Should quarterly results be compared year on year or quarter on quarter?

Use both when they are meaningful. Year-on-year comparison controls for seasonal patterns; quarter-on-quarter comparison shows the latest sequential direction. Banks, retailers, commodity companies and project businesses can have different seasonality, so label the comparison clearly.

Which numbers should I check first in quarterly results?

Confirm the reporting basis and period, then examine revenue, operating profit or EBITDA, margin, attributable PAT and EPS. Next inspect working capital, debt, cash flow, segment performance, exceptional items and management guidance.

Why can profit fall when revenue grows?

Revenue can grow while input costs, employee expenses, finance costs, depreciation or tax rise faster. Product and segment mix can also change. Build a bridge from revenue to operating profit and then from operating profit to PAT rather than treating profit growth as one unexplained number.

Do strong quarterly results mean the stock should rise?

No. The share price reacts to the result relative to expectations and valuation, not simply relative to last year. Guidance, one-time items, market positioning and what was already priced in can dominate the reaction.

How to Analyse Quarterly Results in 10 Minutes

Quarterly results arrive with enough numbers to make an investor feel informed and enough noise to make the wrong number look important.

The solution is not to read faster. It is to read in the right order.

A good first pass should answer five questions:

Am I comparing the same reporting basis and a genuinely comparable period?
What drove revenue?
Did operating economics improve or weaken?
Why did profit after tax move differently from operating profit?
What changed relative to the investment thesis and valuation?

Here is a ten-minute workflow using Infosys’ consolidated quarter ended 30 June 2026 as a real example.

Minute 0 to 1: confirm the basis

Before calculating growth, write down:

company and ticker
consolidated or standalone
quarter end
reporting currency and units
filing date
source document

For the example, the company is Infosys, the numbers are consolidated, values are ₹ crore, the period ended 30 June 2026 and the XBRL result became available on 23 July 2026.

This may sound administrative. It prevents three common mistakes:

comparing consolidated results with standalone history
treating a March quarter containing year-end adjustments as identical to every other quarter
using a number before the market could have known it in a historical test

Minute 1 to 3: build the headline bridge

Do not begin with commentary. Put the latest quarter beside both the year-ago and immediately preceding quarter.

Infosys consolidated	Jun 2025	Mar 2026	Jun 2026	YoY change	QoQ change
Revenue	₹42,279 cr	₹46,402 cr	₹48,211 cr	+14.0%	+3.9%
EBITDA	₹9,943 cr	₹11,167 cr	₹11,409 cr	+14.7%	+2.2%
EBITDA margin	23.52%	24.07%	23.66%	+0.15 pp	-0.40 pp
PAT	₹6,924 cr	₹8,509 cr	₹7,775 cr	+12.3%	-8.6%

Source: Infosys consolidated XBRL filings standardized by Altys. Growth is calculated from reported values. EBITDA margin equals EBITDA divided by revenue. Figures are rounded.

One table already prevents a bad conclusion.

Against June 2025, revenue, EBITDA and PAT all grew. Against March 2026, revenue and EBITDA rose while PAT fell. Both statements are true.

The year-on-year comparison is usually more useful for a seasonal business. The sequential comparison is still useful for identifying the latest direction, as long as it is not mistaken for a seasonally adjusted trend.

Minute 3 to 4: separate growth from margin

Revenue growth tells you how much more the company sold in rupee terms. Margin tells you how much operating profit remained from each rupee.

Infosys’ EBITDA margin was 23.66% in June 2026, compared with 23.52% a year earlier and 24.07% in March 2026.

That gives a more precise reading:

year on year, revenue growth was accompanied by a small margin expansion
sequentially, revenue grew but the margin compressed by about 0.40 percentage points

The next job is to find the cause. For an IT-services business, that can include pricing, utilization, employee costs, subcontracting, currency, client mix and one-time expenses. For a manufacturer it might be volume, realizations, commodity costs, energy, freight and product mix.

Never explain a margin change with a generic phrase if the filing provides a specific bridge.

Minute 4 to 5: move from operating profit to PAT

PAT can move differently from EBITDA because it sits after:

depreciation and amortization
finance cost
other income
exceptional items
tax
minority interests

In the Infosys example, June PAT was 12.3% above the year-ago quarter but 8.6% below March even though revenue and EBITDA grew sequentially.

The table identifies the divergence. It does not establish the cause. The analyst should now inspect the below-EBITDA lines and notes rather than inventing an explanation.

This distinction is important. A good research system knows the difference between a calculated observation and a causal claim.

Minute 5 to 6: check the segments and operating driver

Consolidated revenue is an outcome. The business driver explains it.

Useful non-financial and segment measures vary by company:

IT services: constant-currency growth, large-deal value, utilization, attrition and client mix
banks: loan and deposit growth, NIM, slippages, credit cost and capital
retailers: store additions, same-store growth, sales density and inventory
automakers: volumes, product mix, realizations, discounts and capacity utilization
airlines: capacity, load factor, yield, fuel and aircraft availability
project companies: order inflow, order book, execution and working capital

Ask which operating measure would have warned you about the financial result before the financial statement arrived. That is often the right variable to monitor next quarter.

Minute 6 to 7: test earnings quality

Quarterly cash-flow statements are not always as detailed or comparable as annual disclosures, but the balance sheet still leaves clues.

Look for:

receivables growing faster than revenue
inventory growing without a clear demand explanation
payables being stretched
debt rising while profit is presented as strong
capital expenditure exceeding the cash the core business generates
large other income or exceptional gains

One quarter can be affected by timing. A repeated divergence is more significant.

For a full-year check, Altys reported FY26 cash flow from operations at 1.15 times attributable PAT for Infosys. That does not prove every quarter converted perfectly. It provides a wider-period anchor for the latest result.

Minute 7 to 8: compare management’s words with its earlier words

Do not read guidance only as a new forecast. Read it as a record of management accuracy.

Create a small table:

Question	Previous statement	Current evidence	Status
Revenue growth	What range was guided?	What was delivered and re-guided?	On track / changed
Margin	What band was expected?	What margin was reported?	On track / changed
Capital spending	What was planned?	What was spent or commissioned?	On track / delayed
Business milestone	What date was promised?	What happened?	Met / missed / unclear

The important signal is often not whether guidance rose or fell. It is whether the assumptions behind the original thesis remain credible.

Altys’ management-guidance workflow keeps the current statement attached to its history so a new promise is not evaluated in isolation.

Minute 8 to 9: ask what the price expected

A company can report good growth and still fall because the market expected more.

Before calling a result good or bad, compare it with:

published management guidance
your model
available consensus estimates, if licensed and sourced
the valuation immediately before the result
the scenario implied by that valuation

The stock price responds to the gap between outcome and expectation. Last year’s number is only one expectation anchor.

This is why “revenue grew, so why did the stock fall?” is not a contradiction. Revenue can grow while margins miss, guidance falls, working capital worsens or the valuation already discounts faster growth.

Minute 9 to 10: update the thesis, not only the spreadsheet

End the first pass with four lines:

What changed: one factual sentence.
Why it changed: the supported operating explanation, or “not yet established”.
What it changes in the model: revenue, margin, capital, cash flow or valuation assumptions.
What to monitor next: the evidence that would confirm or falsify the new view.

For the Infosys example, a factual first line could be:

June 2026 consolidated revenue rose 14.0% year on year and EBITDA margin expanded 0.15 percentage points, while sequential PAT fell 8.6% despite higher revenue.

That sentence is more useful than “strong quarter” or “mixed results” because every term can be checked.

The next sentence should come only after reading the filing, presentation and management commentary.
