ELI LILLY & Co

(a)Evaluation of Disclosure Controls and Procedures. Under applicable SEC regulations, management of a reporting company, with the participation of the principal executive officer and principal financial officer, must periodically evaluate the company's "disclosure controls and procedures," which are defined generally as controls and other procedures of a reporting company designed to ensure that information required to be disclosed by the reporting company in its periodic reports filed with the SEC (such as this Quarterly Report on Form 10-Q) is recorded, processed, summarized, and reported on a timely basis.

Our management, with the participation of David Ricks, president and chief executive officer, and Lucas Montarce, executive vice president and chief financial officer, evaluated our disclosure controls and procedures (as such terms are defined in our Annual Report on Form 10-K for the year ended December 31, 2024) as of March 31, 2025, and concluded that they were effective.

(b)Changes in Internal Controls. During the first quarter of 2025, there were no changes in our internal control over financial reporting that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
