**Renalytix plc**

**("Renalytix" or the "Company")**

**Renalytix Reports Second Quarter and First Half Fiscal Year 2023 Financial Results**

**LONDON and SALT LAKE CITY, March 30, 2023** – Renalytix plc (NASDAQ: RNLX) (LSE: RENX), an artificial intelligence-enabled in vitro diagnostics company, focused on optimizing clinical management of kidney disease to drive improved patient outcomes and advance value-based care, today reported financial results for the fiscal second quarter and first half ended December 31, 2022.

**Recent Highlights (including post period events)**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Expanded insurance coverage for KidneyIntelX including:

oOne of the largest not-for-profit health insurers covering over three million lives in the Northeast U.S.

oLargest private payer in Illinois with over eight million members

o35 state Medicaid plans including recent additions of Texas and Florida

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Achieved Medicare payment for KidneyIntelX through the individual claims review (ICR) process based on our Medicare clinical lab fee schedule (CLFS) pricing of $950 per test

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Over 2,500 KidneyIntelX tests performed in the first half year of fiscal 2023 of which over 80% were billable

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Increasing diversity of commercially billable testing volume, particularly among primary care physician practices ordering through the MyIntelX portal

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Continued progress with FDA De Novo authorization review; FDA has indicated a target date for completion in the second calendar quarter of 2023

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Completed $20.3 million equity financing led by new institutional investors

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Core participant in $10 million Horizon Europe Grant to advance personalized medicine in treating chronic kidney disease

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Agreement with Veterans Administration to integrate KidneyIntelX testing with VA hospital electronic health record systems

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Publication of new real-world evidence in Journal of Primary Care and Community Health in which KidneyIntelX resulted in a 4.5-fold increase in new drug prescriptions (for SGLT2 inhibitors) for high-risk compared to low-risk patients; early evidence suggested that the introduction of SGLT2i contributed to an observed reduction in HbA1c levels most notably in high-risk patients, and a more than a 20% change in dose or type of antihypertensive therapeutic prescriptions in high vs. low-risk patients

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•KidneyIntelX clinical utility and health economics validated in multiple data releases at American Society of Nephrology Kidney Week 2022, and multiple presentations on clinical utility data accepted for presentation at National Kidney Foundation Spring Clinical Meeting 2023, American Diabetes Association 83rd Scientific Session, and American Association of Nurse Practitioners Annual Meeting, including data from Wake Forest, Mount Sinai, UPenn, and CANVAS cohorts

**Second Quarter 2023 Financial Results**

During the three months ended December 31, 2022, the Company recognized $1.2 million of revenue (Q1 FY22: $0.8 million). Cost of revenue for the three months ended December 31, 2022 was $0.7 million (Q1 FY22: $0.5 million).

Operating expense for the three months ended December 31, 2022 was $10.1 million compared with $14.1 million during the prior year period. As stated in August, we have taken action to lower annual expenditures by over $12 million through program, vendor and employee reductions, with additional opportunities to reduce expenditures under review.

Within operating expenses, research and development expenses were $3.3 million for the three months ended December 31, 2022, a decrease of $0.8 million, from $4.1 million for the three months ended December 31, 2021. The decrease was primarily due to a $1.6 million decrease in external consulting and professional fees, offset by a $0.8 million increase in employee related expenses.

General and administrative expenses were $6.8 million for the three months ended December 31, 2022, decreasing by $3.3 million from $10.1 million for the three months ended December 31, 2021. The decrease was due to the cost reduction measures taken earlier this year resulting in a $1.5 million decrease in consulting and professional fees, a $1.0 million decrease in employee related expenses, a $0.5 million decrease in insurance expense, and a $0.3 million decrease in other operating expenses.

Net loss was $10.4 million for the three months ended December 31, 2022 compared with $15.3 million for the prior year period.

Cash and cash equivalents totaled $23.8 million as of December 31, 2022.

**OPERATIONAL REVIEW**

**About Renalytix**

At Renalytix, we are introducing more accurate prognosis and effective care management for the estimated 850 million people worldwide with chronic kidney disease. In the United States alone, chronic kidney disease affects about 37 million people and is responsible for one of the largest cost drivers in the national medical system. Early identification, prognosis and treatment beginning with primary care is essential if we are to stem the growing social cost and suffering associated with kidney disease.

