Power Integrations (POWI) has drawn fresh attention after reporting second quarter 2026 results, alongside a new PowiGaN gallium nitride platform rated at 2,200 V, aimed at high-voltage data centers, EVs and renewable-energy applications.

Bulls point to Power Integrations' GaN progress, recent earnings growth, and a dividend that remains in place. Bears see a stock that ran hard year to date before pulling back. Do current multiples still stack up on the numbers?

Most Popular Narrative: 22.1% Undervalued

Compared with the latest close at $62.31, the most widely followed narrative on Power Integrations sees fair value at $80. This view leans heavily on GaN leadership and long term earnings power.

Growing adoption of advanced power conversion technologies in EVs, AI data centers, renewable energy, and modern power grids is expected to drive long-term expansion of Power Integrations' addressable market, supporting sustained revenue growth over time.

For readers curious about what sits behind that higher fair value, the narrative focuses on a potential step change in earnings, richer margins, and a future profit multiple that would need to be maintained. The full breakdown shows how those moving parts are combined to arrive at $80.

Result: Fair Value of $80 (UNDERVALUED)

However, this Power Integrations narrative could be challenged if consumer appliance demand stays weak, or if trade and tariff pressures continue to weigh on international sales.

Another View on Power Integrations Using Market Multiples

The first narrative argues that Power Integrations is 22.1% undervalued at $80 fair value. On current numbers though, the stock trades on a P/E of 138.9x, which is much higher than the US Semiconductor industry at 54.7x, peers at 46.7x, and a fair ratio of 41.7x.

This wide gap suggests investors today are paying a steep premium relative to both sector norms and where the fair ratio indicates the P/E could trend over time. The key consideration is whether future earnings delivery will sustain that premium.
