800G / 1.6T Optical Transceivers
$157.55
May 2026 · IO entry $29.05 (Oct 2025, +442%) · Mkt Cap ~$12.6B
Q1 FY26: $151.1M (+51% YoY) · FY26 guide >$1.1B (+140%)
◆ WATCH — GATE: Q2 PRINT AUG 6
Entry zone: $120–140 (post-Q2 validation)
⚠ INSIDER SELLING: $29.6M sold in 90 days. Stock +1,027% in 52 weeks. IO Fund's edge is their $29.05 cost basis — new entrants at $157 do not share that margin of safety. Q2 print (Aug 6) must validate the H2 2026 Texas fab ramp before any new entry is justified.
First company to ship 800G optical transceivers to hyperscalers in volume. FY26 revenue guide >$1.1B (+140% YoY). Capacity ramping from 100K units/month (Q1 exit) to 650K+ by end-2026. IO Fund's Oct 2025 entry at $29.05 gives them a 442% gain. The thesis is real; the execution risk is extreme. For new entry: wait for Q2 (Aug 6) to validate the ramp.

Valuation vs Growth
B
Not P/E valued (loss-making GAAP). EV/Sales ~11× on FY26 guide — expensive but pricing in a real ramp. 800G and 1.6T demand inflection is the catalyst. Q1 revenue slightly missed consensus ($151.1M vs $154.8M est). The 1,027% 52-week move means timing matters enormously for new entry.
Pre-profitability premium. IO Fund's $29 cost basis is the margin of safety — not available to new entrants at $157.
Fundamentals vs Hype
B+
First 800G volume shipment to a hyperscaler is confirmed and real. Data centre revenue +154% YoY. Monthly revenue target by mid-2027: $471M. But Q2 2026 is guided as the first non-GAAP profitable quarter — execution of the Texas fab ramp to 650K units/month is entirely unproven at scale. Single hyperscaler = majority of 800G volume = concentrated execution risk.
Partially grounded — real demand, unproven H2 2026 execution.
Institutional vs Retail
C
IO Fund was early (Oct 2025 at $29.05) — a genuine discovery trade. Current price $157 is retail/momentum-driven after +1,027% in 52 weeks. Insider selling consistent and notable ($29.6M in 90 days). New entrants at $157 are buying what IO Fund's early subscribers bought at $29. That's a fundamentally different risk position.
Retail momentum at current price. IO Fund's cost basis advantage is non-transferable.
Verdict
Watch — the gate is the Q2 print on August 6. For IO Fund, this is one of their best trades: $29.05 entry, 442% gain, and the thesis (800G ramp) is still unfolding. For new entry at $157 the math is entirely different: you have no cost basis advantage, single-customer concentration risk, an unproven Texas fab ramp, consistent insider selling, and a stock up 1,027% in 52 weeks. The only responsible entry is after Q2 confirms the H2 ramp is on track — and at a price that reflects that information, not the current optimism. Watch $120-140 as a post-confirmation entry zone.
Entry zone: $120–140 only after Q2 print (Aug 6) validates H2 ramp
⚠ Key Risks
  • 01Texas fab ramp execution — scaling from 100K to 650K units/month by end-2026 is the single most important and unvalidated assumption
  • 02Single hyperscaler concentration — one customer is the majority of 800G volume; any pause, qualification delay, or competitor design win collapses the H2 thesis
  • 03Q1 consensus miss ($151.1M vs $154.8M est) — execution already showed a gap; H2 ramp numbers are far more aggressive
  • 04Insider selling $29.6M in 90 days — consistent seller pattern from those with the best information on the ramp
  • 05Stock +1,027% in 52 weeks — any guidance miss on Aug 6 triggers a 30-50% drawdown from current levels; risk/reward is asymmetric against new entrants
