H.B. Fuller Comments on Third Quarter Earnings

and Revises Full Year Guidance

ST. PAUL, Minn. - H.B. Fuller Company (NYSE: FUL) today announced that net income for the third quarter ended August 28, 2004 is expected to be $0.32 to $0.34 per share (diluted). The primary reasons for the reduced net income compared to the third quarter of 2003 are the rate of rapidly rising raw material costs exceeding selling price increases, higher than expected operating expenses for bad debt and legal settlements, partially offset by a favorable tax settlement. The fourth quarter’s net income is expected to see improvement over that of the previous year’s fourth quarter, as selling price increases implemented earlier begin to be realized.

Due to the third quarter results and the continuing volatility of raw material pricing and supply, full year net income for fiscal year 2004 is expected to be lower than the original guidance given earlier this year.

Third quarter results will be released after the market close on Tuesday, September 21, 2004. H.B. Fuller will host a conference call on September 22, 2004 at 9:30 a.m. central time (10:30 a.m. eastern time). The call can be heard live over the Internet at H.B. Fuller’s website at www.hbfuller.com, under shareholder relations, or at www.streetevents.com.
