CAPITAL RETURNS 4 INVESTOR PRESENTATION What Is This Proxy Contest About? 4 After incumbent nominees have overseen significant value destruction during their tenures, should shareholders trust them to guide a complex strategic transformation for which their lack of industry experience makes them ill - suited? OR Would shareholders be better served by electing two new directors to provide fresh and independent perspectives, one of whom is one of the Company’s largest active shareholders and both of whom are industry experts with decades of experience?

INVESTOR PRESENTATION I. Executive Summary 5

CAPITAL RETURNS 6 INVESTOR PRESENTATION We believe this Board has made significant errors in judgment The Company’s strategic review process and purported “transformation” have failed to drive value We believe the Board would benefit from highly qualified directors with relevant experience and fresh perspectives ▪ Argo has underperformed peers and the applicable indices over relevant measurement periods and during the tenure of every incumbent director ▪ In our view, shareholders have suffered because of unforced errors in judgment, including a stubborn reluctance to sell far - flung, non - core assets, inadequate leadership succession planning, poor hiring decisions, lack of expense discipline and untimely and inadequate financial reporting ▪ A year ago, we approached the Board with our concerns and an offer to help; our advice was initially ignored ▪ By the time the Board acceded to our logic and announced a formal strategic review process in April 2022, more than $300 million in shareholder value had already been destroyed 1 ▪ The Board then delayed Argo’s annual meeting by more than six months without any valid rationale, denying shareholders a meaningful say in the announced “strategic review” ▪ Shareholders have seen little evidence of the “progress” 2 that this Board is now touting, other than a few piecemeal asset sales; meanwhile, another $600 million in shareholder value has been destroyed 3 ▪ We believe there is no reason to be optimistic about Argo’s prospects as an independent company ▪ Our candidates, Ron Bobman and Dave Michelson, are insurance industry experts with decades of experience successfully analyzing, investing in and operating insurance companies all over the world ▪ In contrast, Directors Bailey and Ramji are primarily technologists and lack industry expertise and, in our view, appear ill - suited to oversee a complex transformation or a sale process ▪ Directors Bailey and Ramji also lack sufficient skin in the game; directors appear to be doing the bare minimum to satisfy the Board’s stock ownership guidelines ▪ Our candidates, if elected, will work diligently with Argo’s incumbent directors and management team to drive value on behalf of all shareholders Executive Summary 6 1.

Data as of November 4, 2022. Start date for transformation based on initial Board refreshment in February 2020. ▪ Argo Group International Holdings Ltd. (“Argo”) is a specialty insurer founded in 1957 and headquartered in Pembroke, Bermuda ▪ Since approximately February 2020, Argo has been undergoing a strategic transformation into a pure - play, U.S. - focused specialty insurer, but a multitude of scandals, poor strategy overhauls and personnel shifts have caused more harm than good — Argo removed CEO Mark Watson after a shareholder campaign that brought damaging facts to light and an SEC investigation that highlighted inappropriate expenses in a gross abuse of power — The Company is now on its third CEO in three years, having replaced its CEO twice since Watson, and has appointed a new CFO and head of the Company’s U.S. insurance business, in addition to several other executive - level appointments — Argo has taken a piecemeal approach to strategic realignment, exiting its international businesses through over a dozen different transactions, while continuing to suffer losses ▪ Since Argo began its “transformation,” the stock has declined by 64% 4 Enterprise Value ($M) $1,344.5 Market Cap ($M) $846.8 Share Price $24.18 2023E Book Value per Share $36.22 2023E EPS $3.82 P/2023E Book Value per Share 0.7x P/2023E EPS 6.3x Employees (as of 12/31/21) 1,290 % of Gross Premiums Written 3

