In a stockholder appraisal action brought by a large shareholder of a billion-dollar financial services company, a Brattle principal advised the acquiring company to evaluate the petitioner’s appraisal demand. In the trial in the Delaware Court of Chancery, he supported a testifying expert, who effectively argued that the final merger consideration was fair, basing his testimony on contemporaneous market evidence and a discounted cash flow valuation analysis. The Court agreed, and rejected the petitioners’ claim.
