Key Summary: James C. Mastandrea, a major Whitestone REIT shareholder, launched a proxy fight in January 2026 to replace the entire board, citing prolonged underperformance, NAV discount, weak growth, poor capital allocation, dilution, high costs, and governance failures, and in March 2026 formally nominated six independent candidates, criticizing the board for ignoring credible acquisition offers and arguing that a reconstituted board with real estate and capital markets expertise can restore discipline and unlock value through improved operations or potential asset sales. On July 9, 2026, Whitestone REIT announced that shareholders approved its all-cash acquisition by certain Ares Real Estate funds at a special meeting. Erez Asset Management launched an activist campaign against Whitestone REIT in March 2024, nominating two board candidates and criticizing underperformance, rejected buyout offers, poor capital allocation, high costs, debt, and weak governance; it filed multiple proxy materials, issued an investor presentation, and gained ISS support for its nominees while urging votes against certain incumbents, but despite its efforts and continued push for change, all of Whitestone’s nominees were ultimately re-elected at the May 2024 AGM. KBS Strategic Opportunity REIT built a 7.1% stake in Whitestone in 2017 (later 9.36%) and pushed for governance and compensation changes, including nominating trustees and proposing Board declassification; despite filing proxy materials and receiving ISS support, its nominees were not elected at the May 2018 AGM, though the declassification proposal passed, and KBS later reduced its stake to 4.99% by year-end 2018

James C. Mastandrea

On January 2, 2026, James C. Mastandrea, a long-time shareholder of Whitestone REIT, announced plans to file a preliminary proxy and nominate a full slate of six independent trustees at the 2026 annual meeting to replace the current board, citing years of share-price underperformance, persistent discounts to NAV, weak external growth, poor capital allocation, and excessive executive compensation. Mastandrea criticized the board for strategic missteps, dilution from equity issuance below NAV, shrinking portfolio size, elevated costs, litigation spending, and weak governance, arguing these failures have eroded shareholder value despite favorable Sun Belt market dynamics. He believes a reconstituted board with deep real estate and capital-markets expertise can reset strategy, restore accountability, improve operations and capital discipline, and ultimately unlock value through improved performance or a strategic sale or liquidation of assets.
