All adjustments that, in the opinion of management, are necessary for a fair presentation of the results of operations for the interim periods have been made and are of a recurring nature unless otherwise disclosed herein. The results of operations for such interim periods are not necessarily indicative of the results of operations for a full year. These unaudited condensed consolidated financial statements should be read in conjunction with the consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the U.S. Securities and Exchange Commission (the "SEC") on February 27, 2025 (the "2024 Annual Report"). All significant intercompany balances and transactions have been eliminated in consolidation.

The Company calculates the fair value of its assets and liabilities which qualify as financial instruments and includes this additional information in the notes to unaudited condensed consolidated financial statements when the fair value is different from the carrying value of these financial instruments. The estimated fair value of short-term investments, accounts receivable, accounts payable and accrued expenses approximate their carrying amounts due to the relatively short maturity of these instruments. Notes payable and financing and operating leases approximate fair value as they bear market rates of interest. None of these instruments are held for trading purposes.

<u>Reverse Stock Split</u>

The Company effected a 1-for-20 reverse stock split on March 22, 2024. Unless otherwise stated, all share and per share amounts for all periods presented have been adjusted to reflect the reverse stock split.

<u>Short-term Investments</u>

Short-term investments consist of highly liquid, investment-grade fixed income securities, such as corporate bonds, asset-backed securities, municipal securities, U.S. Treasury and agency securities, and money market funds. These investments have maturities of greater than 90 days and less than one year from the balance sheet date and are intended to be available to meet current operational needs. As of June 30, 2025, the Company had $3.7 million in short-term investments.

**3.** **Right-of-use Asset and Leasing Liabilities** 

The Company has operating and finance leases where it records the right-of-use ("ROU") assets, and a related lease liability as required under the Financial Accounting Standard Board's ("FASB") Accounting Standards Codification ("ASC") 842. The lease liabilities are determined by the net present value of total lease payments and amortized over the life of the lease. The Company's leases are for the following types of assets:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· Computer hardware and copy machines- The Company's finance lease right-of-use assets consist of computer hardware and copy machines. These leases have two and three year lives and are in various stages of completion.

· Office space - The Company's operating lease right-of-use assets include its rental agreements for its offices in Plano, Texas, and a data service center in Allen, Texas. The Plano offices operating lease expires on April 30, 2035. The data service center operating lease liability has a life of four months as of June 30, 2025.

In accordance with ASC 842, the Company has elected practical expedients to combine lease and non-lease components, which consist principally of common area maintenance charges, for all classes of underlying assets and to exclude leases with an initial term of 12 months or less.

As the implicit rate is not readily determinable for the Company's lease agreements, the Company uses an estimated incremental borrowing rate to determine the initial present value of lease payments.

For the three and six months ended June 30, 2025, the Company made operating lease payments of $0.1 million and $0.2 million, respectively, compared to $32 thousand and $37 thousand for the same periods in 2024. For the same periods, finance lease payments were $0.1 million and $0.2 million in 2025, and $0.2 million and $0.3 million in 2024, respectively.

**4.** **Notes Payable** 

<u>Security Purchase Agreement</u>

On March 10, 2022, the Company entered into an unsecured loan agreement ("SPA") with Streeterville Capital, LLC ("Streeterville") pursuant to which the Company issued two separate promissory notes of $5.4 million each with an initial rate of 7%. Under this agreement, the Company received $4.6 million in net funds from the first tranche (Note 1) on March 10, 2022, and $4.7 million in net funds from the second tranche (Note 2) on June 29, 2022. Each note carried an 18-month maturity and had redemption provisions after six months in amounts up to $0.5 million per calendar month at the noteholder's discretion.

On January 11, 2023, the Company amended the promissory notes issued pursuant to the unsecured loan agreement with Streeterville whereby the noteholder agreed to waive their redemption rights through March 31, 2023, in exchange for a fee equal to 3.75% of the outstanding principal balance which increased the outstanding indebtedness due at maturity with Streeterville and increased the associated debt issuance costs recorded on the unaudited condensed consolidated balance sheets by $0.4 million.

On August 2, 2023, the Company entered into a Forbearance Agreement with Streeterville which was subsequently amended on August 7, 2023. The Forbearance Agreement and amendment extended the maturity dates for each Note by 12 months to September 2024 and December 2024. In consideration of the extension of the maturity dates, the Company entered into a Security Agreement with Streeterville, dated August 2, 2023 (the "Security Agreement"), under which Streeterville was granted a first-position security interest in all assets of the Company.

