decrees; civil penalties; customer notifications; termination of distribution; recalls or seizures of products; administrative detention of medical devices believed to be adulterated or misbranded; delays in the introduction of products into the market; operating restrictions; total or partial suspension of production; refusal to grant future clearances or approvals for new products, new intended uses or modifications to our products; withdrawals or suspensions of current approvals, resulting in prohibitions on sales of our products; and in the most serious cases, criminal prosecution or penalties. The occurrence of any of these events may have a material adverse effect on the Company's business, financial condition and results of operations.

The laws and regulations to which the Company and its products are subject are complex and subject to periodic changes. Regulatory changes could result in restrictions on our ability to carry on or expand our operations, higher than anticipated costs or lower than anticipated sales. See "*Business-Government Regulation*" for a more detailed description of laws and regulations that affect our business and operations.

***Failure to comply with applicable regulation in the United States and in the countries where we will sell and distribute our products could harm our business.***

QT Breast Scanner and other future products we develop are subject to extensive regulation in the U.S. and elsewhere, including by the FDA and its foreign counterparts, the U.S. Department of Justice (the "***DOJ***") and the U.S. Health and Human Services-Office of the Inspector General (the "***OIG***"). The FDA and foreign regulatory agencies regulate, among

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

other things, with respect to medical devices: design, development and manufacturing; testing, labeling, content and language of instructions for use and storage; clinical trials; product safety; establishment registration and device listing; marketing, sales and distribution; pre-market clearance and approval; conformity assessment procedures; record keeping procedures; advertising and promotion; recalls and field safety corrective actions; post-market surveillance, including reporting of deaths or serious injuries and malfunctions that, if they were to occur, could lead to death or serious injury; post-market approval studies; and product import and export.

The regulations for products like QT Breast Scanner, products under development and have tended to become more stringent over time. Regulatory changes could result in restrictions on our ability to carry on or expand our operations, higher than anticipated costs or lower than anticipated sales for any approved product. Failure to comply with applicable regulations could jeopardize our ability to sell our future products, if cleared or approved, and result in enforcement actions such as: warning or untitled letters; fines; injunctions; consent decrees; civil penalties; customer notifications; termination of distribution; recalls or seizures of products; administrative detention of medical devices believed to be adulterated or misbranded; delays in the introduction of products into the market; operating restrictions; total or partial suspension of production; refusal to grant future clearances or approvals for new products, new intended uses or modifications to our products; withdrawals or suspensions of current approvals, resulting in prohibitions on sales of our products; and in the most serious cases, criminal prosecution or penalties. The occurrence of any of these events would have a material adverse effect on our business, financial condition and results of operations and could result in stockholders losing their entire investment.

***We may not receive, or may be delayed in receiving, the necessary clearances or approvals for our future products, and failure to timely obtain necessary clearances or approvals for our future products would adversely affect our ability to grow our business.***

See "*Business-Government Regulation*" for a more detailed description of laws and regulations that affect our business and operations. In the United States, before we can market a new medical device, or a new use of, new claim for or significant modification to an existing product, we must first receive either clearance under Section 510(k) of the FDCA or approval of a PMA from the FDA, unless an exemption applies. Clinical data are sometimes required to support a pre-market approval application. In the process of obtaining PMA approval, the FDA must determine that a proposed device is safe and effective for its intended use based, in part, on extensive data, including, but not limited to, technical, pre-clinical, clinical trial, manufacturing and labeling data. The PMA process is typically required for devices that are deemed to pose the greatest risk, such as life-sustaining, life-supporting or implantable devices. While we do not expect our products to be marketed under a PMA, should the FDA require we submit to a PMA approval process for any of our products, our business could suffer due to increased costs and timelines to receive such approvals.

If the FDA requires us to submit new 510(k) notifications or PMA applications for modifications to our previously cleared products for which we have concluded that new clearances or approvals are unnecessary, we may be required to cease marketing or to recall the modified product until we obtain clearance or approval, and we may be subject to significant regulatory fines or penalties. If the FDA requires us to go through a lengthier, more rigorous examination for future products or modifications to existing products than we had expected, product introductions or modifications could be delayed or canceled, which could adversely affect our ability to grow our business.

The FDA can delay, limit or deny clearance or approval of a medical device for many reasons, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our inability to demonstrate to the satisfaction of the FDA or the applicable regulatory entity or notified body that our product candidates are safe or effective for their intended uses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the disagreement of the FDA or the applicable foreign regulatory body with the design or implementation of our clinical trials or the interpretation of data from pre-clinical studies or clinical trials;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• serious and unexpected adverse effects experienced by participants in our clinical trials;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the data from our pre-clinical studies and clinical trials may be insufficient to support clearance or approval, where required;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our inability to demonstrate that the clinical and other benefits of the device outweigh the risks;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the manufacturing process or facilities we use may not meet applicable requirements; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the potential for approval policies or regulations of the FDA or applicable foreign regulatory bodies to change significantly in a manner rendering our clinical data or regulatory filings insufficient for clearance or approval.

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

In order to sell our products in member countries of the European Economic Area ("***EEA***"), our products must comply with the essential requirements of the EU Medical Devices Directive (Council Directive 93/42/EEC). Compliance with these requirements is a prerequisite to be able to affix the Conformité Européene ("***CE***") mark to our products, without which they cannot be sold or marketed in the EEA. To demonstrate compliance with the essential requirements we must undergo a conformity assessment procedure, which varies according to the type of medical device and its classification. Except for low-risk medical devices (Class I non-sterile, non-measuring devices), where the manufacturer can issue a European Community ("***EC***") Declaration of Conformity based on a self-assessment of the conformity of its products with the essential requirements of the EU Medical Devices Directive, a conformity assessment procedure requires the intervention of an organization accredited by a member state of the EEA to conduct conformity assessments, or a Notified Body. Depending on the relevant conformity assessment procedure, the Notified Body would typically audit and examine the technical file and the quality system for the manufacture, design and final inspection of our devices. The Notified Body issues a certificate of conformity following successful completion of a conformity assessment procedure conducted in relation to the medical device and its manufacturer and their conformity with the essential requirements. This certificate entitles the manufacturer to affix the CE mark to its medical devices after having prepared and signed a related EC Declaration of Conformity.

The Company cannot be certain that it will be successful in meeting and continuing to meet the requirements to market a medical device in the EEA under the new regulatory framework called the MDR. The MDR went into force in May 2017 but allowed a three-year transition period until May 2020 for Member States, regulatory authorities, and medical device stakeholders to come into compliance with the new requirements. A one-year delay of the compliance date of the MDR was implemented in response to the COVID-19 pandemic, and the directive entered into application on May 26, 2021. Compared to the earlier regulatory framework of Medical Device Directive, the MDR promotes a shift from the pre-approval stage (i.e., the path to CE Marking) to a life-cycle approach and places greater emphasis on clinical data and clinical evaluations to assure the safety and performance of new medical devices. Moreover, the MDR includes elements intended to strengthen the conformity assessment procedures, assert greater control over notified bodies and their standards, increase overall system transparency, and impose more robust device vigilance requirements on manufacturers and distributors. The new rules and procedures that have been created under the overhauled European regulations will likely result in increased regulatory oversight of all medical devices marketed in the European Union, and this may, in turn, increase the costs, time and requirements that need to be met in order to place an innovative or high-risk medical device on the EEA market.

As a general rule, demonstration of conformity of medical devices and their manufacturers with the essential requirements must be based, among other things, on the evaluation of clinical data supporting the safety and performance of the products during normal conditions of use. Specifically, a manufacturer must demonstrate that the device achieves its intended performance during normal conditions of use, that the known and foreseeable risks, and any adverse events, are minimized and acceptable when weighed against the benefits of its intended performance, and that any claims made about the performance and safety of the device are supported by suitable evidence. If we fail to remain in compliance with applicable European laws and directives, we would be unable to continue to affix the CE mark to our products, which would prevent us from selling them within the EEA. Approval and CE marking procedures vary between countries and can involve additional product testing and additional administrative review periods. The time required to obtain approval or CE mark in other countries might differ from that required to obtain FDA clearance. The regulatory approval or CE marking process in other countries may include all of the risks detailed above regarding FDA clearance in the United States. Regulatory approval or the CE marking of a product in one country does not ensure regulatory approval in another, but a failure or delay in obtaining regulatory approval or a CE mark in one country may negatively impact the regulatory process in others. Failure to obtain regulatory approval or a CE mark in other countries or any delay or setback in obtaining such approval could have the same adverse effects described above regarding FDA clearance in the United States.

***Recent initiatives by the FDA to enhance and modernize various regulatory pathways for device products and its overall approach to safety and innovation in the medical technology industry creates the possibility of changing product development costs, requirements, and other factors and additional uncertainty for the Company's future products and business.***

Regulatory requirements may change in the future in a way that adversely affect the Company. Any change in the laws or regulations that govern the clearance and approval processes or the post-market compliance requirements relating to the Company's current and future products and associated services could make it more difficult and costly to obtain clearance or approval for new products, or to produce, market and distribute existing products. For example, the FDA and other government agencies have been focusing on the cybersecurity risks associated with certain medical devices and encouraging device manufacturers to take a more proactive approach to assessing the cybersecurity risks of their devices both during development and on a periodic basis after the devices are in commercial distribution. These regulatory efforts

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

could lead to new FDA requirements in the future or additional product liability or other litigation risks, if any of the Company's products and associated services are considered susceptible to third-party tampering.

In December 2016, Congress passed the 21st Century Cures Act, which made multiple changes to the FDA's rules for medical devices as well as for clinical trials. In August 2017, Congress passed the Medical Device User Fee reauthorization package, which affects medical device regulation both pre- and post-approval and could have certain impacts on our business. Since that time, the FDA has announced a series of efforts to modernize and streamline the 510(k) notification and regulatory review process and monitoring post-market safety, and issued a proposed rule to formalize the de novo classification process to provide clarity to innovative device developers. Changes in the FDA 510(k) process could make clearance more difficult to obtain, increase delay, add uncertainty and have other significant adverse effects on our ability to obtain and maintain clearance for the Company's products and associated services.

It is unclear at this time whether and how various activities initiated or announced by the FDA to modernize the U.S. medical device regulatory system could affect the Company's business, as some of the FDA's new medical device safety and innovation initiatives have not been formalized and remain subject to change. For example, a 2018 Medical Device Safety Action Plan announced by former FDA Commissioner Gottlieb included a particular focus on post-market surveillance and how to respond when new safety concerns emerge once a product is on the market. The increased attention that the medical technology industry is receiving from FDA leadership that understands the challenging and rapidly changing nature of the U.S. health care system creates the possibility of unanticipated regulatory and other potential changes to the Company's products and its overall business.

***Failure to comply with post-marketing regulatory requirements could subject us to enforcement actions, including substantial penalties, and might require us to recall or withdraw a product from the market.***

We are subject to ongoing and pervasive regulatory requirements governing, among other things, the manufacture, marketing, advertising, medical device reporting, sale, promotion, import, export, registration, and listing of devices. For example, we are required to submit periodic reports to the FDA as a condition of 510(k) clearance. These reports include information about failures and certain adverse events associated with the device after its clearance. Failure to submit such reports, or failure to submit the reports in a timely manner, could result in enforcement action by the FDA. Following its review of the periodic reports, the FDA might ask for additional information or initiate further investigation.

The regulations to which we are subject are complex and have become more stringent over time. Regulatory changes could result in restrictions on our ability to continue or expand our operations, higher than anticipated costs, or lower than anticipated sales. Even after we have obtained the proper regulatory clearance to market a device, we have ongoing responsibilities under FDA regulations and applicable foreign laws and regulations. The FDA, state and foreign regulatory authorities have broad enforcement powers. Our failure to comply with applicable regulatory requirements could result in enforcement action by the FDA, state or foreign regulatory authorities, which may include any of the following sanctions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• untitled letters or warning letters;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• fines, injunctions, consent decrees and civil penalties;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• recalls, termination of distribution, administrative detention, or seizure of our products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• customer notifications or repair, replacement or refunds;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• operating restrictions or partial suspension or total shutdown of production;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• delays in or refusal to grant our requests for future clearances or approvals or foreign marketing authorizations of new products, new intended uses, or modifications to existing products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• withdrawals or suspensions of product clearances or approvals, resulting in prohibitions on sales of our products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• FDA refusal to issue certificates to foreign governments needed to export products for sale in other countries; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• criminal prosecution.

Any of these sanctions could result in higher than anticipated costs or lower than anticipated sales and have a material adverse effect on our reputation, business, financial condition and results of operations. In addition, the FDA or state or foreign authorities may change their clearance and approval policies, adopt additional regulations or revise existing regulations, or take other actions, which may prevent or delay clearance or approval of our future products under development on a timely basis. Such policy or regulatory changes could impose additional requirements upon us that could

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

delay our ability to obtain new clearances or approvals, increase the costs of compliance or restrict our ability to maintain any approvals we are able to obtain.

***Our products must be manufactured in accordance with federal, state and foreign regulations, and we could be forced to recall our devices or terminate production if we fail to comply with these regulations.***

The methods used in, and the facilities used for, the manufacture of our products must comply with the QSR, which is a complex regulatory scheme that covers the procedures and documentation of the design, testing, production, process controls, quality assurance, labeling, packaging, handling, storage, distribution, installation, servicing and shipping of medical devices. As manufacturers of electron radiation-emitting products, we are also responsible for compliance with the radiological health regulations and certain radiation safety performance standards.

Furthermore, we are required to verify that our suppliers maintain facilities, procedures and operations that comply with our quality standards and applicable regulatory requirements. The FDA enforces the QSR through periodic announced or unannounced inspections of medical device manufacturing facilities, which may include the facilities of subcontractors. Our products are also subject to similar state regulations and various laws and regulations of foreign countries governing manufacturing.

Our third-party manufacturers may not take the necessary steps to comply with applicable regulations, which could cause delays in the delivery of our products. In addition, failure to comply with applicable FDA or state or foreign requirements or later discovery of previously unknown problems with our products or manufacturing processes could result in, among other things: warning letters or untitled letters; fines, injunctions or civil penalties; suspension or withdrawal of approvals; seizures or recalls of our products; total or partial suspension of production or distribution; administrative or judicially imposed sanctions; the FDA's refusal to grant pending or future clearances or approvals for our products; clinical holds; refusal to permit the import or export of our products; and criminal prosecution of us, our suppliers or our employees.

Any of these actions could significantly and negatively affect supply of our products. If any of these events occurs, our reputation could be harmed, we could be exposed to product liability claims and we could lose customers and experience reduced sales and increased costs.

***We have limited experience in identifying and working with large-scale contracts with medical device manufacturers.***

To achieve the levels of production necessary to commercialize the QT Breast Scanner and any other future products or product candidates, we have entered into the Canon Manufacturing Agreement with CMSC for the manufacture of the QT Breast Scanner (and will need to something similar for other future products or product candidates), and by doing so, have secured a large-scale manufacturing agreement with a contract manufacturer that complies with the manufacturing standards prescribed by various federal, state and local regulatory agencies in the U.S. and any other country of use. We have limited experience coordinating and overseeing the manufacturing of medical device products on a large-scale. Manufacturing and control problems could arise as we attempt to commercialize our products and manufacturing may not be completed in a timely manner or at a commercially reasonable cost. In addition, we may not be able to adequately finance the manufacturing and distribution of our products on terms acceptable to us, if at all. If we cannot successfully oversee and finance the manufacturing of our products after receiving regulatory approval, we may not generate sufficient revenue to become profitable.

***The misuse or off-label use of our products may harm our reputation in the marketplace, result in injuries that lead to product liability suits or result in costly investigations, fines or sanctions by regulatory bodies if we are deemed to have engaged in the promotion of these uses, any of which could be costly to our business.***

Advertising and promotion of our existing product, and products under development that obtain approval in the United States may be heavily scrutinized by the FDA, the DOJ, HHS, state attorneys general, members of Congress, and the public. In addition, advertising and promotion of any future product that obtains approval outside of the United States will be heavily scrutinized by comparable foreign regulatory authorities.

The QT Breast Scanner is, and we expect will continue to be, cleared by the requisite regulatory authorities for specific indications. We expect to train our marketing personnel and direct sales force to not promote our devices for uses outside of the FDA-approved indications for use, known as "off-label uses." We cannot, however, prevent a physician from using our devices off-label, when in the physician's independent professional medical judgment, he or she deems it appropriate. There may be increased risk of injury to patients if physicians attempt to use our devices off-label. Furthermore, the use of our devices for indications other than those approved by the FDA or approved by any foreign regulatory body may not effectively treat such conditions, which could harm our reputation in the marketplace among healthcare providers and patients.

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

If the FDA or any state or foreign regulatory body determines that our promotional materials or training constitute promotion of an off-label use, it could request that we modify our training or promotional materials or subject us to regulatory or enforcement actions, including the issuance or imposition of an untitled letter, which is used for violators that do not necessitate a warning letter, injunction, seizure, civil fine or criminal penalties. It is also possible that other federal, state or foreign enforcement authorities might take action under other regulatory authority, such as false claims laws, if they consider our business activities to constitute promotion of an off-label use, which could result in significant penalties, including, but not limited to, criminal, civil and administrative penalties, damages, fines, disgorgement, exclusion from participation in government healthcare programs and the curtailment of our operations. We may become subject to such actions and, if we are not successful in defending against such actions, those actions may have a material adverse effect on our business, financial condition and results of operations. Equivalent laws and potential consequences exist in foreign jurisdictions.

In addition, if our products are cleared or approved, healthcare providers may misuse our products or use improper techniques if they are not adequately trained, potentially leading to injury and an increased risk of product liability. If our devices are misused or used with improper technique, we may become subject to costly litigation by our customers or their patients. As described above, product liability claims could divert management's attention from our core business, be expensive to defend and result in sizeable damage awards against us that may not be covered by insurance.

***Our products may cause or contribute to adverse medical events or be subject to failures or malfunctions that we are required to report to the FDA, and if we fail to do so, we would be subject to sanctions that could harm our reputation, business, financial condition and results of operations. The discovery of serious safety issues with our products, or a recall of our products either voluntarily or at the direction of the FDA or another governmental authority, could have a negative impact on us.***

Our existing product and products under development that receive clearance or approval will be subject to the FDA's medical device reporting regulations and similar foreign regulations, which require us to report to the FDA when we receive or become aware of information that reasonably suggests that one or more of our products may have caused or contributed to a death or serious injury or malfunctioned in a way that, if the malfunction were to recur, could cause or contribute to a death or serious injury. The timing of our obligation to report is triggered by the date we become aware of the adverse event as well as the nature of the event. We may fail to report adverse events of which we become aware within the prescribed timeframe. We may also fail to recognize that we have become aware of a reportable adverse event, especially if it is not reported to us as an adverse event or if it is an adverse event that is unexpected or removed in time from the use of the product. If we fail to comply with our reporting obligations, the FDA or other regulatory bodies could take action, including warning letters, untitled letters, administrative actions, criminal prosecution, imposition of civil monetary penalties, revocation of our device clearance or approval, seizure of our products or delay in clearance or approval of future products.

The FDA and foreign regulatory bodies have the authority to require the recall of commercialized products in the event of material deficiencies or defects in design or manufacture of a product or in the event that a product poses an unacceptable risk to health. The FDA's authority to require a recall must be based on a finding that there is reasonable probability that the device could cause serious injury or death. We may also choose to voluntarily recall a product if any material deficiency is found. A government-mandated or voluntary recall by us could occur as a result of an unacceptable risk to health, component failures, malfunctions, manufacturing defects, labeling or design deficiencies, packaging defects or other deficiencies or failures to comply with applicable regulations. Product defects or other errors may occur in the future.

Depending on the corrective action we take to redress a product's deficiencies or defects, the FDA may require, or we may decide, that we will need to obtain new clearances or approvals for the device before we may market or distribute the corrected device. Seeking such clearances or approvals may delay our ability to replace the recalled devices in a timely manner. Moreover, if we do not adequately address problems associated with our devices, we may face additional regulatory enforcement action, including FDA warning letters, product seizure, injunctions, administrative penalties or civil or criminal fines.

Companies are required to maintain certain records of recalls and corrections, even if they are not reportable to the FDA. We may initiate voluntary withdrawals or corrections for our products in the future that we determine do not require notification of the FDA. If the FDA disagrees with our determinations, it could require us to report those actions as recalls and we may be subject to enforcement action. A future recall announcement could harm our reputation with customers, potentially lead to product liability claims against us and negatively affect our sales. Any corrective action, whether voluntary or involuntary, as well as defending ourselves in a lawsuit, will require the dedication of our time and capital, distract management from operating our business and may harm our reputation and financial results.

***Our QT Breast Scanner technology may become obsolete.***

Our QT Breast Scanner may become obsolete prior to commercialization by new scientific or technological developments, or by others with new technologies that are more efficient, precise and/or more economical than the QT Breast Scanner or our future product candidates. Any one of our competitors could develop a more effective product which would render our technology obsolete. In addition, it is possible that competitors may use similar technologies, equipment or devices to attempt to create a product similar to the QT Breast Scanner. Further, new technological and scientific developments could cause our QT Breast Scanner and future product candidates to become obsolete. Further developments and innovation in the area of medical imaging could require us to reconfigure the QT Breast Scanner or our future product candidates, which may not be commercially feasible, or cause them to become obsolete. Lastly, our ability to achieve significant and sustained growth in our key target markets will depend upon our success in market penetration, utilization, publication, our reimbursement efforts and medical education. Our products may not remain competitive with products based on new technologies. If we fail to sell products that satisfy our customers' demands, or respond effectively to new product announcements by our competitors, then market acceptance of our products could be reduced and our business, results of operations and financial condition could be adversely affected.

***Our relationships with customers and third-party payors will be subject to applicable anti-kickback, fraud and abuse and other healthcare laws and regulations, which could expose us to criminal sanctions, civil penalties, contractual damages, reputational harm and diminished profits and future earnings.***

Physicians, other healthcare providers, and third-party payors will play a primary role with respect to our current products and any future products for which we obtain marketing approval. Our arrangements with third-party payors and customers may expose us to broadly applicable fraud and abuse and other healthcare laws and regulations that may constrain the business or financial arrangements and relationships through which we market, sell and distribute our product. Restrictions under applicable federal and state healthcare laws and regulations include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The U.S. federal healthcare program Anti-Kickback Statute prohibits, among other things, persons from knowingly and willfully soliciting, offering, receiving or providing remuneration, directly or indirectly, in cash or in kind, to induce or reward either the referral of an individual for, or the purchase, order or recommendation of, any good or service, for which payment may be made, in whole or in part, under federal healthcare programs such as Medicare and Medicaid. Although there are a number of statutory exemptions and regulatory safe harbors protecting certain common activities from prosecution, the exemptions and safe harbors are drawn narrowly and practices that involve remuneration to those who prescribe, purchase, or recommend medical devices, including certain discounts, or engaging consultants as speakers or consultants, may be subject to scrutiny if they do not fit squarely within the exemption or safe harbor. Our practices may not in all cases meet all of the criteria for safe harbor protection from anti-kickback liability. Moreover, there are no safe harbors for many common practices, such as educational and research grants. Liability may be established without a person or entity having actual knowledge of the Anti-Kickback Statute or specific intent to violate it. In addition, the government may assert that a claim including items or services resulting from a violation of the Anti-Kickback Statute constitutes a false or fraudulent claim for purposes of the civil False Claims Act. Due to the breadth of these laws, the narrowness of statutory exceptions and regulatory safe harbors available, and the range of interpretations to which they are subject, it is possible that some of our current or future practices might be challenged under one or more of these laws. The Company's compliance with Medicare and Medicaid regulations may be reviewed by federal or state agencies, including the OIG, CMS, and DOJ, or may be subject to whistleblower lawsuits under federal and state false claims laws.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The federal civil False Claims Act prohibits, among other things, any person from knowingly presenting, or causing to be presented, a false or fraudulent claim for payment of government funds, or knowingly making, using, or causing to be made or used, a false record or statement material to an obligation to pay money to the government or knowingly concealing or knowingly and improperly avoiding, decreasing, or concealing an obligation to pay money to the federal government. In recent years, several healthcare companies have faced enforcement actions under the federal False Claims Act for, among other things, allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product or causing false claims to be submitted because of the company's marketing the product for unapproved, and thus non-reimbursable, uses. False Claims Act liability is potentially significant in the healthcare industry because the statute provides for treble damages and mandatory penalties of tens of thousands of dollars per false claim or statement. Healthcare companies also are subject to other federal false claims laws, including, among others, federal criminal healthcare fraud and false statement statutes that extend to non-government health benefit programs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• HIPAA, as amended by the Health Information Technology for Economic and Clinical Health Act of 2009 ("***HITECH***"), imposes criminal and civil liability for knowingly and willfully executing a scheme to defraud any healthcare benefit program, or knowingly and willfully falsifying, concealing or covering up a material fact or making any materially false statement in connection with the delivery of or payment for healthcare benefits, items or services. In addition, HIPAA, as amended by HITECH, and their respective implementing regulations impose obligations, including mandatory contractual terms, on covered healthcare providers, health plans, as well as their business associates, with respect to safeguarding the privacy, security and transmission of individually identifiable health information. The Physician Payment Sunshine Act, implemented as the Open Payments program, requires manufacturers of certain products reimbursed by Medicare, Medicaid, or the Children's Health Insurance Program to track and report to the federal government payments and transfers of value that they make to physicians and teaching hospitals, certain other healthcare professionals beginning in 2022, group purchasing organizations, and ownership interests held by physicians and their families, and provides for public disclosures of these data. Manufacturers are required to submit annual reports to the government and failure to do so may result in civil monetary penalties for all payments, transfers of value and ownership or investment interests not reported in an annual submission, and may result in liability under other federal laws and regulations.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Many states have adopted laws and regulations analogous to the federal laws cited above, including state anti-kickback and false claims laws, which may apply to items or services reimbursed under Medicaid and other state programs or, in several states, regardless of the payer. Several states have enacted legislation requiring medical device companies to, among other things, establish marketing compliance programs; file periodic reports with the state, including reports on gifts and payments to individual health care providers; make periodic public disclosures on sales, marketing, pricing, clinical trials and other activities; and/or register their sales representatives. Some states prohibit specified sales and marketing practices, including the provision of gifts, meals, or other items to certain health care providers.

Efforts to ensure that our business arrangements with third parties will comply with applicable healthcare laws and regulations involve substantial costs. Additionally, it is possible that governmental authorities will conclude that our business practices may not comply with current or future statutes, regulations or case law involving applicable fraud and abuse or other healthcare laws and regulations. If our operations are found to be in violation of any of these laws or any other governmental regulations that may apply to us, we may be subject to significant civil, criminal and administrative penalties, damages, fines, exclusion from government funded healthcare programs, such as Medicare and Medicaid, and the curtailment or restructuring of our operations. Exclusion, suspension and debarment from government funded healthcare programs would significantly impact our ability to commercialize, sell or distribute any product. If any of the physicians or other providers or entities with whom we expect to do business are found not to be in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs.

***Changes in laws or regulations relating to data protection, or any actual or perceived failure by us to comply with such laws and regulations or our privacy policies, could materially and adversely affect our business or could lead to government enforcement actions and significant penalties against us, and adversely impact our operating results.***

We may receive health information and other highly sensitive or confidential information and data of patients and other third parties, which we may compile and analyze. Collection and use of this data might raise privacy and data protection concerns, which could negatively impact our business. There are numerous federal, state and international laws and regulations regarding privacy, data protection, information security, and the collection, storing, sharing, use, processing, transfer, disclosure, and protection of personal information and other data, and the scope of such laws and regulations may change, be subject to differing interpretations, and may be inconsistent among countries and regions we intend to operate in (e.g., the U.S., the European Union and Israel), or conflict with other laws and regulations. The regulatory framework for privacy and data protection worldwide is, and is likely to remain for the foreseeable future, uncertain and complex, and this or other actual or alleged obligations may be interpreted and applied in a manner that we may not anticipate or that is inconsistent from one jurisdiction to another and may conflict with other rules or practices including ours. Further, any significant change to applicable laws, regulations, or industry practices regarding the collection, use, retention, security, or disclosure of data, or their interpretation, or any changes regarding the manner in which the consent of relevant users for the collection, use, retention, or disclosure of such data must be obtained, could increase our costs and require us to modify our services and candidate products, possibly in a material manner, which we may be unable to complete, and may limit our ability to store and process patients' data or develop new services and features.

In particular, we will be subject to U.S. data protection laws and regulations (i.e., laws and regulations that address privacy and data security) at both the federal and state levels. The legislative and regulatory landscape for data protection continues

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

to evolve, and in recent years there has been an increasing focus on privacy and data security issues. Numerous federal and state laws, including state data breach notification laws, state health information privacy laws, and federal and state consumer protection laws, govern the collection, use, and disclosure of health-related and other personal information. Failure to comply with such laws and regulations could result in government enforcement actions and create liability for us (including the imposition of significant civil or criminal penalties), private litigation and/or adverse publicity that could negatively affect our business. For instance, California enacted the CCPA on June 28, 2018, which took effect on January 1, 2020. The CCPA creates individual privacy rights for California consumers and increases the privacy and security obligations of entities handling certain personal data. The CCPA provides for civil penalties for violations, as well as a private right of action for data breaches that is expected to increase data breach litigation. The CCPA may increase our compliance costs and potential liability, and many similar laws have been proposed at the federal level and in other states.

In addition, we expect to obtain health information that is subject to privacy and security requirements under HITECH and its implementing regulations. The privacy standards and security standards under HIPAA establish a set of standards for the protection of individually identifiable health information by health plans, health care clearinghouses and certain health care providers, (collectively referred to as "***Covered Entities***"), and the business associates with whom Covered Entities enter into service relationships pursuant to which individually identifiable health information may be exchanged. Notably, whereas HIPAA previously directly regulated only Covered Entities, HITECH makes certain of HIPAA's privacy and security standards also directly applicable to Covered Entities' business associates. As a result, both Covered Entities and business associates are now subject to significant civil and criminal penalties for failure to comply with privacy standards and security standards. As part of our normal operations, we expect to collect, process and retain personal identifying information regarding patients, including as a business associate of Covered Entities, so we expect to be subject to HIPAA, including changes implemented through HITECH, and we could be subject to criminal penalties if we knowingly obtain or disclose individually identifiable health information in a manner that is not authorized or permitted by HIPAA. A data breach affecting sensitive personal information, including health information, also could result in significant legal and financial exposure and reputational damages that could potentially have an adverse effect on our business.

HIPAA requires Covered Entities (like many of our potential customers) and business associates, like us, to develop and maintain policies and procedures with respect to protected health information that is used or disclosed, including the adoption of administrative, physical and technical safeguards to protect such information. HITECH expands the notification requirement for breaches of patient-identifiable health information, restricts certain disclosures and sales of patient-identifiable health information and provides for civil monetary penalties for HIPAA violations. HITECH also increased the civil and criminal penalties that may be imposed against Covered Entities and business associates and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce HIPAA and its implementing regulations and seek attorney's fees and costs associated with pursuing federal civil actions. Additionally, certain states have adopted comparable privacy and security laws and regulations, some of which may be more stringent than HIPAA.

Internationally, many jurisdictions have or are considering enacting privacy or data protection laws or regulations relating to the collection, use, storage, transfer, disclosure and/or other processing of personal data, as well as certification requirements for the hosting of health data specifically. Such laws and regulations may include data hosting, data residency or data localization requirements (which generally require that certain types of data collected within a certain country be stored and processed within that country), data export restrictions, international transfer laws (which prohibit or impose conditions upon the transfer of such data from one country to another), or may require companies to implement privacy or data protection and security policies, enable users to access, correct and delete personal data stored or maintained by such companies, inform individuals of security breaches that affect their personal data or obtain individuals' consent to use their personal data. For example, European legislators adopted the GDPR, which became effective on May 25, 2018, and are now in the process of finalizing the ePrivacy Regulation to replace the European ePrivacy Directive (Directive 2002/58/EC as amended by Directive 2009/136/EC). The GDPR, supplemented by national laws and further implemented through binding guidance from the European Data Protection Board, imposes more stringent European Union data protection requirements and provides for significant penalties for noncompliance. Further, the United Kingdom's initiating a process to leave the European Union has created uncertainty with regard to the regulation of data protection in the United Kingdom. In particular, the United Kingdom has brought the GDPR into domestic law with the Data Protection Act of 2018 which will remain in force, even if and when the United Kingdom leaves the European Union.

Virtually every jurisdiction in which we expect to operate has established its own data security and privacy legal framework with which we must, and our target customers will need to, comply, including the rules and regulation mentioned above. We may also need to comply with varying and possibly conflicting privacy laws and regulations in other jurisdictions. As a result, we could face regulatory actions, including significant fines or penalties, adverse publicity and possible loss of business.

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

In addition, there are ongoing public policy discussions regarding whether the standards for de-identified, anonymous or pseudonymized health information are sufficient to adequately protect patient privacy. These discussions may lead to further restrictions on the use or disclosure of such information. We use a third party service provider to de-identify PHI that parties with which we work receive and may make available to us. There can be no assurance that the policy initiatives or future initiatives will not adversely affect our ability to access and use data or to develop or market current or future services, or that the third party service providers that we use to de-identify PHI will do so in a manner that is deemed compliant with any regulatory standards that currently exist or are developed in the future. There is also a risk that the third parties that license us data and enable us to receive de-identified PHI may fail to properly de-identify PHI under HIPAA or personal data under applicable state or other privacy laws, some of which may impose different standards for de- identification than those required by HIPAA. Furthermore, if we are unable to secure these rights to de-identified information or because of any future changes to HIPAA or other applicable laws, we may face limitations on the use of PHI and our ability to use de-identified information that could negatively affect the scope of our product and service offering as well as impair our ability to provide upgrades and enhancements to our services.

While we are preparing to implement various measures intended to enable us to comply with applicable privacy or data protection laws, regulations and contractual obligations, these measures may not always be effective and do not guarantee compliance. Any failure or perceived failure by us to comply with our contractual or legal obligations or regulatory requirements relating to privacy, data protection, or information security may result in governmental investigations or enforcement actions, litigation, claims, or public statements against us by consumer advocacy groups or others and could result in significant liability, cause our customers, partners or patients to lose trust in us, and otherwise materially and adversely affect our reputation and business. Furthermore, the costs of compliance with, and other burdens imposed by, the laws, regulations, and policies that are applicable to the businesses of our customers or partners may limit the adoption and use of, and reduce the overall demand for, our products and services. Additionally, if third parties we work with violate applicable laws, regulations, or agreements, such violations may put the data we have received at risk, could result in governmental investigations or enforcement actions, fines, litigation, claims, or public statements against us by consumer advocacy groups or others and could result in significant liability, cause our customers, partners or patients to lose trust in us, and otherwise materially and adversely affect our reputation and business. Further, public scrutiny of, or complaints about, technology companies or their data handling or data protection practices, even if unrelated to our business, industry or operations, may lead to increased scrutiny of technology companies, including us, and may cause government agencies to enact additional regulatory requirements, or to modify their enforcement or investigation activities, which may increase our costs and risks.

***Any restrictions on our ability to obtain or use data could harm our business.***

Our business processes personal data, including some data related to health. When conducting clinical trials, we face risks associated with collecting trial participants' data, especially health data, in a manner consistent with applicable laws and regulations. Any errors or defects in any third-party data or other technology could result in errors in our existing and future solutions that could harm our business and damage our reputation and cause losses in revenue, and we could be required to spend significant amounts of additional resources to fix any problems.

We may also face headwinds with limitations on the use of data in current customer contracts. We are currently evaluating those limitations and may need to renegotiate current contracts and negotiate future contracts to allow broader use of data to launch this initiative. Also, healthcare regulations concerning personal health information, including but not limited to HIPAA, HITECH, 42 CFR Part II, and their State law equivalents such as the CCPA, as recently amended and expanded by the California Privacy Rights Act (the "***CPRA***"), could have a significant effect on the manner in which we must handle healthcare related data, and the costs of complying with such standards could be significant.

***If we do not obtain and maintain international regulatory registrations, clearances or approvals for our products, we will be unable to market and sell our products outside of the United States.***

Sales of our products outside of the United States are subject to foreign regulatory requirements that vary widely from country to country. Approval procedures vary among countries and can involve additional testing. The time required to obtain approval outside of the United States may differ substantially from that required to obtain FDA approval. In addition, the FDA regulates exports of medical devices from the United States. While the regulations of some countries may not impose barriers to marketing and selling our products or only require notification, others require that we obtain the clearance or approval of a specified regulatory body. Complying with foreign regulatory requirements, including obtaining registrations, clearances or approvals, can be expensive and time-consuming, and we may not receive regulatory clearances or approvals in each country in which we plan to market our products or we may be unable to do so on a timely basis. The time required to obtain registrations, clearances or approvals, if required by other countries, may be longer than that required for FDA clearance or approval, and requirements for such registrations, clearances or approvals may significantly

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

differ from FDA requirements. If we modify our products, we may need to apply for additional regulatory clearances or approvals before we are permitted to sell the modified product. In addition, we may not continue to meet the quality and safety standards required to maintain the authorizations that we have received. If we are unable to maintain our authorizations in a particular country, we will no longer be able to sell the applicable product in that country.

Regulatory clearance or approval by the FDA does not ensure registration, clearance or approval by regulatory authorities in other countries, and registration, clearance or approval by one or more foreign regulatory authorities does not ensure registration, clearance or approval by regulatory authorities in other foreign countries or by the FDA. However, a failure or delay in obtaining registration or regulatory clearance or approval in one country may have a negative effect on the regulatory process in others.

