·Adjusted book value per share (excludes after-tax net unrealized investment gains) of $62.12, up 5% from year-end 2012. Book value per share of $66.65, down 1% due to the impact of the increase in interest rates on net unrealized investment gains.

New York, July 23, 2013 — The Travelers Companies, Inc. today reported net income of $925 million, or $2.41 per diluted share, for the quarter ended June 30, 2013, compared to $499 million, or $1.26 per diluted share, in the prior year quarter. Operating income in the current quarter was $816 million, or $2.13 per diluted share, compared to $495 million, or $1.26 per diluted share, in the prior year quarter. The increase in net and operating income compared to the prior year quarter primarily resulted from lower catastrophe losses, higher underlying underwriting margins (i.e., excluding net favorable prior year reserve development and catastrophe losses), and favorable tax and legal settlements, partially offset by lower net investment income and lower net favorable prior year reserve development. Net income also benefited from higher net realized investment gains.

“Results for the quarter were very strong, with net income of $925 million and return on equity of 14.6%,” commented Jay Fishman, Chairman and Chief Executive Officer.  “Operating return on equity was 14.2% for the quarter and 15.0% on a year-to-date basis, a significant improvement over prior year results primarily due to lower catastrophe losses and continued improvement in our underlying underwriting margins.

“We are very pleased with the pricing levels we achieved, which once again exceeded expected loss cost trends in all segments, while maintaining solid retentions.  Across our commercial insurance businesses, our ability to segment, price and select risk positions us well to continue to improve profitability.  In Personal Insurance, our strategy of seeking price increases and improved terms and conditions has improved profitability, but it has continued to negatively impact premiums.

“In June, we reached an agreement to acquire The Dominion of Canada General Insurance Company, part of our strategy of making targeted investments in attractive markets outside the United States. The Dominion will significantly improve Travelers’ market position and scale in Canada, and we are very enthusiastic about this opportunity.

“Given our focus on improving profitability, the underwriting results over recent quarters are gratifying. However, given the environment of low interest rates and volatile weather patterns, we will continue to seek higher margins. With improved returns as well as our strategy of returning excess capital to shareholders, we remain well positioned to deliver shareholder value,” concluded Mr. Fishman.

Second Quarter 2013 Results

(All comparisons vs. second quarter 2012, unless noted otherwise)

Net income of $925 million after-tax increased $426 million or 85% due to higher operating income and higher net realized investment gains after-tax. Operating income of $816 million after-tax increased $321 million or 65%, primarily reflecting improved underwriting results driven by lower catastrophes losses and higher underlying underwriting margins, as well as a $63 million benefit resulting from the resolution of prior year tax matters and a $59 million after-tax ($91 million pre-tax) gain from the settlement of a legal proceeding. These improvements were partially offset by lower net investment income and lower net favorable prior year reserve development.

Underwriting results

·The GAAP combined ratio improved 6.2 points to 94.3% due to lower catastrophes losses (3.9 points) and higher underlying underwriting margins (2.8 points), partially offset by lower net favorable prior year reserve development (0.5 points).

·Net favorable prior year reserve development occurred in all segments. Catastrophe losses resulted from wind and hail storms in several regions of the United States as well as flooding in Alberta, Canada.

·The underlying GAAP combined ratio improved 2.8 points to 91.7%, primarily resulting from earned rate increases exceeding loss cost trends in each segment.

Net investment income of $687 million decreased primarily due to lower reinvestment rates in the fixed income portfolio and lower private equity returns in the non-fixed income portfolio.

Net realized investment gains of $109 million after-tax ($167 million pre-tax) included an $87 million after-tax ($134 million pre-tax) gain related to a short position in U.S. Treasury futures contracts. The company closed this position by the end of the quarter.

Net written premiums of $5.824 billion decreased 1% as lower net written premiums in Personal Insurance were significantly offset by higher net written premiums in Business Insurance and Financial, Professional & International Insurance.

Year-to-Date 2013 Results

(All comparisons vs. year-to-date 2012, unless noted otherwise)

Net and operating income of $1.821 billion and $1.703 billion increased $516 million and $407 million, respectively, primarily reflecting the same factors discussed above for the second quarter.

Underwriting results

·The GAAP combined ratio improved 4.9 points to 91.4% due to higher underlying underwriting margins (3.3 points) and lower catastrophe losses (2.6 points), partially offset by lower net favorable prior year reserve development (1.0 point).

