Didier Hirsch, Robert McMahon, Karleen Oberton

Agilent Technologies said its senior VP and CFO Didier Hirsch will retire, effective Oct 31. The company has appointed Robert McMahon, currently CFO of Hologic, as his successor. McMahon will join Agilent on Aug. 3 as senior VP and will become CFO on Sept. 1 when Hirsch steps down from that post. Hirsch will continue as an active member of the executive staff until his retirement date at the end of the fiscal year and will work with McMahon to ensure a smooth transition.

Hirsch has served as Agilent's CFO since 2010. Before that, he had oversight of the corporate controllership and tax functions. He joined Agilent in 1999 as VP of treasury and investor relations. He also held various international finance positions at HP from 1989 until joining Agilent.
McMahon has served as Hologic's CFO since 2014. Prior to that, he spent 20 years with Johnson & Johnson, most recently as worldwide VP of finance and business development for Ortho Clinical Diagnostics. He also held a variety of financial leadership positions within Johnson & Johnson after joining the company in 1993.

Separately, Hologic said it would promote its current Chief Accounting Officer Karleen Oberton to replace McMahon as CFO. She joined Hologic in 2006 as corporate controller and was promoted to her current position in 2015. Prior to that, Oberton served as senior corporate controller for Immunogen, and as a senior audit manager for both Ernst Young and Arthur Andersen.
