**MATINAS BIOPHARMA HOLDINGS, INC.**

**Notes to Unaudited Condensed Consolidated Financial Statements**

**(Tabular dollars and shares in thousands, except per share data)**

**Note 1 – Description of Business**

Matinas BioPharma Holdings Inc. ("Holdings") is a Delaware corporation formed in 2013. Holdings is the parent company of Matinas BioPharma, Inc. ("BioPharma"), and Matinas BioPharma Nanotechnologies, Inc. ("Nanotechnologies," formerly known as Aquarius Biotechnologies, Inc.), its operating subsidiaries ("Nanotechnologies", and together with "Holdings" and "BioPharma", "the Company"). The Company is a clinical-stage biopharmaceutical company focused on delivering groundbreaking therapies using its lipid nanocrystal (LNC) platform delivery technology (LNC Platform).

**Note 2 – Liquidity, Plan of Operations and Going Concern**

The Company has experienced net losses and negative cash flows from operations each period since its inception. Through June 30, 2025, the Company had an accumulated deficit of $206,725. The Company's net loss for the six months ended June 30, 2025 and 2024 was $6,901 and $11,543, respectively.

The Company expects operating expenses to be lower in the near term compared to recent years until such time as additional funding is secured to support initiation of the Phase 3 registration trial for MAT2203 and advancement of the LNC platform delivery technology. The Company expects that its research and development expenses will increase if it moves forward with additional clinical studies for its current product candidates and development of additional product candidates. If the Company obtains U.S. Food and Drug Administration ("FDA") approval for one or more of its product candidates, the Company expects that its expenses will continue to increase once the Company reaches commercial launch. As a result, the Company expects to continue to incur substantial losses for the foreseeable future, and that these losses will be increasing.

As of June 30, 2025, the Company had cash and cash equivalents of $6,525 and restricted cash of $250. The Company does not believe the cash and cash equivalents on hand are sufficient to fund planned operations beyond the next twelve months from the filing date of these financial statements. As a result, substantial doubt exists about the Company's ability to continue as a going concern.

The ability of the Company to continue as a going concern is dependent upon securing one or more partners to monetize the value of MAT2203, the ability to control its operating expenses, future sales of common stock through the At-The-Market Sales Agreement ("Sales Agreement") with BTIG, LLC and securing additional financing. While the Company believes in the viability of this strategy and believes the actions presently being taken by the Company provide the opportunity for it to continue as a going concern, there can be no assurance the Company will be successful in its implementation. In particular, utilization of the Sales Agreement may not be viable due to market conditions and new financing may not be available on acceptable terms, or at all. Moreover, under the terms of the Preferred Stock sales agreement, the Company is prohibited, subject to certain exceptions, from issuing, entering into any agreement to issue, or announcing the issuance or proposed issuance of any shares of common stock or common stock equivalents until November 2025. These consolidated financial statements do not include any adjustments related to the recoverability and classification of asset amounts or the amounts and classification of liabilities that might be necessary if the Company is unable to continue as a going concern.

**Note 3 – Summary of Significant Accounting Policies**

**Basis of presentation and principles of consolidation**

The accompanying unaudited condensed consolidated financial statements include the consolidated accounts of Holdings and its wholly owned subsidiaries, BioPharma, and Nanotechnologies. The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States ("U.S. GAAP") and reflect the operations of the Company and its wholly owned subsidiaries. All intercompany transactions have been eliminated in consolidation.

Other than the policies listed below, there have been no material changes to the Company's significant accounting policies are described in Note 3 within the Company's Notes to Consolidated Financial Statements included in the Company's Annual Report on Form 10-K for the year ended December 31, 2024.

In August 2020, the FASB issued Accounting Standard Update No. 2020-06 – *Debt: Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging – Contracts in Entity's Own Equity (Subtopic 815-40): Accounting for Convertible Instruments and Contracts in an Entity's Own Equity*, which simplifies accounting for convertible instruments by removing major separation models required under current GAAP. The ASU removes certain settlement conditions that are required for equity contracts to qualify for the derivative scope exception, and it also simplifies the diluted earnings per share calculation in certain areas. This ASU is effective for annual reporting periods beginning after December 15, 2021, including interim periods within those fiscal years. The Company adopted the ASU on January 1, 2025. This update permits the use of either the modified retrospective or fully retrospective method of transition.

The Company's management has considered all recent accounting pronouncements issued and believes that these recent pronouncements will not have a material effect on the Company's financial statements.

***Warrants***

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant's specific terms and applicable authoritative guidance in ASC 480, Distinguishing Liabilities from Equity and ASC 815, Derivatives and Hedging. Warrants classified as equity are recorded at fair value as of the date of issuance on the Company's condensed consolidated balance sheets and no further adjustments to their initial valuation are subsequently made. Warrants that require separate accounting as liabilities are recorded on the Company's condensed consolidated balance sheets at their fair value on the date of issuance and are revalued on each subsequent balance sheet date until such instruments are exercised or expired, with any changes in the fair value between reporting periods recorded on the condensed consolidated statement of operations. The assessment of whether the warrants are accounted for as equity-classified or liability-classified instruments is re-evaluated on a periodic basis. See Note 9 - *Stockholders' Equity* for a discussion on the Company's warrants.

**Note 4 – Cash, Cash Equivalents, Restricted Cash and Marketable Debt Securities**

The Company considers all highly liquid financial instruments with original maturities of three months or less when purchased to be cash and cash equivalents and all investments with maturities of greater than three months from date of purchase are classified as marketable debt securities. Cash and cash equivalents consist of cash in bank checking and savings accounts, money market funds and short-term U.S. treasury bonds that mature within three months of settlement date.

