·                  Q3 revenue declines six percent to $1.28 billion

·                  Charges for two fixed-price projects drive $108 million operating loss

·                  Net income of $16 million; $0.40 per diluted share, reflecting pension redesign tax benefit

·                  Client-centric operating model to yield $90—$100 million in annual savings

DENVER, Colo.: Jan. 19, 2017 — CH2M today reported results for the third quarter ended Sept. 30, 2016, noting revenue of $1.28 billion versus $1.37 billion a year ago. Third-quarter net income of $16 million, or $0.40 per diluted share, included a tax benefit of $46 million related to a pension plan redesign. A year ago, CH2M posted $39 million in net income, or $1.22 per diluted share.

Charges for two unfavorable, at-risk construction projects negated operating income, including a $59 million charge for CH2M’s share of estimated cost increases for delays and productivity shortfalls on a fixed-price, engineer-procure-construct power plant project in Australia, the final contract in the fixed-price power EPC business the company announced it was exiting in the third quarter of 2014. In addition, CH2M recorded a charge of $66 million for higher cost estimates on a fixed-price, design-build tollway project in Texas. In both cases, the charges include no recovery assumptions for change orders and claims, which the company continues to pursue aggressively.

As a consequence of the cost growth on these two projects, the company used $130 million in cash from operations year-to-date, compared with $78 million generated during the same period in 2015.

“It’s frustrating when the same two legacy projects keep weighing on our financial performance, especially because they overshadow improvements in our core business, which remains sound despite the headwinds our broader industry is facing,” said CH2M Chairman and CEO Jacqueline Hinman. Describing plans launched during the quarter to transition the firm’s operating model, Hinman said, “Building on the success of our client-centric strategy, we’re creating a competitively distinct

operating model focused on discrete client sectors, rather than common location-based or vertical-market models. We’ll become one of the first in our industry to align completely around our clients, unlocking global, best-practice expertise and proven delivery methods to drive greater safety, innovation, quality and efficiency across project lifecycles. We see this as a game-changer for our clients and all of our stakeholders.”

While revenue backlog is down from last year due to several large design-build water projects that are winding down and which are expected to be replaced this year, Hinman cited a 30-percent surge in gross margin won from new contracts with the firm’s top 100 clients as the catalyst for CH2M to fully operationalize the client-centric strategy. “Since moving to client-focused account management last year, we’ve sustained healthy revenue backlog of nearly $9 billion, and our gross margin opportunity pipeline has grown by 35 percent.”

The operating model change, slated to deliver $90-100 million in annual savings upon full implementation in the first quarter of 2017, will establish a simplified structure aligned around three client sectors: national governments; state and local governments; and private-sector clients, enabling a seamless interface across practice disciplines, backed by centralized

corporate functions. By eliminating activities duplicated in its old matrix structure, the firm expects to free up capacity to invest in common tools, processes, technology, innovation and employee development. CH2M plans to record pretax charges of $50-70 million to implement the change, primarily for severance benefits for affected employees and facilities consolidation costs.

CH2M has filed a Form 8-K dated January 18, 2017 and an amended Form 10-K/A for the year ended December 25, 2015 due to the determination that pre-tax cost growth on a fixed-price, design build tollway project in Texas of $21 million recorded in the 4th quarter of 2015 should have been reflected as $18 million in the 2nd quarter of 2015 and $3 million in the 3rd quarter of 2015. There is no change to the amounts previously reported for the full year ended December 25, 2015.

Business segments and operating results

Environment and Nuclear

The Environment and Nuclear segment grew third-quarter revenue by 32 percent to $559 million, noting higher volumes associated with a large, multi-year nuclear project in Canada commenced late in 2015, and additional environmental work serving the U.S federal government. The business posted $29 million in operating income in the quarter—up 38 percent from a year ago—reflecting reduced selling, general and administrative costs and incremental income from the Canadian nuclear project.

Water

Revenue in the Water segment fell 13 percent to $298 million in the quarter, as growth from two large flood-management programs was offset by greater volume declines for several contracts reaching completion and dampening effects from the economic distress in the energy industry and Puerto Rico. The business boosted operating income by 25 percent to $31 million, benefiting from an improved mix of higher margin consulting services as well as a gain on the acquisition of a controlling interest in one of our joint ventures.

