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.

Customers can leave easily, and the FY2025 10-K (filed 2026-02-24) says so: 'The majority of our contracts with our customers are based on our terms of service, which do not require our customers to commit to a specific contractual period, and which permit the customer to terminate their contracts or decrease usage of our products and services without advance notice.' The 10-K also reports that net dollar retention, the measure of revenue kept and grown from existing customers, 'increased from 98% in 2024 to 100% in 2025'. It says larger competitors 'have substantial competitive advantages as compared to us', among them 'the ability to bundle products together' and 'larger and more mature intellectual property portfolios'. DigitalOcean itself owned six issued patents at December 31, 2025. The developer community, free support and simple pricing described in the 10-K attract customers but do not lock them in, so the rating is none. Longer AI contracts are new. The Q2 2026 results release (2026-08-04, https://investors.digitalocean.com/news/news-details/2026/DigitalOcean-Announces-Second-Quarter-2026-Financial-Results/default.aspx) reports the 'first nine-figure annual customer commitments with leading AI-Natives, extending weighted average contract life from 1.6 years to over 3 years'. These are too recent to change the call. No independent market-share figure was found.

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.

The 10-K shows no durable source of advantage. Contracts give low switching costs, since customers can end or cut usage 'without advance notice'. Scale favours rivals: 'We compete primarily with large, diversified technology companies that focus on large enterprise customers', which the 10-K names as AWS, Azure, GCP, IBM Cloud, Alibaba Cloud and Oracle Cloud. In AI it competes with the same large companies and 'smaller more infrastructure-focused companies such as Coreweave and Lambda Labs'. It also faces 'competition with larger cloud computing companies and other consumers with respect to high demand equipment, such as GPUs'. Its intellectual property is thin: six issued patents, and 'We use open source software in our services.' The nearest thing to an intangible asset is the developer community. Hacktoberfest drew 'over 56,000 developers completing over 87,000 contributions in 2025', and the 10-K presents the community as a way to win customers rather than a barrier that keeps them.

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.

By its own account DigitalOcean is not a leader. The 10-K names AWS, Azure, GCP, IBM Cloud, Alibaba Cloud and Oracle Cloud as its primary competitors. It says larger competitors have 'greater name recognition and longer operating histories, larger sales and marketing and customer support budgets and resources'. Among 'smaller and/or niche cloud service providers' it names 'OVHcloud, Akamai (Linode), Hetzner, Vultr, and Contabo'. Its products cover the same categories as the larger clouds (virtual machines, managed Kubernetes and databases, serverless functions, GPUs and inference), packaged for smaller customers: 'Our goal is to address the core needs of our customer base instead of offering thousands of complex products and services that are more suited to large enterprise companies.' Growth is speeding up: the 2026-08-04 presentation says Q2 2026 revenue grew 29%, 'more than double a year ago'. No third-party share figure was found, and nothing cited places DigitalOcean ahead of the smaller providers or close behind the large ones, so the band is at parity rather than fast follower.

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.

Gross profit kept pace with revenue from 2023 to 2025 but fell behind in Q2 2026; the 10-Q says 'The decline in gross margin resulted from incurrence of costs for data center expansions in advance of the ramp in revenue from new data centers.' SEC XBRL data carried in TradingPilot fundamentals show gross profit of $397,497 thousand on revenue of $692,884 thousand in 2023, $465,943 thousand on $780,615 thousand in 2024, and $539,592 thousand on $901,427 thousand in 2025. The 10-Q filed 2026-08-04 shows $154,662 thousand on $281,184 thousand for Q2 2026, against $130,945 thousand on $218,700 thousand in Q2 2025. The 10-K warns that 'certain customers may demand substantial price concessions', that 'in the future we may be required to reduce our prices or develop new pricing models', and that customers 'may reduce their usage to lower-cost pricing tiers'.

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'.

Downstream cloud provider: rents CPU and NVIDIA and AMD GPU capacity (H100, H200, HGX B300; MI300X, MI350X, MI355X per the Q2 2026 presentation) from leased data centers to developers, smaller technology companies and AI-native companies.
