EXPLANATORY NOTE

Pursuant to Rule 13d-2 promulgated under the Act, this Schedule 13D/A (this “Amendment No. 4”) amends the Schedule 13D filed on September 25, 2015 (the “Original Schedule 13D”), as amended on December 2, 2015 (“Amendment No. 1”), March 14, 2016 (“Amendment No. 2”) and July 10, 2017 (“Amendment No. 3”) (the Original Schedule 13D, Amendment No. 1, Amendment No. 2, Amendment No. 3 and this Amendment No. 4 are collectively referred to herein as the “Schedule 13D”). This Amendment No. 4 relates to the Common Stock, par value $0.01 per share (“Common Stock”), of Hawaiian Telcom Holdco, Inc. (the “Company”), a corporation organized under the laws of the State of Delaware. Capitalized terms used herein but not otherwise defined have the meanings ascribed to such terms in the Original Schedule 13D as amended by Amendment No. 1, Amendment No. 2 and Amendment No. 3.

Item 4. Purpose of the Transaction

Item 4 of the Schedule 13D is hereby amended to include the following:

On July 2, 2018, pursuant to the Merger Agreement, at the effective time of the Merger, each share of Common Stock and each restricted stock unit of the Company was converted, at each Reporting Person’s option and subject to proration procedures as set forth in the Merger Agreement, into (i) 1.6305 common shares of Parent, (ii) 0.6522 common shares of Parent plus $18.45 in cash or (iii) $30.75 in cash, in each case without interest and with fractional shares paid in cash. Because the proration procedures have not been completed as of the date of this filing, it is not possible to determine the exact merger consideration to be received by each Reporting Person for each share of Common Stock and restricted stock unit disposed of in the Merger. The closing price of Parent’s common shares on July 2, 2018 was $15.65. As a result of the closing of the Merger, the Reporting Persons ceased to be the beneficial owner of any shares of Common Stock.

Item 5. Interest in Securities of the Issuer

Items 5(a)-(e) of the Original Schedule 13D are hereby amended and restated as follows:

(a) and (b) The Reporting Persons do not beneficially own any shares of Common Stock.

(c) Except as described in Item 4 of this Amendment No. 4, the Reporting Persons have not effected any transactions with respect to the Company’s Common Stock during the past sixty days.

(d) Not applicable.

(e) The Reporting Persons ceased to be the beneficial owners of 5% or more of the Company’s Common Stock on July 2, 2018.

After reasonable inquiry and to the best of our knowledge and belief, the undersigned certify that the information set forth in this statement is true, complete and correct.