In March 2024, the Company entered into an agreement with Streeterville to exchange $0.2 million in principal for 52.2 thousand shares of common stock. Also in March 2024, the Company exchanged $9.3 million in Streeterville debt for 9.3 thousand shares of newly created Series A preferred stock. The issuance of both common and preferred shares was made pursuant to the exemption from the registration requirements afforded by the Securities Act of 1933, as amended (the "Securities Act"). Following the exchanges as noted herein, the remaining balance on Note 1 was $0.5 million, Note 2 was paid in full, the interest accretion associated with the ability to stock-settle principal redemptions was reversed and the Company wrote off the balance of unamortized debt issuance costs.

The maturity date for Note 1 was September 10, 2024; however, the preferences for Series A preferred stock precluded repayment of Note 1 so long as any shares of Series A preferred stock were outstanding. The Series A preferred stock was repaid in full on January 3, 2025. In March 2025, the Company entered into three separate agreements with Streeterville to exchange an aggregate $0.5 million in principal for 552.3 thousand shares of common stock, thereby retiring the remainder of Note 1 in full. The issuance of both common and preferred shares was made pursuant to the exemption from the registration requirements afforded by the Securities Act.

For the six months ended June 30, 2025, and 2024, the Company recorded simple interest of $8 thousand and $153 thousand, respectively. In March 2024, as a result of exchanging $9.5 million principal in aggregate for equity, the Company reversed the interest accretion associated with the ability to stock-settle principal redemptions and wrote off the balance of unamortized debt issuance costs resulting in a credit of $1.0 million to interest expense in the unaudited condensed consolidated statement of operations for the six months ended June 30, 2024.

<u>Scott Notes Payable</u>

In March 2024, the Company entered into two separate note purchase agreements with Anthony Scott, the Company's President and Chief Executive Officer and member of the Company's Board of Directors. On January 2, 2024, Mr. Scott purchased a note payable in the principal amount of $1.1 million in exchange for $1.0 million in cash. The note called for weekly payments of $40 thousand until maturity on June 15, 2024. Interest accrued on the balance of the note at 7% per annum compounding daily. During the period ended June 30, 2024, the Company made $0.2 million in principal payments on the first note payable.

On March 20, 2024, Mr. Scott purchased a second note payable in the principal amount of $343 thousand in exchange for $340 thousand in cash. The note was non-interest bearing and matured on April 19, 2024. On April 2, 2024, the Company reduced the principal balance due under the note by $101 thousand, which reflected the amount due from Mr. Scott for the exercise of common stock purchase warrants.

On April 19, 2024, Mr. Scott entered into a private placement subscription agreement to convert the aggregate outstanding balance of $1.1 million for both notes in exchange for common stock and common stock purchase warrants.

The Company recorded interest expense of $20 thousand for both notes in the accompanying condensed consolidated statement of operations for the six months ended June 30, 2024. For the six months ended June 30, 2024, $83 thousand in amortization of debt issuance cost was recorded.

**5.** **Commitments and Contingencies** 

The Company is periodically involved in various litigation claims asserted in the normal course of its business. The Company believes these actions are routine and incidental to the business. While the outcome of these actions cannot be predicted with certainty, the Company does not believe that any will have a material adverse impact on the Company's business.

**6.** **Stockholders' Equity** 

***ATM Offering***

 

On June 11, 2025, the Company terminated its At Market Sales Agreement with B. Riley Securities, Inc. (the "Riley ATM Agreement"). On June 12, 2025, the Company entered into a new At The Market Offering Agreement with H.C. Wainwright & Co., LLC to potentially sell up to $50.0 million of the Company's common stock using a shelf registration statement on Form S-3/A (File No. 333-281565) which was filed on January 31, 2025 and became effective on February 10, 2025. For the period ended June 30, 2025, no sales of common stock were made under the ATM utilizing the shelf registration. For the period ended June 30, 2024, the Company received proceeds of approximately $3.3 million net of fees from the sale of common stock pursuant to the Riley ATM Agreement.

