Genworth Financial Announces First Quarter 2015 Results

Net Income Of $154 Million, Or $0.31 Per Share

Results Reflect Favorable Mortality In U.S. Life Insurance & Strong Mortgage Insurance Loss Ratios

Richmond, VA (April 28, 2015) – Genworth Financial, Inc. (NYSE: GNW) today reported results for the period ended March 31, 2015. The company reported net income¹ of $154 million, or $0.31 per diluted share, compared with net income of $184 million, or $0.37 per diluted share, in the first quarter of 2014. Net operating income² for the first quarter of 2015 was $156 million, or $0.31 per diluted share, compared with net operating income of $194 million, or $0.39 per diluted share, in the first quarter of 2014.

Strategic Update

The company continues to make progress on its review of strategic options in order to position the company for future success and is actively engaged in three areas: (1) strengthening its mortgage insurance businesses and long term care insurance (LTC) capital, earnings and sales; (2) simplifying the business portfolio; and (3) increasing its financial strength and flexibility. In addition, the company continues to pursue the planned sale of its non-core lifestyle protection insurance business. The company

1

believes the execution of these strategic initiatives will improve operating returns, support compliance with the Private Mortgage Insurer Eligibility Requirements (PMIERs), reduce debt levels, increase LTC capital buffers and maintain solid holding company cash levels.

As disclosed on April 17, 2015, the company estimates $500 to $700 million of additional capital will be required to be fully compliant with the final PMIERs by the effective date of December 31, 2015. The company will comply with the final PMIERs by the effective date and intends to utilize both reinsurance and holding company cash to meet the additional capital requirement.

“Regarding the quarter, we are encouraged with the results in spite of continued challenges and remain focused on initiatives aimed at strengthening and building our businesses,” said Tom McInerney, President and CEO. “During the first quarter, we made significant progress on our strategic review and are developing next steps to position the company for future success. We look forward to updating you on specific actions as appropriate.”

Net investment losses, net of taxes and other adjustments, were $2 million in the quarter, compared to $10 million in the prior year. Net investment income decreased to $803 million, compared to $819 million in the prior quarter primarily from lower reinvestment rates and unfavorable foreign exchange. The reported yield for the current quarter was 4.51 percent. The core yield² was down compared to the prior quarter at 4.28 percent.

Net operating income (loss) results are summarized in the table below:

Net operating income (loss) excludes net investment gains (losses), goodwill impairments, gains (losses) on the sale of businesses, gains (losses) on the early extinguishment of debt, gains (losses) on insurance block transactions, restructuring costs and other adjustments, net of taxes. A reconciliation of net operating income (loss) of segments and Corporate and Other activities to net income (loss) is included at the end of this press release.

Unless specifically noted in the discussion of results for the International Mortgage Insurance and International Protection segments, references to percentage changes exclude the impact of translating foreign denominated activity into U.S. dollars (foreign exchange). Percentage changes, which include the impact of foreign exchange, are found in a table at the end of this press release. The impact of foreign exchange on results in the first quarter of 2015 was an unfavorable impact of $7 million versus the prior quarter and an unfavorable impact of $8 million versus the prior year.

Global Mortgage Insurance Division

Global Mortgage Insurance Division had net operating income of $116 million, compared with $83 million in the prior quarter and $132 million a year ago.

Canada Mortgage Insurance

Canada reported net operating income of $40 million versus $36 million in the prior quarter and $41 million in the prior year. The loss ratio in the quarter was 22 percent, down four points from the prior quarter from fewer new delinquencies, net of cures and up two points from the prior year from a higher average reserve per delinquency, which was partially offset by a decrease in the number of new delinquencies, net of cures. Results included lower expenses versus the prior quarter and prior year and unfavorable foreign exchange. Flow NIW was down 36 percent⁴ sequentially from a seasonally smaller originations market and up 24 percent⁴ year over year primarily from a larger originations market. In addition, the company completed several bulk transactions in the quarter of approximately $5.0 billion in total, consisting of low loan-to-value prime loans, reflecting its selective participation in this market.

Australia Mortgage Insurance

Australia reported net operating income of $30 million versus $33 million in the prior quarter and $62 million in the prior year. Results in the quarter reflected a $21 million decrease in net operating income versus the prior year as a result of the minority IPO of 33.8 percent of the Australia MI business, which was completed on May 21, 2014. The loss ratio in the quarter was 15 percent, flat sequentially and down two points from the prior year. During the quarter, the company accrued a $7 million pre-tax receivable for

4

expected recoveries relating to paid claims reflecting its experience of successful borrower recovery activity, favorably impacting the loss ratio by nine points. New delinquencies were up 14 percent and cures were down 17 percent sequentially reflecting normal seasonal variation. Results were also impacted by unfavorable foreign exchange versus both the prior quarter and prior year. Flow NIW was down 20 percent⁴ sequentially primarily from seasonal variation and other market factors and down 17 percent⁴ year over year from a smaller mortgage insurance market.

