News Release

FLUOR REPORTS FIRST QUARTER RESULTS

IRVING, TEXAS — April 30, 2015 — Fluor Corporation (NYSE: FLR) today announced financial results for its first quarter ended March 31, 2015. Net earnings attributable to Fluor for the first quarter were $144 million, or $0.96 per diluted share, compared to $149 million, or $0.92 per diluted share a year ago. Consolidated segment profit for the quarter was $276 million, compared to $268 million in the first quarter of 2014. Segment profit results reflect continued improvement in Oil & Gas as well as Government, partly offset by declines in the Industrial & Infrastructure segment’s mining and metals business line. Revenue for the first quarter was $4.5 billion, down from $5.4 billion last year, primarily due to continued reductions in the mining and metals business line.

New awards for the quarter were $4.4 billion, including $2.9 billion in Oil & Gas and $1.4 billion in Industrial & Infrastructure. Consolidated backlog at the end of the quarter was $41.2 billion, up from $40.2 billion a year ago.

“Our ability to provide clients with capital efficient project execution through our integrated solutions model continues to gain traction, as evidenced this quarter by strong Oil & Gas performance,” said Chairman and Chief Executive Officer David Seaton. “While bookings

may be slower over the near term, we continue to see a number of high quality world scale opportunities.”

Corporate G&A expense for the first quarter of 2015 was $41 million, compared with $38 million a year ago. During the quarter, the Company repurchased approximately $112 million worth of Fluor shares, and paid out $32 million in dividends to shareholders. Fluor’s cash and marketable securities balance remains strong at $2.2 billion.

Ending backlog was reduced by approximately $1.6 billion as a result of the strong dollar. Foreign exchange rates did not have a significant impact on earnings for the first quarter.

Outlook

Overall, the first quarter was consistent with the Company’s prior guidance for a slow start in 2015. As a result, the company is maintaining its 2015 guidance range of $4.40 to $5.00 per diluted share. This guidance excludes the effects of the previously announced termination and settlement of Fluor’s U.S. defined benefit pension plan which is expected in the latter part of 2015.

Business Segments

Fluor’s Oil & Gas business reported segment profit of $183 million, an increase from $139 million in the first quarter of 2014. Revenue of $2.5 billion declined from $2.8 billion a year ago primarily due to certain large projects progressing towards completion. Strong segment profit performance reflects increased contributions from refining projects awarded in 2014. New

awards for the segment totaled $2.9 billion, including a pipeline project in the United States. Ending backlog for the Oil & Gas segment rose 8 percent, from $25.8 billion a year ago, to end the quarter at $27.8 billion.

The Industrial & Infrastructure group reported segment profit of $71 million, a 27 percent decline from $97 million in the first quarter of 2014. Revenue for the quarter was $1.1 billion, down from $1.6 billion a year ago. Revenue and segment profit results reflect a decline in contributions from the mining and metals business line. New awards for the first quarter were $1.4 billion, primarily for mining and metals and industrial services customers. Backlog at quarter end was $7.3 billion, down from $9.8 billion a year ago, mainly due to project execution outpacing new award activity in the mining and metals and infrastructure business lines.

Segment profit for the Government group was $15 million, up modestly from $13 million a year ago. Revenue for the quarter improved 9 percent to $646 million, due to the increased execution activities on projects awarded in 2014. New awards totaled $74 million for the quarter, and ending backlog was $4.2 billion, up from $2.6 billion a year ago.

Segment profit for the Global Services segment was $15 million in the first quarter which compares to $21 million a year ago. Revenue was $130 million, down from $142 million last year. Results in the quarter were driven by reductions in the equipment business line’s activities in Afghanistan and Latin America.

Fluor’s Power group reported a segment loss of $9 million, compared to a loss of $1 million a year ago. Excluding NuScale expenses of $17 million in the first quarter and $13 million a year ago, segment profit was $8 million and $12 million respectively. Segment revenue for the quarter decreased 12 percent to $221 million, compared with $251 million a year ago, due to the completion of two major projects in 2014. New awards for the quarter were $114 million compared with $166 million in the first quarter of 2014. Ending backlog was $1.9 billion, which was comparable with a year ago.
