Use of Estimates Use of Estimates
The preparation of the consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. On an ongoing basis, the Company’s management evaluates estimates, including those related to contingent assets and liabilities as of the date of the consolidated financial statements as well as the reported amounts of revenue and expense during the reporting period. Such estimates are based on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. All revisions to accounting estimates are recognized in the period in which the estimates are revised. Significant estimates reflected in the Company's consolidated financial statements include, but are not limited to, reserves for loss and loss adjustment expense, reinsurance recoverable on unpaid losses, intangible assets, uncertain tax position and valuation allowance on deferred tax assets.

Segment information
The Company's chief operating decision maker is the Chief Executive Officer. The chief operating decision maker manages the operations, allocate resources, and evaluate financial performance on a company-wide basis. The Company operates in one reporting segment within the United States, Europe, including the United Kingdom, providing insurance products to customers through various sales channels. See Note 24 for additional information.
Cash, cash equivalents and restricted cash
The following represents the Company's cash, cash equivalents and restricted cash as of December 31, 2024 and 2023, ($ in millions).
December 31,
20242023
Cash and cash equivalents$376.0 $264.5 
Restricted cash9.7 7.0 
Total cash, cash equivalents and restricted cash$385.7 $271.5 
Cash and cash equivalents consist primarily of bank deposits and money market accounts with maturities of three months or less at the date of acquisition and are stated at cost, which approximates fair value. The Company's restricted cash primarily relates to insurance policy premiums collected by the Company that it holds in a segregated cash account for transmittal to the underwriting carrier, or settlement of insurance related claims. The Company also has restricted cash relating to security deposits for certain office leases. The carrying value of restricted cash approximates fair value.

Investments
Investments consist of fixed maturity securities and short-term investments. The Company considers all of its fixed maturity securities as available-for-sale and are carried at fair value. Fixed maturity securities consist of securities with an initial fixed maturity of more than one year. Unrealized gains and losses related to bonds are included in accumulated other comprehensive income as a separate component of stockholders' equity. The discount or premium on bonds is amortized using the effective yield method. Short-term investments, which may include commercial paper, certificates of deposit, and fixed maturity securities with an initial maturity of one year or less, are carried at amortized cost, which approximates fair value.
The fair value of bonds is principally derived from market price data for identical assets from exchange or dealer markets and from market observable inputs such as interest rates and yield curves that are observable at commonly quoted intervals. For certain bonds for which market prices are not readily available, if applicable, market values are principally estimated using values obtained from independent pricing services, broker quotes and internal estimates.
Interest income, as well as prepayment fees and the amortization of the related premium or discount, is reported in net investment income. Realized gains or losses on the sale of investments are determined on the basis of specific identification.
The Company continuously monitors the difference between cost and the estimated fair value of its investments. Each reporting period, securities with unrealized losses are reviewed to determine whether the decline in fair value requires the recognition of an allowance for credit losses. Factors considered in the review include (i) current market interest rates, (ii) general financial condition of the issuer, (iii) issuers industry and future business prospects, (iv) issuers past defaults in principal and interest payments, and (v) the payment structure of the investment and the issuers ability to make contractual payments on the investment.

The Company also considers whether it intends to sell the security, or if it is more likely than not that it will be required to sell the security before recovery of its amortized cost. When assessing whether it intends to sell a fixed-maturity security or if it is likely to be required to sell a fixed-maturity security before recovery of its amortized cost, the Company evaluates certain relevant facts and circumstances which may include, but not limited to, business prospects, credit ratings and available information from asset managers and rating agencies for individual securities.
For fixed-maturity securities where a decline in fair value is below the amortized cost basis and the Company intends to sell the security, or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost, a credit-loss charge is recognized in net income based on the fair value of the security at the time of assessment. For fixed-maturity securities that the Company has the intent and ability to hold, the Company compares the estimated present value of the cash flows expected to be collected to the amortized cost of the security. The extent to which the estimated present value of the cash flows expected to be collected is less than the amortized cost of the security and represents the credit-related portion of the impairment, such is recognized in net income through an allowance for credit losses. Any remaining decline in fair value represents the noncredit portion of the impairment, which is recognized in other comprehensive income.

Accrued interest receivable is recorded as a component of accrued investment income on its consolidated balance sheet which is presented separately from available-for-sale securities. The Company does not measure an allowance for credit losses on accrued interest receivable and would instead write off accrued interest receivable at the time an issuer defaults or is expected to default on payments.
Fair value of financial instruments
Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between willing, able and knowledgeable market participants at the measurement date. Fair value measurements are not adjusted for transaction costs. In addition, a three-tiered hierarchy for inputs is used in management's determination of fair value of financial instruments that emphasizes the use of observable inputs over the use of unobservable inputs by requiring that the observable inputs be used when available. Observable inputs are market participant assumptions based on market data obtained from sources independent of the Company. Unobservable inputs are the reporting entity's own assumptions about market participant assumptions based on the best information available under the circumstances. In assessing the appropriateness of using observable inputs in making its fair value determinations, the Company considers whether the market for a particular security is "active" or not based on all the relevant facts and circumstances.
To determine the fair value of its investments, the Company utilizes third-party valuation service providers to gather, analyze and interpret market information and derive fair values based upon relevant methodologies and assumptions for individual instruments.
Valuation service providers typically obtain data about market transactions and other key valuation model inputs from multiple sources and, through the use of widely accepted valuation models, provide a single fair value measurement for individual securities for which a fair value has been requested under the terms of service agreements. The inputs used by the valuation service providers include, but are not limited to, market prices from recently completed transactions and transactions of comparable securities, interest rate yield curves, credit spreads, currency rates and other market observable information, as applicable. The valuation models consider, among other things, market observable information as of the measurement date as well as the specific attributes of the security being valued including its term, interest rate, credit rating, industry sector and, when applicable, collateral quality
and other issue or issuer specific information. When market transactions or other market observable data is limited, the extent to which judgment is applied in determining fair value is greatly increased.
As a basis for considering such assumptions, a three-tier value hierarchy is used in management's determination of fair value based on the reliability and observability of inputs as follows:
Level 1 — Valuations are based on unadjusted quoted prices in active markets that the Company has the ability to access for identical, unrestricted assets and do not involve any meaningful degree of judgment. An active market is defined as a market where transactions for the financial instrument occur with sufficient frequency and volume to provide pricing information on an ongoing basis;
Level 2 — Valuations are based on direct and indirect observable inputs other than quoted market prices included in Level 1. Level 2 inputs include quoted prices for similar assets in active markets and inputs other than quoted prices that are observable for the asset, such as the terms of the security and market-based inputs;
Level 3 — Valuations are based on techniques that use significant inputs that are unobservable. The valuation of Level 3 assets and liabilities requires the greatest degree of judgment. These measurements may be made under circumstances in which there is little, if any, market activity for the asset or liability. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment. In making the assessment, the Company considers factors specific to the asset. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
The Company's fair value measurements include investments, intangible assets, warrants liability and stock options.
Concentrations of credit risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, fixed maturity securities and reinsurance recoverables. Cash and cash equivalents are held with financial institutions of high credit quality, and fixed maturity securities primarily on U.S. government, U.S. government agencies, and high credit quality issuers of debt securities. Cash and cash equivalent balances may exceed the amount of insurance provided on such balances. The Company evaluates the financial condition of its reinsurers, and reinsures its business primarily with highly rated reinsurers, and may retain funds due to reinsurers or require letters of credit as security for those recoverable balances (Note 8).
Premium receivable
Premium receivable is reported net of an allowance for estimated uncollectible premium amounts. Premiums receivable are short-term in nature and due within a year. Allowance is based upon the ongoing review of amounts outstanding, length of collection periods, the creditworthiness of the insured and other relevant factors. Amounts deemed to be uncollectible are written off against the allowance. Allowance for credit losses amounted to $2.8 million as of December 31, 2024 and $2.5 million as of December 31, 2023.
Reinsurance
Reinsurance is used to mitigate the exposure to losses, manage capacity and protect capital resources. Reinsuring loss exposures does not relieve the Company from its obligations to policyholders. Reinsurance recoverable, including amounts related to incurred but not reported claims (“IBNR”) and prepaid reinsurance premium, is reported as an asset. To minimize exposure to losses related to a reinsurer's inability to pay, the financial condition of such reinsurer is evaluated initially upon placement of the reinsurance and periodically thereafter. In addition to considering the financial condition of a reinsurer, the collectability of the reinsurance recoverable is evaluated based upon a number of other factors. Such factors include the amounts outstanding, length of collection periods, disputes, any collateral or letters of credit held and other relevant factors. To the extent that an allowance for uncollectible reinsurance recoverable is established, amounts deemed to be uncollectible would be written off against the allowance for estimated uncollectible reinsurance recoverable. The Company has no historical experience on credit losses from reinsurance recoverables and has not recorded any allowance for uncollectible reinsurance recoverable as of December 31, 2024 and December 31, 2023.
Amounts recoverable from reinsurers are estimated in a manner consistent with the liability associated with the reinsured business and consistent with the terms of the underlying contract.
Ceded premium written is recorded in accordance with the applicable terms of the reinsurance contracts and ceded premium earned is charged against revenue over the period of the reinsurance contracts. Ceded losses incurred reduce net loss and loss adjustment expense incurred over the applicable periods of the reinsurance contracts with third-party reinsurers.
The ceding of insurance does not legally discharge the Company from its primary liability for the full amount of the policy coverage, and therefore the Company will be required to pay the loss and bear collection risk if the reinsurer fails to meet its obligations under the reinsurance agreement. To minimize exposure to significant losses from reinsurance insolvencies, the Company evaluates the financial condition of its reinsurers and monitors concentrations of credit risk.
Prepaid reinsurance premiums represents the unearned portion of premiums ceded to reinsurers. Funds held under reinsurance treaties represent amounts retained by the Company on behalf of the reinsurer based on terms of the reinsurance agreements.
Deferred acquisition costs
Direct acquisition costs, which primarily consist of commissions and premium taxes, related to each policy the Company successfully writes are deferred and amortized to expense in proportion to the premium earned, generally over a period of one year. Deferred acquisition costs are reviewed at least annually to determine their recoverability from future income. If any such costs are determined not to be recoverable they are charged to expense. Anticipated net loss and loss adjustment expense and estimated remaining costs of servicing contracts are considered when evaluating recoverability of deferred acquisition costs. The amount of deferred acquisition costs amortized to income was $30.5 million, $21.8 million, and $17.0 million for the years ended December 31, 2024, 2023, and 2022, respectively, and are included in “Other insurance expense” on the consolidated statements of operations and comprehensive loss.
Property and equipment, net
Property and equipment are stated at cost, net of accumulated depreciation. Depreciation is calculated using the straight-line method over the estimated useful life of the assets at the following rates:
 Years
Computers and electronic equipment3
Furniture and equipment6
Leasehold improvementsShorter of lease term or useful life
Capitalized internal use software
The Company defers certain costs related to the development of internal use software, which are incurred during the application development stage, and amortizes them over the software's estimated useful life. The amounts capitalized include employee payroll and payroll-related costs directly associated with the development activities. The Company's policy is to amortize capitalized costs using the straight-line method over the estimated useful life, which is currently two years, beginning when the software is substantially complete and ready for its intended use. Costs incurred in the preliminary and post-implementation stages of the Company's products are expensed as incurred.
Intangible assets
Intangible assets are recorded at their acquisition date fair values which involves the use of valuation methodologies appropriate for determining the market value of each asset. These valuation methodologies use various assumptions that are inherently subjective. Identifiable intangible assets consist of value of business acquired and technology, which are subject to amortization, and insurance licenses and trademark associated with the Company’s name acquired in 2019, which are not subject to amortization.
Indefinite-lived intangible assets are tested for impairment at least annually, or more frequently if events or such as a change in business circumstances that indicates the carrying value of the assets may not be recoverable. The annual impairment test for indefinite-lived intangible assets may be completed through a qualitative assessment to determine if the fair value of the indefinite-lived intangible assets is more likely than not greater than the carrying amount. The Company may elect to bypass the qualitative assessment, or if a qualitative assessment indicates it is more likely than not that the estimated carrying value exceeds the fair value, the Company will test for impairment using a quantitative process. If the Company determines that impairment of its intangible assets may exist, the amount of impairment loss is measured as the excess of carrying value over fair value. The estimates in the determination of the fair value of indefinite-lived intangible assets include the anticipated future revenues of the Company and the resulting cash flows. There were no circumstances that indicate that the carrying amount of intangible assets deemed to have an indefinite useful life may not be recoverable for the years ended December 31, 2024 and 2023.