***Standby Equity Purchase Agreement***

On July 3, 2024, the Company entered into a $10 million Standby Equity Purchase Agreement ("SEPA") with Streeterville pursuant to which the Company has the right to direct Streeterville during the 24-month term of the agreement to purchase common stock subject to certain limitations and conditions set forth in the SEPA. During the year ended December 31, 2024, 1.2 million shares of common stock were purchased pursuant to the SEPA resulting in aggregate net proceeds of $1.8 million of which $0.1 million was received in 2024. The remaining proceeds due were recorded as a stock subscription receivable in the consolidated balance sheet on December 31, 2024, and received in January 2025. During the six months ended June 30, 2025, no purchases were made pursuant to the SEPA.

***Series A Preferred Stock***

On March 15, 2024, the Company filed the Amended and Restated Certificate of Incorporation (the "A&R Certificate") to eliminate the Series 1, Series 2, and Series 3 preferred shares and filed a Certificate of Designations creating a new Series A preferred stock, $0.01 par value per share (the "Series A preferred stock"). Pursuant to the terms of the Series A Certificate, 20 thousand shares of Series A preferred stock are authorized, and each share of Series A preferred stock has a stated value of $1,100, accrues a rate of return on the stated value of 10% per year, is compounded annually and is payable quarterly in cash or additional shares of Series A preferred stock.

On March 15, 2024, the Company entered into an Exchange Agreement with Streeterville Capital that exchanged $9.3 million in debt for 9,275 shares of Series A preferred stock.

On April 3, 2024, and continuing through December 31, 2024, in nine separate exchange transactions, the Company exchanged an aggregate of 6,123 shares of Series A preferred stock for 2,637.7 thousand shares of our common stock. All the exchanges were made pursuant to the exemption from the registration requirements afforded by Section 3(a)(9) of the Securities Act. Also in 2024, the Company redeemed 17 shares of Series A preferred stock in conjunction with the sale of common stock under the SEPA and redeemed 90 shares of Series A preferred stock in conjunction with entering into a separate financing agreement with Streeterville as more fully described in the 2024 Annual Report.

Both exchanges were made pursuant to the exemption from the registration requirements afforded by Section 3(a)(9) of the Securities Act. Also in January 2025, the Company redeemed 170 shares of Series A preferred stock in conjunction with the receipt of proceeds from the sale of common stock under the SEPA.

***Registered Direct Offering***

On January 6, 2025, the Company sold to a single institutional investor 653 thousand shares of the Company's common stock at a purchase price of $3.05 per share and 1,806 thousand prefunded warrants to purchase up to 1,806 thousand shares of common stock at a purchase price of $3.0499 for aggregate gross proceeds of $7.5 million. The prefunded warrants were exercisable immediately at an exercise price of $0.0001 per share subject to the purchaser not being deemed a beneficial owner of greater than 4.99%. All of the pre-funded warrants were exercised in January 2025.

***Common Stock Warrants***

On June 30, 2025, the Company had 3,198,085 warrants to purchase common stock at an average exercise price of $3.26 per share and average remaining term of 3.9 years.

**7.** **Stock-Based Compensation** 

The Company accounts for stock-based compensation in accordance with ASC 718, Compensation – Stock Compensation, which requires that compensation related to all stock-based awards be recognized in the condensed consolidated financial statements. Stock-based compensation cost is valued at fair value at the date of grant, and the grant date fair value is recognized as expense over each award's requisite service period with a corresponding increase to equity or liability based on the terms of each award and the appropriate accounting treatment under ASC 718.

The Company had three stock-based compensation plans as of June 30, 2025, and December 31, 2024, the 2021 Omnibus Incentive Plan, the 2015 Stock Incentive Plan and the 2005 Stock Incentive Plan.

The Company grants stock from both the 2021 Omnibus Incentive Plan and the 2015 Stock Incentive Plan. These plans provide a means through which the Company may attract and retain key personnel and to provide a means whereby directors, officers, employees, consultants and advisors of the Company can acquire and maintain an equity interest in the Company, or be paid incentive compensation, including incentive compensation measured by reference to the value of common stock, thereby strengthening their commitment to the welfare of the Company and aligning their interests with those of the Company's stockholders.

During the six months ended June 30, 2025, the Company granted 383.9 thousand restricted stock units ("RSUs"). No other grants were made during the period.

The Company recognized compensation expense of $0.3 million and $0.5 million for the three and six months ended June 30, 2025, respectively, compared to $0.1 million and $0.2 million for the three and six months ended June 30, 2024, respectively.

