On  August 8, 2025, the Company effected a 1-for-10 reverse stock split of its issued and outstanding common stock. As a result of the reverse split, each 10 shares of issued and outstanding common stock were automatically converted into one share of common stock. The reverse stock split did not change the total number of shares authorized or par value per share. The reverse stock split was approved by the Company’s shareholders on July 25, 2025.

All share and per share amounts presented in these consolidated financial statements and accompanying notes and elsewhere in this Annual Report on Form 10-K, including but not limited to shares issued and outstanding, loss per share, and stock options and stock appreciation rights, as well as the dollar amounts of common stock and paid-in-capital, have been retroactively adjusted for all periods presented. No fractional shares were issued in connection with the reverse stock split. Shareholders who would have otherwise been entitled to receive fractional shares as a result of the reverse stock split received a cash payment in lieu thereof, based on the closing price of the Company’s common stock on  August 7, 2025.

Lincoln Park Capital Fund LLC Purchase Agreement

On May 2, 2023, the Company entered into a purchase agreement (as amended, the “Lincoln Park Purchase Agreement”) with Lincoln Park Capital Fund, LLC (“Lincoln Park”), which provides that, upon the terms and subject to the conditions and limitations set forth therein, the Company may sell to Lincoln Park up to $100.0 million of shares (the “Purchase Shares”) of the Company’s common stock over the 36 month term of the Lincoln Park Purchase Agreement. The Lincoln Park Purchase Agreement may be terminated by the Company at any time, at its sole discretion, without any cost or penalty, by giving one business day notice to Lincoln Park. Lincoln Park has covenanted not to in any manner whatsoever enter into or effect, directly or indirectly, any short selling or hedging of the Company’s common stock. On December 13, 2023, the Company entered into an amendment (the “Lincoln Park Amendment”) with Lincoln Park to reduce the amount of shares of common stock subject to the registration from $100.0 million to $50.0 million until the Company has sold at least $50.0 million of shares of common stock under the Lincoln Park Purchase Agreement. The issuance of shares of common stock pursuant to the Lincoln Park Purchase Agreement up to $50.0 million have been registered pursuant to the Company’s effective shelf registration statement on Form S-3 (File No. 333-270606), and a related prospectus supplement that was filed with the SEC on May 3, 2023, as further supplemented on December 13, 2023 to reflect the Lincoln Park Amendment.

Under the Lincoln Park Purchase Agreement, the Company has the right, but not the obligation, on any business day selected by the Company (the “Purchase Date”), provided that on such day the closing sale price per share of the Company’s common stock is above the Floor Price, as defined in the Lincoln Park Purchase Agreement, to require Lincoln Park to purchase up to 22,500 shares of the Company’s common stock (the “Regular Purchase Amount”) at the Purchase Price (as defined below) per purchase notice (each such purchase, a “Regular Purchase”) provided, however, that (1) the limit on the Regular Purchase Amount will be increased to 25,000 shares, if the closing sale price of the Company’s common stock on the applicable Purchase Date is not below $60.00 and to 27,500 shares, if the closing sale price of the Company’s common stock on the applicable Purchase Date is not below $80.00. Lincoln Park’s committed obligation under each Regular Purchase shall not exceed $2,500,000 or 200,000 Purchase Shares per each Regular Purchase. The purchase price for Regular Purchases (the “Purchase Price”) shall be equal to the lesser of: (i) the lowest sale price of the Company’s common stock during the Purchase Date, or (ii) the average of the three lowest closing sale prices of the Company’s common stock on the 10 consecutive business days ending on the business day immediately preceding such Purchase Date. The Company shall have the right to submit a Regular Purchase notice to Lincoln Park as often as every business day. A Regular Purchase notice is delivered to Lincoln Park after the market has closed (i.e., after 4:00 P.M. Eastern Time) so that the Purchase Price is always fixed and known at the time the Company elects to sell shares to Lincoln Park.

In addition to Regular Purchases and provided that the Company has directed a Regular Purchase in full, the Company in its sole discretion may require Lincoln Park on each Purchase Date to purchase on the following business day (“Accelerated Purchase Date”) up to the lesser of (i) three (3) times the number of shares purchased pursuant to such Regular Purchase or (ii) 30% of the trading volume on the Accelerated Purchase Date (the “Accelerated Purchase”) at a purchase price equal to the lesser of 97% of (i) the closing sale price on the Accelerated Purchase Date, or (ii) the Accelerated Purchase Date’s volume weighted average price (the “Accelerated Purchase Price”). The Company may also direct Lincoln Park, on any business day on which an Accelerated Purchase has been completed and all of the shares to be purchased thereunder have been properly delivered to Lincoln Park in accordance with the Lincoln Park Purchase Agreement, to make additional purchases upon the same terms as an Accelerated Purchase (an “Additional Accelerated Purchase”).

