Whitestone REIT is providing supplemental disclosures to its definitive proxy statement concerning its previously announced merger with AREG Wizard Intermediate LP (Merger Sub) and related partnership merger. The company has faced twelve demand letters and three shareholder complaints alleging inadequate disclosures in the preliminary and definitive proxy statements. These lawsuits, filed in New York state courts, challenge the adequacy of disclosures related to the merger background, financial advisor engagements, and the fairness of the merger consideration. Whitestone REIT asserts that the allegations are without merit and that no supplemental disclosure is legally required, but is providing these updates to avoid litigation burden, moot claims, and prevent merger delays. The supplemental disclosures include revised information on the background of the merger, the engagement of JLL Securities as a financial advisor, and details regarding BofA Securities' fairness opinion. The company also clarified that as of July 1, 2026, Ares (the acquirer's affiliate) had not discussed post-closing employment or equity participation with Whitestone management. Additional details are provided on non-disclosure agreements with potential bidders and precedent transaction analysis, including multiples for comparable REIT transactions. Historical trading prices, equity research analyst price targets, and net asset value per share estimates for Whitestone REIT are also updated. The special meeting of shareholders to vote on the merger is scheduled for July 9, 2026.