CAPITAL RETURNS 8 INVESTOR PRESENTATION Overview of Capital Returns ▪ Long/short equity fund founded by Ron Bobman in 2003 ▪ Insurance specialist with industry operating, acquisition and investing experience spanning 30+ years — Including eight years as corporate finance and insurance industry M&A executive for investor Sam Zell ▪ Patient, long - term investor with a typical investment horizon of multiple years ▪ History of successful investor advocacy in the insurance sector, including: — FBL Financial – Challenged corporate governance with respect to affiliated party transaction and executed successful proxy fight resulting in approximately 10% higher transaction sale price — Health Innovations – Successfully urged board to initiate strategic review and introduced private equity buyer in take private transaction at significant premium — Watford Holdings – Challenged corporate governance with respect to affiliated party transactions and initiated activist campaign resulting in sale of company at significant premium — Protective Insurance – Successfully urged Board to initiate strategic review and introduced financial advisor resulting in successful sale of company to Progressive Corp. at significant premium ▪ Significant, long - term Argo Group shareholder — Capital Returns continues to own approximately 1%, making it one of the Company’s largest shareholders among actively - managed funds — Owned Argo stock for years 8

CAPITAL RETURNS 9 INVESTOR PRESENTATION Shareholders Should Support Our Nominees 9 Argo’s Board Has Destroyed Value We Believe Our Nominees Will Drive Positive Change — The Company has underperformed its peers and the applicable indices over relevant measurement periods — In our view, the Board has exercised poor judgment in hastily appointing executive team members, including Kevin Rehnberg as CEO; Thomas Bradley, first as Chairman and then as CEO; and most recently Jessica Snyder as President of U.S. Insurance — Late financial reporting and an insistence upon an illogical business configuration provide further evidence of the Board and management team’s inability to exercise proper judgment and manage risk — As the Board and management team flail about in their protracted attempt to reposition the Company through piecemeal asset sales, shareholders have continued to lose money on their investment, and Argo remains deeply undervalued 1 + Ron Bobman and Dave Michelson have decades of experience as investors and executives in the insurance industry + Argo incumbents Bernard Bailey and Al - Noor Ramji, by contrast, are technologists who do not appear to have any meaningful experience in property and casualty insurance + We believe that substituting our two insurance industry experts for Bailey and Ramji is likely to enhance the quality and objectivity of the Board’s deliberations + If elected, Messrs. Bobman and Michelson will work diligently with Argo’s incumbent directors and executive management team to drive value on behalf of all shareholders 1. As of November 4, 2022, Argo trades at approximately 0.7x consensus estimates of projected 2023 book value per share and just 6. 3x consensus estimates of projected 2023 earnings per share, while its specialty insurance peers enjoy a median valuation of 2.6 x consensus estimates of projected 2023 book value per share and 14.6x consensus estimates of projected 2023 earnings per share, according to FactSet. “Specialty Insuranc e P eers” include: W.

CAPITAL RETURNS 16 INVESTOR PRESENTATION We Believe a Sale Is the Best Path Forward 16 ▪ Though the Board has begun a strategic review (seven months after we implored it to do so) we believe its approach is suboptimal — To date, the Board’s strategic review process has yielded little more than piecemeal sales of non - core assets — Meanwhile, the Company has lost over $950 million in value 1 ; we believe the Board’s protracted review is harming shareholders 1. Source: FactSet. Data from September 13, 2021, to November 4, 2022. In our view, the Board must prioritize a sale of the whole Company to achieve maximum value for shareholders ▪ In our view, the Board must prioritize a sale of the whole Company to achieve maximum value for shareholders — We believe there are numerous acquirers willing to pay a premium – buyers that could consolidate and improve Argo’s operations while providing significant additional capital to the Company’s leading U.S. specialty business — In the absence of a sale, we see no reason why the Company will not continue its current trajectory of value destruction

CAPITAL RETURNS 17 INVESTOR PRESENTATION We Believe Argo’s Underperformance and Low Valuation Have Known Causes 17 Argo’s business configuration was and remains suboptimal Poor succession planning and hiring Lack of expense discipline Non - compliance with SEC reporting obligations The Board has manipulated election machinery to disenfranchise shareholders and avoid accountability 1 5 4 3 2

