Up to three covered companies, band by band. Every call is a curated editorial judgment, never a disclosed figure — and every band carries its cited basis.
| SK Hynix | MediaTek | |
|---|---|---|
| Moat rating | narrow SK hynix held ~62% of the AI-critical HBM market in Q2 2025 (Counterpoint, via TweakTown) and was first to mass-produce HBM4, but memory remains a cyclical three-player business where Samsung and Micron are closing the HBM gap — a real but contestable edge. | narrow Counterpoint's public quarterly AP-SoC table, published 8 September 2026, shows MediaTek first in all ten quarters it covers (Q1 2024 through Q2 2026), never below 31%, with the nearest rival never above 30% -- a sustained position, not one good quarter. What the same table does not show is a widening one: the share oscillates inside a 31% to 41% band, the Q1 readings step down 41% (2024), 38% (2025), 33% (2026), and the 31% of Q2 2026 matches the lows already set in Q4 2024 and Q4 2025 rather than breaking them; Q2-on-Q2 the series runs 34%, 36%, 31%. Counterpoint also records MediaTek's shipments down more than 30% year-over-year in the quarter, the mainstream and entry tiers hit by the memory shortage and the premium tier by a 'slowdown in sales of Dimensity 9000 series powered devices.' MediaTek's own 2Q26 remarks show the gross line holding and the operating line not: gross margin 46.2%, down only 0.1 percentage points sequentially and guided at 46% plus or minus 1.5 for Q3, while operating income fell 22.2% year-over-year on revenue up 1.2% as operating expenses rose to NT$47.4 billion from NT$44.5 billion. A first place held for ten quarters without extending it, and earning less on it, is defensible rather than compounding. |
| Moat type | intangibles ip The advantage is process-and-packaging technology leadership: SK hynix achieved industry-first HBM4 mass production in September 2025 and has positioned itself as NVIDIA's key HBM partner, per its record FY2025 results. | intangibles ip MediaTek manufactures nothing itself -- its 2Q26 remarks describe 'deep design-technology co-optimization (DTCO) with TSMC' and close collaboration with advanced-packaging partners -- so the durable asset cannot be plant scale, and the remarks do not claim customer lock-in either. They locate it in a reusable design library: 'Building on our industry-leading IP portfolio, we offer best-in-class, pre-validated subsystems solutions for memory, I/O, and connectivity' -- which, the company says, 'largely reduces design complexity and shortens time to market for our data center customers'. The same remarks itemise 448G SerDes with a Co-Package Copper system solution, CPO development on TSMC's COUPE platform, and an end-to-end 3.5D platform with 'best-in-class 3.5D IP, packaging, and design flows,' and say design wins come 'backed by our industry-leading IPs, deep ecosystem partnerships, and proven execution capabilities'. The spending behind that library shows in the cost line: operating expenses of NT$47.4 billion in the quarter against NT$44.5 billion a year earlier, with the Q3 operating expense ratio guided at 31% plus or minus 2 points. It is the same library MediaTek re-amortises across mobile, edge and now data-center ASIC. |
| Leadership | clear leader Clear leader in HBM (#1 at ~62% share, Q2 2025) and became the world's top overall memory supplier in Q2 2025; caveat: it sits #2 to Samsung in commodity DRAM by volume and Micron/Samsung are narrowing the HBM gap heading into HBM4. | co leader Counterpoint has MediaTek ahead of every rival in all ten quarters of its public table -- 31% against Qualcomm's 23% and Apple's 19% in Q2 2026 -- but that count covers smartphone application processors only, and MediaTek's 2Q26 remarks put mobile phone at 41% of group revenue, no longer its largest business. Smart Edge Platforms is larger at 53%, and while the remarks claim 'continued market share gains across connectivity, computing and automotive products', no independent count of those positions appears in the sources used here. In data center MediaTek holds nothing yet: production of its first AI accelerator ASIC is scheduled for the fourth quarter of 2026, and 15% to 20% is a 2027 target raised from 10% to 15% a quarter earlier. Inside its core market the flagship tier is a stated plan rather than a claimed position -- a 2nm SoC launching in the third quarter and, 'together with ongoing engagements with global players, we will increase our presence continuously in the flagship smartphone market in 2027' -- while Counterpoint records MediaTek's premium-tier shipments declining on a 'slowdown in sales of Dimensity 9000 series powered devices.' |
| Pricing power | strong FY2025 operating margin hit a record 49% (operating profit +101% YoY) as HBM revenue more than doubled — unusually strong pricing power for a memory maker, per SK hynix's FY25 release. | moderate The 2Q26 remarks describe price as cost pass-through rather than capture: 'As rising costs across the supply chain have become an industry-wide reality, we are taking pricing actions to ensure these increases are appropriately reflected in our product pricing', with the full-year aim, 'through our disciplined pricing strategy', to 'deliver our full year gross margin within the current quarter guidance range' -- holding a band, not widening it. The realised figures show that defence working: gross margin 46.2%, down 0.1 percentage points sequentially, with Q3 guided at 46% plus or minus 1.5 points. The 2.9-point year-over-year decline is not an erosion rate; the company states it 'was mainly due to a one-time benefit in the year-ago quarter.' Holding a mid-40s gross margin through a market the company expects to decline 'by about 15% in units this year' is genuine discipline, but passing rising costs through to defend a guided band is not the ability to price above it. |
