SUBJECT: Regal PTS to combine with Rexnord’s PMC segment

Dear Valued Supplier,

Today is a very exciting day for Regal. We announced an agreement to combine Regal’s Power Transmission Solutions business with Rexnord’s Process & Motion Control (PMC) segment to create a global leader in industrial power transmission and motion control solutions. The press release we issued can be viewed here.

As you may know, PMC is a leading global provider of specialized, highly-engineered power transmission components and solutions, with a strong portfolio of IoT-enabled offerings for OEM and retrofit applications. Together, we will combine the respective strengths of both companies to create a world-class power transmission business with enhanced growth opportunities.

One of the most important ways we will continue to deliver exceptional customer experience is through our strong vendor and partner relationships. Our goal is to maintain and reinforce our key supplier relationships.

What’s Next

We’re excited about this combination of high quality businesses, but today’s announcement is just the first step in the process. The transaction is expected to close in the fourth quarter of 2021, subject to the receipt of shareholder and regulatory approvals, and other closing conditions.

Once the transaction closes, the combined mechanical power transmission business will be renamed, “Rexnord, a Regal Company.”

Until closing, Regal and PMC remain separate companies and will continue to operate as we do today. It is business as usual and nothing will change about the way we work with you. We continue to be focused on working alongside our valued partners to deliver the critical products, services, and technologies on which our customers depend.

We will keep you updated throughout the process as appropriate. As always, if you have any questions, please don’t hesitate to reach out.

Thank you for your continued partnership.

Best regards,

Jerry Morton

President – Regal Power Transmission Solutions
