[For Immediate Release]

Bank First Corporation Announces Retirement

of Board Director Stephen Johnson

MANITOWOC, WI,

June 16, 2026 -- Bank First Corporation (NASDAQ: BFC), the

holding company of Bank First, announces the retirement of Stephen E. Johnson from its Board of Directors, effective June 15,

2026.

Mr. Johnson joined the Board in January 2019

and brought decades of leadership experience in both the financial services and insurance industries. During his tenure, he served on

the Audit, Compensation, Governance and Nominating, Loan, and Community Reinvestment Act “CRA” Committees. He brought a thoughtful

perspective on risk, compliance, lending, and community reinvestment to Board discussions, helping guide the Bank’s strategic direction

and governance.

STEPHEN E. JOHNSON

“Steve’s steady leadership and practical

insight have made a meaningful impact on our organization,” said Mike Molepske, Chief Executive Officer and Chairman of the Board

at Bank First. “His commitment to relationship-based banking and strong governance perspective helped guide our continued growth.

We are grateful for his service.”

Mr. Johnson previously served as Market President

and CRA Officer for Bank First. Prior to joining the Bank, he was the Director of Compliance for First National Bank of Waupaca from 2016

to 2017 and served as Chairman of the Board of First National Bank of Waupaca as well as Waupaca Bancorporation, Inc. Before entering

the banking industry, he spent more than 35 years with Sentry Insurance A Mutual Company, serving in a variety of leadership positions

across operations, underwriting, marketing, and strategic planning.

A strong advocate for community involvement, Mr. Johnson

has maintained deep ties to the Waupaca area. He has supported numerous organizations, including the Waupaca County Emergency Food and

Shelter Program and the Western Golf Association/Evans Scholars Foundation. He has also served on several boards, including the ThedaCare

Foundation of Waupaca, the ThedaCare Family of Foundations, the Waupaca Area Community Foundation, and the School District of Waupaca

Board of Education.

Bank First extends its gratitude to Mr. Johnson

for his leadership and the meaningful impact he made throughout his years of service.
