(the “Company”) held on May 21, 2026 (the\n“Annual Meeting”), the Company’s stockholders approved a proposal authorizing the board of directors of the Company\n(the “Board”), in its sole discretion, to effect one or more reverse stock splits of the outstanding shares of the Company’s\ncommon stock, par value, $0.00001 per share (the “Common Stock”), at a cumulative reverse split ratio in the range of one-for-two\n(1:2) to one-for-one hundred and fifty (1:150), as determined by the Board, whereby every two to one hundred and fifty shares of the\nissued and outstanding Common Stock will be combined into one share of issued and outstanding Common Stock. The voting results of the\nAnnual Meeting were reported on a Form 8-K filed with the Securities and Exchange Commission on May 27, 2026.\n\n \n\nPursuant\nto such authority granted by the Company’s stockholders at the Annual Meeting, on June 1, 2026, the Board approved a one-for-ten\n(1:10) reverse stock split (the “Reverse Stock Split”) of the Common Stock and on June 10, 2026, the Company filed a certificate\nof amendment to amend the certificate of incorporation of the Company (the “Certificate of Amendment”) with the\nSecretary of State of the State of Delaware, with an effective date of June 11, 2026 (the “Effective Date”). The Reverse\nStock Split became effective at the start of trading on June 11, 2026 (the “Effective Time”). Following the Reverse Stock\nSplit, every ten (10) shares of the Company’s issued and outstanding Common Stock immediately prior to the Effective Time were\nautomatically reclassified into one (1) share of Common Stock, without any change in the par value per share. The Reverse Stock Split\nreduced the number of shares of Common Stock issuable upon the exercise or vesting of the Company’s outstanding warrants, restricted\nstock units and convertible preferred stock in proportion to the ratio of the Reverse Stock Split and caused a proportionate increase\nin the exercise or conversion prices of such convertible securities, as applicable. The Reverse Stock Split did not change the total\nnumber of authorized shares of Common Stock or preferred stock.\n\n \n\nNo\nfractional shares were issued as a result of the Reverse Stock Split. Stockholders who otherwise would be entitled to receive a fractional\nshare in connection with the Reverse Stock Split received one full share of the post-Reverse Stock Split Common Stock in lieu of such\nfractional share.\n\n \n\nVStock\nTransfer LLC is acting as exchange agent for the Reverse Stock Split and will notify stockholders of record regarding the Reverse Stock\nSplit. Stockholders who hold their shares in book-entry form or in “street name” (through\na broker, bank or other holder of record) are not required to take any action.\n\n \n\nCommencing\non June 11, 2026, trading of the Company’s Common Stock continued on The Nasdaq Capital Market on a Reverse Stock Split-adjusted\nbasis. The new CUSIP number for the Company’s Common Stock following the Reverse Stock Split is 825693500.\n\n \n\nThe\nforegoing description of the Certificate of Amendment does not purport to be complete and is qualified in its entirety by reference to\nthe full text of the Certificate of Amendment, which is filed as Exhibit 3.1 to this report and incorporated by reference herein."}