*Cash, Cash Equivalents and Restricted Cash*

The Company presents restricted cash with cash and cash equivalents in the Condensed Consolidated Statements of Cash Flows. Restricted cash at both June 30, 2025 and December 31, 2024 of $250 represents funds the Company is required to set aside as collateral, primarily for one of the Company's operating leases.

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported in the Condensed Consolidated Balance Sheets to the total of the amounts in the Condensed Consolidated Statements of Cash Flows as of June 30, 2025, December 31, 2024, June 30, 2024 and December 31, 2023:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **June 30, 2025** | **December 31, 2024** | **June 30, 2024** | **December 31, 2023** |
| Cash and cash equivalents | $6525 | $7284 | $4216 | $4787 |
| Restricted cash included in current/non-current assets | 250 | 250 | 250 | 250 |
| Cash, cash equivalents and restricted cash in the statement of cash flows | $6775 | $7534 | $4466 | $5037 |

---

*Marketable Debt Securities*

The Company has classified its investments in marketable debt securities as available-for-sale and as a current asset. The Company's investments in marketable debt securities are carried at fair value, with unrealized gains and losses included as a separate component of stockholders' equity. Unrealized losses and gains are classified as other comprehensive (loss)/income and costs are determined on a specific identification basis. Realized gains and losses from our marketable debt securities are recorded in other income, net. The Company did not incur any realized gains and losses during the six months ended June 30, 2025 and 2024. For the six months ended June 30, 2025 and 2024, the Company recorded unrealized gains of $0 and $170, respectively.

**Note 5 - Fair Value Measurements**

The Company uses the fair value hierarchy to measure the value of its financial instruments. The fair value hierarchy is based on inputs to valuation techniques that are used to measure fair value that are either observable or unobservable. Observable inputs reflect assumptions market participants would use in pricing an asset or liability based on market data obtained from independent sources, while unobservable inputs reflect a reporting entity's pricing based upon its own market assumptions. The basis for fair value measurements for each level within the hierarchy is described below:

● Level 1 – Quoted
 prices for identical assets or liabilities in active markets.

● Level 2 – Quoted
 prices for identical or similar assets and liabilities in markets that are not active; or other model-derived valuations whose inputs
 are directly or indirectly observable or whose significant value drivers are observable.

● Level 3 – Valuations
 derived from valuation techniques in which one or more significant inputs to the valuation model are unobservable and for which assumptions
 are used based on management estimates.

The Company utilizes valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs to the extent possible as well as counterparty credit risk in its assessment of fair value.

The carrying amounts of cash equivalents, current portion of restricted cash, prepaid expenses and other current assets, accounts payable, current portion of lease liabilities and accrued expenses approximate fair value due to the short-term nature of these instruments.

The Company did not have any financial assets or liabilities that were carried at fair value using the hierarchy as of either June 30, 2025 or December 31, 2024.

The table below presents a summary of changes in fair value of the warrant liability that was measured at fair value on a recurring basis:

---

| | |
|:---|:---|
|  | **Warrant Liability** |
| Balance at January 31, 2025 |  |
| Issuance of warrants reported at fair value | 2942 |
| Change in fair value | 3161 |
| Reclassification to equity | (6103) |
| Balance at June 30, 2025 |  |

---

On February 13, 2025, the Company entered into a securities purchase agreement with certain investors and, pursuant to an initial and second closing under the agreement, issued and sold to the investors an aggregate of (i) 3,300 shares of convertible preferred stock and (ii) warrants (the "Warrants") to purchase up to 11,262,808 shares of the Company's common stock (see Note 9).

The Company classified the Warrants as a liability upon issuance. Accordingly, proceeds from the transaction were first allocated to the Warrants which were recorded at fair value at issuance, and any residual value allocated to preferred stock. Subsequent changes in fair value of the Warrants were recognized in the Company's condensed consolidated statements of operations and comprehensive loss.

On June 26, 2025, the terms of the Warrants were amended to remove the provision that provided for a potential adjustment to the Warrants that did not meet the indexation requirements. The Company determined that the Warrants now satisfy the conditions to be accounted for as equity instruments. The change in fair value of the Warrants until June 26, 2025 was recorded in the income statement and fair value of the Warrants on June 26, 2025, was reclassified to equity. There will be no subsequent measurement for the equity classified Warrants as long as the indexation and equity classification criteria continue to be met.

For each reporting period during which the Warrants were classified as a liability, the Company's warrant liability was measured at fair value utilizing a Monte Carlo simulation model, which required assumptions including the value of the stock on the measurement date, exercise price, expected term, expected volatility, and the risk-free interest rate. Certain assumptions, including the expected term and expected volatility, were subjective and require judgment to develop.

The warrant liabilities were valued on the various measurement dates during the six months ended June 30, 2025 using the following range of assumptions:

---

| | |
|:---|:---|
| Expected volatility | 54.0% - 61.0 |
| Risk-free interest rate | 3.77% – 4.39 |
| Stock price on valuation date | $0.52 - 0.94 |
| Exercise price | $0.64 |
| Dividend yield | 0.00% |
| Expected term | 4.8 - 5.0 years |

**Note 6 – Leasehold Improvements and Equipment**

Leasehold improvements and equipment, summarized by major category, consist of the following as of June 30, 2025 and December 31, 2024:

---

| | | |
|:---|:---|:---|
|  | **June 30, 2025** | **December 31, 2024** |
| Equipment | $— | $283 |

| Less: accumulated depreciation and amortization | 60 | 33 |
| &nbsp;&nbsp;&nbsp;Leasehold improvements and equipment, net | $158 | $468 |

---

Depreciation and amortization expense for the three and six months ended June 30, 2025 and 2024 was $12 and $30, respectively. Depreciation and amortization expense for the three and six months ended June 30, 2024 was $90 and $184, respectively.

