Summary: Caliber Mining's business is growing rapidly on the back of Coal India contracts, but every phase of growth has come with sharply higher borrowing. Before subscribing to the IPO, understand whether its strong operating business is enough to offset the risks on its balance sheet.
Caliber Mining and Logistics generated Rs 411 crore of operating cash in FY26, its best year on record, and finished that same year Rs 366 crore deeper in debt. By the end of April 2026, borrowings had climbed further to Rs 1,631 crore, against Rs 7 crore of cash in hand at the close of FY26. This is the company now asking public investors for Rs 450 crore, at a price of 17 times earnings.
The operating business behind those numbers is a strong one. Caliber digs and hauls coal for Coal India, which outsources a growing share of its production every year. Revenue has compounded at almost 33 per cent over two years, and the order book covers close to six times FY26 revenue. The decision facing an IPO investor is whether that operating strength compensates for a balance sheet that must borrow before it can grow.
Coal mining's outsourced muscle
Caliber provides end-to-end services to help mine owners extract and transport coal and other minerals such as iron ore. It owns no mines. Mine owners, chiefly Coal India, hire it as a contractor to do the heavy work.
Coal mining services bring in 86 per cent of revenue. Caliber's excavators and bulldozers strip away the overburden, the layers of earth and rock sitting on top of a coal seam, and then extract the coal underneath. Logistics contributes about 12 per cent, covering the loading, unloading and road transport of coal and iron ore on Caliber's own trucks. The remainder comes from trading coal, loading it onto railway rakes and coordinating with the railways. At heart, this is an earth-moving business paid by the tonne.
The operating edge is real
#1 Owning the fleet keeps costs low
Anyone with capital can buy an excavator. The edge lies in running hundreds of them cheaply for years. Caliber owns 1,811 mining vehicles, excavators and trucks and leases only 100, so third-party transporters have little hold over it. It runs its own central maintenance workshop plus dedicated workshops at seven mine sites. Almost all of its work sits inside a 40 kilometre radius, which lets it shift trucks, machines and mechanics between sites as the day demands. That density shows up in cash conversion. FY26 operating cash flow came in at 2.5 times net profit, and FY25's was more than double profit too.
#2 Coal India is outsourcing more every year
More than 85 per cent of FY26 revenue came from two Coal India subsidiaries, and repeat customers have supplied close to 98 per cent of revenue in Caliber's best years. Coal India's outsourced mining is projected to climb from 63 per cent of output in FY25 to around 70 per cent by FY30, and outsourced overburden removal from 89 to 94 per cent, as it opens or expands 56 mines by FY33 in pursuit of a 1.5 billion tonne production target. Caliber is also moving into iron-ore logistics in Maharashtra and bidding for work in Odisha and Jharkhand.
#3 Six times revenue already on the books
As of 15 May 2026, Caliber's order book stood at Rs 9,551 crore, up from Rs 5,668 crore just six weeks earlier. These are definitively awarded contracts, accepted in writing, rather than tenders still in play. The caveat is that mega projects of this kind can still be delayed, rescoped or cancelled if the customer fails to secure land or environmental clearances. Even so, the demand Coal India describes is visibly landing on Caliber's books.
The balance sheet undercuts the business
#1 Half the revenue must be re-won at tender
Caliber's contracts typically run two to three years, occasionally stretching to five, with no automatic renewal. Once a contract ends, Caliber must enter a fresh tender and emerge as the lowest bidder, L-1 in industry shorthand, to keep working the very same mine. Two contracts worth a combined Rs 2,229 crore expire this year, and losing either re-bid would cut revenue sharply. Caliber has lost large contracts purely on price before. The concentration deepens the risk: contracts above Rs 1,000 crore made up 76 per cent of coal mining revenue in FY26, so close to half the top line rides on a handful of re-tenders.
#2 Capex swallows every rupee of cash
That Rs 411 crore of FY26 operating cash met a Rs 692 crore equipment bill. Even Caliber's best cash year fell Rs 281 crore short of its own capex, and the company borrowed the gap. Debt jumped from Rs 754 crore to Rs 1,120 crore during FY26, then to Rs 1,631 crore by the end of April. The group closed the year with Rs 7 crore of cash against all of it. Because each new contract requires the fleet to arrive before the revenue does, expansion keeps outrunning internal cash generation.
#3 Interest already claims over a quarter of operating profit
Finance costs hit Rs 81 crore against EBIT of Rs 292 crore in FY26, an interest cover of 3.6 times, which means interest consumes about 28 per cent of operating profit. Return on equity slipped from 33.5 to 28.8 per cent even as operating profit grew, because the capital base, swollen by borrowing, grew faster than earnings.
#4 The IPO repays loans more than it buys growth
Of the fresh Rs 400 crore, Rs 208 crore repays existing debt, Rs 167 crore buys 85 new machines in FY27, and the balance goes to general corporate purposes. The machinery figure rests on vendor quotes, not signed orders. The repayment barely dents the pile: against end-April borrowings of Rs 1,631 crore, paying down Rs 208 crore still leaves roughly Rs 1,423 crore of debt, about 27 per cent above the FY26 year-end level. The company also states plainly that every contract it wins will require fleet expansion all over again.

What you are actually buying
At 17 times FY26 earnings, the price is fair for a company compounding revenue at 33 per cent a year. An investor pays roughly what the growth has earned and gets a well-run operator at a reasonable rate. The price offers no discount, however, for the leverage: debt-to-equity of 1.7 times and rising, interest consuming 28 per cent of operating profit, and a cash balance of Rs 7 crore. Even after the IPO's debt repayment, borrowings will sit well above the FY26 year-end level, and the next contract win will demand fresh loans for fresh machines.
Our view is that this trade favours waiting over subscribing. A subscriber at the top of the band underwrites a refinancing cycle in exchange for a fair price, with the downside concentrated in the one scenario that matters: a lost re-tender or a delayed mega project arriving on a stretched balance sheet.
Caliber belongs on a watchlist. The evidence that would change the answer is specific and observable: a year in which operating cash covers capex, interest cover moving back above five times, or debt-to-equity heading toward one. An investor who waits for any of these gives up a possible listing gain and keeps capital out of the only outcome here that does lasting damage.
