Dear [Jacobs Partner],

As a valued Jacobs partner, I wanted to share with you some exciting news. Today we announced an agreement to acquire CH2M HILL Companies Ltd., a world-renowned design, engineering and program management firm, to create a premier $15 billion global solutions provider.

This transaction marks a major milestone for our company and our industry as we unite two leading, innovative companies with complementary capabilities, cultures and relationships. CH2M is a leader in key infrastructure and government service sectors that Jacobs has previously targeted for growth, including water, transportation, environmental and nuclear. We expect that applying CH2M’s advanced design, technical and program management expertise across Jacobs’ global footprint will enable us to deliver more differentiated end-to-end solutions to more clients in more geographies around the world.

As our business grows with our clients, we expect Jacobs’ partners to benefit from new and expanded growth opportunities as well. Indeed, we believe this transaction is a win-win for all of our stakeholders.

While we are excited about the transaction and our ability to serve as an even stronger partner for you, today’s announcement is just the first step. We expect to complete the transaction in Jacobs’ fiscal 2018 first quarter ending in December 2017, subject to the satisfaction of customary closing conditions, including regulatory approvals and approval by CH2M stockholders. Until that time, Jacobs and CH2M must continue to operate as separate companies, and it remains business as usual.

Please know that all operations at Jacobs are unchanged, your Jacobs contact remains the same, and all contracts are continuing in the normal course.

The partnerships we build remain important to Jacobs. As always, if you have any questions, please feel free to reach out to [me personally/your relationship manager] at XXX-XXX-XXXX or EMAIL.

On behalf of the Jacobs team, thank you for your continued support.

Sincerely,

INSERT NAME
