Global reinsurer MS Amlin has reported a standalone net profit after tax of $312 million (£268 million) for the financial year ended 31 December 2025. According to the company’s official media release published under IFRS 17 accounting standards, this figure marks a 79.9% increase from the $173.5 million (£149 million) net profit recorded during the previous financial year.
The financial surge was primarily driven by robust premium expansion, sustained rate movements across specific market segments, and solid performances across most underwriting lines, despite significant global catastrophe activity during the period.
Key Financial Indicators and Underwriting Performance
The reinsurer’s insurance service profit expanded to $357.4 million (£307 million), up from $250.3 million (£215 million) in the prior year. Simultaneously, the company’s net financial result grew to $74.51 million (£64 million) from the previous year’s baseline of $57.04 million (£49 million).
MS Amlin’s core underwriting efficiency metrics also showed significant improvement, with the combined ratio strengthening by 3.2 percentage points. The complete financial performance data, comparing the 2025 results against the previous year’s metrics, is structured in the table below:
| Financial Metric (IFRS 17) | Financial Year 2024 | Financial Year 2025 | Year-on-Year Change (%) / Basis Points |
| Net Profit After Tax | $173.5m (£149m) | $312.0m (£268m) | +79.9% |

(Note: 2024 baseline figures for premiums are derived backwards based on the officially stated 26.9% and 13.3% growth trajectories).
Operational Expansion and Catastrophe Losses
During the 2025 fiscal year, MS Amlin expanded its underwriting footprint by launching a new Lloyd’s sub-syndicate, designated as s1673. This corporate entity was established to support additional underwriting capacity and create new commercial growth opportunities. All risks written under this new sub-syndicate are structured to consolidate directly into the firm’s primary Syndicate 2001.
The fiscal year’s strong underwriting performance was achieved despite absorbing substantial natural catastrophe losses. Most notably, the reinsurer’s portfolio covered claims arising from severe weather events and natural disasters during the year, including the destructive Los Angeles wildfires in the United States.
Corporate Structure and Future Outlook
The declared figures reflect MS Amlin’s standalone operational performance as an integral subsidiary of the Japan-based MS&AD Insurance Group Holdings.
Looking forward into the next trading cycle, the parent group, MS&AD, issued a cautious macroeconomic forecast. The holding company expects insurance revenue to remain broadly stable. However, adjusted profits are projected to decline. This anticipated contraction is attributed to softening pricing conditions across global reinsurance markets and an expected return to more normalised, historical averages for natural catastrophe losses.
