Leading Independent Proxy Advisory Firms ISS and Glass Lewis Recommend that Argo Shareholders Vote “FOR” All Seven of Argo’s Highly Qualified Director Nominees

Argo’s Largest Shareholder, Voce Capital Management, Votes All its Shares in Support of Argo’s Director Nominees

The Argo Board of Directors Urges Shareholders to Vote “FOR” Argo’s Highly Qualified Director Nominees on the BLUE Proxy Card TODAY

HAMILTON, Bermuda--(BUSINESS WIRE)--Argo Group International Holdings, Ltd. (NYSE: ARGO) today announced that leading independent proxy advisory firms, Institutional Shareholder Services (ISS) and Glass Lewis & Co, have recommended that shareholders vote “FOR” all seven of Argo’s highly qualified director nominees at the Company’s upcoming Annual Meeting of Shareholders to be held on December 15, 2022.

In addition, Voce Capital Management LLC, the owner of approximately 9.5% of the Company’s common shares, has informed the Company that it has voted all of its shares on the BLUE proxy card in support of the seven Argo nominees at the Company’s upcoming 2022 annual meeting.

In making its recommendations, ISS stated in its December 2, 2022 report¹:

• “The dissident has not made a compelling case for change. The highest priority for ARGO is the ongoing strategic review. There is no reason to believe that the process is not being conducted to advance the best interests of shareholders, and there is no indication that a key competency or perspective is absent from the strategic review committee.”

• “The addition of Dan Plants in early August only bolstered the board's credibility, particularly because he was appointed to chair the strategic review committee.”

• “ARGO appears to have emerged from the tumult of 2019 with a more focused strategy. The company began closing and selling international and non-core units, and now draws over 95 percent of its revenue from the United States. This transition may have contributed to improved operations, as the revenue CAGR since the end of 2019 is almost double the claims and loss growth rate, even when the impact of the increase in loss reserves is taken into account.”

In making its recommendations, Glass Lewis stated in its December 2, 2022 report¹:

• “Overall, we recognize that steps taken by the incumbent board and management have significantly transformed Argo into a focused U.S. specialty commercial insurance business and the resulting company appears stronger, more efficient and better positioned to generate value for shareholders than the legacy structure, in our view.”

• “Shareholders should note that Capital Returns has not offered alternative suggestions to improve the business beyond pursuing a sale of the whole Company. Given that the board is already considering a sale and has solicited a large range of potential counterparties as part of the strategic review, we do not believe the Dissident Nominees would be clearly additive to the strategic review process or likely to improve the outcome for all shareholders, if appointed to the board.”

• “Furthermore, given the level of operational as well as board and management change that has already taken place at Argo over the last several years, we do not believe a further shakeup of the board would be a favorable development at this time.”

Argo issued the following statement:

We are pleased that ISS and Glass Lewis support the election of all seven of Argo’s director nominees. Both of these recommendations further validate our belief that Argo’s seven highly qualified nominees with relevant expertise and proven track records continue to move with speed to best position the Company.

The seven directors up for election at the annual general meeting – Bernard Bailey, Thomas Bradley, Dymphna Lehane, Samuel Liss, Carol McFate, J. Daniel Plants and Al-Noor Ramji – are integral to continuing Argo’s momentum, advancing our strategy and driving enhanced shareholder value.

This is a critical moment in Argo’s history. It is imperative that we continue the process we have underway to maximize value for shareholders.

To follow ISS’s and Glass Lewis’s recommendations, shareholders should vote “FOR” all seven of Argo’s highly qualified director nominees on the BLUE proxy card prior to the deadline of 9:00 a.m. local Bermuda time (8:00 a.m. Eastern Time) on December 13, 2022. Argo shareholders are advised to discard any white proxy cards they receive from Capital Returns. Argo shareholders can vote today by telephone, by internet or by signing, dating and returning the BLUE proxy card in the postage-paid envelope provided.
