REPORTS CORRECTION TO FIRST QUARTER FINANCIAL RESULTS

Bedminster, N.J. – April 22, 2026 – Peapack-Gladstone Financial Corporation (NASDAQ Global Select Market: PGC) (the "Company") reported its first quarter 2026 financial results in its press release (the “Earnings Release”) and a supplemental investor presentation (the “Investor Presentation”), each of which were dated April 22, 2026. Subsequent to the issuance of the Earnings Release, the Company identified an error in the calculation of its reported book value per share and tangible book value per share and related capital ratios. The error relates to the treatment of the preferred stock issuance that occurred in March 2026, which should have been deducted when calculating book value per share and tangible book value per share.

Accordingly, as of March 31, 2026:

• Book value per common share has been revised from $39.48 to $37.79;
• Tangible book value per common share has been revised from $37.02 to $35.33; and
• Tangible equity to tangible assets has been revised from 8.56% to 8.17%.

This correction does not impact any other information in the Earnings Release or the Investor Presentation, including the Company’s reported net income, operating results, cash flows, or regulatory capital ratios for the period.
