|---|---|---|---|
| Moat rating | narrow Corning's FY2025 Form 10-K (filed 12 February 2026) documents real protection in two places and hedges everywhere else. In Display it states flatly that 'We are the largest worldwide producer of glass substrates for flat panel displays' and credits a 'proprietary fusion manufacturing process, which we invented and is the cornerstone of our technology leadership in the display glass industry'; in Optical Communications it says 'We maintain a leadership position in the segment's principal product groups, which include carrier and enterprise networks'. But the Competition section opens on a company-wide concession - 'Some of these competitors are larger than we are, and some have broader product lines' - and closes that opening paragraph with 'There is no assurance that we will be able to maintain or improve our market position or competitive advantage', a hedge set over the five per-segment paragraphs that follow, the last of which has Life Sciences facing 'competition from large distributors that have pursued backward integration or introduced private label products'. In optical it expects 'industry consolidation, pricing pressure and competition for the innovation of new products' to persist. The risk factors add that Optical Communications and Display 'generate a significant amount of the Company's profits and cash flow' and are 'subject to pricing pressure', while the customer base is concentrated enough that customers 'may possess substantial leverage in negotiating contractual obligations' - the filing's own table puts two combined end customers at 28% of 2025 Optical Communications segment net sales, three at 59% of Display, two at 43% of Specialty Materials and three at 61% of Automotive. Protection that is genuine but confined to part of the portfolio, held against named larger rivals and customers with that much leverage, is narrow rather than wide. | none MaxLinear’s FY2025 10-K does not show a durable advantage. Its income statement reports revenue of $693,263 thousand in 2023, $360,528 thousand in 2024 and $467,641 thousand in 2025, with operating losses of $38,221 thousand, $223,352 thousand and $126,890 thousand. The risk factors say “Increased competition has resulted in price pressure, decreased demand, reduced revenue and profitability, and loss of market share”; the business section says competitors include “companies with much longer operating histories, greater name recognition, and substantially greater financial, technical and operational resources”; and because its products “often are building block semiconductors” it also faces integrated-circuit makers, “some of which may be existing customers or platform partners”. Two customers were 28% of 2025 net revenue and the ten largest 65%, and “substantially all of our sales to date have been made on a purchase order basis”. Gross profit held up - $385,663 thousand, $194,782 thousand and $265,814 thousand for 2023 to 2025 - and the AI optical ramp has lifted 2026 results, but a revenue base that nearly halved in one year and three straight years of operating losses do not evidence a moat. | narrow The independent evidence is a regulator's complaint, not a finding. The FTC, Illinois and Minnesota complaint filed 2025-01-15 (https://www.ftc.gov/system/files/ftc_gov/pdf/DeereCoREDACTEDComplaintCaseNo325-cv-50017.pdf) alleges that "Deere is the world's leading manufacturer of agricultural equipment like large tractors and combine harvesters, and Deere enjoys a dominant share of large tractor and combine sales in the United States", that Deere "possessed monopoly and market power in the sale of Large Tractors and Combines in the United States", and that "There are substantial barriers to entry into the Large Tractor and Combine markets." The share figures behind those claims are redacted in the public version. Deere's FY2025 Form 10-K (fiscal year ended 2025-11-02, filed 2025-12-18) adds the company's own side of the edge: "John Deere's brand recognition is a competitive factor in North America and many other parts of the world", about 2,050 independent dealer locations in the U.S. and Canada, and parts "many of which are proprietary". The limits are in the same 10-K: "The agricultural equipment industry continues to change and is becoming even more competitive through the emergence and global expansion of many competitors", the industry "is also attracting non-traditional competitors, including technology-focused companies and start-up ventures", and construction and forestry (29% of fiscal 2025 equipment net sales) faces Caterpillar, Komatsu, Volvo and others. That supports a narrow rating, not a wide one. The dominance and entry barriers are a plaintiff's allegations, not findings, and the share figures are redacted. They cover U.S. large tractors and combines, inside a segment that was 45% of fiscal 2025 equipment net sales. Deere's own filing describes agriculture as becoming more competitive and construction and forestry as a contested market. |
