directors and officers of IPG Photonics Corporation (the &#8220;Company&#8221;) adopted
pre-arranged trading plans (each, a &#8220;Plan&#8221;) designed to comply with
Rule&#160;10b5-1 under the Securities Exchange Act of 1934, as amended, and the
Company&#8217;s policies regarding stock transactions. Under Rule&#160;10b5-1,
directors, officers and other persons who are not in possession of material
non-public information may adopt a plan or contract for pre-arranged sales of
Company securities under specified conditions and at specified times. Using
these Plans, insiders can gradually diversify their investment portfolios,
spread stock trades out over an extended period of time to reduce market impact
and avoid concerns about transactions occurring at a time when they might
possess inside information.</font></div>
