CH2M HILL — Letter to Stockholders

Dear CH2M HILL Stockholders,

The Board of Directors has reviewed and approved an amendment and restatement of the company’s Delaware USA Certificate of Incorporation.  We expect that the proposed changes to the Certificate of Incorporation, among other things, will provide the company with greater flexibility in raising additional capital and are intended to facilitate a third party minority investment in CH2M HILL’s capital stock by one or more large sophisticated investors.

The changes to the Certificate of Incorporation must also be approved by you, the stockholders.  In order to call a Special Meeting of the Stockholders to approve the amendment and restatement of the Certificate of Incorporation, we filed a preliminary proxy statement with the US Securities Exchange Commission on January 6, 2015. The preliminary proxy statement can be found at www.sec.gov and describes the proposed changes to the Certificate of Incorporation.  We expect to distribute a definitive proxy statement to stockholders on or around January 16, 2015 for your review and voting for approval.

We encourage you to review the Definitive Proxy carefully when you receive it.  If after reviewing the document you have questions about the proxy or the proposals described in the proxy, please submit them via our online form [link to www.ch2mstockholder.com/contact.asp].

Very truly yours,

/s/ Thomas M. McCoy

Executive Vice President, General Counsel & Secretary
