Filing notes and footnotes

Explanation of responses 2 footnotes

Footnote F1

This line item does not reflect a new or revised holding. Rather, it is being reported again in order to gain access to the electronic filing system. The purpose of this amendment to the Form 3 filed by the Reporting Persons on October 21, 2025 is to replace Footnote 2 set forth therein as provided in Footnote 2 herein. For the avoidance of doubt, the Reporting Persons have not engaged in any transactions in the securities of the Issuer since the initial Form 3 was triggered on October 17, 2025.

Footnote F2

As of October 21, 2025, the Schedule 13(d) group no longer collectively beneficially owned more than 10% of the Issuer's outstanding shares of Common Stock. Later in the day on October 21, 2025, another member of the Schedule 13(d) group engaged in additional transactions in securities of the Issuer that resulted in the Schedule 13(d) group once again collectively beneficially owning more than 10% of the Issuer's outstanding shares of Common Stock. Subsequently, on November 4, 2025, the Schedule 13(d) group was terminated, and the Reporting Persons are no longer members of a Schedule 13(d) group that collectively beneficially owns more than 10% of the Issuer's outstanding shares of Common Stock.
