**EBR SYSTEMS, INC.**

**Notes to the Unaudited Condensed Consolidated Financial Statements**

**Note 1 - Business and organization**

***Business overview***

EBR Systems, Inc. and subsidiaries (collectively, "EBR", "we", "our" or the "Company") is a United States based medical device company that developed the WiSE CRT System ("WiSE"), an implantable cardiac device able to provide stimulation to endocardial heart tissue for the correction of heart rhythm conditions without requiring the use of leads. This implantable device delivers left-ventricle endocardial pacing for cardiac resynchronization therapy ("CRT"), without the use of wires or leads going into the heart. On April 11, 2025, the Company received notification that the U.S. Food and Drug Administration ("FDA") has completed its review of the premarket approval application ("PMA") and approved WiSE for commercial distribution in the United States.

The Company completed its initial public offering of CHESS Depository Interests ("CDIs") and began trading on the Australian Securities Exchange ("ASX") on November 24, 2021, under the symbol "EBR".

The Company operates wholly owned foreign subsidiary entities in Australia, EBR Systems (AUST) Pty Ltd ("EBR-AU"), and the United Kingdom, EBR Systems (UK) Limited ("EBR-UK"), which establish clinical trials in Australia and the United Kingdom, respectively, and work on intellectual property development. EBR-AU was incorporated on February 23, 2017, and EBR-UK was incorporated on July 31, 2015.

***Reverse stock split***

The Company held a Special Meeting of Stockholders (the "Special Meeting") on March 11, 2026. In that Special Meeting, stockholders of the Company approved an amendment to the Company's amended and restated certificate of incorporation (the "Amendment") to effect the reverse stock split of its common stock and the transmutation ratio of CDIs to common stock at a ratio in the range of 1-for-5 to 1-for-20, with such ratio to be determined in the discretion of the Company's board of directors and with such reverse stock split to be effected at such time and date, if at all, as determined by the Company's board of directors in its sole discretion.

Pursuant to such authority granted by the Company's stockholders, the Company's board of directors approved a 1-for-10 (1:10) reverse stock split (the "Reverse Stock Split") of the Company's common stock and the filing of the Amendment to effectuate the Reverse Stock Split. The Amendment was filed with the Secretary of State of the State of Delaware and the Reverse Stock Split became effective in accordance with the terms of the Amendment at 4:00 a.m. Eastern Time on April 1, 2026 (the "Effective Time"), and the Company commenced normal trading on ASX on April 13, 2026, on a post-split basis under the existing ticker symbol "EBR". The Amendment provided that, at the Effective Time, every ten shares of the Company's issued and outstanding common stock automatically combined into one issued and outstanding share of common stock, without any change in par value per share, which remained at $0.0001. The Company's CDIs were not consolidated as part of the Reverse Stock Split, but rather the transmutation ratio of the CDIs to shares was changed from 1-to-1 to 10-to-1. See Note 10, "Common Stock" for additional information on CDIs.

The number of authorized shares of common stock remained at 600 million shares. As a result of the Reverse Stock Split, proportionate adjustments were made to the per share exercise price and/or the number of shares issuable upon the exercise or vesting of all outstanding stock options and warrants, which resulted in a proportional decrease in the number of shares of the Company's common stock reserved for issuance upon exercise or vesting of such stock options and warrants and a proportional increase in the exercise price of all such stock options and warrants. The Company does not need to recognize any additional compensation expense as a result of the adjustment to outstanding stock options.

In addition, the number of shares reserved for issuance under the Company's equity incentive plan immediately prior to the Effective Time was reduced proportionately.

No fractional shares were issued as a result of the Reverse Stock Split. Any stockholder who would have been entitled to receive a fractional share as a result of the process was entitled to the rounding up of the fractional share to the nearest whole number.

The Reverse Stock Split has been retroactively adjusted throughout these unaudited condensed consolidated financial statements for all periods presented, including exercise prices and share data. As a result of the Reverse Stock Split, the

Company reclassified approximately $41 thousand between common stock par value and additional paid-in capital.

**Note 2 - Going concern**

The accompanying unaudited condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities during the normal course of business. At each reporting period, the Company evaluates whether there are conditions or events that raise substantial doubt about its ability to continue as a going concern within one year after the date that the financial statements are issued. The Company's evaluation entails analyzing prospective operating budgets and forecasts for expectations of its cash needs and comparing those needs to the current cash, cash equivalents and marketable securities balances. The Company is required to make certain additional disclosures if it concludes substantial doubt exists and it is not alleviated by its plans or when its plans alleviate substantial doubt about its ability to continue as a going concern.

For the three months ended March 31, 2026 and 2025, the Company incurred a net loss of $17.1 million and $10.6 million, respectively. During the three months ended March 31, 2026 and 2025, the Company had negative cash flows from operations of $20.3 million and $13.6 million, respectively. As of March 31, 2026, the Company had working capital of $42.0 million and accumulated deficit of $419.3 million.

Based on the Company's cash, cash equivalents, and marketable securities as of March 31, 2026, and its expectation to generate operating losses and negative operating cash flows in the foreseeable future, as well as potential liquidity to become less than the $2.5 million required under its existing debt covenants during the next twelve months, there exists substantial doubt regarding the Company's ability to continue as a going concern for a period of at least twelve months from the date of issuance of these unaudited condensed consolidated financial statements. The Company was in compliance with its debt covenant as of March 31, 2026. Upon the occurrence of a breach of debt covenants, Runway Growth Finance Corp may, at its option, declare all obligations immediately due and payable. In an effort to alleviate these conditions, the Company will need to raise capital through the issuance of additional common stock or borrowings from financial institutions. The Company's ability to obtain additional capital in the equity capital markets is subject to several factors, including market and economic conditions, the Company's performance, and investor sentiment with respect to the Company and its industry; however, no assurance can be given as to whether additional needed financing will be available on terms acceptable to the Company, or at all. The unaudited condensed consolidated financial statements of the Company do not include any adjustments that may result from the outcome of these aforementioned uncertainties.

**Note 3 - Summary of significant accounting policies**

***Basis of presentation***

These unaudited condensed consolidated financial statements as of March 31, 2026, and for the three months ended March 31, 2026 and 2025, have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP"). Certain information and note disclosures normally included in financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to such rules and regulations. These unaudited condensed consolidated financial statements should be read in conjunction with our audited consolidated financial statements and the notes thereto for the year ended December 31, 2025.

The unaudited condensed consolidated financial statements have been prepared on the same basis as the audited consolidated financial statements. In the opinion of management, the included disclosures are adequate, and the accompanying unaudited condensed consolidated financial statements contain all adjustments which are necessary for a fair presentation of our unaudited condensed consolidated financial position as of March 31, 2026, unaudited condensed consolidated results of operations and comprehensive loss for the three months ended March 31, 2026 and 2025, and unaudited condensed consolidated cash flows for the three months ended March 31, 2026 and 2025. The unaudited condensed consolidated results of operations for the three months ended March 31, 2026, are not necessarily indicative of the consolidated results of operations that may be expected for the year ending December 31, 2026.