Other Countries Mortgage Insurance

Other Countries had a net operating loss of $6 million, compared to $7 million in the prior quarter and $4 million in the prior year.

U.S. Mortgage Insurance

U.S. MI net operating income was $52 million, compared with $21 million in the prior quarter and $33 million in the prior year. The loss ratio in the current quarter was 33 percent, down 28 points sequentially reflecting seasonally lower new delinquencies and favorable net cures and aging of existing delinquencies. New flow delinquencies decreased approximately 12 percent from the prior quarter from seasonal variation and decreased approximately 22 percent from the prior year, reflecting the continued burn through of delinquencies from the 2005 to 2008 book years.

Flow NIW of $6.3 billion decreased nine percent from the prior quarter from a seasonally smaller purchase originations market and increased 62 percent versus the prior year primarily from a larger purchase originations market, higher refinance activity and an increase in estimated market share. During the quarter, the company increased its single premium lender paid new insurance written reflecting its selective participation in this market. Future volumes of this product will vary in part depending on the company’s evaluation of the risk return profile of these transactions.

U.S. Life Insurance Division

U.S. Life Insurance Division net operating income was $81 million, compared with a net operating loss of $482 million in the prior quarter and net operating income of $94 million a year ago.

Long Term Care Insurance

LTC net operating income was $10 million, compared with a net operating loss of $506 million in the prior quarter and net operating income of $46 million in the prior year. Benefits and other changes in policy reserves decreased $506 million after-tax versus the prior quarter and increased $66 million after-tax versus the prior year. The current quarter included favorable mortality on existing claims versus both the prior quarter and prior year partially offset by unfavorable severity given the mix of new claims with a higher average reserve. Results in the quarter included net unfavorable items of $7 million after-tax reflecting a refinement to a reserve calculation on the acquired block of business, partially offset primarily by a correction related to reinsurance. During the quarter, the company began implementing a process to accrue for profits followed by losses on business written since late 1995, but it had no impact on the current quarter financial results. The prior quarter impact of the unlocking of assumptions associated with the active life reserves on the acquired block, as well as additional adjustments to reserves, was $494 million after-tax. The loss ratio in the current quarter was 72 percent.

Results for the quarter included lower benefits from reduced benefit options of $3 million after-tax versus the prior quarter related to the premium increases approved and implemented to date.

6

Individual LTC sales of $10 million were lower than the prior quarter and the prior year. Sales are expected to continue at low levels in the near term due to the 2014 introduction of a higher priced product and ratings pressure, but build over time as new products are introduced.

Life Insurance

Life insurance net operating income was $40 million, compared with $1 million in the prior quarter and $21 million in the prior year. Results in the quarter included favorable mortality versus pricing, in line with the prior quarter and better than the prior year, and favorable term life insurance reserve development from aging of the block and lower new business. During the quarter, the company completed a reinsurance transaction that reduced paid claims that were offset with lower premiums resulting in a minimal reduction in net operating income, but will reduce future excess reserve financing costs. Results in the prior quarter included an unfavorable correction to a reserve calculation on a reinsurance transaction of $32 million. Sales of $17 million decreased compared to the prior quarter and the prior year. Linked benefit product deposits were $41 million in the quarter, down from $42 million in the prior quarter and up from $25 million in the prior year.

Fixed Annuities

Fixed annuities net operating income was $31 million, compared with $23 million in the prior quarter and $27 million in the prior year. Results in the quarter reflected favorable mortality versus both the prior quarter and prior year and lower lapses versus the prior quarter. Sales in the quarter totaled $326 million, down sequentially and versus the prior year given the lower interest rate environment and ratings impacts.

Corporate and Other Division

Corporate and Other Division net operating loss was $41 million, compared with $17 million in the prior quarter and $32 million in the prior year.

International Protection net operating income was zero for the quarter, compared with a net operating loss of $4 million in the prior quarter and net operating income of $7 million in the prior year. Results in the prior quarter reflected $4 million of net unfavorable items and the prior year reflected $4 million of favorable tax adjustments.

7

Runoff net operating income was $11 million, compared with $16 million in the prior quarter and $12 million in the prior year. Results in the current quarter reflect less favorable taxes partially offset by favorable equity market performance versus the prior quarter primarily impacting variable annuity products.

Corporate and Other net operating loss was $52 million, compared with $29 million in the prior quarter and $51 million in the prior year. Results in the prior quarter reflected favorable year-end tax benefits.