**8.** **Revenue Recognition** 

The Company recognizes product revenue upon shipment or after meeting certain performance obligations. These products can include hardware, software subscriptions and consulting services. The Company also offers software on a subscription basis subject to software as a service ("SaaS"). Warranty costs have not been material.

The Company recognizes sales of the Company's datasets in accordance with FASB ASC Topic 606 whereby revenue from contracts with customers are recognized once the criteria under the five steps below have been met:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;(i) identification of the contract with a customer;

(ii) identification of the performance obligations in the contract;

(iii) determination of the transaction price;

(iv) allocation of the transaction price to the separate performance obligations; and

(v) recognize revenue upon satisfaction of a performance obligation.

Consulting services include reporting and are typically done monthly, and revenue is matched accordingly.

Normal payment terms offered to customers, distributors and resellers are net 30 days domestically. The Company does not offer payment terms that extend beyond one year and rarely does it extend payment terms beyond its normal terms. If certain customers do not meet the Company's credit standards, the Company typically requires payment in advance to limit its credit exposure.

With the Company's newest product, **INTRUSION *Shield,*** the Company began offering software on a subscription basis. **INTRUSION *Shield*** is a hosted arrangement subject to SaaS guidance under ASC 606. SaaS arrangements are accounted for as subscription services, not arrangements that transfer a license of intellectual property.

The Company utilizes the five-step process mentioned above, per FASB ASC Topic 606 to recognize sales and will follow that directive, also, to define revenue items as individual and distinct. **INTRUSION *Shield*** services provided to its customers for a fixed monthly subscription fee include:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;· access to Intrusion's proprietary software and database to detect and prevent unauthorized access to its clients' information networks;

· use of all software, associated media, printed materials, data, files, online documentation, and any equipment that Intrusion provides for customers to access the **INTRUSION *Shield*** ; and

· tech support, post contract customer support (PCS) includes daily program releases or corrections provided by Intrusion without additional charge.

**INTRUSION *Shield*** contracts provide no other services, and the Company's customers have no rebates or return rights, nor are any such rights anticipated to be offered as part of this service.

The Company satisfies its performance obligation when the **INTRUSION *Shield*** solution is available to detect and prevent unauthorized access to a client's information networks. Revenue is recognized monthly over the term of the contract. The Company's standard initial contract terms automatically renew unless notice is given 30 days before renewal. Upfront payment of fees is deferred and amortized into income over the period covered by the contract.

For the three and six months ended June 30, 2025, revenues to various U.S. government entities totaled $1.8 million from 4 government customers and $3.4 million from 4 government customers, representing 95.5% and 93.6% of total revenues, respectively. In comparison, for the same periods in 2024, revenues totaled $1.3 million from 5 government customers and $2.0 million from 6 government customers, representing 89.0% and 75.7% of total revenues, respectively.

The Company's accounts receivable represents unconditional contract billings for sales per contracts with customers and are classified as current assets. As of June 30, 2025, and December 31, 2024, the Company had accounts receivable balances of $0.1 million and $0.2 million, respectively. As of June 30, 2025, and December 31, 2024, the Company had an allowance for credit losses of $0.1 million.

Contract assets are recognized when the Company has transferred services to a customer earning the right to consideration.

Contract liabilities consist of cash payments in advance of the Company satisfying performance obligations and recognizing revenue. The Company currently classifies deferred revenue as a contract liability.

The following tables presents changes in the Company's contract assets and contract liabilities during the six months ended June 30, 2025, and the year ended December 31, 2024 (in thousands):

---

| | | |
|:---|:---|:---|

**9.** **Capitalized Software Development** 

The Company capitalizes internally developed software using the Agile software development methodology which allows the Company to accurately track, and record costs associated with new software development and enhancements.

Pursuant to ASC Topic 350-40 Internal Use Software Accounting Capitalization, certain development costs related to the Company's products during the application development stage are capitalized as part of property and equipment. Costs incurred in the preliminary stages of development are expensed as incurred. The preliminary stage includes activities such as conceptual formulation of alternatives, evaluation of alternatives, determination of existence of needed technology, and the final selection of alternatives. Once the application development stage is reached, internal and external costs are capitalized until the software is complete and ready for its intended use. Capitalized internal use software is amortized on a straight-line basis over its estimated useful life, which is generally three years.

