Altra Holdings Reports Record Sales with a 20% Year-over-Year Sales Increase

in First Quarter 2012

BRAINTREE, Mass., April 27, 2012 —Altra Holdings, Inc. (Nasdaq:AIMC), a leading global supplier of electromechanical power transmission and motion control products, today announced unaudited financial results for the first quarter ended March 31, 2012.

Financial Highlights

• First-quarter net sales increased 20% to a record $192.4 million compared with $159.8 million in the prior-year quarter. This represents 4% growth, excluding acquisitions.

• First-quarter income from operations increased 8% to $21.6 million from $20.0 million in the first quarter of 2011.

• First-quarter net income decreased 2% to $10.5 million, or $0.39 per diluted share, from $10.7 million, or $0.40 per diluted share, in the first quarter of 2011. First-quarter 2012 net income includes $0.2 million in acquisition-related costs. Excluding these costs, non-GAAP adjusted earnings per share was $0.40 per diluted share.*

• Cash and cash equivalents remains strong at $79.9 million as of March 31, 2012.

Management Comments

“We executed well on our growth strategy during the quarter and achieved top- and bottom-line financial results that exceeded our guidance,” said Carl Christenson, President and CEO. “Our 20% year-over-year revenue increase resulted in a record sales quarter. Excluding acquisitions, we grew 4%, driven primarily by strength in North America and Asia, which was partially offset by weaker than expected demand in Europe. Demand was particularly strong in our energy end market. We continue to be pleased with our Bauer acquisition, have completed integration, and have now shifted our focus to profit improvement and capitalizing on sales synergies.”

Business Outlook

“Based on what we are seeing in our markets, we expect that our second quarter results should be very similar to our performance in the first quarter, and we are maintaining our guidance for the full year,” said Christenson. “As we continue through fiscal 2012, we will execute on our organic growth strategy by developing new products that target key markets and are in direct alignment with our customers’ needs; expanding our presence in underpenetrated geographic markets; complementing organic growth with strategic, bolt-on acquisitions; and enhancing operational performance and maintaining a sharp focus on cost management to gain the most leverage out of every incremental sales dollar. We look forward to reporting record financial results for full year 2012.”

Altra is maintaining its guidance for full year 2012. The Company is forecasting sales in the range of $740 to $760 million and non-GAAP adjusted diluted EPS of $1.50 to $1.60. Altra expects its tax rate for the full year to be approximately 31% to 33%, before discrete items, capital expenditures in the range of $30 to $35 million, and depreciation and amortization in the range of $27 to $30 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 acquisition related 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). Non-GAAP free cash flow is calculated by deducting purchases of property, plant and equipment from new cash provided by operating activities.

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