***Assets held for sale, net***

 

On April 19, 2025, the Company initiated a process to sell certain unused laboratory equipment that was previously impaired and carried a net book value of $280. During the three months ended June 30, 2025, the Company sold $210 of the equipment, generating proceeds of $320 and a gain of $110. As of June 30, 2025, the remaining $70 of equipment is classified as held for sale on the Company's balance sheet. We expect the remaining equipment to be sold prior to December 31, 2025.

**Note 7 – Accrued Expenses and Other Liabilities**

**Note 8 – Leases**

The Company has various lease agreements, including leases of office space, a laboratory and manufacturing facility, and various equipment. Some leases include purchase, termination or extension options for one or more years. These options are included in the lease term when it is reasonably certain that the option will be exercised.

The assets and liabilities from operating and finance leases are recognized at the lease commencement date based on the present value of remaining lease payments over the lease term using the Company's incremental borrowing rates or implicit rates, when readily determinable. Short-term leases, which have an initial term of 12 months or less, are not recorded on the balance sheet. The Company's operating leases do not provide implicit rates, therefore the Company utilized a discount rate based on its incremental borrowing rate to record the lease obligations. The Company's finance leases provide readily determinable implicit rates.

*Operating lease obligations*

The Company incurred lease expense for its operating leases of $171 and $226 for the three months ended June 30, 2025 and 2025, respectively, and $345 and $452 for the six months ended June 30, 2025 and 2024, respectively. The Company incurred amortization expense on its operating lease right-of-use assets of $111 and $149 for the three months ended June 30, 2025 and 2024, respectively, and $218 and $294 for the six months ended June 30, 2025 and 2024, respectively.

*Finance Leases*

The Company incurred interest expense on its finance leases of $0 for the three months ended June 30, 2025 and 2024 and $0 and $1 for the six months ended June 30, 2025 and 2024, respectively. The Company incurred amortization expense on its finance lease right-of-use assets of $1 and $2 for the three months ended June 30, 2025 and 2024, respectively, and $2 and $3 for the six months ended June 30, 2025 and 2024, respectively.

As of June 30, 2025, in accordance with the Certificate of Incorporation, the Company was authorized to issue 250,000,000 shares of common stock and 10,000,000 shares of preferred stock, each share having a par value of $0.0001.

**Common Stock**

On June 23, 2025, the Company received shareholder approval to increase the number of shares of common stock authorized for issuance to 500,000,000. On August 6, 2025, the Company filed a Certificate of Amendment (the "Certificate of Amendment") to the Company's Certificate of Incorporation, as amended, with the Secretary of State of the State of Delaware to increase the number of authorized shares of the Company's common stock from 250,000,000 shares to 500,000,000 shares. The Certificate of Amendment became effective upon filing.

***April 2024 Purchase Agreement***

On April 5, 2024, the Company closed a registered direct offering of 666,667 shares of its common stock and warrants to purchase up to an aggregate of 666,667 additional shares of common stock, at a combined purchase price of $15.00 per share and accompanying warrant. The Company generated gross proceeds of $10,000 and net proceeds of $9,125, after deducting underwriting discounts and commissions and other offering expenses.

***At-The-Market Equity Offering***

On July 2, 2020, the Company entered into an At-The-Market Sales Agreement (the "Sales Agreement") with BTIG, LLC ("BTIG"), pursuant to which the Company may offer and sell, from time to time, through BTIG, as sales agent and/or principal, shares of its common stock having an aggregate offering price of up to $50,000, subject to certain limitations on the amount of common stock that may be offered and sold by the Company set forth in the Sales Agreement. BTIG will be paid a 3% commission on the gross proceeds from each sale. The Company may terminate the Sales Agreement at any time; BTIG may terminate the Sales Agreement in certain limited circumstances. The Company did not sell any shares under the Sales Agreement during the six months ended June 30, 2025. During the six months ended June 30, 2024, the Company sold 4,366 shares of its common stock generating net proceeds of $54. As of June 30, 2025, the Sales Agreement's available capacity is $44,191.

As of the filing of this Form 10-Q, the Company is subject to the General Instruction I.B.6 to Form S-3, known as the "baby shelf rules," which limit the number of securities it can sell under the Sales Agreement and its registration statement on Form S-3.

**Preferred Stock**

On February 13, 2025, the Company entered into a Securities Purchase Agreement (the "Purchase Agreement") with certain investors (the "Purchasers"), pursuant to which the Company sold, in a private placement (the "Offering"), an aggregate of 3,300 shares of the Company's Series C Convertible Preferred Stock, par value $0.0001 per share (the "Preferred Stock"), initially convertible into up to 5,631,404 shares of the Company's common stock with a stated value of $1,000 per share (the "Stated Value"), and warrants (the "Warrants") to purchase up to an aggregate of 200% of the shares of Common Stock into which the shares of Preferred Stock are initially convertible, or 11,262,808 shares of Common Stock, for an offering price of $1,000 per share of Preferred Stock and accompanying Warrants in two equal tranches, the second of which closed on April 8, 2025.