With our lead product, KidneyIntelX, the goal is to drive the focus from kidney disease treatment to kidney health management through a more accurate understanding of a patient's risk for kidney failure before it happens. KidneyIntelX leads development in the new field of bioprognosis, a biology driven approach to risk assessment that integrates information from a simple blood draw and a patient's health record to produce an accurate picture of kidney health. A doctor can use KidneyIntelX results to act on patients at high risk of kidney disease progression or failure at an early stage where active management and therapeutics have the best opportunity to impact outcomes and cost before it is too late.

**About KidneyIntelX**

Our novel platform, KidneyIntelX, uses a machine-learning enabled algorithm to process predictive blood biomarkers with key features from a patient's health record to generate an early and accurate kidney health risk score. The score identifies those patients at the most risk for kidney disease progression and/or failure and further guides ongoing clinical decisions.

KidneyIntelX is initially indicated for use with adults who have diagnosed kidney disease and diabetes – diabetic kidney disease or DKD. Future KidneyIntelX products in development intend to expand the indicated uses to include broader chronic kidney disease, health equity strategies and kidney health monitoring through treatment. Diabetes is the leading cause of chronic kidney disease, representing nearly 40% of its cases, and DKD patients are the highest contributors to emergency room dialysis starts. Unfortunately, many DKD patients are unaware that their kidney disease has been progressing, often uncontrolled, for many years and now find themselves making difficult decisions about late-stage treatments.

KidneyIntelX was designed as an expandable platform able to add indicated uses and a monitoring capability, all within an FDA regulated, insurance reimbursable framework.

**Operational Progress**

Over the last several months, we have made continued progress in establishing the commercial foundation for KidneyIntelX.

Progressing towards "super-majority" insurance coverage in multiple regional markets with large prevalence of diabetes and kidney disease

We are demonstrating payment success across a diverse cohort of insurance entities including individual state Blue Cross Blue Shield and Medicaid plans, Medicare Advantage, and other large for-profit and not-for profit insurance plans. Together with the recently awarded individual claim review payment from Medicare contractor National Government Services, this growing diversity in payment is providing us with the basis to expect that KidneyIntelX will continue to achieve majority coverage in markets with large populations of diabetes and kidney disease patients during calendar 2023. As a result, we are now able to concentrate resources and focus on building sales, marketing, and customer service functions to support test adoption in regions with comprehensive insurance coverage.

Establishing comprehensive insurance in metropolitan New York has allowed us to proceed with the important milestone of converting to a long term commercial reimbursement model with Mount Sinai Health System in our fiscal third quarter of this year (quarter ending March 31, 2023). As discussed below, this conversion from Mount Sinai as the sole payor of tests performed under the real-world evidence program begun in 2021 is timely in the March quarter.

------

The Centers for Medicare & Medicaid Services set the price for KidneyIntelX at $950 in 2019. To date, we have matched or exceeded the Medicare price when negotiating commercial insurance coverage contracts. To broaden access, we maintain a robust patient assistance program for those patients who have limited insurance coverage and for whom KidneyIntelX is indicated as a test. We are particularly conscious of the health inequity which is pervasive among diabetes and kidney disease populations and endeavor to expand access to the advanced prognosis benefits of KidneyIntelX wherever possible and permitted under the law.

We believe the diversity and depth of established insurance payment remains critical to establishing long-term testing adoption and revenue growth and is a unique feature of our business strategy in a relatively short time period since commercial testing launch.

Continuing to publish on our growing real-world evidence of KidneyIntelX effectiveness

We continue to accumulate longitudinal data from our real-world evidence program leading to further peer-reviewed support of the positive impact of KidneyIntelX. Published utility study results in the Journal of Primary Care Community Health on November 28, 2022 on 1,686 patients showed that primary care physicians using KidneyIntelX were 4.5 times more likely to prescribe advanced medication to their high-risk patients in early-stage kidney disease, where the opportunity to prevent significant kidney damage or kidney failure is greatest, as compared to their low-risk patients. Additionally, providers were nearly 2.5 times more likely to make a timely referral to a specialist in high-risk patients compared to low-risk patients, and 20% more likely to initiate more adaptive and aggressive anti-hypertensive(blood pressure control) strategies in these high risk patients. Notable clinical observations from this study showed improvements in HbA1C levels for diabetes glucose control in the high-risk group in the first six months, most likely the result of both increased patient engagement combined with appropriate medication changes. There was also a 15% improvement in UACR (urine albumin to creatinine ratio), an important indicator of kidney health, at the six-month mark in the low- and intermediate-risk groups.

