Re: General Meeting of Renalytix plc

Dear Shareholders,

On behalf of our Board of Directors, I am pleased to invite you to a general meeting (the “General Meeting”) of Renalytix plc (the “Company”). The General Meeting will be held at 12 noon (GMT) on October 31, 2024 at 6 Stratton Street, London W1J 8LD.

This letter, the notice of General Meeting set out in this document (the “Notice of General Meeting”), and associated materials for the General Meeting are being sent, or otherwise made available, to you because, as of October 7, 2024, you are registered as a holder of ordinary shares in the register of members of the Company. On or about October 15, 2024, this letter, the Notice of General Meeting and associated materials will also be made available to holders of American Depositary Shares (“ADSs”) and contains information relevant to holders of ADSs. For the avoidance of doubt, references to “ADSs” includes restricted ADSs.

The Notice of General Meeting is set out in this document, and it contains the resolutions that make up the proposals to be proposed at the General Meeting (the “Resolutions”).

Details regarding the business to be conducted at the General Meeting, and admission to the General Meeting, are described in the accompanying Notice of General Meeting, proxy statement and the enclosed ADS Proxy Card (if applicable). For the purposes of the General Meeting, a quorum will be formed by two qualifying persons present at the meeting and between them holding at least 33 1/3 percent in number of the issued shares. A “qualifying person” is an individual who is a member, a person authorized to act as the representative of a member (being a corporation) in relation to the meeting or a person appointed as proxy of a member in relation to the meeting.

ACTION TO BE TAKEN BY HOLDERS OF ORDINARY SHARES IN THE COMPANY IN RESPECT OF THE GENERAL MEETING

If you are a holder of ADSs, please refer to the section below — “Holders of American Depositary Shares”.

You will not receive a hard copy form of proxy with this document.

Proxies submitted via CREST (under ID RA10) must be sent as soon as possible and in any event delivered by no later than 12 noon (GMT) on October 29, 2024, in order to be valid. The completion and return of a form of proxy, submitting a

QUESTIONS AND ANSWERS ABOUT VOTING

1) Why am I receiving these materials?

Ordinary shareholders

We have sent, or otherwise made available to, you this proxy statement and related materials because you are an ordinary shareholder of record and our Board of Directors is soliciting your proxy to vote at the Meeting, including at any adjournments or postponements of the Meeting. You are invited to attend the General Meeting in person to vote on the resolutions described herein. However, you do not need to attend the Meeting to vote your shares. Instead, you can submit your vote electronically by accessing the Link Investor Centre web browser at https://investorcentre.linkgroup.co.uk/Login/Login/. If you are an institutional investor, you may vote via the Proxymity platform. You may request a hard copy form of proxy directly from Link Group, shareholderenquiries@linkgroup.co.uk or on +44(0)371 664 0391. Full details are set out in the notes to the Notice of General Meeting. Proxies submitted electronically or hard copy forms of proxy must be submitted by no later than 12 noon (GMT) on October 29, 2024.

CREST members may appoint a proxy by using the CREST electronic proxy appointment service. CREST members who wish to appoint a proxy or give an instruction through the CREST electronic proxy appointment service may do so by using the procedures described in the CREST manual.

You are encouraged to appoint the Chairman of the Meeting as your proxy.

Materials for ordinary shareholders will be mailed, or otherwise made available, on or about October 15, 2024 to all ordinary shareholders as of October 7, 2024.

ADS holders

Materials for ADS holders of record, including the Notice of General Meeting, this proxy statement and an ADS proxy card (the “ADS Proxy Card”), will be mailed or made available on or about October 15, 2024 to all ADS holders, including banks, brokers and nominees, who are registered as holders of ADSs in the ADS register at 9:00 p.m. GMT (5:00 p.m. Eastern Time) on October 7, 2024 (the record date for ADS holders).

The duly completed ADS Proxy Cards submitted by the ADS holders of record must be received by Citibank, N.A. no later than 10:00 a.m. Eastern Time on October 25, 2024.

Section 656 of the Act

In circumstances where the value of the Company’s net assets is less than half of its called-up share capital (constituting a “serious loss of capital” under the Act), the Board is required, pursuant to section 656 of the Act, to convene a general meeting for the purpose of allowing shareholders to consider whether any, and, if so, what, steps should be taken to deal with the situation. As the General Meeting was already set to be convened, the Board does not believe it necessary to convene a separate general meeting to consider the serious loss of capital matter as it can be considered at the General Meeting. The Board welcomes dialogue with shareholders, and the General Meeting will provide a forum for such discussions to take place. The Board does not consider it necessary to propose a specific resolution in relation to the serious loss of capital and shareholders will not be asked to vote on this matter at the General Meeting.

