Part I

Cincinnati Financial Corporation – Introduction

We are an Ohio corporation formed in 1968. Our lead subsidiary, The Cincinnati Insurance Company, was founded in 1950. Our main business is property casualty insurance marketed through independent insurance agencies in 46 states. Our headquarters is in Fairfield, Ohio.

Cincinnati Financial Corporation owns 100% of four subsidiaries: The Cincinnati Insurance Company (Cincinnati Insurance), Cincinnati Global Underwriting Ltd.SM (Cincinnati Global), CSU Producer Resources Inc. and CFC Investment Company. In addition, the parent company has an investment portfolio, owns the headquarters property and is responsible for corporate borrowings and shareholder dividends.

The Cincinnati Insurance Company owns 100% of four additional insurance subsidiaries. Our standard market property casualty insurance group includes two of those subsidiaries – The Cincinnati Casualty Company and The Cincinnati Indemnity Company. This group writes a broad range of business, homeowner and auto policies. The Cincinnati Insurance Company also conducts the business of our reinsurance assumed operations, known as Cincinnati Re®. Other subsidiaries of The Cincinnati Insurance Company include: The Cincinnati Life Insurance Company (Cincinnati Life), which provides life insurance policies and fixed annuities; and The Cincinnati Specialty Underwriters Insurance Company (Cincinnati Specialty Underwriters), which offers excess and surplus lines insurance products. In this report and elsewhere we often refer to any or all of these five companies as The Cincinnati Insurance Companies.

Cincinnati Global owns 100% of Cincinnati Global Underwriting Agency Ltd.SM, a London-based, global specialty underwriter for Lloyd's Syndicate 318, and Cincinnati Global Dedicated No. 2 Ltd.SM, a Lloyd’s corporate member and vehicle through which capital is provided by Cincinnati Financial Corporation and third-party names at Lloyd’s.

The two noninsurance subsidiaries of Cincinnati Financial Corporation are CSU Producer Resources, which offers insurance brokerage services to our independent agencies so their clients can access our excess and surplus lines insurance products; and CFC Investment Company, which offers commercial leasing and financing services to our agencies, their clients and other customers.

Our filings with the U.S. Securities and Exchange Commission (SEC) are available on our website,

investors.cinfin.com, as soon as possible after they have been filed with the SEC. Reports filed with the SEC may also be viewed at sec.gov. These filings include annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K and exhibits and amendments to those reports filed or furnished pursuant to Section 13(a) or 15(d) of the Securities Exchange Act of 1934. In this report we reference various websites. These websites, including our own, are not incorporated by reference in this Annual Report on Form 10-K.

Periodically, we refer to estimated industry data so that we can give information about our performance versus the overall U.S. insurance industry. Unless otherwise noted, the industry data is prepared by A.M. Best, a leading insurance industry statistical, analytical and insurer financial strength and credit rating organization. Information from A.M. Best is presented on a statutory accounting basis for insurance company regulation in the United States of America. When we provide our results on a comparable statutory accounting basis, we label it as such; all other company data is presented in accordance with accounting principles generally accepted in the United States of America (GAAP).

Our Business and Our Strategy

Introduction

The Cincinnati Insurance Company was founded by four independent insurance agents and 2025 marked 75 years in business. They established the mission that continues to guide all of the companies in the Cincinnati Financial Corporation family – to grow profitably and enhance the ability of local independent insurance agents to deliver quality financial protection to the people and businesses they serve by:

• providing insurance market stability through financial strength

• producing competitive, up-to-date products and services

• developing associates committed to superior service

At year-end 2025, a select group of independent agencies in 46 states actively marketed our property casualty insurance within their communities. Standard market and excess and surplus lines commercial policies were marketed in 44 of those states, with commercial E&S policies also available in California. Personal lines policies were marketed in 45 of those states. Within our select group of agencies, we also seek to become the life insurance carrier of choice and to help agents and their clients – our policyholders – by offering leasing and financing services.

Three competitive advantages distinguish our company, positioning us to build shareholder value and to be successful overall:

• Commitment to our professional independent insurance agencies and to their continued success

• Financial strength to fulfill our promises and be a consistent market for our agents’ business, supporting stability and confidence

• Operating structure that supports local decision making, showcasing our claims excellence and allowing us to balance growth with underwriting discipline

Management and our board of directors has developed an agency-focused strategy that we believe positions our company for long-term success and value creation, while managing difficult economic, market or pricing cycles. We broadly group our key strategic initiatives into two areas of focus – managing insurance profitability and driving premium growth, as summarized below. Our strategic priorities include meeting the wants and needs of our agent customers, attracting and developing talented associates, achieving best-in-class field service and continually enhancing operational efficiency and effectiveness. To help guide our strategic efforts, we have placed an emphasis on innovation to accelerate operational improvement and to also favorably position us for the future. We find innovative ideas in many places, including: internally through management and other associates, with our traditional business partners and in the start-up business community.

• Manage insurance profitability – Implementation of these initiatives is intended to enhance underwriting expertise and knowledge, thereby increasing our ability to manage our business while also gaining efficiency. We believe profit margins can be improved with additional information and expanded pricing capabilities we can access with the use of technology and analytics. This includes segmentation efforts that emphasize identification and retention of insurance policies we believe have relatively stronger pricing, while seeking more aggressive renewal terms and conditions on policies we believe have relatively weaker pricing. Pricing property casualty insurance policies includes estimates for expected losses, loss expenses to settle claims and expenses from underwriting policies while also considering the time value of money related to expected cash flows and a reasonable profit margin. In addition to enhancing company efficiency and more quickly deploying product or service enhancements, improving internal processes also supports the ability of the independent agencies that represent us to grow profitably by allowing them to serve clients faster and to more efficiently manage agency expenses as we make it easier for them to do business with us.

• Drive premium growth – Implementation of these initiatives is intended to further penetrate each market we serve through our appointed independent agencies. Strategies aimed at specific market opportunities, along with service enhancements, can help our agents grow and increase our share of

Our business involves various risks and uncertainties that may affect achievement of our business objectives. Many of the risks could have ramifications across our organization. For example, risks related to setting insurance rates and establishing and adjusting loss reserves could have an impact on our investment activities, growth and overall results if actual results differ from our assumptions, judgments or estimates in these areas.

The following discussion should be viewed as a starting point for understanding the significant risks we face. We organized the risks within each section to express the level of impact each could have on the company’s value. This ordering contemplates both the magnitude and probability of a particular risk. It is not a definitive summary of their potential impacts or of our strategies to manage and control the risks. See Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations, for a discussion of those strategies.

If any risks or uncertainties discussed here have or will develop into actual events, they could have a material adverse effect on our business, financial condition, results of operations or cash flows. The failure of our risk management strategies could also have a material adverse impact. In that case, the market price of our common stock could decline materially.

Readers should carefully consider this information together with the other information we have provided in this report, other reports and materials we file periodically with the Securities and Exchange Commission, news releases and other information we disseminate publicly.

Risks related to insurance operations

Loss reserves, our largest liability, are based on estimates and could be inadequate to cover actual losses.

Our consolidated financial statements are prepared using GAAP. These principles require us to make estimates and assumptions that affect the amounts reported in the Consolidated Financial Statements and accompanying Notes. Actual results could differ materially from those estimates. For a discussion of the significant accounting policies we use to prepare our financial statements, the material implications of uncertainties associated with the methods, assumptions and estimates underlying our critical accounting policies and the process used to determine our loss reserves, refer to Item 8, Note 1 of the Consolidated Financial Statements, and Item 7, Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves and Life Insurance Policy Reserves.

Our most critical accounting estimate is loss reserves. Loss reserves are estimates and are inherently uncertain; they do not and cannot represent an exact measure of liability. Inflationary scenarios, especially scenarios outside of historical norms, or regulatory changes that affect the assumptions underlying our critical accounting estimates, may make it more difficult to estimate loss reserves. Examples of inflation effects include adverse changes in the tort environment caused by more aggressive attorney involvement in insurance claims, increased litigation, expanded theories of liability, higher jury awards, lawsuit abuse and third-party litigation funding. Accordingly, our loss reserves for past periods could prove to be inadequate to cover our actual losses and related expenses. Any changes in these estimates are reflected in our results of operations during the period in which the changes are made. An increase in our loss reserves would decrease earnings, while a decrease in our loss reserves would increase earnings.