Intangible assets subject to amortization are amortized over the estimated useful life and reviewed for impairment when indicators exist.

Goodwill

Goodwill is the excess of purchase price over the fair value of net assets acquired. Goodwill is not amortized, but instead is reviewed for impairment at the reporting unit level on an annual basis, during the fourth quarter, or more frequently if indicators of impairment exist. The annual impairment test for goodwill is initially completed through a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying value. If facts and circumstances determine that it is not more likely than not that a reporting unit fair value is less than its carrying amount, then additional testing of goodwill is not required. However, if the Company determines that it is more likely than not that the fair value of a reporting unit is less than the carrying value, then the Company will perform a quantitative analysis. The quantitative analysis compares the estimated fair value of a reporting unit to its carrying value, including goodwill. If the fair value exceeds the carrying value, there is no impairment on recorded goodwill. However, if the carrying value exceeds the fair value of a reporting unit, an impairment loss will be recognized in the amount of the excess carrying value over fair value limited by the total amount of goodwill for the reporting unit. The Company elected to bypass the qualitative assessment allowed under the guidance and performed a quantitative goodwill impairment assessment during the fourth quarter of 2024, and estimated the fair value of the reporting unit using the income approach, based on the discounted cash flow valuation techniques, and the market valuation approach. Based on the quantitative analysis, the estimated fair value exceeded the carrying value of the reporting unit and concluded that there was no impairment of the recorded goodwill as of December 31, 2024.

Variable Interest
The Company accounts for its variable interest entity (“VIE”) in accordance with Accounting Standards Codification (“ASC”) Topic 810, Consolidation, which requires consolidation of VIEs by the primary beneficiary. A VIE is an entity where the investor lacks certain essential characteristics of a controlling financial interest, which may include a simple majority kick-out rights, or lacks sufficient funds to finance its own activities without financial support provided by other entities. The Company is deemed to have a controlling financial interest when it has both the ability to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. The Company consolidates the VIE in its consolidated financial statements when it is determined to be the primary beneficiary. The Company reassesses its determination of whether the Company is the primary beneficiary of a VIE, upon changes in facts and circumstances that could potentially alter the Company’s assessment.
The Company in 2023 established a captive cell facility at a Bermuda transformer vehicle that is authorized to write and purchase insurance and reinsurance to retain most of the Company’s windstorm exposure (Note 8). Through the Company’s participation interest in this arrangement which is considered a VIE, the Company determined that it is the primary beneficiary of the VIE since it has the power to direct and exercise control over the significant activities and has the obligation to absorb losses or the right to receive residual returns of the VIE. As a result, the Company included the VIE in the consolidated financial statements.
Unpaid loss and loss adjustment expense
The reserves for loss and loss adjustment expense represent management's best estimate of the ultimate cost of all reported and unreported loss incurred through the balance sheet date. Unpaid loss and loss adjustment are based upon the assumption that past developments are an appropriate indicator of future events. The Incurred But Not Reported (“IBNR”) portion of unpaid loss and loss adjustment expense is based on past experience and other factors. The methods of making such estimates and for establishing the resulting reserves are periodically reviewed and updated. Any resulting adjustments are reflected in income. Unpaid loss and loss adjustment expense consists of the estimated ultimate cost of settling claims incurred within the reporting period (net of related reinsurance recoverable), including IBNR claims, plus changes in estimates of prior period losses. The Company reports its unpaid loss and loss adjustment expense on an undiscounted basis.
The estimation of the liability for unpaid loss and loss adjustment expense is inherently complex and subjective, especially in view of changes in the legal and economic environment, which impact the development of unpaid loss and loss adjustment expense, and therefore quantitative techniques frequently have to be supplemented by subjective considerations and managerial judgment. In addition, trends that have affected development of liabilities in the past may not necessarily occur or affect liability development to the same degree in the future. Therefore, there can be no assurance that the ultimate liability will not materially differ from amounts reserved with a resulting material effect on the operating results of the Company.
The unpaid loss and loss adjustment expense estimate is generally calculated by first projecting the ultimate cost of all claims that have been incurred and then subtracting reported losses and loss adjustment expenses. Reported losses include cumulative paid losses and loss adjustment expenses plus case reserves. Therefore, the IBNR also includes provision for expected development on reported claims.
The Company's actuarial analysis of the historical data provides the factors the Company uses in its actuarial analysis in estimating its loss and loss adjustment reserves. These factors are measures over time of claims reported, average case incurred amounts, case development, severity and payment patterns. However, these factors cannot be directly used as they do not take into consideration changes in business mix, claims management, regulatory issues, and other subjective factors. The Company uses multiple actuarial methods in determining its estimates of the ultimate unpaid claim liabilities. Each of these methods require judgment and assumptions. The methods can include, but are not limited to:
Paid Development Method — uses historical, cumulative paid losses by accident year and develops those actual losses to estimated ultimate losses based upon the assumption that each accident year will develop to estimated ultimate cost in a manner that is analogous to prior years.
Paid Bornhuetter-Ferguson Method — a combination of the Paid Development Method and the Expected Loss Method, the Paid Bornhuetter-Ferguson Method estimates ultimate losses by adding actual paid losses and projected future unpaid losses. The amounts produced are then added to cumulative paid losses to produce the final estimates of ultimate incurred losses.
Incurred Development Method — uses historical, cumulative incurred losses by accident year and develops those actual losses to estimated ultimate losses based upon the assumption that each accident year will develop to estimated ultimate cost in a manner that is analogous to prior years.
Incurred Bornhuetter — Ferguson Method — a combination of the Incurred Development Method and the Expected Loss Method, the Incurred Bornhuetter-Ferguson Method estimates ultimate losses by adding actual incurred losses and projected future unreported losses. The amounts produced are then added to cumulative incurred losses to produce an estimate of ultimate incurred losses.
Expected Loss Method — utilizes an expected ultimate loss ratio based on historical experience adjusted for trends multiplied by earned premium to project ultimate losses.
For each method, losses are projected to the ultimate amount to be paid. The Company then analyzes the results and may emphasize or de-emphasize some or all of the outcomes to reflect actuarial judgment regarding their reasonableness in relation to supplementary information and operational and industry changes. These outcomes are then aggregated to produce a single selected point estimate that is the basis for the actuary's point estimate for loss reserves.
Contingent liabilities
The Company accounts for its contingent liabilities in accordance with ASC Topic 450, Contingencies (“ASC 450”). A provision is recorded when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. With respect to legal matters, provisions are reviewed and adjusted to reflect the impact of negotiations, estimated settlements, legal rulings, advice of legal counsel and other information and events pertaining to a particular matter.
Comprehensive loss
Comprehensive loss includes net loss as well as other changes in stockholders' equity that result from transactions and economic events other than those with stockholders.
Employee related obligations
The Company established a defined contribution savings plan under Section 401(k) of the Internal Revenue Code for employees based in the United States. This plan covers substantially all employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis. Company contributions to the plan may be made at the discretion of the Company's board of directors. The matching contributions made by the Company amounted to $2.6 million, $2.6 million and $2.2 million for the years ended December 31, 2024, 2023 and 2022, respectively.

Revenue
Premium is earned on a pro-rata basis over the term of the related insurance coverage. Unearned premium and prepaid reinsurance premium represent the portion of gross premium written and ceded premium written, respectively, related to the unexpired terms of related policies. Premium ceded to third party reinsurers is reported as a reduction of earned premium.
A premium deficiency is recognized if the sum of expected loss and loss adjustment expense, unamortized acquisition costs, and policy maintenance costs exceeds the remaining unearned premium. A premium deficiency would first be recognized by charging any unamortized acquisition costs to expense to the extent required to eliminate the deficiency. If the premium deficiency were greater than unamortized acquisition costs, a liability would be accrued for the excess deficiency. The Company does not consider anticipated investment income when determining if a premium deficiency exists. There was no premium deficiency as of December 31, 2024 and 2023.
Ceding commission income represents commission received based on premium ceded to third-party reinsurers to reimburse us for acquisition and underwriting expenses. Commissions on reinsurance premium ceded is recorded as earned consistent with the recognition of earned premium on the underlying insurance policies, on a pro-rata basis over the terms of the policies reinsured. The portion of ceding commission income which represents reimbursement of successful acquisition costs related to the underlying policies is recorded as an offset to other insurance expense.
Net investment income represents interest earned from fixed maturity securities, short term securities and other investments, and gains or losses from sale of investments. Investment income is recorded as earned. Investment income consists primarily of interest income which is recognized on an accrual basis. Net investment income represents investment income, net of investment fees paid to the Company’s investment manager and other investment expenses.
Commission income consists of commissions earned on policies written on behalf of third-party insurance companies where the Company has no exposure to the insured risk. Such commission is recognized on the effective date of the associated policy which is when the performance obligation is completed.

