On August 30, 2023, James W. Blake informed the Board of Directors (the ?Board?) of HarborOne Bancorp, Inc. (the ?Company?) of his decision to retire as a Class III director of the Company and HarborOne Bank effective August 31, 2023. Mr. Blake has served on the Board of Directors of HarborOne Bank and its predecessor institutions since 1995. The Company?s management team and the Board would like to extend their gratitude to Mr. Blake for his nearly thirty years of loyal service.

In connection with his announcement of his intention to retire, the Compensation Committee of the Board, as Administrator of the HarborOne Bancorp, Inc. 2020 Equity Incentive Plan, voted to partially accelerate the vesting of an award of shares of restricted stock that was granted to Mr. Blake on March 1, 2023 so that 1,905 shares will vest on August 31, 2023. These shares were originally scheduled to vest on March 1, 2024. Also on August 30, 2023, the Board reclassified the members of the Board into three classes of nearly equal size following the retirement of Mr. Blake.

To effect this change, Joseph F. Casey resigned as a Class I director whose term was scheduled to expire at the annual meeting of stockholders to be held in 2026 and was immediately reappointed as a Class III director to stand for re-election at the annual meeting of stockholders to be held in 2025. The Company and Mr. Casey did not enter into any new plan, contract, arrangement or compensatory plan in connection with his resignation and reappointment, and there is no arrangement or understanding between him and any other person pursuant to which he was appointed to serve as a Class III director. Mr. Casey?s resignation and reappointment were effected solely to reclassify the Board, and for all other purposes his service on the Board is deemed to have continued uninterrupted without any break in service.
