ITEM 7. 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 related notes appearing elsewhere in this Annual Report on Form 10-K. Some of the information contained in this discussion and analysis or set forth elsewhere in this Annual Report on Form 10-K, including information with respect to our plans and strategy for our business and financing needs, includes forward-looking statements that involve risks and uncertainties and should be read together with the “Risk Factors” section of this Annual Report on Form 10-K for a discussion of important factors that could cause actual results to differ materially from the results described in or implied by the forward-looking statements contained in the following discussion and analysis. 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 Annual Report and in other reports we file with the Securities and Exchange Commission, particularly those under “Risk Factors.”

Overview

Intensity Therapeutics, Inc. is a late-stage clinical biotechnology company passionately committed to applying scientific leadership in the field of localized cancer reduction leading to anti-cancer immune activation. Our new approach involves the direct injection into tumors of a unique product created from our DfuseRxSM discovery platform.

IT treatment, or treatment designed to contain a drug inside a tumor without spreading to the rest of the body, has been an objective of clinicians since discovery of chemotherapeutic agents. The challenge with IT treatment approaches is

that a tumor’s lipophilic, high fat, dense and pressurized microenvironment is incompatible with and does not absorb water-based products. We believe that this drug delivery challenge limits the effectiveness of prior and current IT treatments, which involve injecting aqueous drugs into a tumor without sufficient consideration of the tumor environment (regardless of the drug’s mechanism or approach, i.e. the stimulation of an inflammatory response or efforts to attract immune cells into a hostile live tumor). Accordingly, there remains a continued unmet need for the development of direct IT therapies for solid tumors that provide high local killing efficacy coupled with nontoxic systemic anti-cancer effects. We believe we have created a product candidate, using our non-covalent conjugation chemistry, with the necessary physical properties to overcome this local delivery challenge. Evidence shows the mechanism of tumor killing achieved by our drug candidate also leads to systemic immune activation and T-cell repertoire expansion in certain cancers.

Our platform creates patented anti-cancer product candidates comprising active anti-cancer agents and amphiphilic molecules. Amphiphilic molecules have two distinct components: one part is soluble in water and the other is soluble in fat or oils. When an amphiphilic compound is mixed with therapeutic agents, such as chemotherapies, the agents also become soluble in both fat and water. Our product candidates include novel formulations consisting of potent anti-cancer drugs mixed together with these amphiphilic agents.

Our lead product candidate, INT230-6, is primarily comprised of three components: (i) cisplatin, a proven anti-cancer cytotoxic agent, (ii) vinblastine sulfate, also a proven anti-cancer cytotoxic agent, and (iii) SHAO which enables the two cytotoxic agents to disperse through a tumor and diffuse into cancer cells following a direct intratumoral injection. These three components are mixed and combined into one vial at a fixed ratio. Cisplatin and vinblastine sulfate are both generic and available to purchase in bulk supply commercially. The FDA has approved both drugs as intravenous agents for several types of cancers. Cisplatin was first approved in 1978 for testicular cancer, and is also approved in ovarian and bladder cancer. The drug is also used widely in several other cancers including pancreatic and bile duct cancer. Vinblastine sulfate was first approved in 1965 and is also approved in generalized Hodgkin’s disease, lymphocytic lymphoma, advanced carcinoma of the testis, and certain types of sarcomas. The drug is also used in breast and lung cancer.

Our Clinical Programs

In 2017, we initiated the IT-01 Study, a Phase 1/2 dose escalation study using INT230-6 in the United States under an IND authorized by the FDA and in Canada under a CTA approved by Health Canada. The study tested the safety and efficacy of INT230-6 in patients with refractory or metastatic cancers, and enrolled 110 patients in three arms: (i) INT230-6 used as a monotherapy, (ii) INT230-6 in combination with Merck’s Keytruda® (pembrolizumab), and (iii) INT230-6 in combination with BMS’s Yervoy® (ipilimumab). We completed enrollment of the IT-01 Study in June 2022, locked the IT-01 Study database in February 2023 and finalized the clinical study report in September 2023. We delivered the combination-specific reports and other information to our partners in the fourth quarter of 2023.

In 2021, we initiated the INVINCIBLE-2 Study, a Phase 2 randomized study that tested INT230-6 as a monotherapy treatment in early-stage breast cancer for patients not suitable for presurgical chemotherapy. The study enrolled 91 subjects and the database was locked in November 2023. The key endpoint was whether INT230-6 could reduce a patient’s cancer compared to no treatment, which is the current SOC for the majority of patients with early-stage breast cancer, or a saline injection. Substantial reduction of cancer presurgically in aggressive forms of cancer has been shown to correlate with delaying disease recurrence. The key endpoints of the INVINCIBLE 2 Study were to understand the percentage of necrosis that can be achieved in tumors of varying sizes for a given dose, especially for tumors larger than 2 centimeters in longest diameter. We also sought to determine whether a local or whole-body anti-cancer immune response could be induced. The INVINCIBLE-2 Study demonstrated a high order of necrosis in presurgical breast cancer tumors in the period from diagnosis to surgery, with some patients experiencing greater than 95% necrosis of the tumor. Data from the INVINCIBLE-2 Study demonstrated that INT230-6 had a favorable safety profile. There was also an increase of certain types of immune cells (CD4+ and NK T-cells) in the tumor and blood. Additionally, there was an increase in the T-cells repertoire relative to control.

In July 2024, we initiated and dosed our first patient in the INVINCIBLE-3 Study, a Phase 3 open-label, randomized study testing INT230-6 as a monotherapy compared to the SOC drugs in second-and third-line treatment for certain soft tissue sarcoma subtypes. This 333-patient study with an endpoint of overall survival has been authorized by the FDA, Health Canada, the European Medicines Authority, and Australia's Therapeutic Goods Administration. In March 2025, we paused new site activations and patient enrollments due to funding constraints. Prior to this pause, the trial had enrolled 21 patients. We will continue to treat all patients enrolled in this study in cooperation with our third-party contract research organizations to reduce ongoing costs during this pause. Once sufficient funding is obtained, we plan to restart site activations and patient enrollment in the INVINCIBLE-3 Study.

