Root Insurance investment case

Root Insurance

Root is a U.S. auto insurance company built around a technology-first underwriting model. Root has a leading telematics based pricing model, where a customers price is determined by their driving behaviour. Root also has a unique aproach to the more traditional non-telematics pricing, where they calculate prices using their proprietary nonlinear cross-correlation based model. Most competitors still use general linear models. Roots nonlinear blackbox model ideally allows Root to acquire good customers, which other companies may overprice, and avoid bad customers, which other companies may underprice. Basic examples where nonlinear pricing gives a big advantage is when a combination of some factors is notably riskier than their sum or when a certain risk factor is negated by a specific detail.

Root distributes through three channels: direct-to-consumer, embedded partnerships with car companies and dealers, and independent agents.

The company went public in October 2020 at a valuation of $35 billion, promptly lost most of that as early growth-at-all-costs strategies produced unsustainable loss ratios, and has since staged a meaningful operational turnaround. Q1 2026 was the most profitable quarter in the company’s history: $35.9 million in net income, a 47% annualised return on equity, and a net combined ratio of 91.4%—down from 95.6% a year earlier and 99.7% in Q4 2025. At just under 0.4% market share in U.S. auto insurance, the gap between where Root is and where it could be is large.

Technology and underwriting

With a lead in both telematics and non-telematics based underwriting Root has a chance to charge lower premiums than traditional carriers to their best customers, attract those customers, and maintain profitability anyway because the risk pool is better.

Root’s telematics opt-in rate among eligible direct business is 82%. Management describes the system as increasingly a “closed loop system capable of rapid decision making and continuous learning”. Each policy written generates more data, which trains the model further. This compounding data advantage is an asset, that cannot be quickly replicated by a carrier that has not been collecting it.

The accident period loss ratio has stayed within management’s 60–65% target range across recent quarters: 57.9% in Q1 2025, 62.8% in Q4 2025, and 58.8% in Q1 2026. This is the number that shows whether the underlying risk selection is working and so far it has been.

Competition

Root’s main traditional competitors are Progressive, GEICO, and Allstate. Progressive is the most relevant benchmark: it has operated a telematics programme (Snapshot) longer than anyone and has the capital to build sophisticated pricing models. MetroMile and Lemonade are the most comparable insurtechs; Lemonade is focused on home and renters insurance more than auto, while MetroMile competed directly in pay-per-mile auto.

Root’s annual revenue of $1.56 billion sits in a market where Progressive generates well over $60 billion. The U.S. motor insurance market is projected to grow from around $532 billion in 2026 to $826 billion by 2031.

Currently Root has a lead in technology, but that lead cannot be expected to last forever. In the meantime however Root should have the capability to increase their market share. Root’s current market share is small enough that capturing even a modest additional slice would represent substantial growth.

Valuation

As of early June 2026:

The multiple the market assigns to Root’s revenue is extremely low relative to both its own growth rate (12.6% YoY revenue, 95.3% YoY earnings) and relative to comparables. It trades below the revenue multiple of traditional carriers, despite posting better earnings growth and a more differentiated product.

Running a reverse DCF at Root’s implied WACC of approximately 20% (elevated due to its high Beta), the current price implies perpetual free cash flow of 2.7% per year. This is difficult to reconcile with a company generating a 23% FCF yield, growing earnings at 95% year-over-year, and posting record profitability.

Growth

Growth in the insurance business carries some fairly unique challanges. Root’s strategy includes prioritizing valuable growth over absolute growth. The easiest customers to get are mostly also the worst customers. Root’s non-linear pricing allows them to offer prices that linear models won’t reach, thus capturing customers other companies misprice with their models while pricing-out the worst customers.

Root’s revenue has grown significantly from $460 million in 2023 to $1.18 billion in 2024 and $1.52 billion in 2025. Policies in force reached 495,429 in Q1 2026, up 9% year-over-year. Partnerships as a percentage of new writings have increased from 33% in Q1 2025 to 46% in Q1 2026, with the partnership channel itself growing 30% year-over-year in Q1 2026.

