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.

Cipher (renamed Cipher Digital Inc. on 20 February 2026) holds signed, credit-supported leases but has not yet shown that they amount to a durable advantage. Its 2025 Form 10-K (filed 2026-02-24) says "Through the end of 2025, our revenue has been derived from mining bitcoin". Its Q2 2026 business update (2026-08-04, Exhibit 99.1, https://www.sec.gov/Archives/edgar/data/1819989/000181998926000038/q226_earningsxprxdraftxvf.htm) reported "Q2 2026 Revenue of $25 million", and its first HPC rent began only in August 2026 at Black Pearl. The 10-K's own risk factors describe a contested market. They say "There has been an increasing number of businesses constructing HPC data centers, which has resulted in increasing competition and pricing pressure that may cause us to reduce our pricing in order to remain competitive", that "our data centers are single-tenant properties", and that lessees "will have the right to terminate the lease if there are significant delays in the completion of construction". At Barber Lake, where the 10-K targeted Phase I delivery "by September 30, 2026", a September 2026 amendment, made "In connection with change orders and the continued evolution of tenant requirements", moved data-hall deliveries to the fourth quarter of 2026 through the first quarter of 2027. Under it, Cipher "will bear the first $359.3 million of costs in excess of the initial budgeted amount" (2026-09-25). There is real counter-evidence: a 15-year Amazon lease, a Google-backstopped Fluidstack lease whose contracted life a "leading AI lab" extended to 20 years, and a third lease with an investment-grade hyperscale tenant. Until that capacity is delivered and paying rent, though, a moat is not shown, so the band is none.

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.

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.

No moat source is demonstrated yet. Switching costs are the most likely candidate, since the leases are long (15 years at Black Pearl; Barber Lake now a 20-year contracted life) and each site has a single tenant. But the 10-K says tenant guarantees "will only be effective after rent commencement under such leases and are subject to certain limitations", and by August 2026 rent had begun at only one site. The advantages the 10-K claims are the company's own. It speaks of "industry-leading expertise in originating and securing industrial-scale, greenfield data center sites" and of securing West Texas land "on more favorable terms than in more established data center markets". The same document says "there is significant competition for power capacity and energized facilities". Intellectual property is modest: "four granted United States patents and one issued patent in Taiwan". With 66 full-time employees, Cipher has no scale advantage over the competitors it names: CoreWeave, Digital Realty, Equinix, Vantage Data Centers and Aligned Data Centers.

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.

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."

No independent share or rank was found. The 10-K names CoreWeave, Digital Realty, Equinix, Vantage Data Centers and Aligned Data Centers as competitors, along with miners that have "signed leases with hyperscalers and HPC tenants": Hut 8, IREN, TeraWulf, Core Scientific and Applied Digital. Cipher has signed hyperscale-grade tenants (Amazon; Fluidstack with a Google backstop; a third investment-grade hyperscaler) but delivered its first HPC capacity only in August 2026 (Q2 2026 update). That makes it a fast follower. Its self-description as "a leading developer, owner, and operator of industrial-scale data centers" is the company's own claim and is not counted.

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'.

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."

The 10-K says competition "has resulted in increasing competition and pricing pressure that may cause us to reduce our pricing in order to remain competitive". It adds that if customers cut usage "we may be compelled to lower our prices or risk losing a significant customer". At Barber Lake, Cipher agreed to absorb "the first $359.3 million of costs in excess of the initial budgeted amount", with the tenant reimbursing "50% of any such costs above that amount" (2026-09-25, Exhibit 99.1, https://www.sec.gov/Archives/edgar/data/1819989/000181998926000043/barberlakeleaseamendmentpr.htm). Its one input-cost edge is specific to mining: Odessa's power costs about 2.8 c/kWh under the Luminant contract, available "until at least July 2027". A landlord that concedes cost overruns to its tenants has weak pricing power.

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.

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.

Cipher develops single-tenant, powered data-centre campuses for hyperscale and AI tenants: Amazon at Black Pearl, Fluidstack (backstopped by Google) at Barber Lake, and an unnamed investment-grade hyperscaler at a third campus. Meanwhile it winds down bitcoin mining.

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.