Other income consists of fees collected from policyholders relating to installment premiums, and are recognized at the time each policy installment is billed. Other income also includes net realized gains or losses from sale of investments, interest income and sublease income (Note 22).
Other insurance expense
Other insurance expense consists of the amortization of deferred acquisition costs, which includes commissions and premium taxes incurred on the successful acquisition of business written on a direct basis, and merchant processing fees. Other insurance expense also includes employee compensation, including stock-based compensation and benefits, of the Company's underwriting teams, as well as allocated occupancy costs and related overhead costs based on headcount.
Sales and marketing
Sales and marketing includes third-party marketing, advertising, branding, public relations and sales expenses. Sales and marketing also includes associated employee compensation, including stock-based compensation and benefits, as well as allocated occupancy costs and related overhead based on headcount. Sales and marketing costs are expensed as incurred. Advertising expenses totaled $121.5 million, $55.2 million and $88.5 million for the years ended December 31, 2024, 2023 and 2022, respectively.
Technology development
Technology development consists of employee compensation, including stock-based compensation and benefits, and expenses related to vendors engaged in product management, design, development and testing of the Company's websites and products. Technology development also includes allocated occupancy costs and related overhead costs based on headcount. Technology development costs are expensed as incurred, except for costs that are capitalized related to internal-use software development projects which are subsequently depreciated over the expected useful life of the developed software.
General and administrative
General and administrative includes employee compensation, including stock-based compensation and benefits for executive, finance, accounting, legal, business operations and other administrative personnel. In addition, general and administrative includes outside legal, tax and accounting services, non-income based taxes, insurance, charitable donations, and allocated occupancy costs and related overhead costs based on headcount.
Leases
The Company determines whether an arrangement is, or includes, a lease at its inception in accordance with ASC Topic 842, Leases (“ASC 842”). Operating lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. Right-of-Use (“RoU”) assets are equal to the operating lease liabilities with certain adjustments made for prepaid rent, lease incentives, or initial direct costs, as applicable. Operating lease RoU assets are presented under “Other assets” (Note 12) and Operating lease liabilities are presented under “Other Liabilities and Accrued Expenses” (Note 15). To determine the present value of lease payments, the Company uses an estimated incremental borrowing rate for leases of office spaces, as the rate implicit in the leases is not determinable, which is derived from information available at the lease commencement date. For certain leases that contain options to extend, the options are included in operating lease liabilities only if the Company is reasonably certain that the option will be exercised. Variable lease costs are recorded as expense when the events determining the amount of variable consideration have to be paid have occurred and are not included in the Company’s operating lease liabilities. The Company accounts for the lease and non-lease components as a single lease component for leases for real estate. Operating lease expense is recognized on a straight-line basis over the lease term.
Income from operating subleases where the Company is the sublessor is recognized on a straight-line basis over the lease term, which is presented under “Other Income” in the consolidated statements of operations and comprehensive income.
Operating lease RoU assets are evaluated for impairment at the asset group level whenever events or changes in circumstances indicate that the carrying amount of the asset group may not be recoverable. The carrying amount of an asset group, which includes the operating lease RoU asset is not recoverable if the carrying amount exceeds the sum of the undiscounted cash flows expected to result from the use of the asset group over the life of the primary asset in the asset group. The assessment is based on the carrying amount of the asset group, including the operating lease RoU asset and the related operating lease liability, at the date it is tested for recoverability and an impairment loss is measured and recognized as the amount by which the carrying amount of
the asset group exceeds its fair value. Any impairment loss is allocated to each asset in the asset group, including the operating RoU asset, on a pro-rata basis.
Accounting for stock-based compensation
The Company accounts for stock-based compensation in accordance with ASC Topic 718, Compensation — Stock Compensation (“ASC 718”). Stock options are mainly awarded to employees and members of the Company's board of directors and measured at fair value at each grant date. The Company calculates the fair value of share options on the date of grant using the Black-Scholes option-pricing model and the expense is recognized over the requisite service period for awards expected to vest using the straight-line method. The requisite service period for share options is generally four years. The Company recognizes forfeitures as they occur.
The Black-Scholes option-pricing model requires the Company to make a number of assumptions, including the value of the Company's common stock, expected volatility, expected term, risk-free interest rate and expected dividends. The Company evaluates the assumptions used to value option awards upon each grant of stock options. The expected option term was calculated based on the simplified method, which uses the midpoint between the vesting date and the contractual term, in accordance with ASC 718. The risk-free interest rate is based on observed interest rates appropriate for the term of the Company’s stock options. The dividend yield assumption is based on the Company’s history. The Company has not paid dividends and has no foreseeable plans to pay dividends. For restricted stock awards, the Company utilizes the fair value of the Company’s common stock on the date of grant to establish the fair value of the award.

Nonemployee stock-based compensation transactions in which the Company receives goods or services as consideration for its own equity instruments are accounted for as stock-based compensation transactions. The Company establishes and measures the fair value of these equity instruments at grant date, and is not remeasured. The fair value of a nonemployee award is estimated using the Black-Scholes option pricing model, which uses various inputs including the fair value of the Company’s common stock at grant date, contractual term, estimated volatility, risk-free interest rate and expected dividend yields of the common stock. The Company recognizes compensation expense over the vesting period subject to certain vesting events and thresholds, for each of the installment for a period of five years. The Company does not apply forfeiture for these awards given the nature of the vesting events and thresholds under the agreements (Notes 16 and 17).

Foreign currency
Financial statement accounts expressed in foreign currencies are translated into U.S. dollars. Functional currency assets and liabilities are translated into U.S. dollars generally using rates of exchange prevailing at the balance sheet date of each respective subsidiaries, and the related translation adjustments are recorded as a separate component of accumulated other comprehensive income, net of any related taxes.

Income taxes
The Company accounts for income taxes in accordance with the liability method whereby deferred tax assets and liability account balances are determined based on the differences between financial reporting and the tax basis for assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance, if necessary, to reduce deferred tax assets to the amounts that are more-likely-than-not to be realized. The Company assessed the positive and negative evidence of the realizability of the deferred tax assets amounts and determined that a valuation allowance was required. Accordingly, the Company provided a full valuation allowance against its deferred tax assets as of December 31, 2024 and 2023.
ASC Topic 740, Income Taxes, ("ASC 740") clarifies the accounting for uncertainties in income taxes by establishing minimum standards for the recognition and measurement of tax positions taken or expected to be taken in a tax return. Under the requirements of ASC 740, the Company reviews all of its tax positions and makes a determination as to whether its position is more-likely-than-not to be sustained upon examination by regulatory authorities. If a tax position meets the more-likely-than-not standard, then the related tax benefit is measured based on a cumulative probability analysis of the amount that is more-likely-than-not to be realized upon ultimate settlement or disposition of the underlying issue.
The Company classifies all interest and penalties related to uncertain tax positions as income tax expense.
Net loss per share
Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net loss attributable to common stockholders is computed by adjusting net loss attributable to common stockholders to reallocate undistributed earnings based on the potential impact of dilutive securities. Diluted net loss per share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period, including potential dilutive common shares. For purpose of this calculation, outstanding stock options and assumed warrants to purchase common shares of the Company are considered potential dilutive common shares.
In periods in which the Company reports a net loss attributable to common stockholders, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for the years ended December 31, 2024, 2023 and 2022.

Business Combination, Asset Acquisition, and Joint Venture Formation [Abstract]  
Acquisition of Metromile Acquisition of Metromile
On July 28, 2022 (the "Acquisition Date"), the Company completed its acquisition of Metromile, Inc. (“Metromile"), a leading digital insurance platform in the United States that offers real-time, personalized car insurance policies by the mile (the "Metromile Acquisition"). The Company acquired 100% of Metromile's equity through an all-stock transaction based upon the exchange ratio of 0.05263 shares of Lemonade for each outstanding share of Metromile. As a result of the acquisition, Metromile stockholders received 6,901,934 shares of Lemonade's common stock, with minimal cash paid in lieu of fractional shares. In addition, upon closing of the Metromile Acquisition, the Company assumed all outstanding and unexercised options, and outstanding restricted stock units (collectively referred to as "replacement awards") as of the Acquisition Date, which were converted into corresponding awards using the same exchange ratio of 0.05263 and with substantially identical terms and conditions prior to the close of the Metromile Acquisition.

Fair value of consideration transferred for the Metromile Acquisition is as follows ($ in millions):

Metromile issued and outstanding stock exchanged for Lemonade common stock (1)
$136.9 
Contingent consideration (2)
— 
Metromile vested awards exchanged for Lemonade awards (3)
0.8 
Total Purchase Consideration$137.7 
(1)    The fair value of 6,901,934 shares issued and exchanged for Lemonade common stock was determined based on the closing price at acquisition date of $19.84, and includes a minimal amount of cash paid in lieu of fractional shares.
(2)    Contingent consideration represents Metromile's contingently issuable shares that are convertible into Lemonade common stock in accordance with the exchange ratio as set forth in the merger agreement. In accordance with ASC 805-30-25-5, contingent consideration shall be recognized and measured at fair value as of the Acquisition Date. Given that the contingencies are not probable of being met within the contingency period, no fair value was assessed for these Metromile shares.
(3)    Fair value of replacement awards related to services rendered prior to the acquisition are included as part of purchase consideration. The unvested portion of fair value attributable to these replacement awards of $4.3 million comprised of $0.1 million for assumed options and $4.2 million for assumed restricted stock units ("RSUs"), and associated with future service will be recognized as expense over the future service period.
This Metromile Acquisition increased the Company's geographic footprint as a tech-enabled insurance provider and is expected to accelerate growth of the Lemonade car product, including other product offerings.
The Metromile Acquisition was accounted for as a business combination using the acquisition method of accounting in accordance with ASC 805, Business Combinations (“ASC 805”). The purchase price was allocated to assets acquired and liabilities assumed based on the estimated fair values at the Acquisition Date. The excess of the purchase price over the fair value of the net assets acquired was allocated to goodwill, and will not be deductible for tax purposes. Goodwill from this business combination is primarily attributable to synergies from future expected economic benefits, enhanced revenue growth from expanded capabilities and geographic presence, including cost savings from streamlined operations and enhanced operational efficiencies.
The following table presents the allocation of purchase consideration recorded on the consolidated balance sheet as of the Acquisition Date ($ in millions):

The amounts allocated to intangible assets were as follows ($ in millions):

Fair ValueWeighted-Average Useful Life
Technology$28.0

Total$35.5 

The Company also performed a quantitative goodwill impairment assessment during the fourth quarter of 2023 and 2024, primarily using projections of discounted cash flows to estimate the fair value of the reporting unit. The estimated fair value exceeded the carrying value of the reporting unit and concluded that goodwill was not impaired as of and for the years ended December 31, 2024 and December 31, 2023.
The results of operations for Metromile of $35.0 million of revenue and $36.4 million of net loss from the Acquisition Date to year ended December 31, 2022, have been included within the accompanying consolidated statements of operations and comprehensive loss.

The Company incurred transaction and integration costs of approximately $8.4 million for the year ended December 31, 2022. These expenses were included in “General and administrative expenses” within the Company’s consolidated statements of operations and comprehensive loss for the year ended December 31, 2022.
The unaudited supplemental pro forma combined financial information presents the Company’s results of operations for the year ended December 31, 2022 as if the Metromile Acquisition had occurred on January 1, 2022. The pro forma financial information is not necessarily indicative of the Company’s operating results that may have actually occurred had the Metromile Acquisition been completed on January 1, 2022. The unaudited pro forma financial information does not give effect to any anticipated cost savings, operating efficiencies or other synergies that may be associated with the acquisition, or any estimated costs that have been or will be incurred by the Company to integrate the assets and operations of Metromile. Unaudited pro forma total revenue and net loss amounted to $309.3 million and $383.0 million for the year ended December 31, 2022, respectively. The unaudited pro forma financial information reflects pro forma adjustments to present the combined pro forma results of operations as if the acquisition had occurred on January 1, 2022 to give effect to certain events the Company believes to be directly attributable to the acquisition. These pro forma adjustments primarily include:

a net decrease in amortization expense of $2.0 million that would have been recognized due to acquired intangible assets;
an increase of $10.0 million for acquisition-related transaction costs;
a decrease in operating revenues of $4.9 million due to the elimination of deferred revenues and assigned no value at the Acquisition Date;
a decrease to amortization expense of $1.3 million due to the elimination of unamortized deferred acquisition costs;
an increase to income of $0.6 million due to the adjustment of the loss and loss adjustment expense reserves at fair value; and
an increase in income of $2.0 million due to the depreciation of RoU assets and lease expense upon adoption of ASC 842.

Investments in fixed maturities with gross unrealized losses for twelve months or more was $0.5 million and $4.9 million for the years ended December 31, 2024 and 2023, respectively. The Company determined that unrealized losses on investment in fixed maturities were primarily due to the interest rate environment, and not credit risk related to the issuers of these securities. The Company does not intend to sell these investments in fixed maturities, and it is not more likely than not that that the Company will be required to sell these investments in fixed maturities before the recovery of the amortized cost basis. No allowance for credit losses related to any of these securities was recorded for the years ended December 31, 2024 and 2023.

The fair value of all our different classes of Level 2 fixed maturities and short-term investments are estimated by using quoted prices from a third-party valuation service provider to gather, analyze and interpret market information and derive fair values based upon relevant methodologies and assumptions for individual instruments.
There were no transfers between Level 1, Level 2, or Level 3 during the year ended December 31, 2024. There were no transfers between Level 1, Level 2 or Level 3 during the year ended December 31, 2023, other than the public and private warrants previously reported as Level 3 as discussed below.
Warrant liability
As part of the Metromile Acquisition as discussed in Note 5, public and private warrants were assumed from Metromile. These warrants do not meet the criteria for equity treatment and are recorded as a liability and presented under “Other liabilities and accrued expenses” on the consolidated balance sheets. These warrants are measured at fair value on a recurring basis at the end of each reporting period, with changes in fair value recognized and presented under “General and administrative expenses” in the consolidated statement of operations and comprehensive loss.
The public warrants liability is classified as Level 1 for fair value hierarchy disclosure purposes due to the use of an observable market quote in an active market, following the listing of the public warrants on New York Stock Exchange American in March 2023. The Company also reclassified the private warrants liability from Level 3 to Level 2, as the Company utilizes the observable prices of the public warrants in deriving the value of the private placement warrants.

