| Moat rating | narrow IBM's FY2025 10-K describes "a highly competitive environment" with "hundreds of competitors" and says IBM is "regularly exposed to new competitors" as it executes its hybrid-cloud/AI strategy, while differentiating through "incumbency with enterprises" and "client relationships and trust" — a real but narrow moat, not a wide one. | wide The fiscal 2026 10-K states 'The strength of our competitive positions in many of our existing markets is primarily due to our leading technology', and frames process control as 'an essential enabler' of the yield ramp in fabs the filing says now cost 'well above $10 billion'. | narrow Ciena's FY2025 10-K describes a technology position that has held but does not lock customers in. On the durable side, the strategy is to "build on and expand our global leadership in optical networking", resting on "our proprietary WaveLogic™ coherent modem technology" and approximately 2,400 issued patents with 800 more pending as of December 2, 2025. On the limiting side, the same filing says competition "remains intense" and features "aggressive selling efforts, including using significant pricing pressure to displace incumbent vendors", that "our customer contracts generally do not include minimum or guaranteed purchases", and that "there is no assurance that we will maintain our incumbency". Concentration cuts the same way: the five largest customers contributed approximately 50% of fiscal 2025 revenue, one cloud provider approximately 18%. Its income statement reports gross profit of $1,878.9M on $4,386.5M of revenue in FY2023, $1,719.6M on $4,015.0M in FY2024 and $2,004.9M on $4,769.5M in FY2025. Self-described leadership in its segments, with customers that are re-won deal by deal, is a narrow moat. |
| Moat type | switching costs The 10-K roots IBM's differentiation in "incumbency with enterprises" and "client relationships and trust" — installed-base lock-in across its hybrid-cloud platform (Red Hat) and enterprise software and infrastructure raises switching costs. | intangibles ip The 10-K reports over 9,100 active patents and over 3,600 pending applications with terms running through 2045, alongside proprietary process-control software (Klarity, I-PAT, aiSIGHT) that turns inspection and metrology data into yield learning. | intangibles ip The FY2025 10-K locates the advantage in owned technology rather than in customer lock-in: "The success of our business and technology leadership depends significantly on our proprietary and internally developed technology." That technology is centred on WaveLogic, which Ciena's fiscal Q3 2026 earnings presentation (the source of the first two product rows below) defines as "Ciena's proprietary family of coherent optical chips — the core technology inside most of our networking products", and it reaches beyond Ciena's own systems: the 10-K's coherent pluggable transceivers use WaveLogic "for use within our systems and third-party equipment". Switching costs are the weaker candidate, because the same filing describes operators disaggregating line systems from modems and competitors using price to displace incumbents. |
| Leadership | fast follower An enterprise incumbent that differentiates via "incumbency with enterprises" but is "regularly exposed to new competitors" in its hybrid-cloud/AI push (FY2025 10-K) — a follower in the current AI cycle rather than its leader. | clear leader The 10-K opens by describing KLA as a supplier of 'industry-leading equipment and services' and attributes its competitive positions 'in many of our existing markets' primarily to leading technology; named competitors are Applied Materials, ASML, Hitachi High-Tech, Lasertec and Onto Innovation. | co leader Slide 6 of Ciena's fiscal Q3 2026 earnings presentation of 2026-09-03 (https://s25.q4cdn.com/550667411/files/content_files/Ex-99-2-2026-Q3-Earnings-Presentation_FINAL-1.pdf) lists "#1 in Data Center Interconnect Globally" (Dell'Oro Group), "#1 in Total Optical Networking in N. America" (Cignal AI, Dell'Oro Group, Omdia) and "#1 in Submarine Networks Globally" (Omdia), with market share measured as of Q2 2026 excluding China, and a caveat that Ciena "has not independently verified" the analyst data. On the company's own presentation of that data, that is the front rank in its core segments, but the presentation does not claim the global lead in total optical networking, and the FY2025 10-K says competition is "dominated by a small number of very large, multi-national companies" - Nokia, Huawei, Cisco, Hewlett Packard Enterprise and ZTE - many of which have "substantially greater financial, operational and marketing resources, and broader product offerings". A shared front rank, led by Ciena where the company-reported rankings measure it, rather than an uncontested one. |
