Tata Communications Ltd TATACOMM

Summary

Tata Communications is a B2B enterprise-connectivity, managed-services and cybersecurity company built on the old VSNL network backbone, not a data-center-real-estate business today. Its physical DC portfolio was sold off years ago — a 74% stake in 14 India and 3 Singapore facilities to ST Telemedia in May 2016 (deal closed 2017), with the remaining 26% Singapore stake bought out by STT GDC in June 2019. That history is now immaterial to the investment case; what remains is a residual, unconsolidated 26% minority equity stake in STT GDC India, held as an associate investment rather than a subsidiary.

Two live threads matter more. First, STT GDC India has been preparing a Mumbai IPO since at least May 2026, with reported figures moving inconsistently across sources — from an initial ~$500 million raise at a reported ~$5 billion valuation, to later reports of $800 million-$1 billion at a $6-8 billion valuation. This range is genuinely unresolved across the sources this research reached, not resolvable to one number, and should be read as a live, moving target rather than a settled figure. Second, and more operationally relevant today, Tata Communications announced an NVIDIA "AI Cloud" partnership in October 2024 — a phased Hopper-GPU rollout (2024) followed by a planned Blackwell-GPU phase (2025) for its own public-cloud infrastructure, which a March 2025 reference suggests proceeded roughly on schedule. This sits inside Tata Communications' own consolidated books, unlike the STT GDC stake, and is the more currently-real AI angle for this company, even though no GPU count or MW-scale figures could be confirmed.

The balance sheet carries real leverage: debt-to-equity of ~3.55x, against a book value of ~₹121/share supporting a rich price-to-book of ~14.82x — a valuation that plausibly already reflects some of the STT GDC and AI Cloud optionality rather than the core connectivity business alone. Profitability has been volatile and non-monotonic — PAT of ₹970cr (FY24), ₹1,837cr (FY25, though a separately-cited figure of ₹2,069.64cr for the same year could not be reconciled from sources reached), and ₹997cr (FY26) — a pattern this report states plainly rather than smoothing into a clean growth trend.

Net: HOLD. The optionality is real on both fronts, but a meaningfully leveraged balance sheet, volatile and partly-unreconciled earnings, and a rich P/B that already appears to price in some of the upside argue against a high-conviction BUY. Sell-side coverage is thin (as few as 3 brokers per Trendlyne, though one aggregator counts 11) but Buy-leaning, with targets clustering in a ₹1,900-2,600 range.

• A live, already-consolidated AI angle. The October 2024 NVIDIA AI Cloud partnership — Hopper GPUs in phase 1, Blackwell GPUs planned for phase 2 in 2025, with a March 2025 reference indicating the rollout proceeded roughly on schedule — sits inside Tata Communications' own reported business, unlike the divested DC real estate or the unconsolidated STT GDC stake.
• Real, if unresolved, value-unlock potential in the STT GDC India stake. A 26% minority holding in an entity reportedly preparing a Mumbai IPO, with cited figures ranging from ~$500m/~$5bn valuation to $800m-1bn/$6-8bn — this research treats the range as genuinely unsettled, but any outcome in that band would represent a meaningful value-recognition event against a stake whose carrying basis on Tata Communications' balance sheet was not confirmed (cost vs. fair value).
• Top-tier domestic credit quality. CRISIL AAA/Stable/A1+, reaffirmed June 2026, reflecting strong Tata Group parentage and financial flexibility even against the company's own elevated standalone leverage.
• A cleaner governance structure than some peers: Chairman (N. Ganapathy Subramaniam, Non-Executive) and MD & CEO (Ganesh Lakshminarayanan) roles are held by separate individuals, with a confirmed, five-year (FY2027-32) reappointment of Deloitte Haskins & Sells as statutory auditor.
• Buy-leaning sell-side coverage, albeit thin: ICICI Securities (Buy, ₹2,500) and Systematix (Buy, ₹2,400), with broader aggregator estimates ranging up to ₹2,600.

