FOR IMMEDIATE RELEASE   Bank First National Corporation becomes SEC registered   •  Ticker symbol changes from ‘BFNC’ to ‘BFC’    •  Stock traded on NASDAQ    •  Subsidiary changes name to Bank First, N.A.     Manitowoc, Wis, October 23, 2018 – Bank First National Corporation (NASDAQ: BFC), is pleased to announce it has secured regulatory approval from the U.S. Securities and Exchange Commission (SEC) to become a fully reporting public company. In addition, the company has obtained approval to begin trading its stock on the NASDAQ Capital Market under the ‘BFC’ ticker symbol.

MICHAEL MOLEPSKE

“Becoming an SEC registered company represents a major milestone for Bank First,” stated Michael Molepske, President and Chief Executive Officer of Bank First National Corporation. “As a result of the hard work and dedication of our remarkable team of bankers, we have become one of the top performing banks in the State of Wisconsin, allowing us to create an incredible earnings growth story and providing superior shareholder returns. We continue to focus on growing our institution organically and through bank acquisitions. Bank First has recently added relationship minded business bankers in our Oshkosh, Appleton, Waupaca and Sheboygan offices. In addition, Bank First continues to search for community banks to acquire. Our listing on Nasdaq provides the institution with the financial credibility and necessary currency to assist us in that pursuit.”

In addition to increasing the liquidity of its stock, registering with the SEC will bring Bank First greater visibility and credibility before financial markets and investors. It will also provide the company with additional sources of capital and the flexibility to execute efficiently when a strategic opportunity arises.

Along with registering with the SEC, the company’s subsidiary, Bank First National, formally changed its name to Bank First, N.A. “Changing our name to Bank First (i.e. removing ‘National’) supports our strategic initiative to further differentiate ourselves from similarly named banks and strengthens our brand positioning in the marketplace with a name that is more distinctive and recognizable,” stated Molepske.

With $1.74 billion in assets, the company continues to strengthen its position as a top-performing community bank at the state and national level. Bank First National Corporation has reported record earnings year-over-year since 2010, and shareholders have enjoyed superior financial returns as a result. This is evidenced in the following graph, which compares the yearly cumulative total return on the company’s common stock measured at each of the last five year ends and through September 30, 2018 with the KBW Regional Banking Index. The KBW Regional Banking Index (KRX) seeks to reflect the performance of U.S. companies that do business as regional banks or thrifts. The cumulative returns set forth in the graph assume an initial investment of $100.00 was invested in the common stock of the company and the KBW Regional Banking Index on December 31, 2012, and that all dividends were reinvested into additional shares of the same class of equity securities at the frequency with which dividends were paid on such securities during the applicable comparison period.
