Ameresco Inc. (AMRC) experienced a significant intraday decline of 5.69% on Monday, as the stock moved sharply lower following the release of its first-quarter financial results.

The energy efficiency and renewable energy company reported an adjusted loss per share of $0.33 for Q1 2026, which missed the analyst consensus estimate of a $0.30 loss. The net loss attributable to common shareholders widened to $18.3 million, compared to a loss of $10.4 million in the prior-year period.

Furthermore, Ameresco revised its full-year 2026 adjusted earnings per share guidance downward to a range of $1.06 to $1.28, from its previous outlook of $1.10 to $1.35. The combination of a wider-than-expected quarterly loss and a reduction in the annual profit forecast drove negative sentiment among investors during the trading session.
