Layer 7 · POWI — Power Integrations
Live: USD 74.99 · Earnings (last): Q1 2026 — non-GAAP EPS $0.25 beat by 11%; rev $108.3M missed top-line (but +2.6% YoY) · Next earnings: not within 60d · Conviction: 3/10
Bottleneck context
Power Integrations sells AC-DC and DC-DC controller ICs into industrial, consumer, communications and automotive end markets. The industrial segment is growing +23% YoY on renewables and battery storage, now 41% of sales. That growth is genuine but it is not directly tied to AI data center power delivery — that bottleneck flows through NVTS, VICR (Tier B) and a few specialty silicon names. POWI is best understood as an industrial-cycle name with peripheral AI mention.
Why Tier C
Limited direct AI data center exposure is the headline reason — peers NVTS and VICR are the clean expressions of the 800V power delivery thesis. Q1 missed top-line consensus (beat only on EPS), and the +2.6% YoY growth rate is not high enough to argue for re-rating. The company is a good operator with a clean balance sheet, but it is not a bottleneck name in our master frame. The C-tier flag is structural, not tactical.
Watch trigger
Disclosure of an explicit AI data center program win (e.g., NVIDIA or hyperscaler design-in).
