RPM Reports Record Third Quarter Results

• Sales increase 19%

• Excluding asbestos charges, earnings increase 53%

• Record earnings anticipated for full fiscal year 2006, excluding asbestos charges

MEDINA, OH – April 6, 2006 – RPM International Inc. (NYSE: RPM) today reported record sales of $612.5 million for its fiscal third quarter ended February 28, 2006, an 18.6% increase over sales of $516.3 million in the year-ago third period.

RPM’s third-quarter 2006 net loss for the seasonally-weak third quarter was $2.7 million, a 43.7% improvement versus the year-earlier loss of $4.8 million. The loss per diluted share improved by 50.0%, to ($0.02) from ($0.04). Both periods include $15.0 million in pre-tax reserve charges for asbestos liability. Excluding the asbestos charges, RPM’s third-quarter 2006 net income was up 52.6% to $6.9 million, from $4.5 million a year ago, and earnings per diluted share grew 50.0% to $0.06 from $0.04.

Third-quarter earnings before interest and taxes (EBIT) were $4.7 million compared with EBIT of $0.8 million a year ago. Excluding asbestos charges, EBIT grew 24.2%, to $19.7 million from $15.8 million in the 2005 third quarter.

“We continue to be encouraged by what we’re seeing in our top line,” said Frank C. Sullivan, president and chief executive officer. “Strong demand continues to drive organic sales throughout the business, producing 10.0% of our growth this quarter. Acquisition growth was 9.0%, reflecting mainly the purchase of illbruck Sealant Systems (“illbruck”) on August 31, 2005, as well as the sale of Thibaut Inc. on January 11, 2006,” he said.

“During this period, RPM’s gross margins began to recover as our own higher pricing was able to offset higher raw material costs, many of which have begun to moderate. With strong sales momentum carrying into our fourth quarter and with our margins recovering, we expect to achieve record sales and earnings for the full fiscal year ending May 31, 2006, excluding asbestos charges,” stated Sullivan.

Third-Quarter Segment Sales and Earnings

Sales for RPM’s industrial segment grew 29.0%, to $378.3 million in the fiscal 2006 third quarter from $293.1 million a year ago. Of this increase, 15.9% was the result of the illbruck acquisition and four smaller acquisitions. Organic growth for this segment was 14.2%, reflecting continued strong demand across all industrial markets. Foreign exchange differences reduced industrial sales growth by 1.1% during the third quarter. Industrial EBIT increased 47.7% for the quarter, to $18.1 million from $12.2 million a year ago.

Consumer segment sales increased 4.9%, reflecting solid organic growth of 6.1%, partly offset by the sale of Thibaut and foreign exchange differences. Almost every consumer segment product line participated in 5% or higher sales growth during the quarter. RPM’s consumer segment EBIT grew 13.9%, to $14.7 million in the 2006 third quarter from $12.9 million a year ago.

RPM’s corporate/other segment expenses before interest and taxes increased $3.8 million over the 2005 second quarter, reflecting primarily higher health care costs for the company’s U.S. and Canadian employees. Despite this increase, total SG&A expenses improved, declining to 36.7% of sales from 37.8% a year ago.

Asbestos Liability

The company took an additional $15.0 million pre-tax charge in the third quarter to increase its asbestos liability reserves, which now total $99.2 million on RPM’s balance sheet. The charge for this third quarter matches a similar charge taken a year ago. On a year-to-date basis, RPM has taken $45.0 million in pre-tax charges to increase asbestos liability reserves, compared with $62.0 million in the first nine months of fiscal 2005. Before tax asbestos-related payments were $17.1 million in the third quarter, bringing total payments for the first nine months of fiscal 2006 to $47.0 million, which compares favorably to $56.3 million paid during the first nine months of fiscal 2005. During the quarter, the company retained a third-party consultant to assist in a review of its potential liability for future, unasserted asbestos claims and expects to complete this evaluation in the coming months.

“While asbestos remains a challenge, we are pleased with our year over year progress in managing this issue, which has resulted in reduced settlement costs, increased dismissal rates, and lower total costs on an annual basis. Our defense strategy, coupled with the benefit of an improving legal environment at the state level and greater scrutiny of the abuses inherent in this litigation at several levels, should continue to favorably impact our annual costs,” Sullivan said.

Business Transactions

During the third quarter, two RPM business units made acquisitions to further their market penetration. Both are expected to be accretive to earnings within a year.

