Incentive Plan, as Amended and Restated (the &#147;2007 Plan&#148;), on <A HREF="http://www.sec.gov/Archives/edgar/data/851205/000095013508002593/b69636ccsv8.htm">April&nbsp;18, 2008</A> (File

(collectively, the &#147;Prior Registration Statements&#148;). On each of September&nbsp;16, 2013 and December&nbsp;1, 2017, the Company effected a <FONT STYLE="white-space:nowrap"><FONT STYLE="white-space:nowrap">two-for-one</FONT></FONT> stock
split of its Common Stock in the form of a stock dividend, which resulted in a total of 13,200,000 shares of Common Stock authorized for issuance under the 2007 Plan. Pursuant to Rule 416(a) promulgated under the Securities Act of 1933, as amended
(the &#147;Securities Act&#148;), the Prior Registration Statements were deemed to cover the additional shares of Common Stock issuable under the 2007 Plan as a result of such stock splits. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">On May&nbsp;3, 2023, shareholders of the Company approved the Cognex Corporation 2023 Stock Option and Incentive Plan (the &#147;2023
Plan&#148;). Outstanding awards granted under the 2007 Plan will continue to be governed by the terms of the 2007 Plan; however, in connection with the approval of the 2023 Plan, no further awards will be made under the 2007 Plan. As of May&nbsp;3,
2023, there were 1,468,265 shares of Common Stock that were authorized to be awarded by the Company under the 2007 Plan but that, as of such date, were not issued or subject to outstanding awards granted under the 2007 Plan.&nbsp;Accordingly, as a
result of the approval of the 2023 Plan, these 1,468,265 shares of Common Stock are no longer available for new awards under the 2007 Plan and are deregistered hereby. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Under the terms of the 2023 Plan, the Company may issue up to 4,176,633 shares of Common Stock subject to awards granted under the 2007 Plan
that were outstanding as of May&nbsp;3, 2023 and that may become eligible for issuance under the 2023 Plan if such awards are forfeited, cancelled or otherwise terminated (other than by exercise) (the &#147;Carryover Shares&#148;). The Company has
filed this Post-Effective Amendment to add the 2023 Plan to the Prior Registration Statements, without registering any additional securities thereunder, as the Carryover Shares may now be issuable pursuant to the 2023 Plan. </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; text-indent:4%; font-size:10pt; font-family:Times New Roman">Contemporaneously with the filing of this Post-Effective Amendment, the Company is filing a Registration Statement on <FONT
