 EXPLANATORY NOTE

Rexford Industrial Realty, Inc. (the “Company”) is filing this Amendment No. 1 on Form 10-Q/A (this “Amendment”) to amend its Quarterly Report on Form 10-Q for the quarter ended June 30, 2015, originally filed with the Securities and Exchange Commission (the “SEC”) on August 10, 2015 (the “Original 10-Q”). The purpose of this Amendment is to clarify certain prior disclosures.  This Amendment contains changes to Part 1—Item 4 (Controls and Procedures) and Part II—Item 6 (Exhibits).

In accordance with Sections 302 and 906 of the Sarbanes-Oxley Act of 2002, currently dated certifications of the Company’s principal executive officers and principal financial officer are attached to this Form 10-Q as Exhibits 31.1, 31.2, 31.3, 32.1, 32.2 and 32.3. Part II—Item 6 has not been amended in any respect from the Original 10-Q, except for the amended text of the aforementioned Exhibits.

This Amendment should be read in conjunction with the Original 10-Q and the Company’s other filings made with the SEC subsequent to the filing of the Original 10-Q on August 10, 2015. The Original 10-Q has not been amended or updated to reflect events occurring after August 10, 2015, except as specifically set forth in this Amendment.

Evaluation of Disclosure Controls and Procedures

We maintain disclosure controls and procedures (as defined in Rule 13a-15(e) or Rule 15d-15(e) under the Securities Exchange Act of 1934, as amended, (the “Exchange Act”) that are designed to ensure that information required to be disclosed in our reports under the Exchange Act is processed, recorded, summarized, and reported within the time periods specified in the Security and Exchange Commission’s rules and forms and that such information is accumulated and communicated to management, including the Co-Chief Executive Officers and Chief Financial Officer, as appropriate, to allow for timely decisions regarding required disclosure.

In designing and evaluating the disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives, and management is required to apply its judgment in evaluating the cost-benefit relationship of possible controls and procedures.

As required by SEC Rule 13a-15(b), we carried out an evaluation, under the supervision and with the participation of management, including our Co-Chief Executive Officers and Chief Financial Officer, of the effectiveness of the design and operation of the disclosure controls and procedures as of June 30, 2015, the end of the period covered by this report.

As noted below, management is responsible for establishing and maintaining adequate internal control over financial reporting.  Due to a clerical error, however, certain clauses in the certifications required by Section 302 of the Sarbanes-Oxley Act of 2002 relating to designing, establishing and maintaining internal control over financial reporting were inadvertently omitted.  As a result of this clerical error, our Co-Chief Executive Officers and Chief Financial Officer conclude that our disclosure controls and procedures were not effective at the reasonable assurance level as June 30, 2015.

The Company has implemented additional form requirement checks, effective immediately, to ensure the effectiveness of our disclosure controls and procedures in future periods.

Changes in Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting. No changes to our internal control over financial reporting were identified that occurred during the period covered by this report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