This evidence builds on a previously published study in the American Journal of Managed Care (AJMC) that indicated that 98% of PCPs were somewhat, very or extremely likely to use KidneyIntelX to predict which of their patients with DKD will experience rapid progressive decline in their kidney function. We believe this investment in real-world evidence is driving positive insurance reimbursement decisions, and will eventually help support inclusion of KidneyIntelX in key clinical guidelines for diabetes and kidney health.

We are also pleased to be a core member of a consortium of industry, academic and clinical research leaders awarded a $10 million Horizon Europe Grant to advance personalized medicine in treating chronic kidney disease. The consortium, PRIME-CKD, aims to validate and implement in clinical practice, novel biomarker-based tests that predict response to existing drugs used by patients with chronic kidney disease (CKD). PRIME-CKD is funded by Horizon Europe, the European Union's key funding program for research and innovation. The total budget of the project is $10 million over a projected five-year period, with approximately 10% of the budget targeted for commercial translation activities to be undertaken by Renalytix. The project is closely aligned with Renalytix's objective of expanding the clinical utility of the KidneyIntelX platform beyond prognosis to prediction and monitoring of drug response.

Pursuing Food and Drug Administration (FDA) De Novo marketing authorization for KidneyIntelX

We continue to make progress toward De Novo marketing authorization of KidneyIntelX with the Food and Drug Administration. While there are no guarantees, we remain optimistic and are working diligently with the FDA towards a successful outcome. FDA has indicated they are working towards a decision by the end of second calendar quarter of 2023. As part of the De Novo process, and pending a successful outcome of the review, the FDA will prepare a reclassification order and pursue certain internal processes for this class of test prior to communicating the final decision. The comprehensive data dossier submitted and detailed review process by the FDA is reflective of the breakthrough nature of this novel test.

Mount Sinai billing transition

In our fiscal third quarter (quarter ending March 31, 2023) we completed the milestone of transitioning to a long-term commercial insurance payment model for patients tested at the Mount Sinai Health System. This transition is taking place with the completion of the applicable portion of the 2018 license agreement under which Mount Sinai covered the cost of the first six million dollars of KidneyIntelX testing as part of a real-world evidence study.

Our ability to secure diversity of commercial insurance for KidneyIntelX for a significant portion of the diabetes and kidney disease population in New York City would not be possible without established payment from Medicare, Medicare Advantage and other large New York City concentrated payors. This includes a recently disclosed coverage contract with the second largest non-profit payer in the United States with 3.2 million members and another coverage contract secured with a large value-based care insurer covering 1.8 million members. We are now experiencing a high-rate of payment across both public and private insurance carriers in the New York region at or above our established Medicare pricing of $950 per reportable result.

The transition to commercial payment for testing at Mount Sinai will have a short-term adverse impact on testing volumes, predominantly in the month of March. Further, as is customary when diagnostic products move to broad-scale commercial billing, the average selling price for KidneyIntelX will now include a minority percentage of discounted testing for patients qualifying for financial assistance and out-of-network testing.

Further, we have begun to experience the validatory effects of establishing commercial pay after extensive real-world experience with a system as large and influential as Mount Sinai with other key insurers and health systems looking to adopt a KidneyIntelX guided clinical management program for patients with diabetes and kidney disease.

------

Other commercial market development

Continued diversity of insurance coverage, successful real-world evidence and a positive FDA decision will be important factors in the quarters ahead to drive testing adoption and revenue growth. We are pleased to begin seeing a more diverse group of physicians in different locations in the United States ordering KidneyIntelX. We are assessing more focused hiring of primary care sales and medical science liaison personnel for deployment in areas with established insurance payment.

We entered into an agreement with the Veterans Administration to install the KidneyIntelX solution inside the VA Health System's cloud infrastructure and interface it with the VA electronic health record systems. This marks a significant milestone in ultimately enabling providers at VA Medical Centers and outpatient clinics to order and receive test results in a seamless manner, and eventually make KidneyIntelX accessible to large numbers of veterans with diabetic kidney disease.

