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 | GitLab | Celestica | |
|---|---|---|---|
| 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 FY2026 10-K (year ended 2026-01-31) shows real expansion inside the installed base: 118% Dollar-Based Net Retention, Base Customers up to 10,682 from 9,893, customers above $100,000 of ARR up to 1,456 from 1,229, and $1.0 million ARR customers "to 155 from 123, an increase of 26%". But the filing concedes "limited barriers to entry" and names "Microsoft Corporation, which owns GitHub" as principal competitor. Retention decelerates (130% FY2024, 123% FY2025, 118% FY2026), and since DBNR is reported "on a threshold basis of 130%," the FY2024 figure is a cap and the slide is steeper than it looks. Narrow, not wide: expansion must be re-won against a bundled hyperscaler. | narrow The FY2025 10-K shows a real but bounded edge. On the durable side, Celestica is increasingly engaged as an ODM: its HPS business co-designs (JDM) or fully designs the platforms it builds, it states 'We have hardware and software patents that are integral to our HPS business' and that 'our increased R&D activities have resulted in the growth of our dependence on our patent portfolio', and HPS reached 41% of total revenue in 2025 (from 21% in 2023) at a margin profile the filing says is higher than traditional EMS work. On the limiting side, the same filing concedes 'Some of our competitors have greater scale and provide a broader range of services than we provide', the master supply agreements 'do not typically guarantee a particular level of business or fixed pricing', work is won 'on a program-by-program basis', and the top 10 customers were 79% of 2025 revenue with three customers individually at 32%, 14% and 12%. An advantage that must be re-won each program against greater-scale rivals, for a handful of buyers who can in-source, is narrow rather than 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 Stickiness comes from platform embedding, not IP. The 10-K rests differentiation on "our single platform with a unified data model," on "Consolidation of multiple tools into a single platform," and on deployment inside the customer's own perimeter for regulated buyers. Replacement means re-integrating a toolchain and re-certifying compliance. IP is the wrong label: only "16 issued patents and 25 pending patent applications," plus open-source licenses granting "broad permissions to use, copy, modify, and redistribute." The no-lock-in claim is the filing's own characterisation, footnoted to a Forrester study "commissioned by GitLab." | switching costs Cost scale is explicitly not the source: the 10-K states competitors have greater scale and a broader service range. What does bind a customer is the design-in. Within HPS, Celestica 'design[s] and manufacture[s] products, either as customized solutions, white box solutions or under Joint Design and Manufacturing (JDM) engagements', holds 'hardware and software patents that are integral to our HPS business', and delivers 'complete platform solutions... integration and orchestration of various technologies into rack-scale designs'. The filing adds that 'a majority of these supply agreements also require the customer to purchase unused inventory that we have purchased to fulfill that customer's forecasted manufacturing demand', a contractual cost of walking away mid-program. Moving a qualified, jointly designed rack-scale platform to another ODM means requalifying a design Celestica partly owns, which is friction the commodity assembly work does not carry. |
| 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." | fast follower The 10-K positions GitLab against a leader rather than as one: "Our principal competitor is Microsoft Corporation, which owns GitHub." Competition reads from the challenger side, differentiating "from GitHub through flexible deployment options that work within enterprise security and compliance requirements, LLM neutrality with self-hosted gateway support" and an open core model. On AI it follows: Duo Agent Platform went "Generally available in January 2026," the last month of the fiscal year. What keeps it a follower rather than behind is cadence, "a new version of our software every month for 172 months in a row," plus a regulated-deployment franchise a SaaS-first rival does not cover. | at parity The 10-K claims no share leadership. It states plainly that 'Some of our competitors have greater scale and provide a broader range of services than we provide', and lists Hon Hai, Flex, Jabil, Sanmina, Benchmark and Plexus in EMS plus Quanta, Wiwynn and Accton in ODM. Its stated competitive advantage is execution quality, not position: 'our track record in advanced manufacturing capabilities, design and engineering, quality, delivery, managing complexity and responsiveness'. It is also winning: CCS revenue grew 42% to $9.19 billion and total revenue reached $12.39 billion in FY2025. Competing on comparable terms with a field it neither leads nor trails is parity. |
