Summary

Power efficiency plus buybacks set a 2030 path
The upside case relies on AI power becoming a durable growth leg while auto/industrial revert to mid-cycle utilization. Capital returns are a second engine, supporting per-share outcomes if cash generation holds.

Analysis

Thesis
If AI power becomes a durable “new end-market” while auto/industrial normalize, onsemi can compound into 2030 via higher power content-per-system (power stages + packaging), selective GaN expansion, and sustained buybacks that support a higher mid-cycle multiple.
Last Economy Alignment
The Last Economy’s binding constraint is watts, not ideas—onsemi sells efficiency, reliability, and secure supply for electrification and AI power conversion.

Reasoning
The setup is a mix + content story: AI data-center power and next-gen GaN widen served opportunity while auto/industrial revert toward mid-cycle utilization. With disciplined capital returns and modest multiple expansion from today’s mid-cycle valuation, the stock can plausibly deliver a low-single-digit revenue CAGR but a higher equity CAGR through re-rating plus buybacks.

Risk Assessment

Overall Risk Summary
The main risk is a “stuck mid-cycle” outcome: auto/industrial stay weak while AI power becomes price-competitive and multi-sourced. In that world, utilization, mix, and margin recovery lag, turning buybacks into financial engineering rather than true compounding.
