Wabash National Hiring Needs Grow

LAFAYETTE, Ind. — May 3, 2010 — Wabash National Corporation (NYSE: WNC) today announced that based on current demand levels the need for additional hires continues to grow.

"We not only met our plans announced earlier this year to have increased hourly staffing by 190 associates by the end of the first quarter, but have far exceeded that projection as order backlog has continued to grow,"said Dick Giromini, President and CEO of Wabash National Corporation."With our current outlook, we expect that by the end of May, to have added upward of 500 associates since the beginning of the year."

"Recognizing that we are still in the early stages of an industry recovery, we are continuing to take the prudent route in filling our near-term staffing needs with temporary-status associates,"said Brent Yeagy, Vice President and GM of Transportation Products Group."Once we believe that the recovery is sustainable we will evaluate the opportunity to convert a number of those hired to full-time status."
