Q4 FY2026 Key Data (Feb-Apr 2026), reported 2026.06.01

Revenue $437M (+157% YoY, +7% QoQ) — Q4 alone exceeded all of FY2025. Non-GAAP GM 68.3%, OM 49.6%, EPS $1.16. Four customers each ≥10% (largest at 34%, second 27%, third 16%).
OCF record $182M; FCF $178M; ending cash $1.4B. FY2026 total revenue $1.3B (+206% YoY); non-GAAP net income $662M (5x YoY); diluted EPS $3.46 (+392% YoY). Inventory built to $251M (+$43M QoQ).
Q1 FY2027 guide: revenue $465-475M, non-GAAP GM 67-69%, non-GAAP opex $86-90M. FY2027 full year guided >80% YoY (~$2.4B) with non-GAAP net margin ~50% and >$600M optical revenue.

Key Takeaways from Earnings Call

FY2027 is an optical inflection year — >$600M optical revenue with each of three product legs >$100M individually growing >80% YoY. Bill Brennan: optical DSPs (Robin/Cardinal at 100G/200G per lane), SiPho PICs (DustPhotonics, closed last week), and ZeroFlap Optics each contribute. About half of FY2027 absolute-dollar growth comes from optical, half from copper (AECs + retimers).
AEC growth still broadening — 5 of 6 hyperscalers + neocloud expansion; ZeroFlap delivers up to 1,000x reliability over commodity laser optics. Brennan: "we're still in the early innings" of AEC penetration. Neocloud customers expected to reach ~20% of revenue. PCIe 6.0 AECs gaining design-win traction. 200G/lane (1.6T) deployments emerging — Credo "ready right now."
DustPhotonics closed last week — $750M net cash out the door in Q1 FY2027 against $1.4B Q4 cash balance; no plans to raise capital or buy back stock. SiPho PIC architecture cuts laser count, easing supply constraints; provides direct path to CPO/NPO architectures with initial revenue expected in FY2028. Tighter DSP-PIC integration deepens ZeroFlap telemetry differentiation.
FY2028 ramps: OmniConnect "Weaver" gearbox + Active Optical Cables (ALCs). Weaver enables 10x+ memory bandwidth/density for inference XPUs; Positron's 2TB LPDDR design supports $2-3K Weaver content per GPU. ALCs use microLED for 30m optical reach with AEC-class reliability.

Key Segments and Revenue Mix (FY2026)

Product Line	Revenue	% of Total	Key Details
Product Sales (AECs + ICs)	~$1.27B	~95%	AECs dominant; ZeroFlap reliability brand. Retimers (Blue Heron 200G/lane) gaining share. Optical DSPs (Robin/Cardinal) ramping.
Product Engineering Services	~$30M	~2%	Custom design services. Declining as standard product scales.
IP Licensing	~$35M	~3%	SerDes IP licensing. Steady but increasingly small share as products dominate.

Moat Assessment: NARROW

ZeroFlap reliability creates real switching costs once qualified into an AI fabric. Re-qualifying an alternative AEC across thousands of links is a months-long process; "ZeroFlap" is becoming the AI-connectivity reliability brand.
System-level integration (silicon + cable + telemetry SDK + SiPho PIC) is hard to replicate. Marvell/Broadcom sell standalone ICs; Credo sells the complete solution and now extends from copper to optical via in-house PIC.
Moat is narrow because copper is ultimately commoditizable and customers remain concentrated. BizLink is sole AEC cable maker; Broadcom/Marvell could push competing AECs; CPO could replace short-reach copper; top 3 customers still ~77% of Q4 revenue.

