Basis of Presentation and Significant Accounting Policies	3 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation and Significant Accounting Policies	Basis of Presentation and Significant Accounting Policies Business Horace Mann Educators Corporation is a holding company for insurance subsidiaries that market and underwrite personal lines of property and casualty insurance products (primarily personal lines of auto and property insurance), life insurance products, retirement products (primarily tax-qualified fixed and variable annuities), individual supplemental insurance products (primarily cancer, heart, hospital, supplemental disability and accident coverages), and group benefit products (primarily short-term and long-term group disability, and group term life coverages), primarily to K-12 teachers, administrators and other employees of public schools and their families (collectively, HMEC, the Company or Horace Mann). The Company conducts and manages its business in four reporting segments: (1) Property & Casualty, (2) Life & Retirement, (3) Supplemental & Group Benefits and (4) Corporate & Other. Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) and with the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in annual financial statements prepared in conformity with GAAP, but are not required for interim reporting purposes, have been omitted. These Consolidated Financial Statements and Notes thereto should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in Part II - Item 8 of the Company's Annual Report on Form 10-K for the year ended December 31, 2024. The results of operations for the three months ended March 31, 2025 are not necessarily indicative of the results to be expected for the full year. The accompanying Consolidated Financial Statements and Notes thereto are unaudited and reflect all adjustments (generally consisting only of normal recurring accruals) which are, in the opinion of management, necessary for the fair presentation of the consolidated financial position, results of operations and cash flows for the interim periods. The Company's significant accounting policies are summarized in Part II - Item 8, Note 1 of the Consolidated Financial Statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2024. The Company has reclassified the presentation of certain prior period information to conform to the current year's presentation. Consolidation All intercompany transactions and balances between HMEC and its subsidiaries and affiliates have been eliminated. Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the reporting date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. The most significant critical accounting estimates include valuation of hard-to-value fixed maturity securities, evaluation of credit loss impairments for fixed maturity securities, valuation of future policy benefit reserves, and valuation of liabilities for property and casualty unpaid claims and claim expense reserves. Future Adoption of New Accounting Standards Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This update will improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. This guidance will be effective for the Company for annual periods beginning after December 15, 2024 and interim periods beginning after December 15, 2025. Early adoption is permitted. The guidance will have no net impact on the Company's consolidated financial position, results of operations, or cash flows. Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU 2024-04, 03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This guidance will improve the disclosures regarding a public business entity’s expenses by requiring (1) disclosure of the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil and gas-producing activities (or other amounts of depletion expense) included in each relevant expense caption, (2) inclusion of certain amounts that are already required to be disclosed under current generally accepted accounting principles (GAAP) in the same disclosure as the other disaggregation requirements, (3) disclosure of a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively and (4) disclosure of the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The amendments in this guidance will be effective for the Company for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The guidance will have no net impact on the Company's consolidated financial position, results of operations, or cash flows.

The Company, from time to time, sells fixed maturity securities subsequent to the reporting date but prior to the issuance of the financial statements that were in an unrealized loss position but no credit loss was recognized and there was no intent to sell the securities at the reporting date. Such sales are due to issuer-specific events

occurring subsequent to the reporting date that result in a change in the Company's intent to sell a fixed maturity security. The types of events that may result in a sale include significant changes in the economic facts and circumstances related to the invested asset, significant unforeseen changes in liquidity needs, or changes in the Company's investment strategy.

The following table presents the fair value and gross unrealized losses for fixed maturity securities in an unrealized loss position as of March 31, 2025 and December 31, 2024, respectively. The Company views the decrease in fair value of all of the fixed maturity securities with unrealized losses as of March 31, 2025 as due to factors other than a credit loss. As of March 31, 2025, the Company has not made the decision to sell and it is not more likely than not the Company will be required to sell the fixed maturity securities with unrealized losses before a recovery of the amortized cost basis. In reaching our conclusion that an allowance for credit is unnecessary, we considered the factors described in the evaluation of credit loss impairments for fixed maturity securities critical accounting estimate in our Annual Report on Form 10-K. In the current three months ended March 31, 2025, the performance of fixed maturity securities has been impacted by the change in interest rates, specifically interest rates being at relatively high levels compared to interest rates at the time of acquisition of the securities. In consideration of the factors, we expect to receive cash flows sufficient to recover the entire amortized cost basis of the securities in the following table.