Pursuant to the Purchase Agreement, on February 13, 2025, the Company issued and sold in an initial closing of the Offering (the "Initial Closing"), 1,650 shares of Preferred Stock, initially convertible into up to 2,815,702 shares of Common Stock, and accompanying Warrants, initially exercisable for up to 5,631,404 shares of Common Stock, for gross proceeds to the Company of $1.65 million. On April 4, 2025, the Company obtained shareholder approval ("Shareholder Approval") for the issuance of the Preferred Stock and Warrants, as required by the rules and regulations of NYSE American LLC (the " NYSE"), including Section 713 of the NYSE American Company Guide, and issued and sold, in a second closing of the Offering (the "Second Closing"), an additional 1,650 shares of Preferred Stock, initially convertible into up to 2,815,702 shares of Common Stock, and accompanying Warrants, initially exercisable for up to 5,631,404 shares of Common Stock, for gross proceeds to the Company of $1.65 million.

Under the terms of the Purchase Agreement, the Company is prohibited, subject to certain exceptions, from issuing, entering into any agreement to issue, or announcing the issuance or proposed issuance of any shares of common stock or common stock equivalents until November 2025.

**Warrants**

On April 5, 2024, the Company issued warrants to purchase 666,667 shares of the Company's common stock at an exercise price of $17.50 per share.

On February 13, 2025, the Company issued the Warrants to purchase 5,631,404 shares of the Company's common stock in the Initial Closing. Warrants to purchase an additional 5,631,404 shares of the Company's common stock were issued on April 8, 2025, in the Second Closing. The exercise price is $0.64 per share, subject to adjustment in accordance with the terms of the Warrants agreement. The Warrants expire on April 4, 2030. The Warrants include anti-dilution protection provisions. The Company determined that the Warrants did not satisfy the conditions to be accounted for as equity instruments as the Warrants were not considered indexed to the Company's own stock and were classified as a liability upon issuance. The Warrants were recorded at fair value with changes in fair value recognized in the Company's condensed consolidated statements of operations and comprehensive loss. The valuation of the Warrants was considered under Level 3 of the fair value hierarchy due to the need to use assumptions in the valuation that were both significant to the fair value measurement and unobservable (see Note 5). On June 26, 2025, the terms of the Warrants were amended to remove the provision that provided for a potential adjustment to the Warrants that did not meet the indexation requirements. As a result of the amendment, the Company determined that the Warrants satisfy the conditions to be accounted for as equity instruments and the fair value of the Warrants was reclassified to equity. There will be no subsequent measurement for the equity classified Warrants as long as the indexation and equity classification criteria continue to be met.

The following table summarizes the changes in warrants outstanding for the six months ended June 30, 2025:

---

**Basic and diluted net loss per common share**

The Company had two classes of stock outstanding during the six months ended June 30, 2025, common stock and preferred stock, and had only common stock outstanding during the six months ended June 30, 2024. The Company computes net loss per share using the two-class method, as the Preferred Stock participates in distributions with the Company's common stock. The two-class method of computing net loss per share is an earnings allocation formula that determines net loss for common stock and any participating securities according to dividends declared and participation rights in undistributed earnings.

Under the two-class method, basic net loss per share attributable to common stockholders is computed by dividing the net income attributable to common stockholders by the weighted-average number of shares of common stock outstanding during the period. Diluted net loss per share attributable to common stockholders is computed using the more dilutive of (1) the two-class method or (2) the if-converted method.

During the three and six months ended June 30, 2025 and 2024, diluted loss per common share is the same as basic loss per common share because, as the Company incurred a net loss during each period presented, the potentially dilutive securities from the assumed exercise of all outstanding stock options, warrants and preferred stock, would have an anti-dilutive effect. The following outstanding shares of potentially dilutive securities were excluded from the computation of diluted net loss per share because including them would have been anti-dilutive as of June 30, 2025 and 2024:

---

| | | |
|:---|:---|:---|
|  | **As of June 30,** | **As of June 30,** |
|  | **2025** | **2024** |
| Stock options | 464297 | 920631 |
| Convertible preferred stock upon conversion | 5631404 |  |
| Warrants | 11929475 | 666667 |
| Total | 18025176 | 1587298 |

**Note 10 – Stock-based Compensation**

*2013 Plan*

 

The Company's Amended and Restated 2013 Equity Compensation Plan (the "2013 Plan"), which expired on May 7, 2024, provided for the granting of incentive stock options, nonqualified stock options, restricted stock units, performance units, and stock purchase rights.

**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 together with our financial statements and the related notes and the other financial information included elsewhere in this Quarterly Report on Form 10-Q. This discussion contains forward-looking statements that involve risks and uncertainties. Our actual results could differ materially from those anticipated in these forward-looking statements as a result of various factors, including those discussed below and elsewhere in this Quarterly Report on Form 10-Q, in our Annual Report on Form 10-K for the year ended December 31, 2024 and in other reports we file with the Securities and Exchange Commission, particularly those under "Risk Factors." Dollars in tabular format are presented in thousands, except per share data, or as otherwise indicated.*

**CAUTIONARY NOTE REGARDING FORWARD-LOOKING STATEMENTS**

This report on Form 10-Q contains forward-looking statements made pursuant to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 under Section 27A of the Securities Act and Section 21E of the Securities Exchange Act of 1934, as amended (the "Exchange Act"). Forward-looking statements include statements with respect to our beliefs, plans, objectives, goals, expectations, anticipations, assumptions, estimates, intentions and future performance, and involve known and unknown risks, uncertainties and other factors, which may be beyond our control, and which may cause our actual results, performance or achievements to be materially different from future results, performance or achievements expressed or implied by such forward-looking statements. All statements other than statements of historical fact are statements that could be forward-looking statements. You can identify these forward-looking statements through our use of words such as "may," "can," "anticipate," "assume," "should," "indicate," "would," "believe," "contemplate," "expect," "seek," "estimate," "continue," "plan," "point to," "project," "predict," "could," "intend," "target," "potential" and other similar words and expressions of the future.

