2015 Earnings Guidance

On its 2015 financial outlook 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 $9.60 to $10.10 for 2015, based on after-tax adjusted operating income. The 2015 earnings per share expectation excludes potential market unlocking adjustments for deferred policy acquisition and other costs which would be regarded as “market driven and discrete items”, as well as expected integration costs related to the Company’s acquisition of The Hartford’s individual life insurance business on January 2, 2013, and assumes:

(1) a December 31, 2014 S&P 500 Index (“S&P”) of 2,020, 6% annual growth, and a December 31, 2015 S&P of 2,144,

(2) the translation of Japanese yen earnings at a rate of 91 yen per U.S. dollar and Korean won earnings at a rate of 1,120 won per U.S. dollar,

(3) interest rates based on averaging of forward yield curves, with the interest rate on ten-year U.S. Treasury securities rising to 2.97% by December 31, 2015, and

(4) an effective income tax rate of approximately 27%.

Management does not expect to provide updates during 2015 for its earnings per share guidance.

The conference call will be accompanied by a slide presentation on the Company’s financial outlook, including its earnings guidance. The Company is furnishing a copy of the slides as Exhibit 99.1 hereto.

Adjusted operating income, which is not measured in accordance with U.S. 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 Measure

Adjusted operating income is a non-GAAP measure of our performance. 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 are presented as a separate component of net income under GAAP, are also excluded from adjusted operating income.

For periods prior to the first quarter of 2015, adjusted operating income has been reported for our Financial Services Businesses, and accordingly, does not include the results of the Closed Block Business. Following the closing of the Class B Stock repurchase described in the Company’s Current Report on Form 8-K dated December 2, 2014, and the resulting elimination of the distinction between the Financial Services Businesses and the Closed Block Business, the Closed Block will be reported as a separate segment and treated as a divested business, and as such its results will be excluded from adjusted operating income.

We believe that the presentation of adjusted operating income as we measure it for management purposes enhances the understanding of our results of operations 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 a reconciliation between the two, please refer to our Annual Report on Form 10-K for the year ended December 31, 2013, and subsequent Quarterly Reports on Form 10-Q.
