Renalytix Plc

("Renalytix" or the "Company")

Proposed Fundraise

Renalytix plc (LSE: RENX) (OTCQB: RNLXY), a precision medicine company with kidneyintelX.dkd, the only FDA-approved and Medicare reimbursed prognostic test to support early-stage risk assessment in chronic kidney disease, today announces its intention to raise a minimum of £4.0 million gross proceeds through a placing ("Placing") and a subscription ("Subscription") (together, the "Fundraise") of new ordinary shares of £0.0025 each in the capital of the Company ("Ordinary Shares") and a separate retail offer of new Ordinary Shares (the "Retail Offer") via the Winterflood Retail Access Platform (the "WRAP")at an issue price of 9.5 pence per new Ordinary Share (the "Issue Price") to new and existing institutional and other investors. Oberon Capital (a trading name of Oberon Investments Limited) is acting as sole bookrunner on the Placing.

The Placing will be effected by way of an accelerated bookbuild (the "Bookbuild"), which will open with immediate effect, and the Placing is subject to the terms and conditions set out in Appendix I to this announcement (which forms part of this announcement, such announcement and Appendix I together being the "Announcement").  A further announcement confirming the closing of the Bookbuild and the aggregate number of new Ordinary Shares to be issued pursuant to the Placing and the Subscription is expected to be made in due course.

The Issue Price represents a discount of 11.6 per cent. to the closing middle market price of 10.75 pence per Ordinary Share on 19 September 2025, and a premium of 39 per cent. to the Company's 90 day closing average share price, as of the last business day prior to this Announcement.

At the annual general meeting of the Company held on 19 December 2024, allotment and disapplication of pre-emption rights authorities were obtained which enable the Directors to issue and allot new Ordinary Shares for cash up to a maximum aggregate nominal amount of £289,805.26 (representing 115,922,104 new Ordinary Shares in the capital of the Company) (the "AGM Authorities"). These AGM Authorities will be sufficient for the proposed Fundraise and will be used for the purposes of issuing any new Ordinary Shares pursuant to the Fundraise. Consequently, the Company would not need to obtain further authorities to issue and allot new Ordinary Shares in the Fundraise on a non-pre-emptive basis.

In addition, certain Directors (the "Directors"), intend to participate in the Fundraise. It is intended that the Directors' participation will comprise approximately £270,000, in aggregate, through the issue of approximately 2.84 million new Ordinary Shares at the Issue Price.  The Directors participating in the Fundraise will be subject to a 6 month lock-in period. Further details will be announced as appropriate in due course. 

Placing Highlights

Use of proceeds from Fundraise

On 15 September 2025 the Company announced that it had signed a collaboration agreement with Tempus. The collaboration will make the Company's kidneyintelX.dkd prognostic blood testing more widely available for eligible patients within its US network of healthcare institutions. Eligible patients have type 2 diabetes with chronic kidney disease, impacting nearly 15 million individuals in the US.

Renalytix's kidneyintelX.dkd will be the first test offered in Tempus' portfolio in the chronic kidney disease category, indicated for use as an aid in predicting level of risk (high, moderate, low) for progressive decline in kidney function in type 2 diabetes patients with diagnosed chronic kidney disease stages 1-3b.

The agreement with Tempus is a significant milestone for the Company pursuant to which Tempus and Renalytix will collaborate with US health systems to make testing more available for providers to order within existing clinical workflows.  

The Company will therefore use the net proceeds of the Fundraise to support the collaboration with Tempus and ensure the effective integration of kidneyintelX.dkd into Tempus' portfolio in the chronic kidney disease category.

Placing

The Ordinary Shares being issued pursuant to the Placing are to UK investors only. The Placing Shares are subject to certain conditions set out in Appendix I to this Announcement.

Subscription

Ordinary Shares issued pursuant to the Subscription to investors in the U.S. will be issued pursuant to an exemption from registration with the U.S. Securities and Exchange Commission (the "SEC").

Pursuant to the Subscription Agreements, the Subscribers have agreed to subscribe for the Subscription Shares at the Issue Price.

The Subscription Shares, when issued, will be fully paid and will rank pari passu in all respects with the existing Ordinary Shares in issue. It is expected that the Subscription Shares will be issued on or around 29 September 2025.

The Retail Offer

The Directors value the Company's retail investor base and believe that it is appropriate to provide private and other investors with an opportunity to participate in the Fundraise alongside institutional investors. The Company therefore intends to open this opportunity to individual investors through WRAP and further announcements will be made shortly in connection with the Retail Offer. For the avoidance of doubt, the Retail Offer is not part of the Placing and is the sole responsibility of the Company. Oberon and SP Angel have no responsibilities, obligations, duties or liabilities (whether arising pursuant to any contract, law, regulation, or tort) in relation to the same.

