Third-quarter Financial Highlights

•

Net sales increased 38% to $177.9 million compared with $128.9 million in the prior-year quarter. This represents 14% growth, excluding the Bauer acquisition.

•

Income from operations increased 37% to $18.7 million from $13.6 million in the third quarter of 2010.

•

Net income increased 84% to $12.1 million, or $0.46 per diluted share, from $6.6 million, or $0.25 per diluted share, in the third quarter of 2010. Third-quarter 2011 net income includes $1.2 million in acquisition-related costs and costs related to the repurchase of $8.2 million of 8 1/8 % Senior Secured Notes, offset by $3.6 million in one-time discrete tax benefits. Third-quarter of 2010 net income included $0.5 million in restructuring charges. Excluding these items in both periods, non-GAAP adjusted net income increased 35% to $9.3 million, or $0.35 per share diluted share.*

•

Cash and cash equivalents were $90.3 million at October 1, 2011 compared with $72.7 million at December 31, 2010.

•

Altra repurchased $8.2 million of 8 1/8% Senior Secured Notes during the third quarter. The Company repurchased an additional $3.7 million of 8 1/8 % Senior Secured Notes thus far in the current fourth quarter.

Management Comments

“Altra reported excellent top- and bottom-line growth in the third quarter of 2011,” said Carl Christenson, President and CEO. “Our impressive 14% sales increase, excluding acquisitions, was driven by very robust growth in energy and mining and solid demand in nearly all other end markets. In addition, our Bauer acquisition is performing well, reporting sales and operating results in line with the high side of our expectations. We also leveraged our strong top-line performance into a 37% year-over-year increase in income from operations and a 35% increase in non-GAAP adjusted net income.”

Business Outlook

“We are encouraged by the positive demand environment that we see across nearly all of our end markets,” said Christenson. “In addition, Bauer’s performance thus far gives us greater optimism that we can accelerate its sales and profitability growth in 2012. Today we are thrilled to announce the simultaneous launch of the Bauer product range through the Altra North American sales team and a new innovative gear product line partially based on Bauer technology. We continue to have a strong balance sheet and ample liquidity to pursue strategic acquisitions in the quarters ahead. In addition, we are executing on our aggressive organic growth strategy that includes targeting new and existing markets through new product development, increasing our presence in key underpenetrated geographic regions, and entering high growth markets.”

As a result of the Company’s excellent performance in the first nine months of 2011, and the positive demand environment, the company is narrowing its full year guidance to the high end of the previously disclosed guidance range. Altra now is forecasting sales in the range of $670 to $680 million and non-GAAP adjusted EPS in the range of $1.43 to $1.53. The Company expects its tax rate for the full year to be in the range of 31.0% to 33.0%, before discrete items. Altra anticipates capital expenditures in the range of $20 to $22 million and depreciation and amortization is expected to be in the range of $24 to $25 million.

*Discussion of Non-GAAP Financial Measures

As used in this release and the accompanying slides posted on the company’s website, non-GAAP adjusted diluted earnings per share, non-GAAP adjusted income from operations and non-GAAP adjusted net income are each calculated using either net income or income from operations that excludes premiums, discounts and costs associated with the extinguishment of debt, acquisition related costs, restructuring costs, discrete tax items and other income or charges that management does not consider to be directly related to the company’s core operating performance. Non-GAAP adjusted diluted earnings per share is calculated by dividing non-GAAP adjusted net income by GAAP weighted average shares outstanding (diluted).

Altra believes that the presentation of non-GAAP adjusted net income, non-GAAP adjusted income from operations and non-GAAP adjusted diluted earnings per share provides important supplemental information to management and investors regarding financial and business trends relating to the company’s financial condition and results of operations.

All statements, other than statements of historical fact included in this release are forward-looking statements, as that term is defined in the Private Securities Litigation Reform Act of 1995. These statements include, but are not limited to, any statement that may predict, forecast, indicate or imply future results, performance, achievements or events. Forward-looking statements can generally be identified by phrases such as “believes,” “expects,” “potential,” “continues,” “may,” “should,” “seeks,” “predicts,” “anticipates,” “intends,” “projects,” “estimates,” “plans,” “could,” “designed”, “should be,” and other similar expressions that denote expectations of future or conditional events rather than statements of fact. Forward-looking statements also may relate to strategies, plans and objectives for, and potential results of, future operations, financial results, financial condition, business prospects, growth strategy and liquidity, and are based upon financial data, market assumptions and management’s current business plans and beliefs or current estimates of future results or trends available only as of the time the statements are made, which may become out of date or incomplete. Forward-looking statements are inherently uncertain, and investors must recognize that events could differ significantly from our expectations. These statements include, but may not be limited to, those comments regarding the Company’s plan to execute aggressively its growth strategy during the remainder of 2011, its strategy to capitalize on growth opportunities in new and existing markets, increase its presence in key underpenetrated geographic regions, enter new high-growth markets and pursue strategic acquisitions, the Company’s positioning in its end markets and its opportunities for long-term growth, the Company’s expectations regarding the integration of Bauer and the Company’s expectations for Bauer’s sales and profitability, the positive demand signs in Altra’s end markets, the Company’s optimism regarding sales and profitability growth in 2012, the seasonality of the business, and the Company’s guidance for 2011 for sales, EPS, capital expenditures, depreciation and amortization, and tax rate.

In addition to the risks and uncertainties noted in this release, there are certain factors that could cause actual results to differ materially from those anticipated by some of the statements made. These include: (1) competitive pressures, (2) changes in economic conditions in the United States and abroad and the cyclical nature of our markets, (3) loss of distributors, (4) the ability to develop new products and respond to customer needs, (5) risks associated with international operations, including currency risks, (6) accuracy of estimated forecasts of OEM customers and the impact of the current global economic environment on our customers, (7) risks associated with a disruption to our supply chain, (8) fluctuations in the costs of raw materials used in our products, (9) product liability claims, (10) work stoppages and other labor issues, (11) changes in employment, environmental, tax and other laws and changes in the enforcement of laws, (12) loss of key management and other personnel, (13) changes in pension and retirement liabilities, (14) risks associated with compliance with environmental laws, (15) the ability to successfully execute, manage and integrate key acquisitions and mergers, (16) failure to obtain or protect intellectual property rights, (17) risks associated with impairment of goodwill or intangibles assets, (18) failure of operating equipment or information technology infrastructure, (19) risks associated with our debt leverage and operating covenants under our debt instruments, (20) risks associated with restrictions contained in our Senior Secured Notes and Convertible Notes, (21) risks associated with compliance with tax laws, (22) risks associated with the global recession and volatility and disruption in the global financial markets, (23) risks associated with implementation of our new ERP system, (24) risks associated with the Bauer acquisition and integration, (25) risks associated with the Company’s planned investment in a new manufacturing facility in China, and (26) other risks, uncertainties and other factors described in the Company’s quarterly reports on Form 10-Q and annual reports on Form 10-K and in the Company’s other filings with the U.S. Securities and Exchange Commission (SEC) or in materials incorporated therein by reference.