In October 2024, in collaboration with the Swiss Cancer Group, formerly the Swiss Cancer Group for Clinical Cancer Research (SAKK), we initiated and dosed our first patient in the INVINCIBLE-4 Study, a Phase 2 study to treat

Table of Contents

patients with localized TNBC. The endpoint is the change in the pathological complete response rate for the combination compared to the SOC alone. In September 2025, we paused new patient enrollment to revise the dosing regimen for patients receiving INT230-6 in Cohort A due to some patients in Cohort A experiencing localized skin irritation near the tumor site. In March 2026, a protocol amendment was submitted to the Swissmedic and the Swiss Ethics Committee to use a lower drug volume per tumor volume ratio and a single injection of INT230-6. Full approval to resume enrollment was granted on March 26, 2026, and we plan to resume enrollment in the second quarter of 2026. We are currently targeting to complete enrollment by the end of 2027 and will likely add resources to help sites enroll new patients. In the event we are unable to obtain sufficient additional funding, we may have to delay the completion of the INVINCIBLE-4 Study until such funding is obtained.

We have also successfully developed Phase 3 quality analytical methods for the three INT230-6 components and successfully manufactured a large-scale batch of INT230-6. In a meeting with the FDA in the fourth quarter of 2023, we agreed on a CMC plan for Phase 3 and product registration for our three key ingredients and INT230-6. If we successfully execute the agreed upon plan, and expect that the CMC portion of an NDA should be acceptable to the FDA for product approval and registration (subject to final NDA review).

Since our inception in 2012, our operations have included business planning, hiring personnel, raising capital, building our intellectual property portfolio, and performing both research and development on our product candidates. We have incurred net losses since inception and expect to incur net losses in the future as we continue our research and development activities. To date, we have funded our operations primarily through net proceeds received from issuances of our Common Stock, preferred stock and convertible notes. As of December 31, 2025, we had approximately $11.9 million of cash and cash equivalents. Since our inception, we have incurred significant operating losses. We incurred net losses of $11.6 million and $16.3 million for the years ended December 31, 2025 and 2024, respectively. As of December 31, 2025 and 2024, we had an accumulated deficit of approximately $78.4 million and $66.8 million, respectively.

We expect to incur significant expenses and operating losses for the next several years as we continue to:

•Fund our INVINCIBLE-3 and INVINCIBLE-4 clinical studies;

•Incur manufacturing costs for additional GMP batches of our product candidates and enhancer molecules;

•Seek regulatory approvals for any of our product candidates that successfully complete clinical trials;

•Hire additional personnel;

•Expand our operational, financial, and management systems;

•Invest in measures to protect our existing and new intellectual property; and

•Establish a sales, marketing, medical affairs, and distribution infrastructure to commercialize any product candidates for which we may obtain marketing approval and intend to commercialize.

Our ability to ultimately generate revenue to achieve profitability will depend heavily on the development, approval, and subsequent commercialization of our product candidates. If we fail to become profitable or are unable to sustain profitability on a continuing basis, then we may be unable to continue our operations at planned levels and be forced to reduce or terminate our operations.

As a result, we will need substantial additional funding to support our continuing operations and pursue our growth strategy. Until such time as we can generate significant revenue from product sales, if ever, we expect to finance our operations through the sale of equity, debt financing, or other capital sources, which may include collaborations with other companies or other strategic transactions. We may not be able to raise additional funds or enter into such other agreements or arrangements when needed on favorable terms, or at all. If we fail to raise capital or enter into such agreements as and when needed, we would have to significantly delay, reduce, or eliminate the development and commercialization of one or more of our product candidates.

Components of Results of Operations

Revenue

To date, we have not generated any revenue from product sales and we do not expect any revenue from the sale of product in the foreseeable future. We have not generated any revenue from licensing of our technology or product candidates yet either. If our development efforts for any of our product candidates are successful and result in regulatory approval, then we may generate revenue in the future from product sales or licensing. We cannot predict if, when, or to what extent we will generate revenue from the commercialization, licensing or sale of any of our product candidates. We may never succeed in obtaining regulatory approval for any of our product candidates.

Years Ended December 31,

Operating expenses:

Years Ended December 31,

Research and development expenses:

Clinical trial expenses:

IT-01 Study (Phase 1/2 Metastatic Cancers) $ — $ (128) $ 128

Year Ended December 31, 2025 Compared to Year Ended December 31, 2024

Research and development expenses decreased $3.7 million or 35%, and were primarily due to the following:

•Clinical trial expenses decreased $2.8 million, primarily due to lower INVINCIBLE-3 Study costs. In March 2025, we paused new site activations and patient enrollments in the INVINCIBLE-3 Study, due to funding constraints. Prior to this pause, the trial had enrolled 21 patients. We will continue to treat all patients enrolled in this study in cooperation with our third-party contract research organizations during this pause, and once sufficient funding is obtained, we plan to restart site activations and patient enrollment.

Table of Contents

•Contract manufacturing costs declined by $0.6 million, as there were no new manufacturing batches of INT230-6 in 2025.

•Salaries and benefits related costs increased due to an estimated bonus accrual of $0.3 million in 2025 compared to zero in 2024, which was partially offset by a decrease of $0.1 million due to a minor reduction in employee headcount in 2025.

•Stock-based compensation decreased due to lower fair value per share of option awards granted to employees in 2025.

General and administrative expenses decreased $0.9 million or 15%, and were primarily due to the following:

•Salaries and benefits related costs increased due to an estimated bonus accrual of $0.5 million in 2025 compared to zero in 2024.

•Insurance decreased by $0.2 million due to the favorable directors and officers insurance renewal terms obtained in 2025 compared to the prior policy year.

