Argo Group Reports 2020 Fourth Quarter Results

Underlying Underwriting Results Continue to Improve; Well-Positioned in 2021

• Strategic Growth: Premium growth focused on strategic growth areas, including 7% increase in U.S. Operations during the fourth quarter and full year 2020.
• Rate Increases Continue: Rate change remains above 10% on average across Argo's business in the fourth quarter and continued to increase from recent periods.
• Underlying Margin Improvement: A combination of underwriting actions taken during 2020, better pricing, improved terms and expense progress are driving current accident year, ex-catastrophe underwriting margin expansion compared to 2019.

Argo Group International Holdings, Ltd. ARGO ("Argo" or the "Company") today announced financial results for the three months and year ended December 31, 2020. Argo reported a fourth quarter 2020 net loss attributable to common shareholders of $19.7 million or $(0.57) per diluted common share, compared to a net loss attributable to common shareholders of $103.3 million or $(3.01) per diluted common share for the 2019 fourth quarter. Operating loss in the fourth quarter of 2020 was $18.2 million or $(0.52) per diluted common share, compared to an operating loss of $73.9 million or $(2.15) per diluted common share for the 2019 fourth quarter.

"We are encouraged by the improved underlying margins of our business during the quarter, as well as the actions taken to create a more focused and efficient company," said Argo Chief Executive Officer Kevin J. Rehnberg.

"While heightened 2020 catastrophe and COVID-19 losses resulted in a disappointing financial outcome, we made significant progress on our strategic objectives and achieved meaningful growth in most of our top-performing businesses – including Argo Pro, Construction and Inland Marine. We expect a sustained positive growth trajectory and continued benefits from market conditions throughout 2021, with the capital to meet those opportunities."

• Gross written premium grew 0.7% to $717.6 million during the fourth quarter of 2020. Premium growth in U.S. Operations of 6.6% was due to growth in Professional and Property lines driven primarily by rate increases. This was partially offset by a 10.4% decline in International Operations where recent underwriting actions have resulted in decreases in both Specialty and Property lines. Pricing increases remained in the low double digits on average across Argo, with a wide range varying by business line.
• The current accident year (CAY), ex-catastrophe (ex-CAT) loss ratio for the 2020 fourth quarter of 58.5% compares to 65.7% in the prior year quarter, which reflects improvement in both U.S. and International Operations and is the result of recent re-underwriting actions and achieved rate increases earning through results.
• Net unfavorable reserve development, which for the fourth consecutive quarter was modest for the 2020 fourth quarter at $1.6 million, or 0.3 points compared with $76.5 million or 17.9 points in the prior year quarter.
• Total catastrophe losses were $51.0 million, of which $38.3 million was related to natural catastrophes and $12.7 million was related to the COVID-19 pandemic. Approximately half of the reported natural catastrophe losses were due to events that happened late in the third quarter.
• The expense ratio of 40.1% improved 2.2 points compared to the prior year quarter. Included in the fourth quarter of 2020 are approximately 3 points related to certain strategic initiatives that generated non-recurring expenses related to personnel costs, legal and professional fees associated with certain transactions, the cost of early exit from certain office facilities and severance costs primarily in our International Operations. These actions are part of our previously announced expense initiatives and are expected to create savings toward our expense objectives.
• The CAY ex-CAT combined ratio was 98.5% compared to 107.9% in the prior year quarter. The improvement in the CAY ex-CAT combined ratio was due to a lower CAY ex-CAT loss ratio that was driven by stronger pricing and lower loss activity in International Operations, while the expense ratio also improved.
• The combined ratio was 110.0% compared to 126.7% for the 2019 fourth quarter. The lower combined ratio was primarily driven by a better loss ratio and improving expense ratio.
• Net investment income of $33.7 million decreased 1.5% compared to the 2019 fourth quarter. Net investment income excluding alternatives decreased 30.3% to $23.5 million due primarily to lower interest rates and continuing portfolio de-risking actions, while alternative investments contributed a gain of $10.2 million in the fourth quarter of 2020. The strong performance from alternative investments included gains from both private equity and hedge fund investments.
• Net loss attributable to common shareholders was $19.7 million or $(0.57) per diluted common share, compared to a net loss attributable to common shareholders of $103.3 million or $(3.01) per diluted common share for the 2019 fourth quarter. The 2020 fourth quarter result included foreign currency exchange losses of $9.2 million and minimal other corporate expenses, while the prior year quarter included other corporate expenses of $25.9 million and a goodwill impairment charge of $15.6 million.
• Operating loss was $18.2 million or $(0.52) per diluted common share, compared to an operating loss of $73.9 million or $(2.15) per diluted common share for the 2019 fourth quarter. The primary driver of the reduced operating loss was a lower level of underwriting losses in the fourth quarter of 2020.

