PSMC lost money through the last mature-node downturn and then sold its newest fab. Its 2025 annual report (printed 2026-02-24) records revenue of NT$46.7 billion and 'a net loss after tax of NT$7.8 billion for the year'. Gross profit swung from NT$525,425 thousand in 2024 to a loss of NT$1,536,997 thousand in 2025, 'primarily attributable to an increase in gross loss from operations at the Tongluo Fab'. The report says 'good performance was difficult both in pricing and capacity utilization rates for mature-node wafer foundry services'. PSMC then agreed to sell the Tongluo site and facilities, excluding manufacturing equipment, to Micron. The Register (2026-01-20) reports total cash consideration of US$1.8 billion, against PSMC's earlier statement that it had invested more than NT$300 billion (US$9.5 billion) in the facility. Profits have since recovered: Q2 2026 net income was NT$3,291 million, against a NT$3,334 million loss a year earlier, per the company's September 2026 presentation. The cited sources tie that recovery to memory and wafer price increases, not to a lasting edge.

narrow

Semtech’s FY2026 10-K (fiscal year ended January 25, 2026) supports a narrow moat and no more. On the durable side, it owns the LoRa® radio franchise - “our LoRa® devices and wireless radio frequency technology” - which IoT Analytics’ LPWAN Market 2024 release (https://iot-analytics.com/wp-content/uploads/2024/03/INSIGHTS-RELEASE-LPWAN-Market-2024.pdf) ranks first outside China at 41% of LPWAN connections, and it argues that scarce analog talent “has historically made it more difficult for new suppliers in the analog market to quickly develop products and gain significant market share.” On the limiting side, the same filing says its patents do not “create definitive competitive barriers to entry”, that average selling prices “have historically decreased rapidly”, that some customers “can stop incorporating our products into their own products with limited notice to us and suffer little or no penalty”, and that customers in China (including Hong Kong) were 47% of fiscal 2026 net sales. The record is uneven: its income statement shows gross profit of $296,250 thousand on net sales of $868,758 thousand in fiscal 2024, $456,528 thousand on $909,287 thousand in fiscal 2025 and $542,144 thousand on $1,049,975 thousand in fiscal 2026, and the 10-K says difficulties “have adversely impacted” its ability to realise the benefits of the Sierra Wireless acquisition.

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.

Moat type none

The cited evidence supports none of the candidate moat sources. Cost: the annual report says its 12-inch aluminum-interconnect dies cost 30% less than 8-inch dies at the same node, yet the company still posted a 2025 gross loss. Switching costs: the report names 'the price and capacity competition of china wafer foundries' as an unfavorable factor. TrendForce (2026-05-07) says customers in HV processes and CIS applications are 'increasingly turning to Chinese foundries for more stable pricing and capacity availability'. Niche memory: PSMC's September 2026 presentation claims shares of 71% in DRAM (≤1Gb) and 74% in pseudo SRAM (≤256Mb), citing 'Company data, Omdia, TrendForce'. No independent source confirming those shares was found.

intangibles ip

The defensible assets the 10-K describes are intellectual: the LoRa® radio technology, analog and mixed-signal design expertise - “The development of IP and the resulting proprietary products is a critical success factor for us” - and 303 U.S. and 541 foreign patents. The filing itself discounts the patent part (“we do not believe they create definitive competitive barriers to entry”), which leaves the moat in proprietary technology and scarce design know-how rather than in scale or lock-in: Semtech outsources most manufacturing, sold 74% of fiscal 2026 net sales through independent distributors, and its customer agreements “do not require them to purchase a minimum quantity of our products”.

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.

Leadership at parity

PSMC sits in a cluster of similar-sized foundries rather than leading any. TrendForce ranks it tenth in 1Q26 (foundry-only revenue of $386 million, a 0.8% share) and tenth in 2Q26 ($432 million). It is just behind Nexchip ($447 million), VIS ($451 million) and Tower ($460 million). Its own annual report puts it 'among the top ten wafer foundry companies worldwide, with a market share of approximately 1%'.

fast follower

LoRa, the technology Semtech owns, leads outside China; elsewhere Semtech is contesting the front rank. IoT Analytics’ March 21, 2024 release states “When excluding all LPWAN data from China, LoRa has the leading share of global LPWAN connections at 41%—more than double NB-IoT’s share”, though “Globally, NB-IoT has the largest share of LPWAN connections at approximately 54%” and “LoRa’s share of LPWAN connections is decreasing”. In data-center optics, management said on the fiscal Q2 2027 call (TradingKey machine transcript, https://www.tradingkey.com/news/transcripts/262131465-tradingkey) that at “800 gig, we had the market share about 18%. So over the 2 years, we have grown the market share well over 50% for 800 gig”, a company figure; an independent September 2024 newsletter (Deep Fundamental) had instead named Marvell and MACOM “the dominant players” in drivers and TIAs and said Semtech “has struggled to keep pace since the transition to 200G”. A third-party lead measured at the technology level rather than as Semtech’s own share, a company-reported share that the only independent view contradicts, and no ranking for its other lines do not evidence co-leadership, so the band is fast follower.

co leader

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.