The Board notes that the status of a “serious loss of capital” under section 656 of the Act imposes no immediate risk to the Company given the current strategy of the Company and the launch of fundraise which will make the Company solvent and make its balance sheet and cash position stronger. The Company intends the net proceeds of the Fundraise be predominantly used for sales and marketing and general corporate and administrative expenses. The serious of loss capital is a result of accounting adjustments made to impair the investment in the Company’s subsidiaries and intangibles due to prudent approach by the Board to justify the assets in the balance sheet at the year end.

2) Who can vote at the Meeting?

Ordinary shareholders

Only ordinary shareholders of record registered in the register of members at close of business (GMT) on October 29, 2024 will be entitled to vote at the Meeting. The holders of ordinary shares are entitled to one vote per share on all matters that are subject to a shareholder vote.

Beneficial owners of ordinary shares which are registered in the name of a broker, bank or nominee

The organization holding your account is considered the shareholder of record for purposes of voting at the Meeting. You are encouraged to provide voting instructions to your broker, bank or nominee so that they may submit a proxy.

ADS holders

You are entitled to exercise your vote as a holder of an interest in the capital of the Company represented by ADSs if you or your brokerage firm, bank or nominee is registered as a holder of ADSs in the ADS register maintained by Citibank, N.A. as of 9:00 p.m. GMT/ (5:00 p.m. Eastern Time) on October 7, 2024 (the record date for ADS holders).

Contacts at the Company

If at any point you require guidance, please contact Salim Hamir, Company Secretary, by telephone at +44 20 3139 2910.

3) What is the difference between an ordinary shareholder of record and a beneficial owner?

These terms describe how your ordinary shares are held. If your ordinary shares are registered directly in our register of members maintained by Link Group, our Registrar, you are a shareholder of record and the proxy materials are being sent directly, or otherwise being made available, to you. If your ordinary shares are held in the name of a broker, bank or other nominee, you are a beneficial owner of the shares held by your broker, bank or nominee and the proxy materials may be made available or forwarded to you by your broker, bank or other nominee, who is treated as the shareholder of record. As the beneficial owner, you may have the right to direct your broker, bank or other nominee on how to vote your ordinary shares by following the voting instructions provided to you by such broker, bank or other nominee.

4) What are the requirements to approve each of the resolutions?

You may cast your vote for or against each of the resolutions or abstain from voting your shares on one or more of these resolutions.

In accordance with the Company’s articles of association, voting on all resolutions at the General Meeting will be on a poll rather than a show of hands.

Resolutions 1 and 2 will be proposed as ordinary resolutions under English law. Assuming that a quorum is present, an ordinary resolution is passed on a poll if it is approved by holders representing a simple majority (more than 50%) of the total voting rights of shareholders present (in person or by proxy) who (being entitled to vote) vote on the resolution.

Resolution 3 will be proposed as a special resolution under English law. Assuming that a quorum is present, a special resolution is passed on a poll if it is approved by holders representing not less than 75% of the total voting rights of shareholders present (in person or by proxy) who (being entitled to vote) vote on the resolution.

4

5) What are the voting recommendations of our Board regarding the resolutions?

The following table summarizes the items that will be brought for a vote of our shareholders at the Meeting, along with the Board’s voting recommendations.

6) What constitutes a quorum?

Under our current articles of association, a quorum will be formed by two qualifying persons present at the meeting and between them holding at least 33 1/3 percent in number of the issued shares. A “qualifying person” is an individual who is a member, a person authorized to act as the representative of a member (being a corporation) in relation to the meeting or a person appointed as proxy of a member in relation to the meeting.

If you are an ordinary shareholder of record, your shares will be counted towards the quorum only if you are present in person or represented by proxy at the Meeting. If you are a beneficial owner of ordinary shares held in an account at a brokerage firm, bank or other similar organization your shares will be counted towards the quorum if your broker or nominee submits a proxy for those shares and the proxy represents the holder at the

5

Meeting. A member represented by a proxy at the Meeting will be counted towards the quorum requirement even where the proxy abstains from voting. If a form of proxy does not instruct the proxy how to vote, the proxy may vote as he or she sees fit or abstain in relation to any business of the Meeting.

Under our Articles of Association, if a quorum is not present within fifteen (15) minutes (or such longer interval as the chairman in his absolute discretion thinks fit) from the time appointed for holding the meeting, or if a quorum ceases to be present during the meeting, the meeting shall be dissolved if convened on the requisition of members. In any other case, the meeting shall stand adjourned to another time, date and place as may be fixed by the chairman of the Meeting (being not less than ten (10) clear days after the date of the original meeting).

7) How do I vote my shares?