Unforeseen losses, or unintended coverages, the type and magnitude of which we cannot predict, may emerge. These additional losses could arise from changes in the legal environment, new or amended laws and regulations, climate change, catastrophic events, increases in loss severity or frequency, environmental claims, mass torts or other causes such as social inflation. Such future losses could be substantial. Elevated inflation in recent periods has significantly increased our loss costs in our auto and property businesses. It is possible that inflation could remain at high levels for a prolonged period or increase further, leading to additional increases in our loss costs. In addition, a significant portion of claims costs consists of medical costs. As a result, an increase in medical inflation could materially and adversely impact our loss costs and our loss reserves. Recent changes in the macroeconomic environment have impacted medical labor and materials costs, the potential persistency of which could result in future loss costs that are higher than our current expectations.

Our life policy reserves are also subject to uncertainty. Periods of higher death claims outside of long-term historical norms and not anticipated within our actuarial models could make our life policy reserves inadequate to cover actual future death claims. Increases in estimates of future death claims would increase life policy reserve levels and in turn decrease earnings.

Cincinnati Financial Corporation - 2025 10-K - Page 30

In addition to the risks stated above, Cincinnati Re reserves are subject to uncertainty because a reinsurer relies on the original underwriting decisions and claims reserving practices of ceding companies. As a result, we are subject to the risk that ceding companies may not have adequately evaluated the risks reinsured by us and the premiums ceded may not adequately compensate us for the risks we assume. In addition, there is generally a longer lapse of time from the occurrence of the event to the reporting of the loss or benefit to the reinsurer and ultimate resolution or settlement of the loss. Similar risks exist for Cincinnati Global due to potential delays in loss reporting.

Because of the inherent uncertainties involved in setting reserves, we cannot provide assurance that our existing reserves or future reserves will prove adequate in light of subsequent events. Our results of operations and financial condition have in the past been, and in the future could be, materially affected by adverse loss development for events that we insured in prior periods.

We could experience an unusually high level of losses due to natural or man-made catastrophe, terrorism or epidemic events or risk concentrations.

Our insurance operations expose us to claims arising out of catastrophes, which can be man-made or caused by natural perils in the U.S. or worldwide. Man-made catastrophes include, but are not limited to, industrial accidents, terrorist attacks, wars, cyberattacks, infrastructure failures, social unrest and riot. Other man-made events, such as hydraulic fracturing could cause damage from earth movement, while chemicals and other contaminants could create environmental and/or health hazards that in turn generate insurance losses. The geographic regions in which we market insurance and reinsurance are exposed to numerous natural catastrophes, such as:

• Hurricanes

• Earthquakes

• Landslides

• Severe convective storms, tornadoes, windstorms, hailstorms and flooding

• Wildfires

• Winter storms

On a worldwide basis, in the event of a severe catastrophic event or terrorist attack we may be exposed to material losses through our Cincinnati Re and Cincinnati Global operations. Due to the nature of these events, we are unable to precisely predict the frequency, severity or potential cost of catastrophe occurrences.

The extent of losses from a catastrophe is a function of both the total amount of insured and reinsured exposure in the area affected by the event and the severity of the event. Our ability to appropriately manage catastrophe risk depends partially on catastrophe models, which may be affected by inaccurate or incomplete data, the uncertainty of the frequency and severity of future events and the uncertain impact of climate change. Additionally, these models are recalibrated and changed over time, with more data availability and changing opinions regarding the effect of current or emerging loss patterns and conditions. See Item 7, Liquidity and Capital Resources, Modeled Catastrophe Loss Exposure, for a further discussion of the loss estimates derived from these models.

According to these models, probable maximum loss estimates from a single hurricane event that combines the effects of property casualty insurance written on a direct basis by The Cincinnati Insurance Companies, the Cincinnati Re reinsurance portfolio and risks insured by Cincinnati Global include the following amounts, net of amounts recoverable through reinsurance ceded and income taxes, and including the effects of estimated reinstatement premiums: $632 million for a once-in-a-100-year event and $987 million for a once-in-a-250-year event. See Item 7, Liquidity and Capital Resources, Modeled Catastrophe Loss Exposure, for a discussion of modeled losses considered in evaluating our risk mitigation strategy, which includes our ceded reinsurance program.

The occurrence of terrorist attacks in the geographic areas we serve could result in substantially higher claims under our insurance policies than we have anticipated. Some of our insurance policies provide coverage for terrorism risk in all areas we serve, including Tier 1 and Tier 2 cities. We have exposure to small co-op utilities, water utilities, wholesale fuel distributors, small shopping malls and small colleges throughout our 46 active states. Because of the number of associates located at our Fairfield, Ohio, headquarters, it is also exposed to terrorism risk. Additionally, our life insurance subsidiary could be adversely affected in the event of a terrorist event or an epidemic, particularly if the epidemic were to affect a broad range of the population or affect the overall economy.

Cincinnati Financial Corporation - 2025 10-K - Page 31

A catastrophe or epidemic event also could affect our operations by damaging our headquarters facility, injuring associates and visitors or disrupting our associates’ ability to perform their assigned tasks. Our associate health plan is self-funded and could similarly be affected.

Our results of operations would be adversely affected if the level of losses we experience over a period of time were to exceed our actuarially determined expectations. In addition, our financial condition may be adversely affected if we were required to sell securities prior to maturity or at unfavorable prices to pay an unusually high level of loss and loss expenses. Securities pricing might be even less favorable as a result of widespread losses and catastrophic events impacting a number of other companies and insurers. We also have been and may in the future be exposed to state guaranty fund assessments if other carriers in a state cannot meet their obligations to policyholders.

We market our standard market property casualty insurance products in 46 states, but our business is concentrated in the Midwest and Southeast, with a growing presence in California and New York. Our geographic concentration links our performance to business, economic, environmental and regulatory conditions in some states more than others. We also have exposure in states where we do not actively market insurance when clients of our independent agencies have businesses or properties in multiple states or we provide insurance through Cincinnati Global and reinsurance through Cincinnati Re.

Cincinnati Re and Cincinnati Global provide reinsurance or insurance coverage for property catastrophe events on a worldwide basis, including coverage for losses due to war, terrorism or political violence. Wars can occur anywhere, and our results of operations could be adversely affected, especially if effects of wars expand over time and space. We have limited direct exposure within our insurance operations to businesses or individuals in Russia, Ukraine or Gaza. We have exposure within our insurance operations, primarily through reinsurance treaties, to insured losses related to wars that include risks in the Middle East region. If hostilities expand in these regions or war breaks out in a new region, causing a high frequency of loss events, or a single extreme event, during the coverage period of our treaties or policies, our financial position and results of operations could be materially affected. Cincinnati Re is staffed with seasoned underwriting and analytical associates who strive to assume risks that we understand, both quantitatively and qualitatively, but given their global scope, a failure of their risk selection and modeling could materially affect our financial position and results of operations. We are also expanding Cincinnati Global, our global specialty underwriter with premiums primarily for U.S. and international property exposures. Cincinnati Global also writes North American and United Kingdom (U.K.) contingency and event cancellation coverage and worldwide credit and political risk coverage and political violence coverage. If there is a high frequency of large property catastrophe or terrorism events, or a single extreme event, during the coverage period of Cincinnati Global’s policies, our financial position and results of operations could be materially affected.

Climate change may adversely impact our results of operations and/or our financial position.

Scientists have linked global climate change from rising planet temperatures over the last several decades to a number of factors that contribute to the increased unpredictability, frequency, duration and severity of weather events. This includes changing weather patterns, a rise in ocean temperatures and sea level. Certain catastrophe models assume an increase in frequency and severity of certain weather or other events, which could result in a disproportionate impact on insurers with certain geographic concentrations of risk. Changes in climate and/or weather patterns may increase the frequency and/or intensity of severe weather and natural catastrophe events, including hurricanes, heavy precipitation events, heavy wind events, flash flooding, sea level rise, droughts, heat waves and wildfires potentially leading to increased insured losses. A continuation of these trends would also likely increase the risks of writing property insurance in coastal areas or areas susceptible to wildfires or flooding, or in areas susceptible to heavy wind events. The risk could be even greater in jurisdictions that restrict pricing and underwriting flexibility. We cannot predict how legal, regulatory or social responses to concerns about climate change may impact our business.