Financing

In March of last year, we announced the completion of a financing package yielding $26.8 million in gross proceeds for the Company. The financing included an $8.8 million equity subscription plus $21.2 million principal amount of convertible bonds (net cash proceeds of $18 million).

In February 2023, post period end, the Company raised an additional $20.3 million gross proceeds in a private placement of ordinary shares and American Depositary Shares.

We are pleased to have achieved such financings during this challenging capital market environment, which we believe illustrates the strength of our kidney disease testing, monitoring and informed care advantages. In these rounds, we have welcomed substantial new institutional investors alongside participation by longstanding shareholders.

Current Trading and Outlook

Our fundamental goals remain clear:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Build testing adoption on a regional basis;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Continue to secure diversified, long-term insurance coverage;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Continue building evidence of real-world benefit of KidneyIntelX use; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•Obtain FDA marketing authorization

We believe the early-stage kidney health market remains largely un-tapped and open for innovation. Renalytix is in a position to alter both the fundamental cost of care in the short and long-term, maintain better health for millions of Americans with diabetes and kidney disease, and reduce the threat of unexpected kidney failure and dialysis. With the World Obesity Federation reporting in March that 51% of the global population, or more than 4 billion people, are expected to be overweight or obese by 2035, kidney disease and diabetes which run in parallel will remain significant threats to the global health care system. Now more than ever, we will need a way to understand who is at risk for advancing kidney disease (and importantly who is not), and to whom new effective medication should be given and how they respond. Without a KidneyIntelX-like prognosis available at the front end of chronic kidney disease, easily implemented and understood by primary care physicians, it will be very challenging to allocate medical resource efficiently, and alert patients and their doctors to preventive measures to preserve health.

We believe we are in the process of validating a new standard with KidneyIntelX that can be used by any physician in any healthcare environment for preventative medicine, with high-quality standards verified by third-party experts and regulatory agencies, tested extensively in the real-world and, of course, covered by a diverse set of insurance payors.

As discussed earlier in this section, during the current third fiscal quarter of 2023, we have secured important new commercial insurance coverage for KidneyIntelX, held constructive interactions with the FDA regarding our De Novo application, enhanced our balance sheet with new funding, and executed an important transition at Mount Sinai to third-party commercial billing.

**FINANCIAL REVIEW**

**Financial review of the three-month period ended December 31, 2022 and comparison to prior year period**

Our operating loss for the three months ended December 31, 2022, was $9.6 million (December 31, 2021: $13.8 million).

**Revenue**

During the three months ended December 31, 2022, we recognized $1.0 million of revenue related to KidneyIntelX testing and $0.2 million of revenue related to pharmaceutical services. There was $0.6 million of revenue related to KidneyIntelX testing and $0.2 million of revenue related to pharmaceutical services for the three months ended December 31, 2021.

**Cost of Revenue**

During the three months ended December 31, 2022, cost of revenue consisted of $0.7 million primarily attributable to KidneyIntelX testing, including labor and materials costs directly related to revenue generating activities. There was $0.5 million of cost of revenue for the three months ended December 31, 2021.

------

**Research and Development Costs**

Research and development expenses decreased by $0.8 million, from $4.1 million for the three months ended December 31, 2021 to $3.3 million for the three months ended December 31, 2022. The decrease was primarily due to a $1.6 million decrease in external consulting and professional fees, offset by a $0.8 million increase in employee related expenses.

**General and Administrative Costs**

General and administrative expenses decreased by $3.3 million, from $10.1 million for the three months ended December 31, 2021 to $6.8 million for the three months ended December 31, 2022. The decrease was due to the cost reduction measures taken earlier this year resulting in a $1.5 million decrease in consulting and professional fees, a $1.0 million decrease in employee related expenses, a $0.5 million decrease in insurance expense, and a $0.3 million decrease in other operating expenses.

**Foreign Currency loss**

During the three months ended December 31, 2022, we recorded an unrealized foreign exchange loss of $0.1 million primarily attributable to cash balances denominated in currencies other than the functional currency. We recorded an unrealized foreign currency loss of $0.2 million during the three months ended December 31, 2021.

**Fair Value Adjustments to VericiDx Investment**

The Company accounts for the investment in VericiDx equity securities at fair value, with changes in fair value recognized in the income statement. During the three months ended December 31, 2022, we recorded a loss of $0.3 million to adjust the VericiDx investment to fair value. We recorded a loss of $1.4 million during the three months ended December 31, 2021.