Reinsurance

Dec. 31, 2024
Insurance [Abstract]  
Reinsurance Reinsurance
In the ordinary course of business, the Company cedes losses and LAE to other reinsurance companies. These arrangements reduce the net loss potentially arising from large or catastrophic risks. Certain of these arrangements consist of excess of loss and catastrophe contracts, which protect against losses exceeding stipulated amounts. The ceding of risk through reinsurance does not relieve the Company from its obligations to policyholders. The Company remains liable with respect to losses and LAE ceded in the event that any reinsurer does not meet obligations assumed under the reinsurance agreements. The Company does not have any significant unsecured aggregate recoverable for losses, paid and unpaid including IBNR, loss adjustment expenses, and unearned premium with any individual reinsurer.

The Company maintains proportional reinsurance contracts which cover all of the Company's products and geographies, and transferred, or “ceded,” a specified percentage of the premium to reinsurers ("Proportional Reinsurance Contracts"). The Company also opted to manage the remaining percentage of the business with alternative forms of reinsurance through non-proportional reinsurance contracts ("Non-Proportional Reinsurance Contracts").

Whole Account Quota Share Reinsurance Contracts

The Company agreed to the terms of a reinsurance program effective July 1, 2023 through June 30, 2024 which included Whole Account Quota Share Reinsurance Contracts by and among the Company, Lemonade Insurance Company ("LIC"), Metromile Insurance Company ("MIC") and Lemonade Insurance N.V. ("LINV"), and each of Hannover Ruck SE, MAPFRE Re, and Swiss Reinsurance America Corporation (collectively referred to as “Reinsurers”) ("Reinsurance Program"). Under the Reinsurance Program, which covers all products and geographies, the Company transfers, or "cedes," a share of premium to the Reinsurers. In exchange, these Reinsurers pay the Company a ceding commission on all premiums ceded to the Reinsurers, in addition to funding the corresponding claims, subject to certain limitations, including but not limited to, the exclusion of hurricane losses, and a limit of $5,000,000 per occurrence for non-hurricane catastrophe losses. The overall share of proportional reinsurance under the Reinsurance Program is approximately 55% of premium. The Per Risk Cap across the contracts is $750,000. Additionally, the contracts are subject to loss ratio caps and variable ceding commission levels, which align the Company's interests with those of its Reinsurers, and is settled primarily on a funds-withheld basis. The Reinsurance Program was renewed effective July 1, 2024 and will expire on June 30, 2025, with similar terms to the contracts that expired on June 30, 2024, except for the limit per occurrence for non-hurricane catastrophe losses which increased to $10,000,000.

MIC entered into a Quota Share reinsurance agreement effective January 1, 2022 and expired on June 30, 2023. Under the terms of the agreement, the Company ceded 30% of premiums and losses to reinsurers.
Property Per Risk Excess of Loss and Auto Facultative PPR Reinsurance Contracts

LIC and LINV entered into a Property Per Risk Excess of Loss Reinsurance Contract with a panel of reinsurance companies (the "PPR Contract"), and LIC entered into an Automatic Facultative Property Per Risk Excess of Loss Reinsurance Contract with Arch Re (the "Automatic Facultative PPR Contract"), each effective from July 1, 2023 until June 30, 2024. Under the PPR Contract, claims in excess of $750,000 are 100% ceded up to a maximum recovery of $2,250,000, subject to certain limitations. The PPR Contract was renewed with LIC and MIC at similar terms effective July 1, 2024 and will expire on June 30, 2025. The Automatic Facultative PPR Contract, in which claims in excess of $3,000,000 are 100% ceded with a potential recovery of at least $10,000,000, subject to certain limitations, expired on June 30, 2024, and was not renewed.

Excess of Loss Reinsurance Contract

The Company entered into an Excess of Loss ("XOL") Reinsurance Contract through a captive in Bermuda in which the Company has variable interest, primarily to cover catastrophe risk over the initial $50,000,000 limit for each loss occurrence, and further subject to a limit of $80,000,000 for each loss occurrence and in aggregate, primarily on property and auto business underwritten by LIC. This XOL reinsurance contract became effective July 1, 2023 and expired on June 30, 2024. The Company renewed the XOL reinsurance contract, effective July 1, 2024 through June 30, 2025 at similar terms and was expanded to include risks written by MIC.

The Company entered into a reinsurance program to protect against catastrophe risk in the U.S. that exceed $80,000,000 in losses effective July 1, 2022 which expired on June 30, 2023.

Captive

The Company is also exposed to some risks from MIC ceded through the Quota Share ("QS") Reinsurance Contract which is retained in an offshore captive subsidiary, Lemonade Re SPC. This QS reinsurance contract became effective July 1, 2023 and shall remain in force for an indefinite period until terminated by either party.

Through the offshore captives, the Company is exposed to the risk of natural catastrophe events and other covered risks under the reinsurance contracts from policies underwritten by LIC and MIC.

Reinsurance recoverable

Amounts recoverable from reinsurers are recognized in a manner consistent with the claims liabilities associated with the reinsurance placement and presented on the balance sheet as reinsurance recoverable. Such balance as of December 31, 2024 and 2023 are presented in the table below ($ in millions).

Reinsurance recoverable on paid losses$20.9 $18.2 
Ceded unpaid loss and LAE149.5 120.2 
Total reinsurance recoverable$170.4 $138.4 

To reduce credit exposure to reinsurance recoverable balances, the Company obtains letters of credit from certain reinsurers that are not authorized as reinsurers under U.S. state insurance regulations. In addition, under the terms of its reinsurance contracts, the Company may retain funds due to reinsurers as security for those recoverable balances. The Company has the following unsecured reinsurance recoverable balances from reinsurers at December 31, 2024 and 2023 with a majority of the reinsurers having A.M.

(1) Reinsurance recoverable in this table includes only ceded unpaid loss and LAE.
Unpaid loss and LAE includes anticipated salvage and subrogation recoverable.

Considerable variability is inherent in the estimate of the reserve for losses and LAE. Although management believes the liability recorded for losses and LAE is adequate, the variability inherent in this estimate could result in changes to the ultimate liability, which may be material to stockholders' equity. Additional variability exists due to accident year allocations of ceded amounts in accordance with reinsurance agreements, which is not expected to result in any changes to the ultimate liability. The Company had favorable development on net loss and LAE reserves of $10.0 million and $5.8 million as of December 31, 2024 and December 31, 2023, respectively. No additional premium or returned premium have been accrued as a result of prior year effects.
For the year ended December 31, 2024, current accident year incurred loss and LAE included $3.5 million from Hurricane Helene and $4.0 million from Hurricane Beryl. The net incurred loss and LAE from Hurricane Helene and Hurricane Beryl as of December 31, 2024 represents the Company's best estimates based upon available information.

For the year ended December 31, 2023, current accident year incurred loss and LAE included $10.4 million of net incurred loss and LAE from winter storm Elliott and $4.2 million from the hail storm that impacted customers in Texas. The net incurred loss and LAE from winter storm Elliott and hail storm that impacted customers in Texas as of December 31, 2023 represents the Company’s best estimates based upon available information.

The Company compiles and aggregates its claims data by grouping the claims according to the year in which the claim occurred (Accident Year) when analyzing claim payment and emergence patterns and trends over time. For the purpose of defining claims frequency, the number of reported claims is by loss occurrence and includes claims that do not result in a liability or payment associated with these claims.
The following is information about incurred and paid loss development as of December 31, 2024, net of reinsurance, as well as cumulative claim frequency and the total of IBNR liabilities included within the net incurred loss amounts. The Company separates home and renters claim experience from its pet claim experience when analyzing incurred and paid loss and allocated loss adjustment expenses, as there are distinct differences in the development and claim count emergence patterns. The information about incurred and paid claims development for the years ended prior to December 31, 2024 is presented as unaudited supplementary information.

Statutory Financial Information
U.S. state insurance laws and regulations prescribe accounting practices for determining statutory net income and capital and surplus for insurance companies. In addition, state regulators may permit statutory accounting practices that differ from prescribed practices. Statutory accounting practices ("SAP") prescribed or permitted by regulatory authorities for statements of the Company's insurance subsidiaries are (a) policy acquisition costs are expensed as incurred under SAP, whereas they are deferred and amortized under GAAP, (b) certain assets are not admitted for purposes of determining surplus under SAP, (c) investments in fixed income securities are carried at amortized cost under SAP, whereas such securities are carried at fair value under GAAP, and (d) the criteria for recognizing net deferred tax assets ("DTAs") and the methodologies used to determine such amounts are different under SAP and GAAP.
Risk-based capital (“RBC”) requirements promulgated by the National Association of Insurance Commissioners require property/casualty insurers to maintain minimum capitalization levels determined based on formulas incorporating various business risks of the insurance subsidiaries.
LIC’s statutory capital and surplus amounted to $195.1 million and $135.3 million as of December 31, 2024 and 2023, respectively. LIC’s capital and surplus exceeded its authorized control level RBC of $33.8 million and $32.5 million as of December 31, 2024 and 2023, respectively.

MIC’s statutory capital and surplus amounted to $25.2 million and $30.0 million as of December 31, 2024 and 2023. MIC’s capital and surplus exceeded its authorized control level RBC of $4.8 million and $6.3 million as of December 31, 2024 and 2023, respectively.

Statutory Dividend Restriction

The payment of dividends by LIC is restricted by state insurance regulations. Under New York insurance law, LIC may pay cash dividends only out of its statutory earned surplus. Generally, the maximum amount of dividends that LIC may pay without regulatory approval in any twelve-month period is the lesser of adjusted net investment income or 10% of statutory policyholders' surplus as of the end of the most recently reported quarter unless the NYS Department of Financial Services, upon prior application, approves a greater dividend distribution. Adjusted net investment income is defined for this purpose to include net investment income for the thirty-six months immediately preceding the declaration or distribution of the current dividend less any dividends declared or distributed during the period commencing thirty-six months prior to the declaration or distribution of the current dividend and ending twelve months prior thereto. As of December 31, 2024 and 2023, LIC was not eligible to make dividend payments.
The payment of dividends by MIC is restricted by the laws of the State of Delaware. The maximum amount that can be paid without prior notice or approval is the greater of 10% of policyholders’ surplus as of the preceding December 31, or net income not including realized capital gains for the twelve-month period ending the preceding December 31. Because the Company has an unassigned deficit at December 31, 2024 and 2023, MIC’s dividend policy is governed by Section 5005(B) of the Delaware insurance code whereby a domestic insurer may not declare or pay a dividend or other distribution from any source other than earned surplus without the commissioner’s prior approval. MIC paid no dividends to the Company in 2024 and 2023.

2020 Incentive Compensation Plan
On July 2, 2020, the Company’s board of directors adopted and the Company’s stockholders approved the 2020 Incentive Compensation Plan (the “2020 Plan”), which became effective immediately prior to the effectiveness of the registration statement for the Company’s IPO in 2020. The 2020 Plan provides for the issuance of incentive stock options, non-qualified stock options, stock awards, stock units, stock appreciation rights and other stock-based awards.

