Mo. Rev. Stat. § 362.750
Within twenty days after the filing of the appraisal, exceptions in writing may be filed thereto by any party interested. If exceptions are so filed the court shall review the appraisal and may order, on good cause shown, a new appraisal by other appraisers, or the court may hear evidence touching matters in controversy and take an accounting to ascertain and determine the value of the shares and may make the order that justice, equity and right require. If no exceptions are filed to the report of the appraisers, the court shall enter final judgment approving the report. If any of the orders herein provided for are made in vacation, the vacation orders shall be considered and confirmed by the court. In its judgment the court shall ascertain and determine the value of the shares of stock of the merging bank, banks, trust company or trust companies, of the consolidating banks or trust companies, or of the bank or trust company in a reverse stock split at the time of the merger, consolidation or reverse stock split. When the receiving bank or trust company under the merger, the consolidated bank or trust company under the consolidation or the bank or trust company in a reverse stock split has paid the value of the stock as determined by the court, the stock shall be surrendered and the stockholder shall cease to have any interest in the stock or in the corporate property of the corporation and the corporation shall not hold such stock as treasury stock.