·Net favorable prior year reserve development occurred in all segments. Catastrophe losses included the second quarter 2013 events discussed above, as well as tornadoes and hail storms in the Southeastern United States in the first quarter 2013.

·The underlying GAAP combined ratio improved 3.3 points to 91.3%, primarily resulting from earned rate increases exceeding loss cost trends in each segment.

Net investment income decreased and net realized investment gains increased primarily reflecting the same factors discussed above for the second quarter.

Net written premiums of $11.421 billion were generally consistent with the prior year period as higher net written premiums in Business Insurance and Financial, Professional & International Insurance were offset by lower net written premiums in Personal Insurance.

Shareholders’ Equity

Shareholders’ equity of $24.890 billion decreased 3% from the end of first quarter 2013 and 2% from the end of the prior year primarily due to the impact of the increase in interest rates on net unrealized investment gains.  Included in shareholders’ equity were after-tax net unrealized investment gains of $1.692 billion, compared to $2.864 billion at the end of first quarter 2013 and $3.103 billion at the end of the prior year.  The company repurchased 3.6 million shares during the quarter and 7.3 million shares year-to-date under its existing share repurchase authorization at a total cost of $300 million and $600 million, respectively, leaving $1.559 billion of capacity under that authorization for future share

3

repurchases. Statutory surplus was $20.672 billion, and the ratio of debt-to-capital (excluding after-tax net unrealized investment gains) was 20.1%, well within its target range of 15% and 25%.

The Board of Directors declared a quarterly dividend of $0.50 per share. This dividend is payable September 30, 2013, to shareholders of record as of the close of business on September 10, 2013.

(All comparisons vs. second quarter 2012, unless noted otherwise)

Operating income of $154 million after-tax decreased $28 million or 15% primarily reflecting lower underwriting results driven by higher catastrophe losses and lower net favorable prior year reserve development, as well as lower net investment income. These declines were partially offset by higher underlying underwriting margins and a $15 million benefit resulting from the resolution of prior year tax matters.

·The underlying GAAP combined ratio improved 2.2 points to 89.9%, primarily resulting from earned rate increases exceeding loss trends, as well as a lower level of large losses within International, partially offset by an increase in the expense ratio driven by legal expenses related to the recently announced agreement to acquire The Dominion of Canada General Insurance Company and lower earned premiums.

Second Quarter 2013 Results

(All comparisons vs. second quarter 2012, unless noted otherwise)

Operating income of $142 million after-tax increased $125 million, primarily reflecting improved underwriting results driven by lower catastrophe losses and higher underlying underwriting margins, as well as a $5 million benefit resulting from the resolution of prior year tax matters.

·The underlying GAAP combined ratio improved 3.0 points to 90.0% primarily resulting from earned rate increases exceeding loss cost trends in both Automobile and Homeowners & Other, as well as lower non-catastrophe weather-related losses.

Personal Insurance net written premiums of $1.907 billion decreased 5% primarily due to lower new business volumes in both Automobile and Homeowners & Other, largely as a result of the company’s pricing strategy, increasing deductibles and other profitability improvement initiatives.

·during or following a period of financial market disruption or economic downturn, the company’s business could be materially and adversely affected;

·if actual claims exceed the company’s claims and claim adjustment expense reserves, or if changes in the estimated level of claims and claim adjustment expense reserves are necessary, the company’s financial results could be materially and adversely affected;

·the company’s investment portfolio may suffer reduced returns or material realized or unrealized losses;

9

·changes in federal regulation could impose significant burdens on the company and otherwise adversely impact its results;

·a downgrade in the company’s claims-paying and financial strength ratings could adversely impact the company’s business volumes, adversely impact the company’s ability to access the capital markets and increase the company’s borrowing costs;

·the inability of the company’s insurance subsidiaries to pay dividends to the company’s holding company in sufficient amounts would harm the company’s ability to meet its obligations, pay future shareholder dividends or make future share repurchases;

·disruptions to the company’s relationships with its independent agents and brokers could adversely affect the company;

·the company’s efforts to develop new products or expand in targeted markets may not be successful and may create enhanced risks;

·the company may be adversely affected if its pricing and capital models provide materially different indications than actual results;

·the company’s business success and profitability depend, in part, on effective information technology systems and on continuing to develop and implement improvements in technology;

·if the company experiences difficulties with technology, data security and/or outsourcing relationships, the company’s ability to conduct its business could be negatively impacted;

