There is no defensible winner from scale alone. UltraTech is much larger on the available FY26 figures, but deciding which stock is better requires a like-for-like review of growth, margins, leverage, cash flow, capacity returns and valuation on the same date. JK Cement and UltraTech must be compared using consolidated statements, the same financial period and clearly defined ratios.

The latest evidence available for this comparison covers the year ended 31 March 2026. JK Cement’s consolidated audited filing was approved on 23 May 2026, while UltraTech reported its FY26 results on 27 April 2026. The figures are company-reported and should be treated as a starting point for analysis, not as a valuation verdict.

What the available FY26 numbers actually show

The reported figures establish a large difference in operating scale, but they do not establish which share is cheaper or likely to produce the better return. UltraTech’s reported sales and operating profit are presented under its own reporting definitions; JK Cement’s revenue figure comes from its audited consolidated filing. A comparison must therefore preserve the labels rather than silently treating every line as interchangeable.

Metric JK Cement UltraTech Cement Basis and qualification
Consolidated revenue or net sales ₹13,722.30 crore revenue from operations ₹87,384 crore net sales FY26; JK figure from the audited consolidated filing for the year ended 31 March 2026; UltraTech figure from its FY26 results
Operating-profit measure Not stated in the cited FY26 filing summary (JK Cement audited filing, approved 23 May 2026) ₹17,598 crore PBIDT FY26; PBIDT is UltraTech’s reported measure and should not automatically be relabeled EBITDA
Profit after tax Not stated in the cited FY26 filing summary (JK Cement audited filing, approved 23 May 2026) ₹8,305 crore PAT before exceptional items FY26; UltraTech figure excludes exceptional items
Net debt to EBITDA Not stated in the cited FY26 filing summary (JK Cement audited filing, approved 23 May 2026) 0.94x at 31 March 2026 Company-reported ratio; the definition must be matched with JK Cement’s measure before making a relative claim
Domestic grey-cement capacity Not stated in the cited FY26 filing summary (JK Cement audited filing, approved 23 May 2026) 200.1 MTPA after 8.7 MTPA was commissioned in April 2026 The commissioning occurred after the 31 March 2026 FY26 year-end, so it is not an FY26 year-end capacity figure

UltraTech’s reported domestic grey-cement capacity is a post-year-end update, not evidence that the full addition contributed to FY26 earnings. Likewise, the difference between JK Cement’s revenue from operations and UltraTech’s net sales should not be converted directly into a margin or market-share conclusion without reconciling accounting presentation and business scope.

Start with a like-for-like comparison

Use consolidated statements for both companies

Consolidated accounts include subsidiaries and other controlled operations. Comparing one company’s standalone accounts with the other’s consolidated accounts can distort revenue, debt, profit and cash flow. Download the same type of statement for both businesses, record the reporting date, and keep the treatment of exceptional items consistent.

Freeze the period before collecting ratios

Use FY26 for both companies, or use the same quarter for both. Do not combine JK Cement’s audited year-end numbers with a later UltraTech capacity update and describe the result as a single-year comparison. A post-year-end event can be relevant to future earnings, but it belongs in a forward-looking section.

Keep accounting labels intact

PBIDT, EBITDA, operating profit and profit before exceptional items can differ because companies classify income, expenses, depreciation, finance costs and exceptional items differently. Copy the reported label, then reconcile the components if you need a common ratio. If reconciliation is not possible, present the measures side by side and explain the limitation.

Measure growth before judging quality

Revenue growth

Collect at least the current and prior-period consolidated revenue or net-sales figures from each company. Calculate:

Revenue growth (%) = (current-period revenue − prior-period revenue) ÷ prior-period revenue × 100

Then split the change into volume, realization and portfolio effects where the companies disclose enough information. Cement revenue can rise because dispatches increase, selling prices improve, premium products gain share, or an acquired business is consolidated. A higher headline growth rate is not automatically better if it comes with weak pricing, lower utilization or expensive capacity.

Volume and realization

Look for cement and clinker volumes, regional dispatches and average realization per tonne. Use the same denominator for both businesses: cement volume should not be compared with a figure that also includes clinker or other building materials unless the companies define the aggregates identically. If one company reports blended realization and the other reports cement-only realization, label the mismatch instead of forcing a calculation.

Organic growth versus acquired growth

Separate growth from existing plants from growth added through acquisitions or newly consolidated subsidiaries. Acquired revenue may increase immediately, while integration costs, maintenance capex and working-capital needs arrive over time. The useful question is whether the acquired assets improve return on capital and cash generation after integration, not merely whether they increase reported sales.

