        <footnote id="F1">Pursuant to the Agreement and Plan of Merger, dated March 3, 2026, by and among the Issuer, Royal Cup, Inc. (&quot;Parent&quot;) and BP I Brew Merger Sub Inc. (&quot;Merger Sub&quot;), Merger Sub merged with and into the Issuer, with the Issuer surviving as a wholly owned subsidiary of Parent (the &quot;Merger&quot;). At the effective time of the Merger (the &quot;Effective Time&quot;), upon the terms and subject to the conditions set forth in the Merger Agreement, each share of the Issuer's common stock, par value $1.00 per share (&quot;Common Stock&quot;), that was issued and outstanding immediately prior to the Effective Time was automatically cancelled and converted into the right to receive $1.29 per share of Common Stock in cash, without interest. The disposition of the securities by the Reporting Person in the Merger was approved by the Company's board of directors in the manner contemplated by Rule 16b-3 under the Securities Exchange Act of 1934, as amended.</footnote>
