Clean Science and Technology Limited

“Clean Science and Technology is a structurally sound specialty chemical business with genuine process-chemistry IP, zero debt, and a history of exceptional returns — but the primary moat product (MEHQ) faces demonstrable Chinese competitive erosion, the HALS diversification thesis has been repeatedly delayed, and at 30x forward earnings the stock still prices in a recovery that lacks a visible near-term catalyst. Probability-weighted returns over 5 years are insufficient (~2–4% CAGR) for the structural uncertainty carried. The right action is to monitor for an entry below INR 600 or for confirmed HALS scaling, whichever arrives first.”
