RENAISSANCERE HOLDINGS LTD

SUMMARY OF RESULTS OF OPERATIONS

Below is a discussion of the results of operations for the second quarter of 2024, compared to the second quarter of 2023.

Net income available to RenaissanceRe common shareholders was $495.0 million in the second quarter of 2024, compared to $191.0 million in the second quarter of 2023, an increase of $304.0 million. As a result of our net income available to RenaissanceRe common shareholders in the second quarter of 2024, we generated an annualized return on average common equity of 21.4%, and our book value per common share increased from $165.20 at December 31, 2023 to $179.87 at June 30, 2024, a 5.5% increase, after considering the change in accumulated dividends paid to our common shareholders.

The most significant items affecting our financial performance during the second quarter of 2024, on a comparative basis to the second quarter of 2023, include:

•Underwriting Results - we generated underwriting income of $479.3 million and had a combined ratio of 81.1% in the second quarter of 2024, compared to underwriting income of $351.0 million and a combined ratio of 80.3% in the second quarter of 2023. Our underwriting income in the second quarter of 2024 was comprised of our Property segment, which generated underwriting income of $451.7 million and had a combined ratio of 53.9%, and our Casualty and Specialty segment, which generated underwriting income of $27.6 million and had a combined ratio of 98.2%. In comparison, our underwriting income in the second quarter of 2023 was comprised of our Property segment, which generated underwriting income of $281.0 million and had a combined ratio of 63.0%, and our Casualty and Specialty segment, which generated underwriting income of $70.0 million and had a combined ratio of 93.2%;

•Gross Premiums Written - our gross premiums written increased by $773.9 million, or 29.2%, to $3.4 billion, in the second quarter of 2024, compared to the second quarter of 2023. This was comprised of an increase of $423.4 million in our Casualty and Specialty segment and $350.5 million in our Property segment, both primarily driven by the renewal of business acquired in the Validus Acquisition, in conjunction with the retention of legacy lines;

•Investment Results - our total investment result, which includes net investment income and net realized and unrealized gains (losses) on investments, was income of $283.3 million in the second quarter of 2024, compared to $69.9 million in the second quarter of 2023, an increase of $213.4 million. The primary drivers of the higher total investment result were an increase in net investment income of $118.2 million due to a combination of higher average invested assets, primarily resulting from the Validus Acquisition, and higher yielding assets, as well as lower net realized and unrealized losses on investments in the second quarter of 2024 compared to the second quarter of 2023. Net realized and unrealized losses on investments decreased $95.2 million as a result of lower net realized and unrealized losses on fixed maturity investments compared to the comparative quarter, primarily due to generally lower increases in interest rates in the second quarter of 2024 compared to the second quarter of 2023;

•Net Income Attributable to Redeemable Noncontrolling Interests- our net income attributable to redeemable noncontrolling interests was $224.7 million in the second quarter of 2024, compared to $174.9 million in the second quarter of 2023. The higher net income attributable to redeemable noncontrolling interests in the second quarter of 2024 was primarily driven by improved underwriting results generated by DaVinci and Vermeer, and higher net investment income resulting from higher average invested assets and higher yielding assets within the investment portfolios of our joint ventures and managed funds; and

•Impact of Large Loss Events- we had a net negative impact on net income available to RenaissanceRe common shareholders of $50.9 million resulting from the Q2 2024 Large Loss Events. This compares to a net negative impact on net income available to RenaissanceRe common shareholders of $44.6 million resulting from the 2023 Large Loss Events.

Net Negative Impact

Net negative impact on underwriting result includes the sum of (1) net claims and claim expenses incurred, (2) assumed and ceded reinstatement premiums earned and (3) earned and lost profit commissions. Net negative impact on net income (loss) available (attributable) to RenaissanceRe common shareholders is the sum of (1) net negative impact on underwriting result and (2) redeemable noncontrolling interest, both before consideration of any related income tax benefit (expense).

Our estimates of net negative impact are based on a review of our potential exposures, preliminary discussions with certain counterparties and actuarial modeling techniques. Our actual net negative impact, both individually and in the aggregate, may vary from these estimates, perhaps materially. Changes in these estimates will be recorded in the period in which they occur.

Meaningful uncertainty remains regarding the estimates and the nature and extent of the losses from these catastrophe events, driven by the magnitude and recent nature of each event, the geographic areas impacted by the events, relatively limited claims data received to date, the contingent nature of business interruption and other exposures, potential uncertainties relating to reinsurance recoveries and other factors inherent in loss estimation, among other things.

The financial data below provides additional information detailing the net negative impact of the 2023 Large Loss Events on our consolidated financial statements in the second quarter of 2023.

(1)“2023 Large Loss Events” includes the earthquakes which impacted southern and central Turkey in February 2023, Cyclone Gabrielle which impacted northern New Zealand, the flooding that impacted northern New Zealand in January and February 2023, and various wind and thunderstorm events which impacted states in both the Southern and Midwest U.S. during March 2023 (“Q1 2023 Large Loss Events”), and a series of large, severe weather events that impacted Texas and other southern and central U.S. states in June 2023. Net negative impact on net income (loss) available (attributable) to RenaissanceRe common shareholders for the three months ended June 30, 2023 includes an increase of approximately $20.0 million in the net negative impact of the Q1 2023 Large Loss Events during the second quarter.

