Dear Fellow Shareholder:
You are cordially invited to attend the 2018 annual meeting of shareholders of First Business Financial Services, Inc. (the “Company”), which will be held at 5:00 P.M., local time, on Tuesday, May 22, 2018 at the Madison Marriott West located at 1313 John Q Hammons Drive, Middleton, Wisconsin 53562. At the annual meeting, we will review the Company’s activities during the past year and shareholders will be given an opportunity to address questions to the Company’s management.
We are using the Securities and Exchange Commission (“SEC”) rule that allows us to furnish proxy materials to shareholders over the Internet. On or about April 6, 2018, we will begin mailing a Notice of Internet Availability of Proxy Materials (“Notice”) to our shareholders informing them that our Proxy Statement and the 2017 Annual Report on Form 10-K along with voting instructions, are available online. This means that our shareholders will receive only the Notice containing instructions on how to access the proxy materials over the Internet and vote online. If you receive this Notice, but would still like to request paper copies of the proxy materials, please follow the instructions on the Notice or on the website referred to in the Notice. On or about April 20, 2018, we will also mail a proxy card to all registered shareholders, but not the proxy materials, which will allow voting of shares by completing and returning the proxy card. By delivering proxy materials electronically to our shareholders, we can conserve natural resources and reduce the costs of printing and distributing the proxy materials, while providing our shareholders with access to the proxy materials in a fast, easily accessible and efficient manner.
The Board of Directors of the Company recommends that you vote your shares “FOR” all the nominees listed in proposal one and “FOR” proposals two and three.
Your continued support is appreciated and we hope you will attend the annual meeting. Whether or not you are personally present, it is very important that your shares are represented at the meeting. Accordingly, please vote your shares by following the instructions on the Notice. Your vote is important. Please join us and the Board of Directors in supporting these proposals.
Sincerely,
/s/Jerry Smith /s/Corey Chambas
Jerry Smith Corey Chambas
Chair of the Board President and Chief Executive Officer
