Waaree Energies — India's largest solar module maker — reported Q1 FY27 results on July 29, 2026: revenue surged 79% YoY to ₹7,932 crore, EBITDA rose 44% to ₹1,440 crore, but profit after tax (PAT) grew just 15% to ₹892 crore. The stock fell 4.3% on the news.
Revenue nearly doubled. Profit barely moved the needle. The market sold the stock 4.3%. That reaction is the lesson.
Here is how a CFO reads this. The gap between 79% revenue growth and 15% PAT growth is a margin compression story hiding in plain sight. Start at EBITDA — Waaree's operating earnings grew 44%, which sounds decent until you notice that EBITDA margin shrank from 22.5% to 18.2%. EBITDA margin is simply EBITDA divided by revenue; when it falls even as absolute EBITDA rises, it means costs are growing faster than sales. In solar manufacturing, that usually means raw-material costs (wafer, glass, encapsulant) or aggressive pricing to win orders.
Then zoom out further to PAT — profit after tax, the bottom line after depreciation, interest and taxes are stripped out. PAT margin fell from 16.8% to 11%. That additional compression between EBITDA and PAT tells you the company is carrying more capital-heavy infrastructure: ₹7,000 crore of cash is great, but a 10 GW cell plant under construction in Gujarat means depreciation is ramping up as new assets come online.
A CFO would ask: is margin compression temporary (mix shift, expansion costs) or structural (commodity cycle, pricing pressure)? Waaree's ₹61,500 crore order book says demand is not the problem. But orders don't protect margins. A CFO watches the spread between revenue growth and EBITDA growth like a hawk — because that spread is where value either compounds or quietly leaks away.