Underwriting Results by Segment

Below is a summary of the underwriting results and ratios for our Property segment:

Property Gross Premiums Written

In the second quarter of 2024, our Property segment gross premiums written increased by $350.5 million, or 25.0%, to $1.8 billion, compared to the second quarter of 2023.

Gross premiums written in the catastrophe class of business were $1.3 billion in the second quarter of 2024, an increase of $262.8 million, or 26.2%, compared to the second quarter of 2023. This increase was principally driven by the renewal of business acquired in the Validus Acquisition, in conjunction with the retention of legacy lines, at the June 1, 2024 renewal.

Gross premiums written in the other property class of business were $488.5 million in the second quarter of 2024, an increase of $87.7 million, or 21.9%, compared to the second quarter of 2023. The increase in gross premiums written in the other property class of business was principally due to the renewal of business acquired in the Validus Acquisition and organic growth in both our catastrophe and non-catastrophe exposed business within other property.

Property Ceded Premiums Written

Due to the potential volatility of the reinsurance contracts which we sell, we purchase reinsurance to reduce our exposure to large losses and to help manage our risk portfolio. To the extent that appropriately priced coverage is available, we anticipate continued use of retrocessional reinsurance to reduce the impact of large losses on our financial results and to manage our portfolio of risk; however, the buying of ceded reinsurance in our Property segment is based on market opportunities and is not based on placing a specific reinsurance program each year. In addition, we may utilize insurance-linked securities for purchases of retrocessional reinsurance if we find the pricing and terms of such coverages attractive.

Ceded premiums written in our Property segment were $394.4 million in the second quarter of 2024, an increase of $136.5 million, or 52.9%, compared to the second quarter of 2023. The increase in ceded purchases is driven by the increase in protection purchased due to the growth in our assumed portfolio resulting from the Validus Acquisition and organic growth, as well as increased utilization of Upsilon, as part of our gross-to-net strategy.

Property Net Premiums Written

Net premiums written in our Property segment were $1.4 billion in the second quarter of 2024, an increase of $214.0 million, or 18.7%, compared to the second quarter of 2023, consistent with the changes in gross premiums written discussed above, partially offset by an increase in ceded premiums written as part of our gross-to-net strategy.

Property Underwriting Results

Our Property segment generated underwriting income of $451.7 million in the second quarter of 2024, compared to $281.0 million in the second quarter of 2023. In the second quarter of 2024, our Property segment generated a net claims and claim expense ratio of 27.9%, an underwriting expense ratio of 26.0% and a combined ratio of 53.9%, compared to 37.2%, 25.8% and 63.0%, respectively, in the second quarter of 2023.

Impacting the underwriting result and combined ratio in the second quarter of 2024 were the Q2 2024 Large Loss Events, which resulted in a net negative impact on the Property segment underwriting result of $63.0 million and added 7.0 percentage points to the Property segment combined ratio, reflecting impacts in both the catastrophe and other property class of business. Impacting the underwriting result and combined ratio in the second quarter of 2023 were the 2023 Large Loss Events, which resulted in a net negative impact on the Property segment underwriting result of $68.5 million and added 10.8 percentage points to the Property segment combined ratio, reflecting impacts in both the catastrophe and other property classes of business.

The net claims and claim expense ratio in the second quarter of 2024 of 27.9% was comprised of a current accident year net claims and claim expense ratio of 36.5% and 8.6 percentage points of net favorable development of prior accident years, primarily in the catastrophe class of business in the 2021 to 2023 accident years. In comparison, the second quarter of 2023 had a net claims and claim expense ratio of 37.2%, comprised of a current accident year net claims and claim expense ratio of 41.3% and 4.1 percentage points of net favorable development of prior accident years.

The current accident year net claims and claim expense ratio for the Property segment, which decreased by 4.8 percentage points, included a 7.7 percentage point impact from the Q2 2024 Large Loss Events in the second quarter of 2024 compared to 11.5 percentage points from the 2023 Large Loss Events in the second quarter of 2023. In the catastrophe class of business, a 14.3 percentage point improvement was primarily due to the lower impact from large loss events, with the Q2 2024 Large Loss Events adding 9.6 percentage points compared to the 2023 Large Loss Events which added 18.5 percentage points in the second quarter of 2023. In the other property class of business, the 10.2 percentage point increase was primarily driven by a series of individual risk losses which added 4.7 percentage points in the second quarter of 2024. In addition, the Q2 2024 Large Loss Events added 5.5 percentage points, compared to the 2023 Large Loss Events which added 3.8 percentage points in the second quarter of 2023.

See “Note 6. Reserve for Claims and Claim Expenses” in our “Notes to the Consolidated Financial Statements” for additional information related to the prior year development of net claims and claim expenses.

The underwriting expense ratio increased 0.2 percentage points, largely driven by a 0.6 percentage point increase in acquisition expenses from purchase accounting adjustments relating to the Validus Acquisition, which added 1.8 percentage points to the acquisition expense ratio in the second quarter of 2024, partially offset by changes in the mix of business as a result of the continued relative growth in the catastrophe class of business, which has a lower acquisition expense ratio than the other property class of business. This increase in the acquisition expense ratio was partially offset by a 0.4 percentage point decrease in the operating expense ratio, primarily due to an increase in net premiums earned.

