Status of our Principal Accountant

On March 6, 2026, our audit committee of the board of directors (the "Audit Committee") engaged Forvis Mazars, LLP ("Forvis") as our independent registered public accounting firm for the year ended December 31, 2026. We previously disclosed that our independent registered public accounting firm for the year ended December 31, 2025 declined to stand for re-election.

In deciding to select Forvis, the Audit Committee reviewed auditor independence issues and existing commercial relationships with Forvis and concluded that Forvis has no commercial relationship with us that would impair its independence. During our fiscal years ended December 31, 2025 and 2024, and through the subsequent period prior to engaging Forvis, neither we nor anyone acting on our behalf consulted with Forvis regarding any of the matters or events described in Items 304(a)(2)(i) and (ii) of Regulation S-K.
