How much of the $150M authorization has been used?

Atmus has repurchased approximately $101 million under the authorization through Q2 2026 ($150M authorized less $49M remaining). The $13 million Q2 repurchase was part of this cumulative execution since the program's July 2024 authorization.

What mechanism does Atmus use for repurchases?

The filing indicates these are open-market repurchases under Rule 10b-18, which is the standard safe harbor mechanism allowing companies to repurchase shares during trading windows without violating insider trading rules.

How does this buyback fit into Atmus's capital allocation strategy?

The $13M Q2 repurchase represents a conservative use of free cash flow alongside a quarterly dividend of $0.055 per share. With adjusted free cash flow of $67M in Q2, the company is balancing buybacks with debt reduction (long-term debt increased to fund the Koch Filter acquisition) and organic growth investments.

What is the share count impact?

While shares repurchased are not disclosed for Q2, the diluted share count declined to 82.0 million from 83.0 million year-over-year, reflecting cumulative buyback activity. The treasury stock balance increased to 2.3 million shares at June 30, 2026, from 2.0 million at year-end 2025.

Is Atmus still actively using the authorization?

Yes. With $49 million remaining and the company generating strong free cash flow ($67M in Q2, $115.9M for the first half of 2026), Atmus is expected to continue opportunistic repurchases under the program.

When was this authorization approved?

The $150 million program was authorized by the Board of Directors in July 2024, approximately one year before the Q2 2026 reporting period.

What this means

Atmus's Q2 buyback of $13 million represents approximately 1.6% of the original $150 million program authorization. With $49 million still available, the company has deployed roughly 67% of the authorized capital. This execution rate suggests a measured approach to share repurchases, consistent with capital-disciplined management. The buyback occurs in the context of recent debt increase (long-term debt rose to $992 million from $540 million, reflecting the Koch Filter acquisition financing) and strong free cash flow generation, indicating the company is balancing shareholder returns with debt paydown and integration priorities.