| Moat type | intangibles ip What the filing keeps pointing at is invented process technology and the patent estate fencing it, not a network and not raw size. The FY2025 10-K repeats 'Patent protection is important to the segment's operations' word for word in four of its five reportable segments - Optical Communications, Specialty Materials, Automotive and Life Sciences - and gives Display a stronger variant, 'Patent protection and proprietary trade secrets are important to the Display segment's operations'. It reports about 11,375 unexpired patents owned worldwide at the end of 2025 (about 4,015 of them U.S.), about 370 U.S. and over 970 non-U.S. grants during 2025 and about 5,650 applications in process, and states 'We have historically enforced, and will continue to enforce, our intellectual property rights.' The single clearest asset is a process rather than a product - the fusion draw Corning says it invented and calls the cornerstone of its display-glass technology leadership, guarded in Display by 'proprietary trade secrets'. Even the cost advantage the filing claims in optical is sourced back to the same place: 'Our large-scale manufacturing experience, fiber process, technology leadership and intellectual property provide cost advantages relative to several of our competitors' - scale is described there as a consequence of the process, not the origin of the advantage, which is why this is an IP-and-know-how moat rather than a cost-scale one. The estate is broad rather than cliff-edged: 'no one patent is considered material to any segment', and about 740 worldwide patents, 6.5% of the portfolio, expire between 2026 and 2028. | none No single source of advantage in the 10-K is strong enough to name. MaxLinear has “over one thousand issued patents” and says consideration under intellectual property sale agreements “has previously been and is currently expected in the future be material”, but the same filing describes its products as building blocks that larger vendors can integrate, says some optical-interconnect customers are “module makers who are vertically integrated, where we compete with internally supplied components”, and claims only that “We believe that we compete favorably” on factors from product performance to price. Its RF-CMOS integration know-how is real, but nothing in the filing shows customers locked in or rivals unable to match it. | switching costs The FTC complaint (2025-01-15) places the advantage in the cost of leaving the installed fleet: "Equipment owners cannot switch from Deere agricultural equipment to other manufacturers' equipment without incurring significant costs", including "the cost of acquiring replacement equipment (often hundreds of thousands of dollars per machine), the cost of learning how to operate new equipment, and the cost of losing data generated by existing Deere equipment", plus the cost of making "mixed fleets" interoperable. The FY2025 10-K describes the assets that create this lock-in: a dealer network of about 2,050 U.S. and Canadian locations, proprietary parts for current and past products, and the John Deere Operations Center, which Item 1A says "stores substantial volumes of data with respect to our customers' operations". Patents are not the main source: the 10-K says it does "not regard any of our businesses as being dependent upon any single patent or family of patents." |
| Leadership | clear leader The FY2025 10-K makes exactly one unqualified rank claim and it is Display: 'We are the largest worldwide producer of glass substrates for flat panel displays', with only AGC Inc. and Nippon Electric Glass Co., Ltd. named as principal competitors. The second-strongest claim is Optical Communications' - 'We maintain a leadership position in the segment's principal product groups, which include carrier and enterprise networks' - asserted against Amphenol, Fujikura and its subsidiary America Fujikura Ltd., Sumitomo and Prysmian Group S.p.A. Those two lines carry the company: Optical Communications was 38% of total segment net sales in 2025 and Display 23%, and the segment table credits them with $1,048 million and $993 million respectively of the $2,747 million of reportable-segment net income. The band is a company-level judgment weighted to them, and it does not extend across the portfolio - Automotive claims only 'a strong market position', and Life Sciences describes itself as 'a leading developer, manufacturer and global supplier of laboratory products for over 110 years' while