Moat rating narrow

The FY2025 10-K shows RPO of $28.2 billion, up 27%; customers above $5 million of ACV at 603, 502 and 420 as of December 31 2025, 2024 and 2023; revenue of $13,278 million, up 21%; and a 98% renewal rate for three years. That rate cannot prove durability: the filing computes it excluding "changes in price or users," says it "does not reflect increased or decreased purchases," and warns "period-to-period comparison of renewal rates may not be meaningful." The company also calls its market "characterized by fragmentation, low barriers to entry." Real switching costs plus compounding large accounts support narrow; wide would need durability proof this filing lacks.

FY2026 10-K (filed 2026-03-11): differentiated platform IP — over 10,000 issued patents and pending applications as of 2026-01-31, plus a proven custom ASIC platform leveraging ultra-high-speed SerDes, silicon photonics, co-packaged optics and custom HBM — but Marvell itself calls its markets 'intensely competitive' with 'pricing pressures', notes customers 'have chosen to develop certain semiconductor products internally', and discloses two >=10% customers with the ten largest at 82% of FY2026 net revenue. Real, defensible IP in a concentrated, contestable customer base = narrow, not wide. https://www.sec.gov/Archives/edgar/data/1835632/000183563226000011/mrvl-20260131.htm

narrow

The 10-K states that "the majority of our facilities operate as “merchant” facilities without long-term power sales agreements" and that Vistra is "not guaranteed any rate of return on our capital investments". Against that, the scarcity is real: six NRC-licensed nuclear units totalling 6,448 MW, licences running 2036-2053, inside a 43,641 MW fleet, plus 20-year PPAs with AWS (1,200 MW) and Meta (2,609 MW). The 2025 gas additions - Lotus (2,600 MW, closed October 2025) and pending Cogentrix (5,500 MW) - extend the merchant gas side, not the nuclear scarcity. Only the 433 MW of uprates extends the moat asset.

Moat type switching costs

The binding force is architecture and configuration. The filing describes "a multi-instance architecture that provides each customer with a dedicated application layer and database," an ITOM product that "maintains a single record of all IT configurable items," and products built to "integrate with existing workflows rather than replace them." Once that record and its integrations are configured, replacement becomes a re-platforming program — our inference, as the filing quantifies no switching cost. Not IP: it holds "over 2,000 issued U.S. and foreign patents" but is not "materially dependent on any single patent." Not network effects.

intangibles ip

The moat rests on hard-to-replicate mixed-signal IP: the 10-K describes the custom ASIC platform built on ultra-high-speed SerDes, ARM compute, security, storage, silicon photonics and advanced packaging (die-to-die interconnects, chiplets, CPO, custom HBM), with multiple 5nm designs executed, 3nm in progress and a 2nm platform in development; a secondary switching-cost element comes from multi-year custom design wins co-developed to individual customer specifications. https://www.sec.gov/Archives/edgar/data/1835632/000183563226000011/mrvl-20260131.htm

intangibles ip

The intangibles are non-replicable regulatory assets rather than patents: six nuclear licences (Comanche Peak 2050/2053, Perry 2046, Davis-Besse 2037, Beaver Valley 2036/2047), fuel "contracted to support all our refueling needs through 2030", section 45U credits "recognizing the value of existing carbon-free nuclear power", and TXU Energy, sold "for over 20 years" and "registered and protected by trademark law". Read 45U as a floor, not moat strength: the 2025 credit was $220m against $545m in 2024, and it "provides increasing levels of support as unit revenues decline". Efficient scale does not apply.

Leadership clear leader

The call is scoped to IT service management. Apps Run The World's 2024 ITSM ranking (page dated 23 July 2025) places ServiceNow first at 44.4% share, ahead of Atlassian, BMC, GoTo and Ivanti, in an $11.4 billion market where the top ten hold 83.3%. Scale corroborates: about 8,700 customers, 29,187 employees, $13,278 million of revenue, $28.2 billion of RPO. References to "two decades partnering with enterprise customers" and process knowledge "that cannot be readily replicated" are the filing's own characterisation. Outside ITSM it is weaker: one of six Leaders in the 2025 Gartner LCAP quadrant, and tenth of ten in CRM behind Salesforce at 26.1%.

co leader

Leader in its optics niche, #2 in custom silicon: ~60% of high-end PAM4 DSP share (36kr, 2026-06-27, https://eu.36kr.com/en/p/3870758441178373) but an estimated 20-25% of custom AI ASIC design services versus Broadcom's ~70% (hashrateindex, 2026-05-13, https://hashrateindex.com/blog/design-partners-ai-asic-market-part-2/) — net, a co-leader in AI data-center connectivity/custom silicon behind Broadcom overall.

co leader

Vistra describes itself as "one of the largest producers of power in deregulated markets in the U.S." with over 230 TWh generated, "one of the largest competitive power generators in the U.S. as measured by MWh of generation capacity", "one of the largest electricity generators in the U.S.", and "one of the largest competitive residential retail electricity providers". That hedged phrasing appears four times and is the strongest claim the filing makes. The 10-K names no competitor and assigns no rank, so co-leader is the ceiling the disclosure supports.

