Market valuation and peer comparison
According to CompaniesMarketCap, Power Integrations carries a market capitalization of USD 2.81 billion as part of a comparison of timing and power-related semiconductor names as of September 20, 2026.
In the same overview, SiTime is shown at a market capitalization of USD 18.40 billion, meaning Power Integrations' equity value is roughly 84.7 percent lower than that larger peer and highlighting the different scale position within the broader mixed-signal and power electronics landscape.
Earnings context and recent fundamentals
For investors, the most recent reporting period that matters for Power Integrations is the latest quarter within the last nine months ended June 30, 2026 or later, which typically includes revenue, net income and margin figures that frame the company’s operational momentum heading into the second half of 2026.
While the week-filtered sources available do not carry a detailed Q2 2026 earnings breakdown for Power Integrations itself, they do underscore how quarterly performance and margins in the wider power semiconductor space are central to valuation and rating discussions, as seen in analysis of peers such as Monolithic Power Systems where record revenue in Q2 2026 of USD 980.6 million and a free cash flow margin of 14.84 percent for the quarter are cited as key datapoints for investors.
Ownership flows and insider activity
A useful lens on sentiment around Power Integrations is insider trading activity, and recent Form 4 filings show that company leadership has engaged in share sales at prices in the mid-70 dollar range during summer 2026.
According to StockTitan on September 20, 2026, Power Integrations President and CEO Jennifer A. Lloyd reported selling 12,690 shares of common stock on July 22, 2026 at a price of USD 73.73 per share in a Form 4 filing, a transaction that gives investors a concrete reference point for management’s realized price level in recent months.
Stock level and trading venue
As of the most recent completed trading day in September 2026 on the Nasdaq, Power Integrations stock is changing hands at a price that implies the roughly USD 2.81 billion market capitalization cited above, placing the shares between their 52-week high and low in US dollars and leaving room for movement in either direction as new data on orders, margins and industry demand emerge.
