Ameresco, Inc. entered a definitive contribution and equity purchase agreement with HASI to form Neogenyx Fuels, a biofuels joint venture valued at about $1.8 billion. Ameresco will contribute its biogas business for a 70% stake, while HASI invests $400 million for 30% via Class B units. Of this, $100 million will be paid to Ameresco at closing, roughly $58 million will reduce an existing construction and development loan, and the balance will fund the joint venture.
For Q1 2026, Ameresco generated $401.5 million in revenue, up 14% year over year, but reported a net loss attributable to common shareholders of $18.3 million, or ($0.35) per share. Adjusted EBITDA was $40.5 million. Awarded project backlog reached about $2.8 billion, with total project backlog of $5.3 billion and total revenue visibility of $10.6 billion.
The company updated its full-year 2026 outlook to reflect the expected consolidation of Neogenyx Fuels, guiding to revenue of $2.0–$2.2 billion, adjusted EBITDA of $250–$270 million, and Non-GAAP EPS of $1.06–$1.28. Ameresco expects to place 100–120 MWe of energy assets into service and forecasts that about 60% of 2026 revenue will occur in the second half.

The equity plan amendment would add 3,200,000 shares of Class A common stock to the existing pool, which the board estimates equals about 15.08% of fully diluted shares as of March 31, 2026 and would support roughly three years of grants. The company discloses a three-year average gross burn rate of 1.74% and an overhang of 10.17%, rising to 14.80% if the amendment is approved.