On January 1, 2006, Euclid Chemical Company, part of RPM’s Tremco Group, acquired Tamm’s Industries, a $20.0 million producer of high-performance restoration, protection and waterproofing products for the concrete construction industry.

On February 13, 2006, DAP acquired Custom Building Products’ ready-to-use (pre-mix) patch and repair product line, further extending DAP’s product line.

On January 11, 2006, RPM sold its non-core Thibaut Inc. wallcovering business to its management and The Riverside Company, a private equity firm.

Cash Flow and Financial Position

Cash generated by RPM operations amounted to $111.4 million through the first nine months of fiscal 2006, up 29.9% from $85.7 million a year ago. Capital expenditures to date in 2006 were $31.2 million, compared with depreciation of $40.9 million during the same period. RPM’s total debt was $879.5 million at the end of the third quarter, compared to $838.0 million at the end of fiscal 2005. The increase is due primarily to acquisition costs, mainly illbruck, offset by the retirement of $150.0 million in 7.0% bonds that matured on June 15, 2005. As of February 28, 2006, RPM’s debt-to-capitalization ratio was 45.0% compared with 44.7% at May 31, 2005 and 45.0% one year ago.

Nine-Month Sales and Earnings

For the first nine months of fiscal 2006, net sales increased 16.5%, to $2.1 billion from $1.8 billion a year ago. Nine-month EBIT increased 11.7% to $128.4 million from $114.9 million a year ago. Nine-month net income was up 11.9% to $65.8 million from $58.8 million in the prior year. Diluted earnings per share were $0.54, up 12.5% from $0.48 earned in the first nine months of 2005.

Excluding asbestos charges, nine-month 2006 net income of $94.5 million declined 3.0% from 2005 nine-month net income of $97.5 million, EBIT declined 2.0% to $173.4 million from $176.9 million and diluted earnings per share declined 3.8% to $0.76 from $0.79. These declines are principally the result of the impact of the Gulf Coast hurricanes last fall and the $10.2 million ($0.05 per diluted share) of one-time costs incurred during this year’s second quarter, mostly related to the September 2005 finalization of the Dryvit national residential class action settlement.

Industrial segment sales grew 24.5% during this year’s first nine months, to $1.27 billion from $1.02 billion in fiscal 2005. Of this growth, 13.1% was organic and 11.3% was acquisition-related. The segment’s EBIT for the period increased 17.3%, to $134.1 million from $114.3 million.

Consumer segment sales grew organically 6.0%, to $824.5 million from $777.8 million in the first nine months of fiscal 2005. EBIT declined 3.8%, to $87.0 million from $90.4 million a year ago, due primarily to net higher raw material costs not fully offset by higher selling prices.

Business Outlook

“Business conditions remain strong, evidenced by our unit sales growth, which continues to build. We are gaining relief from the sharp raw material cost increases we’ve been experiencing, as reflected by the third quarter’s improving gross margins. Following the negative impact of hurricanes in our second quarter, Gulf Coast rebuilding efforts already have become a slight positive for RPM in the third quarter, and will likely continue to boost sales through this year. All of these improvements, coupled with the passage of one-time cost events that uniquely impacted this year’s second quarter, bode well for a strong finish to this year, with continued momentum into 2007,” Sullivan said.

(a)	Adjusted figures presented remove the impact of the additional asbestos charges taken during each period presented.
(b)	The presentation includes a reconciliation of Income (Loss) Before Income Taxes, a measure defined by Generally Accepted Accounting Principles (GAAP) in the United States, to EBIT.
(c)	EBIT is defined as earnings (loss) before interest and taxes. We evaluate the profit performance of our segments based on income before income taxes, but also look to EBIT as a performance evaluation measure because interest expense is essentially related to corporate acquisitions, as opposed to segment operations. We believe EBIT is useful to investors for this purpose as well, using EBIT as a metric in their investment decisions. EBIT should not be considered an alternative to, or more meaningful than, operating income as determined in accordance with GAAP, since EBIT omits the impact of interest and taxes in determining operating performance, which represent items necessary to our continued operations, given our level of indebtedness and ongoing tax obligations. Nonetheless, EBIT is a key measure expected by and useful to our fixed income investors, rating agencies and the banking community all of whom believe, and we concur, that this measure is critical to the capital markets’ analysis of our segments’ core operating performance. We also evaluate EBIT because it is clear that movements in EBIT impact our ability to attract financing. Our underwriters and bankers consistently require inclusion of this measure in offering memoranda in conjunction with any debt underwriting or bank financing. EBIT may not be indicative of our historical operating results, nor is it meant to be predictive of potential future results.
