Item 8.01          Other Events.

On August 7, 2023, Collegium Pharmaceutical, Inc. (“Collegium” or the “Company”) announced the execution of an accelerated share repurchase agreement (the “ASR Agreement”) with Jefferies LLC to repurchase $50 million of the Company’s common stock. The ASR Agreement was undertaken as part of the $100 million share repurchase program authorized by its Board of Directors in January 2023.

Under terms of the ASR Agreement, the Company will pay $50 million to Jefferies LLC and will receive an initial delivery of approximately 1.7 million shares, based on the $23.49 closing stock price of Collegium’s common stock on August 4, 2023, representing approximately 80% of the total shares the Company expects to repurchase under the ASR Agreement. The final number of shares repurchased will be based on the volume-weighted average prices of Collegium’s common stock during the term of the ASR Agreement and subject to adjustments related to the terms and conditions of the ASR Agreement. The final settlement of the ASR Agreement is expected to be completed in the fourth quarter of 2023. As of June 30, 2023, Collegium had approximately 34.7 million shares outstanding.