Our pricing and capital models could be flawed.

We use various actuarial pricing methods, predictive pricing and underwriting models, stochastic models and/or forecasting techniques to help us understand our business, analyze risk and estimate future trends. The output of these techniques and models assists us in making underwriting, pricing, reinsurance, reserving and capital decisions and helps us set our strategic direction. These models contain numerous assumptions, including the assumption that the data used is sufficient and accurate. They are also subject to uncertainties and limitations inherent in any statistical analysis. Actual results may be materially different from modeled output, resulting in pricing our products incorrectly, overestimating or underestimating reserves, or inaccurately forecasting the impact of modeled events on our results. This could materially adversely impact the results of our operations.

Cincinnati Financial Corporation - 2025 10-K - Page 32

Our ability to properly underwrite and price risks and increased competition could adversely affect our results.

Our financial condition, results of operations and cash flows depend on our ability to underwrite and set rates accurately for a full spectrum of risks. We establish our pricing based on assumptions about the level of losses that may occur within classes of business, geographic regions and other criteria.

To properly price our products, we must collect, properly analyze and use data to make decisions and take appropriate action; the data must be sufficient, reliable and accessible. We also need to develop appropriate rating methodologies and formulae; and we need to identify and respond to trends quickly. We may overestimate or underestimate loss cost trends or these trends may unexpectedly change – such as inflation in recent years outside of historical norms – leading to losing business by pricing risks above our competitors or charging rates too low to maintain profitability. Legal trends in recent years have also made it more difficult to determine adequate pricing, including adverse changes in the tort environment caused by more aggressive attorney involvement in insurance claims, increased litigation, expanded theories of liability, higher jury awards, lawsuit abuse and third-party litigation funding. If rates are not accurate, we may not generate enough premiums to offset losses and expenses, or we may not be competitive in the marketplace. Cincinnati Global has additional risks due to its reliance on coverholders in underwriting parts of its business.

Our ability to set appropriate rates are hampered if states where we write business refuse to allow rate increases that we believe are necessary to cover the risks insured. A state could also hamper our ability to set appropriate rates if it no longer allows us to use factors that we believe are predictive of loss, such as credit-based factors. Limitations on our ability to use various types of artificial intelligence (AI) in the development of pricing precision could adversely affect underwriting results. Multiple states require us to purchase reinsurance from a mandatory reinsurance fund. Such reinsurance funds can create a credit risk for insurers if not adequately funded by the state and, in some cases, the existence of a reinsurance fund could affect the prices charged for our policies. The effect of these and similar arrangements could reduce our profitability in any given period or limit our ability to grow our business.

The insurance industry is cyclical and competitive. From time to time, the industry goes through prolonged periods of intense competition during which it is more difficult to attract new business, retain existing business and maintain profitability. Competition in our insurance business is based on many factors, including:

• Competitiveness of premiums charged

• Relationships among carriers, agents, brokers and policyholders

• Underwriting and pricing methodologies

• Compensation provided to agents

• Underwriting discipline

• Terms and conditions of insurance coverage

• Speed with which products are brought to market

• Product and marketing innovations, including advertising

• Technological competence and innovation

• Ability to control expenses

• Quality of services and tools provided to agents and policyholders

• Claims satisfaction and reputation

We compete with major U.S., Bermudian, European, and other international insurers and reinsurers and with underwriting syndicates, some of which have greater financial, marketing and management resources than we do. Industry consolidation, including business combinations among insurance and other financial services companies, has resulted in larger competitors with even greater financial resources. We also compete with new companies that continue to enter the insurance and reinsurance markets. In addition, capital market participants have created alternative products that are intended to compete with Cincinnati Re's reinsurance products. Increased competition could result in fewer submissions, lower premium rates, and less favorable policy terms and conditions, which could reduce our underwriting margins and have a material adverse effect on our results of operations and financial condition.

Cincinnati Financial Corporation - 2025 10-K - Page 33

If our pricing were incorrect or we were unable to compete effectively because of one or more of these factors, our premium writings could decline and our results of operations and financial condition could be materially adversely affected. Large competitors could intentionally disrupt the market by targeting certain lines or underpricing the market. See the discussion of our Commercial Lines, Personal Lines, Excess and Surplus Lines and Life Insurance Segments in Item 1, Our Segments, for a discussion of our competitive position in the insurance marketplace.

We rely primarily on independent insurance agents to distribute our products.

We market our main products, insurance policies for businesses and individuals, through independent, nonexclusive insurance agents. These agents sell our competitors’ products and are not obligated to promote our products. We must offer insurance products that meet the needs of these agents and their clients. We need to maintain good relationships with the agents who market our products. If we do not, these agents may market our competitors’ products instead of ours. This could lead to a less desirable mix of business and affect our results of operations.

Certain events or conditions could diminish our agents’ desire to produce business for us and the competitive advantage that our independent agents enjoy, including:

• Downgrade of the financial strength ratings of our insurance subsidiaries.

• Concerns that doing business with us is difficult or not profitable, perceptions that our level of service is no longer a distinguishing characteristic in the marketplace, perceptions that our products do not meet the needs of our agents’ clients or perceptions that our business practices are not compatible with agents’ business models.

• Mergers and acquisitions of agencies could result in a concentration of a significant amount of premium in one agency or a small number of agencies.

• Delays in the development, implementation, performance and benefits of technology systems and enhancements or independent agent perceptions that our technology solutions do not match their needs.

Certain changes to our independent agency appointment strategy could affect our results of operations, including:

• A reduction in the number of independent agencies marketing our products.

• The failure of agencies to successfully market our products or pay amounts due to us,

• Changes in the strategy or operations of agencies or the choice of agencies to reduce their writings of our products.

• Inability to replace underperforming or nonperforming agencies with agencies that produce adequate and profitable premiums.

• A decline in the quality of independent agencies we are appointing.

Our ability to react to changes in consumer behavior and preferences.

The appeal of our value proposition could be affected by an unexpected change in the commoditization of insurance products. Policyholders may choose a competitor’s product rather than our own because of real or perceived differences in price, terms and conditions, coverage or service. If the quality of the independent agencies with which we do business were to decline, that also might cause policyholders to purchase their insurance through different agencies or channels. Consumers, especially in the personal insurance industry segment, may increasingly choose to purchase insurance from distribution channels other than independent insurance agents. Increased advertising by insurers, especially direct marketers, could cause consumers to shift their buying habits, bypassing independent agents altogether. Innovation, new or changing technologies and/or buying trends or consumer preferences could reduce or eliminate the need or demand for products we sell.

Economic downturns or other events have in the past and may in the future result in a softening of the insurance market and agents or consumers choosing a competitor’s product that may in turn adversely affect our premium revenues and underwriting profit. Such economic events experienced during recent periods included elevated inflation, global supply chain disruptions, implementation of tariffs, increasing interest rates, tightening credit markets and higher fuel costs.

Cincinnati Financial Corporation - 2025 10-K - Page 34

Our ability to obtain or collect on our reinsurance protection could affect our business, financial condition, results of operations or cash flows.

We buy property casualty and life reinsurance coverage to mitigate the liquidity risk and earnings volatility risk of an unexpected rise in claims severity or frequency from catastrophic events or a single large loss. The availability, amount and cost of reinsurance depend on market conditions and may vary significantly. If we were unable to obtain reinsurance on acceptable terms and in appropriate amounts, our business and financial condition could be adversely affected. Our reinsurers might experience significant losses, potentially jeopardizing their ability to pay losses we cede to them. It could also reduce the availability of reinsurance. If we cannot obtain adequate reinsurance or primary insurance coverage at a reasonable cost, it could constrain how much business we can write.

