WTC Industries, Inc. Announces Record Results for 2003

Eagan, Minnesota. WTC Industries, Inc. and its wholly owned subsidiary PentaPure Incorporated reported record total net sales of $28,304,000 in 2003. The increase of 14% from 2002 net sales of $24,882,000 was due to 23% growth in sales of original equipment and replacement filters to the appliance market, partially offset by a planned decrease in sales of iodinated resin products from $2,198,000 in 2002 to $410,000 in 2003.

Income before income taxes was $4,431,000 in 2003, an increase of 11% over $4,002,000 in 2002. Net income was $2,815,000 or $1.63 per basic share and $1.25 per fully diluted share. In 2002 net income was $7,015,000 or $4.49 per basic share and $3.19 per fully diluted share. The reason for the reduced net income in 2003 as compared to 2002 is that the income for 2002 included an income tax benefit of $3,013,000 — the result of reversing the reserve against the Company’s fully reserved deferred tax asset. The impact of this benefit was to increase the 2002 basic and fully diluted earnings per share by $1.92 and $1.37, respectively. On a pro-forma basis, assuming the Company had not received the income tax benefit and had experienced the same tax rates in 2002 as in 2003, basic and diluted earnings per share in 2002 would have been $1.62 and $1.16, respectively.

For the fourth quarter ended December 31, 2003, the Company had record net sales of $8,306,000, an increase of 47% over net sales of $5,646,000 in 2002. The increase was due to the introduction of a new line of point-of-use water filtration systems for a major customer and increased sales of original equipment and replacement filters to the appliance market.

Income before income taxes was $1,362,000 in 2003, an increase of 6% over $1,290,000 in 2002. Net income for the fourth quarter of 2003 was $912,000 compared to $2,903,000 in 2002. Basic and fully diluted earnings per share for the fourth quarter 2003 were $.51 and $.40, respectively, compared to $1.77 and $1.33 in 2002. Net income was reduced in the fourth quarter of 2003 as compared to 2002 because net income for the fourth quarter of 2002 included an income tax benefit totaling $1,613,000, the result of reversing the reserve against the Company’s fully reserved deferred tax asset. The impact of this benefit was to increase basic and fully diluted earnings per share for the fourth quarter of 2002 by $.98 and $.74, respectively. In comparing the Company’s operating performance in 2003 to 2002, it should be noted that if the Company had not received the income tax benefit

and had experienced the same income tax rates in 2002 as in 2003, pro-forma basic and diluted earnings per share for the fourth quarter of 2002 would have been $.53 and $.40, respectively. The Company is providing the pro-forma information to aid in this comparison.

Commenting on the results for both the fourth quarter and twelve months ended December 31, 2003, Mr. Jim Carbonari, President and Chief Executive Officer, said, “Our sales growth in 2003 is due to the introduction of two new filtration systems as well as increased sales of filtration systems to existing customers who are increasing the number of refrigerator models that utilize the Company’s filtration systems. Sales of replacement filters continue to increase due to the growth of the installed base of refrigerators that use the Company’s proprietary replacement filters. In December the Company launched a new line of proprietary point-of-use water filtration products for the do-it-yourself market. During 2003 the Company made significant investments in manufacturing automation to further reduce its labor costs and to meet the projected sales growth for 2004. These accomplishments have positioned PentaPure to meet its objective of becoming the market leader of water filtration products to the appliance industry.

Commenting on business conditions and the outlook for 2004, Mr. Carbonari commented, “We have set the stage for another year of sales growth. We are in the early stages of introducing a new line of refrigerator filtration systems for a major brand name appliance manufacturer that will be fully implemented by mid-year. We have plans to introduce two additional filtration systems to new appliance customers. Further rollout of the new point-of-use products to the home improvement market should have a significant impact on new product sales. Replacement filter sales should continue to have a positive impact on both sales and profitability. The Company’s investments in new automation equipment should reduce labor costs and further advance our quality objectives. New product development will continue to be a priority as we provide our customers innovative market leading products.”

Mr. Carbonari was pleased to report that the Minneapolis-St. Paul Business Journal named the Company as one of the Top 5 Fastest Growing Small Public Companies in 2003. In addition, Deloitte and Touche has named the Company one of the top 15 companies in the Minneapolis-St. Paul Technology Fast 50 and among the top 500 fastest growing technology companies in the country.

WTC Industries, Inc. designs and manufactures water filtration products for the consumer market.