•Legal, accounting, consulting and other expenses decreased as a result of cost saving from the integration of new systems and other cost-efficient activities in the administrative areas.

•Stock-based compensation decreased due to lower fair value per share of option awards granted to employees in 2025.

Interest income in 2025 and 2024 related to interest earned on cash and investment balances.

Liquidity and Capital Resources

Our financial statements have been prepared assuming we will continue as a going concern. We have incurred losses from operations and negative cash flows from operations that raise substantial doubt about our ability to continue as a going concern.

We have financed our operations primarily through an initial investment from our founder, the issuance and sale of convertible debt notes, and private and public equity financings. Since our inception, we have not generated any revenue from product sales and have incurred significant operating losses. We expect to continue to incur significant expenses and operating losses for the foreseeable future as we advance the clinical development of our product candidates. We expect that our research and development and general and administrative costs will continue to increase significantly, including in connection with conducting clinical trials for our product candidates, developing our manufacturing capabilities and building and qualifying our manufacturing facility to support clinical trials and commercialization and providing general and administrative support for our operations, including the cost associated with operating as a public company. As a result, we will need additional capital to fund our operations, which we may obtain from additional equity or debt financings, collaborations, licensing arrangements or other sources. The sale of equity and convertible debt securities may result in dilution to our stockholders. Additional capital may not be available on reasonable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we could be forced to delay, scale back or discontinue the development of our product candidates.

On March 23, 2026, we filed a prospectus supplement to adjust the maximum the Company may sell and issue under the ATM Sales Agreement to $60.0 million of our common stock, not including the shares previously sold under the ATM Sales Agreement. Since inception through March 22, 2026, we have issued 1,297,655 shares of common stock under the ATM Sales Agreement for net proceeds of $11.5 million.

On October 30, 2025, the Company entered into a Securities Purchase Agreement with an institutional investor, pursuant to which the Company issued and sold in a registered direct offering by the Company directly to the investor 200,000 shares of common stock at a price of $20.00 per share, for aggregate gross proceeds of $4.0 million before deducting the placement agent’s fees and related offering expenses.

On June 11, 2025, we entered into an underwriting agreement (the “Underwriting Agreement”) with ThinkEquity LLC (the “Underwriter”) relating to the issuance and sale of an aggregate of 267,000 shares (the “Firm Shares”) of our common stock to the Underwriter at a price to the public of $7.50 per share (the “June 2025 Offering”). Pursuant to the terms of the Underwriting Agreement, we granted to the Underwriter a 45-day option to purchase up to an additional 40,050 shares of common stock in the June 2025 Offering (the “Option Shares” and together with the Firm Shares, the “Shares”). The Underwriter exercised its option in full to purchase the 40,050 Option Shares at the public offering price on June 12, 2025.

Table of Contents

The June 2025 Offering, including the exercise of the Underwriter’s over-allotment option, closed on June 13, 2025. All of the Shares were sold by us. Pursuant to the Underwriting Agreement, we also agreed to issue to the Underwriter and/or its designees warrants to purchase up to 15,352 shares of common stock (the “Representative’s Warrants”), which equals 5% of the Shares purchased in the June 2025 Offering, such warrants to be exercisable as set forth in the Representative’s Warrant Agreement. The net proceeds from the June 2025 Offering, including the exercise of the Underwriter’s over-allotment option, were approximately $1.8 million after deducting the underwriting discounts and commissions and estimated offering expenses payable by us.

On April 24, 2025, we commenced a best efforts public offering (the “April 2025 Offering”) of an aggregate of (i) 125,333 shares (the “Shares”) of the our common stock, (ii) 125,333 Series B-1 Common Warrants (the “Series B-1 Common Warrants”) to purchase up to 125,333 shares of common stock (the “Series B-1 Common Warrant Shares”), (iii) 125,333 Series B-2 Common Warrants (the “Series B-2 Common Warrants” and together with the Series B-1 Warrants, the “Warrants”) to purchase up to 125,333 shares of common stock (the “Series B-2 Common Warrant Shares” and together with the Series B-1 Common Warrant Shares, the “Warrant Shares”). In connection with the April 2025 Offering, we entered into a Securities Purchase Agreement on April 24, 2025 with certain institutional investors participating in the April 2025 Offering. The April 2025 Offering closed on April 28, 2025. Each Share was sold together with one Series B-1 Common Warrant to purchase one share of common stock and one Series B-2 Common Warrant to purchase one share of common stock. The combined offering price for each Share and accompanying Warrants was $18.75. Each Warrant has an exercise price of $21.25 and was immediately exercisable upon issuance. The Series B-1 Common Warrants will expire on the five-year anniversary of the date of issuance, and the Series B-2 Common Warrants will expire on the eighteen-month anniversary of the date of issuance. We raised an aggregate of $2.35 million in the April 2025 Offering, and net proceeds of the April 2025 Offering, after deducting the fees and expenses were approximately $1.9 million.

On November 21, 2024, we entered into a Securities Purchase Agreement with a single healthcare focused institutional investor (the “Investor”), pursuant to which we agreed to issue and sell, in a registered direct offering directly to the Investor, 49,484 shares of common stock to the Investor, at a price of $60.625 per share, for aggregate gross proceeds of approximately $3.0 million before deducting the placement agents’ fees and related offering expenses. In a concurrent private placement, we agreed to issue to the Investor common stock warrants to purchase up to 49,484 shares (the “Common Warrants”) at an exercise price of $73.75 per share. Each Common Warrant is exercisable six months from the issuance date and will expire five and one-half years from the issuance date.

On July 3, 2024, we filed a universal shelf registration statement on Form S-3, which was declared effective by the SEC on July 11, 2024, on which we registered for sale up to $150 million of any combination of our common stock, preferred stock, debt securities, warrants, and/or units from time to time and at prices and on terms that we may determine, which included up to $15 million of common stock that we may issue and sell from time to time, through H.C. Wainwright & Co., LLC (“Wainwright”) acting as our sales agent, pursuant to the sales agreement that we entered into with Wainwright on July 3, 2024 for our “at-the-market” equity program (the “ATM Sales Agreement”).

