NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (Unaudited)

The Company is subject to risks and uncertainties common to early-stage companies in the diagnostics industry, including, but not limited to, ability to secure additional capital to fund operations, compliance with governmental regulations, development by competitors of new technological innovations, dependence on key personnel and protection of proprietary technology. To achieve widespread usage, KidneyIntelX and additional diagnostic products currently under development will require extensive clinical testing and validation prior to regulatory approval and commercialization. These efforts require significant amounts of additional capital, adequate personnel, and infrastructure, and extensive compliance-reporting capabilities.

---

During the three and nine months ended March 31, 2024, the Company recognized $0.04 million of pharmaceutical services revenue where performance obligations are satisfied at a point in time.

Item 2. Management’s Discussion and Analysis of Financial Condition and Results of Operations.

You should read the following discussion and analysis of our financial condition and results of operations in conjunction with our unaudited consolidated financial statements and related notes thereto included in Part I, Item 1 of this Quarterly Report on Form 10-Q, our audited consolidated financial statements and related notes for the year ended June 30, 2023, included in our Annual Report on Form 10-K filed with the Securities and Exchange Commission (the “SEC”) on September 28, 2023 (the “Annual Report on Form 10-K”), as well as the information contained under Management’s Discussion and Analysis of Financial Condition and Results of Operations and "Risk Factors" contained in the Annual Report on Form 10-K, and Part II, Item 1A "Risk Factors" of this Quarterly Report on Form 10-Q, and other information provided from time to time in our other filings with the SEC.

Overview

Renalytix is focused on providing doctors around the world with a safe, reliable and effective tool to identify which patients are or are not in danger of losing significant kidney function and falling into kidney failure and may require long-term dialysis or kidney transplant. Chronic kidney disease is one of the largest urgent medical needs, globally affecting an estimated 850 million people, and is responsible for an unsustainable and growing societal cost burden.

We believe an important part of the answer is preventative medicine and the ability to identify individuals with advancing chronic kidney disease early, where new drug therapies and clinical strategies have the optimal chance to stop uncontrolled disease progression.

At Renalytix, we developed kidneyintelX.dkd, the first U.S. Food and Drug Administration ("FDA"), authorized in vitro prognostic test that uses an artificial intelligence-enabled algorithm to aid in assessment of the risk of progressive decline in kidney function. The test is designed to predict early in the progression of kidney disease who is at risk for significant sustained decline in kidney function. Prognostic tests, such as kidneyintelX.dkd, are not intended for diagnosing any disease or for monitoring disease progression or the effect of any therapeutic product. Rather, prognostic tests are intended to be used in conjunction with other clinical and diagnostic findings and consistent with professional standards of practice, including information obtained by alternative methods, and clinical evaluation, as appropriate. When used as intended, potential interventions can be considered early, ideally before major damage is done and when treatments can be most effective. KidneyintelX.dkd is part of a family of clinical tests being developed from the KidneyIntelX technology platform developed using technology licensed from the Icahn School of Medicine at Mount Sinai in New York, the Joslin Diabetes Center in Boston and under development through U.S. and international collaborations.

We are deploying KidneyIntelX to patient populations with DKD on a regional basis through partnerships with healthcare systems and insurance payors that provide coverage to those healthcare systems’ patients. Following the receipt of national Medicare pricing at $950 per reportable test for KidneyIntelX in January 2020, we are actively pursuing Medicare coverage and a determination under the MolDX Program. In March 2020, we announced that our application for a Medicare PTAN was approved by Noridian Healthcare Solutions, the regional Medicare Administrative Contractor with responsibility for overseeing facilities and providers located in the western United States, and, as a result, we are now qualified as a provider and can bill for services provided to patients with Medicare and Medicaid health insurance coverage in the United States. In addition, in October 2019, Capital District Physicians’ Health Plan, Inc., a physician-led health insurance payor in New York, adopted coverage determination policies that provide insurance for certain patients with DKD who are tested with KidneyIntelX. We are working with additional private insurance payors and healthcare providers to expand insurance coverage for KidneyIntelX nationwide, which we believe will be accelerated by our recent achievement of a CPT code and national Medicare pricing.

Since our inception in March 2018, we have focused primarily on organizing and staffing our company, raising capital, developing the KidneyIntelX platform, conducting clinical validation studies for KidneyIntelX, establishing and protecting our intellectual property portfolio and commercial laboratory operations, pursuing regulatory approval and developing our reimbursement strategy. We have funded our operations primarily through equity and debt financings.

Macroeconomic Considerations

During fiscal year 2023, we returned to conducting business as usual after the COVID-19 pandemic, with necessary or advisable modifications to employee travel and employee work locations. We continue to monitor the situation related to COVID-19 and may take actions that alter our business operations to the extent that may be required by federal, state or local authorities, or that we determine are in the best interests of our employees, partners and shareholders.

---

Unfavorable conditions in the economy in the United States and abroad may negatively affect the growth of our business and our results of operations. For example, macroeconomic events, including the COVID-19 pandemic, rising inflation and U.S. and U.K. interest rates and the Russia-Ukraine and Hamas-Israel armed conflicts and related developments, have led to economic uncertainty globally. The effect of macroeconomic conditions may not be fully reflected in our results of operations until future periods. If, however, economic uncertainty increases or the global economy worsens, our business, financial condition and results of operations may be harmed. For further discussion of the potential impacts of macroeconomic events on our business, financial condition, and operating results, see the section titled “Risk Factors.”

Our Key Agreements

Mount Sinai Health System

In May 2018, we entered into the Mount Sinai Agreement, with Mount Sinai, pursuant to which we obtained a worldwide, royalty-bearing, exclusive license under certain patents and a worldwide, royalty-bearing, non-exclusive license under certain know-how of Mount Sinai to develop and commercialize licensed products in connection with the application of artificial intelligence for the diagnosis of kidney disease. Pursuant to the terms of the Mount Sinai Agreement, we are obligated to use commercially reasonable efforts in connection with the development and commercialization of the licensed products, including in accordance with specified diligence milestones.

We paid Mount Sinai $10.0 million as an up-front payment upon entering into the Mount Sinai Agreement. Under the terms of the Mount Sinai Agreement, we are obligated to pay Mount Sinai $1.5 million and $7.5 million in commercial milestone payments upon achieving worldwide net sales of KidneyIntelX of $50.0 million and $300.0 million, respectively. We are also obligated to pay Mount Sinai a 4% to 5% royalty on net sales of KidneyIntelX, subject to customary reductions. Royalties are payable on a product-by-product basis from first commercial sale of such product until the later of (1) expiration of the last valid claim of a licensed patent covering such product or (2) on a country-by-country basis, 12 years from first commercial sale of such product in such country. Moreover, we are obligated to pay Mount Sinai between 15% and 25% of any consideration received by us from a sublicensee. The two provisional patent applications covering the KidneyIntelX diagnostic in-licensed under the Mount Sinai Agreement were filed in February 2020 and April 2020, respectively. If issued, these patents will expire in February 2041 and April 2041, respectively. Furthermore, we agreed to carry out and fund a clinical utility study for KidneyIntelX at a total estimated cost of $10.7 million.

The Mount Sinai Agreement expires on the later of the tenth anniversary of the execution of the agreement and expiration of the last remaining royalty term. We may terminate the Mount Sinai Agreement at any time upon 90 days’ prior written notice. Mount Sinai may terminate the agreement for our uncured material breach, our failure to meet certain diligence milestones, our insolvency, or in the event that we challenge the validity or enforceability of any licensed patent.

Joslin Diabetes Center

In July 2017, EKF entered into the Joslin Agreement, with Joslin. In October 2018, we purchased all of EKF’s rights, title, interest and benefit in the Joslin Agreement in exchange for the issuance of 15.4 million of our ordinary shares.

Pursuant to the Joslin Agreement and the related assignment from EKF, we obtained a worldwide, royalty- bearing, exclusive license under any patents and any related know-how of Joslin related to the patent application filed with respect to the Joslin IP to make, have made, use, offer for sale and sell licensed products covered by claims in the Joslin IP, and to perform, practice offer for sale and sell certain licensed processes related to the Joslin IP. We are obligated to use commercially reasonable efforts in connection with the development and commercialization of the licensed products and licensed processes, including in accordance with a development plan.

Under the terms of the Joslin Agreement, we are obligated to pay Joslin aggregate commercial milestone payments of $0.3 million and $1.0 million in commercial milestone payments upon achieving worldwide net sales of licensed products and processes of $2.0 million and $10.0 million, respectively. We are also obligated to pay Joslin a 5% royalty on net sales of any licensed products or licensed processes, subject to customary reductions. Moreover, we are obligated to pay Joslin 25% of any consideration received by us from a sublicensee.

The Joslin Agreement initially expires on July 31, 2025, and is subject to an automatic five-year extension unless either party notifies the other party of its intent not to extend the agreement at least 180 days prior to initial expiration. Either party may terminate the Joslin Agreement earlier upon an uncured material breach of the agreement by the other party, the insolvency of the other party, or in the event the other party is unable to perform its obligations under the agreement for a specified period. Additionally, Joslin may terminate the agreement in the event that we cease developing or commercializing licensed products or processes, if we fail to maintain certain required insurance policies, and if we fail to pay patent expenses related to the licensed patents.

Recent Developments

NASDAQ Notices

On December 22, 2023, we received two written notices from The Nasdaq Stock Market, or Nasdaq, notifying us that (i) because the closing bid price for our ADSs was below $1.00 per ADS for at least 30 consecutive business days, we did not meet the $1.00 per ADS minimum bid price requirement of Nasdaq Listing Rule 5450(a)(1) the (“Minimum Bid Price Requirement”) and (ii) we are not in compliance with the requirement to maintain a minimum market value of listed securities (the “MVLS”) of $50,000,000 for continued listing on The Nasdaq Global Market, as set forth in Nasdaq Listing Rule 5450(b)(2)(A) (the “MVLS Requirement”).

The Notices have no immediate impact on the continued listing or trading of our ADSs on The Nasdaq Global Market, which will continue to be listed and traded on The Nasdaq Global Market, subject to our compliance with the other continued listing requirements.

Pursuant to Nasdaq Listing Rule 5810(c)(3)(A) and Nasdaq Listing Rule 5810(c)(3)(C), we have a compliance period of 180 calendar days, or until June 19, 2024 (the “Compliance Period”), to regain compliance with the Minimum Bid Price Requirement and the MVLS Requirement. To regain compliance with the Minimum Bid Price Requirement, the closing bid price of the ADSs must be at least $1.00 per ADS for a minimum of ten consecutive business days prior to the end of the Compliance Period. To regain compliance with the MVLS Requirement, our MVLS must close at $50,000,000 or more for a minimum of ten consecutive business days prior to the end of the Compliance Period.

If we do not regain compliance with the Minimum Bid Price Requirement by the end of the Compliance Period, we may be eligible for an additional 180 calendar day period to regain compliance during which we may transfer to The Nasdaq Capital Market, provided that we meet the applicable market value of publicly held shares requirement for continued listing and all other applicable requirements for initial listing thereon (except for the bid price requirement) based on our most recent public filings and market information and notify Nasdaq of our intent to cure the minimum bid price deficiency. If we meet the applicable requirements, Nasdaq may inform us that we have been granted an additional 180 calendar days to regain compliance with the Minimum Bid Price Requirement. If, however, it appears to Nasdaq that we will not be able to cure the minimum bid price deficiency, or if we are otherwise not eligible for listing on The Nasdaq Capital Market, Nasdaq could provide notice that our ADSs will become subject to delisting. In such event, Nasdaq rules would permit us to appeal the delisting determination to a Nasdaq Hearings Panel.

---

If we do not regain compliance with the MVLS Requirement by the end of the Compliance Period, Nasdaq will notify us that our securities are subject to delisting, at which point we may appeal the delisting determination to a Nasdaq hearings panel. We may also choose to transfer the listing of our ADSs to The Nasdaq Capital Market. In order to transfer, we must submit an on-line transfer application, pay a $5,000 application fee and meet The Nasdaq Capital Market’s continued listing requirements.