The number of shares initially reserved for issuance under the 2020 Plan is 5,503,678 shares, is inclusive of available shares previously reserved for issuance under the 2015 Incentive Share Option Plan, as amended and restated on September 4, 2019 (the “2015 Plan”). In addition, the number of shares reserved for issuance under the 2020 Plan is subject to increase for awards previously issued under the 2015 Plan which are forfeited or lapse unexercised. Annually, on the first day of each calendar year beginning on January 1, 2021 and ending on and including January 1, 2030, the reserve will be increased by an amount equal to the lesser of (A) 5% of the shares outstanding (on an as-converted basis) on the last day of the immediately preceding fiscal year and (B) such smaller number of shares as determined by the Company’s board of directors, provided that no more than 3,650,000 shares may be issued upon the exercise of incentive stock options. As of December 31, 2024, there were 4,679,331 shares of common stock available for future grants.

2020 Employee Stock Purchase Plan

On July 2, 2020, the Company's board of directors adopted and the Company's stockholders approved the 2020 Employee Stock Purchase Plan (the "2020 ESPP"), which became effective immediately prior to the effectiveness of the registration statement for the Company's IPO in 2020. The total shares of common stock initially reserved for issuance under the 2020 ESPP is limited to 1,000,000 shares. In addition, the number of shares available for issuance under the 2020 ESPP will be annually increased on January 1 of each calendar year beginning on January 1, 2021 and ending on and including January 1, 2030, by an amount equal to the lesser of (A) 1,000,000 Shares, (B) 1% of the shares outstanding on the final day of the immediately preceding calendar year and (C) such smaller number of shares as is determined by the board of directors. The board of directors or a committee of the board of directors will administer and will have authority to interpret the terms of the 2020 ESPP and determine eligibility of participants. There were no shares issued under the 2020 ESPP as of December 31, 2024.

2015 Incentive Share Option Plan

In July 2015, the Company adopted the 2015 Incentive Share Option Plan (“2015 Plan”). The 2015 Plan has been amended and restated from time to time to increase the number of shares reserved for grant and to enable the grant of options to employees of the Company's subsidiaries. Under the 2015 Plan, options to purchase common stock of the Company may be granted to employees, officers, directors and consultants of the Company. Each option granted can be exercised for one share of common stock of the Company. Options granted to employees generally vest over a period of no more than four years. The options expire ten years from the date of grant.
Pursuant to the 2015 Plan, the Company had reserved 7,312,590 shares of common stock for issuance. Effective immediately upon the approval of the 2020 Plan, the remaining shares of common stock available for future grant under the 2015 Plan were transferred to the 2020 Plan. As of December 31, 2024, there were no shares of common stock available for future grant under the 2015 Plan. Subsequent to the approval of the 2020 Plan, no additional grants were made under the 2015 Plan and any outstanding awards under the 2015 Plan will continue with their original terms.
Assumed Share Option Plans
As part of the Metromile Acquisition in 2022, the Company assumed the Metromile 2011 Incentive Stock Plan (“2011 Plan”) and Metromile 2021 Incentive Stock Plan (“2021 Plan”) (collectively referred to as “Assumed Plans”). The equity awards assumed of 404,207 were granted from the respective Assumed Plans and will be settled in the Company’s common stock (Note 5). The remaining unallocated shares reserved under both the 2011 and 2021 Plan were cancelled and no new awards will be granted under these Assumed Plans.

Share-pool increase in 2020 Incentive Compensation Plan and 2020 Employee Stock Purchase Plan

On January 1, 2025, the 2020 Plan share pool was increased by 3,636,043 shares, equal to 5% of the aggregate number of outstanding common stock as of December 31, 2024. There was no increase in the 2020 ESPP share pool as of January 1, 2025.

Options granted to employees and non-employees
The fair value of each option granted during the year ended December 31, 2024 and 2023 is estimated on the date of grant using the Black-Scholes model with the following assumptions:
December 31,
20242023
Weighted average expected term (years)5.86.0
Risk-free interest rate4.1%4.2%
Volatility77%74%
Expected dividend yield0%0%
Expected volatility is calculated based on implied volatility from market comparisons of certain publicly traded companies and other factors. The expected term of options granted is based on the simplified method, which uses the midpoint between the vesting date and the contractual term in accordance with ASC 718. The risk-free interest rate is based on observed interest rates appropriate for the term of the Company's stock options. The dividend yield assumption is based on the Company's historical and expected future dividend payouts and may be subject to substantial change in the future.

Deferred taxes
Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes. The Company's deferred tax assets are comprised of operating loss carryforwards and other temporary differences.

The components of the net deferred tax assets are as follows ($ in millions):

As of December 31, 2024 and 2023 respectively, $9.7 million and $13.3 million of unrealized tax benefits, if recognized, would decrease the effective tax rate.

The activity in unrecognized tax benefits for the year ended December 31, 2024 is related to establishing additional reserves for its foreign jurisdictions, and offset by a change in estimate resulting from updated benchmarking analyses in the current year.

The Company recognizes interest and penalties related to unrecognized tax benefits on the income tax expense line in the accompanying consolidated statement of operations and comprehensive income. The Company accrued and recognized interest expense related to uncertain tax positions of $0.5 million and $0.4 million for the years ended December 31, 2024 and 2023. There are no penalties related to the uncertain tax positions for the years ended December 31, 2024 and 2023.

The Company believes it is reasonably possible that our unrecognized tax benefits could increase or decrease within the next 12 months.

The Company selected to apply the "period cost method" to account for the Global Intangible Low-Taxed Income, and treated it as a current-period expense in its taxable income. Gross inclusion amounted to $4.1 million for the year ended December 31, 2023 and there was none for the years ended December 31, 2024 and 2022.
Net operating loss carryforward
As of December 31, 2024, the Company has federal losses for tax purposes of $296.2 million, which can be offset against future taxable income. Of this federal loss carryforward, $10.5 million in losses will begin to expire in 2035 and $285.7 million in losses can be carried forward indefinitely. As of December 31, 2024, the Company has state and local losses for tax purposes of $35.3 million which will begin to expire in 2029.
The Company's income tax returns for 2021 through 2023 remain subject to examination by the U.S. tax authorities.

Inflation Reduction Act

The Inflation Reduction Act, which created a new corporate alternative minimum tax (CAMT) effective for calendar year taxpayers January 1, 2023, was enacted on August 16, 2022. Based upon projected adjusted financial statement income for 2024 and 2023, the reporting entity (or the controlled group of corporations of which the reporting entity is a member) has determined that average "adjusted financial statement income" is below the thresholds for the 2024 and 2023 tax year such that it does not expect to be required to perform the CAMT calculations, nor be liable for any CAMT.

382 Limitation

On March 12, 2018, the Company underwent a change of control under Section 382 of the Internal Revenue Code by the purchase of interest by additional investors. Accordingly, a portion of the Company’s deferred tax assets are subject to an annual limitation under Section 382. The annual deduction limitations apply to approximately $43.0 million of net operating losses. The Company is not expected to write off any deferred tax assets as a result of these limitations. The Company may experience ownership changes in the future as a result of subsequent shifts in our stock ownership.

Bermuda Corporate Income Tax Regime

On December 18, 2023, Bermuda enacted a 15% corporate income tax regime (the “Bermuda CIT”) that applies to Bermuda businesses that are part of multinational enterprise groups with annual revenue of €750 million or more and is effective for tax years beginning on or after January 1, 2025. The Company does not expect that this will impact income tax provision until the Company meets the required annual revenue threshold.

The Company's potentially dilutive securities, which include stock options, unvested RSUs and warrants for common stock, have been excluded from the computation of diluted net loss per share as the effect would be to anti-dilutive. Therefore, the weighted average number of common shares outstanding used to calculate both basic and diluted net loss per share attributable to common stockholders is the same. The Company excluded the following potential common shares, presented based on amounts outstanding at each period end, from the computation of diluted net loss per share attributable to common stockholders for the periods indicated because including them would have had an anti-dilutive effect.

The Company is occasionally a party to routine claims or litigation incidental to its business. The Company records accruals for loss contingencies with these legal matters when it is probable that a liability will be incurred, and the amount of loss can be reasonably estimated.

The Company has a potential liability claim exposure related to Metromile for which the Company has determined that a liability associated with this matter is probable and can be reasonably estimated, and therefore has recorded a liability for this matter in accordance with ASC 450. The Company will continue to monitor all legal issues and assess whether to accrue liability in accordance with ASC 450 based on new information and as further developments arise.

In November 2024, the Company extended the lease for two floors of its New York office through February 2029, with the lease for the remaining floors expiring in November 2025. The New York office lease extension includes a renewal option provision to further extend the lease term in which the Company is not currently reasonably certain to exercise. The Company accounted for the lease as a modification in which the modified lease classification remains to be an operating lease. The related RoU asset and lease liability were remeasured as a result of the lease modification for which the Company recorded an increase of $4.5 million in RoU asset and $4.3 million in lease liability.

Office lease agreements for Tempe, Arizona and Scottsdale, Arizona expired in October 2024 and November 2024, respectively, and were not renewed by the Company.

Sublease
New York
The Company subleased two floors of its New York office space beginning September 2023 through November 2025, which are classified as operating leases. As a result of the sublease, the Company evaluated RoU asset associated with the original lease for impairment, using the undiscounted cash flows from the sublease. There was no impairment charge recognized related to the New York office sublease as of December 31, 2023.

The Company also entered into a sublease agreement for a portion of its office space in New York which commenced in June 2024 through November 2025, which is classified as an operating lease. The Company recorded an impairment charge related to the sublease of $0.3 million which reduced the carrying value of RoU assets and the related furniture and equipment and leasehold improvements as of December 31, 2024.

The Company recognized sublease income from the above sublease agreements of $1.9 million and $0.4 million for the years ended December 31, 2024 and 2023, respectively.

San Francisco

The Company subleased its San Francisco office space beginning November 2023 through November 2026, and is classified as an operating lease. The Company recorded an impairment charge related to the sublease of $3.7 million which reduced the carrying value of RoU assets and the related leasehold improvements as of December 31, 2023.

The Company recognized sublease income of $1.1 million and $0.2 million for the years ended December 31, 2024 and 2023, respectively.

The impairment charge related to the sublease is presented under “General and administrative expenses” in the consolidated statements of operations and comprehensive income. The Company estimated the fair value of the RoU asset based on the net present value of the sublease rental income during the sublease term.

Sublease income is presented under “Commission and other income” in the consolidated statements of operations and comprehensive income.

Unpaid loss and LAE includes anticipated salvage and subrogation recoverable.

Considerable variability is inherent in the estimate of the reserve for losses and LAE. Although management believes the liability recorded for losses and LAE is adequate, the variability inherent in this estimate could result in changes to the ultimate liability, which may be material to stockholders' equity. Additional variability exists due to accident year allocations of ceded amounts in accordance with reinsurance agreements, which is not expected to result in any changes to the ultimate liability. The Company had favorable development on net loss and LAE reserves of $10.0 million and $5.8 million as of December 31, 2024 and December 31, 2023, respectively. No additional premium or returned premium have been accrued as a result of prior year effects.
For the year ended December 31, 2024, current accident year incurred loss and LAE included $3.5 million from Hurricane Helene and $4.0 million from Hurricane Beryl. The net incurred loss and LAE from Hurricane Helene and Hurricane Beryl as of December 31, 2024 represents the Company's best estimates based upon available information.

For the year ended December 31, 2023, current accident year incurred loss and LAE included $10.4 million of net incurred loss and LAE from winter storm Elliott and $4.2 million from the hail storm that impacted customers in Texas. The net incurred loss and LAE from winter storm Elliott and hail storm that impacted customers in Texas as of December 31, 2023 represents the Company’s best estimates based upon available information.

