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)
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
