IRVING, TEXAS — February 20, 2018 — Fluor Corporation (NYSE: FLR) today announced financial results for its fiscal year ended December 31, 2017. Including the impact of recently enacted U.S. tax reform legislation, earnings attributable to Fluor in 2017 were $191 million, or $1.36 per diluted share. Excluding these one-time tax effects of $37 million, or $0.27 per diluted share, earnings attributable to Fluor were $228 million or $1.63 per diluted share. This compared to 2016 earnings of $281 million, or $2.00 per diluted share. Consolidated segment profit for the year was $545 million, compared to $744 million a year ago. Revenue of $19.5 billion in 2017 compares to $19.0 billion in the prior year. Full year new awards were $12.6 billion, including $5.4 billion in Energy, Chemicals & Mining, $2.6 billion in Industrial, Infrastructure & Power, $2.6 billion in Government and $2.0 billion in Diversified Services. Consolidated backlog at year-end was $31 billion.

“Over the past year, we continued strengthening our integrated solutions offering, maintaining a cost-efficient organization and developing predictive analytics and other tools to enhance our project execution capability,” said David Seaton, Fluor chairman and chief executive officer. “As we go into 2018, these actions should serve us well with clients across the diverse markets we serve expressing increased optimism in pursuing advantaged projects.”

Corporate G&A expense for 2017 was $192 million, compared with $191 million a year ago. Expenses for the year were impacted by foreign currency exchange losses. Fluor’s cash and marketable securities at the end of the year was $2.1 billion. During 2017, the company generated $602 million in cash flow from operating activities and paid out $118 million in dividends.

Fourth Quarter Results

Earnings for the fourth quarter of 2017 were $60 million, or $0.43 per diluted share. Excluding the tax effects of $37 million, or $0.27 per diluted share, the company’s net profit was $97 million, or $0.70 per diluted share. Results for the quarter include an after-tax charge of $45 million, or $0.32 per diluted share, for estimated cost increases on a downstream project and a power project. Earnings for the fourth quarter of 2016 were $70 million, or $0.50 per diluted share. Segment profit for the fourth quarter of 2017 was $194 million, down from $249 million a year ago. Corporate G&A expenses in the fourth quarter of 2017 were $54 million, compared with $56 million a year ago. Revenue for the quarter was $5.0 billion and new awards were $3.2 billion.

Outlook

For 2018, the Company is establishing its initial EPS guidance at a range of $3.10 to $3.50 per diluted share. Guidance for 2018 assumes an increase in oil and gas, mining and infrastructure opportunities, and reflects the new revenue recognition standard and our current interpretation of recently enacted tax reform legislation in the United States. Based on our current interpretation and analysis, we expect the benefit of the new revenue recognition standard and U.S. tax reform will be approximately $0.75 to $0.95 per diluted share, a majority of which can be attributed to the new revenue recognition standard.

Fluor’s Energy, Chemicals & Mining segment reported segment profit of $455 million, compared to a segment profit of $401 million in 2016.  Results for the year include a $44 million revision related to estimated cost increases on a downstream project.

Non-GAAP Financial Measures

This press release contains a discussion of consolidated segment profit that would be deemed a non-GAAP financial measure under SEC rules. Segment profit is calculated as revenue less cost of revenue and earnings attributable to noncontrolling interests excluding: corporate general and administrative expense; interest expense; interest income; domestic and foreign income taxes; and other non-operating income and expense items. The company believes that consolidated segment profit provides a meaningful perspective on its business results as it is the aggregation of individual segment profit measures that the company utilizes to evaluate and manage its business performance. A reconciliation of this measure to earnings (loss) before taxes is included in the press release tables. In addition, this press release contains a discussion of earnings and diluted earnings per share, excluding the effects of recently enacted tax reform legislation, that would be deemed non-GAAP financial measures.  The company believes the exclusion of the tax impact allows investors to evaluate the company’s ongoing earnings and to make meaningful period-over-period comparisons.
