Taoyuan union plans one-day solidarity strike on 22 Oct, CXMT's third-quarter report shows the scale and profit of a real rival…
Labour tensions in Taiwan are escalating. On 19 Oct the Taoyuan union set a specific strike date for the first time (a one-day solidarity strike on 22 Oct), moving from authorisation to action, which would make it the first actual strike in Taiwan's semiconductor industry. The key is the Taichung mediation on 22 Oct.

If talks break down, Taichung (the largest site, with about 11,000 people) could go to a strike vote and become a real supply-side risk. CXMT is expected to report first-three-quarter revenue of RMB 265-270 billion (up 726% to 742% YoY) and net profit of RMB 131.0-132.5 billion, a net margin of about 49%. That is roughly 30% of Micron's full-year FY26 revenue. It shows that the price rises reflect shortages across the industry (positive), but CXMT's ample firepower for capacity and R&D will erode share in commodity DRAM (negative). HBM is still beyond CXMT's capability, so Micron's core profit pool is not yet threatened. At 8am Mountain Time on 21 Oct (10pm Singapore time on 21 Oct) Micron holds a technology roadmap webinar presented by CTO Scott DeBoer, addressing two competitive questions: CXMT's 4F² and the standardisation of NVIDIA's NVHBM.
Key evidence
- Lin Zherui, chairman of the Taoyuan union, announced at a rally in Taipei on 19 Oct that on Thursday 22 Oct, the day of the Taichung union's second labour mediation, Taoyuan will strike for one day in solidarity, demanding that the company put forward a specific profit-sharing plan (China Times, Newtalk, Taiwan People News).
- What has changed: last week the union was still stressing that the Taipei rally was not a strike, and it has now set a specific strike date for the first time, moving from authorisation to action.
- A one-day stoppage has limited direct impact on output, but it would be the first actual strike in Taiwan's semiconductor industry. The key is whether the Taichung mediation on 22 Oct breaks down.
- The Taichung site, the largest, has about 11,000 people, and only a strike vote there would be a real supply-side risk.
- Micron accounts for a little over 20% of global DRAM capacity, and any disruption is magnified in the current shortage.
- CXMT's revenue for the first three quarters of 2026 is expected to be RMB 265-270 billion (RMB 32.08 billion a year earlier, up 726% to 742%). Net profit attributable to shareholders is expected to be RMB 131.0-132.5 billion (a loss of RMB 5.28 billion a year earlier), a net margin of about 49%.

- CXMT's chairman announced on 16 Oct a proposal for a share buyback of up to RMB 2 billion.
- Scale comparison: CXMT's first-three-quarter revenue is about 30% of Micron's full-year FY26 revenue ($133.19 billion).
- Two sides. Positive: Chinese makers are also making huge profits, which shows that the price rises reflect a shortage across the whole industry rather than pricing power unique to Micron, and gives third-party confirmation of the strength of the cycle. Negative: CXMT has ample firepower for capacity expansion and R&D, so the erosion of share in commodity DRAM (especially in the China market) over the medium to long term is real.
- HBM is still beyond CXMT's capability for now, so Micron's core profit pool is not yet threatened.
- Several media outlets point out that CXMT's Q3 profit growth QoQ slowed markedly, which needs confirming by the formal quarterly report.
- Micron announcement of 19 Oct: a technology roadmap webinar will be held at 8am Mountain Time on 21 Oct (10pm Singapore time on 21 Oct), presented by president and CTO Scott DeBoer, covering multi-generation roadmaps for DRAM, HBM and NAND, joint design with customers and long-term research.
- What to watch: the timetable for DRAM nodes after 1γ, custom HBM4E and HBM5 solutions, and more details on edge inference memory. Management choosing this moment to talk about technology is itself a response to competitive worries.
Catalysts to watch
- One-day solidarity strike in Taoyuan on 22 Oct and the outcome of the second labour mediation in Taichung (if talks break down, there is a risk of a strike vote in Taichung)
- Micron technology roadmap webinar on 21 Oct (10pm Singapore time on 21 Oct)
- CXMT's formal Q3 report, confirming how far profit growth slowed QoQ
- Whether the Taichung site of 11,000 people goes to a strike vote
Risks
- A strike in Taichung would be a real supply-side disruption, magnified by Micron's share of over 20% of global DRAM in a shortage
- CXMT has ample firepower for expansion, which over the medium to long term erodes share in commodity DRAM, especially in China
- NVIDIA's standardisation of NVHBM weakens Micron's custom-design moat
- The CXMT 4F² narrative keeps advancing (the timetable for mass production at specific nodes is still unclear)
