The Company has incurred significant operating losses and has an accumulated deficit as a result of its efforts to develop product candidates and provide general and administrative support for operations. As of March 31, 2026, the Company had a cash balance of approximately $9.2 million and an accumulated deficit of approximately $251.1 million. For the three months ended March 31, 2026, the Company incurred a net loss of $5.5 million, which includes a non-cash charge of $2.0 million for the impairment of goodwill, and it used cash of $2.3 million in operating activities.

On February 10, 2026, the Company received approximately $9.5 million in net proceeds from a public offering (the “Public Offering”) of (i) 0.8 million shares of the Company’s common stock or pre-funded warrants and (ii) accompanying warrants to purchase 0.8 million shares of the Company’s common stock (the “Milestone Warrants”). See Note 8 for more information regarding the Public Offering.

On March 13, 2026, the Company filed a Registration Statement on Form S-3 with the SEC to offer and sell up to $50.0 million of its common stock from time to time in one or more offerings (the “Universal Shelf”), which became effective on March 30, 2026. The Universal Shelf includes a prospectus supplement providing for sales of up to $9.2 million of common stock pursuant to an At-the-Market (“ATM”) program.

The Company is subject to General Instruction I.B.6 of Form S-3 (the “baby shelf” rules), which limits the aggregate market value of securities the Company may sell under the Universal Shelf to no more than one-third of its public float in any 12-month period while its public float remains below $75.0 million. As of the filing of the Universal Shelf, one-third of the Company’s public float was approximately $9.2 million, representing the maximum amount to be sold under the ATM. As of March 31, 2026, the Company has not sold any securities under the ATM.

In connection with preparing the financial statement as of and for the three months ended March 31, 2026, the Company evaluated whether there are conditions and events, considered in the aggregate, that are known and reasonably knowable that would raise substantial doubt about its ability to continue as a going concern within one year after the date that the financial statements are issued.

As of April 30, 2026, the Company had approximately $8.3 million in cash, which is less than that needed to effect its current operating plan and forecasted cash requirements for the next twelve months. However, management expects that its ability to access capital under its ATM will cover shortfalls in its cash resources over the next twelve months from the issuance date of these financial statements.

If the Company’s cash is not sufficient to meet future cash requirements, the Company may be required to reduce planned capital expenses, reduce operational cash uses or raise capital on terms that are not as favorable to the Company as they otherwise might be. Any actions the Company may undertake to reduce planned capital purchases or reduce expenses may be insufficient to cover shortfalls in available funds. If the Company requires additional capital, it may be unable to secure additional financing on terms that are acceptable to the Company, or at all.
