|---|---|---|---|
| Moat rating | wide A disclosed share that rose while margin expanded. The FY2025 Annual Securities Report and Business Report (84th term, filed 2026-06-26) lists as FY2025 progress: 'Further expanded our market share in the semiconductor tester (ATE) market (CY2024: 58%; CY2025: 65%)', earned on net sales of ¥1,128,610 million at an operating income to net sales ratio of 44.2%, 'an increase of 14.9 percentage points from the previous fiscal year'. The share is a company metric and the filing says so — 'the ratio of Advantest's semiconductor tester sales to the overall size of the semiconductor tester market', where 'The semiconductor tester market size is estimated independently by Advantest based on certain assumptions and available information'. The same filing names seven principal tester competitors (Teradyne, Inc., CCTech, Accotest, YC Corp., Cohu, Inc., UniTest Co., Ltd. and EXICON Ltd.), so this is a lead held against a named field rather than an empty one. | narrow AMD's FY2025 10-K documents real but bounded advantages: approximately 7,200 U.S. patents and roughly 18,900 patent matters worldwide, an outright claim that 'We are the market share leader in semi-custom game console products,' and gross margin of 50% on revenue up 34% to $34.6 billion. The same filing sets the ceiling: 'Some of our competitors may possess stronger market positions, larger customer bases, more design wins, and greater financial, sales, marketing, and distribution resources than us'; Nvidia is named 'the discrete GPU market share leader'; and AMD relies on TSMC 'for the production of all wafers for microprocessor and GPU products at 7 nanometer (nm) or smaller nodes.' Advantages that are genuine, contested, and dependent on a shared foundry are narrow, not wide. | wide Oracle's FY2026 10-K (fiscal year ended May 31, 2026) describes an installed base in which "substantially all customers opt to purchase software support contracts when they purchase an Oracle software license"; that entrenchment shows up externally as the #1 DB-Engines database ranking (August 2026, first of 435 systems) and $638B of contracted Remaining Performance Obligations at Q4 FY2026 (press release, June 10, 2026) — a durable, multi-decade lock on mission-critical enterprise data layers. |
| Moat type | intangibles ip What management itself names as the source of the position is a proprietary platform. The July 29, 2026 Q1 FY2026 results briefing states: 'Our leading SoC Test platform, V93000, has been widely adopted across a broad range of customers in the increasingly complex AI semiconductor markets, where advanced packaging technologies including GPUs, ASICs, and CPUs are being adopted. It serves as a key foundation that underpins our competitive advantage.' The 84th-term report shows the spend behind it: R&D was approximately ¥71.4 billion in FY2024 and ¥78.1 billion in FY2025, 'The number of employees in its research and development division is approximately 30% of the Advantest workforce', and in the Test System Business Segment 'a large and ongoing investment in research and development is necessary in order to maintain market competitiveness'. Its stated IP mitigation is that 'Advantest strategically and proactively files patent applications during product development and prior to product shipment'. | intangibles ip The FY2025 10-K locates the durable asset in design IP rather than manufacturing: 'We rely on contracts and intellectual property rights to protect our products and technologies from unauthorized third-party copying and use,' with approximately 7,200 U.S. patents and about 18,900 patent matters worldwide spanning x86 EPYC/Ryzen CPUs, CDNA/RDNA graphics and the Versal/Zynq adaptive-SoC families, and it credits customer wins to 'our broad IP portfolio and leadership in design, integration and advanced packaging.' It is explicitly not cost_scale: AMD is fabless and 'utilize[s] Taiwan Semiconductor Manufacturing Company Limited (TSMC) for the production of wafers' — the same leading-edge foundry its merchant competitors use, so no manufacturing-scale advantage accrues to it. | switching costs The core moat is the cost of moving mission-critical databases and back-office suites: the FY2026 10-K notes substantially all license customers attach support contracts and that Oracle's Multicloud Database offerings run Oracle AI Database inside other hyperscalers' clouds — monetizing the installed base even when the customer's infrastructure leaves; the KLAS 2026 EHR report shows the same dynamic in health IT, where roughly a third of Oracle Health customers want to leave but feel unable to do so. |