There are a number of important factors that could cause the actual results to differ materially from those expressed in any forward-looking statement made by us. These factors include, but are not limited to:

● our ability to complete
 one or more strategic transactions that will maximize our assets or otherwise provide value to stockholders;

● our ability to raise capital
 when needed;

● our ability to maintain
 or protect the validity of our patents and other intellectual property; and

● the factors listed under
 the heading "Risk Factors" in our Annual Report on Form 10-K for the year ended December 31, 2024, elsewhere in this
 report and other reports that we file with the Securities and Exchange Commission.

All forward-looking statements are expressly qualified in their entirety by this cautionary notice. You are cautioned not to place undue reliance on any forward-looking statements, which speak only as of the date of this report or the date of the document incorporated by reference into this report. We have no obligation, and expressly disclaim any obligation, to update, revise or correct any of the forward- looking statements, whether as a result of new information, future events or otherwise. We have expressed our expectations, beliefs and projections in good faith, and we believe they have a reasonable basis. However, we cannot assure you that our expectations, beliefs or projections will result or be achieved or accomplished.

**Overview**

We are a clinical-stage biopharmaceutical company focused on delivering groundbreaking therapies using our lipid nanocrystal (LNC) platform delivery technology (LNC Platform).

Key elements of our strategy now include:

● Securing one or more partners
 to monetize the value of MAT2203 in the short term and raise additional non-dilutive capital through the licensing or sale of our
 lead LNC Platform product candidate. A partnership would likely seek to advance MAT2203 into Phase 3 development as quickly as possible,
 which could position a partner to commercialize MAT2203 upon approval and which could bring additional longer-term value to the Company
 and its shareholders.

● Conserving our cash resources
 while identifying and evaluating other strategic options for the Company, which could include the in-license of one or more assets
 or seeking a merger partner for the Company.

For the six month periods ended June 30, 2025 and 2024, our net loss was $6,901 and $11,543, respectively. We have incurred losses for each period from our inception and expect to incur additional losses for the foreseeable future. We will seek to fund our operations through public or private equity offerings, debt financing, government or other third-party funding, collaborations and licensing arrangements. Adequate additional financing may not be available to us on acceptable terms, or at all. Our failure to raise capital as and when needed would impact our going concern and would have a negative impact on our financial condition and our ability to pursue our business strategy and continue as a going concern. We will need to generate significant revenues to achieve profitability, and we may never do so.

Research and development expenses consist of costs incurred for the development of product candidate MAT2203 and advancement of our LNC platform, which include:

● the cost of acquiring,
 developing, and manufacturing pre-clinical and human clinical trial materials;

● costs for consultants and
 contractors associated with Chemistry and Manufacturing Controls (CMC), pre-clinical and clinical activities and regulatory operations;

● expenses incurred under
 agreements with contract research organizations, or CROs, including the NIH, that conduct our pre-clinical or clinical trials; and

● employee-related expenses,
 including salaries and stock-based compensation expense for those employees involved in the research and development process.

Research and development activities are central to our business model. We expect our research and development expenses to increase over time because product candidates in later stages of clinical development generally have higher development costs than those in earlier stages of clinical development, primarily due to the increased size and duration of later-stage human trials. However, we anticipate that our research and development expenses during 2025 will be lower compared with expenses incurred during 2024 until such time, if at all, as we are able to secure additional funding to support initiation of our Phase 3 registration trial for MAT2203 and advancement of our LNC platform delivery technology.

***General and Administrative Expenses***

General and administrative expense for the three and six months ended June 30, 2025 were $1,837 and $3,698, respectively, and the three and six months ended June 30, 2024 were $2,468 and $4,925, respectively. General and administrative expenses consist principally of salaries and related costs for personnel in executive and finance functions. Other general and administrative expenses include facility costs, insurance, investor relations expenses, professional fees for legal, patent review, consulting and accounting/audit services. We anticipate that our general and administrative expenses during 2025 will decrease slightly compared to expenses incurred during 2024 as a result of cost-cutting measures implemented to conserve cash.

***Change in fair value of warrant liability***

In a series of transactions on February 13, 2025, and April 8, 2025, the Company closed a private placement investment with certain investors in which the investors received shares of Series C Preferred Stock and Warrants to purchase shares the Company's common stock. The Warrants were initially classified as a liability upon each issuance date with the fair value estimated using a Monte Carlo simulation model. The terms of the Warrants were amended after issuance enabling for reclassification of the Warrants as equity. Changes in fair value between the dates of issuance and the date of amendment were recognized in other (expense)/income, net at each reporting period.

A loss of $3,161 was recognized for the six months ended June 30, 2025, representing the change in fair value of the warrant liability between the issuance dates of February 13, 2025 and April 8, 2025 and the amendment date of June 26, 2025.

***Gain on sale of assets, net***

During the six months ended June 30, 2025, the company sold equipment with a net book value of $210. Proceeds from the sale were $320, resulting in a gain of $110.

***Other (expense)/income, net***

Other (expense)/income, net for the six months ended June 30, 2025 and 2024 were ($67) and $199, respectively. Other (expense)/income, net decreased compared to the prior period primarily due to recording issuance costs of $251 in connection with the Company's private placement of Series C Preferred Stock and warrants.

