Markel Corporation and Markel CATCo Announce Commencement of Schemes of Arrangement and Improved Terms of Buy-Out Transaction for Investors in Markel CATCo Reinsurance Fund Ltd. and CATCo Reinsurance Opportunities Fund Ltd.

RICHMOND,Va.,Oct. 26,2021 -- Markel Corporation (NYSE: MKL) and Markel CATCo Investment Management Ltd. (MCIM) today announced that,following the conclusion of the Early Consent Deadline of 22 October 2021 with respect to the Buy-Out Transaction announced on 27 September 2021,a substantial level of investor support for the transaction has been received,with investors representing over 90% of Markel CATCo Reinsurance Fund Ltd. (provisional liquidators appointed) (the Private Fund) and investors representing over 95% of CATCo Reinsurance Opportunities Fund Ltd. (provisional liquidators appointed) (the Public Fund,together with the Private Fund,the Funds) returning support undertakings or otherwise indicating their intention to support the Buy-Out Transaction.

Each of the boards of the Private Fund and Public Fund has resolved to proceed with the commencement of schemes of arrangement in Bermuda in order to implement the Buy-Out Transaction and will shortly issue a Practice Direction Letter to all investors.

As previously announced,the Buy-Out Transaction will be facilitated by affiliates of Markel Corporation providing funding of up to approximately $150 million to buy-out substantially all of the retrocessional segregated accounts of the Funds and tail risk cover that will allow for the return of approximately $100 million of trapped collateral to investors in the Private Fund's separately structured reinsurance offering,known as the Aquilo Fund segregated account.

Markel Corporation has agreed certain improvements to the terms of the Buy-Out Transaction which result in the buy-out of all segregated accounts of the Funds (including the Aquilo Fund),plus an additional cash distribution to investors by way of an increased consent fee and other cash consideration provided by Markel Corporations and its affiliates. The improved terms result in affiliates of Markel Corporation providing up to approximately $270 million for the full buy-out of the Funds and cash consideration of approximately $75 million.

Under the improved terms of the Buy-Out Transaction,investors in the Funds will still retain the right to receive any upside at the end of the applicable run-off period if currently held reserves exceed the amounts necessary to pay ultimate claims. The affiliates of Markel Corporation financing the Buy-Out Transaction expect to receive a return of all their funding in relation to the full buy-out of the Funds by the end of the run-off periods.

To allow for investors who have not yet returned support undertakings to consider these improved terms,the deadline for investors to enter into an undertaking to support the Buy-Out Transaction has now been extended to 11.59 p.m. ADT on 9 November 2021 (the Extended Early Consent Deadline).

Certain of the statements in this announcement or (and any related oral statements) may be considered forward-looking statements. This announcement (including information incorporated by reference in this announcement),oral statements made regarding the Buy-Out Transaction and other information published by Markel Corporation,MCIM and the Funds contain statements which are,or may be deemed to be,"forward-looking statements" as defined in the Private Securities Litigation Reform Act of 1995.

Forward-looking statements are prospective in nature and are not based on historical facts,but rather on current expectations and projections of the management of Markel Corporation,MCIM and the Funds about future events,and are therefore subject to risks and uncertainties which could cause actual results to differ materially from the future results expressed or implied by the forward-looking statements. The forward-looking statements contained in this announcement include statements relating to the expected effects of the Buy-Out Transaction,the expected timing and scope of the Buy-Out Transaction and other statements other than historical facts. Often,but not always,forward-looking statements can be identified by the use of forward-looking words such as "plans","expects" or "does not expect","is expected","is subject to","budget","projects","strategy","scheduled","estimates","forecasts","intends","anticipates" or "does not anticipate",or "believes",or variations of such words and phrases or statements that certain actions,events or results "may","could","should","would","might" or "will" be taken,occur or be achieved. Although Markel Corporation,MCIM and the Funds believe that the expectations reflected in such forward-looking statements are reasonable,they can give no assurance that such expectations will prove to be correct. By their nature,forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that will occur in the future.

There are a number of factors that could cause actual results and developments to differ materially from those expressed or implied by such forward-looking statements. These factors include,but are not limited to: the ability to complete the Buy-Out Transaction; the ability to obtain requisite regulatory and other required approvals and the satisfaction of other conditions on the proposed terms and schedule; as future market conditions,changes in general economic and business conditions,the behavior of other market participants,the anticipated benefits from the proposed transaction not being realized as a result of changes in general economic and market conditions in the countries in which the Funds operate,weak,volatile or illiquid capital and/or credit markets,changes in tax rates,interest rate and currency value fluctuations,the degree of competition in the geographic and business areas in which the Funds operate and changes in laws or in supervisory expectations or requirements.

Other unknown or unpredictable factors could cause actual results to differ materially from those in the forward-looking statements. Such forward-looking statements should therefore be construed in the light of such factors. Neither Markel Corporation,MCIM nor the Funds,nor any of their respective associates or directors,officers or advisers,provides any representation,assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this announcement will actually occur.
