Increase in the Size of the Board of Directors
​
On February 1, 2022, the Board of Directors (the "Board") of Advanced Energy Industries, Inc. (the "Company") increased the size of the Board from ten (10) to eleven (11) directors.
​
Election of Mr. David Reed to the Board of Directors
​
On February 1, 2022, the Board of the Company elected Mr. David Reed to serve as a member of the Board effective immediately.  Mr. Reed will stand for re-election at the 2022 Annual Meeting of Stockholders.
The Board appointed Mr. Reed to the Compensation Committee of the Board.

David Reed is 63 years old and recently served for six years as executive vice president global operations of NXP Semiconductors N.V.
In this role, Mr. Reed was responsible for NXP's internal and external manufacturing operations, supply chain, information technology, total quality and procurement.
Mr. Reed joined NXP as part of the merger with Freescale Semiconductor, where he had served as senior vice president manufacturing operations. Previously, Mr. Reed was vice president and general manager at GLOBALFOUNDRIES. Mr. Reed began his career at Texas Instruments in 1984, where he served for 26 years in a variety of leadership roles throughout the world.

​
Mr. Reed will be entitled to receive compensation for his service on the Board in accordance with the Company's standard compensatory arrangement for non-employee directors. In addition, in connection with his election to the Board and given his short initial director term, Mr. Reed was granted restricted common stock units in the Company with a value of approximately $50,000 representing roughly 3/12