In the second quarter of 2024, Property segment underwriting income was reduced by total purchase accounting adjustments of $21.9 million, which added 2.2 percentage points to the Property segment combined ratio.

Below is a summary of the underwriting results and ratios for our Casualty and Specialty segment:

Casualty and Specialty Gross Premiums Written

In the second quarter of 2024, our Casualty and Specialty segment gross premiums written increased by $423.4 million, or 33.9%, to $1.7 billion, compared to the second quarter of 2023. This increase was primarily driven by the renewal of business acquired in the Validus Acquisition, and is principally reflected in the general casualty and other specialty classes of business, which grew by $255.4 million and $247.8 million, respectively, compared to the second quarter of 2023. This increase also reflects organic growth of legacy lines, particularly within the other specialty class of business. Partly offsetting this growth were reductions to premium estimates on business underwritten in prior years. These changes in premium estimates occurred across all classes of business, but principally in the professional liability class of business which decreased $94.2 million in the second quarter of 2024 compared to the second quarter of 2023 and is largely driven by reported premiums and revised ceding company estimates.

Casualty and Specialty Ceded Premiums Written

We purchase reinsurance to reduce our exposure to large losses and to help manage our risk portfolio. To the extent that appropriately priced coverage is available, we anticipate continued use of retrocessional reinsurance to reduce the impact of large losses on our financial results and to manage our portfolio of risk. As in our Property segment, the buying of ceded reinsurance in our Casualty and Specialty segment is based on market opportunities and is not based on placing a specific reinsurance program each year.

Ceded premiums written in our Casualty and Specialty segment decreased by $5.3 million, to $192.5 million, in the second quarter of 2024, compared to $197.9 million in the second quarter of 2023, driven by a decrease in amount of quota share retrocessional coverage purchased.

Casualty and Specialty Net Premiums Written

Net premiums written in our Casualty and Specialty segment increased by $428.7 million, or 40.8%, to $1.5 billion, in the second quarter of 2024, compared to $1.1 billion in the second quarter of 2023, consistent with the changes in gross premiums written and quota share retrocessional coverage purchased as discussed above.

Casualty and Specialty Underwriting Results

Our Casualty and Specialty segment generated underwriting income of $27.6 million in the second quarter of 2024, compared to underwriting income of $70.0 million in the second quarter of 2023. In the second quarter of 2024, our Casualty and Specialty segment generated a net claims and claim expense ratio of 66.4%, an underwriting expense ratio of 31.8% and a combined ratio of 98.2%, compared to 63.2%, 30.0% and 93.2%, respectively, in the second quarter of 2023.

The increase in the Casualty and Specialty segment combined ratio in the second quarter of 2024 by 5.0 percentage points to 98.2% was primarily driven by the current accident year net claims and claim expense ratio which increased 4.6 percentage points, principally as a result of two specific losses within the structured credit and transactional liability lines of business which added 3.4 percentage points. During the second quarter of 2024, our Casualty and Specialty segment also experienced net favorable development on prior accident years net claims and claim expenses of $23.9 million or 1.5 percentage points, compared to $0.5 million or 0.1 percentage points during the second quarter of 2023. The increase in net favorable development was principally driven by reported losses generally coming in lower than expected on attritional net claims and claim expenses from the other specialty, credit and professional liability classes of business, partially offset by the impact of purchase accounting adjustments relating to the Validus Acquisition.

See “Note 6. Reserve for Claims and Claim Expenses” in our “Notes to the Consolidated Financial Statements” for additional information related to the prior year development of net claims and claim expenses.

The underwriting expense ratio increased 1.8 percentage points driven by a 1.7 percentage point increase in the acquisition expense ratio from the impact of purchase accounting adjustments.

In the second quarter of 2024, Casualty and Specialty segment underwriting income was reduced by total purchase accounting adjustments of $41.0 million, which added 2.6 percentage points to the Casualty and Specialty segment combined ratio.

Our relative mix of business between proportional business and excess of loss business has fluctuated in the past and will likely continue to do so in the future. Proportional business, which represents the majority of our Casualty and Specialty segment business, typically has a higher expense ratio and tends to be exposed to more attritional and frequent losses, while being subject to less expected severity compared to traditional excess of loss business.

The table above shows total fee income earned through third-party capital management activities, including various joint ventures, managed funds and certain structured retrocession agreements to which we are a party. Performance fees are based on the performance of the individual vehicles or products and may be zero or negative in a particular period if, for example, large losses occur, which can potentially result in no performance fees or the reversal of previously accrued performance fees. Joint ventures include DaVinci, Top Layer, Vermeer, and Fontana. Managed funds include Upsilon Fund and Medici, as well as fee income earned by AlphaCat Managers, which was acquired as part of the Validus Acquisition. Structured reinsurance products and other includes certain reinsurance contracts and certain other vehicles through which we transfer risk to third-party capital.

In the second quarter of 2024, total fee income earned through third-party capital management activities increased $27.4 million, to $84.1 million, compared to $56.7 million in the second quarter of 2023, due to higher management and performance fee income.

Management fee income increased $11.9 million compared to the second quarter of 2023, driven by increased capital managed at DaVinci and Fontana, as well as the addition of fees earned by AlphaCat Managers.

Performance fee income increased $15.5 million compared to the second quarter of 2023, driven by improved underwriting results and favorable development on prior year events, primarily in DaVinci and in certain structured reinsurance products.

