Short answer
Compare a half-year result with the same half of the prior year, and write the months beside each figure. Dividing a half-year number by last year’s total gives a share of that total, which is not growth, and doubling it assumes the second half repeats the first. Ask finance to confirm both periods, the source table and the calculation.
TL;DR
- →Write out the dates, metric definition and reporting scope before calculating a change.
- →Use the comparable prior half for half-year growth; label a share of last year's total as a different calculation.
- →Keep forecasts and explanations of performance separate from arithmetic.
A journalist asks whether the company is growing. The brief holds first-half revenue of 48 million rupees and last year’s full-year total of 100 million. A colleague divides one by the other and wants to call the result growth. The arithmetic is fine. It answers a question nobody asked.
Compare like with like: this year’s first half against last year’s first half, with the months written out. Do not double a half to project a year, and send finance one question that names both periods and the source table. The communications task is to choose a meaningful comparison from figures the finance owner has confirmed and cleared for the intended response. Keep the underlying source tables open, including their headings and notes. A copied number without its reporting period gives the writer too little information to describe performance. Period and scope are the first lines of a full press release fact-check, and they matter as much in a short media answer.
How do you compare half-year results with a prior year?
Compare the same months: this year’s first half against last year’s first half, with the dates written beside each figure.
Use this hypothetical company for a worked example. Revenue for January through June 2025 was 40 million rupees. Revenue for all of 2025 was 100 million rupees. Revenue for January through June 2026 was 48 million rupees. Assume the finance owner confirms that all three figures use the same revenue definition, currency and business scope.
Compare the two first halves
The increase is 8 million rupees. Dividing 8 by the earlier 40 gives 20 percent; the earlier figure is the denominator, one of the details covered in checking the denominator behind a percentage. Wording for review: Revenue for January through June 2026 was 48 million rupees, up 20 percent from the same period in 2025. The period belongs in the answer even if the question uses the shorthand this year.
Describe progress relative to the prior annual total
The current 48 million is 48 percent of the previous full year's 100 million. That is a share of a historical annual total. It does not establish a growth rate for the current year. This comparison might answer a specific question about scale, but it needs both periods stated and can distract from the comparable first-half result.
Examine a proposed annual projection
Doubling 48 produces 96 million rupees. It assumes the second half contributes the same amount as the first. The example's previous year contributed 60 million in its second half, so even the supplied history shows uneven halves. Doubling alone establishes neither a forecast nor a claim that annual revenue will fall by four percent.
Can you double a half-year figure to estimate the full year?
No. Doubling assumes the second half repeats the first, which seasonal revenue rarely does, and it makes no sense at all for a balance such as headcount at a date.
Distinguish an amount accumulated over a period from a balance at a date. Revenue over six months and employees at June 30 describe different kinds of measurement. You would not double the employee count to estimate a December workforce. Put start and end dates beside period totals and an as-of date beside point-in-time values.
Rates need their own care. Two half-year percentages cannot automatically be averaged to produce a full-year percentage. If each uses a different denominator, ask for the underlying numerator and denominator and the owner's approved calculation. Even a mathematically correct weighted result may be inappropriate when definitions or business boundaries changed.
Uneven halves are often seasonal. Official statisticians use seasonal adjustment to remove calendar-related variation tied to the time of year, which makes comparisons between consecutive periods easier1. Without that adjustment, comparing a half with the same half a year earlier keeps the seasonal pattern on both sides of the comparison.
Calendar labels also deserve a check. A company's first half might follow a financial year that starts outside January. Replace H1 with explicit months at least once in the response. Confirm whether the prior comparison was revised; an older release may contain a value that the current source has since restated. A note to the table may record a method change or restatement, so read the footnote before you rely on the comparator.
What should you ask finance before publishing a comparison?
Send one note that names both periods, the source table, the calculation and the wording you propose, and ask finance to confirm scope, definitions and any revised comparator.
A useful review note is: We propose comparing [metric] for [current dates] with [prior dates], using [source version and table]. Please confirm consistent scope and definitions, any revised comparator, and the calculation [formula]. Proposed public wording is [sentence]. Please also identify who can clear disclosure. This separates checking the calculation from permission to send it.
If an acquisition or reporting change makes the figures incompatible, request a reconciled comparison with its explanation. The problem is the one described in when the same metric covers a different scope, applied across time. Avoid building your own adjusted series from fragments. When a comparable prior half is unavailable, say which current figure can be provided and what comparison cannot yet be made. The deadline does not supply the missing denominator.
Treat explanations as additional claims. A revenue increase does not, by itself, show that customer demand caused it. Prices, business scope and other factors may need consideration by the relevant owner. Keep the arithmetic sentence intact while asking separately whether there is an approved explanation of the change.
QuoteIt records each figure with its subject, value, scope and period beside its source passage, so the months behind a number stay with it into the draft and in front of the reviewer.
Which comparison should lead the media response?
Lead with the one comparison that answers the journalist’s question, usually like period against like period, and keep the rest in the calculation sheet for the reviewer.
For the example, lead with the 20 percent first-half increase if the question concerns comparable growth. Include the annual total only if it helps answer a separate part of the inquiry. Too many mathematically valid comparisons can make the response harder to interpret and encourage a headline based on the least useful one.
The final response should give the reader one comparison and give the reviewer its period, calculation and source. Phrases such as up, ahead, on course and accelerating belong in the calculation sheet; any phrase without a comparable period or approved forecast needs a question, qualification or edit.
Can you compare H1 revenue with last year’s full-year revenue?
You can state the share, for example that the first half reached 48 percent of last year’s total. It is not a growth rate, and calling it one misleads the reader.
What does H1 mean in a press release?
The first half of the company’s financial year, which may not be January to June. Write out the months at least once so the reader knows which period you mean.
Should a media response use seasonally adjusted figures?
Only if finance has published or confirmed them. Otherwise compare the same months year on year, which removes most of the seasonal effect without new calculations.
Can you average two half-year percentages?
Not safely. If the two rates use different denominators, the average is wrong, so ask finance for the underlying numbers or their full-year figure.
Where can you find a comparable prior period?
Usually in the company’s own interim report. SEC rules for US filers and IAS 34 under IFRS both expect interim reports to include comparative prior-period figures.
