2014 Earnings Guidance

At its third quarter 2013 earnings conference call today, Prudential Financial, Inc. (the “Company”) is announcing its expectation that the Company will achieve Common Stock earnings per share in the range of $ 8.75 to $ 9.25 for 2014, based on after-tax adjusted operating income of the Financial Services Businesses. The 2014 earnings per share expectation assumes: (1) a December 31, 2014 S&P 500 Index (S&P) of 1,868, and an average S&P level of approximately 1,814 for 2014, (2) translation of Japanese yen earnings at a rate of 82 yen per U.S. dollar and Korean won earnings at a rate of 1,150 won per U.S. dollar, (3) interest rates based on forward yield curve, and (4) an effective income tax rate of approximately 28%. Management does not expect to provide updates during 2014 for its earnings per share guidance.

Adjusted operating income, which is not measured in accordance with generally accepted accounting principles (GAAP), should not be viewed as a substitute for income determined in accordance with GAAP, and our definition of adjusted operating income, which can be found below under “Non-GAAP Measure,” may differ from that used by other companies.

Non-GAAP Measures

Adjusted operating income is a non-GAAP measure of performance of our Financial Services Businesses. Adjusted operating income excludes “Realized investment gains (losses), net,” as adjusted, and related charges and adjustments. A significant element of realized investment gains and losses are impairments and credit-related and interest rate-related gains and losses. Impairments and losses from sales of credit-impaired securities, the timing of which depends largely on market credit cycles, can vary considerably across periods. The timing of other sales that would result in gains or losses, such as interest rate-related gains or losses, is largely subject to our discretion and influenced by market opportunities as well as our tax and capital profile.

Realized investment gains (losses) within certain of our businesses for which such gains (losses) are a principal source of earnings, and those associated with terminating hedges of foreign currency earnings and current period yield adjustments are included in adjusted operating income. Adjusted operating income excludes realized investment gains and losses from products that contain embedded derivatives, and from associated derivative portfolios that are part of a hedging program related to the risk of those products. Adjusted operating income also excludes gains and losses from changes in value of certain assets and liabilities relating to foreign currency exchange movements that have been economically hedged or considered part of our capital funding strategies for our international subsidiaries, as well as gains and losses on certain investments that are classified as other trading account assets.

Adjusted operating income also excludes investment gains and losses on trading account assets supporting insurance liabilities and changes in experience-rated contractholder liabilities due to asset value changes, because these recorded changes in asset and liability values are expected to ultimately accrue to contractholders. Trends in the underlying profitability of our businesses can be more clearly identified without the fluctuating effects of these transactions. In addition, adjusted operating income excludes the results of divested businesses, which are not relevant to our ongoing operations. Discontinued operations, which is presented as a separate component of net income under GAAP, is also excluded from adjusted operating income.

We believe that the presentation of adjusted operating income as we measure it for management purposes enhances understanding of the results of operations of the Financial Services Businesses by highlighting the results from ongoing operations and the underlying profitability of our businesses. However, adjusted operating income is not a substitute for income determined in accordance with GAAP, and the adjustments made to derive adjusted operating income are important to an understanding of our overall results of operations.

For additional information about adjusted operating income and the comparable GAAP measure, including reconciliation between the two, please refer to our Annual Report on Form 10-K for the year ended December 31, 2012, our subsequent Quarterly Reports on Form 10-Q and our third quarter 2013 earnings release filed with our Current Report on Form 8-K dated November 6, 2013, located on the Investor Relations Web site at www.investor.prudential.com. Additional historical information relating to the Company’s financial performance is also located on our Investor Relations website.
