Cummins India — steady diesel, lumpy data centers

The State of Play

Cummins India finished FY26 with sales of ₹11,950 crore, up 18%, and profit before tax up 24% — comfortably clearing the “double-digit growth” guidance management repeated, without once tightening it, on all four calls. The year’s texture came from one customer category: data centers, now 30–35% of domestic power-generation revenue, whose lumpy hyperscaler orders swung the powergen segment from +49% in one quarter to −16% in the next and back to +48% in the fourth. For FY27, the language shifted from February’s “we will target double-digit growth” in the domestic business to May’s carefully unquantified “moderate growth across segments” — the closest thing to a tell in a year of otherwise unflappable communication.

The Company

The Indian arm of Cummins Inc. (a rock-steady 51% parent since forever), Cummins India makes diesel and alternative-fuel engines from 2.8 to 100 litres and gensets up to 3,000 kW, sold through four lines: domestic power generation (backup gensets — the segment data centers live in), industrial (rail, construction, mining, marine, compressors), distribution (the aftermarket/service annuity, now ~31% of sales in its best quarter), and exports (high- and low-horsepower gensets to Europe, Middle East, Africa, Latin America). The regulatory backdrop matters: India’s CPCB IV+ emission norms (July 2023) forced a ~30–35% price increase and a technology upgrade that favours branded players — and created a coming aftermarket annuity as those electronically controlled gensets exit their two-year warranties from June 2026.

The financial picture is the cleanest in this batch: essentially debt-free (₹37 crore of borrowings against ₹8,420 crore of reserves), ROCE of 39.5%, a 77% dividend payout, and free cash flow of ~₹1,487 crore. The decade’s shape mirrors the sector: stagnant FY15–FY21 (sales stuck near ₹5,000 crore), then a near-tripling to ₹12,143 crore by FY26 as margins re-rated from 14% to ~21%. FIIs have built from 14% to 21% while DIIs trimmed. The price of quality: 66x earnings and ~19x book, with working-capital days drifting from 64 to 99.

The Story So Far

Q1 FY26 (call: August 8, 2025) — broad-based, no asterisks

Sales rose 26% to ₹2,859 crore with PBT up 32%, and MD Shveta Arya’s framing was deliberately unexciting: powergen’s 31% growth was “core G-Drive growth,” no one-off project orders, spread across quick commerce, government infrastructure, manufacturing and pharma. Data centers sat at 15–20% of overall powergen — steady, “from all different kinds of data center players.” CPCB IV+ had reached ~60% of domestic powergen, with market volumes finally back to pre-transition levels. The guidance, which would not move all year: “double-digit growth in the full year” — and when pushed for a range, “it is difficult to give you a range.” Exports (+34%) were credited to focused positioning, not market recovery, and kept officially “cautious.” Capacity utilisation: 65–70%, with no big capex needed.

Q2 FY26 (call: November 7, 2025) — the hyperscaler quarter, pre-labelled a one-off

Sales jumped 28% to ₹3,122 crore, PBT up 41% — and management immediately discounted its own best segment. Powergen’s 49% growth was driven by data centers at ~40% of segment revenue that quarter, which Arya characterised as “a little lumpy projects business, great execution in this quarter, which will not come through” in H2. Ex-data-center, powergen grew 20%. Industrial fell 5% — an extended monsoon stalling construction, and Coal India having issued no major new equipment tenders “for 2 years.” Exports hit a near-three-year high but were flagged to soften on channel inventory correction. Both warnings proved accurate. Competitive intensity got its strongest language of the year — rising “every month, every quarter,” especially in low- and medium-horsepower — answered with the value-proposition argument: “a backup genset is used as an insurance… It has to work on that particular day.”

Q3 FY26 (call: February 5, 2026) — the predicted air pocket, cushioned by the annuity

Exactly as pre-announced, sales dipped 1% YoY to ₹3,006 crore as powergen fell 16% on data-center timing (core powergen still grew “very close to double digits”). The cushions: distribution posted an all-time high ₹939 crore, up 26% — the installed-base annuity compounding — and gross margin hit ~38%, a 20-quarter high, which management took pains to decompose honestly: durable supplier cost work, plus one-time supplier benefits and favourable mix that were “not repeatable.” A ~₹50 crore one-time management-cost true-up dented reported PBT. The forward markers: “for financial year ‘27, we will target double-digit growth” (domestic), data centers positive “for the next 3 to 4 years,” and the CPCB IV+ out-of-warranty service uplift pencilled for “‘27 onwards.”

Q4 FY26 (call: May 29, 2026) — a strong close and a softer adjective

The March quarter delivered sales of ₹2,963 crore (+23%) with domestic powergen up 48% — data centers at ~35% of the segment, hyperscaler revenue alone ~₹250 crore. The full year closed at ₹11,950 crore (+18%), powergen +24%, distribution +22%, industrial −1% (the year’s one flat tyre: construction at half its prior pace, compressors in down-cycle, mining only just reviving), exports +12%. The India data-center thesis got its most concrete articulation: installed base headed “from 1.5 gigawatts to 6 to 10 gigawatt,” inquiry velocity up sharply since October, colo demand visible three years out, and the market staying on the fully localised QSK60 engine “for the next 2 years” — Cummins’ cost moat — before larger imported engines (78L more likely than 95L) enter, where competitors like Perkins, Baudouin and Adani also play. The parent’s $450 million build-out to 20 GW of genset capacity by 2030 should shorten India’s import lead times.

