Risk factors and legal proceedings

The risks OCTAVE SPECIALTY GROUP INC names in Item 1A of its 10-K filed Mar 4, 2026: 42 risks under these headings, as written.4

  • Risks Related to OSG Common Shares
  • The price per share of OSG's common stock may be subject to a high degree of volatility, including significant price declines.
  • Risks Related to the Company's Business
  • We are subject to reputational harm if companies with which we do business engage in negligent or fraudulent behaviors and damage to our reputation could materially adversely impact our business.
  • Octave may be adversely impacted by P&C industry market cycles.
  • Catastrophic events may cause volatility of net income and comprehensive income primarily through changes to loss reserves, which may not be adequate to cover potential losses, and declines in revenues. Revenue may be adversely impacted by reduced business activity and lower sliding scale and profit commissions.
  • We could realize losses from our cash and investment accounts if one of the financial institutions we use fail or is taken over by regulators.
  • Our risk management policies and practices may not adequately identify significant risks.
  • We are subject to the risk of litigation and the outcome of proceedings we are or may become involved in could have a material adverse effect on our business, operations, financial position, profitability or cash flows.
  • Regulatory developments may materially adversely affect our business.
  • Our insurance subsidiaries are subject to minimum capital and surplus requirements, and our failure to meet these requirements could subject us to regulatory action.
  • Everspan may not be successful in executing its business plans or may experience greater than expected insurance underwriting losses and/or reinsurance counterparty losses, which could result in losses material to Everspan's capital position, a downgrade of its AM Best rating and a loss of its franchise value. Such events could have a material adverse impact on the value of OSG's shares.
The other 32 risks
  • A downgrade in the AM Best financial strength rating of Everspan may negatively affect our business.
  • Failure of Everspan's Program Partners to properly market, underwrite or administer policies could adversely affect us.
  • If, in our Specialty Property and Casualty Insurance business, we are unable to accurately underwrite risks and charge competitive yet profitable rates to our policyholders, our business, financial condition and results of operations may be adversely affected.
  • If Everspan is unable to obtain reinsurance coverage at reasonable prices or on terms that adequately protect it, we may be required to bear increased risks or reduce the level of our underwriting commitments.
  • Our insurance carriers are subject to reinsurance counterparty credit risk. Their reinsurers may not pay on losses in a timely fashion, or at all.
  • Everspan’s insurance carriers may be subject to counterparty credit risk associated with its MGA/U distribution partners.
  • If actual claims exceed loss and loss adjustment expense reserves for Everspan, or if changes in the estimated level of loss and loss adjustment expense reserves are necessary, including as a result of, among other things, changes in the legal/tort, regulatory and economic environments in which Everspan operates, our financial results could be materially and adversely affected.
  • Our ability to grow Everspan will depend in part on the addition of new Program Partners, and our ability to effectively onboard such new Program Partners could have an adverse effect on our business, financial condition and results of operations.
  • We compete with a large number of companies in the property and casualty insurance industry for underwriting premium.
  • We may be adversely affected by failures in services or products provided by third parties.
  • Impairment of intangible assets and goodwill could adversely affect our results of operations.
  • Our Insurance Distribution businesses derive a significant portion of their commission revenues from a limited number of insurance companies and Lloyd's syndicates, the loss of any of which could result in lower commissions or loss of business production.
  • Our Insurance Distribution businesses, results of operations, financial condition and liquidity may be materially adversely affected by certain potential claims or proceedings.
  • We may acquire additional MGA/Us as part of our Insurance Distribution business strategy. Risks associated with such endeavors could adversely affect our growth and results of operations.
  • Future growth of our Insurance Distribution business is highly dependent upon, amongst other items, our ability to launch de novo MGA/MGUs, which is highly dependent on our ability to attract insurance talent, operationalize new MGA/MGUs and compete for business.
  • Octave may not be able to realize expected synergies from acquisitions.
  • Octave is planning to further develop and expand its Specialty Property and Casualty Insurance and Insurance Distribution businesses; however, such plans may not be realized, or if realized, may not create value and may negatively impact our financial results.
  • Changes in law or in the functioning of the healthcare market could significantly impair our Accident & Health insurance business and therefore negatively impact Octave’s financial condition and results of operations.
  • Our Insurance Distribution businesses and their results of operations and financial condition may be adversely affected by conditions that result in reduced insurance capacity.
  • Variations in commission income that result from the timing of policy renewals and the net effect of new and lost business production may have unexpected effects on our results of operations.
  • Variations in contingent commissions that result from the effects of insurance loss activity on portfolios may result in significant variations in revenues.
  • Our P&C businesses rely on a limited number of retail and wholesale brokers to generate revenue and the loss of one or more of these key partners could adversely impact our results of operations and growth objectives.
  • System security risks, data protection breaches and cyber-attacks could adversely affect our business and results of operations.
  • The application of innovative and solution-based technology is required to facilitate effective operations and to realize internal efficiencies; however, the investment required in technology may not yield sufficient returns and the implementation of new or modified technology may be a material distraction to management.
  • Our ability to attract and retain qualified executives, senior managers and other employees or the loss of any of these personnel could negatively impact our business.
  • Our business could be affected by actions of stakeholders with differing interests or objectives.
  • We are exposed to foreign exchange risk, which may adversely affect our financial condition and results of operation.
  • Risks Related to Capital, Liquidity and Credit Markets
  • OSG and the Insurance Distribution business have outstanding indebtedness, resulting from the acquisition of ArmadaCorp on October 31, 2025, which could adversely affect our financial condition, operational flexibility and our ability to obtain financing in the future.
  • We may have future capital needs and may not be able to obtain third-party financing or raise additional third-party capital on acceptable terms, or at all.
  • Octave has significant obligations as the counterparty to several put contracts related to redeemable minority interests in our Insurance Distribution business. Obligations under these put contracts may be material and may require Octave to raise third party capital to fund.
  • Adverse economic factors, including recession, inflation, periods of high unemployment or lower economic activity could result in the sale of fewer policies than expected or an increase in the frequency or severity of claims and premium defaults or both, which, in turn, could affect our growth and profitability.
  • Changes in prevailing interest rate levels and market conditions could adversely impact our business results and prospects.
