On February 12, 2025, we closed the transactions pursuant to a securities purchase agreement with certain institutional investors (the “Investors”), in which we issued and sold, in a registered direct offering directly to the Investors (the “February 2025 Offering”): (i) 4,511,278 shares (the “Shares”) of our Class A common stock and (ii) warrants to purchase up to 4,511,278 shares of our Class A common stock (the “Warrants”). Each Share and accompanying Warrant were sold together at a combined offering price of $1.33. The aggregate gross proceeds to from the February 2025 Offering were $6.0 million before deducting the placement agent’s fees and offering expenses.
Subsequent to September 30, 2025, on October 17, 2025, we closed an underwritten public offering (the “October 2025 Offering”), in we issued and sold 14,000,000 shares of our Class A common stock at a public offering price of $1.25 per share, pursuant to an Underwriting Agreement (the “Underwriting Agreement”) with Lake Street Capital Markets, LLC, as the underwriter. On October 17, 2025, we received gross proceeds of $17.5 million from the October 2025 Offering, before deducting underwriting discounts and commissions and other offering expenses, and net proceeds of approximately $16.0 million, after deducting underwriting discounts and commissions and other offering expenses.
Under the terms of the Underwriting Agreement, the underwriter had a 30-day option to purchase up to an additional 2,100,000 shares of Class A common stock at the public offering price, less underwriting discounts and commissions (the “Underwriter Option”). On October 21, 2025, the underwriter notified us that it was exercising the Underwriter Option. On October 23, 2025, we received additional gross proceeds of $2.6 million from the exercise of the Underwriter Option, before deducting underwriting discounts and commissions and other offering expenses, and additional net proceeds of approximately $2.4 million, after deducting underwriting discounts and commissions and other offering expenses.
Our aggregate gross proceeds from the October 2025 Offering, including the gross proceeds from the exercise of the Underwriter Option, were $20.1 million, before deducting underwriting discounts and commissions and other offering expenses. Our aggregate net proceeds from the October 2025 Offering, including the net proceeds from the exercise of the Underwriter Option, were approximately $18.4 million, after deducting underwriting discounts and commissions and other offering expenses.
Our ability to access capital when needed is not assured and, if capital is not available when, and in the amounts needed, we could be required to delay, scale back or abandon some or all of our development programs, commercialization of our products, and other operations which could materially harm our operations, financial condition and operating results. We expect that our existing cash and cash equivalents, including the net proceeds from the October 2025 Offering, together with proceeds from the sales of our products and services, will enable us to conduct our planned operations for at least the next 12 months. Factors that could accelerate cash needs include: (i) delays in achieving scientific and technical milestones; (ii) unforeseen capital expenditures and fabrication costs related to manufacturing; (iii) changes we may make in our business or commercialization and hiring strategy; (iv) costs of running a public company; (v) higher inflation and increases in product transportation and labor costs; (vi) the effects of the tariffs; and (vii) other items affecting our forecasted level of expenditures and use of cash resources including potential acquisitions.
We expect to use our cash to further invest in the development of our products and services, commercial expansion, and for working capital and general corporate purposes.
Our future cash requirements will depend on many factors, including market adoption of our products; the cost and timing of establishing additional sales, marketing and distribution capabilities; the cost of our research and development activities; our ability to enter into and maintain collaborations; the cost and timing of potential future regulatory clearances or approvals for our products; and the effect of competing technological and market developments. We cannot assure you that we will be able to obtain additional funds on acceptable terms, or at all. If
