Micron's Taiwan Unions Want Profit Sharing; Mediation Failed

Micron stock is up about 252% in 2026.

Most of that production physically happens in Taiwan: a majority of fiscal 2025 DRAM output came from the island. Micron has invested roughly $43.9 billion there and employs about 15,000 people.

Around 10,000 of them belong to two unions, in Taoyuan and Taichung.

According to Reuters, the first formal mediation session with the Taoyuan union ended without an agreement on September 4.

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 scheme is the Incentive Pay Plan: an annual target, payout up to twice it, a ceiling of roughly five months of salary. Actual payouts have run well below, at about 2.6 months.

The model the unions want comes from Korea: Samsung's semiconductor division sets aside 10.5% of divisional operating profit, SK Hynix 10%. Taiwan has precedents too — TSMC distributes 4.7% of net profit, Macronix 15%.

The demand is 15% of operating profit from fiscal 2027, paid quarterly rather than once a year.

The bars do not all measure the same thing: TSMC and Macronix compute off net profit, the Korean firms off operating profit.

But the argument is not about the percentage: in Micron's formula the base is not profit at all. It is salary.

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

Most of a memory fab's cost is fixed before the chip's selling price is known, so almost all of a price increase stays on the profit line.

Wages sit inside that 14.2%.

Fifteen percent of operating profit would have been $326 million in fiscal Q3 2025; in the same quarter of fiscal 2026 it is $5.00 billion. The profit-linked formula multiplied by 15.3; the salary-linked one, capped at five months in both years, did not move.

Where 83 Months Comes From

The one-off demand follows the same arithmetic: $5.00 billion divided among 15,000 Taiwan employees is roughly $333,000 per person for three months.

Spread over a year, a request equal to 83 months — close to seven years of salary — sits inside that order of magnitude. How the unions arrived at 83 has not been published.

Micron has a number of its own: the fiscal 2026 bonus will be "the highest in the company's history," details in October.

That is a record inside the formula, not a change to it: the ceiling is still 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, for Taoyuan only. No ballot date has been announced.

The Other Side

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%.

A profit-linked formula would have paid nothing that year.

In Korea the symmetry is written into the contract. SK Hynix pays 60% of this year's bonus in shares, and up to 3% of wages can be deferred in loss-making periods. No comparable downside term has surfaced in the Taiwan demands.

The price of profit sharing is standing by the formula when the profit is gone. See How to Read an Earnings Report.

What a Strike Would Change

All of Micron's 2026 and 2027 HBM — high-bandwidth memory — output is already committed under binding agreements. A disruption has nowhere to be made up.

Orders cannot be moved to Samsung or SK Hynix on short notice. HBM depends on calibrated equipment and years of operator experience, and their lines are full under their own contracts.

So a work stoppage in Taiwan would reach the delivery schedules for Nvidia accelerators.

For comparison, the broad technology index across the same window:

The share reaction has been contained: Micron fell 2.6% on September 1 and about 1% premarket the next day.

The mean target across 41 analysts sits near $1,474; the market is not yet pricing this as a binding production risk. See What Is Valuation?.

What Is Left

The mid-September session and the Taichung union's separate process — September 4 covered only Taoyuan.

Whether a secret-ballot date is actually announced.

And 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.

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.