CAPITAL RETURNS 21 INVESTOR PRESENTATION Capital Returns Warned the Board of the Company’s Suboptimal Business Configuration 21 ▪ In September 2021, Capital Returns sent a letter to the Argo Board of Directors urging the Company to immediately explore a sale of the entire Company; our advice went largely unheeded ▪ The Company initially pursued a piecemeal approach, seeking to sell two Lloyd’s of London syndicates, and an Italian and Brazilian operation — In our view, the dangers of such an approach were obvious, with the disclosed collapse of the Argo Italy sale and the prolonged strategic review of Lloyd’s Syndicate 1200, proving us correct ▪ Finally, in April 2022 – more than seven months after our first letter – the Company announced a formal strategic review process — At best, Argo waited too long to listen to shareholder input — At worst, the Board needed a shareholder to explain the illogic of the Company’s strategy “We believe Argo’s long - established and profitable U.S. specialty business , with more than $2 billion of gross written premiums, is extremely valuable and possesses significant growth opportunities. The outstanding performance of the U.S. specialty business is, however, being restricted by capital constraints and obstructed from view by Argo’s lackluster international business...” 1 1.

CAPITAL RETURNS 22 INVESTOR PRESENTATION Poor Succession Planning 22 ▪ Upon the resignation of former CEO Mark Watson, the Company had the opportunity to conduct a full search and bring in the highest - quality talent available to help correct the gross abuse of power and SEC violations for which Mr. Watson was responsible ▪ However, the Board’s “solution” was to appoint Kevin Rehnberg as Interim CEO before making his role permanent in February 2020 — As an internal promotion with no prior CEO experience, Mr. Rehnberg doubled down on the flawed strategy of the previous manag eme nt team — Mr. Rehnberg immediately appeared out - of - his - depth; at an investor conference attended by Capital Returns, Mr. Rehnberg struggle d to name even one line of business underwritten by the Lloyd’s Syndicate 1200 and was frequently lost for words — During Mr. Rehnberg’s tenure, the Company lost more than a third of its value even as Argo’s Specialty Insurance Peers enjoye d a 25% median return over the same time period ▪ The Board repeated the same mistake by replacing Mr. Rehnberg with Thomas Bradley who, like Mr. Rehnberg, has no prior experience leading a publicly traded insurance company as Chairman or CEO ▪ Furthermore, since he was named as CEO, the Board has allowed Mr. Bradley to continue in his position as Chair — In our view, the combined position of Chair and CEO should be earned through a demonstration of exceptional leadership, not simply given as a courtesy or due to a lack of alternatives — Our concerns regarding the concentration of authority in the hands of Mr. Bradley are exacerbated by the Board’s appointment of a Lead Independent Director (Bernard Bailey) with no meaningful insurance experience Source: Statutory insurance and SEC filings. 2 In our view, the Board must be held responsible for hiring underqualified leaders and allowing them to destroy value at Argo

CAPITAL RETURNS 23 INVESTOR PRESENTATION The Board’s Latest Hire Evidences a Lack of Diligence 23 ▪ The Company recently hired Jessica Snyder as President of Argo’s U.S. insurance operations — Ms. Snyder has a known, abysmal track record, including recent but limited professional experience at mutual insurers GuideOne and State Auto — These companies reported statutory underwriting losses and combined ratios in excess of 100% during each year of her tenure ▪ Other investors appear to share our view; on the first trading day following the announcement of Ms. Snyder’s appointment, Argo’s stock price declined ~10% 2 ▪ In our view, the Board has demonstrated poor judgment by approving the hiring of Ms. Snyder 1.

CAPITAL RETURNS 25 INVESTOR PRESENTATION ▪ One of the most basic requirements of a public company is filing its required financial reports on time so shareholders can be adequately informed ▪ In 2022, Argo failed to file its 10 - K on a timely basis for the second year in a row ▪ Argo was previously charged by the SEC with inadequate disclosure of perquisites during former CEO Mark Watson’s tenure 1 — The SEC order found that Mr. Watson’s perks were four times higher than what the Company disclosed in its proxy statements filed in 2015 through 2019 2 — Worryingly, the SEC found that the inaccuracies continued even after the Company was made aware of them 3 — Argo nominee Al - Noor Ramji served on the Board during the time of Argo’s alleged reporting failures ▪ The Company has taken unexpected charges and asset valuation write - downs, repeatedly added material amounts to its liability for loss reserves, and most recently paid Enstar $125 million to take liabilities off its books 4 , reflecting poorly on the integrity and reliability of prior period financial statements ▪ Given that the Board is ultimately responsible for ensuring the timely and accurate reporting of the Company’s financial statements , we find these issues highly troubling 1.