**Application of Critical Accounting Policies and Accounting Estimates**

A critical accounting policy is one that is both important to the portrayal of our financial condition and results of operations and requires management's most difficult, subjective or complex judgments, often as a result of the need to make estimates about the effect of matters that are inherently uncertain.

For a description of our significant accounting policies, refer to "Note 3 – *Summary of Significant Accounting Policies*" in our 2024 Form 10-K. Of these policies, the following are considered critical to an understanding of our Unaudited Condensed Consolidated Financial Statements as they require the application of the most difficult, subjective and complex judgments: (i) Other intangible assets, and (ii) Warrants.

*Warrants*

We account for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant's specific terms and applicable authoritative guidance in ASC 480, Distinguishing Liabilities from Equity and ASC 815, Derivatives and Hedging. Warrants classified as equity are recorded at fair value as of the date of issuance on our condensed consolidated balance sheets and no further adjustments to their valuation are made. Warrants that require separate accounting as liabilities are recorded on our condensed consolidated balance sheets at their fair value on the date of issuance and are revalued on each subsequent balance sheet date until such instruments are exercised or expire, with any changes in the fair value between reporting periods recorded on the condensed consolidated statement of operations. The assessment of whether the warrants are accounted for as equity-classified or liability-classified instruments is re-evaluated on a periodic basis. See Note 9 - *Stockholders' Equity* for a discussion on the Company's warrants.

**Recent Accounting Pronouncements**

Refer to "Note 3 – *Summary of Significant Accounting Policies"* in the Notes to Unaudited Condensed Consolidated Financial Statements for a discussion of recently adopted accounting pronouncements and their expected impact on our financial positions and results of operations.

**Current Operating Trends**

Our current R&D efforts are focused on advancing our lead LNC product candidate, MAT2203. Our R&D expenses consist of fees paid to consultants for work related to clinical trial design and regulatory activities, fees paid to providers for conducting various clinical studies as well as for the analysis of the results of such studies, and for other medical research addressing the potential efficacy and safety of our drugs. We believe that significant investment in product development is a competitive necessity, and we are seeking a partner to assist us in continuing to make these investments to be in a position to realize the potential of our product candidates and proprietary technologies.

We expect that most of our R&D expenses in the near-term, if any, will be incurred in support of MAT2203 and positioning that drug for a partnership with a well-funded and experienced third party biotech or pharmaceutical company.

**Results of Operations**

*Comparison of the three months ended June 30, 2025 to the three months ended June 30, 2024*

The following tables summarize our revenues and operating expenses for the periods presented:

---

| | | |
|:---|:---|:---|
|  | **Three Months Ended June 30,** | **Three Months Ended June 30,** |
|  | **2025** | **2024** |
| **Expenses:** |  |  |
| Research and development | $— | $3371 |

***Research and Development expenses.*** Research and Development (R&D) expense for the three months ended June 30, 2025 and 2024 were $0 and $3,371, respectively. The decrease in R&D expenses were primarily attributable to the decrease in clinical trial consulting costs related to the pause of our MAT2203 development program and in headcount costs resulting from our reduction in force.

***General and Administrative expenses.*** General and Administrative (G&A) expense for the three months ended June 30, 2025 and 2024 was $1,837 and $2,468, respectively. The decrease in G&A expenses were primarily attributable to lower stock based compensation expense and decreased headcount partially offset by increased legal and consulting fees.

*Comparison of the six months ended June 30, 2025 to the six months ended June 30, 2024*

The following tables summarize our revenues and operating expenses for the periods presented:

---

***Research and Development expenses.*** Research and Development (R&D) expense for the six months ended June 30, 2025 and 2024 were $85 and $6,817, respectively. The decrease in R&D expenses were primarily attributable to the decrease in clinical trial consulting costs related to the pause of our MAT2203 development program and in headcount costs resulting from our reduction in force.

***General and Administrative expenses.*** General and Administrative (G&A) expense for the six months ended June 30, 2025 and 2024 was $3,698 and $4,925, respectively. The decrease in G&A expenses were primarily attributable to lower stock based compensation expense and decreased headcount partially offset by increased legal and consulting fees.

**Liquidity and capital resources**

***Sources of Liquidity***

We have funded our operations since inception primarily through private placements of our preferred stock and our common stock and common stock warrants. As of June 30, 2025, we have raised a total of $170,207 in gross proceeds and $156,465, net, from sales of our equity securities.

As of June 30, 2025, we had cash and cash equivalents, excluding restricted cash, totaling $6,525.

***2025 Private Placement***

On February 13, 2025, we entered into a Securities Purchase Agreement (the "Purchase Agreement") with certain investors (the "Purchasers"), pursuant to which we agreed to issue and sell, in a private placement (the "Offering"), an aggregate of 3,300 shares of our Series C Convertible Preferred Stock, par value $0.0001 per share (the "Preferred Stock"), initially convertible into up to 5,631,404 shares of our common stock, par value $0.0001 per share (the "Common Stock"), with a stated value of $1,000 per share (the "Stated Value"), and warrants (the "Warrants") to purchase up to an aggregate of 200% of the shares of Common Stock into which the shares of Preferred Stock are initially convertible, or 11,262,808 shares of Common Stock, for an offering price of $1,000 per share of Preferred Stock and accompanying Warrants. The Purchase Agreement contains customary representations, warranties and agreements by us and customary conditions to closing.

