Establish the data before calculating
A multiple summarises a relationship between price and performance. Current market value may be paired with earnings from an older report, so record both dates. Align currency, reporting scope and share count. Trailing earnings, last-year earnings and forecasts are not interchangeable. Forecasts should be labelled and sourced separately from reported results.
Example: identical P/E, different earnings quality
Two hypothetical businesses each have TRY1 billion of market value and TRY100 million of profit, giving P/E of 10. If TRY40 million of one company’s profit comes from an asset sale, illustrative earnings excluding that gain are TRY60 million, implying about 16.67 times. That is not a correct-price verdict; it explains an adjustment. Actual tax and operating effects require separate review.
Enterprise value brings debt into view
A simplified enterprise value is equity value plus financial debt minus cash; minority interests and other adjustments may also apply. Equity value of TRY1 billion, debt of TRY400 million and cash of TRY100 million give TRY1.3 billion of EV. EBITDA of TRY200 million implies 6.5 times. EBITDA does not remove capital spending or debt-service needs; test the multiple against cash generation.
Peer selection can change the conclusion
An industry label does not make two companies comparable. Product mix, geography, growth, debt, capital needs and regulation differ. Peak-cycle profits can produce a deceptively low P/E. Negative P/E for a loss-maker should not be ranked as cheap. Price-to-book comparisons also require asset quality, accounting policy and return on equity.
How to present a multiple
Show price date, financial period, actual versus forecast status, formula, adjustments and peers together. Explain sensitivity rather than attach a buy or sell label. If earnings fall 20% while market value stays constant, P/E rises from 10 to 12.5. The example reveals how conditional the headline number is.
