Greetings, 

Thank you for banking with HarborOne. We are pleased to provide you with an update on the merger between HarborOne Bank and Eastern Bank. We recently received all the necessary regulatory approvals to complete the merger. On October 31, 2025, HarborOne Bank will officially join Eastern Bank under the Eastern Bank name.

WHAT TO EXPECT 

As of November 1, 2025, HarborOne customers may use any Eastern Bank ATM free of charge for cash withdrawals. In February 2026, the combined bank will complete the full transition of HarborOne Bank accounts and services to Eastern Bank.

In January 2026, you will receive a Welcome Package with more information on the seamless transition of your accounts and services.

FREQUENTLY ASKED QUESTIONS

Q: What does this merger mean to my banking relationship with HarborOne?

A: Until we complete the merger and integration of accounts and services, there is no immediate impact to your HarborOne Bank accounts and services or the relationship you have with your banking team. You should continue to bank as you normally would at HarborOne Bank locations and through HarborOne Bank Mobile and Online Banking. Until the completion of the integration in February, you should continue to use your current checks and ATM/Debit Card. Over the next several months, we will communicate with you about the upcoming merger and what you can expect along the way.

Q: What will happen to HarborOne Bank branches and bankers?

A: We are pleased to share that most HarborOne employees will join Eastern and most HarborOne branch locations will transition to become Eastern Bank branches following completion of the merger and integration to one bank. 

Due to overlap in the combined bank’s footprint, some HarborOne Bank branch locations and Eastern Bank branch locations will close.

The following HarborOne Bank branches are expected to close and consolidate to a nearby Eastern Bank branch. If you bank at any of these branches, you will receive additional information by mail.

64 Broad St., Boston, MA (distance to nearest branch is 0.30 miles, at One Federal St.)

14 West Broadway, Boston, MA (distance to nearest branch is 0.80 miles, at 470 West Broadway)

1608 Commonwealth Ave., Brighton, MA (distance to nearest branch is 0.90 miles, at 1952 Beacon St.)

473 Harvard St., Brookline, MA (distance to nearest branch is 0.60 miles, at 1354 Beacon Street)

1739 Massachusetts Ave., Cambridge, MA (distance to nearest branch is 0.60 miles, at 1720 Massachusetts Ave.)

101 Dudley St., Providence, RI (distance to nearest branch is 1.40 miles, at 180 Washington St., currently a HarborOne Bank location)

Q: When can I begin using Eastern Bank branches and ATMs?

A: Upon completion of the integration in February, you will be able to use any Eastern Bank branch. At that time, all transitioning HarborOne Bank locations and ATMs will have transitioned to Eastern Bank branch locations. As of November 1, 2025, HarborOne customers may use any Eastern Bank ATM free of charge for cash withdrawals.

Q: Does Eastern Bank offer FDIC insurance, and will my deposit accounts continue to be insured?

A: Like HarborOne Bank, Eastern Bank deposits are FDIC insured up to $250,000 per depositor, per account ownership category. The following is what you need to know about how your FDIC-insured deposit accounts may be impacted:

• If you have accounts at both Eastern Bank and HarborOne Bank, following the completion of the legal merger of the two banks in October 2025, under federal law, you will continue to receive the same FDIC coverage as if your accounts were still at separate banks for a six-month grace period after the merger.
• Certificates of Deposits (CDs) maturing after the six-month grace period will continue to receive separate FDIC insurance coverage until the first maturity date after the six-month grace period.
• CDs maturing within the six-month grace period that are renewed for the same terms (the same time period and dollar amount) as the original deposit will continue to receive separate FDIC insurance coverage until the first maturity date after the six-month grace period.
• CDs maturing during the six-month grace period that are renewed with different terms are separately insured only until the end of the six-month grace period.
• After the six-month grace period has passed, if your total aggregate account balances at the merged bank exceed $250,000, any excess may not be covered by FDIC insurance. If you will have amounts above $250,000 on deposit at the combined bank, please plan to speak with your banker or call 800-244-7592.
• For additional information about FDIC coverage, visit fdic.gov.

Q: Does Eastern Bank support local communities?

A: Eastern Bank believes deeply in supporting our local communities. This belief will continue to hold true throughout HarborOne Bank communities. The Eastern Bank Foundation is one of the largest corporate foundations in our region, and the support in the communities where both organizations currently operate will continue through grassroots grants to hundreds of local nonprofit organizations each year.

• Can I continue to use my HarborOne debit card? You will continue to use your HarborOne Debit Card after your accounts have transitioned to Eastern Bank. HarborOne cardholders will receive a new Eastern Bank Debit Card sometime later in 2026. You will be notified before we send a new Eastern Bank card. For any cardholders with expiring cards: if your debit card expires before March 2026, you will receive a new HarborOne debit card prior to your card expiration. If your debit card expires in or after March 2026, you will receive a new Eastern Bank debit card prior to your card expiration.  
  
  
• What are the terms of the merger? Eastern Bankshares, Inc., the parent company of Eastern Bank, will merge with HarborOne Bancorp, Inc., the parent company of HarborOne Bank and HarborOne Bank Mortgage. The combined franchise will have $31 billion in assets and be the largest Massachusetts-based bank.

• What is the expected timing of the merger? The merger needs to be approved by State and Federal Regulators, and HarborOne shareholders. We expect the merger will close in the fourth quarter of 2025, subject to required regulatory approvals and other conditions.

• Until the deal is approved, HarborOne and Eastern Bank will continue to operate independently. For now, there are no changes in how you bank with us and there is no need to take any action. Your relationship management and/or banking center team remain the same. We anticipate communicating proactively with you on how to prepare for any transition, as needed. 

• How are customers impacted? For now, there is no customer impact. Ultimately, the benefits for HarborOne customers are significant, including expanded convenience with over 100 branch locations, expanded access to a broader range of products and services, and a more robust wealth management capability. Over the coming months, we will provide additional details to our customers. 

• What are the plans for the branches? We expect most of HarborOne's 30 locations will be retained, including all 3 of the branches in Brockton. Additionally, all HarborOne and Eastern branch employees will be retained. We do not anticipate exiting any city or town where our combined network currently operates.

• Will HarborOne's community support and involvement continue? Our commitment to our communities will deepen with this merger. Our shared values, including a commitment to the communities we serve, make this partnership a natural fit. The Eastern Bank Foundation is one of the largest corporate foundations in our region and in combination with the HarborOne Foundation will dedicate $20 million in programming, including financial literacy and business resources currently offered through HarborOne U, to support the communities served by both banks, including in Brockton, Southeastern Massachusetts, and Rhode Island.
