Teledyne Vice Chairman Jason VanWees to retire; Mary Grace DeForest named VP IR and M&A

Teledyne Technologies is resetting a long-running leadership role in capital allocation and investor outreach. In a Monday 8-K and press release, the company said Vice Chairman Jason VanWees will retire from his current position effective February 1, 2027, when he will be age 55.

VanWees joined Teledyne before its 1999 spin-off and was named vice chairman in 2021, the release said. Teledyne credited him with leading the identification and acquisition of 75 complementary businesses for cumulative consideration of $12.8 billion. Shares closed Monday at $610.83, down about 0.5% on the day and up roughly 18% year to date.

Mary Grace DeForest, senior vice president and general manager of Teledyne Microwave, has been appointed corporate vice president of investor relations and mergers and acquisitions, effective November 1, 2026. The release said she currently has P&L responsibility for a group of businesses with 880 employees and about $320 million of annual revenue, and that she joined Teledyne in 2011.

Executive Chairman Robert Mehrabian said VanWees had been an "equal partner" overseeing growth strategy and capital allocation and had led discussions with the investment community for decades. Mehrabian also said VanWees's retirement and DeForest's appointment overlap "to ensure continuity in this important role."
