Vote on the BLUE proxy card FOR Voce’s Highly-Qualified Nominees and
FOR Its Proposals

SAN FRANCISCO–(BUSINESS WIRE)–Voce Capital Management LLC (“Voce”), the beneficial owner of
approximately 5.6% of the shares of Argo Group International Holdings,
Ltd. (NYSE: ARGO) (“Argo” or the “Company”), today issued a detailed
presentation, “Righting the Ship,” which outlines a specific, actionable
plan which Argo’s Board could pursue to unlock substantial shareholder
value creation at the Company through a series of immediate expense
reductions, compensation reforms, capital allocation improvements,
portfolio rationalizations and sweeping corporate governance
enhancements.

Voce’s full presentation is available at www.Argo-SOS.com.

Important highlights include the following:

Argo Has Significant Opportunities to Boost its
Substandard Return on Equity:

• Historically, Argo has failed to cover its cost of capital – meaning
  it is destroying shareholder value. In Voce’s view, expense reductions
  alone can allow Argo to earn a double digit return on equity (“ROE”) –
  significantly higher than its 10-year average ROE of 5.7%.
• A thorough review of Argo’s capital allocation and portfolio of
  businesses is also required, including a potential divestiture of its
  international business, exit of underperforming lines and potential
  capital return.
• Voce’s analysis suggests 110 bps of ROE opportunity from enhanced
  capital allocation and 220 bps from portfolio rationalization.
• Adding capital allocation and potential sale of the international
  business would allow Argo to achieve an ROE of over 13%.
• If acted upon by the Board, Voce’s ideas could result in a pro forma
  ROE as high as 13.5% which could result in a share price approximately
  75-90% above its unaffected stock price on February 1, 2019, prior to
  Voce’s involvement.

The Company Must Pursue Immediate, Substantial
Expense Reductions:

• Voce offers a blueprint for immediate, substantial expense reductions
  of $100 million that would boost Argo’s ROE by 460 bps.
• Normalizing Argo’s OUE to that of its peer average implies a $100
  million expense opportunity (half of which Voce has already
  identified).
• Argo’s corporate and other underwriting expenses substantially exceed
  peers and its purported expense reductions are illusory. Voce believes
  the Company has simply transferred costs from its underwriting
  business and buried them in its investment portfolio.
• Since 2014, invested assets have grown at 4% annually, while
  investment expenses have grown at 25% annually.
• Reducing Argo’s investment expenses in line with peers would yield $16
  million in savings.
• $20 million in additional cost savings could be achieved by reigning
  in corporate expenses, including corporate aircraft and housing,
  vanity sponsorships and CEO compensation.

Argo Desperately Needs a Culture of Respect,
not Disdain, for Shareholders:

• Argo’s handling of Voce’s questions about a potential penthouse
  apartment where CEO Mark E. Watson III lives while in New York City
  demonstrates the Company’s disregard for shareholders and lack of
  respect for honesty when engaging with investors.
• Argo initially insisted that “The Company did not build, nor have we
  ever had, a penthouse apartment above our New York offices.”
  (emphasis added).
• As has now been independently verified and publicly reported by a news
  outlet, Argo does indeed own a duplex “glass penthouse apartment” in
  New York City – it’s just that it is located a mere six blocks away
  from Argo’s Meatpacking District offices, at 177 Ninth Avenue,
  Penthouse E, New York City, 10011.¹
• The penthouse was purchased for $5.795 million in 2016, which
  corresponds to the initiation of Argo’s disclosure regarding
  unreimbursed personal use of New York housing that began with its 2017
  Proxy Statement regarding the 2016 period. Voce has also independently
  confirmed that it is used as Mr. Watson’s home when in New York City.
• The penthouse is in the Chelsea Enclave development, “an urban oasis
  in the heart of Chelsea neighborhood with luxury apartments that share
  an enclosed garden with the General Theological Seminary.”²
  The opulent duplex, with its “open views and beaming light from the
  continuous walls of glass pull you from the entry through to the large
  living room and dining room and out onto the 41 foot long terrace.”³
  The original 2016 property listing, including photographs, is
  available on www.Argo-SOS.com.
• The property was purchased by the same Argo subsidiary, AGI
  Properties, Inc. that bought the three luxury corporate apartments in
  Miami that Voce first uncovered in its April 24^th press
  release.⁴

