Ameresco's stock experienced a sharp after-market rise following the release of second-quarter 2026 financial results, as the energy infrastructure company delivered revenue that substantially exceeded Wall Street estimates and raised its outlook for the full year.
For the quarter, Ameresco reported revenue of $515.5 million, topping the roughly $467 million analysts had anticipated and representing a 9% increase from the year-ago period. Adjusted earnings per share were $0.20, in line with consensus estimates.
Beyond the headline figures, the company disclosed a milestone backlog update that amplified investor reaction. Ameresco announced $1.8 billion in new project awards during the quarter, of which $1.2 billion were tied to data-center projects - a high-growth focus area for the business. Total backlog rose 32% year-over-year to a record $6.73 billion, a level management said provides greater revenue visibility going forward.
Following the quarterly results, Ameresco raised its full-year 2026 adjusted EPS guidance to a range of $1.15 to $1.35, which sits above the prior analyst consensus of $1.10. The company also set a revenue target for the year of $2.00 to $2.20 billion.
The combination of a clear revenue beat, the record backlog supported by strong data-center demand, and an upward guidance revision came after a period in which the stock had faced notable downward pressure. Those factors produced an outsized after-hours response, with shares trading at $29.02 following the announcement and remaining well under the 52-week high of $44.93.
Analytically, the quarter offered a mix of validation and conditional upside. The revenue beat and backlog expansion increase near-term visibility into future revenue streams, especially given the sizable share of awards linked to data centers. At the same time, the market reaction underscores that sustained execution will be necessary for the stock to re-rate toward prior highs.
Summary takeaway: Ameresco posted stronger-than-expected revenue, matched EPS consensus, reported record backlog driven in large part by data-center projects, and raised full-year guidance - prompting a substantial after-hours stock rally.