The fees earned through third-party capital management activities are principally recorded through redeemable noncontrolling interest, or as an increase to underwriting income through a decrease in operational expenses or acquisition expenses. Below is a summary of the impact of fee income on the applicable financial statement line items.

(1)Reflects total fee income earned through third-party capital management activities recorded through underwriting income (loss) as a decrease (increase) to operational expenses or acquisition expenses. The $13.0 million includes $12.9 million of management fee income, recorded as a reduction to operational expenses and $0.1 million of performance fee income recorded as a reduction to acquisition expenses (2023 - $8.2 million, $11.2 million and an increase of $3.0 million, respectively).

In addition to the $13.0 million of fee income earned through our third-party capital management activities that was recorded through underwriting income (loss), as detailed above, we also earn additional fee income on certain other underwriting-related activities. These fees, in the aggregate, are recorded as a reduction to operational expenses or acquisition expenses, as applicable. The total fees recorded through underwriting income (loss) are detailed in the table below.

(1)The $31.0 million includes $25.9 million of management fee income, recorded as a reduction to operational expenses and $5.1 million of performance fee income recorded as a reduction to acquisition expenses (2023 - $36.8 million, $31.7 million and $5.1 million, respectively).

Net investment income was $410.8 million in the second quarter of 2024, compared to $292.7 million in the second quarter of 2023, an increase of $118.2 million. This increase was primarily driven by higher average invested assets, primarily resulting from the Validus Acquisition, and higher yielding assets in the fixed maturity and short term portfolios.

(1)Net realized and unrealized gains (losses) on investment-related derivatives includes fixed maturity investments related derivatives (interest rate futures and credit default swaps), equity investments related derivatives (equity futures) and commodity investments related derivatives (commodity futures and commodity options). See “Note 13. Derivative Instruments” in our “Notes to Consolidated Financial Statements” for additional information.

We structure our investment portfolio to emphasize the preservation of capital and the availability of liquidity to meet our claims obligations, to be well diversified across market sectors, and to generate relatively attractive returns on a risk-adjusted basis over time. A large majority of our investments are invested in the fixed income markets and, therefore, our realized and unrealized holding gains and losses on investments are highly correlated to fluctuations in interest rates. As interest rates decline, we will tend to have realized and unrealized gains from our investment portfolio, and as interest rates rise, we will tend to have realized and unrealized losses from our investment portfolio.

Net realized and unrealized losses on investments were $127.6 million in the second quarter of 2024, compared to net realized and unrealized losses of $222.8 million in the second quarter of 2023. Principally impacting our net realized and unrealized losses on investments in the second quarter of 2024 were:

•net realized and unrealized losses on our fixed maturity investments trading portfolio of $90.7 million in the second quarter of 2024, compared to net realized and unrealized losses of $214.0 million in the second quarter of 2023, driven by generally lower increases in interest rates in the second quarter of 2024 compared to the second quarter of 2023;

•net realized and unrealized gains on investment-related derivatives of $10.4 million in the second quarter of 2024, driven by net gains on commodity futures as a result of commodity price movements, compared to net realized and unrealized losses of $65.1 million in the second quarter of 2023, driven by net losses on interest rate futures and credit default swaps due to interest rate increases and tightening credit spreads; and

•net realized and unrealized losses on catastrophe bonds of $34.1 million in the second quarter of 2024 compared to net realized and unrealized gains of $38.2 million in the second quarter of 2023, which is reflective of changes in risk spreads in the wider catastrophe bond market.

Net Foreign Exchange Gains (Losses)

Our functional currency is the U.S. dollar. We routinely write a portion of our business in currencies other than U.S. dollars and invest a portion of our cash and investment portfolio in those currencies. We are primarily impacted by foreign currency exposures associated with our underwriting operations and our investment portfolio, and may, from time to time, enter into foreign currency forward and option contracts to minimize the effect of fluctuating foreign currencies on the value of non-U.S. dollar denominated assets and liabilities.

In the second quarter of 2024, net foreign exchange losses were $8.8 million compared to $13.5 million in the second quarter of 2023. The net foreign exchange losses in the second quarter of 2024 and 2023 were primarily driven by losses attributable to third-party investors in Medici which are allocated through net income (loss) attributable to redeemable noncontrolling interest, in addition to the impact of certain foreign exchange exposures related to our underwriting activities.

Refer to “Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk” in our Form 10-K for the year ended December 31, 2023 for additional information related to our exposure to foreign currency risk and “Note 13. Derivative Instruments” in our “Notes to the Consolidated Financial Statements” for additional information related to foreign currency forward and option contracts we have entered into.

Equity in Earnings (Losses) of Other Ventures

Equity in earnings of other ventures represents our pro-rata share of the net income from our investments in a select group of insurance and insurance-related companies, including the Tower Hill Companies and Top Layer. Except for Top Layer, which is recorded on a current quarter basis, equity in earnings of other ventures is recorded one quarter in arrears. The carrying value of these investments on our consolidated balance sheets, individually or in the aggregate, may differ from the realized value we may ultimately attain, perhaps significantly so.

Earnings from our investments in other ventures were $12.6 million in the second quarter of 2024, compared to $7.7 million in the second quarter of 2023, an increase of $4.9 million. The increase was principally driven by increased profitability of our equity investments during the second quarter of 2024, as certain insurance and insurance-related companies reported higher net income in the second quarter of 2024 compared to the second quarter of 2023, as a result of negative fair value movements within their underlying investment portfolios in the prior period.