The purchase price of Regular Purchases, Accelerated Purchases and Additional Accelerated Purchases and the minimum closing sale price for a Regular Purchase will be adjusted for any reorganization, recapitalization, non-cash dividend, stock split or other similar transaction occurring during the business days used to compute the purchase price. The aggregate number of shares that the Company can sell to Lincoln Park under the Lincoln Park Purchase Agreement may in no case exceed 1,767,850 shares (subject to adjustment as described above) of the Company’s common stock (which is equal to approximately 19.99% of the shares of the Company’s common stock outstanding immediately prior to the execution of the Lincoln Park Purchase Agreement) (the “Exchange Cap”), unless (i) shareholder approval is obtained to issue Purchase Shares above the Exchange Cap, in which case the Exchange Cap will no longer apply, or (ii) the average price of all applicable sales of the Company’s common stock to Lincoln Park under the Lincoln Park Purchase Agreement equals or exceeds $12.60 per share (subject to adjustment as described above) (which represents the Minimum Price, as defined under Nasdaq Listing Rule 5635(d), on the Nasdaq Capital Market immediately preceding the signing of the Lincoln Park Purchase Agreement, such that the transactions contemplated by the Lincoln Park Purchase Agreement are exempt from the Exchange Cap limitation under applicable Nasdaq rules).

In consideration for entering into the Lincoln Park Purchase Agreement, concurrently with the execution of the Lincoln Park Purchase Agreement, the Company issued 80,000 shares of the Company’s common stock to Lincoln Park. The shares of common stock issued as consideration were valued at $1.0 million, based on the closing price per share of the Company’s common stock on the date the shares were issued. This amount and related expenses of $57,000, which total approximately $1.1 million, were recorded as deferred costs. We are obligated to issue $1.0 million of shares of the Company’s common stock at the time Lincoln Park’s purchases cumulatively reach an aggregate amount of $50.0 million of Purchase Shares.

The Company did not sell any shares under the Lincoln Park Purchase Agreement during fiscal 2025. We sold 180,000 shares of common stock to Lincoln Park under the Lincoln Park Purchase Agreement during fiscal 2024, resulting in proceeds to the Company of $1.7 million. As a result of these sales, we recorded approximately $0.2 million of deferred costs to additional paid-in capital. The unamortized amount of deferred costs related to the Lincoln Park Purchase Agreement is $0.9 million at each of  September 30, 2025 and 2024 and is included in other assets on the accompanying consolidated balance sheets.

At-the-Market Sale Agreement

On May 12, 2023, the Company entered into an Open Market Sale Agreement℠ (the “Jefferies Sales Agreement”) with Jefferies LLC (“Jefferies”), as sales agent, pursuant to which the Company may issue and sell, from time to time, through Jefferies, shares of the Company’s common stock, with an aggregate value of up to $75 million (not to exceed the lesser of 3,960,907 shares of common stock or the number of authorized, unissued and available shares of common stock at any time). Shares of common stock offered and sold pursuant to the Jefferies Sale Agreement have been registered pursuant to the Company’s effective shelf registration statement on Form S-3 (File No. 333-270606), and a related prospectus supplement that was filed with the SEC on May 12, 2023. On August 19, 2024, the Company delivered notice to Jefferies to terminate the Jefferies Sales Agreement, which was effective on September 3, 2024. Pursuant to the terms of the Jefferies Sales Agreement, the Company could issue and sell, from time to time through or to Jefferies, shares of its common stock as set forth in the Jefferies Sales Agreement with an aggregate value of up to $75 million. As a result of the termination of the Jefferies Sales Agreement, the Company will not issue or sell any additional shares of common stock under the Jefferies Sales Agreement.

We did not sell any shares of common stock under the Jefferies Sales Agreement during fiscal 2025. We sold 9,016 shares of common stock under the Jefferies Sales Agreement during fiscal 2024, resulting in net proceeds to the Company of $0.1 million. The Company incurred issuance costs related to the Jefferies Sales Agreement of $0.2 million, which were recorded as deferred costs. The unamortized amount of deferred costs remaining when the agreement terminated was $0.2 million and was expensed at the time of termination. It is included in selling, general and administrative expenses on the accompanying consolidated statement of operations for the year ended September 30, 2024.
