Ambarella, Inc. is a fabless semiconductor company that designs and sells low-power, high-definition video compression, image processing, and edge-AI inference chips. Its products are used in automotive driver-assistance/autonomous systems, IP security cameras, drones, robots, wearables, and other vision-enabled devices. The company reports a single operating/reportable segment: semiconductor products. Therefore, under ASC 280, there is no audited segment-level P&L split; segment revenue is 100% semiconductor products. [1]

From the fiscal-year 2025 Form 10-K, Ambarella reported:

The FY2024 revenue decline was a major reset for the company: Ambarella went from roughly $337M in FY2023 revenue to $226.5M in FY2024, a decline of approximately needs primary source validation in exact percentage terms, but the 10-K confirms the sharp contraction. [1]

Because Ambarella has one reportable segment, a true segment revenue mix is not audited. However, company disclosures in the FY2025 10-K and earnings commentary break revenue by target market. Based on the filings and investor commentary, the approximate mix is:

This is not a formal SEC segment disclosure. Treat the auto/IoT mix as a management operating view, not ASC 280 segment revenue. [1]

From the FY2025 Form 10-K and Q4 FY2025 earnings release:

Ambarella remains GAAP loss-making. The company has a high gross-margin profile typical of fabless, IP-heavy chip companies, but operating expenses — primarily R&D — consume gross profit. The company’s operating margin is negative; exact operating-loss dollars in the FY2025 10-K are needs primary source validation if quoting beyond the net-loss figures above. [1]

Ambarella monetizes through unit sales of semiconductor chips. The 10-K does not disclose material recurring software/royalty revenue that changes the model. Revenue recognition is tied to product shipments, typically to distributors or directly to OEM/ODM customers. There is no meaningful SaaS-like recurring revenue stream visible in the filings. [1]

The company does not disclose chip unit volumes or average selling prices in its 10-K, so chip-level unit economics cannot be calculated from primary filings. As a company-level proxy:

Gross profit per revenue dollar = GAAP gross margin = $0.61 per $1.00 of revenue in FY2025, or $0.63 on a non-GAAP basis. [1]

This is the cleanest officially supportable unit-economic proxy. Because Ambarella does not disclose unit shipments, ASP, or per-unit gross profit, any deeper chip-level unit economics would be derived from unaudited assumptions and is needs primary source validation.

The immediate payers are semiconductor distributors and OEM/ODM customers. Ambarella’s 10-K discloses significant reliance on one distributor:

• WT Microelectronics Co., Ltd., a Taiwan-based electronics distributor, accounted for approximately 64%–67% of revenue in recent fiscal years. The exact FY2025 and FY2024 percentages as disclosed in the 10-K are:
• FY2025: ~63.9% of revenue
• FY2024: ~66.5% of revenue

Source: AMBA FY2025 Form 10-K, customer-concentration disclosure. [1]

This is a load-bearing claim because it directly affects revenue quality and counterparty risk. It is single-source — it comes from Ambarella’s own filing, not an independent source. It is a direct primary-source fact, so it may remain single-source under the requested rules, but confidence should be tempered because no independent audit of end-customer identity is possible from that disclosure. [1]

No other customer above 10% was identified by name in the available filings. The underlying end customers are largely Asian OEM/ODM and automotive Tier-1 supply-chain participants that buy through distribution. [1]

This calculation tests the scale contradiction raised by the competitor filing below.

Formula

`text

AMBA_auto_rev = AMBA_total_rev × auto_mix

AMBA_share_of_AMBA_plus_NVIDIA_auto =

AMBA_auto_rev / (AMBA_auto_rev + NVIDIA_auto_rev)

`

Base case

`text

AMBA_auto_rev = 250.7M × 0.68 = $170.5M

AMBA_share = 170.5 / (170.5 + 1,090) = 13.5%

Sensitivity table

From the 10-K business and revenue-disclosure sections, customer classes include:

Ambarella does not individually name its largest end OEMs in its 10-K as >10% customers. The only named >10% customer in the available filing is the distributor WT Microelectronics Co., Ltd. [1]

• Automotive buyer: Tier-1 electronics supplier or OEM ADAS team choosing a perception/domain-control SoC. Purchasing criteria: safety, power envelope, AI performance, software support, long-term supply. [1]
• IoT/security buyer: ODM building IP cameras, body cameras, doorbells, drones, or robots. Purchasing criteria: video quality, AI features, power, system cost. [1]

No end-buyer names were used from outside filings. Any specific end-OEM relationship implied by press or industry reports is needs primary source validation.

FY2026 (ended Jan 31, 2026) revenue $390.7M (+37% YoY). Edge AI ~80% of revenue, growing ~50% YoY. Non-GAAP net income ~$27M ($0.62 diluted EPS) — returned to profitability. Gross margin low 60s, expanding with automotive/robotics mix. Net cash ~$265M, no debt.

Layer 5 (Edge Compute). The bet is that edge AI vision — running perception models locally on low-power silicon rather than in the cloud or on power-hungry GPUs — becomes the standard architecture for robots, drones, and embedded automotive vision. AMBA's 15+ year software investment and 200+ AI model support create a meaningful switching cost once designed in.

1. Growth re-acceleration: Q2 FY2027 revenue $108.1M (+13.2% YoY). Q3 FY2027 guidance $115.0–124.0M (midpoint $119.5M) = +10.5% QoQ — breaks the ~$100M 3-quarter plateau the 08-11 note flagged as "plateaued/decelerating."
2. Operating-leverage bridge: Q3 midpoint $119.5M × 59.5% non-GAAP GM = ~$71.1M gross profit − ~$58M non-GAAP opex = ~$13.1M non-GAAP op income (~11% margin) vs Q2 $8.2M net income (7.6% margin) — the first clear opex-leverage inflection.
3. Cost-of-moat vs moat-defended (revealed preference): NXP rumored ~$3.3B (~8.4× revenue) bid for a ~$390M-revenue / 50M-installed-base / 200-model moat. No signed agreement exists; standalone CEO messaging suggests the deal has not progressed — the moat is validated by revealed preference, but the equity re-anchors to standalone fundamentals.
4. Non-GAAP net margin: $8.2M / $108.1M = 7.6% — thin; GAAP still −$6.7M loss.