***Legislative or regulatory reforms in the United States or the EU may make it more difficult and costly for us to obtain regulatory clearances or approvals for our products or to manufacture, market or distribute our products after clearance or approval is obtained.***

From time to time, legislation is drafted and introduced in Congress that could significantly change the statutory provisions governing the regulation of medical devices. In addition, the FDA may change its clearance and approval policies, adopt additional regulations or revise existing regulations, or take other actions, which may prevent or delay approval or clearance of our future products under development or impact our ability to modify our currently cleared products on a timely basis. Over the last several years, the FDA has proposed reforms to its 510(k) clearance process, and such proposals could include increased requirements for clinical data and a longer review period, or could make it more difficult for manufacturers to utilize the 510(k) clearance process for their products. For example, in November 2018, FDA officials announced forthcoming steps that the FDA intends to take to modernize the premarket notification pathway under Section 510(k) of the FDCA. Among other things, the FDA announced that it planned to develop proposals to drive manufacturers utilizing the 510(k) pathway toward the use of newer predicates. These proposals included plans to potentially sunset certain older devices that were used as predicates under the 510(k) clearance pathway, and to potentially publish a list of devices that have been cleared on the basis of demonstrated substantial equivalence to predicate devices that are more than 10 years old. In May 2019, the FDA solicited public feedback on these proposals. The FDA requested public feedback on whether it should consider certain actions that might require new authority, such as whether to sunset certain older devices that were used as predicates under the 510(k) clearance pathway. These proposals have not yet been finalized or adopted, and the FDA may work with Congress to implement such proposals through legislation. Accordingly, it is unclear the extent to which any proposals, if adopted, could impose additional regulatory requirements on us that could delay our ability to obtain new 510(k) clearances, increase the costs of compliance, or restrict our ability to maintain our current clearances, or otherwise create competition that may negatively affect our business.

More recently, in September 2019, the FDA finalized guidance describing an optional "safety and performance based" premarket review pathway for manufacturers of "certain, well-understood device types" to demonstrate substantial equivalence under the 510(k) clearance pathway by showing that such device meets objective safety and performance criteria established by the FDA, thereby obviating the need for manufacturers to compare the safety and performance of their medical devices to specific predicate devices in the clearance process. The FDA intends to develop and maintain a list device types appropriate for the "safety and performance based" pathway and will continue to develop product-specific guidance documents that identify the performance criteria for each such device type, as well as the testing methods recommended in the guidance documents, where feasible. The FDA may establish performance criteria for classes of devices for which we or our competitors seek or currently have received clearance, and it is unclear the extent to which such performance standards, if established, could impact our ability to obtain new 510(k) clearances or otherwise create competition that may negatively affect our business.

In addition, FDA regulations and guidance are often revised or reinterpreted by the FDA in ways that may significantly affect our business and our products. Any new statutes, regulations or revisions or reinterpretations of existing regulations may impose additional costs or lengthen review times of any future products or make it more difficult to obtain clearance or approval for, manufacture, market or distribute our products. We cannot determine what effect changes in regulations, statutes, legal interpretation or policies, when and if promulgated, enacted or adopted may have on our business in the future. Such changes could, among other things, require: additional testing prior to obtaining clearance or approval; changes to manufacturing methods; recall, replacement or discontinuance of our products; or additional record keeping.

The FDA's and other regulatory authorities' policies may change and additional government regulations may be promulgated that could prevent, limit or delay regulatory clearance or approval of our future products. We cannot predict the likelihood, nature or extent of government regulation that may arise from future legislation or administrative action, either in the United States or abroad. If we are slow or unable to adapt to changes in existing requirements or the adoption

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

of new requirements or policies, or if we are not able to maintain regulatory compliance, we may lose any marketing approval or clearance that we may have obtained and we may not achieve or sustain profitability.

On April 5, 2017, the European Parliament passed the MDR (Regulation 2017/745), which repeals and replaces the EU Medical Devices Directive. Unlike directives, which must be implemented into the national laws of the EEA Member States, the regulations would be directly applicable, i.e., without the need for adoption of EEA member state laws implementing them, in all EEA Member States and are intended to eliminate current differences in the regulation of medical devices among EEA Member States. The MDR, among other things, is intended to establish a uniform, transparent, predictable and sustainable regulatory framework across the EEA for medical devices and ensure a high level of safety and health while supporting innovation.

The MDR become applicable three years after publication (in 2020). The new regulations will, among other things:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• strengthen the rules on placing devices on the market and reinforce surveillance once they are available;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• establish explicit provisions on manufacturers' responsibilities for follow-up regarding the quality, performance and safety of devices placed on the market;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• improve the traceability of medical devices throughout the supply chain to the end-user or patient through a unique identification number;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• set up a central database to provide patients, healthcare professionals and the public with comprehensive information on products available in the EU; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• strengthened rules for the assessment of certain high-risk devices, which may have to undergo an additional check by experts before they are placed on the market.

These modifications may have an effect on the way we conduct our business in the EEA.

***Healthcare reform laws could adversely affect our products and financial condition.***

During the past several years, the U.S. healthcare industry has been subject to an increase in governmental regulation at both the federal and state levels. Efforts to control healthcare costs, including limiting access to care, alternative delivery models and changes in the methods used to determine reimbursement scenarios and rates, are ongoing at the federal and state government levels.

In March 2010, former President Obama signed into law the ACA, which included measures that significantly changed the way healthcare is financed by both governmental and private insurers. While a primary goal of these healthcare reform efforts was to expand coverage to more individuals, it also involved additional regulatory mandates and other measures designed to constrain medical costs. The ACA significantly impacts the medical device industry. Among other things, the ACA:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• imposes an annual excise tax of 2.3% on any entity that manufactures or imports medical devices offered for sale in the United States, which, through a series of legislative amendments, was suspended, effective January 1, 2016 and subsequently repealed altogether on December 20, 2019;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• establishes a new Patient-Centered Outcomes Research Institute to oversee and identify priorities in comparative clinical effectiveness research in an effort to coordinate and develop such research; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• implements Medicare payment system reforms including a national pilot program on payment bundling to encourage hospitals, physicians and other providers to improve the coordination, quality and efficiency of certain healthcare services through bundled payment models.

In addition, the ACA and related healthcare reform laws, regulations and initiatives have significantly increased regulation of managed care plans and decreased reimbursement under Medicare managed care. Moreover, to alleviate budget shortfalls, states have reduced or frozen payments to Medicaid managed care plans. We cannot accurately predict the complete impact of these healthcare reform initiatives, but they could lead to a decreased demand for medical devices and other outcomes that could adversely impact our business and financial results.

Some of the provisions of the ACA have yet to be fully implemented, and certain provisions have been subject to judicial and congressional challenges. In addition, there have been efforts by the Trump administration to repeal or replace certain aspects of the ACA and to alter the implementation of the ACA and related laws. For example, the TCJA enacted on

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

December 22, 2017, eliminated the shared responsibility payment for individuals who fail to maintain minimum essential coverage under Section 5000A of the Internal Revenue Code of 1986, commonly referred to as the "individual mandate," effective January 1, 2019. On December 14, 2018, a U.S. District Court Judge in the Northern District of Texas, or the Texas District Court Judge, ruled that the individual mandate is a critical and inseverable feature of the ACA, and therefore, because it was repealed as part of the Tax Cuts and Jobs Act, the remaining provisions of the ACA are invalid as well. This decision was subsequently appealed, and on December 18, 2019, the U.S. Court of Appeals for the Fifth Circuit affirmed the decision of the district court that the individual mandate, as amended by the TCJA, was unconstitutional. The Fifth Circuit remanded the case to the district court to consider a remedy, including to consider and explain which provisions of the ACA are inseverable and invalid. It is unclear how this litigation, including all future hearings and appeals, and other efforts to challenge, repeal or replace the ACA, or portions thereof, will affect our future products or our business. It is possible that the ACA, as currently enacted or as it may be amended in the future, and other healthcare reform measures that may be adopted in the future, could have an adverse effect on our industry generally and on our ability to commercialize our future products and achieve profitability.

***Disruptions at the FDA and other government agencies caused by funding shortages or global health concerns could hinder their ability to hire, retain or deploy key leadership and other personnel, or otherwise prevent new or modified products from being developed, cleared or approved or commercialized in a timely manner or at all, which could negatively impact our business.***

The ability of the FDA to review and clear or approve new products can be affected by a variety of factors, including government budget and funding levels, statutory, regulatory, and policy changes, the FDA's ability to hire and retain key personnel and accept the payment of user fees, and other events that may otherwise affect the FDA's ability to perform routine functions. Average review times at the FDA have fluctuated in recent years as a result. In addition, government funding of other government agencies that fund research and development activities is subject to the political process, which is inherently fluid and unpredictable.

Disruptions at the FDA and other agencies may also slow the time necessary for new medical devices or modifications to cleared or approved medical devices to be reviewed and/or approved by necessary government agencies, which would adversely affect our business. For example, over the last several years, including for 35 days beginning on December 22, 2018, the U.S. government has shut down several times and certain regulatory agencies, such as the FDA, have had to furlough critical FDA employees and stop critical activities.

Separately, in response to the COVID-19 pandemic, on March 10, 2020 the FDA announced its intention to postpone most inspections of foreign manufacturing facilities, and on March 18, 2020, the FDA temporarily postponed routine surveillance inspections of domestic manufacturing facilities. Subsequently, on July 10, 2020 the FDA announced its intention to resume certain on-site inspections of domestic manufacturing facilities subject to a risk-based prioritization system. The FDA intends to use this risk-based assessment system to identify the categories of regulatory activity that can occur within a given geographic area, ranging from mission critical inspections to resumption of all regulatory activities. Regulatory authorities outside the United States may adopt similar restrictions or other policy measures in response to the COVID-19 pandemic. If a prolonged government shutdown occurs, or if global health concerns continue to prevent the FDA or other regulatory authorities from conducting their regular inspections, reviews, or other regulatory activities, it could significantly impact the ability of the FDA or other regulatory authorities to timely review and process our regulatory submissions, which could have a material adverse effect on our business.

***Consolidation in the U.S. healthcare industry may negatively impact our results of operations.***

In recent years, U.S. healthcare industry participants, including distributors, manufacturers, suppliers, healthcare providers, insurers and pharmacy chains, have consolidated or formed strategic alliances. Consolidations create larger enterprises with greater negotiating power, and also could result in the possible loss of a customer where the combined enterprise selects one distributor from two incumbents. If this consolidation trend continues, it could adversely affect our results of operations.

***Failure to comply with anti-bribery and anti-corruption laws could subject us to penalties and other adverse consequences.***

Since we may operate and sell our products around the world, we will be subject to the United States Foreign Corrupt Practices Act (the "***FCPA***"), the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the United States Travel Act, and other anti-corruption and anti-bribery laws and regulations in the jurisdictions in which we currently or may do business, both domestic and abroad. These laws and regulations generally prohibit improper payments or offers of

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

improper payments to government officials, political parties, or commercial partners for the purpose of obtaining or retaining business or securing an improper business advantage.

Corruption issues pose a risk in every country and jurisdiction, but in many countries, particularly in countries with developing economies, it may be more common for businesses to engage in practices that are prohibited by the FCPA or other applicable laws and regulations, and our activities in these countries pose a heightened risk of unauthorized payments or offers of payments by one of our employees or third-party business partners, representatives, and agents that could be in violation of various laws including the FCPA. The FCPA and other applicable anti-bribery and anti-corruption laws also may hold us liable for acts of corruption and bribery committed by our third-party business partners, representatives, and agents. We and our third-party business partners, representatives, and agents may have direct or indirect interactions with officials and employees of government agencies, or state-owned or affiliated entities and we may be held liable for the corrupt or other illegal activities of our employees or such third parties even if we do not explicitly authorize such activities. The FCPA or other applicable laws and regulations also require that we keep accurate books and records and maintain internal controls and compliance procedures designed to prevent improper payments. While we have implemented policies and procedures to address compliance with such laws, we cannot assure you that our employees or other third parties working on our behalf will not engage in conduct in violation of our policies or applicable law for which we might ultimately be held responsible. Violations of the FCPA and other applicable anti-corruption laws may result in whistleblower complaints, adverse media coverage, investigations, imposition of significant legal fees, loss of export privileges, as well as severe criminal or civil sanctions, including suspension or debarment from U.S. government contracting, and we may be subject to other liabilities and adverse effects on our reputation, which could negatively affect our business, results of operations, financial condition, and growth prospects. In addition, responding to any enforcement action may result in a significant diversion of management's attention and resources and significant legal defense costs and other professional fees. Our exposure for violating these laws increases as our non-U.S. presence expands and as we increase sales and operations in foreign jurisdictions.

***Changes in accounting principles or their application to us could result in unfavorable accounting charges or effects, which could adversely affect our results of operations and growth prospects.***

We prepare our consolidated financial statements in accordance with accounting principles generally accepted in the United States ("***GAAP***"). In particular, we make certain estimates and assumptions related to the adoption and interpretation of these principles including the recognition of our revenue and the accounting of our stock-based compensation expense with respect to our consolidated financial statements. If these assumptions turn out to be incorrect, our financial results could materially differ from our expectations and could be materially adversely affected. A change in any of these principles or guidance, or in their interpretations or application to us, may have a significant effect on our reported results, as well as our processes and related controls, and may retroactively affect previously reported results or our forecasts, which may negatively impact our consolidated financial statements.

***If our judgments or estimates relating to our critical accounting policies are based on assumptions that change or prove to be incorrect, our results of operations could fall below expectations of securities analysts and investors, resulting in a decline in our stock price.***

The preparation of our consolidated financial statements in conformity with GAAP requires management to make judgments, estimates, and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances, as provided in the section titled "*Management's Discussion and Analysis of Financial Condition and Results of Operations*" the results of which form the basis for making judgments about the carrying values of assets, liabilities, and equity, and the amount of revenue and expenses that are not readily apparent from other sources. Our results of operations may be adversely affected if our assumptions change or if actual circumstances differ from those in our assumptions, which could cause our results of operations to fall below the expectations of securities analysts and investors, resulting in a decline in the trading price of our common stock. Significant judgments, estimates, and assumptions used in preparing our consolidated financial statements include, or may in the future include, those related to revenue recognition, stock-based compensation, intangible assets, including goodwill, and income taxes.

***We could be subject to additional tax liabilities.***

We are subject to federal, state, and local income taxes in the US. Determining our provision for income taxes requires significant management judgment, and the ultimate tax outcome may be uncertain. In addition, our provision for income taxes is subject to volatility and could be adversely affected by many factors, including, among other things, changes to our operating or holding structure, changes in the amounts of earnings in jurisdictions with differing statutory tax rates, changes in the valuation of deferred tax assets and liabilities, and changes in U.S. tax laws. Tax authorities may disagree

with our calculation of research and development tax credits, cross-jurisdictional transfer pricing, or other matters and assess additional taxes, interest, or penalties. While we regularly assess the likely outcomes of these examinations to determine the adequacy of our provision for income taxes and we believe that our financial statements reflect adequate reserves to cover any such contingencies, there can be no assurance that the outcomes of such examinations will not have a material impact on our results of operations and cash flows. If tax authorities change applicable tax laws, our overall taxes could increase, and our financial condition or results of operations may be adversely impacted.

**Risks Related to Our Intellectual Property** 

***It is difficult and costly to protect our intellectual property and our proprietary technologies, and we may not be able to ensure their protection.***

We rely upon a combination of patents and trade secrets to protect the intellectual property related to our proprietary technologies. Our success depends significantly on our ability to obtain and maintain intellectual property protection with respect to our technology and products. Patents and other proprietary rights provide uncertain protections, and we may be unable to protect our intellectual property for reasons including those that result from complex factual and legal issues such as those that create uncertainty as to the validity, scope and enforceability of any particular patent that we hold or for which we have applied. As a result, we may be unsuccessful in defending our patents and other proprietary rights against third-party challenges, which could have a material adverse effect on our business.

Our company uses a combination of patents, trademarks and copyrights to protect our intellectual property. Although we currently have active U.S. and European patents and patents pending with the U.S. Patent & Trademark Office and have filed to obtain patent coverage for our technology in the UK, France, Germany, Italy, Netherlands and Spain, there are aspects of the technology for which patent coverage may never be sought or received. Additionally, we may in the future obtain, certain intellectual property related to our technology from third parties, and we cannot be certain that such third parties took the necessary actions to maintain such rights or that the transfer of such rights to us was proper and effective. We may, as a result, be subject to claims challenging the ownership or enforceability of such rights. Furthermore, we may not possess the resources to, or for other reasons may not choose to, pursue patent protection on every invention or in any or every country where we may eventually decide to sell our future products. Our ability to prevent others from making or selling duplicate or similar technologies will be impaired for those technologies with respect to which, and in those countries where, we have no patent protection. In addition, there is no assurance that all potentially relevant prior art relating to our patents and patent applications has been found, which can prevent a patent from issuing from a pending patent application or later invalidate or narrow the scope of an issued patent. Even if patents do successfully issue and even if such patents cover our technology, third parties may challenge their validity, enforceability or scope, which may result in such patents being narrowed, invalidated, or held unenforceable. Any successful challenge to these patents or any other patents owned by or licensed to us could deprive us of rights necessary for the successful commercialization of our technology.

In addition, for patents that do issue based on our applications or future applications, any issued patents may not provide us with any competitive advantages. Competitors may be able to design around our patents and develop products that provide outcomes comparable or superior to ours. Any changes we make to our product or any future products, including designs that may be required for commercialization or that cause them to have what we view as more advantageous properties, may not be covered by patents and patent applications we have licensed or own, and we may be required to file new applications and/or seek other forms of protection for any such altered products if any such protection is available. In addition, the patent prosecution process is expensive, time-consuming and complicated, and we and our current or future licensors, licensees or collaborators may not be able to prepare, file, prosecute and maintain all necessary or desirable patents or patent applications at a reasonable cost or in a timely manner. It is also possible that we or our current or future licensors, licensees or collaborators will fail to identify patentable aspects of inventions before it is too late to obtain patent protection for them. In addition, if we choose to and are able to secure patent protection in countries outside the U.S., the laws of some foreign countries may not protect our intellectual property rights to the same extent as do the laws of the United States. For instance, the legal systems of some countries, including India, China and other developing countries, do not favor the enforcement of patents and other intellectual property rights. This could make it difficult for us to stop the infringement of our patents or the misappropriation of our other intellectual property rights.

Some countries also have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. In addition, some countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of such patent. If we or any of our licensors is forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired.

Changes in either the patent laws or their interpretation in the United States and other countries may diminish our ability to protect our inventions and enforce our intellectual property rights, and more generally could affect the value of our intellectual property. Our efforts to seek patent protection for our technology could be negatively impacted by any such changes, which could have a material adverse effect on our existing patent rights and our ability to protect and enforce our intellectual property in the future. In particular, our ability to stop third parties from making, using, selling, offering to sell or importing products that infringe our intellectual property will depend in part on our success in obtaining and enforcing patent claims that cover our technology, inventions and improvements.

We may come to believe that third parties are infringing on, or otherwise violating, our patents or other proprietary rights. To prevent infringement or unauthorized use, we may need to file infringement and/or misappropriation suits, which are very expensive and time-consuming, could result in meritorious counterclaims against us and would distract management's attention. Also, in an infringement or misappropriation proceeding, a court may decide that one or more of our patents is invalid, unenforceable, or both, in which case third parties may be able to use our technology without paying license fees or royalties. Even if the validity of our patents is upheld, a court may refuse to stop the other party from using the technology at issue on the grounds that the other party's activities are not covered by our patents.

In addition to patents, we rely on trade secrets to protect our technology; however, the policies we use to protect our trade secrets may not be effective in preventing misappropriation of our trade secrets by others. In addition, confidentiality agreements executed by our employees, consultants and advisors may not be enforceable or may not provide meaningful protection for our trade secrets or other proprietary information in the event of unauthorized use or disclosure. Litigating a trade secret claim is expensive and time consuming, and the outcome may be unexpected. In addition, courts outside the United States are sometimes less willing to protect trade secrets. Moreover, our competitors may independently develop knowledge, methods and know-how that allow them to create substantially similar products or services without misappropriating our trade secrets. If we are unable to protect our trade secrets, we may be unable to prevent competitors from using our own inventions and intellectual property to compete against us, and our business may be harmed.

***If we are unable to protect or enforce our patents or other proprietary rights, or if we become subject to claims or litigation alleging infringement of the patents or other proprietary rights of others, our competitiveness and business prospects may be materially damaged.***

Patent and other proprietary rights are essential to our business. Our success depends to a significant degree on our ability to obtain and enforce patents and licenses to patent rights, both in the United States and in other countries. We cannot guarantee that our pending patent applications, or any future patent applications, will result in issued patents, our patents issued or licensed will not be challenged or circumvented by competitors, our patents will not be found to be invalid or the intellectual property rights of others will not prevent us from selling certain products or including key features in our products.

The patent position of a healthcare company is often uncertain and involves complex legal and factual questions. Significant litigation concerning patents and products is pervasive in our industry. Patent claims include challenges to the coverage and validity of our patents on products or processes as well as allegations that our products infringe patents held by competitors or other third parties. An unfavorable litigation outcome in any of these types of cases could result in a loss of patent protection or the ability to market products, which could lead to a significant loss of sales, or otherwise materially affect our business, results of operations, financial condition and cash flows. We also rely on trademarks, copyrights, trade secrets and know-how to develop, maintain and strengthen our competitive positions. Third parties may know, discover or independently develop equivalent proprietary information or techniques, or they may gain access to our trade secrets or publicly disclose our trade secrets.

Although our employees, consultants, parties to collaboration agreements and other business partners are generally subject to confidentiality or similar agreements to protect our confidential and proprietary information, these agreements may be breached, and we may not have adequate remedies for any breach. To the extent that our employees, consultants, parties to collaboration agreements and other business partners use intellectual property owned by others in their work for us, disputes may arise as to the rights in related or resulting know-how and inventions.

Furthermore, our intellectual property, proprietary technology and sensitive company data is potentially vulnerable to loss, damage and misappropriation from system malfunction, computer viruses and unauthorized access to our data or misappropriation or misuse thereof by those with permitted access and other events. While we have invested to protect our intellectual property, confidential information and other data, and continue to work diligently in this area, there can be no assurance that our precautionary measures have prevented or will prevent future breakdowns, breaches, cyber incidents or other events. Any of the events referenced above could have a material adverse effect on our reputation, business, results of operations, financial condition and cash flows.

***Patent terms may be inadequate to protect our competitive position on our future products for an adequate amount of time.***

Patents have a limited lifespan. In the United States, if all maintenance fees are timely paid, the natural expiration of a patent is generally 20 years from its earliest U.S. non-provisional filing date. Various extensions may be available, but the life of a patent, and the protection it affords, is limited. Even if patents covering our future products are obtained, once the patent life has expired, we may be open to competition from competitive products.

Given the amount of time required for the development, testing and regulatory review of new products, patents protecting our future products might expire before or shortly after we or our future partners commercialize those products. As a result, our owned and licensed patent portfolio may not provide us with sufficient rights to exclude others from commercializing products similar or identical to ours for a sufficient amount of time, and, as a result, we may not be able to obtain adequate protection from our patent portfolio against competition, in spite of the time and effort invested in the commercialization of our future products.

***Claims that our technology or our future products or the sale or use of our future products infringe the patents or other intellectual property rights of third parties could result in costly litigation or could require substantial time and money to resolve, even if litigation is avoided.***

Because our industry is characterized by competing intellectual property, we may be subject to legal actions for violating the intellectual property rights of others, including claims that former employees, collaborators or third parties have an interest in our patents, trade secrets or other intellectual property. For example, we may have inventorship or ownership disputes arising from conflicting obligations of employees, consultants or others who are involved in developing our technology or our products.

We also may be required to participate in interference, derivation or opposition proceedings that concern disputes regarding priority of inventions disclosed in our patents. Determining whether a product infringes a patent, as well as priority of inventions and other patent-related disputes, involves complex legal and factual issues and the outcome is often uncertain. We have not conducted any significant search of patents issued to third parties, and third-party patents containing claims covering our technology or methods that predate our patents may exist. Because of the number of patents issued and patent applications filed in our technical areas or fields (including some pertaining specifically to medical imaging technologies), our competitors or other third parties may assert that our technology and the methods we employ in the use of products incorporating our technology are covered by United States or foreign patents held by them. In addition, because patent applications can take many years to issue and because publication schedules for pending applications vary by jurisdiction, there may be applications now pending of which we are unaware, and which may result in issued patents that our technology or other future products would infringe. Also, because the claims of published patent applications can change between publication and patent grant, there may be published patent applications that may ultimately issue with claims that we infringe.

As the number of competitors in the market for medical imaging technologies increases, and as the number of patents issued in this area grows, the possibility of patent infringement claims against us increases. Some of our competitors may be able to sustain the costs of complex patent litigation more effectively than we can, including if they have substantially greater resources. Defending against such litigation is costly and time consuming, and would distract our management from our business. In addition, any uncertainties resulting from the initiation and continuation of any litigation could have a material adverse effect on our ability to raise the funds necessary to continue our operations.

In the event that we become subject to a patent infringement or other intellectual property lawsuit and if the relevant patents or other intellectual property were upheld as valid and enforceable and we were found to infringe or violate those rights or the terms of a license to which we are a party, we could be prevented from selling any infringing products of ours unless we could obtain a license or were able to redesign the product to avoid infringement. If we were unable to obtain a license or successfully redesign, we might be prevented from selling our technology or other future products. If we are able to redesign, we may need to invest substantial resources in the redesign process. If there is an allegation or determination that we have infringed the intellectual property rights of a competitor or other person, we may be required to pay damages, or a settlement or ongoing royalties, or we may be required to enter into cross-licenses with our competitors. In any of these circumstances, we may be unable to sell our products at competitive prices or at all, and our business, financial condition, results of operations and prospects could be harmed.

In addition, we may be required to indemnify our customers and distributors against claims relating to the infringement of intellectual property rights of third parties related to our products. Third parties may assert infringement claims against our customers or distributors. These claims may require us to initiate or defend protracted and costly litigation on behalf of our

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

customers or distributors, regardless of the merits of these claims. If any of these claims succeed, we may be forced to pay damages on behalf of our customers or distributors, or may be required to obtain licenses for the products or services they use. If we cannot obtain all necessary licenses on commercially reasonable terms, our distributors may be forced to stop distributing our products or services, and our customers may be forced to stop using our products or services.

Furthermore, because of the substantial amount of discovery required in connection with intellectual property litigation, there is a risk that some of our confidential information could be compromised by disclosure during discovery. There could also be public announcements of the results of hearings, motions or other interim proceedings or developments, which could have a material adverse effect on the price of our common stock. If securities analysts or investors perceive these results to be negative, it could have a material adverse effect on the price of our common stock.

***Obtaining and maintaining patent protection depends on compliance with various procedural, document submission, fee payment and other requirements imposed by governmental patent agencies, and our patent protection could be reduced or eliminated if we or our future licensors do not comply with these requirements.***

Periodic maintenance fees, renewal fees, annuity fees and various other government fees on a patent and patent application are due to be paid to the patent offices and agencies in several stages over the lifetime of the patent and patent application. The U.S. Patent and Trademark Office and various foreign governmental patent agencies require compliance with a number of procedural, documentary, fee payment and other similar provisions during the patent application process. In certain circumstances, we may be required to rely on our licensing partners to take the necessary action to comply with these requirements with respect to patents or other intellectual property they have licensed to us. While an inadvertent lapse can in many cases be cured by payment of a late fee or by other means in accordance with the applicable rules, there are situations in which noncompliance, which could include failure to respond to official actions within prescribed time limits, non-payment of fees and failure to properly legalize and submit formal documents, can result in abandonment or lapse of the patent or patent application, resulting in partial or complete loss of patent rights in the relevant jurisdiction. In such an event, our competitors may be able to enter the market and compete with our products, which would have a material adverse effect on our business.

***We may be subject to claims that our employees, consultants or advisers have wrongfully used or disclosed alleged trade secrets of their former employers or claims asserting ownership of what we regard as our own intellectual property.***

Many of our employees, consultants and advisers, including our senior management, were previously employed at other companies that may have proprietary rights related to our business. Some of these employees, consultants and advisers, including members of our senior management, executed proprietary rights, non-disclosure and non-competition agreements in connection with such previous employment. Although we try to ensure that such individuals do not use the proprietary information or know-how of others in their work for us, we may be subject to claims that we or these employees have used or disclosed intellectual property, including trade secrets or other proprietary information, of any such individual's former employer. We are not aware of any such disclosures, or threatened or pending claims related to these matters, but in the future, litigation may be necessary to defend against such claims. If we fail in defending any such claims, we may lose valuable intellectual property rights or personnel, in addition to possibly paying monetary damages and being enjoined from conducting our business as contemplated. Even if we are successful in defending against such claims, litigation could result in substantial costs and be a distraction to management.

Additionally, a licensor, collaborator, employee, consultant, adviser or other third party may dispute our or our licensor's ownership of certain intellectual property rights. We seek to address these concerns in our contractual agreements; however, we may not have contractual arrangements with the party in question and/or such provisions may not be effective. If these provisions prove to be ineffective, we may not be able to achieve our business objectives. If we or our licensors fail in defending any such claims, we may have to pay monetary damages and may lose valuable intellectual property rights, such as exclusive ownership of, or right to use, intellectual property, which could adversely impact our business, financial condition and results of operations.

***If our trademarks and trade names are not adequately protected, then we may not be able to build name recognition in our markets of interest and our business may be adversely affected.***

Our registered and unregistered trademarks or trade names are valuable assets and may be challenged, infringed, circumvented or declared generic or determined to infringe third party's marks. We may not be able to protect our rights to these trademarks and trade names, which may be necessary to build name recognition among potential collaborators or customers in our markets of interest. At times, competitors may adopt trade names or trademarks similar to ours, thereby impeding our ability to build brand identity and possibly leading to market confusion. In addition, there could be potential trade name or trademark infringement claims brought by owners of other trademarks or trademarks that incorporate

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

variations of our unregistered trademarks or trade names. We have not conducted any registrability studies for possible future trademarks to assess whether such marks would be successfully registered. Over the long term, if we are unable to establish name recognition based on our trademarks and trade names, then we may not be able to compete effectively and our business may be adversely affected. In addition, we may license our trademarks and trade names to third parties, such as distributors. Though these license agreements may provide guidelines for how our trademarks and trade names may be used, a breach of these agreements or misuse of our trademarks and tradenames by our licensees may jeopardize our rights in or diminish the goodwill associated with our trademarks and trade names. Our efforts to enforce or protect our proprietary rights related to trademarks, trade names, trade secrets, domain names, copyrights or other intellectual property may be ineffective and could result in substantial costs and diversion of resources and adversely affect our competitive position, business, financial condition, results of operations and prospects.

***Our rights to develop and commercialize our products may be subject to the terms and conditions of licenses and sublicenses granted to us by third parties.***

We rely on licenses and sublicenses to certain patent rights and other intellectual property from third parties that are important or necessary to the development of our products, including the software modules and cloud software that are integrated into the QT Breast Scanner and products and services. These and other licenses may not provide exclusive rights to use such intellectual property in all relevant fields of use and in all territories in which we may wish to develop or commercialize our products and the underlying patents may fail to provide the intended exclusivity. As a result, we may not be able to prevent competitors from developing and commercializing competitive products in the markets that we hope to address. Moreover, we would not own at least some of the underlying intellectual property rights related to these products, and as a result our rights would be subject to the continuation and compliance with the terms of those agreements. If such in-licenses were terminated, competitors would have the freedom to develop, seek regulatory approval of, and to market, products similar or identical to ours.

In addition, these license agreements may not grant us the right to control the preparation, filing, prosecution or maintenance of patents and patent applications covering our products. Therefore, we cannot be certain that these patents and patent applications will be prepared, filed, prosecuted or maintained in a manner consistent with the best interests of our business. If our current or future licensing partners fail to file, prosecute or maintain such patents, including the payment of applicable fees, or otherwise lose rights to those patents or patent applications, the intellectual property we have licensed or exclusivity we have been granted may be reduced or eliminated, and our right to develop and commercialize any of our future products that are subject of such licensed rights, and our ability to prevent competitors from developing or commercializing such products, could be adversely affected. In addition, even where we have the right to control patent prosecution and maintenance of patents and patent applications we have licensed from third parties, we may still be adversely affected or prejudiced by actions or inactions of our licensees, our licensors and their counsel that took place prior to the date upon which we assumed control over patent prosecution.

Pursuant to the terms of such license agreements, the licensors may also have the right to control enforcement of our licensed patents or defense of any claims asserting the invalidity or unenforceability of these patents. Even if we are permitted to pursue the enforcement or defense of our licensed patents, we may require the cooperation of our future licensors or collaboration partners and any other applicable patent owners and we cannot be certain that such cooperation will be provided to us. We also cannot be certain that our licensors will allocate sufficient resources or prioritize their or our enforcement of such patents or defense of such claims to protect our interests in the licensed patents. Even if we are not a party to these legal actions, an adverse outcome could harm our business because it might prevent us from continuing to license intellectual property that we may need to operate our business. If we lose any of our licensed intellectual property, our right to develop and commercialize any of our products that are subject of such licensed rights could be adversely affected.

In addition, our future licensors may rely on third-party consultants or collaborators or on funds from third parties such that our licensors are not the sole and exclusive owners of the patents we in-license. If other third parties have ownership rights to our in-licensed patents, they may be able to license such patents to our competitors, and our competitors could market competing products and technologies. In addition, if our licensors have not obtained adequate rights from these third parties, we may need to obtain additional rights from these third parties or we could be prevented from developing and commercializing the related products. This could have a material adverse effect on our competitive position, business, financial conditions, results of operations and prospects.

In spite of our best efforts, our licensors might conclude that we have materially breached our license agreements and might therefore terminate the license agreements, in which event we may have to cease developing, manufacturing or marketing any product covered by these agreements and we may face other additional penalties or be required to grant our licensors additional rights. In addition, we may seek to obtain additional licenses from our licensors and, in connection with

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

obtaining such licenses, we may agree to amend our existing licenses in a manner that may be more favorable to the licensors, including by agreeing to terms that could enable third parties (potentially including our competitors) to receive licenses to a portion of the intellectual property that is subject to our existing licenses. Any of these events could have a material adverse effect on our competitive position, business, financial conditions, results of operations and prospects.

***We may be required to pay certain milestones and royalties and fulfill other obligations under our license agreements with third-party licensors.***

We may be required to pay milestones and royalties related to our development or commercialization activities of our products utilizing the technologies licensed or sublicensed from third parties under license agreements we may enter into with them. These payments could adversely affect our overall profitability related to any future products that we may seek to develop or commercialize. In order to maintain our license rights under our license agreements, we may need to meet certain specified milestones or fulfill certain obligations, including to devote a certain amount of resources, in the development of our products. Failure to satisfy such obligations could result in the termination of our rights under such agreements.

***If we choose to license our technology to third parties, this could result in disputes or otherwise limit our future operations.***

We may also in the future, as one of our strategies, deploy our technology into the market and license patents and other intellectual proprietary rights to third parties. Disputes with our licensees may arise, including regarding the scope and content of these licenses. Additionally, a licensee may use our intellectual property without our permission, dispute our ownership of certain intellectual property rights or argue that our intellectual property does not cover our product. Regardless of whether we pursue legal action to enforce any such dispute, a dispute with a licensee or customer over intellectual property rights may damage our relationship with that licensee or customer and may also harm our reputation in the industry. Our ability to expand into additional fields with our technologies also may be restricted by licenses or other rights we may grant to third parties in the future, including if the licenses are exclusive, the licensee is assigned ownership of intellectual property that we develop or rights of first negotiation or refusal are granted.

***We may in the future be subject to intellectual property rights claims, which are extremely costly to defend, could require us to pay significant damages and could limit our ability to use certain technologies.***

Our success and ability to compete also depends in part on our ability to operate without infringing, misappropriating or otherwise violating the intellectual property or other proprietary rights of third parties. Companies in the technology industries, including some of our current and potential competitors, own large numbers of patents, copyrights, trademarks, and trade secrets and frequently pursue litigation based on allegations of infringement, misappropriation, or other violations of intellectual property rights. In addition, many of these companies have the capability to dedicate substantial resources to enforce their intellectual property rights and to defend claims that may be brought against them. Such litigation also may involve non-practicing patent assertion entities or companies who use their patents to extract license fees by threatening costly litigation or that have minimal operations or relevant product revenue and against whom our patents may provide little or no deterrence or protection. While we have not received any notices to date, we may receive notices in the future that claim we have infringed, misappropriated, misused, or otherwise violated other parties' intellectual property rights, and, to the extent we become exposed to greater visibility, we face a higher risk of being the subject of intellectual property infringement, misappropriation or other violation claims, which is not uncommon with respect to software technologies in particular. There may be third-party intellectual property rights, including issued patents or pending patent applications, that cover significant aspects of our technologies, or business methods. There may also be third-party intellectual property rights, including trademark registrations and pending applications, that cover the goods and services that we offer in certain regions. We may also be exposed to increased risk of being the subject of intellectual property infringement, misappropriation, or other violation claims as a result of acquisitions and our incorporation of open source and other third-party software into, or new branding for, our software, as, among other things, we have a lower level of visibility into the development process with respect to such technology or the care taken to safeguard against infringement, misappropriation, or other violation risks. In addition, former employers of our current, former, or future employees may assert claims that such employees have improperly disclosed to us confidential or proprietary information of these former employers. Any intellectual property claims, with or without merit, are difficult to predict, could be very time-consuming and expensive to settle or litigate, could divert our management's attention and other resources, and may not be covered by the insurance that we carry. These claims could subject us to significant liability for damages, potentially including treble damages if we are found to have willfully infringed a third party's intellectual property rights. These claims could also result in our having to stop using technology, branding or marks found to be in violation of a third party's rights and any necessary rebranding could result in the loss of goodwill. We could be required to seek a license for the intellectual property, which may not be available on commercially reasonable terms or at all. Even if a license were available, we could be required to pay

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

significant royalties, which would increase our expenses. As a result, we could be required to develop alternative non-infringing technology, branding or marks, which could require significant effort and expense. If we cannot license rights or develop technology for any infringing aspect of our business, we would be forced to limit or stop sales of one or more of our software or features, we could lose existing customers, and we may be unable to compete effectively. Any of these results would harm our business, financial condition, and results of operations.

