Based on Broadcom's SEC filings, the single customer accounting for ~30% of revenue is not named directly by Broadcom. However, the filings reveal a clear picture:

Broadcom's largest customer is Apple Inc. — though the name doesn't appear in the 2025 10-K. Here's the evidence:

• In the FY2024 10-Q (for the quarter ended February 4, 2024), Broadcom explicitly disclosed: "We believe aggregate sales to *Apple Inc., through all channels, accounted for approximately **17% and 20% of our net revenue for the fiscal quarters ended February 4, 2024 and January 29, 2023, respectively."*

• In the FY2025 10-K, the customer concentration language shifted. Broadcom now references one customer (a distributor) accounting for 32% of net revenue in FY2025 and 28% in FY2024. That distributor is widely understood to be WT Microelectronics, which ships Broadcom chips primarily to Apple for iPhone and other wireless components.

• Importantly, Broadcom's custom silicon solutions (ASICs/XPUs) for AI are a growth driver with multiple hyperscaler customers (Google, Meta, etc.), but the ~30% figure aligns with the wireless/AI chip business that flows through distribution — and Apple has historically been Broadcom's largest end customer for wireless components.

Bottom line: The customer representing ~30% of revenue is Apple (via distributor WT Microelectronics), driven by Broadcom's RF/wireless chips used in iPhones and other Apple devices.

Let me dig deeper into the specifics of the Broadcom-Apple relationship — the distribution arrangement and the actual products involved.The SEC filings reveal a very clear and nuanced story. Here are the key findings:

1. Why Broadcom doesn't sell directly to Apple — the distributor model

Broadcom does not sell directly to Apple. Instead, Broadcom sells chips to WT Microelectronics Co., Ltd., a large Taiwan-based electronics distributor, which then supplies Apple and Apple's contract manufacturers (like Foxconn).

This is explicitly stated in the FY2023 10-K and FY2024 Q1 filing: - "Direct sales to *WT Microelectronics Co., Ltd., a distributor, accounted for 21% and 20% of our net revenue for fiscal years 2023 and 2022, respectively."* - The same filing separately states: "We believe aggregate sales to *Apple Inc., through all channels, accounted for approximately 20% of our net revenue for each of fiscal years 2023 and 2022."*

So: Broadcom → WT Microelectronics → Apple / Foxconn. The distributor handles logistics, credit risk, inventory management, and the complexity of delivering to Apple's global network of contract manufacturers. This is standard in the semiconductor industry — it offloads working capital and supply chain complexity from the chipmaker to the distributor.

By FY2025, Broadcom stopped naming Apple or WT Microelectronics separately. The 10-K simply says "direct sales to one semiconductor solutions customer, which is a distributor, accounted for 32% and 28% of our net revenue for fiscal years 2025 and 2024." That unnamed distributor is almost certainly WT Microelectronics, with nearly all those chips flowing through to Apple.

2. What Broadcom sells to Apple — NOT "Apple Silicon"

The products Broadcom supplies to Apple are RF (radio frequency) components, not the main processor chips:

• FBAR filters — proprietary film bulk acoustic resonator filters used in iPhones to prevent signal interference across multiple frequency bands
• RF front-end modules — multi-chip modules that integrate transmit/receive switching and filtering
• Wi-Fi/Bluetooth combination chips
• Custom touch controllers — process signals from iPhone/iPad touch screens
• Inductive charging ASICs — for wireless charging

3. "Apple Silicon" is entirely Apple's own work with TSMC — Broadcom has no role

Apple Silicon (the A-series chips in iPhones, M-series chips in Macs) is designed entirely by Apple's internal chip design teams and manufactured directly by TSMC. Broadcom is not involved in these processors at all.

Broadcom's Custom Silicon / ASIC / XPU business — mentioned heavily in the 2025 10-K — serves an entirely different set of customers: hyperscalers and AI companies (widely understood to be Google for TPUs, plus Meta and others) who need custom AI accelerators for data centers. These are not Apple and they are not related to RF wireless components.

In summary: Broadcom deals with Apple indirectly through WT Microelectronics as a matter of supply-chain logistics — it's how the semiconductor industry works for high-volume mobile components. The products are RF filters, Wi-Fi/Bluetooth chips, and touch controllers, not Apple Silicon processors. Apple's own chips are designed by Apple and fabbed by TSMC with no Broadcom involvement.

