ing Pronouncements Not Yet Adopted

In November 2024, the FASB issued ASU No. 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses”. This ASU requires disclosure, in the notes to the financial statements, of specified information about certain costs and expenses. The amendments in this ASU are effective for annual reporting periods beginning after December 15, 2026, and interim periods within annual reporting periods beginning after December 15, 2027. As this guidance relates solely to financial statement disclosures, the adoption of ASU 2024-03 will have no impact upon the Company’s results of operations, financial condition, or liquidity.

Other accounting pronouncements were issued during the year ended December 31, 2024 which were either not applicable to the Company or did not impact the Company’s consolidated financial statements.

#### Segment Reporting
The Company manages its underwriting operations as twobusiness segments: Aspen Re and Aspen Insurance. The Company has determined its reportable segments by taking into account the manner in which the Company’s chief operating decision maker (“CODM”) makes operating decisions and assesses operating performance. The Company’s CODM is the Group Executive Committee, which comprises global heads of key functions and other key business leads.

Profit or loss for each of the Company’s business segments is measured by underwriting income or loss. Underwriting profit is the excess of net earned premiums over the sum of losses and loss expenses, acquisition costs and general and administrative expenses. Underwriting income or loss provides a basis for the CODM to evaluate the segment’s underwriting performance.

Reinsurance Segment. The Reinsurance segment consists of property catastrophe reinsurance, other property reinsurance, casualty reinsurance and specialty reinsurance.

Insurance Segment. The Insurance segment consists of first party insurance, specialty insurance, casualty and liability insurance, financial and professional lines insurance and other insurance. The other insurance business line includes Aspen Underwriting Limited’s participation as a corporate member in Carbon Syndicate 4747, and the Company’s digital follow capacity offered through Ki’s Lloyd’s platform.

Non-underwriting Disclosures. The Company provides additional disclosures for corporate and other (non-operating) income and expenses. Corporate and other income and expenses include: corporate expenses, non-operating expenses, net investment income, net realized and unrealized investment gains or losses, changes
