consensus next-FY EPS
The gap between the two multiples is the consensus growth expectation: analysts' forward EPS of $6.53 implies +117.7% EPS growth vs the reported trailing $3.00.
At today's $412.39 close, each upcoming fiscal year's consensus EPS implies a different multiple — how quickly the price is "paid down" by expected earnings if the estimates hold.
| Fiscal year end | Consensus EPS | Estimate range | Analysts | Implied P/E |
|---|---|---|---|---|
| 2026-11-01 | $6.53 | $6.45 – $6.70 | 12 | 63.1x |
| 2027-11-01 | $9.65 | $7.64 – $11.41 | 12 | 42.8x |
| 2028-11-01 | $14.28 | $10.36 – $17.03 | 5 | 28.9x |
Source: FMP analyst consensus estimates, refreshed with the daily precompute. "n/m" = the consensus EPS is not positive, so a multiple is undefined. There is no forward P/E history chart here because charting one would require the estimates as they stood in the past, which we do not store — see the trailing P/E history for how the realized multiple has moved.
PE Ratio = Share Price / Diluted EPS (TTM)
The price-to-earnings ratio measures how much investors pay for each dollar of trailing earnings. A lower PE can indicate a cheaper valuation; a higher PE implies higher growth expectations.
