Summary

Core view: Windlas Biotech grew Q1 FY27 revenue 18% year-on-year to a record ₹248 crore, led by 29% growth in its generic formulations CDMO segment and 79% export growth. Reported PAT was roughly flat due to a ₹7.2 crore non-cash ESOP charge; excluding this, adjusted PAT grew 37%, which is the more meaningful measure of underlying earnings momentum.

Windlas Biotech is a CDMO formulations manufacturer for domestic branded-generics customers, with a growing exports business, delivering its 14th consecutive quarter of record revenue.