As of December 31, 2025, our cash and cash equivalents were approximately $11.9 million. Based on our balances in cash and cash equivalents, we project to have sufficient cash to fund our current operating plan into the second quarter of 2027. Accordingly, we will need to obtain substantial additional funding to continue our operations. We cannot guarantee that future financing will be available in sufficient amounts or on terms acceptable to us, if at all.

The following table summarizes the net cash provided by (used in) operating activities and financing activities for the periods indicated (in thousands):

Years Ended December 31,

Net cash used in operating activities $ (9,233) $ (15,220)

Off-Balance Sheet Arrangements

We did not have any off-balance sheet arrangements as of December 31, 2025.

Seasonality

Our business experiences limited seasonality.

Critical Accounting Policies and Estimates

Our management’s discussion and analysis of financial condition and results of operations is based on our financial statements, which have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”). The preparation of our financial statements and related disclosures requires us to make estimates and assumptions that affect the reported amounts of assets and liabilities, costs and expenses, and the disclosure of contingent assets and liabilities in our financial statements. These items are monitored and analyzed by us for changes in facts and circumstances, and material changes in these estimates could occur in the future. We base our estimates on historical experience, known trends and events, and on various other factors that we believe are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may materially differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in the notes to our financial statements included elsewhere in this Annual Report, we believe that the following accounting policies are those most significant to the judgments and estimates used in the preparation of our financial statements.

Accrued Research and Development Expenses

Research and development costs are expensed as incurred. We record the estimated CRO, CMO, and patient care costs as services are provided but not yet invoiced and include these costs in the accrued expenses in the balance sheet and within research and development expense in the statement of operations.

Equity-Based Compensation

We recognize compensation costs related to stock option grants to employees and board members and warrant grants to nonemployees based on the estimated fair value of the awards on the date of grant. We estimate the grant date fair value and the resulting stock-based compensation expense using the Black-Scholes option-pricing model. The grant date fair

Table of Contents

value of the stock-based awards is recognized on a straight-line basis over the requisite service periods, which are generally the vesting period of the respective awards. Forfeitures are accounted for as they occur.

We historically have been a private company and lack company-specific historical and implied volatility information for our shares. Therefore, we estimate our expected share price volatility based on the historical volatility of publicly traded peer companies and expect to continue to do so until such time as we have adequate historical data regarding the volatility of our own traded share price.

Recent Accounting Pronouncements

The Financial Accounting Standards Board has issued certain accounting pronouncements as of December 31, 2025 that will become effective in subsequent periods; however, we do not believe that any of those pronouncements would have significantly affected our financial accounting measurements or disclosures had they been in effect during 2025, or that they will have a significant impact on us at the time they become effective.

JOBS Act Accounting Election

We are an “emerging growth company,” as defined in the JOBS Act. Under the JOBS Act, emerging growth companies can delay adopting new or revised accounting standards issued subsequent to the enactment of the JOBS Act until such time as those standards apply to private companies. We have irrevocably elected not to avail ourselves of this exemption from new or revised accounting standards and, therefore, will be subject to the same new or revised accounting standards as other public companies that are not emerging growth companies.

Subject to certain conditions set forth in the JOBS Act, if, as an “emerging growth company”, we choose to rely on such exemptions we may not be required to, among other things, (i) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404, (ii) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (iii) comply with any requirement that may be adopted by the PCAOB regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis), and (iv) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of the CEO’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of our IPO or until we are no longer an “emerging growth company,” whichever is earlier.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

ITEM 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures (as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act) are designed to ensure that the information required to be disclosed by us in the reports filed or submitted by us under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms and such information is accumulated and communicated to management, including the Chief Executive Officer, Chief Financial Officer, and Principal Accounting Officer, to allow timely decisions regarding required disclosure.

Table of Contents

Disclosure controls and procedures, no matter how well designed and operated, can provide only reasonable assurances of achieving the desired controls.

As of December 31, 2025, we carried out an evaluation over the effectiveness of the design and operation of our disclosure controls and procedures defined above. Based upon that evaluation, we have concluded that, as of December 31, 2025, our disclosure controls and procedures were effective at a reasonable assurance level.

Limitations on the Effectiveness of Controls

Our management recognizes that any set of controls and procedures, no matter how well-designed and operated, can provide only reasonable, not absolute, assurance of achieving the desired control objectives. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, with us have been detected. These inherent limitations include the realities that judgments in decision-making can be faulty and that breakdowns can occur because of simple error or mistake. Additionally, controls can be circumvented by the individual acts of some persons, by collusion of two or more people or by management override of controls. For these reasons, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Management’s Annual Report on Internal Control over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting for us. Internal control over financial reporting (as defined in Rule 13a-15(f) of the Exchange Act) is a process to provide reasonable assurance regarding the reliability of our financial reporting for external purposes in accordance with U.S. generally accepted accounting principles. Internal control over financial reporting includes maintaining records that in reasonable detail accurately and fairly reflect our transactions; providing reasonable assurance that transactions are recorded as necessary for preparation of our consolidated financial statements; providing reasonable assurance that receipts and expenditures of company assets are made in accordance with management authorization; and providing reasonable assurance that unauthorized acquisition, use or disposition of company assets that could have a material effect on our consolidated financial statements would be prevented or detected on a timely basis. Because of its inherent limitations, internal control over financial reporting is not intended to provide absolute assurance that a misstatement of our consolidated financial statements would be prevented or detected.

Family Relationships

There are no family relationships between any of our executive officers and directors.

Arrangements between Officers and Directors

Except as set forth herein, to our knowledge, there is no arrangement or understanding between any of our officers or directors and any other person pursuant to which the officer or director was selected to serve as an officer or director.

