|---|---|---|---|
| Moat rating | 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. | narrow The FY2025 10-K's own competitive record cuts both ways. Item 1 says a "high-quality, highly interconnected global portfolio such as ours could not be easily replicated today on a cost-competitive basis," yet Item 1A concedes that competitors have "significantly greater financial, marketing and other resources and more ready access to capital" and that as rivals keep developing space, "rental rates may be reduced or we may face delays in leasing." A durable advantage that its own filing says new supply can price against is bounded, not unassailable. | narrow Real but bounded: the FY2025 10-K reports gross profit at 58.2% of total revenues, a level it records as a decrease - 'Gross profit as a percent of total revenues decreased by 0.3 points, primarily due to product mix' from 58.5% in 2024 - while a shared IG-XL test-program environment spans the FLEX and J750 families. Against that, the filing's own risk-factor heading is 'We are subject to intense competition' and it concedes that 'Some of our competitors have introduced or announced new products with certain performance characteristics that may be considered equal or superior to those we currently offer,' adding that it faces competition 'from emerging Asian companies and internal development at several of our customers.' |
| Moat type | 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. | network effects Item 1 attributes the hard-to-replicate part of the portfolio to connectivity rather than to real estate: "the network density, interconnection infrastructure and connectivity-centric customers in certain of our data centers have led to the organic formation of densely connected data communities that are difficult for competitors to replicate." That community sits on over 232,000 cross connects in over 55 metros, so each network and cloud that lands makes the same building worth more to the next tenant. | switching costs The 10-K's Products section grounds the stickiness in test-program and capital reuse rather than in protected IP: the FLEX Test Platform runs 'The IG-XL™ software operating system which provides fast program development, including instant conversion from single to multi-site test', the J750 'shares the IG-XL software environment with the family of FLEX Test Platform systems,' and its instruments are 'coupled with a universal slot test head design that allows easy test system reconfiguration to address changing test needs.' The filing credits that versatility with making FLEX 'a widely used test solution at OSATs... allowing OSATs to leverage their capital investments.' The same 10-K expressly disclaims an IP-based moat: 'We do not believe that any single piece of intellectual property or proprietary rights is essential to our business.' |
| Leadership | 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 Item 1 claims the title of "the largest global provider of cloud- and carrier-neutral data center, colocation and interconnection solutions," but the Competition section names Equinix and NTT as operators of properties "similar to ours in some of the same metropolitan areas," plus Global Switch and regional operators abroad — a shared top tier on the company's own telling, not a solitary one. | co leader The 10-K opens by calling Teradyne 'a leading global provider of automated test equipment and robotics solutions' - a leading provider, not the leader - and its Competition section names Semiconductor Test rivals non-exhaustively: competitors 'include, among others, Advantest Corporation, SPEA S.p.A., and Cohu, Inc.' It discloses no share figure and warns that competitors' announced products 'may be considered equal or superior to those we currently offer,' which reads as shared leadership rather than a clear lead. |
| Pricing power | 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. | strong FY2025 renewals signed re-priced upward in every bucket — +27.0% on greater-than-1 MW space ($146 to $186 per square foot), +4.6% on 0-1 MW ($268 to $280) and +43.0% on other ($49 to $71) — and MD&A expects average aggregate rental rates on 2026 renewals to be positive against the rates currently paid for the same space "on a GAAP basis and on a cash basis." On costs, the filing says utilities expense "is our largest expense category" and that "the vast majority of the expense is passed directly through to our customers," which it credits with significantly mitigating exposure to power-cost increases rather than removing it. The cap: Item 1A warns competitor development could still force rates down. | moderate Gross profit was 58.2% of total revenues in 2025 against 58.5% in 2024, and the 10-K attributes the 0.3-point decline to product mix; product gross margin fell 0.8 points to 57.3%. The risk factor 'Our operating results are likely to fluctuate significantly' lists 'competitive pressures on selling prices' among factors that 'could impact future operations,' and the same list cites the tendency of customers to 'wait until late in a quarter to commit to purchase... or the hope of obtaining more favorable pricing from a competitor seeking the business' - margin is defended, not expanded. |
| Summary | 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. | Digital Realty rents space, power and connectivity rather than compute: at 2025 year-end its portfolio held 310 data centers and roughly 57.6 million rentable square feet across more than 55 metros in over 30 countries, about 84.7% leased, serving more than 5,000 customers. Two different businesses sit inside that footprint. The greater-than-1 MW wholesale side is a capital-and-power race — 769 MW of projects underway with 64% pre-leased, and land that "could accommodate over 3,500 megawatts of additional data center capacity" — where the 10-K names Equinix, NTT, Global Switch and "various private operators" as rivals and warns that added supply can push rents down. The colocation and interconnection side is the defended half: over 232,000 cross connects and the "densely connected data communities" Item 1 says competitors cannot easily replicate, reinforced by contracts the filing describes as generally running 5-10+ years on large deployments and by improvements "installed at our customers' expense." FY2025 leasing supports that read — renewals signed re-priced +27.0% on greater-than-1 MW space and +4.6% on 0-1 MW — while customer concentration is the offsetting exposure, with the largest customer at roughly 11.7% of annualized recurring revenue. | Teradyne sells the test step that sits between fabrication and shipment, and its hold on customers comes from platform continuity rather than patents. The FY2025 10-K describes one IG-XL software environment shared across the FLEX and J750 test families and a universal slot test head that lets a customer reconfigure a system to address changing test needs, which the filing credits with making FLEX widely used at OSATs because it lets them leverage their capital investments. The margin that continuity sits on is high but not rising: gross profit was 58.2% of revenue in 2025, which the filing records as a 0.3-point decrease from 2024 on product mix, with product margin down 0.8 points to 57.3% and service margin up 2.9 points to 62.9% - and the filing attributes that service gain to the May 2024 sale of the DIS business, not to the platform. It is a narrow moat, not a wide one: the filing names Advantest, SPEA and Cohu 'among others' in Semiconductor Test, warns of internal development at several customers, states that rival products may be 'equal or superior,' and discloses that the five largest direct customers rose to 44% of consolidated revenue in 2025 from 36% in 2024 - buyer power that caps how much of the platform advantage converts to price. |
| Chain position | 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. | Landlord to the AI stack — sells the space, power and interconnection that cloud, network and enterprise tenants run compute in (Oracle, IBM, Meta Platforms, AT&T, Comcast and Lumen are among the customers named in Item 1), with roughly 2.9 GW of total in-place IT capacity. | Back-end capital equipment: its testers sit between fabrication and shipment, and the 10-K states that AI related customer demand drove the majority of revenue in the second half of 2025, with Semiconductor Test at 79% of consolidated revenue. |