**Fair Value Adjustment on Convertible Notes**

In April 2022, the Company issued amortizing senior convertible bonds with a principal amount $21.2 million due in April 2027 (the "Bonds"). We elected to account for the bonds at fair value with qualifying changes in fair value recognized through the statements of operations until the notes are settled. This excludes fair value adjustments related to instrument-specific credit risk, which are recognized in OCI. For the three months ended December 31, 2022, we recorded a loss of $0.4 million to adjust the bonds to fair value. There was no fair value adjustment for the three months ended December 31, 2021 as we had not issued convertible debt at that time.

**Other income**

During the three months ended December 31, 2022, we realized $0.06 million of interest income and $0.04 million of other income related to Kantaro. There was no other income recorded during the three months ended December 31, 2021.

**Financial review of the six months ended December 31, 2022 and comparison to prior year period**

Our operating loss for the six months ended December 31, 2022, was $21.4 million (December 31, 2021: $25.6 million).

**Revenue**

During the six months ended December 31, 2022, we recognized $2.0 million of revenue related to KidneyIntelX and $0.2 million of revenue related to services performed for AstraZeneca. There was $1.1 million of revenue related to KidneyIntelX and $0.2 million of revenue related to services performed for AstraZeneca for the six months ended December 31, 2021.

**Cost of Revenue**

During the six months ended December 31, 2022, cost of revenue consisted of $1.4 million primarily attributable to KidneyIntelX testing, including labor and materials costs directly related to revenue generating activities. There was $0.7 million of cost of revenue for the six months ended December 31, 2021.

**Research and Development Costs**

Research and development expenses decreased by $1.0 million, from $8.1 million for the six months ended December 31, 2021 to $7.1 million for the six months ended December 31, 2022. The decrease was primarily due to a $1.5 million decrease in external consulting and professional fees, offset by a $0.5 million increase in employee related expenses.

**General and Administrative Costs**

General and administrative expenses decreased by $3.1 million, from $18.2 million for the six months ended December 31, 2021 to $15.1 million for the six months ended December 31, 2022. The decrease was primarily due to a $1.6 million decrease in consulting and professional fees, a $1.0 million decrease in insurance expense, a $0.4 million decrease in employee related expenses, a $0.2 million decrease in software and IT costs, offset by a $0.1 million increase in other operating expenses.

**Foreign Currency Gain (Loss)**

During the six months ended December 31, 2022, we recorded an unrealized foreign exchange gain of $0.7 million primarily attributable to intercompany loans and cash balances denominated in currencies other than the functional currency. We recorded a foreign currency gain of $2.1 million during the six months ended December 31, 2021.

------

**Fair value adjustment on convertible notes**

In April 2022, the Company issued amortizing senior convertible bonds with a principal amount $21.2 million due in April 2027 (the "Bonds"). We elected to account for the bonds at fair value with qualifying changes in fair value recognized through the statements of operations until the notes are settled. This excludes fair value adjustments related to instrument-specific credit risk, which are recognized in OCI. For the six months ended December 31, 2022, we recorded a loss of $0.7 million to adjust the bonds to fair value. There was no fair value adjustment for the six months ended December 31, 2021 as we had not issued convertible debt at that time.

**Other income**

During the three months ended December 31, 2022, we realized $0.1 million of interest income and $0.1 million of other income related to Kantaro. There was less than $0.1 million of other income recorded during the three months ended December 31, 2021.

**Fair Value Adjustments to VericiDx Investment**

We account for our investment in VericiDx using the equity method of accounting and have elected to use the fair value option to value the investment. During the six months ended December 31, 2022, we recorded a loss of $2.0 million to adjust the VericiDx investment to fair value. We recorded a loss of $2.0 million during the six months ended December 31, 2021.

**Liquidity and Capital Resources**

Since our inception, we have incurred net losses. As of December 31, 2022, we had an accumulated deficit of $155.6 million.