CAPITAL RETURNS 26 INVESTOR PRESENTATION Does Mr. Ramji Have Adequate Time to Ensure the Argo Proxy Is Accurate? 26 Source: Company filings and websites. ▪ With so many commitments, it appears Mr. Ramji may not have thoroughly reviewed this year’s proxy statement biography, which seems to have been hastily (and erroneously) edited and does not reflect when he left his Prudential role ▪ Mr. Ramji currently sits on the Boards of Tata Motors and Nation Media Group and is prominently featured on their websites and financial reports – however, both boards are omitted from his Argo biography ▪ Furthermore, Mr. Ramji had at least two outside public directorships in the last five years (Virtusa and EVRY ASA), both of which are mentioned in prior proxies but excluded from this year’s biography ▪ If the Company cannot file its 10 - Ks on time or ensure its directors adequately update their biographies, what other issues could it be hiding beneath the surface? Mr. Ramji’s Biography in Argo’s Proxy Is Riddled with Omissions Argo fails to disclose when Mr. Ramji left his role at Prudential 1 Mr. Ramji’s biography omits current directorships at Tata Motors and Nation Media Group 2 Mr. Ramji had at least two public directorships in the last five years (Virtusa and EVRY ASA), both of which are omitted 3 Tata Motors Nation Media Group Undisclosed Current Directorships: Virtusa Undisclosed Prior Directorships: EVRY ASA 4

CAPITAL RETURNS 31 INVESTOR PRESENTATION The Argo Board Lacks Skin in the Game 31 % of Ownership Requirement Needed to Reach Baseline Threshold 1 ▪ Argo’s Equity Ownership Guidelines require each non - employee director to hold equity having a value equal to or greater than 5x the annual retainer they received for service on the Board in the preceding year (i.e., $85,000 x 5, or $425,000 in total) or hold all after - tax vested shares earned in connection with their Board service until they meet such threshold ▪ However, other than Mr. Plants, none of Argo’s incumbent directors currently own enough shares to meet the Company’s baseline threshold and appear to be doing the bare minimum to comply with the ownership guidelines ▪ Despite having been on the Board for several years each, Dr. Bailey and Mr. Ramji only own about 40% of the shares they need to reach the Company’s ownership threshold and have never purchased shares of the Company directly 1.

CAPITAL RETURNS 34 INVESTOR PRESENTATION Argo’s Claims Are Misleading 34 Argo’s Misleading Claim THE TRUTH “Over the last four years, Argo has added five best - in - class C - suite executives to oversee its transformation and lead the Company in its next phase of growth as a U.S. specialty insurer.” 1 ▪ The Company’s new head of its U.S. insurance operations, Jessica Snyder, has an unbroken string of underwriting losses and combined ratios above 100% during each of the last seven - plus years of her tenure prior to joining Argo 2 ▪ Argo’s Board waited nearly two years to replace the former CFO who had overseen the Company’s inadequate financial reporting and enrichment of former CEO Mark Watson 3 ▪ The Company’s last CEO, Kevin Rehnberg, destroyed value during his tenure, even as Argo’s Specialty Insurance Peers enjoyed a 25% median return over the same time period ▪ Like Mr. Rehnberg, current CEO Thomas Bradley has no prior experience leading a publicly traded insurance company as Chairman or CEO. Yet, he was appointed Chairman in 2020 and CEO in 2022 to replace Mr. Rehnberg, and to this day retains his position as Chair, to fill a leadership void caused by the Board’s own lack of adequate succession planning “[T]he Board and management team have taken decisive actions to best position Argo for the future, whether operating as a standalone entity or as part of a larger platform.” 1 ▪ Capital Returns advised the Board to run a strategic review process in September 2021; the Board initially resisted our suggestion, only to accede to our logic after over $950 million in shareholder value had been destroyed during the delay . 4 In our view, the Board has been reactive, not “decisive” ▪ We believe Argo’s piecemeal approach to reposition the Company is overly complex and time - consuming, and it continues to destroy shareholder value; since the strategic review was announced in April, the Company’s market value has declined by over $600 million 5 1.

