On September 27, 2022, the Company filed a Certificate of Amendment to the Certificate of Incorporation (the “Amendment”) with the Delaware Secretary of State to effect a reverse stock split of all outstanding shares of the Company’s common stock at a ratio of one-for-12. At the Company’s 2022 Annual Meeting of Stockholders, holders of a majority of the outstanding voting power approved an amendment to the Certificate of Incorporation of the Company to effect a reverse stock split of all outstanding shares of our common stock at a ratio to be determined by the Board of Directors within a range of one-for-four through one-for-12. Following such approval, The Board of Directors determined to effect the reverse stock split at the ratio of one-for-12. The Amendment became effective October 11, 2022 and the effect of the reverse stock split was reflected on the Nasdaq Stock Market.

On October 18, 2022 the Company approved the issuance of an additional 20,841 shares of common stock to facilitate the rounding up of fractional shares resulting from the above reverse stock split.

All share and per share amounts have been retroactively restated to reflect the one-for-12 stock split as if it occurred at the beginning of the earliest period presented.