Involvement in Certain Legal Proceedings

Code of Business Conduct and Ethics

Our board of directors established a Code of Business Conduct and Ethics applicable to our directors, officers and employees. The Code of Business Conduct and Ethics is accessible on our website at www.intensitytherapeutics.com. If we make any substantive amendments to the Code of Business Conduct and Ethics or grant any waiver, including any implicit waiver, from a provision of the Code of Business Conduct and Ethics to our officers, we will disclose the nature of such amendment or waiver on that website or in a report on Form 8-K.

Insider Trading Policy

We have adopted insider trading policies and procedures (the “Insider Trading Policy”) that apply to our employees, directors and designated consultants. The Insider Trading Policy governs the purchase and sale or other dispositions of certain investment products and is reasonably designed to promote compliance with insider trading laws, rules and regulations. A copy of the Insider Trading Policy is attached hereto as Exhibit 19.1.

Board Composition and Election of Directors

Our business and affairs are managed under the direction of our board of directors. The primary responsibilities of our board of directors are to provide oversight, strategic guidance, counseling and direction to our management. Our board of directors meets on a regular basis and additionally as required.

The number of directors is fixed by our board of directors, subject to the terms of our amended and restated certificate of incorporation and our second amended and restated bylaws. Our board of directors consists of five (5) directors, four (4) of whom qualify as “independent” under Nasdaq listing standards.

Table of Contents

Directors are (except for the filling of vacancies and newly created directorships) elected by the holders of a plurality of the votes cast by the holders of shares present in person or represented by proxy at the meeting and entitled to vote on the election of such directors. In accordance with our amended and restated certificate of incorporation and our second amended and restated bylaws, our board of directors is divided into three classes with staggered three-year terms. Only one class of directors is elected at each annual meeting of our stockholders, with the other classes continuing for the remainder of their respective three-year terms. Our directors are divided among the three classes as follows:

•the Class I directors are Mr. Daniel Donovan and Mr. Thomas I. H. Dubin, and their terms will expire at the 2027 annual meeting of stockholders;

•the Class II director is Dr. Mark A. Goldberg, and his term will expire at the 2028 annual meeting of stockholders; and

•the Class III directors are Dr. Emer Leahy and Lewis H. Bender, and their terms will expire at the 2026 annual meeting of stockholders.

Each director’s term will continue until the election and qualification of his or her successor, or his or her earlier death, resignation or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of the directors. This classification of our board of directors may have the effect of delaying or preventing changes in control of our company.

Director Independence

Our board of directors has undertaken a review of the independence of each director. Based on information provided by each director concerning his or her background, employment and affiliations, our board of directors has determined that Mr. Daniel Donovan, Dr. Emer Leahy, Dr. Mark A. Goldberg and Mr. Thomas I. H. Dubin do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the applicable rules and regulations of the SEC and the listing standards of Nasdaq. In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with our company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director, and the transactions involving them described in the section titled “Certain Relationships and Related Party Transactions.”

Narrative Disclosure to Summary Compensation Table

Annual Base Salary

Our NEOs each receive a base salary to compensate them for services rendered to our company. The base salary payable to each named executive officer is intended to provide a fixed component of compensation reflecting the executive’s skill set, experience, role and responsibilities. Base salaries are reviewed annually, typically in connection with our annual performance review process, approved by our board of directors or the compensation committee, and may be adjusted from time to time to realign salaries with market levels after taking into account individual responsibilities, performance, and experience.

Table of Contents

For fiscal year 2025, the annual base salaries for each of Mr. Bender, Mr. Talamo, and Mr. Wesolowski were $549,150, $381,100 and $214,240 respectively. For fiscal year 2024, the annual base salaries for each of Mr. Bender, Mr. Talamo, and Mr. Wesolowski were $549,150, $370,000 and $260,000 respectively.

Equity-Based Incentive Awards

Our equity award program is the primary vehicle for offering long-term incentives to our executives. We believe that equity awards provide our executives with a strong link to our long-term performance, create an ownership culture and help to align the interests of our executives and our stockholders. The use of options also can provide tax and other advantages relative to other forms of equity compensation.

We award equity grants broadly to our employees, including to our non-executive employees. Grants to our executives, including the NEOs, and other employees are made at the discretion of our board of directors and are generally made upon commencement of employment, promotion or annually. We believe that our equity awards are an important retention tool for our NEOs, as well as for our other employees.

If he is terminated for Cause, he will not receive any severance. If there is a Change in Control (as defined below) of the Company and Mr. Talamo is terminated without Cause or resigns for Good Reason within six months following such Change in Control, then Mr. Talamo shall be entitled, subject to execution of a release, to receive a lump sum severance payment equal to (i) four months of base month salary if such termination or resignation occurs following one year of employment, (ii) five months of base month salary if such termination or resignation occurs following two years of employment, or (iii) six months of base month salary if such termination or resignation occurs following three or more years of employment.

The definitions below are applicable to the Talamo Agreement:

Termination for “Cause” is termination by the Company occasioned by actions of Mr. Talamo that are against Company policy, that are illegal or that may lead to serious repercussions for the Company, our employees or our corporate partners. Termination for “Cause” may be necessitated by a serious violation of our code of conduct, inappropriate disclosure of confidential information or trade secrets, or continuous poor performance as determined by our board of directors. “Cause” may also include dereliction of duties, poor relationships with other employees, sexual harassment, or treatment of external parties or partner companies that results in negative outcomes for the Company.

Resignation for “Good Reason” is resignation by Mr. Talamo due to a significant reduction in his responsibilities or authority as an executive, a decrease in his material benefits or compensation not due to financial distress of the Company, or relocation of Company’s current corporate offices to more than 50 miles further away from his current home.

2013 Stock and Option Plan

Under our 2013 Stock and Option Plan (the “2013 Plan”), 180,000 shares of Common Stock were reserved for issuance in the form of incentive stock options, non-qualified stock options, restricted stock, unrestricted stock, stock appreciation rights or any combination of the foregoing. The shares issuable pursuant to awards granted under the 2013 Plan are authorized but unissued shares.