·the company’s businesses may be adversely affected if it is unable to hire and retain qualified employees;

·loss of or significant restriction on the use of credit scoring in the pricing and underwriting of Personal Insurance products could reduce the company’s future profitability;

·the company’s repurchase plans depend on a variety of factors, including the company’s financial position, earnings, share price, catastrophe losses, maintaining capital levels commensurate with the company’s desired ratings from independent rating agencies, funding of the company’s qualified pension plan, capital requirements of the company’s operating subsidiaries, legal requirements, regulatory constraints, other investment opportunities (including mergers and acquisitions and related financings), market conditions and other factors;

·the company may not achieve the anticipated benefits of its transactions or its strategic initiatives, including in Personal Insurance, or complete a transaction that is subject to closing conditions; and

·conditions in the capital markets may not be suitable for the company to incur additional indebtedness and/or to issue preferred stock to finance its merger and acquisition transactions, including the acquisition of The Dominion.

GLOSSARY OF FINANCIAL MEASURES AND RECONCILIATIONS OF NON-GAAP MEASURES TO GAAP MEASURES

The following measures are used by the company’s management to evaluate financial performance against historical results and establish targets on a consolidated basis. In some cases, these measures are considered non-GAAP financial measures under applicable SEC rules because they are not displayed as separate line items in the consolidated financial statements or are not required to be disclosed in the notes to financial statements or, in some cases, include or exclude

10

certain items not ordinarily included or excluded in the most comparable GAAP financial measure. Reconciliations of non-GAAP measures to their most directly comparable GAAP measures also follow.

In the opinion of the company’s management, a discussion of these measures provides investors, financial analysts, rating agencies and other financial statement users with a better understanding of the significant factors that comprise the company’s periodic results of operations and how management evaluates the company’s financial performance.  Internally, the company’s management uses these measures to evaluate performance against historical results, to establish financial targets on a consolidated basis and for other reasons, which are discussed below.

Some of these measures exclude net realized investment gains (losses), net of tax, and/or net unrealized investment gains (losses), net of tax, which can be significantly impacted by both discretionary and other economic factors and are not necessarily indicative of operating trends.

Other companies may calculate these measures differently, and, therefore, their measures may not be comparable to those used by the company’s management.

RECONCILIATION OF OPERATING INCOME AND CERTAIN OTHER NON-GAAP MEASURES TO NET INCOME

Operating income is net income excluding the after-tax impact of net realized investment gains and discontinued operations. Management uses operating income to analyze each segment’s performance and as a tool in making business decisions. Financial statement users also consider operating income when analyzing the results and trends of insurance companies. Operating earnings per share is operating income on a per common share basis.

RECONCILIATION OF ADJUSTED SHAREHOLDERS’ EQUITY TO SHAREHOLDERS’ EQUITY AND OPERATING RETURN ON EQUITY TO RETURN ON EQUITY

Average shareholders’ equity is (a) the sum of total shareholders’ equity excluding preferred stock at the beginning and end of each of the quarters for the period presented divided by (b) the number of quarters in the period presented times two. Adjusted shareholders’ equity is shareholders’ equity excluding net unrealized investment gains (losses), net of tax, net realized investment gains (losses), net of tax, for the period presented, preferred stock and discontinued operations. Adjusted average shareholders’ equity is average shareholders’ equity excluding net unrealized investment gains (losses), net of tax, for all quarters included in the calculation and, for each quarterly period included in the calculation, that quarter’s net realized investment gains (losses), net of tax.

RECONCILIATION OF PRE-TAX UNDERWRITING GAIN EXCLUDING CERTAIN ITEMS TO NET INCOME

Underwriting gain (loss) is net earned premiums and fee income less claims and claim adjustment expenses and insurance-related expenses. In the opinion of the company’s management, it is important to measure the profitability of each segment excluding the results of investing activities, which are managed separately from the insurance business.

13

This measure is used to assess each segment’s business performance and as a tool in making business decisions.  Pre-tax underwriting gain, excluding the impact of catastrophes and net favorable prior year loss reserve development, is the underwriting gain (loss) adjusted to exclude claims and claim adjustment expenses, reinstatement premiums and assessments related to catastrophes and loss reserve development related to time periods prior to the current year. In the opinion of the company’s management, this measure is meaningful to users of the financial statements to understand the company’s periodic earnings and the variability of earnings caused by the unpredictable nature (i.e., the timing and amount) of catastrophes and loss reserve development. This measure is also referred to as underlying underwriting margin or underlying underwriting gain (loss).

