Winston Score History

The full picture

Ameresco is an energy services company that helps buildings and facilities use less energy and save money. It designs and installs upgrades like LED lighting, solar panels, and efficient heating systems for schools, hospitals, government buildings, and military bases across the United States and Canada. The company is one of the larger independent energy efficiency contractors in North America.

Ameresco makes most of its money in two ways: it charges upfront fees to build and install energy projects, and it also owns some of those systems long-term, collecting recurring revenue from energy savings or power sales. The company operates mainly in the U.S., with smaller operations in Canada and the U.K., and generates roughly $1.5 billion in annual revenue. Its long-term contracts with government clients provide some stability, but the business faces real risk from rising interest rates, which make financing large infrastructure projects more expensive and can slow down new project signings.

Growth Profile

When traditional metrics don't capture the full picture, these are the signals growth stock investors use instead.

Short runway — potential dilution ahead through share issuance

Cash watch

Ameresco has less than a year of cash at its current burn rate. Growth investors should watch for potential share dilution from future fundraising — that directly reduces your ownership.

The Winston Score above measures business quality today. Growth stocks often score lower because they invest in the future rather than maximising current profits. These metrics show what matters most for evaluating that future.
