Micron's Taiwan Unions Want Profit Sharing; Mediation Failed

The memory price cycle has been the running story for a year: contract prices climbed, Micron posted record after record, and the stock is up about 252% in 2026. Most of that output physically happens in Taiwan. A majority of the company's fiscal 2025 DRAM production came from its plants on the island, where Micron has invested roughly $43.9 billion and employs about 15,000 people.

Around 10,000 of those workers belong to two unions, based in Taoyuan and Taichung. In August the unions ran an online survey of their members; more than 80% of those who took part backed strike action. On September 4, the first formal mediation session between Micron and the Taoyuan union ended without an agreement, according to Reuters.

This is not a wage dispute. What the unions want changed is what the bonus is tied to.

Two Formulas, Two Different Worlds

Micron's existing scheme is the Incentive Pay Plan. An annual target is set, payout can reach twice that target, and the ceiling works out to roughly five months of salary. Actual payouts have run well below the ceiling, at about 2.6 months.

The system the unions want comes from Korea. Samsung's semiconductor division, after a long collective-bargaining fight, sets aside 10.5% of divisional operating profit for bonuses. At SK Hynix the figure is 10% of operating profit. Taiwan has its own precedents: TSMC distributes 4.7% of net profit and Macronix 15% of net profit. Micron's unions want 15% of operating profit set aside from fiscal 2027, paid quarterly rather than once a year.

These bars do not all measure the same thing: TSMC and Macronix compute off net profit, Samsung and SK Hynix off operating profit. Net profit is what remains after tax and financing costs, so the same percentage buys less money. The comparable part is this: in Micron's formula, the base is not profit at all. It is salary.

The Mechanism: Profit Rose 15-Fold While Costs Rose 14%

At the top of a cycle, what a percentage is taken from decides everything.

Most of a memory fab's cost is fixed before the selling price of the chip is known: the building, the tools, the depreciation, the core headcount. When prices rise, almost all of the increase stays on the profit line. Wages sit inside that 14.2%.

Now run both formulas across those same two quarters. Fifteen percent of operating profit would have been $326 million in the third quarter of fiscal 2025; in the same quarter of fiscal 2026 it is $5.00 billion. Under a salary-linked formula, the ceiling is five months of pay in both years and moves only with wage increases. The profit-linked formula multiplied by 15.3; the salary-linked one did not move. That divergence is what the unions brought to the table.

Where 83 Months Comes From

The one-off demand follows the same arithmetic. Fifteen percent of operating profit is $5.00 billion in a single quarter. Divided among 15,000 Taiwan employees, that is roughly $333,000 per person for three months. Spread over a year the figure runs to multiples of an engineer's annual pay, and a request equal to 83 months — close to seven years of salary — sits inside that order of magnitude. Published reports do not set out how the unions arrived at 83; but the arithmetic explains why a demand of that size is on the table at all.

Micron has a number of its own. The company said the fiscal 2026 bonus will be "the highest in the company's history," with details to be announced in October. That is a record inside the existing formula, not a change to the formula. The union objection is precisely that: a record payout under a plan whose ceiling is denominated in salary is still capped at five months.

A Survey Is Not a Strike

Most headlines say 80% back a strike. What that sentence measures is not what makes a strike lawful.

The inconclusive September 4 session satisfies the first requirement, and only for the Taoyuan union. No ballot date has been announced for the second. What exists is not a strike decision but the completion of one of the two steps in front of one.

The Other Side

That last line matters. Micron lost $5.8 billion in fiscal 2023; revenue fell from $30.8 billion to $15.5 billion and the gross margin went from 45.2% to negative 9.1%, meaning chips were sold below cost. A profit-linked formula would have paid nothing that year. In Korea the symmetry is written into the contract: under SK Hynix's arrangement this year, 60% of the bonus is paid in shares and up to 3% of wages can be temporarily deferred during loss-making periods. No comparable downside term has surfaced in the Taiwan demands so far. The price of profit sharing is standing by the formula when the profit is gone.

What a Strike Would Change

All of Micron's 2026 and 2027 HBM — high-bandwidth memory — output is already committed under binding customer agreements. That means a disruption has nowhere to be made up. HBM production depends on through-silicon vias, specifically calibrated equipment and years of accumulated operator experience; orders cannot be moved to Samsung or SK Hynix on short notice, because their lines are full under their own contracts.

A work stoppage in Taiwan would therefore not stay a single company's production problem. It would reach the delivery schedules for Nvidia accelerators and the data-center servers built around them.

The direction of the last three months cannot be pinned to any single headline; memory pricing, earnings expectations and sector news all ran together over that period. For comparison, the broad technology index across the same window:

The share reaction has been contained. Micron fell 2.6% on September 1 and roughly another 1% in premarket trading the next day. Analyst positioning did not change; the mean target across 41 analysts sits near $1,474. So far the market is not pricing this dispute as a binding production risk. For the framework behind that pricing, see What Is Valuation?.

What Is Left

Three concrete things to watch. First, the mid-September mediation session and the Taichung union's separate process — the September 4 session covered only Taoyuan. Second, whether a secret-ballot date is actually announced. Third, September 30: Micron reports its fiscal fourth quarter, guided to $50 billion in revenue at an 86% gross margin. If those figures land, the unions' leverage grows; the bonus details Micron says it will publish in October fall in the same weeks.

Figures here come from Micron's reported quarterly results, Reuters' reporting on the mediation session, and Taipei Times and TrendForce coverage of the union demands. The Korean bonus percentages are drawn from company statements and reported union agreements. The 80% figure comes from the unions' own internal survey and is not an independently verified ballot result; the Taiwan legal requirements follow the published text of the Act for Settlement of Labor-Management Disputes.