Use of Non-GAAP Measures

This press release includes the non-GAAP financial measures entitled “net operating income (loss)” and “net operating income (loss) per share.” Operating earnings (loss) per share is derived from net operating income (loss). The chief operating decision maker evaluates segment performance and allocates resources on the basis of net operating income (loss). The company defines net operating income (loss) as income (loss) from continuing operations excluding the after-tax effects of income attributable to noncontrolling interests, net investment gains (losses), goodwill impairments, gains (losses) on the sale of businesses, gains (losses) on the early extinguishment of debt, gains (losses) on insurance block transactions, restructuring costs and infrequent or unusual non-operating items. Gains (losses) on insurance block transactions are defined as gains (losses) on the early extinguishment of non-recourse funding obligations, early termination fees for other financing restructuring and/or resulting gains (losses) on reinsurance restructuring for certain blocks of business. The company excludes net investment gains (losses) and infrequent or unusual non-operating items because the company does not consider them to be related to the operating performance of the company’s segments and Corporate and Other activities. A component of the company’s net investment gains (losses) is the result of impairments, the size and timing of which can vary significantly depending on market credit cycles. In addition, the size and timing of other investment gains (losses) can be subject to the company’s discretion and are influenced by market opportunities, as well as asset-liability matching considerations. Goodwill impairments, gains (losses) on the sale of businesses, gains (losses) on the early extinguishment of debt, gains (losses) on insurance block transactions and restructuring costs are also excluded from net operating income (loss) because, in the company’s opinion, they are not indicative of overall operating trends. Infrequent or unusual non-operating items are also excluded from net operating income (loss) if, in the company’s opinion, they are not indicative of overall operating trends.

In the first quarter of 2015, the company modified its definition to explicitly state that restructuring costs, which were previously included in the infrequent and unusual category, are excluded from net operating income (loss). There were no restructuring costs in the periods presented.

In the fourth quarter of 2014, the company recorded goodwill impairments of $129 million, net of taxes, in the long term care insurance business and $145 million, net of taxes, in the life insurance business.

There were no infrequent or unusual items excluded from net operating income (loss) during the periods presented other than the following items. There was a $66 million net tax impact in the fourth quarter of 2014 from potential business portfolio changes. Although no decisions have been made, the company recognized a tax charge of $174 million in the fourth quarter of 2014 associated with the Australian mortgage insurance business as the company can no longer assert its intent to permanently reinvest earnings in that business. In connection with the company’s plans to sell the lifestyle protection insurance business, the company completed an internal debt restructuring recognizing tax benefits of $108 million in the fourth quarter of 2014.

While some of these items may be significant components of net income (loss) available to Genworth’s common stockholders in accordance with GAAP, the company believes that net operating income (loss) and measures that are derived from or incorporate net operating income (loss), including net operating income (loss) per common share on a basic and diluted basis, are appropriate measures that are useful to investors because they identify the income (loss) attributable to the ongoing operations of the business. Management also uses net operating income (loss) as a basis for determining awards and compensation for senior management and to evaluate performance on a basis comparable to that used by analysts. However, the items excluded from net operating income (loss) have occurred in the past and could, and in some cases will, recur in the future. Net operating income (loss) and net operating income (loss) per common share on a basic and diluted basis are not substitutes for net income (loss) available to Genworth’s common stockholders or net income (loss) available to Genworth’s common stockholders per common share on a basic and diluted basis determined in accordance with GAAP. In addition, the company’s definition of net operating income (loss) may differ from the definitions used by other companies.

The tables at the end of this press release reflect net operating income (loss) as determined in accordance with accounting guidance related to segment reporting, and a reconciliation of net operating income (loss) of the company’s segments and Corporate and Other activities to net income (loss) available to Genworth’s common stockholders for the three months ended March 31, 2015 and 2014, as well as for the three months ended December 31, 2014.

Adjustments to reconcile net income (loss) attributable to Genworth’s common stockholders and net operating income (loss) assume a 35 percent tax rate and are net of the portion attributable to noncontrolling interests. Net investment gains (losses) are also adjusted for deferred acquisition costs and other intangible amortization and certain benefit reserves.

