Is SK Hynix profitable in 2026?

Yes. FY2025 revenue hit a record ~97.1 trillion won (~$64.1B) with net income of ~42.9 trillion won (~$28.3B), implying a roughly 44% net margin, driven largely by HBM demand for AI chips, per July 2026 reporting.

SK Hynix is publicly listed on the Korea Exchange (000660) and now Nasdaq (SKHY since July 2026). Its largest shareholder is SK Square Co., an SK Group affiliate, holding about 20.6%, followed by Korea's National Pension Service at roughly 8.1% as of mid-2026.

Could AI replace SK Hynix?

No. AI is SK Hynix's demand driver, not a threat to it, since AI cannot fabricate memory chips. SK Hynix held about 58% of global HBM revenue share in Q1 2026 and supplies roughly 70% of Nvidia's HBM4 orders as of July 2026.

Who is SK Hynix's biggest competitor?

Samsung Electronics is the closest rival, holding about 38% DRAM share versus SK Hynix's 29% in Q1 2026, and both were certified alongside Micron on June 5, 2026 to supply HBM4 for Nvidia's Vera Rubin platform, intensifying direct competition.

Will SK Hynix miss Q2 2026 earnings?

Korea Investment & Securities forecast on July 13, 2026 that SK Hynix would miss Q2 profit consensus by about 8% on slower HBM4 shipments, which triggered a 15% single-day stock collapse in Seoul that day, its worst day on record. Results were due July 22, 2026.

Is SK Hynix stock overvalued?

Possibly. Korea-listed shares rose over 630% in the trailing 12 months through mid-July 2026, pushing market value past $1 trillion, the second Korean firm after Samsung to hit that mark, even as a July 13, 2026 profit-miss forecast triggered a record 15% single-day drop.

The call

SK Hynix supplies the memory chips Nvidia's AI GPUs can't ship without, but its stock now prices in years of flawless execution against a fast-closing Samsung.

SK Hynix is a South Korean company that makes high-bandwidth memory chips used primarily in AI data centers and high-end graphics processors. The company holds a commanding lead with about 58% of the global market for this type of chip, and Nvidia allocates roughly 70% of its orders to SK Hynix, which is hard for competitors to replicate because building the factories costs 15 to 20 billion dollars, the manufacturing process takes decades to master, and SK Hynix has signed contracts locking in the relationship through 2030. Samsung, which already dominates regular memory chips, remains the one realistic rival that could narrow the gap in the next year or two if it can solve the manufacturing yield problems that currently hold it back. The stock has climbed 630% to a valuation over 1 trillion dollars, so even though the underlying business is strong enough to survive 3 to 5 more years, the next earnings report in Q2 2026 could disappoint investors who have already priced in perfect execution, and any loss of market share to Samsung would force a major rethink.

Why

AI pressure: None apparent. AI is the reason SK Hynix exists right now: Nvidia's GPU demand for HBM feeds its revenue, it doesn't eat it. Could AI do the core job? Unlikely.

Bigger players: Samsung Electronics. Samsung passed Nvidia's Vera Rubin HBM4 certification alongside SK Hynix and Micron, and could close the yield gap that keeps it behind. Could a giant copy it? No, they are blocked.

What protects it. A multi-year HBM4 co-development deal with Nvidia through 2030, plus a yield lead built over years that's hard to copy fast.

What would change this call

Samsung announces meaningful Nvidia HBM4 allocation (over 30% share) in earnings or Nvidia supply disclosures. Would show Samsung closing the HBM yield gap and eroding SK Hynix's Nvidia lock-in.
SK Hynix Q2 2026 earnings (due July 22, 2026) versus consensus. A miss confirming Korea Investment & Securities' 8% profit-miss forecast would signal HBM4 shipment slowdown.
CXMT's global DRAM share moving materially above 8% over the next year. Would show Chinese commodity DRAM competition pressuring pricing even without HBM overlap.

Key numbers

58% global HBM revenue share (Q1 2026)
70% of Nvidia's HBM4 orders (July 2026)
Stock up 630% in trailing 12 months (July 2026)

Named risks

Q2 2026 earnings miss risk after KIS forecast 8% profit shortfall, triggering 15% stock crash on 2026-07-13. Severity: high
Valuation fragility after 630% 12-month stock run to over $1T market cap at cycle peak. Severity: high
Antitrust exposure from June 25, 2026 US DRAM price-fixing lawsuit against SK Hynix, Samsung, Micron. Severity: medium
US export control tightening; China fabs lost automatic VEU status effective Dec 31, 2025, requiring annual licenses. Severity: medium
Samsung and Micron both certified for Nvidia Vera Rubin HBM4, threatening SK Hynix's allocation share over time. Severity: medium
