Reverse Stock Split - On May 30, 2024, we effected a 1-for-15 reverse stock split of our common stock, and reduced the authorized common shares from 100,000,000 to 50,000,000. The par value was not adjusted as a result of the reverse stock split. All issued and outstanding common stock, warrants, stock options, restricted stock units and per share amounts contained in the accompanying consolidated financial statements and notes have been retroactively adjusted to give effect to the reverse stock split for all periods presented.

 

February 2024 Financing - On February 9, 2024, we entered into a Securities Purchase and Registration Rights Agreement relating to a private placement with certain qualified institutional buyers and institutional accredited investors, which closed on February 13, 2024. Pursuant to the agreement, we sold 134,199 shares of our common stock, and warrants to purchase 67,104 shares of our common stock at an exercise price equal to $6.60 per warrant share, subject to certain adjustments, as provided under the terms of the warrant, which are exercisable at any time before February 13, 2026. The gross proceeds of the Offering were $875,000, with associated issuance costs of $43,000.

 

At-the-Market (ATM) Offerings – On April 12, 2022, we entered into a sales agreement (Cantor Sales Agreement) with Cantor Fitzgerald & Co. (Cantor) as the sales agent, pursuant to which we may offer and sell, from time to time, through Cantor, shares of common stock having an aggregate offering price of up to $10.5 million (ATM Offering). Under the terms of the Cantor Sales Agreement, Cantor was paid a commission of 3% of the aggregate proceeds from the sale of shares and reimbursed certain legal fees. The prospectus supplement expired in conjunction with the expiration of the corresponding registration statement on October 20, 2023. On June 20, 2023, we agreed with Cantor to indefinitely suspend sales under the ATM Offering, and on November 14, 2023, we agreed to terminate the Cantor Sales Agreement.

 

On December 6, 2023, we entered into an At The Market Offering Agreement (the Sales Agreement) with H.C. Wainwright & Co., LLC (HCW). Under the Sales Agreement, we may offer and sell our common stock, from time to time having an aggregate offering price of up to $2.75 million during the term of the Sales Agreement through or to HCW as sales agent or principal, of which $264,000 was available as of June 30, 2024. We have filed a prospectus supplement relating to the offer and sale of the shares pursuant to the Sales Agreement. The offering and sale of the shares will be made pursuant to the Company’s previously filed and effective Registration Statement on Form S-3 (File No. 333-275099), which was initially filed with the Securities and Exchange Commission (the SEC) on October 19, 2023 and declared effective on December 5, 2023. We have agreed to pay HCW a commission equal to 3% of the gross proceeds from the sales of shares and have agreed to provide HCW with customary indemnification and contribution rights.