**10.** **Net Loss Per Share** 

The Company reports two separate net loss per share numbers, basic and diluted. Basic net loss attributable to common stockholders per share is computed by dividing net loss attributable to common stockholders for the period by the weighted average number of common shares outstanding for the period. Diluted net loss attributable to common stockholders per share is computed by dividing the net loss attributable to common stockholders for the period by the weighted average number of common shares and dilutive common stock equivalents outstanding for the period. The common stock equivalents include all common stock issuable upon exercise of outstanding warrants, options and vesting of restricted stock awards. The aggregate number of common stock equivalents excluded from the diluted loss per share calculation for the three months ended June 30, 2025, and 2024 totaled 3.8 million and 3.1 million shares, respectively. The aggregate number of common stock equivalents excluded from the diluted loss per share calculation for the six months ended June 30, 2025, and 2024 totaled 3.8 million and 1.7 million shares, respectively. Since the Company is in a net loss position for the periods ended June 30, 2025, and 2024, basic and dilutive net loss per share is the same.

**11.** **Related Party Transactions** 

On January 2, 2024, the Company entered into an invoice financing arrangement pursuant to a note purchase agreement with Mr. Scott, President, and Chief Executive Officer of the Company and a member of the Board, according to which, among other things, Mr. Scott purchased from the Company a promissory note (the "Promissory Note") in the aggregate principal amount of $1.1 million in exchange for $1.0 million to the Company. Interest accrued at a rate of 7.0% per annum, compounded daily. Under the Promissory Note, the Company made principal payments to Mr. Scott in the aggregate amount of $0.2 million. On March 20, 2024, the Company entered into an additional invoice financing arrangement pursuant to a note purchase agreement with Mr. Scott, according to which, among other things, Mr. Scott purchased from the Company a second Promissory Note 2 in the aggregate principal amount of $343 thousand in exchange for $340 thousand to the Company. Promissory Note 2 was non-interest bearing and matured on April 19, 2024.

On April 2, 2024, the Company reduced the principal balance due under the Promissory Note by $0.1 million which reflected the amount due from Mr. Scott for the exercise of common stock purchase warrants. On April 19, 2024, Mr. Scott entered into a private placement subscription agreement to convert the aggregate outstanding balance of $1.1 million for both notes in exchange for common stock and common stock purchase warrants.

The Company recorded interest expense of $20 thousand for both notes in the accompanying consolidated statement of operations for the six months ended June 30, 2024. For the six months ended June 30, 2024, $83 thousand in amortization of debt issuance cost was recorded.

There were no related party transactions for the three or six months ended June 30, 2025.

**Revenue**. Revenue for the three and six months ended June 30, 2025, was $1.9 million and $3.6 million, respectively, compared to $1.5 million and $2.6 million for the same periods in 2024. Consulting revenue totaled $1.4 million and $2.7 million for the three and six months ended June 30, 2025, up from $1.2 million and $1.9 million for the corresponding periods in 2024. The increase in consulting revenue in 2025 primarily reflects work performed under a Department of Defense contract awarded in the second half of 2024. In contrast, consulting revenue for the six months ended June 30, 2024, was negatively impacted by a continuing resolution and delays in the approval of the federal budget. The budget was not passed until March 22, 2024, which affected the timing of contract renewals and task orders and led to lower consulting revenues in the first half of 2024. INTRUSION *Shield* revenue was $0.5 million and $0.9 million for the three and six months ended June 30, 2025, compared to $0.3 million and $0.7 million for the same periods in 2024. On March 31, 2024, we lost a major INTRUSION *Shield* customer who used a highly customized product configuration. This customer accounted for 78% of INTRUSION *Shield* revenues; this loss has been fully offset by new customers inclusive of the Department of Defense contract awarded in late 2024.

**Concentration of Revenues.** For the three and six months ended June 30, 2025, revenues from sales to various U.S. government entities totaled $1.8 million and $3.4 million, comprising 95.5% and 93.7% of total revenues, respectively. This compares to $1.3 million and $2.0 million, or 89.0% and 75.7% of total revenues, for the same periods in 2024. The shift in revenue mix was primarily due to the loss of a significant Shield customer, as previously noted, and the addition of a Department of Defense contract in the second half of 2024.