In addition, we are subject to credit risk with respect to our reinsurers. Although we purchase reinsurance to manage our risks and exposures to losses, this reinsurance does not discharge our direct obligations under the policies we write. We would remain liable to our policyholders even if we were unable to recover what we believe we are entitled to receive under our reinsurance contracts. Reinsurers might refuse or fail to pay losses that we cede to them, or they might delay payment. For long-tail claims, the creditworthiness of our reinsurers may change before we can recover amounts to which we are entitled. A reinsurer’s insolvency, inability or unwillingness to make payments under the terms of its reinsurance agreement with our insurance subsidiaries could have a material adverse effect on our financial position, results of operations or cash flows. See Item 7, Liquidity and Capital Resources, 2026 Reinsurance Ceded Programs, for a discussion of selected reinsurance transactions.

Our credit ratings or financial strength ratings of our insurance subsidiaries could be downgraded.

We believe our strong insurer financial strength ratings, in particular, the A+ (Superior) ratings from A.M. Best for our standard market property casualty insurance group and each subsidiary in that group, are an important competitive advantage. If our property casualty or life insurance subsidiary insurer financial strength ratings were to be downgraded, our agents might find it more difficult to market our products or might choose to emphasize the products of other carriers. Additionally, a downgrade in our ratings may adversely impact our Cincinnati Re operations by reducing our ability to market our reinsurance products or compete with other highly rated reinsurers. A downgrade in one or more of our company’s credit or debt ratings could adversely impact our borrowing costs or access to capital. Our ratings are subject to periodic review and there is no assurance that our ratings will not be changed. Rating agencies could change or expand their requirements or could find that our insurance subsidiaries no longer meet the criteria established for current ratings. See Item 1, Our Business and Our Strategy, Financial Strength, for additional discussion of our financial strength ratings.

International operations subject us to additional regulation and expose us to additional investment, political and economic risks.

International risks include restrictions such as price controls, capital controls, currency exchange limits, ownership limits and other restrictive or anti-competitive governmental actions or requirements, which could have an adverse effect on our business and reputation. Our business activities outside the U.S., including in the U.K., subject us to political and economic risks, including foreign currency and credit risk. Cincinnati Global in particular is subject to continued political and economic disruptions in the U.K. from its withdrawal from the European Union.

Business activities outside the U.S. subject us to additional domestic and foreign laws and regulations, including the Foreign Corrupt Practices Act, the U.K. Bribery Act and similar laws in other countries that prohibit the making of improper payments to foreign officials. In addition, insurers in the U.K. (including managing agents and members of Lloyd’s of London) are subject to Solvency II and the U.K. regulatory regime, which itself includes rules promulgated by Lloyd's. Although we have policies and controls in place that are designed to ensure compliance with these laws and regulatory requirements, if those controls are ineffective and an employee or intermediary fails to comply with applicable laws and regulations, we could suffer civil and criminal penalties and our business and reputation could be adversely affected. Some countries have laws and regulations that lack clarity and, even with local expertise and effective controls, it can be difficult to determine the exact requirements of, and potential liability under, the local laws. Failure to comply with local laws in a particular market may result in substantial liability and could have a significant and negative effect not only on our business in that market but also on our reputation generally.

Business activities at Cincinnati Global are subject to Lloyd's approval of a business plan each year. There is risk that Cincinnati Global's plan will not be approved or will be limited. As a Lloyd’s managing agent and syndicate, Cincinnati Global is exposed to various risks and their associated uncertainties, including Lloyd’s rating agency

ratings and reputation. Cincinnati Global also has an obligation to maintain funds at Lloyd’s to support its underwriting activities and periodic assessment of its capital, governance and other aspects of its business.

Risks related to investments or other financial matters

Financial disruption or a prolonged economic downturn could affect our investment performance.

Events, such as global supply chain disruptions, implementation of tariffs, an increasing interest rate environment and inflationary pressures, have contributed to significant disruption and volatility for financial markets and decreased economic activity. In the event that these conditions occur or continue, recur or result in a prolonged economic downturn or recession, they could materially and adversely impact our financial condition, results of operations or cash flows. These market conditions have in the past, and could in the future, cause our investment income or the value of securities we own to decrease. Additionally, the companies we invest in might be severely affected by a severe catastrophic event, terrorist attack, or epidemic event, which could in turn lower their stock value and affect our financial condition and results of operations.

Our ability to achieve our performance objectives could be affected by changes in the financial, credit and capital markets or the general economy.

We invest premiums received from policyholders and other available cash to generate investment income and capital appreciation, while also maintaining sufficient liquidity to pay covered claims and operating expenses, service our debt obligations and pay dividends. The value of our invested assets is an important component of shareholders’ equity or book value per share and changes in their valuation can have a significant impact. Changes in book value per share is a key performance objective as discussed in Item 7, Executive Summary of Management’s Discussion and Analysis.

For fixed-maturity investments such as bonds, which represented 58.5% of the fair value of our investment portfolio at the end of 2025, the inverse relationship between interest rates and bond prices leads to falling bond values during periods of increasing interest rates. Significant increases in the general level of interest rates, such as we experienced during recent periods, have an adverse effect on our shareholders’ equity.

Investment income is an important component of our revenues and net income. The ability to increase investment income and generate longer-term growth in book value is affected by factors beyond our control, such as: inflation, trade policy, economic growth, interest rates, world political conditions, changes in laws and regulations, future actions or inactions of the U.S. government, epidemic events, terrorism attacks or threats, war, adverse events affecting other companies in our industry or the industries in which we invest, market events leading to credit constriction, and other widespread unpredictable events. These events have in the past and may in the future adversely affect the economy generally and cause our investment income or the value of securities we own to decrease. Wars can occur anywhere in the world and have an adverse effect on our investment portfolio, especially if effects of wars expand over time and space. We do not have material exposure to investments based in Russia, Ukraine, Israel or Gaza. If there is significant expansion of wars beyond these regions, it may have adverse effects on our investment performance. Any significant decline in our investment income will have an adverse effect on our net income, and thereby on our shareholders’ equity and our statutory capital and surplus. For a more detailed discussion of risks associated with our investments, refer to Item 7A, Quantitative and Qualitative Disclosures About Market Risk.

We have issued universal life contracts with guaranteed minimum returns, referred to as bank-owned life insurance contracts (BOLIs). A BOLI is designed with the bank as the policy owner and the policy beneficiary. We legally segregate and record as separate accounts the assets and liabilities for certain BOLIs, when required by the specific contract provisions. Minimum investment returns, account values and death benefits are guaranteed by us for our separate account BOLIs. We could incur losses in the performance of these guarantees.

We also have life policy reserves established for traditional life policies including term, whole life and other products. Reserve variability can occur as reserves are based on certain cash flow assumptions as well as a discount rate assumption. Life policy reserves are required to be recorded using a discount rate assumption that is updated quarterly. As the discount rate increases during the quarter, life policy reserves decrease and accumulated other comprehensive income (AOCI) increases. Conversely, as the discount rate decreases during the quarter, life policy reserves increase and AOCI decreases. A significant decrease in discount rates, relative to the prior quarter, would have an adverse effect on shareholders' equity.

Cincinnati Financial Corporation - 2025 10-K - Page 36

Our investment performance also could suffer because of the types of investments, industry groups and/or individual securities in which we choose to invest. Market value changes related to these choices could cause a material change in our financial condition or results of operations.

Our investments in private equity, private credit, real property assets, private limited partnerships, and other alternative investments are subject to a higher level of illiquidity, economic volatility and real estate market deterioration. They lack quoted prices and active trade markets, and are subject to changing tax laws and an increased focus from the SEC and other regulators. These alternative investments have in the past, and may in the future result in reduced net investment returns, losses on sales of these investments, and/or the writing down the value of these investments, which would result in an adverse impact on operating results.

We also are exposed to credit risk related to guarantee and indemnification arrangements, which support our alternative investments and insurance operations. Our exposure to these guarantee and indemnification risks could materially and adversely affect our results of operations.

At year-end 2025, common stock holdings made up 40.0% of our investment portfolio. Adverse news or events affecting the global or U.S. economy or the equity markets, such as we experienced during recent years, will affect our net income, book value and overall results, and could affect our ability to pay our common stock dividend. See Item 7, Investments Results, and Item 7A, Quantitative and Qualitative Disclosures About Market Risk, for a discussion of our investment activities.

