Berkshire's balance sheet buys GUARD a stable outlook

AM Best moved the five member companies of Berkshire Hathaway GUARD Insurance Companies to a stable outlook from negative, affirming the group's A+ (Superior) financial strength rating and "aa-" issuer credit ratings in an action dated August 12. The companies—AmGUARD, EastGUARD, NorGUARD, WestGUARD and AZGUARD—share results under an intercompany pooling agreement, so the outlook and affirmation apply identically across the pool. The stable sticker ends a negative outlook that had been in place for about a year.

That negative outlook followed underwriting losses in 2023, 2024 and 2025, including material reserve strengthening in commercial auto and business owners policies, the lines where the deepest damage sat. GUARD responded by exiting its admitted personal lines business entirely, re-underwriting the commercial auto and BOP books, and installing an almost entirely new senior leadership team to restore operating performance to previously adequate levels. AM Best now cites two factors for the improved outlook: continued explicit and implicit financial support from immediate parent National Indemnity Company, a Berkshire Hathaway subsidiary, and early positive results from the underwriting corrections. The new team was brought in specifically to reverse the deterioration, and the agency treats those early results as one of the two supports for the revised outlook.

What did not change matters as much as what did. The A+ rating held through three straight years of losses, a durability that is the Berkshire effect—a parent balance sheet absorbing what underwriting could not. The outlook shift to stable is AM Best's judgment that the trajectory is turning, but the turn remains incomplete. The agency says it will keep watching GUARD's performance against peer benchmarks and warns that further rating action remains possible if results do not track. The affirmation itself is the same Superior capital strength that carried GUARD through the loss years; the outlook now points in a better direction.

For agents and brokers with GUARD-placed commercial auto or BOP business, the outlook revision is the more meaningful move: it is AM Best seeing credible evidence that the underwriting problems are being addressed rather than continuing to deteriorate. The agency has left the watch on, and the test is whether the corrected books produce under their own loss ratios. Parent support absorbs a bad year, but pricing a poorly underwritten book back to health is underwriting's work. That same demand for underwriting discipline echoes the test AM Best has flagged for the 2027 reinsurance renewals, as this publication has reported. For a pool whose outlook had been negative for a year, the stable sticker resets the near-term capital narrative—but only until the next results test the re-underwritten books.