Stock vs. Earnings — 5-Year Performance

Stock $226 vs. ~$10 IPO (Jan 2022) — ~23x return in ~4.5 years. TTM OP went from negative (FY2024) to $639M (Q4 FY2026), one of the fastest profitability inflections in semiconductors.
Revenue scaled $87M (FY2022) → $437M (Q4 FY2026 alone) — a 5x quarterly run-rate vs. earlier full years. FY2026 totalled $1.3B (+206% YoY), more than triple FY2025; FY2027 guided >80% YoY (~$2.4B).
Non-GAAP OM expanded from low single digits to 49.6% in Q4 FY2026. Fabless operating leverage at scale; non-GAAP net margin 51.9% in Q4; non-GAAP FY2026 net income $662M (+5x YoY).

CRDO Stock Price vs TTM Operating Profit (Since 2020)

Key Drivers of Operating Profit Growth (Since IPO)

AEC adoption as the de facto standard for short-reach AI cluster connectivity. ZeroFlap delivers up to 1,000x better reliability than commodity laser optics. "Where you can use copper, use copper" — driving multi-rack deployments up to 7m.
Vertically integrated, multi-node silicon strategy keeps cost and supply favorable. 12nm AEC workhorse, 7nm optical DSPs at 100G/lane, 3nm for 200G/lane. Tight TSMC partnerships preserve capacity in tight 3nm market.
Customer diversification accelerated revenue 6x+ in two years. FY2024 had 67% revenue from a single customer; Q4 FY2026 had four 10%+ customers (top three: 34%/27%/16%) and a fourth new 10% customer not previously at that scale.

Recent Stock Performance & Drivers

Stock at $226, vs. $94 (Q4 FY2026 close) and $146 peak (Oct 2025). +141% post last quarter end on FY2027 >80% growth guide + >$600M optical revenue color + DustPhotonics close.
TTM OP scaled from $4M (Q4 FY2024) to $639M in 8 quarters. Q4 FY2026 OCF record $182M; FCF $178M. Non-GAAP net margin 51.9% in Q4 demonstrates the fabless leverage at scale.
P/E(ttm) compressed from 227x (Q4 FY2024) to 27x at Q4 close, then re-rated to 56x. Multiple expansion reflects acceleration into FY2027 (>80% growth) — not deceleration; valuation is rich but underwritten by visible optical and AEC ramps.

Opportunities

FY2027 guided to >80% YoY revenue (~$2.4B) with non-GAAP net margin ~50%. Half of absolute-dollar growth from optical, half from copper (AECs + retimers). Q1 mid-single-digit QoQ, then H2 inflection.
Optical portfolio >$600M in FY2027 with three legs each >$100M. ZeroFlap Optics, SiPho PICs (DustPhotonics), and discrete optical DSPs (Robin 100G/lane + Cardinal 200G/lane). Each leg expected to grow >80% YoY.
Neocloud customers approaching ~20% of revenue + 1.6T (200G/lane) transition is an ASP uplift cycle. Brennan flagged neocloud as a structurally growing customer base; 200G/lane ramps Robin/Cardinal DSPs + Blue Heron retimers + 200G AECs.

Challenges

Customer concentration still extreme. Four 10%+ customers in Q4 FY2026 (34% / 27% / 16% / 10%) — top three ~77% of revenue. A single hyperscaler delay would materially hit a quarter (cf. Feb 2023 demand cut that hammered FY2024).
3nm supply tightness + supply chain concentration. Dan Fleming: supply chain discussions will "stay popular throughout the next year or even longer." All 200G/lane products use 3nm; AEC cable assembly still depends on BizLink as sole supplier.
Valuation prices in flawless H2 execution. At 56x P/E(ttm) and ~$40B+ market cap, the stock prices in optical hitting >$600M and AEC growing through cycle. Any slip in DustPhotonics or 200G ramp would compress the multiple.

Next 12 Months

Q1 FY2027 guide $465-475M with non-GAAP GM 67-69%. Mid-single-digit sequential growth in H1, then inflection in H2 driven by optical ramp. Q4 dilluted share count ~199M.
ZeroFlap Optics, SiPho PIC, and Optical DSP each >$100M in FY2027. ZeroFlap Optics has three-digit ASPs; discrete DSPs and SiPho PICs are two-digit ASPs — so ZeroFlap is the largest optical contributor at the >$600M level.
DustPhotonics integration is the key Q1-Q2 execution milestone. Closed last week; $750M net cash deployed. Integration into ZeroFlap platform deepens telemetry / diagnostics — initial CPO/NPO revenue expected FY2028.

