Is Tecogen making money or losing money?
No, Tecogen is currently not making money — the company is losing money with a negative profit margin of -37.2%, a substantial loss. That means the business loses money on every dollar of revenue.

The bankruptcy risk of Tecogen is rated as elevated. Altman Z2 (a model for assessing financial distress) is -2.55 — that places the company in the weak zone. This is a probability based on the numbers, not a verdict — bankruptcy is not imminent.

For the industri sector, anything above 150% counts as elevated — that raises the financial risk, especially if interest rates rise or earnings fall. Note: D/E levels are highly sector-specific — a bank at 300% debt is normal, a tech stock at 300% is extremely leveraged. Always compare with similar companies in the same sector.