In the third quarter of 2025, the Company changed the presentation of Note 15, "Segment information" to better align with the information the chief operating decision maker ("CODM") uses to allocate resources and assess operating performance. Prior period segment information was updated to conform to the current period presentation. See Note 15 "Segment information" for additional disclosures.

In the fourth quarter of 2025, the Company changed its rounding presentation of these condensed consolidated financial statements to the nearest thousands, except share or per share data or as otherwise indicated. The accompanying notes to the financial statements are denominated in millions of dollars. The change in rounding presentation has been applied to all prior year amounts presented. In certain circumstances, this change adjusted previously reported balances, however, these changes were not significant, and no other changes were made to previously reported financial information. Additionally, certain columns and rows within the financial statements and tables presented may not add due to rounding. Percentages have been calculated from the underlying whole-dollar amounts for all periods presented.

***Use of estimates***

The preparation of financial statements in conformity with GAAP requires management to make estimates, judgments, and assumptions that affect the amounts reported in the unaudited condensed consolidated financial statements and accompanying notes. Significant estimates and assumptions made by management include the fair value of stock-based awards issued. Estimates are based on historical experience, where applicable and other assumptions believed to be reasonable by management. Actual results could differ materially from those estimates.

***Significant Accounting Policies***

The Company's significant accounting policies are disclosed in the 2025 Annual Report on Form 10-K. There have been no material changes to these accounting policies, except as noted below.

***Revenue Recognition***

The following table summarizes revenue from contracts with customers disaggregated by product for the three months ended March 31, 2026 and 2025 (in thousands):

---

| | | |
|:---|:---|:---|
|  | Three Months Ended March 31, | Three Months Ended March 31, |
|  | 2026 | 2025 |
| WiSE CRT System | $2320 | $- |
| Surgical tool kits | 20 |  |
| Battery replacements | 22 | - |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total revenue | $2362 | $- |

---

***Deferred revenue***

The timing of revenue recognition for WiSE CRT System and battery replacements differ from the timing of invoicing to customers. The Company invoices customers upon shipment or delivery of WiSE and battery replacements to the customer, while the revenue is recognized upon completion of the procedure. Therefore, the Company recognizes a contract liability resulting from the timing of revenue recognition and invoicing. Deferred revenue is equivalent to billings for WiSE performance obligations that are unsatisfied as of the balance sheet date. The Company expects to recognize revenue from these unfulfilled performance obligations within one year or less. The movement in the deferred revenue balance during the three ended March 31, 2026 and 2025 was as follows (in thousands):

---

| | | |
|:---|:---|:---|
|  | Three Months Ended March 31, | Three Months Ended March 31, |
|  | 2026 | 2025 |
| Balance, beginning of period | $502 | $- |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Recognition of revenue | (2342) | - |
| Balance, end of period | $1100 | $- |

***Recently adopted accounting pronouncements***

In July 2025, the FASB issued ASU 2025-05, *Financial Instruments - Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets*, which amends ASC 326-20 to provide a practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under ASC 606. The practical expedient permits all entities to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset. The amendments are effective for annual periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods. The Company adopted this ASU in the first quarter of 2026, on a prospective basis and elected the practical expedient for the calculation of current expected credit losses.

This guidance is effective for fiscal years beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, with early adoption permitted. In January 2025, the FASB issued an update 2025-01 "*Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date",* which revises the effective date of ASU 2024-03 to clarify that all public business entities are required to adopt the guidance in annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. The Company is currently evaluating the impact of this standard on its disclosures.

**Note 7 – Leases** 

The Company has an operating lease for its corporate headquarters and laboratory space, located in Sunnyvale, California, with an original lease period expiring June 30, 2024. In January 2024, the Company signed an addendum to the operating lease, extending the expiration of the lease through June 30, 2025. In March 2024, the Company signed an additional addendum to the operating lease, extending the expiration of the lease through December 31, 2025. In July 2024, the Company signed an additional addendum to the operating lease, extending the expiration of the lease through December 31, 2026. In April 2025, the Company signed an addendum to lease additional office space on a short-term basis in an adjacent office space. The Company accounted for the modification as a separate contract and will recognize associated lease payments in net loss over the lease term.

[**Table of Contents**](#toc)

In January 2025, the Company executed an operating lease for its new corporate headquarters, laboratory and manufacturing facility in Santa Clara, California. The term of the lease commenced on January 17, 2025, the date on which the landlord made the property available to the Company for the purpose of constructing leasehold improvements that will remain the property of the Company during lease term. As a result of entering into this lease agreement, the Company recorded a right-of-use asset and corresponding lease liability of $12.9 million, net of the tenant improvement allowance of $4.1 million on the commencement date. Tenant improvement allowance was fully utilized as of March 31, 2026, of which, to date, the Company received reimbursements totaling $1.5 million. The Company expects to receive additional reimbursements of $2.6 million associated with this tenant improvement allowance, which were included in accounts and other receivables on the Company's unaudited condensed consolidated balance sheets. Lease payments began in January 2026. The lease provides for a term of 132 months and includes an option to extend the lease for an additional five years, which was used in the calculation of the right of use asset and lease liability, as the Company is reasonably certain that the option will be exercised. The Company determined the probability of the exercise of a lease extension option based on its long-term strategic business outlook, significant leasehold improvements that are expected to have significant economic value to the Company, and costs relating to signing a new lease, among other factors.

Amounts reported in the unaudited condensed consolidated balance sheets for operating leases in which the Company is the lessee as of March 31, 2026 and December 31, 2025, were as follows (in thousands):

***Runway Growth Finance Corp***

On June 30, 2022, the Company entered into a loan and security agreement with Runway Growth Finance Corp. The debt is secured against substantially all assets of the Company, except for the Company's intellectual property but includes all proceeds from the sale of intellectual property. As of March 31, 2026 and December 31, 2025, the outstanding principal balance was $41.8 million and $41.8 million, respectively.

Interest on the term loan accrues on the principal amount outstanding at a floating per annum rate equal to the greater of the rate of interest noted in The Wall Street Journal Money Rates section, as the "Prime Rate" or 4.00% plus a margin of 4.9% and is payable monthly in arrears and shall be computed on the basis of a 360-day year for the actual number of days elapsed. The Company is required to make interest only payments from July 2022 to May 2027. The note payable has a maturity date of June 15, 2027, at which time any unpaid interest, outstanding principal balance, and a final payment of 4.5% of the original principal amount borrowed shall be due in full. If the Company repays the loan prior to maturity, the Company will be required to pay a prepayment fee of 0.5% of the outstanding principal balance. The Company is also required to pay a 3% success fee of the funded principal amount of the term loan at the time of a liquidity event, as defined in the loan and security agreement. The success fee is enforceable within 10 years from the execution date of the agreement.