Next 12-24 Months

FY2028 ramps: OmniConnect Weaver gearbox + ALCs. Weaver enables 10x+ memory bandwidth for inference XPUs; Positron's 2TB LPDDR design supports $2-3K Weaver content per GPU. ALCs use microLED for 30m reach with AEC-class reliability.
Optical could cross 50/50 vs. copper within 2-3 years. Brennan: pluggable optics TAM is "significantly larger" than AEC TAM; "optical could actually exceed copper in the upcoming years." Validates the strategic case for the DustPhotonics buy.
CPO / NPO revenue beginning FY2028. Tight DSP-PIC integration after the DustPhotonics close gives Credo a direct path into co-packaged and near-packaged optics as scale-up networks evolve; this is the longer-tail TAM lever beyond pluggable optics.

Q4 FY2026 = 3/6 — passes R40>40%, TTM OP QoQ>10%, and Debt/EBITDA<3.5. Misses are FCF/OP>60% (still 58% but climbing), R40 acceleration (decel from peak 318%), and TTM OP QoQ acceleration (decel from +90%).
Peak passes 5/6 in Q3 FY2025 coincided with stock $70 — the first big leg up. The current 3/6 reading is mid-cycle: scorecard typically lags inflection points by 1-2 quarters because TTM averages mask sequential acceleration.
R40 still 207% — the highest level in our entire coverage universe. Even as scorecard passes are mid-pack, the absolute R40 magnitude reflects hyper-growth still in motion. FCF/OP at 58% is 2pp short of the 60% threshold and likely to cross in FY2027 as inventory build moderates.

Q3 FY2026 Key Data, reported 2026.04.14

Revenue $407M (+201% YoY); OM 37%; R40 +238% — highest in our coverage. Non-GAAP net margin 51.3% ($209M on $407M revenue). Operating cash flow $166M in Q3 (record). Debt/EBITDA 0.0x.
Top 3 customers = 88% of Q3 revenue; Amazon (~39%) remains the largest. AEC adoption inflection drove revenue from $88M/quarter (Q1 FY2025) to $407M/quarter — a 4.6x increase in 8 quarters.
Q4 FY2026 guided $425M-$435M — another sequential record. Non-GAAP GM 64-66% (below Q3's 69% on product mix). FY2026 total ~$1.3B vs $437M FY2025 — 3x increase. FY2027 guided >50% YoY (~$2B).

Key Takeaways from Earnings Call

DustPhotonics acquisition reshapes Credo into a vertically integrated optical connectivity platform — from copper to optical, chip to cluster. SiPho PIC technology in-house expands Credo into the optical transceiver market (SiPho PIC TAM ~$6B by 2030). Combined portfolio (ZeroFlap Optical Transceivers + Optical DSPs + Silicon Photonics) expected to generate >$500M in optical revenue in FY2027.
Three new product pillars expanding TAM to >$10B. ZeroFlap Optics (optical DSPs with telemetry, ramp pulled forward to Q1 FY2027 with 4+ customers qualifying), Active LED Cables (MicroLED-based pluggables reaching 30m), and OmniConnect Gearboxes (disaggregated memory enabling 30x HBM capacity). Combined TAM is 3x larger than 18 months ago.
Customer concentration, AI capex cyclicality, and supply chain are the bear case. Top 3 customers = 88% of Q3 revenue (Amazon was 67% of FY2025; remains the largest at ~39%). The Feb 2023 demand cut by the then-largest customer hammered FY2024 — concentration risk is real. 100% data center exposure means any AI capex moderation could trigger rapid revenue decline.
