I am grateful to Gina for all her good work, leading Afton through some very challenging times. During her tenure as President, we have seen an incredible string of unusual events: fires and freezes at our suppliers’ plants which caused unprecedented supply disruption; the worldwide Covid pandemic; ongoing supply chain challenges from the pandemic; and more recently, inflation, war and sanctions. Throughout this time, she has provided calm, steady leadership that has allowed Afton to prosper and grow.”

Mr. Gottwald continued, “the entire NewMarket, Afton and Ethyl family are fortunate to have had Gina’s dedicated leadership for these many years.”

The Company also announced that Brian D. Paliotti will succeed Gina Harm as President of Afton, effective January 1, 2023. Mr. Paliotti has worked for NewMarket since 2008 serving in a variety of finance roles, most recently as Vice President and Chief Financial Officer.

Mr. Gottwald commented, “I am extremely excited about this opportunity for Brian. Throughout his time with our Company, Brian has focused on building teams, developing people, and pursuing cost-savings initiatives. He has extensive market knowledge, a strong financial background, and an energetic, results-oriented leadership style that will lead us into the future. Brian will remain focused on executing our short and long term plans in pursuit of our objectives, and we can look forward to our continued success under his direction.”
