EXPLANATORY NOTE

The purpose of this Report is to amend the Current Report on Form 8-K of Willdan Group, Inc. (the “Company”) filed with the United States Securities and Exchange Commission on January 21, 2015 related to two separate acquisitions (the “Acquisitions”). On January 15, 2015, the Company acquired substantially all of the assets of 360 Energy Engineers, LLC (“360 Energy”) pursuant to the terms of an Asset Purchase Agreement, dated as of January 15, 2015 (the “360 Energy Agreement”), by and among the Company, Willdan Energy Solutions (“WES”), and 360 Energy. In addition, on the same date, the Company acquired all the outstanding shares of Abacus Resource Management (“Abacus”) pursuant to the terms of a Stock Purchase Agreement, dated as of January 15, 2015 (the “Abacus Agreement” and, together with the 360 Energy Agreement, the “Agreements”), by and among the Company, WES, Abacus and Mark Kinzer and Steve Rubbert (the “Abacus Shareholders”).

This Amendment No.1 to the Current Report on Form 8-K/A (“Amendment No. 1”) amends and supplements Item 9.01 of the original Form 8-K filed on January 21, 2015 (the “Initial Form 8-K”) to provide certain historical financial statements for 360 Energy and Abacus and certain pro forma financial information in connection with the Acquisitions. Any information required to be set forth in the Initial Form 8-K which is not being amended or supplemented pursuant to this Amendment No. 1 is hereby incorporated by reference. Except as set forth herein, no modifications have been made to the information contained in the Initial Form 8-K and the Company has not updated any information contained therein to reflect the events that have occurred since the date of the Initial Form 8-K. Accordingly, this Amendment No. 1 should be read in conjunction with the Initial Form 8-K.

Note Regarding Forward-Looking Statements

Statements and other information included in this Current Report on Form 8-K/A that are not historical facts, including statements about the Company’s plans, strategies, beliefs and expectations, as well as certain estimates and assumptions used by the Company’s management, may constitute forward-looking statements.  Forward-looking statements are subject to the safe harbor provisions of the Private Securities Litigation Reform Act of 1995.  Forward-looking statements speak only as of the date they are made and, except for the Company’s ongoing obligations under the U.S. federal securities laws, the Company undertakes no obligation to publicly update any forward-looking statement.

Forward-looking statements are subject to known and unknown risks and uncertainties and are based on estimates and assumptions that are subject to change or revision, including the estimates and assumptions used by the Company in preparing the pro forma financial information included in this Current Report on Form 8-K/A that could cause actual results to differ materially from those expected or implied by the forward-looking statements or the estimates or assumptions used.  Such forward-looking statements include, without limitation, the Company’s current expectations with respect to payment of the earn-out consideration and preliminary estimated adjustments to record the assets and liabilities of the Company at their respective estimates of fair values under acquisition accounting, and are based on current available information.

Actual results may differ materially from the forward-looking statements for a number of reasons, including additional information regarding the fair values of assets and liabilities becoming available, the performance of additional fair value analyses, and risk factors identified in the Company’s periodic filings with the SEC, including without limitation in the Company’s Annual Report on Form 10-K for the year ended December 27, 2013.  Factors other than those listed above also could cause the Company’s results to differ materially from expected results.