CAPITAL RETURNS 35 INVESTOR PRESENTATION Argo’s Claims Are Misleading (Continued) 35 1. Source: Argo Group International Holdings Letter to Shareholders dated October 31, 2022. 2. The Argo proxy does not indicate when Mr. Ramji left his job at Prudential and incorrectly states that he does not serve on a ny outside public Boards, even though he serves on the Boards of Tata Motors and Nation Media Group, and that he did not serve o n o ther public Boards in the last five years, even though he served on the Virtusa Board until early 2021. Argo’s Misleading Claim THE TRUTH “The Company’s directors up for re - election at the annual general meeting have… critical expertise needed to continue to oversee the Company’s strategy as a pure - play U.S. specialty insurer.” 1 ▪ Dr. Bailey and Mr. Ramji have no direct insurance industry experience; Dr. Bailey currently serves as the President of a private consulting company focused on corporate governance and strategy; Mr. Ramji is a technologist, rather than operator, with no evident experience in property and casualty insurance ▪ Their skill sets are of limited relevance to the Company’s most important task – conducting a comprehensive and objective evaluation of Argo’s strategy and all strategic alternatives to create value for shareholders “The Board has concerns regarding Mr. Michelson’s ability to commit the appropriate time to the Argo Board, given that he currently serves as a director or advisor to at least six other companies.” 1 ▪ Mr. Michelson currently serves on a single public company board; if elected to the Board of Argo, we are confident in his ability to properly allocate his time between two public directorships ▪ The other companies for which Mr. Michelson serves as an advisor (not a director, as the Company implies) are all privately held start - ups; none of these are operational roles that require significant time or attention ▪ Dr. Bailey consulted on an undisclosed number of clients while serving on the Argo Board and, until recently, on the Telos Board ▪ Mr. Ramji was a full - time executive while serving on three public company Boards, including the Argo Board 2

INVESTOR PRESENTATION IV. Conclusion 36

CAPITAL RETURNS 37 INVESTOR PRESENTATION The Time for Change Is Now 37 We Believe Argo Has Underperformed and That Further Change is Needed We Believe Our Nominees Are Better Qualified to Effect Change ▪ Argo has destroyed value and underperformed its peers and the applicable indices over relevant measurement periods ▪ This Board has had more than enough time to address the Company’s underperformance and, in our view, has unequivocally failed ▪ We believe the Board has made errors in judgment: failing to configure the business optimally, inadequately managing two leadership successions, approving the hiring of executives who are ill - suited to improve the business, failing to insist on expense discipline and failing to oversee timely and accurate financial reporting ▪ The Board’s protracted strategic review process continues without any real progress beyond piecemeal asset sales ▪ We see no signs that things will improve, nor do we see any reason that this Board and these nominees deserve our confidence ▪ Directors Bailey and Ramji have both served on the Argo Board for several years; they have had their opportunity to create value for shareholders, and they have failed to do so ▪ Director Bailey lacks meaningful industry experience and is ill - suited to be a director on this Board, let alone as Lead Independent Director overseeing a first - time public company CEO ▪ Argo director Ramji has overseen the greatest value destruction as the longest - standing member of the Board and lacks operational expertise to help oversee the complex transformation of a specialty insurance business ▪ Our candidates are decidedly different, and we believe they will enhance the overall Board with their relevant expertise, as experienced investors and skilled operators, and fresh perspectives ▪ Our candidates are committed to working constructively and collaboratively with the incumbent directors on behalf of all shareholders