Deterioration in the banking sector or in banks with which we have relationships could affect our results of operations. Our ability to maintain or obtain short-term lines of credit could be affected if the banks from which we obtain these lines are acquired, fail or are otherwise negatively affected. We may lose premium revenue if a bank that owns appointed agencies were to change its strategies. We could experience increased losses in our director and officer liability line of business if claims were made against insured financial institutions.

A deterioration of credit and market conditions could also impair our ability to access credit markets and could affect existing or future lending arrangements. In addition, a failure to comply with covenants and other requirements under our credit facilities, senior debt and other debt obligations could have a material adverse effect on us and our ability to access the credit markets.

Our overall results are affected if a significant portion of our commercial lines or personal lines policyholders are adversely affected by marked or prolonged economic downturns and events such as a downturn in construction and related sectors, tightening credit markets and higher fuel costs experienced during recent periods. Such events make it more difficult for policyholders to finance new projects, complete projects or expand their businesses, and can lead to lower premiums from reduced payrolls and sales and lower purchases of equipment and vehicles. These events could also cause claims, including surety claims, to increase due to a policyholder’s inability to secure necessary financing to complete projects or to collect on underlying lines of credit in the claims process. Such economic downturns and events have a greater impact in the construction sector where we have a concentration of risks and in geographic areas that are hardest hit by economic downturns.

Deteriorating economic conditions could also increase the degree of credit risk associated with amounts due from independent agents who collect premiums for payment to us and could hamper our ability to recover amounts due from reinsurers.

Our status as an insurance holding company with no direct operations could affect our ability to pay dividends in the future.

Cincinnati Financial Corporation is a regulated holding company that transacts substantially all of its business through its subsidiaries. Our primary assets are the stock in our operating subsidiaries and our investments. Consequently, our cash flow to pay cash dividends and interest on our long-term debt depends on dividends we receive from our operating subsidiaries and income earned on investments held at the parent-company level.

Dividends received from our lead insurance subsidiary are restricted by the insurance laws of Ohio, its domiciliary state. These laws establish minimum solvency and liquidity thresholds and limits. Generally, the maximum dividend that may be paid is limited to the greater of 10% of statutory capital and surplus or 100% of statutory net income for the prior calendar year. Dividends exceeding these limitations may be paid only with prior approval of the Ohio Department of Insurance. Meanwhile, other subsidiaries are also limited in their payment of dividends to the lead

Cincinnati Financial Corporation - 2025 10-K - Page 37

insurance subsidiary under applicable insurance laws. We might not be able to receive dividends in the amounts necessary to meet our debt obligations or to pay dividends on our common stock without liquidating securities. See Item 1, Regulation, and Item 8, Note 9 of the Consolidated Financial Statements, for a discussion of insurance holding company dividend regulations.

General risk factors

The effects of changes in industry practices, laws and regulations on our business are uncertain.

As industry practices and legal, judicial, legislative, regulatory, political, social and other environmental conditions change, unexpected and unintended issues related to insurance pricing, claims and coverage emerge. There has been increased regulatory scrutiny of the use of machine learning and AI, and it is likely that we will be subject to new regulations that could materially adversely affect our operations or ability to write business profitably in one or more jurisdictions. These issues, and others, may adversely affect our business by impeding our ability to obtain adequate rates for covered risks or otherwise extending coverage beyond our underwriting intent, by increasing the number or size of claims, by varying assumptions underlying our critical accounting estimates or by increasing duties owed to policyholders beyond contractual obligations. In some instances, unforeseeable emerging and latent claim and coverage issues and court decisions or legislative changes may not become apparent until sometime after we have issued the insurance policies that could be affected by the changes. As a result, the full extent of liability under our insurance contracts may not be known for many years after a policy is issued and our pricing and reserve estimates may not accurately reflect its effect.

Some of our existing or potential shareholders, policyholders, associates, regulators, and other stakeholders will evaluate our business practices according to a variety of sustainability guidelines and expectations, including those related to climate change, inclusive diversity and equity, data privacy, and the well-being of our employees. Our business practices and disclosures are evaluated against sustainability guidelines, which are continually evolving and not always well defined or readily measurable today. Our practices may not change in the particular ways or at the rate stakeholders expect, leading to business or reputational challenges.

We are required to adopt new or revised accounting standards issued by recognized authoritative organizations, including the Financial Accounting Standards Board (FASB) and the SEC. Future changes required to be adopted could change the current accounting treatment that we apply and could result in material adverse effects on our results of operations, financial position or cash flows.

Our investment income benefits from tax rate preferences for municipal bond interest and dividend income from equity securities. Market valuations for these securities also benefit from the tax-preference aspect of current tax laws, affecting the value of our investment portfolio and also shareholders’ equity. Future changes in tax laws, or other changes such as regulations for applicability of alternative minimum taxes, could result in material adverse effects on our results of operations and financial condition.

The NAIC, state insurance regulators and state legislators continually re-examine existing laws and regulations governing insurance companies and insurance holding companies, specifically focusing on modifications to statutory accounting principles, interpretations of existing laws, regulations relating to product forms and pricing methodologies and the development of new laws and regulations that affect a variety of financial and nonfinancial components of our business. Any proposed or future legislation, regulation or NAIC initiatives, if adopted, may be more restrictive on our ability to conduct business than current regulatory requirements or may result in higher costs. The loss or significant restriction on the use of a particular variable, such as credit, in pricing and underwriting our products could lead to future unprofitability and increased costs.

Federal laws and regulations and the influence of international laws and regulations, including those that may be enacted in the wake of the financial and credit crises, may have adverse effects on our business, potentially including a change from a state-based system of regulation to a system of federal regulation, the repeal of the McCarran Ferguson Act, and/or measures under the Dodd-Frank Act that established the Federal Insurance Office and Financial Stability Oversight Council. The expansion of federal measures that change the scope of insurance and financial regulation may restrict our ability to conduct our insurance business, govern our corporate affairs or increase our cost of doing business.

In addition, climate change and climate change transitions may continue to lead to new or enhanced regulation, which may be difficult or costly to comply with, or impact assets that we invest in, which may result in realized and

Cincinnati Financial Corporation - 2025 10-K - Page 38

unrealized losses in future periods that could have a material adverse impact on our results of operations and/or financial position. It is not possible to foresee the impacts of potential future climate regulation, or which, if any, assets, industries or markets may be materially and adversely affected by global climate change and global climate change transitions, nor is it possible to foresee the magnitude of such effects. The effects of such changes could adversely affect our results of operations. See Item 7, Critical Accounting Estimates, Property Casualty Insurance Loss and Loss Expense Reserves and Life Insurance Policy Reserves, for a discussion of our reserving practices.

Elevated inflation negatively impacts profit and the value of investments.

Inflation in various forms, such as we experienced in recent periods, reduces underwriting profitability due to higher losses and loss expenses to repair damaged autos or other property that we insure. Inflationary volatility has and may in the future have an increased impact on us due to the three-year rates offered on some of our commercial lines policies. Elevated inflation can also be in the form of social inflation of litigation costs, jury awards and settlement expectations. In addition to adverse effects on the fair value of our equity portfolio, inflationary pressures can also cause or contribute to, or are the result of, increases in interest rates, which reduces the fair value of our fixed-maturity portfolio.

Managing technology initiatives and meeting data security requirements are significant challenges.

We use technology to process, store, retrieve, evaluate and use customer and company data and information. Our information technology and telecommunications systems, in turn, interface with and rely upon third-party systems. We must be able to access our systems to provide insurance quotes, process premium payments, make changes to existing policies, file and pay claims, provide customer support, manage our investment portfolios, report on financial results and perform other necessary business functions. Systems failures or outages could compromise our ability to perform these business functions in a timely manner, which could harm our ability to conduct business and hurt our relationships with our business partners and customers. In the event of a disaster such as a natural catastrophe, a pandemic, civil unrest, an industrial accident, a cyberattack, a blackout, a terrorist attack (including conventional, nuclear, biological, chemical or radiological) or war, systems upon which we rely may be inaccessible to our associates or independent agents for an extended period of time. Even if our associates and independent agents are able to report to work, they may be unable to perform their duties for an extended period of time if our data or systems used to conduct our business are disabled or destroyed. While technology can streamline many business processes and reduce the costs of operations, technology initiatives present short-term cost and also have implementation and operational risks. In addition, we may have inaccurate expense projections, implementation schedules or expectations regarding the effectiveness and user acceptance of the end product. These issues could escalate over time. If we were unable to find and retain associates with key technical knowledge, our ability to develop and deploy key technology solutions could be hampered.

