What this means
- A range of $4.90 to $11 means the methods disagree by more than 2×. They measure different things — cash the business earns today versus growth the market expects tomorrow — so treat the range as a rough guide, not a target.
- The base case, $10, is the median of the 6 methods with data. It assumes POWER INTEGRATIONS’s current margins, cash generation and share count persist; it does not price in a new product cycle, a recession or a buyback surge.
- The number moves when the filings move. The next 10-Q replaces the oldest quarter in the trailing-twelve-month EPS and cash-flow inputs; the last one (Q2 FY2026) was filed 2026-08-06. The price changes every day; the fair value only changes with the filings.