This press release also includes non-GAAP financial measures entitled “net income (loss) before net income attributable to noncontrolling interests in the Australia MI business” and “net operating income (loss) before net operating income attributable to noncontrolling interests in the Australia MI business.” The company defines net income (loss) before net income attributable to noncontrolling interests in the Australia MI business and net operating income (loss) before net operating income attributable to noncontrolling interests in the Australia MI business as net income (loss) or net operating income (loss), as applicable, adjusted for net income attributable to noncontrolling interests in the Australia MI business but before noncontrolling interests in the Canada MI business. These measures are presented as they are comparable to net income (loss) and net operating income (loss) for the first quarter of 2014. However, net income (loss) before net income attributable to noncontrolling interests in the Australia MI business and net operating income (loss) before net operating income attributable to noncontrolling interests in the Australia MI business are not substitutes for net income (loss) and net operating income (loss) determined in accordance with GAAP. A reconciliation of net income (loss) before net income attributable to noncontrolling interests in the Australia MI business and net operating income (loss) before net operating income attributable to noncontrolling interests in the Australia MI business to net income (loss) and net operating income (loss) is included in a table at the end of this press release.

This press release includes the non-GAAP financial measure entitled “core yield” as a measure of investment yield. The company defines core yield as the investment yield adjusted for those items that are not recurring in nature. Management believes that analysis of core yield enhances understanding of the investment yield of the company. However, core yield is not a substitute for investment yield determined in accordance with GAAP. In addition, the company’s definition of core yield may differ from the definitions used by other companies. A reconciliation of core yield to reported GAAP yield is included in a table at the end of this press release.

Results of Operations by Segment

In the first quarter of 2015, the company revised how it allocates the consolidated provision for income taxes to its operating segments to simplify the process and reflect how the chief operating decision maker is evaluating segment performance. The revised methodology applies a specific tax rate to the pre-tax income (loss) of each segment, which is then adjusted in each segment to reflect the tax attributes of items unique to that segment such as foreign income. The difference between the consolidated provision for income taxes and the sum of the provision for income taxes in each segment is reflected in Corporate and Other activities. Previously, the company calculated a unique income tax provision for each segment based on quarterly changes to tax attributes and implications of transactions specific to each product within the segment.

The annually-determined tax rates and adjustments to each segment’s provision for income taxes are estimates which are subject to review and could change from year to year. Prior year amounts have not been re-presented to reflect this revised presentation and are, therefore, not comparable to the current year provision for income taxes by segment. However, the company does not believe that the previous methodology would have resulted in a materially different segment-level provision for income taxes.

Definition of Selected Operating Performance Measures

The company reports selected operating performance measures including “sales” and “insurance in force” or “risk in force” which are commonly used in the insurance industry as measures of operating performance.

Management regularly monitors and reports sales metrics as a measure of volume of new and renewal business generated in a period. Sales refer to: (1) new insurance written for mortgage insurance; (2) annualized first-year premiums for long term care and term life insurance products; (3) annualized first-year deposits plus five percent of excess deposits for universal and term universal life insurance products; (4) 10 percent of premium deposits for linked-benefits products; (5) new and additional premiums/deposits for fixed annuities; and (6) net premiums written for the lifestyle protection insurance business. Sales do not include renewal premiums on policies or contracts written during prior periods. The company considers new insurance written, annualized first-year premiums/deposits, premium equivalents, new premiums/deposits and net premiums written to be a measure of the company’s operating performance because they represent a measure of new sales of insurance policies or contracts during a specified period, rather than a measure of the company’s revenues or profitability during that period.

Management regularly monitors and reports insurance in force and risk in force. Insurance in force for the international mortgage and U.S. mortgage insurance businesses is a measure of the aggregate face value of outstanding insurance policies as of the respective reporting date. For risk in force in the international mortgage insurance business, the company has computed an “effective” risk in force amount, which recognizes that the loss on any particular loan will be reduced by the net proceeds received upon sale of the property. Effective risk in force has been calculated by applying to insurance in force a factor of 35 percent that represents the highest expected average per-claim payment for any one underwriting year over the life of the company’s businesses in Canada and Australia. Risk in force for the U.S. mortgage insurance business is the obligation that is limited under contractual terms to the amounts less than 100 percent of the mortgage loan value. The company considers insurance in force and risk in force to be measures of the company’s operating performance because they represent measures of the size of the business at a specific date which will generate revenues and profits in a future period, rather than measures of the company’s revenues or profitability during that period.

Management also regularly monitors and reports a loss ratio for the company’s businesses. For the mortgage and lifestyle protection insurance businesses, the loss ratio is the ratio of incurred losses and loss adjustment expenses to net earned premiums. For the long term care insurance business, the loss ratio is the ratio of benefits and other changes in reserves less tabular interest on reserves less loss adjustment expenses to net earned premiums. The company considers the loss ratio to be a measure of underwriting performance in these businesses and helps to enhance the understanding of the operating performance of the businesses.

An assumed tax rate of 35 percent is utilized in certain adjustments to net operating income (loss) and in the explanation of specific variances of operating performance and investment results.

These operating performance measures enable the company to compare its operating performance across periods without regard to revenues or profitability related to policies or contracts sold in prior periods or from investments or other sources.