Further, certain of our agreements with customers and other third parties may include indemnification provisions under which we agree to indemnify them for losses suffered or incurred as a result of third-party claims of intellectual property infringement, misappropriation, or other violations of intellectual property rights, damages caused by us to property or persons, or other liabilities relating to or arising from our software, services, or other contractual obligations. Large indemnity payments could harm our business, financial condition, and results of operations. Any dispute with a customer with respect to such obligations could have adverse effects on our relationship with that customer and other existing customers and new customers and harm our business and results of operations.

**Risks Related to Our Management** 

***We are highly dependent on key members of our executive management team. Our inability to retain these individuals could impede our business plan and growth strategies, which could have a negative impact on our business and the value of your investment.***

Our ability to implement our business plan depends on the continued services of key members of our senior management. In particular, and to a critical extent, we are dependent on the continued efforts and services of the members of management named in the "*Management*" section. If we lose the services of such key members of our management team, we would likely be forced to expend significant time and money in the pursuit of replacement individuals, which may result in a delay in the implementation of our business plan and plan of operations. We may not be able to find satisfactory replacements on terms that would not be unduly expensive or burdensome to us. We do not currently carry a key-man life insurance policy that would assist us in recouping our costs in the event of the death or disability of a member of our management team. The loss of members of our management team, or our inability to attract or retain other qualified individuals, could have a material adverse effect on our business, results of operations and financial condition.

***Our management team has limited experience managing a public company.***

Other than our Chief Executive Officer, most members of our management team have limited or no experience managing a publicly traded company, interacting with public company investors and complying with the increasingly complex laws pertaining to public companies in the United States. Our management team may not successfully or efficiently manage our transition to being a public company subject to significant regulatory oversight and reporting obligations under the U.S. federal securities laws and the continuous scrutiny of securities analysts and investors. Their limited experience in dealing with the increasingly complex laws pertaining to public companies could be a significant disadvantage in that it is likely that an increasing amount of their time may be devoted to these activities which will result in less time being devoted to the management and growth of the Company. Thus, the Company may not have adequate personnel with the appropriate level of knowledge, experience, and training in the accounting policies, practices or internal controls over financial reporting required of public companies in the United States. The development and implementation of the standards and controls necessary for the Company to achieve the level of accounting standards required of a public company in the United States may require costs greater than expected. It is possible that the Company will be required to expand its employee base and hire additional employees to support its operations as a public company which will increase its operating costs in future periods. These new obligations and constituents will require significant attention from our senior management and could divert their attention away from the day-to-day management of our business, which could adversely affect our business, financial condition, results of operations and prospects.

***Certain of our directors and/or officers may have interests that compete with ours.***

Certain of our directors and/or officers currently own, operate and manage other entities, which may have similar or different objectives than ours. Such activities could detract from the time these people have to allocate to our affairs.

***Our lack of adequate directors and officers insurance may also make it difficult for us to retain and attract talented and skilled directors and officers.***

In the future we may be subject to litigation, including potential class action and shareholder derivative actions. Risks associated with legal liability are difficult to assess and quantify, and their existence and magnitude can remain unknown for significant periods of time. While we do have directors and officers ("***D&O***") insurance it may not be sufficient in the case of litigation.

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

Moreover, the cost of maintaining adequate D&O insurance coverage may increase significantly in the future, our operating results could be materially adversely affected. Likewise, if any of our current D&O insurance coverage should become unavailable to us or become economically impractical, we may need to decrease our coverage limits or increase our self-insured retention or we may be unable to renew such insurance at all. If we incur liabilities that exceed our coverage or incur liabilities not covered by our insurance, we would have to self-fund any indemnification amounts owed to our directors and officers and employees in which case our results of operations and financial condition could be materially adversely affected. Additionally, a lack of D&O insurance may make it difficult for us to retain and attract talented and skilled directors and officers to serve our company, which could adversely affect our business.

**Risks Related to Our Ownership of Common Stock and Other Securities** 

***The price of shares of common stock may be volatile or may decline regardless of our operating performance. You may lose some or all of your investment.***

The trading price of shares of our common stock is likely to be volatile. The stock market recently has experienced extreme volatility. This volatility often has been unrelated or disproportionate to the operating performance of particular companies. You may not be able to resell your shares at an attractive price due to a number of factors such as those listed in "*Risks Related to Our Business, Financial Condition, and Need for Additional Capital*" and the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• our operating and financial performance and prospects;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• quarterly or annual earnings or those of other companies in our industry compared to market expectations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• conditions that impact demand for our products and/or services;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• future announcements concerning our business, our clients' businesses or our competitors' businesses;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the public's reaction to our press releases, other public announcements and filings with the SEC;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the market's reaction to our reduced disclosure and other requirements as a result of being an "emerging growth company" under the Jumpstart Our Business Startups Act of 2012 ("JOBS Act");

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the size of our public float;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• coverage by or changes in financial estimates by securities analysts or failure to meet their expectations;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• market and industry perception of our success, or lack thereof, in pursuing our growth strategy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• strategic actions by us or our competitors, such as acquisitions or restructurings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in laws or regulations which adversely affect our industry or us;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• privacy and data protection laws, privacy or data breaches, or the loss of data;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in accounting standards, policies, guidance, interpretations or principles;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in senior management or key personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• issuances, exchanges or sales, or expected issuances, exchanges or sales of our capital stock;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in our dividend policy;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• adverse resolution of new or pending litigation against us; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in general market, economic and political conditions in the United States and global economies or financial markets, including those resulting from natural disasters, terrorist attacks, acts of war and responses to such events.

These broad market and industry factors may materially reduce the market price of shares of common stock, regardless of our operating performance. In addition, price volatility may be greater if the public float and trading volume of common stock is low. As a result, you may suffer a loss on your investment.

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

In the past, following periods of market volatility, stockholders have instituted securities class action litigation. If we were involved in securities litigation, it could have a substantial cost and divert resources and the attention of executive management from our business regardless of the outcome of such litigation.

***We do not intend to pay dividends on shares of common stock for the foreseeable future.***

We currently intend to retain all available funds and any future earnings to fund the development and growth of our business. As a result, we do not anticipate declaring or paying any cash dividends on shares of common stock in the foreseeable future. Any decision to declare and pay dividends in the future will be made at the discretion of our Board of Directors (the "***Board***") and will depend on, among other things, our business prospects, results of operations, financial condition, cash requirements and availability, certain restrictions related to our indebtedness, industry trends and other factors that the Board may deem relevant. Any such decision will also be subject to compliance with contractual restrictions and covenants in the agreements governing our current and future indebtedness. In addition, we may incur additional indebtedness, the terms of which may further restrict or prevent us from paying dividends on common stock. As a result, you may have to sell some or all of your shares of common stock after price appreciation in order to generate cash flow from your investment, which you may not be able to do. Our inability or decision not to pay dividends, particularly when others in our industry have elected to do so, could also adversely affect the market price of shares of common stock.

***If securities analysts do not publish research or reports about us, or if they issue unfavorable commentary about us or our industry or downgrade our common stock, the price of shares of common stock could decline.***

The trading market for shares of common stock will depend in part on the research and reports that third-party securities analysts publish about us and the industries in which we operate. We may be unable or slow to attract research coverage and if one or more analysts cease coverage of us, the price and trading volume of our securities would likely be negatively impacted. If any of the analysts that may cover us change their recommendation regarding our securities adversely, or provide more favorable relative recommendations about our competitors, the price of our securities would likely decline. If any analyst that may cover us ceases covering us or fails to regularly publish reports on us, we could lose visibility in the financial markets, which could cause the price or trading volume of our securities to decline. Moreover, if one or more of the analysts who cover us downgrades the common stock, or if our reporting results do not meet their expectations, the market price of shares of common stock could decline.

***Our issuance of additional shares of common stock or securities convertible or exchangeable into common stock could make it difficult for another company to acquire us, may dilute your ownership of us and could adversely affect our stock price.***

From time to time in the future, we may also issue additional shares of common stock or securities convertible into common stock pursuant to a variety of transactions, including acquisitions. The issuance by us of additional shares of common stock or securities convertible into common stock would dilute your ownership of us and the sale of a significant amount of such shares in the public market could adversely affect prevailing market prices of shares of common stock. In the future, we expect to obtain financing or to further increase our capital resources by issuing additional shares of our capital stock or offering debt or other equity securities, including senior or subordinated notes, debt securities convertible into equity, or shares of preferred stock. Issuing additional shares of our capital stock, other equity securities, or securities convertible into equity may dilute the economic and voting rights of our existing stockholders, reduce the market price of shares of common stock, or both. Debt securities convertible into equity could be subject to adjustments in the conversion ratio pursuant to which certain events may increase the number of equity securities issuable upon conversion. Preferred stock, if issued, could have a preference with respect to liquidating distributions or a preference with respect to dividend payments that could limit our ability to pay dividends to the holders of our common stock. Our decision to issue securities in any future offering will depend on market conditions and other factors beyond our control, which may adversely affect the amount, timing or nature of our future offerings. As a result, holders of common stock bear the risk that our future offerings may reduce the market price of shares of common stock and dilute their percentage ownership.

***Future sales, or the perception of future sales, of common stock by us or our existing stockholders in the public market could cause the market price for our common stock to decline.***

The sale of substantial amounts of shares of common stock in the public market, or the perception that such sales could occur, could harm the prevailing market price of shares of our common stock. These sales, or the possibility that these sales may occur, also might make it more difficult for us to sell equity securities in the future at a time and at a price that we deem appropriate.

All shares issued as merger consideration in the Business Combination are freely tradable without registration under the Securities Act of 1933, as amended (the "***Securities Act***") and without restriction by persons other than our "affiliates" (as defined under Rule 144), including our directors, executive officers and other affiliates, and certain other former QT Imaging stockholders.

The Company has registered in a resale registration statement on Form S-1 declared effective by the SEC on May 22, 2024, securities held by certain stockholders of the Company which have the right, subject to certain conditions, to require us to register the sale of their shares of common stock under the Securities Act, pursuant to the terms of a registration statement that we entered into with GigAcquisitions5 and certain other security holders of GigCapital5 and QT Imaging (the "***GigCapital5 Registration Rights Agreement***"). The Company has also registered in a resale registration statement on Form S-1 declared effective by the SEC on February 5, 2025, the securities sold in the private placement conducted in November 2024 as the purchasers received the right, subject to certain conditions, to require us to register the sale of their shares of common stock under the Securities Act, pursuant to the terms of a registration statement that we entered into ("***PIPE Registration Rights Agreement***"). We have also registered in a resale registration statement on Form S-1 declared effective by the SEC on December 31, 2025 additional securities of the Company, including those issued in further private placements conducted during 2025, as well as warrants that we have issued during 2025. The sale of a large number of shares by these stockholders, or the sale of shares by warrant holders following the exercise of these warrants, could cause the prevailing market price of shares of our common stock to decline. Significant sales of shares of our common stock may have negative pressure on the public trading price of our common stock.

The shares already registered for resale currently represent over 50% of the total number of shares outstanding, based on the number of shares of common stock outstanding as of March 24, 2026. Even though the current trading price is significantly below the Company's initial public offering price, based on the closing price of the common stock on March 24, 2026, certain of our stockholders may have an incentive to sell their shares because they will still profit on sales due to the lower prices at which they purchased their shares as compared to the public investors who acquired shares during the GigCapital5 initial public offering. For example, members of our founding stockholder, GigAcquisitions5, who received a distribution of shares from GigAcquisitions5 for which there is an effective resale registration statement, have a cost basis in up to 1,911,696 shares of common stock that were acquired at an effective purchase price of $0.0130776 per share, and, therefore, based on the closing price of the common stock, could earn an aggregate profit of approximately $12,534,842 million from the resale of such shares based upon the closing stock price on March 24, 2025.

To the extent that the selling securityholders under any of our registration statements on Form S-1 sell their shares or are perceived by the market as intending to sell them, the market price of shares of common stock could drop significantly. These factors could also make it more difficult for us to raise additional funds through future offerings of shares of common stock or other securities.

On October 3, 2025, we issued the pre-funded warrants (the "***Pre-Funded Warrants***"), which are exercisable for 1,808,055 shares at an exercise price of $0.0003 per share. In addition, the Company has other warrants that in the aggregate are exercisable for 34,306,749 shares of common stock at various exercise prices ranging from $1.20 per share to $6.90 per share. This includes the warrant that we issued to Lynrock Lake in connection with our loan agreement with Lynrock Lake (the "***Lynrock Lake Warrant***"), which is exercisable for 20,333,623 shares of common stock at an exercise price of $1.20 per share, but may be exercised on a "cashless basis."

In addition, the shares of common stock that will be issued upon exercise of stock options already granted pursuant to the terms of, or those shares of common stock reserved for future issuance under the 2024 Equity Incentive Plan will become eligible for sale in the public market once those shares are issued, subject to provisions relating to various vesting agreements and, in some cases, limitations on volume and manner of sale applicable to affiliates under Rule 144, as applicable. We have filed a registration statement on Form S-8 under the Securities Act to register shares of common stock or securities convertible into or exchangeable for shares of common stock issued pursuant to our equity incentive plans and may in the future file additional registration statements on Form S-8. Any such Form S-8 registration statements will automatically become effective upon filing. Accordingly, shares registered under such registration statements will be available for sale in the open market.

***As a public reporting company, we are subject to rules and regulations established from time to time by the SEC regarding our internal control over financial reporting.***

The Company is a public reporting company subject to the rules and regulations established from time to time by the SEC. These rules and regulations will require, among other things that the Company establish and periodically evaluate procedures with respect to its internal control over financial reporting. Reporting obligations as a public company are likely

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

to place a considerable strain on the Company's financial and management systems, processes and controls, as well as on its personnel.

In addition, as a public company, the Company will be required to document and test its internal control over financial reporting pursuant to Section 404 of the Sarbanes-Oxley Act so that its management can certify as to the effectiveness of the internal control over financial reporting. If the Company's not able to implement the requirements of Section 404, including any additional requirements once the Company's no longer an emerging growth company, in a timely manner or with adequate compliance, it may not be able to assess whether its internal control over financial reporting are effective, which may subject the Company to adverse regulatory consequences and could harm investor confidence and the market price of our common stock.

Additionally, once we are no longer an emerging growth company, we will be required to comply with the independent registered public accounting firm attestation requirement on our internal control over financial reporting. We will be an "emerging growth company" until the earlier of (1) the last day of the fiscal year (a) following September 28, 2026, the fifth anniversary of our initial public offering ("***IPO***"), (b) in which we have total annual gross revenue of at least $1.235 billion or (c) in which we are deemed to be a large accelerated filer, which means the market value of our common stock that is held by non-affiliates exceeds $700 million as of the last business day of our prior second fiscal quarter, and (2) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period. Until we cease being an emerging growth company stockholders will not have the benefit of an independent assessment of the effectiveness of our internal control environment.

***As an "emerging growth company," we cannot be certain if the reduced disclosure requirements applicable to "emerging growth companies" will make our common stock less attractive to investors.***

As an "emerging growth company," we may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not "emerging growth companies," including not being required to obtain an assessment of the effectiveness of our internal controls over financial reporting from our independent registered public accounting firm pursuant to Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and stockholder approval of any golden parachute payments not previously approved.

In addition, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended (the "***Exchange Act***")) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such an election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company's financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accountant standards used.

We cannot predict if investors will find our common stock less attractive because we will rely on these exemptions. If some investors find our common stock less attractive as a result, there may be a less active market for our common stock, our share price may be more volatile and the price at which our securities trade could be less than if we did not use these exemptions.

***Anti-takeover provisions in our governing documents and under Delaware law could make an acquisition of us more difficult, limit attempts by our stockholders to replace or remove our current management and limit the market price of our common stock.***

The Second Amended and Restated Certificate of Incorporation of the Company (the "***Charter***"), the Company's bylaws (the "***Bylaws***") and Delaware law contain provisions that could have the effect of rendering more difficult, delaying, or

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

preventing an acquisition deemed undesirable by the Board. Among other things, the Charter and/or the Bylaws include the following provisions:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a staggered board, which means that the Board will be classified into three classes of directors with staggered three-year terms and directors will only be able to be removed from office for cause;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• limitations on convening special stockholder meetings, which could make it difficult for our stockholders to adopt desired governance changes;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• prohibition on stockholder action by written consent, which means that our stockholders will only be able to take action at a meeting of stockholders and will not be able to take action by written consent for any matter;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• a forum selection clause, which means certain litigation against us can only be brought in Delaware;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• advance notice procedures, which apply for stockholders to nominate candidates for election as directors or to bring matters before an annual meeting of stockholders.

These provisions, alone or together, could delay or prevent hostile takeovers and changes in control or changes in our management. As a Delaware corporation, we are also subject to provisions of Delaware law, including Section 203 of the Delaware General Corporation Law ("***DGCL***"), which prevents interested stockholders, such as certain stockholders holding more than 15% of our outstanding common stock, from engaging in certain business combinations unless (i) prior to the time such stockholder became an interested stockholder, the board of directors approved the transaction that resulted in such stockholder becoming an interested stockholder, (ii) upon consummation of the transaction that resulted in such stockholder becoming an interested stockholder, the interested stockholder owned at least 85% of the common stock, or (iii) following board approval, such business combination receives the approval of the holders of at least two-thirds of our outstanding common stock not held by such interested stockholder.

Any provision of the Charter, the Bylaws or Delaware law that has the effect of delaying, preventing or deterring a change in control could limit the opportunity for our stockholders to receive a premium for their shares of our common stock and could also affect the price that some investors are willing to pay for our common stock.

***The Charter provides that the Court of Chancery of the State of Delaware will be the sole and exclusive forum for substantially all disputes between us and our stockholders, which could limit our stockholders' ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.***

***If we do not file and maintain a current and effective prospectus relating to the common stock issuable upon exercise of the public and private warrants, holders will only be able to exercise such warrants on a "cashless basis" and we have a large number of other warrants which are exercisable on a "cashless basis."***

If we do not file and maintain a current and effective prospectus relating to the common stock issuable upon exercise of the public and private warrants at the time that holders wish to exercise such warrants, they will only be able to exercise them on a "cashless basis" provided that an exemption from registration is available. As a result, the number of shares of common stock that holders will receive upon exercise of the public and private warrants will be fewer than it would have been had such holder exercised its warrant for cash. Further, if an exemption from registration is not available, holders would not be able to exercise on a cashless basis and would only be able to exercise their warrants for cash if a current and effective prospectus relating to the common stock issuable upon exercise of the warrants is available. Under the terms of the Warrant Agreement, dated as of September 23, 2021, between GigCapital5 and the Transfer Agent (the "***Warrant Agreement***"), we have agreed to use our best efforts to meet these conditions and to file and maintain a current and effective prospectus relating to the common stock issuable upon exercise of the warrants until the expiration of the warrants. However, we cannot assure you that we will be able to do so. If we are unable to do so, the potential "upside" of the holder's investment in us may be reduced or the warrants may expire worthless.

In addition, the outstanding Lynrock Lake Warrant, which is exercisable for 20,333,623 shares of common stock, is exercisable on a "cashless basis."

***There is no guarantee that the public and private warrants will ever be in the money, and they may expire worthless and the terms of warrants may be amended.***

The exercise price for the public and private warrants is $6.90 per share of common stock. There is no guarantee that the public and private warrants will ever be in the money prior to their expiration, and as such, the warrants may expire worthless.

In addition, the Company's public and private warrants were issued in registered form under the Warrant Agreement between Continental Stock Transfer & Trust Company, as warrant agent, and the Company. The Warrant Agreement provides that the terms of the warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least 50% of the then outstanding public warrants to make any other change. Accordingly, the Company may amend the terms of the warrants in a manner adverse to a holder if holders of at least 50% of the then outstanding public warrants approve of such amendment. Although the Company's ability to amend the terms of the warrants with the consent of at least 50% of the then outstanding public warrants is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the warrants, shorten the exercise period or decrease the number of shares and their respective affiliates and associates have of common stock purchasable upon exercise of a warrant.

***Our warrants will become exercisable for the common stock, which would increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders.***

Our private warrants and our public warrants issued as part of GigCapital5's IPO are exercisable for one share of common stock at $6.90 per share. In addition, we have issued warrants in various private placements and in connection with the issuance of debt. In November 2024, we issued warrants in a private placement (the "***November 2024 PIPE Warrants***") that have an exercise price of $2.016 per share. The Lynrock Lake Warrant has an exercise price of $1.20 per share. The warrants with a term of ten years from the initial exercise date for the purchase of 523,286 shares of common stock that we issued on April 9, 2025 (the "***Ten Year Common Warrants***") have an exercise price of $2.16 per share. The warrant with a term of five years from the initial exercise date to purchase up to an additional 68,447 shares of common stock that we issued on May 12, 2025 (the "***Recanati Warrant***") has an exercise price of $3.36 per share, the warrants for the purchase of 2,232,243 shares of common stock that we issued on October 3, 2025 pursuant to the terms and conditions of the Securities Purchase Agreement, dated September 30, 2025, (the "***Subscription Warrants***") have an exercise price of $4.50 per share, the Pre-Funded Warrants have an exercise price of $0.0003 per share, and the warrants with term of ten years from the initial exercise date for the purchase of 48,214 shares of common stock (the "***January 2026 Warrant***" and together with the warrants subject to the Warrant Agreement (the "***Warrant Agreement Warrants***"), the Lynrock Lake Warrant, the November 2024 PIPE Warrants, the Ten Year Common Warrants, the Recanati Warrant, the Pre-Funded Warrants and the Subscription Warrants, the "***Warrants***") have an exercise price of $6.43 per share. The additional shares of common stock issued upon exercise of the Warrants will result in dilution to the then existing holders of the common stock and increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market could adversely affect the market price of the common stock.

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

***We have no obligation to net cash settle the warrants other than the Lynrock Lake Warrant***

In no event will we have any obligation to net cash settle the warrants other than the warrants issued to Lynrock Lake. Furthermore, there are no contractual penalties for failure to deliver securities to the holders of the public and private warrants upon exercise of those warrants. Accordingly, those warrants may expire worthless.

***Our warrants will become, exercisable for common stock, which would increase the number of shares eligible for future resale in the public market and result in dilution to our stockholders.***

The Warrant Agreement Warrants, consisting of outstanding public warrants to purchase an aggregate of 7,882,807 shares of common stock are exercisable in accordance with the terms of the Warrant Agreement entered into in September 2021 governing those securities, as well as our private warrants and working capital warrants to purchase an aggregate of up to 296,445 shares of common stock, at an exercise price of $6.90 per share. Collectively, the Warrants are exercisable for a total of 34,306,749 shares of common stock, and in addition to the Warrant Agreement Warrants with an exercise price of $6.90, the other Warrants have exercise prices ranging from $0.0003 per share for the Pre-Funded Warrants to $6.43 per share for the January 2026 Warrant. To the extent such warrants are exercised, additional shares of common stock will be issued, which will result in dilution to the holders of common stock and increase the number of shares eligible for resale in the public market. Sales of substantial numbers of such shares in the public market or the fact that such warrants may be exercised could adversely affect the market price of common stock. However, there is no guarantee that the warrants will ever be in-the-money prior to their expiration. As such, the warrants may expire worthless.

***Certain of the Company's warrants are accounted for as a warrant liability and were recorded at fair value upon issuance with changes in fair value each period reported in earnings, which may have an adverse effect on the market price of the common stock.***

As of December 31, 2025, an aggregate of 889,364 private warrants and working capital warrants that are Warrant Agreement Warrants, which following the 3:1 reverse stock split that occurred on October 23, 2025 (the "***Reverse Stock Split***") were exercisable for 296,445 shares of common stock, were outstanding. These warrants became exercisable 30 days after completion of the Business Combination and are exercisable now that we have an effective registration statement under the Securities Act covering the shares of common stock of the Company issuable upon exercise for so long as a current prospectus relating to them is available and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder (or the Company permits holders to exercise their warrants on a cashless basis under certain circumstances). Furthermore, the Company may redeem outstanding warrants in certain circumstances; provided, however, that these warrants will not be redeemable by the Company so long as they are held by the initial purchasers or any of its permitted transferees, to which the initial purchaser transferred the private warrants in June 2024. Under GAAP, the Company is required to evaluate contingent exercise provisions of these warrants and then their settlement provisions to determine whether they should be accounted for as a warrant liability or as equity. Any settlement amount not equal to the difference between the fair value of a fixed number of the Company's equity shares and a fixed monetary amount precludes these warrants from being considered indexed to its own stock, and therefore, from being accounted for as equity. As a result of the provision that these warrants, when held by someone other than the initial purchasers or their permitted transferees, will be redeemable by the Company, the requirements for accounting for these warrants as equity are not satisfied. Therefore, the Company is required to account for these warrants as a warrant liability and record (a) that liability at fair value, and (b) any subsequent changes in fair value as of the end of each period for which earnings are reported. The impact of changes in fair value on earnings may have an adverse effect on the market price of our common stock.

**Other General Risks Applicable to the Company** 

***Under applicable employment laws, we may not be able to enforce covenants not to compete and therefore may be unable to prevent our competitors from benefiting from the expertise of some of our former employees.***

Our employment agreements generally include covenants not to compete. These agreements prohibit our employees, if they cease working for us, from competing directly with us or working for our competitors for a limited period. We may be unable to enforce these agreements under the laws of the jurisdictions in which our employees work at all or for a sufficient duration of time to prevent members of our management team from competing with us.

***We may not be able to attract and retain the highly skilled employees we need to support our planned growth.***

To continue to execute our business and our growth plan, we must attract and retain highly qualified personnel. Competition for these personnel is intense. We may not be successful in attracting and retaining qualified personnel. If we

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

fail to attract new personnel or fail to retain and motivate our current personnel, our business, financial condition, results of operations and future growth prospects could be severely harmed.

***Industry data, projections and estimates relied upon by us are inherently uncertain, subject to interpretation and may not have been independently verified.***

Information concerning our industry and the markets in which we operate and intend to operate, including industry projections and estimates, is obtained from publicly available information released by independent industry and research organizations and other third-party sources. We have not independently verified any such third-party information. In addition, projections, assumptions and estimates of the future performance of the industry in which we operate are subject to uncertainty and risk due to a variety of factors. As a result, inaccuracies in third-party information, or in the projections, may adversely impact the assumptions that are relied upon for our internal business planning and in the analysis of investors.

***We will incur increased costs and demands upon management as a result of complying with the laws and regulations affecting public companies, which could adversely affect the Company's business, results of operations, and financial condition.***

As a public company, we will incur significant legal, accounting and other expenses that the company did not incur as a private company, including costs associated with public company reporting requirements. We will also incur costs associated with corporate governance requirements, including requirements under the Sarbanes-Oxley Act of 2002 (the "Sarbanes-Oxley Act"), as well as rules implemented by the SEC and the Nasdaq. These rules and regulations are expected to increase the company's legal and financial compliance costs and to make some activities more time consuming and costly, which may adversely affect investor confidence and could cause our business or stock price to suffer.

***Certain estimates of market opportunity included in this annual report may prove to be inaccurate.***

This annual report includes our internal estimates of the addressable market for our products. Market opportunity estimates, whether obtained from third-party sources or developed internally, are subject to significant uncertainty and are based on assumptions and estimates that may not prove to be accurate. The estimates in this annual report relating to the size of our target market, market demand and adoption, capacity to address this demand, and pricing may prove to be inaccurate. The addressable market we estimate may not materialize for many years, if ever, and even if the markets in which we compete meet the size estimates in this annual report, our business could fail to successfully address or compete in such markets.

***We may be required to take write-downs or write-offs, restructuring and impairment or other charges that could have a significant negative effect on our financial condition, results of operations and stock price, which could cause you to lose some or all of your investment.***

We may be forced to later write-down or write-off assets, restructure our operations, or incur impairment or other charges that could result in losses if material issues are discovered or factors that are outside of our control subsequently arise that require us to do so. Unexpected risks may arise and previously known risks may materialize in a manner not consistent with our existing risk analysis. Even though these charges may be non-cash items and may not have an immediate impact on our liquidity, the fact that we report charges of this nature could contribute to negative market perceptions about us or our securities. In addition, charges of this nature may cause us to be unable to obtain future financing on favorable terms or at all.

***Exchange rate fluctuations between the U.S. dollar and other currencies and inflation may negatively affect our results of operations, and we may not be able to hedge our currency exchange risks successfully.***

The U.S. dollar is our functional and reporting currency. Payments we receive from international distribution partners and others that purchase our products and services may be subject to currency fluctuations if the remitting party does not initiate payment in U.S. dollars. Given our general lack of currency hedging arrangements to protect us from fluctuations in the exchange rates of foreign currencies in relation to the U.S. dollar (and/or from inflation of such foreign currencies), we may be exposed to material adverse effects from such movements. Our exchange rate exposure may change over time as our business evolves and could result in increased costs or reduced revenue and could affect our actual cash flow. Changes in the relative values of currencies occur regularly and, in some instances, may have a significant impact on our operating results. The rate of inflation in countries in which we sell and service our products, or in currency exchange rates, may materially change and we might not be able to effectively mitigate these risks.

***We will incur significant increased expenses and administrative burdens as a public company, which could have an adverse effect on its business, financial condition and results of operations.***

We face increased legal, accounting, administrative and other costs and expenses as a public company than the Company did as a private company. The Sarbanes-Oxley Act, including the requirements of Section 404, as well as rules and regulations subsequently implemented by the SEC, the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and the rules and regulations promulgated and to be promulgated thereunder, Public Company Accounting Oversight Board (United States) (the "PCAOB") and the securities exchanges, impose additional reporting and other obligations on public companies. Compliance with public company requirements will increase costs and make certain activities more time-consuming. A number of those requirements require the Company to carry out activities QT Imaging has not done previously. For example, the Company created new board committees and adopted new internal controls and disclosure controls and procedures. In addition, expenses associated with SEC reporting requirements will be incurred. Furthermore, if any issues in complying with those requirements are identified (for example, if the auditors identify any additional material weaknesses or significant deficiencies in the internal control over financial reporting), the Company could incur additional costs rectifying those issues, and the existence of those issues could adversely affect the Company reputation or investor perceptions of it. It may also be more expensive to obtain director and officer liability insurance. Risks associated with the Company' status as a public company may make it more difficult to attract and retain qualified persons to serve on our Board or as executive officers. The additional reporting and other obligations imposed by these rules and regulations will increase legal and financial compliance costs and the costs of related legal, accounting and administrative activities. These increased costs will require the Company to divert a significant amount of money that could otherwise be used to expand the business and achieve strategic objectives. Advocacy efforts by stockholders and third parties may also prompt additional changes in governance and reporting requirements, which could further increase costs.

***Effective internal controls are necessary for us to provide reliable financial reports and prevent fraud.***

If we identify any additional material weaknesses in the future, any such identified material weakness could limit our ability to prevent or detect a misstatement of our accounts or disclosures that could result in a material misstatement of our annual or interim consolidated financial statements. In such case, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable stock exchange listing requirements, investors may lose confidence in our financial reporting and our stock price may decline as a result. We cannot assure you that the measures we have taken to date, or any measures we may take in the future, will be sufficient to avoid potential future material weaknesses.

***Unanticipated changes in effective tax rates or adverse outcomes resulting from examination of our income or other tax returns could adversely affect our financial condition and results of operations.***

We will be subject to income taxes in the United States and other jurisdictions, and our tax liabilities will be subject to the allocation of expenses in differing jurisdictions. Our future effective tax rates could be subject to volatility or adversely affected by a number of factors, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in the valuation of our deferred tax assets and liabilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• expected timing and amount of the release of any tax valuation allowances;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• tax effects of stock-based compensation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• costs related to intercompany restructurings;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• changes in tax laws, regulations or interpretations thereof; or

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• lower than anticipated future earnings in jurisdictions where we have lower statutory tax rates and higher than anticipated future earnings in jurisdictions where we have higher statutory tax rates.

In addition, we may be subject to audits of our income, sales and other transaction taxes by taxing authorities. Outcomes from these audits could have an adverse effect on our financial condition and results of operations.

***Our only significant asset is its ownership interest in QT Imaging, Inc. and such ownership may not be sufficient to pay dividends or make distributions or loans to enable the Company to pay any dividends on the common stock or satisfy its other financial obligations.***

We have no direct operations and no significant assets other than its ownership of QT Imaging, Inc. We depend on QT Imaging, Inc. for distributions, loans and other payments to generate the funds necessary to meet our financial obligations,

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

including our expenses as a publicly traded company and to pay any dividends with respect to our common stock. The financial condition and operating requirements of QT Imaging, Inc. may limit our ability to obtain cash from QT Imaging, Inc. The earnings from, or other available assets of, QT Imaging, Inc. may not be sufficient to pay dividends or make distributions or loans to enable us to pay any dividends on the common stock or satisfy its other financial obligations.

Our ability to make distributions, loans and other payments for the purposes described above and for any other purpose may be limited by credit agreements to which the Company is party from time to time, including the existing credit agreement with Lynrock Lake (the "***Lynrock Lake Credit Agreement***"), and will be subject to the negative covenants set forth therein. Any loans or other extensions of credit to QT Imaging, Inc. from the Company will be permitted only to the extent there is an applicable exception to the investment covenants under this loan agreement. Similarly, any dividends, distributions or similar payments to QT Imaging, Inc. from the Company will be permitted only to the extent there is an applicable exception to the dividends and distributions covenants under this loan agreement.

**Item 1B: Unresolved Staff Comments**

**Item 1C: Cybersecurity**

The operation of our business depends on our information technology systems. We rely on our information technology systems to effectively manage sales and marketing data, accounting and financial functions, inventory management, product development tasks, clinical data, customer service and technical support functions. Our information infrastructure and products are vulnerable to cyber-based attacks. We have not incurred such an attack.

Cyber-based attacks can include computer viruses, denial-of-service attacks, phishing attacks, ransomware attacks and other introduction of malware to computers and networks; unauthorized access through the use of compromised credentials; exploitation of design flaws, bugs or security vulnerabilities; intentional or unintentional acts by employees or other insiders with access privileges; and intentional acts of vandalism by third parties and sabotage.

We have developed and implemented a risk-based program focused on assessing and identifying cybersecurity risks, and managing these risks by taking cybersecurity measures to protect the confidentiality, integrity, and availability of our critical systems and information.

Our cybersecurity risk management is integrated into our overall risk management framework, and shares common methodologies, reporting channels and governance processes that apply across the risk management program to other legal, compliance, strategic, operational, and financial risk areas. We have engaged an information security consultant to assist in our cybersecurity risk management program.

Our Board of Directors is primarily responsible for overseeing and governing our cybersecurity risk management program. The Audit Committee of our Board of Directors is responsible for overseeing management's processes for identifying and mitigating risks that affect our operations, including cybersecurity risks. Senior leadership regularly briefs the full Board of Directors on our cybersecurity and information security posture and the Audit Committee is to be apprised of cybersecurity incidents deemed to pose a critical risk to our information technology ("***IT***") assets or business. We rely upon in-house and third-party cybersecurity vendors to monitor our IT systems and assets and have a governance structure and processes as described above to assess, identify, manage, and report cybersecurity risks.

We continue to assess the risks and changes in the cyber environment and invest in enhancements to our cybersecurity capabilities.

Although we have not, as of the date of this annual report, experienced a cybersecurity incident that materially affected our business, financial condition and results of operations, we can provide no assurance that we will not experience a material cybersecurity incident in the future.

**Overview** 

We are a medical device company founded in 2012 and engaged in the research, development, and commercialization of innovative body imaging systems using low energy sound. We believe that medical imaging is critical to the detection, diagnosis, and treatment of disease and that it should be safe, affordable, and accessible. Our goal is to improve global health outcomes through the development and commercialization of imaging devices that address critical healthcare challenges with accuracy and precision.

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

With the support of nearly $18.0 million in financial support from the U.S. National Institutes of Health, we developed a novel, comprehensive body imaging technology that has high resolution, high sensitivity, high specificity, high positive and negative predictive values, and is safe and inexpensive. The technology is based on ultra-low frequency transmitted sound and uses a one-of-a-kind novel sound back-scatter design and inverse-scattering reconstruction to create its images.

