Other Events.

As previously disclosed, on May 12, 2026, NSTS Bancorp, Inc. (the “Company”) and Brookfield Bancshares, Inc. (“Brookfield”) entered into an Agreement and Plan of Merger (the “Merger Agreement”), pursuant to which the Company will be merged with and into Brookfield, and the Company’s subsidiary bank, North Shore Trust and Savings (the “Bank”), will become a wholly-owned subsidiary of Brookfield and continue to operate under its existing name and federal savings association charter as a subsidiary of Brookfield.

As part of the merger transaction, the parties agreed that, on or prior to the closing of the merger, the Bank would divest of its mortgage lending division, Oak Leaf Community Mortgage (“OLCM”), which operated in three locations in the north and western suburbs of Chicago. As of June 1, 2026, 12 employees are no longer with the Company, with an additional four employees expected to leave prior to, or at, August 3, 2026.

Effective June 1, 2026, the Bank divested OLCM by transferring certain assets utilized by OLCM, including certain real estate leases, third party vendor contracts, trademark rights and other information technology assets to an unaffiliated national mortgage lender, and a substantial majority of the OLCM employees were hired by that mortgage lender.

The Company does not expect to recognize any material gain or loss or incur any material expenses as a result of the OLCM divestiture.
