17 March 2025

Dear Shareholder

I am writing on behalf of the Board to provide an explanation of the business to be considered at the forthcoming Annual General Meeting (AGM) of Hiscox Ltd (the 'Company'). The formal notice convening this meeting is set out at the end of this letter.

Location, attendance and voting

The AGM will be held at Chesney House, 96 Pitts Bay Road, Pembroke HM 08, Bermuda on 15 May 2025 at 12.30 pm (local time). For convenience, Shareholders may view a webcast of the AGM and ask questions via a video link at Peel Hunt LLP's office, 100 Liverpool Street, London EC2M 2AT on 15 May 2025 at 4.30 pm (BST). If you wish to watch the webcast in London, please email companysecretary@hiscox.com on or before 8 May 2025 to enable us to arrange access to Peel Hunt's offices. Note that the webcast is for informational purposes and Shareholders will not be able to vote at the AGM via the video link so should cast their votes in advance – see pages 6 to 7 for further details.

To the extent that we need to make changes to the arrangements described above, we will announce by regulatory informational announcement any changes as early as is possible before the date of the meeting. Shareholders should monitor the Company's website for any updates in relation to the AGM.

The Board recognises the opportunity that the AGM provides for shareholders to ask questions that they have relating to the Company. Therefore, the Board encourages shareholders to send their questions by email to companysecretary@hiscox.com in advance of the AGM and we will endeavour to respond to your questions before the proxy voting deadline. Responses to questions received will be posted on the Company's website.

Business of the AGM

The following business will be proposed at the AGM. The Board believes that all of the resolutions set out in this Notice are in the best interests of both Hiscox and its shareholders. Resolutions 1 to 21 inclusive will be proposed as ordinary resolutions and Resolutions 22 to 24 inclusive as special resolutions.

Resolution 1

Annual Report and Accounts

The Directors of the Company (the 'Directors') present the Annual Report and Accounts for the year ended 31 December 2024.

Resolution 2

Approval of the Directors remuneration report 2024

The Directors seek approval of the Directors remuneration report for the year ended 31 December 2024 which can be found on pages 126 to 139 of the 2024 Annual Report and Accounts. This vote is advisory and non-binding.

Resolution 3

To increase the maximum fees payable to Directors

The Company's Bye-laws (as adopted in 2015) currently provide that Directors' fees shall not exceed £1,250,000 per annum in aggregate. The effect of this provision is to limit the fees (other than any remuneration or fees for special or extra services) that may be paid to the Non Executive Directors. The fee cap has been set at £1,250,000 since 2014. The salary and remuneration of the Executive Directors is dealt with separately under the Bye-laws.

Although there are no current plans to make any material changes to the fees paid to Non Executive Directors, an external benchmarking exercise will take place in 2025 (given the Company has not increased Non Executive Director fees since 2020, save for the Chair fee which was increased in June 2023 when Jonathan Bloomer was appointed) to ensure that the fees remain suitable for the role and allow the Company to attract the appropriate calibre of Director. The 2025 Board succession plans as described in the Annual Report and Accounts mean that there may be a brief overlap for incoming and outgoing Directors to ensure continuity. In light of the fact that the fee cap was last reviewed more than ten years ago, the proposed benchmarking exercise and the Board succession plans, the Board considers it desirable to increase the fee limit contained in the Bye-laws to £1,750,000 per annum in aggregate. In accordance with the terms of Bye-law 67, Resolution 3 is proposed as an ordinary resolution.

Resolution 4

Approval of the final dividend for the year ended 31 December 2024

The Directors seek approval for a final dividend of 29.9 cents per share as approved by the Board to be paid on 9 June 2025 to Shareholders on the register on 25 April 2025. The dividend is to be paid in cash in respect of each Ordinary Share and Depositary Interest, other than those Ordinary Shares and Depositary Interests in respect of which a valid election has been made in relation to the Scrip Dividend alternative approved at the AGM held on 12 May 2022. Further details regarding the dividend alternative, including the procedure to be followed in order to make an election, are set out in the circular which was sent to shareholders in April 2022, a copy of which is available on the Company's website at www.hiscoxgroup.com. The deadline for making an election for the Scrip Dividend alternative so that it will apply is 19 May 2025. Shareholder and Depositary Interest Holders who have already elected for the scrip dividend alternate do not need to take further action.

