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.

The FY2025 10-K shows a moat that still pays but no longer compounds: total gross margin of 64.9% and remaining performance obligations of $43,533 million (up 6%) against a Networking product category that fell from $34,570 million in fiscal 2023 to $29,229 million in fiscal 2024 to $28,304 million in fiscal 2025, and a product gross-margin bridge in which 'Product pricing' subtracted 1.6 percentage points. All of the reported category growth came from Splunk-carrying lines - Security +59% and Observability +26%. Real and durable, but bounded: narrow, not wide.

Qualcomm's advantage is real but concentrated in one segment. The FY2025 10-K (filed 2025-11-05) describes its portfolio as "the most widely and extensively licensed in the industry" and says the industry "generally recognizes that any company seeking to develop, manufacture and/or sell certain cellular products requires a license or other rights to use our patents". That licensing leg produced $5,582M of FY2025 revenue against $38,367M at QCT, where Apple, Samsung and Xiaomi are all named in the vertical-integration risk factor and Apple already "utilizes its own modem... in certain of its smartphones". The filing frames the QCT loss as expected rather than realised.

Moat type 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.

The durable piece is the contracted annuity attached to installed equipment: total remaining performance obligations of $43,533 million, of which $21,961 million is services and $21,810 million is long-term (recognised beyond twelve months), carried at a services gross margin of 68.5% that has risen for three consecutive years from 66.4% and 68.1%. Customers keep paying for support on gear they already run.

intangibles ip

The durable asset is intellectual property accumulated since Qualcomm's founding "in 1985". The patents have "broad coverage in many countries, including Brazil, China, India, Japan, South Korea, Taiwan, the United States and countries in Europe" and are licensed "to hundreds of companies on industry-accepted terms", with royalties set as "a percentage of the wholesale (i.e., licensee's) selling price... subject to per unit minimums and/or per unit caps". R&D of $9,042M equalled 20% of revenues. Manufacturing is fabless "other than for certain of our RFFE modules and RF filter products", for which Qualcomm owns fabs in Germany and Singapore.

Leadership 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

The 10-K names no competitor and discloses no market share anywhere in Management's Discussion and Analysis. The positional facts it does give are scale and direction: Networking product revenue of $28,304 million in fiscal 2025 - by far the largest of its four categories - but down $6.3 billion from fiscal 2023, with channel partner financing volume falling from $32.1 billion to $27.1 billion to $24.9 billion across fiscal 2023-2025.

co leader

Leadership is clear in licensing and contested in silicon. The 10-K names no rival licensing programme and asserts the portfolio is "the most widely and extensively licensed in the industry", while calling QCT's industries "intensely competitive" and naming eleven competitors (Broadcom, HiSilicon, MediaTek, Mobileye, Nvidia, NXP, Qorvo, Samsung, Skyworks, TI, UNISOC); "continue to be a leader in mobile" appears in a list of things future success depends on, so it reads as aspiration, not share. The band therefore rests on the licensing leg, roughly 13% of revenue. FY2025 10%-plus customers were 21%, 20% and 13%; in 9M FY2026 only two cleared 10%.

Pricing power 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.

moderate

The product gross-margin bridge attributes fiscal 2025's 0.2-point improvement to productivity (+2.0 points) and mix (+1.1 points) while 'Product pricing' subtracted 1.6 points; a legal dispute with a supplier cost a further 0.8 points. Total gross margin of 64.9% (product 63.7%, services 68.5%) is held by cost and mix, not by price.

moderate

QTL margins held at 72% in FY2025 and 73% in 9M FY2026, though Q3 FY2026 alone slipped to 69% from 71%, and the $111M revenue gain there is attributed to revenues per unit "primarily driven by favorable mix" rather than to price. At QCT, the fall to 26% from 30% is explained by "lower gross margin, primarily driven by higher product cost, partially offset by higher average selling prices" plus lower revenues, so the pressure is cost rather than price; FY2025 handsets rose $2,930M, of which $2.5B came from higher revenue per chipset. Against that, "declining average selling prices" is a standing risk-factor title, "particularly pronounced in emerging regions and China".

Summary

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.

The installed base still switches slowly - but the filing does not claim it is winning the AI datacenter on the strength of that base. The fiscal 2025 Networking decline is attributed to 'product shipments returning to normalized levels during the first half of fiscal 2025 from the elevated levels ... in the first half of fiscal 2024', to servers, and to 'a decline in campus switching' - normalisation, not disclosed share loss, so the whitebox/Arista thesis is not something this 10-K either confirms or denies. What the filing does disclose is the shape of the AI dollar Cisco is actually winning: Americas service provider and cloud growth 'driven by AI infrastructure revenue from webscale customers', funded by additional purchase commitments 'related to manufacturing Cisco Silicon One and other products to meet demand from webscale and other customers', which 'significantly increased our supply chain exposure, which has resulted in negative impacts to our product gross margin in recent periods and may result in further negative impacts in future periods'. Enterprise switching earns 63.7% product gross margin; webscale silicon costs margin to serve. The moat is intact where the annuity is and thin where the growth is.

Qualcomm has two legs pointing in opposite directions. QTL (FY2025 revenue $5,582M, EBT margin 72%) rests on a portfolio the 10-K calls "the most widely and extensively licensed in the industry", with royalties struck on the licensee's wholesale device price under per-unit minimums and caps; its durability is dated in the filing, since "our patent license agreements with key OEMs are generally long-term, with terms expiring at varying dates between fiscal 2027 and 2031", some with binding-arbitration renewal clauses, and Huawei's licence has already expired, removing its royalties from QTL revenue from Q2 FY2025. QCT ($38,367M, 87% of segment revenue) is the leg under pressure: its three 10%-plus customers all build their own silicon, Apple already ships its own modem, and QCT EBT margin fell to 26% in Q3 FY2026 from 30%.

Chain position

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.

Supplies networking into AI datacenters: the 10-K ties Americas service provider and cloud growth to 'AI infrastructure revenue from webscale customers' and to Cisco Silicon One manufacturing commitments.

Every figure and quotation is drawn from the FY2025 10-K and the Q3 FY2026 10-Q. Where the filings state no market share, the share band is left unknown rather than inferred, and barrier bands follow the filings' own language, which states a barrier to entry only for automotive.
