inTEST ANNOUNCES PRELIMINARY RESULTS FOR SECOND QUARTER 2010;
COMPANY TO HOLD INVESTOR CONFERENCE CALL ON AUGUST 11, 2010

CHERRY HILL, NJ, July 27, 2010 - inTEST Corporation (Nasdaq: INTT), an independent designer, manufacturer and marketer of semiconductor automatic test equipment (ATE) interface solutions and temperature management products, today announced preliminary, selected unaudited results for the quarter ended June 30, 2010, which are subject to change. The news release announcing final results for the quarter ended June 30, 2010 is expected to be disseminated on Wednesday, August 11, 2010, after the market close.

Net revenues for the quarter ended June 30, 2010 were approximately $15.3 million, compared to $9.5 million for the first quarter of 2010. Net income for the quarter ended June 30, 2010 was approximately $3.1 million or $0.30 per diluted share, compared to $1.1 million or $0.11 per diluted share for the first quarter of 2010.

Bookings for the quarter ended June 30, 2010 were approximately $12.2 million, compared to $14.0 million in bookings for the first quarter of 2010.

Robert E. Matthiessen, President and Chief Executive Officer of inTEST commented, "Our business continues to perform at quarterly revenue levels not seen in several years, with quarterly net income approaching an historic high for our company given the operating leverage now in our business. While bookings were a multiple higher than the $4.6 million in the year ago period, we did experience a slight pullback in bookings in the second quarter compared to the first quarter of 2010. Within the quarter over quarter number, we believe the slight decline is a direct result of some pull-in of bookings at the end of the first quarter that would normally have been in the second quarter. As a result of the reduced bookings in the second quarter, we currently expect net revenues and net income for the third quarter ended September 30, 2010 will be between the levels achieved in the first and second quarters of 2010. Overall, we remain optimistic in our business outlook but expect there will be some variability in results as we move forward given our recent strong operating levels."