Resolutions 5 and 6

Approval of the 2025 Scrip Dividend Scheme and capitalising related sums

The current authority from Shareholders to offer a Scrip Dividend alternative expires at the forthcoming AGM. The Directors are proposing that the Company continues to offer an optional Scrip Dividend alternative. This allows Shareholders and Depositary Interest Holders to elect to receive new Ordinary Shares (credited as fully paid) or new Depositary Interests in the capital of the Company instead of future cash dividends. This has potential benefits to Shareholders and Depositary Interest Holders who opt into the Scrip Dividend (to increase their holding without incurring dealing costs or stamp duty) and provides the Directors with flexibility in the management of the Company's capital resources.

Subject to the approval of Shareholders, and in line with institutional investor guidelines, the Scrip Dividend alternative will run for three years ending at the conclusion of the AGM in 2028 and during that period will be offered at the discretion of the Directors. Shareholders and Depositary Interest Holders who elect to take new Ordinary Shares or new Depositary Interests in the Company under the Scrip Dividend alternative will increase their holding or interest in the Company in a simple manner without incurring any dealing costs. The number of new Ordinary Shares and new Depositary Interests that Shareholders and Depositary Interest Holders will receive for each dividend will depend on the amount of the cash dividend, the number of Ordinary Shares or Depositary Interests (as the case may be) held, the Scrip reference share price to be used in calculating Shareholders' and Depositary Interest Holders' entitlements and, for Shareholders only, any residual cash balance brought forward from the last Scrip Dividend. A separate circular, including the full terms and conditions of the Company's new Scrip Dividend scheme, is enclosed with this Notice.

In accordance with the Company's Bye-laws, approval is also sought to capitalise sums standing to the credit of the reserves of the Company. This would enable the Directors to apply such sums in paying up in full the nominal amounts of new Ordinary Shares and new Depositary Interests allotted to Shareholders and Depositary Interest Holders pursuant to elections under the Scrip Dividend alternative.

Resolutions 7 to 18

Appointment and re-appointment of Directors

The Bye-laws require that a Director shall retire from office if he/she has been appointed by the Board since the previous AGM or it is the third AGM following that at which he/she was last re-appointed. However, in accordance with the 2024 Corporate Governance Code (Governance Code) all the Directors will, being eligible, offer themselves for appointment or re-appointment at the AGM, as applicable.

As announced on 2 September 2024, Jane Guyett has joined the Board as an independent Non Executive Director and Chair of the Remuneration Committee. Additionally, as announced on 27 January 2025, Lynne Biggar and June Yee Felix have also joined the Board as independent Non Executive Directors and, as a result, each of Lynn Pike and Anne MacDonald will stand down from the Board at the end of the AGM. The Board would like to welcome Jane, Lynne and June and sincerely thank Lynn and Anne for their valuable contributions to the success of the Group and the Board during their respective tenures.

As such, each of Jane, Lynne and June are standing for election for the first time and all of the remaining Directors (excluding Lynn and Anne) are standing for re-election at the AGM.

Our Interim Chair, Colin Keogh, was appointed to the Board in November 2015 and has therefore served more than nine years on the Board. The Board continues to value Colin's

skills and experience, and in particular his leadership during this period of transition following the sudden death of our former Chair, Jonathan Bloomer. The Board considers that Colin continues to demonstrate independence, constructive challenge and engagement in both Board and Committee meetings and is therefore satisfied that he continues to show the independence of character and judgement necessary to fulfil his role effectively. It is intended that Colin will remain in post until a permanent Chair has been appointed (the process for which is well advanced) and following an appropriate period of handover.

Biographical details of each Director and the reasons why their contribution is, and continues to be, important to the Company's long-term sustainable success can be found on pages 8 to 10 of this Notice. The Chair and the Board have considered the individual skills, experience and attributes of each Director. The Board considers that the composition of the Board is well balanced and therefore recommends the appointment or re-appointment of each Director at the AGM. Following a formal performance evaluation, the Chair has confirmed in respect of all Directors offering themselves for appointment or re-appointment at the AGM that their performance continues to be effective and to demonstrate commitment and independence to the role. The Nominations and Governance Committee also assessed the Board performance and were satisfied that all Directors had sufficient time to dedicate to their role. The Senior Independent Director also assessed the Chair's performance in fulfilling his role.