We intend to actively monitor our MVLS and the closing bid price of our ADS and may, if appropriate, implement available options to regain compliance with the MVLS Requirement and the Minimum Bid Price Requirement. There can be no assurance that we will be able to regain compliance with the MVLS Requirement or the Minimum Bid Price Requirement or maintain compliance with any other listing requirements.

Components of Results of Operations

Revenues

During the nine months ended March 31, 2024, we continued to deploy KidneyIntelX to patient populations with DKD, on a regional basis through partnerships with healthcare systems and insurance payors that provide coverage to those healthcare systems’ patients. If these strategic partners fail to meet their key contractual obligations or to purchase KidneyIntelX tests, that will likely have an adverse effect on us and our ability to achieve our commercial objectives, potentially including the attainment of sales volumes leading to profitability.

Cost of Revenue

During the nine months ended March 31, 2024, cost of revenue consists of costs directly attributable to the KidneyIntelX testing and services rendered, including labor, lab consumables and sample collection costs directly related to revenue generating activities.

Research and Development Expenses

Research and development costs consist primarily of costs incurred in connection with the development of KidneyIntelX. We are currently continuing to conduct clinical utility and other studies for KidneyIntelX to determine clinical value and performance in different CKD populations. We expense research and development costs as incurred. Because we have limited resources and access to capital to fund our operations, we must decide which diagnostic product to pursue and the amount of resources to allocate to each. As such, we have been focused primarily on the development of KidneyIntelX and studies to further demonstrate the clinical utility of KidneyIntelX.

We incur both direct and indirect expenses related to our research and development programs. Direct expenses include third-party expenses related to our programs such as expenses for data science and artificial intelligence capabilities, consulting fees, lab supplies, assay development services and clinical validation costs. Indirect expenses include salaries and other personnel-related costs, including share-based compensation for personnel in research and development functions and rent.

At the end of the reporting period, we compare payments made to third-party service providers to the estimated progress toward completion of the research or development objectives. Such estimates are subject to change as additional information becomes available. Depending on the timing of payments to the service providers and the progress that we estimate to have been made as a result of the service provided, we may record net prepaid or accrued expense relating to these costs. Upfront milestone payments made to third parties who perform research and development services on our behalf are expensed as services are rendered.

The successful commercialization of KidneyIntelX is uncertain. This is due to the numerous risks and uncertainties associated with product development and commercialization, including:

---

A change in the outcome of any of these variables could result in a significant change in the costs and timing associated with our related development.

General and Administrative Expenses

General and administrative expenses consist principally of salaries and other personnel-related costs including share-based compensation; professional fees for accounting, auditing, tax and administrative consulting services; legal fees relating to patent and corporate matters; administrative travel expenses; insurance costs; marketing expenses and other operating costs. Additionally, general and administrative expenses include the cost of maintaining our admission to AIM and Nasdaq.

Impairment loss on property, equipment and other long-lived assets

On a quarterly basis, the respective carrying value of non-financial assets are assessed for impairment indicators and, if ultimately considered impaired, are adjusted and written down to their fair value, as estimated based on consideration of external market participant assumptions.

Foreign Currency Gain (Loss), net

Foreign currency gain (loss), net consists of foreign currency income (losses) due to exchange rate fluctuations on transactions denominated in a currency other than our functional currency.

Fair Value Adjustments to VericiDx Investment

In October 2020, we completed a spin off VericiDx plc. ("VericiDx"), a developer of advanced clinical diagnostics for organ transplant and retained 9,831,681 ordinary shares of VericiDx. We account for the investment in VericiDx equity securities at fair value, with changes in fair value recognized in the income statement. In March 2024, we sold 750,000 ordinary shares of VericiDx for net proceeds of $0.1 million and a realized loss of $0.1 million. As of March 31, 2024, we own 9,081,681 shares of VericiDx.

Fair Value Adjustment on Convertible Notes

We elected to account for the Bonds (as defined below) at fair value with qualifying changes in fair value recognized through the statements of operations until the notes are settled.

Other Income (Expense)

Other income relates to interest income earned on our cash deposits and grant income earned for work performed under the Horizon Europe grant.

During the nine months ended March 31, 2024, we recorded $0.2 million of other income which included $0.2 million of interest income earned on our cash deposits and $0.1 million of grant income, offset by $0.1 million of realized loss on the sale of VericiDx shares. During the nine months ended March 31, 2023, we recognized $0.5 million of other income which included $0.4 million of other income related to Kantaro and expense reimbursement and $0.1 million of interest income.

Liquidity and Capital Resources

Since our inception, we have incurred net losses. We incurred net losses of $26.4 million and $34.5 million for the nine months ended March 31, 2024 and 2023, respectively. As of March 31, 2024, we had an accumulated deficit of $204.7 million.

On March 12, 2024, we entered into a Placing Agreement (the “Placing Agreement”) with Stifel Nicolaus Europe Limited (the “Bookrunner” or “Stifel”), pursuant to which we agreed to allot and issue new ordinary shares, nominal value £0.0025 per ordinary share (the “Placing Shares”) to certain investors (the “Placees”) in an unregistered offering (the “Private Placement”), up to an aggregate of 46,801,872 ordinary shares, in two tranches.We allotted and issued 19,986,031 Placing Shares at a placing price of £0.20 per Placing Share (the “First Tranche”), which closed on March 14, 2024. Subsequent to obtaining the required shareholder approval, we allotted and issued 26,815,841 Placing Shares at a placing price of £0.20 per Placing Share (the “Second Tranche”), which closed on April 24, 2024. We received aggregate gross proceeds of approximately $12 million from the closing of the First Tranche and Second Tranche, before deducting fees and commissions to the Bookrunner and other offering expenses payable by us.

On April 5, 2024, we entered into a securities purchase agreement (the “DB Capital Purchase Agreement”) with an institutional investor pursuant to which we agreed to issue and sell, in a registered direct offering (the “Registered Direct Offering”) 2,666,667 ordinary shares, nominal value £0.0025 per share. Pursuant to the DB Capital Purchase Agreement, we also granted the investor an option to purchase up to 7,811,696 additional ordinary shares at the offering price of $0.375 per share. The purchase price of each

---

ordinary share is $0.375. On April 18, 2024, the investor partially exercised the option to purchase 1,333,334 ordinary shares. The gross proceeds to the Company from the Registered Direct Offering were approximately $1.5 million, before deducting offering expenses payable by the Company. The Shares were offered by the Company pursuant to an effective shelf registration statement on Form S-3 (File No. 333-274733) that was filed with the SEC on September 28, 2023 and became effective on October 6, 2023, including the base prospectus contained therein, and a related prospectus supplement dated as of April 5, 2024 filed with the SEC.

We expect to incur additional losses in the near future, and we expect our expenses to increase substantially in connection with our ongoing activities, particularly as we continue to commercialize and scale KidneyIntelX, as we conduct our ongoing and planned clinical utility and other studies for KidneyIntelX for its commercial launch, develop and refine our artificial intelligence technology platform, seek and maintain regulatory clearances or approvals for KidneyIntelX or any other product we develop, establish and maintain partnerships with healthcare systems, pursue our coverage and reimbursement strategy, and continue to invest in our infrastructure to support our manufacturing and other activities. In addition, we expect to incur additional costs associated with operating as a public company in the United States. The timing and amount of our operating expenditures will depend largely on:

To date, we have primarily financed our operations through equity and debt financings. As of March 31, 2024, we had cash and cash equivalents of $4.7 million. We have incurred recurring losses and negative cash flows from operations since inception and had an accumulated deficit of $204.7 million as of March 31, 2024. We anticipate incurring additional losses until such time, if ever, that we can generate significant sales of KidneyIntelX or any future products currently in development. As a result of our losses and our projected cash needs, substantial doubt exists about our ability to continue as a going concern within 12 months after the date that the financial statements are issued.

Substantial additional capital will be necessary to fund our operations, expand our commercial activities and develop other potential diagnostic related products. We plan to finance our cash needs through a combination of revenue from sales, securities offerings, debt financings, collaborations, strategic alliances and marketing, distribution or licensing arrangements with third parties. To the extent that we raise additional capital through the sale of equity or convertible debt securities, the ownership interest of our shareholders will be diluted, and the terms of these securities may include liquidation or other preferences that adversely affect the rights of our shareholders.

Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making capital expenditures or declaring dividends. If we raise funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue streams, research programs or diagnostic products or grant licenses on terms that may not be favorable to us. Additional capital may not be available when needed, on reasonable terms, or at all, and our ability to raise additional capital may be adversely impacted by potential worsening global economic conditions and disruptions to and volatility in the credit and financial markets in the United States and worldwide. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed, we may not be able to meet our obligations and we may be required to delay, curtail or discontinue our product development or future commercialization efforts, or grant rights to develop and market products that we would otherwise prefer to develop and market ourselves.

---

Going Concern

We have limited sources of revenue to provide incoming cash flows to sustain our future operations. As outlined above, our ability to pursue our planned business activities is dependent upon our successful efforts to raise additional capital and the effectiveness of our cost-cutting and other capital preservation measures. Without additional financing, we expect our cash and cash equivalents as of March 31, 2024, combined with additional cost reduction options available, will be sufficient to fund our operating expenses and capital expenditure requirements into early fiscal fourth quarter. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect or may fail in our efforts to enact additional cost reduction options. Furthermore, our operating plan may change, and we may need additional funds sooner than planned in order to meet operational needs and capital requirements for product development and commercialization.

These factors raise substantial doubt regarding our ability to continue as a going concern. Our condensed consolidated financial statements have been prepared on a going concern basis, which implies that we will continue to realize our assets and discharge our liabilities in the normal course of business. Our financial statements do not include any adjustments to the recoverability and classification of recorded asset amounts and classification of liabilities that might be necessary should we be unable to continue as a going concern.

Cash Flows

The following table shows a summary of our cash flows from operations for the periods indicated (in thousands):

		For the Nine Months Ended March 31,											Change 2024 vs. 2023
(in thousands, except share and per share amounts)		2024						2023					Change				%
Net cash used in operating activities		$		(22,285	)			$		(25,452	)			3,167				-12	%

Net cash used in operating activities

During the nine months ended March 31, 2024, net cash used in operating activities was $22.3 million and was primarily attributable to our $26.4 million net loss as well as $4.8 million of noncash charges and $0.7 million net change in our operating assets and liabilities. Noncash charges were primarily related to $2.3 million fair value adjustment related to the Bonds, $1.3 million in share-based compensation expense, $0.7 million of loss on write off of assets, $0.3 million of depreciation and amortization expense, and $0.2 million fair value adjustment on our VericiDx investment. The change in our operating assets and liabilities was primarily attributable to a $1.1 million decrease in accrued expenses and other current liabilities, offset by a $0.4 million increase in accounts receivables, prepaids and other current assets.

During the nine months ended March 31, 2023, net cash used in operating activities was $25.5 million and was primarily attributable to our $34.5 million net loss including a $3.0 million net change in our operating assets and liabilities and $6.1 million in noncash charges. The change in our operating assets and liabilities was primarily attributable to a $2.9 million increase in accounts payable and accrued expenses and other current liabilities and a $0.1 million increase in accounts receivable, prepaid expenses and other current assets. Noncash charges were primarily related to $2.4 million in share-based compensation, $1.1 million fair value adjustment of our VericiDx securities, $1.9 million fair value adjustment of our convertible debt, a $0.3 million unrealized foreign exchange loss, $0.3 million of depreciation and amortization and $0.1 million of non-cash lease expense.

Net cash used in investing activities

During the nine months ended March 31, 2024, net cash used investing activities was immaterial.

During the nine months ended March 31, 2023, net cash used in investing activities was $0.1 million, attributable to the payment of long term deferred expenses.

---

Net cash provided by financing activities

During the nine months ended March 31, 2024, net cash provided by financing activities was $2.5 million and was primarily attributable to $5.1 million in proceeds from the closing of the First Tranche of the Private Placement, $0.1 million in proceeds from the issuance of ordinary shares under our employee stock purchase program, offset by $1.7 million in cash used to pay down the principal of the Bonds and $1.0 million in cash paid for offering costs related to the issuance of ordinary shares.

