The company also highlights potential future synergies and benefits from the merger, though these are subject to various risks and uncertainties.

Management Comments

• Joseph F. Casey was appointed as a director due to his extensive banking, financial, and accounting experience, and strong customer and community relationships within Eastern's expanded market area.
• Michael J. Sullivan was appointed as a director due to his recognized legal expertise in governance, corporate compliance and security, and extensive experience with ethics, policy and regulatory matters, as well as his deep ties to the communities served by Eastern.

Industry Context

This acquisition represents a consolidation within the regional banking sector, a common trend as banks seek to achieve economies of scale, expand market share, and enhance their service offerings. The integration of HarborOne's operations and customer base into Eastern Bank is expected to strengthen Eastern's position in its eastern Massachusetts, southern and coastal New Hampshire, Rhode Island, and Connecticut markets. The banking industry continues to face pressures from changing interest rates, deposit composition, and regulatory environments, making strategic mergers a key driver for growth and resilience.

• By February 2026, Eastern will merge HarborOne Mortgage with and into Eastern Bank.

Key Dates

Recommendation

The completion of the merger is an expected event, and while it expands Eastern Bankshares' market and asset base, the immediate impact on share price may already be factored in. The filing outlines standard integration risks common to such transactions. A 'hold' recommendation is appropriate as investors should monitor the successful integration, realization of synergies, and management's ability to navigate the outlined industry pressures before making further investment decisions. The long-term benefits are yet to be fully realized and are subject to execution.