We expect to incur additional losses in the near future, and we expect our expenses to increase 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 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 continue 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:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the cost, progress and results of our ongoing and planned validation studies and health economic studies;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the cost, timing and outcome of entering into and maintaining partnership agreements with healthcare systems for the commercial sale of KidneyIntelX;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the cost of manufacturing clinical and commercial supply of KidneyIntelX;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the cost, timing and outcome of regulatory review of KidneyIntelX, including any post-marketing studies that could be required by regulatory authorities;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the cost, timing and outcome of identified and potential future commercialization activities, including manufacturing, marketing, sales and distribution, for KidneyIntelX;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the costs and timing of preparing, filing and prosecuting patent applications, maintaining and enforcing our intellectual property rights and defending any intellectual property-related claims, including any claims by third parties that we are infringing upon their intellectual property rights;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the timing and amount of future revenue, if any, received from commercial sales of KidneyIntelX;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the sales price and availability of adequate third-party coverage and reimbursement for KidneyIntelX;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the effect of competing technological and market developments; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;•the extent to which we acquire or invest in businesses, products and technologies, such as Kantaro, although we currently have no other commitments or agreements to complete any such transactions.

To date, we have primarily financed our operations through equity and debt financings. As of December 31, 2022, we had cash and cash equivalents of $23.8 million. We believe that our cash and cash equivalents of $23.8 million as of December 31, 2022, combined with proceeds from a $20.3 million gross fundraise completed in February 2023, will enable us to fund our current operating plan for at least the next 12 months. Such expectation is based, in part, on the achievement of certain assumed revenue; however, there is no guarantee we will achieve this amount of revenue during the time period we assume. Management assesses that various operating cost mitigation options are available to the Company if needed. We have based this estimate on assumptions that may prove to be wrong, and we could use our available capital resources sooner than we currently expect.

**Cash Flows**

Net cash used in operating activities

During the six months ended December 31, 2022, net cash used in operating activities was $15.4 million and was primarily attributable to our $22.4 million net loss including a $3.0 million net change in our operating assets and liabilities and $4.0 million in noncash charges. The change in our operating assets and liabilities was primarily attributable to a $2.5 million increase in accounts payable and accrued expenses and other current liabilities and a $0.5 million increase in prepaid expenses and other current assets. Noncash charges were primarily related to $1.6 million in share-based compensation, $1.2 million fair value adjustment of our VericiDx securities, $0.7 million fair value adjustment of our convertible debt, a $0.3 million unrealized foreign exchange loss and $0.2 million of depreciation and amortization.

During the six months ended December 31, 2021, net cash used in operating activities was $24.7 million and was primarily attributable to our $25.4 million net loss including $2.3 million in noncash charges and a $1.6 million net change in our operating assets and liabilities. The change in our operating assets and liabilities was primarily attributable to a $2.5 million increase in prepaid expenses and other current assets offset by a $1.4 million decrease in accounts payable and accrued expenses. Noncash charges were primarily related to $1.9 million in share-based compensation and the $2.0 million fair value adjustment of our VericiDx securities, offset by a $1.9 million unrealized foreign exchange gain.

Net cash used in investing activities

During the six months ended December 31, 2022, net cash used in investing activities was $0.1 million, attributable to the purchase of long term assets.

During the six months ended December 31, 2021, net cash used in investing activities was $0.4 million, primarily attributable to $0.3 million for purchases of lab and office equipment and $0.1 million in software development costs.

Net cash used in financing activities

During the six months ended December 31, 2022, net cash used in financing activities was $0.9 million and was primarily attributable to $1.0 million in cash used to pay down the principal of the convertible debt, offset by $0.1 million in proceeds from the issuance of ordinary shares under our employee stock purchase program.

During the six months ended December 31, 2021, net cash provided by financing activities was $0.3 million and was primarily attributable to $0.1 million in proceeds from the issuance of ordinary shares under our employee stock purchase program as well as $0.2 million in proceeds from the exercise of stock options.

**Cash and Cash Equivalents**

We had cash and cash equivalents of $23.8 million as of December 31, 2022, which decreased from $41.3 million as of June 30, 2022 due to normal operations as we continue to commercialize KidneyIntelX and grow our business.