With regards to fixed maturity securities that had gross unrealized losses more than 12 months, the number of positions by their respective credit ratings were as follows:


	Number of Positions
	March 31, 2025	December 31, 2024
Credit Rating
AAA	154	155
AA	888	899

B	15	18
CCC or lower	6	4
Total below investment grade	62	62
Not rated	55	56
Totals:	1,828	1,862

Fixed maturity securities with an investment grade rating represented 98.1% of the gross unrealized losses as of March 31, 2025. For the same reasons discussed above, we expect to receive cash flow sufficient to recover the entire amortized cost basis of the securities in the previous table.

Maturities of Fixed Maturity Securities

The following table presents the distribution of the Company’s fixed maturity securities portfolio by estimated expected maturity. Estimated expected maturities differ from contractual maturities, reflecting assumptions regarding borrowers' utilization of the right to call or prepay obligations with or without call or prepayment penalties. For structured securities, estimated expected maturities consider broker-dealer survey prepayment assumptions and are verified for consistency with the interest rate and economic environments.

Limited Partnership Interests

Investments in limited partnership interests are predominately accounted for using the equity method of accounting (EMA) and include interests in commercial mortgage loan funds, real estate equity funds, private equity funds, infrastructure equity funds, infrastructure debt funds and other funds. In addition, we have two limited partnership investments accounted for at fair value using the fair value option (FVO). Principal factors influencing carrying amount appreciation or depreciation include operating performance, comparable public company earnings multiples, capitalization rates and the economic environment. The carrying amounts of EMA limited partnership interests were as follows:

Offsetting of Assets and Liabilities

The Company's derivatives are subject to enforceable master netting arrangements. Collateral support agreements associated with each master netting arrangement provides that the Company will receive or pledge financial collateral in the event minimum thresholds have been reached. The Company’s reverse repurchase agreements are also subject to enforceable master netting arrangements but there was no offsetting in their presentation in the Company’s Consolidated Balance Sheets. Information regarding the Company's derivatives is contained in Part II - Item 8, Note 4 in the Company's Annual Report on Form 10-K for the year ended December 31, 2024. The following table presents instruments that were subject to a master netting arrangement for the Company.

Reverse Repurchase Agreements

In connection with reverse repurchase agreements, the Company transfers primarily U.S. government, government agency and corporate securities and receives cash. For reverse repurchase agreements, the Company receives cash in an amount equal to at least 95% of the fair value of the securities transferred, and the agreements with third parties contain contractual provisions to allow for additional collateral to be obtained when necessary. The Company accounts for reverse repurchase agreements as secured borrowings. The securities transferred under reverse repurchase agreements are included in Fixed maturity securities with the obligation to repurchase those securities reported in Other liabilities on the Company's Consolidated Balance Sheets. The fair value of the securities transferred was $0.0 million as of March 31, 2025 and $12.4 million as of December 31, 2024. The obligation for securities sold under reverse repurchase agreements was a net amount of $0.0 million as of March 31, 2025 and $12.0 million as of December 31, 2024.

Deposits

As of March 31, 2025 and December 31, 2024, fixed maturity securities with a fair value of $26.1 million and $27.1 million were on deposit with governmental agencies as required by law in various states for which the insurance subsidiaries of HMEC conduct business. In addition, as of March 31, 2025 and December 31, 2024, fixed maturity securities with a fair value of $1,089.5 million and $1,072.2 million, respectively, were on deposit with the Federal Home Loan Bank of Chicago (FHLB) as collateral for amounts subject to funding agreements, advances and borrowings which were equal to $999.5 million as of March 31, 2025 and $989.5 million as of December 31, 2024. The deposited securities are reported as Fixed maturity securities on the Company’s Consolidated Balance Sheets.

Fair Value Disclosures [Abstract]

Fair Value of Financial Instruments

The Company is required to disclose estimated fair values for certain financial and nonfinancial assets and liabilities. Fair values for the Company’s insurance contracts other than annuity contracts (which are investment contracts) and equity method limited partnership interests are not required to be disclosed in fair value hierarchy. The estimated fair values of liabilities under all insurance contracts are taken into consideration in the Company’s overall management of interest rate risk through the matching of investment maturities with amounts due under insurance contracts.

Information regarding the three-level fair value hierarchy presented below and the valuation methodologies utilized by the Company to estimate fair values at each reporting date is included in Part II - Item 8, Note 3 of the

Consolidated Financial Statements in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024.

