Sona Comstar Q1: consol revenue +54% YoY to ₹1,310 Cr, PAT ₹179 Cr; margins steady, DENSO EV JV

Sona Comstar (Sona BLW) delivered its highest-ever quarterly topline in Q1 FY27, with consolidated revenue (incl. net FX) up 54.0% YoY to ₹1,310 Cr — its stated best-ever revenue, BEV revenue and BEV revenue share — driven by the electrification order book and the Escorts Kubota railway business acquired in June 2025 (now a full-quarter contributor versus one month a year ago). Consolidated PAT rose to ₹178.5 Cr, up 46.7% YoY on a reported basis; adjusting for the ₹9.2 Cr acquisition-cost exceptional in the year-ago base (there is none this quarter), underlying PAT growth is ~36% — strong, but a notch below the headline print. Sequentially revenue was near-flat (+3% QoQ off a strong Q4) and PAT eased 4.5% QoQ. Margins held rather than expanded: net margin was 13.6% (vs 13.6% a year ago, 14.5% in Q4) and operating/EBITDA margin ~23.1% (vs 22.7% YoY, 24.4% in Q4), landing at the lower end of management's guided 23-25% EBITDA band — consistent with the prior concall warning of margin pressure from inflation and product mix. So the print meets guidance on both counts: it clears the 'strong growth on electrification' outlook and stays inside the margin band, though the QoQ step-down shows the cost pressure is real. Note the standalone-vs-consolidated divergence: standalone PAT (₹220.1 Cr, +83% YoY) is flattered by a ₹59.5 Cr dividend from a subsidiary and does not reflect operating performance — the consolidated ₹178.5 Cr is the number to anchor on. The quarter's defining event is strategic, not financial: on 22 July the company signed definitive agreements with DENSO (Japan) for two EV/hybrid powertrain JVs (51:49 both ways), and will slump-sell its existing EV motors & controllers business into a subsidiary in which DENSO buys 49% at an enterprise value of ₹1,750 Cr — completing the high-voltage piece of its electrification portfolio. Management framed the quarter as the launch of 'Sona Comstar 2.0', including an entry into robotics and physical AI, targeting a tenfold expansion over the next decade. A ₹1.80/share FY26 final dividend was approved at the 15 July AGM. Reliable Q1-specific street consensus could not be verified — the estimates surfaced (₹778-876 Cr revenue) were stale relative to the company's current run-rate — so the print is not scored against consensus here.