| Leadership | clear leader The 84th-term report discloses Advantest's tester-market share at 65% in CY2025, up from 58% in CY2024, and carries the same 65% among its disclosed management metrics against a target of '58% or more'; the filing defines it as Advantest's semiconductor tester sales over a market size 'estimated independently by Advantest based on certain assumptions and available information'. The July 29, 2026 briefing names the platform behind that share — V93000, 'widely adopted across a broad range of customers in the increasingly complex AI semiconductor markets'. Teradyne, Inc. heads the filing's list of principal tester competitors. | fast follower The FY2025 10-K itself places AMD behind the pace-setter in its two most important markets: 'Our principal competitor in the supply of discrete graphics is Nvidia, who is the discrete GPU market share leader,' and the risk factors state Nvidia 'leverages its market position in data center GPU, financial resources, and proprietary software ecosystem to promote its systems and influences customers who do business with us.' AMD is nonetheless executing 'an annual cadence of leadership for AMD Instinct solutions' and has won gigawatt-scale commitments (OpenAI, 6 GW) — following fast and closely, not setting the pace. | co leader Split by line: clear leader in database (DB-Engines August 2026 ranks Oracle #1 and Oracle-owned MySQL #2 of 435 systems); one of the largest enterprise-application vendors ($15.9B FY2026 SaaS revenue, competing with SAP, Salesforce, Workday and Microsoft per the FY2026 10-K); but in cloud infrastructure a ~4%-share fast-growing challenger behind Amazon (28%), Microsoft (20%) and Google (15%) per Synergy Q2 2026 data (The Register, 2026-08-01), and #2 in US acute-care EHR behind Epic (KLAS 2026). |
| Pricing power | strong Q1 FY2026 gross profit was ¥255,553 million on net sales of ¥367,473 million, and the July 29, 2026 briefing states the resulting figure itself: 'Gross margin reached 69.5%', with 'an operating margin of 51.7%'. Management attributes that level to 'a favorable sales mix and limited inventory valuation losses amid the robust demand environment', not to price, and guides FY2026 full-year gross margin to 66–67% and operating margin to 49.4% after incorporating 'the impact of higher component costs, particularly for memory-related components'. FY2025 closed at a 44.2% operating margin, up 14.9 points year on year, on sales up 44.7%. | moderate FY2025 gross margin was 50%, up from 49% in 2024 per the 10-K — healthy and improving — but the same filing attributes average-selling-price pressure to competitors: Intel 'uses its microprocessor market position to price its products aggressively and target our customers and channel partners with special incentives. These aggressive activities have reduced and may reduce our unit sales and average selling prices for many of our products'. Pricing power is real but contested. | moderate Strong in the installed base — the FY2026 10-K states substantially all license customers purchase support contracts, a recurring stream customers rarely drop — but the same 10-K lists "total cost of ownership" first among key competitive factors and describes intense competition across every segment; AI-infrastructure deals are won against hyperscalers and neoclouds, and Q4 FY2026 SaaS grew a moderate 10% versus 93% for IaaS (press release, June 10, 2026). |