Corporate Expenses

Corporate expenses include certain executive, director, legal and consulting expenses, costs for research and development, and other miscellaneous costs, including those associated with operating as a publicly traded company, as well as costs incurred in connection with the Validus Acquisition. From time to time, we may revise the allocation of certain expenses between corporate and operational expenses to better reflect the characteristic of the underlying expense.

Corporate expenses were $35.2 million in the second quarter of 2024, compared to $23.4 million in the second quarter of 2023, an increase of $11.8 million, which was primarily driven by $17.3 million of expenses associated with the Validus Acquisition, compared to $11.3 million in the comparative quarter. We expect to incur additional costs and expenses associated with the Validus Acquisition. These additional non-recurring costs may be significant, and it is possible that our ultimate costs will exceed our current estimates.

Income Tax Benefit (Expense)

We recognized an income tax benefit of $20.8 million in the second quarter of 2024, compared to an income tax expense of $5.9 million in the second quarter of 2023. The decrease in income tax expense was primarily driven by a $33.7 million deferred tax benefit resulting from the merger of RREAG and Validus Switzerland, partially offset by higher income tax expense as a result of increased underwriting and net investment income in the second quarter of 2024 compared to the second quarter of 2023.

Net Income (Loss) Attributable to Redeemable Noncontrolling Interests

Our net income (loss) attributable to redeemable noncontrolling interests was $224.7 million in the second quarter of 2024, compared to $174.9 million in the second quarter of 2023, an increase of $49.8 million. This increase was primarily due to the following:

•DaVinci, which had an increase in net income in the second quarter of 2024 compared to the second quarter of 2023, primarily resulting from strong underwriting results and an increase in total investment result;

•Vermeer, which had an increase in net income in the second quarter of 2024 compared to the second quarter of 2023, primarily resulting from strong underwriting results; and

•Fontana, which had an increase in net income in the second quarter of 2024 compared to the second quarter of 2023, primarily resulting from improved underwriting results; partially offset by

•Medici, which had a decrease in net income in the second quarter of 2024 compared to the second quarter of 2023, primarily resulting from a decrease in net realized and unrealized gains on catastrophe bonds, and partially offset by a decrease in net foreign exchange losses.

Refer to “Note 8. Noncontrolling Interests” in our “Notes to the Consolidated Financial Statements” for additional information regarding our redeemable noncontrolling interests.

SUMMARY OF RESULTS OF OPERATIONS

Below is a discussion of the results of operations for the six months ended June 30, 2024, compared to the six months ended June 30, 2023.

Net income available to RenaissanceRe common shareholders was $859.8 million in the six months ended June 30, 2024, compared to $755.1 million in the six months ended June 30, 2023. As a result of our net income available to RenaissanceRe common shareholders in the six months ended June 30, 2024, we generated an annualized return on average common equity of 19.0% and our book value per common share increased from $165.20 at December 31, 2023 to $179.87 at June 30, 2024, a 9.4% increase, after considering the change in accumulated dividends paid to our common shareholders.

The most significant items affecting our financial performance during the six months ended June 30, 2024, on a comparative basis to the six months ended June 30, 2023, include:

•Underwriting Results -we generated underwriting income of $1.0 billion and had a combined ratio of 79.5% in the six months ended June 30, 2024, compared to underwriting income of $720.6 million and a combined ratio of 79.2% in the six months ended June 30, 2023. Our underwriting income in the six months ended June 30, 2024 was comprised of our Property segment, which generated underwriting income of $986.1 million and had a combined ratio of 48.6%, and our Casualty and Specialty segment, which generated underwriting income of $33.9 million and had a combined ratio of 98.9%. In comparison, our underwriting income in the six months ended June 30, 2023 was comprised of our Property segment, which generated underwriting income of $579.7 million and had a combined ratio of 59.9%, and our Casualty and Specialty segment, which generated underwriting income of $140.9 million and had a combined ratio of 93.0%;

Included in our underwriting results in the six months ended June 30, 2024 was the impact of the 2024 Large Loss Events, which resulted in a net negative impact on the underwriting result of $142.5 million and added 2.9 percentage points to the consolidated combined ratio. In comparison, our underwriting results in the six months ended June 30, 2023 were impacted by the 2023 Large Loss Events, which resulted in a net negative impact on the underwriting result of $147.6 million and added 4.5 percentage points to the combined ratio, all within our Property segment;

•Gross Premiums Written - our gross premiums written increased by $2.0 billion, or 36.3%, to $7.4 billion, in the six months ended June 30, 2024, compared to the six months ended June 30, 2023. This was comprised of an increase of $1.0 billion in our Casualty and Specialty segment and an increase of $936.2 million in our Property segment, both primarily driven by the renewal of business acquired in the Validus Acquisition, in conjunction with the retention of legacy lines;

•Investment Results - our total investment result, which includes the sum of net investment income and net realized and unrealized gains (losses) on investments, was income of $460.4 million in the six months ended June 30, 2024, compared to $603.7 million in the six months ended June 30, 2023, a decrease of $143.3 million. The primary drivers of the lower total investment result was a decrease of $397.9 million in net realized and unrealized gains on investments, partially offset by an increase in net investment income of $254.6 million. The change in net realized and unrealized gains (losses) was due to increased losses on the fixed maturity trading portfolio of $286.1 million, driven by generally higher increases in medium and long term interest rates during 2024 compared to 2023, as well as losses of $77.5 million on catastrophe bonds, due to changes in risk spreads in the wider catastrophe bond market. The increase in net investment income was driven by higher average invested assets, primarily resulting from the Validus Acquisition, and higher yielding assets;

