Earnings Analysis
The company earns $3.54 per share, or $0.89 quarterly. Net income of $8,500,000,000 less preferred dividends of $0 is divided across 2,400,000,000 shares. This is the denominator in every P/E ratio and the raw feedstock of shareholder returns.
*Computed from reported statutory profit figures; underlying or NPAT-after-significant-items EPS can differ. Diluted EPS here uses a 2% additional-share assumption as a rule of thumb — use the actual diluted share count from the company's half-year or annual report for precision. Educational tool, not investment advice.
Earnings Per Share: The Language of Stock Valuation
Earnings per share is the company's net profit after tax (NPAT) divided by the number of shares on issue — the single number that anchors nearly all of fundamental analysis. It is the denominator of the price-to-earnings ratio, the basis of earnings growth rates, and the raw feedstock behind every dividend. If a company earns $9.6 billion NPAT and has 2.8 billion shares, each share represents $3.43 of profit — that is the slice of the business you own with one share. Australian investors encounter EPS everywhere: half-year and full-year result announcements are judged by whether they 'beat' or 'miss' the consensus EPS forecast, index P/E ratios are built from the ASX 200's aggregate EPS, and the sustainability of franked dividends is measured against per-share earnings rather than total NPAT. Basic EPS counts only the shares that exist today; diluted EPS includes the additional shares that would appear if options, performance rights, and convertibles were exercised — the more conservative, honest measure. Growth in EPS over time is what ultimately drives share prices, which is why this calculator projects the five-year earnings trajectory alongside the current figure.
From Net Profit to Per-Share Earnings
The basic EPS formula subtracts any preference-share dividends from net profit after tax — because preference holders are paid before ordinary shareholders — and divides by the weighted average shares on issue: EPS = (NPAT − Preference Dividends) ÷ Shares Outstanding. For every dollar of income attributable to ordinary shareholders, each share claims an equal slice. A company with 2.8 billion shares and $9.6 billion of NPAT earns $3.43 per share. Diluted EPS uses a larger denominator: the share count that would exist after in-the-money options, performance rights, and convertible securities are converted into shares, slightly lowering the per-share figure. This calculator applies a 2% dilution assumption as a rule of thumb, but the actual diluted count appears on the company's income statement in the half-year or annual report. Finally, compounding projects the trajectory: at an 8% annual growth rate, today's $3.43 EPS becomes $5.04 within five years. That projected EPS — multiplied by whatever P/E the market is willing to pay — is the essence of long-term share returns.
Expert Insights
EPS Growth Is the Engine; P/E Is the Weather
Over long periods, a share's total return approximates EPS growth plus dividends plus the change in the multiple investors pay for those earnings. Of these, EPS growth is the only fully controllable driver that compounds year after year. Companies that grow EPS 8–12% annually with stable franked payouts have historically returned roughly that same rate to patient shareholders, regardless of short-term price swings.
Buybacks Quietly Boost Per-Share Earnings
When a company buys back shares, net profit is spread across fewer shares, raising EPS even without any business improvement. This 'denominator effect' can mask stagnant operations. When analysing EPS growth, confirm whether it came from higher NPAT or from a reduced share count — growth driven purely by buybacks is less durable than organic earnings growth.
Statutory vs. Underlying EPS Can Tell Different Stories
Australian companies frequently report 'underlying' or 'NPAT before significant items' EPS that excludes impairments, restructuring, and other one-offs, while the AASB (IFRS) statutory figure includes them. The gap can run to double digits at major banks and miners in any given year. Always compute the ratio with statutory numbers first, then understand the exclusions — persistent 'one-off' charges that recur every year are effectively permanent costs.
Actionable Tips
- 1
Track Two Half-Years in a Row Before Drawing Conclusions
A single strong half-year can be noise; two full years of EPS growth is a trend. Pull the trailing twelve months from announcements rather than relying on a single half. Sudden reversals after long streaks often precede the largest share-price reactions, positive or negative.

Compare EPS Growth Across Peers, Not Against the Market
A 6% EPS growth rate looks poor against a hot index but may lead its sector. Rank the target's per-share earnings growth against its direct competitors over the same three to five years. The stock with both the highest and most consistent growth in its group is the one the market tends to reward with multiple expansion.

Watch the Share Count Dilution
Employee performance rights and capital raises at ASX-listed growth companies can add 2–4% to the share count annually, an invisible tax on your EPS claim. Check the annual report's diluted share count trend. Companies that offset dilution with buybacks preserve per-share value; those that consistently issue net new shares dilute it away.
Real-World Examples
Sandra Measured the Compounding Engine
Sandra evaluated a consumer company earning $2.10 per share and growing 9% a year. Using this calculator she projected $3.23 EPS within five years. Even if the market paid only an 18× multiple at that point, the share would be worth $58 — up from her $45 purchase price. She bought, and the math played out almost exactly as projected when the stock hit $59 in year five.
Ken Caught the Dilution Trap
An ASX tech stock Ken followed showed NPAT rising 12% annually, but diluted EPS grew only 4% because the company was issuing performance rights to employees faster than it could buy the shares back. His calculator exposed the gap. He passed, and the stock stagnated for three years while the 'growth' was spread thinner each year.
Rita Compared a Bank Payout Decision
Rita held a bank with a 70% payout ratio and wondered if the franked dividend was sustainable. She computed EPS at $3.20 against a $2.24 dividend — a 70% payout, but with bad-debt provisions rising. She used the calculator to model EPS falling 20%, which would push the payout to about 88%. She trimmed the position before an actual provision-driven EPS miss, preserving capital.
Glossary of Terms
- Earnings Per Share (EPS)
- Net profit after tax minus preference dividends, divided by shares on issue. The profit attributable to each ordinary share — the basis of the P/E ratio.
- Diluted EPS
- EPS calculated using a larger share count that assumes option, performance-right and convertible holdings have been converted to ordinary shares. The more conservative measure.
- Trailing Twelve Months (TTM)
- The sum of the two most recent half-year results, giving a current full-year EPS figure without waiting for the annual report.