Financial Instruments Measured and Carried at Fair Value on a Recurring Basis

The following table presents the Company's fair value hierarchy for financial assets and financial liabilities measured and carried at fair value on a recurring basis. During the three months ended March 31, 2025 and 2024, there were no transfers between Level 1 and Level 2. As of March 31, 2025, Level 3 invested assets comprised 9.2% of the Company’s total investment portfolio at fair value.

(3)Transfers into and out of Level 3 during the three months ended March 31, 2025 and 2024 were related to changes in the primary pricing source or changes in observability of external information used in determining fair value. The Company's policy is to recognize transfers into and out of the levels as having occurred at the end of the reporting period in which the transfers were determined.

For the three months ended March 31, 2025, the Company had net gains of $5.8 million with respect to Level 3 financial assets. For the three months ended March 31, 2024, the Company had net gains of $0.1 million with respect to Level 3 financial assets. For the three months ended March 31, 2025 and 2024, a net investment loss of $1.9 million and $1.3 million, respectively, were included in net income that were attributable to changes in the fair value of Level 3 financial liabilities.

The valuation techniques and significant unobservable inputs used in the fair value measurement for financial assets and financial liabilities classified as Level 3 are subject to the processes as described in Part II - Item 8, Note 3 in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024. Generally, valuation techniques for corporate bonds include using discounted cash flow techniques where the unobservable input is the yield. The yield used for the valuation of these fixed maturity securities is less observable than securities classified as Level 2.

Financial Instruments Not Carried at Fair Value

The Company has various other financial assets and financial liabilities used in the normal course of business that are not carried at fair value, but for which fair value disclosure is required. These financial assets and financial liabilities are further described in Part II - Item 8, Note 3 in the Company's Annual Report on Form 10-K for the year ended December 31, 2024. The following table presents the carrying amount and fair value of the Company’s financial assets and financial liabilities not carried at fair value and the level within the fair value hierarchy at which such financial assets and liabilities are categorized.

Separate Account Liabilities

Separate account assets and liabilities consist of investment accounts established and maintained by the Company for certain variable contracts. Some of these variable contracts include minimum guarantees such as GMDBs that guarantee a minimum payment to the policyholder in the event of death.

The assets that support variable contracts are measured at fair value and are reported as separate account assets on the Consolidated Balance Sheets. An equivalent amount is reported as separate account liabilities. MRB assets and liabilities for minimum guarantees are valued and presented separately from separate account assets and separate account liabilities. MRBs are discussed further in the market risk benefits section of this Note to the Consolidated Financial Statements. Policy charges assessed against the policyholders for mortality,

administration and other services are included in the life premiums and contract charges line item on the Consolidated Statements of Operations and Comprehensive Income (Loss).

The following table presents the balances of and changes in the Separate Account variable annuity liabilities presented in the Consolidated Balance Sheets(1):


($ in millions)	Retirement Services

Reconciling item(1)	35.8		34.5
Total	$	349.2	$	347.2

(1) Reconciling item relates to DAC associated with the Property & Casualty reporting segment.

The assumptions used to amortize DAC were consistent with the assumptions used to estimate LFPB for traditional and limited-payment contracts. The underlying assumptions for DAC and LFPB were updated at the same time.

In the first quarter of 2025 and 2024, the Company conducted a review of all significant assumptions and did not make any changes to future assumptions because actual experience for mortality and lapses was materially consistent with underlying assumptions.

Reinsurance

Insurance [Abstract]

Reinsurance

The Company recognizes the cost of reinsurance premiums over the contract periods for such premiums in proportion to the insurance protection provided. Amounts recoverable from reinsurers for unpaid claims and claim settlement expenses, including estimated amounts for unsettled claims, claims incurred but not yet reported and policy benefits, are estimated in a manner consistent with the insurance liability associated with the policy. The effects of reinsurance on net premiums written and contract deposits; net premiums and contract charges earned; and benefits, claims and settlement expenses were as follows:


($ in millions)	Direct Amount		Ceded to Other Companies		Assumed from Other Companies		Net Amount










Three months ended March 31, 2025(1)
Net premiums written and contract deposits(2)	$	402.4	$	15.1	$	5.9	$	393.2
Net premiums and contract charges earned	306.7		14.4		6.0		298.3
Benefits, claims and settlement expenses	189.6		11.0		4.6		183.2

Three months ended March 31, 2024
Net premiums written and contract deposits(2)	$	386.4	$	18.1	$	7.3	$	375.6
Net premiums and contract charges earned	288.0		19.8		7.0		275.2
Benefits, claims and settlement expenses	186.9		14.6		4.0		176.3

(1) Direct amount is net of the annuity reinsurance transaction accounted for using the deposit method.

