The report details the progress MKS has made toward the achievement of its key ESG objectives. Highlights include:

• We continued to expand our use of renewable energy in 2024 through strategic procurement of renewable electricity.

These efforts contributed to an overall reduction of 365 metric tons of CO₂e in 2024 compared to 2023, further supporting our commitment to reduce our combined Scope 1 and 2 emissions by 42% by 2030, using 2022 as our baseline, in alignment with Science Based Targets initiative (SBTi) criteria.
