SAN FRANCISCO--(BUSINESS WIRE)-- Proof Mark, Inc. (PMI), a longtime Salesforce (NYSE: CRM ) partner and shareholder, today announced that the company has issued an important open letter to Salesforce chairman and CEO Marc Benioff. The letter addresses a range of critical operational and fiduciary issues which have been raised by PMI in four consecutive Red Flag Notices issued under the Delaware Chancery Court ruling in the re McDonald's Corp. Stockholder Derivative Litigation and related cases. As both a Salesforce shareholder and long-standing ISV partner, PMI brings a dual fiduciary and ecosystem perspective to these concerns. To date, Salesforce's board has not responded to any of the Red Flag notices, a silence exceeding 30 days and raising serious fiduciary concerns for shareholders, regulators, and ecosystem stakeholders, especially those with a special interest in the governance and performance of the company.
