Star Cement Q1FY27: consolidated PAT falls 25% YoY to ₹74 Cr as OPM compresses to ~21%

Star Cement's consolidated revenue rose a modest 3.4% YoY to ₹942.9 Cr but fell 19.7% QoQ from Q4FY26's ₹1,173.6 Cr. Consolidated PAT for the period came in at ₹73.9 Cr (₹74.7 Cr attributable to shareholders), down 24.7% YoY from ₹98.2 Cr and 49.7% QoQ from ₹147.0 Cr; basic EPS fell to ₹1.85 from ₹2.44 a year ago and ₹3.66 last quarter. Neither this quarter nor the year-ago quarter carried exceptional items, so the YoY decline is a clean, unadjusted comparison — no adjusted-vs-reported gap to reconcile. The compression sits squarely on operating margin: OPM fell to roughly 20.6% from 25.0% YoY and 26.4% QoQ, and NPM fell to 7.8% from 10.7% YoY, as power-and-fuel costs rose to ₹152.0 Cr from ₹141.4 Cr a year earlier even as revenue grew only 3.4%. This lines up with what management told the Street on the Q4FY26 call: a temporary ₹250-300 Cr fuel-cost hit across Q1-Q2 FY27 from supply-chain disruptions, only partly offset by price increases, with normalisation expected by Q2. On that specific cost-guidance dimension the quarter met what was flagged. The filing carries no volume disclosure, so the separately guided 10-12% FY27 cement volume growth target can't be checked against this statement. Pre-print brokerage coverage (Business Standard) had flagged sector-wide Q1FY27 margin pressure from roughly ₹250-300/ton cost inflation tied to West Asia-linked fuel costs, with normalisation expected around June/Q2 — directionally consistent with this print, though no company-specific consensus PAT figure could be found to call a precise beat or miss. This quarter's other corporate developments — a rejected promoter-reclassification application (Jul 16) and being named preferred bidder for an Assam mining lease (Jun 24) — have no direct P&L linkage this period. No management press release accompanying the filing was available to quote. The next test is whether OPM recovers toward the 25-26% band seen through FY26 in Q2FY27, per management's own normalisation claim; a continued sub-22% margin would suggest the pressure is more structural than transitory. The August 10, 2026 earnings call should clarify volume growth against the 10-12% FY27 guide and progress on the ₹600-700 Cr FY27 capex plan (Haryana/Bihar grinding units, Rajasthan/Assam clinker).
