Aecom Technology Corp. on Thursday raised its full-year earnings outlook, despite reporting slightly lower first quarter profit.

The Los Angeles engineering and design company reported net income of $58 million (49 cents a share), compared with $59 million (51 cents) a year earlier. Revenue rose 21 percent to $1.9 billion.

Analysts surveyed by Thomson Reuters on average had expected per-share profit of 49 cents on revenue of $2.06 billion.

“We are pleased that we were able to achieve solid results even with challenging external events, which we believe speaks to the resilience of our diversified business model and to the agility of our team around the world,” said Chief Executive John Dionisio in a statement.

Aecom now expects to report full-year earnings of $2.35 to $2.40 a share, up from prior estimates of $2.25 to $2.35 a share

Dionisio said the increase was justified by “organic-growth opportunities around the world” and prospects for “a meaningful increase” in the company’s U.S. government business in the second half of the year.

Shares closed up $1.28, or 4.8 percent, to $28.03 in midday trading on the New York Stock Exchange.
