Aileron Therapeutics Announces a 1-for-20 Reverse Stock Split

BOSTON, Nov. 10, 2022 (GLOBE NEWSWIRE) — Aileron Therapeutics (Nasdaq: ALRN), a chemoprotection oncology company that aspires to make chemotherapy safer and thereby more effective to save more patients’ lives, today announced that it will effect a 1-for-20 reverse stock split of its common stock. The reverse stock split will become effective at 5:00 p.m. ET today. Aileron’s common stock will continue to be traded on the Nasdaq Capital Market under the symbol “ALRN” and will begin trading on a split-adjusted basis when the market opens on November 11, 2022.

The reverse stock split, which was approved by Aileron’s stockholders on June 15, 2022, is intended to bring the company into compliance with Nasdaq’s minimum bid price requirement. The new CUSIP number for the company’s common stock following the reverse stock split will be 00887A 204.

At the effective time of the reverse stock split, every 20 shares of Aileron’s issued and outstanding common stock will be converted automatically into 1 issued and outstanding share of common stock without any change in the par value per share. This will reduce the company’s number of shares of common stock outstanding from approximately 90.8 million shares to approximately 4.5 million shares.

No fractional shares of common stock will be issued as a result of the reverse stock split. Stockholders who would otherwise be entitled to receive a fractional share will receive a cash payment in lieu thereof. The reverse stock split will affect all stockholders uniformly and will not alter any stockholder’s percentage interest in Aileron’s equity, except to the extent that the reverse stock split would result in a stockholder owning a fractional share. Proportional adjustments will be made to the number of shares of Aileron’s common stock issuable upon exercise of Aileron’s stock options and warrants, as well as the applicable exercise price.

About Aileron Therapeutics
Aileron is a clinical stage chemoprotection oncology company that aspires to make chemotherapy safer and thereby more effective to save more patients’ lives. ALRN-6924, our first-in-class MDM2/MDMX dual inhibitor, is designed to activate p53, which in turn upregulates p21, a known inhibitor of the cell replication cycle. ALRN-6924 is the only reported chemoprotective agent in clinical development to employ a biomarker strategy, in which we exclusively focus on treating patients with p53-mutated cancers. Our targeted strategy is designed to selectively protect multiple healthy cell types throughout the body from chemotherapy without protecting cancer cells. As a result, healthy cells are spared from chemotherapeutic destruction while chemotherapy continues to kill cancer cells. By reducing or eliminating multiple chemotherapy-induced side effects, ALRN-6924 may improve patients’ quality of life and help them better tolerate chemotherapy. Enhanced tolerability may result in fewer dose reductions or delays of chemotherapy and the potential for improved efficacy. Our vision is to bring chemoprotection to all patients with p53-mutated cancers, which represent approximately 50% of cancer patients, regardless of type of cancer or chemotherapy.