•Net Income Attributable to Redeemable Noncontrolling Interests- our net income attributable to redeemable noncontrolling interests was $469.6 million in the six months ended June 30, 2024, compared to $442.3 million in the six months ended June 30, 2023. Net income attributable to redeemable noncontrolling interests in the six months ended June 30, 2024 was primarily driven by underwriting income generated by DaVinci, Vermeer and Medici, and net investment income resulting from higher average invested assets and higher yielding assets within the investment portfolios of our joint ventures and managed funds;

•Impact of Large Loss Events - we had a net negative impact on net income available to RenaissanceRe common shareholders of $105.2 million resulting from the 2024 Large Loss Events. This compares to a net negative impact on net income available to RenaissanceRe common shareholders of $98.1 million resulting from the 2023 Large Loss Events.

Underwriting Results by Segment

Below is a summary of the underwriting results and ratios for our Property segment:

Property Gross Premiums Written

In the six months ended June 30, 2024, our Property segment gross premiums written increased by $936.2 million, or 34.6%, to $3.6 billion, compared to $2.7 billion in the six months ended June 30, 2023.

Gross premiums written in the catastrophe class of business were $2.6 billion in the six months ended June 30, 2024, an increase of $675.3 million, or 35.0%, compared to the six months ended June 30, 2023. This increase was principally driven by the renewal of business acquired in the Validus Acquisition, in conjunction with the retention of legacy lines, during the six months ended June 30, 2024.

Gross premiums written in the other property class of business were $1.0 billion in the six months ended June 30, 2024, an increase of $260.9 million, or 33.6%, compared to the six months ended June 30, 2023. The increase in gross premiums written in the other property class of business was principally due to the renewal of business acquired in the Validus Acquisition and organic growth in both our catastrophe and non-catastrophe exposed business.

Property Ceded Premiums Written

Ceded premiums written in our Property segment increased 63.5%, to $886.7 million, in the six months ended June 30, 2024, compared to $542.3 million in the six months ended June 30, 2023. The increase in ceded purchases reflects our larger portfolio resulting from the Validus Acquisition and organic growth, as well as increased utilization of Upsilon, as part of our gross-to-net strategy.

Property Net Premiums Written

Net premiums written in our Property segment were $2.8 billion in the six months ended June 30, 2024, an increase of $591.8 million, or 27.3%, compared to the six months ended June 30, 2023, consistent with the changes in gross premiums written discussed above, partially offset by an increase in ceded premiums written as part of our gross-to-net strategy.

Property Underwriting Results

Our Property segment generated underwriting income of $986.1 million in the six months ended June 30, 2024, compared to $579.7 million in the six months ended June 30, 2023, an increase in underwriting income of $406.4 million. In the six months ended June 30, 2024, our Property segment generated a net claims and claim expense ratio of 22.3%, an underwriting expense ratio of 26.3% and a combined ratio of 48.6%, compared to 32.5%, 27.4% and 59.9%, respectively, in the six months ended June 30, 2023.

Impacting the Property segment underwriting result and combined ratio in the six months ended June 30, 2024 were the 2024 Large Loss Events, which resulted in a net negative impact on the Property segment underwriting result of $81.5 million and added 4.6 percentage points to its combined ratio, reflecting impacts in both the catastrophe and other property class of business. In comparison, the six months ended June 30, 2023 was impacted by the 2023 Large Loss Events, which resulted in a net negative impact on the Property segment underwriting result of $147.6 million and added 11.3 percentage points to its combined ratio.

The net claims and claim expense ratio of 22.3% was comprised of a current accident year net claims and claim expense ratio of 31.6% and 9.3 percentage points of net favorable development on prior accident years, primarily in the catastrophe class of business in the 2021 to 2023 accident years. In comparison, the six months ended June 30, 2023 had a net claims and claim expense ratio of 32.5%, comprised of a current accident year net claims and claim expense ratio of 40.3% and 7.8 percentage points of net favorable development on prior accident years. The decrease of 8.7 percentage points in the current accident year net claims and claim expense ratio is primarily as a result of a lower impact from the 2024 Large Loss Events which contributed 4.8 percentage points to the current accident year net claims and claim expense ratio in the six months ended June 30, 2024, compared to 11.6 percentage points in the six months ended June 30, 2023.

See “Note 6. Reserve for Claims and Claim Expenses” in our “Notes to the Consolidated Financial Statements” for additional information related to the development of prior accident years net claims and claim expenses.

The underwriting expense ratio decreased 1.1 percentage points, largely driven by a 1.0 percentage point decrease in the operating expense ratio primarily due to an increase in net premiums earned as well as continued relative growth in the catastrophe class of business, which has a lower acquisition expense ratio than the other property class of business, partially offset by the increase in acquisition expenses from purchase accounting adjustments relating to the Validus Acquisition, which added 2.0 percentage points to the acquisition expense ratio in the six months ended June 30, 2024.

