Press Release Details

13 percent sales increase and strong operating margin deliver record EPS of $0.90

Donaldson Company, Inc. (NYSE: DCI) announced its financial results for its fiscal 2012 first quarter. Summarized financial results are as follows (dollars in millions, except per share data):

"We are very pleased to start our new fiscal year with another record performance," said Bill Cook, Chairman, President and CEO. "Sales in our Engine Products segment increased 18 percent as new equipment build rates at our Off-Road and On-Road OEM Customers remained robust, while continued high equipment utilization rates kept our Aftermarket Products' sales at record levels. Within our Industrial Products' segment, demand for our Torit^® dust collectors remained strong."

"Our operating margin performance was very good at 14.8 percent, another record. Our ongoing Continuous Improvement initiatives are helping us offset higher raw material costs compared to a year ago. In addition, we continue to leverage our fixed cost base as our sales grow."

"While we had a strong start to our new fiscal year, recent public forecasts for global economic growth rates have been reduced. Fortunately, our order trends remain healthy so we are retaining our original sales guidance of 7 to 15 percent growth in FY12. Of course, we will monitor business conditions at our Customers and will proactively adjust our plans if necessary. We continue to execute the Strategic Growth Plan we launched a year ago and are pleased to re-confirm our forecast of another sales record in FY12. Based on our strong 1^st quarter performance and current outlook, we have increased our FY12 EPS projection to be between $3.25 and $3.50, which would be a new record."

Financial Statement Discussion

The impact of foreign currency translation increased sales by $13.4 million, or 2.5 percent, during the first quarter compared to the same period last year. The impact of foreign currency translation increased reported net earnings by $1.3 million, or 2.5 percent, during the first quarter compared to the prior year.

Gross margin was 35.3 percent, compared to 35.0 percent in last year's first quarter. The increase came from our ongoing Continuous Improvement initiatives and selective price increases, which were partially offset by increases in our purchased raw material costs and a less favorable sales mix.

Operating expenses for the quarter were $124.6 million, or 20.5 percent of sales, versus $113.6 million, or 21.2 percent of sales, last year.

The effective tax rate for the quarter was 25.5 percent, compared to a prior year rate of 26.2 percent. Both the current and prior year's quarter included tax benefits primarily due to favorable settlements of tax audits of $4.3 million and $2.7 million, respectively.

As part of our ongoing share repurchase program we repurchased 1,376,000 shares, or 1.8 percent of our diluted outstanding shares, for $73.6 million during the quarter.

FY12 Outlook

We are re-confirming our FY12 sales forecast of between $2.45 and $2.60 billion, or up about 7 to 15 percent from the prior year. Our current forecast is based on the Euro at US$1.39 and 78 Yen to the US$, which, in aggregate, is slightly less favorable than our original guidance issued in August.

• Our full year operating margin is forecast to be 13.7 to 14.5 percent. Our annual stock option expense is estimated to be between $7.0 and $9.0 million with approximately 50 percent of that incurred in our second quarter.
• Our full year FY12 tax rate is anticipated to be between 27 and 30 percent.
• Our full year FY12 EPS projection has been increased to be between $3.25 and $3.50.
• Cash generated by operating activities is projected to be between $260 and $290 million in FY12. Capital spending is estimated to be approximately $100 million.

Engine Products: We expect full year sales to increase 8 to 15 percent, including the impact of foreign currency translation.

• We anticipate sales to both our On-Road and Off-Road OEM Customers will grow at a moderate rate in FY12. We will also continue to benefit from increased market share on our Customers' new Tier IV equipment platforms.
• Sales of our Aftermarket Products are expected to remain strong based on current utilization rates for both off-road equipment and on-road heavy trucks. We should also benefit from our continued expansion into the emerging economies and from the increasing number of systems installed in the field with our proprietary filtration systems such as PowerCore®.
• We forecast Aerospace and Defense Products sales to be level with the prior year as the continued slowdown in military spending is anticipated to be offset by increased commercial aerospace sales.

Industrial Products: We forecast full year sales to increase 7 to 15 percent, including the impact of foreign currency translation.

• Our Industrial Filtration Solutions' sales are projected to increase 7 to 14 percent and assume a continuing improvement in general manufacturing activity.
• We anticipate our Gas Turbine Products' sales to be up 18 to 25 percent due to the recent strengthening in the large turbine power generation market and ongoing strength in the oil and gas market segment.
• Special Applications Products' sales are forecast to decrease 1 to 7 percent as the recent flood in Thailand is expected to temporarily reduce demand for our disk drive filters.

SAFE HARBOR STATEMENT UNDER THE SECURITIES REFORM ACT OF 1995

The Company desires to take advantage of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995 (the "Act") and is making this cautionary statement in connection with such safe harbor legislation. This announcement contains forward-looking statements, including forecasts, plans, and projections relating to our business and financial performance and global economic conditions, which involve uncertainties that could materially impact results.

The Company wishes to caution investors that any forward-looking statements are subject to uncertainties and other risk factors that could cause actual results to differ materially from such statements, including but not limited to risks associated with: world economic factors and the ongoing economic uncertainty, reduced demand for hard disk drive products with the increased use of flash memory, the potential for some Customers to increase their reliance on their own filtration capabilities, currency fluctuations, commodity prices, political factors, the Company's international operations, highly competitive markets, governmental laws and regulations including the impact of various economic stimulus and financial reform measures, the implementation of our new information technology systems, potential global events resulting in market instability including financial bailouts of sovereign nations, political changes, military and terrorist activities, health outbreaks, natural disasters, and other factors included in our Annual and Quarterly Reports. We undertake no obligation to publicly update or revise any forward-looking statements.

Although free cash flow, EBITDA, net sales excluding foreign currency translation, net earnings excluding foreign currency translation, net earnings excluding restructuring charges and net earnings per share assuming dilution excluding restructuring charges are not measures of financial performance under GAAP, the Company believes they are useful in understanding its financial results. Free cash flow is a commonly used measure of a company's ability to generate cash in excess of its operating needs. EBITDA is a commonly used measure of operating earnings less non-cash expenses. Both net sales and net earnings excluding foreign currency translation provide a comparable measure for understanding the operating results of the company's foreign entities excluding the impact of foreign exchange. Both net earnings excluding restructuring charges and earnings per share excluding restructuring charges provide a comparable measure for understanding the results of the Company as compared to prior periods. A shortcoming of these financial measures is that they do not reflect the company's actual results under GAAP. Management does not intend these items to be considered in isolation or as a substitute for the related GAAP measures.
