Reverse Stock Split

On February 29, 2024, the Board approved and authorized the Company to implement a reverse stock split based on a final ratio of 1-for 23 of the Company’s Common Stock. Effective March 8, 2024, every 23 shares of Common Stock issued and outstanding, including shares of Common Stock held by the Company as treasury shares, were automatically combined into one share of Common Stock. The Company’s stockholders of record received a cash payment (without interest) in lieu of any fractional shares they would have otherwise been entitled to receive in the Reverse Stock Split. Under the terms of the applicable warrant agreement, the number of shares of Common Stock issuable on exercise of each warrant were proportionately decreased. Specifically, following effectiveness of the Reverse Stock Split, every 23 shares of Common Stock that may be purchased pursuant to the exercise of public warrants would represent one share of Common Stock that may be purchased pursuant to such warrants. Accordingly, every 23 warrants will be exercisable for one share of Common Stock at an exercise price of $264.50 per share of Common Stock. As of the Reverse Split Effective Time, the number of shares of Common Stock available for issuance under the Company’s equity incentive plans and issuable pursuant to equity awards immediately prior to the Reverse Stock Split were proportionately adjusted by the Reverse Stock Split. The exercise prices of the Company’s outstanding options and equity awards were adjusted in accordance with their respective terms.