Our systems have been, and will likely continue to be, subject to viruses or other malicious code, unauthorized access, cyberattacks, cyber frauds or other computer-related penetrations. Increasing sophistication of cyber criminals and terrorists make keeping up with new threats difficult and could result in a breach. Patching and other measures to protect existing systems and servers could be inadequate, especially on systems that are being retired. Controls employed by our U.S., off-shore and cloud vendors could prove inadequate. We could also experience a breach by intentional or negligent conduct on the part of associates or other internal or external sources. Independent agencies with access to our systems and servers expose us to additional cyber threats. Our systems and those of third-party vendors may become vulnerable to damage or disruption due to circumstances beyond our or their control, such as from catastrophic events, power anomalies or outages, natural disasters, network failures, viruses, ransomware and malware.

A breach of our security or the security of a vendor that results in unauthorized access to our data could expose us to a disruption or challenges relating to our daily operations as well as to data loss, litigation, damages, fines and penalties, significant increases in compliance costs and reputational damage. From time to time we have had to, and in the future we may need to, increase or expend resources to investigate or remediate vulnerabilities as a result of data security incidents. Such resources are costly in time and expense, and detract from resources spent on or are otherwise devoted to our core operations. In addition, depending on the nature of an incident, we may not be able to detect an incident readily, assess its severity or impact, or appropriately respond in a timely manner, which could increase our risk and exposures. See Item 1C, Cybersecurity, for further discussion of our cybersecurity risk management, strategy and governance.

Cincinnati Financial Corporation - 2025 10-K - Page 39

Any failure to protect the confidentiality of customer information could adversely affect our reputation or expose us to fines, penalties or litigation, which could impact our business, financial condition and results of operations.

We necessarily collect, use and hold data concerning individuals and businesses with whom we have a relationship. We are required to safeguard the confidential personal information of our customers and applicants. We are subject to an increasing number of federal, state, local and international laws and regulations regarding privacy and data security, as well as contractual commitments. These laws and regulations are rapidly evolving, complex, vary significantly among jurisdictions, and sometimes conflict. In the absence of updated, uniform federal privacy legislation, there is a growing trend in the states in which we operate, to adopt comprehensive privacy legislation that provides consumers with various privacy rights and imposes significant compliance burdens on covered companies. Failure to comply with data security or privacy laws or regulations could subject us to regulatory enforcement actions and fines, penalties, litigation, private rights of action or public statements against us by consumer advocacy groups or others if confidential customer information is misappropriated from our computer systems, those of our vendors, our independent agents or others with whom we do business, or otherwise. Despite the security measures that may be in place, any such systems may be vulnerable to the types of attacks and security incidents described above. Any well-publicized compromise of security could deter people from entering into transactions that involve transmitting confidential information, impart reputational or other harm, and/or have a material adverse effect on our business. Additionally, privacy legislation may make our business partners more reluctant to share information with us that is useful in conducting our business.

Our business depends on the uninterrupted operation of our facilities, systems, people and business functions.

Our business depends on our associates’ ability to perform necessary business functions, such as processing new and renewal policies and handling claims. We increasingly rely on technology and systems to accomplish these business functions in an efficient and uninterrupted fashion. Our inability to access our headquarters facilities for certain critical functions or a failure of technology, telecommunications or other systems or the loss or failure of services provided by key vendors, could significantly impair our ability to perform such functions on a timely basis or affect the accuracy of transactions. If sustained or repeated, such a business interruption or system failure could result in a deterioration of our ability to write and process new and renewal business, serve our agents and policyholders, pay claims in a timely manner, collect receivables or perform other necessary business functions. If our disaster recovery and business continuity plans did not sufficiently consider, address or reverse the circumstances of an interruption or failure, this could result in a materially adverse effect on our operating results and financial condition.

Our ability to successfully execute business functions also depends on hiring and retaining the qualified associates we employ. Competition for high-quality executives and other key associates occurs within the insurance industry and from other industries. We also must effectively develop and manage associates, including providing training and resources. Such tools and information can allow them to effectively perform critical business functions and adapt to changing business needs. During tight labor markets, such as we experienced in recent years, there is intense competition for associates qualified to execute important business functions. Many markets in which we operate are experiencing a low unemployment rate and labor shortages are affecting many industries. If we are unable to attract and retain certain associates, or if we fail to provide adequate training or resources, or fail to provide a work environment that is attractive to associates, we could limit the success of executing our strategic plans and vital business functions. Additionally, loss of key personnel or an inability to successfully execute on succession plans could negatively impact growth, operating results, financial condition, essential business relationships, profitability, and other business operations.

Risk Management and Strategy

As discussed further in Item 1, Regulation, Enterprise Risk Management, we manage cybersecurity as part of our overall enterprise risk programs.

As part of this program to keep our systems and data secure and to assist in understanding, assessing, identifying and managing material risks from cybersecurity threats, we take various measures through internal risk management efforts and testing by third-party experts. Those measures assess our cybersecurity program structure and capabilities and include blocking attempted cyber intrusions, defending against service disruptions, performing frequent vulnerability assessments and maintaining procedures to ensure timely notification of critical cybersecurity incidents and performance of related disclosure controls. We also have developed procedures and reporting processes when we identify an attempted cyber intrusion to the systems of one of our independent agents.

Additionally, the company uses third-party service providers, or vendors, in the course of conducting its operations. As such, the company has measures in place to help identify material risks from cybersecurity threats associated with the use of those vendors. When work with a vendor is evaluated, we consider, among other items, the availability of system and organization control reports, the use of artificial intelligence, interactions with our systems, the data involved and its level of sensitivity, the amount of data the vendor will process, where the data will be stored, how the data will be protected, what they will do with the data and destruction of data. Once a vendor is approved by the appropriate personnel, expectations regarding incident reporting are established and followed.

We are not aware of having experienced a material cybersecurity incident and we take commercially reasonable measures, described above and below, to monitor and respond to threats to keep our systems and data secure. However, we acknowledge that administrative, technical and internal accounting controls as well as other preventative actions may be insufficient to prevent security breaches to our systems or those of third parties with whom we do business due to, among other factors, changing technologies as well as criminal and state-sponsored cybercrime and cyber threats. Further, a material breach of our security or the security of a vendor that results in unauthorized access to our data could expose us to a disruption or challenges relating to our daily operations as well as to data loss, litigation, damages, fines and penalties, significant increases in compliance costs and reputational damage and could affect the company's strategy, results of operations or financial condition. See Item 1A, Risk Factors, for additional details.

Governance

Cybersecurity matters are an important part of reporting to our board of directors, executive management team, risk committee and disclosure committee. From a board perspective, the audit committee oversees the company's cybersecurity efforts along with additional oversight from the entire board. Two members of the audit committee have obtained certifications in cybersecurity oversight. Each quarter, the chief information officer and chief information security officer report to the audit committee on cybersecurity risks and controls. Also occurring each quarter, the entire board, and our senior executive team, as appropriate, receives a comprehensive report from the chief risk officer on the status and management of risk and other metrics relative to identified tolerances and limits, risk assessments and risk plans. Additionally, the chief risk officer has direct access to all members of the board of directors and presents in person at board meetings twice each year.

At the executive management and management levels, the chief information security officer leads the process of assessing and managing material risks from cybersecurity threats. Our chief information security officer has over 25 years of experience as a technology professional with in-depth knowledge of IT management processes and holds multiple degrees and professional designations, including as a certified information systems security professional (CISSP). The chief information security officer also works in collaboration with our chief information officer and chief risk officer and is supported by a cross-functional group of qualified and experienced professionals across various committees and functions. On a quarterly basis, the chief information officer provides a cybersecurity update to the disclosure committee and, on a monthly basis, the information security office team delivers a cybersecurity report to members of the senior executive team. Also refer to Item 10, Directors, Executive Officers and Corporate Governance, for additional qualification, experience and responsibility details.