| Pricing power | moderate Gross margin is high and rising (54.9% FY2021 to 58.2% FY2025) on a software-mix shift, but "price" is a principal method of competition per the 10-K and consulting/infrastructure remain price-competitive. | strong Services were approximately 23% of fiscal 2026 total revenues on an installed base that recurs, backlog nearly doubled to $12.57 billion, and SEC-reported net income was 35.6% of revenue in fiscal 2026 with operating income at 41.2% of revenue in fiscal 2025. | moderate Moderate, and improving. The FY2025 10-K's income statement reports gross profit of $1,878.9M on $4,386.5M, $1,719.6M on $4,015.0M and $2,004.9M on $4,769.5M of revenue for FY2023-FY2025, in a market where, the filing says, rivals use "significant pricing pressure to displace incumbent vendors" and "price and total cost of ownership" heads the list of competitive factors. Since then the AI build-out has lifted gross margin: Ciena's fiscal Q3 2026 earnings presentation (https://s25.q4cdn.com/550667411/files/content_files/Ex-99-2-2026-Q3-Earnings-Presentation_FINAL-1.pdf) reports GAAP gross margin of 45.4% against 41.3% a year earlier, on revenue up 37% year over year, and guides fiscal 2027 adjusted gross margin to 45% to 46%. The presentation does not say how much of that is price rather than mix or volume, and the 10-K warns that AI-related demand has led to "a constrained supply environment" that can raise component costs. |
| Summary | IBM's moat rests on deep enterprise incumbency — sticky installed-base relationships across hybrid cloud (Red Hat), enterprise software, and mission-critical infrastructure, plus brand and a large patent base. But its own FY2025 10-K frames "a highly competitive environment" with "hundreds of competitors" and says IBM is "regularly exposed to new competitors" as it pursues hybrid cloud and AI, so the moat is durable but narrow and contested in the AI/cloud growth arena. | KLA sells the inspection, metrology and yield-management layer a fab must run to reach volume production: the 10-K says accelerating the yield ramp ahead of competitors is critical to chipmakers' profitability, and backlog nearly doubled from $7.86 billion to $12.57 billion in the year to June 30, 2026 'due to strong demand driven by the AI infrastructure buildout'. | Ciena is the optical-transport specialist among networking vendors - its fiscal Q3 2026 earnings presentation calls it "the only pure-play optical systems provider operating at scale today" - and its FY2025 10-K builds the business on one proprietary technology, the WaveLogic coherent modem, carried into the 6500 Packet-Optical Platform, Waveserver data center interconnect systems, the 6500 RLS photonic line system and coherent pluggable transceivers sold for Ciena's own systems and third-party equipment. Analyst rankings the company cites in that presentation, which it says it "has not independently verified", put Ciena first in data center interconnect globally, in total optical networking in North America and in submarine networks globally (Q2 2026, excluding China). The AI build-out has turned it into more of a cloud supplier than a telecom one: cloud providers were 53% of fiscal Q3 2026 revenue, revenue rose 37% year over year, and GAAP gross margin reached 45.4%. The 10-K is equally clear about why the position is narrow rather than wide. Competition is "dominated by a small number of very large, multi-national companies", many with greater resources; rivals use pricing to displace incumbents; contracts carry no minimum or guaranteed purchases; the five largest customers were about half of fiscal 2025 revenue; and disaggregation lets an operator buy the line system from one vendor and the modem from another, while the push into data-center interconnects brings Ciena up against Marvell, Credo and Broadcom. |
| Chain position | A hybrid-cloud platform, enterprise-AI (watsonx), and consulting provider to large enterprises — a software/cloud layer of the AI stack. | Sits beside the process steps rather than in them — it measures and inspects what deposition, etch and lithography produce, and TSMC alone exceeded 10% of revenue in each of the last three fiscal years. | Ciena sits between optical-component suppliers and the operators building AI-era networks. Upstream, its FY2025 10-K says its products include "optical and electronic components for which reliable, high-volume supply is often available only from sole or limited sources", built by contract manufacturers with facilities in Canada, Mexico, Thailand, Vietnam and the United States; at November 1, 2025 it carried $826.2 million of inventory and $2.1 billion of purchase commitments. Downstream, the fiscal Q3 2026 earnings presentation puts direct cloud providers at 53% of the quarter's revenue against 37% for service providers, and describes its products as the links between data centers (data center interconnect) and between distributed AI training clusters ("scale-across"). |
