Gross premiums earned under Insurance Operations include $ 2,891 earned from the reciprocal exchange operations. The income (loss) before income taxes in the reclassification/elimination column is attributable to intercompany transactions among operating segments. The insurance operations and the reciprocal exchange operations record service fee expenses based on earned premiums or other appropriate measures, while TypTap Group and the AIF operations recognize service fee revenues according to revenue recognition standards. Although both service fee expenses and revenues are fully eliminated on consolidation, they do not completely offset each other in this presentation due to the different methods of recognition.

Pursuant to the Purchase Agreement, TTIG transferred to HCI 2,500,000 shares of TypTap's $ 1.00 par value common stock which represented all of the issued and outstanding capital stock of TypTap. In exchange, HCI agreed to consider three promissory notes issued by TTIG, totaling $ 117,994 in principal, as fully repaid with the exception of a 2.00 % promissory note due June 1, 2025 . This promissory note will remain in effect with its principal balance reduced from $ 40,000 to $ 2,994 . As this was a transaction between entities under common control with no ultimate change in control of TypTap, the purchase was accounted for as a common control transaction. The net assets of TypTap were derecognized by TTIG and recognized by HCI at their carrying amounts on the date of the purchase. The difference between the consideration transferred and the carrying amounts of the net assets was recognized in equity. As there was no change in HCI’s ownership percentage in TTIG, the change in noncontrolling interests in TTIG was charged to noncontrolling interest expense. This organizational change was implemented to align all insurance operations under a single operating segment under the Company’s direct control, allowing TTIG to primarily focus on its industry-leading technology and insurance management activities as an insurance solutions provider. As a result of this transaction, the former HCPCI Insurance Operations segment is changed to the Insurance Operations segment. TypTap’s financial information is now included in this segment, allowing for the presentation of all insurance operations under a single segment. See Note 14 -- “Segment Information” for additional information. Impact of Hurricane Helene On September 26, 2024, Hurricane Helene made landfall in the Big Bend area of Florida as a powerful Category 4 storm. The storm continued inland impacting Georgia, South Carolina, and North Carolina, among other states. The Company estimated its consolidated gross losses, including loss adjustment expenses, at $ 61,000 . After anticipated reinsurance recoveries, net losses are estimated to be $ 40,000 . For details of the impact on the Company's multi-year reinsurance contract with retrospective provisions, see Note 11 -- “Reinsurance.” Assumed Business Citizens Assumption The Company participated in a take-out program through which the Company assumed insurance policies held by Citizens Property Insurance Corporation (“Citizens”), a Florida state-supported insurer. There were no policies assumed during the third quarter of 2024. During the nine months ended September 30, 2024 , approximately 10,100 policies were assumed by TypTap and CORE. These policies represent approximately $ 120,100 in annualized premiums written.