Ordinary shareholders

If you are an ordinary shareholder of record, you may vote in person at the Meeting or if you do not wish to vote in person or will not be attending the Meeting, you may vote by proxy. You may appoint a proxy to vote on your behalf. Full details on how to appoint a proxy are set out in the notes to the Notice of General Meeting. If you properly give instructions as to your proxy appointment and your proxy appointment is not subsequently revoked, your shares will be voted in accordance with your instructions. If your ordinary shares are held in an account at a brokerage firm, bank, nominee or similar organization, you should follow directions provided by your broker, bank or other nominee.

All proxies must be lodged with our Registrar (Link Group) by no later than 12 noon BST (7:00 a.m. Eastern Time) on October 29, 2024.

You are encouraged to appoint the Chairman of the Meeting as your proxy.

ADS holders

If you are a holder of ADSs, you may exercise your right to vote by completing and submitting the ADS Proxy Card which will be sent, or made available, to you by Citibank, N.A. If your ADSs are held in an account at a brokerage firm, bank, nominee or similar organization, you should follow the directions provided by your broker, bank or other nominee. All ADS Proxy Cards, however submitted, must be received by Citibank, N.A. no later than 10:00 a.m. Eastern Time on October 25, 2024.

Citibank, N.A. will collate all votes properly submitted by ADS holders and submit a vote to the Company on behalf of all ADS holders.

8) How will my shares be voted if I do not specify how they should be voted?

If you submit your proxy electronically or via a hard copy form of proxy but do not indicate how you want your shares to be voted, your shares may be voted by the person that you appoint as your proxy as he or she deems fit or your proxy may abstain in relation to any business of the Meeting.

If you submit a signed ADS proxy card but it is missing voting instructions with respect to any resolution, Citibank, N.A. will deem the ADS holder to have instructed it to vote in favor of such resolution. In accordance with the terms of the deposit agreement by and among the Company, Citibank, N.A. as depositary and holders and beneficial owners of ADSs issued thereunder dated as of July 21, 2020 (the “Deposit Agreement”) and as amended and supplemented to date, holders of ADSs as of 9:00 p.m. GMT (5:00 p.m. Eastern Time) on October 7, 2024 (the record date for ADS holders) who do not provide the depositary with voting instructions on or before 10:00 a.m. Eastern Time on October 25, 2024 will be deemed to have instructed the depositary to give a discretionary proxy to a person designated by the Company to vote the underlying ordinary shares at the

6

Meeting, and such shares, if such discretionary proxy is given, will be voted in accordance with the Board of Directors’ recommendations; provided, however, that no such discretionary proxy shall be given by the depositary with respect to any matter to be voted upon as to which the Company informs the depositary that (a) the Company does not wish such proxy to be given, (b) substantial opposition exists, or (c) the rights of holders of deposited securities under the Deposit Agreement may be adversely affected.

If you are a beneficial owner of ADSs and your broker, bank or nominee does not receive instructions from you about how your ADSs are to be voted, such broker, bank or nominee may be permitted to vote your ADSs on your behalf, depending on the rules applicable to such broker, bank or nominee and the type of resolution. Under the rules of the New York Stock Exchange (“NYSE”), which are also applicable to Nasdaq-listed companies, brokers, banks and other securities intermediaries that are subject to the NYSE rules may use their discretion to vote your “uninstructed” ADSs on matters considered to be “routine” under NYSE rules, but they do not have discretionary power to vote your ADSs on “non-routine” matters. Therefore, brokers, banks and other nominees who hold ADSs on behalf of their beneficial owners may give a proxy to the Company to vote those ADSs with respect to each of the Resolutions and without specific voting instructions from such beneficial owners, as all of the matters to be voted upon at the Meeting are considered “routine” matters under the NYSE Rule 452 and brokers, banks and other nominees have discretionary voting power for such routine matters.

A “broker non-vote” refers to an ADS represented at the Meeting held by the holder of the underlying ordinary shares as to which instructions have not been received from the beneficial owner or person entitled to vote such shares and with respect to which, on one or more, but not all matters, the broker does not have discretionary voting power to vote such share because such matter is considered “non-routine” under the New York Stock Exchange rules.

We encourage you to submit your proxy with instructions and exercise your right to vote as a shareholder.

9) Can I change my vote or revoke a proxy?

An ordinary shareholder of record can revoke his or her proxy before the time of voting at the Meeting by:

If your ordinary shares are held in an account at a brokerage firm, bank, nominee or similar organization, you may be able to change or revoke your voting instructions by contacting the broker, bank or other nominee holding the shares or by your broker, bank or other nominee validly appointing you as proxy to attend at the Meeting. See also “What if I plan to attend the Meeting?”

