Exhibit 99.1

PRESS RELEASE

REINSURANCE GROUP OF AMERICA REPORTS SECOND-QUARTER RESULTS

ST. LOUIS, July 18, 2013 – Reinsurance Group of America, Incorporated (NYSE: RGA), a leading global provider of life reinsurance, reported second-quarter net losses of $49.6 million, or $0.69 per diluted share, compared with net income of $141.1 million, or $1.91 per diluted share in the prior-year quarter. Operating losses* totaled $71.8 million, or $0.99 per diluted share in the current quarter, versus operating income of $122.3 million, or $1.65 per diluted share, last year. Losses this quarter were primarily attributable to an after-tax charge of approximately $184 million, or $2.53 per diluted share, to increase claims liabilities in Australia.

Consolidated net premiums increased four percent to $2,035.2 million from $1,950.7 million in the prior-year quarter, including an adverse effect of $21.2 million from foreign currency fluctuations. Investment income increased 35 percent to $444.2 million from $328.3 million in the year-earlier quarter, primarily attributable to a significant increase in fair value of options contracts, which are included in funds withheld at interest and support the crediting rates for equity-indexed annuities.

Excluding spread-based investment income and changes in value of associated derivatives, the average portfolio yield decreased to 4.77 percent from 5.06 percent in the second quarter of 2012, reflecting the ongoing low interest rate environment. Although the U.S. dollar generally appreciated against most currencies compared to the second quarter of 2012, net foreign currency fluctuations benefited the current quarter’s operating income by approximately $8.8 million after taxes, or $0.12 per diluted share, primarily due to the losses in Australia.

As a result of the significant charge in Australia this quarter, the company recorded a net operating tax benefit of approximately $36.5 million, resulting in an effective tax rate of 33.7 percent.

A. Greig Woodring, president and chief executive officer, explained, “The significant charge in our Australia operations was primarily associated with the group business which, as we have indicated previously, has been quite challenging for some time. We increased claims liabilities in that operation several times in recent years. We have just completed a comprehensive claims analysis within the last week, and that analysis indicates a more dramatic deterioration than we previously anticipated, a development we believe to be consistent across the industry. We have reflected not only the observed underperformance, as we have in the past, but also potential additional deterioration in the projection of future claims development on that entire book of business, through the end of the premium guarantee periods.

“The largest increase in liabilities relates to the total and permanent disability coverage, and, to a lesser extent, disability income benefits. The Australia market is the only one in which we have significant exposure to this form of total and permanent disability benefit. Not only have claim incidences for those benefits been increasing, but the claim lags throughout the claim reporting process have also risen at a significant rate. There appears to be a number of environmental factors in the current Australian market leading to a significant rise in claim levels and reporting lags, and we are working with direct insurance companies to better manage this business. The ceding companies generally retain a significant amount of risk even as they utilize the reinsurance market.

“The after-tax charge of approximately $184 million reduces our excess capital position by the same amount. Even though these group contracts are typically only three years in duration, the increase in loss ratios to this extent, compared to pricing, has created the need for this significant increase in claims liabilities. This situation is manageable and we believe we have aggressively addressed the issue in terms of the ongoing adequacy of the higher reserve and claim liability levels.”

Woodring continued, “The current environment makes it very difficult to price new business with any degree of confidence. We have been quoting very selectively on new group business since mid-2011 and we have not won any material new group business in that period. At this time, we are suspending all quoting activity in the Australian group total and permanent disability market indefinitely and will continue to be extremely selective in other aspects of that group market until it stabilizes and the products become more sustainable.

“Outside of the Australia operation, after-tax operating income per share was approximately $1.70. Operating performance was strong in our asset-intensive business line and mixed claims experience elsewhere was generally in line with overall expectations. Consolidated reported premium growth of four percent was also generally in line with expectations, and included an adverse effect of approximately $21.2 million from fluctuations in foreign currency exchange rates. In original currencies, net premiums increased over five percent in the second quarter compared to the prior-year period. Our book value per share is $82.97 including AOCI, and $66.31 excluding AOCI.

“We repurchased additional shares in the second quarter, bringing our year-to-date total to approximately 3.7 million shares at a cost of $230.5 million. We have $170 million remaining under our current authorization, which was increased from $300 million to $400 million this quarter. Additionally, we increased our quarterly shareholder dividend 25 percent to $0.30 per share. We continue to execute our capital management strategy, opportunistically repurchasing shares and evaluating opportunities to grow our business. Our excess capital position is approximately $200 million, reflecting the recent capital management activity and charges in our Australia operations.

“We recently announced that our primary operating subsidiary, RGA Reinsurance Company, received a preparatory license from the China Insurance Regulatory Commission. We are excited about this opportunity and expect to receive a branch license next year, which will allow us to fully operate in the Chinese life reinsurance market.”

SEGMENT RESULTS

U.S.