Argo’s Shockingly Deficient Corporate
Governance Must be Revitalized:

• Argo’s Board has, in Voce’s view, abjectly failed to adequately
  oversee CEO Watson and rein in his rampant use of corporate resources
  to fund his personal pursuits, from fine art, to architecture, to race
  cars, to yachting.
• In its presentation, Voce outlines how Argo’s G-5 corporate jet is
  used frequently for personal reasons – such as a Watson family
  Christmas holiday vacation to India in 2017, which the presentation
  outlines by matching flight logs to Mr. Watson’s hyperactive social
  media presence, including time and geo-stamped family photos he posted
  on Twitter.
• Voce believes a top-to-bottom investigation of Argo’s corporate
  governance practices is urgently required. This should take the form
  of an immediate investigation into expenses, compensation and
  corporate perquisites by a credible external law firm and overseen by
  a special committee of independent Directors.
• In Voce’s view, Argo’s Board suffers from docile, over-tenured
  directors who lack independence and whose interests are not aligned
  with those of all shareholders.
• The reconstitution of the Board and all committees and removal and
  replacement of the “Big 5” legacy directors – with nearly 20 years’
  average tenure – is urgently required.
• Argo’s flawed excessive executive compensation structure must be
  reformed, and the Board’s stale and ineffective Compensation Committee
  reconstituted.

Argo’s TSR – The Reality Behind the Numbers:

• Despite Argo’s attempts to deflect criticism by touting its total
  shareholder return (“TSR”), the Company’s TSR is not materially
  different from that of its peers. Even after its recent stock
  appreciation, Argo still trades near the bottom of its peer set
  because its ROE is also near the bottom. As a result, Argo’s
  historical discount to the multiple of its peers is persistent and
  ongoing.
• More than 100% of Argo’s recent stock returns have come from expansion
  of its P/BV multiple, while actual book value per share has shrunk
  over that period of time.
• Most of Argo’s P/BV expansion is due to speculation of M&A and Voce’s
  involvement (the stock has gained 18% since Voce’s 13D filing on
  February 4, 2019).

Voce issued the following statement in connection with the release of
“Righting the Ship”:

“As our presentation makes clear, there are abundant opportunities to
drive real value creation for all Argo shareholders – especially through
improving the Company’s poor ROE and reducing its expenses. Change is
needed now to achieve these goals.

We believe the five highly-qualified, fully-independent director
candidates we have nominated for election to Argo’s Board – Bernard C.
Bailey, Charles H. Dangelo, Admiral Kathleen M. Dussault, Carol A.
McFate and Nicholas C. Walsh – will restore accountability, independence
and integrity to the Company and drive substantial shareholder value
creation.

Unfortunately, as should be evident from the weeks of public discourse
and patent acts of entrenchment, Argo’s Board and leadership is plagued
by a pervasive culture of disdain for shareholders, disregard for norms
of basic corporate governance and a willingness to tolerate the
hijacking of corporate resources for the CEO’s pursuit of private
interests.

The case of Argo’s mysterious New York City luxury duplex penthouse
perfectly illustrates this. Argo should be ashamed of itself for issuing
such a sanctimonious and carefully hedged initial denial of the
penthouse’s existence given it now concedes, after all, that it does own
a swanky glass penthouse in New York. The point all along was not the location
of such corporate housing but rather its existence. While
Argo publicly stated multiple times that there was no penthouse above its
New York offices, it neglected to tell shareholders that it does owns a
penthouse apartment, within walking distance. This type of behavior
demonstrates a fundamental level of dishonesty.

We look forward to continuing to make our case to Argo shareholders in
the coming weeks as we approach this year’s Annual Meeting.”

The 2019 Annual Meeting is scheduled to be held on May 24, 2019. Voce
urges its fellow shareholders to vote on the Blue
proxy card FOR its highly-qualified nominees and FOR its proposals. For