The Company compiles and aggregates its claims data by grouping the claims according to the year in which the claim occurred (Accident Year) when analyzing claim payment and emergence patterns and trends over time. For the purpose of defining claims frequency, the number of reported claims is by loss occurrence and includes claims that do not result in a liability or payment associated with these claims.
The following is information about incurred and paid loss development as of December 31, 2024, net of reinsurance, as well as cumulative claim frequency and the total of IBNR liabilities included within the net incurred loss amounts. The Company separates home and renters claim experience from its pet claim experience when analyzing incurred and paid loss and allocated loss adjustment expenses, as there are distinct differences in the development and claim count emergence patterns. The information about incurred and paid claims development for the years ended prior to December 31, 2024 is presented as unaudited supplementary information.

Statutory Financial Information
U.S. state insurance laws and regulations prescribe accounting practices for determining statutory net income and capital and surplus for insurance companies. In addition, state regulators may permit statutory accounting practices that differ from prescribed practices. Statutory accounting practices ("SAP") prescribed or permitted by regulatory authorities for statements of the Company's insurance subsidiaries are (a) policy acquisition costs are expensed as incurred under SAP, whereas they are deferred and amortized under GAAP, (b) certain assets are not admitted for purposes of determining surplus under SAP, (c) investments in fixed income securities are carried at amortized cost under SAP, whereas such securities are carried at fair value under GAAP, and (d) the criteria for recognizing net deferred tax assets ("DTAs") and the methodologies used to determine such amounts are different under SAP and GAAP.
Risk-based capital (“RBC”) requirements promulgated by the National Association of Insurance Commissioners require property/casualty insurers to maintain minimum capitalization levels determined based on formulas incorporating various business risks of the insurance subsidiaries.
LIC’s statutory capital and surplus amounted to $195.1 million and $135.3 million as of December 31, 2024 and 2023, respectively. LIC’s capital and surplus exceeded its authorized control level RBC of $33.8 million and $32.5 million as of December 31, 2024 and 2023, respectively.

MIC’s statutory capital and surplus amounted to $25.2 million and $30.0 million as of December 31, 2024 and 2023. MIC’s capital and surplus exceeded its authorized control level RBC of $4.8 million and $6.3 million as of December 31, 2024 and 2023, respectively.

Statutory Dividend Restriction

The payment of dividends by LIC is restricted by state insurance regulations. Under New York insurance law, LIC may pay cash dividends only out of its statutory earned surplus. Generally, the maximum amount of dividends that LIC may pay without regulatory approval in any twelve-month period is the lesser of adjusted net investment income or 10% of statutory policyholders' surplus as of the end of the most recently reported quarter unless the NYS Department of Financial Services, upon prior application, approves a greater dividend distribution. Adjusted net investment income is defined for this purpose to include net investment income for the thirty-six months immediately preceding the declaration or distribution of the current dividend less any dividends declared or distributed during the period commencing thirty-six months prior to the declaration or distribution of the current dividend and ending twelve months prior thereto. As of December 31, 2024 and 2023, LIC was not eligible to make dividend payments.
The payment of dividends by MIC is restricted by the laws of the State of Delaware. The maximum amount that can be paid without prior notice or approval is the greater of 10% of policyholders’ surplus as of the preceding December 31, or net income not including realized capital gains for the twelve-month period ending the preceding December 31. Because the Company has an unassigned deficit at December 31, 2024 and 2023, MIC’s dividend policy is governed by Section 5005(B) of the Delaware insurance code whereby a domestic insurer may not declare or pay a dividend or other distribution from any source other than earned surplus without the commissioner’s prior approval. MIC paid no dividends to the Company in 2024 and 2023.

Cybersecurity Risk Management Processes for Assessing, Identifying, and Managing Threats [Text Block]  
We have developed and implemented a cybersecurity risk management program intended to protect the confidentiality, integrity, and availability of our critical systems and information. Our cybersecurity risk management program includes a cybersecurity incident response plan, employee training, testing and assessments and a third party risk management process.

Our program is informed by best practice approaches relevant to the technologies we use, the environments in which our services are designed and deployed, our business needs, and relevant regulatory requirements. This does not imply that we meet any particular technical standards, specifications, or requirements, only that we use the various standards and frameworks as guides to help us identify, assess, and manage cybersecurity risks relevant to our business.

Our cybersecurity risk management program is integrated into our overall enterprise risk management program, and shares common approaches, reporting channels, and governance processes that apply the enterprise risk management program to other legal, compliance, strategic, operational, and financial risk areas.

Our cybersecurity risk management program includes:

Risk assessments designed to help identify material cybersecurity risks to our critical systems, information, products, services, and our broader enterprise IT environment;
A security team principally responsible for managing (1) our cybersecurity risk assessment processes, (2) our security controls, and (3) our response to cybersecurity incidents;
The use of external service providers, where appropriate, to assess, test or otherwise assist with aspects of our security controls;
Security tools deployed in the IT environment for protection against and monitoring of suspicious events;
Security awareness training of our employees, incident response personnel, and senior management;
A cybersecurity incident response plan that includes procedures for responding to cybersecurity incidents; and
A third-party risk management process for service providers, suppliers, and vendors who access our data and/or systems.

We have not identified known cybersecurity threats to date that could have materially affected or are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. We face certain ongoing risks from cybersecurity threats such as loss or theft of data, disruptive attacks from financially motivated bad actors, and third party supply chain issues that, if realized, are reasonably likely to materially affect us, including our operations, business strategy, results of operations, or financial condition. See “Risk Factors – Risks Relating to Our Business.”

Summary of Significant Accounting Policies (Policies)
12 Months Ended
Dec. 31, 2024
Accounting Policies [Abstract]  
Basis of presentation
The Company presents its financial statements on a consolidated basis including all of its wholly-owned subsidiaries and a variable interest entity for which the Company is deemed to be the primary beneficiary. All intercompany balances and transactions have been eliminated. All foreign currency amounts in the consolidated statements of operations and comprehensive loss have been translated using an average rate for the reporting period. All foreign currency balances in the consolidated balance sheets have been translated using the spot rate at the end of the year. All figures expressed, except share amounts are represented in U.S. dollars in millions.
Use of estimates
The preparation of the consolidated financial statements in conformity with U.S. Generally Accepted Accounting Principles ("GAAP") requires management to make estimates and assumptions that affect the amounts reported in the consolidated financial statements and accompanying notes. On an ongoing basis, the Company’s management evaluates estimates, including those related to contingent assets and liabilities as of the date of the consolidated financial statements as well as the reported amounts of revenue and expense during the reporting period. Such estimates are based on historical experience and on various other assumptions that are believed to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities. These estimates, judgments and assumptions can affect the reported amounts of assets and liabilities at the dates of the consolidated financial statements, and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates. All revisions to accounting estimates are recognized in the period in which the estimates are revised. Significant estimates reflected in the Company's consolidated financial statements include, but are not limited to, reserves for loss and loss adjustment expense, reinsurance recoverable on unpaid losses, intangible assets, uncertain tax position and valuation allowance on deferred tax assets.
Segment information
The Company's chief operating decision maker is the Chief Executive Officer. The chief operating decision maker manages the operations, allocate resources, and evaluate financial performance on a company-wide basis. The Company operates in one reporting segment within the United States, Europe, including the United Kingdom, providing insurance products to customers through various sales channels. See Note 24 for additional information.
Cash, cash equivalents and restricted cash
Cash and cash equivalents consist primarily of bank deposits and money market accounts with maturities of three months or less at the date of acquisition and are stated at cost, which approximates fair value. The Company's restricted cash primarily relates to insurance policy premiums collected by the Company that it holds in a segregated cash account for transmittal to the underwriting carrier, or settlement of insurance related claims. The Company also has restricted cash relating to security deposits for certain office leases. The carrying value of restricted cash approximates fair value.
Investments
Investments consist of fixed maturity securities and short-term investments. The Company considers all of its fixed maturity securities as available-for-sale and are carried at fair value. Fixed maturity securities consist of securities with an initial fixed maturity of more than one year. Unrealized gains and losses related to bonds are included in accumulated other comprehensive income as a separate component of stockholders' equity. The discount or premium on bonds is amortized using the effective yield method. Short-term investments, which may include commercial paper, certificates of deposit, and fixed maturity securities with an initial maturity of one year or less, are carried at amortized cost, which approximates fair value.
The fair value of bonds is principally derived from market price data for identical assets from exchange or dealer markets and from market observable inputs such as interest rates and yield curves that are observable at commonly quoted intervals. For certain bonds for which market prices are not readily available, if applicable, market values are principally estimated using values obtained from independent pricing services, broker quotes and internal estimates.
Interest income, as well as prepayment fees and the amortization of the related premium or discount, is reported in net investment income. Realized gains or losses on the sale of investments are determined on the basis of specific identification.
The Company continuously monitors the difference between cost and the estimated fair value of its investments. Each reporting period, securities with unrealized losses are reviewed to determine whether the decline in fair value requires the recognition of an allowance for credit losses. Factors considered in the review include (i) current market interest rates, (ii) general financial condition of the issuer, (iii) issuers industry and future business prospects, (iv) issuers past defaults in principal and interest payments, and (v) the payment structure of the investment and the issuers ability to make contractual payments on the investment.

The Company also considers whether it intends to sell the security, or if it is more likely than not that it will be required to sell the security before recovery of its amortized cost. When assessing whether it intends to sell a fixed-maturity security or if it is likely to be required to sell a fixed-maturity security before recovery of its amortized cost, the Company evaluates certain relevant facts and circumstances which may include, but not limited to, business prospects, credit ratings and available information from asset managers and rating agencies for individual securities.
For fixed-maturity securities where a decline in fair value is below the amortized cost basis and the Company intends to sell the security, or it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost, a credit-loss charge is recognized in net income based on the fair value of the security at the time of assessment. For fixed-maturity securities that the Company has the intent and ability to hold, the Company compares the estimated present value of the cash flows expected to be collected to the amortized cost of the security. The extent to which the estimated present value of the cash flows expected to be collected is less than the amortized cost of the security and represents the credit-related portion of the impairment, such is recognized in net income through an allowance for credit losses. Any remaining decline in fair value represents the noncredit portion of the impairment, which is recognized in other comprehensive income.