The Company has accounted for the final payment of $1.8 million as a discount of the note that will be amortized over the life of the loan using the effective interest method. Amortization of the discount was $0.1 million and $0.1 million for the three-month period ended March 31, 2026 and 2025, respectively. This amount was recorded as additional interest expense in the accompanying unaudited condensed consolidated statements of operations. As of March 31, 2026 and December 31, 2025, the note has been shown net of unamortized discounts of $0.5 million and $0.6 million, respectively.

The Company incurred loan costs of $1.0 million, which are being amortized over the life of the loan using the effective interest method. Amortization of loan costs was $0.1 million and $0.1 million for the three-month period ended March 31, 2026 and 2025, respectively. As of March 31, 2026 and December 31, 2025, the note has been shown net of unamortized loan costs of $0.3 million and $0.3 million, respectively.

The Company is subject to customary financial and reporting covenants under the loan and security agreement. As of March 31, 2026 and December 31, 2025, the Company was in compliance with all debt covenants.

**Note 9 - Convertible preferred stock** 

As of March 31, 2026 and December 31, 2025, 10,000,000 shares of convertible preferred stock were authorized, of which no shares were issued or outstanding.

[**Table of Contents**](#toc)

**Note 10 - Common stock** 

Each share of common stock entitles the holder to one vote on all matters submitted to a vote of the Company's stockholders. Common stockholders are entitled to receive dividends, as may be declared by the Company's board of directors. As of March 31, 2026 and December 31, 2025, no dividends have been declared.

As of March 31, 2026 and December 31, 2025, 600,000,000 shares were authorized, of which 45,055,736 shares and 45,025,917 shares, respectively, were outstanding. See Note 1, "Business and organization – *Reverse stock split*" for additional information regarding the Reverse Stock Split that was effective April 1, 2026.

The Company completed its initial public offering and began trading on the ASX on November 24, 2021, under the symbol "EBR". The ASX uses a Clearing House Electronic Subregister System ("CHESS") for the clearance and settlement of trades on the ASX. The State of Delaware does not recognize the CHESS system of holding securities or electronic transfers of legal title to shares. To enable companies to have their securities cleared and settled electronically through CHESS, CDIs are issued. CDIs are units of beneficial ownership in shares and are traded in a manner similar to shares of Australian companies listed on the ASX. The legal title to the shares are held by a depository, CHESS Depositary Nominees ("CDN'), which is a wholly owned subsidiary of the ASX, and is an approved general participant of ASX Settlement.

Additionally, the Company has reserved the following shares of common stock for issuance as of March 31, 2026:

---

| | |
|:---|:---|
| Common stock warrants | 1947853 |
| 2013 Equity Incentive Plan | 1611890 |
| 2021 Equity Incentive Plan | 3673015 |
| Outside of 2021 Equity Incentive Plan | 89758 |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Total shares of common stock reserved for issuance | 7322516 |

**Note 11 - Stock-based compensation**

The Company and its stockholders adopted the 2013 Equity Incentive Plan (the "2013 Plan") June 18, 2013, which reserved shares of the Company's common stock for the granting of incentive and nonqualified stock options to employees, directors, and consultants. On October 14, 2021, the Company replaced the 2013 Plan with the 2021 Equity Incentive Plan (the "2021 Plan") in connection with its initial public offering. Under the 2021 Plan, 3,673,015 shares of common stock are reserved. The Company may grant options to purchase common stock, stock appreciation rights, restricted stock awards and other forms of stock-based compensation. Stock options generally vest over four years and expire no later than 10 years from the date of grant. The Board of Directors has the authority to select the employees to whom options are granted and determine the terms of each option, including: i) the number of shares of common stock subject to the option; ii) when the option becomes exercisable; iii) the option exercise price, which must be at least 100% of the fair market value of the common stock as of the date of grant; and iv) the duration of the option, which may not exceed 10 years.

As of March 31, 2026, options to purchase a total of 3,100,009 shares of common stock remained outstanding and 573,006 shares remain available for grant under the 2021 Plan and 89,758 remained outstanding outside of the 2021 Plan. As of March 31, 2026, options to purchase a total of 1,611,890 shares of common stock remained outstanding under the 2013 Plan. As of March 31, 2026, no shares of common stock remain available for grant under the 2013 Plan.

Stock option activity for the three-month period ended March 31, 2026, was as follows:

---

| | | | |
|:---|:---|:---|:---|
|  | Shares | Weighted-<br> Average <br> Exercise <br> Price | Weighted-<br> Average <br> Remaining <br> Contractual <br> Life (in years) |

| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Granted | 64400 | 5.13 |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Cancelled | (44931) | 6.37 |  |
| &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Exercised | (28573) | 4.62 |  |
| Outstanding as of March 31, 2026 | 4801657 | $4.91 | 6.54 |
| Vested and expected to vest as of March 31, 2026 | 4801657 | $4.91 | 6.54 |
| Exercisable as of March 31, 2026 | 3225978 | $3.83 | 5.48 |

[**Table of Contents**](#toc)

The fair value of the options granted to employees is estimated on the grant date using the Black-Scholes option valuation model. This valuation model for stock-based compensation expense requires the Company to make assumptions and judgments about the variables used in the calculation, including the expected term (weighted-average period of time that the options granted are expected to be outstanding), the volatility of the Company's common stock, an assumed risk-free interest rate and expected dividends. The Company uses the simplified calculation of expected life and volatility is derived from the combination of the average historical stock volatilities of several publicly traded companies with characteristics similar to those of the Company, and on the Company's stock price, as quoted on the ASX. The risk-free rate is based on the U.S. Treasury yield curve in effect at the time of grant for periods corresponding with the expected life of the option. The Company uses the straight-line method for expense attribution. The weighted-average grant-date fair values of stock options granted during the three months ended March 31, 2026 and 2025, was $3.23 per share and $6.38 per share, respectively.

The following assumptions were used to calculate the grant-date fair value of employee stock options granted during the three months ended March 31, 2026 and 2025:

---

| | | |
|:---|:---|:---|
|  | Three Months Ended March 31, | Three Months Ended March 31, |
|  | 2026 | 2025 |
| Expected term (in years) | 6.08 | 5.53 – 6.08 |
| Expected volatility | 65.31% - 65.50% | 65.27% - 65.73% |
| Expected dividend yield | 0.00% | 0.00% |
| Risk-free interest rate | 3.72% - 4.11% | 4.09% - 4.47% |

As of March 31, 2026, the weighted-average exercise price of outstanding warrants was $5.64, with a weighted-average remaining contractual life of 4.09 years.

[**Table of Contents**](#toc)

**Note 13 - Income taxes**

During the three months ended March 31, 2026 and 2025, the Company does not have an income tax benefit or expense. The Company has historically incurred net operating losses and maintains a full valuation allowance against its net deferred tax assets. Valuation allowances are recorded when the expected realization of the deferred tax assets does not meet a "more likely than not" criterion. Realization of the Company's deferred tax assets are dependent upon the generation of future taxable income, the amount and timing of which are uncertain.

