• Quarterly GAAP net income of $90 million and net income per diluted share of $1.33
• Quarterly Adjusted EBITDA of $237 million and Non-GAAP net earnings per diluted share of $2.15, above the midpoint of guidance

"MKS delivered revenue and adjusted EBITDA above the midpoint of our outlook, closing out 2024 on an impressive note against a mixed demand backdrop,” said John T.C. Lee, President and Chief Executive Officer. "Our broad and deep technology portfolio serving an array of semiconductor, electronics and industrial applications enables us to address key demand opportunities as broader end market recovery begins to develop.”

Mr. Lee added, "We enter 2025 in a strong position, highlighted by increasing customer engagement with our World Class Optics solutions, as well as solid trends in our chemistry business as we demonstrate the pivotal role we play in advanced electronics.”

"Our revenue and profitability remained robust in the fourth quarter as our team executed well,” said Ram Mayampurath, Executive Vice President, Chief Financial Officer and Treasurer.

Mr. Mayampurath added, "We delivered continued healthy gross margin, earnings per share growth and increased operating cash flow in 2024. This underscores the value customers see in our technology portfolio as well as our strong focus on both cost management and cash generation. We also continue to make good progress proactively managing our leverage, completing another repricing of our term loan B and making a voluntary principal prepayment of $100 million in January.”
