FINANCINGS | 4. FINANCINGS October 2025 Private Placement On October 9, 2025, the Company entered into a securities purchase agreement with two institutional investors pursuant to which the Company sold in a private placement (i) an aggregate of 43,750 shares of common stock and prefunded warrants to purchase up to 518,750 shares of common stock (the “October 2025 Prefunded Warrants”), and (ii) Series F warrants (the “Series F Warrants”) to purchase up to 1,125,000 shares of common stock. The combined price of the securities sold in the private placement was $8.00 per share of common stock (or prefunded warrant in lieu thereof, in which case such price was reduced by $0.0004) and accompanying Series F Warrants to acquire two shares of common stock. The October 2025 Prefunded Warrants are exercisable for shares of common stock at an exercise price of $0.0004 per share, are immediately exercisable and expire once exercised in full. The Series F Warrants are exercisable for shares of common stock at an exercise price of $7.00 per share, are immediately exercisable and expire five and one-half years from the date of issuance. The transaction closed on October 10, 2025. The gross proceeds to the Company from the sale of the securities sold in the private placement were approximately $4.5 million. The Company incurred total offering costs of $787,755, including a 8% financial advisory fee to Rodman and Renshaw LLC (“Rodman”), the placement agent, of approximately $360,000. Under the terms of the Company’s engagement letter with Rodman, the Company issue Rodman’s designees warrants to purchase up to 45,000 of common stock at an exercise price of $10.00 per share, which expire 5.5 years from the date of issuance (the “October 2025 Placement Agent Warrants”). In connection with this private placement, on November 26, 2025, the Company filed a prospectus under rule 424(b)(3) to register 1,732,500 shares of common stock for resale in public markets. Holders of the warrants will not have the right to exercise any portion of such warrants if such holder, together with its affiliates, would beneficially own in excess of 4.99% or 9.99% (at the initial election of the holder) of the number of shares of the Company’s common stock outstanding immediately after giving effect to such exercise, provided that a holder may increase or decrease such beneficial ownership limitation up to, and no higher than, 9.99%, by giving 61 calendar days’ notice to the Company. April 2025 Private Placement On April 7, 2025, the Company entered into inducement letter agreements with certain existing holders of the Company’s Class C warrants (the “Class C Warrants”), pursuant to which such holders agreed to purchase an aggregate of 271,277 shares of the Company’s common stock (or, to the extent the applicable holder would have exceeded a specified beneficial ownership limitation, prefunding the future exercise of such warrants, other than a remaining $0.0004 per share exercise price). The Class C Warrants were originally issued on June 28, 2024 for an exercise price of $392.00 per share and were subsequently reduced to $65.20 per share pursuant to stockholder approval on August 21, 2024. Pursuant to the inducement letter agreements, the applicable holders agreed to exercise their Series C Warrants at a reduced exercise price of $13.68 per share, and to purchase an equivalent number of new Class E warrants (the “Class E Warrants”) for an additional $0.50 per share. The Class E Warrants have an exercise price of $13.68 per share and expire on April 8, 2030. The transaction closed on April 8, 2025. The exercise of the Class C Warrants resulted in the Company issuing 170,551 shares of common stock at closing pursuant to the inducement letters, and the exercise price of 100,726 of the Class C Warrants being amended to 0.0004 per share. As of December 31, 2025, all such reduced exercise price Class C Warrants had been exercised. The gross proceeds to the Company from the exercise of the Class C Warrants and the sale of the new Class E Warrants were $3,846,707. The Company incurred total cash offering costs of $464,670, including a 10% financial advisory fee to Aegis Capital Corp. of $384,670. The modification of the terms or conditions of the Class C Warrants in this transaction is treated as an exchange of the original instrument for a new instrument. Using the Black Scholes option pricing model, the fair value of the Series C Warrants immediately prior to the inducement transaction was $479,299 and immediately after the inducement transaction was $1,590,930. In addition, Series E Warrants with a fair value of $1,730,652 were provided as part of the inducement transaction for a purchase price of $135,638. The Company recorded additional equity issuance costs of $2,706,645 related to the modification of the Series C Warrants and issuance of Series E Warrants related to the inducement transaction. As this equity issuance cost was a non-cash transaction, the Company recorded an increase to additional paid-in capital to offset the expense. June 2024 Public Offering On June 28, 2024, the Company sold in a public offering ( the “June 2024 Offering”), (i) 2,885 common units (the “Common Units”), each consisting of one share of common stock, two Class C Warrants and one Class D Warrant and (ii) 23,953 prefunded units (the “Prefunded Units”), each consisting of one prefunded warrant to purchase one share of common stock (each, a “June 2024 Prefunded Warrant”), two Class C Warrants and one Class D Warrant. The Common Units were sold at a price of $326.00 per unit and the Prefunded Warrants were sold at a price of $325.98 per unit. Aegis Capital Corp. (“Aegis”) partially exercised its over-allotment option in respect to 3,393 Class C Warrants and 1,696 Class D Warrants (the “Over-Allotment Warrants). As of December 31, 2024, all Prefunded Warrants had been exercised in full. Pursuant to an engagement letter dated June 6, 2024, by and between the Company and Aegis, the Company paid Aegis a total cash fee of $743,750 equal to 8.5% of the gross proceeds received in the June 2024 Offering.

May 2024 Bridge Note Financing On May 31, 2024, the Company entered into a Note Purchase Agreement with an accredited investor (the “NPA”), and a Securities Purchase Agreement with three accredited investors (the “SPA”). This transaction closed on June 3, 2024. Debt issuance costs related to the NPA and SPA totaled $212,654. Under the terms of the NPA, the first investor provided the Company with a $1,000,000 cash subscription in exchange for the issuance of a senior secured note (the “Bridge Note”). As of December 31, 2024, a total of $1,176,470 was repaid to the NPA investor in full satisfaction of the Bridge Note.

Under the terms of the SPA, the three additional investors agreed to collectively provide the Company with a separate $1,000,000 cash subscription in exchange for the issuance of senior secured notes (the “SPA Notes”), and the collective issuance of 362 shares of the Company’s common stock. The fair value of the common stock issued in connection with the SPA was $307,563. As of December 31, 2024, a total of $1,111,110 has been repaid to the SPA investors, in full satisfaction of the SPA Notes. The difference between the SPA Notes and the subscription amounts, initially recorded as a discount on the SPA Notes, was the result of the discount factor included in the SPA of 11.11%. The interest expense recorded on the NPA and SPAs was $807,797 for the year ended December 31, 2024, including debt issuance costs related to the NPA and SPA totaling $212,654.
