Arch Capital Group Ltd is offering $2 billion of debt in two senior note issuances.

The Bermudian-based insurer and reinsurer, a Class of 2001 start-up that is today a constituent of the S&P 500, announced the pricing for both notes would be between 5 per cent and 6 per cent.

The offering comprises $600 million of 5.25 per cent senior notes due 2036, and $1.4 billion of 5.95 per cent notes due 2056.

The company said some of the proceeds would be used to retire or repurchase debt due this year with an aggregate principal of $500 million and a coupon of 4.011 per cent.

The proceeds will also be used to fund a tender offer announced this week, which will enable Arch to buy back up to $350 million of debt from investors. The offer applies to Arch’s 5.144 per cent senior notes due 2043 and its 5.031 per cent senior notes due 2046.

The balance of proceeds will be used for general corporate purposes, Arch said.

The offering is being led by Wells Fargo Securities, BofA Securities, JP Morgan Securities and Lloyds Securities, as active joint book-running managers. The offering is expected to close on June 9, 2026.