(2) This measure is not based on accounting principles generally accepted in the United States of America (non-GAAP). An explanation of this non-GAAP measure is contained in the Glossary of Selected Terms included as Exhibit 99.1 in the Company's reports filed with the SEC.

Segment Information

3 Months Ended

Segment Reporting [Abstract]

Segment Information

The Company conducts and manages its business through four reporting segments. The three reporting segments representing the major lines of business are: (1) Property & Casualty (primarily personal lines of auto and property insurance products), (2) Life & Retirement (primarily tax-qualified fixed and variable annuities as well as life insurance products), and (3) Supplemental & Group Benefits (primarily cancer, heart, hospital, supplemental disability, accident, short-term and long-term group disability, and group term life coverages). The Company does not allocate the impact of corporate-level transactions to these reporting segments, consistent with the basis for management's evaluation of the results of those reporting segments, but classifies those items in the fourth reporting segment, Corporate & Other. Corporate & Other includes corporate debt service, net investment gains (losses) and certain public company expenses, as well as corporate debt retirement costs, when applicable. In addition to these transactions, Corporate & Other also includes legacy commercial claims.

The accounting policies of the reporting segments are the same as those described in Note 1-Basis of Presentation and Significant Accounting Policies. Expense allocations are based on certain assumptions and estimates primarily related to direct cost, revenue and activity; methodologies are applied consistently. Stated segment operating results would change if different methods were applied.

The Company’s Chief Operating Officer is the chief operating decision maker (CODM), responsible for reviewing financial performance and making decisions regarding the allocation of resources for the reporting segments. The Company measures and analyzes segment performance based on core earnings which differs from total income as presented in our consolidated statements of operations due to excluding the after-tax impact of net investment gains (losses), discontinued operations, the after-tax impact of goodwill and intangible asset impairments and the cumulative effect of changes in accounting principles when applicable. We believe core earnings is a better performance measure and indicator of the profitability and underlying trends in our business. The CODM considers actual-to-budget variances in core earnings on a monthly basis when making decisions about allocating capital and personnel to segments and evaluating product pricing.

Disaggregated financial information for these segments, as regularly provided to the CODM, is as follows:

Equity [Abstract]

Accumulated Other Comprehensive Income (Loss)

AOCI represents the accumulated change in shareholders’ equity from transactions and other events and circumstances from non-shareholder sources. For the Company, AOCI includes the after tax change in net unrealized investment gains (losses) on fixed maturity securities, the after tax change in net reserve remeasurements attributable to discount rates and the after tax change in net funded status of benefit plans for the periods as shown in the Consolidated Statements of Changes in Shareholders’ Equity. The following table reconciles these components.

Commitments and Contingencies Disclosure [Abstract]
Contingencies and Commitments	Contingencies and Commitments Lawsuits and Legal Proceedings Companies in the insurance industry have been subject to substantial litigation resulting from claims, disputes and other matters. For instance, they have faced expensive claims, including class action lawsuits, alleging, among other things, improper sales practices and improper claims settlement procedures. Negotiated settlements of certain such actions have had a material adverse effect on many insurance companies. At the time of issuance of this Interim Report on Form 10-Q, except as noted below, the Company does not have pending litigation from which there is a reasonable possibility of material loss. In 2023, the Horace Mann Insurance Company (HMIC) was named as a defendant in one lawsuit and received various demands for reimbursement and notices of claims related to legacy, long-tail commercial lines claims, including asbestos, environmental, and sexual molestation claims. It is alleged that HMIC reinsured certain commercial lines policies as a member of various insurance pooling arrangements in the late 1960s and early 1970s. The related policies were written prior to the 1975 acquisition of Horace Mann by INA discussed in Part I - Item 1 of the Annual Report on Form 10-K. HMEC’s available records indicate that on January 1, 1975, HMIC entered a quota share retrocession treaty with INA. It is the Company’s understanding that claims arising under these legacy policies were handled by various third parties pursuant to the terms of that treaty and its subsequent amendments entered into on behalf of HMIC. Ultimately, after amendments to the treaty and various corporate transactions involving the reinsurer, these obligations were assumed by companies that were affiliated with R&Q Reinsurance Company (R&Q). The matters noted above arose following the March 23, 2023, Order of Liquidation in Pennsylvania of R&Q. HMIC is defending itself against the pending litigation and is in the process of investigating and evaluating the other demands and claims notices under a complete reservation of rights. In addition, in order to preserve its rights, HMIC submitted a proof of claim in the pending R&Q liquidation proceeding. In the fourth quarter of 2024, the Company recorded $15.7 million, after-tax of costs related to these non-core legacy commercial liability policies in the Corporate & Other Segment. As noted above, these policies were issued as early as the 1960s and prior to the current ownership structure of the Company. Investment Commitments The Company has outstanding commitments to fund investments primarily in limited partnership interests. Such unfunded commitments were $442.0 million and $449.9 million as of March 31, 2025 and December 31, 2024, respectively.

