SK hynix supplies memory used in servers, AI accelerators, PCs and mobile devices. Equipment manufacturers pay it for products tailored to their designs. DRAM, including high-bandwidth memory (HBM), brings in most of its revenue; NAND flash and storage products such as enterprise solid-state drives provide most of the rest. It operates the acquired Intel NAND and storage business through Solidigm.
HBM moves data quickly for GPUs and AI computing. Supplying it requires SK hynix to coordinate development with customers and pass rigorous testing and approval. Demand for HBM and server DRAM depends heavily on AI infrastructure spending. A limited group of customers in the United States and China accounts for a substantial share of sales, so their purchasing decisions carry considerable weight.
The business requires continuing investment in factories, equipment and manufacturing technology. Earnings depend on producing usable chips efficiently and reducing costs as memory prices change. Industry capacity can grow faster than demand, creating oversupply and falling prices.
Its China factories need annual U.S. approval to receive covered U.S.-origin equipment; the company holds a license for 2026. Chinese conditions on the Intel NAND acquisition also require reasonable pricing and production levels and support for competitors entering China's enterprise SSD market.
The risk section is the longest, dullest part of the filing. This keeps only what can really hurt you: where it hits, how hard, when it plays out.
Every company claims an edge. Each one is checked against hard numbers like margins and returns: which hold, and which line gives way first.
SK hynix’s results hinge on memory prices and AI infrastructure demand, with Samsung Electronics—the absent rival in DRAM, HBM and NAND—also worth watching.
Micron competes with SK hynix to sell HBM, DRAM and NAND to cloud, computing and device manufacturers, exposing both to memory demand and pricing pressure. Watch Micron’s HBM and server-memory sales to cloud customers for a read on the AI demand SK hynix also serves.
NVIDIA buys SK hynix memory for its GPU platforms, so sales and product transitions in its AI accelerators matter to SK hynix’s HBM demand. Watch NVIDIA’s data-center computing platforms rather than its gaming graphics business for this tie.
Sandisk competes with SK hynix in NAND flash and enterprise and client SSDs, tying both to flash-storage demand and selling prices. Its SSD sales to cloud providers, enterprises and PC customers offer a view of SK hynix’s storage markets, not its HBM business.
SK hynix relies on Lam Research’s chipmaking equipment to expand memory capacity and improve manufacturing processes. Lam’s equipment business with memory makers is a window into factory investment, which can lower SK hynix’s unit costs but also raises depreciation and financing costs.
TSMC makes and packages AI processors for chip designers that integrate SK hynix’s HBM, linking both companies’ growth to accelerator production and available packaging capacity.
FormFactor supplies SK hynix with products that probe and test chips, and depends materially on that customer’s purchases. SK hynix contributed 19.2%–25.0% of FormFactor’s revenue in individual quarters of 2025, making that customer revenue a concrete measure to watch.
SK hynix buys Rambus chips that connect memory within server modules, linking Rambus’s product sales to server-memory demand. Watch its memory-interface chip revenue for a view of this market, while remembering it also sells to other memory makers, system manufacturers and cloud providers.
Broadcom and SK hynix share exposure to expanding AI infrastructure: Broadcom supplies custom AI accelerator and networking chips, while SK hynix supplies the memory that infrastructure needs.
Marvell and SK hynix depend on data-center spending in different ways: Marvell sells custom computing, interconnect and storage chips, while SK hynix supplies memory and storage for increasingly memory-intensive systems. Watch Marvell’s data-center revenue, which accounted for 74% of sales in the year ended January 31, 2026.
Silicon Motion supplies SK hynix with chips and firmware that manage NAND storage, linking it to SSD and embedded-storage shipments. SK hynix contributed more than 10% of its revenue in 2023, but was not listed among its over-10% customers in 2024 or 2025, so that historical dependence should not be treated as current.
Super Micro’s AI and cloud server deployments increase demand for the HBM, server DRAM and enterprise SSDs SK hynix sells. Watch its server and rack-scale systems business with enterprise data centers and cloud providers for a view of demand across those three memory and storage layers.
Lam Research Corp earningsLRCX
Lam Research’s report shows how memory makers are spending on chipmaking equipment, which can shape SK hynix’s capacity growth, process improvements and depreciation costs.
Look at Lam’s memory-related equipment demand or sales, if disclosed, alongside its overall equipment business. Stronger investment by memory makers points to capacity additions or process upgrades: SK hynix could gain room to expand and lower unit costs, but added capacity can also increase supply and depreciation. Weaker investment suggests a slower build-out, with less new supply but fewer opportunities to improve costs. The takeaway is whether equipment investment looks more like a cost and productivity benefit for SK hynix or a future capacity burden.
SK hynix Inc. earningsThis company
DRAM drives most of SK hynix’s sales, and this report will show whether demand for AI and server memory is translating into profit as prices and manufacturing costs change.
Read DRAM sales alongside gross margin, and use any HBM or server-DRAM detail the company provides to see which products are driving sales. Rising sales with a steady margin would show that prices, shipments and manufacturing costs are working together; rising sales with a falling margin would mean lower prices, higher costs or yield problems are eating into the gains. The conclusion is whether SK hynix is turning memory demand into profit, or simply selling more product.
Nvidia Corp earningsNVDA
NVIDIA’s data-center platforms use memory supplied by SK hynix, so its report will show whether demand for AI accelerators is still supporting this HBM market.
Focus on NVIDIA’s data-center platform sales and any detail on HBM needs or product transitions. Strong platform sales with continued HBM demand would support the AI memory market SK hynix serves; weaker platform demand, or a transition that reduces need for the relevant memory, would put that sales channel under pressure. NVIDIA’s results are not SK hynix’s sales figures, but they help show whether demand from this HBM customer is holding up or cooling.
Micron Technology, Inc. earningsMU
Micron competes with SK hynix for HBM, DRAM and NAND customers, so its sales and pricing will show the demand and competitive pressure they share.
Read Micron’s HBM and server-memory sales alongside any pricing or product-mix detail it reports. Firm sales and pricing would suggest demand is supporting these markets, a helpful industry signal for SK hynix; weaker sales or softer pricing would point to pressure on demand or the supply-demand balance. Strong Micron sales could also mean it is winning business from the same customers. The conclusion is whether SK hynix is facing a supportive memory market or stronger competitive and pricing pressure.
