Disclosure Forward - Looking Statements This presentation contains forward - looking statements as that term is defined in the Private Securities Litigation Reform Act of 1995 . In some cases, such forward - looking statements may be identified by terms such as believe, expect, seek, may, will, intend, project, anticipate, plan, estimate, guidance or similar words . Forward - looking statements involve risks and uncertainties that could cause actual results to differ materially from those in the forward - looking statements . Although it is not possible to identify all of these risks and factors, they include, among others, the following : the inherent uncertainty of estimating reserves and the possibility that incurred losses may be greater than our loss and loss adjustment expense reserves ; inaccurate estimates and judgments in our risk management may expose us to greater risks than intended ; downgrades in the financial strength rating of our regulated insurance subsidiaries may impact our ability to attract and retain insurance and reinsurance business that our subsidiaries write, our competitive position, and our financial condition ; the potential loss of key members of our management team or key employees and our ability to attract and retain personnel ; adverse economic factors resulting in the sale of fewer policies than expected or an increase in the frequency or severity of claims, or both ; reliance on a select group of brokers and agents for a significant portion of our business and the impact of our potential failure to maintain such relationships ; reliance on a select group of customers for a significant portion of our business and the impact of our potential failure to maintain, or decision to terminate, such relationships ; our ability to obtain reinsurance coverage at prices and on terms that allow us to transfer risk and adequately protect our company against financial loss ; losses resulting from reinsurance counterparties failing to pay us on reinsurance claims, insurance companies with whom we have a fronting arrangement failing to pay us for claims, or a former customer with whom we have an indemnification arrangement failing to perform their reimbursement obligations ; inadequacy of premiums we charge to compensate us for our losses incurred ; changes in laws or government regulation, including tax or insurance law and regulations ; the ongoing effect of Public Law No . 115 - 97 , informally titled the Tax Cuts and Jobs Act, which may have a significant effect on us including, among other things, by potentially increasing our tax rate, as well as taxes on our shareholders ; in the event we do not qualify for the insurance company exception to the passive foreign investment company (“PFIC”) rules and are therefore considered a PFIC, there could be material adverse tax consequences to an investor that is subject to U . S . federal income taxation ; the Company or any of its foreign subsidiaries becoming subject to U . S . federal income taxation ; a failure of any of the loss limitations or exclusions we utilize to shield us from unanticipated financial losses or legal exposures, or other liabilities ; losses from catastrophic events, such as natural disasters and terrorist acts, which substantially exceed our expectations and/or exceed the amount of reinsurance we have purchased to protect us from such events ; the effects of the COVID - 19 pandemic and associated government actions on our operations and financial performance ; potential effects on our business of emerging claim and coverage issues ; exposure to credit risk, interest rate risk and other market risk in our investment portfolio ; the potential impact of internal or external fraud, operational errors, systems malfunctions or cyber security incidents ; our ability to manage our growth effectively ; failure to maintain effective internal controls in accordance with Sarbanes - Oxley Act of 2002 , as amended (“Sarbanes - Oxley”) ; and changes in our financial condition, regulations or other factors that may restrict our subsidiaries’ ability to pay us dividends . Additional information about these risks and uncertainties, as well as others that may cause actual results to differ materially from those in the forward - looking statements, is contained in our filings with the U . S . Securities and Exchange Commission ("SEC"), including our Annual Report on Form 10 - K filed with the SEC on February 26 , 2021 and our Quarterly Report on Form 10 - Q filed with the SEC on May 5 , 2021 . These forward - looking statements speak only as of the date of this release and the Company does not undertake any obligation to update or revise any forward - looking information to reflect changes in assumptions, the occurrence of unanticipated events, or otherwise . Non - GAAP Financial Measures This presentation contains non - GAAP financial measures as defined by Regulation G of the rules of the SEC . These non - GAAP measures, such as underwriting profit, adjusted net operating income, tangible equity and adjusted net operating return on average tangible equity (which is calculated as adjusted net operating income divided by the average tangible equity for the trailing five quarters) are not in accordance with, nor are they a substitute for, GAAP measures . We believe these non - GAAP measures provide users of our financial information useful insight into our performance . Investors should consider non - GAAP measures in addition to, and not as a substitute for, or superior to, the comparable GAAP measures . Please refer to pages 29 & 30 of this presentation for a reconciliation of the non - GAAP financial measures to the equivalent GAAP equivalents .

6 Commercial Auto Overview: Timeline • Recorded $170.0M in adverse development related to terminated commercial auto account • Meaningful change in actuarial methodologies using experience development methods only, giving more weight to incurred data • Surge in paid and incurred losses in Q4 2020 and Q1 2021 following delays in reporting due to COVID - 19 and higher severity • Most recent adverse development stems from accident years 2018 and 2019 • In Q 1 2021 , we continued to experience paid and incurred loss emergence which meaningfully exceeded expectations in our runoff large commercial auto account that we cancelled effective December 31 , 2019 • In response, we meaningfully adjusted our actuarial methodologies using our own loss experience in paid and incurred projections and giving greater weight to incurred methods, resulting in a significant strengthening of reserves ( $ 170 . 0 M pre - tax) • As noted, this account has been in run - off and has not produced any GWP since 2019 ( 1 ) • We believe this overhang has been eliminated, and that we are now fully able to focus on our prospective business and what continues to be a historically strong E&S market Commercial Auto Account Timeline Commercial auto represents 28% of consolidated GWP We delivered early notice of termination to the large account on 10/8/19 effective 12/31/19 following poor underwriting performance, changes to the risk and a desire to refocus on our Core E&S business We begin insuring rideshare business including one commercial auto account which grew significantly in later years Large account produced no premium; commercial auto represents 2 % of consolidated GWP (1) 2013 2019 2020 Large account produced no premium; commercial auto represents 2% of consolidated YTD GWP (1) 2021 (1) The large commercial auto account in runoff represents the bulk of our commercial auto gross written premiums. None of the remaining commercial auto business we write is exposed to the “ride - share” sector.

11 What is Driving Growth in the E&S Market? The E&S market began experiencing rate hardening in late 2018/early 2019 and the hardening significantly accelerated in 2020 driven by the Global Pandemic. Admitted market casualty pricing has not been keeping up with loss cost inflation for years. Admitted market carriers have thus been tightening underwriting guidelines or non - renewing business, pushing it to the E&S market Increasing jury verdicts and social inflation Reopening economy in the wake of a recession Increased risk of cyber threats as the world becomes more digitized Emergence of novel health risks Increasing catastrophe losses and risk of climate change (1) + (1) Please refer to our 10 - K filing for a detailed description of our reinsurance program. We believe we have little to no social inflation in our Core E&S book given its small account nature, client risk profile and limits deployment New business formation and small business revamp are our key clients We have negligible cyber exposure as an underwriter The overwhelming majority of our Core E&S book has an organic pathogen exclusion We write little cat exposed property, and for the risks we do insure we have robust reinsurance protection up to the 1:1,000 per year level (1)
