Perficient Set to Join Russell Microcap Index

AUSTIN, Texas, June 13, 2005 --Perficient, Inc. (NASDAQ: PRFT), a leading information technology consulting firm in the central United States, today announced it will join the new Russell Microcap Index when the Russell Investment Group reconstitutes its family of U.S. indexes on June 24. Russell recently posted a preliminary membership list at www.russell.com/indexes.

The Russell Microcap Index, which will be comprised of the smallest 1,000 securities in the small-cap Russell 2000® Index plus the next 1,000 companies, is based on a ranking of all U.S. equities by market capitalization. This new index offers managers and other investors a comprehensive, unbiased barometer to compare their performance against the genuine microcap marketplace of stocks.

“We’re pleased to be named to the Russell MicroCap Index,” said Perficient chairman and chief executive Jack McDonald. “This will increase Perficient’s visibility with investors and institutions that rely on the Russell Indexes as a key part of their investment strategy.” Russell Indexes are widely used by investment managers for index funds and as benchmarks for both passive and active investment strategies. The index reconstitution process is followed closely by many investors because the Russell indexes currently have $2.5 trillion in assets benchmarked to them. Investment managers who oversee these funds purchase shares of member stocks according to the company’s weighting in the particular index.

Companies slated for the Russell Microcap were ranked as of May 31 by total market capitalization and weighted based on free-float adjustment, an integral aspect of Russell index methodology. Free-float adjustment means stocks are weighted by their available market capitalization, which is calculated by multiplying the primary closing price by the available shares.

The preliminary lists of additions and deletions represent the first public step in Russell's annual "reconstitution" process. Any updates to these lists will be posted June 17 and June 24. Updates are made primarily due to recent corporate actions that affect the stock and availability of it shares. Otherwise the preliminary list remains largely unchanged.