competing against the much larger Thermo Fisher Scientific Inc. and Danaher Corporation on $972 million of 2025 sales. | fast follower In its fastest-growing line MaxLinear is a second source. Deep Fundamental’s September 27, 2024 deep dive (https://deepfundamental.substack.com/p/deep-dive-optical-module-market) says “Marvell ($MRVL) and Broadcom ($AVGO) are two major suppliers of DSPs, with Marvell holding the top position in the market”, that “Coherent also sources heavily from Marvell, with Broadcom/ Maxlinear potentially serving as second supplier with 20-30% share”, and that MaxLinear offers “DSPs at about half the price of Marvell's if it can achieve a meaningful mass production volume of at least 100K units per month”. Keystone has since reached volume - management said on the Q2 2026 call that it “continues to ramp into high volume production at major hyperscale customers across U.S. and Asia” - but the 10-K names Broadcom, Qualcomm, Realtek, Skyworks, Credo, MediaTek, Marvell, MACOM, Texas Instruments, Analog Devices, Renesas, Microchip and Semtech as primary merchant competitors, and no third-party source found ranks MaxLinear first in any of its markets. | clear leader The independent evidence covers U.S. large farm equipment. The FTC complaint (2025-01-15) states "Deere is the largest manufacturer of agricultural equipment in the United States" and alleges that for each fiscal year from at least 2012 to 2021 Deere's share of large tractors sold in the United States exceeded a figure that is redacted in the public version; the FTC press release of the same day (https://www.ftc.gov/news-events/news/press-releases/2025/01/ftc-states-sue-deere-company-protect-farmers-unfair-corporate-tactics-high-repair-costs) says Deere "maintains a dominant market share position across the large agricultural equipment market". These are a plaintiff's allegations. The band does not extend to construction and forestry, where the FY2025 10-K lists Caterpillar, CNH Industrial, Doosan Bobcat, Hitachi, Komatsu, Kubota, Liugong, SANY, Volvo and XCMG among global competitors and no independent share source was found. |
| Pricing power | moderate The FY2025 10-K shows prices being raised and sticking, and in the same breath shows what caps them. The results table puts gross margin at 36% of net sales in 2025 against 33% in 2024, and MD&A attributes the three-point gain to 'higher volume and the impact of actions taken by management to improve profitability, including raising prices, reducing costs and increasing productivity.' Display is the cleanest case: after resetting its core rate from 107 to 120 Japanese yen to the dollar, 'we implemented pricing actions in the second half of 2024', and 'The effects of the price increases on slightly higher volumes in 2025, compared to the prior period, substantially offset the impact of resetting the core rate.' The ceiling is disclosed in the same document: Optical Communications and Display are 'subject to pricing pressure', concentrated customers 'may possess substantial leverage in negotiating contractual obligations', and a risk factor warns that 'Increasing our prices to our customers may cause certain of our customers to push out, cancel or refrain from purchasing our products'. Price that holds on the back of rising volume, against customers that concentrated, is moderate rather than strong. | moderate Mixed. Gross profit has stayed in proportion through the cycle - the 10-K’s income statement shows $265,814 thousand on revenue of $467,641 thousand in 2025 - and the Q2 2026 release (https://www.sec.gov/Archives/edgar/data/0001288469/000128846926000050/a06302026exhibit991.htm) reports GAAP gross margin of 57.8% against 56.5% a year earlier, guiding Q3 to 57.0%-60.0%. But the 10-K says “From time to time, we have reduced the average unit price of our products due to competitive pricing pressures, new product introductions by us or our competitors, and for other reasons, and we expect that we will have to do so again in the future”, that under some distributor agreements “we provide protection for reductions in selling prices of the distributors' inventory”, and in optical DSPs it entered as the lower-priced challenger. | moderate The FTC complaint alleges pricing power in large tractors and combines, "shown directly through Deere's ability to raise prices, reduce output, and degrade quality in those markets", and says Deere's dealers "charge supracompetitive prices for restricted repairs". The reported numbers show a cyclical business: the third-party data site stockanalysis.com (https://stockanalysis.com/stocks/de/financials/) shows gross margin of 30.63% in fiscal 2023, 29.50% in fiscal 2024, 26.96% in fiscal 2025 and 25.18% for the twelve months to August 2026, and stored fundamentals from the 10-K show net income of $10,166 million (fiscal 2023), $7,100 million (fiscal 2024) and $5,027 million (fiscal 2025). Item 1A of the FY2025 10-K says Deere competes on "product performance, innovation, quality, distribution, sustainability, customer service, and price", that "Aggressive pricing or other strategies of competitors" or a failure "to price products competitively" hurt results, and that results suffer "if our customers are unwilling to accept price increases for our products". Alleged pricing power that still leaves margins falling with farm demand is moderate, not strong. |
