GMDC Q1: revenue up 24% YoY but consolidated PAT flat at ₹163 Cr on cost-led margin squeeze

GMDC's Q1 FY27 (quarter ended 30 June 2026) is a strong-topline, flat-bottomline print: consolidated revenue from operations rose 23.8% YoY to ₹906.64 Cr, but consolidated PAT was essentially unchanged at ₹163.43 Cr versus ₹163.77 Cr a year ago (-0.2%). The entire growth in the top line was absorbed by cost inflation — net profit before tax edged up just 1.3% to ₹227.25 Cr — so the quarter is about margin compression, not profit growth. NPM slipped to ~18.0% from ~20.2% a year ago and operating margin fell harder (segment operating results ₹151.13 Cr on far higher revenue). There are no exceptional items on either side of the YoY comparison, so the flat print is clean and needs no adjustment.

The margin bridge sits almost entirely on the cost lines. Loading of lignite and overburden removal expense — GMDC's single largest cost — jumped ~50% YoY to ₹436.78 Cr, royalties and tax levies rose ~46% to ₹86.70 Cr, other expenses climbed ~49% to ₹144.07 Cr, depreciation rose to ₹33.33 Cr and finance costs spiked to ₹6.61 Cr from ₹0.51 Cr. A tailwind that partly offset these was the absence of the ₹79.03 Cr GST compensatory cess that burdened the year-ago quarter. At the segment level, Mining revenue grew 23% to ₹841.01 Cr with operating results up 21% to ₹208.07 Cr, but Power swung to a ₹6.00 Cr operating loss from a ₹10.59 Cr profit a year earlier even as its revenue more than doubled to ₹111.25 Cr — the power segment is the drag on group profitability.

The stock went into the print at ₹562, down 7.7% over the past month of trading.

For context: revenue is at a 6-quarter high.

Margins compressed — NPM ~18.0% vs ~20.2% YoY; PBT up only 1.3% to ₹227.25 Cr despite 24% higher sales

Sequentially the picture looks weaker (PAT -15.8% QoQ from ₹194.09 Cr), but that base was flattered by a ₹30.02 Cr exceptional gain booked in Q4 FY26; stripping it out, the underlying sequential dip is modest and revenue actually rose 11.4% QoQ. Management provides no formal guidance and no prior concall outlook is on record, and no Street consensus for this specific quarter could be sourced (brokerages were Neutral into the print — JM Financial ₹395, Kotak ₹362), so the result cannot be graded beat/miss against a number. Alongside the results the Board approved two strategic MoUs — with GNFC on coal-to-chemicals/underground coal gasification and with IREL (India) on rare earth elements — extending the Cambridge rare-earth-observatory tie-up flagged in June; these are optionality, not yet earnings. The read into next quarter: topline momentum is intact, but the profit trajectory hinges on whether overburden-removal and royalty costs normalise and whether the Power segment returns to profit.
