22 March 2024

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 9 May 2024 at 12.30 pm (local time). For convenience, Shareholders may view a webcast of the AGM and ask questions via a video link at the Group's London office, 22 Bishopsgate, London EC2N 4BQ on 9 May 2024 at 4.30 pm (BST). If you wish to watch the webcast in London, please email investor.relations@hiscox.com on or before 2 May 2024 to enable us to arrange access to our 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 5 to 6 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 investor.relations@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 18 inclusive will be proposed as ordinary resolutions and Resolutions 19 to 21 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 2023.

Resolution 2

Approval of the annual report on remuneration 2023

The Directors seek approval of the annual report on remuneration for the year ended 31 December 2023 which can be found on pages 112 to 122 of the 2023 Annual Report and Accounts. This vote is advisory and non-binding.

Resolution 3

Approval of the final dividend for the year ended 31 December 2023

The Directors seek approval for a final dividend of 25.0 cents per share as approved by the Board to be paid on 12 June 2024 to Shareholders on the register on 3 May 2024. 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 20 May 2024. Shareholder and Depositary Interest Holders who have already elected for the scrip dividend alternate do not need to take further action.

Resolutions 4 to 15

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 2018 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 30 May 2023, Jonathan Bloomer joined the Board as Chair designate on 1 June 2023, succeeding Robert Childs as Chair with effect from 1 July 2023. Additionally, as announced on 12 May 2023, Beth Boucher joined the Board as an independent Non Executive Director. As such, both Jonathan and Beth are standing for election for the first time.

Each of Anne MacDonald and Lynn Pike, two of our Non Executive Directors, were appointed in May 2015 and will therefore have served nine years on the Board this spring. The Board continues to value both Anne and Lynn's skills and experience, and considers that each of them continues to demonstrate independence, constructive challenge and engagement in Board and Committee meetings. The Board is therefore satisfied that Anne and Lynn continue to show the independence of character and judgement necessary to fulfil their roles effectively. The Nominations and Governance Committee continues to consider Board succession planning and refreshment on a regular basis.

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 7 to 8 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

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

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 16 and 17

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 2024 financial year.

Resolution 18

To authorise the allotment of relevant securities

Authority was granted to the Directors at the AGM held on 11 May 2023 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 £7,508,599 and an additional nominal amount of £7,508,599 in connection with a Rights Issue for a period expiring at the conclusion of the next AGM. As at 15 March 2024, the Company's issued ordinary share capital amounted to £23,063,050 comprising 354,816,160 Ordinary Shares, of which the Company held 7,523,190 Ordinary Shares in treasury, representing 2.12% 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).

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 2025 AGM of the Company or, if earlier, on 1 July 2025. 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 (£7,524,681), or up to two-thirds (£ 15,049,362) 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 15 March 2024 (being the latest practicable date prior to publication of this circular).

Resolutions 19 and 20

To dis-apply pre-emption rights

Resolution 19 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 2025, 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 19 and 20 are within institutional shareholder guidance and in particular the Pre-Emption Group's Statement of Principles (the 'Pre-Emption Principles'). The Pre-Emption Principles were revised in November 2022 to 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 19 therefore authorises the Directors, pursuant to the authority given by Resolution 18 (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 15 March 2024 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 15 March 2024 otherwise than in connection with a pre-emptive offer to existing Shareholders.

In addition, Resolution 20 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 15 March 2024 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 18, 19 or 20, 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 2023 were not used.

Resolution 21

To authorise the Company to purchase its own Ordinary Shares

Resolution 21 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 34,729,297 Ordinary Shares representing approximately 10% of the nominal amount of the issued ordinary capital of the Company (excluding shares held in treasury) on 15 March 2024. 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 15 March 2024 (being the latest practicable date prior to the publication of this circular) is 8,771,124 representing 2.53% 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 Listing Rule 13.7.1(1) (f), the authority given by this resolution and that granted at the previous AGM were aggregated and fully utilised, these shares would represent 19.55% 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 2025 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 commenced a buyback of its issued ordinary shares on 5th March 2024 for a maximum consideration of \$150 million. 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.

Notes

• 1. Every Shareholder has the right to appoint some other person(s), who need not be a Shareholder, as his/her proxy to attend, speak and vote on their behalf at the AGM. A Shareholder may appoint more than one proxy in relation to the AGM provided that each proxy is appointed to exercise the rights attached to a different share or shares held by that Shareholder. In order to be valid, any appointment of proxy (and the power of attorney or other authority, if any, under which it is signed or a notarially certified or office copy of such power or authority) must be undertaken in accordance with these notes and the notes set out on the accompanying Form of Proxy and returned in hard copy form by post to the Company's registrars' UK agent, Equiniti Limited, Aspect House, Spencer Road, Lancing, West Sussex BN99 6DA, United Kingdom, not later than 48 hours before the time for holding the AGM (or in the event that the AGM is adjourned, 48 hours before the time of any adjourned meeting).
• 1. Return of the Form of Proxy will not preclude a Shareholder from attending the Meeting and voting in person.
• 1. In accordance with Bye-law 41 of the Company's Bye-laws, only those Shareholders entered on the Register of Members of the Company as at 6.30 pm (BST) on 7 May 2024 (or in the event that the Meeting is adjourned, 2.30 pm (local time)(6.30 pm (BST)) on the date two days before the date of any adjourned Meeting) as the holder of Ordinary Shares, their validly appointed proxies and validly appointed Depositary Proxies shall be entitled to attend or vote at the Meeting in respect of the number of Ordinary Shares registered in the Shareholder's name (or in the name of the Depositary as the case may be) at that time. Changes to entries on the Register of Shareholders after 6.30 pm (BST) on 7 May 2024 (or in the event that the Meeting is adjourned, 6.30 pm (BST) on the date two days before the date of any adjourned meeting) shall be disregarded in determining the rights of any person to attend or vote at the meeting.
• 1. A Depositary Interest Holder who is a CREST member and who wishes to appoint, or to give instruction to, the Depositary through the CREST electronic proxy appointment service may do so by using the procedures described in the CREST Manual. CREST Personal Members or other CREST sponsored members, and those CREST members who have appointed a service provider(s), should refer to their CREST sponsor or voting service provider(s), who will be able to take the appropriate action on their behalf. 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. The message, regardless of whether it constitutes the appointment of a proxy or is an amendment to the instruction given to a previously appointed proxy must, in order to be valid, be transmitted so as to be received by the issuer's agent (ID 7RA01) by 12.30 pm (local

Hiscox Ltd Notice of 2024 Annual General Meeting (continued)

time) (4.30 pm (BST)) on 6 May 2024 (or, if the meeting is adjourned, 72 hours before the time fixed for the adjourned meeting). For this purpose, the time of receipt will be taken to be the time (as determined by the time stamp applied to the message by the CREST Application Host) from which the issuer's agent is able to retrieve the message by enquiry to CREST in the manner prescribed by CREST. 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.