A catastrophe is a severe loss, resulting from natural and man-made events, including risks such as fire, earthquake, windstorm, explosion, terrorism and other similar events. Each catastrophe has unique characteristics, and catastrophes are not predictable as to timing or amount. Their effects are included in net and operating income and claims and claim adjustment expense reserves upon occurrence. A catastrophe may result in the payment of reinsurance reinstatement premiums and assessments from various pools. In the opinion of the company’s management, a discussion of the impact of catastrophes is meaningful to users of the financial statements to understand the company’s periodic earnings and the variability in periodic earnings caused by the unpredictable nature of catastrophes.

Net favorable (unfavorable) prior year loss reserve development is the increase or decrease in incurred claims and claim adjustment expenses as a result of the re-estimation of claims and claim adjustment expense reserves at successive valuation dates for a given group of claims, which may be related to one or more prior years. In the opinion of the company’s management, a discussion of loss reserve development is meaningful to users of the financial statements as it allows them to assess the impact between prior and current year development on incurred claims and claim adjustment expenses, net and operating income (loss), and changes in claims and claim adjustment expense reserve levels from period to period.

GAAP COMBINED RATIO AND ADJUSTMENTS FOR UNDERLYING GAAP COMBINED RATIO

GAAP combined ratio is the sum of the loss and loss adjustment expense ratio (loss and LAE ratio) and the underwriting expense ratio. For GAAP, the loss and LAE ratio is the ratio of incurred losses and loss adjustment expenses reduced by an allocation of fee income to net earned premiums. The underwriting expense ratio is the ratio of underwriting expenses incurred reduced by an allocation of fee income, and billing and policy fees and other to net earned premiums. A GAAP combined ratio under 100% generally indicates an underwriting profit.  A GAAP combined ratio over 100% generally indicates an underwriting loss. The GAAP combined ratio is an operating statistic that includes GAAP measures in the numerator and the denominator.

Underlying GAAP combined ratio represents the GAAP combined ratio excluding the impact of net prior year reserve development and catastrophes.  In the opinion of the company’s management, this measure is

14

meaningful to users of the financial statements to understand the company’s periodic underwriting profitability and the variability of underwriting profitability caused by the unpredictable nature of catastrophes and loss reserve development.

ADJUSTMENT TO NET WRITTEN PREMIUMS FOR THE IMPACT OF CHANGES IN FOREIGN EXCHANGE RATES

Adjusting for the impact of changes in foreign exchange rates allows the effect of foreign exchange rate differences to be isolated in the analysis of changes in various financial statement line items that are translated from a local currency to the company’s reporting currency, U.S. dollars. The impact is determined by assuming constant foreign exchange rates between periods as illustrated in the reconciliation below. In the opinion of the company’s management, this is useful in an analysis of the results of the International market and the Financial, Professional & International (FP&II) segment.

RECONCILIATION OF CERTAIN NON-GAAP MEASURES TO BOOK VALUE PER SHARE AND SHAREHOLDERS’ EQUITY

Book value per share is total common shareholders’ equity divided by the number of common shares outstanding. Adjusted book value per share is total common shareholders’ equity excluding the after-tax impact of net unrealized investment gains and losses, divided by the number of common shares outstanding. In the opinion of the company’s management, adjusted book value is useful in an analysis of a property casualty company’s book value as it removes the effect of changing prices on invested assets (i.e., net unrealized investment gains (losses), net of tax), which do not have an equivalent impact on unpaid claims and claim adjustment expense reserves. Tangible book value per share is adjusted book value per share excluding the after-tax value of goodwill and other intangible assets divided by the number of common shares outstanding. In the opinion of the company’s management, tangible book value per share is useful in an analysis of a property casualty company’s book value on a nominal basis as it removes certain effects of purchase accounting (i.e., goodwill and other intangible assets), in addition to the effect of changing prices on invested assets.

RECONCILIATION OF CERTAIN NON-GAAP MEASURES TO TOTAL CAPITALIZATION

Total capitalization is the sum of total shareholders’ equity and debt. Debt-to-capital ratio excluding net unrealized gain on investments is the ratio of debt to total capitalization excluding the after-tax impact of net unrealized investment gains and losses. In the opinion of the company’s management, the debt to capital ratio is useful in an analysis of the company’s financial leverage.
