Micron sits in a three-firm DRAM oligopoly (with Samsung and SK hynix), holds "over 60,000 patents" and leading-edge process technology (industry-first 1-gamma EUV DRAM node in FY2025), yet its FY2025 10-K concedes competitors "may use aggressive pricing" and "may have a larger market share," and consolidated gross margin swung from negative 9% (FY2023) to 40% (FY2025) — a real but commodity-cyclical, non-durable advantage.

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.

The FY2025 10-K describes a purpose-built AI cloud with a real performance edge, but its own risk section discloses the defining constraint: 'approximately 67% of our revenue from our top customer, Microsoft, for the year ended December 31, 2025' — a specialized platform whose economics rest on one buyer that is also a hyperscaler competitor is narrow, not wide.

The 10-K roots Micron's edge in proprietary technology and IP: "over 60,000 patents" granted as of Aug 28, 2025, "significant investments to develop proprietary product and process technology," the industry's first 1-gamma (EUV) DRAM node, ninth-generation G9 NAND, and HBM4 samples to key AI customers.

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.

The 10-K grounds the advantage in purpose-built infrastructure — first-to-deploy NVIDIA GB200/GB300 NVL72 systems and a data-center fabric 'designed to harness the full potential of each GPU' — a performance-per-dollar edge at scale, not a customer lock.

A member of the three-supplier DRAM oligopoly and at the technology frontier (industry-first 1-gamma EUV node), but the smallest of the three by share — the 10-K acknowledges competitors "may have a larger market share" — and a later entrant scaling up in HBM behind SK hynix and Samsung.

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%.

The 10-K positions CoreWeave as a first-to-deploy specialist against hyperscalers who offer AI compute 'as part of a broader product portfolio' — a leader of the purpose-built neocloud niche, not of the AI-cloud market its own filing says it competes in.

Memory is a commodity with cyclical ASPs: the 10-K flags "volatility in average selling prices" and competitors' "aggressive pricing" as key risks, and consolidated gross margin swung from -9% (FY2023) to 22% (FY2024) to 40% (FY2025), marking Micron largely as a cyclical price-taker; contract-based, supply-tight HBM is a partial exception.

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".

A first-to-deploy performance edge on scarce new NVIDIA systems supports pricing while the hardware is scarce, but 67% single-customer concentration is buyer leverage the filing states outright.

US-based supplier of the memory tier of the AI stack — DRAM, HBM and NAND; the 10-K notes cloud servers for AI and data-centric workloads "require significantly increasing quantities of DRAM, including HBM," and Micron sampled HBM4 to power next-generation AI platforms.

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.