Cincinnati Financial Corporation - 2025 10-K - Page 41

Associates involved in this area stay informed of industry trends and evolving threats using various resources including government authorities, peers, continuous education, industry publications, news outlets and other external parties that provide pertinent information. We take administrative, technical and internal accounting control measures to protect against cybersecurity incidents, including actions to monitor for, prevent, detect, mitigate and remediate any incidents that occur. These measures and actions include endpoint controls, multi-factor authentication and general cybersecurity education directed at our workforce and independent agents.

From a monitoring perspective, generally speaking, our information security office associates monitor the environment for threats, events and potential incidents. Depending on the potential severity of any identified incident, the company's incident response process, modeled after National Institute for Standards and Technology (NIST) frameworks, is initiated. As part of this process, each incident is evaluated and inventoried by our incident response team and reported to our legal compliance subcommittee for further action. Depending on severity, certain other internal and external parties may participate in the incident response process from a compliance and financial reporting perspective.

Incidents, regardless of severity, are evaluated and documented and are shared with the audit committee. In 2025, the audit committee received four updates on matters related to cybersecurity. The process of evaluating and documenting individual incidents, even when not deemed material, assists in determining how previous incidents have or may reasonably likely have a material effect on the company in the future.

Results of Operations

Introduction

The purpose of Management’s Discussion and Analysis is to provide an understanding of Cincinnati Financial Corporation’s consolidated results of operations and financial condition. Our Management’s Discussion and Analysis should be read in conjunction with Item 8, Consolidated Financial Statements and related Notes. We present per share data on a diluted basis unless otherwise noted, adjusting those amounts for all stock splits and stock dividends.

We begin with an executive summary of our results of operations, followed by other highlights and details about critical accounting estimates. In several instances, we refer to estimated industry data so that we can provide information on our performance within the context of the overall insurance industry. Unless otherwise noted, the industry data is prepared by A.M. Best, a leading insurance industry statistical, analytical and financial strength rating organization. Information from A.M. Best is presented on a statutory accounting basis for insurance company regulation in the United States of America. When we provide our results on a comparable statutory accounting basis, we label it as such; all other company data is presented in accordance with accounting principles generally accepted in the United States of America (GAAP).

Through The Cincinnati Insurance Company, Cincinnati Financial Corporation is one of the 25 largest property casualty insurers in the nation, based on net written premium volume for the first nine months of 2025, among more than 2,000 U.S. stock and mutual companies operating independently or in groups. We market our insurance products through a select group of independent insurance agencies in 46 states as discussed in Item 1, Our Business and Our Strategy.

The U.S. economy, the insurance industry and our company continue to face many challenges. Our long-term perspective has allowed us to address immediate challenges while also focusing on the major decisions that best position the company for success through all market cycles. We believe that this forward-looking view consistently benefits our shareholders, agents, policyholders and associates.

To measure our progress, we have defined a measure of value creation that we believe captures the contribution of our insurance operations, the success of our investment strategy and the importance we place on paying cash dividends to shareholders. We refer to this measure as our value creation ratio (VCR) and it is made up of two primary components: (1) our rate of growth in book value per share plus (2) the ratio of dividends declared per share to beginning book value per share. This measure, intended to be all-inclusive regarding changes in book value per share, uses originally reported book value per share in cases where book value per share has been adjusted, such as after the adoption of Accounting Standards Updates with a cumulative effect of a change in accounting.

The primary sources of our company’s net income are summarized below. We discuss contributions to net income and VCR by source in Corporate Financial Highlights, followed by more detailed discussion in Financial Results.

• Underwriting profit (loss) – Includes revenues from earned premiums for insurance and reinsurance policies or contracts, reduced by losses and loss expenses from associated insurance coverages. Those revenues are further reduced by underwriting expenses associated with marketing policies or related to administration of our insurance operations. The net result represents an underwriting profit when revenues exceed losses and expenses.

• Investment income – Is generated primarily from investing the premiums collected for insurance policies sold, until funds are needed to pay losses for insurance claims or other expenses. Interest income from bonds or dividend income from stocks are the main categories of our investment income, with additional contribution from compounding effects over time.

• Investment gains and losses – Occur from appreciation or depreciation of invested assets over time. Gains or losses are generally recognized from changes in market values of equity securities without a sale or when invested assets are sold or become impaired.

Executive Summary

Our value creation ratio, defined above, is our primary performance target. VCR trends are shown in the table below.

We are targeting an annual value creation ratio averaging 10% to 13% over the next five-year period. At 18.8% for 2025, our performance was above the high end of that range. We also exceeded the high end of the range for both the three-year and five-year periods that ended in December 2025.

The table below shows the primary contributors of our value creation ratio on a percentage basis. Analysis of the contributors aids understanding of our financial performance. Our financial results are further analyzed in the Corporate Financial Highlights section below.

The 2025 value creation ratio decreased by 1.0 percentage points, compared with 2024, and again included a significant contribution from operating results, as shown in the table above. The 2025 ratio decrease included 0.8 percentage points from net income before investment gains and 0.2 percentage points in overall net gains from our investment portfolio and other items. The increase in 2024, compared with 2023, was primarily due to an increase in operating results which was partially offset by a reduction in ove

Introduction

Market risk is the potential for a decrease in securities value resulting from broad yet uncontrollable forces such as inflation, economic growth, interest rates, world political conditions or other widespread unpredictable events. It is comprised of many individual risk categories that, when combined, create a macroeconomic impact. These risk categories include political, regulatory, economic and interest-rate risks. Company-specific risk is the potential for a particular issuer to experience a decline in value due to the impact of sector or market risk on the holding or because of issues specific to the firm. These risk categories include fraud, credit and default risks. The company accepts and manages risks in its investment portfolio as part of the means of achieving portfolio objectives.

The investment committee of the board of directors monitors the investment risk management process primarily through its executive oversight of our investment activities. We take an active approach to managing market and other investment risks, including the accountabilities and controls over these activities. Actively managing these market risks is integral to our operations and could require us to change the character of future investments purchased or sold or require us to shift the existing asset portfolios to manage exposure to market risk within acceptable ranges.

Sector risk is the potential for a negative impact on a particular industry due to its sensitivity to factors that make up market risk. Market risk affects general supply or demand factors for an industry and affects companies within that industry to varying degrees.

Fixed-Maturity Securities Investments

For both taxable and tax-exempt fixed-maturity securities, the inverse relationship between interest rates and bond prices leads to falling bond values during periods of increasing interest rates. We address this risk by attempting to construct a generally laddered maturity schedule that allows us to reinvest cash flows at prevailing rates. Although the potential for a worsening financial condition, and ultimately default, does exist with investment-grade corporate bonds, we address this risk by performing credit analysis and monitoring as well as maintaining a diverse portfolio of holdings.

As discussed in Item 1, Our Segments, Investments Segment, investment-grade fixed-maturity securities represented 97.5% of the portfolio. Further, of our $14.010 billion taxable fixed-maturity portfolio, $9.505 billion were investment-grade corporate securities with only $307 million being noninvestment-grade. For these noninvestment-grade holdings, the primary risk is credit risk. A weak financial profile can lead to rating downgrades from the credit rating agencies, which can put further downward pressure on bond prices. This puts more emphasis on the financial results achieved by the issuer rather than on general economic trends or statistics within the marketplace. We address this concern by analyzing issuer- and industry-specific financial results and by closely monitoring holdings within this asset class.

In addition to interest rate risk, the primary risk related to tax-exempt bonds is political risk associated with the specific environment within the boundaries of the issuing municipal entity. We address this concern by focusing on municipalities’ general-obligation debt and on essential-service bonds. Essential-service bonds derive a revenue stream from municipal services that are vital to the people living in the area (water service, sewer service, etc.). Another risk related to tax-exempt bonds is regulatory risk or the potential for legislative changes that would negate the benefit of owning tax-exempt bonds. We monitor regulatory activity for situations that may negatively affect current holdings and our ongoing strategy for investing in these securities.