Accrued interest receivable is recorded as a component of accrued investment income on its consolidated balance sheet which is presented separately from available-for-sale securities. The Company does not measure an allowance for credit losses on accrued interest receivable and would instead write off accrued interest receivable at the time an issuer defaults or is expected to default on payments.
Fair value of financial instruments
Fair value is defined as the price that would be received upon the sale of an asset or paid to transfer a liability in an orderly transaction between willing, able and knowledgeable market participants at the measurement date. Fair value measurements are not adjusted for transaction costs. In addition, a three-tiered hierarchy for inputs is used in management's determination of fair value of financial instruments that emphasizes the use of observable inputs over the use of unobservable inputs by requiring that the observable inputs be used when available. Observable inputs are market participant assumptions based on market data obtained from sources independent of the Company. Unobservable inputs are the reporting entity's own assumptions about market participant assumptions based on the best information available under the circumstances. In assessing the appropriateness of using observable inputs in making its fair value determinations, the Company considers whether the market for a particular security is "active" or not based on all the relevant facts and circumstances.
To determine the fair value of its investments, the Company utilizes third-party valuation service providers to gather, analyze and interpret market information and derive fair values based upon relevant methodologies and assumptions for individual instruments.
Valuation service providers typically obtain data about market transactions and other key valuation model inputs from multiple sources and, through the use of widely accepted valuation models, provide a single fair value measurement for individual securities for which a fair value has been requested under the terms of service agreements. The inputs used by the valuation service providers include, but are not limited to, market prices from recently completed transactions and transactions of comparable securities, interest rate yield curves, credit spreads, currency rates and other market observable information, as applicable. The valuation models consider, among other things, market observable information as of the measurement date as well as the specific attributes of the security being valued including its term, interest rate, credit rating, industry sector and, when applicable, collateral quality
and other issue or issuer specific information. When market transactions or other market observable data is limited, the extent to which judgment is applied in determining fair value is greatly increased.
As a basis for considering such assumptions, a three-tier value hierarchy is used in management's determination of fair value based on the reliability and observability of inputs as follows:
Level 1 — Valuations are based on unadjusted quoted prices in active markets that the Company has the ability to access for identical, unrestricted assets and do not involve any meaningful degree of judgment. An active market is defined as a market where transactions for the financial instrument occur with sufficient frequency and volume to provide pricing information on an ongoing basis;
Level 2 — Valuations are based on direct and indirect observable inputs other than quoted market prices included in Level 1. Level 2 inputs include quoted prices for similar assets in active markets and inputs other than quoted prices that are observable for the asset, such as the terms of the security and market-based inputs;
Level 3 — Valuations are based on techniques that use significant inputs that are unobservable. The valuation of Level 3 assets and liabilities requires the greatest degree of judgment. These measurements may be made under circumstances in which there is little, if any, market activity for the asset or liability. The Company's assessment of the significance of a particular input to the fair value measurement in its entirety requires judgment. In making the assessment, the Company considers factors specific to the asset. In certain cases, the inputs used to measure fair value may fall into different levels of the fair value hierarchy. In such cases, the level in the fair value hierarchy within which the fair value measurement is classified is determined based on the lowest level input that is significant to the fair value measurement in its entirety.
The Company's fair value measurements include investments, intangible assets, warrants liability and stock options.
Concentrations of credit risk
Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, fixed maturity securities and reinsurance recoverables. Cash and cash equivalents are held with financial institutions of high credit quality, and fixed maturity securities primarily on U.S. government, U.S. government agencies, and high credit quality issuers of debt securities. Cash and cash equivalent balances may exceed the amount of insurance provided on such balances. The Company evaluates the financial condition of its reinsurers, and reinsures its business primarily with highly rated reinsurers, and may retain funds due to reinsurers or require letters of credit as security for those recoverable balances (Note 8).
Premium receivable Premium receivable is reported net of an allowance for estimated uncollectible premium amounts. Premiums receivable are short-term in nature and due within a year. Allowance is based upon the ongoing review of amounts outstanding, length of collection periods, the creditworthiness of the insured and other relevant factors. Amounts deemed to be uncollectible are written off against the allowance.
Reinsurance
Reinsurance is used to mitigate the exposure to losses, manage capacity and protect capital resources. Reinsuring loss exposures does not relieve the Company from its obligations to policyholders. Reinsurance recoverable, including amounts related to incurred but not reported claims (“IBNR”) and prepaid reinsurance premium, is reported as an asset. To minimize exposure to losses related to a reinsurer's inability to pay, the financial condition of such reinsurer is evaluated initially upon placement of the reinsurance and periodically thereafter. In addition to considering the financial condition of a reinsurer, the collectability of the reinsurance recoverable is evaluated based upon a number of other factors. Such factors include the amounts outstanding, length of collection periods, disputes, any collateral or letters of credit held and other relevant factors. To the extent that an allowance for uncollectible reinsurance recoverable is established, amounts deemed to be uncollectible would be written off against the allowance for estimated uncollectible reinsurance recoverable. The Company has no historical experience on credit losses from reinsurance recoverables and has not recorded any allowance for uncollectible reinsurance recoverable as of December 31, 2024 and December 31, 2023.
Amounts recoverable from reinsurers are estimated in a manner consistent with the liability associated with the reinsured business and consistent with the terms of the underlying contract.
Ceded premium written is recorded in accordance with the applicable terms of the reinsurance contracts and ceded premium earned is charged against revenue over the period of the reinsurance contracts. Ceded losses incurred reduce net loss and loss adjustment expense incurred over the applicable periods of the reinsurance contracts with third-party reinsurers.
The ceding of insurance does not legally discharge the Company from its primary liability for the full amount of the policy coverage, and therefore the Company will be required to pay the loss and bear collection risk if the reinsurer fails to meet its obligations under the reinsurance agreement. To minimize exposure to significant losses from reinsurance insolvencies, the Company evaluates the financial condition of its reinsurers and monitors concentrations of credit risk.
Prepaid reinsurance premiums represents the unearned portion of premiums ceded to reinsurers. Funds held under reinsurance treaties represent amounts retained by the Company on behalf of the reinsurer based on terms of the reinsurance agreements.
Deferred acquisition costs Direct acquisition costs, which primarily consist of commissions and premium taxes, related to each policy the Company successfully writes are deferred and amortized to expense in proportion to the premium earned, generally over a period of one year. Deferred acquisition costs are reviewed at least annually to determine their recoverability from future income. If any such costs are determined not to be recoverable they are charged to expense. Anticipated net loss and loss adjustment expense and estimated remaining costs of servicing contracts are considered when evaluating recoverability of deferred acquisition costs.
Property and equipment, net Property and equipment are stated at cost, net of accumulated depreciation.
Capitalized internal use software
The Company defers certain costs related to the development of internal use software, which are incurred during the application development stage, and amortizes them over the software's estimated useful life. The amounts capitalized include employee payroll and payroll-related costs directly associated with the development activities. The Company's policy is to amortize capitalized costs using the straight-line method over the estimated useful life, which is currently two years, beginning when the software is substantially complete and ready for its intended use. Costs incurred in the preliminary and post-implementation stages of the Company's products are expensed as incurred.
Intangible assets
Intangible assets are recorded at their acquisition date fair values which involves the use of valuation methodologies appropriate for determining the market value of each asset. These valuation methodologies use various assumptions that are inherently subjective. Identifiable intangible assets consist of value of business acquired and technology, which are subject to amortization, and insurance licenses and trademark associated with the Company’s name acquired in 2019, which are not subject to amortization.
Indefinite-lived intangible assets are tested for impairment at least annually, or more frequently if events or such as a change in business circumstances that indicates the carrying value of the assets may not be recoverable. The annual impairment test for indefinite-lived intangible assets may be completed through a qualitative assessment to determine if the fair value of the indefinite-lived intangible assets is more likely than not greater than the carrying amount. The Company may elect to bypass the qualitative assessment, or if a qualitative assessment indicates it is more likely than not that the estimated carrying value exceeds the fair value, the Company will test for impairment using a quantitative process. If the Company determines that impairment of its intangible assets may exist, the amount of impairment loss is measured as the excess of carrying value over fair value. The estimates in the determination of the fair value of indefinite-lived intangible assets include the anticipated future revenues of the Company and the resulting cash flows. There were no circumstances that indicate that the carrying amount of intangible assets deemed to have an indefinite useful life may not be recoverable for the years ended December 31, 2024 and 2023.

Intangible assets subject to amortization are amortized over the estimated useful life and reviewed for impairment when indicators exist.
Goodwill
Goodwill is the excess of purchase price over the fair value of net assets acquired. Goodwill is not amortized, but instead is reviewed for impairment at the reporting unit level on an annual basis, during the fourth quarter, or more frequently if indicators of impairment exist. The annual impairment test for goodwill is initially completed through a qualitative assessment to determine if it is more likely than not that the fair value of a reporting unit is less than its carrying value. If facts and circumstances determine that it is not more likely than not that a reporting unit fair value is less than its carrying amount, then additional testing of goodwill is not required. However, if the Company determines that it is more likely than not that the fair value of a reporting unit is less than the carrying value, then the Company will perform a quantitative analysis. The quantitative analysis compares the estimated fair value of a reporting unit to its carrying value, including goodwill. If the fair value exceeds the carrying value, there is no impairment on recorded goodwill. However, if the carrying value exceeds the fair value of a reporting unit, an impairment loss will be recognized in the amount of the excess carrying value over fair value limited by the total amount of goodwill for the reporting unit. The Company elected to bypass the qualitative assessment allowed under the guidance and performed a quantitative goodwill impairment assessment during the fourth quarter of 2024, and estimated the fair value of the reporting unit using the income approach, based on the discounted cash flow valuation techniques, and the market valuation approach. Based on the quantitative analysis, the estimated fair value exceeded the carrying value of the reporting unit and concluded that there was no impairment of the recorded goodwill as of December 31, 2024.
Variable Interest
The Company accounts for its variable interest entity (“VIE”) in accordance with Accounting Standards Codification (“ASC”) Topic 810, Consolidation, which requires consolidation of VIEs by the primary beneficiary. A VIE is an entity where the investor lacks certain essential characteristics of a controlling financial interest, which may include a simple majority kick-out rights, or lacks sufficient funds to finance its own activities without financial support provided by other entities. The Company is deemed to have a controlling financial interest when it has both the ability to direct the activities that most significantly impact the economic performance of the VIE and the obligation to absorb losses or right to receive benefits from the VIE that could potentially be significant to the VIE. The Company consolidates the VIE in its consolidated financial statements when it is determined to be the primary beneficiary. The Company reassesses its determination of whether the Company is the primary beneficiary of a VIE, upon changes in facts and circumstances that could potentially alter the Company’s assessment.
The Company in 2023 established a captive cell facility at a Bermuda transformer vehicle that is authorized to write and purchase insurance and reinsurance to retain most of the Company’s windstorm exposure (Note 8). Through the Company’s participation interest in this arrangement which is considered a VIE, the Company determined that it is the primary beneficiary of the VIE since it has the power to direct and exercise control over the significant activities and has the obligation to absorb losses or the right to receive residual returns of the VIE. As a result, the Company included the VIE in the consolidated financial statements.
Unpaid loss and loss adjustment expense
The reserves for loss and loss adjustment expense represent management's best estimate of the ultimate cost of all reported and unreported loss incurred through the balance sheet date. Unpaid loss and loss adjustment are based upon the assumption that past developments are an appropriate indicator of future events. The Incurred But Not Reported (“IBNR”) portion of unpaid loss and loss adjustment expense is based on past experience and other factors. The methods of making such estimates and for establishing the resulting reserves are periodically reviewed and updated. Any resulting adjustments are reflected in income. Unpaid loss and loss adjustment expense consists of the estimated ultimate cost of settling claims incurred within the reporting period (net of related reinsurance recoverable), including IBNR claims, plus changes in estimates of prior period losses. The Company reports its unpaid loss and loss adjustment expense on an undiscounted basis.
The estimation of the liability for unpaid loss and loss adjustment expense is inherently complex and subjective, especially in view of changes in the legal and economic environment, which impact the development of unpaid loss and loss adjustment expense, and therefore quantitative techniques frequently have to be supplemented by subjective considerations and managerial judgment. In addition, trends that have affected development of liabilities in the past may not necessarily occur or affect liability development to the same degree in the future. Therefore, there can be no assurance that the ultimate liability will not materially differ from amounts reserved with a resulting material effect on the operating results of the Company.
The unpaid loss and loss adjustment expense estimate is generally calculated by first projecting the ultimate cost of all claims that have been incurred and then subtracting reported losses and loss adjustment expenses. Reported losses include cumulative paid losses and loss adjustment expenses plus case reserves. Therefore, the IBNR also includes provision for expected development on reported claims.
The Company's actuarial analysis of the historical data provides the factors the Company uses in its actuarial analysis in estimating its loss and loss adjustment reserves. These factors are measures over time of claims reported, average case incurred amounts, case development, severity and payment patterns. However, these factors cannot be directly used as they do not take into consideration changes in business mix, claims management, regulatory issues, and other subjective factors. The Company uses multiple actuarial methods in determining its estimates of the ultimate unpaid claim liabilities. Each of these methods require judgment and assumptions. The methods can include, but are not limited to:
Paid Development Method — uses historical, cumulative paid losses by accident year and develops those actual losses to estimated ultimate losses based upon the assumption that each accident year will develop to estimated ultimate cost in a manner that is analogous to prior years.
Paid Bornhuetter-Ferguson Method — a combination of the Paid Development Method and the Expected Loss Method, the Paid Bornhuetter-Ferguson Method estimates ultimate losses by adding actual paid losses and projected future unpaid losses. The amounts produced are then added to cumulative paid losses to produce the final estimates of ultimate incurred losses.
Incurred Development Method — uses historical, cumulative incurred losses by accident year and develops those actual losses to estimated ultimate losses based upon the assumption that each accident year will develop to estimated ultimate cost in a manner that is analogous to prior years.
Incurred Bornhuetter — Ferguson Method — a combination of the Incurred Development Method and the Expected Loss Method, the Incurred Bornhuetter-Ferguson Method estimates ultimate losses by adding actual incurred losses and projected future unreported losses. The amounts produced are then added to cumulative incurred losses to produce an estimate of ultimate incurred losses.
Expected Loss Method — utilizes an expected ultimate loss ratio based on historical experience adjusted for trends multiplied by earned premium to project ultimate losses.
For each method, losses are projected to the ultimate amount to be paid. The Company then analyzes the results and may emphasize or de-emphasize some or all of the outcomes to reflect actuarial judgment regarding their reasonableness in relation to supplementary information and operational and industry changes. These outcomes are then aggregated to produce a single selected point estimate that is the basis for the actuary's point estimate for loss reserves.
Contingent liabilities
The Company accounts for its contingent liabilities in accordance with ASC Topic 450, Contingencies (“ASC 450”). A provision is recorded when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. With respect to legal matters, provisions are reviewed and adjusted to reflect the impact of negotiations, estimated settlements, legal rulings, advice of legal counsel and other information and events pertaining to a particular matter.
Comprehensive loss
Comprehensive loss includes net loss as well as other changes in stockholders' equity that result from transactions and economic events other than those with stockholders.
Employee related obligations The Company established a defined contribution savings plan under Section 401(k) of the Internal Revenue Code for employees based in the United States. This plan covers substantially all employees who meet minimum age and service requirements and allows participants to defer a portion of their annual compensation on a pre-tax basis. Company contributions to the plan may be made at the discretion of the Company's board of directors.
Revenue
Premium is earned on a pro-rata basis over the term of the related insurance coverage. Unearned premium and prepaid reinsurance premium represent the portion of gross premium written and ceded premium written, respectively, related to the unexpired terms of related policies. Premium ceded to third party reinsurers is reported as a reduction of earned premium.
A premium deficiency is recognized if the sum of expected loss and loss adjustment expense, unamortized acquisition costs, and policy maintenance costs exceeds the remaining unearned premium. A premium deficiency would first be recognized by charging any unamortized acquisition costs to expense to the extent required to eliminate the deficiency. If the premium deficiency were greater than unamortized acquisition costs, a liability would be accrued for the excess deficiency. The Company does not consider anticipated investment income when determining if a premium deficiency exists. There was no premium deficiency as of December 31, 2024 and 2023.
Ceding commission income represents commission received based on premium ceded to third-party reinsurers to reimburse us for acquisition and underwriting expenses. Commissions on reinsurance premium ceded is recorded as earned consistent with the recognition of earned premium on the underlying insurance policies, on a pro-rata basis over the terms of the policies reinsured. The portion of ceding commission income which represents reimbursement of successful acquisition costs related to the underlying policies is recorded as an offset to other insurance expense.
Net investment income represents interest earned from fixed maturity securities, short term securities and other investments, and gains or losses from sale of investments. Investment income is recorded as earned. Investment income consists primarily of interest income which is recognized on an accrual basis. Net investment income represents investment income, net of investment fees paid to the Company’s investment manager and other investment expenses.
Commission income consists of commissions earned on policies written on behalf of third-party insurance companies where the Company has no exposure to the insured risk. Such commission is recognized on the effective date of the associated policy which is when the performance obligation is completed.

