• 2003: Iordanou became CEO, replacing co-founder and first chief Peter Appel
• 2015: Arch entered mortgage insurance by forming Arch Mortgage Guaranty
• 2016: Arch acquired AIG’s United Guaranty for $3.4 billion, a major expansion
• 2018: Marc Grandisson was named CEO, following Iordanou’s retirement from the role
• 2022: Arch Capital was added to the S&P 500 Index
• 2024: the firm completed its MidCorp and entertainment insurance acquisition from Allianz