During the nine months ended March 31, 2023, net cash from financing activities was $16.5 million and was primarily attributable to $20.3 million in gross proceeds from the issuance of ordinary shares and $0.1 million in proceeds from the issuance of ordinary shares under our employee stock purchase program offset by $3.2 million in cash used to pay down the principal and interest of the convertible debt and $0.7 million in cash paid for offering costs related to the issuance of ordinary shares.

Recent Accounting Pronouncements

See Note 3 to our financial statements found elsewhere in this report for a description of recent accounting pronouncements applicable to our financial statements.

JOBS Act Transition Period

In April 2012, the JOBS Act was enacted. Section 107 of the JOBS Act provides that an “emerging growth company” can take advantage of the extended transition period provided in Section 7(a)(2)(B) of the Securities Act of 1933, as amended, for complying with new or revised accounting standards. An emerging growth company can delay the adoption of certain accounting standards until those standards would otherwise apply to private companies. We have elected to take advantage of the extended transition period for complying with new or revised accounting standards and, as a result, our financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

We have evaluated the benefits of relying on other exemptions and reduced reporting requirements under the JOBS Act. Subject to certain conditions, as an emerging growth company, we have chosen to rely on certain of these exemptions, including without limitation exemptions to the requirements for (1) providing an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404(b) of the Sarbanes-Oxley Act and (2) complying with any requirement that may be adopted by the Public Company Accounting Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements, known as the auditor discussion and analysis. We will remain an emerging growth company until the earlier to occur of (a) June 30, 2026, (b) the last day of the fiscal year (1) in which we have total annual gross revenues of at least $1.235 billion or (2) in which we are deemed to be a “large accelerated filer” under the rules of the SEC, which means the market value of our ordinary shares and ADSs that are held by non-affiliates exceeds $700.0 million as of the prior December 31, or (c) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

Critical Accounting Estimates

Our management’s discussion and analysis of our financial condition and results of operations are based on our financial statements, which have been prepared in accordance with U.S. generally accepted accounting principles. The preparation of these financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, and expenses and the disclosure of contingent assets and liabilities in our financial statements. On an ongoing basis, we evaluate our estimates and judgments, including those related to accrued expenses and share-based compensation. We base our estimates on historical experience, known trends and events, and various other factors that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

While our significant accounting policies are described in more detail in Note 3 to our financial statements included elsewhere in this report, we believe the following accounting policies are the most critical to the judgments and estimates used in the preparation of our financial statements.

---

Research and Development Expenses

Research and development expenses consist primarily of costs incurred in connection with the development of KidneyIntelX. We expense research and development costs as incurred.

At the end of the reporting period, we compare payments made to third-party service providers to the estimated progress toward completion of the research or development objectives. Such estimates are subject to change as additional information becomes available. Depending on the timing of payments to the service providers and the progress that we estimate has been made as a result of the service provided, we may record a prepaid expense or accrued liability relating to these costs. Upfront milestone payments made to third parties who perform research and development services on our behalf are expensed as services are rendered. Contingent development or regulatory milestone payments are recognized upon the related resolution of such contingencies.

We make estimates of our accrued expenses as of each balance sheet date in our financial statements based on facts and circumstances known at that time. If the actual timing of the performance of services or the level of effort varies from the estimate, we will adjust the accrual accordingly. Nonrefundable advance payments for goods and services, including fees for process development or manufacturing and distribution of clinical supplies that will be used in future research and development activities, are deferred and recognized as expense in the period that the related goods are consumed or services are performed.

Share-based Compensation

We measure equity classified share-based awards granted to employees and nonemployees based on the estimated fair value on the date of grant and recognize compensation expense of those awards over the requisite service period, which is the vesting period of the respective award. We account for forfeitures as they occur. For share-based awards with service-based vesting conditions, we recognize compensation expense on a straight-line basis over the service period. The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model, which requires inputs based on certain subjective assumptions, including the expected stock price volatility, the expected term of the option, the risk-free interest rate for a period that approximates the expected term of the option, and our expected dividend yield. We were a privately-held organization prior to November 2018 and have been a publicly-traded company for a limited period of time and therefore lack company-specific historical and implied volatility information for our shares. Therefore, we estimate our expected share price volatility based on the historical volatility of publicly-traded peer companies and expect to continue to do so until such time as we have adequate historical data regarding the volatility of our own traded share price. The expected term of our stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is none based on the fact that we have never paid cash dividends on ordinary shares and do not expect to pay any cash dividends in the foreseeable future.

We classify share-based compensation expense in our consolidated statement of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.

Convertible Notes

In April 2022, we issued amortizing senior convertible bonds with a principal amount of $21.2 million in amortizing senior convertible bonds due in April 2027 (the “Bonds”) to CVI Investments, Inc. (the “Convertible Bond Investor”). The Bonds were issued at 85% par value with total net proceeds of $18.0 million and accrue interest at an annual rate of 5.5%, payable quarterly in arrears, in cash or ADSs valued at the ADS Settlement Price at our option. The principal and interest payments are due in equal quarterly installments starting in July 2022. The Bonds contain various conversion and redemption features. The initial conversion price for the Convertible Bonds of $8.70 has been set at a 20 percent premium to the Reference ADS Price. The Conversion Price may reset down at 12, 24 and 36 months, depending on share price performance, the Bonds have a hard floor in the conversion price of $7.25. As a result of the February 2023 private placement and pursuant to conditions of the bond agreement, the conversion price was adjusted to $8.2508 (previously $8.70) and the floor price was adjusted to $6.8757 (previously $7.25). Further, pursuant to conditions of the agreement, effective April 7, 2023, the conversion price was adjusted from $8.2508 to $7.7924. Between amortization dates, Heights Convertible Bond Investor retains the right to advance future amortization payments, provided that (a) there shall be no amortization advancements during the first 12 months, (b) no more than 2 amortization advancements may occur in any 12 month period, and (c) no more than 1 amortization advancement may occur in any 3 month period. On March 28, 2024, the Company entered into a second amendment and restatement agreement with the Convertible Bond Investor, which amended the terms of the Company’s existing bond agreement, dated March 31, 2022. The Company performed an analysis and determined that the financial impact was immaterial as the amended and restated agreement was not substantially different than the previous agreement.

---

The Convertible Bond Investor is also permitted to defer up to two amortization payments to a subsequent amortization date. We retain the option to repay any deferred amortization in cash at 100 percent of the nominal amount. In July 2022, we made a cash amortization payment of $1.4 million, which consisted of $1.1 million of principal and $0.3 million of interest. In October 2022, the Convertible Bond Investor deferred the October amortization payment to maturity of the bond and we made an interest payment of $0.3 million. In January 2023, we made a cash amortization payment of $1.4 million, which consisted of $1.1 million of principal and $0.3 million of interest. In April 2023, we made a cash amortization payment of $1.4 million, which consisted of $1.1 million of principal and $0.3 million of interest. In October 2023, we made an amortization payment of $1.3 million, which consisted of $1.1 million of principal and $0.2 million of interest, through the issuance of 2,335,388 ordinary shares in the form of 150,000 Ordinary Shares and 1,092,694 ADSs. In December 2023, we made an amortization payment of $1.3 million, which consisted of $1.1 million of principal and $0.2 million of interest, through the issuance of 2,500,000 ordinary shares and a cash payment of $0.6 million. As of March 31, 2024, $13.8 million of principal was outstanding. On April 11, 2024, we issued 3,636,162 Ordinary Shares in the form of 1,818,081 ADSs to the Convertible Bond Investor (the “April Repayment”), which settled the principal and interest amount due under the bonds on April 7, 2024. After settlement of the Repayment, the principal remaining under the Bonds was reduced by $1.06 million to $12.72 million. The Shares were issued without registration in reliance upon the exemption provided in Section 3(a)(9) of the Securities Act.

We elected the fair value option to account for the Bonds as we believe the fair value option provides users of the financial statements with greater ability to estimate the outcome of future events as facts and circumstances change, particularly with respect to changes in the fair value of the ordinary shares underlying the conversion option. The fair value of the Bonds is determined using a scenario-based analysis that estimates the fair value based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes available to the noteholders. For each reporting period, changes in the fair value of the Bonds are recognized through other income (expense) with the portion of the change that results from a change in the instrument-specific credit risk recorded separately in Other Comprehensive Income for each reporting period.

Item 3. Quantitative and Qualitative Disclosures About Market Risk.

We are a smaller reporting company and not required to provide this information.

Item 4. Controls and Procedures.

Evaluation of Disclosure Controls and Procedures

We maintain “disclosure controls and procedures,” as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, that are designed to ensure that information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the rules and forms of the Securities and Exchange Commission. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is accumulated and communicated to management, including our chief executive officer (principal executive officer) and chief financial officer (principal financial officer), as appropriate, to allow timely decisions regarding required disclosure.

Our principal executive officer and principal financial officer, after evaluating the effectiveness of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) of the Exchange Act) as of March 31, 2024, have concluded that, as of such date, our disclosure controls and procedures were effective as described further below.

It should be noted that any system of controls is based in part upon certain assumptions designed to obtain reasonable (and not absolute) assurance as to its effectiveness, and there can be no assurance that any design will succeed in achieving its stated goals.

Management does not expect that our internal control over financial reporting will prevent or detect all errors and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control systems are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in a cost-effective control system, no evaluation of internal control over financial reporting can provide absolute assurance that misstatements due to error or fraud will not occur or that all control issues and instances of fraud, if any, have been or will be detected.

Changes in Internal Control Over Financial Reporting

There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) that occurred during the fiscal quarter ended March 31, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

PART II

Item 1. Legal Proceedings.

From time to time, we may become involved in legal proceedings arising in the ordinary course of our business. We are not currently subject to any material legal proceedings.

Item 1A. Risk Factors.

In addition to the other information set forth in this Quarterly Report, you should carefully consider the risk factors and other cautionary statements described under the heading “Item 1A. Risk Factors” included in our 2023 Annual Report on Form 10-K and the risk factors and other cautionary statements contained in our other SEC filings, which could materially affect our business, financial condition or future results. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition or future results.

Our review of potential strategic alternatives may not result in the approval or completion of any specific transaction or outcome, and the process of reviewing strategic alternatives or the outcome could adversely affect our business, financial condition, operations and stock price.

On March 4, 2024, we announced that we had received an unsolicited approach from a large and well-capitalized publicly listed strategic diagnostics company, which is in the process of evaluating an acquisition of the entire issued, and to be issued, share capital of the Company. Therefore, we have commenced a review of all available options, including a possible sale of the Company and/or our assets, and have commenced the Formal Sale Process. We have not yet established a timeline for completion of the strategic review process, and there is no assurance that the process will result in the approval or completion of any specific transaction or outcome. We are actively working with financial and legal advisors in connection with our review of potential strategic alternatives.

Any potential transaction or other strategic alternative would be dependent on a number of factors that may be beyond our control, including, among other things, market conditions, industry trends, regulatory approvals, and the availability of financing for a potential transaction on reasonable terms. The process of reviewing potential strategic alternatives, including optimization of our cost structure, is time consuming, may divert the attention of our board of directors and management from core business operations, and may be distracting and disruptive to our business operations and long-term planning, which may cause concern to our current or potential employees, investors, strategic partners and other stakeholders, and may have a material impact on our business and operating results or our internal controls and procedures, or result in increased volatility in our share price. We may incur substantial expenses associated with identifying, evaluating and negotiating potential strategic alternatives. There can be no assurance that any potential transaction or other strategic alternative, if consummated, will provide greater value to our shareholders than that reflected in the current price of our ADSs or ordinary shares. Additionally, the outcome of the strategic review may adversely impact our business, cash flows, operations, financial condition and stock price. Until the review process is concluded or developments on the progress of the strategic review are disclosed, perceived uncertainties related to our future may result in the loss of potential business opportunities, volatility in the market price of our ADSs or ordinary shares, and difficulty attracting and retaining qualified employees and business partners.

Protections found in provisions under the United Kingdom City Code on Takeovers and Mergers may delay or discourage a takeover attempt, including attempts that may be beneficial to holders of our Ordinary Shares and ADSs.

