Snapshot

  • Ticker: GFS (Nasdaq)
  • Bucket: Compute & AI Megacaps
  • Q1 2026 position: 474,593 shares, $21,109,897 — 0.42% of 13F (#46, outside the top 20); re-entry after holding in Q4 2024
  • HQ: Malta, New York
  • What it does: Trailing-edge/specialty semiconductor foundry — power, RF, automotive and, increasingly, silicon photonics.

Business Overview

GlobalFoundries is the largest US-headquartered pure-play foundry, focused on differentiated specialty nodes rather than leading-edge logic. Full-year 2025 revenue was 888M ($965M non-IFRS); Q1 2026 profitability metrics came in at or above the high end of guidance.

The AI-relevant pivot is photonics and power. GF acquired Advanced Micro Foundry (Singapore, silicon photonics) in November 2025, and in May 2026 launched SCALE, an optical-engine platform for co-packaged optics and the first tailored to the Optical Compute Interconnect MSA. It is also acquiring MIPS for RISC-V processor IP, and in February 2026 expanded a multi-billion-dollar partnership with Renesas spanning ADAS and data center power applications. GF manufactures for the top three automotive MCU vendors globally.

Why Atreides Owns It

A small re-entry that rhymes with the fund’s core AI-connectivity book. Atreides held a 21.1M. The plausible trigger is GF’s emergence as a silicon-photonics and co-packaged-optics supply-chain node — the same optics bottleneck thesis behind the fund’s much larger Ciena, Lumentum, Coherent and Credo positions — plus data center power content (the “watts” side) via the Renesas partnership. There is also a US-manufacturing/trusted-foundry policy angle. At 0.42%, this is a tracker-sized expression, not a conviction bet.

A clean exit-and-return: out for all of 2025, back at modestly larger size in Q1 2026 — consistent with the thesis changing (photonics/CPO, AMF acquisition, SCALE) rather than a price-driven re-entry.

Risks

  • No leading edge: GF’s specialty positioning means it does not capture the highest-value AI logic wafers; growth depends on content niches.
  • Photonics optionality is early: SCALE/CPO revenue is not yet material; incumbent optics suppliers and TSMC’s own photonics roadmap are formidable.
  • Auto/industrial cyclicality: the core end markets were in a prolonged inventory correction through 2024-25.
  • Customer pricing power: long-term agreements cap downside but also upside versus commodity foundry pricing.