Accounting Policies [Abstract]
Summary of Significant Accounting Policies	Note 2 -- Summary of Significant Accounting Policies Basis of Presentation The accompanying unaudited consolidated financial statements of HCI Group, Inc. and its majority-owned and controlled subsidiaries (collectively, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information, and the Securities and Exchange Commission (“SEC”) rules for interim financial reporting. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to such rules and regulations. However, in the opinion of management, the accompanying consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the Company’s financial position as of September 30, 2024 and the results of operations and cash flows for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of the results of operations to be expected for any subsequent interim period or for the fiscal year ending December 31, 2024. The accompanying unaudited consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2023 included in the Company’s Form 10-K, which was filed with the SEC on March 8, 2024. In preparing the interim unaudited consolidated financial statements, management was required to make certain judgments, assumptions, and estimates that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures at the financial reporting date and throughout the periods being reported upon. Certain of the estimates result from judgments that can be subjective and complex, and consequently actual results may differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term are related to the Company’s losses and loss adjustment expenses, which include amounts estimated for claims incurred but not yet reported. The Company uses various assumptions and actuarial data it believes to be reasonable under the circumstances to make these estimates. In addition, accounting policies specific to reinsurance with retrospective provisions, reinsurance recoverable, deferred income taxes, limited partnership investments, allowance for credit losses, and stock-based compensation expense involve significant judgments and estimates material to the Company’s consolidated financial statements. In the case of assumed business, the Company relies entirely on the ceding insurance company to provide information about premiums, losses, and loss adjustment expenses. When the information is not available at the reporting date, the Company will make estimates based on all recent available data. Accordingly, the actual results could differ significantly from those estimates. All significant intercompany balances and transactions have been eliminated. Revenue from Claims Processing Services Revenue related to claims processing services is included in other revenue in the consolidated statements of income. For the three and nine months ended September 30, 2024 , revenues from claims processing services were $ 0 in each period. For the three and nine months ended September 30, 2023 , revenues from claims processing services were $ 4 and $ 708 , respectively. Redeemable Noncontrolling Interests Redeemable noncontrolling interests represent economic interests in TTIG and CORE not held by HCI. They are presented in the temporary equity (mezzanine) section of the consolidated balance sheets. TTIG The interest in TTIG contains rights in dividends, voting, conversion, participation, liquidation preference and redemption. The redemption feature is not solely within the control of TTIG. The interest is initially recorded at fair value and is decreased by related issuance costs. The fair value is estimated using a residual fair value approach. The effect of increasing dividend rates is accreted to the redeemable noncontrolling interest with a corresponding reduction in retained income. The effective interest method is used for accretion over the period of the increasing dividend rates. The carrying value of the interest is also subsequently adjusted for accrued dividends and dividend payments. The Company has an option to pay the dividends in cash or make a payment-in-kind. The dividends are accrued monthly assuming they will be settled in cash. When the interest is probable of becoming redeemable, the Company elects to recognize changes in the redemption value immediately as it occurs and adjusts the carrying value of the interest to the maximum redemption value which is the higher of the redemption price or fair market value at the reporting date. Such changes in the redemption value are treated as dividends when calculating income available to common stockholders. CORE The interest in CORE represents a refundable portion of CORE’s subscriber surplus contributions. CORE, a reciprocal insurance exchange, collects surplus contributions in addition to policy premiums from its policyholders referred to as subscribers. The purpose of the surplus contribution is to support CORE’s financial strength and lower CORE’s cost of capital. The surplus contribution made during a policy term may be returned on a pro-rata basis to a subscriber in the event of policy cancellation. As the term of an insurance policy progresses, a portion of the surplus contribution is reclassified from the redeemable noncontrolling interest to the noncontrolling interest. Noncontrolling Interests The Company has noncontrolling interests attributable to TTIG and CORE. A noncontrolling interest arises when the Company has less than 100 % of the voting rights and economic interests in a subsidiary or a consolidated variable interest entity. The noncontrolling interest in TTIG is periodically adjusted for the expensing of TTIG’s stock-based awards granted to its employees, the interest’s share of TTIG’s net income or loss attributable to common stockholders and the change in other comprehensive income or loss. The noncontrolling interest in CORE is periodically adjusted for the interest’s share of CORE’s net income or loss attributable to common stockholders and the reclassification of surplus contributions from refundable to nonrefundable amount. Reclassification As a result of the transaction described in Change in Segment Information under Note 1 -- “Nature of Operations,” the Company’s previously reported segment information has been recast to conform with the current presentation. See Note 14 -- “Segment Information. ”

Allowance for Credit Losses of Available-for-Sale Fixed-Maturity Securities The Company regularly reviews its individual investment securities for credit impairment. The Company considers various factors in determining whether a credit loss exists for each individual security, including- • the financial condition and near-term prospects of the issuer, including any specific events that may affect its operations or earnings; • the extent to which the market value of the security has been below its cost or amortized cost; • general market conditions and industry or sector specific factors and other qualitative factors; • nonpayment by the issuer of its contractually obligated interest and principal payments; and • the Company’s intent and ability to hold the investment for a period of time sufficient to allow for the recovery of costs. There was no balance or activity in th e allowance for credit losses of available-for-sale fixed-maturity securities during the three and nine months ended September 30, 2024 and 2023. b) Equity Securities The Company holds investments in equity securities measured at fair values which are readily determinable.

The lease was considered to be at a below market rate. The value of the below market lease was recognized as deferred rent and amortized to rental income over the lease term. In June 2024, the tenant occupying the property under a sublease agreement with the seller vacated the property. As a result, the Company derecognized the remaining deferred rent to rental income. For the nine months ended September 30, 2024 , income from real estate investments included rental income of $ 2,497 resulting from such derecognition of deferred rent. For the nine months ended September 30, 2023 , income from real estate investments included a net gain of $ 6,476 resulting from the sale of the retail shopping center investment property in Melbourne, Florida in March 2023 for a price of $ 18,500 , and included a net gain of $ 2,460 resulting from the sale of the retail shopping center investment property in Sorrento, Florida in March 2023 for a price of $ 13,418 .

