For the full year 2025, we expect to return at least 70% of free cash flow to shareholders through dividends and share repurchases. We plan to take a dynamic approach to capital allocation as we invest in growth opportunities that position IDEX for continued value creation and success,” said Eric D. Ashleman, IDEX Corporation President and Chief Executive Officer. “In the near-term, we intend to deploy free cash flow towards expanding our capabilities through bolt-on acquisitions and returning capital to shareholders – all while continuing to deliver on our strategy as a growth compounder. We continue to apply our 8020 operating model across IDEX to help ensure we are directing resources toward the highest-return opportunities. Of note, in 2025, we have accelerated our buyback activity, repurchasing over $100 million in the first half of 2025 alone,” concluded Mr. Ashleman. The Board also approved a regular quarterly cash dividend of $0.71 per common share. This dividend will be paid on October 24, 2025 to shareholders of record as of October 10, 2025. This dividend represents the company’s 124th consecutive regular quarterly cash dividend payment. The newly announced increase in the share repurchase authorization does not obligate the Company to repurchase any dollar amount or number of shares of common stock. The share authorization may be suspended or discontinued at any time.
