Chase Corporation Announces Increases in Fourth Quarter Revenue and Net Income of 13% and 16% as Compared to Last Year; The Company Also Announced a Dividend of $0.35 Per Share.

BRIDGEWATER, Mass. -- Chase Corporation (AMEX:CCF) today reported revenues of $91,389,000 for the fiscal year ended August 31, 2005 compared with $87,084,000 for the same period last year. Net income for the fiscal year was $4,788,000 or $1.23 per diluted share compared to $4,627,000 or $1.16 per diluted share in the prior year. Income before income (loss) on minority interest, legal settlement, and impairment of goodwill was $5,179,000 or $1.33 per diluted share for the period ended August 31, 2005 compared to $5,680,000 or $1.42 per diluted share in the prior year period. Fourth quarter fiscal 2005 revenues were $25,584,000 with net income of $2,011,000 versus revenues of $22,718,000 and net income of $1,736,000 for the like period last year.

On June 14, 2005, the Company filed a stipulation of dismissal with prejudice resolving outstanding litigation with Tyco Adhesives arising out of Tyco's allegations that the Company had improperly used Tyco trade secrets and confidential information. In a settlement agreement effective June 5, 2005, the Company and two of its former employees settled the matter prior to trial for a cash payment of $520,000 to avoid a prolonged and expensive trial. The settlement released the Company as well as the two former employees for liability for all past actions.

During fiscal 2004, a goodwill impairment charge of $579,000 was taken as a result of the Company's December 2003 sale of its Sunburst Electronics Manufacturing Solutions, Inc. subsidiary ("Sunburst") (See December 12, 2003 press release). Additionally, the Company had determined that the fair value of its unconsolidated joint venture was less than the book value, thus requiring an impairment charge of $500,000 in the first quarter of fiscal 2004.

Also announced today was the completion of our acquisition of Concoat Holdings, Ltd. of Camberly, Surrey, England for cash on October 14, 2005. This acquisition will strengthen our conformal coatings business and serve as a foundation for Chase in Europe. Concoat had been our agent, distributor and manufacturing licensee for over 25 years.
