Bottom line
The sleeper story is a 6-9 month delay in monetizing $350M of capacity investments, with revenue impact pushed to Q3/Q4 2025 while depreciation hits immediately. Yes, infrastructure doubled and they're winning in silicon photonics, but the binding constraint is customer qualification cycles, not demand or capacity. Management admitted 'added capacities are in various stages of customer qualification with expected shipments in Q3 and Q4,' a timeline regression from prior quarters. Most revealing quote: 'I don't have at this point strong visibility in the specific POs that we'll be receiving.' My view changes if Q2 shows acceleration without waiting for H2, proving qualifications are ahead of their sandbagged timeline.

The 30-second version

  • SiPho/SiGe capacity investments are hitting qualification walls, pushing revenue impact to Q3/Q4 2025
  • Infrastructure growth story intact but Android weakness creating a $75M headwind
  • Agrate depreciation is crushing margins while contributing zero revenue
