LISBON, May 15 (Reuters) - Portugal's largest construction company, Mota-Engil (MOTA.LS), beat forecasts with a 9 percent rise in first-quarter profit and its order book was swelled by new construction and engineering deals at home and in Angola. Net profit rose to 2.4 million euros ($3.25 million) as revenue increased 12 percent to 430 million euros.

Five analysts surveyed by Reuters had estimated, on average, a net profit of 600,000 euros on revenue of 438 million euros. [ID:nLE391203]

Mota's order backlog increased to 2.67 billion euros at the end of the first quarter from 2.64 billion at the end of last year, with the new business in Angola and Portugal compensating for a lower rate of orders in its environment and services division in other markets.

It said it expected its order book to continue to grow at a similar pace, which would support revenue growth.

Revenue in its construction and environment and services units rose 12 percent and 21 percent, respectively, while transport concession revenues dipped 2 percent, the company said.

Mota shares rose nearly 2.4 percent to 3.214 euros in early trading, outperforming the broader market in Lisbon, which was up 1 percent. (Reporting by Andrei Khalip, editing by Will Waterman) ($1=.7377 Euro)
