"Since the beginning of Teledyne Technologies, Jason and I have been equal partners overseeing Teledyne's growth strategy and capital allocation," said Robert Mehrabian, Executive Chairman. "At the same time, given his extensive knowledge of our businesses and markets, Jason has led Teledyne's discussions with the investment community for decades. I express personally, and on behalf of everyone at Teledyne, that Jason will be sorely missed."

Mary Grace DeForest joined Teledyne in 2011 as a Manufacturing Engineer and has assumed positions of increased responsibility at both the Corporate office and Teledyne businesses, including Teledyne Marine, Digital Imaging and Defense Electronics.

Jason's retirement and Mary Grace's appointment overlap to ensure continuity in this important role at Teledyne," said Robert Mehrabian, Executive Chairman.
