Compare moats
Up to three covered companies, band by band. Every call is a curated editorial judgment, never a disclosed figure — and every band carries its cited basis.
| Amkor Technology | Vertiv | AMD | |
|---|---|---|---|
| Moat rating | narrow The FY2025 10-K describes a real but bounded edge. On the plus side, Amkor says "Our scale and geographic diversity allow us to qualify production at multiple sites, optimize asset utilization and absorb large orders that require quick turnaround." It also says "Amkor has built long-standing relationships with most of the world's leading semiconductor companies over the last five decades." And it says that "in line with industry practice, customers usually require us to pass a lengthy and rigorous qualification process that may take several months". It falls short of wide because the same filing calls the market "highly competitive", names ASE Technology, JCET Group and Powertech Technology as rivals, and says Amkor faces Asian providers "including companies with significantly greater processing capacity, financial resources". It also says foundries "substantially larger than us" have expanded into packaging and test, and that IDMs and foundries "may decide to shift some or all of their outsourced packaging and test services to internally sourced capacity". Returns are thin: MD&A gross margin was 14.0% in 2025, 14.8% in 2024 and 14.5% in 2023, with a 7.0% operating margin in 2025. | narrow The FY2025 10-K splits its competition into niche players (Delta, Stulz, Johnson Controls, Socomec) and large-scale globals (Schneider, Eaton, Legrand, Huawei) — real differentiation inside a field that contains several larger diversified rivals. | 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. |
| Moat type | cost scale Part of the 10-K's cost/scale case applies to the whole industry, not to Amkor alone. It says packaging and test service providers "can typically use their assets to support a broad range of customers and multiple end markets, potentially generating more efficient use of their production assets and a more cost-effective solution", in contrast to IDMs running their own lines. The Amkor-specific support is its footprint, which it calls "a key differentiator", and its purchasing scale: "By leveraging our purchasing power and operational expertise, we look to secure favorable pricing and supply agreements for materials and equipment, further enhancing our competitive position." It adds: "We also negotiate worldwide pricing agreements with our major suppliers to take advantage of the scale of our operations." Against other OSATs the scale edge is limited, because Item 1A concedes Asian rivals "including companies with significantly greater processing capacity, financial resources". Multi-month customer qualification and long customer relationships add a secondary switching-cost element. IP is not the source: "Although our patents are an important element of our intellectual property strategy, we are not materially dependent on any one patent or any one technology." | switching costs The filing pairs installed critical infrastructure with a lifecycle service estate — preventative maintenance, project management, acceptance testing, remote monitoring, spares — across more than 40 countries; ripping out the vendor means ripping out the service relationship too. | 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. |
| Leadership | co leader The FY2025 10-K opens: "Amkor is the world's largest U.S. headquartered outsourced semiconductor assembly and test service provider (“OSAT”) and is a global leader in outsourced semiconductor packaging and test services." It claims to be a global leader, not the leader, and its one superlative is limited to U.S.-headquartered providers. It names ASE Technology, JCET Group and Powertech Technology as rivals. It concedes Asian competitors "including companies with significantly greater processing capacity, financial resources". About the key competitive factors it lists, it says only "We believe we are competitive in these areas." | co leader Named against Schneider Electric and Eaton among global competitors; the filing claims differentiation through application expertise and the most comprehensive portfolio — attributed, not independently measured. | 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. |
| Pricing power | weak Item 1A of the FY2025 10-K says "Prices for packaging and test services have generally declined over time, and sometimes prices can change significantly in relatively short periods of time." It also says "We expect downward pressure on average selling prices for our packaging and test services to continue in the future, and this pressure may intensify during downturns in business." MD&A gross margin was 14.0% in 2025 against 14.8% in 2024 and 14.5% in 2023. The notes say the longer test-equipment depreciation life "reduced depreciation expense by approximately $59 million in 2024". Materials alone were 55.2% of 2025 net sales. The customer base is concentrated: the ten largest customers were 72% of 2025 net sales, with Apple at 29.8% and Qualcomm at 11.1%, and the filing flags "a reduction in orders or decrease in price from a significant customer" as a risk. | moderate The filing lists price as one of five competitive bases but leads with reliability and quality, and sells into customers 'in some of the world's most critical industries' — where downtime, not price, is the binding constraint. | 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. |
| Summary | Amkor is a back-end contractor; the 10-K says "We provide turnkey packaging and test services including wafer bump, wafer probe, wafer back-grind, package design, packaging, burn-in, system level and final test and drop shipment services." It also says "Our customers include most of the world's largest semiconductor companies." Advanced Products (flip chip, memory and wafer-level packages) were 82.8% of its $6,708M in 2025 net sales. The durable part of its position is scale and a multi-country footprint, which the filing calls "a key differentiator", backed by multi-month customer qualification and customer relationships it dates back "over the last five decades". On Arizona, the filing says: "Construction began in the second half of 2025, and we believe that this investment will strengthen our ability to serve customers seeking to regionalize their supply chains and will enhance our participation in U.S. semiconductor initiatives." Price caps the moat. The 10-K says "We expect downward pressure on average selling prices for our packaging and test services to continue in the future, and this pressure may intensify during downturns in business." It also says foundries "substantially larger than us" have expanded their operations to include packaging and test services. | Vertiv sells the power and cooling that AI compute physically cannot run without, and its filing leads with 'first-to-market designs engineered for next-gen rack-scale artificial intelligence compute.' Its customers are 'the world's most critical industries' — hyperscale, colocation, neocloud and enterprise data centers — where competition, by the filing's own account, runs on reliability, quality, price, service and customer relationships. The differentiation claims are the company's own; the breadth of the named competitor set is the check on them. | 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. |
| Chain position | Back-end packaging and test step between wafer fabs and chip vendors. The 10-K says "the wafers that we receive from our customers are generally consigned to us", and Amkor serves IDMs, fabless companies, OEMs and contract foundries that outsource packaging and test. | Layer-7 power and cooling under every AI rack. | 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. |