Admission to AIM

Application will be made to the London Stock Exchange for Admission of the Placing Shares and the Subscription Shares to trading on AIM. It is expected that Admission of  Placing Shares will become effective and that dealings in the Placing Shares with the First Tranche Placing Shares admission commencing at 8.00 a.m. on 26 September 2025.

Information regarding the Admission of the shares that are to be issued pursuant to the Retail Offer will be provided in due course.

The person responsible for arranging for the release of this Announcement on behalf of Renalytix is James McCullough, CEO.

About Renalytix

Renalytix (LSE: RENX) (OTCQB: RNLXY) is an artificial intelligence-enabled in vitro diagnostics company, focused on optimizing clinical management of kidney disease to drive improved patient outcomes. Renalytix has received FDA approval and Medicare reimbursement for kidneyintelX.dkd which is now offered commercially in the United States.

Unrecognized and uncontrolled kidney disease remains one of the largest barriers to controlling cost and suffering in the United States and the United Kingdom's medical system, affecting over 14 million and 8 million people, respectively. After five years of development and clinical validation, kidneyintelX.dkd is the only FDA-approved and Medicare reimbursed prognostic tool capable of understanding a patient's risk with kidney disease early where treatment has maximal effect. kidneyintelX.dkd is now being deployed across large physician group practices and health systems in select regions of the United States.

The over 15,000 patients that have been tested by kidneyintelX.dkd have produced a substantial body of real-world performance data. In patient populations where kidneyintelX.dkd has been deployed, a demonstrated and significant increase in diagnosis, prognosis, and treatment rates have been recorded. kidneyintelX.dkd now has full reimbursement established by Medicare, the largest insurance payer in the United States, at $950 per reportable result. kidneyintelX.dkd is also recommended for use in the international chronic kidney disease clinical guidelines ("KDIGO").

Bookbuild

The Bookrunner will today commence an accelerated bookbuilding process to determine demand for participation in the Placing by potential Placees. The Bookrunner and the Company shall be entitled to effect the Placing by such alternative method to the Bookbuild as they may, in their sole discretion determine.

Details of the Placing

The Bookrunner has entered into the Placing Agreement with the Company under which the Bookrunner has agreed, on the terms and subject to the conditions set out therein, to undertake to use its reasonable endeavours to procure, as the Company's placing agent and bookrunner for the purpose of the Placing, subscribers for the Placing Shares at the Placing Price.

The final number of Placing Shares will be decided at the close of the Bookbuild following the execution of the terms of the Placing by the Company and the Bookrunner (the "Placing Term Sheet").

The Placing Agreement contains customary undertakings and warranties given by the Company to the Bookrunner including as to the accuracy of information contained in this Announcement and to be contained in the Placing Document, to matters relating to the Company and its business and a customary indemnity given by the Company to the Bookrunner in respect of liabilities arising out of or in connection with the Placing and/or the First Admission and/or the Second Admission (if applicable).

The Placing is conditional upon, inter alia:

The number of Placing Shares will be determined following completion of the Bookbuild as set out in this Announcement.

The Placing Shares will, as from the date when they are issued, be fully paid or credited as fully paid and will rank pari passu in all respects with the existing issued Ordinary Shares, including the right to receive all dividends and other distributions declared (if any), made or paid on or in respect of the Ordinary Shares after the relevant date of issue of the Placing Shares.

Lock up

As part of the Placing, the Company has agreed that it will not issue or sell any Ordinary Shares for a period of 90 days after the date of this announcement without the prior written consent of the Bookrunner (not to be unreasonably withheld or delayed).  That agreement is subject to certain customary carve-outs agreed between the Bookrunner and the Company.

Enterprise Investment Scheme ("EIS") and Venture Capital Trusts ("VCT")

The EIS/VCT Placing Shares to be issued pursuant to the Placing are intended to rank as "eligible shares" for the purposes of EIS and VCT investors and a "qualifying holding" for the purposes of an investment by VCTs, each pursuant to the relevant respective sections of the Income Tax Act 2007 (the "VCT Legislation").

The Company has obtained a written opinion from specialist tax advisers confirming that the EIS/VCT Placing Shares will rank as "eligible shares" for the purposes of the EIS and will be capable of being a "qualifying holding" for the purposes of VCT Legislation. However, no assurance has been obtained from HMRC that the Company is a qualifying company for the purposes of the EIS or that a subscription for EIS/VCT Placing Shares is a qualifying holding.

