Exhibit 99.1

Altra Holdings Reports Third-Quarter Financial Results

Increases Dividend 20% to $0.06 per share for the Fourth Quarter

Company Maintains Guidance for Full-Year 2012

BRAINTREE, Mass., October 25, 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 third quarter ended September 29, 2012.

Financial Highlights

Management Comments

“We performed in line with our expectations in the third quarter,” said Carl Christenson, President and CEO. “We were able to maintain our gross margin at 29.8% and a 10.5% operating margin on a year-over-year basis despite weakness in a variety of end markets and significant foreign exchange headwinds. As a result of continued sluggish demand in Europe, we have begun to take actions in that geography to improve profitability in the coming quarters. These actions, which we expect to accelerate during the next few quarters, include reducing headcount, limiting discretionary spending, moving certain product line manufacturing to low-cost countries, and raising pricing in certain end markets. We continue to see sales growth in North America and Asia.”

Business Outlook

“Looking at the remainder of 2012, we are on track to meet our top and bottom line guidance for the full year and we are optimistic about further success in 2013,” said Christenson. “Given that our 8 1/8 senior secured notes become callable December 1, 2012, and the current strength in the credit markets, we currently are evaluating refinancing options”, continued Christenson.

The Company currently is forecasting sales in the range of $720 to $735 million and non-GAAP adjusted diluted EPS of $1.35 to $1.45 for 2012. Altra now expects its tax rate for the full year to be approximately 32% before discrete items. The Company continues to expect capital expenditures in the range of $30 to $35 million, and depreciation and amortization in the range of $25 to $28 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, amortization of inventory fair value adjustment, premium paid on the redemption of debt 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.