• A meaningfully leveraged balance sheet. Debt-to-equity of ~3.55x is high for an enterprise-services business, and ROCE (~14.6%) sitting well below ROE (~32.6%) confirms that leverage, not just operating efficiency, is doing real work in the return profile.
• Volatile, non-monotonic PAT with an unreconciled FY25 figure. PAT moved ₹970cr → ₹1,837cr → ₹997cr across FY24-FY26, and the FY25 figure itself conflicts with a separately-cited ₹2,069.64cr number this research could not reconcile — this report states the volatility directly rather than presenting a smoothed trend.
• The STT GDC India IPO numbers are a genuinely moving target, not a settled figure: reported raise size and valuation have shifted across 2026 reporting from ~$500m/~$5bn to $800m-1bn/$6-8bn, and a separate February 2026 ICRA reference to an $5.1bn, 82%-stake transaction at the STT GDC global-parent level could not be confirmed as related (or unrelated) to Tata Communications' India-specific 26% stake.
• A rich P/B (~14.82x) and trailing P/E (~48.8x, itself varying 36x-55x across providers) suggest the market may already be pricing meaningful optionality — leaving less room for multiple re-rating even if the STT GDC IPO and AI Cloud build-out both proceed well.
• No confirmed GPU-count or MW-scale figures for the AI Cloud deployment, and this research could not independently re-verify the specific NVIDIA NIM/Omniverse/Isaac integration or target-industry claims (manufacturing/healthcare/retail/BFSI) against the original October 2024 press release, which returned a 404 on the URLs attempted.
• Thin, inconsistently-counted sell-side coverage — Trendlyne cites 3 brokers, Investing.com India cites 11 analysts — a large enough discrepancy that this report treats "coverage breadth" as unresolved rather than quoting a single count.

• STT GDC India's Mumbai IPO process — the single most report-relevant catalyst; watch for an actual DRHP filing and a settled valuation, given how inconsistently current figures are reported.
• Disclosure of GPU-count/MW-scale figures for the NVIDIA AI Cloud build-out, which would allow this report to size the business rather than describe it only qualitatively.
• Reconciliation of the FY25 PAT discrepancy (₹1,837cr vs. a separately-cited ₹2,069.64cr) against the primary FY25 results filing.
• Confirmation of the Canada tax litigation resolution terms from a primary filing.

• Leverage risk (dominant). A ~3.55x debt-to-equity ratio leaves less headroom for disappointment than the credit rating alone might suggest, particularly if AI Cloud capex needs to scale.
• Earnings-volatility risk. Non-monotonic PAT and an unreconciled FY25 figure make it difficult to underwrite a clean forward earnings trend with confidence.
• STT GDC IPO-outcome risk. The currently wide range of reported valuation figures ($5-8bn) means actual IPO terms, if and when they materialise, could land meaningfully below the more optimistic figures already reflected in some sell-side commentary.
• Valuation-multiple risk. A rich P/B (~14.82x) leaves this stock more exposed than most in this report to a de-rating if either the AI Cloud or STT GDC narratives disappoint.

Tata Communications' PAT has been volatile and non-monotonic — ₹970cr (FY24), ₹1,837cr (FY25, itself unreconciled against a separately-cited ₹2,069.64cr figure), and ₹997cr (FY26) — and building EPS from PAT ÷ share count would carry that noise directly into a target price. We instead derive trailing EPS from CMP ÷ the disclosed trailing P/E (screener.in, 48.8x) against the 18 September 2026 CMP of ₹1,780, giving an implied trailing EPS of ~₹36.5. Applying a modest 8% forward-growth assumption (in line with the company's own steady ~8% revenue-CAGR characterisation, deliberately not extrapolated from the volatile PAT line) gives a constructed FY27E EPS of ~₹39.4. Given that the current trailing P/E (48.8x) and P/B (14.82x) already look rich relative to the core connectivity business — plausibly reflecting some AI Cloud/STT GDC optionality already being priced in — our base case holds the target multiple roughly flat rather than assuming further re-rating:

Base case rounded to ₹1,852, an upside of +4.0% consistent with a HOLD. Named brokerage targets found in this research (ICICI Securities ₹2,500, Systematix ₹2,400, Trendlyne consensus ₹1,903 from only 3 brokers) sit mostly above our base case; this report's more conservative stance reflects the combination of balance-sheet leverage, unreconciled earnings volatility, and the view that a meaningful share of the STT GDC/AI Cloud optionality already appears embedded in the current rich multiple, rather than any disagreement that the underlying optionality is real.

Source: screener.in (18 Sep 2026). *FY25 PAT of ₹1,837cr is screener.in's figure; a separately-cited source states ₹2,069.64cr for the same year, and this research could not reconcile the two from sources reached — flagged here explicitly rather than resolved to a single number. PAT across FY24-FY26 is volatile and non-monotonic; treat the trend with caution.
