KSB Q1 FY27: Consolidated PAT falls 19% YoY to ₹57 Cr on valves margin collapse

KSB's consolidated PAT for the quarter ended 30 June 2026 came in at ₹57.2 Cr, down 18.8% YoY from ₹70.4 Cr, even as revenue from operations grew a modest 3.6% YoY to ₹690.7 Cr (₹666.7 Cr). Sequentially the print looks much stronger — PAT is up 43.7% QoQ and revenue up 14.9% QoQ off a seasonally soft March quarter — but per the YoY-primary read this is a weak quarter: profit growth trailed revenue growth by a wide margin, and both operating margin (11.8% vs 13.7% YoY) and net margin (8.2% vs 10.4% YoY) compressed. No analyst consensus estimates for this specific quarter were found in a web search, so the print cannot be benchmarked against Street numbers; vsStreet is marked unknown rather than guessed. The margin compression is not evenly spread across the business. Segment data shows the Pumps business held up reasonably well — revenue of ₹581.0 Cr (+5.4% YoY) and segment profit of ₹65.0 Cr, roughly flat on ₹64.0 Cr YoY (margin ~11.2% vs 11.6%). The real damage is in Valves: revenue fell 4.8% YoY to ₹110.7 Cr and segment profit collapsed to ₹4.5 Cr from ₹17.8 Cr a year ago — a margin compression from 15.3% to 4.1%. A ₹5.0 Cr YoY drop in 'other unallocable income' (₹2.4 Cr vs ₹7.4 Cr) and a rise in finance costs (₹1.4 Cr vs ₹0.7 Cr) added further drag; together these items account for almost the entire ₹17.5 Cr YoY decline in consolidated PBT. Against management's own guidance from the last concall — 15-20% pump-segment revenue growth for CY2026 and EBITDA margins sustained around 13-14% — this quarter falls short on both counts: pump growth of 5.4% YoY is well below the guided band, and consolidated OPM of 11.8% sits below the 13-14% target, consistent with management's flagged commodity-cost watchpoint. The quarter's other developments — the switch of statutory auditor from Price Waterhouse to B S R & Co. LLP, confirmed via an AGM addendum and a revised (unchanged-numbers) results intimation in April — are procedural and don't bear on the operating numbers. No company press release commentary was available at the time of this analysis, so management's own framing of the quarter could not be cross-checked against the figures. Standalone PAT was ₹59.6 Cr (EPS ₹3.43) versus consolidated ₹57.2 Cr (EPS ₹3.29); the ₹2.4 Cr gap arises because consolidation strips out a ₹7.4 Cr associate dividend booked as standalone other income and replaces it with a smaller ₹4.2 Cr equity-method share of the KSB MIL Controls associate's profit — not a divergence in the underlying operating story, since both bases show the same revenue and cost trends.
