The Company has authorized 10,000,000 shares of preferred stock, $0.0001 par value per share, of which 0 shares were issued and outstanding as of December 31, 2023 and December 31, 2022, respectively.

On October 12, 2022, the Board of Directors (the “Board”), declared a dividend of 0.008 of a share of Series A Preferred Stock (“Series A Preferred Stock”), for each outstanding share of Common Stock to stockholders of record at 5:00pm Eastern Time on October 22, 2022. The Certificate of Designation of Series A Preferred Stock was filed with the Delaware Secretary of State and became effective on October 12, 2022. The dividend was based on the number of outstanding shares of common stock prior to the Reverse Stock Split. This resulted in 1,002,247.048 shares of preferred stock being issued. The outstanding shares of Series A Preferred Stock were entitled to vote together with the outstanding shares of common stock as a single class exclusively with respect to any proposal to adopt an amendment to the Company’s Amended and Restated Certificate of Incorporation, as amended (the “Certificate of Incorporation”), to reclassify the outstanding shares of Common Stock into a smaller number of shares of Common Stock at a ratio specified in or determined in accordance with the terms of such amendment, as well as any proposal to adjourn any meeting of stockholders called for the purpose of voting on the Reverse Stock Split Proposal (the “Adjournment Proposal”).

The Company held a special meeting of stockholders on December 20, 2022 (the “Special Meeting”) for the purpose of voting on the Reverse Stock Split and the Adjournment Proposal. All shares of Series A Preferred Stock that were not present in person or by proxy at the Special Meeting, which totaled 500,894.04 shares, were automatically redeemed by the Company immediately prior to the opening of the polls at Special Meeting (the “Initial Redemption”). All shares that were not redeemed pursuant to the Initial Redemption would be redeemed if ordered by the Board or automatically upon the effectiveness of the amendment to the Certificate of Incorporation implementing the Reverse Stock Split (the "Subsequent Redemption" and together with the Initial Redemption, the "Redemption"). Each share of Series A Preferred Stock is entitled to receive $0.001 in cash for each 10 whole shares of Series A Preferred Stock immediately prior to the Redemption.

At the Special Meeting, both the Reverse Stock Split and Adjournment Proposal were approved.

Upon issuance of the Series A Preferred Stock, the Company was not solely in control of the Redemption of the shares of Series A Preferred Stock since the holders had the option of deciding whether to attend or return a proxy card for the Special Meeting, which determined whether a given holder’s shares of Series A Preferred Stock were redeemed in the Initial Redemption. Since the Redemption of the Series A Preferred Stock was not solely in the control of the Company, the shares of Series A Preferred Stock are classified within mezzanine equity. The shares of Series A Preferred Stock were initially recorded at redemption value, which approximated fair value.

After the Special Meeting upon approval of the Reverse Stock Split, the remaining 501,353.008 shares outstanding of Series A Preferred Stock were considered mandatorily redeemable and reclassified to a current liability. As of December 31, 2022, the fair value of the Series A Preferred Stock were included in accrued expenses. The Series A Preferred Stock were redeemed on February 14, 2023, upon the effectiveness of the amendment to the Certificate of Incorporation implementing the Reverse Stock Split pursuant to the terms of the Certificate of Designation of the Series A Preferred Stock.
