Repriced or dip?
Dip: business intact
The price is 11% below its 52-week high (Jan 9), but the business held up: revenue +7.7%, revenue growth rate +3.5 pts, free cash flow +61.0%.
Some numbers held up (revenue +7.7%, revenue growth rate +3.5 pts, free cash flow +61.0%), others slipped (shares outstanding more shares, each owns less). The price is 11% below its 52-week high.
The price is 11% below its 52-week high, and the business changed too: shares outstanding more shares, each owns less.
Within 10% of its 52-week high, so there is no dip to judge yet.

Business numbers as reported at the high (12 months to Sep 30, 2025) vs the latest filing (12 months to Sep 30, 2026). Each measure is scored from −1 (business changed) to +1 (business intact) and weighted: revenue, earnings per share, free cash flow, operating margin, revenue growth rate, share count, net cash and the move vs its sector. 60 or more reads as a dip, 40 or less as a repricing.

Priced in
How much growth the market assumed at the 52-week high, the low and today (a reverse DCF).
At the high ($209.16, Jan 9) the price assumed about 46%/yr free-cash-flow growth; at the low ($91.34, Mar 12) about 27%; today about 35%. The last 3 years delivered 12%/yr (revenue).
Dashed line: what the last 3 years delivered, 12%/yr (revenue)
| High | Low | Now | |
|---|---|---|---|
| Price | $209.16Jan 9 | $91.34Mar 12 | $186.07 |
| Implied growth | +46% | +27% | +35% |
| P/FCF | 150.6× | 58.3× | 89.3× |
| EV/Sales | 17.3× | 7.7× | 15.3× |
What this means: the higher the implied growth, the more the price already counts on. If today's number sits well below what the business has delivered, the market expects less than its track record.
How it’s computed
Reverse DCF: the same 10-year free-cash-flow model as our fair value estimate (9.5% discount rate, growth for years 1–5 fading to 3% by year 10, 3% after), solved for the growth that makes it equal the market value at each price. For the high and the low we use only the filings that were public on that day, so nothing from a later report leaks back. Market value = that close × diluted shares. P/E = market value / 12-month net income; Price / FCF = market value / 12-month free cash flow; EV / Sales = (market value + debt − cash) / 12-month revenue. Hidden when the share count moved over 20% (split, merger), free cash flow is negative, or the company reports in another currency.
Valuation
What we estimate it's worth, and how it ranks on value vs every stock we cover.
Fair value estimate
How the range is computed
Ten-year free-cash-flow DCF. Same 10-year free-cash-flow model as the base: discount rate 9.5% ±1 point and growth 11.9% ±2 points. Bear = 10.5% and 9.9%; bull = 8.5% and 13.9% (both fade to 3%). A model estimate from public filings, not a forecast of where the price will go.
Price is above even the bull case.
What the price implies To be worth today’s price, PI’s free cash flow would need to grow about 35% a year for five years; our estimate uses 12%.
Risk vs market
How risk vs market is measured
One year of daily returns (Oct 31 to Nov 2, 252 sessions). Beta = how much PI moved for each 1% move in the S&P 500 (SPY); 1.0 moves with the market. Volatility is the yearly standard deviation of daily returns. Past behavior, not a forecast.
Swings much more than the market, and its own price swings are 5.3× the S&P 500’s.