The U.S. Traditional sub-segment reported pre-tax net income of $89.4 million for the quarter, down from $96.3 million last year. Pre-tax operating income totaled $85.7 million, a decrease from $95.5 million in the prior-year period. While claims experience was in line with last year’s second quarter and current expectations, policy acquisition costs as a percentage of premiums, which can fluctuate from period to period, were slightly higher this quarter. That type of fluctuation is expected to even out over the course of the year. In addition, relatively lower investment yields adversely affected results in the current period. Net premiums rose four percent, to $1,124.3 million from $1,082.4 million a year ago.

The U.S. Asset-Intensive business reported pre-tax income of $69.2 million, up from $34.6 million a year ago, including changes in the fair values of various free-standing and embedded derivatives. Pre-tax operating income, which excludes the impact of those derivatives, increased to $40.2 million from $16.6 million last year. The current-period result was better than expected and reflects strong performance in the U.S. equity market, which bolstered results in the equity indexed annuity line of business. Fixed annuities also performed well.

The U.S. Financial Reinsurance business added pre-tax operating income of $11.9 million this quarter, up 24 percent from $9.6 million last year. This business continues to contribute strong fee income to this segment.

Canada

Canadian operations reported pre-tax net income of $35.7 million, up slightly from $35.0 million in the second quarter of 2012. Pre-tax operating income was $31.7 million this quarter, a four percent increase from $30.5 million in the prior-year period. This segment’s claims experience was slightly higher than expected in the current period. Additionally, a relatively weaker Canadian dollar adversely affected pre-tax operating income by approximately $0.4 million compared to the prior-year period. Reported net premiums were up eight percent to $239.6 million from $221.2 million last year, including an adverse foreign currency effect of $3.1 million. On a Canadian dollar basis, net premiums were up 10 percent.

Asia Pacific

The Asia Pacific segment reported a pre-tax net loss of $290.4 million compared with pre-tax net income of $23.9 million in the second quarter of 2012. Pre-tax operating losses totaled $285.7 million versus pre-tax operating income of $22.7 million last year. As indicated above, current-period losses were driven by a $274.1 million pre-tax increase in Australian claims liabilities as well as poor claims experience in the Australian operation’s individual businesses. In total, the Australia operation reported a pre-tax operating loss of $299.7 million for the quarter.

Outside of Australia, all of the markets in this segment performed better than expected, particularly Hong Kong and Southeast Asia. Asia Pacific net premiums increased three percent to $340.5 million from $331.9 million in the prior year. Foreign currency fluctuations adversely affected premiums by approximately $8.1 million this period. Original currency premiums rose five percent over the second quarter of 2012. Aside from Australia operations, foreign currency fluctuations adversely affected pre-tax operating income by approximately $2.0 million.

Europe & South Africa

Europe & South Africa operations reported pre-tax net income of $15.8 million versus $19.6 million in the year-ago quarter. Pre-tax operating income decreased to $15.3 million this quarter from $18.4 million last year, primarily due to higher-than-expected mortality claims in the U.K. Results from the U.K.’s critical illness and longevity businesses were slightly better than expected. Foreign currency fluctuations adversely affected pre-tax operating income by approximately $1.0 million. Net premiums totaled $319.4 million, up from $310.1 million the year before, including an adverse currency effect of $10.0 million. On a local currency basis, net premiums increased 6 percent.

Corporate and Other

The Corporate and Other segment reported a pre-tax net loss of $6.2 million in the second quarter, compared with a pre-tax net loss of $3.2 million in the year-ago period. Pre-tax operating losses were $7.5 million in the current period and $5.8 million last year, reflecting lower other revenues in the current quarter.

Use of Non-GAAP Financial Measures

RGA uses a non-GAAP financial measure called operating income as a basis for analyzing financial results. This measure also serves as a basis for establishing target levels and awards under RGA’s management incentive programs. Management believes that operating income, on a pre-tax and after-tax basis, better measures the ongoing profitability and underlying trends of the company’s continuing operations, primarily because that measure excludes substantially all of the effect of net investment related gains and losses, as well as changes in the fair value of certain embedded derivatives and related deferred acquisition costs. These items can be volatile, primarily due to the credit market and interest rate environment, and are not necessarily indicative of the performance of the company’s underlying businesses. Additionally, operating income excludes any net gain or loss from discontinued operations, the cumulative effect of any accounting changes, and other items that management believes are not indicative of the company’s ongoing operations. The definition of operating income can vary by company and is not considered a substitute for GAAP net income. Reconciliations to GAAP net income are provided in the following tables. Additional financial information can be found in the Quarterly Financial Supplement on RGA’s Investor Relations website at www.rgare.com in the “Quarterly Results” tab and in the “Featured Report” section.

Book value per share outstanding before impact of AOCI is a non-GAAP financial measure that management believes is important in evaluating the balance sheet in order to ignore the effects of unrealized amounts primarily associated with mark-to-market adjustments on investments and foreign currency translation.

Operating return on equity is a non-GAAP financial measure calculated as operating income divided by average shareholders’ equity excluding AOCI.
