During the three months ended March 31, 2026, the Company sold approximately 1.3 million shares of common stock pursuant to 2025 ATM at an average price per share of approximately $2.47 resulting in approximately $3.1 million in net proceeds to the Company after deducting commissions and other offering expenses.

In connection with the Offering, the Company entered into a placement agent agreement with Craig-Hallum, pursuant to which Craig-Hallum served as the exclusive placement agent for the issuance and sale of securities of the Company pursuant to the Purchase Agreement. As compensation for such placement agent services, the Company paid Craig-Hallum an aggregate cash fee equal to 5.0% of the gross proceeds received by the Company from the Offering and agreed to reimburse up to $75,000 of legal and other expenses actually incurred. Net proceeds to the Company after deducting the placement agent fee and expenses were approximately $23.6 million.

Based on the funds it has available as of the date of the filing of this report, the Company believes that it has sufficient capital to fund its current business plans and obligations over, at least, 24 months from the date that these financial statements have been issued. The Company’s future capital requirements and the adequacy of its available funds will depend on many factors, including the Company’s ability to successfully commercialize its technology, competing technological and market developments, and the need to enter into collaborations with other companies or acquire technologies to enhance or complement its current offerings.
