UMC stock gets October sales boost as revenue rises 18.33%

United Microelectronics Corporation reported higher consolidated sales for October on Thursday, November 5, 2026. Business Wire carried the company announcement, which showed revenue growth both for the month and for the first ten months of the year.

## October sales gain momentum

UMC's October revenue rose 18.33% year on year to NT$25,197,532 thousand from NT$21,294,974 thousand. Consolidated sales for January through October reached NT$229,207,213 thousand, compared with NT$197,038,628 thousand in the same period of 2025, an increase of 16.33%.

The figures are unaudited and reported in thousands of New Taiwan dollars. They provide a monthly indication of demand across UMC's foundry activities, but they do not by themselves establish the profitability of the period or determine how much of the sales increase will flow through to earnings.

## Mature chips remain strategic

UMC is positioned in specialty and mature-node manufacturing, where demand from connectivity, automotive, power-management and other electronic applications supports utilization. The company is also targeting demand linked to artificial intelligence infrastructure, including supporting chips and related technologies.

That strategy gives the sales trend a wider investment context. Higher revenue can support capacity expansion, while the planned addition of manufacturing capacity also increases the importance of execution, equipment availability and pricing discipline. The October release itself did not provide a new earnings forecast.