If you hold ADSs, directly or through a broker, bank or other nominee, you must follow the instructions provided by Citibank, N.A. or such broker, bank or other nominee if you wish to change your vote. The last instructions you submit prior to the deadline indicated by Citibank, N.A. or the broker, bank or other nominee, as applicable, will be used to instruct Citibank, N.A. how to vote your ADSs.

7

10) Who counts the votes?

Link Group has been engaged as our independent agent to tabulate shareholder votes. If you are an ordinary shareholder of record, you can submit your proxy electronically (via the shareholder app or, if you are an institutional investor, the Proxymity platform) or request a hard copy form of proxy (see instructions set out in the notes to the Notice of General Meeting). A proxy may also be appointed by CREST members, by using the CREST electronic proxy appointment service, further details of which are set out in the notes to the Notice of General Meeting. Proxies submitted via CREST (under ID RA10) must be sent as soon as possible and in any event so as to be received by no later than 12 noon (GMT) on October 29, 2024, in order to be valid. If you hold your ordinary shares through a broker, please provide voting instructions to your broker.

If you are a registered holder of ADSs, you can return your executed ADS Proxy Card to Citibank, N.A. for tabulation. If you hold your ADSs through a broker, bank or other organization, that organization can return the ADS Proxy Card to Citibank, N.A. following your instruction. Citibank, N.A. will submit your votes to Link Group for tabulation.

11) How are votes counted?

Votes will be counted by Link Group, who will separately count “for” and “against” votes, and “votes withheld” or abstentions. A “vote withheld” or abstention is not a vote in law and will not be counted in the calculation of the votes “for” and “against” a resolution. Broker non-votes will have no effect on any resolution. Each Resolution to be voted on at the General Meeting is considered “routine” and accordingly we do not expect any broker non-votes.

12) How many votes do I have?

In accordance with the articles of association, voting on all resolutions at the General Meeting will be on a poll rather than a show of hands. On a poll, each shareholder present in person or by proxy or in the case of a corporation, by a duly authorized representative, has one vote for each voting ordinary share held by the ordinary shareholder. Each ADS of the Company represents two voting ordinary shares.

13) What if I plan to attend the Meeting?

Ordinary shareholders can attend the Meeting, but attendance will be limited to ordinary shareholders of record as of close of business (GMT) on October 29, 2024.

BACKGROUND TO RESOLUTION 1

On October 1, 2024, the Company announced that it had, successfully placed 131,161,556 new ordinary shares of £0.0025 each in the Company (“Ordinary Shares”) with certain Qualified Institutional Buyers (as defined in Rule 144A of the Securities Act of 1933, as amended (the “Securities Act”) and Company insiders at a placing price of 9 pence per new Ordinary Share (the “Issue Price”) raising aggregate gross proceeds of approximately £11.8 million (the “Fundraise”).

Pursuant to the Companies Act 2006, as amended (the “Companies Act”), our board of directors (the “Board” or “Directors”) may only allot shares (or grant rights to subscribe for or convert any security into shares) if authorized to do so by our shareholders (the “Shareholders”). The Companies Act also provides shareholders with pre-emptive rights when new shares are issued (or rights to subscribe for or convert any security into shares are granted) for cash; however, it is possible for the articles of association, or shareholders in a general meeting, to disapply preemptive rights.

On April 22, 2024, at our general meeting (the “April Meeting”) our Shareholders approved:

The remaining unutilized amount of the Allotment and Disapplication Authorities was not sufficient to allot and issue all of the shares that Company was looking to be issue.

Accordingly, the Board allotted and issued 24,007,773 Ordinary Shares (the “EIS/VCT Placing Shares”) without obtaining shareholder approval. The EIS/VCT Placing Shares are intended to attract tax relief pursuant to the UK Enterprise Investment Scheme (EIS) and/or qualify under the UK Venture Capital Trust scheme (VCT). The allotment and issue of the EIS/VCT Placing Shares took place on October 9, 2024.

The Company is now seeking authority to allot and issue 68,766,149 Ordinary Shares, all of which will be non-EIS/VCT qualifying (the “Non-EIS/VCT Placing Shares”), allot and issue 36,550,543 Ordinary Shares in return for the conversion of a certain proportion of the debt and accounts payable balance owed by the Company (the “Conversion Shares”) and allot and issue 38,387,634 Ordinary Shares, which will be used to satisfy the subscriptions by certain subscribers (the “Subscription Shares”) (the “Placing Shares”) and to issue $7,880,744 new unsecured convertible bonds as part of the restructuring of the £8.7 million amortizing senior convertible bonds held by a fund advised by Heights Capital Ireland LLC (the “New Convertible Bonds”), conditional upon the passing of Resolutions 1 and 3 set out in the Notice of General Meeting.