The United Kingdom City Code on Takeovers and Mergers, or the City Code, applies, among other things, to an offer for a public limited company whose shares are admitted to trading on AIM. The Company is therefore subject to the City Code.

The City Code provides a framework within which takeovers of certain companies organized in the United Kingdom are regulated and conducted. The following is a brief summary of some of the most important rules of the City Code:

---

Our future capital needs are uncertain, and our independent registered public accounting firm has expressed in its report on our audited financial statements for the fiscal year ended June 30, 2023, a substantial doubt about our ability to continue as a going concern. Our ability to continue as a going concern is dependent on our ability to raise additional capital and our operations could be curtailed if we are unable to obtain the required additional funding when needed. We may not be able to do so when necessary, and/or the terms of any financings may not be advantageous to us.

Our financial statements included in this report have been prepared assuming we will continue to operate as a going concern. However, due to our recurring losses from operations, and working capital deficiency, there is substantial doubt about our ability to continue as a going concern. Because we expect to continue to experience negative cash flow, our ability to continue as a going concern is subject to our ability to obtain necessary funding from outside sources, including obtaining additional funding from offerings of our equity securities or debt, transactions involving product development, licensing or collaboration, or other forms of financing. Management intends to continue its efforts to contain costs and to raise additional capital until we can generate sufficient cash from commercial sales to support operations, if ever. If we are unable to obtain sufficient financing, we may be required to delay, scale back or discontinue one or more product development programs, curtail our commercialization activities and significantly reduce expenses or we may not be able to continue as a going concern. As a result, our independent registered public accounting firm has expressed in its auditors’ report on the financial statements included in our Annual Report on Form 10-K a substantial doubt regarding our ability to continue as a going concern. Our financial statements in our Annual Report on Form 10-K and in this report do not include any adjustments that might result from the outcome of the uncertainty regarding our ability to continue as a going concern. If we cannot continue as a going concern, we may have to liquidate our assets and may receive less than the value at which those assets are carried on our financial statements, and our shareholders may lose their entire investment in our securities. Further, the perception that we may be unable to continue as a going concern may impede our ability to pursue strategic opportunities or operate our business due to concerns regarding our ability to discharge our contractual obligations. Future reports from our independent registered public accounting firm may also contain statements expressing doubt about our ability to continue as a going concern.

---

Without additional financing, we expect our cash and cash equivalents as of March 31, 2024, combined with additional cost reduction options available, will be sufficient to fund our operating expenses and capital expenditure requirements into early fiscal fourth quarter. We have based this estimate on assumptions that may prove to be wrong, and we could utilize our available capital resources sooner than we currently expect or may fail in our efforts to enact additional cost reduction options. Furthermore, our operating plan may change, and we may need additional funds sooner than planned in order to meet operational needs and capital requirements for product development and commercialization.

If we fail to meet all applicable requirements of Nasdaq and Nasdaq determines to delist our ADSs, the delisting could adversely affect the market liquidity of our ADSs and the market price of our ADSs could decrease.

On December 22, 2023, we received two written notices from Nasdaq Stock Market, notifying us that (i) because the closing bid price for our ADSs was below $1.00 per ADS for at least 30 consecutive business days, we did not meet the $1.00 per ADS Minimum Bid Price Requirement and (ii) we are not in compliance with the requirement to maintain a minimum MVLS of $50,000,000 for continued listing on The Nasdaq Global Market, as set forth in Nasdaq Listing Rule 5450(b)(2)(A).

The Notices have no immediate impact on the continued listing or trading of our ADSs on The Nasdaq Global Market, which will continue to be listed and traded on The Nasdaq Global Market, subject to our compliance with the other continued listing requirements.

Pursuant to Nasdaq Listing Rule 5810(c)(3)(A) and Nasdaq Listing Rule 5810(c)(3)(C), we have a compliance period of 180 calendar days, or until June 19, 2024, to regain compliance with the Minimum Bid Price Requirement and the MVLS Requirement. To regain compliance with the Minimum Bid Price Requirement, the closing bid price of the ADSs must be at least $1.00 per ADS for a minimum of ten consecutive business days prior to the end of the Compliance Period. To regain compliance with the MVLS Requirement, our MVLS must close at $50,000,000 or more for a minimum of ten consecutive business days prior to the end of the Compliance Period.

If we do not regain compliance with the Minimum Bid Price Requirement by the end of the Compliance Period, we may be eligible for an additional 180 calendar day period to regain compliance during which we may transfer to The Nasdaq Capital Market, provided that we meet the applicable market value of publicly held shares requirement for continued listing and all other applicable requirements for initial listing thereon (except for the bid price requirement) based on our most recent public filings and market information and notify Nasdaq of our intent to cure the minimum bid price deficiency. If we meet the applicable requirements, Nasdaq may inform us that we have been granted an additional 180 calendar days to regain compliance with the Minimum Bid Price Requirement. If, however, it appears to Nasdaq that we will not be able to cure the minimum bid price deficiency, or if we are otherwise not eligible for listing on The Nasdaq Capital Market, Nasdaq could provide notice that our ADSs will become subject to delisting. In such event, Nasdaq rules would permit us to appeal the delisting determination to a Nasdaq Hearings Panel.

If we are unable to satisfy the Nasdaq criteria for continued listing, our ADS would be subject to delisting. A delisting of our ADS could negatively impact us by, among other things, reducing the liquidity and market price of our ADS; reducing the number of investors willing to hold or acquire our ADS, which could negatively impact our ability to raise equity financing; decreasing the amount of news and analyst coverage of us; and limiting our ability to issue additional securities or obtain additional financing in the future. In addition, delisting from Nasdaq may negatively impact our reputation and, consequently, our business.

We may be required to register with the SEC as an “investment company” in accordance with the Investment Company Act of 1940.

The rules and interpretations of the SEC and the courts, relating to the definition of "investment company" are very complex. While we currently intend to conduct our operations so that we will not be an investment company under applicable SEC interpretations, we can provide no assurance that the SEC would not take the position that the Company would be required to register under the Investment Company Act of 1940 (the “‘40 Act”) and comply with the ‘40 Act’s registration and reporting requirements, capital structure requirements, affiliate transaction restrictions, conflict of interest rules, requirements for disinterested directors, and other substantive provisions. We monitor our assets and income for compliance under the ‘40 Act and seek to conduct our business activities to ensure that we do not fall within its definitions of “investment company” or that we qualify under one of the exemptions or exclusions provided by the ‘40 Act and corresponding SEC regulations. If we were to become an “investment company” and be subject to the restrictions of the ‘40 Act, those restrictions likely would require significant changes in the way we do business and add significant administrative costs and burdens to our operations. To ensure we do not fall within the ‘40 Act, we may need to take various actions which we might otherwise not pursue. These actions may include modifying our mixture of assets and income or a liquidation of certain of our assets.

Business and risks	1. Business and risks Renalytix PLC and its wholly-owned subsidiaries, (the “Company” or "Renalytix") is an artificial intelligence-enabled in vitro diagnostics company, focused on optimizing clinical management of kidney disease to drive improved patient outcomes and significantly lower healthcare costs. KidneyIntelX, the Company’s first-in-class diagnostic platform, employs a proprietary artificial intelligence-enabled algorithm that combines diverse data inputs, including validated blood-based biomarkers, inherited genetics and personalized patient data from EHR systems, to generate a unique patient risk score. Additionally, the Company plans to pursue collaborations with pharmaceutical companies and make ‘Pharmaceutical Services Revenue’ a core part of the business going forward with the goal of improving guideline-based standard-of-care for optimal utilization of existing and novel therapeutics using the KidneyIntelX testing platform and proprietary care management software. Since inception in March 2018, the Company has focused primarily on organizing and staffing the Company, raising capital, developing the KidneyIntelX platform, conducting clinical validation studies for KidneyIntelX, establishing and protecting its intellectual property portfolio and commercial laboratory operations, pursuing regulatory clearance and developing a reimbursement strategy. The Company has funded its operations primarily through equity and debt financings. The Company is subject to risks and uncertainties common to early-stage companies in the diagnostics industry, including, but not limited to, ability to secure additional capital to fund operations, compliance with governmental regulations, development by competitors of new technological innovations, dependence on key personnel and protection of proprietary technology. To achieve widespread usage, KidneyIntelX and additional diagnostic products currently under development will require extensive clinical testing and validation prior to regulatory approval and commercialization. These efforts require significant amounts of additional capital, adequate personnel, and infrastructure, and extensive compliance-reporting capabilities.

Liquidity and Going Concern	9 Months Ended

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Liquidity and Going Concern	2. Liquidity and Going Concern The Company has incurred recurring losses and negative cash flows from operations since inception and had an accumulated deficit of $204.7 million as of March 31, 2024. The Company anticipates incurring additional losses until such time, if ever, that it can generate significant sales of KidneyIntelX or any future products currently in development. As a result of its losses and projected cash needs, substantial doubt exists about the Company’s ability to continue as a going concern. Substantial additional capital will be necessary to fund the Company's operations, expand its commercial activities and develop other potential diagnostic related products. The Company is seeking additional funding through public or private equity offerings, debt financings, other collaborations, strategic alliances and licensing arrangements. The Company may not be able to obtain financing on acceptable terms, or at all, and the Company may not be able to enter into strategic alliances or other arrangements on favorable terms, or at all. The terms of any financing may adversely affect the holdings or the rights of the Company’s shareholders. If the Company is unable to obtain funding, the Company may not be able to meet its obligations and could be required to delay, curtail or discontinue research and development programs, product portfolio expansion or commercialization efforts, which could adversely affect its business prospects. The Company’s ability to continue as a going concern is contingent upon successful execution of management’s intended plan over the next twelve months to improve the Company’s liquidity and profitability, which includes, without limitation: • Seeking additional capital through public or private equity offerings, debt financings, other collaborations, strategic alliances and licensing arrangements • Implementation of various additional operating cost reduction options that are available to the Company • The achievement of a certain volume of assumed revenue The consolidated financial statements do not include any adjustments that may result from the outcome of this going concern uncertainty.

