Feb 19 (Reuters) - Quanta Services PWR.N on Thursday forecast 2026 profit above Wall Street estimates, as robust investments in AI-infrastructure boosts demand for the energy contractor's core electric segment.

Shares of the company rose 6% in premarket trading.

The Houston, Texas-based company expects full-year adjusted profit per share between $12.65 and $13.35, above analysts' estimate of $12.44 per share, according to data compiled by LSEG.

"The convergence of utility, power generation, and large-load industries continues to create significant opportunities," Quanta Services CEO Duke Austin said.

The company said, during the previous quarter's earnings call, it was well-positioned to leverage its capabilities in addressing growing electricity and infrastructure demand from data centers, manufacturing and reshoring, industrialization, electrification and power grid expansion.

The company — which provides infrastructure services for utility, renewable energy, technology, communications, pipeline and energy industries — benefits from robust investments in AI data centers from hyperscalers.

Quanta's adjusted profit for the quarter ended December 31 rose to $3.16 per share, from $2.94 per share a year ago. Analysts, on an average, expected a profit of $3.02 per share.

The company's fourth-quarter revenue rose to $7.84 billion, from $6.55 billion a year earlier. Analysts expected revenue of $7.37 billion.