For the three and nine months ended September 30, 2024, net realized gains relat ed to other investments were $ 3 in each period. For the three and nine months ended September 30, 2023 , net realized gains were $ 0 and $ 47 , respectively.

Fair Value Measurements

Fair Value Measurements	9 Months Ended

Fair Value Disclosures [Abstract]
Fair Value Measurements	Note 6 -- Fair Value Measurements The Company records and discloses certain financial assets at their estimated fair values. The fair value hierarchy prioritizes the inputs to valuation techniques used to measure fair value into three broad levels as follows: Level 1 – Unadjusted quoted prices in active markets for identical assets. Level 2 – Other inputs that are observable for the asset, either directly or indirectly such as quoted prices for identical assets that are not observable throughout the full term of the asset. Level 3 – Inputs that are unobservable. Valuation Methodology Cash and Cash Equivalents Cash and cash equivalents primarily consist of money-market funds and certificates of deposit maturing within 90 days. Their carrying value approximates fair value due to the short maturity and high liquidity of these funds. Restricted Cash Restricted cash represents cash held by state authorities and the carrying value approximates fair value. Fixed-Maturity and Equity Securities Estimated fair values of the Company’s fixed-maturity and equity securities are determined in accordance with U.S. GAAP, using valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. Fair values are generally measured using quoted prices in active markets for identical securities or other inputs that are observable either directly or indirectly, such as quoted prices for similar securities. In those instances where observable inputs are not available, fair values are measured using unobservable inputs. Unobservable inputs reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the security and are developed based on the best information available in the circumstances. Fair value estimates derived from unobservable inputs are significantly affected by the assumptions used, including the discount rates and the estimated amounts and timing of future cash flows. The derived fair value estimates cannot be substantiated by comparison to independent markets and are not necessarily indicative of the amounts that would be realized in a current market exchange. The estimated fair values for securities that do not trade on a daily basis are determined by management, utilizing prices obtained from an independent pricing service and information provided by brokers, which are level 2 inputs. Management reviews the assumptions and methods utilized by the pricing service and then compares the relevant data and pricing to broker-provided data. The Company gains assurance of the overall reasonableness and consistent application of the assumptions and methodologies, and compliance with accounting standards for fair value determination through ongoing monitoring of the reported fair values. Revolving Credit Facility From time to time, the Company has an amount outstanding under a revolving credit facility. The interest rate is variable and is periodically adjusted based on the Secured Overnight Financing Rate (“SOFR”) plus a ten basis points adjustment plus a margin based on the debt-to-capital ratio. As a result, carrying value, when outstanding, approximates fair value.