| Summary | Advantest sells the test step that certifies silicon before it ships, and its position there is disclosed rather than inferred: its own tester-market-share metric moved from 58% in CY2024 to 65% in CY2025 (84th-term Annual Securities Report), against a market size the filing says Advantest estimates itself. The lead is concentrated in SoC test — the July 29, 2026 briefing calls V93000 'our leading SoC Test platform' and 'a key foundation that underpins our competitive advantage' — and the customer base runs straight into the AI chain: NVIDIA International, Inc. was ¥228,273 million, or 20.2%, of FY2025 consolidated net sales, having been below the filing's 10% disclosure threshold the prior year, with Taiwan Semiconductor Manufacturing Co., Ltd. at ¥124,922 million, or 11.1%. Economics moved with it: FY2025 operating margin was 44.2%, up 14.9 points, and Q1 FY2026 gross margin reached 69.5%, which management attributes to 'a favorable sales mix and limited inventory valuation losses amid the robust demand environment' rather than to price. The counterweights sit in the same documents. The 84th-term report's customer-trust risk factor warns that if Advantest fails to meet expectations on ramp-up and post-sales service, 'the maintenance or expansion of Advantest's market share may be constrained'; it names separate competitor sets in test handlers (Hon. Precision, CCTech, Cohu, TechWing) and device interfaces (TSE, ISC, BeLINK) where no share is disclosed at all; and the July 29, 2026 briefing guides FY2026 full-year gross margin down to 66–67% having 'incorporated the impact of higher component costs, particularly for memory-related components, mainly in the second half of the fiscal year'. | AMD's edge is architectural design IP executed on someone else's fabs. The FY2025 10-K describes a full-stack portfolio — EPYC server CPUs, Instinct AI accelerators, Ryzen client parts where 'AMD was the first company to integrate a dedicated neural processing unit (NPU) on the same SoC as an x86 CPU for AI PCs,' Radeon graphics, Pensando networking and Versal adaptive SoCs — backed by roughly 18,900 patent matters worldwide, and it discloses gigawatt-scale customer commitments (an October 2025 agreement with OpenAI 'to deploy 6 gigawatts of AMD GPUs,' first gigawatt on Instinct MI450). The same filing bounds that moat: Nvidia is 'the discrete GPU market share leader' and 'leverages its market position in data center GPU, financial resources, and proprietary software ecosystem'; Intel 'uses its microprocessor market position to price its products aggressively'; Arm architectures and customers who 'internally develop products to support similar AI workloads' are named as encroaching; and every wafer at 7 nm or below comes from TSMC. Revenue grew 34% in FY2025 with Data Center up 32%, but the filing's own competitive framing places AMD in the challenger seat rather than the entrenched one. | Oracle pairs the deepest switching-cost franchise in enterprise software — the #1-ranked database (DB-Engines, August 2026) plus Fusion/NetSuite back-office suites, with support attach near-universal per the FY2026 10-K — with a late but explosive push into AI cloud infrastructure: Q4 FY2026 IaaS revenue grew 93% to $5.8B and RPO reached $638B (up 363% YoY), mostly large-scale AI contracts (press release, June 10, 2026). The two reinforce each other via multicloud — Oracle Multicloud AI Database grew 404% in Q4 running inside rival clouds. The offsets: in cloud infrastructure Oracle is still a ~4%-share challenger behind AWS/Microsoft/Google (Synergy Q2 2026 data via The Register), the AI buildout drove FY2026 free cash flow to negative $23.7B, and the Cerner-based Oracle Health business has lost US hospital share for three straight years (KLAS 2026). |
| Chain position | Back-end capital equipment: Advantest's testers certify devices after fabrication, and the 84th-term report's FY2025 major-customer table puts NVIDIA International, Inc. at 20.2% and Taiwan Semiconductor Manufacturing Co., Ltd. at 11.1% of consolidated net sales, with overseas sales 97.8% of the total. | A fabless merchant-silicon designer sitting one layer above the foundries: the FY2025 10-K states AMD relies on TSMC 'for the production of all wafers for microprocessor and GPU products at 7 nanometer (nm) or smaller nodes' and primarily on GLOBALFOUNDRIES above 7 nm, with packaging and test performed by Asia-Pacific ATMP partners — so its cost, supply and cadence are inherited from partners it does not control. | Supply-chain role in AI: OCI sells GPU compute for AI training and inference — the Q4 FY2026 press release attributes most of the $85B sequential RPO increase to large-scale AI contracts (some with customer-prepaid or customer-supplied GPUs totaling $75B) and guides FY2027 total revenue to $90B — making Oracle a primary capacity supplier to AI model builders. |