The Company's effective tax rate was 0% for the three months ended March 31, 2026 and 2025. The difference between the effective tax rate and the federal statutory rate of 21% was primarily due to the full valuation allowance recorded on the Company's net deferred tax assets, state and foreign tax benefits, research and development tax credits, and other non-deductible expenses.

During the three-month period ended March 31, 2026, there were no material changes to the Company's uncertain tax positions.

The One Big Beautiful Bill Act ("OBBA") includes significant U.S. tax provisions, including the permanent extension of certain expiring provisions of the Tax Cuts and Jobs Act, modifications to the international tax framework, and the restoration of favorable tax treatment for certain business provisions. The legislation has multiple effective dates from 2025 through 2027. The Company continues to monitor any new tax laws and notes those effective in 2026 do not have a material impact on the Company's unaudited condensed consolidated financial statements for the three months ended March 31, 2026.

**Note 15 - Segment information**

The Company's chief operating decision maker ("CODM") is the Chief Executive Officer. The Company has determined that it has a single operating and reportable segment. The CODM uses revenue, gross margin and operating expenses at the consolidated level to allocate resources, monitor budget versus actual results, and manage operations. Significant expenses within operating expenses include engineering and development, clinical and regulatory, sales and marketing, and general and administrative expenses at the consolidated level.

Substantially all of the segment revenue is derived from sales to customers in the U.S. Revenue by geography is based on billing address of the customer. International revenue accounted for less than 5% of the total revenue during the periods presented. Long-lived assets held outside the U.S. are immaterial.

**Note 16 - Commitments and contingencies**

***Purchase commitments***

The Company purchases raw materials, manufacturing equipment, and various services from a variety of vendors. During the normal course of business, in order to manage manufacturing lead times and help ensure an adequate supply of certain items, we enter into agreements with suppliers that either allow us to procure goods and services when we choose or that establish purchase requirements over the term of the agreement. In certain instances, our purchase agreements allow us to cancel, reschedule, or adjust our purchase requirements based on our business needs prior to firm orders being placed. Consequently, only a portion of our purchase commitments are firm and non-cancelable. As of March 31, 2026, the Company's obligations under such arrangements were approximately $14.0 million.

***Cybersecurity***

The Company detected a cybersecurity incident in which an unauthorized third party gained access to certain information systems of the Company on or around February 13, 2026. Upon detection, the Company promptly initiated response protocols and began taking steps to contain, assess and remediate the cybersecurity incident, including launching an investigation with external cybersecurity experts. Although the Company believes that the cybersecurity incident has not had a material impact on its overall financial condition or results of operations, its evaluation and response to this incident are ongoing and the Company may discover other impacts or new events related to this incident may occur that could affect the Company's financial condition or results of operations. As of March 31, 2026, incurred cybersecurity expenses limited to the Company's insurance deductibles have been recorded and reflected within the Company's unaudited condensed consolidated financial statements and such amounts are not material.

***Contingencies***

The Company is party to various legal proceedings from time to time. A liability is accrued when a loss is both probable and can be reasonably estimated. Management believes that the probability of a material loss with respect to any currently pending legal proceeding is remote. However, litigation is inherently uncertain, and it is not possible to definitively predict the ultimate disposition of any of these proceedings. The Company does not believe that there are any pending legal proceedings or other loss contingencies that will, either individually or in the aggregate, have a material adverse impact on the Company's unaudited condensed consolidated financial statements.

**Note 17 – Subsequent events**

See Note 1 – Business and organization – *"Reverse stock split"*

On May 6, 2026, stockholders approved the addition of 1,801,036 shares of common stock, as adjusted for the Reverse Stock Split, to the number of shares of common stock reserved for issuance under the 2021 Plan, by operation of the "evergreen" provision set forth in the 2021 Plan.

**ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS**

*The following discussion and analysis of our financial condition and results of operations should be read in conjunction with our unaudited condensed consolidated financial statements and related notes and other information included elsewhere in this Quarterly Report on Form 10-Q and the audited consolidated financial statements and notes thereto and management's discussion and analysis of financial condition and results of operations for the year ended December 31, 2025. In addition to historical data, this discussion contains forward-looking statements about our business, ability to continue as a going concern, ability to successfully commercialize our WiSE CRT System, results of operations, cash flows, financial condition and prospects based on current expectations that involve risks, uncertainties, assumptions, and other important factors. Our actual results could differ materially from such forward-looking statements. Factors that could cause or contribute to those differences include, but are not limited to, those identified below and those discussed in Part I, Item 1A. Risk Factors of our Annual Report on Form 10-K. Additionally, our historical results are not necessarily indicative of the results that may be expected for any period in the future. We use words such as "anticipate," "believe," "continue," "could," "estimate," "expect," "intend," "may," "plan," "predict," "project," "potential," "seek," "should," "will," "would," and similar expressions to identify forward-looking statements.*

**Overview**

EBR is a U.S. based medical device company that developed the WiSE CRT System ("WiSE"), an implantable cardiac pacing system able to provide stimulation to endocardial heart tissue for the correction of heart rhythm conditions without requiring the use of leads. That implantable device is part of a cardiac resynchronization therapy ("CRT"), offering endocardial heart tissue stimulation without the complications associated with traditional lead-based systems. Cardiac rhythm management ("CRM") systems use leads to conduct electricity from an implantable pulse generator ("IPG") to electrodes that deliver therapeutic electric pulses to heart tissue. While leads are a critical part of most CRM systems, they have long been recognized as a primary shortcoming of these systems and are a leading cause of device failure.

We initially developed WiSE for use in conjunction with another implanted pacemaker to provide CRT to patients who are unable to receive CRT from a traditional lead-based system or are at high risk of complications from an upgrade procedure. WiSE CRT technology is engineered to benefit patients who have not seen success with conventional CRT or face high complication risks. By eliminating lead requirements for left ventricular pacing, WiSE CRT introduces a novel approach to cardiac pacing, with the potential to transform CRT delivery.

On April 11, 2025, we received notification that the Center for Devices and Radiological Health ("CDRH") of the Food and Drug Administration ("FDA") had completed its review of our premarket approval application ("PMA") for WiSE and approved WiSE for commercial distribution in the U.S. for adult patients who are at least 22 years of age, are indicated for CRT, have an existing or are eligible for an implanted right ventricular pacing system, and are in one of the following two categories: 1) patients in whom previous coronary sinus ("CS") lead implantation was unsuccessful, or where an implanted lead has been turned off, referred to as "previously untreatable"; or 2) patients with previously implanted pacemakers or Implantable Cardioverter-Defibrillators ("ICDs") in whom standard CRT upgrade is not advisable due to known relative contraindications for CS lead or CRT device implantation, referred to as "high risk upgrades".