| Summary | SK hynix's durable advantage rests on an HBM process-and-packaging lead: it held roughly 62% of the HBM market in Q2 2025 (Counterpoint) as NVIDIA's key HBM partner, and delivered industry-first HBM4 mass production. That lead drove record FY2025 results with a 49% operating margin, though rivals are qualifying competing HBM parts. | MediaTek is the largest supplier of smartphone application processors by units and has been for as long as Counterpoint's public quarterly table runs. Across all ten quarters it covers, Q1 2024 through Q2 2026, MediaTek is first every time and never below 31%, while the nearest rival never clears 30%; in Q2 2026 it holds 31% against Qualcomm's 23%, Apple's 19%, UNISOC's 13%, Samsung's 9% and HiSilicon's 5%. That is a real, independently counted position, and it is the only part of MediaTek's business for which such a count exists in the sources used here. The same table is the clearest evidence that the position is being defended rather than extended. MediaTek's share moves inside a 31% to 41% band across the ten quarters, and the top of that band has come down -- 41% in Q1 2024, 38% in Q1 2025, 33% in Q1 2026 -- while the 31% of Q2 2026 matches the lows already set in Q4 2024 and Q4 2025 rather than breaking them; measured like for like against the same quarter a year earlier the series runs 34%, 36%, 31%. Counterpoint records MediaTek's shipments falling more than 30% year-over-year in the quarter -- hit in the mainstream and entry tiers by the memory shortage, and in the premium tier by a slowdown in Dimensity 9000 series devices -- while Samsung's Exynos climbed to 9% on Galaxy S26 base variants and mid-tier A-series wins. MediaTek's own 2Q26 remarks show the gross line holding and the operating line not: gross margin of 46.2%, down 0.1 percentage points sequentially and guided at 46% plus or minus 1.5 for the third quarter, against operating income down 22.2% year-over-year on revenue up 1.2%, with operating expenses of NT$47.4 billion against NT$44.5 billion a year earlier. Unit leadership held while the return on it did not. What MediaTek re-uses is design IP. It manufactures nothing itself -- the remarks describe deep design-technology co-optimization with TSMC and close work with advanced-packaging partners -- and they locate the durable asset in a pre-validated library of memory, I/O and connectivity subsystems, 448G SerDes with a Co-Package Copper system solution, CPO development on TSMC's COUPE platform, and an end-to-end 3.5D platform. The spending behind that library is visible in the cost line: operating expenses of NT$47.4 billion in the quarter against NT$44.5 billion a year earlier, with the Q3 operating expense ratio guided at 31% plus or minus 2 points against a gross margin guided at 46% plus or minus 1.5 -- an operating cost base running near a third of revenue. That library is now pointed at two adjacencies. Smart Edge Platforms -- connectivity, computing, automotive and TV SoCs -- is now the larger business, at 53% of revenue in Q2 against mobile's 41%, and grew 26% year-over-year while mobile fell 20%. And the company says it has built its first AI accelerator ASIC for a major US cloud customer, with production scheduled for the fourth quarter of 2026. One adjacency is a target and one is a contribution, and this profile treats them as exactly that. The data center share figure of 15% to 20% is a 2027 target against a served market MediaTek itself sizes at US$80 billion, raised from 10% to 15% only one quarter earlier, and production of the first ASIC was still scheduled for the fourth quarter at the date of the remarks. The RTX Spark AI PC work is corroborated by NVIDIA's own announcement, which credits MediaTek with collaborating on the custom CPU design and contributing to its power efficiency, performance and connectivity -- but the superchip, its Grace CPU, its NVLink-C2C interconnect and its software stack are NVIDIA's, and the systems ship from PC makers, so what MediaTek holds is a design contribution rather than a franchise with a share to count. The claimed share gains in connectivity, computing and automotive carry no number and no third-party count. The honest reading is a company with one durable, independently verified franchise it is holding rather than extending, funding a credible but still unproven move into higher-value silicon on the strength of its IP portfolio. |
| Chain position | Primary supplier of HBM (high-bandwidth memory) stacked onto NVIDIA's AI accelerators; HBM represented roughly 77% of Q2 2025 revenue. | A fabless designer sitting between its customers and the TSMC-centred manufacturing chain. The 2Q26 remarks describe 'deep design-technology co-optimization (DTCO) with TSMC' and close work with advanced-packaging partners to build 'high-performance ASICs across a broad range of very-large chip sizes using CoWoS and EMIB-T technologies' at nodes down to 2nm, and say MediaTek creates 'significant value beyond semiconductor by orchestrating other key components throughout the supply chain such as memory and substrate' -- a coordinator role as much as a design one. |
