Bamboo Insurance’s IPO price range is set, according to an amended prospectus filed with securities regulators this week. The Midvale, Utah-based managing general underwriter, which specializes in AI-driven homeowners coverage, disclosed the range in Amendment No. 1 to its Form S-1 registration statement, alongside the size and structure of the planned share sale. For a sector that has watched relatively few insurtechs reach the public markets in recent years, a priced range is a concrete signal that a listing is drawing closer, rather than merely being contemplated.
Bamboo operates as a managing general underwriter, meaning it designs, prices and distributes homeowners insurance policies on behalf of insurance-company capacity providers rather than carrying the risk on its own balance sheet in the way a traditional insurer does. That asset-light model, paired with the company’s use of artificial intelligence in underwriting and pricing, has positioned Bamboo as one of a handful of MGU-style platforms attempting to prove the model can scale profitably in a property-insurance market that has been volatile for carriers and policyholders alike.
Selling shareholders take pricing range to market
The amendment specifies that existing investors, not the company itself, are the ones selling stock in the transaction: they are offering 35,000,000 shares of Class A common stock. The offering price is estimated to be between $18.00 and $20.00 per share, according to the amended registration statement filed with the SEC. Because the shares are being sold by existing holders rather than the company, Bamboo will not receive any proceeds from the sale of shares by the Selling Stockholders in this offering.
The company has applied to list its shares on the New York Stock Exchange (the “NYSE”) under the symbol “BMB.” A completed listing would give Bamboo’s homeowners-focused underwriting platform a public trading venue for the first time.
Underwriters lead offering that follows August debut
J.P. Morgan Securities LLC and Morgan Stanley & Co. LLC are acting as joint book-running managers of the offering, underwriting the sale on behalf of the selling shareholders. The pricing amendment follows the Form S-1 registration statement Bamboo filed in late August, testing investor appetite for its AI-driven MGU model, rather than marking a fresh filing.
The prospectus also details the company’s ownership history: On January 2, 2024, White Mountains through its wholly owned subsidiaries completed an acquisition of approximately 70% of the then issued and outstanding equity interests of Bamboo Ide8 Insurance Services, giving the insurer its current controlling shareholder.
Estimated price ranges in a registration statement are not final: they give underwriters and prospective institutional investors a working band to gauge demand during the roadshow that precedes pricing, and the eventual IPO price can land inside, above or below that band depending on investor interest. Amendment No. 1 does not specify an exact pricing date or first day of trading, since the registration statement’s effectiveness with the SEC remains pending, so the range published this week is best read as a marker of where the deal currently stands rather than a locked-in outcome.
Prospectus financials show accelerating profitability
For fiscal year 2025, the filing states the company achieved $104 million in Adjusted EBITDA, representing a 38% Adjusted EBITDA margin and year-over-year Adjusted EBITDA growth of 77%. Managed Premium for the same period grew by 58%, according to the prospectus summary section of the filing.
The prospectus summary states: For the six months ended June 30, 2026, we generated net income of $14 million, representing a net income margin of 8%, and revenue of $173 million. Over the same stretch, the company also posted $77 million in Adjusted EBITDA, representing a 45% Adjusted EBITDA margin, and 82% Adjusted EBITDA growth compared to the six months ended June 30, 2025, while Managed Premium climbed by 34% year over year.
Underwriting performance also features prominently in the filing: loss ratios have outperformed the industry by an average of 32 percentage points over the last five fiscal years, the company says.
Taken together, the growth and profitability figures in the prospectus summary are the kind of metrics public-market investors typically weigh most heavily when sizing up an insurtech listing, given how uneven the sector’s earnings performance has been since an earlier wave of insurtech IPOs in the early 2020s. Whether the market ultimately prices Bamboo’s stock toward the top or bottom of its stated range will depend on how underwriters and institutional buyers read those numbers during the roadshow, rather than on anything disclosed in the amendment itself.
| Metric | FY2025 | H1 2026 |
|---|---|---|
| Adjusted EBITDA | $104 million | $77 million |
| Adjusted EBITDA margin | 38% | 45% |
| Adjusted EBITDA growth (YoY) | 77% | 82% |
| Managed Premium growth | 58% | 34% |
| Net income | — | $14 million |
| Revenue | — | $173 million |
IPO lands amid a wider wave of insurtech dealmaking
Bamboo’s pricing update lands amid a busy stretch of capital-markets activity across the insurance-technology sector. It comes shortly after Thoma Bravo agreed to take fellow insurtech Accelerant private, another sign that dealmakers are actively repricing risk-focused technology platforms. The listing also comes as regulators have flagged rising homeowners insurance premiums and non-renewal rates nationally, the exact market Bamboo’s MGU platform underwrites into.
For sector-watchers, the Bamboo pricing amendment offers a live test of investor appetite for MGU-style, technology-driven underwriting platforms at a moment when the broader homeowners insurance market is under visible strain. A successful NYSE debut at or near the top of the stated range would give other privately held insurtechs a fresh data point for their own listing plans; a weaker reception would reinforce how selective public-market investors remain toward the space. Either way, the amendment moves Bamboo from the exploratory stage of its August filing into the final mechanics of an actual public offering, with the underwriters now responsible for building the order book that will determine where inside the range the stock ultimately prices.
