➀ GlobalFoundries has been in contact with UMC regarding a potential merger, exploring a partnership two years ago but without progress.

➁ The proposed merger aims to create a larger wafer fabrication company, ensuring the supply of mature process chips in the US and investing in R&D.

➂ UMC and GlobalFoundries rank fourth and fifth in the wafer fabrication market with 5.5% and 4.7% shares respectively in Q4 2024.

➃ The combined revenue would reach $3.7 billion, potentially surpassing Samsung to become the second-largest wafer foundry after TSMC.

➄ Both companies have complementary process technologies and a production footprint across three continents.

➅ The merger faces challenges such as antitrust reviews by regulatory departments and handling agreements with Intel.

➆ UMC responded to the rumors by stating that there are no ongoing merger cases.

➀ TSMC's revenue in February reached US$7.9 billion, marking an 11% decrease from January but a 43% increase year-over-year.

➁ UMC's February revenue was US$552 million, reflecting an unknown change from the previous month.

➂ The first two months of 2025 saw a 39% increase in revenue for TSMC compared to the same period in 2024.

➀ The Southern Taiwan Science Park has resumed normal operations after a magnitude 6.4 earthquake on January 21st.

➁ TSMC's production lines have largely been restored as of January 23rd, while UMC resumed work on January 24th.

➂ The earthquake caused damage to around 60,000 wafers at TSMC, with an estimated loss of over 3 billion NT dollars (approximately $91.5 million USD).
