Munster, Indiana—NorthWest Indiana Bancorp (OTC Pink: NWIN) (“NWIN”), the parent of Peoples Bank SB (“Peoples Bank”), announced today that it has successfully completed the previously announced acquisition of First Personal Financial Corp. (privately held, “First Personal”) and its wholly-owned subsidiary, First Personal Bank, of Orland Park, Illinois, in a stock and cash transaction. Simultaneous with the acquisition of First Personal by NWIN, First Personal Bank, the wholly-owned Illinois state chartered commercial bank subsidiary of First Personal, merged with and into Peoples Bank.

With the completion of the acquisition, Peoples Bank will have approximately $1.1 billion in assets, $745.1 million in loans and $947.7 million in deposits. The acquisition will further expand Peoples Bank’s retail banking network into the South Suburban Chicagoland market, bringing the total number of full-service Banking Centers to 19. The integration of First Personal into the Peoples Bank brand will be completed during the third quarter of 2018.

“Closing on this acquisition represents an important strategic step for Peoples Bank as we enter the South Suburban Chicagoland market. I look forward to working with Randy Schwartz, president and chief executive officer of First Personal Bank, as he joins the Peoples team and helps us continue to create value for all of our stakeholders. The combined organization remains committed to building strong customer relationships and helping the customers and communities we serve be more successful,” said Benjamin Bochnowski, president and chief executive officer.

“We are excited to establish a physical presence within Orland Park, Lemont, and Chicago (Garfield Ridge), Illinois to better serve our current customers surrounding these markets. We look forward to building on the success that Randy and his team have had over the years,” Bochnowski said. He added, “integration remains on-track for late third quarter 2018, at which point First Personal customers will have access to an expanded menu of banking services. All of the Bank’s customers will benefit from the strength of an independent community bank that continues to grow as we execute our strategic plan.”

Randy Schwartz, president and chief executive officer of First Personal Bank, has been named Chicagoland Market President at Peoples, with responsibilities in community involvement and business development in the South Suburban Chicagoland markets.