Root currently enjoys a market leading loss ratio and the combined ratio can be expected to go lower as the company grows, given that loss ratio stays similar, potentially boosting overall margins in the long-term.

The Carvana partnership has reached 200,000 active policies and represents the most developed example of the embedded distribution model. Hyundai Capital America was added in April 2025. Root targets expansion to 100,000 eligible independent agency producers and is entering New Jersey in 2026, targeting nationwide coverage by end of 2027 (currently 36 states, covering 80% of U.S. population).

One tension in the current numbers: while gross premiums earned grew 8% year-over-year to $370 million in Q1 2026, gross premiums written declined approximately 5% year-over-year in the same quarter. Since earned premiums lag written premiums, this creates a potential headwind to future earned premium growth unless writing volumes recover. Management pulled back direct marketing in Q1 2026, citing unfavourable conditions while large carriers run aggressive campaigns—positioning this as tactical rather than structural.

Solvency

Root holds $1.06 billion in cash and short-term investments against $0.20 billion in total debt, producing a substantial net cash position relative to its $0.83 billion market capitalisation. Even this amount of debt is slightly unconventional for an insurance company, and it stems from the times when Root was near bankruptcy. The $0.20 billion long-term debt was recently refinanced at a lower rate, saving roughly $5 million in annual interest expense. The debt is not ideal, and is a potential liability if Roots solvency would come under pressure, but most likely it won’t be an issue to which the recent refinancing at a lower rate also speaks to.

In the latest earning report Root announced stock buybacks. They have also been consistently reducing their reinsurance, which now sits at a low 0.6% of overall volume. Reduced reinsurance allows Root to retain more of their expected profits, at the cost of increased volatility in claim payments. These are conscious decisions, which signal confidence in management, which also both technically increase solvency risk. If we assume the management to be competent, then these decisions definetely seem to have positive undertones saying “We don’t need to be worried about our solvency, which gives us room to increase our revenues through bearing more risk, as well as returning excess capital as shareholders value”.

The net combined ratio of 91.4% in Q1 2026 means Root is generating an underwriting profit: claims and expenses consume $0.914 for each dollar of premium earned. Combined ratios above 100% are where insurance companies destroy capital through their core operations. Root has been consistently below 100% in recent quarters, including the more challenging Q4 2025 at 99.7%.

Unencumbered capital stood at $347 million in Q1 2025 and $314 million in Q2 2025. Annual free cash flow is $190 million on a $0.83 billion market cap. Root meets the regulatory Risk-Based capital (RBC) ratio, which works as a relatively strong assurance towards Roots overall solvency risk being tolerable, since the insurance industry is well regulated and these ratios designed to keep insurance companies capital reserves within safe limits.

Risks

Underwriting success: Root seems to have been able to capture high value customers, while growing at an impressive rate. Such success rests on a technological advantage combined to a good strategy. This kind of profitable growth is

Tail risk of fast growth: Loss ratio of Root has been good despite fast growth, but the tail risk of new contracts is not immediately visible, and could stress the loss ratio in the future if the tail risk becomes realized. This risk is made a bit higher since Root currently has a low amount of reinsurance.

Revenue and GPW divergence: gross premiums written declined 5% year-over-year in Q1 2026 while earned premium grew 8%. The pullback in direct marketing is management’s stated explanation. If the writing volume does not recover as direct conditions improve, the earned premium growth will roll over in future quarters.

Earnings quality: Q1 2026’s record net income included a favourable prior period development (PPD) accounting item. PPD represents reserve releases from prior policy periods and can flatter a single quarter without reflecting ongoing improvement in the underlying business. The net combined ratio improvement is real, but the absolute margin level should be viewed with this in mind.

Competitive erosion: Root’s underwriting edge depends on maintaining a better risk model than competitors. Large traditional carriers are investing in more sophisticated pricing models. The timeline for closing the gap is unclear, but it is not unlimited.

Solvency: The market seems to be including a considerable solvency risk to Root’s price. Although I believe it to be unlikely that Root’s solvency would get tested, this risk cannot be ignored with a fast growing insurance company. Root did once almost go under.