Compare profitability on a common basis

Operating margin

Calculate an operating margin only after confirming that the numerator and denominator match:

Rank #2

Operating margin (%) = operating-profit measure ÷ revenue or net sales × 100

UltraTech’s PBIDT should remain identified as PBIDT unless its report provides a reconciliation to EBITDA. For JK Cement, obtain the corresponding consolidated operating-profit line from the audited filing. Do not infer JK Cement’s margin from revenue alone.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Profit after tax and exceptional items

Use underlying PAT for recurring profitability and show exceptional items separately. UltraTech’s FY26 figure in the available results is PAT before exceptional items. If JK Cement’s reported PAT includes exceptional gains or losses, adjust only with a documented reconciliation. A one-time gain can make a low-quality year look strong; a one-time charge can make a sound operating year look weak.

Cost drivers

For each company, examine energy, fuel, power, freight, raw materials, employee costs and other operating expenses as a percentage of sales. Cement margins are sensitive to petcoke or coal prices, electricity costs and transport distance. A margin advantage is more durable when it comes from structural access to efficient plants, captive power, logistics or premium products rather than a temporary input-cost movement.

Per-tonne economics

Where both companies disclose comparable volumes and costs, calculate revenue, cash cost and operating profit per tonne. State whether the denominator is cement only, cement plus clinker, domestic only or consolidated. Per-tonne figures are useful for comparing efficiency, but they can mislead when product mix, geography and freight intensity differ materially.

Check the balance sheet and cash conversion

Debt and leverage

Collect gross debt, cash and equivalents, lease liabilities where relevant, net debt and the exact EBITDA definition used in each ratio. UltraTech reports net debt-to-EBITDA of 0.94x at 31 March 2026. That is a company-reported figure; it becomes informative against JK Cement only after obtaining JK Cement’s matching numerator, denominator and date.

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Use:

Net debt = gross borrowings − cash and cash equivalents

Net debt-to-EBITDA = net debt ÷ EBITDA

Check whether the company includes leases, restricted cash, perpetual instruments or acquired-business adjustments. Two ratios with the same name can still measure different liabilities or earnings.

Interest and debt-service coverage

JK Cement’s FY26 filing includes debt-service and interest-service coverage ratios, but the available summary does not provide their values. Retrieve the exact figures and definitions before comparing them with UltraTech or with a lender’s covenant thresholds. In general:

Interest coverage = earnings available for interest ÷ interest expense

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Debt-service coverage = cash available for debt service ÷ scheduled principal and interest payments

Coverage can deteriorate even when EBITDA grows if borrowing rises faster, rates increase or cash is tied up in working capital.

Operating cash flow and free cash flow

Profit does not equal cash. Compare cash flow from operations, capital expenditure, changes in working capital and free cash flow over several years. A useful approximation is:

Free cash flow = cash flow from operations − capital expenditure

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

Read the cash-flow statement with the notes: a large working-capital release can temporarily lift cash, while advance payments, inventory build-up or acquisition payments can suppress it. Also separate maintenance capex from expansion capex when the disclosures permit.

Assess capacity, utilization and execution

Capacity is an option, not a return

New capacity creates value only when demand, pricing, utilization and returns justify the investment. Compare installed capacity, effective capacity, utilization, commissioning dates, project cost, expected ramp-up and the market each plant serves. A plant running below economic utilization can dilute returns even if it increases tonnes sold.

UltraTech’s April 2026 addition

UltraTech reported domestic grey-cement manufacturing capacity of 200.1 MTPA after commissioning 8.7 MTPA in April 2026. Because that commissioning followed the 31 March 2026 year-end, treat it as a future-period growth and execution variable rather than FY26 production capacity. The analysis should ask how quickly the new assets ramp, what capex remains, and whether local demand can absorb the additional supply without damaging realization.

JK Cement’s project review

For JK Cement, collect the same project-level information from its filings: capacity by region and product, commissioning schedule, utilization, expansion spending and funding source. Do not infer comparative capacity from the revenue figures. A smaller company can still create shareholder value through high utilization or attractive regional pricing, while a larger company can destroy value through overbuilding or poor integration.

Geography and product mix

Map each company’s exposure to grey cement, white cement, wall products and other building materials, along with the states or regions served. Regional supply-demand balances, freight distances and dealer networks often matter more than national averages. Premium products may support realization, but they also require separate volume and margin evidence.

Value the shares on one timestamp

The available figures do not establish a current share-price comparison, so they cannot support a claim that either stock is cheap or expensive. Build the valuation snapshot only after recording the same market date and time zone for both securities.

Minimum valuation dataset

  • Closing share price on the same date.
  • Shares outstanding and market capitalization on that date.
  • Net debt measured on the latest comparable balance-sheet date.
  • Trailing twelve-month revenue, EBITDA or the consistently defined operating measure, and PAT.
  • Forward earnings or EBITDA estimates, with the forecast provider and publication date.
  • Dividend per share and dividend yield, identifying whether the dividend is declared, proposed or paid.

Core multiples

Calculate:

Trailing P/E = market capitalization ÷ trailing PAT

Forward P/E = market capitalization ÷ forecast PAT

Special offer. See more information about Outbyte and uninstall instructions. Please review EULA and Privacy policy.

