A practicing semiconductor engineer's daily read on global silicon news:
NVIDIA reports fiscal Q1 today with consensus at $78B revenue / $73B DC and options pricing ±8-10% moves, while Mizuho lifted Micron ($800), TXN ($300), and STM ($68) targets simultaneously and Nomura sees another 110% upside in Korean memory names.
Chase's Take — From an STA/backend engineer's seat, today's most important signal isn't NVIDIA's revenue print — it's Hanmi Semiconductor's 30% collapse. TC bonder revenue dropping 65.5% QoQ means HBM3E line capex has run its course and HBM4 16-Hi bonders aren't booked yet, reconfirming that memory ramp isn't a smooth multiplicative curve but a staircase with generational discontinuities. Mizuho taking Micron's PT to $800 while explicitly stating 'supply tight through 1H 2027' means HBM4 cube quality yield and TSV stack yield — i.e., back-end — are dragging the ASP curve, which lines up with Lam Research guiding advanced packaging revenue +50%. If the union strike actually kicks off on the 21st, JPMorgan's 2.1-3.5 trillion won OP hit lands directly on the quarterly P&L, but the real problem is the second-order effect: Pyeongtaek P3 HBM4 line qual slips, and the H2 2026 ramp tilts further toward SK hynix/Micron. Next quarter's watch-points: (1) whether H200 China revenue gets visibility on tonight's NVIDIA call, (2) whether the May 21 strike actually takes effect, (3) whether TSMC's May revenue on June 10 prints another -1.1% MoM after April. The memory cycle isn't peaking now — the peak is when HBM4E qual finishes in 1H 2027, and the PT-raise race trying to front-run it just started with Mizuho's triple. That's why former president Kyung Kye-ho's 'H2 2027 price decline' warning carries weight.
1. NVIDIA Q1 FY27 earnings preview — consensus $78B / DC $73B / non-GAAP EPS $1.77, Blackwell→Rubin handoff is the key
TL;DR — NVIDIA reports Q1 FY27 after the May 20 close. Consensus revenue ~$78B (whisper $79-80B), non-GAAP EPS $1.77, data center revenue ~$73B. Options are pricing an 8-10% move, and with Blackwell at close to 70% of data center compute last quarter, smoothness of the Rubin handoff and China commentary are the call's biggest variables.
2. Samsung labor-management talks reach brink — bonus formula standoff, 18-day strike D-1
TL;DR — Samsung's union and management held last-mile talks May 19 over the bonus formula. Union demands a 15% semiconductor OP bonus pool split 70/30 (division-flat / business-unit performance); management counters 60/40 with a +9-10% bump if OP clears 200 trillion won. An 18-day strike by union members starts May 21 absent a deal.
3. SK hynix accelerates Yongin fab buildout — memory crunch fuels capacity race, schedule pulled 3 months
TL;DR — DIGITIMES (May 18): SK hynix is pulling Yongin Semiconductor Cluster construction forward — first fab ops 3 months ahead, second cleanroom opening ahead of schedule. AI-driven memory demand keeps the supply gap open past 2028, and hyperscaler cloud capex breaking $725B is the direct driver of the capex pull-in.
4. Hanmi Semiconductor crashes 30% in two days — Q1 earnings shock, HBM3E↔HBM4 transition air pocket
TL;DR — Hanmi Semiconductor dropped -16.73% on May 15 and -13.82% on May 18, vaporizing 8 trillion won in market cap (38T → 30T) in a week. 1Q26 OP came in at 84.56 billion won (-87.9% YoY) on revenue of 509 billion won (-65.5%), well short of consensus (revenue 1,900-2,000B / OP 900-1,000B). The cause: HBM3E TC bonder capex has wrapped and HBM4 bonder revenue hasn't ramped — a clean transition air pocket.
5. These chip stocks could extend historic gains by rallying over 110%, according to Nomura — Samsung·SK hynix bull thesis
TL;DR — CNBC (May 19): Nomura pegs Korean memory suppliers' revenue and earnings growth at ~30% annually over the next 3-5 years, with 2026 earnings rising seven- to eightfold. Nomura: 'memory vendors have entered an unprecedented phase of rapid revenue growth and margin expansion in a short period of time.' Bull thesis on Samsung and SK hynix in the AI memory cycle.
