Moat rating narrow

The FY2025 10-K shows a real moat — 3.58 billion Family daily active people (December 2025 average, +7% YoY) and a 52% Family of Apps operating margin — but the same filing qualifies its durability on three fronts it discloses itself: it says "We face significant competition in every aspect of our business"; it names "competitive products and services, such as TikTok, that have reduced some users' engagement with our products and services"; and it discloses that since 2020 it has been "subject to a lawsuit by the FTC alleging that we violated antitrust laws" that "seeks ... divestiture or reconstruction of Instagram and WhatsApp." A moat a regulator is actively litigating to break up, and whose ad targeting depends on iOS/Android policies Meta does not set, reads narrow rather than wide.

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.

Nova is gaining share and earning steady margins, but in a market another vendor dominates. On the Q1 2026 call (2026-05-14, https://www.investing.com/news/transcripts/earnings-call-transcript-nova-semiconductors-beats-q1-2026-forecasts-stock-rises-93CH-4688858), the CEO said 'The latest Gartner market share report' shows 'an additional 400 basis points share gain in Film SIMS and critical dimension metrology', the 'second consecutive year of significant share growth, cementing Nova's position as this market's second-largest vendor'. The 2025 20-F (filed 2026-02-17) says Nova's product revenues grew at a CAGR of approximately 27.5% over 2020-2025, while Gartner estimates the process-control sector's CAGR at approximately 16.0%. Gross margin was 57.4% in 2025 and 57.6% in 2024. But the leader is KLA: Castellano of The Information Network (2025-09-10) writes that his non-metal thin film share table shows how KLA 'has entrenched its dominance' and how Nova 'has built a steady secondary position'. The 20-F also warns that 'a number of patents which relate to our main-stream products have already expired or are expected to expire in the coming years', which 'may add significant competition'. One customer took 23% of 2025 revenue and China 33%. Durable but second-place, so narrow.

Moat type network effects

The 10-K Competition section describes a three-sided network in Meta's own words: it competes "to attract, engage, and retain people who use our products, to attract and retain businesses that use our free or paid business and advertising services, and to attract and retain developers who build compelling applications that integrate with our products," and elsewhere cites "the scale of our user, advertiser, and developer base." The same filing rules out an IP-based moat: "We do not believe that our proprietary technology is dependent on any single patent or copyright or groups of related patents or copyrights."

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 20-F grounds Nova's position in measurement technology and know-how. Its patents cover optical measurement, integrated process-control concepts, X-ray measurement systems and chemical metrology, and it says 'Our in-house know-how is an important element of our intellectual property', adding that 'duplication of this coordination by competitors or individuals seeking to copy our products would be difficult' and that 'most of the core technology operating on our systems is not exposed to a user or to our competitors'. R&D staff numbered about 682, approximately 163 with Ph.D.s. Switching friction is real too: the 20-F says that once a manufacturer selects a vendor's equipment it 'generally relies upon that equipment for the specific production line application and frequently will attempt to consolidate its other capital equipment requirements with the same vendor'. But Nova is the share gainer against an incumbent, which points to technology rather than lock-in as the primary source. Patent expiries on main-stream products are a stated weakness.

Leadership co leader

Top-tier but shared: the 10-K reports 3.58 billion Family daily active people and $196.18 billion of 2025 advertising revenue, yet also states that TikTok has "reduced some users' engagement," that "each of Apple and Google have integrated competitive products with iOS and Android," and that Meta competes "with companies in the development and application of AI, particularly with respect to the development of frontier AI models."

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.

The share evidence puts Nova second. On the Q1 2026 call the CEO said the latest Gartner market share report cements Nova's 'position as this market's second-largest vendor' in film and critical dimension metrology. That ranking comes from Gartner but reaches us through Nova's own call. Castellano (The Information Network, 2025-09-10, https://drrobertcastellano.substack.com/p/onto-innovations-strategic-drift) independently writes that his non-metal thin film share table shows how KLA 'has entrenched its dominance' and how Nova 'has built a steady secondary position'. Nova is stronger in sub-segments: SemiAnalysis (2022-09-06) writes that Nova has 'a high share in integrated optical critical dimension (OCD) inspection tools and materials metrology tools', though 'little success outside these sub-segments'.

