P.A.M. Transportation Services Set to Join Russell Global and Russell 3000

TONTITOWN, Ark., June 24, 2014 (GLOBE NEWSWIRE) -- P.A.M. Transportation
Services, Inc. (Nasdaq:PTSI) today announced that it is set to join the
broad-market Russell^® 3000 ^ Index and the Russell Global 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
on June 13, 2014, on www.russell.com/indexes.

Annual reconstitution of Russell's U.S. indexes captures the 4,000 largest
U.S. stocks as of the end of May, ranking them by total market capitalization.
Membership in the Russell 3000, which remains in place for one year, means
automatic inclusion in the large-cap Russell 1000^® Index or small-cap Russell
2000^® Index as well as the appropriate growth and value style indexes.
Russell determines membership for its equity indexes primarily by objective,
market-capitalization rankings and style attributes.

The Russell 3000 also serves as the U.S. component to the Russell Global
Index, which Russell launched in 2007.

Russell indexes are widely used by investment managers and institutional
investors for index funds and as benchmarks for active investment strategies.
Approximately $5.2 trillion in assets are benchmarked to the Russell Indexes.
Russell calculates more than 700,000 benchmarks daily covering approximately
98 percent of the investable market globally, more than 80 countries and
10,000 securities. 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.
