PRESS RELEASE

REINSURANCE GROUP OF AMERICA REPORTS THIRD-QUARTER RESULTS

ST. LOUIS, October 28, 2013 – Reinsurance Group of America, Incorporated (NYSE: RGA), a leading global provider of life reinsurance, reported third-quarter net income of $138.0 million, or $1.93 per diluted share, compared with $144.5 million, or $1.95 per diluted share in the prior-year quarter. Operating income* of $152.9 million, or $2.14 per diluted share, increased from last year’s $99.9 million, or $1.35 per diluted share, with all operating segments posting significant gains over year-ago levels.

Consolidated net premiums increased six percent to $2,026.2 million from $1,912.7 million in the prior-year quarter, including an adverse effect of $51.7 million from foreign currency fluctuations. Investment income decreased seven percent to $369.4 million from $396.8 million in the year-earlier quarter, primarily attributable to a decrease in fair value of options contracts that are included in funds withheld at interest on the consolidated balance sheet and support the crediting rates for equity-indexed annuities. Excluding spread-based investment income and changes in value of associated derivatives, investment income rose 2.4 percent. The average portfolio yield decreased 23 basis points to 4.75 percent compared with the third quarter of 2012, reflecting the downward trend in interest rates over that period. The portfolio yield was down two basis points relative to the second quarter of this year, reflecting the stabilization in

interest rates in the shorter term. A generally stronger U.S. dollar quarter-over-quarter comparison reduced the current quarter’s operating income by approximately $3.2 million after taxes, or $0.05 per diluted share.

During the third quarter, the company recognized income tax benefits associated with an adjustment to the prior-year tax accrual, changes in foreign jurisdiction tax rates, income in jurisdictions with lower tax rates than the U.S. statutory rate, and other items. As a result, this quarter’s effective tax rate of 32.3 percent is below the expected rate of approximately 33 percent to 34 percent.

A. Greig Woodring, president and chief executive officer, commented, “We are pleased to report strong results this quarter, as we achieved an annualized operating return on equity of 13 percent. Operating earnings per share of $2.14 were considerably better than last year’s $1.35, as the year-ago period included elevated claims in several markets and a claim liability increase in Australia. Overall mortality and morbidity results this quarter were in line with expectations and stable across all operating segments, with favorable mortality experienced in several markets. We also had another strong quarter in our asset intensive and financial reinsurance businesses. Our efforts to return excess capital to shareholders increased operating earnings per share as well.

“Consolidated premiums grew six percent in reported U.S. dollars and nine percent with currencies held constant. Our ending book value per share for the quarter was $83.58 including AOCI, and $67.98 excluding AOCI.

“In September we issued $400 million of senior notes and expect to use the proceeds for general corporate purposes. We continued to repurchase shares in the third quarter, bringing our year-to-date total to approximately 4.2 million shares at a cost of $261.3 million. We have approximately $138.7 million remaining under our current $400 million authorization. We will continue to evaluate opportunistic share repurchases along with block acquisition opportunities, both of which are core components of our capital management strategy. Our excess capital position is approximately $600 million, reflecting the recent debt issuance and capital management activity.”

SEGMENT RESULTS

U.S.

The U.S. Traditional sub-segment reported pre-tax net income of $84.8 million for the quarter, up from $70.6 million last year. Pre-tax operating income increased to $90.1 million from $72.5 million in the prior-year period, when claims experience was less favorable. Claims experience in the current quarter was in line with expectations. Traditional net premiums rose six percent to $1,112.5 million from $1,045.8 million a year ago, reflecting stable growth in individual mortality and stronger growth in group reinsurance and individual health products.

The U.S. Asset Intensive business reported pre-tax income of $9.8 million compared with $78.0 million a year ago, which included a significant increase in the fair values of various embedded derivatives. Pre-tax operating income, which excludes the impact of those derivatives, increased to $38.0 million from $27.1 million last year. Current-quarter operating results benefited from favorable interest rate spreads, which improved the performance in the equity-indexed and fixed annuity businesses.

The U.S. Financial Reinsurance business reported another quarter of strong fee income and added pre-tax operating income of $11.5 million, up 39 percent from $8.3 million last year.

Canada

Canadian operations reported pre-tax net income of $41.9 million, up slightly from $37.5 million in the third quarter of 2012. Pre-tax operating income rose to $36.0 million this quarter from $28.1 million in the prior-year period. The increase was driven by favorable claims experience compared to the third quarter of 2012. Additionally, a relatively weaker Canadian dollar adversely affected pre-tax operating income by approximately $1.8 million compared to the prior-year period. Reported net premiums were up four percent to $236.1 million from $227.9 million last year, including an adverse foreign currency effect of $10.3 million. On a Canadian dollar basis, net premiums were up eight percent.

Asia Pacific

The Asia Pacific segment reported a pre-tax net income of $17.1 million compared with a pre-tax loss of $16.5 million in the third quarter of 2012. Pre-tax operating income totaled $12.6 million versus a pre-tax operating loss of $20.7 million last year. Current-quarter performance reflects break-even results in Australia and a generally strong performance in all other markets. We continue to manage the difficult business environment in Australia with no new significant developments during the quarter. The prior-period results reflected adverse claims experience and a $27.9 million increase in claims liabilities, both in Australia. Asia Pacific net premiums increased four percent to $343.1 million from $330.4 million in the prior year. Foreign currency fluctuations adversely affected premiums by approximately $33.0 million this period. Original currency premiums rose 14 percent over the third quarter of 2012. Foreign currency fluctuations adversely affected pre-tax operating income by approximately $2.2 million.

Europe & South Africa

Europe & South Africa operations reported pre-tax net income of $41.6 million versus $32.2 million in the year-ago quarter. Pre-tax operating income rose to $40.2 million this quarter from a strong $25.1 million last year, primarily due to higher fee income in Continental Europe and favorable mortality and morbidity claims experience in the U.K. The operations in South Africa also performed well this quarter. Foreign currency fluctuations adversely affected pre-tax operating income by approximately $0.4 million. Net premiums totaled $329.7 million, a nine percent increase from $303.1 million the year before, including an adverse currency effect of $8.3 million. On a local currency basis, net premiums increased 12 percent.

Corporate and Other

The Corporate and Other segment reported a pre-tax net loss of $4.7 million in the third quarter, compared with a pre-tax net loss of $8.4 million in the year-ago period. Pre-tax operating losses were $2.7 million in the current period and $5.9 million last year. Current-period overhead expenses were slightly below last year’s third quarter, and the income from internal capital charges allocated to the operating segments was slightly higher.

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.
