EXPLANATORY NOTE

On February 24, 2015, DreamWorks Animation SKG, Inc. (the “Company”) issued an earnings release announcing its results for the year ended December 31, 2014 and filed a Current Report on Form 8-K (the “Report”) in connection therewith. The press release included, among other things, a presentation of the Company’s Adjusted EBITDA, a non-GAAP financial measure as defined in Regulation G promulgated by the Securities and Exchange Commission (“Regulation G”), and Adjusted EBITDA (excluding the effects of the Company’s 2015 restructuring plan). As required by Regulation G, the press release included a table labeled “Adjusted EBITDA Reconciliations” in which the Company provided a reconciliation of the non-GAAP financial information presented to the most directly comparable GAAP financial information. In the portion labeled “Reconciliation of Net (Loss) Income to Adjusted EBITDA,” the Company inadvertently included a line item titled “Other impairments” which should not have been included. Further, in the portion labeled “Reconciliation of Adjusted EBITDA to Cash (Used in) Provided by Operating Activities,” the Company inadvertently omitted a line item titled “Other impairments” which should have been included. This Amendment No. 1 to the Current Report on Form 8-K/A amends Items 2.02 and 9.01 of the Report to include a corrected earnings release which incorporates the foregoing revisions to Adjusted EBITDA and Adjusted EBITDA Reconciliations.

Attached and incorporated herein by reference as Exhibit 99.1 is a corrected earnings release. The corrected earnings release includes the revised Adjusted EBITDA and Adjusted EBITDA Reconciliations for the periods indicated therein.

This information shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference to such filing.