We have launched WiSE with the focus on driving adoption of WiSE at key, high-volume, hospitals or medical facilities within the U.S. to be followed by select, high-volume hospitals or medical facilities in markets outside the U.S. ("OUS") that we would target after evaluating regulatory and reimbursement considerations. The growth of our business depends on our ability to successfully commercialize WiSE and gain wide acceptance of WiSE by continuing to make physicians and other hospital staff aware of the benefits of WiSE to generate increased demand and frequency of use and thus increase sales to our hospital customers. Our ability to grow our business will also depend on our ability to expand our customer base in existing or new target markets. The rate at which we grow our sales force and the speed at which newly hired salespeople become effective can impact our revenue growth or our costs incurred in anticipation of such growth. We intend to make significant investments in our sales and marketing organization by increasing the number of U.S. sales representatives and expanding our international marketing programs to help facilitate further adoption among existing hospital accounts as well as broaden awareness of our products to new hospital accounts.

[**Table of Contents**](#toc)

**Financial overview**

Our WiSE CRT System received approval from the FDA for commercial distribution in April 2025, and we began commercializing WiSE during the second quarter of 2025. During the three months ended March 31, 2026, we had 41 commercial implants at 19 hospitals in the US, and recognized revenue of $2.4 million. An additional 22 physicians were trained to implant the WiSE CRT System, and 16 additional purchase agreements were signed with target LMR sites during the three months ended March 31, 2026. The commercial potential of and our ability to successfully commercialize WiSE is unproven and will require, among other things, effective sales, marketing, manufacturing, distribution, information systems and pricing strategies, as well as compliance with applicable laws and regulations.

Since inception, we have incurred significant net losses and expect to continue to incur net losses until we are able to generate sufficient revenue. Since our inception, our operations have been financed primarily by net proceeds from the sale of our CDIs, common stock, convertible preferred stock, and indebtedness. As of March 31, 2026, we had $30.9 million in cash, cash equivalents, and marketable securities and an accumulated deficit of $419.3 million. For a more comprehensive discussion see "Liquidity and Capital Resources" and "Future Funding Requirements" below.

**Factors Affecting Our Business**

There are a number of factors that have impacted, and we believe will continue to impact, our results of operations and growth. These factors include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·  ***Regulatory approvals/clearances.*** Our business strategy depends on the successful FDA submission
of our PAS and ongoing annual reporting of our WiSE CRT System to the FDA.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·  ***Market acceptance*** . The growth of our business depends on our ability to successfully commercialize
WiSE and gain wide acceptance of WiSE by continuing to make physicians and other hospital staff aware of the benefits of WiSE to generate
increased demand and frequency of use and thus increase sales to our hospital customers. Our ability to grow our business will also depend
on our ability to expand our customer base in existing or new target markets.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·  ***Sales force size and effectiveness*** . The rate at which we grow our sales force and the speed
at which newly hired salespeople become effective can impact our revenue growth or our costs incurred in anticipation of such growth.
We intend to make significant investments in our sales and marketing organization by increasing the number of U.S. sales representatives
and expanding our international marketing programs to help facilitate further adoption among existing hospital accounts as well as broaden
awareness of our products to new hospital accounts.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·  ***Competition*** . Our industry is intensely competitive and, in particular, we compete with a
number of large, well-capitalized companies on multiple fronts. We must strive to be successful in light of our competitors' existing
and future products and related pricing and their resources to successfully market to the physicians who use our products.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;·  ***Clinical results*** . Publications of clinical results by us, our competitors and other third
parties can have a significant influence on whether, and the degree to which, our products are used by physicians and the procedures and
treatments those physicians choose to administer for a given condition.

While these factors may present significant opportunities for us, they also pose significant risks and challenges that we must address.

**Components of our Consolidated Results of Operations**

***Revenue***

We derive most of our revenue from sales of WiSE to the hospital facilities that implant our WiSE CRT System. We recognize revenue upon the transfer of goods or services to a customer at an amount that reflects the expected consideration to be received in exchange for those goods or services. Specifically, revenue from the sale of WiSE is recognized at an amount that reflects the expected consideration upon notice that our products have been used in a surgical procedure. Our revenue fluctuates primarily based on the volume of procedures performed. Our revenue is expected to continue to fluctuate in the future from quarter-to-quarter due to a variety of factors, including the success of our sales force in expanding adoption of WiSE in new hospitals and the number of physicians who are aware of and implant WiSE.

[**Table of Contents**](#toc)

Nearly all our revenue results from sales in the United States, but we also have limited sales of replacement batteries for our WiSE CRT System to hospital facilities with patients who have been or are currently enrolled in our clinical study in the United Kingdom ("UK").

***Cost of Goods Sold and Gross Margin***

Cost of goods sold consists primarily of costs related to materials, components and subassemblies, personnel-related expenses for our manufacturing and quality assurance employees, manufacturing overhead and charges for excess, obsolete and non-sellable inventories. Overhead costs include the cost of quality assurance, testing, material procurement, inventory control, operations supervision and management personnel, an allocation of facilities and information technology expenses, including rent and utilities, and equipment depreciation. Cost of goods sold also includes certain indirect costs such as those incurred for shipping our WiSE CRT System. We record adjustments to our inventory valuation for estimated excess, obsolete and non-sellable inventories based on assumptions about future demand, past usage, changes to manufacturing processes and overall market conditions.

We calculate gross margin as gross profit divided by revenue. Our gross margin has been and will continue to be affected by a variety of factors, primarily by our manufacturing costs, pricing, and the use of inventory that was previously expensed during our clinical trial. Our gross margin is expected to decrease over the near term as we continue to utilize inventory that was previously expensed as research and development costs, but over the long term our gross margin may increase to the extent our production volume increases as our fixed manufacturing costs would be spread over a larger number of units, thereby reducing our per-unit manufacturing costs. We expect our gross margin will fluctuate from period to period based upon the factors described above.

***Operating Expenses***

 

*Research and Development Expenses*

Research and development expenses primarily consist of personnel-related expenses, including salaries, bonuses, fringe benefits and other compensation-related costs, including stock-based compensation expense, for employees engaged in research and development functions. Research and development expenses also include costs of conducting our post-approval study, such as expenses associated with our clinical research organization, or CRO, who provided project management, outside service fees paid to third party consultants and contractors related to WiSE engineering, quality assurance and regulatory approval, as well as contract manufacturing of WiSE and allocated facility costs.

We expense research and development costs as incurred. Non-refundable advance payments that we make for goods or services to be received in the future for use in research and development activities are recorded as prepaid expenses and other long-term assets, which are expensed as the related goods are delivered or the services are performed, or when it is no longer expected that the goods will be delivered, or the services rendered.

We anticipate that our research and development expenses will increase significantly in the future as we:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· hire and retain additional personnel, including research, clinical, development, manufacturing, quality
control, quality assurance and regulatory personnel;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· conduct our post-approval study;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· continue to advance the research and development of our WiSE CRT system or other product candidates; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· develop and validate our commercial-scale current good manufacturing practice ("cGMP").

