Dear Fellow Altra Employees:

Today we announced that Altra Industrial Motion Corp. is creating a focused global leader in the power transmission and motion control industry. We are combining with four operating companies from Fortive’s Automation and Specialty platform (Fortive A&S) in an approximately $3.0 billion cash and stock transaction. We believe this will result in compelling growth and value creation opportunities for you and the rest of our stakeholders. Together, we expect to have sales of approximately $1.8 billion and 52 manufacturing facilities, over 25 engineering/service centers and approximately 9,300 employees worldwide. A copy of the press release announcing this transaction is attached.

As you may know, Fortive A&S is a leader in motion control solutions. Some of you may already be familiar with its market leading brands, including Kollmorgen, Thomson, Portescap and Jacobs Vehicle Systems. Fortive A&S’s engineered servo, direct drive and specialty miniature motor technology, along with precision linear automation products and solutions, are highly complementary to our leading power transmission line-up and strong mechanical and electronic capabilities.

Importantly, both companies have cultures focused on strong operating performance and continuous improvement, with reputations for deep customer engagement. With our similar philosophies and global presence, we expect to advance Altra’s capabilities across the technological spectrum and support entry into higher-growth, higher-margin markets, such as medical, as well as new segments of material handling and robotics.

In short, this announcement is a transformational step for Altra. We could not be more excited about this combination and the potential opportunities it will bring for our business and our employees.

Next Steps: Business as Usual

Even though we are making this announcement today, it will be several months before the transaction is completed. A portion of the transaction is structured in a form called a Reverse Morris Trust, under which Fortive will go through a process to separate the Fortive A&S business prior to combining it with Altra. As part of this process, we will need to obtain certain regulatory approvals, tax authority rulings and the approval of Altra shareholders. We expect to close the transaction by end of the year.

Until that time, Altra and Fortive A&S will continue to operate as separate, independent businesses. That means that it is business as usual for all of us. We will rely on you, as we always have, to continue striving for Operational Excellence and providing our customers with the same outstanding service and innovative products and solutions they have come to expect from us.

Bringing these companies together will require a thoughtful integration plan, a process we have executed well in the past. To help facilitate this effort, we will shortly begin pulling together a transition team, which will be made up of employees of both companies. Over the next days and weeks, we will be communicating more about that team as it moves into high gear to develop the integration plan.

While there is still a lot that needs to be determined, what I can tell you is that following the completion of the transaction, the combined company will be headquartered in Braintree, Massachusetts. I will continue to lead as Chairman and CEO and Christian Storch will remain Chief Financial Officer. Our senior management team will be expanded to include both Altra and Fortive A&S employees. In addition, as I noted earlier, our businesses are highly complementary and as a result, we do not anticipate any impact from the integration on the vast majority of Altra employees, including our design, product and functional teams.


Attached is an FAQ list to help answer some of the questions you may have. We are committed to keeping you informed during each step of this process. I will provide more color as I travel to some of our facilities in the coming months. Please remember that at times like this it is critically important to understand and abide by the requirements of Altra’s Insider Trading and Publicity Policy. Please forward all inquiries from members of the media or investors to Christian Storch, Craig Schuele or Glenn Deegan who will respond on the Company’s behalf.

It is your innovative talent and contributions that have enabled our progress over the years. Looking ahead, employees will continue to be the ultimate driver of the combined company’s success. I hope you share my enthusiasm for this next chapter in our company’s history.

Sincerely,

Carl Christenson

Chairman and Chief Executive Officer