The status of the EIS/VCT Placing Shares as a qualifying holding for EIS and VCT purposes respectively will be conditional (amongst other things) on the qualifying conditions being satisfied throughout the period of ownership. There can be no assurance that the Company will conduct its activities in a way that will secure or retain qualifying status for VCT and/or EIS purposes (and indeed circumstances may arise where the Directors of the Company believe that the interests of the Company and the Group are not served by seeking to retain such status).

Neither the Company nor the Directors have given any warranties or undertakings that EIS reliefs or VCT reliefs will be granted in respect of the EIS/VCT Placing Shares. Neither the Company nor the Directors have given any warranties or undertakings that EIS reliefs or VCT reliefs, if granted, will not be withdrawn.

Application for admission to trading

Application will be made to the London Stock Exchange for the First Admission and the Second Admission respectively. It is expected that settlement of the First Tranche Placing Shares will take place on or around 26 September 2025 and First Admission will become effective and dealings in the First Tranche Placing Shares will commence at that time. It is expected that settlement of the Second Tranche Placing Shares will take place within one trading day of First Admission and that the Second Admission will become effective and dealings in the Second Tranche Placing Shares will commence at that time.

Neither the Bookrunner or the Company, nor any of their respective affiliates, agents, directors, officers, consultants or employees, shall have any liability to any Placee (or to any other person whether acting on behalf of a Placee or otherwise) in respect of any decision they may make as to whether or not to waive or to extend the time and/or date for the satisfaction of any condition to the Placing nor for any decision they may make as to the satisfaction of any condition or in respect of the Placing generally and by participating in the Placing each Placee agrees that any such decision is within the absolute discretion of the Bookrunner.

Following First Admission, the Placing Agreement will not be capable of termination or rescission by any party to it in so far as it relates to the Placing of the EIS/VCT Placing Shares and, following Second Admission, the Placing Agreement will not be capable of termination or rescission by any party in so far as it relates to the Placing of the Second Tranche Placing Shares.

The rights and obligations of the Placees shall terminate only in the circumstances described in these terms and conditions and in the Placing Agreement and will not be subject to termination by the Placee or any prospective Placee at any time or in any circumstances.  By participating in the Placing, Placees agree that the exercise by the Bookrunner of any right of termination or other discretion under the Placing Agreement shall be within the absolute discretion of the Bookrunner, and that it need not make any reference to Placees and that it shall have no liability to Placees whatsoever in connection with any such exercise or decision not to exercise.  Placees will have no rights against the Bookrunner, the Company or any of their respective directors or employees under the Placing Agreement pursuant to the Contracts (Rights of Third Parties) Act 1999 (as amended).

The Placing Shares are being offered to a limited number of specifically invited persons only and will not be offered in such a way as to require an admission document or prospectus in the United Kingdom or in any other jurisdiction.  No offering document, admission document or prospectus has been or will be submitted to be approved by the FCA or submitted to the London Stock Exchange in relation to the Placing, and Placees' commitments will be made solely on the basis of the information contained in the Announcement (including the Appendices) and the UK Public Information.  Each Placee, by accepting a participation in the Placing, agrees that the content of this Announcement is exclusively the responsibility of the Company and confirms that it has neither received nor relied on any other information (other than the UK Public Information), representation, warranty, or statement made by or on behalf of the Company, the Bookrunner, or any other person and neither the Bookrunner, the Company nor any other person will be liable for any Placee's decision to participate in the Placing based on any other information, representation, warranty or statement which the Placees may have obtained or received and, if given or made, such information, representation, warranty or statement must not be relied upon as having been authorised by the Bookrunner, the Company, or their respective officers, directors, consultants, employees or agents. Each Placee acknowledges and agrees that it has relied on its own investigation of the business, financial or other position of the Company in accepting a participation in the Placing. Neither the Company nor the Bookrunner is making any undertaking or warranty to any Placee regarding the legality of an investment in the Placing Shares by such Placee under any legal, investment or similar laws or regulations. Each Placee should not consider any information in this Announcement to be legal, tax or business advice. Each Placee should consult its own solicitor, tax adviser and financial adviser for independent legal, tax and financial advice regarding an investment in the Placing Shares. Nothing in this paragraph shall exclude the liability of any person for fraudulent misrepresentation.