Pursuant to the Purchase Agreement, on February 13, 2025, we issued and sold in an initial closing of the Offering 1,650 shares of Preferred Stock, initially convertible into up to 2,815,702 shares of Common Stock, and accompanying Warrants, initially exercisable for up to 5,631,404 shares of Common Stock, for gross proceeds of $1.65 million. On April 4, 2025, we obtained shareholder approval for the issuance of the Preferred Stock and Warrants, as required by the rules and regulations of NYSE American LLC, including Section 713 of the NYSE American Company Guide, and issued and sold, in a second closing of the Offering, an additional 1,650 shares of Preferred Stock, initially convertible into up to 2,815,702 shares of Common Stock, and accompanying Warrants, initially exercisable for up to 5,631,404 shares of Common Stock, for gross proceeds of $1.65 million.

Under the terms of the Securities Purchase Agreement, we are prohibited, subject to certain exceptions, from issuing, entering into any agreement to issue, or announcing the issuance or proposed issuance of any shares of common stock or common stock equivalents until November 2025.

***2024 Registered Direct Offering***

On April 5, 2024, the Company closed a registered direct offering of 666,667 shares of its common stock and warrants to purchase up to an aggregate of 666,667 additional shares of common stock, at a combined purchase price of $15.00 per share and accompanying warrant. The Company generated gross proceeds of approximately $10,000 and net proceeds of approximately $9,125, after deducting underwriting discounts and commissions and other offering expenses.

***2020 At-The-Market Sales Agreement***

On July 2, 2020, we entered into an At-The-Market Sales Agreement (the "Sales Agreement") with BTIG, LLC ("BTIG"), pursuant to which we may offer and sell, from time to time, through BTIG, as sales agent and/or principal, shares of our common stock having an aggregate offering price of up to $50 million, subject to certain limitations on the amount of common stock that may be offered and sold by us set forth in the Sales Agreement. BTIG will be paid a 3% commission on the gross proceeds from each sale. We may terminate the Sales Agreement at any time; BTIG may terminate the Sales Agreement in certain limited circumstances. The Company did not sell any shares under the sales agreement during the six months ended June 30, 2025. During the six months ended June 30, 2024, the Company sold 4 shares of its common stock generating net proceeds of $54. As of June 30, 2025, the Sales Agreement's available capacity is $44,191.

***Cash Flows***

The following table sets forth the primary sources and uses of cash, cash equivalents and restricted cash for each of the periods set forth below:

---

| | | |
|:---|:---|:---|
|  | **Six Months Ended June 30,** | **Six Months Ended June 30,** |
|  | **2025** | **2024** |
| Cash used in operating activities | $(4028) | $(8875) |
| Cash used in investing activities |  | (938) |
| Cash provided by financing activities | 3269 | 9242 |
| Net decrease in cash and cash equivalents and restricted cash | $(759) | $(571) |

---

***Operating Activities***

Net cash used in operating activities was $4,028 and $8,875 for the six month periods ended June 30, 2025 and 2024, respectively. Net losses of $6,901 and $11,543 for the six month periods ended June 30, 2025 and 2024, respectively, were partially offset by working capital adjustments due to the timing of receipts and payments in the ordinary course of business, adjustments for non-cash stock based compensation expense and change in fair value of the warrant liability.

***Investing Activities***

Net cash used in investing activities was $0 and $938 for the six month periods ended June 30, 2025 and 2024, respectively. The decrease of cash used in investing activities was primarily due to a $7,938 decrease purchase of marketable securities offset by a $7,000 decrease in maturities of marketable debt securities.

***Financing Activities***

Net cash provided by financing activities was $3,269 and $9,242 for the six month periods ended June 30, 2025 and 2024, respectively. The decrease in cash provided by financing activities is primarily due to the net proceeds from the sale of our Series C preferred stock of $3,020 during the six months ended June 30, 2025, being less than the net proceeds from the registered direct sale of our common stock of $9,250 during the six months ended June 30, 2024.

***Funding Requirements and Other Liquidity Matters***

We expect to continue to incur significant expenses and operating losses for the foreseeable future. We anticipate that our expenses will increase substantially if and as we:

● conduct further preclinical
 and clinical studies of MAT2203, our lead product candidate, even if such studies are primarily financed with non-dilutive funding
 from the NIH;

● seek to discover and develop
 additional product candidates;

● seek regulatory approvals
 for any product candidates that successfully complete clinical trials;

● require the manufacture
 of larger quantities of product candidates for clinical development and potentially commercialization;

● maintain, expand and protect
 our intellectual property portfolio;

● hire additional clinical,
 quality control and scientific personnel; and

● add operational, financial
 and management information systems and personnel, including personnel to support our product development and planned future commercialization
 efforts and personnel and infrastructure necessary to help us comply with our obligations as a public company.

We do not believe that our existing cash and cash equivalents will be sufficient to fund our operating expenses and capital expenditures requirements beyond the next twelve months from the filing date of this Quarterly Report. As a result, substantial doubt exists about the Company's ability to continue as a going concern.

Until such time, if ever, that we can generate revenues sufficient to achieve profitability, we expect to finance our cash needs through a combination of private and public equity offerings, debt financings, government or other third-party funding, collaborations, and licensing arrangements. To the extent that we raise additional capital through the sale of common stock, convertible securities or other equity securities, the ownership interest of our stockholders may be materially diluted, and the terms of these securities may include liquidation or other preferences that adversely affect your rights of our common stockholders. Debt financing and preferred equity financing, if available, would result in increased fixed payment obligations and may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures, or declaring dividends, that could adversely impact our ability to conduct our business. Securing additional financing could require a substantial amount of time and attention from our management and may divert a disproportionate amount of their attention away from day-to-day activities, which may adversely affect our management's ability to secure one or more partners to monetize the value of MAT2203 or future product candidates. Moreover, under the terms of a recent financing, we are prohibited, subject to certain exceptions, from issuing, entering into any agreement to issue, or announcing the issuance or proposed issuance of any shares of common stock or common stock equivalents until November 2025.