In the six months ended June 30, 2024, Property segment underwriting income was reduced by total purchase accounting adjustments of $44.6 million, which added 2.4 percentage points to the Property segment combined ratio.

Below is a summary of the underwriting results and ratios for our Casualty and Specialty segment:

Casualty and Specialty Gross Premiums Written

In the six months ended June 30, 2024, our Casualty and Specialty segment gross premiums written increased by $1.0 billion, or 38.0%, to $3.8 billion, compared to $2.7 billion in the six months ended June 30, 2023. This increase is principally due to the renewal of business acquired in the Validus Acquisition, in conjunction with the retention and organic growth of legacy lines, and is primarily reflected in the other specialty, general casualty and credit classes of business, which grew by $640.2 million, $376.1 million and $127.8 million, respectively, compared to the six months ended June 30, 2023. This increase is partially offset by reductions to premium estimates on business underwritten in prior years in the six months ended June 30, 2024 compared to the six months ended June 30, 2023, which included positive premium adjustments. These changes in premium estimates occurred across various classes of business, but principally in the professional liability class of business which decreased by $106.0 million compared to the six months ended June 30, 2023, and is largely driven by adjustments received on reported premiums and revised ceding company estimates.

Casualty and Specialty Ceded Premiums Written

Ceded premiums written in our Casualty and Specialty segment increased by 11.7%, to $491.4 million, in the six months ended June 30, 2024, compared to $440.1 million in the six months ended June 30, 2023, primarily driven by the increase in gross premiums written subject to our retrocessional reinsurance programs, and partially offset by a decrease in amount of quota share retrocessional coverage purchased.

Casualty and Specialty Net Premiums Written

Net premiums written in our Casualty and Specialty segment decreased by $986.8 million, or 43.0%, consistent with the changes in gross premiums written and quota share retrocessional coverage purchased as discussed above.

Casualty and Specialty Underwriting Results

Our Casualty and Specialty segment generated underwriting income of $33.9 million in the six months ended June 30, 2024, compared to $140.9 million in the six months ended June 30, 2023. In the six months ended June 30, 2024, our Casualty and Specialty segment generated a net claims and claim expense ratio of 66.7%, an underwriting expense ratio of 32.2% and a combined ratio of 98.9%, compared to 62.5%, 30.5% and 93.0%, respectively, in the six months ended June 30, 2023.

The increase in the Casualty and Specialty segment combined ratio in the six months ended June 30, 2024 to 98.9% was principally driven by an increase of 4.2 percentage points in the net claims and claims expense ratio, mainly as a result of losses related to the Baltimore Bridge Collapse, which added approximately 2.0 percentage points to the current accident year net claims and claim expense ratio, as well as higher losses in the professional liability and credit classes of business during the second quarter.

During the six months ended June 30, 2024 our Casualty and Specialty segment also experienced net favorable development on prior accident years net claims and claim expenses of $26.3 million, or 0.9 percentage points, compared to $23.5 million, or 1.2 percentage points during the six months ended June 30, 2023. The net favorable development during the six months ended June 30, 2024 and the six months ended June 30, 2023 was primarily driven by reported losses generally coming in lower than expected on attritional net claims and claim expenses from our other specialty and credit classes of business.

See “Note 6. Reserve for Claims and Claim Expenses” in our “Notes to the Consolidated Financial Statements” for additional information related to the development of prior accident years net claims and claim expenses.

The underwriting expense ratio increased 1.7 percentage points driven by a 1.2 percentage point increase in the acquisition expense ratio from the impact of purchase accounting adjustments.

In the six months ended June 30, 2024, Casualty and Specialty segment underwriting income was reduced by total purchase accounting adjustments of $78.8 million, which added 2.6 percentage points to the Casualty and Specialty segment combined ratio.

In the six months ended June 30, 2024, total fee income earned through our third-party capital management activities increased by $66.2 million, to $167.6 million, compared to $101.5 million in the six months ended June 30, 2023, driven by both higher management fee income and higher performance fee income.

Management fee income increased $27.0 million compared to the six months ended June 30, 2023, driven by increased capital managed at DaVinci and Fontana, as well as the addition of fees earned by AlphaCat Managers.

Performance fee income increased $39.1 million compared to the six months ended June 30, 2023, driven by current underwriting year results and favorable development on prior year events, primarily in DaVinci and certain structured reinsurance products.

The fees earned through third-party capital management activities are principally recorded through redeemable noncontrolling interest, or as an increase to underwriting income through a decrease in operational expenses or acquisition expenses. Below is a summary of the impact of fee income on the applicable financial statement line items.

(1)Reflects total fee income earned through third-party capital management activities recorded through underwriting income (loss) as a decrease (increase) to operational expenses or acquisition expenses. The $27.7 million includes $28.0 million of management fee income, recorded as a reduction to operational expenses and $(0.3) million of performance fee income recorded as an increase to acquisition expenses (2023 - $21.3 million, $22.7 million and $(1.4) million, respectively).

In addition to the $27.7 million of fee income earned through our third-party capital management activities that was recorded through underwriting income (loss), as detailed above, we also earn additional fee income on certain other underwriting-related activities. These fees, in the aggregate, are recorded as a reduction to operational expenses or acquisition expenses, as applicable. The total fees recorded through underwriting income (loss) are detailed in the table below.