Registration and settlement

Provided payment in full has been made, definitive legended share certificate(s) in respect of the Placing Shares shall be prepared by MUFG Group (the "Registrar") as soon as possible following the First Admission or Second Admission, as applicable.  Interest is chargeable daily on payments not received from Placees on the due date in accordance with the arrangements set out above at the rate of two percentage points above the Sterling Overnight Index Average (SONIA) as determined by the Bookrunner.

Each Placee is deemed to agree that, if it does not comply with these obligations, the Bookrunner may sell any or all of the Placing Shares allocated to that Placee on such Placee's behalf and retain from the proceeds, for the Bookrunner's account and benefit (as agent for the Company), an amount equal to the aggregate amount owed by the Placee plus any interest due. The relevant Placee will, however, remain liable and shall indemnify the Bookrunner (as agent for the Company) on demand for any shortfall below the aggregate amount owed by it and may be required to bear any stamp duty or stamp duty reserve tax or securities transfer tax (together with any interest or penalties) which may arise upon the sale of such Placing Shares on such Placee's behalf.  By communicating a bid for Placing Shares to the Bookrunner, each Placee confers on the Bookrunner all such authorities and powers necessary to carry out any such sale and agrees to ratify and confirm all actions which the Bookrunner lawfully takes in pursuance of such sale.

If Placing Shares are to be delivered to a custodian or settlement agent, Placees should ensure that the trade confirmation or contract note is copied and delivered immediately to the relevant person within that organisation.

Insofar as Placing Shares are registered in a Placee's name or that of its nominee or in the name of any person for whom a Placee is contracting as agent or that of a nominee for such person, such Placing Shares should, subject as provided below, be so registered free from any liability to UK stamp duty or stamp duty reserve tax or securities transfer tax. Placees will not be entitled to receive any fee or commission in connection with the Placing.

Representations, warranties and further terms

By participating in the Placing each Placee (and any person acting on such Placee's behalf) makes the following representations, warranties, acknowledgements, agreements and undertakings (as the case may be) to the Company and the Bookrunner, namely that, each Placee (and any person acting on such Placee's behalf):

The representations, warranties, acknowledgments and undertakings contained in this Appendix are given to the Bookrunner and the Company and are irrevocable and shall not be capable of termination in any circumstances.

The agreement to settle a Placee's subscription (and/or the subscription of a person for whom such Placee is contracting as agent) free of stamp duty and stamp duty reserve tax depends on the settlement relating only to a subscription by it and/or such person direct from the Company for the Placing Shares in question.  Such agreement assumes that the Placing Shares are not being subscribed for in connection with arrangements to issue depositary receipts or to transfer the Placing Shares into a clearance service.  If there are any such arrangements, or the settlement relates to any other subsequent dealing in the Placing Shares, stamp duty or stamp duty reserve tax may be payable, for which neither the Company or the Bookrunner will be responsible, and the Placee to whom (or on behalf of whom, or in respect of the person for whom it is participating in the Placing as an agent or nominee) the allocation, allotment, issue or delivery of Placing Shares has given rise to such UK stamp duty or stamp duty reserve tax undertakes to pay such UK stamp duty or stamp duty reserve tax forthwith and to indemnify on an after-tax basis and to hold harmless the Company and the Bookrunner in the event that any of the Company or the Bookrunner has incurred any such liability to UK stamp duty or stamp duty reserve tax.  If this is the case, each Placee should seek its own advice and notify the Bookrunner accordingly.

In addition, Placees should note that they will be liable for any stamp duty and all other stamp, issue, securities, transfer, registration, documentary or other duties or taxes (including any interest, fines or penalties relating thereto) payable outside the UK by them or any other person on the subscription by them of any Placing Shares or the agreement by them to subscribe for any Placing Shares.

Each Placee, and any person acting on behalf of the Placee, acknowledges that the Bookrunner does not owe any fiduciary or other duties to any Placee in respect of any representations, warranties, undertakings or indemnities in the Placing Agreement.

When a Placee or person acting on behalf of the Placee is dealing with the Bookrunner, any money held in an account with the Bookrunner on behalf of the Placee and/or any person acting on behalf of the Placee will not be treated as client money within the meaning of the rules and regulations of the FCA made under the FSMA.  The Placee acknowledges that the money will not be subject to the protections conferred by the client money rules; as a consequence, this money will not be segregated from the Bookrunner's money in accordance with the client money rules and will be used by the Bookrunner in the course of its own business and the Placee will rank only as a general creditor of the Bookrunner.

All times and dates in this Announcement may be subject to amendment.  The Bookrunner shall notify the Placees and any person acting on behalf of the Placees of any changes.

Past performance is no guide to future performance and persons needing advice should consult an independent financial adviser.
