**Item 8.01. Other Events**

On March 23, 2026, Intensity Therapeutics, Inc. (the "Company") filed a prospectus supplement to increase the capacity of its existing "at-the-market" offering program (the "ATM") to $60.0 million. While this filing increases the available capacity under the ATM, the Company is under no obligation to issue any shares (the "Shares") pursuant to the program. The expanded facility is intended to enhance the Company's financial flexibility, providing an efficient mechanism to access capital if, and when, deemed appropriate. Any utilization of the ATM will be at the discretion of the Company, taking into account prevailing market conditions and strategic priorities.

As previously disclosed, the ATM is conducted pursuant to the at the market offering agreement (the "Offering Agreement"), dated July 3, 2024, by and among the Company and H.C. Wainwright & Co. LLC (the "Sales Agent). Accordingly, pursuant to the prospectus supplement, the amount of shares of the Company's common stock, par value $0.0001 per share, that the Company may issue under the Offering Agreement has been increased to an aggregate of $60.0 million of Shares. There can be no assurance that the Sales Agent will be able to complete future placements pursuant to the Offering Agreement, even if instructed to do so. The number of Shares that the Company may ultimately sell under the Offering Agreement, if it chooses to do so, will fluctuate based on a number of factors, including the market price of its common stock during the sales period, the limits it may set in any instruction to sell Shares, and the demand for its common stock during an applicable sales period.

Attached hereto as Exhibit 5.1 to this Current Report is the opinion of Mintz, Levin, Cohn, Ferris, Glovsky and Popeo, P.C., relating to the legality of the issuance and sale of the Shares.

Ladies and Gentlemen:

We have acted as counsel to Intensity Therapeutics, Inc., a Delaware corporation (the "***Company***"), with respect to certain matters in connection with the offering by the Company of up to $60 million of shares of the Company's common stock, par value $0.0001 per share (the "***Shares***"), pursuant to the Registration Statement on Form S-3 (File No. 333-280681) (the "***Registration Statement***"), filed with the Securities and Exchange Commission (the "***Commission***") under the Securities Act of 1933, as amended (the "***Act***"), the related prospectus dated July 11, 2024 included within the Registration Statement (the "***Base Prospectus***"), and the prospectus supplement dated July 11, 2024, prospectus supplement dated November 20, 2024, prospectus supplement dated June 11, 2025, prospectus supplement dated December 4, 2025, and prospectus supplement dated March 23, 2026 filed with the Commission pursuant to Rule 424(b) promulgated under the Act (together with the Base Prospectus, the "***Prospectus***"). The Shares are to be sold by the Company in accordance with that certain at the market offering agreement, dated as of July 3, 2024, by and between the Company and H.C. Wainwright & Co., LLC (the "***Offering Agreement***"), as described in the Prospectus.

In connection with this opinion, we have examined the Company's Sixth Amended and Restated Certificate of Incorporation and Second Amended and Restated Bylaws, both as currently in effect, such other records of the corporate proceedings of the Company and certificates of the Company's officers as we have deemed relevant, as well as the Registration Statement and the exhibits thereto and the Prospectus.

In our examination, we have assumed the genuineness of all signatures, the legal capacity of natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as certified, photostatic or facsimile copies and the authenticity of the originals of such copies.

Based upon the foregoing, and subject to the limitations set forth below, we are of the opinion that the Shares, when issued by the Company out of the Company's duly authorized common stock and issued and delivered by the Company against payment therefor as contemplated by and in accordance with the terms of the Offering Agreement, on terms approved by the Board of Directors of the Company, or a duly authorized committee thereof, will be duly and validly issued, fully paid and nonassessable.

Our opinion is limited to the General Corporation Law of the State of Delaware, and we express no opinion with respect to the laws of any other jurisdiction. No opinion is expressed herein with respect to the qualification of the Shares under the securities or blue sky laws of any state or any foreign jurisdiction.

We have relied as to certain matters on information obtained from public officials, officers of the Company, and other sources believed by us to be responsible.

Please note that we are opining only as to the matters expressly set forth herein, and no opinion should be inferred as to any other matters. This opinion is based upon currently existing statutes, rules, regulations and judicial decisions, and we disclaim any obligation to advise you of any change in any of these sources of law or subsequent legal or factual developments which might affect any matters or opinions set forth herein.

We hereby consent to the filing of this opinion as an exhibit to a Current Report on Form 8-K in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Act and to the use of this firm's name therein and in the
