Item 8.01
Other Events.
On February 1, 2017, First Business Financial Services, Inc. (“the “Company”) announced that Corey A. Chambas, Chief Executive Officer of the Company adopted a prearranged Rule 10b5-1 trading plan (the “Plan”) with a broker to sell up to 27,210 shares of common stock of the Company. Mr. Chambas entered into the Plan as part of his personal long-term investment strategy for asset diversification and liquidity.
Pursuant to Mr. Chambas’ Plan, the brokerage firm may sell up to 13,605 shares plus unsold shares remaining from prior selling periods during each of four selling periods beginning on March 3, 2017 and ending on December 22, 2017. Any unsold shares that remain at the end of a selling period will be carried over to the next selling period but only until December 22, 2017 at which time the Plan will terminate. Mr. Chambas will have no control over the timing of his stock sales under the Plan, and all transactions under the Plan will be reported by Mr. Chambas through individual Form 4 and Form 144 filings with the Securities and Exchange Commission.
The Plan is intended to comply with Rule 10b5-1 of the Securities Exchange Act of 1934 and the Company’s insider trading policy. Rule 10b5-1 allows corporate insiders to establish prearranged written stock trading plans.

A Rule 10b5-1 plan must be entered into in good faith at a time when the insider is not aware of material, non-public information. Subsequent receipt by the insider of material, non-public information will not prevent prearranged transactions under Rule 10b5-1 from being executed. Using a Rule 10b5-1 Plan, individuals can prudently and gradually diversify their investment portfolios over an extended period of time.
Except as may be required by law, the Company does not undertake to report on specific Rule 10b5-1 trading plans of Company officers, nor to report modifications or limitations of the Rule 10b5-1 trading plan described above or the plan of any other individual.
