Harleysville, PA, May 20 - Raymond J. De Hont, President and Chief Executive Officer of Met-Pro Corporation (NYSE - "MPR"), today announced sales and earnings per share for the first quarter ended April 30, 2003.

Sales for the first quarter were $17.0 million, which was 5% above last year´s first quarter sales of $16.2 million.

Net income for the first quarter ended April 30, 2003 totaled $1.4 million compared to $1.2 million for the same quarter of last year, an increase of 12%. This increase was due to higher gross margins enjoyed in the Company´s Product Recovery/Pollution Control Equipment segment combined with continuing cost reductions in both segments.

Basic and diluted earnings per share were up $.02 to $.22, an increase of 10% over the $.20 earned during last year´s first quarter.

Cash flows from operating activities increased to $2.4 million, a 160% increase over the $0.9 million reported in the first quarter ended April 30, 2002. Cash flows from operating activities per share for the first quarter increased $.24 to $.39, up 160% over the $.15 earned during the first quarter ended April 30, 2002.

Bookings of new orders for the first quarter ended April 30, 2003 totaled $18.7 million compared to $15.6 million for the same period of last year, or an increase of 20%.

This increase in bookings resulted in a 22% increase in the backlog of booked and unbooked orders awaiting drawing approval to $17.4 million compared to $14.3 million for the first quarter ended April 30, 2002. A high percentage of this backlog is scheduled to be shipped during the current fiscal year.

In making this announcement, De Hont stated, “while it is difficult to predict the future of the economy, the first quarter results continue to demonstrate and reinforce our confidence in the ability of our employees and our products to successfully compete during difficult times. As a result of our continuing cost cutting efforts, we are well positioned to deliver higher earnings as our sales increase”.
