The FY2025 10-K describes the nation's largest nuclear fleet — approximately 22 GW across 14 stations producing 68% of 2025 electric supply — running at a 94.7% capacity factor that 'has been approximately four percentage points better than the industry average annually since 2013', with NRC licences extending to 2054 and an IRA nuclear production tax credit floor from 2024.

The FY2026 10-K (filed 2026-07-29) shows contracted revenue, not a demonstrated competitive edge. About 1,410 MW is leased under 15-year take-or-pay, non-cancellable base terms worth about $36.2 billion, but only about 100 MW of the roughly 1.5 GW that is contracted and either operating or under construction was operating and earning revenue at May 31, 2026, and Item 1A says "lessees may have the right to terminate applicable leases if there are significant delays in construction." Item 1A also concedes "We do not have the resources to compete with larger providers of similar products or services at this time," and the Competition section names 13 power-advantaged developers the company competes with. Signed leases give revenue visibility, but the filing does not show a durable advantage.

The FY2026 10-K (fiscal year ended March 31, 2026) concedes the core business is contested on every side: "Our industry is extremely competitive, many of our competitors have achieved substantial market share, and some may have lower cost structures or greater design, manufacturing, financial or other resources than we do." Customers "could in the future decide to in-source, dual-source, regionalize, or otherwise reallocate manufacturing volumes among suppliers", certain contracts "permit the customer to terminate the agreement for convenience upon prior written notice", and hyperscale customers "typically have substantial purchasing power and negotiating leverage". TradingPilot's stored fundamentals (SEC XBRL) show gross profit of $1,976 million on net sales of $28,502 million in fiscal 2023 and $2,567 million on $27,914 million in fiscal 2026: a thin margin, even after widening. The Cloud and Power Infrastructure (CPI) segment sells its own power and cooling products, but the 10-K says it must keep offering "significant price and/or performance advantages over competitive products", and Flex intends to separate it into an independent company targeted for the first quarter of calendar 2027. A large contract manufacturer whose own filing describes no protected position: no moat is claimable.

Moat type cost scale

The cited edge is operating cost at scale: average refuelling outages of 22 days in 2025 against industry averages of 33 and 38 days in 2024 and 2023, a capacity factor about four points above the industry every year since 2013, and 'significant economies of scale' in what the filing calls the largest US customer-facing energy platform.

The 10-K claims three advantages: power-advantaged sites (it believes securing power and interconnection ahead of demand is 'the principal constraint on new HPC capacity and a core differentiator for us from many of our competitors'), a standardized 'franchise-style' design, and hyperscaler master service and master telecom service agreements 'that are difficult to obtain.' The filing does not show any of them to be durable. Its Competition section says competition 'centers on securing and developing sites with access to large-scale, reliable, and cost-competitive power and interconnection' and names 13 power-advantaged developers going after the same leases, and Item 1A concedes it lacks the resources to compete with larger providers. Signed leases are take-or-pay and non-cancellable, so a tenant leaving for convenience owes 'the full remaining contractual value,' but that is contractual lock-in on each lease rather than a moat source, so no moat type is assigned.

The 10-K's competitive strengths are operating capabilities, not a durable barrier: "Global Scale and Regional Strength" (more than 100 facilities across approximately 30 countries, staffed by approximately 150,000 employees), "Long-Standing, Diverse Customer Relationships", "Cross-Industry Synergies" and cost-efficient industrial parks. On intellectual property it says "we do not consider any single patent, trademark, or license to be material to our business as a whole" and that the carrying value of its intellectual property "was not material". Switching costs are limited by short commitments: "We generally do not obtain firm, long-term purchase commitments from our customers", and termination-for-convenience notice periods "may be relatively short".

Leadership clear leader

The 10-K states Constellation is 'the largest nuclear energy company in the U.S.', is 'the nation's largest energy supplier for C&I and residential power volumes' based on EEI data, and has 'over 32% of the C&I market share of direct customer business'.

behind

The 10-K makes no leadership claim and gives no ranking or share figure. Item 1A concedes "We do not have the resources to compete with larger providers of similar products or services at this time" and that some rivals have "substantially greater liquidity and financial resources than we do." Its Competition section places APLD against established operators (Digital Realty, Equinix), hyperscalers that build their own capacity, independent developers and 13 named power-advantaged developers (IREN, Cipher Digital, TeraWulf, Hut 8, Riot, CleanSpark, HIVE, Core Scientific, Bitdeer, Galaxy Digital, Fermi, Keel Infrastructure, MARA).

at parity

EMSNOW/in4ma's "EMS&ODM Global 100" (2026-03-06, https://www.emsnow.com/?p=53535) says Wistron, Quanta and Wiwynn "plus Foxconn together account for nearly 57% of global EMS/ODM production", and groups Flex with Jabil, Celestica and Sanmina as the US "big four", "representing about 85% of the revenue base among ~20 US headquartered EMS/ODM". The FY2026 10-K claims no rank and says "many of our competitors have achieved substantial market share". One of a handful of large Western contract manufacturers, behind the Taiwanese leaders in scale: at parity with its peer group, not a leader.

