    <remarks>On May 15, 2026,  Digimarc Parent, Inc.  (which subsequently changed its name to Digimarc Corporation) (&quot;New Digimarc&quot;)  became the successor of Digimarc Corporation (which became a wholly-owned subsidiary of New Digimarc and was converted to an Oregon limited liability company) (&quot;Old Digimarc&quot;) pursuant to an agreement and plan of reorganization, including an agreement and plan of merger attached thereto. The merger and reorganization resulted in New Digimarc's becoming a parent holding company of Old Digimarc,  but did not alter the proportionate interests of security holders.</remarks>
