SCHEDULE 13D

This amendment reflects, among other things, that the reporting persons identified below no longer hold more than five percent of the Common Stock (as defined below) of Coastway Bancorp, Inc. So, the reporting persons are no longer required to file a Schedule 13D to report their holdings of Common Stock, and upon the filing of this amendment, the reporting persons will cease to mandatorily report their holdings of Common Stock on Schedule 13D.

This amended Schedule 13D (this “Schedule 13D”) is being filed on behalf of MHC Mutual Conversion Fund, L.P., a Texas limited partnership (the “Fund”), Clover Partners, L.P., a Texas limited partnership and the general partner of the Fund (the “GP”), Clover Partners Management, L.L.C., a Texas limited liability company and the general partner of the GP (“Clover”), and Johnny Guerry, the managing partner of Clover (collectively, the “MHC Mutual Conversion Fund Group”), relating to common stock ($0.01 par value) (the “Common Stock”) of Coastway Bancorp, Inc., a Maryland corporation (the “Issuer” or the “Company”).

Specifically, this Schedule 13D relates to Common Stock of the Issuer purchased by the GP through the account of the Fund. The Fund may direct the vote and disposition of the 170,100 shares of Common Stock it holds directly. The GP serves as the investment adviser and general partner to the Fund and may direct the vote and disposition of the 170,100 shares of Common Stock held by the Fund. Clover serves as the general partner of the GP and may direct the GP to direct the vote and disposition of the 170,100 shares of Common Stock held by the Fund. As the managing partner of Clover, Mr. Guerry may direct the vote and disposition of the 170,100 shares of Common Stock held by the Fund.

This Schedule 13D is also being filed on behalf of Mike I. Shafir. Mr. Shafir beneficially owns in the aggregate 3,750 shares of the Common Stock.

By virtue of the MHC Mutual Conversion Fund Group and Mr. Shafir coordinating their activities with regard to a potential proxy contest, as reflected in the attached Notice of Intent to Nominate Directors, dated December 22, 2017, the MHC Mutual Conversion Fund Group and Mr. Shafir may be deemed to constitute a “group” for purposes of Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”). Mr. Shafir is an employee of Clover Partners, L.P. The MHC Mutual Conversion Fund Group expressly disclaims beneficial ownership of securities held by Mr. Shafir, and Mr. Shafir expressly disclaims beneficial ownership of securities held by the MHC Mutual Conversion Fund Group.

Item 4.

The Reporting Persons purchased the Common Stock for investment purposes. The intent of the Reporting Persons is to influence the policies of the Issuer and assert shareholder rights, with a goal of maximizing the value of the Common Stock.

Consistent with its investment purpose, the Reporting Persons may engage in communications with one or more officers of the Issuer and/or one or more members of the board of directors of the Issuer, and/or one or more representatives of the Issuer regarding the Issuer, including, but not limited to its business, management, operations, assets, capitalization, financial condition, governance, strategy and future plans.

Mr. Shafir notified the Company that he intended to nominate himself and Mr. David Verlander for election to the Board of Directors of the Company at the 2018 Annual Meeting of Shareholders on the WHITE proxy card.

The Reporting Persons may, at any time and from time to time, review or reconsider their position and/or change their purpose and/or formulate plans or proposals with respect thereto.
