GrafTech International To Close Its Graphite Electrode Manufacturing Facility In Monterrey, Mexico; Monterrey Facility Production Expected To Conclude Early In Q2 2027; Expects Annual Capital Expenditure Requirements To Decrease By $5M Beginning In 2027; Expects Total One-Time Cash Costs Of $20M-$25M, Majority By End Of 2027

Company’s long-term earnings and cash flow potential. The Company currently estimates that the closure will result in:

• A reduction in GrafTech’s annual graphite electrode production capacity of approximately 51thousand metric tons, bringing annual production capacity to approximately 127 thousand metric tons from approximately 178 thousand metric tons currently, reflecting:
  • The closure of the Monterrey facility, which has approximately 35 thousand metric tons of annual graphite electrode capacity, and
  • An approximately 16 thousand metric ton reduction in the annual graphite electrode capacity of the Pamplona facility reflecting the change in its production mix to support the Company’s full pin stock requirements;
• Annual cash cost savings of approximately $20 million to $25 million, excluding the impact of one-time costs, with the full benefit expected to be realized in 2028;
• A reduction in annual capital expenditure requirements of approximately $5 million beginning in 2027, reflecting the Company’s reduced manufacturing footprint;
• A one-time release of working capital of approximately $20 to $25 million, with the majority of the benefit expected to be realized in 2028; and
• Total one-time cash costs of approximately $20 to $25 million, consisting primarily of severance and employee-related costs, equipment relocation costs and other facility closure expenses, with the majority of the cash expenditures expected to occur by the end of 2027.
