The 2025 annual report (English version filed with TWSE on 2026-05-08) describes a large ODM without a protected return. Revenue rose 6.95% to over NT$691.1 billion; the company's March 2026 investor deck puts 2025 gross profit at 5.3% of revenue against 5.2% in 2024, and its 2Q26 deck (2026-08-19) shows gross margin down to 4.2% from 5.1% a year earlier as revenue rose 45%. One coded customer ("a") took 50% of 2025 net sales and a second ("b") 14%. The report warns that rivals' spending is raising "both technological thresholds and price competition", which "may compress gross margins and affect market share performance". Independent data agree: DigiTimes' 1H25 ranking (via Global SMT, 2025-07-24) moved Inventec from 10th to 12th among the top 20 EMS/ODM vendors as Huaqin and Wiwynn overtook it, and a DigiTimes analysis (2025-01-27) found its 2024 net-profit rank six places below its revenue rank and its net margin at 1.5% or less since 2018, with no clear sign of improvement. No moat is claimable.

Axcelis's FY2025 10-K describes a protected but contested position. On the durable side, it says 'Axcelis and Applied Materials are the only ion implant system manufacturers with a full range of implant products'. About 3,400 Axcelis products are in use in 27 countries, and they feed an aftermarket business (CS&I) that earned $268.0 million, or 31.9% of 2025 revenue. The company holds 169 active U.S. patents and 356 active patents granted in other countries. On the limiting side, the risk factors say the ion implant segment 'includes one company with substantially greater financial, engineering, manufacturing, marketing and customer service and support resources', as well as 'several smaller companies that could provide innovative systems'. U.S. export controls 'exacerbate the risk that Chinese customers will change suppliers to non-U.S. vendors', while Kingstone Semiconductor and CETC 'continue to develop ion implanters for the Chinese domestic market'. 'None of our customers have entered into a long-term agreement requiring it to purchase our products.' Revenue fell to $839.0 million in 2025 from $1,017.9 million in 2024. A full-line position with a large installed base, against a better-resourced rival and new Chinese entrants, is a narrow moat.

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.

The candidate sources are IP and customer programmes, and neither shows up in returns. The report cites more than 17,500 patents granted worldwide as of December 2025, a top-ten place in Taiwan for invention patent applications for more than 25 consecutive years, and a "Server Liquid Cooling Patents" TOP 5 listing by DIGITIMES, and says Inventec "has long led the industry in the patent layout of liquid-cooling thermal solutions for servers"; R&D was 2.07% of 2025 revenue. Customer ties are stable ("no significant changes in the main sales customers and their sales proportions" over two years), but one customer took 50% of 2025 net sales. DigiTimes' analyst wrote (2025-01-27) that Inventec, Pegatron, Compal and Wistron all began as computer-system makers whose component businesses and degree of vertical integration can hardly match those of Chinese makers. Real engineering capability, but the 4.2% 2Q26 gross margin shows no durable barrier.

The FY2025 10-K grounds the advantage in owned implant technology rather than contractual lock-in. Its Purion implanters share 'a common platform which enables a unique combination of implant purity, precision, and productivity', and its high energy systems use 'production-proven RF Linac high energy, spot beam technology'. System assembly and testing stays in-house 'due to the high degree of expertise and intellectual property associated with the process and design'. The company holds 169 active U.S. and 356 foreign patents, though it says it is not 'substantially dependent on any single patent or any group of patents'. The installed base supports aftermarket revenue but does not lock customers in: the risk factors say customers often train 'their own staff to maintain and service' equipment and buy parts that are not patent-protected from third parties. Switching costs are therefore the weaker candidate.

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.

A mid-table member of the industry's top 20, outside the leading group. DigiTimes' 1H25 top-20 EMS/ODM ranking (via Global SMT, 2025-07-24) places Inventec 12th at an estimated US$10.8 billion, down from 10th in 1H24 and 2H24, after "Huaqin and Wiwynn each overtook Inventec"; the same report names Foxconn, Quanta, Wistron and Wiwynn as the "primary beneficiaries" of generative AI, and DigiTimes' 2025 ranking (cnyes, 2026-02-02) expects AI server and rack orders to concentrate in Foxconn, Wistron and Quanta. In notebooks, market research cited in Pegatron's 2025 annual report puts Inventec fourth of the five Taiwanese ODMs it lists, at 13.5 million units, behind Quanta's 46.73 million. 1H26 revenue rose 37% (2Q26 deck), but no cited source shows it regaining rank or joining the leading group: behind rather than at parity.

The FY2025 10-K says 'In the market for ion implantation systems, we mainly compete against Applied Materials' and that the two 'are the only ion implant system manufacturers with a full range of implant products'. It claims Axcelis 'has been a market leader in high energy ion implanters for many years' and is 'a technology leader and supplier of choice' in power devices. But its risk factors say the implant segment includes 'one company with substantially greater' resources (unnamed there; Applied Materials is the main rival it names), and it lists 'Achieve market share leadership across all served markets' as a 2026 goal rather than a current fact. No third-party market-share source was fetched, so these are the company's own claims. Which of the two full-line suppliers has the larger overall share is not established by the sources read. Because the only basis for a shared lead is the company's own description, and that description treats share leadership as a goal not yet met, the band is held at fast_follower rather than co_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.

Company investor decks show gross margin of 5.3% in 2025 and 5.2% in 2024 (2026-03-10), and 4.2% in 2Q26 against 5.1% in both 1Q26 and 2Q25, with 1H26 at 4.6% against 5.5% while revenue rose 37% (2026-08-19). The annual report warns of price competition that "may compress gross margins". DigiTimes (2025-01-27) counted Inventec among Taiwanese makers whose net margin had been 1.5% or less since 2018, with no clear sign of improvement.

The FY2025 10-K reports gross margin of 44.9% in 2025 against 44.7% in 2024. That held steady while revenue fell from $1,017.9 million to $839.0 million, but its risk factors warn that 'if we must lower prices to remain competitive without commensurate cost of goods savings, our gross margin and profitability will be adversely affected'. They also say that if suppliers raise component costs, Axcelis 'may not be able to raise the price of our products to cover all or part of the increased cost'. On the Q2 2026 call (https://www.marketbeat.com/earnings/reports/2026-8-5-axcelis-technologies-inc-stock/), management reported a non-GAAP gross margin of 42.7% (the call states its income-statement measures are non-GAAP unless noted, so it is not directly comparable with the 10-K's GAAP figures), 'slightly below our outlook of 43%', citing CS&I mix and higher than anticipated services costs.

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.

Contract designer-manufacturer of notebooks and servers for brand and cloud customers, selling into America, Europe and Asia; the annual report names Intel and AMD as CPU suppliers, AUO, BOE and INX for panels, and SK-Hynix, Samsung and Kioxia for SSDs.

A front-end wafer-fab equipment supplier to chipmakers, concentrated in Asia and in power devices. The FY2025 10-K says implanter shipments to Asian customers were 76.0% of 2025 system revenue, international sales 83.7% of total revenue, and the top ten customers 55.2% of net sales. It also says sales to Chinese customers are expected to remain significant under U.S. export-control licensing.

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'.