EV/EBITDA = (market capitalization + net debt) ÷ EBITDA

Dividend yield (%) = annual dividend per share ÷ share price × 100

Use the same earnings basis in both numerators and denominators. Do not compare UltraTech’s PAT before exceptional items with JK Cement’s reported PAT if one includes material exceptional items. For EV/EBITDA, match the EBITDA definition and balance-sheet date. Forward multiples are estimates, not facts; show the forecast source and date beside every figure.

Interpret multiples in context

A premium multiple may reflect stronger balance-sheet capacity, better geographic diversification, higher expected utilization or more reliable cash generation. A lower multiple may reflect leverage, project risk, weak regional pricing or simply a temporary earnings trough. Compare the multiple with growth, return on capital, free cash flow and downside scenarios rather than treating P/E as a standalone verdict.

Build a risk checklist

  • Demand and pricing: Cement demand and realizations are cyclical. Test a scenario with lower volume, weaker prices or both.
  • Energy and freight: Fuel, power and logistics costs can compress margins quickly. Review sensitivity disclosures and plant locations.
  • Regional supply: New plants or competitor expansions can pressure utilization and prices in a specific market even when national demand grows.
  • Execution: Delayed commissioning, cost overruns and slower ramp-up reduce returns on expansion capital.
  • Acquisition integration: Check whether acquired operations deliver the promised synergies and whether integration requires additional spending.
  • Financing: Rising debt, refinancing needs or higher interest rates can weaken coverage and free cash flow.
  • Accounting comparability: Exceptional items, leases, minority interests and company-specific operating measures can make apparently similar ratios incomparable.

Turn each risk into a measurable test. For example, model a lower utilization rate, a higher freight cost per tonne, delayed capacity ramp-up or a higher borrowing rate, then observe the effect on cash flow, leverage and interest coverage.

A practical worksheet for the comparison

  1. Set the date: choose FY26 or an identical quarter and write the period-end date at the top of the worksheet.
  2. Collect consolidated statements: download the income statement, balance sheet, cash-flow statement and notes for both companies.
  3. Normalize labels: map revenue, operating profit, EBITDA or PBIDT, PAT, debt and cash while preserving each company’s original definition.
  4. Calculate growth: record revenue, volume, realization and product-mix changes against the prior period.
  5. Calculate margins: use matching operating measures and separate exceptional items.
  6. Test cash generation: compare operating cash flow, maintenance capex, expansion capex and free cash flow.
  7. Reconcile leverage: document what each company includes in net debt and EBITDA before comparing ratios.
  8. Review capacity: list every addition, commissioning date, utilization rate, expected ramp and funding requirement.
  9. Capture market data: record both share prices, market capitalizations and valuation multiples on the same timestamp.
  10. Run scenarios: stress demand, realization, input costs, utilization, capex and interest rates.
  11. Write the conclusion: state which business has the stronger operating or financial profile, which valuation assumptions drive the result, and what evidence would change your view.

Common mistakes to avoid

Calling scale a stock recommendation

UltraTech’s larger reported base demonstrates scale, not automatic shareholder returns. A large company can offer diversification and financing advantages, but the purchase price and future returns still matter.

Mixing dates

Do not place an April 2026 capacity commissioning in an FY26 year-end table without labeling it as post-year-end. Likewise, do not pair a current share price with an old earnings denominator without dating the mismatch.

Equating PBIDT with EBITDA

Use the company’s label until the components are reconciled. A superficial relabeling can change the apparent margin and EV/EBITDA multiple.

Ignoring exceptional items

Underlying earnings and reported PAT answer different questions. Show both where available and explain the adjustment.

Using unmatched leverage ratios

Net debt-to-EBITDA, interest coverage and debt-service coverage are definition-sensitive. Compare dates, inclusions and calculation formulas, not just the displayed multiple.

Filling missing data with assumptions

If a required JK Cement margin, PAT, leverage measure or capacity figure is not in the statement you are using, retrieve it from the filing or mark it as unavailable. Do not estimate it from revenue, market size or a competitor’s ratio.

How to reach a defensible conclusion

Separate the conclusion into three judgments. First, identify the stronger operating profile using comparable growth, realization, margins, utilization and product mix. Second, identify the stronger financial profile using leverage, coverage and cash conversion under the same definitions. Third, decide whether the market price compensates for those qualities using a timestamped valuation set and explicit assumptions.

On the evidence currently summarized, UltraTech clearly operates at a much larger reported scale and has disclosed a substantial post-year-end capacity base. The available information does not provide a matching set of JK Cement profitability, leverage, cash-flow and valuation figures, and it does not include a same-date share-price or multiple comparison. Therefore, the correct answer to “which stock is better?” remains conditional: complete the like-for-like operating and valuation worksheet before choosing either share.