Any reference in these notes to applicable guidance is meant to refer to U.S. GAAP as found in the Accounting Standards Codification (“ASC”) and Accounting Standards Updates (“ASU”) of the Financial Accounting Standards Board (“FASB”). In the opinion of management, the unaudited condensed consolidated financial statements reflect all adjustments, which include only normal recurring adjustments necessary for the fair statement of the balances and results for the periods presented. Principles of consolidation The consolidated financial statements include the accounts of Renalytix plc, and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation. The Company accounts for investments in which it has significant influence but not a controlling financial interest using the equity method of accounting. Use of estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Due to the uncertainty of factors surrounding the estimates or judgments used in the preparation of the consolidated financial statements, actual results may materially vary from these estimates. Estimates and assumptions are periodically reviewed, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Significant areas that require management’s estimate include the assumptions used in determining the fair value of share-based awards, determining the fair value of the bonds, recording the prepaid/accrual and associated expense for research and development activities performed for the Company by third parties and determining useful lives of property and equipment and capitalized software. Segment information The Company manages its operations as a single operating segment for the purposes of assessing performance and making operating decisions. The Company’s singular focus is to make significant improvements in kidney disease diagnosis and prognosis, clinical care, patient stratification for drug clinical trials, and drug target discovery. Foreign currency The Company’s consolidated financial statements are presented in U.S. dollars, the reporting currency of the Company. The functional currency of Renalytix plc and Renalytix AI Limited is GB Pounds. The functional currency of Renalytix AI, Inc. is the U.S. dollar. Assets and liabilities of Renalytix plc and Renalytix AI Limited are translated at the rate of exchange at period-end, while the statements of operations are translated at the weighted average exchange rates in effect during the reporting period. The net effect of these translation adjustments is shown as a component of accumulated other comprehensive loss. Transaction gains and losses resulting from exchange rate changes on transactions denominated in currencies other than the functional currency are included in income in the period in which the change occurs and reported in the consolidated statements of operations and comprehensive loss. Concentrations of credit risk and major customers Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable balances. Periodically, the Company maintains deposits in accredited financial institutions in excess of federally insured limits. The Company deposits its cash in financial institutions that it believes have high credit quality and are not exposed to any unusual credit risk beyond the normal credit risk associated with commercial banking relationships and has not experienced any losses on such accounts. The Company’s accounts receivables are derived from revenue earned from customers located in the U.S. For the nine months ended March 31, 2024, approximately 47% of all receivables related to KidneyIntelX testing revenue related to two customers and the remaining 53% of receivables were due from other third party payors. For the nine months ended March 31, 2023, approximately 73% of all receivables related to Mount Sinai, approximately 15% of all receivables related to Medicare claims and the remaining 12% of receivables were due from other third party payors. The Company performs initial and ongoing credit reviews on customers, which involve consideration of the customers’ financial information, their location, and other factors to assess the customers’ ability to pay and reserved for $0.1 million of receivables as of March 31, 2024. Fair value of financial instruments At March 31, 2024 and June 30, 2023, the Company’s financial instruments included accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other current liabilities. The carrying amounts of these assets and liabilities approximates fair value due to their short-term nature. The convertible notes are recorded at their estimated fair value. Fair value option Under the Fair Value Option Subsections of ASC subtopic 825-10, Financial Instruments – Overall, the Company has the irrevocable option to report most financial assets and financial liabilities at fair value on an instrument-by-instrument basis, with changes in fair value reported in earnings (see Note 5). The Company has elected to measure and record the convertible notes at their estimated fair value. Cash and cash equivalents The Company considers all highly liquid investments purchased with an original maturity of 90 days or less to be cash equivalents. As of March 31, 2024 and June 30, 2023, the Company had cash and cash equivalents of $4.7 million and $24.7 million, respectively. Accounts receivable Accounts receivable are recorded at the invoice amount and are non-interest bearing. The Company estimates expected credit losses of its accounts receivable by assessing the risk of loss and available relevant information about collectability, including historical credit losses, existing contractual payment terms, actual payment patterns of its customers, individual customer circumstances, and reasonable and supportable forecast of economic conditions expected to exist throughout the contractual life of the receivable. The Company reserved for $0.1 million of receivables as of March 31, 2024. The Company reserved for $0.1 million of receivables as of June 30, 2023. Property, equipment and other long-lived assets Property and equipment are recorded at cost. Depreciation is determined using the straight-line method over the estimated useful lives ranging from three to ten years. Expenditures for maintenance and repairs are expensed as incurred while renewals and betterments are capitalized. When property and equipment are sold or otherwise disposed of, the cost and related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in operations. In November 2023, the Company consolidated lab operations which resulted in a $0.3 million impairment of property and equipment at the Company's Utah lab. In February 2024, the Company performed a recoverability assessment and determined the entire $0.1 million right-of-use asset related to the Utah lease to be impaired, and in addition the Company further consolidated lab operations which resulted in a $0.3 million impairment of property and equipment at the Company's Florida lab. The Company recorded a $0.4 million impairment of property, equipment and other long-lived assets for the three months ended March 31, 2024 and a $0.7 million impairment for the nine months ended March 31, 2024. There was no impairment loss on property, equipment and other long-lived assets in the nine months ended March 31, 2023. Investments VericiDx plc The Company accounts for its ownership of VericiDx securities at fair value in accordance with ASC 321, Investments-Equity Securities, with changes in fair value recorded in earnings as the fair value of VericiDx's ordinary shares is readily determinable via the London Stock Exchange. Based on the closing stock price of VericiDx, the fair value of the investment in VericiDx was $1.1 million and $1.5 million at March 31, 2024 and June 30, 2023, respectively. In March 2024, the Company sold 750,000 ordinary shares of VericiDx for net proceeds of $0.1 million and a realized loss of $0.1 million. The Company did not sell any shares during the three and nine months ended March 31, 2023. During the three months ended March 31, 2024 and 2023, the Company recorded an increase in fair value of $0.04 million and $0.1 million, respectively, in the consolidated statements of operations and comprehensive loss. During the nine months ended March 31, 2024 and 2023, the Company recorded a decrease in fair value of $0.2 million and $1.1 million, respectively, in the consolidated statements of operations and comprehensive loss. The Company owned 3.7% of the ordinary shares of VericiDx at March 31, 2024, and owned 5.8% of ordinary shares of VericiDx at June 30, 2023. Impairment assessment The Company evaluates its investments that are in unrealized loss positions, if any, and equity method investments for other-than-temporary impairment on a quarterly basis (see Note 5). Such evaluation involves a variety of considerations, including assessments of the risks and uncertainties associated with general economic conditions and distinct conditions affecting specific issuers or investees. Factors considered by the Company include (i) the length of time and the extent to which an investment’s fair value has been below its cost; (ii) the financial condition, credit worthiness, and near-term prospects of the issuer; (iii) the length of time to maturity; (iv) future economic conditions and market forecasts; (v) the Company’s intent and ability to retain its investment for a period of time sufficient to allow for recovery of market value; (vi) an assessment of whether it is more likely than not that the Company will be required to sell its investment before recovery of market value; and (vii) whether events or changes in circumstances indicate that the investment’s carrying amount might not be recoverable. Software development costs The Company follows the provisions of ASC 985, Software, which requires software development costs for software marketed externally to be expensed as incurred until the establishment of technological feasibility, at which time those costs are capitalized until the software is available for general release and amortized over its estimated useful life of ten years. For the three and nine months ended March 31, 2024 and 2023, there was no capitalization of research and development expenses related to software development to record. Technological feasibility is established upon the completion of a working model that has been validated. Revenue recognition Pursuant to ASC 606, Revenue from Contracts with Customers, the Company recognizes revenue when a customer obtains control of promised goods or services. The Company records the amount of revenue that reflects the consideration that it expects to receive in exchange for those goods or services. The Company applies the following five-step model in order to determine this amount: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company only applies the five-step model to contracts when it is probable that it will collect the consideration to which it is entitled in exchange for the goods or services that it transfers to the customer. Once a contract is determined to be within the scope of ASC 606 at contract inception, the Company reviews the contract to determine which performance obligations it must deliver and which of these performance obligations are distinct. Certain contracts have options for the customer to acquire additional services. The Company evaluates these options to determine if a material right exists. If, after that evaluation, it determines a material right does exist, it assigns value to the material right based upon the renewal option approach. The Company recognizes as revenue the amount of the transaction price that is allocated to each performance obligation when that performance obligation is satisfied or as it is satisfied. The Company uses the present right to payment principle and customer acceptance as indicators to determine the transfer of control to the customer occurs at a point in time. Sales tax and other similar taxes are excluded from revenues. Cost of revenue Cost of revenue consists of costs directly attributable to the services rendered, including labor, rent, lab consumables, depreciation, amortization and sample collection costs directly related to revenue generating activities. Research and development expenses Research and development costs consist primarily of internal and external labor costs incurred in connection with the development of KidneyIntelX as well as expenses related to studies and clinical trials to further the clinical value, performance and utility of KidneyIntelX. Research and development costs are expensed as incurred. Share-based compensation The Company measures equity classified share-based awards granted to employees and nonemployees based on the estimated fair value on the date of grant and recognizes compensation expense of those awards over the requisite service period, which is the vesting period of the respective award. The Company accounts for forfeitures as they occur. For share-based awards with service-based vesting conditions, the Company recognizes compensation expense on a straight-line basis over the service period. The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model, which requires inputs based on certain subjective assumptions, including the expected stock price volatility, the expected term of the option, the risk-free interest rate for a period that approximates the expected term of the option, and the Company’s expected dividend yield. The Company was a privately-held organization prior to November 2018 and has been a publicly-traded company for a limited period of time and therefore lacks company-specific historical and implied volatility information for its shares. Therefore, it estimates its expected share price volatility based on the historical volatility of publicly-traded peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded share price. The expected term of the Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is none based on the fact that the Company has never paid cash dividends on ordinary shares and does not expect to pay any cash dividends in the foreseeable future. The Company classifies share-based compensation expense in its consolidated statement of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified. Income taxes Income taxes are accounted for under the asset and liability method as required by FASB ASC Topic 740, Income Taxes (ASC 740). Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A reduction in the carrying value of the deferred tax assets is required when it is not more likely than not that such deferred tax assets are realizable. FASB ASC Subtopic 740-10, Accounting for Uncertainty of Income Taxes (ASC 740-10), defines the criterion an individual tax position must meet for any part of the benefit of the tax position to be recognized in financial statements prepared in conformity with U.S. GAAP. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not such tax position will be sustained on examination by the taxing authorities, based solely on the technical merits of the respective tax position. The tax benefits recognized in the financial statements from such a tax position should be measured based on the largest benefit having a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority. In accordance with disclosure requirements of ASC 740-10, the Company’s policy on income statement classification of interest and penalties related to income tax obligations is to include such items as part of income tax expense. The Company recorded an immaterial provision for income taxes for the three and nine months ended March 31, 2024. The Company did not record a provision for income taxes for the three and nine months ended March 31, 2023, as the Company generated losses for such periods. The Company periodically evaluates the realizability of its deferred tax assets based on all available evidence, both positive and negative. The realization of deferred tax assets is dependent on the Company’s ability to generate sufficient future taxable income during periods prior to the expiration of tax attributes to fully utilize these assets. The Company weighed both positive and negative evidence and determined that there is a continued need for a full valuation allowance on its deferred tax assets as of March 31, 2024. Should the Company determine that it would be able to realize its remaining deferred tax assets in the foreseeable future, an adjustment to its remaining deferred tax assets would cause a material increase to income in the period such determination is made. Comprehensive loss Comprehensive loss includes net loss as well as other changes in shareholders’ equity that result from transactions and economic events other than those with shareholders. For the periods presented, changes in shareholders’ equity include foreign currency translation as well as changes in fair value of the convertible note due to changes in instrument specific credit risk. The change in instrument specific credit risk was calculated as the change in the risk yield from the convertible debt issuance date to the valuation date. The instrument specific credit risk at issuance date was calibrated such that the fair value of the convertible bond was equal to the issue price as of the issuance date. The risk yield was adjusted to reflect the change in credit spreads between the issuance date and the valuation date. Net loss per ordinary share Basic net loss per ordinary share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during each period. Diluted net loss per ordinary share includes the effect, if any, from the potential exercise or conversion of securities, such as options and convertible debt which would result in the issuance of incremental ordinary shares. The dilutive effect of convertible securities is calculated using the if-converted method. Under the if-converted method, interest charges applicable to the convertible debt as well as nondiscretionary adjustments which include any expenses or charges that are determined based on the income (loss) for the period are added back to net income. The convertible debt is assumed to have been converted at the beginning of the period (or at time of issuance, if later). For the three and nine months ended March 31, 2024, under the if-converted method, the add back of nondiscretionary adjustments and inclusion of potentially converted shares would be anti-dilutive. Emerging growth company The Company is an emerging growth company as defined in the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”). Under the JOBS Act, companies have extended transition periods available for complying with new or revised accounting standards. The Company has elected to avail itself of this exemption and, therefore, while the Company is an emerging growth company it will not be subject to new or revised accounting standards at the same time that they become applicable to other public emerging growth companies that have not elected to avail themselves of this exemption. Recently issued accounting pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments, which requires measurement and recognition of expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This is different from the previous guidance as this will require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. The Company implemented ASU 2016-13 in the fiscal year beginning July 1, 2023 and evaluated the impact of ASU 2016-13 and it did not have a material impact on the consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40), Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). ASU 2020-06 eliminates two of the three models in ASC 470-20 that require issuers to separately account for embedded conversion features and eliminates some of the requirements for equity classification in ASC 815-40-25 for contracts in an entity’s own equity. The guidance also requires entities to use the if-converted method for all convertible instruments in the diluted earnings per share calculation and generally requires them to include the effect of potential share settlement for instruments that may be settled in cash or shares. It is effective for annual periods beginning after December 15, 2023, and interim periods therein. The Company evaluated the effect of ASU 2020-06 and it is not expected to have a material impact on the consolidated financial statements.

