Bank First announces plans to construct a 13,100 sq. ft. Operations Center in Manitowoc

MANITOWOC, WI, August 11, 2021 - Bank First (NASDAQ: BFC) ("Bank First") is pleased to announce its plans to construct a new, environmentally-friendly Operations Center. The new 13,100 square foot facility will be located on the 8.74 acre lot in the industrial park at the corner of Dufek Drive and West Drive in Manitowoc.

Bank First has experienced exponential growth over the past decade, with its asset size climbing from $910 million in 2011 to $2.8 billion today. In the daily pursuit to keep its promise to be a relationship-based community bank focused on providing innovative products and services that are value driven, the bank anticipates this increase to continue and has sought ways to accommodate the additional staff necessary to sustain its growth.

"We are thrilled to officially announce plans to build our new Operations Center," stated Mike Molepske, CEO of Bank First. "The addition of this new facility is essential for our future. With our overall rapid bank growth over the past several years, we have simply outgrown our current space for our operations team in Manitowoc. This center will allow us to centralize a majority of our operations staff while continuing to provide exceptional service for our customers."

The bank's new Operations Center will feature all LED lighting and will be constructed through a variety of environmentally-friendly methods and systems including the use of carbon-reducing building materials. The HVAC (heating, ventilation, and air conditioning) system will include monitored controls to promote efficiency as well ionizing equipment to assist in eliminating germs and bacteria. Office furniture will consist of SmartTM Ocean chairs made from recycled fishing nets, Terra-Turf flooring made from recycled tires, and Stampino field tile made from 40% pre- consumer recycled content, just to name a few. The property currently hosts a natural landscape of plants and grasses which the bank plans to preserve and maintain. External designs also include a perimeter walking path to encourage employee wellness.

Interior designs for the center include 66 work stations, six offices, four multi-function rooms, and will house the bank's loan operations department as well as the option to include other departments. While the initial project includes plans for a 13,100 square foot office, space for two 6,000 square foot additions is reserved for planned future use.

Site work will begin in early fall of 2021 with construction to begin in early spring of 2022. Stauss Architect, LLC is assisting in the design and planning process and Jos. Schmitt Construction will be serving as the General Contractor for the project.
