The filing's own words support a narrow moat. Auctions run 'at vast scale and at microsecond-level speeds,' revenue is earned only 'when our advertisers achieve their return on advertising spend targets,' and FY2025 adjusted EBITDA margin was 82.3%. What limits the width: clients 'are not required to enter into long-term agreements' and 'Substantially all of the Company's contracts with customers are cancelable at any time'; the solutions 'primarily operate in the mobile app ecosystem and specifically mobile gaming'; and distribution runs through 'the Apple App Store, the Google Play Store, and Meta' while AppLovin relies 'in part on IDFA.'

The FY2025 20-F Competition section cuts both ways: UMC calls itself "one of the world's largest independent semiconductor foundries" with production capacity "currently among the largest of all semiconductor foundries in the world" and says it believes it competes favorably with competitors on each principal element of foundry competition, yet in the same section concedes that "[s]ome of our competitors have substantially greater production, financial, research and development and marketing resources than we have" and that "several new dedicated foundries have commenced operations and compete directly with us," whose entry is "likely to initiate a trend of competitive pricing and create potential overcapacity in legacy technology" that "may erode our profit margins." A real but bounded advantage, not a durable wide one.

Real but unbuilt. The Q2 2026 10-Q shows the moat resting on regulatory standing rather than delivered product: the NRC completed the Environmental Assessment for the Dow Long Mott construction permit application on 18 May 2026 with a Finding of No Significant Impact, yet no Xe-100 has been constructed or operated and two counterparties supplied nearly all income, with the U.S. Government at 90.3% and Dow at 4.4% of total revenue and grant income for the three months ended 30 June 2026.

Network effects, with a caveat. The 10-K states the loop: as more advertisers use the solutions 'we gain access to more data regarding users and user engagement,' 'further strengthening our scaled distribution,' and 'As our distribution grows, we gain better insights for Axon AI.' The mechanism is two-sided matching of advertiser demand to publisher supply, though much of the force comes from data-and-learning scale. It is not switching costs, since contracts are 'cancelable at any time,' nor intangibles or IP, since 'there can be no assurance that we will adequately protect our intellectual property or that it will provide any competitive advantage.'

The 20-F states plainly that "Our success depends on our ability to obtain patents, licenses and other intellectual property (IP) rights covering our production processes and activities," and reports more than 16,700 patents worldwide as of December 31, 2025, of which more than 7,490 are in the U.S., 623 domestic and foreign patents granted in 2025 alone, NT$17,725 million of R&D (7.5% of operating revenues) and 1,591 R&D professionals. The Competition section names where UMC believes it wins: it competes favorably "particularly [on] our technical competence and research and development capabilities." The proprietary specialty-process library, not scale or a network, is the cited source of the advantage.

The IPO prospectus describes an 'intellectual property-driven business model': revenue is to come from technology fees for licensing the proprietary Xe-100 design plus proprietary TRISO-X fuel, and the company states it will not construct, own or operate the power plants. The durable assets are therefore patents and NRC licences, not plant, installed base or scale.

The filing discloses no share of any market, names 'Meta, Google, Amazon, and Unity Software' as competitors, and concedes rivals 'may have greater resources' and 'better technological or data analytics capabilities, or stronger brands or competitive positions in certain product segments.' Its one positional statement is parity language: 'We believe we compete favorably with respect to these factors.' Two unquantified points cut upward: Meta and Google are also clients, and MAX is called 'the preferred in-app bidding solution for many publishers worldwide.'

UMC describes a deliberate follow strategy in the 20-F: it intends "to avoid investments in technologies that do not present commercial potential for volume production" and believes "it is beneficial to defer investment in premature equipment needed to claim the earliest advanced technology and instead to purchase more advanced and less expensive versions of such equipment from vendors who design this equipment based on pre-production lessons learned from the earliest technology." The node ladder bears this out: the most advanced process in production in 2025 is Fab 12A's 0.014 micron, wafers at 14 nanometers and under rounded to 0.0% of wafer sales in each of 2023, 2024 and 2025, and the next rung — UMC's own 12nm FinFET process, which Intel replicated in 2025 "based on our electrical design rules and UMC-verified process" for manufacture at its Arizona fab — is only "expected to begin in 2027."

The prospectus records X-energy as one of two awardees under the DOE Advanced Reactor Demonstration Program, and it holds the Oak Ridge HALEU fuel-fabrication licence; but it is not the NRC design-approval leader — the NRC issued a standard design approval to NuScale for the US460 small modular reactor, published at 90 FR / Federal Register document 2025-10123 on 4 June 2025, while the Xe-100 is being licensed indirectly through a customer's Part 50 construction permit and holds no design certification or approval of its own.

Strong, with the mechanism shown. The 10-K states that 'Advertisers are charged dynamically based on their campaign goals , rather than a simple fixed price per impression or per action.' Growth composition is the evidence: FY2025 revenue +70% with 'the volume of installations increased 3% and net revenue per installation increased 72%'; H1 2026 +56% with per-installation revenue +75% against 'a decrease in the volume of installations of 10%.' Adjusted EBITDA margin was 82.3% in FY2025 and 84.2% in H1 2026, though payment is performance-contingent and contracts cancel at will.

The 20-F claims no premium — "our current level of pricing is comparable to that of other leading foundries in each respective geometry" — and reports that 2025 average selling price declined 5.4%, driving gross margin down from 32.6% in 2024 to 29.0% in 2025 even as 12-inch-equivalent wafer shipments rose from 3,446 thousand to 3,870 thousand and average capacity utilization improved from 68.7% to 75.2%. It also notes that "[p]rices for wafers of a given level of technology generally decline over the processing technology life cycle."

Nothing has been priced in a market yet. The prospectus states the Xe-100 technology fee is a benchmarking assumption to be 'negotiated on a case by case basis' with no assurance customers will accept the proposed structure, and that Amazon holds first-priority manufacturing queue slots across 2031-2039, a right of first refusal and most-favoured pricing; the 10-Q records a 2025 warrant issued to a related-party customer with a $162.7 million grant-date fair value accounted for as consideration payable to a customer, i.e. a reduction of the transaction price.

Demand-side AI ad platform: it monetizes third-party mobile-game publishers' inventory and sells outcomes to advertisers, so it sits downstream of Apple/Google app distribution and Apple's IDFA identifier layer and upstream of publisher monetization. Meta and Google are simultaneously named competitors and disclosed clients. Single reportable segment after the June 2025 Apps divestiture.

Mature- and specialty-node wafer supplier: 2025 wafer sales were 41.4% communication, 30.6% consumer and 11.6% computer, with the AI tie indirect — 2.5D silicon interposers with deep-trench capacitors shipped to major customers for HPC, cloud computing and LLM applications.

Upstream supplier of reactor technology and TRISO fuel to industrial-heat and data-centre power buyers; it licenses the design and fabricates the fuel rather than owning or operating the plants.
