<P STYLE="margin-top:6pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On August&nbsp;21, 2024, the transactions contemplated by the Merger Agreement were consummated, including the Merger, whereby Merger Sub
merged with and into the Issuer, with the Issuer continuing as a wholly owned subsidiary of Nordson. Pursuant to the terms of the Merger Agreement, each issued and outstanding share of Common Stock (other than shares of Common Stock (i)&nbsp;held in
the treasury of the Issuer or owned by any direct or indirect wholly owned subsidiary of the Issuer immediately prior to the Effective Time, (ii)&nbsp;owned by Merger Sub, Nordson or any direct or indirect wholly owned subsidiary of Nordson
immediately prior to the Effective Time, or (iii)&nbsp;held by a holder or beneficial holder that or who was entitled to demand and has properly demanded appraisal for such shares of Common Stock in accordance with, and that or who complied in all

terms of the Voting Agreements. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On August&nbsp;21, 2024, in connection with the Merger, the Issuer notified The Nasdaq Global Select
Market (&#147;<U>Nasdaq</U>&#148;) of the consummation of the Merger and requested that trading of the shares of Common Stock on Nasdaq be suspended prior to the opening of trading on August&nbsp;21, 2024. In addition, at the Issuer&#146;s request,
Nasdaq filed with the SEC an application on Form 25 to delist the shares of Common Stock from Nasdaq and deregister the shares of Common Stock under Section&nbsp;12(b) of the Securities and Exchange Act of 1934, as amended (the
&#147;<U>Act</U>&#148;). Trading of shares of Common Stock on Nasdaq was suspended prior to the opening of trading on August&nbsp;21, 2024. The Issuer intends to file with the SEC a Form 15 requesting that the Issuer&#146;s reporting obligations
under Section&nbsp;13 and Section&nbsp;15(d) of the Act be suspended. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">As a result of the foregoing and as of the Effective Time, to the