Pricing power strong

Ad-auction pricing, not list prices: the 10-K reports "the average price per ad increased by 9%" in 2025 after "an increase of 10% in 2024," driven by "an increase in advertising demand," alongside worldwide ARPP of $57.03 (+15%) and a 52% Family of Apps operating margin. The filing notes the gain was "partially offset by a higher number of ad impressions delivered ... in products, such as Reels, that monetize at lower rates."

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.

Gross margin was 57.4% in 2025 and 57.6% in 2024 (Q4 2025 release), 57.7% in Q1 2026 and 56.5% in Q2 2026 (Q2 2026 release, https://www.novami.com/investors/press-releases/nova-reports-record-second-quarter-2026-financial-results/). The 20-F credits the shift to selling directly to chipmakers with improving 'our products gross margins and net profitability'. Buyers are concentrated: the five largest customers took 51% of 2025 revenue, with Customer A at 23%, and the 20-F warns that dependence on 'few process control product lines' exposes Nova to anything 'adversely affecting the pricing' of those lines.

Summary

Meta's advantage is the size of the user-advertiser-developer network it monetizes, not proprietary technology: 3.58 billion daily active people across the Family of Apps produced $196.18 billion of 2025 advertising revenue at a 52% segment operating margin, and the 10-K attributes 2025's 9% rise in average price per ad to "an increase in advertising demand, which we believe is mostly due to ongoing improvements to our ad performance from our ad targeting and measurement tools." The filing is equally explicit about what limits that network: TikTok has "reduced some users' engagement," Apple's iOS changes "limit our ability ... to target and measure ads effectively," the April 2025 European Commission decision against its "subscription for no ads" model pushed EU users onto less personalized ads that are "less relevant and effective," and the FTC is seeking divestiture of Instagram and WhatsApp. Reality Labs, the intended next platform, lost $19.19 billion in 2025 on $2.21 billion of revenue and is expected "to continue to operate at a loss for the foreseeable future."

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.

Nova makes metrology systems that measure dimensions, films, materials and chemistry during chip manufacturing. Its 20-F groups the portfolio as integrated and standalone dimensional (optical CD) metrology, materials metrology (VeraFlex XPS/XRF, Metrion in-line SIMS, Elipson Raman), chemical metrology for plating baths (Ancolyzer, AncoScene, DMR, from the 2022 ancosys acquisition), and modeling software. The January 2025 Sentronics acquisition added modular dimensional metrology for wafer-level packaging. Nova sells 'substantially all' its products directly to chipmakers and serves 'all leading manufacturers in the logic, foundry, memory and packaging sectors'. 2025 revenue was a record $880.6 million, up 31%, and Q2 2026 revenue a record $255.0 million. The Q2 2026 release credits 'continued market share gains' and record revenue from advanced logic and advanced packaging. The 20-F names Onto Innovation and KLA as its main competitors, with process-equipment makers developing in-situ sensors and 'the recent emergence of local competitors in China'. On the Q1 2026 call (https://www.marketbeat.com/earnings/reports/2026-5-14-nova-measuring-instruments-ltd-stock/), the CEO said Nova is 'seeing emerging XPS and material metrology competition', including from 'a local vendor in China'. The exposures are concentration (the five largest customers were 51% of 2025 revenue, one of them 23%), China (33% of 2025 revenue) and patent expiries on main-stream products.

Chain position

Demand-side anchor of the AI build-out: the 10-K reports $72.22 billion of 2025 capital expenditures and says Meta has "designed and built our own data centers and key portions of our technical infrastructure," funded entirely by the advertising business.

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'.

Upstream metrology supplier to logic, foundry, memory and packaging chipmakers, selling directly to manufacturers. Its integrated systems are built into process tools. China was 33%, Taiwan 29% and Korea 16% of 2025 revenue.