Insurance [Abstract]
Reinsurance	Note 11 -- Reinsurance Reinsurance obtained from other insurance companies The Company cedes a portion of its homeowners’ insurance exposure to other entities under catastrophe excess of loss reinsurance contracts and a portion of its flood insurance exposure under one quota share reinsurance agreement. Ceded premiums under most catastrophe excess of loss reinsurance contracts are subject to revision resulting from subsequent adjustments in total insured value. Under the terms of the quota share reinsurance agreement, the Company is entitled to a 30 % ceding commission on ceded premiums written and a profit commission equal to 10 % of net profit. The Company remains liable for claims payments in the event that any reinsurer is unable to meet its obligations under the reinsurance agreements. Failure of reinsurers to honor their obligations could result in losses to the Company. The Company evaluates the financial condition of its reinsurers and monitors concentrations of credit risk arising from similar geographic regions, activities or economic characteristics of the reinsurers to minimize its exposure to significant losses from reinsurer insolvencies. The Company contracts with a number of reinsurers to secure its annual reinsurance coverage, which generally becomes effective June 1 st of each year. The Company purchases reinsurance each year taking into consideration probable maximum losses and reinsurance market conditions. The impact of the reinsurance contracts on premiums written and earned is as follows: Three Months Ended Nine Months Ended September 30, September 30, 2024 2023 2024 2023 Premiums Written: Direct $ 270,979 $ 198,265 $ 767,163 $ 585,671 Assumed ( 600 ) — 65,104 ( 7,569 ) Gross written 270,379 198,265 832,267 578,102 Ceded ( 109,694 ) ( 66,152 ) ( 254,513 ) ( 203,051 ) Net premiums written $ 160,685 $ 132,113 $ 577,754 $ 375,051 Premiums Earned: Direct $ 229,876 $ 188,308 $ 621,342 $ 543,159 Assumed 35,642 — 164,381 7,163 Gross earned 265,518 188,308 785,723 550,322 Ceded ( 109,694 ) ( 66,152 ) ( 254,513 ) ( 203,051 ) Net premiums earned $ 155,824 $ 122,156 $ 531,210 $ 347,271 During the three and nine months ended September 30, 2024, the Company recognized ceded losses of $ 21,981 and $ 24,653 , respectively, as reductions in losses and loss adjustment expenses. During the three and nine months ended September 30, 2023 , the Company recognized ceded losses of $ 2,911 and $ 6,771 , respectively, as reductions in losses and loss adjustment expenses. At September 30, 2024 and December 31, 2023 , there were 44 and 33 reinsurers, respectively, participating in the Company’s reinsurance program. Total net amounts recoverable and receivable from reinsurers at September 30, 2024 and December 31, 2023 were $ 300,571 and $ 350,294 , respectively. Approximatel y 68.2 % of the paid reinsurance recoverable balance at September 30, 2024 was receivable from five reinsurers. Based on all available information considered in the rating-based method, the Company recogn ized decreases in credit loss expense of $ 20 and $ 72 for the three and nine months ended September 30, 2024, respectively. For the three and nine months ended September 30, 2023 , the Company recognized decreases in credit loss expense of $ 33 and $ 135 , respectively. Allowances for credit losses related to the reinsurance recoverable balance were $ 46 and $ 118 at September 30, 2024 and December 31, 2023, respectively. One of the existing reinsurance contracts includes retrospective provisions that adjust premiums in the event losses are minimal or zero. As a result of Hurricane Helene, the balance of previously accrued benefits under the multi-year reinsurance contract with retrospective provisions was decreased by $ 12,369 during the third quarter of 2024. For the three months ended September 30, 2024 , the Company derecognized reductions in premiums ceded of $ 7,707 related to these adjustments in the consolidated statement of income. For the nine months ended September 30, 2024, the Company recognized reductions in premiums ceded of $ 6,279 . For the three and nine months ended September 30, 2023 , the Company recognized reductions in premiums ceded of $ 6,993 and $ 20,979 , respectively. Amounts receivable pursuant to retrospective provisions are reflected in other assets. At September 30, 2024 and December 31, 2023 , other assets included $ 50,568 and $ 44,289 , respectively, of amounts receivable pursuant to retrospective provisions. Management believes the credit risk associated with the collectability of these accrued benefits is minimal as the amount receivable is concentrated wit h one reinsurer with a good credit rating and the Company monitors the creditworthiness of this reinsurer based on available information about the reinsurer’s financial condition. See Note 23 -- “Subsequent Events” for additional information. Reinsurance provided to other insurance companies United From 2021 to 2022, the Company, through HCPCI and TypTap, provided quota share reinsurance on all in-force, new and renewal policies issued by United Property & Casualty Insurance Company, an insurance subsidiary of United Insurance Holdings Corporation (“United”), in the states of Connecticut, New Jersey, Massachusetts, and Rhode Island (collectively “Northeast Region”). From 2022 to 2023, the Company’s insurance subsidiaries also provided quota share reinsurance on all of United’s personal lines insurance business in the states of Georgia, North Carolina, and South Carolina (collectively “Southeast Region”). In conjunction with these reinsurance agreements, the Company entered into renewal rights agreements with United which provided the Company with the right to renew and/or replace United’s insurance policies at the end of their respective policy periods. In February 2023, United’s Florida-domiciled residential insurance subsidiary was placed into receivership by the State of Florida due to its financial insolvency and, as a result, the Company ceased providing quota share reinsurance on United policies. The majority of the policies under these reinsurance agreements have been renewed and/or replaced by the Company. At September 30, 2024 and December 31, 2023, the Company had a net balance o f $ 582 d ue to United related to the Northeast Region, representing ceding commission payable. For the three and nine months ended September 30, 2023 , $ 0 and $ 7,569 , respectively, of assumed premiums written related to the Southeast Region’s insurance policies were derecognized, primarily resulting from the return of the unearned portion of assumed written premiums subsequent to the Company's renewal and/or replacement of insurance policies in the Southeast Region. At September 30, 2024, the Company had a net balance of $ 1,438 due to United related to the Southeast Region, consisting of premiums payable of $ 1,712 , offset by ceding commission receivable of $ 274 . At December 31, 2023, the Company had a net balance of $ 4,203 due to United related to the Southeast Region, consisting of premiums payable of $ 1,712 and payable on paid losses and loss adjustment expenses of $ 2,765 , offset by ceding commission receivable of $ 274 . At September 30, 2024, the Company had a net amount due to United of $ 2,020 and funds withheld for assumed business in trust accounts totaling $ 14,527 for the benefit of policies assumed from United. The Company ceased providing TPA services to United in March 2023. The Company cannot predict the actions a receiver might take, which may include restrictions on, or use of, funds held in trust. Any such actions could have a material adverse effect on the Company’s financial position and results of operations. At September 30, 2024 and December 31, 2023 , the balance of funds withheld for assumed business related to the Company’s quota share reinsurance agreements with United was $ 14,527 and $ 30,087 , respectively.

