CORRECTION: Endurance Reports Excellent First Quarter 2016 Underwriting Profitability With a Combined Ratio of 77.9%

PEMBROKE, Bermuda - May 2, 2016 - Endurance Specialty Holdings Ltd. (NYSE:ENH) today reported net income available to common shareholders of $106.4 million and $1.58 per diluted common share for the first quarter of 2016 versus net income of $100.3 million and $2.23 per diluted common share for the first quarter of 2015. Book value per diluted common share was $67.03 at March 31, 2016, up 2.4% from December 31, 2015.

John R. Charman, Chairman and Chief Executive Officer, commented, "I am delighted with the excellent underwriting profitability that my colleagues in Endurance have generated in the first quarter. Our combined ratio of 77.9% reflects both the continuing high quality of our global underwriting activity as well as the very successful integration of our acquisition of Montpelier. In addition to retaining nearly all the Montpelier business we had anticipated, our speedy and smooth operational integration has generated the planned expense synergies that are already clearly visible in our financial results. While global competition across both Insurance and Reinsurance has continued in line with our expectations, our unique execution, based on targeted, profitable growth, continues to be highly successful. This integrated, corporate underwriting strategy is driven daily by our market leading underwriters implementing our very disciplined risk selection procedures. Endurance is now able to fully leverage the significant global investments that we have made over the last three years in people, products, geographies, systems and analytics to positively differentiate our underwriting performance and profitability regardless of how challenging market conditions may be."

• Net investment income of $11.2 million, a decrease of $30.7 million from the same period in 2015.
• Operating income of $84.4 million and $1.26 per diluted common share, a decrease of 7.4% and 37.9%, respectively, compared to the same period in 2015.

Insurance Segment

Operating highlights for Endurance's Insurance segment for the quarter ended March 31, 2016:

• Gross premiums written of $835.1 million, an increase of $98.9 million or 13.4% from the first quarter of 2015.
  • Non-agriculture lines of business, which include casualty and other specialty, professional lines and property, marine/energy and aviation lines of business grew 54.5% from a year ago driven by the continued underwriting and geographic expansion implemented over the last three years as well as the renewal and expansion of business written within the Company's Lloyd's syndicate acquired from Montpelier in 2015.
  • The agriculture insurance line of business declined 4.0% primarily as a result of lower commodity prices compared to a year ago.
• Net premiums written of $370.9 million, an increase of $66.9 million or 22.0% from the first quarter of 2015.
  • Non-agriculture lines of business increased 59.8% due to strong growth in gross premiums written combined with a modestly lower percentage of premiums ceded to third party reinsurers.
  • The agriculture line of business increased 3.0% due to the timing of third party reinsurance contract placements year over year.
• Combined ratio of 89.5% compared to 87.8% for the same period in 2015. The current period's combined ratio included favorable prior year loss reserve development of 10.6 percentage points.
  • The current accident year net loss ratio improved 1.2 percentage points as lower losses within the agriculture and professional lines of business were partially offset by higher net loss ratios within the casualty and other specialty, and property, marine/energy and aviation lines of business.
  • A decrease in the general and administrative expense ratio of 3.8 percentage points reflecting earned premium growth that outpaced the increase of our expense base as a result of improved scale in our expanding insurance business.
  • The acquisition expense ratio increased 2.1 percentage points in the current quarter as non-agriculture business lines with higher acquisition costs accounted for a greater percentage of earned premiums than a year ago.

Reinsurance Segment

Operating highlights for Endurance's Reinsurance segment for the quarter ended March 31, 2016:

• Gross premiums written of $776.6 million, an increase of $211.3 million or 37.4% from the first quarter of 2015.
  • The catastrophe and property lines of business increased $107.2 million predominantly due to the targeted renewal of acquired Montpelier business.
  • The specialty line of business increased $58.8 million largely due to growth in marine, agriculture and trade credit and surety, as global underwriting teams added over the past three years continue to identify new and profitable opportunities.
  • The casualty line of business increased $40.6 million, predominantly driven by new business within our international and U.S. offices.
• Net premiums written of $567.9 million, an increase of $107.0 million or 23.2% from the first quarter of 2015 driven by increased gross written premiums, partially offset by greater third party retrocessional protection purchased for the specialty line of business.
• Combined ratio of 66.8% compared to 74.7% for the same period in 2015. The current period's combined ratio included 11.4 percentage points of favorable prior year loss reserve development and net catastrophe losses from 2016 events of $4.5 million or 1.4 percentage points.
  • The favorable decline in the current quarter accident year net loss ratio of 6.6 percentage points was due to improvements within the catastrophe, specialty and casualty lines of business, partially offset by a modest increase within professional lines.
  • The 4.1 percentage point improvement in the current quarter's acquisition expense ratio was largely attributed to the earning of premiums acquired from Montpelier that do not have related acquisition costs as these were written off at the date of the acquisition.
  • The general and administrative expense ratio decreased 0.2 percentage points in the first quarter of 2016 primarily as a result of increased earned premiums, partially offset by expenses related to newly hired underwriting teams.

ENDURANCE SPECIALTY HOLDINGS LTD.
RECONCILIATIONS
(in thousands of United States dollars, except share, per share amounts and ratios)

The following is a reconciliation of Endurance's net income, net income per basic or diluted common share, net income allocated to common shareholders under the two-class method and annualized return on average common equity to operating income, operating income per basic or diluted common share, operating income allocated to common shareholders under the two-class method and annualized operating return on average common equity (all non-GAAP measures) for the quarter ended March 31, 2016 and 2015:

[a] Average common equity is calculated as the quarterly weighted average of the beginning and ending common equity balances for the stated period, which excludes the $460.0 million (March 31, 2015 and December 31, 2014 - $430.0 million) liquidation value of the preferred shares.
[b] Represents diluted income per share calculated under the two-class method which was the lower of the treasury stock method and the two-class method.

Operating income and operating income per basic or diluted common share are internal performance measures used by Endurance in the management of its operations. Operating income allocated to common shareholders (excludes unvested restricted shares outstanding which are considered participating) per diluted common share represents operating income divided by weighted average dilutive common shares, which has been calculated in accordance with the two-class method under U.S. GAAP. Operating income represents after-tax operational results excluding, as applicable, after-tax net realized and unrealized capital gains or losses and after-tax net foreign exchange gains or losses because the amount of these gains or losses is heavily influenced by, and fluctuates in part, according to the availability of market opportunities. Endurance believes these amounts are largely independent of its business and underwriting process and including them distorts the analysis of trends in its operations. In addition to presenting net income and net income per dilutive common share determined in accordance with the two-class method under GAAP, Endurance believes that showing operating income and operating income per dilutive common share enables investors, analysts, rating agencies and other users of its financial information to more easily analyze Endurance's results of operations in a manner similar to that used by management to analyze the Company's underlying business performance. Operating income and operating income per dilutive common share should not be viewed as substitutes for GAAP net income and net income per dilutive common share, respectively.

Endurance presents return on equity as a measure that is commonly recognized as a standard of performance by investors, analysts, rating agencies and other users of its financial information.