We expect our revenue concentration among customers to fluctuate in future periods, depending on the timing of sales; however, we anticipate that sales to government customers will continue to represent a significant portion of our revenues. Sales to government entities involve certain risks beyond those associated with commercial customers, including potential disruptions in appropriations and spending, and the government's right to cancel contracts and purchase orders at its convenience. While we do not currently anticipate renegotiations or cancellations of government contracts, the loss of government orders could materially affect our financial results. Given the increased percentage of sales to U.S. government entities in 2025, no individual commercial customer accounted for more than 10% of total revenues, compared to one such customer in the prior year. Our product and service offerings are not managed as separate segments, as management evaluates the business as a whole and does not allocate expenses by product.

**Gross Profit.** Gross profit was $1.4 and $2.8 million or 76.4% and 76.0% of revenues for the three and six month periods ended June 30, 2025, compared to $1.1 and $2.0 million or 76.0% and 77.8% of revenues for the three and six months ended June 30, 2024. The gross profit margin will vary depending on product mix. INTRUSION Shield revenues represent between 25% and 28% of revenues for the six month periods ended June 30, 2025, and 2024.

**Operating Expenses.** Operating expenses totaled $3.5 million and $7.0 million for the three- and six-month periods ended June 30, 2025, compared to $3.1 million and $6.5 million for the same periods in 2024. The 2024 figures include one-time negotiated contract savings of $0.1 million for the three-month period and $0.4 million for the six-month period.

Adjusting for these one-time savings, operating expenses for the three months ended June 30, 2025, increased by $0.3 million, primarily due to higher share-based compensation from equity grants made in the first quarter, timing of merit increases, and the addition of a Sales Engineer and Software Engineer. These increases were partially offset by lower legal fees following the resolution of prior-year litigation matters and increased allocations from operating expenses to cost of sales for resources dedicated to additional consulting work during the quarter.

For the six months ended June 30, 2025, operating expenses, when adjusted for one-time savings, were $0.1 million higher than the comparable period in 2024.

**Sales and Marketing.** Sales and marketing expenses totaled $1.2 million and $2.4 million for three and six months ended June 30, 2025, respectively. The 2024 period includes approximately $0.1 million in one-time negotiated contract savings. We anticipate increasing our spend to create more brand awareness, concise product messaging and drive increased sales through the remainder of 2025.

**Research and Development.** Research and development expenses totaled $1.3 million and $2.6 million for the three and six months ended June 30, 2025, representing an increase of $0.3 million and $0.5 million when compared to the same periods in the prior year. The increase is primarily due to increased depreciation of $0.1 million on infrastructure hardware purchases and internally developed software as we continue to invest in adding new features and functionality to the INTRUSION *Shield* and higher expense due to the 2024 period including one-time negotiated savings of $0.1 million. Research and development costs may vary over time as we determine the frequency of new releases, improved functionality and enhancements needed to be competitive with our product offering.

**General and Administrative.** General and administrative expenses totaled $1.0 and $2.0 million for the three and six months ended June 30, 2025, compared to $1.0 and $2.1 million for the three and six months ended June 30, 2024. The reduction is primarily due to decreased legal expenses as a result of the prior year's litigation matters being fully resolved and one-time negotiated savings included in the 2024 period.

**Interest Expense.** Interest expense for the three and six month periods ended June 30, 2025, was $21 and $50 thousand, respectively, consisting principally of imputed interest on finance leases and the stated interest related to the Streeterville note that was fully retired in the first quarter of 2025. Interest expense for the 2024 periods totaled $34 and $262 thousand and consisted principally of the stated interest related to the Streeterville notes, interest associated with the notes payable issued to Anthony Scott, the Company's President and Chief Executive Officer and a member of the Company's Board of Directors, and finance leases.

**Interest Accretion and Amortization of Debt Issuance Costs.** During the March 2024 quarter, we entered into exchange agreements to convert $9.5 million in Streeterville debt to $9.3 million shares of Series A preferred stock and $0.2 million to common stock and, as a result, we reversed the interest accretion associated with the ability to stock-settle principal redemptions and wrote-off the remaining deferred debt issue costs resulting in a net credit to interest expense of $1.0 million.

**Other Income (Expense), Net.** Other income and expense were nominal amounts for both the three and six months ended June 30, 2025, and 2024.

**Net Loss.** Net loss for the three and six month periods ended June 30, 2025, was ($2.0) million and ($4.1) million, respectively compared to ($2.1) million and ($3.8) million for the same periods in the prior year. The increase in net loss for six months ended June 30, 2025, was a result of a net interest credit of $1.0 million recorded in the 2024 period as discussed above.