• In our U.S. Operations, gross written premiums increased 6.6% compared to the 2019 fourth quarter due to growth in Professional and Property lines, while premiums in Liability and Specialty lines were down modestly. Growth in the period reflected rate increases across most lines of business, which continued to be strong at approximately 10% on average. This was partially offset by certain business units being impacted by economic headwinds as a result of COVID-19, as well as re-underwriting actions in certain business units. Certain strategic growth areas that are benefiting from strong market conditions, such as Casualty and Professional lines, experienced premium growth above 20% during the 2020 fourth quarter.
• Net written premiums increased 14.8% and earned premiums were up 12.4% compared to the 2019 fourth quarter due to growth in gross written premiums in prior quarters and an adjustment to ceded premiums in the prior year quarter. Net written and earned premium growth was primarily attributed to Professional and Specialty lines.
• The loss ratio for the fourth quarter of 2020 was 66.4%, an improvement of 5.2 points compared to the prior year quarter. The lower loss ratio was driven by a 1.9 point improvement in the CAY ex-CAT loss ratio and an 8.5 point reduction in unfavorable prior accident year reserve development. Although the CAY ex-CAT loss ratio improved compared to the prior year quarter, the result in the fourth quarter of 2020 was impacted by a large loss from a property account that has been non-renewed and a large liability claim that added 3.0 points to the loss ratio.
• Net unfavorable prior-year reserve development in the current quarter declined to $2.9 million from $25.5 million in the prior year quarter. These were partially offset by a higher level of catastrophe losses which totaled 5.2 points compared to an immaterial amount in the prior year quarter. Catastrophe losses in the quarter were primarily related to U.S. windstorms that occurred during the third and fourth quarters, as well as U.S. wildfires.
• The expense ratio for the fourth quarter of 2020 was 32.9%, a 0.3 point improvement compared to the 2019 fourth quarter. The lower expense ratio reflects premium growth in excess of expense growth, partially offset by slightly higher acquisition expenses.

• In our International Operations, gross written premiums declined 10.4% in the fourth quarter of 2020, as growth in Liability lines was more than offset by a decrease in Specialty and Property lines. Rates increased across all lines of business with particular strength in Liability lines, with average rate increases above 15% during the quarter. Rate increases across International were partially offset by re-underwriting and reducing line sizes in certain business lines, as well as the economic impact of COVID-19 on some businesses.
• Net earned premium in the fourth quarter of 2020 increased 4.1% from the 2019 fourth quarter. The increase was primarily related to growth in Liability lines.
• The loss ratio for the fourth quarter of 2020 was 76.5%, an improvement of 23.8 points compared to the prior year quarter. The lower loss ratio was primarily due to a 17.0 point year-over-year improvement in the CAY ex-CAT loss ratio and 1.1 points of favorable reserve development compared to 26.3 points of unfavorable reserve development in the prior year quarter. Catastrophe losses totaled 22.6 points in the fourth quarter of 2020, attributed to natural catastrophes and losses related to COVID-19 related losses. The CAY ex-CAT loss ratio was 55.0% in the fourth quarter of 2020 compared to 72.0% in the prior year period. The improvement during the fourth quarter and full year 2020 was primarily due to the impact of recent re-underwriting actions and achieved rate increases earning through results. The result in the fourth quarter of 2019 was also impacted by a recalibration of the CAY ex-CAT loss ratio based on prior year reserve adjustments.
• The expense ratio for the fourth quarter of 2020 was 45.6%, which improved 3.2 points compared to the prior year quarter. The fourth quarter 2020 result included approximately 4 points related to severance and certain one-time expenses that are not expected to recur.