Our current QT Breast Scanner is a Class II device subject to premarket notification and clearance under Section 510(k) of the FDCA. On August 23, 2016, we (formerly, QT Ultrasound LLC) submitted a Section 510(K) Summary of Safety and Effectiveness application for the QT Breast Scanner in accordance with 21 CFR 807.92 under 510(K) Number K162372. As part of meeting the general requirements for basic safety and essential performance of the QT Breast Scanner (formerly, QT Ultrasound Breast Scanner) pursuant to AAMI ES60601-1:2005/(R)2012 and A1:2012 Medical electrical equipment, testing was conducted by Intertek, an independent testing laboratory, located in Menlo Park, CA. Intertek also conducted applicable testing pursuant to IEC 60601-1-6 Edition 3.1 2013-10-Medical electrical equipment Part 1-6 General requirements for safety - Collateral Standard: Usability. In addition, we conducted, and Intertek witnessed, all applicable testing pertaining to the requirements for the safety of ultrasonic medical diagnostic and monitoring equipment and to demonstrate compliance with the "Acoustic Output Measurement Standard for Diagnostic Ultrasound Equipment". This test on acoustic output was pursuant to IEC 60601-2-37 Edition 2.0.2007 Medical electrical equipment - Part 2-37: Particular requirements for the basic safety and essential performance of ultrasonic medical diagnostic and monitoring equipment. Finally, system verification testing was conducted to ensure that the QT Breast Scanner met all design and other requirements including but not limited to that no new issues of safety or effectiveness compared to the predicate device, SoftVue System manufactured by Delphinus Medical Technologies, were raised.

Since our inception, we have devoted substantially all our financial resources to acquiring and developing the base technology for our body imaging systems, conducting research and development activities, securing related intellectual property rights, and for general corporate operations and growth. On June 6, 2017, the FDA, in response to QT Imaging's Section 510(K) Summary of Safety and Effectiveness premarket notification, determined that the QT Breast Scanner is substantially equivalent to the predicate device. Our use of the words "safe", "safety", "effectiveness", and "efficacy" in relation to the QT Breast Scanner in this Management's Discussion and Analysis and all other documents related to us is limited to the context of the Section 510(K) Summary of Safety and Effectiveness that was reviewed and responded to by the FDA.

Our strategies for commercializing the QT Breast Scanner include the following:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Create disruptive technological innovation (software, artificial intelligence, and smart physics) to improve medical imaging and thus health care quality and access.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Continue to improve our high quality, high resolution, native 3D, reproducible image quality regardless of operator or breast size/tissue type breast imaging technology, as well as the techniques for quantifiable analysis, comparison, and training.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Partner with strategic business and distribution channels to address the U.S. market for breast imaging immediately and, other regions in the future, to place the QT Breast Scanner in hospitals, radiology centers, etc. and generate awareness of the benefits of our technology.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Perform manufacturing internally to us and partner strategically for large scale manufacturing.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expand the market by supporting additional Direct-to-Customer and Direct-to-Patient approaches to enable the ability to lower health care costs and increase access via personal medical imaging.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Provide a new social and economic opportunity for consumers to take control of some aspects of their own health care—such as imaging for minor injuries or medical conditions without needing a healthcare "gate-keeper."

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Focus our intellectual capabilities and ethical framework to become unified in our mission to improve the quality and lower the cost of health care world-wide . . . "It's about time."

On June 18, 2024, we entered into the NXC Distribution Agreement with NXC Imaging, Inc. ("NXC") to appoint NXC as the exclusive reseller to market, advertise, and resell QT Breast Scanners in the U.S. and U.S. territories. NXC will purchase for the purpose of reselling, leasing or renting QT Breast Scanners directly to its customers, but is not obligated to purchase any particular quantity of QT Breast Scanners from us. We have reserved the right to sell directly to customers as an exception. Furthermore, we may, in our sole discretion, sell the QT Breast Scanners to any other person or entity

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

anywhere in the world without notice to NXC or NXC's prior consent. NXC is also allowed to assign sales agents for the purpose of QT Breast Scanner sales. NXC's purchases will be in accordance with an agreed upon product pricing schedule (subject to change upon 60 days' prior written notice by us), provided that neither NXC nor its assigned sales agents may mark-up the cost of the QT Breast Scanners more than twenty percent (20%) unless otherwise mutually agreed to between NXC and us. Each order will include information reasonably requested by us and is subject to our acceptance, after which it becomes an approved order. Any such approved orders are non-cancellable and not subject to rescheduling after acceptance by us. Any orders not accepted by us in writing are deemed rejected. On December 11, 2024, we and NXC entered into the Amended NXC Distribution Agreement, which amends and restates the NXC Distribution Agreement in its entirety, making some modifications to the NXC Distribution Agreement but retaining other terms. We further amended the Amended NXC Distribution Agreement on March 28, 2025. The Amended NXC Distribution Agreement has a term that runs until December 31, 2026, unless earlier terminated or extended by mutual written agreement. As of December 31, 2025, we have delivered 48 QT Breast Scanners to NXC and NXC's customers pursuant to the NXC Sales Agent Agreement and Amended NXC Distribution Agreement.

On March 28, 2025, we entered into the Canon Manufacturing Agreement (the "***Canon Manufacturing Agreement***") with Canon Medical Systems, Inc. ("***CMSC***"). Pursuant to the terms of the Canon Manufacturing Agreement, we appointed CMSC as the exclusive manufacturer of the QT Breast Scanners to be distributed by NXC. QTI retains the right to perform manufacturing in Novato, California. The purchase prices applicable to the purchase orders as of the date of the Canon Manufacturing Agreement shall be separately agreed between the parties in writing. The term of the Canon Manufacturing Agreement is through December 31, 2026.

On August 21, 2025, we entered into the Gulf Medical Distribution Agreement with GMC, a corporation organized and existing under the laws of Saudi Arabia, for an Initial Term of three years . Under the terms of the Gulf Medical Distribution Agreement, we shall authorize and grant to GMC the exclusive right to market, advertise and sell the QT Breast Scanners and the QTI Cloud SaaS platform subscriptions in the GMC Territory. If GMC has met the GMC Minimum Purchase Requirements during the Initial Term, the Gulf Medical Distribution Agreement shall automatically be extended for an additional one-year term. GMC agrees to meet or exceed the GMC Minimum Purchase Requirements during the Initial Term. In the event GMC fails to meet these GMC Minimum Purchase Requirements in any year during the Initial Term, we may, at its sole option, (a) terminate GMC's exclusive distributorship rights for the sale and promotion of the Approved Products granted under this Agreement and appoint other distributors for the GMC Approved Products in the GMC Territory, or (b) terminate the Gulf Medical Distribution Agreement. Should we elect to so terminate GMC's exclusive distributorship in the Territory, we may continue to sell the GMC Approved Products to GMC for GMC to distribute on a non-exclusive basis in the Territory in accordance with the terms and conditions of the Gulf Medical Distribution Agreement, and GMC's ongoing obligations with regard to its GMC Minimum Purchase Requirements for the GMC Approved Products shall terminate. Should the Company be unable to furnish GMC with sufficient quantities of the GMC Approved Products, as may be requested by GMC in its Release Orders (as defined below) submitted to us in accordance with the terms of the Gulf Medical Distribution Agreement, then GMC's Minimum Purchase Requirement shall be reduced by the quantity of GMC Approved Products that the Company is unable to deliver as requested. GMC shall secure all required governmental approvals, permits, licenses, customs clearances, and authorizations required for shipment to and use of the QT Breast Scanners in the Territory. We shall provide training and professional services to GMC during the term of the Gulf Medical Distribution Agreement and shall retain all intellectual property rights. Except as GMC and we may otherwise mutually agree in writing, provided that GMC maintains a credit limit with our credit insurance provider that has been approved in writing by us, GMC shall pay the Company fifty percent (50%) of the total price of the GMC Release Order upon order placement and fifty percent (50%) within 45 days from the date of shipping of the GMC Approved Products to GMC's designated location(s), or in any of the agreed upon payment terms. We have provided for a limited warranty of at least one year, and up to five years, depending on the purchase price paid by a client of GMC for a GMC Approved Product. The Gulf Medical Distribution Agreement can be terminated only with the approval of both parties and, upon termination, GMC shall be permitted to sell any QT Breast Scanners that it holds in accordance with the Gulf Medical Distribution Agreement.

On January 19, 2026, we entered into an exclusive distribution agreement for the Company's Breast Acoustic CT scanners and QTI Cloud SaaS Platform in the UAE with Al Naghi Medical Co., a leading distributor of medical devices. The agreement provides for MOQs of seven scanners in 2026 (starting in the second quarter), increasing to 16 scanners in 2027 and 20 scanners in 2028, for a total minimum of 43 scanners representing revenue of more than $24 million upon FDA approval in the UAE.

We have incurred net operating losses and negative cash flows from operations since our inception and had an accumulated deficit of $53.0 million as of December 31, 2025. During the year ended December 31, 2025, we incurred a net loss of $21.1 million and used $9.0 million of cash in operating activities. We continue to incur losses, and our ability to achieve

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

and sustain profitability will depend on the achievement of sufficient revenues to support our cost structure. We may never achieve profitability and, unless and until we do, we will need to continue to raise additional capital.

We expect to incur additional recurring administrative expenses associated as a publicly traded company, including costs associated with compliance under the Exchange Act, annual and quarterly reports to stockholders, transfer agent fees, audit fees, incremental director and officer liability insurance costs, Sarbanes-Oxley Act compliance readiness, and director and officer compensation.

**Recent Developments**

On February 26, 2025, we entered into the Lynrock Lake Credit Agreement that provides a senior secured term loan (the "***Lynrock Lake Term Loan***") with Lynrock Lake. The Lynrock Lake Credit Agreement is secured by a first priority lien on substantially all our assets and provides for a term loan in the aggregate principal amount of $10.1 million at an interest rate of 10.0% per annum, compounded quarterly. The maturity date of the Lynrock Lake Credit Agreement is March 31, 2027. Furthermore, in connection with the Lynrock Lake Term Loan, we issued the Lynrock Lake Warrant, which is a warrant to purchase 20,333,623 shares of our common stock at an exercise price of $1.20 per share. The Lynrock Lake Warrant is exercisable until February 26, 2035. Lynrock Lake may cashless exercise the Lynrock Lake Warrant. The Lynrock Lake Warrant is also subject to anti-dilution adjustments to the exercise price and the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant in the event that we issue shares of common stock (or derivative securities) at a price that is either less than the $1.20 exercise price or the fair market value of a share of common stock from the immediately prior trading day.

On February 26, 2025, we used a portion of the proceeds of the Lynrock Lake Term Loan to pay Yorkville an amount equal to $3.0 million in cash and issued to Yorkville a warrant to purchase 5,000,071 shares of its common stock at an exercise price of $1.20 per share pursuant to a Warrant to Purchase Common Stock (the "***Yorkville Warrant***") to fully settle and discharge our obligations under the Yorkville Note and extinguish the Yorkville Note as having been fully performed. The Yorkville Warrant is exercisable until February 26, 2030. Yorkville may cashless exercise the Yorkville Warrant. The Yorkville Warrant is also subject to adjustments in the event that our common stock undergoes a split, reverse-split or similar event. Furthermore, the Yorkville Warrant has provided the holder with piggyback registration rights. We and Yorkville also entered into that certain Termination Agreement, dated February 26, 2025 (the "***Termination Agreement***"), pursuant to which the parties acknowledged the termination of the SEPA effective February 26, 2025.

On February 26, 2025, we used a portion of the proceeds of the Lynrock Lake Term Loan to pay Cable Car an amount equal to the full principal, interest and fees amount of approximately $1.6 million in cash to fully settle and discharge our obligations under the Cable Car Note and extinguish the Cable Car Note as having been fully performed.

In connection with the issuance of the Lynrock Lake Term Loan, on February 26, 2025, the maturity dates on both the Convertible Note Payable and Working Capital Notes were extended to October 21, 2027.

On April 9, 2025, we entered into a Securities Purchase Agreement (the "First Securities Purchase Agreement") by and between the Company, on the one hand, and Dr. Avi Katz, the Chairman of the board of directors, and Dr. Raluca Dinu, the Chief Executive Officer and a member of the board of directors, on the other hand, for the "***April 2025 Private Placement***"). On April 24, 2025, at the closing of the April 2025 Private Placement, we issued (i) 261,644 shares of common stock at a per share purchase price of $1.911, which represented 110% of the volume weighted trading price for the common stock on April 9, 2025; and (ii) the Ten Year Common Warrants with a term of ten years from the initial exercise date to purchase up to an additional 523,286 shares of common stock with a per share exercise price of $2.16. The aggregate gross proceeds to us from the April 2025 Private Placement was approximately $0.5 million, before deducting the offering expenses payable by us, which expenses consisted solely of legal fees.

On May 12, 2025, we entered into a Securities Purchase Agreement (the "***Second Securities Purchase Agreement***") for the Second Private Placement in an amount of approximately $0.2 million, pursuant to which we issued 68,447 shares of common stock plus the Recanati Warrant to purchase 68,447 shares of common stock. The Second Private Placement provides a per share purchase price of $2.922, which represents 110% of the five-day volume weighted trading price for the common stock through May 9, 2025, and the per share exercise price of the Recanati Warrant is $3.36.

On August 19, 2025 our stockholders approved the Certificate of Amendment to effect a reverse stock split of the outstanding shares of our common stock, par value $0.0001 per share, at a specific ratio within a range of 2:1 to 20:1, with the specific ratio to be fixed within this range by our board of directors in its sole discretion without further stockholder approval. Our board of directors fixed the Reverse Stock Split ratio at 3:1, such that each three shares of common stock

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

were combined and reconstituted into one share of common stock effective October 23, 2025. In connection with the Reverse Stock Split, the CUSIP number of the common stock has changed to 746962307. The common stock began trading on the OTCQB Venture Market on a reverse split-adjusted basis on October 24, 2025. Except as noted, all share, stock option, warrant, and per share information throughout these consolidated financial statements have been retroactively adjusted to reflect this Reverse Stock Split.

On August 26, 2025, the Company and Lynrock Lake entered into the First Amendment to the Lynrock Lake Credit Agreement (the "***Lynrock Lake Amended Credit Agreement***") to add an additional tranche of $5.0 million ("***Tranche B***") and increase the aggregate principal amount of the Lynrock Lake Term Loan to $15.1 million. The proceeds of Tranche B were used to repurchase the Yorkville Warrant and was subsequently repaid in full, along with repayment premium and accrued interest, on October 6, 2025.

On September 30, 2025, we entered into a Securities Purchase Agreement, (the "***Third Securities Purchase Agreement***"), by and between us, on the one hand, and certain accredited investors and qualified institutional buyers, led by Sio Capital Management, LLC, on the other hand, (together, the "***Purchasers***") for a private placement (the "***October 2025 Private Placement***") of securities. At the closing of the October 2025 Private Placement on October 3, 2025, we issued (i) 2,232,243 shares of our common stock, par value $0.0001 per share; (ii) the Subscription Warrants with a term of five years from the initial exercise date to purchase up to an additional 4,040,272 shares of common stock; and (iii) the Pre-Funded Warrants to purchase up to an additional 1,808,055 shares of common stock, exercisable any time after its issuance. The purchase price of each share of common stock is $4.50 (the "***Per Share Purchase Price***") and the purchase price for each Pre-Funded Warrant is $4.4997 (the "***Per Pre-Funded Warrant Purchase Price***"). Both of these amounts were paid by the Purchasers at the closing of the October 2025 Private Placement. The aggregate gross proceeds to us from the October 2025 Private Placement was approximately $18.2 million, before deducting the offering expenses payable by us, which expenses consist solely of legal fees and the amounts provided for pursuant to a placement agency agreement In addition, the per share exercise price of each Subscription Warrant is $4.50 and the per share exercise price of each Pre-Funded Warrant is $0.0003.

On January 22, 2026, the Company and the Chairman of its Board of Directors, entered in a Securities Purchase Agreement for a private placement of securities (the "***January 2026 Private Placement***"). At the closing of the 2026 Private Placement, the Company issued 24,107 shares of the Company's common stock (the "***January 2026 Shares***"), par value $0.0001 per share, and the January 2026 Warrant with a term of ten years from the initial exercise date to purchase up to an additional 48,214 shares of common stock. The January 2026 Warrant will be exercisable beginning six months after its issuance at the closing of the January 2026 Private Placement. The purchase price of the January 2026 Shares is $6.43, which represents 110% of the 5-day volume weighted trading price for the common stock on January 22, 2026, and the per share exercise price of the January 2026 Warrant is $6.43. The aggregate gross proceeds to the Company from the January 2026 Private Placement was approximately $0.2 million. The Company intends to use the net proceeds from the offering for working capital purposes.

Effective January 28, 2026, upon meeting all of the Nasdaq listing requirements, the Company's common stock was uplisted from the OTCQB Venture Market to the Nasdaq Capital Market and began trading under the ticker symbol "QTI."

**Components of Our Results of Operations** 

***Revenue***

Revenue consists of revenue from the sale of our products including the QT Breast Scanner, associated software, accessories, and related services, which are primarily training and maintenance. For sales of products (which include the QT Breast Scanner and any accessories), revenue is recognized when a customer obtains control of the promised goods. The amount of revenue recognized reflects the consideration we expect to be entitled to receive in exchange for these goods. Service revenue is generally related to maintenance and training the customer. Service revenue is recognized at the time the related performance obligation is satisfied, in an amount that reflects the consideration that we expect to receive in exchange for those services.

***Cost of Revenue***

Cost of revenue consists of our product costs, including manufacturing costs, personnel costs and benefits, duties and other applicable importing costs, shipping and handling costs, packaging, warranty replacement costs, fulfillment costs and inventory obsolescence and write-offs. We expect our cost of revenue to increase in absolute dollars and decrease as a percentage of revenues over time as we shift to new manufacturing processes and vendors that we anticipate will result in greater efficiency and lower per unit costs.

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

We expect we will continue to invest additional resources into our products to expand and further develop our offerings. The level and timing of investment in these areas could affect our cost of revenue in the future.

***Operating Expenses***

*Research and Development Expenses* 

Research and development expenses consist primarily of costs incurred in connection with the research and development of our products, which include payroll and payroll related expenses, facilities costs, depreciation expense, materials and supplies, and consultant costs.

We expense all research and development costs in the periods in which such costs are incurred. Research and development activities are central to our business. We expect that our research and development expenses will increase substantially for the foreseeable future as we continue to invest in the development of the QT Breast Scanner.

We cannot reasonably determine the nature, timing and costs of the efforts that will be necessary to build our QTI Cloud SaaS platform, run clinical trials that are necessary to generate biomarker data, and reduce the bill of materials and other costs to manufacture the QT Breast Scanner. Our research and development expenses may vary significantly based on factors such as, without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The timing and progress of development activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to maintain our current research and development programs and to establish new ones;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The receipt of regulatory approvals from applicable regulatory authorities without the need for independent clinical trials or validation;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Duration of subject participation in any trials and follow-ups;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The countries and jurisdictions in which the trials are conducted;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Length of time required to enroll eligible subjects and initiate trials;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Per trial subject costs;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Number of trials required for regulatory approval;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The timing, receipt, and terms of any marketing approvals from applicable regulatory authorities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The success of our distribution arrangements, and our ability to establish new licensing or collaboration arrangements outside of U.S.;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The hiring and retention of research and development personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Obtaining, maintaining, defending, and enforcing intellectual property rights; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The phases of development of our product candidates.

Any changes in the outcome of any of these variables with respect to the development of our products or product candidates could significantly change the costs and timing associated with the development of these products and product candidates.

*Selling, General and Administrative Expenses* 

Selling, general and administrative expenses consist primarily of personnel costs, costs related to maintenance and filings of intellectual property, and other expenses for outside professional services, including legal, consulting, investor relations, audit and accounting services. Our personnel costs consist of salaries, benefits and stock-based compensation expenses. Selling, general and administrative expenses include facilities, depreciation and other expenses, which include direct or

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

allocated expenses for rent and maintenance of facilities and insurance. Selling, general and administrative expenses also include consulting expenses and costs for conferences, meetings, and other events.

We anticipate that our selling, general and administrative expenses will increase to support our expanding headcount and operations, increased costs of operating as a public company, the development of a commercial infrastructure to support commercialization of our products and product candidates, increased support for existing and new distribution partner relationships, and the use of outside service providers such as insurers, consultants, lawyers, and accountants. We also expect selling expenses to increase in the near term as we promote our brand through marketing and advertising initiatives, expand market presence and hire additional personnel to drive penetration and generate leads.

***Revenue***

Revenue increased by $14.0 million to $18.9 million for the year ended December 31, 2025 from $4.9 million for the year ended December 31, 2024. The increase in revenue was primarily due to the sale of 40 QT Breast Scanners for year ended December 31, 2025 as compared with twelve scanners sold for the year ended December 31, 2024 due to the MOQs in accordance with the Amended NXC Distribution Agreement.

Cost of revenue increased by $8.1 million to $10.3 million for the year ended December 31, 2025 from $2.2 million for the year ended December 31, 2024. The increase was primarily due to the sale of 40 QT Breast Scanners for the year ended December 31, 2025 as compared with twelve scanners sold for the year ended December 31, 2024. Gross margin decreased to 45% for the year ended December 31, 2025, as compared to 54% for the year ended December 31, 2024, due to the sale of 18 Model B scanners with a higher cost in 2025, the sale of 3 scanners manufactured by Canon at a higher cost in 2025, and a $1.7 million increase in the allocation of overhead from selling, general and administrative expenses to cost of revenue.

***Operating Expenses***

*Research and Development Expenses*

Research and development expenses increased by $0.7 million to $3.9 million for the year ended December 31, 2025 from $3.3 million for the year ended December 31, 2024. The increase was primarily due to an increase in professional service expenses of $0.5 million and an increase in employee compensation expenses of $0.3 million.

*Selling, General and Administrative Expenses*

Selling, general and administrative expenses decreased by $2.5 million to $9.1 million for the year ended December 31, 2025 from $11.6 million for the year ended December 31, 2024. The decrease was mainly attributable to a $4.3 million decrease in transaction expenses related to the Business Combination in 2024, an increase in the allocation of overhead of $1.7 million from selling, general and administrative expenses to cost of revenue, and a $0.3 million decrease in insurance expenses, partially offset by an increase in employee compensation expenses of $2.7 million, an increase in professional services expenses of $0.5 million, and an increase in technology infrastructure expenses of $0.2 million.

*Other expense, net*

Other expense, net increased by $8.2 million to $8.8 million for the year ended December 31, 2025 from an expense of $0.6 million for the year ended December 31, 2024. The increase was primarily due to $6.6 million in noncash expense incurred at issuance of the Lynrock Lake Term Loan, and $2.2 million in expense due to an extinguishment loss and modification charges for the Yorkville Note and Cable Car Note during the year ended December 31, 2025, which was partially offset by the modification expense of $0.2 million related to the decrease in exercise price of our private placement warrants and working capital note warrants in the year ended December 31, 2024.

*Change in fair value of warrant liability*

Change in fair value of warrant liability changed by $3.8 million to an expense of $3.6 million for the year ended December 31, 2025 from an income of $0.2 million for the year ended December 31, 2024. The change was primarily due to increases in the market value of the Lynrock Lake Warrant and Yorkville Warrant, which were issued in the first quarter of 2025 and subsequently revalued on June 11, 2025 upon modification.

*Change in fair value of derivative liability*

Change in the fair value of derivative liability changed by $4.7 million to income of $0.1 million for the year ended December 31, 2025 from income of $4.8 million for the year ended December 31, 2024. The change was primarily due to the decline in the value of our common stock. The derivative liability was extinguished during the first quarter of 2025 as a result of the extinguishment of the loan with Yorkville.

*Change in fair value of earnout liability*

Change in the fair value of earnout liability changed by $5.0 million to an expense of $1.8 million for the year ended December 31, 2025 from income of $3.2 million for the year ended December 31, 2024. The change was primarily due to changes to the probability of outcome related to our revenue assumptions.

*Interest expense, net*

Interest expense, net decreased by $1.9 million to $2.6 million for the year ended December 31, 2025 from $4.5 million for the year ended December 31, 2024. The decrease is primarily due to the extinguishment of the Yorkville Note and the Cable Car loan in February 2025, resulting in decreases in interest expense and amortization of the debt discount of $3.2 million for the Yorkville Note and $0.3 million for the Cable Car Note in the 2025 period, and a decrease in interest expense of $0.2 million from the private secured convertible bridge financing extinguished in 2024, partially offset by an increase in interest expense and amortization of the debt discount of $1.9 million for the Lynrock Lake Term Loan.

**Liquidity and Capital Resources**

***Sources of Liquidity***

Liquidity describes our ability to meet financial obligations which arise during the normal course of business. To date, we have financed our operations primarily through the sale of equity securities, issuances of convertible notes and other debt,

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

and grants from the U.S. government. We expect to derive future liquidity primarily through our revenues with customers and sale of equity securities. Our current liquidity position consists of cash on hand and certificates of deposit.

We have incurred net operating losses and negative cash flows from operations since our inception and had an accumulated deficit of $53.0 million as of December 31, 2025. During the year ended December 31, 2025, we incurred a net loss of $21.1 million and used $9.0 million of cash in operating activities. We expect to continue to incur losses, and our ability to achieve and sustain profitability will depend on the achievement of sufficient revenues to support our cost structure. We may never achieve profitability and, unless and until we do, we will need to continue to raise additional capital.

On February 26, 2025, we entered into the Lynrock Lake Credit Agreement that provides the Lynrock Lake Term Loan with Lynrock Lake in the aggregate principal amount of $10.1 million, which was used to repay the Car Note issued in February 2024, fully settled its obligations under the Yorkville Note issued on March 4, 2024, and terminated the SEPA with Yorkville by paying $3.0 million in cash and issuing the Yorkville Warrant. Net of these payments, we had $5.4 million of net proceeds for working capital purposes. In addition, on August 26, 2025, we and Lynrock Lake entered into the Lynrock Lake Amended Credit Agreement to add Tranche B in the amount of $5.0 million and increase the aggregate principal amount of the Lynrock Lake Term Loan to $15.1 million. The proceeds of Tranche B were used to repurchase the Yorkville Warrant and Tranche B was subsequently repaid in full, along with repayment premium and accrued interest, on October 6, 2025.

We completed a series of PIPE transactions, where we received cash in exchange for the issuance of shares of common stock plus warrants for the purchase of common stock.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On April 24, 2025, we entered into the First Securities Purchase Agreement for a PIPE investment in an amount of approximately $0.5 million from related persons. We used the net proceeds from the offering for working capital purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On May 12, 2025, we entered into the Second Securities Purchase Agreement for a PIPE investment in an amount of approximately $0.2 million. We used the net proceeds from the offering for working capital purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On September 30, 2025, we entered into the Third Securities Purchase Agreement for a PIPE investment in an amount of approximately $18.2 million, before deducting the offering expenses payable by us. We used the net proceeds from the offering for working capital purposes and to repay Tranche B of the Lynrock Lake Term Loan.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On January 22, 2026, we entered in a Securities Purchase Agreement for the January 2026 Private Placement with the Chairman of our Board of Directors. The aggregate gross proceeds to us from the January 2026 Private Placement was approximately $0.2 million. We intend to use the net proceeds from the offering for working capital purposes.

We entered into several distribution agreements which provided us with MOQs as follow:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On June 18, 2024, as amended on December 11, 2024 and further amended on March 28, 2025, we entered into the Amended NXC Distribution Agreement with NXC, which provides us with MOQs amounting to expected cash inflows of up to $28.5 million in 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On August 21, 2025, we entered into the Gulf Medical Distribution Agreement with GMC, a corporation organized and existing under the laws of Saudi Arabia, for an initial term of three years. Under the terms of the Gulf Medical Distribution Agreement, we granted to GMC the exclusive right to market, advertise and sell the Company's Breast Acoustic CT scanners and the QTI Cloud SaaS platform subscriptions in Saudi Arabia, with MOQs amounting to $11.2 million to $12.3 million in 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On January 19, 2026, we entered into an exclusive distribution agreement for the Company's Breast Acoustic CT scanners and QTI Cloud SaaS Platform in the UAE with Al Naghi Medical Co., a leading distributor of medical devices. The agreement provides for MOQs of seven scanners in 2026 (starting in the second quarter), increasing to 16 scanners in 2027 and 20 scanners in 2028, for a total minimum of 43 scanners representing revenue of more than $24 million.

We believe that the additional cash received from the Lynrock Lake Term Loan, the PIPE investments, and the additional expected revenue from MOQs per the Amended NXC Distribution Agreement and new distribution partners in the Gulf

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

region, Gulf Medical and Al Naghi Medical Co., will be sufficient to fund our current operating plan for at least the next 12 months.

Our future capital requirements will depend on many factors, including our growth rate, the timing and extent of our spending to support research and development activities, the timing and cost of establishing additional sales and marketing capabilities, and the timing and cost to introduce new and enhanced products. In the event that additional financing is required from outside sources, we may not be able to raise it on terms acceptable to us or at all. Any additional debt financing obtained by us in the future could also involve restrictive covenants relating to our capital-raising activities and other financial and operational matters, which may make it more difficult for us to obtain additional capital and to pursue business opportunities, including potential acquisitions. Additionally, if we raise additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, our existing stockholders could suffer significant dilution in their percentage ownership of the Company, and any new equity securities we issue could have rights, preferences and privileges senior to those of holders of our common stock. If we are unable to obtain adequate financing or financing on terms satisfactory to us when we require it, our ability to continue to grow or support our business and to respond to business challenges could be significantly limited.

***Lynrock Lake Term Loan***

On February 26, 2025, we entered into the Lynrock Lake Credit Agreement that provides the Lynrock Lake Term Loan with Lynrock Lake. The Lynrock Lake Credit Agreement is secured by a first priority lien on substantially all of our assets and provides for a term loan in the aggregate principal amount of $10.1 million at an interest rate of 10.0% per annum, compounded quarterly. The maturity date of the Lynrock Lake Credit Agreement is March 31, 2027. The Lynrock Lake Term Loan shall be repaid on the maturity date in an amount equal to the aggregate principal amount outstanding, together with all accrued and unpaid principal and any outstanding and payable fees.

Subject to the payment of the Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement), we may at any time prior to the maturity date optionally prepay the term loan, in full or in part, upon irrevocable written notice of three business days prior to the proposed prepayment; provided that if such prepayment is to be funded with the proceeds of a refinancing or disposition, such notice of prepayment may be revoked if the financing or disposition is not consummated; provided further, that any such prepayment made in connection with, or in anticipation of, a Change of Control (as defined in the Lynrock Lake Credit Agreement) will also be subject to a prepayment premium equal to 20% of the amount of principal being prepaid (the "***Prepayment Premium***"). Partial prepayments of the term loan shall be in an aggregate principal amount of $0.3 million or a whole multiple thereof.

Subject to the payment of the Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement), at the option of Lynrock Lake, we will make mandatory repayments of the term loan upon the following occurrences:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If on any date we or any of our subsidiaries will receive any cash proceeds from any Extraordinary Receipt (as defined in the Lynrock Lake Credit Agreement) in an amount equal to or exceeding $0.3 million in the aggregate, we shall prepay the term loan within 5 business days of receipt of such cash proceeds, in an amount equal to 100% percent of the cash proceeds of such Extraordinary Receipt;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If any indebtedness will be incurred by us or any subsidiary thereof (excluding any indebtedness that the Lynrock Lake Credit Agreement permits us to incur), an amount equal to 100% of the net cash proceeds thereof shall be applied on the date of incurrence or receipt toward the prepayment of the term loan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• If on any date we or any of our subsidiaries will receive net cash proceeds in an amount equal to or exceeding (i) $0.3 million in any single transaction or series of related transactions or (ii) $0.3 million in the aggregate for all transactions during the term of the Lynrock Lake Credit Agreement from any Asset Sale (as defined in the Lynrock Lake Credit Agreement) or Recovery Event (as defined in the Lynrock Lake Credit Agreement) then we or our subsidiary shall prepay the term loan, on or prior to the date which is five business days after the date of the realization or receipt by us or our subsidiary in an amount equal to 100% percent of such proceeds; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Subject to the payment of the Prepayment Premium in addition to the Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement), in the event that a Change of Control (as defined in the Lynrock Lake Credit Agreement) will occur, we shall prepay all of the outstanding term loan, on or prior to the date which is two business days after the date of such Change of Control (as defined in the Lynrock Lake Credit Agreement).

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

There are no requirements to make any prepayment in the event that we sell any of our capital stock. In addition, at the option of Lynrock Lake, we shall also make mandatory repayments of the term loan on a monthly basis, no later than five business days after the end of each month (provided that such date for payment is prior to the maturity date), if we or our subsidiaries receive payment of accounts receivable on or after January 1, 2026, in an amount equal to 15% percent of the aggregate amount of payments of accounts receivable actually received during such prior month, net of any cost of collection incurred not in the ordinary course of business. No Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement) or Prepayment Premium is due or payable on any such mandatory prepayment as a result of receipt of accounts receivable on or after January 1, 2026. As of December 31, 2025, Lynrock Lake has not elected the repayment option in the amount equal to 15% percent of the aggregate amount of payments of accounts receivable actually received on or after January 1, 2026.

Furthermore, in connection with the Lynrock Lake Term Loan, we issued to Lynrock Lake, pursuant to the terms of a Warrant to Purchase common stock, the Lynrock Lake Warrant to purchase 20,333,623 shares of common stock at an exercise price of $1.20 per share. The Lynrock Lake Warrant is exercisable until February 26, 2035. Lynrock Lake may cashless exercise the Lynrock Lake Warrant. The Lynrock Lake Warrant is also subject to anti-dilution adjustments to the exercise price and the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant in the event that we issue shares of common stock (or derivative securities) at a price that is either less than the $1.20 exercise price or the fair market value of a share of common stock from the immediately prior trading day. The fair value of the Lynrock Warrant at issuance amounted to $16.5 million.

Upon issuance of the Lynrock Lake Term Loan, we recorded a loss of $6.6 million, including debt issuance costs of $0.2 million, in other expense, net within the consolidated statements of operations and comprehensive loss for the year ended December 31, 2025

On August 26, 2025, we entered into the Lynrock Lake Amended Credit Agreement to add Tranche B in the amount of $5.0 million to the loan and increase the aggregate principal amount of the Lynrock Lake Term Loan to $15.1 million. The proceeds of Tranche B were used to repurchase the Yorkville Warrant for an aggregate price of $5.0 million. On October 6, 2025, the Company repaid Tranche B, plus accrued interest and a 6% premium.

As of December 31, 2025, the outstanding amount of the Lynrock Lake Term Loan was $0.7 million, net of the unamortized debt discount of $9.4 million, and accrued interest of $0.9 million.

***Related Party Convertible Notes Payable***

Our three convertible notes to three of our stockholders for advances up to $3.5 million in principal issued in July 2020 (the "***2020 Notes***") bear annual interest of 5% on any amounts drawn. The additional note issued in March 2022 as part of the 2020 Notes, has an annual interest rate of 8%. All principal and interest payments were initially due on or before July 1, 2025. In connection with the issuance of the Lynrock Lake Term Loan, on February 26, 2025, the maturity date on these convertible notes payable was extended to October 21, 2027.

The 2020 Notes are convertible, at the holder's option, into shares of our common stock at the lower of $43.77 per share or the offering price in a financing of at least $5.0 million in equity from unaffiliated parties. As of December 31, 2025, an aggregate of 89,303 shares of common stock would be issued if the entire principal and interest under the 2020 Notes was converted.

As of December 31, 2025 and 2024, the outstanding amount of the 2020 Notes was $3.2 million and $3.1 million, respectively, and accrued interest was $0.7 million and $0.6 million, respectively.

***Related Party Working Capital Loan***

On May 3, 2023, we issued a promissory note (the "***Working Capital Note***") to a stockholder for a principal amount of $0.3 million. The Working Capital Note was subsequently amended and restated six times on June 12, 2023 to add an additional principal amount of $0.1 million, August 15, 2023 to add an additional principal amount of $0.1 million, August 29, 2023 to add an additional principal amount of $0.1 million, September 12, 2023 to add an additional principal amount of $0.1 million, September 15, 2023 to add an additional principal amount of $0.1 million, and October 26, 2023 to add an additional principal amount of $0.1 million, for an aggregate principal amount outstanding as of December 31, 2025 and 2024 under the Working Capital Note of $0.7 million. The Working Capital Note was issued to provide the Company with additional working capital during the period prior to consummation of the Business Combination Agreement with

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

GigCapital5. The Working Capital Note is interest-free and originally matured on the earlier of (i) the date on which the Company consummated the Business Combination with GigCapital5; (ii) the date the Company winds up; or (iii) December 31, 2023. The Working Capital Note may be prepaid without penalty. On March 4, 2024, the holder of the Working Capital Note agreed to extend and subordinate the promissory note pursuant to and in accordance with the terms of the Business Combination Agreement. Effective on the closing of the Business Combination, the Working Capital Note cannot be repaid prior to the repayment or conversion of the Yorkville Note received from Yorkville. In connection with the issuance of the Lynrock Lake Term Loan, on February 26, 2025, the maturity date on the Working Capital Note was extended to October 1, 2027.

