IONICS REPORTS FIRST QUARTER RESULTS

Watertown, MA, May 6, 2003 . . . Ionics, Incorporated (NYSE-ION) today reported first quarter revenues, net income, and earnings per share for the period ended March 31, 2003. Revenues for the quarter were $88.2 million compared to $80.0 million for the first quarter of 2002. Net income of $576,000 and earnings per share of $0.03 for the quarter compared to net income of $1.5 million and earnings per share of $0.08 for the comparable period in the prior year. Backlog at the end of the quarter was $348.5 million, compared to $249.6 million one year earlier.

Arthur L. Goldstein, Chairman and Chief Executive Officer, noted that the results reflected revenue improvement in each of the Company's business groups (including sales to affiliated companies) as well as an increase in gross margin of $2.3 million compared to the first quarter of 2002. An increase in selling and administrative costs, due primarily to higher post-retirement and pension costs, as well as higher professional service fees, essentially offset the increase in gross margin.

Ionics will broadcast its first quarter financial results conference call via the internet today at 10:00AM, EDT. This conference call will be accessible on the Company's website at www.ionics.com. A recorded replay of the conference call will also be accessible on our website for a two-week period commencing at 5:00PM today. In addition, this press release will also be accessible on our website promptly following its issuance.

Ionics is a global separations technology company involved in the manufacture and sale of membranes, equipment and own and operate services for the purification, disinfection, concentration, treatment and analysis of water, wastewater and ultrapure water. Over a period of more than 50 years Ionics has built more desalination plants than any company in the world.
