Bamboo Insurance Services has launched the roadshow for its planned initial public offering, setting a price range for the first time and moving the listing into an active process.
The company is offering 35 million shares of Class A common stock at $18 to $20 each. All of them are secondary shares, sold by CVC Capital Partners and White Mountains Insurance Group. Bamboo itself will receive none of the proceeds. CVC acquired a controlling stake in December 2025 in a deal that valued Bamboo at $1.75 billion. White Mountains, which retained roughly a 15 percent stake after that transaction, is also selling. Bamboo has applied to list under the ticker "BMB" on the New York Stock Exchange.
The offering is entirely secondary. CVC and White Mountains are selling existing stakes. Bamboo itself receives none of the proceeds.
That does not mean its capacity commitments are at risk. The company manages nearly $900 million in premium and reported $173 million in revenue for the first half of 2026, up 40 percent from $124 million a year earlier, according to its S-1 filing with the Securities Exchange Commission (SEC). Net income fell to $13.8 million in H1 2026 from $23.7 million in H1 2025, as margins compressed alongside rapid top-line growth. Once public, those numbers face quarterly scrutiny from investors who did not back the company in private - a different set of pressures on underwriting decisions than Bamboo has faced to date.
Bamboo built its business in a market where admitted options for brokers have been shrinking. California represented approximately $18 billion in annual homeowners premiums in 2025, based on S&P Global data cited in the S-1. Major carriers have been pulling back under years of wildfire loss pressure.
Commissioner Ricardo Lara's Sustainable Insurance Strategy, which took full effect in January 2025, allows admitted insurers to use forward-looking catastrophe models and reinsurance costs in rate filings. In exchange, they must expand coverage in wildfire-distressed areas. Bamboo added $150 million in admitted homeowners and dwelling fire capacity across California in July through a partnership with MS Transverse Insurance Company.
Bamboo is not alone in moving toward public markets. Orion180 Insurance Group, a Florida-based E&S homeowners insurer, launched its own roadshow earlier this month and is targeting a Nasdaq listing. Orion180 retains underwriting risk through its own fronting carriers, while Bamboo passes the capital requirement to a panel of third-party fronting carriers. Both are betting that public investors will pay a premium for residential property capacity as the admitted market keeps contracting in catastrophe-exposed states.
Bamboo's roadshow is expected to price within days. At the $19 midpoint, the 35 million shares on offer would generate roughly $665 million in gross proceeds. All of it goes to CVC and White Mountains, not to Bamboo's balance sheet.