***Net Cash Used In Operating Activities***

Net cash used in operating activities was $9.0 million for the year ended December 31, 2025 as compared to $10.0 million for the year ended December 31, 2024. The primary use of our cash was to fund research and development and general and administrative expenses. Net cash used for the year ended December 31, 2025 consisted of a net loss of $21.1 million, adjusted for non-cash expenses primarily including depreciation and amortization of $0.1 million, stock-based compensation of $0.8 million, loss on issuance of the Lynrock Lake Term Loan of $6.6 million, debt extinguishment loss of $2.1 million, debt modification expense of $0.1 million, non-cash interest of $1.2 million, change in fair value of warrant liability of $3.6 million, change in fair value of derivative liability of $0.1 million, change in fair value of earnout liability of $1.8 million. The net change in operating assets and liabilities was primarily due an increase in accounts receivable of $5.7 million, an increase in prepaid expenses and other current assets of $0.3 million, and an increase in inventory of $1.9 million, partially offset primarily by an increase in accounts payable of $2.5 million, an increase in accrued expenses and other current liabilities of $0.4 million, and an increase in other liabilities of $1.1 million.

Net cash used for the year ended December 31, 2024 consisted of a net loss of $9.0 million, adjusted for non-cash expenses including depreciation and amortization of $0.2 million, stock-based compensation of $0.3 million, warrant modification expense of $0.2 million, fair value of common stock issued in exchange for services and in connection with non-redemption agreements of $3.7 million, a loss of $0.2 million related to issuance of common stock in connection with a stock subscription agreement, non-cash interest of $3.6 million, a decrease in fair value of warrant liability of $0.2 million, a decrease in fair value of derivative liability of $4.8 million, a decrease in fair value of earnout liability of $3.2 million. The net change in operating assets and liabilities was primarily due to an increase in accounts receivable of $0.1 million, an increase in prepaid expenses and other current assets of $0.2 million, a decrease in accounts payable of $2.0 million, a decrease in accrued expenses and other liabilities of $0.8 million, partially offset by a decrease in inventory of $1.5 million, and an increase in other liabilities of $0.2 million.

***Net Cash used in Investing Activities***

Net cash used in investing activities was $0.1 million for the year ended December 31, 2025 as compared to $0.1 million for the year ended December 31, 2024. The use of net cash used in investing activities for both periods was related to the purchase of property and equipment.

***Net Cash provided by Financing Activities***

During the year ended December 31, 2025, net cash provided by financing activities was $18.4 million primarily due to $14.9 million of net proceeds received from issuance of long-term debt related to the Lynrock Lake Term Loan, net proceeds from the sale of common stock and warrants of $17.6 million, proceeds from warrant exercises of $0.6 million,

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

and proceeds from stock option exercises of $0.1 million, partially offset by the repayment of long-term debt of $9.7 million related to the Yorkville Note and Cable Car Note and warrant repurchase payment of $5.0 million to Yorkville.

During the year ended December 31, 2024, net cash provided by financing activities was $11.1 million, primarily due to $10.5 million of net proceeds received from issuance of long-term debt related to the Yorkville Pre-Paid Advance and the Cable Car Note, $1.0 million of net proceeds from the sale of common stock, cash proceeds of $0.5 million received from issuance of common stock pursuant to a subscription agreement, and net proceeds of $1.2 million received from the business combination of QT Imaging, Inc. and GigCapital5, Inc. (the "***Merger***"), partially offset by repayment of long-term debt of $1.3 million and repayment of bridge loans of $0.8 million.

**Future Funding Requirements** 

We expect to incur increased significant expenses in connection with our ongoing activities, particularly as we continue the research and development of our products and product candidates, seek expanded regulatory clearances for the QT Breast Scanner, and build a U.S. sales and marketing team. As part of the effort to build the sales and marketing capabilities in the United States, QT Imaging entered into the Amended NXC Distribution Agreement, pursuant to which QT Imaging appointed NXC as the exclusive agent for the sale of the QT Breast Scanner in the U.S. and U.S. territories. We expect to incur additional costs associated with operating as a public company. Our future funding requirements, both short-and long-term, will depend on many factors, including, without limitation:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Having the cash to repay our debt obligations as they come due;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expand our current manufacturing operations and expand existing and build new partnerships with contract manufacturing third-party vendors;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Purchase inventory for our planned shipments;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Expand or enhance our distribution with third-party distribution channels outside of the U.S.;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The progress and results of our trials and interpretation of those results by the FDA (and other regulatory authorities, as required);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Seek regulatory clearances for product candidates and expanded regulatory clearance for the QT Breast Scanner;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The cost of operating as a public company, including hiring additional personnel as well as increased director and officer insurance premiums, audit and legal fees, investor relations fees and expenses related to compliance with public company reporting requirements under the Exchange Act and rules implemented by the SEC and Nasdaq; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending our intellectual property-related claims.

We plan to continue to incur substantial costs in order to conduct research and development activities necessary to develop a commercialized product. Additional capital will be needed to undertake these activities and commercialization efforts. We intend to raise such capital through the issuance of additional equity, borrowings and potential strategic alliances with other companies. If we raise additional capital through debt financing, we may be subject to covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If such financing is not available at adequate levels or on acceptable terms, we could be required to significantly reduce operating expenses and delay, reduce the scope of or eliminate some of our development programs or our commercialization efforts, out-license intellectual property rights to our product candidates and sell unsecured assets, or a combination of the foregoing, any of which may have a material adverse effect on our business, results of operations, financial condition and/or our ability to fund our scheduled obligations on a timely basis, or at all.

Because of the numerous risks and uncertainties associated with manufacturing, research, development and commercialization of products, we are unable to estimate the exact amount of our operating capital requirements. Our future funding requirements will depend on, and could increase significantly as a result of, many factors, including, without limitation:

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The timing, receipt and amount of revenues from the sales of the QT Breast Scanner and related products and services, or any future approved or cleared products and product candidates, if any;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The cost of future activities, including product sales, medical affairs, marketing, manufacturing and distribution for the QT Breast Scanner;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The costs, timing, and outcomes of regulatory review of applications for expanded clearances for the QT Breast Scanner;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The scope, progress, results and costs of researching, developing and manufacturing our product candidates or any future product candidates, and conducting studies and clinical trials;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The timing of, and the costs involved in, obtaining regulatory approvals or clearances for our product candidates or any future product candidates;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The cost of manufacturing our product candidates or any future product candidates and any products we successfully commercialize, including costs associated with building out our manufacturing capabilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The cost and time needed to attract and retain skilled personnel to support our continued growth;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Our ability to establish and maintain strategic collaborations, licensing or other arrangements and the financial terms of any such agreements that we may enter into; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The costs associated with being a public company.

Additionally, our operating plans may change, and we may need additional funds to meet operational needs and capital requirements for future trials and other research and development activities. Until such time, if ever, as we can generate substantial product revenue, we expect to finance our cash needs through a combination of public or private equity offerings, debt financings, collaborations, strategic partnerships or marketing, distribution or licensing arrangements with third parties. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our stockholders may be materially diluted, and the terms of such securities could include liquidation or other preferences that adversely affect the rights of our stockholders. Debt financing and preferred equity financing, if available, may involve agreements that include restrictive covenants that limit our ability to take specified actions, such as incurring additional debt, making capital expenditures or declaring dividends. In addition, debt financing would result in increased fixed payment obligations.

If we raise funds through collaborations, strategic partnerships or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or products, or grant licenses on terms that may not be favorable to us.

If we are unable to raise additional funds when needed, we may be required to delay, reduce, or eliminate our product development or future commercialization efforts, or grant rights to develop and market products that we would otherwise prefer to develop and market ourselves.

Our ability to continue as a going concern is dependent upon our ability to successfully accomplish these plans and secure sources of financing and attain profitable operations. If we are unable to obtain adequate capital, we could be forced to cease operations. See the section entitled "*Risk Factors*" for additional factors and risks associated with our capital requirements.

**Off-Balance Sheet Arrangements** 

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements.

**Contractual Obligations** 

We lease our operating facilities in Novato, California, under a non-cancelable operating lease through May 31, 2027. There are no options or rights to extend the term of this lease.

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

**Contingencies** 

***Litigation***

We are subject to occasional lawsuits, investigations and claims arising out of the normal course of business. As of the date the consolidated financial statements were available to be issued, management is not aware of any pending claims that will have a material impact on our consolidated financial statements.

**Emerging Growth Company** 

We are an emerging growth company ("***EGC***"), as defined in the Jumpstart Our Business Startups Act of 2012 ("***JOBS Act***"). Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We have elected to use this extended transition period for complying with new or revised accounting standards that have different effective dates for public and private companies until the earlier of the date we (i) are no longer an emerging growth company, or (ii) affirmatively and irrevocably opt out of the extended transition period provided in the JOBS Act. As a result, our consolidated financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

In addition, we intend to rely on the other exemptions and reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an EGC, we intend to rely on such exemptions, we are not required to, among other things: (i) provide an auditor's attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act; (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd- Frank Wall Street Reform and Consumer Protection Act; (iii) comply with any requirement that may be adopted by the Public Company Accounting Oversight Board (United States) regarding mandatory audit firm rotation or a supplement to the auditor's report providing additional information about the audit and the financial statements (auditor discussion and analysis); and (iv) disclose certain executive compensation-related items such as the correlation between executive compensation and performance and comparisons of the Chief Executive Officer's compensation to median employee compensation.

We will remain an EGC under the JOBS Act until the earliest of (i) the last day of our first fiscal year following the fifth anniversary of the Closing of the Business Combination, (ii) the last date of our fiscal year in which we have total annual gross revenue of at least $1.235 billion, (iii) the date on which we are deemed to be a "large accelerated filer," as defined in Rule 12b-2 promulgated under the Exchange Act, or (iv) the date on which we have issued more than $1.0 billion in non-convertible debt securities during the previous three-years.

**Critical Accounting and Estimates** 

The discussion and analysis of our financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with GAAP. The preparation of these consolidated financial statements requires us to make estimates, judgments and assumptions that affect the reported amounts of assets, liabilities, revenues, and expenses and the related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate these estimates, and assumptions, including those related to revenue, inventories and income taxes, among others. Our estimates are derived from historical experience, current conditions and various other assumptions that we believe to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities as well as identifying and assessing the accounting treatment with respect to commitments and contingencies. Our actual results may materially differ from these estimates. In addition, any change in these estimates or their underlying assumptions could have a material adverse effect on our operating results.

We believe that the accounting policies discussed below are critical to the understanding of our historical and future performance, and these accounting policies involve a significant degree of judgment and complexity. For further information, see the accompanying notes to our audited consolidated financial statements.

***Revenue Recognition***

Revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration we expect to be entitled to receive in exchange for these goods or services.

We determine revenue recognition through the following steps:

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

1.*Identification of the contract, or contracts, with a customer:*

We consider the terms and conditions of the contract in identifying the contracts. We determine a contract with a customer to exist when the contract is approved, each party's rights regarding the goods or services to be transferred can be identified, the payment terms for the goods or services can be identified, it has been determined the customer has the ability and intent to pay, and the contract has commercial substance. At contract inception, we evaluate whether two or more contracts should be combined and accounted for as a single contract and whether the combined or single contract includes more than one performance obligation. We apply judgment in determining the customer's ability and intent to pay, which is based on a variety of factors, including the customer's historical payment experience or, in the case of a new customer, credit and financial information pertaining to the customer.

2.*Identification of the performance obligations in the contract:*

Performance obligations promised in a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the goods or services either on its own or together with other resources that are readily available from third parties or from us, and are distinct in the context of the contract, whereby the transfer of the goods or services is separately identifiable from other promises in the contract. Our performance obligations consist of (i) product sales, (ii) maintenance contracts and (iii) other services including training.

3.*Determination of the transaction price:* 

The transaction price is determined based on the consideration to which we expect to be entitled in exchange for transferring goods or services to the customer. Variable consideration is included in the transaction price if, in our judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. Our contracts do not contain a significant financing component.

4.*Allocation of the transaction price to the performance obligations in the contract:* 

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price.

5.*Recognition of revenue when, or as a performance obligation is satisfied:* 

For product sales and services, revenue is recognized at the time the related performance obligation is satisfied by transferring the control of the promised goods or services to a customer, in an amount that reflects the consideration that we expect to receive in exchange for those goods or services. Training and maintenance services are generally recognized upon invoicing in amounts that correspond directly with the value to the customer of the performance completed to date which primarily includes professional service arrangements entered on a time and materials basis.

***Inventory***

Inventory is stated at the lower of cost or net realizable value. Cost is determined using the weighted- average cost method. We periodically reviews the value of items in inventory and provides write-offs of inventory that is obsolete. Appropriate consideration is given to obsolescence, excessive levels, deterioration, and other factors in evaluating net realizable value. Once inventory has been written down below cost, it is not subsequently written up.

***Income Taxes***

Deferred tax assets and liabilities are determined based on the differences between financial reporting and the tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Deferred tax assets be reduced by a valuation allowance if it is more-likely-than-not that some or all of the deferred tax asset will not be realized. We annually evaluate the realizability of deferred tax assets by assessing the valuation allowance and by adjusting the amount of such allowance, if necessary. The factors used to assess the likelihood of realization include our forecast of future taxable income and available tax planning strategies that could be implemented to realize the net deferred tax assets.

We recognize the financial statement benefit of a tax position only after determining that the relevant tax authority would more-likely-than-not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the consolidated financial statements is the largest benefit that has a greater than 50% likelihood

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_7)</u>**

of being realized upon ultimate settlement with the relevant tax authority. In accordance with this accounting policy, we recognize accrued interest and penalties related to unrecognized tax benefits as a component of income tax benefit.

See Note 1 to the audited consolidated financial statements for a discussion of recent accounting pronouncements.

**Report of Independent Registered Public Accounting Firm** 

To the Board of Directors and Stockholders of

QT Imaging Holdings, Inc.

**Opinion on the Consolidated Financial Statements** 

We have audited the accompanying consolidated balance sheets of QT Imaging Holdings, Inc. (a Delaware corporation) and its subsidiaries (the "Company") as of December 31, 2025 and 2024, and the related consolidated statements of operations and comprehensive loss, stockholders' equity (deficit), and cash flows for each of the two years in the period ended December 31, 2025, and the related notes (collectively referred to as the "consolidated financial statements"). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

**Basis for Opinion** 

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company's internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

/s/ BPM LLP

We have served as the Company's auditor since 2022.

(1)*Amounts and share amounts as of December 31, 2024 differ from those published in prior consolidated financial statements as they were retrospectively adjusted as a result of the Reverse Stock Split (as described below in Note 1, The Company and Summary of Significant Accounting Policies). Specifically, the number of shares of common stock outstanding during periods before the Reverse Stock Split are divided by the exchange ratio of 3:1, such that each three shares of common stock were combined and reconstituted into one share of common stock effective October 23, 2025.*

**Notes to Consolidated Financial Statements**

**1. The Company and Summary of Significant Accounting Policies**

***Nature of Operations***

QT Imaging Holdings, Inc. and its subsidiaries (the "***Company***"), formerly known as GigCapital5, Inc. ("***GigCapital5***"), is incorporated in Delaware with headquarters in Novato, California. The Company is a medical device company engaged in research, development, and commercialization of innovative body imaging systems using low frequency sound waves. The Company strives to improve global health outcomes. Its strategy is predicated upon the fact that medical imaging is critical to the detection, diagnosis, and treatment of disease and that it should be safe, affordable, accessible, and centered on the patient's experience. The Company's initial product is a breast imaging system.

On March 4, 2024, QT Imaging, Inc. ("***QT Imaging***"), GigCapital5, and QTI Merger Sub, Inc. ("***QTI Merger Sub***"), pursuant to the terms of the Business Combination Agreement (the "***Business Combination Agreement***") dated December 8, 2022, completed the business combination of QT Imaging and GigCapital5, which was effected by the merger of QTI Merger Sub with and into QT Imaging, with QT Imaging surviving the Merger as a wholly owned subsidiary of GigCapital5 (the "***Merger***," and, together with the other transaction contemplated by the Business Combination Agreement, the "***Business Combination***"). Upon completion of the merger on March 4, 2024, GigCapital5 changed its name to QT Imaging Holdings, Inc. and effectively assumed all of QT Imaging's material operations. Refer to Note 2 - Business Combination for more information regarding the Merger.

***Basis of Presentation***

The accompanying consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("***U.S. GAAP***"). In the opinion of management, the consolidated financial statements contain all adjustments necessary for a fair presentation of the Company's financial position as of the date reported.

The share and per share amounts, prior to the Merger, have been retrospectively restated as shares reflecting conversion at the exchange ratio of approximately 0.3427 established in the Business Combination Agreement.

***Reverse Stock Split***

On August 19, 2025 the Company's stockholders approved an amendment to the Company's Second Amended and Restated Certificate of Incorporation to effect a reverse split of the outstanding shares of the Company's common stock, par value $0.0001 per share, at a specific ratio within a range of 2:1 to 20:1, with the specific ratio to be fixed within this range by the Company's Board of Directors in its sole discretion without further stockholder approval (the "***Reverse Stock Split***"). The Company's Board of Directors fixed the Reverse Stock Split ratio at 3:1, such that each three shares of common stock were combined and reconstituted into one share of common stock effective October 23, 2025. In connection with the Reverse Stock Split, the CUSIP number of the common stock changed to 746962307. The common stock began trading on the OTCQB Venture Market on a reverse split-adjusted basis on October 24, 2025. Except as noted, all share, stock option, warrant, and per share amounts throughout these consolidated financial statements have been retroactively adjusted to reflect this Reverse Stock Split.

***Uplisting to Nasdaq***

Effective January 28, 2026, upon meeting all of the Nasdaq Stock Market LLC ("***Nasdaq***") listing requirements, the Company's common stock was uplisted from the OTCQB Venture Market to the Nasdaq Capital Market and began trading under the ticker symbol "QTI."

***Principles of Consolidation***

The consolidated financial statements include the accounts of QT Imaging Holdings, Inc. and its wholly-owned subsidiaries, QT Imaging and QT Ultrasound Labs, Inc. All intercompany balances and transactions are eliminated in consolidation.

------

***Liquidity***

The Company has incurred net operating losses and negative cash flows from operations since its inception and had an accumulated deficit of $53.0 million as of December 31, 2025. During the year ended December 31, 2025, the Company incurred a net loss of $21.1 million and used $9.0 million of cash in operating activities. The Company expects to continue to incur losses, and its ability to achieve and sustain profitability will depend on the achievement of sufficient revenues to support the Company's cost structure. The Company may never achieve profitability and, unless and until it does, the Company will need to continue to raise additional capital.

On February 26, 2025, the Company entered into a credit agreement (the "***Lynrock Lake Credit Agreement***") that provides a senior secured term loan (the "***Lynrock Lake Term Loan***") with Lynrock Lake Master Fund LP ("***Lynrock Lake***") in the aggregate principal amount of $10.1 million, which was used to repay the secured note purchase agreement (the "***Cable Car Note***") with Funicular Funds, LP ("***Cable Car***") issued in February 2024, fully settled its obligations under the promissory note (the "***Yorkville Note***") issued to YA II PN, LTD ("***Yorkville***") on March 4, 2024, and terminated the Standby Equity Purchase Agreement (the "***SEPA***") with Yorkville by paying $3.0 million in cash and issuing a 5-year warrant to purchase 5,000,071 shares of common stock (the "***Yorkville Warrant***"). Net of these payments, the Company had $5.4 million of net proceeds for working capital purposes. In addition, on August 26, 2025, the Company and Lynrock Lake entered into the First Amendment to the Lynrock Lake Credit Agreement (the "***Lynrock Lake Amended Credit Agreement***") to add an additional tranche of $5.0 million ("***Tranche B***") and increase the aggregate principal amount of the Lynrock Lake Term Loan to $15.1 million. The proceeds of Tranche B were used to repurchase the Yorkville Warrant and Tranche B was subsequently repaid in full, along with the repayment premium and accrued interest, on October 6, 2025. Refer to Note 7 - Long-Term Debt for more information.

During the year ended December 31, 2025, the Company completed a series of Private Investment in Public Entity ("***PIPE***") transactions, where it received cash in exchange for the issuance of shares of common stock plus warrants for the purchase of common stock. Refer to Note 10 - Stockholders' Equity (Deficit) for more information.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On April 24, 2025, the Company entered into a subscription agreement for a PIPE investment in an amount of approximately $0.5 million from related persons. The Company used the net proceeds from the offering for working capital purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On May 12, 2025, the Company entered into a subscription agreement for a PIPE investment in an amount of approximately $0.2 million. The Company used the net proceeds from the offering for working capital purposes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On October 3, 2025, the Company closed a subscription agreement for a PIPE investment (the "***October 2025 Private Placement***") in an amount of approximately $18.2 million, before deducting the offering expenses payable by the Company. The Company used the net proceeds from the offering for working capital purposes and to repay Tranche B of the Lynrock Lake Term Loan.

The Company entered into several distribution agreements which provided the Company with Minimum Order Quantities ("***MOQs***") as follow:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On June 18, 2024, as amended on December 11, 2024 and further amended on March 28, 2025, the Company entered into a Distribution Agreement (the "***Amended NXC Distribution Agreement***") with NXC Imaging, Inc. ("***NXC***"), which provides the Company with MOQs amounting to expected cash inflows of up to $28.5 million in 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On August 21, 2025, the Company entered into a Distribution Agreement (the "***Gulf Medical Distribution Agreement***") with Gulf Medical Co. ("***GMC***"), a corporation organized and existing under the laws of Saudi Arabia, for an initial term of three years. Under the terms of the Gulf Medical Distribution Agreement, the Company granted to GMC the exclusive right to market, advertise and sell the Company's Breast Acoustic CT™ scanners and the QTI Cloud SaaS platform subscriptions in Saudi Arabia, with MOQs amounting to $11.2 million to $12.3 million in 2026 upon regulatory approval from the Saudi Food and Drug Administration ("FDA").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• On January 19, 2026, the Company entered into an exclusive distribution agreement (the "***Al Naghi Distribution Agreement***") for the Company's Breast Acoustic CT™ scanners and QTI Cloud SaaS Platform in the United Arab

------

Emirates (the "***UAE***") with Al Naghi Medical Co., a leading distributor of medical devices. The agreement provides for MOQs of 7 scanners in 2026 (starting in the second quarter), increasing to 16 scanners in 2027 and 20 scanners in 2028, for a total minimum of 43 scanners representing revenue of more than $24 million upon regulatory approval from the UAE FDA, which was received on March 17, 2026.

The Company believes that the additional cash received from the Lynrock Lake Term Loan, the PIPE investments closed in 2025, and the additional expected revenue from MOQs per the Amended NXC Distribution Agreement and new distribution partners in the Gulf region, Gulf Medical and Al Naghi Medical Co., will be sufficient to fund current operating plan for at least the next 12 months.

The Company's future capital requirements will depend on many factors, including the Company's growth rate, the timing and extent of its spending to support research and development activities, purchasing inventory to meet its growth plan, and the timing and cost to enhance commercialized existing products. In the event that additional financing is required from outside sources, the Company may not be able to raise it on terms acceptable to the Company, or at all. Any additional debt financing obtained by the Company in the future could also involve restrictive covenants relating to the Company's capital-raising activities and other financial and operational matters, which may make it more difficult for the Company to obtain additional capital and to pursue business opportunities, including potential acquisitions. Additionally, if the Company raises additional funds through further issuances of equity, convertible debt securities or other securities convertible into equity, its existing stockholders could suffer significant dilution in their percentage ownership of the Company, and any new equity securities the Company issues could have rights, preferences and privileges senior to those of holders of the Company's common stock. If the Company is unable to obtain adequate financing or financing on terms satisfactory to the Company when the Company requires it, the Company's ability to continue to grow or support its business and to respond to business challenges could be significantly limited.

***Use of Estimates***

The preparation of consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues, and expenses and the related disclosure of contingent assets and liabilities. The Company bases its estimates on historical experience and on various other assumptions that it believes to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates. In addition, any change in these estimates or their related assumptions could have an adverse effect on the Company's operating results.

***Business Risk and Concentration of Credit Risk and Supply Risk***

Financial instruments that potentially subject the Company to significant concentrations of credit risk consist primarily of cash and cash equivalents and accounts receivable. The majority of the Company's cash and cash equivalents is invested in U.S. dollar deposits with a reputable bank in the United States. Management believes that minimal credit risk exists with respect to the financial institution that holds the Company's cash and cash equivalents. At times, such cash may be in excess of insured limits established by the Federal Deposit Insurance Corporation.

The Company performs ongoing credit evaluations of its customers and generally does not require collateral for accounts receivable. Payment terms range from cash in advance to 30 days from delivery of products or services but may fluctuate depending on the terms of each specific contract.

Significant customers represent 10% or more of the Company's total revenue or accounts receivable balance for the period ended as of each reporting date. For each significant customer, revenue as a percentage of total revenue and accounts receivable as a percentage of total accounts receivable are as follows:

------

---

| | | | | |
|:---|:---|:---|:---|:---|
| | | | **Revenue** | **Revenue** |
| | **Accounts Receivable** | **Accounts Receivable** | **Year Ended December 31,** | **Year Ended December 31,** |
| | **December 31, 2025** | **December 31, 2024** | **2025** | **2024** |
| **Customers:** |  |  |  |  |
| Customer A | 100% | 13% | 99% | 70% |
| Customer B | \* | \* | \* | 19% |
| Customer C | \* | 12% | \* | \* |
| Customer D | \* | 62% | \* | \* |
|  | 100% | 87% | 99% | 89% |

---

\*Total less than 10% for the period.

There are inherent risks whenever a large percentage of total revenue is concentrated in a limited number of customers. Should a significant customer which is a party to a contract with the Company under which the Company derives revenue terminate or fail to renew its contracts with the Company, in whole or in part, for any reason, or experience significant financial or operating difficulties, it could have a material adverse effect on the Company's financial condition and results of operations. In general, a customer that makes up a significant portion of revenues in one period, may not make up a significant portion in subsequent periods. However, as the Company and NXC have entered into the Amended NXC Distribution Agreement, by which the Company appointed NXC as the exclusive reseller to market, advertise, and resell certain equipment in the U.S. and U.S. territories, the Company expects NXC to make up a significant portion of revenues in each period in which such Amended NXC Distribution Agreement is in effect. Customer A in the concentration table above is NXC. NXC has executed agreements with other distributors across the U.S. territories to strengthen its sales channels. In addition, the Gulf Medical Distribution Agreement will contribute to revenue and expand the Company's sales channel internationally beginning in 2026.

Certain components and services used to manufacture and develop the Company's products are presently available from only one or a limited number of suppliers or vendors. The Company's QT Breast Scanner has more than six hundred components, of which less than five components have such dependencies on limited suppliers or vendors. The loss of any of these suppliers or vendors would potentially require a significant level of hardware and/or software development efforts to incorporate the products or services into the Company's product.

***Cash and Cash Equivalents***

The Company considers all short-term investments with a maturity of three months or less when purchased to be cash equivalents.

***Restricted Cash and Cash Equivalents***

Restricted cash and cash equivalents is comprised of cash held in an account subject to a collateral agreement to be used for the Company's corporate credit card program.

***Accounts Receivable***

Accounts receivable are carried at the amount due. Accounts receivable are written off when management deems all realistic efforts to collect the amount outstanding have been exhausted. A provision for credit losses is estimated by management based on evaluations of its historical bad debt and current collection experience. As of December 31, 2025 and 2024, an allowance for credit losses was not required. Write-offs of accounts receivable were not significant during the years ended December 31, 2025 and 2024.

***Inventory***

Inventory is stated at the lower of cost or net realizable value. Cost is determined using the weighted-average cost method. The Company periodically reviews the value of items in inventory and provides write-offs of inventory that is obsolete.

------

Appropriate consideration is given to obsolescence, excessive levels, deterioration, and other factors in evaluating net realizable value. Once inventory has been written down below cost, it is not subsequently written up.

***Property and Equipment, Net***

Property and equipment, net are recorded at cost, less accumulated depreciation. Expenditures for major additions and improvements are capitalized and minor replacements, maintenance, and repairs are charged to current operations as incurred. When property and equipment are retired or otherwise disposed of, the cost and accumulated depreciation are removed from the accounts and any resulting gain or loss is included in the results of operations for the respective period. Depreciation is provided over the estimated useful lives of the related assets using the straight-line method. Leasehold improvements are amortized over the lesser of the term of the related lease or the estimated useful lives of the assets.

***Leases***

The Company primarily enters into leases for office space that are classified as operating leases. The Company determines if an arrangement is or contains a lease at inception. The Company accounts for leases by recording right-of-use ("ROU") assets and lease liabilities on the consolidated balance sheets in the captions operating lease right-of-use assets, net and operating lease liabilities, respectively. The lease term includes the non-cancelable period of the lease plus any additional periods covered by an option to extend that the Company is reasonably certain to exercise. The Company's leases do not include substantial variable payments based on an index or rates. The Company's lease agreements do not contain any significant residual value guarantees or material restrictive covenants.

The Company's leases do not provide a readily determinable implicit discount rate. The Company's incremental borrowing rate is estimated to approximate the interest rate on a collateralized basis with similar terms and payments, and in similar economic environments. Operating lease ROU assets and liabilities are recognized at their commencement date based on the present value of lease payments over the lease term. The lease payments related to the next 12 months are included in operating lease liabilities, current on the consolidated balance sheets. The Company recognizes a single lease cost on a straight-line basis over the term of the lease, and the Company classifies all cash payments within operating activities in the consolidated statements of cash flows.

The Company did not have any finance leases as of December 31, 2025 and 2024.

***Intangible Assets, Net***

The Company's intangible assets are comprised of patents with a useful life of 12 years. Patents are amortized on a straight-line basis over their useful life. Amortization expense for intangible assets was $0.1 million for the year ended December 31, 2024. The Company had no intangible assets, net as of December 31, 2025 and 2024.

***Long-Lived Assets***

Long-lived assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset may not be recoverable. If circumstances require a long-lived asset be tested for possible impairment, the Company first compares undiscounted cash flows expected to be generated by an asset to the carrying value of an asset. If the carrying value of the long-lived asset is not recoverable on an undiscounted cash flow basis, impairment is recognized to the extent that the carrying value exceeds its fair value. Fair value is determined through various valuation techniques including discounted cash flow models, quoted market values, and third-party independent appraisals, as considered necessary. Management has reviewed the Company's long-lived assets and recorded no impairment charge for the years ended December 31, 2025 and 2024.

***Fair Value Measurements***

The Company applies the requirements of the fair value measurements framework, which establishes a hierarchy for measuring fair value and requires enhanced disclosures about fair value measurements. The fair value measurement guidance clarifies that fair value is an exit price, representing the amount that would be received to sell an asset or paid to

------

transfer a liability in an orderly transaction between market participants at the measurement date. The fair value measurement guidance also requires disclosure about how fair value is determined for assets and liabilities and establishes a hierarchy in which these assets and liabilities must be grouped based on significant levels of inputs.

***Debt and Debt Issuance Costs***

The Company evaluates its financial instruments to determine if they are freestanding financial instruments. The Company also evaluates its convertible debt for embedded derivatives. Embedded provisions (like conversion options) are assessed to determine if they qualify as embedded derivatives that require separate accounting.

Debt issuance costs are recorded as a reduction to the carrying amount of the debt and are amortized to interest expense using the effective interest method. Debt is classified as short-term or long-term based on the term of the note.

***Revenue Recognition***

Revenue is recognized when a customer obtains control of promised goods or services. The amount of revenue recognized reflects the consideration the Company expects to be entitled to receive in exchange for these goods or services.

The Company determines revenue recognition through the following steps:

1)Identification of the contract, or contracts, with a customer

The Company considers the terms and conditions of the contract in identifying the contracts. The Company determines a contract with a customer to exist when the contract is approved, each party's rights regarding the goods or services to be transferred can be identified, the payment terms for the goods or services can be identified, it has been determined the customer has the ability and intent to pay, and the contract has commercial substance. At contract inception, the Company will evaluate whether two or more contracts should be combined and accounted for as a single contract and whether the combined or single contract includes more than one performance obligation. The Company applies judgment in determining the customer's ability and intent to pay, which is based on a variety of factors, including the customer's historical payment experience or, in the case of a new customer, credit and financial information pertaining to the customer.

2)Identification of the performance obligations in the contract

Performance obligations promised in a contract are identified based on the goods or services that will be transferred to the customer that are both capable of being distinct, whereby the customer can benefit from the goods or services either on its own or together with other resources that are readily available from third parties or from the Company, and are distinct in the context of the contract, whereby the transfer of the goods or services is separately identifiable from other promises in the contract. The Company's performance obligations consist of (i) product sales, (ii) maintenance contracts, and (iii) other services including training.

3)Determination of the transaction price

The transaction price is determined based on the consideration to which the Company expects to be entitled in exchange for transferring goods or services to the customer. Variable consideration is included in the transaction price if, in the Company's judgment, it is probable that a significant future reversal of cumulative revenue under the contract will not occur. The Company's contracts do not contain a significant financing component.

4)Allocation of the transaction price to the performance obligations in the contract

If the contract contains a single performance obligation, the entire transaction price is allocated to the single performance obligation. Contracts that contain multiple performance obligations require an allocation of the transaction price to each performance obligation based on a relative standalone selling price.

------

5)Recognition of revenue when, or as a performance obligation is satisfied

For product sales and services, revenue is recognized at the time the related performance obligation is satisfied by transferring the control of the promised goods or services to a customer, in an amount that reflects the consideration that the Company expects to receive in exchange for those goods or services. Training and maintenance services are generally recognized upon invoicing in amounts that correspond directly with the value to the customer of the performance completed to date which primarily includes professional service arrangements entered on a time and materials basis.

Substantially all of the revenue recognized by the Company during the years ended December 31, 2025 and 2024 was recognized at a point in time.

***Shipping and Handling Costs***

Shipping and handling activities are typically performed before the customer obtains control of the goods, and the related costs are therefore expensed as incurred. Shipping and handling costs are included in cost of revenue in the accompanying consolidated statements of operations and comprehensive loss. Shipping and handling costs incurred for inventory purchases are expensed in cost of revenue when sold.

***Product Warranty***

The Company's products sold to customers are generally subject to warranties up to twelve months, which provides for the repair or replacement of products, at the Company's option, that fail to perform with stated specifications. The Company estimates future warranty obligations related to those products. To date, product warranty claims have not been significant.

***Research and Development Costs***

Research and development costs incurred by the Company include salaries, purchased services, operating materials and supplies, depreciation, and amortization, and are expensed as incurred.

***Advertising***

Advertising and promotion costs are expensed as incurred. Advertising expenses were not significant for the years ended December 31, 2025 and 2024.

***Grant Income***

Periodically, the Company is awarded grants on a cost reimbursement basis. Costs are expensed when incurred and reimbursable on a monthly or quarterly basis with the offset booked as a contra-expense to the applicable functional area in the consolidated statements of operations and comprehensive loss.

***Income Taxes***

Deferred tax assets and liabilities are determined based on the differences between financial reporting and the tax basis of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. Deferred tax assets may be reduced by a valuation allowance if it is more-likely-than-not that some or all of the deferred tax asset will not be realized. The Company annually evaluates the realizability of deferred tax assets by assessing the valuation allowance and by adjusting the amount of such allowance, if necessary. The factors used to assess the likelihood of realization include the Company's forecast of future taxable income and available tax planning strategies that could be implemented to realize the net deferred tax assets.

The Company recognizes the financial statement benefit of a tax position only after determining that the relevant tax authority would more-likely-than-not sustain the position following an audit. For tax positions meeting the more-likely-than-not threshold, the amount recognized in the consolidated financial statements is the largest benefit that has a greater

------

than 50% likelihood of being realized upon ultimate settlement with the relevant tax authority. In accordance with this accounting policy, the Company recognizes accrued interest and penalties related to unrecognized tax benefits as a component of income tax benefit. There were no accrued interest and penalties during the years ended December 31, 2025 and 2024.

***Stock-Based Compensation***

Stock-based compensation cost is measured at the grant date based on the fair market value of the award. Stock-based compensation is recognized as expense on a ratable basis over the requisite service period of the award. Forfeitures are recorded as they occur.

The Company values stock options using the Black-Scholes option pricing model. This model requires the use of highly subjective and complex assumptions which determine the fair value of stock-based awards, including the option's expected term, stock price volatility and risk-free interest rates. The Company estimates the grant-date fair value of its restricted stock units ("RSUs") based on the closing price of the Company's common stock on the date of grant.

***Comprehensive Loss***

Comprehensive loss is defined as the change in the equity of a business enterprise during a period from transactions and other events and circumstances from non-owner sources. Comprehensive loss was equal to net loss for the years ended December 31, 2025 and 2024.

***Net Loss per Share***

Basic net loss per share is calculated by dividing the net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration for potentially dilutive securities. Diluted net loss per share is computed by dividing the net loss attributable to common stockholders by the weighted-average number of common shares and potentially dilutive common share equivalents outstanding for the period determined using the treasury-stock and if-converted methods. For the purposes of the diluted net loss per share calculation, common stock equivalents are considered to be potentially dilutive securities.