Transportation

The Transportation segment’s revenue declined six percent to $235 million during the quarter. Despite increased project volume in Canada, the fixed-price, design-build tollway project in Texas clouded much of the segment’s progress, as well as reduced work attributed to economic weakness in the Middle East and a negative currency effect on the British Pound for work in the United Kingdom. Further changes for the aforementioned fixed-price, design-build contract again drove up estimated costs to complete the project by $66 million during the quarter, which drove the business to a $58 million operating loss.

Energy and Industrial

The Energy and Industrial segment revenue declined 27 percent to $211 million in the third quarter compared with a year ago, reflecting lower volume, project scope, and client concessions on services, operations and maintenance contracts given the prolonged oil and gas industry slump in the U.S., Canada and Middle East. The segment operating loss in the current quarter was $3 million.

Power EPC (Engineer-Procure-Construct)

In the Power EPC business that the firm is exiting, CH2M recorded an operating loss of $107 million primarily due to the consolidated joint venture caused by increased costs to complete the above-referenced fixed-price EPC project in Australia.  CH2M’s share of the project loss was $59 million.

Outlook

For the full-year 2016 outlook, CH2M currently expects essentially flat revenue and lower earnings compared with the prior year’s results.

Reconciliation of Non-GAAP Financial Measures and Regulation G Disclosure

To supplement our consolidated financial statements, which are presented in accordance with U.S. generally accepted accounting principles (GAAP), we provide additional measures of net (loss) income attributable to CH2M and net (loss) income per diluted common share attributable to CH2M adjusted to exclude or deduct certain costs, charges or expenses. CH2M management believes these non-GAAP financial measures, when considered together with the GAAP financial measures, provide information that is useful to investors in understanding period-over-period operating results separate and apart from items that may, or could, have a disproportionately positive or negative impact on results in any particular period. CH2M management also believes these non-GAAP financial measures enhance the ability of investors to analyze CH2M’s business trends and to understand CH2M’s performance. Any analysis of non-GAAP financial measures should be used only in conjunction with results presented in accordance with GAAP.

A reconciliation of these non-GAAP financial measures with the most directly comparable financial measures calculated in accordance with GAAP follows:

(A) Adjustments relate to 1) revenue from our Power EPC business of ($23 million), and 2) costs incurred related to the 2016 Restructuring Plan of $3 million (or $0.11 per diluted share), after-tax loss from our Power business of $37 million (or $1.49 per diluted share) and tax benefit of pension redesign of $46 million (or $1.79 per diluted share).

(A) Adjustments relate to 1) revenue from our Power EPC business of $61 million, and 2) costs incurred related to the 2014 Restructuring Plan and include after-tax restructuring charges of $6 million (or $0.19 per diluted share) and after-tax income from our Power business of $1 million (or $0.05 per diluted share).

(A) Adjustments relate to 1) revenue from our Power EPC business of ($8 million), and 2) costs incurred related to the 2016 Restructuring Plan of $3 million (or $0.11 per diluted share), after-tax loss from our Power business of $103 million (or $3.87 per diluted share) and tax benefit of pension redesign of $46 million (or 1.85 per diluted share).

(A) Adjustments relate to 1) revenue from our Power EPC business of $132 million, and 2) costs incurred related to the 2014 Restructuring Plan and include after-tax restructuring charges of $17 million (or $0.61 per diluted share).

Reconciliation of Non-GAAP Financial Measures and Regulation G Disclosure (continued)

Notes:

Costs for the 2014 Restructuring Plan are associated with our activities to reduce overhead costs and achieve important business objectives, including improving efficiency, reducing risk and providing more long-term value for its stockholders.

Costs for the 2016 Restructuring Plan are associated with our activities to more fully align global operations with the Company’s client-centric strategy, including a simplified organization structure and streamlined delivery model to achieve higher levels of profitable growth and primarily related to employee severance and termination benefits and lease termination fees.

Adjustments for revenue and after-tax income (loss) related to our Power EPC business remove the results of this business unit. In the first quarter of 2014, we shifted our focus away from pursuing and contracting fixed price EPC power projects, and elected to exit the Power EPC business.

The tax benefit of pension redesign relates to an agreement we made with the Trustees of the largest defined benefit pension plan that came with a prior acquisition to redesign our obligations in this scheme to better ensure the sustainability of the acquisition over the long term.
