ALTRA HOLDINGS ANNOUNCES RESULTS FOR
YEAR END 2006 AND THE FOURTH QUARTER 2006

QUINCY, MA — February 27, 2007

Altra Holdings, Inc. (NASDAQ: AIMC), a leading global supplier of clutch brakes, couplings, gearing and power transmission components, announced that for the year ended December 31, 2006 net income was $8.9 million compared to $2.5 million in 2005, an increase of 257.1%. Fully diluted earnings per share for 2006 was $0.46. Net sales for 2006 were $462.3 million, compared to $363.5 million for 2005, an increase of 27.2%. Gross profit as a percentage of net sales for 2006 increased to 27.1% from 25.2% in 2005. Operating income for 2006 was $41.1 million compared to $25.4 million in 2005, an increase of 62.0%. For 2006, our Hay Hall acquisition and new linear business increased net revenues by $68.8 million. Revenue performance was driven by strong distribution sales for the aftermarket and the strength of several key markets including energy, primary metals, and mining.

For the fourth quarter ended December 31, 2006 the Company recorded a net loss of $(1.8) million compared to net income of $1.3 million for the fourth quarter of 2005. Fully diluted loss per share for the fourth quarter of 2006 was $(0.46). Fourth quarter 2006 net sales were $114.8 million, compared to $90.0 million in the fourth quarter of 2005, an increase of 27.6%. Gross profit as a percentage of net sales for the fourth quarter of 2006 was 26.9% compared to 27.7% in the fourth quarter of last year. Fourth quarter 2006 operating income was $3.9 million compared to $8.3 million in the fourth quarter of 2005, a decrease of 53.3%. Excluding expenses related to the Hay Hall acquisition, the IPO executed on December 14, 2006, the restricted employee stock grants made in August 2006, and a fee associated with the termination of an advisory services agreement with Altra’s former private equity sponsor, fourth quarter 2006 operating income was $9.4 million, a 13.9% improvement over fourth quarter 2005.

Michael L. Hurt, Chairman and CEO said “By any measure our 2006 financial performance was outstanding; the 27.2% increase in revenues was the result of good execution by our management team in integrating the Hay Hall and Bear Linear acquisitions while simultaneously achieving more than 8% organic growth. Using our Altra Business System (ABS) and Low Cost Country sourcing office we improved gross profit by 190 basis points. Driven primarily by revenue growth and operational improvement, we more than tripled our full year net income to $8.9 million. This 2006 financial performance combined with our recent IPO gives Altra additional financial flexibility to grow both organically and through acquisitions. Also, we are excited about our proposed acquisition of TB Wood’s which is a perfect fit with Altra’s core business.”
