(exechange) — Boise, Idaho, February 5, 2018 — Ernie Maddock, finance chief of Micron, leaves the position. It is a change at short notice. As announced by Micron Technology, Inc. in a news release and in a regulatory filing published on Monday, February 5, 2018, Ernest E. (Ernie) Maddock leaves his post as chief financial officer at the maker of semiconductor devices after less than three years in the position, effective February 19, 2018.

No company wants a CFO to flame out in the first years.

Among the 3,000 largest publicly held companies incorporated in the U.S. based on market capitalization, the average tenure of the CFOs who departed over the past 12 months was 6.1 years, according to data compiled by exechange. Only 35 percent of the CFOs who departed over the past 12 months left the position within three years.

Maddock’s move comes nine months after Sanjay Mehrotra took over as CEO of Micron Technology, Inc.

Maddock leaves the company effective June 8, 2018.

Maddock’s duties will be taken over by Dave Zinsner, most recently president and chief operating officer at Affirmed Networks, Inc.

The fact that Maddock’s successor is brought in from outside suggests that the board may seek to stimulate change with fresh ideas and new initiatives.

No reason given

In the announcement, Micron did not explicitly explain the reason for Maddock’s imminent move, leaving room for speculation.

Precise information about Maddock’s future plans was not immediately available.


Micron said: “Zinsner succeeds Ernie Maddock, who is retiring from Micron but will remain with the company as an adviser through early June to ensure a smooth transition.”

Micron further said: “On February 1, 2018, Ernest E. Maddock announced his intention to retire from Micron Technology, Inc. … on June 8, 2018. Mr. Maddock will serve as the Company’s Senior Vice President and Chief Financial Officer until February 19, 2018 and, to provide for an orderly transition of duties, as an advisor to the Company from February 19, 2018 to June 8, 2018.”