Basis of Presentation and Significant Accounting Policies (Policies)	3 Months Ended
	Mar. 31, 2025
Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation The accompanying Consolidated Financial Statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP) and with the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and disclosures normally included in annual financial statements prepared in conformity with GAAP, but are not required for interim reporting purposes, have been omitted. These Consolidated Financial Statements and Notes thereto should be read in conjunction with the Consolidated Financial Statements and Notes thereto included in Part II - Item 8 of the Company's Annual Report on Form 10-K for the year ended December 31, 2024. The results of operations for the three months ended March 31, 2025 are not necessarily indicative of the results to be expected for the full year. The accompanying Consolidated Financial Statements and Notes thereto are unaudited and reflect all adjustments (generally consisting only of normal recurring accruals) which are, in the opinion of management, necessary for the fair presentation of the consolidated financial position, results of operations and cash flows for the interim periods. The Company's significant accounting policies are summarized in Part II - Item 8, Note 1 of the Consolidated Financial Statements in the Company's Annual Report on Form 10-K for the year ended December 31, 2024. The Company has reclassified the presentation of certain prior period information to conform to the current year's presentation.
Consolidation	Consolidation All intercompany transactions and balances between HMEC and its subsidiaries and affiliates have been eliminated.
Use of Estimates	Use of Estimates The preparation of consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the reporting date of the consolidated financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from these estimates. The most significant critical accounting estimates include valuation of hard-to-value fixed maturity securities, evaluation of credit loss impairments for fixed maturity securities, valuation of future policy benefit reserves, and valuation of liabilities for property and casualty unpaid claims and claim expense reserves.
Future Adoption of New Accounting Standards	Future Adoption of New Accounting Standards Improvements to Income Tax Disclosures In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. This update will improve the transparency of income tax disclosures by requiring (1) consistent categories and greater disaggregation of information in the rate reconciliation and (2) income taxes paid disaggregated by jurisdiction. It also includes certain other amendments to improve the effectiveness of income tax disclosures. This guidance will be effective for the Company for annual periods beginning after December 15, 2024 and interim periods beginning after December 15, 2025. Early adoption is permitted. The guidance will have no net impact on the Company's consolidated financial position, results of operations, or cash flows. Disaggregation of Income Statement Expenses In November 2024, the FASB issued ASU 2024-04, 03 Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses. This guidance will improve the disclosures regarding a public business entity’s expenses by requiring (1) disclosure of the amounts of (a) purchases of inventory, (b) employee compensation, (c) depreciation, (d) intangible asset amortization, and (e) depreciation, depletion, and amortization recognized as part of oil and gas-producing activities (or other amounts of depletion expense) included in each relevant expense caption, (2) inclusion of certain amounts that are already required to be disclosed under current generally accepted accounting principles (GAAP) in the same disclosure as the other disaggregation requirements, (3) disclosure of a qualitative description of the amounts remaining in relevant expense captions that are not separately disaggregated quantitatively and (4) disclosure of the total amount of selling expenses and, in annual reporting periods, an entity’s definition of selling expenses. The amendments in this guidance will be effective for the Company for annual periods beginning after December 15, 2026, and interim periods beginning after December 15, 2027. Early adoption is permitted. The guidance will have no net impact on the Company's consolidated financial position, results of operations, or cash flows.