Insurance [Abstract]
Losses and Loss Adjustment Expenses	Note 12 -- Losses and Loss Adjustment Expenses The liability for losses and loss adjustment expenses (“LAE”) is determined on an individual case basis for all claims reported. The liability also includes amounts for unallocated expenses, anticipated future claims development and losses incurred but not reported. The Company primarily writes insurance in states which could be exposed to hurricanes or other natural catastrophes. The occurrence of a major catastrophe could have a significant effect on the Company’s quarterly results and cause a temporary disruption of the normal operations of the Company. However, the Company is unable to predict the frequency or severity of any such events that may occur in the near term or thereafter. Activity in the liability for losses and LAE is summarized as follows: Three Months Ended Nine Months Ended September 30, September 30, 2024 2023 2024 2023 Net balance, beginning of period* $ 291,785 $ 243,586 $ 254,351 $ 246,546 Incurred, net of reinsurance, related to: Current period 110,510 58,621 263,938 176,287 Prior periods ( 4,774 ) 8,105 44 12,894 Total incurred, net of reinsurance 105,736 66,726 263,982 189,181 Paid, net of reinsurance, related to: Current period ( 36,942 ) ( 36,299 ) ( 86,502 ) ( 74,514 ) Prior periods ( 21,324 ) ( 27,782 ) ( 92,576 ) ( 114,982 ) Total paid, net of reinsurance ( 58,266 ) ( 64,081 ) ( 179,078 ) ( 189,496 ) Net balance, end of period 339,255 246,231 339,255 246,231 Add: reinsurance recoverable before allowance for 273,099 462,858 273,099 462,858 Gross balance, end of period $ 612,354 $ 709,089 $ 612,354 $ 709,089 * Net balance represents beginning-of-period liability for unpaid losses and LAE less beginning-of-period reinsurance recoverable for unpaid losses and LAE. The establishment of loss and LAE reserves is an inherently uncertain process and changes in loss and LAE reserve estimates are expected as these estimates are subject to the outcome of future events. Changes in estimates, or differences between estimates and amounts ultimately paid, are reflected in the operating results of the period during which such estimates are adjusted. During the three months ended September 30, 2024, the Company lowered its reserves related to prior periods by $ 4,774 due to positive development trends . Due to Hurricane Helene, the Company incurred net estimated losses of approximately $ 40,000 during the third quarter of 2024. Excluding Hurricane Helene-related losses, losses and LAE for the three and nine months ended September 30, 2024 included net estimated losses of approximately $ 1,250 and $ 37,250 , respectively, related to Citizens policies assumed.

