GlobalFoundries (GFS)

Specialty foundry (GlobalFoundries) — RF/power/silicon-photonics, not leading-edge logic

AI exposure 11% — derived from reported segment revenue, not asserted.

Where it sits

Silicon Layer → Foundry Services · figures rebased to Q2 2026, reported 2026-08-05

Smart Mobile Devices (RF/power for phones) leads 4 businesses in this sub-tier that together are 100% of revenue, so Foundry Services is effectively the whole company rather than one leg of it.

Reported segments

Foundry services (by end-market) — 100% of revenue

GlobalFoundries (~$6.9B TTM; Q2 2026 $1.786B, +6% YoY) — specialty/mature-node foundry (NOT leading-edge; differentiated RF, silicon photonics, power, FDX). By end-market (Q2 2026): Smart Mobile ~36% (-6% YoY) + Automotive ~19% (-10% YoY) + Comms Infra & Datacenter ~16% (+62% YoY — silicon photonics for AI optical = AI-adjacent; FY26 segment guide raised to +50-60%, photonics revenue more than doubling) + IoT/Home & Industrial/PC ~29%. Primary B1 Foundry Services. Differentiated from TSMC (specialty not bleeding-edge).

How the 11% is built

Foundry services (by end-market) — 100% of revenue × 11% AI-driven (estimate). Mgmt Q2 2026: Comms Infrastructure & Datacenter was ~16% of revenue, +62% YoY, with FY2026 segment growth guidance raised to 50-60% and silicon photonics revenue more than doubling (targeting a >$1B run-rate by exit-2028); roughly two-thirds of that segment is the datacenter/optical-interconnect piece with AI linkage…

Investment read

Moat. Specialty-process moat — RF, power, FDX, automotive — deliberately outside the leading-edge race, protected by multi-year qualification cycles and $11B+ of long-term supply agreements. Post-AMF it is the largest pure-play silicon-photonics foundry, and CHIPS-funded US/EU-only capacity is itself a sourcing requirement for some customers.

Bottleneck / pricing power. Moderate pricing power via long-term agreements and requalification cost. Tellingly, the margin gain is coming from volume and mix rather than price: a record 29.9% non-IFRS gross margin in Q2 2026 (+470 bps YoY) on wafer shipments up 8%, hitting the 2026 exit-rate target roughly two quarters early, with Q3 guided to 30.5%.

Role in the AI stack. The specialty/mature-node foundry — RF, power, photonics.
