MADISON, Wis., June 17, 2014 (GLOBE NEWSWIRE) — First Business
Financial Services, Inc. (Nasdaq:FBIZ) expects to join the Russell
2000(R) Index when Russell Investments reconstitutes its comprehensive
set of U.S. and global equity indexes on June 27, 2014, according to a
preliminary list of additions posted June 13, 2014 on
www.russell.com/indexes.

Annual reconstitution of Russell’s U.S. indexes captures the 4,000
largest U.S. companies as of the end of May, ranking them by total
market capitalization. The Russell 3000(R) Index measures the
performance of the 3,000 largest U.S. companies. The largest 1,000
companies in this ranking comprise the Russell 1000(R) and the next
2,000 companies comprise the Russell 2000(R). Membership in the Russell
2000(R), which remains in place for one year, means automatic inclusion
in the appropriate growth and value style indexes. Russell determines
membership for its equity indexes primarily by objective,
market-capitalization rankings and style attributes.

“We are very pleased to announce our expected addition to the Russell
2000(R) Index. We believe that our inclusion will further increase our
exposure to investors and the financial community, allowing us to
broaden our shareholder base,” said Corey A. Chambas, President and
Chief Executive Officer. “We are excited for investors to learn about
and benefit from our impressive growth prospects and historical
shareholder returns.”

Following June 30, 2014, First Business is also expected to remain in
the Russell Microcap(R) Index which consists of the smallest 2,000 of
the 4,000 U.S. companies captured in Russell’s U.S. indexes. First
Business’ market capitalization as of May 31, 2014 was $181 million, an
increase of $65 million, or 56%, from May 31, 2013.

Russell indexes are widely used by investment managers and
institutional investors for index funds and as benchmarks for active
investment strategies. These investment tools originated from Russell’s
multi-manager investment business in the early 1980s when the company
saw the need for a more objective, market-driven set of benchmarks in
order to evaluate outside investment managers.