Variable Interest Entity, Measure of Activity [Abstract]
Variable Interest Entity	Note 13 -- Variable Interest Entity CORE, a Florida-domiciled reciprocal insurance exchange, is owned by its policyholders, referred to as subscribers, and was organized to offer commercial residential multiple peril and wind insurance products. Each subscriber owns part of CORE by buying an insurance policy and making a surplus contribution. CORE is managed by CRM, an AIF company which is a wholly-owned subsidiary of HCI. At the formation date of CORE, management determined that CORE is a variable interest entity (“VIE”). HCI is required to assess whether it has a controlling financial interest in CORE. A controlling financial interest exists if an entity has both: 1) the power to direct the activities of the VIE that most significantly impact the VIE’s economic performance, and 2) the obligation to absorb losses from or the right to receive benefits of the VIE that could potentially be significant to the VIE. Under U.S. GAAP, an entity meeting these requirements is considered to be the primary beneficiary of a VIE and is required to consolidate the VIE. Since in the judgment of management, HCI meets these requirements via the management and service agreements and the subordinated surplus note, HCI is required to consolidate CORE. Further, as HCI has no equity at risk, CORE’s equity and results of operations are included in noncontrolling interests. In the event of dissolution, subscribers will participate in the distribution of any remaining equity without being liable for any shortfall in CORE's equity. CORE’s assets are legally restricted for the purpose of fulfilling obligations specific to CORE. The creditors of CORE have no legal right to pursue additional sources of payment from the Company. The following table summarizes the assets and liabilities related to CORE, a consolidated VIE, which are included in the accompanying consolidated balance sheets: September 30, December 31, 2024 2023 Assets: Cash and cash equivalents $ 54,431 $ 24,635 Restricted cash 308 300 Income taxes receivable 977 — Premiums receivable 3,804 — Prepaid reinsurance premium 6,047 — Deferred policy acquisition costs 2,253 — Other assets 583 65 Total assets $ 68,403 $ 25,000 Liabilities: Losses and loss adjustment expenses $ 4,497 $ — Unearned premiums 33,117 — Advance premiums 105 — Ceded reinsurance premiums payable 1,582 — Assumed premiums payable 99 — Accrued expenses 974 — Deferred income taxes, net 450 — Other liabilities 312 — Total liabilities $ 41,136 $ —

Segment Reporting [Abstract]
Segment Information	Note 14 -- Segment Information The Company identifies its operating divisions based on managerial emphasis, organizational structure and revenue source. With the transaction described in Change in Segment Information under Note 1 -- “Nature of Operations,” the Company now operates under five reportable segments: insurance operations, TypTap Group, reciprocal exchange operations, real estate operations, and corporate and other. Due to their economic characteristics, the Company’s property and casualty insurance division and reinsurance operations, excluding the insurance operations under reciprocal exchange operations, are grouped together into one reportable segment under insurance operations. The TypTap Group segment includes information technology operations, insurance management service operations, and its management company’s activities. The reciprocal exchange segment represents the insurance operations of CORE, a consolidated VIE. The real estate operations segment includes companies engaged in operating commercial properties the Company owns for investment purposes or for use in its own operations. The corporate and other segment represents the activities of the holding companies and any other companies, such as CRM, that do not meet the quantitative and qualitative thresholds for a reportable segment. The determination of segments may change over time due to changes in operational emphasis, revenues, and results of operations. The Company’s chief executive officer, who serves as the Company’s chief operating decision maker, evaluates each division’s financial and operating performance based on revenue and operating income. For the three months ended September 30, 2024 and 2023, revenues from the insurance operations segment before intracompany elimination represented 82.7 % and 87.6 %, respectively, and revenues from the TypTap Group segment represented 11.0 % and 11.0 %, respectively, of total revenues of all operating segments. For the nine months ended September 30, 2024 and 2023, revenues from the insurance operations segment before intracompany elimination represented 84.5 % an d 86.9 %, respectively, and revenues from the TypTap Group segment represented 10.8 % a nd 11.6 %, respectively, of total revenues of all operating segments.

Income Tax Disclosure [Abstract]
Income Taxes	Note 16 -- Income Taxes A valuation allowance must be established for deferred tax assets when it is more likely than not that the deferred tax assets will not be realized based on available evidence both positive and negative, including recent operating results, available tax planning strategies, and projected future taxable income. The Company evaluates the realizability of its deferred tax assets each quarter, and as of September 30, 2024, based on all of the available evidence, management concluded that it is more likely than not that the deferred tax assets will be realized other than a valuation allowance on the sale of TTIC by TTIG to HCI in the amount of $ 133 related to the deferred intercompany taxable loss that arose during the third quarter of 2024. During the three months ended September 30, 2024 and 2023 , the Company recorded approximately $ 4,688 and $ 4,419 of income tax expense, respectively, resulting in effective tax rates of 33.3 % and 22.0 %, respectively. The increase in the effective tax rate as compared with the corresponding period in the prior year was primarily attributable to a lower prior year effective tax rate resulting from the release of the valuation allowance during 2023 and a higher effective tax rate resulting from certain non-deductible compensation expense for the third quarter of 2024. During the nine months ended September 30, 2024 and 2023 , the Company recorded approximately $ 44,089 and $ 15,146 of income tax expense, respectively, resulting in effective tax rates of 26.3 % and 23.9 %, respectively. The increase in the effective tax rate as compared with the corresponding period in the prior year was primarily attributable to a lower prior year effective tax rate resulting from the release of the valuation allowance during 2023 and a higher effective tax rate resulting from certain non-deductible compensation expense for the third quarter of 2024. The Company’s estimated annual effective tax rate differs from the statutory federal tax rate due to state and foreign income taxes as well as certain non-deductible and tax-exempt items.