| Summary | Corning is a materials company whose defence is a set of manufacturing processes it invented and then papered over with patents, and the FY2025 10-K is unusually explicit about where that defence holds and where it does not. It holds in Display, the one place the filing makes an outright rank claim - 'We are the largest worldwide producer of glass substrates for flat panel displays' - against only two named principal competitors, AGC Inc. and Nippon Electric Glass. The stated reason is process: a fusion process Corning invented, which it says 'is scalable and we believe it is the most cost-effective process for producing large size substrates', protected by patents and 'proprietary trade secrets'. It holds more loosely in Optical Communications, where the company claims 'a leadership position' and grounds it in 'large-scale manufacturing experience, fiber process, technology leadership and intellectual property', with 4,121 worldwide patents in that segment alone - but names Amphenol, Fujikura and America Fujikura, Sumitomo and Prysmian Group as principal competitors and says the landscape's 'industry consolidation, pricing pressure and competition for the innovation of new products' are 'likely to persist'. Those two lines carry the company: the filing puts Optical Communications at 38% of total segment net sales in 2025 and Display at 23%, and the segment table gives them $1,048 million and $993 million respectively of the $2,747 million of reportable-segment net income. Outside them the language weakens fast: Automotive claims 'a strong market position' against a single undivided list - 'Our principal competitors include NGK Insulators, Ltd., Ibiden Co., Ltd., AGC Inc. and LENS.'; Specialty Materials rests on capabilities and 'Brand recognition and loyalty, through well-known trademarks' against Schott, AGC, Nippon Electric Glass, Heraeus and JENOPTIK; and Life Sciences, at 6% of segment net sales and $61 million of segment net income on $972 million of sales, competes with Thermo Fisher Scientific, Danaher, Avantor and others while also facing 'competition from large distributors that have pursued backward integration or introduced private label products'. The demand side is currently the strongest part of the story rather than the moat: 2025 optical segment net sales rose 35% to $6,274 million, which the 10-K attributes to 'continued growth in our Enterprise business driven by strong demand for our Generative AI products, and in our Carrier business, driven by demand for datacenter interconnect products and fiber-to-the-home products'. That is a customer capex wave - the risk factors name 'fluctuations in telecommunication and hyperscale data center capital spending' as a risk to the very same business - landing on segments the company itself says are subject to pricing pressure, which is the honest reason this profile stops at narrow: Corning has a defended process franchise in glass and a strong but contested one in fiber, wrapped in segments where the filing claims no structural barrier at all. | MaxLinear is a fabless designer of RF, analog and mixed-signal communications SoCs whose core skill, per its FY2025 10-K, is combining broadband RF and analog front ends with digital signal processing in standard CMOS. It sells into broadband access (cable, fiber PON and DSL gateways - approximately 44% of 2025 net revenue), home connectivity (Wi-Fi, MoCA, G.hn and Ethernet), wired and wireless infrastructure including optical data-center DSPs, and industrial and multi-market interface and power products. After a downturn that took revenue from $693,263 thousand in 2023 to $360,528 thousand in 2024, the AI optical ramp is turning it around: the Q2 2026 release reports revenue of $168,847 thousand, up 55% year over year, with the infrastructure business up 145% on the Keystone PAM4 DSP ramp for 800G, and management raised its 2026 optical data-center revenue outlook to $210 million-$230 million on the call. The moat question is whether that growth rests on anything durable. In optical DSPs MaxLinear entered as a lower-priced second source to Marvell; elsewhere it competes with