JBML Q2: revenue +41% YoY, but OPM slips to 9.1%; consolidated PAT +74% tax-aided

Jay Bharat Maruti's consolidated revenue came in at ₹823.42 Cr for Q2 FY27, up 41.3% YoY (₹582.65 Cr) and 31.4% QoQ (₹626.79 Cr) — a sharp acceleration in topline. Consolidated PAT attributable to owners was ₹32.01 Cr, up 73.7% YoY and 46.5% QoQ, with basic EPS at ₹2.96 against ₹1.70 a year ago. Standalone tells the same story at ₹823.42 Cr revenue and ₹31.12 Cr PAT, within 3% of consolidated since the lone joint venture is a small overlay.

The margin picture is weaker than the PAT headline suggests. Operating margin (EBITDA/revenue, excluding other income) compressed to 9.07% from 10.54% a year ago and 10.04% last quarter — roughly 150bps and 97bps of give-back respectively — as cost of materials and other expenses grew faster than the 41% revenue jump, consistent with raw-material pressure not being fully passed through despite strong volumes. Net margin nonetheless rose to 3.89% from 3.16% YoY, but that expansion is not operating in nature: it is driven by the tax-rate cut (115BAA adoption dropped the effective rate to 25.1% from 36.2%) and a one-off-looking other income spike to ₹5.26 Cr (versus ₹0.18 Cr in Q1 FY27 and ₹1.04 Cr a year ago, unexplained in the filing). Adjusting PAT for the tax-rate effect alone brings YoY growth down to roughly +48% (closer to the ₹12.5 Cr increase in consolidated PBT, +47.8% YoY); stripping the other-income jump as well brings core pretax growth to around +32% — still trailing the 41% revenue gain, confirming margin compression, not tax, is the real operating story this quarter.

The stock went into the print at ₹132.23, up 3.1% over the past month of trading.

For context: this is the second-highest quarterly PAT of the last 6 quarters; revenue is at a 6-quarter high.

We have no prior management guidance or concall commentary on record for this company, and a web search turned up no brokerage previews or consensus estimates for Q2 FY27 — JBML carries no visible formal street coverage, so vsGuidance and vsStreet are both unknown rather than inferred. The filing itself is a standard exchange letter with no MD&A-style commentary from management explaining the other-income line or the margin trend. Alongside the results, the board also approved a leadership reshuffle — Mayank Varma redesignated CEO over both the tooling and auto-components businesses, Deepak Gupta moved to Strategy & Diversification, and a new Company Secretary appointed effective December 18, 2026 — corporate developments concurrent with, but not tied to, this quarter's numbers.