Earnings Per Share [Abstract]
Earnings Per Share	Note 17 -- Earnings Per Share U.S. GAAP requires the Company to use the two-class method in computing basic earnings (loss) per share since holders of the Company’s restricted stock have the right to share in dividends, if declared, equally with common stockholders. These participating securities affect the computation of both basic and diluted earnings (loss) per share during periods of net income or loss. For a majority-owned subsidiary, its basic and diluted earnings (loss) per share are first computed separately. Then, the Company’s proportionate share in that majority-owned subsidiary’s earnings is added to the computation of both basic and diluted earnings (loss) per share at a consolidated level. A summary of the numerator and denominator of the basic and diluted earnings per common share is presented below: Three Months Ended Three Months Ended September 30, 2024 September 30, 2023 Income Shares (a) Per Share Income Shares (a) Per Share (Numerator) (Denominator) Amount (Numerator) (Denominator) Amount Net income $ 9,392 $ 15,669 Less: Net income attributable to — ( 2,349 ) Less: Net income attributable ( 3,710 ) ( 163 ) Net income attributable to HCI 5,682 13,157 Less: Income attributable to ( 230 ) ( 411 ) Basic Earnings Per Share: Income allocated to common 5,452 10,050 $ 0.54 12,746 8,317 $ 1.53 Effect of Dilutive Securities: * Stock options — 269 — 88 Convertible senior notes — — 1,927 2,538 Warrants — 192 — 32 Diluted Earnings Per Share: Income available to common $ 5,452 10,511 $ 0.52 $ 14,673 10,975 $ 1.34 (a) Shares in thousands . * For the three months ended September 30, 2024 , convertible senior notes were excluded due to anti-dilutive effect.

Equity	Note 19 -- Equity Stockholders’ Equity Common Stock On January 22, 2024, a new shelf registration statement on Form S-3 (the “Shelf Registration”) was filed, replacing the Company’s old universal shelf registration statement filed in September 2023. The new Shelf Registration permits the Company to offer and sell its common stock, preferred stock, debt securities, warrants, and stock purchase contracts and units, from time to time, subject to market conditions and its capital needs. The Shelf Registration will also enable Centerbridge to sell all or a portion of the amended and restated warrant or the shares issuable pursuant to the warrant. As a part of the Shelf Registration, the Company also announced the implementation of an “at-the-market” facility (the “ATM facility”) under which the Company would have the ability to raise up to $ 75,000 through the issuance of new shares of common stock into the market if it were to so choose. On July 3, 2024 , the Company’s Board of Directors declared a quarterly dividend of $ 0.40 per common share.

The terms of the Company’s outstanding restricted stock grants may include service, performance, and market-based conditions. The determination of fair value with respect to the awards containing only service-based conditions is based on the market value of the Company’s common stock on the grant date. For awards with market-based conditions, the fair value is determined using a Monte Carlo simulation method, which calculates many potential outcomes for an award and then establishes fair value based on the most likely outcome.