A less significant risk is our exposure to credit risk for a portion of the tax-exempt portfolio that has support from corporate entities. Examples are bonds insured by corporate bond insurers or bonds with interest payments made by a corporate entity through a municipal conduit or authority. Our decisions regarding these investments primarily consider the underlying municipal situation. The existence of third-party insurance is intended to reduce risk in the event of default. In circumstances in which the municipality is unable to meet its obligations, risk would be increased if the insuring entity were experiencing financial duress. Because of our diverse exposure and selection of higher-rated entities with strong financial profiles, we do not believe this is a material concern as we discuss in Item 1, Our Segments, Investments Segment.

Interest Rate Sensitivity Analysis

Because of our strong shareholders’ equity, long-term investment horizon and ability to hold most fixed-maturity investments to maturity, we believe the company is well-positioned if interest rates were to rise. A higher rate environment would provide the opportunity to invest cash flow in higher-yielding securities, while reducing the likelihood of untimely redemptions of currently callable securities. While higher interest rates would be expected to increase the number of fixed-maturity holdings fair valued below 100% of amortized cost, we believe lower fixed-maturity security values due solely to interest rate changes would not signal a decline in credit quality.

Our dynamic financial planning model uses analytical tools to assess market risks. As part of this model, the effective duration of the fixed-maturity portfolio is continually monitored by our investment department to evaluate the theoretical impact of interest rate movements.

The table below summarizes the effect of an instantaneous hypothetical change in interest rates on the fair value of our fixed-maturity portfolio.

Cincinnati Financial Corporation - 2025 10-K - Page 110

The effective duration of the fixed-maturity portfolio was 5.6 years at year-end 2025, up from 5.0 years at year-end 2024. A 100-basis-point movement in interest rates would result in an approximately 5.9% change in the fair value of the fixed-maturity portfolio. Generally speaking, the higher a bond is rated, the more directly correlated movements in its fair value are to changes in the general level of interest rates, exclusive of call features. The fair values of average- to lower-rated corporate bonds are additionally influenced by the expansion or contraction of credit spreads.

In the dynamic financial planning model, the selected interest rate change of 100 to 200 basis points represents our views of a shift in rates that is quite possible over a one-year period. The rates modeled should not be considered a prediction of future events as interest rates may be much more volatile in the future. The analysis is not intended to provide a precise forecast of the effect of changes in rates on our results or financial condition, nor does it take into account any actions that we might take to reduce exposure to such risks.

Short-Term Investments

Our short-term investments consist of commercial paper purchased within one year of maturity. We make short-term investments primarily with funds to be used to make upcoming cash payments, such as dividends, taxes or other corporate purposes. At year-end 2025, we had $148 million of short-term investments compared with $298 million at year-end 2024.

Cincinnati Financial Corporation - 2025 10-K - Page 111

Equity Securities Investments

Our equity portfolio is subject to a variety of risk factors encompassed under the umbrella of market risk. General economic swings influence the performance of the underlying industries and companies within those industries. Industry- and company-specific risks also have the potential to substantially affect the value of our portfolio. Our investment guidelines help address these risks by diversifying the portfolio and establishing parameters to help manage exposures.

The table below summarizes the effect of hypothetical changes in market prices on the fair value of our equity portfolio.

Our equity holdings represented $12.694 billion in fair value at year-end 2025. No holding had a fair value greater than 7.8% of our $12.373 billion common stock portfolio. We had 44 holdings (among nine different sectors) each with a fair value greater than $100 million. See Item 1, Our Segments, Investments Segment and Item 8, Note 2 of the Consolidated Financial Statements, for additional details on our holdings.

The primary risks related to preferred stocks are similar to those related to investment-grade corporate bonds. Rising interest rates adversely affect market values due to the normal inverse relationship between interest rates and bond prices. Credit risk exists due to the subordinate position of preferred stocks in the capital structure. We minimize this risk by primarily purchasing investment-grade preferred stocks of issuers with a strong history of paying a common stock dividend.

Application of Asset Impairment Policy

As discussed in Item 7, Critical Accounting Estimates, Asset Impairment, our fixed-maturity investment portfolio is evaluated for credit-related impairments. The company’s asset impairment committee monitors a number of significant factors for indications of investments with a fair value below the carrying amount that may not be recoverable. During 2025 and 2024, no fixed maturity securities were written down to fair value, due to an intention to be sold. The application of our impairment policy resulted in write-downs of impaired securities intended to be sold that reduced our income before income taxes by $4 million in 2023. Impairments are discussed in Item 7, Investments Results.

We expect the number of fixed-maturity and short-term securities with a fair value below 100% of amortized cost to fluctuate as interest rates rise or fall and credit spreads expand or contract due to prevailing economic conditions. Further, amortized cost for some securities have been revised due to impairment charges recognized in prior periods. At year-end 2025, 2,597 of the 5,358 fixed-maturity and short-term securities we owned had a fair value below 100% of amortized cost compared with 3,723 of the 5,090 at year-end 2024 and 2,840 of the 4,738 at year-end 2023.

The 2,597 holdings fair valued below amortized cost at year-end 2025 represented 43.1% of our fixed-maturity and short-term investments portfolio and $397 million in unrealized losses.

• 1,974 of these holdings were fair valued between 90% and 100% of amortized cost. The value of these securities fluctuates primarily because of changes in interest rates. The fair value of these 1,974 securities was $6.734 billion at year-end 2025, and they accounted for $144 million in unrealized losses.

• 610 of these holdings were fair valued between 70% and 90% of amortized cost. The fair value of these holdings was $1.126 billion, and they accounted for $240 million in unrealized losses.

• 13 of these holdings had a fair value below 70% of amortized cost. The fair value of these holdings was $17 million, and they accounted for $13 million in unrealized losses.

The following table summarizes the length of time securities in the investment portfolio have been in a continuous unrealized loss position.

Responsibility for Financial Statements

We have prepared the consolidated financial statements of Cincinnati Financial Corporation and our subsidiaries for the year ended December 31, 2025, in accordance with accounting principles generally accepted in the United States of America (GAAP).

We are responsible for the integrity and objectivity of these financial statements. The amounts, presented on an accrual basis, reflect our best estimates and judgment. These statements are consistent in all material aspects with other financial information in the Annual Report on Form 10-K. Our accounting system and related internal controls are designed to assure that our books and records accurately reflect the company’s transactions in accordance with established policies and procedures as implemented by qualified personnel.

Our board of directors has established an audit committee of independent outside directors. We believe these directors are free from any relationships that could interfere with their independent judgment as audit committee members.

The audit committee meets periodically with management, our independent registered public accounting firm and our internal auditors to discuss how each is handling its respective responsibilities. The audit committee reports its findings to the board of directors. The audit committee recommends to the board the annual appointment of the independent registered public accounting firm. The audit committee reviews with this firm the scope of the audit assignment and the adequacy of internal controls and procedures.

Deloitte & Touche LLP, our independent registered public accounting firm, audited the consolidated financial statements of Cincinnati Financial Corporation and subsidiaries for the year ended December 31, 2025. Deloitte & Touche LLP met with our audit committee to discuss the results of its audit. They have the opportunity to discuss the adequacy of internal controls and the quality of financial reporting without management present.

Management’s Annual Report on Internal Control Over Financial Reporting

The management of Cincinnati Financial Corporation and its subsidiaries is responsible for establishing and maintaining adequate internal controls, designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with accounting principles generally accepted in the United States of America (GAAP). The company’s internal control over financial reporting includes those policies and procedures that:

• Pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;

• Provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP and that receipts and expenditures of the company are being made only in accordance with authorizations of management and the directors of the company; and

• Provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of the company’s assets that could have a material effect on the financial statements.

All internal control systems, no matter how well designed, have inherent limitations, including the possibility of human error and the circumvention of overriding controls. Accordingly, even effective internal control can provide only reasonable assurance with respect to financial statement preparation and presentation. Further, because of changes in conditions, the effectiveness of internal control may vary over time.

The company’s management assessed the effectiveness of the company’s internal control over financial reporting as of December 31, 2025, as required by Section 404 of the Sarbanes Oxley Act of 2002. Management’s assessment was based on the criteria established in the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and was designed to provide reasonable assurance that the company maintained effective internal control over financial reporting as of December 31, 2025. The assessment led management to conclude that, as of December 31, 2025, the company’s internal control over financial reporting was effective based on those criteria.

The company’s independent registered public accounting firm has issued an audit report on our internal control over financial reporting as of December 31, 2025.