| 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 FY2026 gross margin was 87% against 89%, with cost of revenue up $35.6 million "primarily due to an increase of $18.4 million in third party hosting costs for SaaS and cloud usage," and management expects SaaS and Duo mix to bring costs that "may adversely impact our gross margins." Strain is explicit: GitLab "may be required to reduce our prices," competitors "may offer their products and services at a lower price or for free," and it "implemented user limits on our free SaaS product." Power retained: Premium lists at $29 per user/month billed annually, and seats bundle $12 and $24 of GitLab Credits. But "A majority of our subscriptions are on a one-year period." | weak The filing describes price as contested by contract, not set by Celestica: master supply agreements 'do not typically guarantee a particular level of business or fixed pricing', 'Some of these agreements require us to provide specific price reductions to our customers over the term of the contracts', and the Item 1A risk factor 'We operate in an industry comprised of numerous competitors and aggressive pricing dynamics' says competitors may be 'willing to, or able to make sales or provide services at lower margins than we do'. The site's fundamentals show gross margin at 12.06% in FY2025, up from 8.96% in FY2022, 9.47% in FY2023 and 10.72% in FY2024 — improving, but still low double digits, and the filing attributes the higher margin to mix (HPS is 'higher margin profile than our traditional EMS businesses' and went from 21% to 41% of revenue over the same span) rather than to raising prices. |
| 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. | GitLab sells a single-platform DevSecOps toolchain defended by workflow lock-in rather than intellectual property: a unified data model plus deployment flexibility, including single-tenant "Dedicated for Government with FedRAMP compliance," makes it hard to remove where data residency is contractual. The installed base expands: 118% Dollar-Based Net Retention, 10,682 Base Customers, 1,456 above $100,000 of ARR, 155 above $1.0 million (up 26%), over 70% of ARR from public sector and enterprise. The filing supplies the counterweight: "limited barriers to entry," Microsoft/GitHub as principal competitor, 16 issued patents. Retention (130 to 123 to 118, the 130 a cap), gross margin (89% to 87%) and a January 2026 AI launch point to compression at the commodity end. No source measures market share, so every share band is "unknown". | Celestica is a contract design and manufacturing company that has been pulled up the value chain by the AI data-center build-out. Its CCS segment, which builds networking switches, optical systems, data center racks, servers and storage for hyperscalers and other cloud and AI service providers, grew 42% to $9.19 billion in 2025, and Communications alone went from 33% of revenue in 2023 to 57% in 2025. The part of that business with a defensible position is HPS, where Celestica is the designer rather than the assembler: HPS revenue rose 81% in 2025 to 41% of the total, carries a higher margin than traditional EMS work, and rests on a patent portfolio the filing calls integral to the business. That design-in position is what separates it from pure build-to-print capacity. What caps the moat is the customer side of the ledger. The 10-K describes an industry where 'aggressive pricing is a common business dynamic', where master supply agreements guarantee neither volume nor price and some of them 'require us to provide specific price reductions to our customers over the term of the contracts', and where the company bids program by program against Hon Hai, Flex, Jabil, Sanmina, Benchmark and Plexus on the EMS side and Quanta, Wiwynn and Accton on the ODM side, plus Arista and Cisco where a customer might buy an off-the-shelf switch instead. Revenue concentration has tightened as the AI mix grew, from 64% of revenue in the top 10 customers in 2023 to 79% in 2025, with a single customer at 32%. The company also notes its HPS offerings can compete with a customer's own hardware, which may 'negatively impact our relationship with, or result in a loss of business from, such customers'. So the profile is a genuine but program-scoped advantage, held by a company whose fortunes turn on a few buyers' capital plans. |
| 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. | GitLab sits at the software-tooling layer, not compute or models. It consumes third-party LLM capacity — marketing "LLM neutrality and support for self-hosted AI gateways, including air-gapped environments" — so it captures no model-layer economics and bears inference as COGS, visible in the $18.4 million rise in hosting costs. Its distinctive position is the regulated perimeter. | Celestica sits between component suppliers and the hyperscale buyer, and owns the design only in part of that span. It 'procure[s] substantially all of our materials and components on behalf of our customers pursuant to individual purchase orders that are generally short-term in nature', then designs, assembles, integrates at rack scale and tests the switches, optical systems, servers, storage and data-center racks that cloud, AI and enterprise customers deploy. In ATS it is a pure EMS contractor that does 'not generally collaborate with ATS customers on the design of the solutions we manufacture'; in HPS it is the designer of record or a joint designer. The economics follow that split: the segment where it holds design IP is the one with the higher margin profile. |
