Mercury General Raises $525M in Debt One Year After Historic California Wildfire Losses

Mercury General Corporation, one of California's largest personal-lines insurers, completed a $525 million bond sale this month and received a formal credit rating on that debt from AM Best on June 24, 2026. The rating agency assigned a Long-Term Issue Credit Rating of 'bbb' (Good) with a stable outlook to the company's 6.25% senior unsecured notes, which mature in June 2036, according to the AM Best press release.

The move is notable because Mercury — which writes home and auto insurance primarily in California — absorbed some of the heaviest losses of any single carrier from the January 2025 Palisades and Eaton wildfires. The company estimated its gross catastrophe losses from those fires at approximately $2.15 billion, making them, in management's words quoted in regulatory filings, 'the most significant catastrophes in Mercury's history.'

How Mercury Is Rebuilding Its Capital Base

Mercury intends to use the proceeds of the new note offering to retire its older senior unsecured notes that were set to come due in March 2027 and to pay down balances under its unsecured credit facility, according to AM Best. By swapping shorter-term debt for a ten-year note, the company extends its repayment horizon and reduces near-term financial pressure.

AM Best noted that financial leverage is expected to remain 'in-line with current rating guidelines' — insurance-industry language indicating the company is not taking on more debt than its capital position can support. Mercury's underlying insurance subsidiaries carry a separate Financial Strength Rating of A (Excellent), which AM Best affirmed in February 2026 after revising the outlook to stable from negative. That A (Excellent) rating reflects AM Best's view of an insurer's ability to meet ongoing obligations to policyholders.

Separately, Insurance Journal reported that reinsurers brought strong risk appetite to Florida's June 1 renewals, a positive signal for the broader catastrophe reinsurance market that companies like Mercury also depend on to limit their exposure to future large losses.

What the Cat Bond Market Is Saying

Mercury has been actively building additional protection through the catastrophe bond market as well. According to Artemis, a specialty publication covering insurance-linked securities, Mercury upsized its second California wildfire catastrophe bond — the Luca Re Ltd. Series 2026-1 — to a target of $125 million to $175 million after initially seeking $100 million. That transaction transfers some of Mercury's potential future wildfire and fire-following-earthquake losses in California to capital-market investors rather than traditional reinsurers.

The combination of the bond offering, the cat bond, and AM Best's stable-outlook ratings paints a picture of a carrier actively working to shore up its finances after an extraordinary loss year — though, as AM Best's rating language cautions, the company's leverage position warrants continued monitoring.