Resolution 1 will be proposed as an ordinary resolution to grant authority to the Board to allot the Placing Shares and the New Convertible Bonds.

Assuming that Resolution 1 is passed at the General Meeting and the Placing Shares and New Convertible Bonds are issued, the net proceeds of the Fundraise are expected to be used predominantly for sales and marketing and general corporate and administrative expenses of the Company.

10

Interest of Related Parties in this Resolution

James McCullough, Christopher Mills, Catherine Coste and Fergus Fleming (members of our Board) and Joel Jung (our Interim CFO), have subscribed for certain Placing Shares. Icahn School of Medicine at Mount Sinai has also subscribed for certain Subscription Shares. The number of Placing and Subscription Shares conditionally subscribed for by Mount Sinai and those above named persons, and their resulting shareholding after the Fundraise, are set out below:

We are asking you to approve Resolution 1, which the Board believes is in the best interests of Shareholders and most likely to promote the success of the Company for the benefit of its Shareholders as a whole. The full details of the resolutions are set forth below.

11

BACKGROUND TO RESOLUTION 2

Resolution 2 seeks to appoint Julian Baines, MBE, to the Board as a director of the Company, to be effective from the General Meeting subject to Nomad customary due diligence. Mr. Baines was the Non-Executive Chairman of the Company from March 2018 to June 2020. Christopher Mills currently Non-Executive Chairman intends to remain as a Non-Executive Director.

Julian Baines has significant experience in the life science industry and was the CEO of EKF Diagnostics Holdings plc (“EKF”) and BBI Holdings plc. Mr. Baines rejoined the executive team at EKF as Executive Chairman on a short-term basis in February 2023. Julian is also currently Non-Executive Chairman of Verici Dx plc. Before joining EKF, he undertook a management buyout at BBI in 2000, a flotation on AIM in 2004 and was responsible for selling the business to Alere Inc. (now part of Abbott Laboratories) in 2008 for c. £85 million. We believe that Mr. Baines is qualified to serve on our Board because of his previous experience as our Non-Executive Chairman, as well as his significant experience in the life sciences industry. Apart from his securityholdings set forth elsewhere in this proxy statement, Mr. Baines does not have any material interest in any transaction that would require disclosure pursuant to Item 404(a) of Regulation S-K. There is no understanding or arrangement between Mr. Baines and any other person or persons with respect to his appointment and there are no family relationships between Mr. Baines and any other director or executive officer or person nominated or chosen to become a director or executive officer.

12

BACKGROUND TO RESOLUTION 3

As of October 11, 2024 (being the latest practicable date before the circulation of this proxy statement) and following the allotment and issue of the EIS/VCT Placing Shares on October 9, 2024, the remaining unutilized amount of the Allotment and Disapplication Authorities which would permit the Company to allot shares, or grant rights to subscribe for or convert any security into shares, for cash on a non-pre-emptive basis is insufficient to allot and issue of the Second Tranche Placing Shares and the New Convertible Bonds.

Resolution 3 is intended to continue to give the Directors flexibility to act in the best interests of Shareholders, where the opportunity arises, by issuing new shares (or granting rights to subscribe for or convert any security into shares).

To ensure our continued ability to respond to market conditions and address business needs, the Board considers it appropriate that it be authorized under Resolution 3 to allot equity securities (within the meaning of section 560 of the Act) for cash pursuant to the authorities conferred by resolution 1 as if section 561 of the Act did not apply to such allotment, providing such authority is limited to: (i) the allotment of the Non-EIS/VCT Placing Shares with a maximum aggregate nominal amount of up to £171,915.373; (ii) the allotment of the Conversion Shares with a maximum aggregate nominal amount of up to £91,376.358; (iii) the allotment of the Subscription Shares with a maximum aggregate nominal amount of up to £95,969.085; (iv) $7,880,744 in relation to the issue of the New Convertible Bonds); and (v) in addition to (i) to (iv) (inclusive) the allotment equity securities with an aggregate nominal amount of up to £291,932.91 (representing approximately 35% of the Company’s issued share capital following the allotment of the Second Tranche Placing Shares (the “Enlarged Issued Share Capital”)).

The Directors consider it important that they are granted this authority to provide some flexibility in relation to the issue of shares on a non-pre-emptive basis. The Directors believe that it is important for the Board to have the flexibility to raise funds through the issue of new equity as required to finance the Company’s working capital requirements and growth plans.

The authority and the power described in Resolution 3 above is in substitution for the authority and power previously conferred on the Directors pursuant to the resolutions passed at April Meeting and will last to the earlier of (i) the conclusion of the annual general meeting of the Company to be held in 2024 and (ii) December 31, 2024.

