Explanatory Note

On November 8, 2012 (the “Original Filing Date”), Hawaiian Electric Industries, Inc. and Hawaiian Electric Company, Inc. (the “Companies”) filed with the Securities and Exchange Commission (the “Commission”) the Companies’ Quarterly Report on Form 10-Q for the quarterly period ended September 30, 2012 (the “Quarterly Report”). On April 8, 2013, the Companies filed Amendment No. 1 on Form 10-Q/A (Amendment No. 1) in response to communications with the Commission in connection with a request for confidential treatment with respect to certain portions of Exhibits 10.2, 10.3, and 10.4 originally filed with the Quarterly Report.  In preparing Exhibits 10.2 and 10.3 (the “Exhibits”) for Amendment No. 1, the Company inadvertently included certain redactions to the Exhibits. This Amendment No. 2 on Form 10-Q/A (this “Amendment No. 2”) is being filed for the sole purpose of filing revised versions of the Exhibits to correct such redactions, which supersede in their entirety the Exhibits filed with the Quarterly Report and Amendment No. 1.

Except for the revised Exhibits, this Amendment No. 2 does not amend any other information set forth in the Quarterly Report or Amendment No. 1. This Amendment No. 2 speaks as of the Original Filing Date, does not reflect any events that may have occurred subsequent to the Original Filing Date, and does not modify or update in any way any disclosures made in the Quarterly Report or Amendment No. 1. Additionally, in connection with the filing of this Amendment No. 2 and pursuant to Rule 12b-15 of the Securities Exchange Act of 1934, new certifications of the Companies’ respective principal executive officer and principal financial officer are also attached as exhibits hereto.

The following exhibits are filed as a part of this report:
