Exhibit 99.1

RenaissanceRe Reports Net Income of $165.0 Million for the First Quarter of 2010 or $2.73 Per Diluted Common Share; Operating Income of $116.5 Million or $1.91 Per Diluted Common Share.

Pembroke, Bermuda, April 27, 2010 – RenaissanceRe Holdings Ltd. (NYSE: RNR) today reported net income available to common shareholders of $165.0 million or $2.73 per diluted common share in the first quarter of 2010, compared to $97.3 million or $1.57 per diluted common share for the first quarter of 2009. Operating income available to common shareholders was $116.5 million or $1.91 per diluted common share in the first quarter of 2010, compared to $94.2 million or $1.52 per diluted common share in the first quarter of 2009. Operating income excludes net realized and unrealized gains on fixed maturity investments of $48.6 million and net other-than-temporary impairments of $33 thousand in the first quarter of 2010 and net realized gains on fixed maturity investments of $22.1 million and net other-than-temporary impairments of $19.0 million in the first quarter of 2009.

The Company reported an annualized return on average common equity of 20.9% and an annualized operating return on average common equity of 14.8% in the first quarter of 2010, compared to 16.0% and 15.5%, respectively, in the first quarter of 2009. Book value per common share increased to $53.86 at March 31, 2010, a 4.2% increase in the first quarter of 2010, compared to a 2.3% increase in the first quarter of 2009.

Neill A. Currie, CEO, commented: “Industry insured catastrophe losses were among the highest recorded for a first quarter. We generated an annualized operating ROE of 14.8% and grew our book value per share by over 4%, including the $124.5 million of net negative impact from these catastrophes. Favorable reserve development and strong investment performance were key drivers for the quarter.”

Mr. Currie continued: “An event like Xynthia is a relatively common occurrence, whereas the Chilean earthquake had a much lower probability of occurring. We are in the business of protecting our clients from such events and our estimated losses were well within our modeled expectations.”

FIRST QUARTER 2010 RESULTS

Net Impact of the Chilean Earthquake and European Windstorm Xynthia (“Xynthia”)

The Company recorded $124.5 million of net negative impact from the Chilean earthquake and Xynthia in the first quarter of 2010. Net negative impact includes the sum of estimates of net claims and claim expenses incurred, earned reinstatement premiums assumed and ceded, lost profit commissions and noncontrolling interest. The Company’s estimate of losses from the Chilean earthquake and Xynthia are based on initial industry insured loss estimates, market share analysis, the application of the Company’s modeling techniques, and a review of the Company’s in-force contracts. Given the preliminary nature of the information available, inadequacies in the data provided thus far by industry participants, the magnitude and recent occurrence of the events, the expected lengthy claims development period, in particular for the Chilean earthquake, and other factors and uncertainties inherent in loss estimation, meaningful uncertainty remains regarding losses from these events and the Company’s actual ultimate net losses from these events will vary from these estimates, perhaps materially. Changes in these estimates will be recorded in the period in which they occur.

See the supplemental financial data below for additional information detailing the net negative impact from these events on the Company’s consolidated financial statements and its Reinsurance segment results.

Underwriting Results

Gross premiums written for the first quarter of 2010 decreased 5.8%, to $563.5 million, compared to $598.3 million in the first quarter of 2009. The decrease in gross premiums written was primarily driven by a decrease in gross premiums written in the Company’s catastrophe unit and Insurance segment, partially offset by an increase in gross premiums written in the Company’s specialty unit, as discussed in more detail below. Included in the Company’s gross premiums written is $27.0 million of reinstatement premium written as a direct result of the losses from the Chilean earthquake which occurred in the first quarter of 2010. The Company generated $89.8 million of underwriting income and had a combined ratio of 67.7% in the first quarter of 2010, compared to $131.2 million of underwriting income and a 56.5% combined ratio in the first quarter of 2009, principally driven by the decrease in gross premiums written and an increase in operating expenses during the first quarter of 2010, and partially offset by a decrease in net claims and claim expenses incurred as a result of $161.7 million of favorable development on prior years reserves. Current accident year net claims and claim expenses increased to $240.8 million in the first quarter of 2010, compared to $78.9 million in the first quarter of 2009, with the $161.8 million increase principally driven by net claims and claim expenses associated with the Chilean earthquake and Xynthia.

Reinsurance Segment

Gross premiums written for the Company’s Reinsurance segment decreased $20.5 million, or 3.9%, to $512.4 million in the first quarter of 2010, compared to $532.9 million in the first quarter of 2009, principally due to a decline of $37.3 million, or 8.1%, in gross premiums written in the Company’s catastrophe unit which was impacted by reduced pricing on the January 1st renewals. The Company’s specialty premiums increased $3.0 million, or 4.1%, to $74.5 million in the first quarter of 2010, compared to $71.5 million in the first quarter of 2009. In addition, commencing in the first quarter of 2010, the Company’s Lloyd’s unit, which recently commenced operations, and is presented as a separate unit within the Company’s Reinsurance segment, generated $14.0 million of gross premiums written during the first quarter of 2010. In the first quarter of 2010, the Company’s managed catastrophe premiums, excluding $27.0 million of reinstatement premium written as a result of the losses from the Chilean earthquake, decreased 11.7% from the first quarter of 2009. The Company’s managed specialty premiums increased 14.9% in the first quarter of 2010 compared to the first quarter of 2009, due to several new contracts the Company added to its portfolio including $7.7 million of specialty premium written within the Company’s recently established Lloyd’s unit. The Company’s Reinsurance segment premiums are prone to significant volatility due to the timing of contract inception and also due to the business being characterized by a relatively small number of relatively large transactions.

The Company’s Reinsurance segment generated $84.5 million of underwriting income and had a combined ratio of 66.2% in the first quarter of 2010, compared to $161.3 million of underwriting income and a 28.6% combined ratio in the first quarter of 2009. The decrease in underwriting income in the first quarter of 2010 was primarily due to the comparably high level of insured catastrophe events in the quarter, principally due to the Chilean earthquake and Xynthia, combined with increased operational costs, in part due to the Company’s new Lloyd’s unit, as well as an increase in our headcount and related operating expenses, partially offset by increased net premiums earned. Current accident year net claims and claims expenses increased $165.4 million to $206.8 million in the first quarter of 2010, compared to $41.3 million in the first quarter of 2009, primarily related to increased losses within the catastrophe unit. The catastrophe unit incurred current accident year net claims and claim expenses of $181.1 million, principally due to $175.6 million of losses related to the Chilean earthquake and Xynthia.

Following is supplemental financial data regarding the net financial statement impact on the Company’s first quarter 2010 results within the Company’s Reinsurance segment due to the Chilean earthquake and Xynthia:

The Reinsurance segment experienced $105.2 million of favorable development on prior years reserves in the first quarter of 2010. This includes $73.5 million of net favorable development within the Company’s specialty unit and $31.6 million of net favorable development within the Company’s catastrophe unit. The favorable development within the Company’s specialty unit includes $31.4 million associated with actuarial assumption changes made in the first quarter of 2010, principally in the Company’s casualty clash and surety lines of business and partially offset by an increase in reserves within the Company’s workers compensation per risk line of business, principally as a result of revised initial expected loss ratios and loss development factors due to actual experience coming in better than expected; $25.9 million due to a decrease in case reserves and additional case reserves, which are reserves established at the contract level for specific losses or large events; and $16.3 million due to certain actual reported losses coming in better than expected in the current quarter on prior accident years events. Within the Company’s catastrophe unit the $31.6 million of favorable development was due to better than expected claims emergence which resulted in a reduction in ultimate net losses associated with the 2005 hurricanes of $8.1 million, 2008 hurricanes of $6.9 million, European windstorm Klaus of $4.5 million and the 2009 Austrian hail storms of $4.0 million, with the remainder due to a reduction in ultimate losses on a large number of relatively small catastrophes. In the first quarter of 2009, the Reinsurance segment experienced $24.7 million of favorable development on prior year reserves, principally attributable to reduced estimated ultimate losses on certain small catastrophes within the Company’s catastrophe unit and lower than expected claims emergence in the Company’s specialty reinsurance unit.

Insurance Segment

Gross premiums written for the Company’s Insurance segment decreased $13.3 million, or 20.4%, to $51.9 million in the first quarter of 2010, compared to $65.1 million in the first quarter of 2009. The decrease was primarily due to the Company’s prior decisions to terminate several program manager relationships and a commercial property quota share contract as a result of softening market conditions, resulting in reduced commercial property and personal lines property gross premiums written. Gross premiums written in the Company’s Insurance segment can fluctuate, perhaps significantly, between quarters and between years based on several factors, including, without limitation, the timing of the inception or cessation of new program managers and quota share reinsurance contracts, including whether or not the Company has portfolio transfers in, or portfolio transfers out, of quota share reinsurance contracts of in-force books of business.

The Insurance segment generated $5.3 million of underwriting income and had a combined ratio of 81.1% in the first quarter of 2010, compared to an underwriting loss of $30.1 million and a combined ratio of 139.7% in the first quarter of 2009. The increase in underwriting income and decrease in the combined ratio in the first quarter of 2010, compared to the first quarter of 2009, were primarily due to a decrease in net claims and claim expenses as a result of favorable development on prior years reserves of $56.5 million, compared to unfavorable development on prior years reserves of $32.0 million in the first quarter of 2009, and a decrease in current accident year net claims and claim expenses of $3.6 million, partially offset by a $47.7 million decrease in net premiums earned and a $13.8 million increase in operational expenses. The increase in operational expenses was due in part to a $6.8 million charge for impairing software related assets and recognizing severance benefits related to the Company’s decision in the first quarter of 2010 to discontinue a new start-up initiative which was under development in 2009 and had yet to commence operations.

During the first quarter of 2010, the Company settled the majority of its outstanding claims associated with the 2009 crop year for its crop insurance business. Due primarily to better than expected yields on late harvested crops for the 2009 crop year, the Company experienced significantly better than expected results on the settlement of its crop claims and, as a result, the Company experienced $44.1 million of favorable development associated with its crop insurance business in the first quarter of 2010. This resulted in a net underwriting gain of $19.5 million in the first quarter of 2010 and decreased the Insurance segment’s combined ratio by 45.7 percentage points, after taking into consideration the fact that $24.7 million of the favorable development was ceded to the Federal Crop Insurance Corporation (“FCIC”), as discussed below. The $19.5 million underwriting gain includes $15.3 million and $4.2 million associated with the Company’s multi-peril crop insurance and crop hail lines of business, respectively. The multi-peril crop insurance is written through the FCIC. The FCIC sponsors an insurance program that provides reinsurance to participating insurers, including the Company, for multi-peril crop insurance. The terms of the reinsurance agreement with the FCIC allow the Company to retain only a portion of any underwriting gain or loss experienced on multi-peril crop insurance policies issued in each state. The Company records the underwriting gain that is not retained as additional ceded premiums written and earned which totaled $24.7 million in the first quarter of 2010, and offsets a significant portion of the $44.1 million of favorable development on prior year reserves associated with the crop business in the first quarter of 2010. These components are summarized below:

4

The unfavorable loss reserve development in the first quarter of 2009 of $32.0 million was primarily due to a $27.3 million increase in prior year losses in the Company’s crop insurance line of business related to the 2008 crop year due to an increase in the severity of reported losses incurred during 2008 and reported during the first quarter of 2009. The net impact of this unfavorable development, after considering corresponding changes in net earned premium and related acquisition costs for the 2008 crop year, was a reduction in underwriting income of $25.8 million and an increase in the Company’s combined ratio of 33.7 percentage points.

Investments

Returns on the Company’s investment portfolio increased in the first quarter of 2010 compared to the first quarter of 2009, primarily due to higher total returns on the Company’s fixed maturity investments and hedge funds and private equity investments as discussed in more detail below. The Company’s total investment result, which includes the sum of net investment income, net realized and unrealized gains on fixed maturity investments and net other-than-temporary impairments, was $107.1 million in the first quarter of 2010, compared to $39.8 million in the first quarter of 2009, an increase of $67.3 million. The Company’s total investment result for the first quarter of 2010 continued to benefit from tightening credit spreads, improved economic conditions and increased average invested assets, and partially offset by a modest increase in interest rates.

Net investment income was $67.2 million in the first quarter of 2010, compared to $42.1 million in the first quarter of 2009. The $25.1 million increase in net investment income was principally driven by a $37.3 million increase from the Company’s hedge fund and private equity investments and partially offset by a $10.5 million decrease in net investment income from the Company’s fixed maturity investments, principally due to lower yields on these investments. The Company’s hedge fund, private equity and other investments are accounted for at fair value with the change in fair value recorded in net investment income, which included net unrealized gains of $24.9 million in the first quarter of 2010, compared to net unrealized losses of $17.0 million in the first quarter of 2009.

Net realized and unrealized gains on fixed maturity investments were $48.6 million in the first quarter of 2010, compared to $22.1 million in the first quarter of 2009, an increase of $26.5 million. During the fourth quarter of 2009, the Company started designating, upon acquisition, certain fixed maturity investments as trading, rather than available for sale, and as a result, $4.9 million of net unrealized gains on these securities are recorded in net realized and unrealized gains on fixed maturity investments in the Company’s consolidated statements of operations in the first quarter of 2010 rather than in accumulated other comprehensive income in shareholders’ equity. Net other-than-temporary impairments recognized in earnings were $33 thousand in the first quarter of 2010, compared to $19.0 million for the first quarter of 2009. The significant decrease in net other-than-temporary impairments is due to the combination of improved economic conditions in the first quarter of 2010, compared to the first quarter of 2009, the adoption of new authoritative accounting guidance related to the recognition and presentation of other-than-temporary impairments during the second quarter of 2009, and the transition of a significant portion of the portfolio from available for sale to trading . The Company’s gross unrealized losses on available for sale fixed maturity investments included in accumulated other comprehensive income was $3.5 million at March 31, 2010.

Comments on Regulation G

In addition to the GAAP financial measures set forth in this Press Release, the Company has included certain non-GAAP financial measures in this Press Release within the meaning of Regulation G. The Company has provided these financial measurements in previous investor communications and the Company’s management believes that these measurements are important to investors and other interested persons, and that investors and such other persons benefit from having a consistent basis for comparison between quarters and for the comparison with other companies within the industry. These measures may not, however, be comparable to similarly titled measures used by companies outside of the insurance industry. Investors are cautioned not to place undue reliance on these non-GAAP measures in assessing the Company’s overall financial performance.

The Company uses “operating income available to RenaissanceRe common shareholders” as a measure to evaluate the underlying fundamentals of its operations and believes it to be a useful measure of its corporate performance. “Operating income available to RenaissanceRe common shareholders” as used herein differs from “net income available to RenaissanceRe common shareholders,” which the Company believes is the most directly comparable GAAP measure, by the exclusion of net realized and unrealized gains and losses on fixed maturity investments and net other-than-temporary impairments. The Company’s management believes that “operating income available to RenaissanceRe common shareholders” is useful to investors because it more accurately measures and predicts the Company’s results of operations by removing the variability arising from fluctuations in the Company’s fixed maturity investment portfolio. The Company also uses “operating income available to RenaissanceRe common shareholders” to calculate “operating income available to RenaissanceRe common shareholders per common share – diluted” and “operating return on average common equity – annualized”. The following is a reconciliation of: 1) net income available to RenaissanceRe common shareholders to operating income available to RenaissanceRe common shareholders; 2) net income available to RenaissanceRe common shareholders per common share – diluted to operating income available to RenaissanceRe common shareholders per common share – diluted; and 3) return on average common equity – annualized to operating return on average common equity – annualized:

The Company has also included in this Press Release “managed catastrophe premiums” and “managed specialty premiums”. “Managed catastrophe premiums” is defined as gross catastrophe premiums written by Renaissance Reinsurance and its related joint ventures, excluding catastrophe premiums assumed from the Company’s Insurance segment. “Managed catastrophe premiums” differ from total catastrophe unit premiums, which the

13

Company believes is the most directly comparable GAAP measure, due to the inclusion of catastrophe premiums written on behalf of the Company’s joint venture Top Layer Re, which is accounted for under the equity method of accounting, the inclusion of catastrophe premiums written on behalf of the Company’s Lloyd’s unit, and the exclusion of catastrophe premiums assumed from the Company’s Insurance segment. “Managed specialty premiums” is defined as gross specialty premiums written by Renaissance Reinsurance, DaVinci and the Company’s Lloyd’s unit. “Managed specialty premiums” differ from total specialty unit premiums, which the Company believes is the most directly comparable GAAP measure, due to the inclusion of specialty premiums written on behalf of the Company’s Lloyd’s unit. The Company’s management believes “managed catastrophe premiums” and “managed specialty premiums” are useful to investors and other interested parties because they provide a measure of total catastrophe or specialty reinsurance premiums, as applicable, assumed by the Company through its consolidated subsidiaries and related joint ventures.
