**PART III -- NARRATIVE**

State below in reasonable detail why the Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR or the transition report portion thereof could not be filed within the prescribed time period.

Esperion Therapeutics, Inc. (the "Company") has determined that it is unable to file, without unreasonable effort or expense, its Quarterly Report on Form 10-Q for the quarter ended June 30, 2025 (the "Form 10-Q") with the Securities and Exchange Commission (the "SEC") within the prescribed time period, as the Company has not yet completed its quarter-end financial close process for the quarter ended June 30, 2025. In connection with the preparation of its Form 10-Q, management identified certain errors in the earnings release for the quarter ended June 30, 2025, furnished with its Current Report on Form 8-K filed on August 5, 2025, and subsequently corrected such errors by furnishing an amended version of the earnings release with its Current Report on Form 8-K/A filed on August 11, 2025. The preliminary financial data in the amended earnings release is based on unaudited information and management estimates for the quarter ended June 30, 2025 as of the date of its issuance, and remains subject to completion of the Company's financial closing procedures. As a result, the Company requires additional time to complete its financial closing procedures and finalize its condensed financial statements for inclusion in the Form 10-Q. The Company currently expects to file the Form 10-Q with the SEC as soon as practicable, and no later than the fifth calendar day following the prescribed due date, in accordance with Rule 12b-25.

**Forward-Looking Statements** 

This Notification of Late Filing on Form 12b-25 contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Any statements about the Company's expectations, beliefs, plans, objectives, assumptions or future events or performance are not historical facts and may be forward-looking. These statements are often, but are not always, made through the use of words or phrases such as "may," "will," "could," "should," "expects," "intends," "plans," "anticipates," "believes," "estimates," "predicts," "projects," "potential," "continue," "preliminary," and similar expressions, or the negative of these terms. These forward-looking statements include, but are not limited to, statements about the Company's expectations regarding its preliminary financial results, the timing of completion of its quarter-end financial close process for the quarter ended June 30, 2025, and its ability to file the Form 10-Q within the five calendar-day period permitted pursuant to Rule 12b-25. Forward-looking statements are based on management's current expectations based on information currently available to the Company, and are subject to known and unknown risks, uncertainties and assumptions, and actual results or outcomes may differ materially from those expressed or implied in the forward-looking statements due to various important factors, including, but not limited to the risk that the Company's financial closing procedures may not be completed within the anticipated timeframe to timely file the Form 10-Q in accordance with Rule 12b-25, as well as other risks and uncertainties discussed under the caption "Risk Factors" in the Company's most recent Annual Report on Form 10-K for the year ended December 31, 2024, Quarterly Report on Form 10-Q for the quarter ended March 31, 2025, and in any of its subsequent filings with the SEC. All forward-looking statements speak only as of the date of this Notification of Late Filing on Form 12b-25, and the Company disclaims any obligation or undertaking to update or revise any forward-looking statements contained herein, other than to the extent required by law.