The 2013 Plan is administered by our board or at the discretion of the board, which has full power to select the individuals to whom awards will be granted and to determine the specific terms and conditions of each award, subject to the provisions of the 2013 Plan. Pursuant to the 2013 Plan and subject to applicable law, our board of directors has delegated to the compensation committee the power to make recommendations to the board of directors relating to management compensation, the adoption of employee benefit plans, stock option or equity incentive plans and other similar matters.

The option exercise price of each option granted under the 2013 Plan is determined by our board of directors and may not be less than the fair market value of a share of Common Stock on the date of grant. The term of each option is fixed by the board and may not exceed 10 years from the date of grant. The board determines at what time or times each option may be exercised when granting the option.

The 2013 Plan provides that, upon the consummation of a sale event, unless provision is made in connection with the sale event for the assumption or continuation of the awards by the successor entity or substitution of the awards with new awards of the successor entity, with appropriate adjustment, the 2013 Plan and all outstanding and unexercised options issued thereunder will terminate upon the effective time of the sale event. We may make or provide for cash payment to holders of options equal to the difference between (i) the per share cash consideration in the sale event multiplied by the number of shares subject to outstanding options being cancelled, and (ii) the aggregate exercise price to the holders of all vested and exercisable options.

Our board of directors may amend the 2013 Plan but no such action may adversely affect the rights of an award holder without such holder’s consent. Approval by our stockholders of amendments to the 2013 Plan must be obtained if required by law.

The 2013 Plan terminated in August 2023 on the tenth anniversary of the 2013 Plan’s date of adoption by the board. No new awards were made under the 2013 Plan after such termination date, but awards previously granted may extend beyond such date.

2021 Stock Incentive Plan

On November 12, 2021, we adopted a new equity incentive plan, the 2021 Stock Incentive Plan (the “2021 Plan”). Under the 2021 Plan, we may grant cash and equity incentive awards to eligible service providers in order to attract, motivate and retain the talent for which we compete. The material terms of the 2021 Plan are summarized below.

Types of Awards. The 2021 Plan provides for the grant of non-qualified stock options (“NQSOs”), incentive stock options (“ISOs”), restricted stock awards, restricted stock units (“RSUs”), unrestricted stock awards, stock appreciation rights and other forms of stock-based compensation.

Eligibility and Administration. Employees, officers, consultants, directors, and other service providers of the Company and its affiliates are eligible to receive awards under the 2021 Plan. The 2021 Plan is administered by the board with respect to awards to non-employee directors and by the Compensation Committee with respect to other participants, each of which may delegate its duties and responsibilities to committees of the company’s directors and/or officers (all such bodies and delegates referred to collectively as the plan administrator), subject to certain limitations that may be imposed under Section 16 of the Exchange Act, and/or other applicable law or stock exchange rules, as applicable. The plan administrator has the authority to make all determinations and interpretations under, prescribe all forms for use with, and adopt rules for the administration of, the 2021 Plan, subject to its express terms and conditions. The plan administrator also sets the terms and conditions of all awards under the 2021 Plan, including any vesting and vesting acceleration conditions.

Table of Contents

Share Reserve. Pursuant to the 2021 Plan, we have reserved 120,000 shares of the Common Stock for issuance thereunder, which reserve shall be increased annually beginning on January 1, 2022 and ending on and including January 1, 2031, equal to the lesser of (A) 3.5% of the aggregate number of shares of Common Stock outstanding on the final day of the immediately preceding calendar year or (B) such smaller number of shares as is determined by our board. The share reserve is subject to the following adjustments:

•The share limit is increased by the number of shares subject to awards granted that later are forfeited, expire or otherwise terminate without issuance of shares, or that are settled for cash or otherwise do not result in the issuance of shares.

•Shares that are withheld upon exercise to pay the exercise price of a stock option or satisfy any tax withholding requirements are added back to the share reserve and again are available for issuance under the 2021 Plan.

Pursuant to the provisions of the 2021 Plan, the authorized shares were increased from 120,000 to 129,548 effective January 1, 2023. On January 1, 2024, pursuant to the provisions of the 2021 Plan, authorized shares increased by 19,193 shares. On January 1, 2025, pursuant to the provisions of the 2021 Plan, authorized shares increased by 21,172 shares. As of December 31, 2025, options to purchase 38,291 shares of Common Stock were available to be issued under the 2021 Plan. On January 1, 2026, pursuant to the provisions of the 2021 Plan, authorized shares increased by 88,357 shares.

Awards issued in substitution for awards previously granted by a company that merges with, or is acquired by, the Company do not reduce the share reserve limit under the 2021 Plan.

Director Compensation. The 2021 Plan provides for an annual limit on non-employee director compensation of $500,000, increased to $750,000 in the fiscal year of a non-employee director’s initial service as a non-employee member of the board of directors of the Company. This limit applies to the sum of both equity grants that could be awarded to non-employee directors during a fiscal year (based on their value under ASC Topic 718 on the grant date) and cash compensation, such as cash retainers and meeting fees earned during a fiscal year. Notwithstanding the foregoing, the board reserves the right to make an exception to these limits due to extraordinary circumstances without the participation of the affected director receiving the additional compensation.

Stock Options. ISOs may be granted only to employees of the Company, or to employees of a parent or subsidiary of the Company, determined as of the date of grant of such options. An ISO granted to a prospective employee upon the condition that such person becomes an employee shall be deemed granted effective on the date such person commences employment. The exercise price of an ISO shall not be less than 100% of the fair market value of the shares covered by the awards on the date of grant of such option or such other price as may be determined pursuant to the Internal Revenue Code of 1986, as amended from time to time (the “Code”). Notwithstanding the foregoing, an ISO may be granted with an exercise price lower than the minimum exercise price set forth above if such award is granted pursuant to an assumption or substitution for another option in a manner that complies with the provisions of Section 424(a) of the Code. Notwithstanding any other provision of the 2021 Plan to the contrary, no ISO may be granted under the 2021 Plan after 10 years from the date that the 2021 Plan was adopted. No ISO shall be exercisable after the expiration of 10 years after the effective date of grant of such award, subject to the following sentence. In the case of an ISO granted to a ten percent stockholder, (i) the exercise price shall not be less than 110% of the fair market value of a share on the date of grant of such ISO, and (ii) the exercise period shall not exceed 5 years from the effective date of grant of such ISO.

