Reconciliations of all non-GAAP financial measures are set forth in the attached tables, and the corresponding descriptions are contained in our report on Form 8-K to which this release is attached.

Fiscal 2011 Second Quarter Key Developments

•

Sales were $566 million, compared with $443 million in the same quarter last year. Sales increased as a result of strong organic growth of 31 percent, partially offset by a 2 percent unfavorable impact from foreign currency effects and an unfavorable impact from fewer business days.

•

Pre-tax restructuring and related charges of $5 million, or $0.05 per diluted share, were recorded in the quarter. The company realized pre-tax benefits from restructuring programs of approximately $41 million.

•

Operating income was $62 million compared with operating income of $15 million in the same quarter last year. Absent restructuring and related charges in both periods, operating income was $67 million, compared with operating income of $20 million in the prior year quarter. Adjusted operating margin reached a second quarter record of 11.8 percent. The strong margin performance was driven by higher sales, favorable capacity utilization and mix, and incremental restructuring benefits of $8 million. These benefits were partially offset by the restoration of temporary cost reductions, higher input costs and higher employment costs.

•

The effective tax rate was 21.3 percent compared to 27.6 percent for the September quarter. The sequential decrease in the rate was primarily driven by the favorable impact of the Tax Relief Act of 2010, particularly the RD&E credit extension, and the strength of our pan-European operations.

•

Reported EPS were $0.52 compared with prior year quarter reported EPS of $0.07. Adjusted EPS were $0.57 compared with prior year quarter adjusted EPS of $0.14. A reconciliation follows:

Earnings Per Diluted Share Reconciliation

Second Quarter FY 2011						Second Quarter FY 2010
Reported EPS		$	0.52			Reported EPS		$	0.07
Restructuring and related charges			0.05			Restructuring and related charges			0.07
Adjusted EPS		$	0.57			Adjusted EPS		$	0.14

•

Cash flow from operating activities was $67 million for the six months ended December 31, 2010, compared with $53 million in the prior year period. Net capital expenditures were $14 million for the six months ended December 31, 2010. The company generated year to date free operating cash flow of $54 million compared with $36 million in the same period last year.

•

Adjusted ROIC was 10.9 percent as of December 31, 2010.

Segment Developments for the Fiscal 2011 Second Quarter

•

Industrial segment sales of $369 million improved by 33 percent from $278 million in the prior year quarter, driven by organic growth of 37 percent, partially offset by unfavorable foreign currency effects of 2 percent and an unfavorable impact due to fewer business days. On an organic basis, sales increased in most served market sectors led by strong growth in general engineering and transportation sales of 49 percent and 36 percent, respectively. On a regional basis, sales increased by approximately 48 percent in Asia, 34 percent in Europe and 31 percent in the Americas.

•

Industrial segment operating income was $42 million compared with $6 million for the same quarter of the prior year. Absent restructuring and related charges recorded in both periods, Industrial operating income was $46 million compared with $9 million in the prior year quarter. The primary drivers of the increase in operating income were higher sales volume, improved capacity utilization, better product mix and incremental restructuring benefits. These benefits were partially offset by the restoration of temporary cost reductions and higher input costs. Industrial adjusted operating margin increased substantially from the prior year quarter to 12.4 percent from 3.1 percent.

•

Infrastructure segment sales of $197 million increased 19 percent from $165 million in the prior year quarter due to organic growth. The organic increase was driven by higher sales in the energy and earthworks markets of 22 percent and 17 percent, respectively. On a regional basis, organic sales increased by approximately 24 percent in Asia, 21 percent in the Americas and 12 percent in Europe.

•

Infrastructure segment operating income was $22 million, compared with $18 million in the same quarter of the prior year. Absent restructuring and related charges recorded in both periods, Infrastructure operating income was $23 million in the current quarter compared with $20 million in the prior year quarter. Operating income improved primarily due to higher sales, increased capacity utilization and incremental restructuring benefits, partially offset by higher input costs and the restoration of temporary cost reductions. Infrastructure adjusted operating margin remained relatively flat at 11.8 percent compared to the prior year quarter.

Fiscal 2011 First Half Key Developments

•

Sales were $1,095 million, compared with $852 million in the same period last year. Sales increased as a result of strong organic growth of 33 percent, partially offset by a 3 percent unfavorable impact from foreign currency effects and an unfavorable impact from fewer business days.