*Selling, General and Administrative Expenses*

 

Selling, general and administrative expenses primarily consist of personnel-related costs, including salaries, bonuses, fringe benefits and other compensation-related costs, including stock-based compensation expense, for our personnel and external contractors involved in our sales and marketing, executive, finance, legal and other administrative functions. Selling, general and administrative expenses also include costs incurred for outside services associated with such functions, including costs associated with obtaining and maintaining our patent portfolio and professional fees for accounting, auditing, tax, legal services, and other consulting expenses.

[**Table of Contents**](#toc)

We anticipate that our selling, general and administrative expenses will increase significantly in the future as we:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· hire and retain additional sales, general and administrative personnel to support the expected growth
in our sales and marketing activities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· continue to expand our sales, marketing and administrative function to support the sales adoption of WiSE;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· maintain, expand, and protect our intellectual property portfolio; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· incur increased expenses associated with operating as a U.S. publicly reporting company, including increased
costs of accounting, audit, legal, regulatory, and tax-related services, and director and officer insurance premiums.

 

***Interest expense***

Interest expense primarily consists of cash and non-cash interest related to our notes payable. See "Loan and Security Agreements" section below for more details about our debt agreements.

***Interest income***

Interest income consists of interest income, including accretion of discounts, generated from our cash, cash equivalent, and marketable securities.

***Gain/ (loss) on foreign currency***

 

Gains and losses arising from the settlement and remeasurement of monetary assets and liabilities denominated in currencies other than a subsidiary's functional currency.

**Critical Accounting Estimates**

Our critical accounting estimates are more fully described in our Annual Report on Form 10-K for the year ended December 31, 2025. There have been no significant changes to our critical accounting estimates since December 31, 2025.

**Recent Accounting Pronouncements**

See the sections titled "Recently adopted accounting pronouncements" and "Recently issued accounting pronouncements not yet adopted" in Note 3 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

**Non- GAAP Financial Measures**

Adjusted earnings before interest, income taxes, depreciation and amortization ("Adjusted EBITDA"), a non-GAAP measure used by management to assess operating performance, is defined as net loss, excluding interest expense, net, depreciation and amortization, and stock-based compensation. Adjusted EBITDA is intended as a supplemental measure of our performance and provides useful information to management and investors regarding our operating results.

We present Adjusted EBITDA in this filing because we believe it assists investors and analysts in comparing our operating performance across reporting periods on a consistent basis by excluding items that we do not believe are indicative of our ongoing operating performance. Period-to-period comparison of Adjusted EBITDA helps our management identify additional trends in our company's financial results that may not be shown solely by period-to-period comparison of net loss. In addition, we believe that providing Adjusted EBITDA, together with a reconciliation of Adjusted EBITDA to net loss, helps investors make comparisons between our company and other companies that may have different capital structures, different capitalized asset values, different forms of employee compensation and different strategic nonrecurring projects. Adjusted EBITDA has its limitations as an analytical tool because of the excluded items, and you should not consider it in isolation or as a substitute for analysis of our results as reported under U.S. GAAP. Some of these limitations include:

[**Table of Contents**](#toc)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Adjusted EBITDA does not reflect interest expense and interest income because these items are not directly
attributable to the performance of our business operations and may vary over time due to financing transactions that we have entered into
or may enter into in the future.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Adjusted EBITDA does not reflect certain non-cash items, including depreciation and amortization, and
stock-based compensation expense. We believe that excluding the effect of these expenses from Adjusted EBITDA assists management and investors
in making period-to-period comparisons in our company's operating performance because the amount of such expenses in any specific
period may not directly correlate to the underlying performance of our business operations.

A reconciliation between net loss and adjusted EBITDA is presented below:

**Results of Operations**

***Comparison of the Three Months Ended March 31, 2026, to the Three Months Ended March 31, 2025***

 **

We recorded a net loss of $17.1 million in the three-month period ended March 31, 2026, an increase of $6.5 million, or 61.8%, from the three-month period ended March 31, 2025. The increased loss in 2026 was due to an increase in selling, general and administrative expenses, and research and development expenses, as discussed below. Other (expense), net also increased in 2026, primarily due to a decrease in interest income, as discussed below.

The following table summarizes our operating results for the three months ended March 31, 2026 and 2025:

*Revenue and Cost of Goods Sold*

 

Revenue and cost of goods sold was $2.4 million and $2.2 million, respectively, during the three-month period ended March 31, 2026, resulting from the Company completing commercial implants at nineteen hospitals in the US. There was no revenue or cost of goods sold during the three-month period ended March 31, 2025, resulting from the FDA approval of our WiSE CRT System in April 2025.

 

*Gross Profit, and Gross Margin*

Gross profit increased to $0.2 million, or 100% during the three-month period ended March 31, 2026, as compared to the three-month period ended March 31, 2025, resulting from the FDA approval of our WiSE CRT System in April 2025. Gross margin was 7.8% for the three-month period ended March 31, 2026. Our gross margin was positively affected and will continue to be affected in the near future by the use of inventory that was previously expensed during our clinical trial. Excluding the use of previously expensed inventory, we would have had a negative gross margin of 25.4%.

 

***Operating Expenses***

 

*Research and Development*

| Total research and development expense | $6417 | $5419 | $998 | 18.4% |

---

Research and development expenses increased by $1.0 million, or 18.4% during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. The increase was primarily due to a $0.4 million increase in contract manufacturing, materials and components as a result of higher expenses related to research and development projects. Clinical expenses increased by $0.2 million as a result of higher expenses related to WiSE CRT post-approval study. Facility-related expenses increased by $0.3 million in support of our continuing expansion of research and development activities.

[**Table of Contents**](#toc)

*Selling, General and Administrative Expenses*

Selling, general and administrative expenses increased by $5.6 million, or 127.8%, during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. Personnel-related expenses including salaries, bonuses, stock-based compensation and certain fringe benefits increased by $2.8 million as a result of the expansion of our workforce to support increased adoption of our WiSE CRT System. Travel-related expenses increased by $1.7 million due to increased travel to support our sales and marketing efforts. Professional fees increased by $0.4 million, primarily resulting from higher accounting and legal services fees. Facility-related and other expenses increased by $0.4 million, primarily resulting from the higher rent and common area maintenance costs for our new corporate headquarters and manufacturing facility. Corporate expenses increased by $0.2 million, primarily resulting from the higher expenses related to investor relations, and computer software licenses.

*Other (expense) income, net*

Other (expense) income, net increased by $0.2 million during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. This increase primarily resulted from a $0.2 million decrease in interest income earned on investments in marketable securities, including the accretion of discounts on marketable securities.

**Liquidity and Capital Resources**

We manage our cash and capital structure to maximize shareholder return, maintain its financial condition and maintain flexibility for future strategic initiatives. We continuously assess our working capital needs, debt and leverage levels, debt maturity schedule, capital expenditure requirements and future investments. As of March 31, 2026 and December 31, 2025, we had approximately $30.9 million and $54.2 million, respectively, in cash, cash equivalents, and marketable securities. Based on our cash, cash equivalents, and marketable securities as of March 31, 2026, and our expectation to generate operating losses and negative operating cash flows in the foreseeable future, there exists substantial doubt regarding our ability to continue as a going concern for a period of at least twelve months from the date of this Form 10-Q.