Pricing power moderate

The 10-K states 'While providing customers with a competitive price is a key focus' in retail, on roughly two-year average C&I contract terms with 77% power and 84% gas renewal rates in 2025, and the nuclear fleet's downside is set by the IRA nuclear PTC 'as unit revenues decline below levels established in the IRA'; SEC-reported operating income was 13.6% of revenue in 2025.

weak

Item 1A says "Due to the limited number of hyperscalers, we expect that a limited number of customers will continue to account for a high percentage of our revenue for the foreseeable future," and that if customers' equipment usage declines or they discontinue use of its facilities, APLD "may be compelled to lower our lease prices in some instances or risk losing a significant customer." One customer was 59% of FY2026 revenue from continuing operations. Take-or-pay, non-cancellable terms protect contracted revenue over the base term, and Note 19 reports a $39.1M HPC Hosting segment profit on $385.3M of segment revenue in FY2026, but those terms are agreed with a small group of concentrated buyers.

weak

Stored fundamentals show gross profit of $1,976 million on $28,502 million of net sales in fiscal 2023 and $2,567 million on $27,914 million in fiscal 2026; on the Q1 FY2027 call (https://earningswhispers.com/transcript/FLEX/Q12027) the CFO said adjusted gross margin "improved to 9.6%, up 50 basis points from the prior year". The 10-K sets the limits: hyperscale customers have "substantial purchasing power and negotiating leverage, which they may use to obtain favorable pricing, extended payment terms, volume flexibility, or other concessions that could reduce our margins", and if CPI's competitors "adopt innovations more quickly or develop superior products, our win rates, pricing, and margins may suffer".

Summary

Constellation pairs the largest US nuclear fleet with the largest competitive retail book, which lets it sell around-the-clock carbon-free power under long-term contracts such as the 20-year Microsoft PPA restarting Three Mile Island Unit 1 as the 835 MW Crane Clean Energy Center.

Applied Digital designs, builds and operates purpose-built, liquid-cooled HPC data centers, which it calls 'AI factories', and leases the capacity to CoreWeave and investment-grade hyperscalers. At May 31, 2026 its 10-K lists five campuses (Polaris Forge 1-3 and Delta Forge 1-2) with about 1,410 MW contracted under roughly 15-year take-or-pay, non-cancellable leases worth about $36.2 billion over the base terms. The filing claims three sources of advantage: it controls power-advantaged sites, it uses a standardized 'franchise-style' design built to deliver about 150 MW in about 14 to 18 months, and it holds hyperscaler master agreements that are 'difficult to obtain.' The same document shows how early the company is. About 100 MW was operating and earning revenue. One customer was 59% of FY2026 revenue from continuing operations. It competes with Digital Realty, Equinix, hyperscalers that build their own capacity and 13 named power-advantaged developers, and it concedes that it lacks the resources to compete with larger providers. Signed leases give long-dated revenue visibility, but the filing does not show a durable competitive advantage.

Flex designs, builds and manages products for other companies through, per its FY2026 10-K, three segments: Integrated Technology Solutions (communications, enterprise and lifestyle products), Regulated Manufacturing Solutions (industrial, automotive and healthcare) and Cloud and Power Infrastructure (integrated compute systems, liquid cooling, and utility-, facility-, rack- and board-level power). It runs more than 100 facilities in approximately 30 countries; its ten largest customers were 45% of fiscal 2026 net sales and none exceeded 10%. The data-centre business is the growth engine: on the Q1 FY2027 call (2026-07-29) the CFO said CPI revenue "totaled $2.2 billion, up 35% from the prior year, driven by strong growth in power", at a 9.7% adjusted operating margin, against 5.2% for ITS and 6.6% for RMS. Flex plans to spin CPI off as Axiom in the first quarter of calendar 2027, after funds affiliated with General Catalyst, Koch Equity Development and co-investors agreed a $2.0 billion convertible preferred investment "at an initial enterprise value for Axiom of $37.5 billion" (Flex release, 2026-10-05: https://www.sec.gov/Archives/edgar/data/866374/000119312526413173/d123485dex991.htm). The filing itself describes no durable barrier: the industry is "extremely competitive", rivals including Taiwanese ODM suppliers "in some cases, have a substantial share of global information technology hardware and related infrastructure production", customers can in-source or reallocate volume, and hyperscalers can use their leverage "to obtain favorable pricing". An independent tally (EMSNOW/in4ma, 2026-03-06) puts Foxconn, Wistron, Quanta and Wiwynn at "nearly 57% of global EMS/ODM production" and counts Flex among the US "big four". Scale plus a fast-growing power franchise that is about to leave the group, but no moat.

Chain position

Generator and retailer in one — the fleet is the physical supply behind the long-term carbon-free contracts it sells to large corporate buyers.

Developer and landlord of power-advantaged, liquid-cooled AI data-center capacity, leased long-term to CoreWeave and investment-grade hyperscalers.

Contract designer-manufacturer across many end markets and, through CPI, a supplier of power, cooling and rack-level compute infrastructure to "a limited number of hyperscale cloud providers, colocation companies, and large enterprise data center operators" (10-K), which Flex plans to separate as Axiom in the first quarter of calendar 2027.
