Tempest Adopts Limited Duration Stockholder Rights Plan

BRISBANE, Calif., Oct. 11, 2023 (GLOBE NEWSWIRE) — Tempest Therapeutics, Inc. (Nasdaq: TPST), a clinical-stage oncology company developing first-in-classⁱ therapeutics that combine both targeted and immune-mediated mechanisms, today announced that its Board of Directors (the “Board”) has adopted a limited duration stockholder rights plan, effective immediately (the “Rights Plan”).

Stephen Brady, president and chief executive officer of Tempest, stated: “Today we announced exciting new randomized data in first-line HCC from our lead program, TPST-1120. Unfortunately, Tempest, like many other biotechnology companies, continues to experience a significant and ongoing dislocation in the trading price of its common stock. We intend the Rights Plan to enable all of our stockholders to realize the long-term value of their investment. The Rights Plan should reduce the likelihood that any person or group gains control of Tempest through open market accumulation without paying all stockholders an appropriate control premium or without providing the Board sufficient time to make informed judgments and take actions that are in the best interests of all stockholders.”

The Board did not adopt the Rights Plan in response to a specific takeover threat. In addition, the Rights Plan does not prevent the Board from engaging with parties or accepting an acquisition proposal if the Board believes that it is in the best interests of Tempest and all of its stockholders. The Rights Plan is similar to other plans adopted by publicly held companies in comparable circumstances, and does not contain any dead-hand, slow-hand, no-hand or similar feature that limits the ability of a future Board to redeem the rights.

In connection with the adoption of the Rights Plan, the Board declared a dividend of one right for each outstanding share of the Company’s common stock as of the close of business on October 23, 2023, the record date. The rights will be exercisable only if a person or group (an “acquiring person”) acquires or launches a tender or exchange offer to acquire beneficial ownership (which includes certain synthetic equity interests) of 10% or more of the Company’s outstanding common stock (15% for certain passive institutional investors as described in the Rights Plan). Any stockholders with beneficial ownership of the Company’s outstanding common stock above the applicable threshold as of the time of this announcement are grandfathered at their current ownership levels but are not permitted to increase their ownership without triggering the Rights Plan. Once the rights become exercisable, each right will entitle its holder (other than the acquiring person, whose rights will become void) to purchase, for $25.00, additional shares of the Company’s common stock having a market value of twice such exercise price. In addition, the Rights Plan has customary flip-over and exchange features.

The Rights Plan will expire on October 10, 2024 or, if Tempest’s stockholders approve the Rights Plan, on October 10, 2026, unless the rights are earlier redeemed by the Company. Additional information regarding the Rights Plan will be contained in a Form 8-K to be filed by the Company with the U.S. Securities and Exchange Commission.
