ACIC, American Coastal Insurance Corporation
Insurance — Property & Casualty financial
Our target market in such areas consists of states where the perceived threat of natural catastrophe has caused large national insurance carriers to reduce their concentration of policies.
Collectively, we refer to the holding company and all our subsidiaries, including non-insurance subsidiaries, as "American Coastal Insurance Corporation," which is the preferred brand identification for our Company.
In 2023, our former insurance subsidiary that wrote personal residential business in six states, United Property & Casualty Insurance Company (UPC) was placed into receivership with the Florida Department of Financial Services (the "DFS"), which divested our ownership of UPC.

The business in brief
read the 10-K →What this business is and what moves its needle, from its own SEC filings.
- What moves the needle
- Underwriting discipline and the float. What decides it: whether the combined ratio stays below 100% so the policies make money on their own, how large the float is against equity, and what that float earns once it is invested. On its own account, the filing leans hardest on pricing power & competition, set against the numbers in what the filing emphasizes, below.
- Is it a good business?
- The underwriting result is not cleanly tagged in the filings. Book value per share, the measure Berkshire is judged on, has compounded about −6% a year across the record. The float runs about 0.4× equity, the leverage that magnifies both the underwriting and the investing. Whether the discipline holds through a soft market, and how the float is invested, are what the 10-K decides.
Every line is arithmetic on the company's filings, shown in full in the sections below.

Is it a good business?
- Not enough dataIndustry peers: median 91%
What this means
Premiums or claims weren't found in the filing data.
- Return on equity 34%StrongNet income $107M ÷ equity $318MIndustry peers: median 12%
What this means
What it earns on shareholders' capital, the underwriting result plus what the float earns invested. Durably above the ~10% cost of equity is what compounds book value.
The float
- Float (reserves) $166M0.5× equityLoss and claim reserves $166M, 0.5× equity
What this means
Money held against future claims and invested in the meantime. Buffett's insight was that good underwriting makes this float cost less than nothing, a pool of other people's money the owners earn on. Measured here from loss and claim reserves only; it excludes unearned premiums and funds held, so the true float is somewhat larger than shown. The larger it is against equity, the more that leverage works, for better or worse.
- Investment income $23M13.6% on the floatNet investment income $23M, 13.6% on the float
What this means
What the float and capital earned this year. This is the second engine: an insurer that breaks even on underwriting still wins if the float is large and invested well.
Does AI threaten the moat?
Low contestabilityThe moat is physical, regulated or balance-sheet-funded, the kind AI cuts costs within but does not contest.
In its own filing Framed as a capability
The filing positions AI as something the company uses, not something it fears.
“We also utilize AI technology to assist with the intake process and the underwriting evaluation process (including both guidelines and building characteristics).”
AI is unlikely to contest a moat that is physical, regulated or balance-sheet-funded; here it reads more as a cost tool than a threat, and the company is using it that way.

Management, ownership & pay
read the proxy →From the proxy: how much of the business the people running it own, and how they are paid, beside what the business earned for its owners in the same years.
| Fiscal year | Chief executive | Pay, as filed | “Actually paid” | Owner earnings |
|---|---|---|---|---|
| 2021 | — | $181k | $175k | ($301M) |
| 2022 | — | $162k | $145k | ($176M) |
| 2023 | — | $176k | $215k | ($136M) |
| 2024 | Mr. Dan Peed | $211k | $229k | $243M |
| 2025 | Mr. B. Bradford Martz | $2.8M | $2.7M | $71M |
Both pay figures are the company’s own, from the pay-versus-performance table its proxy statement files. “As filed” is the Summary Compensation Table total: salary, bonus, and equity awards at their value on the day of grant. “Actually paid” is the SEC’s prescribed recalculation, which re-marks those equity awards to what they became as they vested; it can swing far above or below the filed figure in either direction, and negative years occur. Owner earnings are the whole business's, from the record above, for the same fiscal years. A dash under the name means the filing tags the figure without naming the officer.
- Insider ownership49.2%
The stake all directors and executive officers hold together, per the 2026 proxy: skin in the game, the first thing Munger reads.
- Stock-based compensation$4M
The slice of the business handed to employees in shares this year, 1% of revenue, equal to 3% of operating profit. Buffett's oldest accounting fight: this is compensation, compensation is an expense, real whether or not the headline earnings admit it. One trap: the cash-flow statement adds SBC back, so the operating cash, and the owner earnings drawn from it, are flattered by exactly this amount; counted as the cost it is, what an owner keeps is lower.

The price
What a price has to assume.
What the price implies
price / tangible bookAn insurer is worth a multiple of its tangible book value, and the multiple it deserves is set by the return it earns on that book. Type today’s price; we show what you would be paying against what American Coastal Insurance Corporation’s record justifies.
$
The assumptions
Tangible book / share, delivered−10%/yr’20→’25
The justified multiple is (return on tangible equity − growth) ÷ (cost of equity − growth). An insurer earning exactly its cost of equity is worth about one times tangible book; the premium above that prices each point of durable excess return. A higher cost of equity lowers the justified multiple for an insurer.

Graham’s price gate—
Graham applied the same standards to financial enterprises (Intelligent Investor ch.14): the 15× multiple cap on averaged earnings, and P/E times price-to-book at most 22.5. The gate marks the bargain-hunter’s floor, not a verdict.

Tangible book $269M on 48M shares, a 2% normalized return on it. The dials set the multiple such a return would justify; your price sets the multiple you are paying. It assumes the insurer keeps earning that return; an underwriting cycle, a reserve shortfall or a bad year on the float changes it, which is what the record and the 10-K are for.
