On January 9, 2024, pursuant to prior stockholder authorization, our Board effected a reverse split of the outstanding shares of our common stock at a ratio of one share for every twenty shares then outstanding (the “Reverse Split”). Pursuant to their respective terms, the number of shares underlying our outstanding options and warrants was reduced and their respective exercise prices increased by the Reverse Split ratio. The number of shares of common stock authorized and the par value of $0.001 per share did not change as a result of the Reverse Split. All share and per share amounts contained in this Annual Report on Form 10-K give retroactive effect to the Reverse Split.

In January 2024, Fedson paid off the $1.0 million Escrow Note. We received the funds from the escrow account in February 2024.

In March 2024, the Hau Promissory Note, along with accrued interest, was converted into 54,132 shares of our common stock.