Fair Value Disclosures [Abstract]
Fair value measurements and the fair value option	5. Fair value measurements and the fair value option Assets and liabilities recorded at fair value on a recurring basis in the consolidated balance sheets are categorized based upon the level of judgment associated with the inputs used to measure their fair values. Fair value is defined as the exchange price that would be received for an asset or an exit price that would be paid to transfer a liability in the principal or most advantageous market for the asset or liability in an orderly transaction between market participants on the measurement date. Valuation techniques used to measure fair value must maximize the use of observable inputs and minimize the use of unobservable inputs. The authoritative guidance on fair value measurements establishes a three-tier fair value hierarchy for disclosure of fair value measurements as follows: • Level 1—Quoted prices (unadjusted in active markets for identical assets or liabilities) • Level 2—Inputs other than quoted prices in active markets that are observable either directly or indirectly • Level 3—Unobservable inputs in which there is little or no market data, which require the Company to develop its own assumptions This hierarchy requires the use of observable market data when available and to minimize the use of unobservable inputs when determining fair value. The following fair value hierarchy table presents information about the Company’s assets measured at fair value on a recurring basis:       Fair value measurement at       reporting date using   (in thousands)   (Level 1)     (Level 2)     (Level 3)   March 31, 2024                   Assets:                   Equity Securities   $ 1,060     $ —     $ —   Liabilities:                   Convertible notes   $ —     $ —     $ 9,341   June 30, 2023                   Assets:                   Equity Securities   $ 1,460     $ —     $ —   Liabilities:                   Convertible notes   $ —     $ —     $ 11,948     The Company accounts for its ownership of VericiDx securities at fair value in accordance with ASC 321, Investments-Equity Securities, with changes in fair value recorded in earnings as the fair value of VericiDx's ordinary shares is readily determinable via the London Stock Exchange. In March 2024, the Company sold 750,000 ordinary shares of VericiDx for net proceeds of $0.1 million and a realized loss of $0.1 million. As of March 31, 2024, the Company owned 9,081,681 shares of VericiDx. Based on closing stock price of VericiDx, the fair value of the investment in VericiDx was $1.1 million and $1.5 million at March 31, 2024 and June 30, 2023, respectively. As further described in Note 8, in April 2022 the Company issued convertible promissory notes (the “Notes”) to an investor. The fair value option, as prescribed by ASC 815, Derivatives and Hedging, was elected and applied in connection with the preparation of these consolidated financial statements. The fair value of the Notes is determined using a scenario-based analysis that estimates the fair value based on the probability-weighted present value of expected future investment returns, considering each of the possible outcomes available to the noteholders. The Company adjusts the carrying value of the Notes to their estimated fair value at each reporting date, with qualifying increases or decreases in the fair value recorded as change in fair value of convertible promissory notes in the statements of operations and comprehensive loss. Changes in the fair value resulting from changes in the instrument-specific credit risk will be presented separately in other comprehensive income. The following table shows the fair value movements of the Notes for the nine months ended March 31, 2024:   (in thousands)       Balance at July 1, 2023   $ 11,948   Change due to payment of principal and interest     (4,911 ) Fair value adjustments     2,517   Change in credit risk     (230 ) FX Impact     17   Balance at March 31, 2024   $ 9,341     Non-financial assets and liabilities The Company’s non-financial assets, which primarily consist of property and equipment and equity method investments, are not required to be measured at fair value on a recurring basis, and instead are reported at carrying value in its consolidated balance sheet. However, on a periodic basis or whenever events or changes in circumstances indicate that they may not be fully recoverable, the respective carrying value of non-financial assets are assessed for impairment and, if ultimately considered impaired, are adjusted and written down to their fair value, as estimated based on consideration of external market participant assumptions.

Convertible Notes	9 Months Ended

Debt Disclosure [Abstract]
Convertible Notes	8. Convertible Notes In April 2022, the Company issued amortizing senior convertible bonds with a principal amount of $21.2 million in amortizing senior convertible bonds due in April 2027 (the "Bonds") to Heights Capital Ireland LLC (the "Convertible Bond Investor"). The Bonds were issued at 85% par value with total net proceeds of $18.0 million and accrue interest at an annual rate of 5.5%, payable quarterly in arrears, in cash or American Depositary Shares ("ADSs") valued at the ADS Settlement Price at the option of the Company. The principal and interest payments are due in equal quarterly installments starting in July 2022. The Bonds contain various conversion and redemption features. The initial conversion price for the Bonds of $8.70 has been set at a 20 percent premium to the Reference ADS Price. The Conversion Price may reset down at 12, 24 and 36 months, depending on share price performance, and the Bonds have a hard floor in the conversion price of $7.25. As a result of the February 2023 private placement and pursuant to conditions of the bond agreement, the conversion price was adjusted to $8.2508 (previously $8.70) and the floor price was adjusted to $6.8757 (previously $7.25). Further, pursuant to conditions of the agreement, effective April 7, 2023, the conversion price was adjusted from $8.2508 to $7.7924. Between amortization dates, the Convertible Bond Investor retains the right to advance future amortization payments, provided that (a) there shall be no amortization advancements during the first 12 months, (b) no more than 2 amortization advancements may occur in any 12 month period, and (c) no more than 1 amortization advancement may occur in any 3 month period. On March 28, 2024, the Company entered into a second amendment and restatement agreement with the Convertible Bond Investor, which amended the terms of the Company’s existing bond agreement, dated March 31, 2022. The Bond Agreement Amendment amends the existing bond agreement to, among other things: • implement a beneficial ownership limitation whereby each bondholder, together with its affiliates, must not at any time own or acquire the beneficial ownership of more than 9.99% of the issued and outstanding ordinary shares of the Company; • adjust the bondholder’s’ maximum trading volume by removing a cap on the number of ADS that can be sold each day and reduces the length of certain non-trading periods applicable to the bondholders; • reduce certain market price observation periods to 5 days and 3 days (rather than 10 days and 5 days); • grant the holders of more than 50% of the principal amount of the bonds issued thereunder and then-outstanding (the “Majority Bondholders”) the right to defer the amortization payment scheduled for 7 April 2024 (the “April 2024 Amortized Payment Amount”) in addition to the deferrals already permitted as well as the right to accelerate the April 2024 Amortized Payment Amount if previously deferred in addition to the accelerations already permitted; and • in addition to the existing right to accelerate the next scheduled amortization payment, provide the Majority Bondholders the ability to accelerate any other future scheduled amortization payment, subject to certain limitations. The Company performed an analysis and determined that the financial impact was immaterial as the amended and restated agreement was not substantially different than the previous agreement. The Convertible Bond Investor is also permitted to defer up to two amortization payments to a subsequent amortization date. The Company retains the option to repay any deferred amortization in cash at 100 percent of the nominal amount. In July 2023, the Company made a cash amortization payment of $1.4 million, which consisted of $1.1 million of principal and $0.3 million of interest.

Significant assumptions used in the fair value analysis include the volatility rate, risk-free rate, dividend yield and risky yield. The fair value of the Bonds was determined to be $16.9 million on issuance, which is the principal amount of the Bonds.

Lessee Disclosure [Abstract]
Leases	9. Leases The Company leases certain office space and laboratory space. At the inception of an arrangement, the Company determines whether the arrangement is or contains a lease based on the unique facts and circumstances present. The Company does not recognize right-of-use assets or lease liabilities for leases determined to have a term of 12 months or less. Many of the Company's leases contain variable non-lease components such as maintenance, taxes, insurance, and similar costs for the spaces it occupies. Variable executory costs, as it relates to net leases, are excluded from the calculation of the lease liability. Variable executory costs include costs relating to utilities, repairs, maintenance, insurance, common area expenses, and taxes paid for the leased asset during its economic life. Upon adoption of ASC 842, the Company elected the package of practical expedients and the hindsight practical expedient but did not elect the easement practical expedient which is not applicable to the Company as the Company does not have any ground leases. In accordance with the package of practical expedients, the Company has not reassessed any of their existing or expired contracts or any other agreements that were previously concluded to not contain a lease for the following practical expedient guidance: (1) whether the arrangement is or contains a lease, (2) lease classification and (3) whether previously capitalized costs continue to qualify as initial direct costs. The Company leased lab space in Salt Lake City, UT, under a five-year lease, the term of which commenced in November 2019. The Company has measured its right-of-use assets and lease liabilities based on lease terms ending in October 2024. The Company performed a recoverability assessment and determined the entire $0.1 million right-of-use asset to be impaired and recorded a loss within the impairment loss on property, equipment, and other long-lived assets line of the statement of operations for the three and nine months ended March 31, 2024. The Company leased lab space in New York City, NY under an initial three-month lease, the term of which commenced in February 2019. The Company has classified this lease as a short-term lease as the Company concluded that the noncancelable terms of this lease was less than one year at the commencement and none of the Company's renewals or amendments were for additional noncancelable terms greater than one year. The Company leased lab space in St. Petersburg, FL from under an initial one-year term, the term of which commenced in January 2022. The Company has classified this lease as a short-term lease as the Company concluded that the noncancelable terms of this lease was less than one year at the commencement and none of the Company's renewals or amendments were for additional noncancelable terms greater than one year. The St. Petersburg, FL lease expired in the quarter ended March 31, 2024.

The lease did not have termination or formal renewal options however the Company can renew their office space if they are still needed and are still available at the end of the term. The Company has classified this lease as a short-term lease as the Company concluded that the noncancelable terms of this lease was less than one year at the commencement and none of the Company's renewals or amendments were for additional noncancelable terms greater than one year. The Company identified and assessed the following significant assumptions in recognizing its right-of-use assets and corresponding lease liabilities during the adoption of ASC 842: As the Company's leases do not provide an implicit rate, it concluded that a 10.0% IBR, the approximate midpoint between the average commercial real estate loans during 2022, is an appropriate discount rate to use for the Utah lease, which was the only lease existing as of the adoption date.