Other income consists of fees collected from policyholders relating to installment premiums, and are recognized at the time each policy installment is billed. Other income also includes net realized gains or losses from sale of investments, interest income and sublease income (Note 22).
Other insurance expense
Other insurance expense consists of the amortization of deferred acquisition costs, which includes commissions and premium taxes incurred on the successful acquisition of business written on a direct basis, and merchant processing fees. Other insurance expense also includes employee compensation, including stock-based compensation and benefits, of the Company's underwriting teams, as well as allocated occupancy costs and related overhead costs based on headcount.
Sales and marketing Sales and marketing includes third-party marketing, advertising, branding, public relations and sales expenses. Sales and marketing also includes associated employee compensation, including stock-based compensation and benefits, as well as allocated occupancy costs and related overhead based on headcount. Sales and marketing costs are expensed as incurred.
Technology development
Technology development consists of employee compensation, including stock-based compensation and benefits, and expenses related to vendors engaged in product management, design, development and testing of the Company's websites and products. Technology development also includes allocated occupancy costs and related overhead costs based on headcount. Technology development costs are expensed as incurred, except for costs that are capitalized related to internal-use software development projects which are subsequently depreciated over the expected useful life of the developed software.
General and administrative
General and administrative includes employee compensation, including stock-based compensation and benefits for executive, finance, accounting, legal, business operations and other administrative personnel. In addition, general and administrative includes outside legal, tax and accounting services, non-income based taxes, insurance, charitable donations, and allocated occupancy costs and related overhead costs based on headcount.
Leases
The Company determines whether an arrangement is, or includes, a lease at its inception in accordance with ASC Topic 842, Leases (“ASC 842”). Operating lease liabilities are recognized at the lease commencement date based on the estimated present value of lease payments over the lease term. Right-of-Use (“RoU”) assets are equal to the operating lease liabilities with certain adjustments made for prepaid rent, lease incentives, or initial direct costs, as applicable. Operating lease RoU assets are presented under “Other assets” (Note 12) and Operating lease liabilities are presented under “Other Liabilities and Accrued Expenses” (Note 15). To determine the present value of lease payments, the Company uses an estimated incremental borrowing rate for leases of office spaces, as the rate implicit in the leases is not determinable, which is derived from information available at the lease commencement date. For certain leases that contain options to extend, the options are included in operating lease liabilities only if the Company is reasonably certain that the option will be exercised. Variable lease costs are recorded as expense when the events determining the amount of variable consideration have to be paid have occurred and are not included in the Company’s operating lease liabilities. The Company accounts for the lease and non-lease components as a single lease component for leases for real estate. Operating lease expense is recognized on a straight-line basis over the lease term.
Income from operating subleases where the Company is the sublessor is recognized on a straight-line basis over the lease term, which is presented under “Other Income” in the consolidated statements of operations and comprehensive income.
Operating lease RoU assets are evaluated for impairment at the asset group level whenever events or changes in circumstances indicate that the carrying amount of the asset group may not be recoverable. The carrying amount of an asset group, which includes the operating lease RoU asset is not recoverable if the carrying amount exceeds the sum of the undiscounted cash flows expected to result from the use of the asset group over the life of the primary asset in the asset group. The assessment is based on the carrying amount of the asset group, including the operating lease RoU asset and the related operating lease liability, at the date it is tested for recoverability and an impairment loss is measured and recognized as the amount by which the carrying amount of
the asset group exceeds its fair value. Any impairment loss is allocated to each asset in the asset group, including the operating RoU asset, on a pro-rata basis.
Accounting for stock-based compensation
The Company accounts for stock-based compensation in accordance with ASC Topic 718, Compensation — Stock Compensation (“ASC 718”). Stock options are mainly awarded to employees and members of the Company's board of directors and measured at fair value at each grant date. The Company calculates the fair value of share options on the date of grant using the Black-Scholes option-pricing model and the expense is recognized over the requisite service period for awards expected to vest using the straight-line method. The requisite service period for share options is generally four years. The Company recognizes forfeitures as they occur.
The Black-Scholes option-pricing model requires the Company to make a number of assumptions, including the value of the Company's common stock, expected volatility, expected term, risk-free interest rate and expected dividends. The Company evaluates the assumptions used to value option awards upon each grant of stock options. The expected option term was calculated based on the simplified method, which uses the midpoint between the vesting date and the contractual term, in accordance with ASC 718. The risk-free interest rate is based on observed interest rates appropriate for the term of the Company’s stock options. The dividend yield assumption is based on the Company’s history. The Company has not paid dividends and has no foreseeable plans to pay dividends. For restricted stock awards, the Company utilizes the fair value of the Company’s common stock on the date of grant to establish the fair value of the award.

Nonemployee stock-based compensation transactions in which the Company receives goods or services as consideration for its own equity instruments are accounted for as stock-based compensation transactions. The Company establishes and measures the fair value of these equity instruments at grant date, and is not remeasured. The fair value of a nonemployee award is estimated using the Black-Scholes option pricing model, which uses various inputs including the fair value of the Company’s common stock at grant date, contractual term, estimated volatility, risk-free interest rate and expected dividend yields of the common stock. The Company recognizes compensation expense over the vesting period subject to certain vesting events and thresholds, for each of the installment for a period of five years. The Company does not apply forfeiture for these awards given the nature of the vesting events and thresholds under the agreements (Notes 16 and 17).
Foreign currency
Financial statement accounts expressed in foreign currencies are translated into U.S. dollars. Functional currency assets and liabilities are translated into U.S. dollars generally using rates of exchange prevailing at the balance sheet date of each respective subsidiaries, and the related translation adjustments are recorded as a separate component of accumulated other comprehensive income, net of any related taxes.
Income taxes
The Company accounts for income taxes in accordance with the liability method whereby deferred tax assets and liability account balances are determined based on the differences between financial reporting and the tax basis for assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. The Company provides a valuation allowance, if necessary, to reduce deferred tax assets to the amounts that are more-likely-than-not to be realized. The Company assessed the positive and negative evidence of the realizability of the deferred tax assets amounts and determined that a valuation allowance was required. Accordingly, the Company provided a full valuation allowance against its deferred tax assets as of December 31, 2024 and 2023.
ASC Topic 740, Income Taxes, ("ASC 740") clarifies the accounting for uncertainties in income taxes by establishing minimum standards for the recognition and measurement of tax positions taken or expected to be taken in a tax return. Under the requirements of ASC 740, the Company reviews all of its tax positions and makes a determination as to whether its position is more-likely-than-not to be sustained upon examination by regulatory authorities. If a tax position meets the more-likely-than-not standard, then the related tax benefit is measured based on a cumulative probability analysis of the amount that is more-likely-than-not to be realized upon ultimate settlement or disposition of the underlying issue.
The Company classifies all interest and penalties related to uncertain tax positions as income tax expense.
Net loss per share
Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period. Diluted net loss attributable to common stockholders is computed by adjusting net loss attributable to common stockholders to reallocate undistributed earnings based on the potential impact of dilutive securities. Diluted net loss per share attributable to common stockholders is computed by dividing the diluted net loss attributable to common stockholders by the weighted average number of common shares outstanding for the period, including potential dilutive common shares. For purpose of this calculation, outstanding stock options and assumed warrants to purchase common shares of the Company are considered potential dilutive common shares.
In periods in which the Company reports a net loss attributable to common stockholders, diluted net loss per share attributable to common stockholders is the same as basic net loss per share attributable to common stockholders, since dilutive common shares are not assumed to have been issued if their effect is anti-dilutive. The Company reported a net loss attributable to common stockholders for the years ended December 31, 2024, 2023 and 2022.

The unvested portion of fair value attributable to these replacement awards of $4.3 million comprised of $0.1 million for assumed options and $4.2 million for assumed restricted stock units ("RSUs"), and associated with future service will be recognized as expense over the future service period.
