Reverse Stock Split

We filed with the Secretary of State of the State of Delaware a certificate of amendment to our Amended and Restated Certificate of Incorporation, to effect a 1-for-10 reverse stock split, effective June 27, 2024. As a result of the reverse stock split, every ten issued and outstanding shares of our common stock were automatically combined into one issued and outstanding share of common stock. Accordingly, an amount equal to the par value of the decreased shares

resulting from the reverse stock split was reclassified from common stock to additional paid-in capital on the condensed balance sheet and statement of changes in stockholders’ deficit. No fractional shares were issued in connection with the reverse stock split. Stockholders who otherwise would be entitled to receive fractional shares of common stock were entitled to receive the cash value equal to the fraction to which the stockholder would otherwise be entitled, multiplied by the closing price of the common stock as reported by Nasdaq on the last trading day prior to the effective date of the split. As a result of the reverse stock split, proportionate adjustments were made to the number of shares underlying (and as applicable, the exercise or conversion prices of) our outstanding equity awards and to the number of shares of common stock issuable under our equity incentive plans. The reverse stock split did not change the par value of our common stock, which remains $0.001, or the authorized number of shares of our common stock. All share amounts and per share amounts disclosed in this Quarterly Report on Form 10-Q have been adjusted to reflect the reverse stock split on a retroactive basis for all periods presented.

Use of Estimates

The preparation of financial statements in conformity with US GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. We base our estimates on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. Actual results could differ from these estimates.