We are asking you to approve this Resolution 3, which the Board believes is in the best interests of Shareholders and most likely to promote the success of the Company for the benefit of its Shareholders as a whole. The full details of the Resolutions are set forth below.

13

RESOLUTION 1:

AUTHORIZATION OF ALLOTMENT OF THE SECOND TRANCHE PLACING SHARES

Under the Companies Act, our Board of Directors cannot allot shares in the Company or grant rights to subscribe for, or convert any securities into, shares in the Company unless they are authorized to do so by the Company in general meeting. The current authorization of allotment of shares granted to the Board of Directors at the April Meeting is insufficient to allow the Board to allot and issue all of the Second Tranche Placing Shares.

Resolution 1 will be proposed as an ordinary resolution to grant authority to the Board to allot and issue the Non-EIS/VCT Placing Shares, the Conversion Shares, the Subscription Shares and the New Convertible Bonds. If approved by the Shareholders, this authority will (unless previously revoked or varied by the Company in general meeting) expire on the date three months from the passing of such resolution. If the Shareholders do not approve Resolution 1, the Company would not be able to allot and issue the Non-EIS/VCT Placing Shares, the Conversion Shares, the Subscription Shares and the New Convertible Bonds and will not receive the proceeds of the placing of the Non-EIS/VCT Placing Shares and the Subscription Shares and the benefits of the debt restructuring created by the issuing of the Conversion Shares and the New Convertible Bonds. If Resolution 1 is not passed, the placing of the Non-EIS/VCT Placing Shares, the Conversion Shares, the Subscription Shares and the New Convertible Bonds will not complete and the Board considers that it would be significantly constrained in its ability to fund the development of the Company’s business.

Vote Required

The affirmative vote of holders representing a simple majority of the total voting rights of Shareholders present in person or by proxy who (being entitled to vote) vote on the matter will be required to approve the authorization of allotment of the Second Tranche Placing Shares.

The Board of Directors recommends a vote

FOR the authorization of allotment of the Non-EIS/VCT Placing Shares, the Conversion Shares, the Subscription Shares and the New Convertible Bonds.

14

RESOLUTION 2:

APPOINTING JULIAN BAINES AS DIRECTOR OF THE COMPANY

Under the Companies Act, our Board of Directors require approval of our Shareholders to appoint a new director and we are seeking authorized to do so by the Company in general meeting.

Vote Required

The affirmative vote of holders representing a simple majority of the total voting rights of Shareholders present in person or by proxy who (being entitled to vote) vote on the matter will be required to approve the appointment of Julian Baines as a director of the Company.

15

RESOLUTION 3:

DISAPPLICATION OF PRE-EMPTION RIGHTS FOR THE SECOND TRANCHE PLACING

Resolution 3 seeks a disapplication of statutory pre-emption rights for the issue and allotment of the Non-EIS/VCT Placing Shares, the Conversion Shares and the Subscription Shares and the New Convertible Bonds.

Resolution 3 will be proposed as a special resolution. Resolution 3 provides that, subject to and conditional upon the passing of Resolution 1 (and in addition to all existing unexercised powers of the Directors under sections 570 and 571 of the Act, which shall continue in full force and effect), the Directors be empowered pursuant to section 571(1) of the Companies Act to allot the Non-EIS/VCT Placing Shares, the Conversion Shares and the Subscription Shares and the New Convertible Bonds, provided that such authority is limited to: (i) the allotment of the Non-EIS/VCT Placing Shares with a maximum aggregate nominal amount of up to £171,915.373; (ii) the allotment of the Conversion Shares with a maximum aggregate nominal amount of up to £91,376.358; (iii) the allotment of the Subscription Shares with a maximum aggregate nominal amount of up to £95,969.085; (iv) $7,880,744 in relation to the issue of the New Convertible Bonds); and (v) in addition to (i) to (iv) (inclusive) the allotment equity securities with an aggregate nominal amount of up to £291,932.91 (representing approximately 35% of the Enlarged Issued Share Capital). Such power shall expire (unless previously revoked or varied by the Company in general meeting) on the date three months after the date of passing of such resolution.

If the Shareholders do not approve Resolution 3, the Company will not be able to allot the Non-EIS/VCT Placing Shares, the Conversion Shares, the Subscription Shares and the New Convertible Bonds and the Company will not receive any proceeds from the Non-EIS/VCT Placing Shares and the Subscription Shares and the benefits of the debt restructuring created by the issuing of the Conversion Shares and the New Convertible Bonds. If Resolution 1 is not passed, the placing of the Non-EIS/VCT Placing Shares, the Conversion Shares, the Subscription Shares and the New Convertible Bonds will not complete and the Board considers that it would be significantly constrained in its ability to fund the development of the Company’s business.