Resolution 19 and 20

Approval of the Auditors' re-appointment and setting of their remuneration

Having assessed their independence, performance and effectiveness and evaluating their work throughout the year, the Board proposes that PricewaterhouseCoopers LLP be re-appointed as auditors of the Company for the 2024 financial year and that the Audit Committee be authorised to negotiate and agree the audit fee for the 2025 financial year.

Resolution 21

To authorise the allotment of relevant securities

Authority was granted to the Directors at the AGM held on 9 May 2024 in accordance with Bye-law 5(b) of the Company's Bye-laws to allot relevant securities without the prior consent of Shareholders up to a maximum nominal amount of £7,524,681 and an additional nominal amount of £7,524,681 in connection with a Rights Issue for a period expiring at the conclusion of the next AGM. As at 6 March 2025, the Company's issued ordinary share capital amounted to £22,586,233 comprising 347,480,514 Ordinary Shares, of which the Company held 7,523,190 Ordinary Shares in treasury, representing 2.17% of the Company's issued ordinary share capital.

The Directors consider it appropriate to renew this authority at the forthcoming AGM to maintain the flexibility this authority provides. The proposed new authority will allow the Directors to allot relevant securities equal to an amount of up to one third of the Company's existing ordinary issued share capital plus, in the case of a fully pre-emptive Rights Issue only, a further amount of up to an additional one third of the Company's existing issued ordinary share capital (in each case excluding any shares held in treasury).

To holders of Ordinary Shares ('Shareholders') and for information only to holders of depositary interests issued by Equiniti Limited in respect of Ordinary Shares ('Depositary Interests Holders') continued

This authority is within the guidelines of the Share Capital Management Guidelines issued by the Investment Association in February 2023.

The proposed new authority will expire at the conclusion of the 2026 AGM of the Company or, if earlier, on 1 July 2026. It is the current intention to renew this authority annually to maintain the flexibility this authority provides. The Directors have no present intention to allot shares other than in connection with employee share schemes and the scrip dividend alternative. If the Directors exercise the authority, they intend to follow best practice as regards its use, as recommended by the Investment Association.

The nominal amount of securities to which the new authority will relate represents approximately one-third (£7,365,742), or up to two-thirds (£14,731,484) in the case of a fully pre-emptive Rights Issue only, of the Company's issued ordinary share capital (excluding shares held in treasury) as at 6 March 2025 (being the latest practicable date prior to publication of this circular).

Resolutions 22 and 23

To dis-apply pre-emption rights

Resolution 22 is proposed as a special resolution in accordance with Bye-law 7(a) of the Company's Bye-laws to authorise the Directors to allot equity securities for cash or to sell treasury shares without first being required to offer such shares to existing Shareholders. This authority will expire at the conclusion of the next AGM or, if earlier, on 1 July 2026, although it is the Directors' current intention to seek renewal of this authority annually to maintain the flexibility this authority provides.

The authorities set out in Resolutions 22 and 23 are within institutional shareholder guidance and in particular the Pre-Emption Group's Statement of Principles (the 'Pre-Emption Principles'). The Pre-Emption Principles issued in November 2022 allow the authority for an issue of shares for cash otherwise than in connection with a pre-emptive offer to include: (1) an authority up to 10% of a company's issued share capital for use on an unrestricted basis; and (2) an additional authority up to a further 10% of a company's issued share capital for use in connection with an acquisition or specified capital investment announced contemporaneously with the issue, or that has taken place in the twelve month period preceding the announcement of the issue. In both cases, an additional authority of up to 2% may be sought for the purposes of making a follow-on offer as described in the Pre-Emption Principles.

Having considered the Pre-Emption Principles, the Directors consider it appropriate to seek a disapplication authority over 10% of the Company's issued share capital for use on an unrestricted basis as well as a further 10% for use in connection with an acquisition or specified capital investment.

Resolution 22 therefore authorises the Directors, pursuant to the authority given by Resolution 21 (the authority to allot resolution) to allot:

a. equity securities for cash and to sell treasury shares up to a nominal amount representing two-thirds of the Company's issued share capital as at 6 March 2025 on an offer to existing Shareholders in connection with a

Rights Issue, subject to any exclusions or such other arrangements as the Director may consider appropriate to resolve legal or practical problems which, for example, might arise with overseas Shareholders; and

b. equity securities for cash and to sell treasury shares up to a nominal amount representing not more than 10% of the nominal value of the issued share capital of the Company as at 6 March 2025 otherwise than in connection with a pre-emptive offer to existing Shareholders.