And then the guidance: “moderate growth across segments” for FY27 — explicitly not quantified despite multiple attempts, justified by robust current demand running into rising commodity prices, supplier labour shortages, and war-related logistics. Against February’s “we will target double-digit growth,” the May phrasing reads as a deliberate half-step back — caution about cost inflation more than demand, on management’s own telling, but a change in language all the same.

The ledger: said vs. delivered

Kept: double-digit FY26 growth (delivered +18%, never re-guided in either direction); the Q2 warnings — H2 data-center moderation and Q3/Q4 export softness — which played out almost to the quarter; “maintain or expand margins” (gross margin ended at a 20-quarter high, with the non-repeatable portion flagged in advance); pricing held with “no domestic pricing action” through the year. Honest accounting: the ₹50 crore true-up and the one-time margin components were volunteered, not extracted. Persistent soft spots: industrial (guided hopefully each quarter, finished −1%); BESS, launched with fanfare in mid-2025, still had “a lot of inquiries, very slow sales” four quarters later, with no revenue target management would touch. The wrinkle: FY27’s “double-digit domestic target” (February) becoming “moderate growth” (May) — the only quarter-to-quarter softening of language in an otherwise metronomic year.

Where Things Stand

Cummins enters FY27 with robust order books by its own account, ~70% utilisation, no major capex needs, and three structural levers: the India data-center build-out (where its localised QSK60 dominates the current node, and the question is what happens when sites scale to imported-engine sizes), the CPCB IV+ aftermarket annuity beginning as warranties expire from June 2026, and a distribution business management expects to keep compounding above 20%. Offsetting: commodity and supplier-cost inflation (passed through “with a lag”), an industrial segment waiting on construction and Coal India, exports nobody will forecast, and competitive intensity rising at every node. The valuation — 66x earnings for a company guiding “moderate growth” — leaves the data-center optionality doing a lot of the work.

The Four Checks

1. Quality and moat. A genuinely good business with a strong but not unassailable moat. The moat is layered: the parent’s engine technology (Cummins Inc. at a never-wavering 51%), a distribution-and-service annuity now running above ₹900 crore a quarter, the CPCB IV+ emission transition that raised the technology bar in favour of branded players, and — for the current data-center node — the fully localised QSK60 engine, a cost advantage management expects to hold “for the next 2 years.” The buyer’s logic reinforces it: a backup genset is insurance, and insurance buyers pay up for the brand that works on the day. The erosion vectors are real, though — management itself flagged competitive intensity rising “every month, every quarter” in low- and medium-horsepower, and the next data-center node (larger imported engines) is contested ground where Perkins, Baudouin and Adani also play. Strong franchise, contestable edges.

2. Returns on incremental capital and runway. The returns are excellent and improving — ROCE of 39.5% and ROE of 30.2% per the snapshot, up from roughly 17% ROCE in FY21 as margins re-rated from 11–14% to a steady ~21%. The catch is how little capital those returns get to work on: total capex was “more than ₹1,000 crore” over five years (line modernisation, not expansion), utilisation sits at 65–70%, and management says no major capex is needed for FY27. The growth runway — data centers scaling from 1.5 GW toward 6–10 GW, the CPCB IV+ aftermarket annuity starting June 2026 — is genuine, but it runs through existing capacity and the parent’s $450 million global build-out rather than Cummins India’s own balance sheet. Exceptional returns, narrow deployment.

3. Capital allocation for the stage. Close to textbook for a mature, capital-light franchise. The business can’t usefully absorb its cash flow, so it doesn’t pretend to: the dividend payout has climbed from ~50% a decade ago to 77% in FY26 against free cash flow of ~₹1,487 crore, borrowings are a token ₹37 crore against ₹8,420 crore of reserves, promoter holding has sat at exactly 51% forever (no dilution, no creep), and there are no acquisitions or adjacency adventures on the record. No buyback history is visible in the data — the cash return runs entirely through dividends, the standard route for a 51%-held MNC subsidiary. The one genuine quibble is working capital drifting from 64 to 99 days. Minor smudges on an otherwise clean sheet.

4. Price. Demanding. As of the June 2026 snapshot, the stock trades at ₹5,662 — 64.8x earnings and 18.5x book value, with a 1.2% dividend yield — for a company whose own FY27 guidance just softened from February’s “double-digit growth” to May’s unquantified “moderate growth.” The quality is real (five-year profit CAGR of 30.8%, 40% ROCE, debt-free), but at this multiple the durable genset franchise is fully paid for and then some; the data-center build-out and the post-warranty aftermarket annuity have to deliver just to justify the tag. A price that needs the optionality to show up.