Resolution 3 is conditional on the approval of Resolution 1 because English law requires that a pre-emption disapplication be given in respect of a particular authorization (general or specific) to allot shares. Resolution 3 will therefore not be passed unless Resolution 1 is also approved, notwithstanding that Shareholders may have voted to approve Resolution 3.

In accordance with section 571(6) of the Companies Act, (a) the reasons for the Directors’ recommendation to vote in favor of Resolution 3 are set out in this section and the section entitled “Background to Resolution 1”, (b) the amount of gross proceeds to be paid to the Company in connection with the allotment of the Non-EIS/VCT Placing Shares, the Conversion Shares, the Subscription Shares and the New Convertible Bonds is approximately £11.8 million and (c) the Directors believe that the proposed disapplication of pre-emption rights pursuant to Resolution 3 is necessary in order to enable the Company to carry out the Placing without incurring the substantial costs and delays that would be involved in a pre-emptive offering.

Vote Required

The affirmative vote of holders representing not less than 75% of the total voting rights of Shareholders present in person or by proxy who (being entitled to vote) vote on the matter will be required to approve the disapplication of pre-emption rights in respect of the allotment of the Second Tranche Placing Shares.

The Board of Directors recommends you vote

FOR the disapplication of pre-emption rights in respect of the allotment of the Second Tranche Placing Shares

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth certain information regarding the ownership of the Company’s ordinary shares (and our ADSs, each of which represents 2 ordinary shares) as of September 20, 2024 by: (i) each director; (ii) each of the named executive officers; (iii) all current executive officers and directors of the Company as a group; and (iv) all those known by the Company to be beneficial owners of more than five percent of its ordinary shares.

We have determined beneficial ownership in accordance with the rules and regulations of the SEC, and the information is not necessarily indicative of beneficial ownership for any other purpose. Except as indicated by the footnotes below, we believe, based on information furnished to us, that the persons and entities named in the table below have sole voting and sole investment power with respect to all shares that they beneficially own, subject to applicable community property laws.

This table is based upon information supplied by officers, directors and principal shareholders. Applicable percentage ownership is based on 165,925,513 ordinary shares, including ordinary shares in the form of ADSs, outstanding as of September 20, 2024. In computing the number of shares beneficially owned by a person and the percentage ownership of such person, we include all shares subject to options held by the person that are currently exercisable, or would be exercisable or would vest based on service-based vesting conditions as of November 19, 2024, which is 60 days after September 20, 2024. However, except as described above, we do not deem such shares outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the address for each beneficial owner listed in the table below is c/o Renalytix plc 2 Leman Street, London, United Kingdom.

DELIVERY OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for General Meeting materials with respect to two or more shareholders or ADS holders sharing the same address by delivering a single set of General Meeting materials addressed to those shareholders or ADS holders. This process, which is commonly referred to as “householding,” potentially means extra convenience for shareholders or ADS holders and cost savings for companies.

This year, a number of brokers with account holders who are our shareholders will be “householding” the Company’s proxy materials. A single set of General Meeting materials will be delivered to multiple shareholders or ADS holders sharing an address unless contrary instructions have been received from the affected shareholders or ADS holders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate set of General Meeting materials, please notify your broker or us. Please direct contact to us at Salim Hamir, Company Secretary, Renalytix plc, 2 Leman Street, London E1W 9US, United Kingdom or by telephone at +44 20 3139 2910. Shareholders or ADS holders who currently receive multiple copies of the General Meeting materials at their addresses and would like to request “householding” of their communications should contact their brokers.

EACH ORDINARY SHAREHOLDER IS URGED TO SUBMIT A PROXY.

EACH ADS HOLDER IS URGED TO COMPLETE, DATE, SIGN AND PROMPTLY RETURN

THE ADS PROXY CARD TO CITIBANK, N.A., THE DEPOSITARY FOR THE ADSs.

ADDITIONAL INFORMATION

Shareholders’ Rights to Call a General Meeting

Our shareholders have the right to call a meeting of our shareholders. The Companies Act generally requires the directors to call a general meeting once we have received requests to do so from shareholders representing at least 5% of our paid-up shares entitled to vote at a general meeting. The Companies Act prohibits shareholders of a U.K. public limited company from passing written resolutions. However, significant shareholders would, in any case, still have the power to call a general meeting and propose resolutions. These provisions are mandatory under the Companies Act and cannot be waived by our shareholders.