•

Operating income was $119 million compared with operating income of $6 million in the same period last year. Absent restructuring and related charges in both periods, operating income was $129 million, compared with operating income of $19 million in the same period of the prior year. The corresponding adjusted operating margins were 11.7 percent and 2.2 percent for six months ended December 31, 2010 and 2009, respectively.

•

Reported EPS were $0.94 compared with a loss per share of $0.05 in the prior year period. Absent restructuring and divestiture related charges, adjusted EPS for the current year were $1.04, compared with the prior year period adjusted EPS of $0.10.

Outlook

Global economic conditions and worldwide industrial production are expected to continue to improve. As such, Kennametal has increased its fiscal 2011 organic sales growth guidance to a range of 21 percent to 24 percent from its previous estimate of 19 percent to 21 percent. Foreign currency impacts are still expected to be slightly negative for fiscal 2011.

The company has also increased its EPS guidance for fiscal 2011 to the range of $2.50 to $2.65 per share from the previous range of $2.25 to $2.45 per share, excluding charges related to restructuring.

Cash flow from operations is expected to be in the range of $260 million to $280 million for fiscal 2011 as compared to the previous range of $240 million to $260 million. Capital expenditures are expected to be approximately $80 million which is unchanged from the previous guidance. The range of free operating cash flow is increased to $180 million to $200 million from $160 million to $180 million.

Dividend Declared

Kennametal also announced that its Board of Directors declared a regular quarterly cash dividend of $0.12 per share. The dividend is payable February 23, 2011 to shareowners of record as of the close of business on February 8, 2011.

Kennametal advises shareowners to note monthly order trends, for which the company makes a disclosure ten business days after the conclusion of each month. This information is available on the Investor Relations section of Kennametal’s corporate website at www.kennametal.com.

Certain statements in this release may be forward-looking in nature, or “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements are statements that do not relate strictly to historical or current facts. For example, statements about Kennametal’s outlook for earnings, sales volumes, and cash flow for fiscal year 2011 and our expectations regarding future growth and financial performance are forward-looking statements. These statements are based on current estimates that involve inherent risks and uncertainties. Should one or more of these risks or uncertainties materialize, or should the assumptions underlying the forward-looking statements prove incorrect, our actual results could vary materially from our current expectations. There are a number of factors that could cause our actual results to differ from those indicated in the forward-looking statements. They include: prolonged economic recession; restructuring and related actions (including associated costs and anticipated benefits); availability and cost of the raw materials we use to manufacture our products; our foreign operations and international markets, such as currency exchange rates, different regulatory environments, trade barriers, exchange controls, and social and political instability; changes in the regulatory environment in which we operate, including environmental, health and safety regulations; our ability to protect and defend our intellectual property; competition; our ability to retain our management and employees; demands on management resources; demand for and market acceptance of our products; integrating acquisitions and achieving the expected savings and synergies; business divestitures; implementation of environmental remediation matters; and successful completion of information systems upgrades, including our enterprise system software. Many of these risks are more fully described in Kennametal’s latest annual report on Form 10-K and its other periodic filings with the Securities and Exchange Commission. We undertake no obligation to release publicly any revisions to forward-looking statements as a result of future events or developments.

In addition to reported results under generally accepted accounting principles in the United States of America (GAAP), the following financial highlight tables include, where appropriate, a reconciliation of adjusted results including gross profit, operating expense, operating income, Industrial operating income and margin, Infrastructure operating income and margin, net income and diluted earnings per share, free operating cash flow and return on invested capital (which are non-GAAP financial measures), to the most directly comparable GAAP measures. For those adjustments that are presented ‘net of tax’, the tax effect of the adjustment can be derived by calculating the difference between the pre-tax and the post-tax adjustments presented. The tax effect on adjustments is calculated by preparing an overall tax calculation including the adjustments and then a tax calculation excluding the adjustments. The difference between these calculations results in the tax impact of the adjustments.

Management believes that investors should have available the same information that management uses to assess operating performance, determine compensation and assess the capital structure of the company. These non-GAAP measures should not be considered in isolation or as a substitute for the most comparable GAAP measures. Investors are cautioned that non-GAAP financial measures utilized by the company may not be comparable to non-GAAP financial measures used by other companies. Reconciliations of all non-GAAP financial measures are set forth in the attached tables and descriptions of certain non-GAAP financial measures are contained in our report on Form 8-K to which this release is attached.