Summary of Significant Accoun_2

Summary of Significant Accounting Policies (Policies)	9 Months Ended
	Sep. 30, 2024
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The accompanying unaudited consolidated financial statements of HCI Group, Inc. and its majority-owned and controlled subsidiaries (collectively, the “Company”) have been prepared in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”) for interim financial information, and the Securities and Exchange Commission (“SEC”) rules for interim financial reporting. Certain information and footnote disclosures normally included in consolidated financial statements prepared in accordance with U.S. GAAP have been omitted pursuant to such rules and regulations. However, in the opinion of management, the accompanying consolidated financial statements reflect all normal recurring adjustments necessary to present fairly the Company’s financial position as of September 30, 2024 and the results of operations and cash flows for the interim periods presented. The results of operations for the interim periods presented are not necessarily indicative of the results of operations to be expected for any subsequent interim period or for the fiscal year ending December 31, 2024. The accompanying unaudited consolidated financial statements and notes thereto should be read in conjunction with the audited consolidated financial statements for the year ended December 31, 2023 included in the Company’s Form 10-K, which was filed with the SEC on March 8, 2024. In preparing the interim unaudited consolidated financial statements, management was required to make certain judgments, assumptions, and estimates that affect the reported amounts of assets, liabilities, revenues, expenses and related disclosures at the financial reporting date and throughout the periods being reported upon. Certain of the estimates result from judgments that can be subjective and complex, and consequently actual results may differ from these estimates. Material estimates that are particularly susceptible to significant change in the near term are related to the Company’s losses and loss adjustment expenses, which include amounts estimated for claims incurred but not yet reported. The Company uses various assumptions and actuarial data it believes to be reasonable under the circumstances to make these estimates. In addition, accounting policies specific to reinsurance with retrospective provisions, reinsurance recoverable, deferred income taxes, limited partnership investments, allowance for credit losses, and stock-based compensation expense involve significant judgments and estimates material to the Company’s consolidated financial statements. In the case of assumed business, the Company relies entirely on the ceding insurance company to provide information about premiums, losses, and loss adjustment expenses. When the information is not available at the reporting date, the Company will make estimates based on all recent available data. Accordingly, the actual results could differ significantly from those estimates. All significant intercompany balances and transactions have been eliminated.
Redeemable Noncontrolling Interest	Redeemable Noncontrolling Interests Redeemable noncontrolling interests represent economic interests in TTIG and CORE not held by HCI. They are presented in the temporary equity (mezzanine) section of the consolidated balance sheets. TTIG The interest in TTIG contains rights in dividends, voting, conversion, participation, liquidation preference and redemption. The redemption feature is not solely within the control of TTIG. The interest is initially recorded at fair value and is decreased by related issuance costs. The fair value is estimated using a residual fair value approach. The effect of increasing dividend rates is accreted to the redeemable noncontrolling interest with a corresponding reduction in retained income. The effective interest method is used for accretion over the period of the increasing dividend rates. The carrying value of the interest is also subsequently adjusted for accrued dividends and dividend payments. The Company has an option to pay the dividends in cash or make a payment-in-kind. The dividends are accrued monthly assuming they will be settled in cash. When the interest is probable of becoming redeemable, the Company elects to recognize changes in the redemption value immediately as it occurs and adjusts the carrying value of the interest to the maximum redemption value which is the higher of the redemption price or fair market value at the reporting date. Such changes in the redemption value are treated as dividends when calculating income available to common stockholders. CORE The interest in CORE represents a refundable portion of CORE’s subscriber surplus contributions. CORE, a reciprocal insurance exchange, collects surplus contributions in addition to policy premiums from its policyholders referred to as subscribers. The purpose of the surplus contribution is to support CORE’s financial strength and lower CORE’s cost of capital. The surplus contribution made during a policy term may be returned on a pro-rata basis to a subscriber in the event of policy cancellation. As the term of an insurance policy progresses, a portion of the surplus contribution is reclassified from the redeemable noncontrolling interest to the noncontrolling interest.
Noncontrolling Interests	Noncontrolling Interests The Company has noncontrolling interests attributable to TTIG and CORE. A noncontrolling interest arises when the Company has less than 100 % of the voting rights and economic interests in a subsidiary or a consolidated variable interest entity. The noncontrolling interest in TTIG is periodically adjusted for the expensing of TTIG’s stock-based awards granted to its employees, the interest’s share of TTIG’s net income or loss attributable to common stockholders and the change in other comprehensive income or loss. The noncontrolling interest in CORE is periodically adjusted for the interest’s share of CORE’s net income or loss attributable to common stockholders and the reclassification of surplus contributions from refundable to nonrefundable amount.
Revenue from Claims Processing Services	Revenue from Claims Processing Services Revenue related to claims processing services is included in other revenue in the consolidated statements of income. For the three and nine months ended September 30, 2024 , revenues from claims processing services were $ 0 in each period. For the three and nine months ended September 30, 2023 , revenues from claims processing services were $ 4 and $ 708 , respectively.
Reclassification	Reclassification As a result of the transaction described in Change in Segment Information under Note 1 -- “Nature of Operations,” the Company’s previously reported segment information has been recast to conform with the current presentation. See Note 14 -- “Segment Information.