Reconciliation of net loss per share for the years ended December 31, 2025 and 2024 was as follows:

---

| | | |
|:---|:---|:---|
| *(in thousands, except per share data)* | **Year Ended December 31,** | **Year Ended December 31,** |
|  | **2025** | **2024** |
| Net loss and comprehensive loss attributable to QT Imaging Holdings, Inc. | $(21083) | $(8985) |
| Less: deemed dividend related to the modification of equity classified warrants |  | (5186) |
| Net loss and comprehensive loss attributable to common stockholders | $(21083) | $(14171) |
| Weighted-average number of common shares used in computing net loss per share<sup>(1)</sup> | 10476 | 6659 |
| Net loss per share - basic and diluted<sup>(1)</sup> | $(2.01) | $(2.13) |

---

------

The following securities were excluded from the calculation of net loss per share because the inclusion would be anti-dilutive as of December 31, 2025 and 2024:

---

| | | |
|:---|:---|:---|
| *(in thousands)* | **December 31, 2025** | **December 31, 2024** |
| Common stock warrants<sup>(1)(2)</sup> | 34307 | 9422 |
| Potential shares from Pre-Paid Advance<sup>(1)</sup> |  | 5664 |
| Merger consideration earnout shares<sup>(1)</sup> | 1000 | 2000 |
| Potential shares from Cable Car Note<sup>(1)</sup> |  | 250 |
| Potential shares from convertible notes<sup>(1)</sup> | 89 | 84 |
| RSUs outstanding | 220 |  |
| Options outstanding<sup>(1)(3)</sup> | 1224 | 652 |
|  | 36840 | 18072 |

---

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)*Amounts as of December 31, 2024 differ from those published in prior consolidated financial statements as they were retrospectively adjusted as a result of the Reverse Stock Split (as described in Note 1, The Company and Summary of Significant Accounting Policies). Specifically, the number of potential common shares outstanding during the periods before the Reverse Stock Split are divided by the exchange ratio of 3:1, such that each three shares of potential common stock were combined and reconstituted into one share of potential common stock effective October 23, 2025.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*(2)Warrants issuable for little or no cash consideration are considered outstanding common shares and included in the computation of basic net loss per share. As such, for the year ended December 31, 2025, the Company included pre-funded common stock warrants in its computation of net loss per share and thus excluded them from the table above. These warrants were issued in October 2025 with an exercise price of $0.0003 per pre-funded warrant (See Note 10 – Stockholders' Equity (Deficit) for additional information).*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;*(3)The options outstanding as of December 31, 2024 were revised by 88,000 from the amount previously reported in the Annual Report on Form 10-K for the year ended December 31, 2024. The effect on stock-based compensation was immaterial.*

***Fair Value of Financial Instruments***

The fair value of the Company's financial instruments, including cash equivalents, accounts receivable, prepaid expenses and other current assets, accounts payable, and accrued expenses and other current liabilities approximate their fair values because of the relatively short maturity of these instruments. The carrying value of the Company's borrowings and lease liabilities approximates fair value based on current rates offered to the Company for instruments with similar terms.

***Recently Issued Accounting Pronouncements Not Yet Adopted***

In December 2023, the Financial Accounting Standard Board ("***FASB***") issued Accounting Standards Update ("***ASU***") 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures, which requires disclosure of specific categories in the effective tax rate reconciliation and additional information for reconciling items that meet a quantitative threshold and further disaggregation of income taxes paid for individually significant jurisdictions. This guidance is effective on a prospective or retrospective basis for annual periods beginning after December 15, 2025 for the Company, with early adoption permitted. The Company will adopt this guidance for the fiscal year ending December 31, 2026 on a prospective basis. The adoption of this guidance will not have an impact on the Company's consolidated financial position, results of operations, or cash flows, as the amendments related solely to disclosures.

In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. The standard requires that public business entities disclose additional information about specific expense categories in the notes to financial statements for interim and annual reporting periods. The standard will become effective for the fiscal year ended December 31, 2027 and interim condensed consolidated financial statements thereafter and may be applied prospectively to periods after the adoption date or retrospectively for all prior periods presented in the financial statements, with early adoption permitted. The Company is currently evaluating the impact of this guidance on the disclosures within its consolidated financial statements.

------

In November 2024, the FASB issued ASU 2024-04, Debt—Debt with Conversion and Other Options (Subtopic 470-20): Induced Conversions of Convertible Debt Instruments. This standard clarifies the requirements for determining whether certain settlements of convertible debt instruments should be accounted for as an induced conversion and the application of the induced conversion guidance to a conversion debt instrument. It also clarifies that the incorporation, elimination, or modification of a daily volume-weighted average price ("***VWAP***") formula does not automatically cause a settlement to be accounted for as an extinguishment. This standard will become effective on a prospective or retrospective basis for interim reporting periods and annual periods beginning after December 15, 2025. Early adoption is permitted. The Company is currently evaluating the impact of this guidance on its consolidated financial statements.

In July 2025, the FASB issued ASU 2025-05, Measurement of Credit Losses for Accounts Receivable and Contract Assets, which provides a practical expedient to measure credit losses on accounts receivable and contract assets. The ASU is effective for annual periods beginning after December 15, 2025, and interim periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the timing of the adoption and the impact of the new standard on its consolidated financial statements and related disclosures.

In September 2025, the FASB issued ASU 2025-07, Derivatives and Hedging (Topic 815) and Revenue from Contracts with Customers (Topic 606): Derivatives Scope Refinements and Scope Clarification for Share-Based Noncash Consideration from a Customer in a Revenue Contract. This standard provides a scope exception to exclude from derivative accounting non-exchange-traded contracts with underlyings that are based on operations or activities specific to one of the parties to the contract, if the contract does not have (1) variables based on a market rate, market price, or market index, (2) variables based on the price or performance of a financial asset or financial liability of one of the parties to the contract, (3) contracts or features involving the issuer's own equity, and (4) call options and put options on debt instruments. The ASU is effective for annual periods beginning after December 15, 2026, and interim periods within those annual reporting periods. Early adoption is permitted. The Company is currently evaluating the timing of the adoption and the impact of the new standard on its consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities. This standard establish the accounting for a government grant received by a business entity. In addition, this standard requires a business entity to provide disclosures, including the nature of the government grant received, the accounting policies used to account for the grant, and significant terns and conditions of the grant. The standard is effective for interim and annual reporting periods beginning after December 15, 2028 on a modified prospective approach, a modified retrospective approach, or a retrospective approach. Early adoption is permitted. The Company is currently evaluating the timing of the adoption and the impact of the new standard on its consolidated financial statements and related disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. This standard provides a comprehensive list of interim disclosures that are required by GAAP and includes a disclosure principle that requires entities to disclose events since the end of the last annual reporting period that have a material impact on the entity. The standard is effective for interim reporting periods within annual reporting periods beginning after December 15, 2027 on a prospective or retrospective basis. Early adoption is permitted. The Company is currently evaluating the timing of the adoption and the impact of the new standard on its consolidated financial statements and related disclosures.

**2. Business Combination**

On March 4, 2024, QT Imaging, GigCapital5, and QT Merger Sub, consummated the closing of the transactions contemplated by the Business Combination Agreement, following the approval at an annual stockholder meeting of the stockholders of GigCapital5 held on February 20, 2024 (the "***Stockholder Meeting***").

QT Imaging has been determined to be the accounting acquirer and the Business Combination was accounted for as a reverse recapitalization. The shares and net loss per common share prior to the Merger have been retroactively restated as shares reflecting the exchange ratio established in the Merger (approximately 0.3427 shares of the Company's common

------

stock for each share of QT Imaging common stock). The net liabilities of GigCapital5 have been recognized at carrying value, with no goodwill or other intangible assets recorded.

The following summarizes the elements of the Merger to the consolidated statements of stockholders' equity (deficit) and cash flows, including the transaction funding, sources, and uses of cash:

---

| | |
|:---|:---|
| *(in thousands)* | **Recapitalization** |
| Cash in GigCapital5 Trust Account, net of redemptions | $13953 |

***Merger Related Activities***

On November 15, 2023, GigCapital5, QT Imaging and Yorkville, a Cayman Islands exempt limited partnership managed by Yorkville Advisors Global, LP, entered into the SEPA. Upon the closing of the Merger, the Company has the right, provided there is no balance outstanding under the Yorkville Note or, if there is a balance outstanding under a Yorkville Note, with Yorkville's prior written consent, or upon the occurrence of certain trigger events, to issue and sell to Yorkville, and Yorkville shall purchase from the Company, up to $10.0 million in aggregate gross purchase price (the "***Commitment Amount***") of newly issued shares of the common stock (each such sale, an "***Advance***") by delivering written notice to Yorkville (each, an "***Advance Notice***" and the date on which the Company is deemed to have delivered an Advance Notice, the "Advance Notice Date"). As consideration for a payment of $10.0 million (the "***Pre-Paid Advance***") received on March 4, 2024, the Company issued the Yorkville Note, which was issued with a 6% original issue discount. The Yorkville Note for the Pre-Paid Advance was originally due 15 months from the date of issuance, and interest accrues on the outstanding balance of the Yorkville Note at an annual rate equal to 6%, subject to an increase to 18% upon an event of default. The Yorkville Note is convertible by Yorkville into shares of the Company's common stock. On March 4, 2024, immediately prior to, and substantially concurrently with, the closing of the Business Combination, QT Imaging issued to Yorkville that number of shares of the Company which converted in the aggregate into 333,334 shares of the Company's common stock (the "Company Shares") upon the completion of the Merger. Refer to Note 7 - Long-Term Debt for more information.

In February 2024, GigCapital5 and QT Imaging entered into the Cable Car Note with Cable Car, pursuant to which Cable Car agreed to advance $1.5 million at the closing of the Business Combination, as was evidenced by a promissory note that may be convertible in certain circumstances into shares of the Company's common stock at a conversion price of $6.00 per share (the "Loan"), dated March 4, 2024, by and between QT Imaging and Cable Car. The Loan does not bear interest, and is due and payable 13 months after issuance, unless the time for payment is accelerated as a result of an event of default. On March 4, 2024, as full compensation to Cable Car for the Loan to QT Imaging in lieu of any simple or in-kind interest on the Loan, QT Imaging issued to Cable Car that number of shares of the Company which at the completion of the Business Combination would be converted in accordance with the terms of the Business Combination Agreement into 60,000 shares of the Company's common stock. Refer to Note 7 - Long-Term Debt for more information.

In February 2024, GigCapital5 and QT Imaging (together the "***parties***") entered into a subscription agreement with William Blair & Co., L.L.C. ("***William Blair***") for the purchase of shares of common stock of QT Imaging. Pursuant to the subscription agreement, QT Imaging issued to William Blair in satisfaction of certain fees owed to William Blair for its services to the parties, that number of shares of QT Imaging which at the completion of the Business Combination were converted in accordance with the terms of the Business Combination Agreement into 246,667 shares of the Company's common stock. The issuance of these shares settled $2.4 million of net assumed liabilities from the Business Combination

------

with an additional transaction cost expense of $0.2 million recorded as selling, general and administrative expense within the consolidated statement of operations and comprehensive loss during the year ended December 31, 2024.

In February 2024, the parties agreed to amend one of the non-redemption agreements that were entered into in December 2023 ("***December 2023 Non-Redemption Agreements***"), pursuant to which, and in addition to the Company's common stock issuable Mizuho Securities USA, LLC ("***Mizuho***") under the December 2023 Non-Redemption Agreement, Mizuho received from QT Imaging, in exchange for $0.3 million of services rendered by Mizuho, that number of QT Imaging's common stock that converted in accordance with the terms of the Business Combination Agreement into 33,334 shares of the Company's common stock. The issuance of these shares settled $0.3 million of net assumed liabilities from the Business Combination with an additional transaction expense of $0.1 million recorded as selling, general and administrative expense within the consolidated statement of operations and comprehensive loss during the year ended December 31, 2024.

In February 2024, QT Imaging and GigCapital5 entered into two additional subscription agreements with each of Donnelley Financial Solutions, LLC ("***DFIN***") and IB Capital LLC ("***iBankers***"), dated as of February 23, 2024 and February 22, 2024, respectively (together, the "***Subscription Agreements***"), for the purchase of shares of common stock of QT Imaging. Pursuant to the Subscription Agreements, QT Imaging issued to each of DFIN and iBankers in satisfaction of $0.5 million and $0.6 million of fees owed to DFIN and iBankers, respectively, for their services, that number of shares of QT Imaging which at the completion of the Business Combination were converted in accordance with the terms of the Business Combination Agreement into 66,667 and 80,000 respective shares of the Company's common stock. The issuance of these shares settled $1.1 million of net assumed liabilities from the Business Combination with an additional transaction expense of $0.5 million recorded as selling, general and administrative expense within the consolidated statement of operations and comprehensive loss during the year ended December 31, 2024.

In February 2024, QT Imaging and LionBay Ventures ("***LionBay***") entered into a Settlement and Termination Agreement ("***LionBay Termination Agreement***"). Pursuant to the terms of the LionBay Termination Agreement, QT Imaging terminated its Service Agreement with LionBay dated May 18, 2021 and the First Amendment of the Service Agreement dated September 9, 2021 (collectively as "***Service Agreement***"). In exchange for the termination of the Service Agreement and the termination of options to purchase 5,667 shares of common stock with a strike price of $25.50 per option that were issued as part of the Service Agreement, QT Imaging agreed to issue that number of shares that converted into 3,333 shares of the Company's common stock. The issuance of these shares resulted in an additional transaction expense of $35 thousand recorded as selling, general and administrative expense within the consolidated statement of operations and comprehensive loss during the year ended December 31, 2024.

In February 2024, QT Imaging received $0.5 million in exchange for that number of shares that converted into 66,667 shares of the Company's common stock in accordance with the terms of the subscription agreement and Business Combination Agreement. The issuance of these shares resulted in an additional transaction expense of $0.2 million recorded as selling, general and administrative expense within the consolidated statement of operations and comprehensive loss during the year ended December 31, 2024.

Pursuant to an amendment dated December 13, 2023, between QT Imaging and Exit Strategy Partners, LLC ("***Advisor***"), the Company agreed to pay for Advisor's services in exchange for that number of shares that converted into 83,334 shares of the Company's common stock and a total cash amount of $0.2 million, of which $0.1 million was paid on the closing of the Business Combination on March 4, 2024 and the remaining $0.1 million is due on the first anniversary of the closing of the Business Combination, which is recorded in accrued expenses and other current liabilities within the consolidated balance sheet as of December 31, 2024. The total cash consideration and issuance of shares related to this amendment resulted in a transaction expense of $1.1 million recorded as selling, general and administrative expense within the consolidated statement of operations and comprehensive loss during the year ended December 31, 2024.

On March 4, 2024, as consideration for the December 2023 Non-Redemption with certain GigCapital5 stockholders ("***Non-Redeeming Stockholders***"), QT Imaging issued that number of shares that converted into 142,492 shares of the Company's common stock to the Non-Redeeming Stockholders. The issuance of these shares resulted in a transaction expense of $1.5 million recorded as selling, general and administrative expense within the consolidated statement of operations and comprehensive loss during the year ended December 31, 2024.

On March 4, 2024, the Company issued to subscribers to the Stock Subscription Agreements entered into in November 2023 that number of shares that resulted in such parties as stockholders of QT Imaging receiving, pursuant to the Business Combination Agreement, 50,000 shares of the Company's common stock. The issuance of these shares resulted in a transaction expense of $0.5 million recorded as selling, general and administrative expense within the consolidated statement of operations and comprehensive loss during the year ended December 31, 2024.

***Merger Earnout Consideration Shares***

Pursuant to the Second Amendment to Business Combination Agreement dated September 21, 2023, the Company is obliged to issue a maximum of 3,000,000 shares of Company's common stock (the "***Merger Consideration Earnout Shares***") if certain triggering events and conditions are achieved during 2024, 2025, and 2026.

*2024 Earnout Shares*

Promptly following the date on which Company files its quarterly report on Form 10-Q with respect to its fiscal quarter ended September 30, 2024 with the SEC, an aggregate of 833,333 Merger Consideration Earnout Shares (the "***2024 Earnout Shares***") will be issued to QT Imaging's former stockholders if, and only if, on or prior to such filing date, the Company has obtained a formal Food and Drug Administration ("***FDA***") clearance for breast cancer screening with respect to its breast scanning systems, which remains in full force and effect as of such filing date; provided, that the 2024 Earnout Shares shall increase by 166,667 (to an aggregate of 1,000,000) Merger Consideration Earnout Shares if, in addition, during the fifteen months ended September 30, 2024, the Company either (A) makes at least eight bona fide placements of its breast scanning systems globally or (B) has revenue of at least $4.4 million as set forth in the condensed consolidated financial statements included in the periodic reports filed by the Company with the SEC with respect to such fifteen month period.

The Company recorded a liability of $3.7 million related to the Merger Earnout Consideration Shares within the consolidated balance sheet on the date of initial recognition (March 4, 2024). As of December 31, 2025 and 2024, the liability related to the Merger Earnout Consideration Shares was $2.2 million and $0.4 million, respectively. Refer to Note 3 - Fair Value Measurements for more information.

**3. Fair Value Measurements**

The fair value of the Company's financial assets and liabilities reflects management's estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3: Unobservable inputs which are supported by little or no market activity and which are significant to the fair value of the assets or liabilities.

The following table presents information about the Company's assets and liabilities that are measured at fair value on a recurring basis as of December 31, 2025 and 2024, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

***Warrant Liability***

The Company has determined that the warrants that were a constituent part of (i) the private placement units issued in a private placement sale by GigCapital5 prior to the Merger and (ii) the private placement units issued upon conversion of working capital notes issued by GigCapital5 (the "***Working Capital Note Warrants***") prior to the Merger, which conversion occurred concurrent with the Merger ("***Private Warrants***"), are subject to treatment as a liability, as the transfer of the warrants to anyone other than the purchasers or their permitted transferees would result in these warrants having substantially the same terms as the warrants included in the public units that were issued by GigCapital5 prior to the Merger ("***Public Warrants***"). The Company determined that the fair value of each Private Warrant approximates the fair value of a Public Warrant. Accordingly, the Private Warrants are valued upon observable data and have been classified as Level 2 financial instruments. As of December 31, 2025 and 2024, a total of 889,364 Private Warrants to purchase 296,445

shares of common stock were outstanding at an approximate fair value of $0.116 and $0.025 per warrant, respectively. Refer to Note 10 - Stockholders' Equity (Deficit) for more information.

On February 26, 2025, the Company entered into the Credit Agreement that provides the Lynrock Lake Term Loan. In connection with the Lynrock Lake Term Loan, the Company issued to Lynrock Lake, pursuant to the terms of a Warrant to Purchase Common Stock (the "***Lynrock Lake Warrant***"), a warrant to purchase 20,333,623 shares of common stock at an exercise price of $1.20 per share. The Lynrock Lake Warrant is exercisable until February 26, 2035. Lynrock Lake may cashless exercise the Lynrock Lake Warrant. The Lynrock Lake Warrant is also subject to anti-dilution adjustments to the exercise price and the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant in the event that the Company issues shares of common stock (or derivative securities) at a price that is either less than the $1.20 exercise price or the fair market value of a share of common stock from the immediately prior trading day. On June 11, 2025, the Lynrock Lake Warrant was amended to update the provisions that would trigger cash settlement such that, when such events occur, the holders of the warrants receive the same form of consideration as the underlying stockholders. Consequently, upon modification, the warrants were revalued and then reclassified to additional paid-in capital on the consolidated balance sheets. The Company determined the fair value of the Lynrock Lake Warrant using the Black-Scholes pricing model. Refer to Note 7 - Long-Term Debt for more information.

On February 26, 2025, the Company issued to Yorkville a warrant to purchase 5,000,071 shares of common stock at an exercise price of $1.20 per share pursuant to the Yorkville Warrant to fully settle and discharge the Company's obligations under the Yorkville Note and extinguish the Yorkville Note as having been fully performed. The Yorkville Warrant is exercisable until February 26, 2030. Yorkville may cashless exercise the Yorkville Warrant. The Yorkville Warrant is also subject to adjustments in the event that the Company's common stock undergoes a split, reverse-split or similar event. Furthermore, the Yorkville Warrant has provided the holder with piggyback registration rights. On June 11, 2025, the Yorkville Warrant was amended to update the provisions that would trigger cash settlement such that, when such events occur, the holders of the warrants receive the same form of consideration as the underlying stockholders. According to Accounting Standards Codification 815-40, Derivatives and Hedging: Contracts in an Entities Own Equity, equity classification is permitted for an instrument that requires net-cash settlement if the holders of the contract's underlying shares receive the same form of consideration in transactions outside the company's control. Consequently, upon modification, the warrants were revalued and then reclassified to additional paid-in capital on the consolidated balance sheets. The Company determined the fair value of the Yorkville Warrant using the Black-Scholes Model. Refer to Note 7 - Long-Term Debt for more information.

***Earnout Liability***

The fair value of the Merger Consideration Earnout shares was calculated using a Monte Carlo simulation. The simulation used as significant inputs the Company's management's current assessment of placements of breast scanning systems in 2024 and 2025, likely expected values for revenues from 2024 through 2026, probabilities for regulatory approvals including FDA clearances, and probabilities of other triggering events related to the open angle scanner. The probabilities of the non-revenue triggers generally range from 0 to 25 percent. The revenue forecast for the respective measurement periods are generally in line with the revenue triggers as defined in the Business Combination Agreement, as amended. Additional significant inputs into the simulation include the volatility of Company's equity, assets, and revenue that was derived in a manner as would be common for such simulation, and published industry operating profitability metrics. A weighted average cost of capital ("***WACC***") was estimated based on a venture capital rates of return on debt and equity. This WACC was used as the discount rate applicable to revenue, after applying a delivering factor to convert it from being applicable to earnings before interest and tax ("***EBIT***") to being applicable to revenue. This EBIT to revenue delivering factor was estimated using published industry operating profit and cost metrics.

The Monte Carlo simulation developed a distribution of projected revenues for 2024 through 2026 using a Geometric Brownian Motion framework based on a standard normal distribution of returns. The simulation also developed a distribution of potential daily common stock prices for 2026 using a Geometric Brownian Motion framework. The resulting fair value is based on the average of the number of shares that will be paid out for each triggering event over a statistically significant number of simulations.

The Gulf Medical Distribution Agreement, which was signed on August 21, 2025, contained MOQs, which increased the likely expected value for revenue in 2026, resulting in a change in fair value of $1.8 million for the year ended December 31, 2025.

Significant assumptions used in the valuation of the fair value of the earnout liability as of December 31, 2025 and 2024 were as follows:

***Derivative Liability***

In March 2024, the Company recorded a derivative liability related to the Pre-Paid Advance issued on March 4, 2024 pursuant to the SEPA, dated November 15, 2023, between QT Imaging and Yorkville. The Pre-Paid Advance contained the following derivative features ("***Derivatives***") as defined in the SEPA that were recognized at fair value:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Monthly Payment Premium: if, any time after the Issuance Date, and from time to time thereafter, a Trigger Event occurs, then the Company shall make monthly payments of Triggered Principal Amount, Payment Premium and accrued and unpaid interest.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Monthly Payment Discount: if, any time after the Issuance Date, and from time to time thereafter, a Trigger Event occurs, then the Company shall make monthly payments of Triggered Principal Amount minus the lesser of (x) $1.5 million and (y) such amount of fifty percent (50%) of the Investor's net sales proceeds of the common stock issued to Yorkville upon the Merger (the "Company Shares") or fifty percent (50%) of the value of the Company Shares on such date the cash payment is due.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Variable Price Conversion Right: subject to certain limitations, at any time or times on or after the Issuance Date, the Yorkville shall be entitled to convert any portion of the outstanding and unpaid Conversion Amount into fully paid and nonassessable common stock in accordance with Section (3)(b), at the Conversion Price of 95% of the lowest VWAP of the Company's common stock during the 5 consecutive Trading Days immediately preceding the Conversion Date or the date the Holder submits an Investor Notice pursuant to and as defined in the SEPA, as applicable, or other date of determination, but not lower than the Floor Price (as such term is defined in the York Note).

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Failure to Timely Convert: if within three (3) Trading Days after the Company's receipt of an email copy of a Conversion Notice the Company shall fail to issue and deliver a certificate to the Yorkville or credit Yorkville's balance account with DTC for the number of shares of common stock to which the Holder is entitled upon such Yorkville's conversion of any Conversion Amount (a "Conversion Failure"), and if on or after such Trading Day the Yorkville purchases (in an open market transaction or otherwise) common stock to deliver in satisfaction of a sale by the Yorkville of common stock issuable upon such conversion that the Yorkville anticipated receiving from the Company (a "***Buy-In***"), then the Company shall, within three (3) Business Days after the Yorkville's request and in the Yorkville's discretion, either (i) pay cash to Yorkville in an amount equal to Yorkville's total purchase price (including brokerage commissions and other out of pocket expenses, if any) for the common stock so purchased (the "Buy-In Price"), or (ii) promptly honor its obligation to deliver to the Yorkville a certificate or certificates representing such common stock and pay cash to the Yorkville in an amount equal to the excess (if any) of the Buy-In Price over the product of (A) such number of shares of common stock, times (B) the closing price on the conversion date.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Corporate Events: in addition to and not in substitution for any other rights hereunder, prior to the consummation of any Fundamental Transaction pursuant to which holders of common stock are entitled to receive securities or other assets with respect to or in exchange for shares of common stock (a "***Corporate Event***"), the Company shall make appropriate provision to ensure that the Holder will thereafter have the right to receive upon a conversion of this Yorkville Note, at the Holder's option, (i) in addition to the common stock receivable upon such conversion,

------

such securities or other assets to which the Holder would have been entitled with respect to such common stock had such common stock been held by the Holder upon the consummation of such Corporate Event (without taking into account any limitations or restrictions on the convertibility of the Yorkville Note) or (ii) in lieu of the common stock otherwise receivable upon such conversion, such securities or other assets received by the holders of common stock in connection with the consummation of such Corporate Event in such amounts as the Holder would have been entitled to receive had the Yorkville Note initially been issued with conversion rights for the form of such consideration (as opposed to common stock) at a conversion rate for such consideration commensurate with the Conversion Price. Provision made pursuant to the preceding sentence shall be in a form and substance satisfactory to the Required Holders.

The initial fair value of the above Derivatives was calculated using a Monte Carlo simulation. The simulation used significant inputs, including volatility of Company's equity that was derived based on a comparable peer group of publicly traded companies and the Company's stock price on the valuation date.

The total value of the derivatives reflected the combined value of the monthly payment premium, reduction to that premium by the payment discount, and the value of the conversion right. The values of the failure to timely convert and corporate event features were deemed to be de minimis.

The Company and Yorkville entered into that certain Termination Agreement, dated February 26, 2025 (the "***Termination Agreement***"), pursuant to which the parties acknowledged the termination of the SEPA and the Yorkville Note, effective as of February 26, 2025. As such, on the effective date of the Termination Agreement, the derivative liability was deemed to be extinguished. The Company recorded the change in fair value of the derivative liability within the consolidated statements of operations and comprehensive loss as of the date immediately prior to the effective date of the Termination Agreement. Refer to Note 7 - Long-Term Debt for more information.

***Yorkville Pre-Paid Advance***

On March 4, 2024, the Company received a Pre-Paid Advance of $10.0 million from Yorkville and issued Yorkville the Yorkville Note in the amount of $10.0 million for such Pre-Paid Advance that was originally due 15 months from the date of issuance, and interest shall accrue on the outstanding balance of the Yorkville Note at an annual rate equal to 6%, subject to an increase to 18% upon an event of default as described in the Yorkville Note. The Yorkville Note is convertible by Yorkville into shares of the Company's common stock. As consideration for the Pre-Paid Advance, immediately prior to, and substantially concurrently with, the closing of the Business Combination, QT Imaging issued to Yorkville that number of shares of QT Imaging which converted in the aggregate into 333,334 shares of the Company's common stock upon the completion of the Business Combination. The proceeds of $10.0 million were recorded between the promissory note and common stock less debt origination costs of $1.0 million, consisting of a $0.4 million commitment fee for the SEPA and an original issue discount of 6% for the Yorkville Note, on a relative fair value basis.

As noted in Note 3 - Fair Value Measurements, the Pre-Paid Advance contained Derivatives that were bifurcated and recorded a separate instrument. The initial value of the Derivatives of $5.1 million was recorded as a debt discount against the Pre-Paid Advance.

Under the terms of the original Yorkville Note, a "***Trigger Event***" shall occur if the daily VWAP is less than the Floor Price for five trading days during a period of seven consecutive trading days (a "***Floor Price Trigger***" and the last such day of such occurrence, a "***Trigger Date***"). If, at any time six months after the issuance of the Yorkville Note, a Trigger Event occurs, then the Company will be obligated to make monthly payments in an amount equal to the sum of (i) $1.5 million of principal in the aggregate among all promissory notes issued to Yorkville (or the outstanding principal if less than such amount) (the "***Triggered Principal Amount***"), plus (ii) a payment premium of 5% in respect of such Triggered Principal Amount, and (iii) accrued and unpaid interest hereunder as of each payment date beginning on the 5th trading day

------

after the Trigger Date and continuing on the same day of each successive calendar month to Yorkville pursuant to the terms of the Yorkville Note. However, in the event that the Company shall be required to make such cash payments to Yorkville under the Yorkville Note as a result of the occurrence of a Trigger Event, the Company shall be entitled upon written notice to Yorkville, to direct that Yorkville (i) if Yorkville has sold the Company Shares that it received upon the completion of the Merger to apply, in accordance with the terms of the Yorkville Note, up to 50% of Yorkville's net sale proceeds of the Company Shares to satisfy, in part or in whole, the Triggered Principal Amount of such cash payments due to Yorkville or (ii) or if Yorkville has not sold the Company Shares, to apply up to 50% of the value of the Company Shares on such date the cash payment is due based on the VWAP as quoted by Bloomberg LP of the Company Shares as an offset of the Triggered Principal Amount of the cash payments due to Yorkville. The obligation of the Company to make monthly prepayments due to the occurrence of a Floor Price Trigger shall cease (with respect to any payment that has not yet come due) if any time after the Trigger Date (a) the Company reduces the Floor Price to an amount that is at least 50% of the daily VWAP of the common stock or (b) the daily VWAP is greater than 110% of the Floor Price for a period of five consecutive trading days, unless a subsequent Trigger Event occurs. Furthermore, within one trading day of a Floor Price Trigger that remains after application of all amounts related to the Company Shares as described above, the Company shall reduce the Floor Price to an amount that is at least 50% of the daily VWAP of the common stock, and provide Yorkville written confirmation of such reduction of the Floor Price or be obligated to make the above monthly cash payments.

Following the effectiveness of the registration statement on Form S-1 that the Company filed to register the shares to be issued pursuant to the SEPA, the Floor Price for Yorkville was $2.6304 per share. For the first five trading days commencing after six months after the issuance of the Yorkville Note, which ended on September 11, 2024, the daily VWAP of the common stock was less than the Floor Price, and as a result, September 11, 2024 constitutes a Trigger Date, and on that Trigger Date, a Trigger Event occurred due to a Floor Price Trigger. Accordingly, on September 13, 2024, the Company made the initial payment due to Yorkville as a result of the Trigger Event that occurred on September 11, 2024 in an amount totaling $1.5 million, the calculation of which reflects a reduction to the Triggered Principal Amount by 50% of the net sale proceeds of the Company Shares by Yorkville following the closing of the Business Combination. The total payment of $1.5 million was comprised of $1.1 million of principal, $0.3 million of accrued interest, and $0.1 million of 5% early payment premium. The Company recognized the 5% early payment premium as interest expense within the consolidated statements of operations and comprehensive loss during the year ended December 31, 2024.

On September 26, 2024, the Company and Yorkville entered into an Omnibus Amendment (the "***Omnibus Amendment***"), pursuant to which the Company and Yorkville agreed to amend certain terms of the Yorkville Note to reduce the Company's obligations resulting from the occurrence of the Trigger Event. Pursuant to the Omnibus Amendment, the maturity date of the Yorkville Note was extended approximately six months from June 4, 2025 to December 15, 2025. Further, the Omnibus Amendment acknowledges the Company's obligation to make monthly payments to Yorkville in the amount of the Trigger Principal Amount due to the occurrence of the Trigger Event and revised the Yorkville Note to provide that no further monthly payments will be owed during the period beginning on the date of the Omnibus Amendment and ending on January 15, 2025. In exchange for this relief, beginning on January 15, 2025, and continuing on the same day of each successive calendar month until and including November 15, 2025, whether or not a Trigger Event has occurred and is continuing as of such dates, the Company will make monthly payments in an amount equal to $0.5 million plus the payment premium of 5% plus accrued and unpaid interest under the Yorkville Note as of each such payment date. Such monthly payments will not be reduced or offset by any amount, including, but not limited to, any net sales proceeds of the Company Shares or any value of the Company Shares based on the VWAP as quoted by Bloomberg, LP. The Omnibus Amendment also provided that 100% of the proceeds of the sale of the remaining 133,334 Company Shares held at the time of entry into the Omnibus Amendment by Yorkville shall be retained by Yorkville and shall not be used to offset or reduce any amounts owed under the Yorkville Note, or to otherwise benefit the Company in any way. Pursuant to the Omnibus Amendment, the delisting of the Company's common stock from trading on the Nasdaq Stock Market will not constitute an Event of Default, provided that (i) the Company uses its best efforts to have its common stock relisted on the Nasdaq Stock Market as soon as possible and (ii) the Company's common stock is listed on the OTC Markets' OTCQX market tier within 30 days in the event that a delisting from the Nasdaq Stock Market occurs. The Omnibus Amendment was accounted for as a troubled debt restructuring, resulting in a prospective adjustment to the effective interest rate.

On October 31, 2024, the Company and Yorkville executed the Second Omnibus Amendment to the Yorkville Note (the "***Second Amendment***"), pursuant to which the maturity date of the Yorkville Note was extended from December 15, 2025 to March 31, 2026. Further, the Second Amendment acknowledged the Company's obligation to make monthly payments

------

to Yorkville in the amount of the Trigger Principal Amount due to the occurrence of the Trigger Event and no further monthly payments will be owed during the period beginning on the date of the Second Amendment and ending on February 15, 2025. In exchange for this relief, beginning on February 15, 2025, and continuing on the same day of each successive calendar month until and including February 15, 2026, whether or not a Trigger Event has occurred and is continuing as of such dates, the Company agreed to make monthly payments in an amount equal to $0.5 million plus the payment premium plus accrued and unpaid interest as of each such payment date. Such monthly payments under the Second Amendment were not to be reduced or offset by any amount, including, but not limited to, any net sales proceeds of the Company Shares or any value of the Company Shares based on the VWAP as quoted by Bloomberg, LP. Further, pursuant to the terms of the Second Amendment, the Company elected to reduce the Floor Price to $1.50 per share, effective as of the date of the Second Amendment. In addition, the Second Amendment provided that to the extent that Yorkville converts any portion of the Investor Note into shares of the common stock between the date of the Second Amendment and January 15, 2025, the first $0.5 million of such conversions of the Yorkville Note shall reduce the principal balance of the Yorkville Note. For the avoidance of doubt and without implication that the opposite would otherwise be true, all other conversions of the Yorkville Note pursuant to the Second Amendment were to be applied as provided for in and consistent with the terms of the Yorkville Note. The Second Amendment also provided that in the event that the common stock is delisted from trading on the Nasdaq Stock Market, Yorkville consents to the occurrence of such delisting from the Nasdaq Stock Market, if it is to happen, and that it will not constitute an Event of Default as defined per the Omnibus Amendment, provided that (i) the Company uses its best efforts to have the common stock relisted on the Nasdaq Stock Market as soon as possible and (ii) the common stock is listed on the OTC Markets' OTCQX or OTCQB market tiers within 30 days in the event that a delisting from the Nasdaq Stock Market occurs. The Second Amendment was accounted for as a debt modification, resulting in a prospective adjustment to the effective interest rate.

On November 4, 2024, Yorkville converted $0.3 million of outstanding principal into 128,020 shares of common stock with an applicable conversion price of $1.9887 per share. On December 6, 2024, Yorkville converted an additional $0.3 million of outstanding principal under the Yorkville Note into 173,059 shares of common stock with an applicable conversion price of $1.50 per share.

On January 9, 2025, the Company and Yorkville entered into the Third Omnibus Amendment to the Yorkville Note, (the "***Third Amendment***"), pursuant to which, the Company and Yorkville agreed that for $1.5 million of the then current outstanding balance due under the Yorkville Note (principal and unpaid accrued interest), the fixed price for conversion shall be modified to $1.752 per share, and for the remainder of the balance, the fixed price shall not be changed but shall remain $13.84185 per share as provided for in the Yorkville Note when the Company issued it on March 4, 2024. Further, the Third Amendment removed the Company's obligation to make monthly payments to Yorkville, previously owing due to the occurrence of the Trigger Event, through the maturity date of the Yorkville Note of March 31, 2026. In exchange for this relief, the aggregate purchase price owed to the Company from the first Advance that occurs pursuant to the terms of the SEPA (the "***Advance Proceeds***") shall be paid by Yorkville offsetting the amount of the Advance Proceeds against an equal amount outstanding under the Yorkville Note (first towards accrued and unpaid interest, and then towards outstanding principal and the corresponding payment premium in respect of such principal amount, if applicable), and that for any subsequent Advances pursuant to the terms of the SEPA, Yorkville shall pay half of such Advance Proceeds directly to the Company and the other half of such Advance Proceeds shall be paid by Yorkville offsetting the amount of the Advance Proceeds against an equal amount outstanding under the Yorkville Note (first towards accrued and unpaid interest, and then towards outstanding principal and the corresponding payment premium in respect of such principal amount, if applicable). On January 9, 2025, the Company delivered its first Advance Notice as defined under the SEPA for the sale of 295,000 shares of common stock. This resulted in the reduction of an additional $0.2 million in principal of the Yorkville Note.

