| Vistra | Digital Realty Trust | GE Vernova | |
|---|---|---|---|
| Moat rating | 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. | narrow The FY2025 10-K's own competitive record cuts both ways. Item 1 says a "high-quality, highly interconnected global portfolio such as ours could not be easily replicated today on a cost-competitive basis," yet Item 1A concedes that competitors have "significantly greater financial, marketing and other resources and more ready access to capital" and that as rivals keep developing space, "rental rates may be reduced or we may face delays in leasing." A durable advantage that its own filing says new supply can price against is bounded, not unassailable. | wide FY2025 10-K (filed 2026-01-29): the installed base generates approximately 25% of the world's electricity; the Power segment carries ~$94.4B of remaining performance obligations with ~1,800 of ~7,000 installed gas turbines under long-term service agreements averaging ~10 years of remaining contract life; and the filing states demand is 'exceeding available capacity' for its products — a contracted, decade-scale service annuity on proprietary installed equipment. |
| Moat type | 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. | network effects Item 1 attributes the hard-to-replicate part of the portfolio to connectivity rather than to real estate: "the network density, interconnection infrastructure and connectivity-centric customers in certain of our data centers have led to the organic formation of densely connected data communities that are difficult for competitors to replicate." That community sits on over 232,000 cross connects in over 55 metros, so each network and cloud that lands makes the same building worth more to the next tenant. | switching costs 10-K: ~1,800 gas turbines under long-term service agreements with ~10-year average remaining life, plus services agreements on ~24,000 of ~59,000 installed onshore wind turbines — service revenue is contractually tied to GE Vernova's own installed fleet; the filing adds it derives 'a sustained competitive advantage both from our IP portfolio as well as technical know-how embedded in our products and manufacturing techniques developed over decades'. |
| Leadership | 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. | co leader Item 1 claims the title of "the largest global provider of cloud- and carrier-neutral data center, colocation and interconnection solutions," but the Competition section names Equinix and NTT as operators of properties "similar to ours in some of the same metropolitan areas," plus Global Switch and regional operators abroad — a shared top tier on the company's own telling, not a solitary one. | co leader 10-K opens with 'GE Vernova is a global leader in the electric power industry' and its installed base generates ~25% of world electricity, but the filing names peer-scale competitors in every segment — Siemens Energy in both Power and Electrification, Mitsubishi Power, Vestas, Hitachi Energy, Schneider Electric, ABB — so co-leader across the portfolio rather than clear leader. |
| Pricing 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. | strong FY2025 renewals signed re-priced upward in every bucket — +27.0% on greater-than-1 MW space ($146 to $186 per square foot), +4.6% on 0-1 MW ($268 to $280) and +43.0% on other ($49 to $71) — and MD&A expects average aggregate rental rates on 2026 renewals to be positive against the rates currently paid for the same space "on a GAAP basis and on a cash basis." On costs, the filing says utilities expense "is our largest expense category" and that "the vast majority of the expense is passed directly through to our customers," which it credits with significantly mitigating exposure to power-cost increases rather than removing it. The cap: Item 1A warns competitor development could still force rates down. | strong 10-K: 'increasing demand exceeding available capacity', Electrification customer lead-times 'increased as a result of demand outstripping supply', and both Power and Electrification state they adjust pricing 'in line with market demand, inflation, and industry dynamics'; trade press (Power Engineering, 2026-04-23) reported new gas-turbine order pricing in H1 2026 tracking 10-20 points higher on a dollar-per-kilowatt basis than Q4 2025 orders. |
| Summary | 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. | Digital Realty rents space, power and connectivity rather than compute: at 2025 year-end its portfolio held 310 data centers and roughly 57.6 million rentable square feet across more than 55 metros in over 30 countries, about 84.7% leased, serving more than 5,000 customers. Two different businesses sit inside that footprint. The greater-than-1 MW wholesale side is a capital-and-power race — 769 MW of projects underway with 64% pre-leased, and land that "could accommodate over 3,500 megawatts of additional data center capacity" — where the 10-K names Equinix, NTT, Global Switch and "various private operators" as rivals and warns that added supply can push rents down. The colocation and interconnection side is the defended half: over 232,000 cross connects and the "densely connected data communities" Item 1 says competitors cannot easily replicate, reinforced by contracts the filing describes as generally running 5-10+ years on large deployments and by improvements "installed at our customers' expense." FY2025 leasing supports that read — renewals signed re-priced +27.0% on greater-than-1 MW space and +4.6% on 0-1 MW — while customer concentration is the offsetting exposure, with the largest customer at roughly 11.7% of annualized recurring revenue. | GE Vernova's moat rests on its installed base: the FY2025 10-K states its equipment generates approximately 25% of the world's electricity, with ~7,000 installed gas turbines (~1,800 under long-term service agreements averaging ~10 years of remaining life) and ~$94.4B of Power-segment remaining performance obligations. The filing reports demand 'exceeding available capacity', lengthening Electrification lead-times 'as a result of demand outstripping supply', and pricing adjusted with demand — scarcity trade press later quantified as new gas-turbine order pricing tracking 10-20 points higher per kW in H1 2026 than Q4 2025, with only ~10 GW of production slots left across 2029-2030 (Power Engineering, 2026-04-23). The moat is not uniform: the 10-K risk section flags intensifying competition as manufacturers from China 'improve quality and reliability and pursue markets outside their home countries', and Offshore Wind is delivering its backlog under project-cost and execution pressure, compounded by the U.S. Interior Department's December 22, 2025 pause of leases for all large-scale U.S. offshore projects under construction, which directly impacted the Vineyard Wind timeline. Nuclear adds optionality: the 10-K cites an SMR deployment agreement it calls 'the first commercial contract of its kind in North America' via its joint ventures with Hitachi. |
| Chain position | 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. | Landlord to the AI stack — sells the space, power and interconnection that cloud, network and enterprise tenants run compute in (Oracle, IBM, Meta Platforms, AT&T, Comcast and Lumen are among the customers named in Item 1), with roughly 2.9 GW of total in-place IT capacity. | Power supplier to the AI buildout: the 10-K states gas power serves 'rising electricity demand from hyperscalers and data centers' and Electrification benefits from orders to electrify data centers 'playing a key role in the development of artificial intelligence (AI)'; trade press (Power Engineering, 2026-04-23) put roughly 20% of the ~100 GW of gas capacity under contract as explicitly tied to data-center load. |