<u>Liquidity and Capital Resources</u>

*Sources of Liquidity*

As of June 30, 2025, we had cash and cash equivalents of $4.7 million, representing a decrease of ($0.2) million from $4.9 million as of December 31, 2024, and net working capital of $7.2 million compared to $1.9 million as of December 31, 2024. Our principal sources of cash for funding operations for the six months ended June 30, 2025 was receipt of $1.5 million in proceeds from the sale of common stock pursuant to the SEPA, recorded as stock subscription receivable at December 31, 2024, and net proceeds of $7.0 million from a registered direct offering that closed on January 6, 2025. Our principal source for funding operations in the June 2024 period was through proceeds received from the issuance of common stock in a series of transactions which include $3.3 million from ATM sales, $2.6 million from a private placement, and $0.6 million from the exercise of warrants.

**<u>ATM Program</u>**

On June 11, 2025, we terminated our At Market Sales Agreement with B. Riley Securities, Inc. The following day, on June 12, 2025, we entered into a new At The Market Offering Agreement (the "Sales Agreement") with H.C. Wainwright & Co., LLC to potentially sell up to $50.0 million of the Company's common stock using a shelf registration statement on Form S-3/A (File No. 333-281565) which was filed on January 31, 2025 and became effective on February 10, 2025. No sales under the new shelf registration have been made to date.

**<u>Notes Payable</u>**

In March 2025, through three separate exchange agreements we retired the remaining $0.5 million in Streeterville debt through the issuance of 552.3 thousand shares of common stock. The issuance of common stock was made pursuant to the exemption from the registration requirements afforded by the Securities Act.

 ****

Net proceeds from financing activities for the June 2024 period totaled $6.1 million which resulted from $6.5 million in net proceeds from the sale of common stock through the use our ATM program, a private placement offering, and the exercise of warrants partially offset by finance lease payments.

**Critical Accounting Policies and Use of Estimates**

Our unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP. The preparation of these unaudited condensed consolidated financial statements requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenue, expenses, and related disclosures. We base our estimates on historical experience and on various other assumptions that we believe are reasonable under the circumstances. We evaluate our estimates and assumptions on an ongoing basis. Actual results may differ from these estimates. To the extent that there are material differences between these estimates and our actual results, our future financial statements will be affected.

We believe the critical accounting policies and estimates discussed under "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 27, 2025 (the "2024 Annual Report"), reflect our more significant judgments and estimates used in the preparation of the condensed consolidated financial statements. There have been no significant changes to our critical accounting policies and estimates as disclosed in the 2024 Annual Report.

**Item 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK**

Not applicable.

**Item 4. CONTROLS AND PROCEDURES**

*Evaluation of Effectiveness of Disclosure Controls and Procedures*

We maintain "disclosure controls and procedures," as defined in Rule 13a-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed by us in 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 our principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. In designing and evaluating our disclosure controls and procedures, management recognized that disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable assurance of achieving the desired control objectives, and we must apply our reasonable judgment in evaluating the cost-benefit relationship of potential disclosure controls and procedures.

As of June 30, 2025, our management, including our principal executive officer and principal financial officer, evaluated the effectiveness of the design and operation of our disclosure controls and procedures and concluded that the disclosure controls and procedures were effective as of June 30, 2025.

*Changes in Internal Control over Financial Reporting*

There have not been any changes in our internal control over financial reporting that occurred during the three months ended June 30, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**PART II – OTHER INFORMATION**

**Item 1. LEGAL PROCEEDINGS**

As of June 30, 2025, the Company was not involved in any material pending legal proceedings. The Company is periodically involved in various litigation claims asserted in the normal course of its business. The Company believes these actions are routine and incidental to the business. While the outcome of these actions cannot be predicted with certainty, the Company does not believe that any will have a material adverse impact on the Company's business.

**Item 1A. RISK FACTORS** 

As a smaller reporting company, as such term is defined in Item 10(f) of Regulation S-K, promulgated under the Exchange Act, risk factors are not required to be included in, and have been omitted from, this Quarterly Report on Form 10-Q.

These risks could materially and adversely affect our business, financial condition, results of operations, and cash flows. However, these risks are not the only risks we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial also may impair our business, financial condition, results of operations, and cash flows.
