As previously reported, on December 14, 2023, Better Therapeutics, Inc. (the “Company”) received notice from the Listing Qualifications Staff (the “Staff”) of The Nasdaq Stock Market LLC (“Nasdaq”) indicating that, based upon the Company’s non-compliance with the minimum bid price and market value of listed securities requirements for continued listing on The Nasdaq Capital Market, the Company’s securities were subject to delisting unless the Company timely requested a hearing before the Nasdaq Hearings Panel (the “Panel”). On December 21, 2023, the Company requested a hearing before the Panel, which temporarily stayed the suspension of trading and delisting of the Company’s common stock. The hearing occurred on March 14, 2024, and the Company voluntarily requested a delisting of its securities at the hearing.

As a result, Nasdaq issued a notice to the Company that its shares will be suspended from trading at the open of business on March 18, 2024, and Nasdaq will file a Form 25 Notification of Delisting with the Securities and Exchange Commission after applicable appeal periods have lapsed. The Company further intends to file a Form 15 with the Securities and Exchange Commission to suspend its reporting obligations under the Securities Exchange Act of 1934, as amended.
