RPM’s INTERNAL GROWTH DRIVES RECORD FIRST-QUARTER SALES AND EARNINGS

• Fiscal 2005 first-quarter sales rise 14 percent

• Earnings per share increase 15 percent

MEDINA, Ohio, – October 6, 2004 – RPM International Inc. (NYSE: RPM) today announced a record quarter for sales, earnings and earnings per share for its fiscal 2005 first quarter ended August 31, 2004.

“Market demand remained solid in both our industrial and consumer segments during our first quarter,” said Frank C. Sullivan, president and CEO. “We continue to successfully supplement underlying growth with the introduction of new products and services, which are quickly gaining market acceptance.”

First-Quarter Sales and Earnings

RPM reported net sales of $661.5 million for the fiscal 2005 first quarter, a 13.9 percent increase over last year’s first quarter. Organic growth increased sales by $65.5 million, or 11.3 percent. Acquisitions, net of a small divestiture, added $8.2 million, or 1.4 percent, and net favorable foreign exchange rates contributed $6.8 million, or 1.2 percent, to the sales growth. A reclassification of co-op advertising expense was made to better conform with industry practice, which, on a comparative basis, reduced reported fiscal 2004 first-quarter net sales and selling, general and administrative expenses (SG&A) by $9.1 million. This change in classification for co-op advertising expense does not affect earnings before interest and taxes (EBIT), net income or earnings per share.

Net income reached $54.5 million, an improvement of 14.3 percent over last year’s first quarter, while diluted earnings per share rose to a record $0.47, a 14.6 percent improvement compared with the fiscal 2004 first quarter. The company elected early adoption of FAS 123 (“Accounting for Stock-Based Compensation”) effective June 1, 2004, which reduced fiscal 2005 first-quarter earnings by approximately one-half cent per share.

Consolidated EBIT increased 15.3 percent to $92.4 million compared with last year’s $80.2 million. The EBIT margin improved to 14.0 percent of sales from 13.8 percent a year ago. The margin improvement reflects strong growth in sales volume, productivity gains, cost controls, initial price increases and accretive acquisitions, which collectively more than offset the impact of higher raw material costs. The company will continue to implement price increases in an effort to recover higher raw material costs, which have negatively affected gross margins, particularly in the consumer segment.

Both operating segments grew substantially year over year during the first quarter. RPM’s industrial segment continued to benefit from the organic growth that began in the second half of fiscal 2004. Industrial segment net sales grew by 15.6 percent, of which 11.9 percent was organic, including strength in roofing services, commercial construction sealants, admixtures, exterior insulation finishing systems (EIFS), and powder coatings. The industrial segment continued to benefit from earnings leverage on strong sales, boosting EBIT by 19.3 percent.

Consumer segment net sales grew 11.8 percent compared with first-quarter 2004, with 10.5 percent of this growth being organic as strong retail demand continued nearly throughout this segment, including wood care products

and EPOXYShield® garage floor coatings. Consumer segment EBIT grew by 9.9 percent, with higher raw material costs more than offsetting this segment’s earnings leverage from the higher sales.

Reconciliations of EBIT to the most comparable Generally Accepted Accounting Principles (GAAP) measures and an explanation of how RPM uses EBIT in managing its businesses are provided in the supplemental data attached to this release.

Cash flow from operations was $41.0 million, an increase over fiscal 2004 first-quarter cash flow of $30.9 million. After-tax asbestos-related payments during the 2005 first quarter were $11.9 million versus last year’s $4.8 million; however, last year’s first quarter had the benefit of the remaining third party insurance supplement, amounting to $9.4 million. Therefore, before taxes and insurance, total asbestos-related payments of $19.0 million this year compare with $17.1 million last year. Capital expenditures of $7.4 million during the 2005 quarter compare with depreciation of $12.3 million. Total debt increased by $3.9 million, to $723.8 million, including a $4.5 million note given in a small acquisition during the 2005 quarter. The debt-to-capital ratio remained unchanged from the fiscal year ended May 31, 2004, at 42 percent, but improved from 45 percent one year ago.

Business Outlook

“We are pleased with the strong growth in our first quarter, though it is important to note that we may not be able to sustain this level of sales growth as we face tougher comparisons to the prior year in the coming quarters,” Sullivan said. “Additionally, rising raw material prices will continue to be a concern. Despite these challenges, we continue to anticipate high single-digit growth in revenues and 10 to 12 percent earnings growth for the full 2005 fiscal year.”

(a)

The presentation includes a reconciliation of EBIT to Income Before Income Taxes, a measure defined by Generally Accepted Accounting Principles (GAAP) in the United States.

(b)

EBIT is defined as earnings before interest and taxes. We believe that EBIT provides one of the best comparative measures of pure operating performance, and it is a widely accepted financial indicator used by certain investors and analysts to analyze and compare companies. EBIT is not intended to represent cash flows for the period, nor is it presented as an alternative to operating income or as an indicator of operating performance. EBIT should not be considered in isolation, but with GAAP, and it is not indicative of operating income or cash flow from operations as determined by those principles. Our method of computation may or may not be comparable to other similarly titled measures of other companies. EBIT may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results.
