On March 30, 2021, the William Penn Bank Employee Stock Ownership Plan (the “ESOP”) completed its purchase of shares of common stock of William Penn Bancorporation (the “Company”) in the open market following the consummation of the Company’s subscription offering. The ESOP purchased 881,130 shares of Company common stock for an aggregate purchase price of $10,112,013 (including broker commissions), which did not exceed the amount that would have been paid if the full amount of ESOP shares had been purchased in the offering at $10.00 per share as disclosed in the offering prospectus. As previously disclosed, the ESOP was unable to purchase any shares of Company common stock in the subscription offering as a result of the offering’s oversubscription.
