James C. Mastandrea, a former CEO and one of Whitestone REIT's largest shareholders with 1.1 million shares, is nominating six independent candidates to replace the entire board at the 2026 Annual Meeting. Mastandrea contends the company has underperformed, trades at a valuation discount, and has ignored multiple acquisition offers despite owning valuable real estate assets in high-growth markets. The dissident slate seeks to unlock shareholder value through asset sales and improved board oversight.