Share-Based Payment Arrangement [Abstract]
Share-based compensation	13. Share-based compensation Equity Incentive Plan In November 2018, Company established the Renalytix AI plc Share Option Plan (the “2018 Share Option Plan”) and a U.S. Sub-Plan and Non-Employee Sub-Plan. In July 2020, the Company's board of directors adopted and the Company's shareholders approved the 2020 Equity Incentive Plan (the “EIP”), which superseded the 2018 Share Option Plan. The equity incentive plan provides for the Company to grant options, restricted share awards and other share-based awards to employees, directors and consultants of the Company. As of March 31, 2024, there were 16,674,989 shares available for future issuance under the EIP. The EIP is administered by the board of directors. The exercise prices, vesting and other restrictions are determined at their discretion, except that all options granted have exercise prices equal to the fair value of the underlying ordinary shares on the date of the grant and the term of stock option may not be greater than ten years from the grant date. With respect to the options outstanding as of March 31, 2024: • 5,968,095 options vest equally over twelve quarters following the grant date; • 778,211 options vest 25% on the one year anniversary of the grant date and the remaining 75% equally over twelve quarters following the one year anniversary of the grant date; • 490,000 options vest one third on the one year anniversary of the grant date and the remaining two thirds equally over eight quarters following the one year anniversary of the grant date; • 295,000 options vest 25% at the end of the first quarter following Vesting Commencement Date and the remaining shares vest quarterly thereafter; • 287,750 options vest 25% on the one year anniversary of the grant date, 50% on the two year anniversary of the grant date, and 25% on the three year anniversary; • 285,000 options vest 12 months after the vesting commencement date; • 12,500 options vest quarterly over two years following the grant date; and • 10,000 options vested on the vesting commencement date. If options remain unexercised after the date one day before the tenth anniversary of grant, the options expire. On termination of employment, any options that remain unexercised are either forfeited immediately or after a delayed expiration period, depending on the circumstances of termination. Upon the exercise of awards, new ordinary shares are issued by the Company. The Company recorded share-based compensation expense in the following expense categories in the consolidated statements of operations for the three and nine months ended March 31, 2024 and 2023 (in thousands):     For the Three Months Ended March 31,     For the Nine Months Ended March 31,       2024     2023     2024     2023   Research and development   $ 72     $ 56     $ 249     $ 236   General and administrative   $ 311     $ 709     $ 1,037     $ 2,108   Cost of revenue   $ 2     $ 5     $ 8     $ 7     $ 385     $ 770     $ 1,294     $ 2,351       The fair value of options is estimated using the Black-Scholes option pricing model, which takes into account inputs such as the exercise price, the value of the underlying ordinary shares at the grant date, expected term, expected volatility, risk-free interest rate and dividend yield. The fair value of each grant of options during the three months ended March 31, 2024 and 2023 were determined using the methods and assumptions discussed below. • The expected term of employee options is determined using the “simplified” method, as prescribed in SEC’s Staff Accounting Bulletin No. 107, whereby the expected life equals the arithmetic average of the vesting term and the original contractual term of the option due to the Company’s lack of sufficient historical data. • The expected volatility is based on historical volatility of the publicly-traded common stock of a peer group of companies. • The risk-free interest rate is based on the interest rate payable on U.S. Treasury securities in effect at the time of grant for a period that is commensurate with the assumed expected term. • The expected dividend yield is none because the Company has not historically paid and does not expect for the foreseeable future to pay a dividend on its ordinary shares. For the nine months ended March 31, 2024 and 2023, the grant date fair value of all option grants was estimated at the time of grant using the Black-Scholes option-pricing model using the following weighted average assumptions:     For the Nine Months Ended March 31,       2024     2023   Expected term (in years)     6.3       6.1   Expected volatility     74.9 %     66.9 % Risk-free rate     4.3 %     3.2 % Dividend yield     — %     — %   The weighted average fair value of the options granted during the three and nine months ended March 31, 2024 and 2023 was $0.76 and $1.16 per share, respectively. The following table summarizes the stock option granted to employees and non-employees for the nine months ended March 31, 2024:     Number of shares under option plan     Weighted- average exercise price per option     Weighted- average remaining contractual life (in years)   Outstanding at June 30, 2023     4,968,576     $ 4.50       6.7   Granted     3,565,546     $ 1.05         Exercised     —     $ -         Forfeited     (406,003 )   $ 5.39         Expired     (1,563 )   $ 6.63         Outstanding at March 31, 2024     8,126,556     $ 2.93       7.4   Exercisable at March 31, 2024     4,745,811     $ 4.09       6.0   Vested and expected to vest at March 31, 2024     8,126,556     $ 2.93       7.4     As of March 31, 2024, there was $2.57 million in unrecognized compensation cost related to unvested options that will be recognized as expense over a weighted average period of 1.96 years. The aggregate intrinsic value of options outstanding and options exercisable at each of March 31, 2024 and March 31, 2023 was $0. Employee Share Purchase Plan The Company’s 2020 Employee Share Purchase Plan (the “ESPP”) became effective on August 17, 2020. The ESPP authorizes the issuance of up to 850,000 of the Company’s ordinary shares. The number of the Company's ordinary shares that may be issued pursuant to rights granted under the ESPP shall automatically increase on January 1st of each year, commencing on January 1, 2021 and continuing for ten years, in an amount equal to the lesser of one percent of the total number of the Company’s ordinary shares outstanding on December 31st of the preceding calendar year, and 2,000,000 ordinary shares, subject to the discretion of the board of directors or remuneration committee to determine a lesser number of shares shall be added for such year. Under the ESPP, eligible employees can purchase the Company’s ordinary shares through accumulated payroll deductions at such times as are established by the board of directors or remuneration committee. Eligible employees may purchase the Company’s ordinary shares at 85% of the lower of the fair market value of the Company’s ordinary shares on the first day of the offering period or on the purchase date. Eligible employees may contribute up to 15% of their eligible compensation. Under the ESPP, a participant may not purchase more than $25,000 worth of the Company’s ordinary shares for each calendar year in which such rights are outstanding. During the nine months ended March 31, 2024, 75,328 shares were purchased under the ESPP. During the nine months ended March 31, 2023, 298,086 shares were purchased under the ESPP. In accordance with the guidance in ASC 718-50 – Compensation – Stock Compensation, the ability to purchase shares of the Company’s ordinary shares at 85% of the lower of the price on the first day of the offering period or the last day of the offering period (i.e. the purchase date) represents an option and, therefore, the ESPP is a compensatory plan under this guidance. Accordingly, share-based compensation expense is determined based on the option’s grant-date fair value as estimated by applying the Black Scholes option-pricing model and is recognized over the withholding period. The Company recognized share-based compensation expense of $0.01 million during the nine months ended March 31, 2024 related to the ESPP. The Company did not recognize compensation expense related to the ESPP for the three months ended March 31, 2024. The Company recognized share-based compensation expense of $0.03 million and $0.08 million in the three and nine months ended March 31, 2023. Restricted Stock Units Activity for restricted stock units for the nine months ended March 31, 2024 is as follows:     Number of Restricted Stock Units     Weighted- average Grant Date Fair Value   Non-vested balance at June 30, 2023     40,340     $ 1.72   Granted     —     $ -   Vested     (21,290 )   $ 2.17   Forfeited     (9,315 )   $ 1.69   Non-vested balance at March 31, 2024     9,735     $ 0.93   The total fair value of restricted stock units vested during the three months ended March 31, 2024 was $0.01 million. Restricted stock units vest upon the achievement of time-based service requirements. At March 31, 2024, total unrecognized compensation expense related to non-vested restricted stock units was approximately $0.01 million. Unrecognized compensation expense relating to restricted stock units that are deemed probable of vesting is expected to be recognized over a weighted-average period of approximately 0.48 years.

Earnings Per Share [Abstract]
Net loss per ordinary share	15. Net loss per ordinary share Basic net loss per ordinary share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during each period. Diluted net loss per ordinary share includes the effect, if any, from the potential exercise or conversion of securities, such as options which would result in the issuance of incremental ordinary shares. Potentially dilutive securities outstanding as of March 31, 2024 and March 31, 2023 have been excluded from the computation of diluted weighted average shares outstanding as they would be anti-dilutive. Therefore, the weighted average number of shares used to calculate both basic and diluted net loss per share are the same. The following potentially dilutive securities have been excluded from the computation of diluted weighted-average shares of ordinary shares outstanding as they would be anti-dilutive:       For the Nine Months Ended March 31,       2024     2023   Stock options to purchase ordinary shares     8,126,556       4,977,699   Restricted stock units     19,470       179,960   Conversion of convertible note     4,625,019       2,071,264       12,771,045       7,228,923

Subsequent Events [Abstract]
Subsequent events	16. Subsequent events The Company has evaluated subsequent events from the condensed consolidated balance sheet date through the date at which the condensed financial statements were available to be issued, and determined there are no other items requiring disclosure beyond those disclosed below. On April 8, 2024, the Company announced a registered direct offering of ordinary shares at a purchase price equivalent to $0.75 per ADS ($0.375 per common stock share) (the "Fundraise"). The Fundraise was conducted by way of a securities purchase agreement between the Purchaser and the Company which consists of an initial tranche of 2,666,667 Ordinary Shares for gross proceeds of $1.0 million (the “Initial Tranche Shares”) with an optional subsequent tranche of Ordinary Shares at the option of the Purchaser. On April 22, 2024, the Company announced that of the Purchaser had exercised this option with respect to 1,333,334 Ordinary Shares (the "Subsequent Tranche Shares") at the same price as the Initial Tranche Shares, raising $0.5 million additional gross proceeds for the Company. On April 10, 2024, the Company announced the repayment of $1.1 million of the Company's Bond through the issuance of an aggregate of 3,636,162 ordinary shares in the form of 1,818,081 ADSs. 3,636,162 ordinary shares were issued to settle the conversion of 1,818,081 ADSs. As of May 15, 2024, the principal remaining under the Bond was $12.7 million. On April 25, 2024, the Company announced that the Second Tranche Placing Shares of 26,815,841 ordinary shares closed on April 24, 2024 (See Note 12). The Company's issued share capital consisted of 154,368,191 Ordinary Shares following the issuance of the Second Tranche Placing Shares of 26,815,841 Ordinary Shares.