In addition, Resolution 23 authorises the Directors to allot new shares for cash and to sell treasury shares up to a nominal amount representing not more than 10% of the nominal value of the issued share capital of the Company as at 6 March 2025 without those shares first being offered to existing Shareholders in proportion to their existing holdings, for the purposes of financing or refinancing a transaction as contemplated by the Pre-Emption Principles described above.

The Directors confirm that they intend to follow the shareholder protections contained in Part 2B of the Pre-Emption Principles in connection with any non-pre-emptive offering.

The Directors have no present intention of using the authorities set out in Resolutions 21, 22 or 23, however, they consider that it is in the best interests of the Company and its Shareholders generally that the Company have the authorities available so that the Board has the flexibility to issue securities at short notice, and without the need for a general meeting, should the Board determine that it is appropriate to do so, for example to finance business opportunities quickly and efficiently when they arise. The equivalent authorities granted in 2024 were not used.

Resolution 24

To authorise the Company to purchase its own Ordinary Shares

Resolution 24 is proposed as a special resolution in accordance with Bye-law 9(a) of the Company's Bye-laws to give the Company a general authority to make market purchases of its own shares. The maximum number of shares that the Company may purchase under this authority will be 33,995,732 Ordinary Shares representing approximately 10% of the nominal amount of the issued ordinary capital of the Company (excluding shares held in treasury) on 6 March 2025. The resolution also sets out the maximum and minimum price which the Company may pay for those shares. Any shares purchased under this authority may be cancelled or held in treasury. It is the Directors' current intention to cancel any shares purchased.

The total number of shares over which an option under an employee share scheme exists as at 6 March 2025 (being the latest practicable date prior to the publication of this circular) is 8,671,491 representing 2.55% of the Company's issued ordinary share capital (excluding shares held in treasury). Although the authority being sought at the AGM is in place of that granted at the previous AGM if, for the purposes of UK Listing Rule 10.5.1, the authority given by this resolution and that granted at the previous AGM were aggregated and fully utilised, these shares would represent 3.20% of the Company's issued

ordinary share capital (excluding shares held in treasury) at that date.

This authority will expire at the conclusion of the next AGM of the Company or, if earlier, on 1 July 2026 although it is the Directors' current intention to seek renewal of this authority annually. The power given by the resolution will only be exercised if the Directors are satisfied that any purchase will increase the earnings per share of the ordinary share capital in issue after the purchase and, accordingly, that the purchase is in the interests of Shareholders. The Directors will also give careful consideration to gearing levels of the Company and its general financial position. The Company announced a buyback of its issued ordinary shares for a maximum consideration of \$175 million on 27 February 2025 and commenced the buyback of an initial tranche of up to \$87.5 million on the same day. The purpose is to return additional capital to shareholders. Hiscox will cancel all purchased shares.

Recommendation

The Board believes that the proposed resolutions as set out in the Notice of AGM are in the best interests of the Company and the Shareholders as a whole and the Board recommends that the Shareholders vote in favour of the resolutions. Each Director who holds shares in the Company intends to vote in favour of the resolutions.

In order for a proxy appointment or instruction made using the CREST service to be valid, the appropriate CREST message (a CREST Proxy Instruction) must be properly authenticated in accordance with Euroclear UK & Ireland Limited's specifications, and must contain the information required for such instruction, as described in the CREST Manual.

After this time any change of instructions to proxies appointed through CREST should be communicated to the appointee through other means. CREST members and, where applicable, their CREST sponsors, or voting service providers should note that Euroclear UK & Ireland Limited does not make available special procedures in CREST for any particular message. Normal system timings and limitations will, therefore, apply in relation to the input of CREST Proxy Instructions. It is the responsibility of the CREST member concerned to take (or, if the CREST member is a CREST personal member, or sponsored member, or has appointed a voting service provider, to procure that his/her CREST sponsor or voting service provider(s) take(s)) such action as shall be necessary to ensure that a message is transmitted by means of the CREST system by any particular time. In this connection, CREST members and, where applicable, their CREST sponsors or voting system providers are referred, in particular,

to those sections of the CREST Manual concerning practical limitations of the CREST system and timings. The Company may treat as invalid a CREST Proxy Instruction in the circumstances set out in Regulation 35(5)(a) of the Uncertificated Securities Regulations 2001.
