NLC India Q2: Consol PBT -50% YoY; one-off tax credit masks an adjusted PAT decline

NLC India's consolidated Q2 FY27 revenue rose 13.3% YoY to ₹4,732.35 Cr (+0.3% QoQ from ₹4,716.75 Cr), but the headline PAT of ₹1,328.01 Cr (+83.2% YoY, +204.3% QoQ) is driven almost entirely by a one-off tax item rather than operating performance. Profit before tax (PBT) actually fell to ₹464.65 Cr — down 49.6% YoY from ₹921.34 Cr and down 28.7% QoQ from ₹651.55 Cr. The gap is explained by a ₹863.31 Cr net tax credit this quarter versus a ₹196.61 Cr charge a year ago, anchored by a ₹714.17 Cr deferred-tax remeasurement the company discloses in its notes (switch from the old to the new tax regime for the half year). Stripping that out, adjusted PAT is roughly ₹613.84 Cr, DOWN about 15.3% YoY from ₹724.80 Cr — a materially weaker underlying quarter than the reported number suggests. Operating margin compressed to 16.49% from 23.86% a year ago (and from 18.41% last quarter) as costs outran revenue: cost of fuel consumed rose 41% YoY to ₹1,163.83 Cr, and finance costs jumped 51% YoY to ₹437.57 Cr as paid-up debt capital climbed to ₹28,157.92 Cr from ₹24,327.78 Cr. Depreciation rose 33% YoY to ₹728.53 Cr on newly capitalised capacity. By segment, Thermal PBIT fell 25.8% YoY to ₹358.82 Cr and Mining PBIT fell 21.8% YoY to ₹321.87 Cr; Renewables was the only segment to grow, PBIT +13.6% YoY to ₹132.61 Cr on 24.8% revenue growth to ₹242.26 Cr — still just ~5% of total segment revenue. Management's prior concall guidance (Feb 2026) pointed to improved profitability from resolving legacy under-recoveries and lowering fuel costs via captive mines; this quarter shows the opposite on fuel costs, which rose faster than revenue, so that benefit has not yet come through. The guided IPO of renewables subsidiary NIRL, earlier targeted for September 2026, has also slipped — the board this quarter approved only an OFS structuring of up to 10 crore NIRL shares as a step toward that listing, alongside a 15% interim dividend (₹1.50/share) and approval to raise up to ₹2,500 Cr via bonds. No consensus estimates specific to this quarter turned up in available coverage, and no separate management press release accompanies this filing, so vs-street and management's own framing cannot be independently corroborated beyond the statement itself. Standalone results mirror the consolidated story (PAT ₹1,205 Cr, EPS ₹8.69, lifted by a similar ₹857.70 Cr standalone deferred-tax credit on a PBT of just ₹422.80 Cr), confirming the tax effect originates at the parent and isn't a consolidation artifact. The quarters ahead will show whether PBT recovers once this one-off rolls off, whether rising finance and depreciation costs from ongoing capex (Ghatampur expansion, renewables build-out, the pending bond raise) stabilize, and whether the captive-mines fuel-cost guidance starts showing through margins.