Basis of presentation and summary of significant accounting policies (Policies)	9 Months Ended
	Mar. 31, 2024
Accounting Policies [Abstract]
Principles of consolidation	Principles of consolidation The consolidated financial statements include the accounts of Renalytix plc, and its wholly-owned subsidiaries. All inter-company balances and transactions have been eliminated in consolidation. The Company accounts for investments in which it has significant influence but not a controlling financial interest using the equity method of accounting.
Use of estimates	Use of estimates The preparation of the consolidated financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the consolidated financial statements and reported amounts of expenses during the reporting period. Actual results could differ from those estimates. Due to the uncertainty of factors surrounding the estimates or judgments used in the preparation of the consolidated financial statements, actual results may materially vary from these estimates. Estimates and assumptions are periodically reviewed, and the effects of revisions are reflected in the consolidated financial statements in the period they are determined to be necessary. Significant areas that require management’s estimate include the assumptions used in determining the fair value of share-based awards, determining the fair value of the bonds, recording the prepaid/accrual and associated expense for research and development activities performed for the Company by third parties and determining useful lives of property and equipment and capitalized software.
Segment information	Segment information The Company manages its operations as a single operating segment for the purposes of assessing performance and making operating decisions. The Company’s singular focus is to make significant improvements in kidney disease diagnosis and prognosis, clinical care, patient stratification for drug clinical trials, and drug target discovery.
Foreign currency	Foreign currency The Company’s consolidated financial statements are presented in U.S. dollars, the reporting currency of the Company. The functional currency of Renalytix plc and Renalytix AI Limited is GB Pounds. The functional currency of Renalytix AI, Inc. is the U.S. dollar. Assets and liabilities of Renalytix plc and Renalytix AI Limited are translated at the rate of exchange at period-end, while the statements of operations are translated at the weighted average exchange rates in effect during the reporting period. The net effect of these translation adjustments is shown as a component of accumulated other comprehensive loss. Transaction gains and losses resulting from exchange rate changes on transactions denominated in currencies other than the functional currency are included in income in the period in which the change occurs and reported in the consolidated statements of operations and comprehensive loss.
Concentrations of credit risk and major customers	Concentrations of credit risk and major customers Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and accounts receivable balances. Periodically, the Company maintains deposits in accredited financial institutions in excess of federally insured limits. The Company deposits its cash in financial institutions that it believes have high credit quality and are not exposed to any unusual credit risk beyond the normal credit risk associated with commercial banking relationships and has not experienced any losses on such accounts. The Company’s accounts receivables are derived from revenue earned from customers located in the U.S. For the nine months ended March 31, 2024, approximately 47% of all receivables related to KidneyIntelX testing revenue related to two customers and the remaining 53% of receivables were due from other third party payors. For the nine months ended March 31, 2023, approximately 73% of all receivables related to Mount Sinai, approximately 15% of all receivables related to Medicare claims and the remaining 12% of receivables were due from other third party payors. The Company performs initial and ongoing credit reviews on customers, which involve consideration of the customers’ financial information, their location, and other factors to assess the customers’ ability to pay and reserved for $0.1 million of receivables as of March 31, 2024.
Fair value of financial instruments	Fair value of financial instruments At March 31, 2024 and June 30, 2023, the Company’s financial instruments included accounts receivable, prepaid expenses and other current assets, accounts payable, accrued expenses and other current liabilities. The carrying amounts of these assets and liabilities approximates fair value due to their short-term nature. The convertible notes are recorded at their estimated fair value.
Fair value option	Fair value option Under the Fair Value Option Subsections of ASC subtopic 825-10, Financial Instruments – Overall, the Company has the irrevocable option to report most financial assets and financial liabilities at fair value on an instrument-by-instrument basis, with changes in fair value reported in earnings (see Note 5). The Company has elected to measure and record the convertible notes at their estimated fair value.
Cash and cash equivalents	Cash and cash equivalents The Company considers all highly liquid investments purchased with an original maturity of 90 days or less to be cash equivalents. As of March 31, 2024 and June 30, 2023, the Company had cash and cash equivalents of $4.7 million and $24.7 million, respectively.
Accounts receivable	Accounts receivable Accounts receivable are recorded at the invoice amount and are non-interest bearing. The Company estimates expected credit losses of its accounts receivable by assessing the risk of loss and available relevant information about collectability, including historical credit losses, existing contractual payment terms, actual payment patterns of its customers, individual customer circumstances, and reasonable and supportable forecast of economic conditions expected to exist throughout the contractual life of the receivable. The Company reserved for $0.1 million of receivables as of March 31, 2024. The Company reserved for $0.1 million of receivables as of June 30, 2023.
Property, equipment and other long-lived assets	Property, equipment and other long-lived assets Property and equipment are recorded at cost. Depreciation is determined using the straight-line method over the estimated useful lives ranging from three to ten years. Expenditures for maintenance and repairs are expensed as incurred while renewals and betterments are capitalized. When property and equipment are sold or otherwise disposed of, the cost and related accumulated depreciation are eliminated from the accounts and any resulting gain or loss is reflected in operations. In November 2023, the Company consolidated lab operations which resulted in a $0.3 million impairment of property and equipment at the Company's Utah lab. In February 2024, the Company performed a recoverability assessment and determined the entire $0.1 million right-of-use asset related to the Utah lease to be impaired, and in addition the Company further consolidated lab operations which resulted in a $0.3 million impairment of property and equipment at the Company's Florida lab. The Company recorded a $0.4 million impairment of property, equipment and other long-lived assets for the three months ended March 31, 2024 and a $0.7 million impairment for the nine months ended March 31, 2024. There was no impairment loss on property, equipment and other long-lived assets in the nine months ended March 31, 2023.
Investments	Investments VericiDx plc The Company accounts for its ownership of VericiDx securities at fair value in accordance with ASC 321, Investments-Equity Securities, with changes in fair value recorded in earnings as the fair value of VericiDx's ordinary shares is readily determinable via the London Stock Exchange. Based on the closing stock price of VericiDx, the fair value of the investment in VericiDx was $1.1 million and $1.5 million at March 31, 2024 and June 30, 2023, respectively. In March 2024, the Company sold 750,000 ordinary shares of VericiDx for net proceeds of $0.1 million and a realized loss of $0.1 million. The Company did not sell any shares during the three and nine months ended March 31, 2023. During the three months ended March 31, 2024 and 2023, the Company recorded an increase in fair value of $0.04 million and $0.1 million, respectively, in the consolidated statements of operations and comprehensive loss. During the nine months ended March 31, 2024 and 2023, the Company recorded a decrease in fair value of $0.2 million and $1.1 million, respectively, in the consolidated statements of operations and comprehensive loss. The Company owned 3.7% of the ordinary shares of VericiDx at March 31, 2024, and owned 5.8% of ordinary shares of VericiDx at June 30, 2023.
Impairment assessment	Impairment assessment The Company evaluates its investments that are in unrealized loss positions, if any, and equity method investments for other-than-temporary impairment on a quarterly basis (see Note 5). Such evaluation involves a variety of considerations, including assessments of the risks and uncertainties associated with general economic conditions and distinct conditions affecting specific issuers or investees. Factors considered by the Company include (i) the length of time and the extent to which an investment’s fair value has been below its cost; (ii) the financial condition, credit worthiness, and near-term prospects of the issuer; (iii) the length of time to maturity; (iv) future economic conditions and market forecasts; (v) the Company’s intent and ability to retain its investment for a period of time sufficient to allow for recovery of market value; (vi) an assessment of whether it is more likely than not that the Company will be required to sell its investment before recovery of market value; and (vii) whether events or changes in circumstances indicate that the investment’s carrying amount might not be recoverable.
Software development costs	Software development costs The Company follows the provisions of ASC 985, Software, which requires software development costs for software marketed externally to be expensed as incurred until the establishment of technological feasibility, at which time those costs are capitalized until the software is available for general release and amortized over its estimated useful life of ten years. For the three and nine months ended March 31, 2024 and 2023, there was no capitalization of research and development expenses related to software development to record. Technological feasibility is established upon the completion of a working model that has been validated.
Revenue recognition	Revenue recognition Pursuant to ASC 606, Revenue from Contracts with Customers, the Company recognizes revenue when a customer obtains control of promised goods or services. The Company records the amount of revenue that reflects the consideration that it expects to receive in exchange for those goods or services. The Company applies the following five-step model in order to determine this amount: (i) identification of the promised goods or services in the contract; (ii) determination of whether the promised goods or services are performance obligations, including whether they are distinct in the context of the contract; (iii) measurement of the transaction price, including the constraint on variable consideration; (iv) allocation of the transaction price to the performance obligations; and (v) recognition of revenue when (or as) the Company satisfies each performance obligation. The Company only applies the five-step model to contracts when it is probable that it will collect the consideration to which it is entitled in exchange for the goods or services that it transfers to the customer. Once a contract is determined to be within the scope of ASC 606 at contract inception, the Company reviews the contract to determine which performance obligations it must deliver and which of these performance obligations are distinct. Certain contracts have options for the customer to acquire additional services. The Company evaluates these options to determine if a material right exists. If, after that evaluation, it determines a material right does exist, it assigns value to the material right based upon the renewal option approach. The Company recognizes as revenue the amount of the transaction price that is allocated to each performance obligation when that performance obligation is satisfied or as it is satisfied. The Company uses the present right to payment principle and customer acceptance as indicators to determine the transfer of control to the customer occurs at a point in time. Sales tax and other similar taxes are excluded from revenues.
Cost of revenue	Cost of revenue Cost of revenue consists of costs directly attributable to the services rendered, including labor, rent, lab consumables, depreciation, amortization and sample collection costs directly related to revenue generating activities.
Research and development expenses	Research and development expenses Research and development costs consist primarily of internal and external labor costs incurred in connection with the development of KidneyIntelX as well as expenses related to studies and clinical trials to further the clinical value, performance and utility of KidneyIntelX. Research and development costs are expensed as incurred.
Share-based compensation	Share-based compensation The Company measures equity classified share-based awards granted to employees and nonemployees based on the estimated fair value on the date of grant and recognizes compensation expense of those awards over the requisite service period, which is the vesting period of the respective award. The Company accounts for forfeitures as they occur. For share-based awards with service-based vesting conditions, the Company recognizes compensation expense on a straight-line basis over the service period. The fair value of each stock option grant is estimated on the date of grant using the Black-Scholes option-pricing model, which requires inputs based on certain subjective assumptions, including the expected stock price volatility, the expected term of the option, the risk-free interest rate for a period that approximates the expected term of the option, and the Company’s expected dividend yield. The Company was a privately-held organization prior to November 2018 and has been a publicly-traded company for a limited period of time and therefore lacks company-specific historical and implied volatility information for its shares. Therefore, it estimates its expected share price volatility based on the historical volatility of publicly-traded peer companies and expects to continue to do so until such time as it has adequate historical data regarding the volatility of its own traded share price. The expected term of the Company’s stock options has been determined utilizing the “simplified” method for awards that qualify as “plain-vanilla” options. The risk-free interest rate is determined by reference to the U.S. Treasury yield curve in effect at the time of grant of the award for time periods approximately equal to the expected term of the award. Expected dividend yield is none based on the fact that the Company has never paid cash dividends on ordinary shares and does not expect to pay any cash dividends in the foreseeable future. The Company classifies share-based compensation expense in its consolidated statement of operations and comprehensive loss in the same manner in which the award recipient’s payroll costs are classified or in which the award recipient’s service payments are classified.
Income taxes	Income taxes Income taxes are accounted for under the asset and liability method as required by FASB ASC Topic 740, Income Taxes (ASC 740). Deferred tax assets and liabilities are recognized for the future tax consequences attributable to differences between the financial statement carrying amounts of existing assets and liabilities and their respective tax bases and operating loss and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date. A reduction in the carrying value of the deferred tax assets is required when it is not more likely than not that such deferred tax assets are realizable. FASB ASC Subtopic 740-10, Accounting for Uncertainty of Income Taxes (ASC 740-10), defines the criterion an individual tax position must meet for any part of the benefit of the tax position to be recognized in financial statements prepared in conformity with U.S. GAAP. The Company may recognize the tax benefit from an uncertain tax position only if it is more likely than not such tax position will be sustained on examination by the taxing authorities, based solely on the technical merits of the respective tax position. The tax benefits recognized in the financial statements from such a tax position should be measured based on the largest benefit having a greater than 50% likelihood of being realized upon ultimate settlement with the tax authority. In accordance with disclosure requirements of ASC 740-10, the Company’s policy on income statement classification of interest and penalties related to income tax obligations is to include such items as part of income tax expense. The Company recorded an immaterial provision for income taxes for the three and nine months ended March 31, 2024. The Company did not record a provision for income taxes for the three and nine months ended March 31, 2023, as the Company generated losses for such periods. The Company periodically evaluates the realizability of its deferred tax assets based on all available evidence, both positive and negative. The realization of deferred tax assets is dependent on the Company’s ability to generate sufficient future taxable income during periods prior to the expiration of tax attributes to fully utilize these assets. The Company weighed both positive and negative evidence and determined that there is a continued need for a full valuation allowance on its deferred tax assets as of March 31, 2024. Should the Company determine that it would be able to realize its remaining deferred tax assets in the foreseeable future, an adjustment to its remaining deferred tax assets would cause a material increase to income in the period such determination is made.
Comprehensive loss	Comprehensive loss Comprehensive loss includes net loss as well as other changes in shareholders’ equity that result from transactions and economic events other than those with shareholders. For the periods presented, changes in shareholders’ equity include foreign currency translation as well as changes in fair value of the convertible note due to changes in instrument specific credit risk. The change in instrument specific credit risk was calculated as the change in the risk yield from the convertible debt issuance date to the valuation date. The instrument specific credit risk at issuance date was calibrated such that the fair value of the convertible bond was equal to the issue price as of the issuance date. The risk yield was adjusted to reflect the change in credit spreads between the issuance date and the valuation date.
Net loss per ordinary share	Net loss per ordinary share Basic net loss per ordinary share is computed by dividing net loss by the weighted average number of ordinary shares outstanding during each period. Diluted net loss per ordinary share includes the effect, if any, from the potential exercise or conversion of securities, such as options and convertible debt which would result in the issuance of incremental ordinary shares. The dilutive effect of convertible securities is calculated using the if-converted method. Under the if-converted method, interest charges applicable to the convertible debt as well as nondiscretionary adjustments which include any expenses or charges that are determined based on the income (loss) for the period are added back to net income. The convertible debt is assumed to have been converted at the beginning of the period (or at time of issuance, if later). For the three and nine months ended March 31, 2024, under the if-converted method, the add back of nondiscretionary adjustments and inclusion of potentially converted shares would be anti-dilutive.
Emerging growth company	Emerging growth company The Company is an emerging growth company as defined in the Jumpstart Our Business Startups Act of 2012, as amended (the “JOBS Act”). Under the JOBS Act, companies have extended transition periods available for complying with new or revised accounting standards. The Company has elected to avail itself of this exemption and, therefore, while the Company is an emerging growth company it will not be subject to new or revised accounting standards at the same time that they become applicable to other public emerging growth companies that have not elected to avail themselves of this exemption.
Recently issued accounting pronouncements	Recently issued accounting pronouncements In June 2016, the FASB issued ASU 2016-13, Financial Instruments—Credit Losses: Measurement of Credit Losses on Financial Instruments, which requires measurement and recognition of expected credit losses for financial assets held at the reporting date based on historical experience, current conditions, and reasonable and supportable forecasts. This is different from the previous guidance as this will require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. The Company implemented ASU 2016-13 in the fiscal year beginning July 1, 2023 and evaluated the impact of ASU 2016-13 and it did not have a material impact on the consolidated financial statements. In August 2020, the FASB issued ASU 2020-06, Debt - Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging - Contracts in Entity’s Own Equity (Subtopic 815-40), Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity (“ASU 2020-06”). ASU 2020-06 eliminates two of the three models in ASC 470-20 that require issuers to separately account for embedded conversion features and eliminates some of the requirements for equity classification in ASC 815-40-25 for contracts in an entity’s own equity. The guidance also requires entities to use the if-converted method for all convertible instruments in the diluted earnings per share calculation and generally requires them to include the effect of potential share settlement for instruments that may be settled in cash or shares. It is effective for annual periods beginning after December 15, 2023, and interim periods therein. The Company evaluated the effect of ASU 2020-06 and it is not expected to have a material impact on the consolidated financial statements.
