Proposed $25.5 billion stock merger drives high materiality, with control shift, dilution, valuation uncertainty, and elevated near-term volatility

Key Facts

• Equity Residential entered into a stock-for-stock merger agreement with AvalonBay on May 20, 2026; the proposed transaction includes an AvalonBay asset contribution followed by AvalonBay’s merger into an Equity Residential subsidiary.
• Under the proposed merger, each outstanding AvalonBay common share would convert into 2.793 Equity Residential common shares, with former AvalonBay stockholders expected to own approximately 51% of the combined company and legacy Equity Residential shareholders approximately 49%.
• The proposed transaction is expected to close in the second half of 2026, subject to shareholder approvals and other customary conditions; the combined company would operate under a new name with dual headquarters in Chicago and Arlington.
• ERP Operating Partnership obtained commitments for up to $2.0 billion of senior unsecured bridge loans to help repay or refinance existing debt and fund merger-related fees and expenses, but any borrowing remains undetermined.
• The pro forma filing estimates aggregate merger consideration at approximately $25.5 billion, but the final purchase price could differ significantly because it will fluctuate with AvalonBay’s share price until completion.
