Micron has paused Taiwan HBM fab construction, Bloomberg reports

In brief

Developing. Last updated 5 November 2026, 16:15 Dubai time (UTC+4).

Bloomberg News reports that Micron Technology has all but halted construction of Fab 11E in Taoyuan, Taiwan, a planned high-bandwidth memory (HBM) and DRAM plant budgeted at US$3 billion to US$4.5 billion and previously due online in 2028, amid a protracted labour dispute. The pause is attributed to people familiar with the matter; Micron has not confirmed a construction halt on the record.

According to Bloomberg, Micron has told Taiwanese officials and a supplier of its plans to suspend construction. Micron's on-record statement does not address Fab 11E. It said Taiwan "plays an important role in Micron's global footprint, and our operations today continue as normal," and that it is "confident in maintaining business continuity for our customers." Talks with the Taoyuan union are ongoing; Micron said it looks forward to reaching an agreement.

What Bloomberg reports

Bloomberg, citing people familiar who asked not to be identified because the deliberations are private, says executives are concerned about mounting uncertainties, including the risk that an agreement with a local labour union could be overturned. Micron secured a deal with the larger of its two Taiwan unions in October, but may need to renegotiate because some employees are balking at the terms, according to those people. Minor safety work is still under way on the Taoyuan site; construction will freeze after that, they added. The plant was to make HBM and DRAM using top-end ASML equipment.

Official responses

Taiwan's Ministry of Economic Affairs did not comment on the reported pause, Bloomberg says, but stated that the government was helping Micron implement investment plans. In a statement to Bloomberg News, the ministry said: "The government supports the legal agreement the company has reached with the union, and will shoulder and share responsibilities with the local government to help resolve the differences and create a win-win outcome." The Taoyuan government told Bloomberg it has not been notified of a suspension, though it hopes Micron and its employees can reach a consensus.

A Reuters item syndicated on Investing.com summarised the Bloomberg report and said Reuters could not immediately verify it; that secondary echo adds no independent confirmation of the pause.

Why it matters

HBM and DRAM remain constrained inputs for AI accelerators and data-centre builds. A reported freeze on a 2028-dated Micron fab does not remove existing Taiwan output, and Micron stresses continuity for customers. For technology leaders, the questions are whether any delay lengthens memory lead times into 2028 and beyond, how Micron reallocates capacity across the United States, Japan and Singapore, and whether labour uncertainty changes the risk premium on Taiwan expansion plans. Watch for an on-record Micron confirmation or denial, progress in Taoyuan union talks, and any MoEA or city notification of a suspension.