(1)The $65.0 million includes $58.4 million of management fee income, recorded as a reduction to operational expenses and $6.6 million of performance fee income recorded as a reduction to acquisition expenses (2023 - $72.2 million, $65.5 million and $6.7 million, respectively).

Net investment income was $801.6 million in the six months ended June 30, 2024, compared to $547.0 million in the six months ended June 30, 2023, an increase of $254.6 million, which was primarily driven by higher average invested assets, primarily resulting from the Validus Acquisition, and higher yielding assets in the fixed maturity and short term portfolios.

(1)Net realized and unrealized gains (losses) on investment-related derivatives includes fixed maturity investments related derivatives (interest rate futures and credit default swaps), equity investments related derivatives (equity futures) and commodity investments related derivatives (commodity futures and commodity options). See “Note 13. Derivative Instruments” for additional information.

Net realized and unrealized losses on investments were $341.2 million in the six months ended June 30, 2024, compared to gains of $56.7 million in the six months ended June 30, 2023, a decrease of $397.9 million. Principally impacting our net realized and unrealized losses on investments in the six months ended June 30, 2024 were:

•net realized and unrealized losses on our fixed maturity investments trading portfolio of $292.9 million compared to $6.7 million in the six months ended June 30, 2023, primarily as a result of generally higher increases in medium and long term interest rates in the six months ended June 30, 2024 compared to the six months ended June 30, 2023;

•net realized and unrealized losses on catastrophe bonds of $15.2 million, compared to net realized and unrealized gains of $62.3 million in the six months ended June 30, 2023. The net realized and unrealized gains (losses) are primarily reflected in the Medici portfolio, and are predominantly attributable to third-party investors and allocated through net income (loss) attributable to redeemable noncontrolling interest. Net realized and unrealized losses in the six months ended June 30, 2024 were the result of the widening of risk spreads in the catastrophe bond market, compared to the six months ended June 30, 2023, when there was a tightening of risk spreads; and

•net realized and unrealized gains on equity investments of $7.6 million compared to $32.3 million in the six months ended June 30, 2023, a decrease of $24.7 million. Both the current and comparative equity investment results were in line with public equity pricing movements. We reduced our exposure to public equities during the six months ended June 30, 2023 meaning net realized and unrealized gains on equity investments were less prominent in 2024.

Net Foreign Exchange Gains (Losses)

In the six months ended June 30, 2024, net foreign exchange losses were $44.5 million compared to $28.0 million in the six months ended June 30, 2023. The net foreign exchange losses for the six months ended June 30, 2024 and 2023 were driven by losses attributable to third-party investors in Medici which are allocated through net income (loss) attributable to redeemable noncontrolling interest, in addition to the impact of certain foreign exchange exposures related to our underwriting activities.

Refer to “Part II, Item 7A. Quantitative and Qualitative Disclosures About Market Risk” in our Form 10-K for the year ended December 31, 2023 for additional information related to our exposure to foreign currency risk and “Note 13. Derivative Instruments” in our “Notes to the Consolidated Financial Statements” for additional information related to foreign currency forward and option contracts we have entered into.

Equity in Earnings of Other Ventures

Earnings from our investments in other ventures was $26.7 million in the six months ended June 30, 2024, compared to $17.2 million in the six months ended June 30, 2023, an increase of $9.5 million. The increase was principally driven by increased profitability of certain of our insurance and insurance-related equity investments which reported higher net income in the six months ended June 30, 2024 compared to the six months ended June 30, 2023, as a result of negative fair value movements within their underlying investment portfolios in the prior period.

Corporate Expenses

Corporate expenses increased $38.2 million to $74.4 million, in the six months ended June 30, 2024, compared to $36.2 million in the six months ended June 30, 2023. The increase was primarily driven by $37.6 million of expenses associated with the Validus Acquisition, compared to $11.3 million in the comparative quarter.

Tax Benefit (Expense)

In the six months ended June 30, 2024, we recognized an income tax benefit of $5.5 million, compared to an income tax expense of $34.8 million in the six months ended June 30, 2023. The decrease in income tax expense was primarily driven by a $33.7 million deferred tax benefit resulting from the planned merger of RREAG and Validus Switzerland which was successfully completed in the second quarter of 2024.

Net Income (Loss) Attributable to Redeemable Noncontrolling Interests

Our net income attributable to redeemable noncontrolling interests was $469.6 million compared to $442.3 million in the six months ended June 30, 2023, an increase of $27.3 million. The increase was primarily driven by the following:

•DaVinci, which had net income in the six months ended June 30, 2024, primarily resulting from improved underwriting results and higher net investment income, partially offset by higher realized and unrealized losses on investments in the six months ended June 30, 2024, compared to the prior year; and

•Vermeer, which had higher net income in the six months ended June 30, 2024 compared to the six months ended June 30, 2023, primarily resulting from improved underwriting results in the six months ended June 30, 2024; partially offset by

•Medici, which had lower net income in the six months ended June 30, 2024 compared to the six months ended June 30, 2023, due to net realized and unrealized losses on its catastrophe bond portfolio in the current period, compared to net realized and unrealized gains in the six months ended June 30, 2023; and

•Fontana, which had a net loss in the six months ended June 30, 2024, compared to a net income in the six months ended June 30, 2023, primarily resulting from lower underwriting results, and an increase in net realized and unrealized losses on its investments, partially offset by higher net investment income in the six months ended June 30, 2024.