Pricing power weak

PSMC is raising prices now, but on a memory shortage after a year of gross losses. The 2025 annual report shows a gross loss of NT$1,536,997 thousand. TrendForce (2026-04-22, citing Liberty Times) reports that PSMC 'sharply raised DRAM foundry pricing in March', raised NAND wafer start prices in April, and lifted 8-inch prices 'by an average of around 10% month over month since March'. President Martin Chu said logic price increases 'are likely to remain far more moderate than the sharp hikes seen in memory'. He tied the memory upswing to 'a structural supply deficit through the second half of 2026', which is a cyclical driver.

moderate

The 10-K describes a market where prices fall: “In the past, we have reduced the average selling prices of our products in anticipation of future competitive pricing pressures”, and Semtech’s products “are typically differentiated in performance but are priced competitively”. Margins have nonetheless climbed with the data-center mix: the fiscal Q2 2027 release (https://www.sec.gov/Archives/edgar/data/0000088941/000008894126000028/smtc-07262026x8k991.htm) reports GAAP gross margin of 53.8% against 52.1% a year earlier and guides fiscal Q3 adjusted gross margin to 58.3% +/- 100 bps, or 63.9% excluding the business held for sale. The release does not separate price from mix.

weak

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.

Summary

PSMC is a Taiwanese foundry with two 8-inch and three 12-inch fabs in Hsinchu and Zhunan. It has three businesses: memory foundry (niche DRAM, SLC NAND and NOR flash), specialty logic (PMICs, power discretes, high-voltage display drivers, CMOS image sensors) and a newer '3D AI foundry' (wafer-on-wafer stacking, interposers, silicon capacitors and HBM post-wafer finishing). In Q2 2026, memory was 52% of revenue, logic 42.6% and 3D AI 5.4%, per its September 2026 presentation. 2025 was a loss year. Revenue rose 4% to NT$46.7 billion, but the company lost NT$7.8 billion as the new Tongluo fab failed to reach scale. 2026 has turned on prices. Q2 2026 revenue was NT$17,291 million, up 53% YoY, with foundry utilization of 87% against 75% a year earlier. TrendForce ranks PSMC tenth in 2Q26 with $432 million, noting that 'overall shipments increased only modestly' and that price increases drove the growth. The strategy is changing. PSMC sold the Tongluo site to Micron, and will provide HBM post-wafer finishing for Micron, with mass production expected in Q4 2027 (TrendForce, 2026-04-22). Its silicon capacitors are expected in Intel's EMIB packaging, according to PSMC. The verdict is no moat. PSMC is a mature-node foundry whose 2026 profits reflect a memory-price cycle after a loss-making 2025, and Chinese foundries compete with it on price.

Semtech is an analog and mixed-signal chipmaker being reshaped around two franchises. The first is AI data-center connectivity in its Signal Integrity segment - FiberEdge TIAs and drivers for optical transceivers and CopperEdge redrivers for active copper cables - whose net sales the FY2026 10-K reports at $322,608 thousand in fiscal 2026 against $177,033 thousand in fiscal 2024; the March 2026 HieFo acquisition added foundries that make devices for data-center interconnects. The second is LoRa, the long-range, low-power radio that IoT Analytics ranks as the leading LPWAN technology outside China. Around them sit protection devices, sensing and power products, and the IoT Systems business inherited from Sierra Wireless, whose cellular-module unit Semtech has agreed to sell to Compal Electronics for US$62 million (ABI Research, September 9, 2026, https://www.abiresearch.com/market-research/insight/7788486-compal-electronics-takes-semtechs-mantle-t). Momentum is strong: the fiscal Q2 2027 release reports record net sales of $341.9 million, up 33% year over year, and management said data-center revenue hit a record $100 million in the quarter. But the 10-K is frank about limits - rapid ASP erosion, customers that can drop its parts with little notice, 47% of sales to China, competitors that are “much larger and better resourced than we are”, and patents that do not bar entry. Proprietary technology in two growing niches, rather than a locked-in customer base, makes the moat narrow.

X-energy's defensible assets today are regulatory and intellectual, not commercial. NRC Special Nuclear Material Licence SNM-7007, issued 13 February 2026 for a 40-year licence period, authorises HALEU fuel manufacture at Oak Ridge, and the company's own prospectus calls it the first-ever Category II nuclear fuel facility licensed in the United States; the Long Mott construction permit application for four Xe-100 reactors has reached its uncontested mandatory NRC hearing, scheduled for 22 September 2026. Neither has yet produced a reactor or a commercial fuel pebble: the prospectus expects TX-1 to be completed in the first half of 2028, and the 10-Q describes present revenue as derived from cost-share agreements such as the DOE ARDP. The HALEU feedstock the fuel depends on is a live dependency rather than a settled advantage — the prospectus states HALEU enrichment services are available only in limited quantities globally and that customers procure the feedstock, and the 10-Q discloses a definitive enrichment agreement with Centrus Energy announced 6 August 2026 under a phased approach with prepayments by X-energy to support Centrus's domestic capacity programme.

Chain position

Upstream foundry for fabless memory and specialty-logic designers. Fabless customers were 90% of Q2 2026 sales. It also provides silicon capacitors, interposers and HBM post-wafer finishing to AI packaging supply chains.

Semtech sells mostly through independent distributors (74% of fiscal 2026 net sales) to OEMs. In AI data centers its FiberEdge and CopperEdge parts go into the optical transceivers and active copper cables that module and cable makers build, and the 10-K says hyperscale cloud providers “are generally our indirect customers”. Two customers took 14% and 11% of fiscal 2026 net sales, and customers in China (including Hong Kong) 47%.

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.
