Invitation to 2025 Annual Meeting of Stockholders
Dear Fellow Stockholder:We are pleased to invite you to join us, our Board of Directors, executive officers, associates and other stockholders at Atmus' 2025 Annual Meeting of Stockholders. The attached notice of our 2025 Annual Meeting of Stockholders and Proxy Statement, which we are providing to stockholders beginning on April 2, 2025, contain details of the stockholder business to be conducted at the meeting.
2024 – An Unforgettable Year at Atmus 2024 was an unforgettable year at Atmus, in which the completion of a successful share exchange marked our full independence as a company from Cummins. We established a reputation for disciplined execution and continued to deliver on our growth strategy.
What did we accomplish in 2024?
Delivered on our growth strategy and achieved strong financial results
•We grew revenue from $1,628M to $1,670M, an increase of 2.5% from 2023 despite challenging market conditions.•We achieved $330M in adjusted EBITDA*, resulting in net debt to adjusted EBITDA of 1.2X positioning us well to execute on our growth strategy both organically and inorganically. •We created stockholder value, completing the share exchange with Cummins divesting the remaining 80.5% of its shareholding. Throughout 2024, Atmus Cumulative Total Shareholder Return outperformed the S&P 500 and S&P 500 Industrial benchmarks.
Continued delivering on our supply chain transformation
•We established Atmus controlled distribution facilities for approximately 95% of our volume, improving on-shelf availability for our customers and driving market share gains.•We delivered cost savings in our supply chain ahead of our plan, supporting improved profitability; we delivered 110 basis points improvement in gross margin as a percent of net sales in 2024.
Invested in our Atmus culture, prioritizing initiatives that promote Atmus’ core values: build trust, be inclusive, have courage and show caring
As we continue to evolve as an independent company, it is important that our governing principles grow with us. Stockholder feedback continues to inform how we approach Atmus’ governance practices. In line with this, proposals for enhancements to our governance provisions will be presented during our meeting.
As we approach our second Annual Meeting of Stockholders, we thank you in advance for voting and for your continued support of Atmus.

Chief Executive Officer	Chair of the Board