Shareholder Proposals for 2024 Annual General Meeting

Rule 14a-8 Proposals – Pursuant to Rule 14a-8 under the Exchange Act, in order to be considered for inclusion in our proxy statement for our 2024 annual general meeting of shareholders, shareholder proposals must be received by the Company at the Office of the Company Secretary, 2 Leman Street, London E1W 9US, United Kingdom no later than 120 days before the anniversary of the date on which we sent or published our proxy materials for the 2023 AGM (or July 16, 2024). However, if the date of the 2024 annual general meeting is more than 30 calendar days from the date of the anniversary of the 2023 AGM, then the notice must be received by our Company Secretary a reasonable time before we begin to print and send our proxy materials.

Other Proposals – Shareholders intending to include a proposal on the agenda for the 2024 annual general meeting of shareholders, irrespective of whether they intend to have the proposal included in our proxy statement, must comply with the requirements under our articles of association and English law. Under section 338 of the Companies Act, shareholders representing at least 5% of holders entitled to vote on a resolution at an annual general meeting may require the Company to include such resolution in its notice of an annual general meeting. Provided the applicable thresholds are met, notice of the resolution must be received by the Company at the Office of the Company Secretary, 2 Leman Street, London E1W 9US, United Kingdom at least six weeks prior to the date of the annual general meeting, or, if later, at the time notice of the annual general meeting is delivered to shareholders.

To comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees other than the Company’s nominees must provide notice at our principal executive offices that sets forth the information required by Rule 14a-19 under the Exchange Act no later than 60 days prior to the anniversary of the 2023 AGM (or October 16, 2024).

Proposals and nominations that are not received by the dates specified above, or otherwise do not meet all relevant requirements, will be considered untimely or improper, as applicable. We also encourage anyone sending in a shareholder proposal to additionally send such proposals via email to Salim Hamir, Company Secretary (shamir@renalytix.com).

Renalytix plc (the “Company”)

The undersigned holder, as of the ADS Record Date, of the American Depositary Share(s) issued under the Deposit Agreement (“ADSs”) and identified above, acknowledges receipt of a copy of the Depositary’s Notice of General Meeting and hereby authorizes and directs the Depositary to cause to be voted at the Meeting (and any adjournment or postponement thereof) the Deposited Securities represented by the ADSs in the manner indicated on the reverse side hereof. All capitalized terms not defined herein shall have the meaning given to such term in the Deposit Agreement. The information with respect to the Meeting and the ADS Voting Instructions contained herein and in any related materials may change after the date hereof as a result of a change in circumstances (e.g., an adjournment or cancellation of the Meeting, and change in manner of holding the Meeting). The Company intends to announce any changes and updates only on its website https://www.renalytix.com. We encourage you to check the referenced Company website for any updates to the information with respect to the Meeting and the ADS Voting Instructions as it is not expected that any additional information will be distributed to you via mail or email.

Voting instructions may be given only in respect of a number of ADSs representing an integral number of Deposited Securities. Upon the timely receipt from a Holder of ADSs as of the ADS Record Date of voting instructions in the manner specified by the Depositary, the Depositary shall endeavor, insofar as practicable and permitted under any applicable law, the provisions of the Deposit Agreement, the Articles of Association of the Company and the provisions of the Deposited Securities, to vote, or cause the Custodian to vote, the Deposited Securities (in person or by proxy) represented by such Holder’s ADSs in accordance with the voting instructions received from the Holder of the ADSs. If the Depositary does not receive voting instructions from a Holder as of the ADS Record Date on or before the date established by the Depositary for such purpose, such Holder shall be deemed, and the Depositary shall deem such Holder, to have instructed the Depositary to give a discretionary proxy to a person designated by the Company to vote the Deposited Securities; provided, however, that no such discretionary proxy shall be given by the Depositary with respect to any matter to be voted upon as to which the Company informs the Depositary that (i) the Company does not wish such proxy to be given, (ii) suGMTantial opposition exists, or (iii) the rights of holders of Deposited Securities may be adversely affected.

Deposited Securities represented by ADSs for which no timely voting instructions are received by the Depositary from the Holder shall not be voted (except as otherwise contemplated in the Deposit Agreement). Neither the Depositary nor the Custodian shall under any circumstances exercise any discretion as to voting and neither the Depositary nor the Custodian shall vote, attempt to exercise the right to vote, or in any way make use of, for purposes of establishing a quorum or otherwise, the Deposited Securities represented by ADSs, except pursuant to and in accordance with the voting instructions timely received from Holders or as otherwise contemplated in the Deposit Agreement. If the Depositary timely receives voting instructions from a Holder which fail to specify the manner in which the Depositary is to vote the Deposited Securities represented by such Holder’s ADSs, the Depositary will deem such Holder to have instructed the Depositary to vote in favor of the items set forth in such voting instructions.

Please indicate on the reverse side hereof how the Deposited Securities are to be voted. 

The Voting Instructions must be marked, signed and returned on time in order to be counted.