On February 26, 2025, the Company used a portion of the proceeds of the Lynrock Lake Term Loan to pay Yorkville an amount equal to $3.0 million in cash and issued to Yorkville a warrant to purchase 5,000,071 shares of its common stock at an exercise price of 1.20 per share pursuant to the Yorkville Warrant to fully settle and discharge the Company's obligations under the Yorkville Note and extinguish the Yorkville Note as having been fully performed. The Yorkville Warrant is exercisable until February 26, 2030. The Company and Yorkville also entered into that certain Termination Agreement, dated February 26, 2025, pursuant to which the parties acknowledged the termination of the SEPA effective February 26, 2025. The fair value of the Yorkville Warrant at issuance amounted to $3.0 million. As a result of the extinguishment of the Yorkville Note, the Company recorded an expense of $1.9 million in other expense, net within the consolidated statements of operations and comprehensive loss for the year ended December 31, 2025. As of December 31,

------

2024, the outstanding amount of the Yorkville Note was $3.5 million, net of the unamortized debt discount of $4.8 million and accrued interest of $0.2 million. As of December 31, 2025, there was no amount outstanding for the Yorkville Note. Interest expense, including amortization of debt issuance costs, for the years ended December 31, 2025 and 2024 was $0.5 million and $3.7 million, respectively.

***Cable Car Note***

In February 2024, GigCapital5 and QT Imaging entered into the Cable Car Note with Cable Car, pursuant to which Cable Car agreed to advance $1.5 million at the closing of the Business Combination, as was evidenced by the Loan dated March 4, 2024, by and between QT Imaging and Cable Car. The Loan does not bear interest, and is due and payable 13 months after issuance, unless the time for payment is accelerated as a result of an event of default. As full compensation to Cable Car for the Loan to QT Imaging in lieu of any simple or in-kind interest on the Loan, QT Imaging issued to Cable Car that number of shares of QT Imaging which at the completion of the Business Combination would be converted in accordance with the terms of the Business Combination Agreement into 60,000 shares of the Company's common stock. The proceeds of $1.5 million were recorded between the promissory note and common stock less debt origination costs of $41 thousand, consisting of legal fees, on a relative fair value basis.

On January 9, 2025, the Company and Cable Car entered into an Omnibus Amendment (the "***Cable Car Amendment***") to amend certain terms of the Cable Car Note, including a reduction of the conversion price for the Cable Car Note to $1.752 per share. Further, the Cable Car Amendment provides that the maturity date for the Cable Car Note shall be extended to March 31, 2026, in exchange for an extension fee (the "***Extension Fee***") of $0.1 million to Cable Car, with such fee being added to the amount due and payable on such maturity date, unless the Cable Car Note is earlier converted pursuant to its terms, in which event the Extension Fee shall also be converted. No interest shall accrue or be due on the Extension Fee. Pursuant to the Cable Car Amendment, interest shall accrue on the outstanding principal balance of the Cable Car Note at an annual rate equal to 6%, with interest being calculated based on a 365-day year and the actual number of days elapsed, to the extent permitted by applicable law. Interest shall be due and payable on the maturity date for the Cable Car Note, unless the Cable Car Note is earlier converted pursuant to its terms, in which event such accrued and unpaid interest shall also be converted. In addition, in connection with any sale, assignment, transfer, or other disposition (a "***Cable Car Sale***") of any shares into which the Cable Car Note is converted pursuant to its terms, the Cable Car Amendment provides that to the extent such Cable Car Sale is made pursuant to Rule 144, provided that Rule 144 is available as an exemption from the registration requirements for such Cable Car Sale, if requested by Cable Car and upon delivery by Cable Car of such customary representations and other documentation reasonably acceptable to the Company in connection with transactions relying upon Rule 144, the Company shall use commercially reasonable efforts to cause its transfer agent to remove any restrictive legends related to the book entry account holding such shares sold or disposed of by Cable Car without restrictive legends within two business days of such request. The Company recorded the Extension Fee of $0.1 million in other expense, net within the consolidated statements of operations and comprehensive loss for the year ended December 31, 2025.

On February 26, 2025, the Company used a portion of the proceeds of the Lynrock Lake Term Loan to pay Cable Car an amount equal to the full principal, interest and fees amount of approximately $1.6 million in cash to fully settle and discharge the Company's obligations under the Cable Car Note and extinguish the Cable Car Note as having been fully performed. As a result of the extinguishment of the Cable Car Note, the Company recorded an expense of $0.1 million in other expense, net within the consolidated statements of operations and comprehensive loss for the year ended December 31, 2025.

As of December 31, 2024, the outstanding amount of the Cable Car Note was $1.4 million, net of unamortized issuance costs of $0.1 million. As of December 31, 2025, there was no amount outstanding for the Cable Care Loan. Interest expense, including amortization of debt issuance costs, for the years ended December 31, 2025 and 2024 was $36 thousand and $0.4 million, respectively.

***Lynrock Lake Term Loan***

On February 26, 2025, the Company entered into the Lynrock Lake Credit Agreement that provides the Lynrock Lake Term Loan with Lynrock Lake. The Lynrock Lake Credit Agreement is secured by a first priority lien on substantially all assets of the Company and provides for a term loan in the aggregate principal amount of $10.1 million at an interest rate of 10.0% per annum, compounded quarterly. The maturity date of the Lynrock Lake Credit Agreement is March 31, 2027.

------

The Lynrock Lake Term Loan shall be repaid on the maturity date in an amount equal to the aggregate principal amount outstanding, together with all accrued and unpaid interest and any outstanding and payable fees.

Subject to the payment of the Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement), the Company may at any time prior to the maturity date optionally prepay the term loan, in full or in part, upon irrevocable written notice of three business days prior to the proposed prepayment; provided that if such prepayment is to be funded with the proceeds of a refinancing or disposition, such notice of prepayment may be revoked if the financing or disposition is not consummated; provided further, that any such prepayment made in connection with, or in anticipation of, a Change of Control (as defined in the Lynrock Lake Credit Agreement) will also be subject to a prepayment premium equal to 20% of the amount of principal being prepaid (the "***Prepayment Premium***"). Partial prepayments of the term loan shall be in an aggregate principal amount of $0.3 million or a whole multiple thereof.

Subject to the payment of the Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement), at the option of Lynrock Lake, the Company will make mandatory repayments of the term loan upon the following occurrences:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• &nbsp;&nbsp;&nbsp;&nbsp;If on any date the Company or any of its subsidiaries will receive any cash proceeds from any Extraordinary Receipt (as defined in the Lynrock Lake Credit Agreement) in an amount equal to or exceeding $0.3 million in the aggregate, the Company shall prepay the term loan within five business days of receipt of such cash proceeds, in an amount equal to 100% of the cash proceeds of such Extraordinary Receipt (as defined in the Lynrock Lake Credit Agreement);

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•&nbsp;&nbsp;&nbsp;&nbsp; If any indebtedness will be incurred by the Company or any subsidiary thereof (excluding any indebtedness that the Lynrock Lake Credit Agreement permits the Company to incur), an amount equal to 100% of the net cash proceeds thereof shall be applied on the date of incurrence or receipt toward the prepayment of the term loan;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• &nbsp;&nbsp;&nbsp;&nbsp;If on any date the Company or any of its subsidiaries will receive net cash proceeds in an amount equal to or exceeding (i) $0.3 million in any single transaction or series of related transactions or (ii) $0.3 million in the aggregate for all transactions during the term of the Lynrock Lake Credit Agreement from any Asset Sale (as defined in the Lynrock Lake Credit Agreement) or Recovery Event (as defined in the Lynrock Lake Credit Agreement) then the Company or such subsidiary shall prepay the term loan, on or prior to the date which is five business days after the date of the realization or receipt by the Company or subsidiary in an amount equal to 100% percent of such proceeds; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• &nbsp;&nbsp;&nbsp;&nbsp;Subject to the payment of the Prepayment Premium in addition to the Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement), in the event that a Change of Control (as defined in the Lynrock Lake Credit Agreement) will occur, the Company shall prepay all of the outstanding term loan, on or prior to the date which is two business days after the date of such Change of Control (as defined in the Lynrock Lake Credit Agreement).

There are no requirements to make any prepayment in the event that the Company sells any of its capital stock. In addition, at the option of Lynrock Lake, the Company shall also make mandatory repayments of the term loan on a monthly basis, no later than five business days after the end of each month (provided that such date for payment is prior to the maturity date), if the Company or its subsidiaries receive payment of accounts receivable on or after January 1, 2026, in an amount equal to 15% of the aggregate amount of payments of accounts receivable actually received during such prior month, net of any cost of collection incurred not in the ordinary course of business. No Make-Whole Amount (as defined in the Lynrock Lake Credit Agreement) or Prepayment Premium is due or payable on any such mandatory prepayment as a result of receipt of accounts receivable on or after January 1, 2026. As of December 31, 2025, Lynrock Lake has not elected the repayment option in the amount equal to 15% percent of the aggregate amount of payments of accounts receivable actually received on or after January 1, 2026.

Furthermore, in connection with the Lynrock Lake Term Loan, the Company issued to Lynrock Lake the Lynrock Lake Warrant, a warrant to purchase 20,333,623 shares of its common stock at an exercise price of $1.20 per share. The Lynrock Lake Warrant is exercisable until February 26, 2035. Lynrock Lake may cashless exercise the Lynrock Lake Warrant. The Lynrock Lake Warrant is also subject to anti-dilution adjustments to the exercise price and the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant in the event that the Company issues shares of common stock (or

------

derivative securities) at a price that is either less than the $1.20 exercise price or the fair market value of a share of common stock from the immediately prior trading day. The fair value of the Lynrock Warrant at issuance amounted to $16.5 million.

Upon issuance of the Lynrock Lake Term Loan, the Company recorded a loss of $6.6 million, including debt issuance costs of $0.2 million, in other expense, net within the consolidated statements of operations and comprehensive loss for the year ended December 31, 2025.

On August 26, 2025, the Company and Lynrock Lake entered into the Lynrock Lake Amended Credit Agreement to add Tranche B in the amount of $5.0 million to the loan and increase the aggregate principal amount of the Lynrock Lake Term Loan to $15.1 million. The proceeds of Tranche B were used to repurchase the Yorkville Warrant. Tranche B is subject to the Tranche B Premium equal to 6% multiplied by the sum of (a) the principal of Tranche B being repaid plus (b) all related accrued and unpaid interest. Subject to the payment of the Make-Whole Amount, if the Company receives Net Cash Proceeds (as defined in the Lynrock Lake Credit Agreement) from any sale or issuance of the Company's common stock, then the Company shall, at the option of Lynrock Lake, prepay, or cause to be prepaid, Tranche B on or prior to the date which is thirty days after the date of the receipt by the Company of such Net Cash Proceeds in an amount equal to the lesser of (i) 100% of such Net Cash Proceeds or (ii) the principal amount of Tranche B on such date of prepayment, together with all accrued and unpaid interest thereon and any outstanding fees or premium, if any, payable in accordance with the Lynrock Lake Term Loan. Additionally, in connection with any mandatory prepayment of Tranche B on or prior to December 31, 2025, such mandatory prepayment will be subject to the payment of the Tranche B Premium instead of the Make-Whole Amount.

On October 6, 2025, the Company repaid the $5.0 million under Tranche B of the Lynrock Lake Term Loan, plus accrued interest and the Tranche B Premium, with a portion of the proceeds from the October 2025 Private Placement. Refer to Note 10 - Stockholders' Equity (Deficit) for more information.

As of December 31, 2025, the outstanding amount of the Lynrock Lake Term Loan was $0.7 million, net of the unamortized debt discount of $9.4 million, and accrued interest of $0.9 million. Interest expense, including amortization of debt issuance costs, for the year ended December 31, 2025 was $1.6 million.

***Preferred Stock***

The Company is authorized to issue 10,000,000 shares of preferred stock, with a par value of $0.0001, with such designations, voting and other rights and preferences as may be determined from time to time by the Board of Directors. As of December 31, 2025 and 2024, there were no shares of preferred stock issued and outstanding. The Board of Directors has the authority to issue shares of preferred stock from time to time on terms it may determine, to divide shares of preferred stock into one or more series and to fix the designations, preferences, privileges, and restrictions of preferred stock, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preference, sinking fund terms, and the number of shares constituting any series or the designation of any series to the fullest extent permitted by the Delaware General Corporation Law. The issuance of preferred stock could have the effect of decreasing the trading price of common stock, restricting dividends on the capital stock of the Company, diluting the voting power of the common stock, impairing the liquidation rights of the capital stock of the Company, or delaying or preventing a change in control of the Company.

***Warrants (Public Warrants, Private Warrants, Working Capital Note Warrants, PIPE Warrants, Lynrock Lake Warrant, and Yorkville Warrant)***

The Public Warrants, Private Warrants, and Working Capital Note Warrants (collectively, the "***PubCo Warrants***") were originally issued with an exercise price of $34.50 per share, and pursuant to the terms of the warrant agreement governing such warrants (the "***Warrant Agreement"***), the exercise price and number of warrant shares issuable on exercise of the warrants may be adjusted in certain circumstances including in the event of a stock dividend, extraordinary dividend or recapitalization, reorganization, merger or consolidation of the Company. In addition, if (x) the Company issues additional shares of common stock or equity-linked securities for capital raising purposes in connection with the closing of its initial Business Combination at an issue price or effective issue price of less than $27.60 per share of common stock (with such issue price or effective issue price to be determined in good faith by the Company's Board of Directors, and in the case of any such issuance to the Company's Founder or its affiliates, without taking into account any Founder Shares held by it prior to such issuance), (y) the aggregate gross proceeds from such issuances represent more than 65% of the total equity proceeds, and interest thereon, available for the funding of the Company's initial Business Combination on the date of the consummation of its initial Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Company's common stock during the 20 trading-day period starting on the trading day prior to the day on which the Company consummates its initial Business Combination (such price, the "***Market Value***") is below $27.60 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the greater of (i) the Market Value or (ii) the price at which the Company issues the additional shares of common stock or equity-linked securities.

Each warrant became exercisable 30 days after the completion of the Merger and expire five years after the completion of the Merger. If the Company is unable to deliver registered shares of common stock to the holder upon exercise of the warrants during the exercise period, there will be no net cash settlement of these warrants and the warrants will expire worthless, unless they may be exercised on a cashless basis in the circumstances described in the Warrant Agreement. Once

the warrants become exercisable, the Company may redeem the outstanding warrants in whole and not in part at a price of $0.03 per warrant upon a minimum of 30 days' prior written notice of redemption, only in the event that the last sale price of the Company's shares of common stock equals or exceeds $54.00 per share for any 20 trading days within the 30-trading day period ending on the third trading day before the Company sends the notice of redemption to the warrant holders.

Under the terms of the Warrant Agreement, the Company agreed to use its best efforts to file a new registration statement under the Securities Act of 1933, as amended, following the completion of the Merger, for the registration of the shares of common stock issuable upon exercise of the warrants included in the public units issued in the Company's initial public offering, the private placement units undertaken by the Company concurrently with its initial public offering and the private placement units that were issued upon conversion of working capital notes issued by the Company prior to the Merger, which conversion occurred concurrent with the Merger. The new registration statement was filed on April 1, 2024, and was declared effective by the SEC on May 22, 2024.

On May 13, 2024, the exercise price of PubCo Warrants was reduced from $34.50 to $6.90 per warrant and the price per share related to the redemption events described above decreased from $54.00 per share to $10.80 per share in accordance with the terms of the Warrant Agreement as discussed above. As of May 13, 2024, the PubCo Warrants were comprised of 7,666,767 Public Warrants, 264,990 Private Placement Warrants, and 31,455 Working Capital Note Warrants, which were issued under the same Warrant Agreement described above. The modification in exercise price related to the Public Warrants, which are equity classified, was accounted as a deemed dividend, which resulted in an adjustment of $5.2 million to accumulated deficit during the year ended December 31, 2024. The effect of the modification in exercise price related to the Private Placement Warrants and Working Capital Note Warrants, which are liability classified, was recorded in other expense, net within the consolidated statements of operations and comprehensive loss and amounted to $0.2 million during the year ended December 31, 2024. During the year ended December 31, 2025, Public Warrants to purchase 80,405 shares of common stock were exercised for aggregate proceeds of $0.6 million. As of December 31, 2025, there were 7,882,807 PubCo Warrants outstanding with an exercise price of $6.90 per warrant and expiring on March 4, 2029.

Each of the warrants sold in the November 2024 Private Placement (the "***November 2024 PIPE Warrants***") is exercisable for one third of a share of common stock at an exercise price of $2.016 per share, and is exercisable beginning on May 22, 2025 and ending on May 22, 2030. At the closing of the Private Placement, the Company issued November 2024 PIPE Warrants to purchase up to 1,458,314 shares of common stock that are issuable upon its exercise.

The Company entered into a Securities Purchase Agreement (the "***First Securities Purchase Agreement***"), dated April 9, 2025, by and between the Company, on the one hand, and Dr. Avi Katz, the Chairman of the Company's Board of Directors, and Dr. Raluca Dinu, the Chief Executive Officer and a member of the Company's Board of Directors, on the other hand (the "***April 2025 Private Placement***"). On April 24, 2025, at the closing of the April 2025 Private Placement, the Company issued (i) 261,644 shares of common stock at a per share purchase price of $1.911, which represented 110% of the volume weighted trading price for the common stock on April 9, 2025; and (ii) warrants with a term of ten years from the initial exercise date to purchase up to an additional 523,286 shares of common stock with a per share exercise price of $2.16. The aggregate gross proceeds to the Company from the April 2025 Private Placement was approximately $0.5 million, before deducting the offering expenses payable by the Company, which expenses consisted solely of legal fees. The Company used the net proceeds from the April 2025 Private Placement for working capital purposes.

On May 12, 2025, the Company entered into a Securities Purchase Agreement (the "***Second Securities Purchase Agreement***") for another PIPE investment (the "***May 2025 Private Placemen***t") in an amount of approximately $0.2 million, pursuant to which the Company issued 68,447 shares of common stock plus a PIPE Warrant to purchase 68,447 shares of common stock. The proceeds of this PIPE investment was used for working capital purposes. The May 2025 Private Placement provides a per share purchase price of $2.922, which represents 110% of the five-day volume weighted trading price for the common stock through May 9, 2025, and the per share exercise price of the warrant is $3.36.

On September 30, 2025, the Company entered into a Securities Purchase Agreement (the "***Third Securities Purchase Agreement***"), by and between the Company, on the one hand, and certain accredited investors and qualified institutional buyers, led by the Purchasers for the "***October 2025 Private Placement***." At the closing of the October 2025 Private Placement on October 3, 2025, the Company issued (i) 2,232,243 shares of our common stock, par value $0.0001 per share; (ii) Subscription PIPE Warrants with a term of five years from the initial exercise date to purchase up to an

------

additional 4,040,272 shares of common stock; and (iii) 5,424,083 pre-funded PIPE Warrants to purchase up to an additional 1,808,055 shares of common stock, exercisable any time after its issuance (the "***Pre-Funded Warrants***"). The purchase price of each share of common stock was $4.50 and the purchase price for each Pre-Funded Warrant was $4.4997. Both of these amounts were paid by the Purchasers at the closing of the October 2025 Private Placement. The aggregate gross proceeds to the Company from the October 2025 Private Placement was approximately $18.2 million, before deducting the offering expenses payable by the Company, which expenses consist solely of legal fees and the amounts provided for pursuant to a placement agency agreement The Company used the net proceeds from the offering for working capital purposes and to repay Tranche B of the Lynrock Lake Term Loan. The per share exercise price of each Subscription PIPE Warrant is $4.50 and the per share exercise price of each Pre-Funded Warrant is $0.0003.

As of December 31, 2025, there were a total 7,898,374 PIPE Warrants outstanding including the Pre-Funded Warrants.

In connection with the Lynrock Lake Term Loan, on February 26, 2025, the Company issued to Lynrock Lake, pursuant to the terms of the Lynrock Lake Warrant, a warrant to purchase 20,333,623 shares of common stock at an exercise price of $1.20 per share. The Lynrock Lake Warrant is exercisable until February 26, 2035. Lynrock Lake may cashless exercise the Lynrock Lake Warrant. The Lynrock Lake Warrant is also subject to anti-dilution adjustments to the exercise price and the number of shares which may be purchased upon exercise of the Lynrock Lake Warrant in the event that the Company issues shares of common stock (or derivative securities) at a price that is either less than the $1.20 exercise price or the fair market value of a share of common stock from the immediately prior trading day. On June 11, 2025, the Lynrock Lake Warrant was amended to update the provisions that would trigger cash settlement such that, when such events occur, the holders of the warrants receive the same form of consideration as the underlying stockholders. As equity classification is permitted for an instrument that requires net-cash settlement if the holders of the contract's underlying shares receive the same form of consideration in transactions outside the company's control, consequently the warrants were revalued and then reclassified to additional paid-in capital on the consolidated balance sheet upon modification. The fair value of the Lynrock Lake Warrant on modification date was $19.4 million. As of December 31, 2025, the Lynrock Lake Warrant to purchase 20,333,623 shares of common stock was outstanding.

On February 26, 2025, the Company issued to Yorkville a warrant to purchase 5,000,071 shares of its common stock at an exercise price of $1.20 per share pursuant to the Yorkville Warrant. The Yorkville Warrant is exercisable until February 26, 2030. On June 11, 2025, the Yorkville Warrant was amended to update the provisions that would trigger cash settlement such that, when such events occur, the holders of the warrants receive the same form of consideration as the underlying stockholders. As equity classification is permitted for an instrument that requires net-cash settlement if the holders of the contract's underlying shares receive the same form of consideration in transactions outside the company's control, consequently the warrants were revalued and then reclassified to additional paid-in capital on the consolidated balance sheet upon modification. The fair value of the Yorkville Warrant on modification date was $3.6 million. On August 26, 2025, the Company repurchased the Yorkville Warrant for an aggregate price of $5.0 million.

**11. Stock Incentive Plans**

*Inducement Equity Incentive Plan*

On August 22, 2025, the Company adopted the Inducement Equity Incentive Plan (the "***Inducement EIP***"), which authorized 108,333 shares of common stock. On November 14, 2025, the Company authorized an additional 220,000 shares of common stock under the Inducement EIP. RSUs to purchase 220,000 shares of common stock at a weighted-average fair value of $6.25 per share, were issued during the year ended December 31, 2025. There was no intrinsic value for the options outstanding as of December 31, 2025.

*2024 Equity Incentive Plan*

On February 15, 2024, at the Annual Meeting, the GigCapital5 stockholders considered and approved the 2024 Equity Incentive Plan (the "***2024 EIP***") and reserved 786,031 shares of common stock for issuance thereunder. The 2024 EIP became effective immediately upon the closing of the Business Combination on March 4, 2024. The term of the 2024 EIP is 10 years. The number of shares of common stock reserved for issuance under the 2024 EIP will automatically increase on January 1 of each year, beginning on January 1, 2025 and continuing through January 1, 2035, by 5% of the total number of shares of common stock outstanding on December 31 of the preceding calendar year, or a lesser number of shares as may be determined by the Board of Directors. Under the 2024 EIP, the Company may issue stock options, stock appreciation rights ("***SARs***"), restricted stock awards ("***RSAs***"), RSUs, and performance awards ("***PAs***"). The term of stock options may not exceed 10 years and is subject to vesting conditions, which is subject to the option holder's continued service to the Company. The exercise price of any stock option award cannot be less than fair market value of the Company's common stock, provided, however, that an incentive stock option granted to an employee who owns more than 10% of the total combined voting power of all classes of stock of the Company or any parent or subsidiary, must have an exercise price of no less than 110% of the fair market value of the Company's common stock and a term that does not exceed five years.

On January 1, 2025, an additional 446,137 shares of common stock were added to the 2024 EIP.

The following table summarizes information regarding activity in the 2024 EIP during the year ended December 31, 2025 (in thousands, except per share price):

(1)*Share amounts as of January 1, 2025 and prior to that date differ from those published in prior consolidated financial statements as they were retrospectively adjusted as a result of the Reverse Stock Split (As described in Note 1, The Company and Summary of Significant Accounting Policies). Specifically, the number of common stock outstanding during the periods before the Reverse Stock Split are divided by the exchange ratio of 3:1, such that each three shares of common stock were combined and reconstituted into one share of common stock effective October 23, 2025.*

(2)*The options outstanding as of December 31, 2024 were revised by 88,000 from the amount previously reported on the Annual Report on Form 10-K for the year ended December 31, 2024. The effect on stock-based compensation was immaterial.*

The determination of the fair value of options granted under the Inducement EIP and the 2024 EIP during the years ended December 31, 2025 and 2024 was computed using the Black-Scholes option pricing model with the following weighted-average assumptions:

---

| | | |
|:---|:---|:---|
| | **Year Ended December 31, 2025** | **Year Ended December 31, 2024** |
| Stock price per share | $3.40 | $2.16 |
| Expected option term (years) | 5.6 | 5.7 |
| Expected volatility | 71.4% | 67.9% |
| Risk-free rate of return | 4.0% | 4.3% |
| Expected annual dividend yield | —% | —% |
| Weighted-average grant date fair value | $2.21 | $1.38 |

---

Option pricing models require the input of various subjective assumptions, including the option's expected life and the price volatility of the underlying stock. The expected stock price volatility is based on the analysis of volatilities of the Company's selected public peer group over a period commensurate with the expected term of the options. The expected term of employee options represents the weighted-average period the options are expected to remain outstanding and was derived using the simplified method for awards that qualify for its "plain-vanilla" options. All awards that are outstanding are qualified for "plain-vanilla" options. The risk-free interest rate is based on the U.S. Treasury interest rates whose term in consistent with the expected life of the stock options. No dividend yield is included as the Company has not issued any dividends and does not anticipate issuing any dividends in the future.

*Stock-based Compensation*

The following table shows stock-based compensation expense by functional area in the consolidated statements of operations and comprehensive loss for the years ended December 31, 2025 and 2024:

Stock-based compensation expense capitalized to inventory for years ended December 31, 2025 and 2024 was insignificant.

As of December 31, 2025, the total unrecognized compensation cost related to all nonvested stock options and RSUs was $2.7 million and the weighted-average period over which it is expected to be recognized is 3.1 years.

Under the Tax Cuts and Jobs Act of 2017, research and development costs are no longer fully deductible and are required to be capitalized and amortized for U.S. tax purposes effective January 1, 2022. The mandatory capitalization requirement increases our gross deferred tax assets, which are fully offset by the valuation allowance. As of December 31, 2025, based on the Company's recent history of losses and its forecasted losses, management believes on the more-likely-than-not basis that a full valuation allowance is required. Accordingly, the Company provided a full valuation allowance on its federal and state deferred tax assets. During the years ended December 31, 2025 and 2024, the valuation allowance increased by $1.4 million and $5.9 million, respectively. As of December 31, 2025, the Company had federal and state net operating loss ("***NOL***") carryforwards of $27.3 million and $28.9 million respectively. The federal NOL will not expire and the state NOL will begin to expire in 2041.

The Internal Revenue Code ("***IRC***") of 1986, as amended, imposes restrictions on the utilization of net operating losses in the event of an "ownership change" of a corporation. Accordingly, a company's ability to use net operating losses may be limited as prescribed under IRC Section 382. Events which may cause limitations in the amount of the NOL that the Company may use in any one year include, but are not limited to, a cumulative ownership change of more than 50% over a three-year period. Utilization of the federal and state NOL may be subject to substantial annual limitation due to the ownership change limitations provided by the IRC Section 382 and similar state provisions.

A reconciliation of the beginning and ending amount of gross unrecognized tax benefits is a follows as of December 31, 2025 and 2024:

---

| | | |
|:---|:---|:---|
| *(in thousands)* | **December 31, 2025** | **December 31, 2024** |
| Balance as the beginning of the year | $49 | $49 |
| Increases related to prior year tax positions |  |  |
| Increases related to current year tax positions |  |  |
| Balance as the end of the year | $49 | $49 |

---

As of December 31, 2025 and 2024, the total amount of gross unrecognized tax benefits was $49 thousand, including interest and penalties of nil. As of December 31, 2025, none of the total unrecognized tax benefits, if recognized, would have an impact on the Company's effective tax. The Company estimates that there will be no material changes in its

------

uncertain tax positions in the next 12 months. The Company's policy is to recognize interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense.

The Company files income tax returns in the federal and California state jurisdictions. The Company is not currently undergoing any income tax examinations nor did any examinations occur for the tax years 2021 through 2024.

On July 4, 2025, the One Big Beautiful Bill Act ("***OBBBA***") was enacted into law. Among its provisions, OBBBA introduced Section 174, which allows for the immediate expensing of domestic research and experimental expenditures, reversing the amortization requirement enacted under the Tax Cuts and Jobs Act of 2017. Taxpayers may elect to expense such costs either entirely in the year incurred or ratably over a two-year period. The Company will elect to expense over a two-year period. As the Company has historically been in a loss position, the election to deduct domestic research and experimental expenditures will not have any impact to its financial results for the year ended December 31, 2025.

**14.&nbsp;&nbsp;&nbsp;&nbsp;Related Party Transactions**

***Convertible Notes Payable***

The Company's three convertible notes to three of its stockholders for advances up to $3.5 million in principal issued in July 2020 (the "***2020 Notes***") bear annual interest of 5% on any amounts drawn. The additional note issued in March 2022 as part of the 2020 Notes, has an annual interest rate of 8%. All principal and interest payments were initially due on or before July 1, 2025. In connection with the issuance of the Lynrock Lake Term Loan, on February 26, 2025, the maturity date on these convertible notes payable was extended to October 21, 2027.

The 2020 Notes are convertible, at the holder's option, into shares of common stock of the Company at the lower of $43.77 per share or the offering price in a financing of at least $5.0 million in equity from unaffiliated parties. As of December 31, 2025, an aggregate of 89,303 shares of common stock would be issued if the entire principal and interest under the 2020 Notes was converted. Management assessed whether the embedded features in the 2020 Notes should have been bifurcated from the debt host and concluded that none of the features were required to be accounted for separately from the debt instruments.

As of December 31, 2025 and 2024, the outstanding amount of the 2020 Notes was $3.2 million and $3.1 million, respectively, and accrued interest was $0.7 million and $0.6 million, respectively.

**Item 9: Changes in and Disagreements with Accountants on Accounting and Financial Disclosure**

None.

**Item 9A: Controls and Procedures**

*Evaluation of Disclosure Controls and Procedures*

Based on an evaluation under the supervision and with the participation of the Company's management, the Company's principal executive officer and principal financial officer have concluded that the Company's disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act were effective as of December 31, 2025 to provide reasonable assurance that information required to be disclosed by the Company in reports that it files or submits under the Exchange Act is (i) recorded, processed, summarized and reported within the time periods specified in the SEC rules and forms and (ii) accumulated and communicated to the Company's management, including its principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

*Inherent Limitations on Effectiveness of Controls*

The effectiveness of any system of internal control over financial reporting, including ours, is subject to inherent limitations, including the exercise of judgment in designing, implementing, operating, and evaluating the controls and procedures, and the inability to eliminate misconduct completely. Accordingly, in designing and evaluating the disclosure controls and procedures, management recognizes that any system of internal control over financial reporting, including ours, no matter how well designed and operated, can only provide reasonable, not absolute assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply its judgment in evaluating the benefits of possible controls and procedures relative to their costs. Moreover, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate. We intend to continue to monitor and upgrade our internal controls as necessary or appropriate for our business but cannot assure you that such improvements will be sufficient to provide us with effective internal control over financial reporting.

*Management's Annual Report on Internal Control Over Financial Reporting*

As discussed elsewhere in this Annual Report on Form 10-K, we completed the Business Combinations on March 4, 2024. Prior to the Business Combination, we were a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or other similar Business Combination with one or more target businesses. As a result, the internal controls of QT Imaging Holdings, Inc. ("***QT Imaging***") became our internal controls and were deemed not comprehensive enough as our operations prior to the Business Combination were insignificant compared to those of the consolidated entity post-Business Combination.

The design and implementation of internal control over financial reporting post-Business Combination has required and will continue to require significant time and resources from management and other personnel. Because of this, the design and ongoing development of our framework for implementation and evaluation of internal control over financial reporting has ultimately enabled management to conduct an assessment of the effectiveness of QT Imaging's internal control over financial reporting as of December 31, 2025. Accordingly, we are including herein management's report on internal control over financial reporting pursuant to the SEC's Regulation S-K 308(a).

*Previously Identified Material Weaknesses in Internal Control over Financial Reporting*

In connection with the preparation of our consolidated financial statements as of and for the fiscal year ended December 31, 2023, we identified a material weakness in our internal control over financial reporting related to lack of segregation of duties around key accounting processes resulting from limited personnel resources.

In connection with the review of our condensed consolidated financial statements as of and for the three months ended March 31, 2024, we identified a material weakness in our internal control over financial reporting related to technical accounting aspects of certain material transactions.

In connection with the audit of the consolidated financial statements as of and for the fiscal year ended December 31, 2024, we identified a misstatement in the condensed consolidated financial statements for the three-month period ended March

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_76)</u>**

31, 2024, six-month period ended June 30, 2024 and nine-month period ended September 30, 2024 as a result of a material weakness related to technical accounting.

There were no misstatements identified in the consolidated financial statements as of and for the year ended December 31, 2025 as a result of these material weaknesses.

*Management's Remediation Efforts in 2025*

To address the material weaknesses described above that we identified as of December 31, 2024, we implemented measures designed to improve our internal control over financial reporting during the year ended December 31, 2025. These measures included enhancing our internal and external technical accounting resources and engaging third party consultants for the formalization of our internal procedures. We completed documentation and tests of design and tests of operational effectiveness of our entity-level controls, certain areas of our information technology general computer controls ("***ITGCs***"), and controls over our business processes, and we remediated control gaps identified and performed tests of operating effectiveness on remediated items.

As a result of our remediation efforts, our management, under the supervision and with the participation of our Chief Executive Officer and our Chief Financial Officer and oversight of the Board of Directors, conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2025, based on the criteria set forth in Internal Control-Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework). Based on this evaluation, our management concluded that as of December 31, 2025, we no longer have the material weaknesses in internal control over financial reporting described above for entity-level controls and business process controls, which we previously identified existed as of December 31, 2024.

*Changes in Internal Control Over Financial Reporting*

Other than the remediation efforts related to the material weaknesses as described above, there were no changes in our internal control over financial reporting that occurred in the three months ended December 31, 2025 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

***Dr. Raluca Dinu*** co-founded GigCapital5 with Dr. Avi S.

She served as the Chief Executive Officer of GigCapital2, Inc.

She also served on the board of directors of GigCapital3, Inc.

("***GIG4***") until March 2024, and prior to the December 2021 business combination, was also the President, Chief Executive Officer and Secretary of GIG4 since its inception in December 2020. Drs. Katz and Dinu co-founded GigCapital7 Corp. ("***GIG7***") in May 2024, a Private-to-Public Equity (PPE) company formed for the purpose of acquiring a company in the TMT, AI/ML, cybersecurity, MedTech, semiconductor and sustainable industries, and Dr. Dinu has served on the board of directors of Gig7 since its inception. GIG7 completed its initial public offering in August 2024. Drs. Katz and Dinu co-founded GigCapital8 Corp. ("***GIG8***") in June 2025, a Private-to-Public Equity (PPE) company formed for the purpose of acquiring a company in the TMT, A&D and intelligent automation industries, and Dr. Dinu has served on the board of directors of GIG8 since its inception.

GIG9 completed its initial public offering in January 2026. Drs. Katz and Dinu also co-founded GigInternational1, a Private-to-Public Equity (PPE) company formed for the purpose of acquiring a company in the TMT, aerospace and defense, mobility and semiconductor industries with a particular emphasis on the EMEA market. GigInternational1 completed its initial public offering in May 2021, and Dr. Dinu served as a director beginning with the inception of GigInternational1 and as the Chief Executive Officer, President and Secretary of GigInternational1 beginning in March 2021. In November 2022, GigInternational1 decided to liquidate and dissolve the company rather than pursue a business combination, and in December 2022, GigInternational1 delisted from Nasdaq after liquidating its trust account. Dr. Dinu also holds a 50% membership interest in GigManagement, LLC, and has served as a managing member of GigManagement, LLC since its inception. From April 2017 to May 2019, Dr. Dinu was the Vice President and General Manager of IDT's Optical Interconnects Division. Prior to that, she held several executive-level positions at GigPeak, including Executive Vice President and Chief Operation Officer from April 2016 until it was acquired by IDT in April 2017, and before that, as its Executive Vice President of Global Sales and Marketing from August 2015 to April 2016, and as its Senior Vice President

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_76)</u>**

of Global Sales and Marketing from December 2014 to August 2015. From February 2014 to September 2017, Dr. Dinu was a member of the board of directors of Brazil-Photonics, in Campinas, Brazil, a joint venture that GigPeak established with the Centro de Pesquisa e Desenvolvimento em Telecomunicações (CPqD).

She also has a Corporate Director certificate from Harvard Business School, after completing the certification for Audit Committees and Compensation Committees in 2021 and Making Corporate Boards More Effective in 2022. Dr. Dinu is married to Dr. Katz, our Chairman of the Board.

We believe Dr. Dinu is qualified to serve on the Board based on her business experience as a board member of a publicly-listed company and her investing experience.

