There will be no physical location for the Annual Meeting. You will be able to attend and participate in the Annual Meeting online and vote your shares electronically. In addition, although the live webcast is available only to stockholders at the time of the meeting, following completion of the Annual Meeting, a webcast replay will be posted as soon as practicable to our Investor Relations section of our website athttps://ir.pfholdingscorp.com.

The matters expected to be acted upon at the Annual Meeting are described in the accompanying Proxy Statement (“Proxy Statement”). The Annual Meeting materials include the Proxy Statement, our annual report on Form 10-K for the fiscal year ended December 31, 2024 (the “Form 10-K”) and the Proxy card, each of which is enclosed (collectively, the “Proxy Materials”).

Only stockholders of record at the close of business on April 14, 2025 may vote at the Annual Meeting and any postponements or adjournments of the meeting. All stockholders are cordially invited to participate in the Annual Meeting and any postponements or adjournments of the meeting. However, to ensure your representation at the Annual Meeting, please vote as soon as possible by using the internet or telephone, as instructed in your Proxy Materials.
