Robert Riegel filed a lawsuit in the U.S. District Court for the Western District of Texas claiming the grocer's July 7 proxy statement was "misleading," "failed to disclose information important to stakeholders" and "failed to disclose how the company calculated certain valuations," Progressive Grocer reported. "The proxy statement states that, in connection with negotiating the merger agreement, Amazon had preliminary discussions with certain Whole Foods executive officers regarding Amazon's desire to retain such officers following the closing," the suit noted. "However, the proxy fails to disclose the timing and nature of all communications regarding the future employment and/or benefits relating to Whole Foods management."