***Jay Jennings,*** *Chief Financial Officer.*

***Mr. Jennings*** has served as the Chief Financial Officer of QT Imaging since September 2025. Mr. Jennings is a seasoned accounting and finance executive who served in various executive level positions at UpHealth, Inc. since June 2021, when he began as the company's Chief Accounting Officer, and then became the company's Chief Financial Officer in October 2023 and Acting Chief Executive Officer in July 2024.

On February 22, 2019, GIG1 entered into a stock purchase agreement to acquire Kaleyra S.p.A. at about transaction enterprise value of $187 million with combined cash and/or promissory note consideration of $15 million. The transaction closed on November 25, 2019, and GIG1 was renamed Kaleyra, Inc. and listed on the NYSE American stock exchange under the symbol "KLR" (and since that time, Kaleyra uplisted to the NYSE). In November 2023, KLR was sold to Tata Communications at a transaction enterprise value of about $320 million in a cash deal and ceased to exist as a public company. Dr. Katz served as the Chairman of the board and Secretary of Kaleyra since the consummation of the transaction in November 2019 until the acquisition by Tata. In this capacity, Dr. Katz steered many restructurings and refinancings, including the acquisition of mGage from Blackstone for about $225

GIG4 completed its initial public offering in February 2021, in which it sold 35,880,000 units at a per unit price of $10.00, with each unit consisting of one share of GIG4 common stock and one-third (1/3) of one (1) warrant to purchase one share of GIG4 common stock, generating aggregate proceeds of about $359 million. GIG4 listed on Nasdaq under the symbol "GIG." In June 2021, GIG4 announced its agreement for a business combination with BigBear.ai Holdings, LLC. The business combination between GIG4 and BigBear.ai Holdings, LLC closed in December 9, 2021, and GIG4 was renamed BigBear.ai Holdings, Inc. BigBear.ai moved its listing from Nasdaq to the NYSE, where it is listed under the ticker symbol "BBAI." Dr. Katz served as the Executive Chairman of GIG4 from its inception until the closing of the business combination with BigBear.ai on December 9, 2021, and since then and until March 2024, has continued to serve as a member of the board of directors of BigBear.ai. In February 2021, Drs. Katz and Dinu co-founded GigInternational1, Inc. a Private-to-Public Equity (PPE) company formed for the purpose of acquiring a company in the TMT, aerospace and defense, mobility and semiconductor industries with a particular emphasis on the EMEA market. GigInternational1 completed its initial public offering in May 2021, in which it sold 20,900,000 units at a per unit price of $10.00, with each unit consisting of one share of GigInternational1 common stock and one-half (1/2) of one (1) warrant to purchase one share of GigInternational1 common stock, generating aggregate proceeds of $209 million. GigInternational1 listed on Nasdaq under the symbol "GIW," but in November 2022, decided to liquidate and dissolve the company rather than pursue a business combination, and in December 2022, GigInternational1 delisted from Nasdaq after liquidating its trust account. Dr. Katz was the Executive Chairman of GigInternational1 since its inception. Prior to launching his first Private-to-Public (PPE) company in 2017, Dr. Katz dedicated 10 years to incept and bootstrap, develop and manage GigPeak (NYSE American: formerly GIG), originally known as GigOptix, Inc. He served as Chairman of the Board, Chief Executive Officer and President of GigOptix / GigPeak from its inception in 2007 until its sale in April 2017 to IDT International (Nasdaq: IDTI) for $250 million in cash. While Dr. Katz was at GigPeak's helm, the company completed 10 M&A deals. From 2003 to 2005, Dr. Katz was the chief executive officer, president, and member of the board of directors of Intransa, Inc. From 2000 to 2003, Dr. Katz was the chief executive officer, president and a member of the board of directors of Equator Technologies. Prior to it, Dr. Katz held several leadership positions over the span of his career within the TMT industry since serving as member of Technical Staff at AT&T Bell Laboratories between 1988 and 1994, and made numerous angel investments in high-tech companies around the world, being a serial entrepreneur. He holds many U.S. and international patents, authored and co-authored more than 350 published scientific and technical articles in reputable journals, and is the editor of a number of technical books. Dr. Katz is a global philanthropist, and among many other activities, serves as board member of the NY Philharmonic Company. He is a graduate of the 1976 class of the Israeli Naval Academy, graduate of the 1979 USA Naval ASW class, and holds a B.Sc. and Ph.D. in Materials from the Technion (Israel Institute of Technology). Dr. Katz is married to Dr. Dinu, our Chief Executive Officer and one of our directors.

We believe that Dr. Katz is qualified to serve as Chairman of the Board based on his business experience as a founder, inventor, chief executive officer and director of a publicly-listed company and his investing experience.

Mr. Dickson began his executive management career in 1980, when he joined General Electric Company. From 1980 until 1987, he held a number of strategic and operational roles and had responsibility for a $300 million business in the company's consumer electronics division. In 1987, Mr. Dickson left GE to join a startup company that brought advanced technology to consumer products retailing.

Based on this experience, he joined The Brenner Group, Inc., in 1998 where he built that company's interim CEO practice. During that period, he also served as a "parachute" CEO and was retained by multiple San Francisco Bay Area venture firms to manage and reposition their portfolio companies, including Armus Corporation, a data management firm that focused on medical outcomes (acquired by Health Catalyst Capital Management in 2022), and Vital Transport, a start-up company involved in organ transport.

After doubling sales and creating a significant internet business, he negotiated the company's acquisition by the $9 billion publicly held Great Atlantic & Pacific Grocery chain in 2007. After the acquisition, Mr. Dickson was retained as a "virtual COO" for the company's $200 million wine, beer, and spirits operation, where he remained until 2011.

**Director Independence** 

The Board undertook a review of the independence of each director. Based upon information requested from and provided by each director concerning their background, employment, and affiliations, including family relationships, the following members of the Board do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is "independent" as that term is defined under Nasdaq rules: Ross Taylor, Daniel Dickson, James Greene and Professor Zeev Weiner.

In making these determinations, the Board has considered the current and prior relationships that each non-employee director has with the Company and all other facts and circumstances that the Board deems relevant in determining their independence, including the beneficial ownership of the Company's capital stock by each non-employee director, and the transactions involving them described in the section titled "*Certain Relationships and Related Party Transactions*." Other than that Drs. Katz and Dinu are married to each other, there are no family relationships among any of the directors or executive officers of the Company.

**Board Responsibilities and Structure**

The Board oversees, counsels, and directs management in the long-term interests of QT Imaging and our stockholders. The Board's responsibilities include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• selecting, evaluating the performance of, and determining the compensation of the Chief Executive Officer and other executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• planning for succession with respect to the position of Chief Executive Officer and monitoring management's succession planning for other executive officers;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• overseeing the processes for maintaining our integrity with regard to our financial statements and other public disclosures, and compliance with law and ethics.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The Board and its committees met throughout the year on a set schedule, held special meetings, and acted by written consent from time to time as appropriate.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Board Leadership Structure*. The Board has leadership in the form of a Chairman of the Board. The Bylaws establish a fixed policy regarding the separation of the offices of Chairman of the Board and Chief Executive Officer. In accordance with this policy, the Board maintains a separate Chairman of the Board who is not the Chief Executive Officer of QT Imaging. The duties of the Chairman of the Board include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• presiding over all meetings of the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• •preparing the agenda for Board meetings in consultation with the Chief Executive Officer and other members of the Board;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• general supervision and control of the acquisition and financing activities of the Company; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• presiding over all meetings of stockholders.

**Role of Board in Risk Oversight** 

The Board has an active role, as a whole and also at the committee level, in overseeing the management of the Company's risks. The Board is responsible for general oversight of risks and regular review of information regarding the Company's risks, including credit risks, liquidity risks, and operational risks. The Compensation Committee is responsible for overseeing the management of risks relating to the Company's executive compensation plans and arrangements. The Audit Committee is responsible for overseeing the management of risks relating to accounting matters and financial reporting and potential conflicts of interest. The Nominating and Corporate Governance Committee is responsible for overseeing the management of risks associated with the independence of the Board. Although each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through discussions from committee members about such risks.

**Board Composition and Classification** 

The Board consists of seven members. In accordance with the Charter, the Board is classified. The Board believes it is in the best interests of the Company for the Board to be classified into three classes, each comprising as nearly as possible one-third of the directors to serve three-year terms, and only one class of directors will be elected at each annual meeting of

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_76)</u>**

stockholders, with the other classes continuing for the remainder of their respective three-year terms. The Board consists of the following members:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Class I directors are Daniel Dickson and James Greene and their terms will expire at the annual meeting of stockholders to be held in 2028;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Class II directors are Ross Taylor and Professor Zeev Weiner and their terms will expire at the annual meeting of stockholders to be held in 2026; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the Class III directors are Dr. Avi S. Katz, Dr. Raluca Dinu and Dr. John Klock and their terms will expire at the annual meeting of stockholders to be held in 2027.

At each annual meeting of stockholders, upon the expiration of the term of a class of directors, the successor to each such director in the class will be elected to serve from the time of election and qualification until the third annual meeting following their election and until their successor is duly elected and qualified, in accordance with the Charter. Any additional directorships resulting from an increase in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the Company's directors.

This classification of the Company's directors may have the effect of delaying or preventing changes in control of the Company.

**Board Committees** 

The standing committees of the Board consist of the Audit Committee, the Compensation Committee and a Nominating and Corporate Governance Committee, each of which has the composition and the responsibilities described below. Additionally, from time to time, special committees may be established under the direction of the Board when the Board deems it necessary or advisable to address specific matters.

In addition, the Charter provides that our directors will not be personally liable for monetary damages to us or our stockholders for breaches of their fiduciary duty as directors, unless they violated their duty of loyalty to us or our stockholders, acted in bad faith, knowingly or intentionally violated the law, authorized unlawful payments of dividends, unlawful stock purchases or unlawful redemptions, or derived an improper personal benefit from their actions as directors.

The Company has entered into agreements with our officers and directors to provide contractual indemnification in addition to the indemnification provided for in our Charter. The Company's Bylaws also permit us to secure insurance on behalf of any officer, director or employee for any liability arising out of his or her actions, regardless of whether Delaware law would permit such indemnification. We purchase a policy of directors' and officers' liability insurance that insures our officers and directors against the cost of defense, settlement or payment of a judgment in some circumstances and insures us against our obligations to indemnify our officers and directors.

These provisions may discourage stockholders from bringing a lawsuit against our directors for breach of their fiduciary duty. These provisions also may have the effect of reducing the likelihood of derivative litigation against officers and directors, even though such an action, if successful, might otherwise benefit us and our stockholders. Furthermore, a stockholder's investment may be adversely affected to the extent we pay the costs of settlement and damage awards against officers and directors pursuant to these indemnification provisions.

We believe that these provisions, the directors' and officers' liability insurance and the indemnity agreements are necessary to attract and retain talented and experienced officers and directors.

**Insider Trading Policy**

We have adopted an insider trading policy governing the purchase, sale and/or other dispositions of its securities by its directors, officers and employees that we believe is reasonably designed to promote compliance with insider trading laws, rules and regulations and the Nasdaq listing standards. The foregoing summary of our insider trading policy does not purport to be complete and is qualified in its entirety by reference to the full text thereof attached hereto as Exhibit 19.1.

**Item 11: Executive Compensation**

**Compensation Discussion and Analysis**

The following discussion and analysis of our executive compensation philosophy, objectives and design, our compensation-setting process, the components of our executive compensation program, and the decisions made for compensation in respect of 2025 for our executive officers should be read together with the compensation tables and related

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_76)</u>**

disclosures set forth below. The discussion in this section contains forward-looking statements that are based on our current considerations and expectations relating to our executive compensation programs and philosophy. As our business and our needs evolve, the actual amount and form of compensation and the compensation programs that we adopt may differ materially from current or planned programs as summarized in this section.

**Overview**

This section provides an overview of our executive compensation program, including a narrative description of the material factors necessary to understand the information disclosed in the summary compensation table below.

In evaluating our overall executive compensation program and decisions for the 2025 fiscal year, including awards under our compensation programs, the Compensation Committee considered a number of factors, including that 2024 was our first year operating as a public company, incentivizing the achievement of both strategic enterprise and financial objectives and our position as a transformational company. Going forward, the Compensation Committee will be making any determinations as it relates to the payout of the previous year's compensation programs as well as the adoption of any performance measures for the current fiscal year. This allows the Compensation Committee to have a good understanding of the prior fiscal year financial performance in order to evaluate the performance of our named executive officers (each, a "***NEO***") against previously adopted performance measures as well as develop plans and performance metrics based on the annual operating plan for the current fiscal year.

For the year ended December 31, 2025, our NEOs were:

|:---|:---|:---|
| **Name** | **Age** | **Position** |
| Dr. Raluca Dinu<sup>(1)</sup> | 51 | Chief Executive Officer and Director (Class III) |
| Jay Jennings<sup>(3)</sup> | 58 | Chief Financial Officer |
| Anastas Budagov<sup>(4)</sup> | 37 | Former Chief Financial Officer |

---

______________

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)Dr. Raluca Dinu has served as our Chief Executive Officer and Class III Director since March 12, 2024, when she was appointed by the Board to replace Dr. John C. Klock, effective immediately.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)On August 22, 2025, the Board appointed Mr. Jay Jennings to serve as our Chief Financial Officer, effective September 2, 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(3)Mr. Budagov served as our Chief Financial Officer since December 2023 and until August 29, 2025, when he was replaced by the Board with Mr. Jennings.

**Compensation Philosophy and Objectives**

The Company has developed an executive compensation program that is consistent with the compensation policies and philosophies of the Compensation Committee and the Board, which are designed to align compensation with the Company's business objectives and the creation of stockholder value, while enabling the Company to attract, motivate and retain individuals who contribute to its long-term success. Decisions on the executive compensation program are made by the Compensation Committee.

The objectives of the Company's executive compensation program are to encourage retention and recruitment of high-performing executives, to motivate employees and align executive interests across the organization and with the Company's stockholders, to reward sustainable financial performance, accountability and innovation, to create consistence with the Company's strategy and culture (mission, vision and values) and to balance innovation and performance with risk. In setting executive compensation in 2025, the Compensation Committee took into account the Company's strategy, culture and stage in defining plan feature tradeoffs. The Compensation Committee also looked to manage exceptions to its approach based upon the individual profiles of various members of the Company's management.

Decisions regarding executive compensation reflect a belief that the executive compensation program must be competitive in order to attract and retain highly competent executive officers as well as include a significant element of "pay for performance." Total compensation will be comprised of base salary, short-term incentive and long-term incentive. A significant portion of compensation for the members of management of the Company is tied to annual performance objectives. All elements of the compensation are defined in absolute dollar values. Further, the Compensation Committee seeks to tie our executive compensation levels to the compensation practices of our peer companies.

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_76)</u>**

**Base Salary**

Base salaries for our NEOs are established based on the individual's scope of responsibilities, experience and market factors. The base salary is an annual total cash salary paid over 12 months in equal amounts. The Compensation Committee typically reviews base salaries on an annual basis, referencing peer group and survey data to understand the marketplace for individuals in similar positions. No formulaic base salary increases are provided to our NEOs; however, annual merit increases are provided when the Compensation Committee determines that such increases are warranted in light of national salary increase levels, salary levels within companies in our peer group, individual performance and/or overall Company performance. We pay base salaries to attract, recruit and retain qualified employees. The base salaries for 2025 for our NEOs take into account the initial base amount set forth in the executive's respective employment agreement or employment offer letter, as applicable, and the scope of the executive's responsibilities, individual contributions, prior experience and sustained performance.

| Jay Jennings<sup>(3)</sup> | $400000 |

________________

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(1)On August 28, 2025, our Board approved an increase in the base salary for Dr Raluca Dinu effective September 1, 2025. Prior to this increase Dr. Dinu's base salary was $470,000 per year based on her employment agreement dated March 12, 2024. In addition, on March 20, 2026, our Board approved an increase in the base salary for Dr. Dinu effective that same day to $605,000 per year.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(2)Mr. Jennings' base salary is based on his employment agreement dated August 22, 2025.

**Annual Bonuses**

The Company uses annual cash incentive bonuses for the NEOs to tie a portion of their compensation to financial and operational objectives achievable within the applicable fiscal year. The annual cash incentive bonus is expressed as a percentage of an individual's base salary. The Compensation Committee set the performance targets using two financial metrics for the 2025 fiscal year: total revenue; and cash balance. Determination of the achievement of the targets is based upon the full year financial results following the completion of the audit of the Company's consolidated financial statements. Following the end of the year, the Compensation Committee will determine the extent to which the performance targets were achieved and the amount of the award that will payable to the NEOs.

**Equity-Based Awards**

The Company uses equity-based awards to reward long-term performance of the NEOs. The Company believes that providing a meaningful portion of the total compensation package in the form of equity-based awards aligns the incentives of its NEOs with the interests of its stockholders and serves to motivate and retain the individual NEOs. Any awards would be made in accordance with the executive compensation program discussed above. Although the Company has not used a specific predetermined schedule to grant equity-based awards as 2024 was the first year that the Company made such awards as a public company, it is the policy of the Company regarding our grants of equity-based awards that the Company does not (a) backdate equity award grants, (b) time the public release of material information or (c) purposely accelerate or delay equity award grants with the intent of allowing an award recipient to benefit from a more favorable stock price. The Company is currently using time-based stock option awards to encourage long term performance.

**Other Compensation**

The Company maintains various employee benefit plans, including medical, dental, life insurance and 401(k) plans, in which the NEOs may participate. It also provides certain perquisites to its NEOs, subject to the Compensation Committee's ongoing review.

**Deductibility of Executive Compensation**

Section 162(m) of the Code denies a federal income tax deduction for certain compensation in excess of $1.0 million per year paid to the chief executive officer, the chief financial officer, the three other most highly paid executive officers of a publicly traded corporation, and anyone previously subject to Section 162(m) as a covered employee for any taxable year

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_76)</u>**

beginning after December 31, 2016. It is the policy of the Company to consider the tax impact of its compensation arrangements as one factor, among others, in evaluating and determining the structure, implementation, and amount of awards paid to its executive officers. However, to retain highly skilled executives and remain competitive with other employers, the Compensation Committee may authorize compensation that would not be deductible under Section 162(m) or otherwise if it determines that such compensation is in the best interests of the Company and its stockholders, and maintaining tax deductibility will not be the sole consideration taken into account in determining what compensation arrangements are in our and our stockholders' best interests. The right to grant compensation that is not deductible is expressly reserved, and the Company may do so.

**Summary of Compensation Table**

The table below sets forth the annual compensation levels of our NEOs for 2025 and 2024, who as a smaller reporting company consist of the principal executive officer who serves as Chief Executive Officer of QT Imaging, and the next two most highly compensated executive officers. The compensation totals and individual amounts reflect the compensation of such officers by the Company or QT Imaging as of December 31, 2025 and 2024. In the fiscal year 2026, such totals and amounts may change based on, among other things, changes to the terms of the employment of such persons.

**Employment Arrangements with Named Executive Officers**

*Employment Agreement with Dr. Raluca Dinu*

On August 28, 2025, the Board approved an increase in the base salary and the target annual bonus for Dr. Raluca Dinu, the Company's Chief Executive Officer, effective as of September 1, 2025. Prior to this increase, Dr. Dinu's base salary was $470,000 per year and her target annual bonus was 65% of her salary, and effective as of September 1, 2025, Dr. Dinu's base salary is $550,000 per year and her target annual bonus is 75% of her salary. In addition, on March 20, 2026, our Board approved an increase in the base salary for Dr. Dinu effective that same day to $605,000 per year.

On March 12, 2024, the Board appointed Dr. Raluca Dinu, who is also a member of the Board, to be employed as its Acting Chief Executive Officer effective as of March 12, 2024. Dr. Dinu will report to the Board. On March 18, 2024, the Board approved an employment agreement (the "***CEO Employment Agreement***") between Dr. Dinu and the Company, effective as of March 12, 2024, governing the terms of Dr. Dinu's employment by the Company, which the Company and Dr. Dinu then entered into.

Under the terms of the CEO Employment Agreement, Dr. Dinu will be hired on an "at will" basis and shall serve as the Company's Chief Executive Officer on an interim but full-time basis, performing her duties and responsibilities in such capacity. The CEO Employment Agreement provides that Dr. Dinu will serve as the Company's Chief Executive Officer until the earlier of the twelve (12) month anniversary of the Effective Date or the date on which her employment is terminated in accordance with the terms of CEO Employment Agreement, but that the term of the CEO Employment Agreement may be renewed by written agreement between Dr. Dinu and the Company. Dr. Dinu's employment is "at will" and terminable by the Company at any time and for any reason or no reason, including as a result of her death or disability, as provided in the CEO Employment Agreement, and with or without "cause". Dr. Dinu may terminate her employment with the Company at any time and for any reason or no reason, including with or without "good reason".

The Company will pay Dr. Dinu a base salary at the initial annualized rate of $470,000 per year, subject to standard deductions and withholdings, or such other rate as may be determined from time to time by the Board or the Compensation

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_76)</u>**

Committee (hereinafter referred to as the "***CEO Base Salary***"). Such CEO Base Salary will be paid in accordance with the Company's standard payroll practice. The CEO Base Salary will be reviewed annually and Dr. Dinu will be eligible to receive a salary increase annually, during the compensation cycle, in an amount to be determined by the Board or the Compensation Committee in its sole and exclusive discretion. Once adjusted, the new salary will become the CEO Base Salary for purposes of the CEO Employment Agreement.

Dr. Dinu will, in accordance with Company policy and the terms of the applicable plan documents, be eligible to participate in benefits under any executive benefit plan or arrangement which may be in effect from time to time and made available to the Company's executives or key management employees. Dr. Dinu will be eligible to accrue up to sixty days of paid time off per year, in accordance with the Company's policies as in effect from time to time. The Company will pay or reimburse all reasonable, customary and necessary business expenses, subject to any maximum annual limit or other restrictions as set by the Board or its designated committee.

For each fiscal year of the Company ("***FY***") completed during the term of Dr. Dinu's employment as Chief Executive Officer, Dr. Dinu shall have the opportunity to earn an annual bonus ("***CEO Annual Bonus***") under the executive incentive plan then applicable to executives of the Company generally, as in effect from time to time, with the actual amount of each CEO Annual Bonus being determined by the Board or its designated committee based on the achievement of target objectives established by the Board or its designated committee after consultation with Dr. Dinu, and for which the target of the CEO Annual Bonus is an amount equal to 65% of the annual Base Salary during the specific FY. Any CEO Annual Bonus due to Dr. Dinu will be payable not later than two and one-half months following the close of the FY for which the bonus was earned. Except as otherwise provided in the CEO Employment Agreement, Dr. Dinu must be employed on the date annual bonuses are paid under the Company's executive incentive plan in order to be eligible to earn an CEO Annual Bonus for the preceding FY.

Dr. Dinu shall also have the opportunity to earn a bonus (the "***Special Achievement Bonus***") upon completion of acquisitions or sales (in each case, whether by merger, asset purchase or stock purchase, or any other method as approved by the Board), or other special activities that generate value to the Company as recognized by the Board or a designated committee of the Board, including, but not limited to, the Compensation Committee, as being eligible for such special achievement bonus. To the extent any of the mentioned above activities are recognized, in good faith, by the Board (or its designated committee) as being eligible for a Special Achievements Bonus, then Dr. Dinu shall have the right to present a proposed bonus structure to the Board, who shall consider the benefit of the activity to the Company's stockholders, the nature of the activity, the benefits of the activity to the Company's technology, business development, or cash position and such other factors as the Board and Dr. Dinu agree in good faith are relevant and appropriate. Whether any Special Achievement Bonus is paid and the amount of any such bonus, shall be in the sole discretion of the Board (or its designated committee).

The CEO Employment Agreement provides for the grant of equity awards, in a form to be determined, in the amount of 550,000 shares of common stock to Dr. Dinu, pursuant to and subject to the terms of the Company's 2024 Equity Incentive Plan (the "***2024 EIP***"), and subject to approval by the Board and the filing of an effective registration statement on Form S-8 by the Company. Any further equity awards shall be at the discretion of the Board or its designation committee. All of the outstanding and unvested awards held by Dr. Dinu shall vest in the event of a change in control, and if the awards require exercise, be exercisable for the duration of the maximum permitted exercise period as set forth in such grant or grants from the Board, and all of the remaining undelivered shares shall be delivered for such awards that are of stock units immediately prior to and contingent upon the change of control, to the extent delivery will not result in adverse Section 409A tax consequences.

In the event of a change in control, the Company will pay Dr. Dinu the following payments, subject to her continued service through the closing of such change of control transaction and her return of a release of claims: (i) to the extent not already paid, the target amount of the CEO Annual Bonus (the "***Target Bonus***") for the entire FY in which the change in control occurs, and (ii) a lump sum equal to (A) two (2) years of (a) the CEO Base Salary in effect and (B) the average of the entire CEO Annual Bonuses and Special Achievement Bonuses paid to Dr. Dinu for the two FYs completed prior to the change of control, as applicable, or, if only one such FY has been completed, then based on the amount of the CEO Annual Bonus and the Special Achievement Bonus for such FY (the "***CEO Bonus***") (not including however in calculating the Bonus, any Special Achievement Bonus payable for the change of control transaction shall not be included in determining the entire Annual Bonuses and Special Achievement Bonuses). The occurrence of a change of control will trigger the vesting of all outstanding, unvested awards held by Dr. Dinu and a potential tax equalization payment or gross-up payment which would place Dr. Dinu in the same after-tax position as if any excise tax penalty did not apply with respect to compensation received by Dr. Dinu in connection with such change in control. For the purposes of the CEO Employment Agreement, a "change of control" means the occurrence of one or more of the following: (i) any "Person" or "group,"

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_76)</u>**

within the meaning of Section 13(d)(3) or 14(d)(2) of the Exchange Act, other than the Company or any of its affiliates, becomes a beneficial owner, directly or indirectly, in one or a series of transactions, of securities representing fifty percent or more of the total number of votes that may be cast for the election of directors of the Company; (ii) the consummation of a merger or consolidation of the Company with any other person (other than a member of the Company and/or its affiliates), other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) more than fifty percent of the total voting power represented by the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation; (iii) within twelve months after a tender offer or exchange offer for voting securities of the Company (other than by the Company) the individuals who were directors of the Company immediately prior thereto shall cease to constitute a majority of the Board; or (iv) there occurs a closing of a sale or other disposition by the Company of all or substantially all of the assets of the Company other than to one or more of the Company's affiliates.

Dr. Dinu would be entitled to receive certain compensation if her employment with the Company is terminated without "cause" or she resigns for "good reason" (as those terms are defined in the CEO Employment Agreement) in the absence of a change of control transaction, including (i) six months' of her annual base salary then being paid, payable in equal monthly installments, (ii) a final pro-rated bonus for the period of the year that she has worked prior to termination, (iii) additional compensation equal to eighteen months of Dr. Dinu's base salary then in effect plus two times the amount of the CEO Bonus (with "CEO Bonus" being defined as the average of the entire CEO Annual Bonuses and Special Achievement Bonuses (each, as defined in the CEO Employment Agreement) paid to Dr. Dinu for the two fiscal years completed prior to her termination), payable in a lump sum subject to certain conditions more fully described in the CEO Employment Agreement.

In the event that Dr. Dinu's employment is terminated as a result of her death, the Company shall pay to her estate within sixty days of the date of termination (the "***Date of Termination***") (i) the CEO Base Salary earned but not paid as of the Date of Termination and any un-reimbursed business expenses (together, the "***CEO Final Compensation***"), (ii) twelve months' CEO Base Salary in effect as of Date of Termination, (iii) the Target Bonus for the FY in which the Date of Termination occurs, and (iv) the full premium health and dental plan coverage for each of Dr. Dinu's qualified beneficiaries for the later of the expiration of the term of the CEO Employment Agreement or one year following the Date of Termination, or until COBRA is no longer available to such beneficiaries (the "***Beneficiary Benefits***").

If Dr. Dinu's employment is terminated as a result of a disability (as defined in the CEO Employment Agreement), then, in addition to the Final Compensation, payable as a lump sum as of March 15th of the year following the Date of Termination, the Company will pay Dr. Dinu a pro-rated CEO Annual Bonus for the year during which the Date of Termination takes place, as determined by the Board, and the Beneficiary Benefits.

In the event that Dr. Dinu is terminated with "cause" (as is defined in the CEO Employment Agreement), then the Company shall make no payments to Dr. Dinu other than provision of the CEO Final Compensation, payable no later than ten days after the Date of Termination. Any equity in the Company held by Dr. Dinu in such case shall be governed by the terms of the Company's equity incentive plans.

If the Company terminates Dr. Dinu or Dr. Dinu terminates her employment for any reason, and a change in control has occurred within twelve months prior to the Date of Termination, then subject to Dr. Dinu's providing a release of claims and compliance with surviving obligations, including confidentiality, the Company shall provide health and dental plan coverage for Dr. Dinu and her beneficiaries for at most two years.

If Dr. Dinu terminates her employment upon sixty days' notice, other than for "good reason" and a change in control has not occurred, if the Board so elects, the Company will pay her the CEO Base Salary for the initial sixty days of the notice period in accordance with usual payroll practices.

Such CFO Base Salary will be paid in accordance with the Company's standard payroll practice. The CFO Base Salary will be reviewed annually and Mr. Jennings will be eligible to receive a salary increase annually, during the compensation cycle, in an amount to be determined by the Board or the Compensation Committee in its sole and exclusive discretion. Once adjusted, the new salary will become the CFO Base Salary for purposes of the CFO Employment Agreement.

Mr. Jennings will, in accordance with Company policy and the terms of the applicable plan documents, be eligible to participate in benefits under any executive benefit plan or arrangement which may be in effect from time to time and made available to the Company's executives or key management employees.

Any Annual Bonus payable to Mr. Jennings will be payable not later than two and one-half months following the close of the calendar year to which it pertains. Except as otherwise provided in the CFO Employment Agreement, Mr. Jennings must be employed on the date annual bonuses are paid in order to be eligible and earn an Annual Bonus for the calendar year to which the bonus pertains.

The CFO Employment Agreement provides for the grant of equity awards, in a form to be determined, in the amount of 325,000 shares of common stock to Mr. Jennings, pursuant to and subject to the terms of the Company's Inducement Equity Incentive Plan, adopted on August 22, 2025, subject to approval by the Board and the filing of an effective registration statement on Form S-8 by the Company.

In the event of a Change in Control (as defined in the CFO Employment Agreement), the Company will grant to Mr. Jennings the following, subject to his continued service through the closing of such change of control transaction and effectiveness of a release of claims in favor of the Company: (i) an amount equal to nine months of his then-current CFO Base Salary, (ii) to the extent not already paid, a pro-rated Annual Bonus for the calendar year in which the termination occurs, (iii) if participating in the Company's health benefits, coverage for his insurance premium, including any amounts that the Company paid for benefits to his qualified family members, until the earlier of (A) nine months following his termination date or (B) the date on which Mr. Jennings begins full-time employment with another company or business entity offering comparable health insurance coverage, and (iv) notwithstanding anything in the applicable option agreement or stock-based award agreement, immediate acceleration of all stock options and other stock-based awards.

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_76)</u>**

in which the stockholders of the Company immediately before the Transaction do not retain immediately after the Transaction direct or indirect beneficial ownership of more than fifty percent (50%) of the total combined voting power of the outstanding securities entitled to vote generally in the election of Directors or, in the case of an Ownership Change Event described in Section 2.1 of the CFO Employment Agreement, the entity to which the assets of the Company were transferred, as the case may be and (iii) a date specified by the Committee following approval by the stockholders of a plan of complete liquidation or dissolution of the Company; provided, however, that a Change in Control shall be deemed not to include a transaction described in subsections (i) or (ii) of Section 2.1(h) of the CFO Employment Agreement in which a majority of the members of the board of directors of the continuing, surviving or successor entity, or parent thereof, immediately after such transaction is comprised of Incumbent Directors.

Mr. Jennings would be eligible to receive certain severance compensation if his employment with the Company is terminated without "Cause" of if he resigns for "Good Reason" (as those terms are defined in the CFO Employment Agreement) in the absence of a Change of Control transaction, conditioned upon effectiveness of a release of claims in favor of the Company. The severance comprises (i) nine months of his then-current annual base salary, payable in equal monthly installments over nine months following the date on which the release of claims becomes effective, (ii) if participating in the Company's health benefits, coverage for his insurance premium, including any amounts that the Company paid for benefits to his qualified family members, until the earlier of (A) the date that is nine months from his termination date or (B) the date on which Mr. Jennings begins full-time employment with another company or business entity offering comparable health insurance coverage, and (iii), immediate vesting of equity awards through the next scheduled vesting date for such equity awards following the date on which the release of claims becomes effective.

***Data Use and License Agreement***

On January 23, 2025, the Company entered into a Sublease Agreement (the "***Sublease***") with the Practice, pursuant to which the Practice will sublease certain space, currently leased from Hamilton Landing Novato LLC by the Company pursuant to the "Prime Lease" (as defined in the Sublease), to the Practice for use in its operations, on a full-time and exclusive basis. The Practice shall pay to the Company a rental fee (the "Rent") for the Subleased Space (as defined in the Sublease) in an amount equal to $5,666.00 until May 31, 2025, with such amount increasing to $5,836.24 during the period from June 1, 2025 until May 31, 2026, and subsequently $6,011.33 during the period from June 1, 2026 until May 31, 2027.

The parties have determined that the Rent equals the fair market value of the Subleased Space (as defined in the Sublease), without taking into account the proximity of the parties or the Subleased Space to any source, volume or value of referrals between the parties or any patient thereof. Further, the Practice shall pay when due all sales, use, personal property, leasing, excise or other fees, taxes, charges or withholdings of any kind imposed against the Company, the Practice or the Subleased Space with respect to the Subleased Space, or any related fees, receipts or earnings, including local taxes and personal property taxes. The term of the Sublease is one year unless terminated and shall auto-renew on a month-to-month basis thereafter, unless otherwise terminated. The Sublease shall expire automatically upon the termination of the Prime Lease, which is set to terminate in April 2027.

**Related Person Transactions Policy** 

The Board expects to adopt a related person transaction policy that will set forth the Company's procedures for the identification, review, consideration and approval or ratification of related person transactions. The policy became effective upon approval by the Board following the consummation of the Business Combination. The Company's audit committee will have the primary responsibility for reviewing and approving or disapproving "related party transactions." The charter of the Company's audit committee will provide that the audit committee will review and approve in advance any related party transaction.

A related person transaction is a transaction, arrangement or relationship, or any series of similar transactions, arrangements or relationships, between the Company and related persons in which the aggregate amount involved exceeds or may be expected to exceed $120,000 and in which a related person has or will have a direct or indirect material interest. Transactions involving compensation for services provided to the Company as an employee or director are not expected to be covered by this policy. A related person is any executive officer, director or beneficial owner of more than 5% of any class of the Company's voting securities and any of their respective immediate family members and any entity owned or controlled by such persons.

------

**<u>[**Table of Contents**](#i15dc7b469ca341bba04289f3a00cc736_76)</u>**

It is expected that under the policy, if a transaction has been identified as a related person transaction, including any transaction that was not a related person transaction when originally consummated or any transaction that was not initially identified as a related person transaction prior to consummation, the Company's management must present information regarding the related person transaction to the Company's audit committee, or, if audit committee approval would be inappropriate, to another independent committee of the Board, for review, consideration ,and approval or ratification. The presentation must include a description of, among other things, the material facts, the interests (direct and indirect) of the related persons, the benefits to the Company of the transaction and whether the transaction is on terms that are comparable to the terms available to or from (as the case may be) an unrelated third party or to or from employees generally. Under the policy, the Company will collect information that it deems reasonably necessary from each director, executive officer and, to the extent feasible, significant stockholder to enable the Company to identify any existing or potential related person transactions and to effectuate the terms of the policy. In addition, under the Code of Business Conduct and Ethics that the Company expects the Board to adopt following the closing of the Business Combination, the Company's employees and directors will have an affirmative responsibility to disclose any transaction or relationship that reasonably could be expected to give rise to a conflict of interest. In considering related person transactions, it is expected that the Company's audit committee, or other independent committee of the Board, will take into account the relevant available facts and circumstances including, but not limited to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the risks, costs and benefits to the Company;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the impact on a director's independence in the event that the related person is a director, immediate family member of a director or an entity with which a director is affiliated;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the availability of other sources for comparable services or products; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• the terms available to or from, as the case may be, unrelated third parties or to or from employees generally.

It is also expected that the policy will require that, in determining whether to approve, ratify or reject a related person transaction, the Company's audit committee, or other independent committee of the Board, will consider, in light of known circumstances, whether or not the transaction is consistent with the Company's best interests and those of the Company's stockholders, as the Company's audit committee, or other independent committee of the Board, determines in the good faith exercise of its discretion.

**Director Independence** 

The Board has undertaken a review of the independence of each director. Based upon information requested from and provided by each director concerning their background, employment, and affiliations, including family relationships, the following members of the Board do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and the Board has determined that each of these directors is "independent" as that term is defined under Nasdaq rules: Ross Taylor, Daniel Dickson, James Greene and Professor Zeev Weiner.

In making these determinations, the Board has considered the current and prior relationships that each non-employee director has with the Company and all other facts and circumstances that the Board deems relevant in determining their independence, including the beneficial ownership of the Company's capital stock by each non-employee director, and the transactions involving them described in the section titled "Certain Relationships and Related Transactions, and Director Independence." Other than that Drs. Katz and Dinu are married to each other, there are no family relationships among any of the directors or executive officers of the Company.
