All Employee Letter

To: All Employees

From: Mark Skonieczny

Date: January 8, 2026

Subject: New Year Update

Dear Team,

I hope everyone enjoyed the holiday season and spent time with family and friends. Echoing what I shared during our year-end earnings announcement, I’m grateful for your work and commitment over the past year – your dedication was the bedrock of a successful 2025. As we look ahead, I want to share some important updates and key milestones for our proposed merger with Terex Corporation.

As I shared when we first announced this transaction, bringing our companies together will strengthen our foundation for long-term success, supported by a complementary portfolio of specialty equipment businesses and a strong U.S. manufacturing base. Over the last few months, we have worked closely with Terex towards closing the transaction. On January 28, 2026, REV and Terex will each host Special Meetings of Stockholders. During these meetings, each company’s stockholders will have the opportunity to vote on the proposed merger transaction. We expect the transaction to close shortly after these meetings, assuming both companies’ stockholders approve the deal. If you own shares in REV, you will have the opportunity to participate in the vote. We encourage all stockholders to cast their vote as promptly as possible. Further information about the Special Meetings and the proposed merger, including instructions on how to vote, can be found in our definitive joint proxy statement here, and at our merger website here.

While the leadership structure of the combined company is still being finalized, we know that it will reflect a mix of leaders from both organizations, ensuring that the REV team maintains a strong and influential voice in the new company. As we previously announced, upon closing, Simon Meester, President and CEO of Terex, will be the CEO of the combined company. Simon will be supported by talented executives from both companies who will lead across the combined organization’s core segments – Environmental Solutions, Materials Processing, Aerial Work Platforms and Specialty Vehicles (which includes our Fire, Emergency, Commercial and Recreation brands). The Fire and Emergency and Commercial leadership updates and organizational alignments that were announced last week to strengthen operational focus and improve commercial execution will be maintained under the combined company.

While the corporate leadership structure will look different, the strength of our U.S. manufacturing footprint and each brand are critical components of the rationale for bringing these businesses together, and little is expected to change for both as a result. The culture of the combined organization will be shaped by the strengths of both companies. As we bring together our successful businesses, there will be meaningful opportunities to learn from one another. As part of the combined company, you will benefit from being part of an organization with greater scale and capabilities, offering enhanced access to tools and support systems that empower greater innovation, along with expanded career opportunities.

Integration planning has been another key focus over the past months as we consider the combined company’s organizational structure. The integration planning team includes members from both REV and Terex, reinforcing a collaborative and open-minded approach to integration. Terex has been clear that this will not be a one-way integration, and that many of REV’s processes, ways of working, and cultural strengths will add real value to the combined company going forward. Further details on the integration will be shared following a successful close.

Looking ahead, our plans and priorities remain the same. Until close, REV Group and Terex will continue to operate as two separate companies. For now, everything remains business as usual, and it’s important that we remain focused on delivering great work and innovation for our customers.

This will be a significant year for REV Group, and it would not be possible without your hard work. Thank you again for your efforts last year and for the care you bring every day in delivering quality vehicles to our customers.

Sincerely,

Mark

Mark Skonieczny

President and CEO

REV Group