Restricted Stock and Restricted Stock Units. The committee may award restricted stock and RSUs under the 2021 Plan. Restricted stock awards consist of shares of stock that are transferred to the participant subject to restrictions that may result in forfeiture if specified vesting conditions are not satisfied. RSU awards result in the transfer of shares of stock to the participant only after specified vesting conditions are satisfied. A holder of restricted stock is treated as a current stockholder and shall be entitled to dividend and voting rights, whereas the holder of a restricted stock unit is treated as a stockholder with respect to the award only when the shares are delivered in the future. RSUs may include dividend equivalents. Specified vesting conditions may include performance goals to be achieved during any performance period and the length of the performance period. The committee may, in its discretion, make adjustments to performance goals based on certain changes in the Company’s business operations, corporate or capital structure or other circumstances. When the participant satisfies the conditions of an RSU award, the Company may settle the award (including any related dividend equivalent rights) in shares, cash or other property, as determined by the committee, in its sole discretion.

Other Shares or Share-Based Awards. The committee may grant other forms of equity-based or equity-related awards other than stock options, restricted stock or restricted stock units. The terms and conditions of each stock-based award shall be determined by the committee.

104

Table of Contents

Clawback Rights. Awards granted under the 2021 Plan will be subject to recoupment or clawback under the Company’s clawback policy or applicable law, both as in effect from time to time.

Sale of the Company. Awards granted under the 2021 Plan automatically accelerate and vest, become exercisable (with respect to stock options), or have performance targets deemed earned at target level if there is a sale of the Company. The Company does not use a “liberal” definition of change in control as defined in Institutional Shareholder Services’ proxy voting guidelines.

No Repricing. The 2021 Plan prohibits the amendment of the terms of any outstanding award, and any other action taken in a manner to achieve (i) the reduction of the exercise price of NQSOs, ISOs or stock appreciation rights (collectively, “Stock Rights”); (ii) the cancellation of outstanding Stock Rights in exchange for cash or other awards with an exercise price that is less than the exercise price or base price of the original award; (iii) the cancellation of outstanding Stock Rights with an exercise price or base price that is less than the then current fair market value of a share of Common Stock in exchange for other awards, cash or other property; or (iv) otherwise effect a transaction that would be considered a “repricing” for the purposes of the stockholder approval rules of the applicable securities exchange or inter-dealer quotation system on which the Common Stock is listed or quoted without stockholder approval.

Transferability of Awards. Except as described below, awards under the 2021 Plan generally are not transferable by the recipient other than by will or the laws of descent and distribution. Any amounts payable or shares issuable pursuant to an award generally will be paid only to the recipient or the recipient’s beneficiary or representative. The committee has discretion, however, to permit certain transfer of awards to other persons or entities.

Adjustments. As is customary in incentive plans of this nature, each share limit and the number and kind of shares available under the 2021 Plan and any outstanding awards, as well as the exercise price or base price of awards, and performance targets under certain types of performance-based awards, are subject to adjustment in the event of certain reorganizations, mergers, combinations, recapitalizations, stock splits, stock dividends, or other similar events that change the number or kind of shares outstanding, and extraordinary dividends or distributions of property to the stockholders.

Amendment and Termination. The board of directors may amend, modify or terminate the 2021 Plan without stockholder approval, except that stockholder approval must be obtained for any amendment that, in the reasonable opinion of the board or the committee, constitute a material change requiring stockholder approval under applicable laws, policies or regulations or the applicable listing or other requirements of a stock exchange on which shares of Common Stock are then listed. The 2021 Plan will terminate upon the earliest of (1) termination of the 2021 Plan by the board of directors, or (2) the tenth anniversary of the board adoption of the 2021 Plan. Awards outstanding upon expiration of the 2021 Plan shall remain in effect until they have been exercised or terminated, or have expired.

ITEM 12. SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED STOCKHOLDER MATTERS

The following table sets forth the number of shares of Common Stock beneficially owned as of March 1, 2026 by:

•each of our stockholders who is known by us to beneficially own 5% or more of our Common Stock;

•each of our named executive officers;

•each of our directors; and

•all of our directors and current executive officers as a group.

Beneficial ownership is determined based on the rules and regulations of the SEC. A person has beneficial ownership of shares if such individual has the power to vote and/or dispose of shares. This power may be sole or shared and direct or indirect. Applicable percentage ownership in the following table is based on 2,540,518 shares outstanding as of March 1, 2026. In computing the number of shares beneficially owned by a person and the percentage ownership of that person, shares of Common Stock that are subject to options or warrants held by that person and exercisable as of, or within 60 days of March 1, 2026, are counted as outstanding. These shares, however, are not counted as outstanding for the purposes of computing the percentage ownership of any other person(s). Except as may be indicated in the footnotes to this table and pursuant to applicable community property laws, each person named in the table has sole voting and dispositive power with respect to the shares of Common Stock set forth opposite that person’s name. Unless indicated below, the address of each individual listed below is c/o Intensity Therapeutics Inc., 1 Enterprise Drive, Suite 430, Shelton, CT 06484-4779.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR INDEPENDENCE

In addition to the compensation arrangements, including employment, termination of employment and change in control arrangements and indemnification arrangements, discussed, when required, in the sections titled “Management” and “Executive Compensation,” the following is a description of each transaction since January 1, 2024 and each currently proposed transaction in which:

•we have been or are to be a participant;

•the amount involved exceeded or exceeds the lesser of $120,000 or 1% of our assets; and

•any of our directors, executive officers or holders of more than 5% of our capital stock, or any immediate family member of, or person sharing the household with, any of these individuals, had or will have a direct or indirect material interest.