*Going concern consideration*

 

The accompanying unaudited condensed consolidated financial statements have been prepared on a going concern basis, which contemplates the realization of assets and the satisfaction of liabilities during the normal course of business. For the three months ended March 31, 2026 and 2025, we incurred a net loss of $17.1 million and $10.6 million, respectively. During the three months ended March 31, 2026 and 2025, we had negative cash flows from operations of $20.3 million and $13.6 million, respectively. As of March 31, 2026, we had working capital of $42.0 million and accumulated deficit of $419.3 million. These factors raise substantial doubt about our ability to continue as a going concern. Until we are able to generate consistent and sufficient revenue from sales of our WiSE CRT System, our ability to continue as a going concern is dependent on our ability to raise additional capital through the issuance of additional common stock or borrowings from financial institutions. Our ability to obtain additional capital in the equity capital markets is subject to several factors, including market and economic conditions, our performance, and investor sentiment with respect to our company and our industry.

**Loan and Security Agreements**

On June 30, 2022, we entered into a loan and security agreement with Runway Growth Finance Corp. The debt is secured against substantially all of our assets, except for intellectual property, but includes all proceeds from the sale of intellectual property. The loan agreement provides three term loan tranches. We received the initial draw of $20.0 million in June 2022. We received positive interim analysis data, sufficient to proceed with the clinical trial and premarket approval submission to the U.S. Food and Drug Administration, which allowed us to draw the second tranche of $20.0 million in June 2023. The final tranche provided $10.0 million from the date of approval from the FDA for the WiSE CRT System and ended on June 30, 2024. We did not receive FDA approval by June 30, 2024, and therefore did not meet the draw requirements of the third and final tranche.

[**Table of Contents**](#toc)

Interest on the term loan accrues on the principal amount outstanding at a floating per annum rate equal to the greater of the rate of interest noted in The Wall Street Journal Money Rates section, as the "Prime Rate" or 4.00% plus a margin of 4.9% and is payable monthly in arrears and shall be computed on the basis of a 360-day year for the actual number of days elapsed. We are required to make interest only payments from July 2022 to May 2027. The note payable has a maturity date of June 15, 2027, at which time any unpaid interest, outstanding principal balance, and a final payment of 4.5% of the original principal amount borrowed shall be due in full. If we repay the loan prior to maturity, we will be required to pay a prepayment fee of 0.5% of the outstanding principal balance. We are also required to pay a 3% success fee of the funded principal amount of the term loan at the time of a liquidity event, as defined in the loan and security agreement. The success fee is enforceable within 10 years from the execution date of the agreement.

As of March 31, 2026 and December 31, 2025, the outstanding principal balance was $41.8 million, which included the principal borrowings under tranche one and tranche two, as well as the final payment of 4.5% of the principal borrowings to date.

We are subject to customary financial and reporting covenants under the loan and security agreement. As of March 31, 2026 and December 31, 2025, we were in compliance with all debt covenants.

**Future Funding Requirements**

Despite recent FDA approval of WiSE CRT System, the outcome of any clinical activities and/or regulatory approval process is highly uncertain, we cannot reasonably estimate whether our future development activities may succeed; or whether we will be able to effectively commercialize WiSE CRT System in the U.S., if at all. We may never recoup our investment in any WiSE CRT System development which would adversely affect our financial condition and our business and business prospects. In addition, our plans and timing expectations could be further delayed or interrupted by the effects of macroeconomic or other global conditions, including those resulting from inflation, rising interest rates, prospects of a recession, bank failures and other disruptions to financial systems, civil or political unrest, military conflicts, pandemics or other health crises and supply chain and resource issues.

To date, we have not generated significant commercial product revenue. We will continue to require additional capital to successfully commercialize WiSE CRT System and fund operations for the foreseeable future. Our primary uses of cash are to fund our operations, which consist primarily of research and development expenses, manufacturing automation and scaleup, and selling, general and administrative expenses. We expect our expenses to continue to increase in connection with our ongoing activities as we continue to commercialize WiSE CRT System.

We may seek to raise capital through equity offerings or debt financings, collaboration agreements, or other arrangements with other companies, or through other sources of financing. Adequate additional funding may not be available to us on acceptable terms or at all. Our failure to raise capital as and when needed could have a negative impact on our consolidated financial condition and our ability to pursue our business strategies. We anticipate that we will need to raise substantial additional capital, the requirements of which will depend on many factors, including:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the degree of success we experience in commercializing our WiSE CRT System;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the cost, timing and results of our post-marketing trial and regulatory reviews;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the cost of our research and development activities for new and modified products;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the cost and timing of growing our sales, marketing and distribution capabilities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the terms and timing of any collaborative, licensing and other arrangements that
we may establish, including any contract manufacturing arrangements;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the timing, receipt and amount of sales from our WiSE CRT System;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the emergence of competing or complementary technologies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the impact of global business, political and macroeconomic conditions, including
inflation, rising interest rates, uncertainty with respect to the federal budget, instability in the global banking system, volatile market
conditions, supply chain disruptions, cybersecurity events, and global events, including regional conflicts around the world;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the cost of preparing, filing, prosecuting, maintaining, defending and enforcing
any patent claims and other intellectual property rights; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· the extent to which we acquire or invest in businesses, products or technologies,
although we currently have no commitments or agreements relating to any of these types of transactions.

[**Table of Contents**](#toc)

If we raise additional capital through debt financing, we may be subject to covenants that restrict our operations including limitations on our ability to incur liens or additional debt, pay dividends, make certain investments, and engage in certain merger, consolidation, or asset sale transactions. Any debt financing or additional equity that we raise may contain terms that are not favorable to us. If we raise funds through collaborations, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs, product candidates 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 terminate some or all of our development programs and clinical trials or delay investments in our manufacturing scale-up and automation. In addition, our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and the recent disruptions to and volatility in the credit and financial markets. Furthermore, this Quarterly Report on Form 10-Q contains statements expressing substantial doubt about our ability to continue as a going concern. If we seek additional financing to fund our business activities in the future and there remains substantial doubt about our ability to continue as a going concern, investors or other financing sources may be unwilling to provide funding to us on commercially reasonable terms, if at all.

**Contractual Obligations and Commitments**

As of March 31, 2026, we had $0.4 million in operating lease obligations for our corporate headquarters and laboratory space located in Sunnyvale, California. Additionally, in January 2025, we entered into a new lease agreement for our new corporate headquarters, laboratory and manufacturing facility in Santa Clara, California, for which we had recorded $18.1 million in operating lease obligations as of March 31, 2026.

As of March 31, 2026, the outstanding principal balance under our loan and security agreement described above was $41.8 million, which included the principal borrowings under tranche one and tranche two, as well as the final payment of 4.5% of the principal borrowings to date.

