Tata Comm hits record EBITDA, margin expands to 21.3%; consolidated PAT rebounds 83% YoY

Tata Communications' consolidated (primary basis) results for the quarter ended September 30, 2026 show revenue of ₹6,687.89 Cr, up 9.6% YoY and 1.6% QoQ, with consolidated PAT of ₹335.61 Cr, up 83.2% YoY (management's own parent-attributable PAT of ₹341 Cr is up 86.2% YoY). The YoY base is soft — Q2 FY26 PAT had itself fallen 27% YoY to ₹183 Cr — so part of the jump is a low-base effect, but the margin expansion underneath it is real: consolidated EBITDA of ₹1,422 Cr (+21.2% YoY) is a record for the company, with EBITDA margin up 202bps to 21.3% from 19.2%, and net profit margin up to roughly 5.0-5.1% from 3.0%. The margin bridge sits mainly in the Data Services segment (₹5,810.99 Cr revenue, the bulk of the group) and specifically the digital portfolio, which grew revenue 18.6% YoY to ₹3,016 Cr while halving its losses sequentially to a -3.6% EBITDA margin — still loss-making but moving toward the breakeven management has guided to. A ₹36.54 Cr staff-cost-optimisation exceptional charge trimmed this quarter's profit (vs a ₹21.00 Cr net exceptional expense a year ago), but adjusting for both leaves YoY PAT growth near-identical (~83.6%), confirming the improvement is operational rather than one-off driven. Standalone results tell a different story: standalone PAT fell ~40% YoY to ₹125.86 Cr (vs ₹210.94 Cr), reflecting lower other-income/un-allocable items at the parent entity rather than any deterioration in the underlying India business — readers should not read the standalone decline as contradicting the consolidated growth. On guidance, management's prior concall aim of 23-25% EBITDA margins is being approached but not yet reached (21.3% this quarter), so the direction is on-track even though the absolute target band hasn't been hit; the digital portfolio's path to breakeven is similarly progressing (losses halved QoQ) without yet crossing into profit. Our pre-result preview had flagged a profit/margin rebound as the central Street debate after Q1's profit dip, expecting gross revenue of ~₹6,800 Cr; actual revenue of ₹6,688 Cr came in slightly light of that, but the EBITDA/PAT rebound — the metric the Street was actually watching — beat the bar, with management explicitly calling this a 'stellar second quarter' and citing its 'Unified AI Stack' and DC-to-DC connectivity demand as structural growth drivers. The quarter's other context includes a ₹7,513.71 Cr contingent liability disclosed against DOT 'Show Cause-cum Demand Notices' spanning FY2005-06 to FY2024-25 (AGR-related, being contested), a separate tax appeal win for AY2011-12, two commercial paper issuances (₹550 Cr and ₹400 Cr) for working-capital/debt management, and a Company Secretary change effective November 1 — none of which affected this quarter's P&L but are part of the company's ongoing risk and funding profile. Going into Q3, the markers to watch are whether EBITDA margin keeps closing the gap to the 23-25% aim, whether the digital portfolio crosses into EBITDA profitability from its current -3.6%, and how the ₹7,513.71 Cr DOT contingent liability develops given the pending Supreme Court/TDSAT matters.