That's the right question — and the answer lies in how the numbers have shifted between FY2024 and FY2025.

The SEC filings show a dramatic change:

FY2023 → FY2024 (the old picture): - WT Microelectronics: ~21% of revenue - Apple (end customer, through all channels): ~20% of revenue - These two figures were disclosed separately, and Apple was explicitly named

FY2025 (the new picture): - One unnamed distributor: 32% of revenue - Apple's name disappears entirely from the filings - The distributor figure jumped from ~21% to 32%

Why the jump from ~20% to ~32%?

The distributor is still almost certainly WT Microelectronics, and Apple is still the dominant end customer behind it. But the revenue surge is not just about RF filters for iPhones. Here's what changed:

1. AI is now flowing through the same channel

Broadcom's FY2025 10-K describes its custom AI accelerators (XPUs) as being sold to "hyperscalers and companies with AI frontier models." However, the document also notes that Broadcom now sells AI racks and systems based on XPUs — and that some customers are leasing rather than buying, with alternative financing and deferred payment models.

The important clue: in the FY2025 10-K, the 32% customer is described as "one semiconductor solutions customer, which is a distributor" — the same language used for WT Microelectronics in prior years. But the revenue has grown far beyond what Apple's RF/wireless business alone would account for.

2. The most logical explanation: Apple's AI infrastructure buildout

Apple has been aggressively building its own AI data center infrastructure (Private Cloud Compute, Apple Intelligence). The expansion in that distributor relationship from ~20% to 32% lines up with Apple now buying not just iPhone RF components but also networking silicon (Ethernet switches, NICs, PCIe) for its AI server buildout through the same distribution channel — plus Broadcom's ASIC/XPU revenue increasingly flowing through distributors.

3. Broadcom deliberately obscures this now

Broadcom stopped naming Apple and WT Microelectronics in FY2025. This is likely strategic — as the relationship grows and diversifies beyond just iPhone components into AI infrastructure, Broadcom understandably wants to keep the specific end customer(s) confidential. Apple has always been notoriously private about its supply chain.

The bottom line: The customer at ~30% is almost certainly still Apple (via WT Microelectronics), but the revenue has expanded meaningfully beyond iPhone RF/wireless components. Apple's AI infrastructure buildout — using Broadcom's networking and connectivity silicon — likely accounts for the growth from ~20% to ~32% of Broadcom's revenue. Apple doesn't deal with Broadcom directly because the distributor model handles credit, inventory, and logistics across Apple's global manufacturing network more efficiently than direct sales would.

Excellent questions. Let me dig into the financial mechanics and credit dynamics at play here.This is exceptionally revealing. The filings expose a complete financial architecture behind the distributor relationship. Here's what's really going on:

The AR concentration blew up — and it's not about credit risk at all

The most striking number in the FY2025 10-K:

"One customer accounted for *44%** and 18% of our net accounts receivable balance as of November 2, 2025 and November 3, 2024, respectively."*

AR concentration from the distributor jumped from 18% to 44% in a single year — while the revenue share grew from ~28% to 32%. The receivables are growing far faster than the revenue share.

The factoring machine reveals the true answer

Broadcom immediately sells most of these distributor receivables to banks:

Broadcom doesn't wait to collect from the distributor. It sells the receivables non-recourse to third-party financial institutions. The distributor never really carries credit risk with Broadcom — within days or weeks, a bank owns that receivable.

So to your direct question — no, this is not about Apple needing credit Broadcom can't provide. Apple has $65B+ in cash. The distributor isn't solving a credit problem for Apple. The distributor, paired with Broadcom's immediate factoring, is solving something else entirely.

What's really happening: a working-capital and supply-chain machine

Here's the full picture:

1. Why WT Microelectronics? Apple's iPhone production involves dozens of contract manufacturers (Foxconn, Pegatron, Wistron) across multiple countries. WT Microelectronics handles the logistics of getting the right Broadcom chips (RF filters, Wi-Fi/Bluetooth, touch controllers) to the right factory at the right time. Broadcom doesn't want to manage that complexity. Apple doesn't want to either — it wants one consolidated supplier interface.

2. Why the factoring? Broadcom sells ~$7.4B of receivables to banks annually. This converts AR into immediate cash, keeping Broadcom's reported AR balance artificially low ($7.1B on $65.8B of revenue is remarkably lean). The factoring fees are described as "not material" — meaning banks are offering very cheap rates, likely because the underlying end-obligor is Apple and the credit quality is pristine.

