1. What was announced today?

• The acquisition of CH2M provides Jacobs with a leading position in targeted high margin, high growth infrastructure and government services sectors, including water, transportation, environmental and nuclear.

• Until the transaction closes, which we expect to occur in Jacobs’ fiscal 2018 first quarter ending in December 2017, Jacobs and CH2M must continue to operate as separate companies, and it will be business as usual.

2. Who is CH2M?

• CH2M is a world-renowned design, engineering and program management firm, and is a leader in key infrastructure and government service sectors that Jacobs has previously targeted for growth, including water, transportation, environmental and nuclear.

• CH2M employs more than 20,000 people. The company leads the professional services industry in delivering sustainable solutions to promote positive societal, environmental and economic outcomes through the delivery of infrastructure. CH2M is ranked among the World’s Most Ethical Companies and top firms in environmental consulting and program management.

• We have worked with the CH2M team on numerous projects over the years and know them well.

• Our companies have complementary cultures and shared values that put people at the heart of the business and emphasize safety, sustainability, integrity and profitable growth.

• We believe this will enable us to successfully integrate our companies to create one of the most technically advanced solutions providers in the world.

3. What are the benefits of the transaction?

• The acquisition of CH2M provides Jacobs with a leading position in targeted high margin, high growth infrastructure and government services sectors, including water, transportation, environmental and nuclear.

• Following the close of the transaction, Jacobs is expected to be a leading water design firm, a leader in transportation, have among the broadest and deepest environmental capabilities in the industry, and achieve our objective of being a Tier 1 service provider to the global nuclear industry.

• By applying CH2M’s advanced design, technical and program management expertise across Jacobs’ strong global platform and deep and long-standing relationships, will enable us to deliver more solutions to more clients in both the government and private sector.

• By bringing CH2M and Jacobs together, we believe we will bring more solutions to our clients, give more opportunity to our employees and position Jacobs for even greater levels of success well into the future.

• While the announcement of our agreement with CH2M is a significant milestone, it is just the first step towards Jacobs and CH2M working together.

• Until the transaction closes, which we expect to occur in Jacobs’ fiscal 2018 first quarter ending in December 2017, Jacobs and CH2M must continue to operate as separate companies, and it will be business as usual.

• As always, we must remain focused on our day-to-day responsibilities and serving our clients, with an emphasis on safety and delivering sustainable solutions.

5. Will there be any changes to compensation or benefits plans?

• Based on employee feedback, we are currently evaluating our benefits.

• Jacobs is committed to competitive compensation and benefits plans that attract, reward and incentivize world-class talent, consistent with its rankings among Forbes Best Large Employers list and Fortune Magazine’s Most Admired Companies in the World list. At Jacobs, we strive to maintain competitive plans that attract, reward and incentivize talent, and if there are any changes as part of our work to achieve these objectives, we will inform employees in advance.

6. What are the plans for integrating the two companies? Who will lead the integration effort?

• We have identified a great deal of synergies between the two companies which provides tremendous opportunity to outperform our competition in winning business and working on the most exciting projects and programs around the world.

• Over the coming weeks, Jacobs and CH2M leadership will have more detailed discussions about how best to combine our two great companies in a way that builds on our collective successes and enables us to create a stronger organization moving forward.

• As part of this effort, Jacobs has formed an Integration Management Office (IMO) to oversee a comprehensive, focused and disciplined integration process.

• The IMO will be jointly led by senior executives from both companies on a dedicated, full-time basis, including Gary Mandel, Jacobs Executive Vice President of Integration, and Lisa Glatch, CH2M’s Executive Vice President for Growth and Sales.

• As a result of Jacobs’ acquisition of Aker Solutions Process & Construction business in 2011, Gary joined Jacobs as Executive Vice President of Operations overseeing various global portfolios including, upstream and downstream oil and gas business, as well as the heavy process, biopharma, infrastructure, consulting, module fabrication, specialty chemicals and mining and minerals markets.

• Gary previously served as Executive Vice President for Aker Solutions, overseeing their oil and gas, process, energy and government services business.

• Gary’s prior leadership experience in infrastructure and government services, coupled with his current experience at Jacobs and the fact that he has successfully navigated acquisitions makes him a great fit for this new role.

• Our priorities for the integration are – retaining and attracting the best talent, building on the strong culture foundations of both companies, ensuring base business performance, and developing and delivering cost and growth synergies.

• We are committed to regularly keeping employees posted on our progress and integrations plans through normal course communications channels, such as emails, JacobsConnect, a microsite (www.Jacobs.com/CH2M) dedicated to the transaction.

• Until the transaction closes, which we expect to occur in Jacobs’ fiscal 2018 first quarter ending in December 2017, Jacobs and CH2M must continue to operate as separate companies, and it will be business as usual.

7. When will the transaction be completed? What can we expect between now and the close of the transaction?

• We expect the transaction to close 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.

• Importantly, until the transaction closes, Jacobs and CH2M must continue to operate as separate companies, and it will be business as usual.

• We are committed to providing employees with updates as additional details are available.

• Although we expect synergies associated with certain redundancies, it is important to emphasize that the premise of this transaction is growth, and talent retention is a top priority.

• As we grow together, we expect this transaction will provide exciting career development opportunities for employees of both companies as part of a larger, more diversified, global organization.

• Our intent is to capitalize on the capabilities and talent of both organizations and to maintain a strong workforce in each of our combined operations.

• Our intent is to build on our collective successes and create a stronger combined organization moving forward.

14. How will this strategic combination benefit clients?

• We believe this transaction is a win-win for all of our stakeholders, including our clients.

• CH2M brings a strong leadership position in water, environmental and nuclear. Extending these complementary capabilities across Jacobs’ significant global operating platform will allows us to bring an expanded service offering to our customers around the world.

• The combination will create a premier global water business and positions us as a Tier 1 player in the global nuclear and environmental sectors.

• Transportation is a high growth industry and one in which resources are constrained due to the increasing magnitude of infrastructure needs globally. Combined, we can better serve our customers and execute mega-programs spanning highways, rail, aviation and ports – anywhere in the world.

• In the life sciences and semiconductor space, Jacobs and CH2M respectively are complementary global leaders, and together will have the ability to deliver full, integrated solutions that we expect to provide significant growth opportunities for our people and the company.

• Throughout the world, the need for Program Management Construction Management (PM/CM) has increased as the scale of projects and programs continue to grow. While both companies have strong skills in PM/CM, we believe great opportunities exists for our people to work on some of the world’s most exciting programs when we leverage CH2M’s portfolio of iconic projects.
