Equity [Abstract] |
Equity | (13) Equity At-the-Market Offering Agreement On March 21, 2024, the Company entered into an At-the-Market Offering Agreement with an aggregate offering price of up to $7.0 million (the “2023 ATM Facility”). On August 30, 2024 the aggregate offering price under the 2023 ATM Facility was increased to approximately $16.0 million. It was then reduced to approximately $2.9 million in September 2024 and increased again to approximately $60.0 million in December 2024. The Company received proceeds of approximately $18.0 million under this facility prior to termination of the facility effective August 8, 2025. On August 8, 2025, the Company entered into an At Market Issuance Sales Agreement with Ladenburg Thalmann &Co. Inc., under which the Company may, from time to time, offer and sell shares of its common stock having an aggregate gross sales price of up to $40.0 million. The shares will be offered pursuant to the Company’s shelf registration statement on Form S-3, including the related prospectus supplement filed with the SEC on August 8, 2025. Sales, if any, will be made in transactions deemed to be “at the market offerings” as defined in Rule 415(a)(4) under the Securities Act, directly on or through the NYSE American or in negotiated transactions as otherwise permitted under the Sales Agreement. The Company is not obligated to sell any shares under the Ladenburg sales agreement and may suspend or terminate the offering at any time. A total of 4,929,253 shares were sold under the Ladenburg sales agreement during the three and six months ended October 31, 2025 totaling proceeds of $2.7 million. Convertible Debt Issuance In May 2025 we issued $10.0 million in aggregate principal amount (0% interest rate) of convertible notes with a 24-month maturity to new institutional investors with net proceeds of $9.7 million. The notes are convertible into shares of our common stock under specific terms outlined in the Securities Purchase Agreement and Indenture. This financing was aimed at providing us with additional liquidity, supporting the commercialization of our systems, and advancing our autonomous maritime solutions. The convertible debt structure offers the potential for conversion into equity, which may result in dilution to existing shareholders upon conversion. On October 7, 2025, we issued and sold to the investors $6.5 million of additional notes. We can draw an additional $8.5 million of notes under the purchase agreement. Principal and interest conversion during the three and six months ended October 31, 2025 was approximately $2.0 million and $5.2 million, respectively. The convertible debt has a conversion feature was determined to be an embedded derivative that requires bifurcation and separate accounting from the host instrument. At inception, the fair value of the derivative liability was approximately $699,000 for the May issuance and $489,000 for the October issuance. The sale of additional equity under new facilities could result in dilution to our shareholders. If additional funds are raised through the issuance of debt securities or preferred stock, these securities could have rights senior to those associated with our common stock and could contain covenants that would restrict our operations. The Company cannot be certain that additional equity and/or debt financing will be available to the Company as needed on acceptable terms, or at all. If we are unable to obtain required financing when needed, we may be required to reduce the scope of our operations, including our planned incremental product development and marketing efforts, which could materially and adversely affect our financial condition and operating results. If we are unable to secure additional financing, we may be forced to cease our operations.