Indemnification Agreements

We entered into indemnification agreements with our directors and executive officers. The indemnification agreements provide for indemnification against expenses, judgments, fines and penalties actually and reasonably incurred by an indemnitee in connection with threatened, pending or completed actions, suits or other proceedings, subject to certain limitations. The indemnification agreements also provide for the advancement of expenses in connection with a proceeding prior to a final, non-appealable judgment or other adjudication, provided that the indemnitee provides an undertaking to repay to us any amounts advanced if the indemnitee is ultimately found not to been titled to indemnification by us. The

indemnification agreement set forth procedures for making and responding to a request for indemnification or advancement of expenses, as well as dispute resolution procedures that apply to any dispute between us and an indemnitee arising under the Indemnification Agreements.

Policies and Procedures for Related Party Transactions

We have adopted a policy that our executive officers, directors, nominees for election as a director, beneficial owners of more than 5% of any class of our Common Stock, any members of the immediate family of any of the foregoing persons and any firms, corporations or other entities in which any of the foregoing persons is employed or is a partner or principal or in a similar position or in which such person has a 5% or greater beneficial ownership interest, which we refer to collectively as related parties, are not permitted to enter into a transaction with us without the prior consent of our board of directors acting through the audit committee or, in certain circumstances, the chairman of the audit committee. Any request for us to enter into a transaction with a related party, in which the amount involved exceeds $100,000 and such related party would have a direct or indirect interest must first be presented to our audit committee, or in certain circumstances the chairman of our audit committee, for review, consideration and approval. In approving or rejecting any such proposal, our audit committee, or the chairman of our audit committee, is to consider the material facts of the transaction, including, but not limited to, whether the transaction is on terms no less favorable than terms generally available to an unaffiliated third party under the same or similar circumstances, the extent of the benefits to us, the availability of other sources of comparable products or services and the extent of the related party’s interest in the transaction.

Director Independence

Based on information requested from and provided by each of our directors, our board of directors has determined that Messrs. Mark Goldberg and Daniel Donovan and Ms. Emer Leahy are “independent directors” as such term is defined in the rules of the Nasdaq’s corporate governance requirements and Rule 10A-3 promulgated under the Securities Exchange Act of 1934, as amended.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of

Intensity Therapeutics, Inc.

Opinion on the Financial Statements

We have audited the accompanying balance sheets of Intensity Therapeutics, Inc. (the “Company”) as of December 31, 2025 and 2024, and the related statements of operations, changes in stockholders’ equity, and cash flows for each of the years then ended, and the related notes (collectively referred to as the “financial statements”). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Going Concern

The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the financial statements, the Company has incurred losses from operations and negative cash flows from operations that raise substantial doubt about its ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 2. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

We have served as the Company’s auditor since 2017.

NOTES TO FINANCIAL STATEMENTS

Note 1. Description of Business

Intensity Therapeutics, Inc. (“the Company”) is a biotechnology company whose treatment approach addresses both the regional and systemic nature of a patient’s cancer. The Company’s DfuseRxSM technology platform has identified a lead drug, INT230-6. The Company is based in Connecticut and was incorporated in Delaware in December 2012.

On February 19, 2026, the Company effected a 1-for-25 reverse stock split (the “Reverse Stock Split”). Every 25 shares of the Company’s issued and outstanding shares of the Company’s common stock were automatically converted into one share of the Company’s common stock. All fractional shares created by the Reverse Stock Split were paid in cash. The Reverse Stock Split has no impact on the par value per share of the Company’s common stock which remain at $.0001. All holders of options and warrants had the exercise price multiplied by 25 and the number of shares issuable upon exercise divided by 25. All current and prior period amounts related to shares, share prices and loss per share, presented in the Company’s financial statements and the accompanying notes have been restated for the Reverse Stock Split.

Note 2. Liquidity and Plan of Operation

The accompanying financial statements have been prepared in conformity with generally accepted accounting principles, which contemplate continuation of the Company as a going concern.

The Company is a research and development company and has not generated any revenue from its product candidates. The Company has experienced net losses and negative cash flows from operations each year since its inception. Through December 31, 2025, the Company has an accumulated deficit of $78.4 million. The Company’s operations have been financed primarily through the sale of equity securities and convertible notes. The Company’s net loss for the year ended December 31, 2025 was $11.6 million. The Company expects to incur significant expenses to complete development of its product candidates. The Company may never be able to obtain regulatory approval for the marketing of any of its product candidates in the United States or internationally and there can be no assurance that the Company will generate revenues or ever achieve profitability. The Company does not expect to receive significant product revenue in the near term. The Company, therefore, expects to continue to incur substantial losses for the foreseeable future.

Cash and cash equivalents totaled $11.9 million as of December 31, 2025. Until such time the Company can generate substantial product revenue, the Company expects to finance its operations through a combination of equity offerings and convertible debt financings. The Company does not have any committed external source of funds. To the extent that the Company can raise additional capital through the sale of equity or convertible debt securities, the ownership interest of the Company stockholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of the common stockholders. If the Company is unable to raise additional funds through equity or debt financings when needed, the Company may be required to delay, limit, reduce or terminate its research and product development.

Based on the cash and cash equivalents as of December 31, 2025, the Company believes that it has sufficient cash into the second quarter of 2027 for its current operations. Notwithstanding the projected cash runway, the Company's ability to continue its operations thereafter is dependent on obtaining additional capital, which is not within the Company's control. As a result, the Company believes there is substantial doubt about its ability to continue as a going concern.

Note 3. Basis of Presentation and Summary of Significant Accounting Policies

Basis of presentation

The accompanying financial statements have been prepared in accordance with generally accepted accounting principles in the United States of America (“GAAP”) and reflect the operations of the Company. The Company neither owns nor controls any subsidiary companies.