Broadcom, Qualcomm, Realtek and MediaTek, which can integrate the functions it sells; customers are concentrated; and the 10-K still carries the Silicon Motion arbitration over its terminated merger, whose outcome it says it cannot predict. On this record MaxLinear is a technically capable challenger without a moat. | Deere makes agricultural, turf, construction, forestry and roadbuilding equipment and finances it through John Deere Financial. Per its FY2025 Form 10-K, Production & Precision Agriculture generated $17,311 million of net sales (45% of equipment operations net sales), Small Agriculture & Turf $10,224 million (26%) and Construction & Forestry $11,382 million (29%), within net sales and revenues of $45,684 million. The core of the moat is large farm machinery. The FTC's January 2025 complaint calls Deere "the largest manufacturer of agricultural equipment in the United States" and alleges a dominant share of U.S. large tractor and combine sales, substantial barriers to entry, and significant costs to switch away from a Deere fleet, including losing machine data. The 10-K adds brand recognition, about 2,050 U.S. and Canadian dealer locations, proprietary parts and the Operations Center data platform. The same structure is under legal attack: the FTC with several states, and a separate multidistrict class action, allege that Deere unlawfully restrained the market for repairing its own farm equipment by limiting repair resources, including its fully functional Service ADVISOR tool, to its authorised dealers. On 2026-07-08 the FTC and Illinois, Arizona, Michigan, Minnesota and Wisconsin announced a settlement (https://www.ftc.gov/news-events/news/press-releases/2026/07/ftc-states-secure-settlement-deere-company-advancing-farmers-right-repair): a stipulated order, which has the force of law once the District Court approves it, requiring Deere for 10 years to make available to farmers and independent repair providers "repair resources equivalent to those Deere now makes available to Deere dealers". Item 1A also reports "slower than expected customer adoption of some of our precision technology solutions, and SaaS subscription services". Earnings are cyclical: the third-party data site stockanalysis.com shows gross margin falling from 30.63% in fiscal 2023 to 26.96% in fiscal 2025, and the 10-K reports PPA backlog down to about $4.0 billion from $5.2 billion as "demand has declined". An alleged dominant, high-barrier large-ag franchise, with repair-access litigation as the main threat to its aftermarket profits, supports a narrow moat. The dominance rests on a plaintiff's unproven allegations and covers one segment, and construction and forestry is a contested second leg. |
| Chain position | Corning sits a layer beneath the AI build-out, supplying the glass and fiber rather than the compute. The FY2025 10-K describes 'optical fiber, cable and connectivity solutions for advanced communications networks, such as fiber to the home and data centers, enabling artificial intelligence', and says 'the rapid acceleration of artificial intelligence ("AI") is driving strong demand for fiber and connectivity products inside and between data centers', citing purpose-built parts such as the SMF-28e Contour fiber, 'a 40% smaller fiber', and the Contour Flow Cable 'which can fit double the fiber into the same cable diameter'. It also sells into chipmaking, through HPFS Fused Silica, ULE Ultra-Low Expansion Glass and the EXTREME ULE Glass introduced in 2024 to 'support chip manufacturers in meeting the rapidly growing demand for advanced and intelligent technologies'. The exposure is already in the numbers: Optical Communications net sales rose 35% to $6,274 million in 2025, which the filing attributes first to 'continued growth in our Enterprise business driven by strong demand for our Generative AI products'. | MaxLinear sells chips, much of it through Asian distributors, ODMs and module makers - products shipped to Asia were 82% of 2025 net revenue, including 49% to Hong Kong - that build cable modems, PON terminals, Wi-Fi gateways, base-station radios and optical transceivers for operators and hyperscale data centers. In the AI chain it sits beside the optical-module makers as a DSP supplier, competing with Marvell and Broadcom and, at vertically integrated module makers, with internally supplied components. | An AI adopter, not an AI vendor: Item 1A of the FY2025 10-K says Deere uses "automation software, digital tools, applications, and analytics on the S7 Series Combines and our See & Spray targeted spraying solution", maintains the Operations Center data platform, and leverages generative AI in its business processes, and warns that falling behind competitors' AI advances could hurt its competitive position. |