3. The 44% AR spike is timing, not distress. The jump in FY2025 AR concentration from 18% to 44% is almost certainly because Broadcom shipped a massive volume of chips late in Q4 FY2025 (likely for the iPhone 17 launch cycle), and those receivables hadn't been factored yet at the quarter-end cut. The working capital note even says the AR increase was "primarily due to higher billings."

4. Payment terms remain short, not stretching. The filings explicitly state: "Payment terms and conditions vary by contract type, and terms between invoicing and when payment is due are short-term in duration... payment terms are generally structured to provide the customer with predictable and defined payment schedules." Nothing in the filings suggests Broadcom or WT Microelectronics is extending longer payment terms to Apple. The distributor credit allowances (price adjustments/rebates) were $439M in FY2025 — relatively stable and consistent.

The bottom line: The distributor isn't a workaround for Apple's inability to pay — it's a supply-chain logistics layer that handles multi-factory delivery across Asia, plus a working-capital optimization tool for Broadcom. Broadcom books the revenue to WT Microelectronics, then immediately sells the receivable to a bank via factoring, converting the sale into cash within days. Apple pays WT Microelectronics on standard terms. Everybody gets what they want: Broadcom gets immediate cash flow, Apple gets simplified procurement, and the banks earn a small spread on pristine Apple-linked paper.

Great question. Let me look into NVIDIA's customer concentration and sales model — it's a fundamentally different dynamic from Broadcom's.No — NVIDIA's model is fundamentally different. It does not use the Broadcom-style distributor model for its GPU/data center business. Here's the contrast:

How NVIDIA actually sells to hyperscalers and data centers

NVIDIA's SEC filings reveal a multi-layer channel that Broadcom doesn't use:

1. Direct customers — NVIDIA sells directly to a diverse set of buyers: - CSPs (Microsoft Azure, Google Cloud, AWS, Oracle Cloud) - OEMs (Dell, HPE, Lenovo) - ODMs - System integrators - Distributors - Hyperscale companies

In Q3 FY2026, four direct customers each represented 22%, 15%, 13%, and 11% of NVIDIA's revenue. These are typically large ODMs/system integrators and cloud providers buying directly.

2. Indirect customers — this is the critical layer. NVIDIA explicitly discloses that the largest hyperscalers often buy indirectly. For example, "a large CSP which primarily purchases indirectly through multiple system integrators and distributors" has been estimated at up to ~22% of total revenue in some quarters.

3. The Taiwan pass-through — this is enormous. NVIDIA notes: "86% of Data Center revenue from Taiwan-headquartered customers is attributed to end customers based in the United States and Europe." In Q3 FY2026, Taiwan-headquartered direct customers accounted for $13.8B of revenue (24% of total). This means companies like Foxconn/Hon Hai, Wistron, and other Taiwanese ODMs buy NVIDIA GPUs and then assemble them into server racks that ship to AWS, Microsoft Azure, Google Cloud, Meta, etc.

The key difference from Broadcom/Apple

So who are NVIDIA's direct customers?

The 22% customer ("Customer A") is widely believed to be a large ODM like Foxconn/Hon Hai or Wistron — they buy GPUs from NVIDIA, assemble them into server racks with CPUs, memory, and networking, and ship completed systems to AWS, Microsoft, Meta, etc.

But critically, the hyperscalers also do buy directly from NVIDIA. The filings list CSPs and hyperscale companies among direct customers. Microsoft, Amazon, and Google all have direct procurement relationships with NVIDIA. The indirect channel through ODMs exists because GPU servers need to be assembled into complete racks — it's an integration step, not a credit or logistics workaround.

No factoring. Unlike Broadcom's ~$7.4B in annual AR factoring, NVIDIA's filings show no accounts receivable factoring program. NVIDIA carries its receivables on balance sheet — trade AR was higher but in proportion to the revenue scale.

Bottom line: NVIDIA's channel model reflects the complexity of its product, not a credit or logistics avoidance strategy. GPUs need to be integrated into server boards, tested, and assembled into racks. ODMs like Foxconn provide that manufacturing step. But the CSPs also maintain direct relationships with NVIDIA. This is fundamentally different from Broadcom routing everything through WT Microelectronics for Apple — which is about simplifying multi-factory delivery of standardized commodity components, then immediately factoring the receivables.