If we raise additional funds through collaborations, strategic alliances or marketing, distribution, or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or product candidates or grant licenses on terms that may not be favorable to us.

Our financial condition and results of operations may also be impacted by other factors we may not be able to control, such as global supply chain disruptions, global trade disputes and/or political instability. Increases in interest rates, especially if coupled with reduced government spending and volatility in financial markets, may have the effect of further increasing economic uncertainty and heightening these risks. Additionally, rising inflation rates may affect us by increasing operating expenses, such as employee-related costs and clinical trial expenses, negatively impacting our results of operations.

***Off-Balance Sheet Arrangements***

We did not have during the periods presented, and we do not currently have, any off-balance sheet arrangements, as defined under SEC rules, such as relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating financing transactions that are not required to be reflected on our balance sheets.

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

Not applicable.

**Item 4. CONTROLS AND PROCEDURES.**

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

***Disclosure Controls and Procedures:***

As of June 30, 2025, under the supervision and with the participation of our principal executive officer and principal financial officer we have evaluated, the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on that evaluation, our principal executive officer and principal financial officer concluded that because remediation of the deficiency in internal control over financial reporting described in our Annual Report on Form 10-K for the year ended December 31, 2024 has not been completed as described below, our disclosure controls and procedures were not effective at the reasonable assurance level as of June 30, 2025.

Our disclosure controls and procedures are designed to provide reasonable assurance that information required to be disclosed in the reports that we filed or submitted under the Exchange Act is recorded, processed, summarized and reported within time periods specified by the SEC's rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed under the Exchange Act is accumulated and communicated to our management, including principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

***Management's Report on Internal Control over Financial Reporting:***

Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Internal control over financial reporting is a process designed by, or under the supervision of, our principal executive officer and principal financial officer to provide reasonable assurance regarding the reliability of financial reporting and the preparation of consolidated financial statements for external purposes in accordance with generally accepted accounting principles. Our control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that in reasonable detail accurately and fairly reflect the transactions and dispositions of our assets; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that our receipts and expenditures are being made only in accordance with authorizations of our management and directors; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the consolidated financial statements.

Because of inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, any projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with policies and procedures may deteriorate.

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the annual or interim consolidated financial statements will not be prevented or detected on a timely basis.

As previously disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024, an evaluation was conducted under the supervision and with the participation of management, including our CEO and CFO, on the effectiveness of the Company's internal control over financial reporting as of December 31, 2024 based on criteria related to internal control over financial reporting described in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (COSO 2013 Framework). Based on this evaluation, management determined that because of the material weaknesses described below, the Company's internal control over financial reporting was not effective as of December 31, 2024.

We did not maintain an effective internal control environment to ensure the processing of and reporting of non-routine transactions are complete, accurate and timely, including the Company's indefinite-lived assets impairment assessment.

The material weakness identified above could result in a misstatement to the aforementioned asset balances and disclosures that would result in a material misstatement to the annual or interim consolidated financial statements that would not be prevented or detected on a timely basis.

***Remediation Plan:***

Management has initiated a remediation plan to address the control deficiency that led to the material weakness. The remediation plan includes, but is not limited to, engagement of additional external accounting resources to assist with the preparation and review of the Company's non-routine transactions.

***Changes in Internal Control Over Financial Reporting***

Except for changes being implemented by the Company to address the material weakness identified above, there were no changes in our internal control over financial reporting during the second quarter of 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.**

None.

**Item 1A. RISK FACTORS.**

Except as set forth below, there were no material changes from the risk factors set forth under Part I, Item 1A., "Risk Factors" in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. You should carefully consider the risk factors contained in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024 in addition to the other information set forth in this report which could materially affect our business, financial condition or future results. The risks and uncertainties described in this report and in our Annual Report on Form 10-K for the year ended December 31, 2024, as well as other reports and statements that we file with the SEC, are not the only risks and uncertainties facing us. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial may also have a material adverse effect on our financial position, results of operations or cash flows.

**Item 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS.**

On February 13, 2025 and April 8, 2025, pursuant to the Purchase Agreement, the Company sold to the Purchasers, in two equal tranches, an aggregate of 3,300 shares of Preferred Stock, initially convertible into up to 5,631,404 shares of Common Stock, and accompanying Warrants, initially exercisable for up to 11,262,808 shares of Common Stock, for gross proceeds to the Company of an aggregate of $3.3 million. The shares of Preferred Stock and Warrants were sold without registration under the Securities Ac, or state securities laws in reliance on the exemption provided by Section 4(a)(2) of the Securities Act and/or Regulation D promulgated thereunder and in reliance on similar exemptions under applicable state laws. The Company registered the shares of Common Stock underlying the Preferred Stock and Warrants on a Form S-3 Registration Statement, filed with the Securities and Exchange Commission on April 22, 2025, and declared effective on April 29, 2025.

**Item 3. DEFAULTS UPON SENIOR SECURITIES.**

None.

**Item 4. MINE SAFETY DISCLOSURES.**

Not applicable.

**Item 5. OTHER INFORMATION.**

*Rule 10b5-1 Trading Arrangements and Non-Rule 10b5-1 Trading Arrangements*

During the fiscal quarter ended June 30, 2025, none of our officers or directors, as those terms are defined in Rule 16a-1(f), adopted or terminated a "Rule 10b5-1 trading arrangement" or a "non-Rule 10b5-1 trading arrangement," as those terms are defined in Item 408 of Regulation S-K.