Pricing power moderate

The filing discloses no average selling price, no net revenue retention and no pricing data, and the renewal rate is no proxy — it "does not reflect increased or decreased purchases" and excludes "changes in price or users." Revenue up 21%, the $5 million-plus cohort up about 20% annually and RPO up 27% are all consistent with expansion at flat pricing. Margins cut the other way: subscription gross profit fell to 80% from 82% with no stated cause, and professional services gross loss widened to 5% from 2%. One real lever is that "certain AI and data solutions include a consumption-based pricing component."

moderate

The 10-K characterizes Marvell's markets as having 'pricing pressures' and intensifying competition (https://www.sec.gov/Archives/edgar/data/1835632/000183563226000011/mrvl-20260131.htm), yet the Q1 FY2027 release reports 52.1% GAAP / 58.9% non-GAAP gross margin on record revenue (https://www.sec.gov/Archives/edgar/data/1835632/000183563226000014/q127_8kx522026ex-991.htm) — differentiated-IP margins, tempered by hyperscaler buyer power.

weak

Vistra is a merchant price taker. Price formation rests on "the highest variable cost unit that clears the market", prices are "unpredictable and may fluctuate substantially", hedging markets have "limited liquidity after two to three years", and competing retailers "may offer different products, lower electricity prices and other incentives". ERCOT's $2,000/MWh figure is the low system-wide offer cap, applied conditionally when the peaker net margin exceeds three times CONE or under the PUCT Emergency Pricing Program, not a standing cap. PJM has "announced that it would propose" extending its capacity cap to 2028-29 and 2029-30, subject to FERC approval.

Summary

ServiceNow sells a workflow platform that sits on top of, rather than replaces, an enterprise's existing systems. Each customer gets a dedicated application layer and database, ITOM maintains a single record of all IT configurable items, and products integrate with existing workflows rather than replace them; once that record and its integrations span IT, HR and customer service, displacement becomes a re-platforming exercise. The evidence is in large commitments: $5 million-plus ACV customers rose from 420 to 502 to 603, and RPO reached $28.2 billion, up 27%, against $13,278 million of FY2025 revenue. The moat is bounded by a market the company itself calls fragmented with low barriers to entry, by larger rivals that can bundle or cut price, and by falling subscription gross margin, 82% to 80%.

Marvell is a fabless data-infrastructure silicon supplier whose center of gravity has shifted decisively to the AI data center: the data center end market was $6,100.3M, 74% of FY2026 revenue, up from 40% two fiscal years earlier (FY2026 10-K). Its strongest position is electro-optics — in high-end PAM4 optical DSPs for 400G+ transceivers it holds roughly 60% share on Inphi-inherited SerDes/FEC IP, with Broadcom above 30%, the two together over 90% (36kr, 2026-06-27). In custom AI silicon it is the structural #2 design partner at an estimated 20-25% of the custom AI ASIC design-services market versus Broadcom's ~70%, anchored by AWS Trainium and Microsoft Maia wins (hashrateindex, 2026-05-13). The Q1 FY2027 release (2026-05-27) shows the flywheel turning — record $2.418B revenue (+28% YoY), Q2 guided to $2.7B mid-point (+35% YoY), management citing 'exceptional AI-related bookings' across 800G/1.6T optics, 51.2T switches, CPO/NPO and custom XPU — and the Celestial AI (Photonic Fabric) and XConn (PCIe/CXL switching) acquisitions closed in February 2026 extend the interconnect moat toward scale-up fabrics. The offsets that keep the moat narrow are in Marvell's own filing: intense competition (AMD, Alchip, Astera, Ayar, Broadcom, Credo, GUC, Lightmatter and others), hyperscaler in-housing risk, and heavy customer concentration.

Vistra's moat is one scarce asset wrapped in a commodity business. Six NRC-licensed nuclear units - 6,448 MW, licences running 2036-2053 - sit inside a 43,641 MW fleet that the 10-K says operates in the majority as "merchant" facilities with no long-term power sales agreements and no guaranteed rate of return. That block cannot be rebuilt by a rival, and is now partly de-risked by 20-year PPAs with AWS (1,200 MW from Comanche Peak) and Meta (2,609 MW from the PJM plants) plus section 45U credits. Everything else - 26,989 MW of gas, 8,743 MW of coal, the 5m-customer retail book - competes on price in markets Vistra does not set, against entrants the filing says keep building "despite relatively low power prices". The 2025 growth was gas M&A (Lotus, pending Cogentrix), which widens the commodity-exposed side. Narrow, for a specific reason: the moat is 15% of the fleet.

Chain position

Enterprise workflow platform layered on top of customers' existing systems of record. It consumes public cloud capacity (named relationships with AWS, Google, Microsoft and NVIDIA) plus its own data centers, and reaches customers through a direct sales force, global system integrators (Accenture, Deloitte, EY, Infosys, KPMG) and resale partners. Microsoft is named as both partner and competitor.

Fabless supplier spanning 'data center core to network edge': it sits between hyperscaler AI compute (custom XPU/XPU-attach ASICs) and the optical layer (PAM4/coherent DSPs, CPO/LPO, DCI, AEC, PCIe retimers), outsourcing fabrication to independent CMOS foundries; the Feb-2026 Celestial AI and XConn acquisitions push it further into scale-up photonic fabric and PCIe/CXL/UALink switching (FY2026 10-K, https://www.sec.gov/Archives/edgar/data/1835632/000183563226000011/mrvl-20260131.htm).

Merchant IPP: sells energy, capacity and ancillary services into ISO/RTO spot and short-term wholesale markets (ERCOT, PJM, ISO-NE, NYISO, CAISO, MISO) and resells to ~5m retail customers. Emerging role as long-term nuclear offtake supplier to hyperscalers (AWS, Meta). Not a price setter at any link.
