  • Shift: Refined ALAB's Wave-3 classification: it had been bucketed as 'foundry photonic' alongside TSEM. ALAB is fabless connectivity silicon (PCIe retimers, Scorpio scale-up fabric switches, CXL controllers), not a foundry. Its optical relevance is forward-looking — the Oct-2025 aiXscale Photonics acquisition (optical retimers for 1.6T/3.2T), a CPO bridge — not current foundry revenue.
  • Effect on thesis: Classification-only refinement; no posture change. ALAB reads as a Wave-3 connectivity-silicon momentum name positioning into Wave 4/CPO (peer to AAOI's Wave-3-to-Wave-4 bridge role), distinct from TSEM the foundry. Thesis, cohort, and HOLD posture unchanged.
  • Per-ticker: ALAB → Wave-3 connectivity silicon (PCIe/CXL retimers + Scorpio fabric), Wave-4/CPO optionality via aiXscale; NOT foundry. TSEM → remains the foundry-photonic node.