In addition, we have agreements with suppliers and other parties to purchase inventory. Product inventory obligations consist primarily of purchase order commitments for raw materials and sub-assemblies used in the production of the WiSE CRT System. In certain instances, our purchase agreements allow us to cancel, reschedule, or adjust our purchase requirements based on our business needs prior to firm orders being placed. As of March 31, 2026, our obligations under such arrangements were approximately $14.0 million.

**Working Capital**

*March 31, 2026, Compared to December 31, 2025*

As of March 31, 2026, we had working capital of $42.0 million, comprised of current assets of $54.0 million and current liabilities of $12.0 million. Current assets, consisting of cash and cash equivalents, marketable securities, accounts and other receivables, inventory, prepaid expenses, and other current assets, decreased by $19.1 million as of March 31, 2026, compared to December 31, 2025. The capitalization of inventory resulted in a $1.7 million increase in working capital. An increase in accounts and other receivables, primarily due to the amounts outstanding from customers from sales of Company's product, as well as the reimbursements for leasehold improvements, resulted in a $2.8 million increase in working capital as of March 31, 2026. Additionally, an increase in other current assets, primarily due to an increase in deferred costs of goods sold, which was offset by a decrease in deposits to vendors for the purchases of machinery and equipment for the new manufacturing facility, resulted in a $0.2 million increase in working capital as of March 31, 2026. These increases in current assets were offset by $0.5 million decrease in prepaid expenses, and a $23.3 million decrease in cash, cash equivalents and marketable securities which were used to support our working capital and capital expenditure requirements.

Current liabilities, consisting primarily of accounts payable, accrued liabilities, lease obligations, and interest payable, decreased by approximately $2.0 million as of March 31, 2026, compared to December 31, 2025. The decrease primarily resulted from a $1.3 million decrease in accounts payable, which was mainly due to the activity related to construction of leasehold improvements at the new corporate headquarters, as well as the purchases of raw materials. Accrued expenses decreased by approximately $0.6 million as of March 31, 2026, compared to December 31, 2025. The decrease primarily resulted from the payout of annual bonuses, which was partially offset by an increase in deferred revenue from sales of our WiSE CRT System. Additionally, operating lease liabilities decreased by approximately $0.1 million, which contributed to the overall decrease in current liabilities.

**Cash Flows**

*March 31, 2026, Compared to March 31, 2025*

 

The following table summarizes our cash flows for the three months ended March 31, 2026 and 2025:

***Operating Activities***

 

Net cash used in operating activities during the three months ended March 31, 2026, was $20.3 million, compared to $13.6 million during the three months ended March 31, 2025, representing an increase in use of $6.7 million. This increase is primarily attributed to an increase in net loss of $6.5 million, a decrease in cash from changes in working capital of $0.8 million, which were partially offset by an increase in non-cash adjustments of $0.6 million.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The increase in net loss of $6.5 million primarily resulted from increases in personnel costs, increases
in professional fees, and decrease in interest income, as further described under "Results of Operations" above.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Non-cash items primarily consisted of decrease in accretion of discount on marketable securities of $0.1
million driven by fluctuating interest rates and maturity term, a $0.4 million increases in stock-based compensation due to new options
issuance to new hires and existing employees, and a $0.1 million increase in the adjustment to lease amortization.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· The decrease in changes from working capital activities primarily consisted of $2.5 million decrease in
cash provided from accounts and other receivables primarily due to the timing of collections on reimbursable leasehold improvements and
outstanding invoices from customers, a $0.4 million increase in cash used for deposits to vendors, and a $0.2 million increase in cash
used from accounts payable and accrued expenses due to the timing of invoice payments. These decreases were partially offset by of $1.3
million decrease in use of cash for inventory purchases, and a $0.5 million decrease in use of cash for prepayments, and a $0.5 million
increase in cash from the operating lease liability.

***Investing Activities***

 

Net cash provided by investing activities during the three months ended March 31, 2026, was $20.9 million, compared to $17.9 million during the three months ended March 31, 2025, representing an increase in cash provided of $3.0 million. The increase was attributable to a $6.2 million increase in cash from the maturities and sales of marketable securities during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025. This change was partially offset by a $3.2 million increase in purchase of property and equipment during the three months ended March 31, 2026, as compared to the three months ended March 31, 2025.

***Financing Activities***

 

Net cash provided by financing activities during the three months ended March 31, 2026, was $0.1 million, compared to $0.2 million during the three months ended March 31, 2025, representing a decrease in cash provided of $0.1 million, which was primarily attributable to the proceeds from exercise of stock options.

**ITEM 4: CONTROLS AND PROCEDURES**

***Evaluation of Disclosure Controls and Procedures***

 ****

Under the supervision and with the participation of our management, including our Chief Executive Officer and Chief Financial Officer, we evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(e) and 15(d)-15(e) under the Exchange Act as of the end of the period covered by this Quarterly Report on Form 10-Q. Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including the Chief Executive Officer and the Chief Financial Officer, to allow timely decisions regarding required disclosures. Any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objective and management necessarily applies its judgement in evaluating the cost-benefit relationship of possible controls and procedures. Based on that evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were effective at a reasonable assurance level as of March 31, 2026.

***Changes in Internal Control over Financial Reporting***

There have been no changes in our internal control over financial reporting, as such term is defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act, during the three months ended March 31, 2026, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

***Limitations on Effectiveness of Controls and Procedures***

 ****

In designing and evaluating disclosure controls and procedures, our management recognizes that any system of controls, however well designed and operated, can provide only reasonable assurance, and not absolute assurance, that the desired control objectives of the system are met. In addition, the design of any control system is based in part upon certain assumptions about the likelihood of future events. Because of these and other inherent limitations of control systems, there can be no assurance that any design will succeed in achieving its stated goals in all future circumstances. Accordingly, our disclosure controls and procedures are designed to provide reasonable, not absolute, assurance that the objectives of our disclosure control system are met and, as set forth above, our Chief Executive Officer and our Chief Financial Officer have concluded, based on their evaluation as of the end of the period covered by this quarterly report, that our disclosure controls and procedures were effective to provide reasonable assurance that the objectives of our disclosure control system were met.

**PART II — OTHER INFORMATION**

**ITEM 1. LEGAL PROCEEDINGS**

From time to time, we may become involved in litigation or other legal proceedings. We are not currently a party to any litigation or legal proceedings that, in the opinion of our management, are likely to have a material adverse effect on our business. Regardless of outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources, and other factors.

**ITEM 1A. RISK FACTORS**

There have been no material changes from the risk factors disclosed in Part I, Item 1A. "Risk Factors" of our 2025 Annual Report. The risk factors described in our 2025 Annual Report, as well as other information set forth in this Quarterly Report on Form 10-Q, could materially adversely affect our business, financial condition, results of operations and prospects, and should be carefully considered. The risks and uncertainties that we face, however, are not limited to those described in the 2025 Annual Report. Additional risks and uncertainties not presently known to us or that we currently believe to be immaterial may also adversely affect our business.