Balance Sheet:

• Book value per common share was $49.39 at December 31, 2020, compared to $49.63 at September 30, 2020. Including dividends paid, book value per common share was approximately unchanged relative to September 30, 2020.

The inclusion of a forward-looking statement herein should not be regarded as a representation by Argo that Argo's objectives will be achieved.

NON-GAAP FINANCIAL MEASURES
In presenting the Company's results, management has included and discussed in this press release certain non-generally accepted accounting principles ("non-GAAP") financial measures within the meaning of Regulation G as promulgated by the SEC. Management believes that these non-GAAP measures, which may be defined differently by other companies, better explain the Company's results of operations in a manner that allows for a more complete understanding of the underlying trends in the Company's business. However, these measures should not be viewed as a substitute for those determined in accordance with generally accepted accounting principles ("U.S. GAAP").

"Underwriting income" is an internal performance measure used in the management of the Company's operations and represents net amount earned from underwriting activities (net premium earned less underwriting expenses and claims incurred). Although this measure of profit (loss) does not replace net income (loss) computed in accordance with U.S. GAAP as a measure of profitability, management uses this measure of profit (loss) to focus our reporting segments on generating underwriting income. The Company presents Underwriting income as a measure that is commonly recognized as a standard of performance by investors, analysts, rating agencies and other users of its financial information.

"Current accident year (CAY) ex-CAT combined ratio" and the "Current accident year (CAY) ex-CAT loss ratio" are internal measures used by the management of the Company to evaluate the performance of its' underwriting activity and represents the net amount of underwriting income excluding catastrophe related charges (impacts to both premium and losses), the impact of changes to prior year loss reserves and other one-time items that would impact expenses or net earned premium. Although this measure does not replace the GAAP combined ratio it provides management with a view of the quality of earnings generated by underwriting activity for the current accident year.

"Operating income" is an internal performance measure used in the management of the Company's operations and represents after-tax (at an assumed effective tax rate of 15%) operating results excluding, as applicable, net realized investment gains or losses, net foreign exchange gain or loss, and other similar non-recurring items, as well as preferred share dividends. The Company excludes net realized investment gains or losses, net foreign exchange gain or loss, and other similar non-recurring items from the calculation of operating income because these amounts are influenced by and fluctuate in part, by market conditions that are outside of management's control. In addition to presenting net income determined in accordance with U.S. GAAP, the Company believes that showing operating income enables investors, analysts, rating agencies and other users of the Company's financial information to more easily analyze our results of operations and underlying business performance. Operating income should not be viewed as a substitute for U.S. GAAP net income.

"Annualized return on average common shareholders' equity" ("ROACE") is calculated using average common shareholders' equity. In calculating ROACE, the net income available to common shareholders for the period is multiplied by the number of periods in a calendar year to arrive at annualized net income available to common shareholders. The Company presents ROACE as a measure that is commonly recognized as a standard of performance by investors, analysts, rating agencies and other users of its financial information. "Annualized operating return on average common shareholders' equity" is calculated using operating income (as defined above and annualized in the manner described for net income (loss) available to common shareholders under ROACE above) and average common shareholders' equity.

The "percentage change in book value per common share" includes (by adding) the effects of cash dividends paid per common share to the calculated book value per common share for the current period. This adjusted amount is then compared to the prior period's book value per common share to determine the period over period change. The Company believes that including the dividends paid per common share allows users of its financial statements to more easily identify the impact of the changes in book value per common share from the perspective of investors.

Reconciliations of non-GAAP financial measures to their most directly comparable U.S. GAAP measures are included in the attached tables and footnotes.
