Supplement to Proxy Statement for 2017 Annual Meeting of Stockholders
IPG Photonics Corporation
50 Old Webster Road
Oxford, MA 01540


This Amendment No. 1 ("Amendment") modifies the definitive proxy statement on Schedule 14A filed by IPG Photonics Corporation (the "Company") with the Securities and Exchange Commission on April 5, 2017 (the "Proxy Statement").

The sole purpose of this Amendment is to update the common stock ownership percentage in the beneficial ownership table for Timothy P.V. Mammen to "*". This symbol "*" means that Mr. Mammen beneficially owns less than 1% of the outstanding stock.

The table appearing in the Proxy Statement section “Common Stock Ownership” providing information about the beneficial ownership of our common stock as of April 3, 2017 is amended and restated in its entirety and replaced with the following table:
