Micron Swings as Taiwan Workers Vote to Authorize a Strike

Micron shares swung hard on Wednesday after union members at the company’s Taoyuan plant in Taiwan voted to authorize a strike over how the memory maker shares its profits. The stock fell more than 2.5% in the morning. Then it reversed. By early afternoon it was trading near $1,085, up 3.8% from Tuesday’s close of $1,045.56. With hours left in the session, the day’s direction was still unsettled.

What the vote actually said

The tally was lopsided. The union said 1,994 members, or 99% of those who cast ballots, backed strike authorization after a second round of mediation broke down. Officials have not set a walkout date, and talks with the company remain open, so the vote clears the way for a strike without starting one. At issue is a demand that Micron commit permanently to routing 15% of operating profit into quarterly bonuses. The company had put forward a fiscal-2026 package the union pegged at the equivalent of 35 to 68 months of base pay, which members turned down.

Why a Taiwan walkout would matter

The timing is what lifts this above a local labor story. Taiwan is Micron’s main production base. The company fabricates a large share of its memory there, including the high-bandwidth memory that artificial-intelligence accelerators depend on. Micron’s Taiwan unions, which cover the Taoyuan and Taichung sites, together represent close to 10,000 of its 15,000 workers on the island. A sustained stoppage at that scale would hit while DRAM and high-bandwidth memory supply is already stretched, according to industry coverage of the dispute.

Why the stock did not simply fall

That backdrop helps explain the reversal. A disruption that threatens Micron’s own output can, at the same time, tighten a market where buyers are already competing for parts, and some analysts read a Taiwan supply shock as a mixed event for a memory maker rather than a clean negative. The bullish case got louder last week. D.A. Davidson’s Gil Luria lifted his price target to $2,100 from $2,000, the highest on Wall Street, and kept a buy rating after Micron’s September 30 results. His argument is that AI demand for high-bandwidth memory extends the current upcycle well past the industry’s usual two-to-three-year rhythm, aided by multiyear fixed-price supply contracts. The same note concedes the catch: pricing has to hold near peak levels for the math to work.

Calmer than the one-day tape

Step back from the intraday tape and the stock looks steadier. Micron closed Tuesday down 1.73%. It is up 2.8% over the past month and close to 1% over three months, and Tuesday’s volume ran a shade below its 20-day average. Even after Wednesday’s bounce, the shares sit roughly 17% under their 52-week high of $1,255.

On the calendar

Two things will shape what comes next. The first is whether the union sets an actual strike date or holds the mandate as leverage to reopen negotiations. The second is Wednesday’s close, which will show how investors weighed an output risk against a tighter supply picture. Broader chip sentiment is soft: U.S. stock indexes slipped from record highs as Treasury yields and oil climbed.