**Critical accounting policies and significant judgments and estimates**

Our management's discussion and analysis of our financial condition and results of operations is based on our unaudited condensed consolidated financial statements, which we have prepared in accordance with generally accepted accounting principles in the United States, "U.S. GAAP". The preparation of our unaudited condensed consolidated financial statements and related disclosures requires us to make estimates and judgments that affect the reported amounts of assets, liabilities, costs and expenses, and the disclosure of contingent assets and liabilities in our unaudited condensed consolidated financial statements. We base our estimates on historical experience, known trends and events and various other factors that we believe are 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. We evaluate our estimates and assumptions on an ongoing basis. Our actual results may differ from these estimates under different assumptions or conditions.

There have been no material changes to our critical accounting policies from those described in "Management's Discussion and Analysis of Financial Condition and Results of Operations" included in our Annual Report.

**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 are in the process of evaluating 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 may 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) the last day of the fiscal year (1) following the fifth anniversary of the completion of our U.S. IPO, (2) in which we have total annual gross revenues of at least $1.235 billion or (3) 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 (b) the date on which we have issued more than $1.0 billion in non-convertible debt during the prior three-year period.

**Renalytix plc** 

**Notes to unaudited interim COndensed consolidated financial statements** 

**1. Business and risks** 

Renalytix and its wholly-owned subsidiaries, Renalytix AI, Inc. and Renalytix AI Limited, (collectively, "Renalytix", or the "Company") 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 has successfully completed the first stage of a statement of work with AstraZeneca Pharmaceuticals LP ("AstraZeneca") to conduct a feasibility study to determine the impact of the use of the Company's KidneyIntelX platform to optimize utilization of various CKD agents. Further, in December 2020 the Company entered into a master service agreement with AstraZeneca for future services of this nature. As a result of the initial success with AstraZeneca the Company plans to pursue further 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.

In August 2020, the Company created a wholly-owned subsidiary of Renalytix AI plc, Renalytix AI Limited ("Limited") to facilitate operations in Ireland.

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.

**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 $155.1 million as of December 31, 2022. 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. Management believes its cash and cash equivalents of $23.8 million as of December 31, 2022, combined with proceeds from a $20.3 million gross fundraise completed in February 2023, are sufficient to fund the projected operations for at least the next twelve months from the issuance date of these financial statements. Such expectation is based, in part, on the achievement of a certain volume of assumed revenue; however, there is no guarantee we will achieve this amount of revenue during the time period we assume. Management assessed various additional operating cost reduction options that are available to the Company and would be implemented, if assumed levels of revenue are not achieved and additional funding is not obtained.

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 plans to seek 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 could be required to delay, curtail or discontinue research and development programs, product portfolio expansion or future commercialization efforts, which could adversely affect its business prospect.

**3. Basis of presentation and summary of significant accounting policies** 

The accompanying unaudited interim condensed consolidated financial statements have been prepared in conformity with generally accepted accounting principles in the United States ("U.S. GAAP"). 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 accompanying unaudited interim condensed consolidated financial statements include all normal and recurring adjustments (which consist primarily of accruals and estimates that impact the financial statements) considered necessary to present fairly the Company's financial position as of December 31, 2022 and its results of operations for the three and six months ended December 31, 2022 and 2021 and cash flows for the six months ended December 31, 2022 and 2021. Operating results for the three and six months ended December 31, 2022, are not necessarily indicative of the results that may be expected for the year ending June 30, 2023. The unaudited interim condensed consolidated financial statements, presented herein, do not contain the required disclosures under U.S. GAAP for annual financial statements. The accompanying unaudited interim condensed consolidated financial statements should be read in conjunction with the annual audited consolidated financial statements and related notes as of and for the year ended June 30, 2022.

**Principles of consolidation**

The unaudited interim condensed consolidated financial statements include the accounts of Renalytix plc, and its wholly-owned subsidiaries, Renalytix AI, Inc. and Renalytix AI Limited. 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, determining useful lives of property and equipment and capitalized software, the assessment of noncontrolling interest and equity method investments.

**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 income (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 receivable are derived from revenue earned from customers located in the U.S. For the six months ended December 31, 2022 and 2021 approximately 94% and 99%, respectively, of all receivables were outstanding from two customers, Mount Sinai and AstraZeneca. The remaining 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/or other factors to assess the customers' ability to pay.

**Fair value of financial instruments** 

At December 31, 2022 and June 30, 2022, the Company's financial instruments included accounts receivable, prepaid expenses and other current assets, accounts payable and 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 December 31, 2022, the Company had a cash balance of $23.8 million. As of June 30, 2022, the Company had a cash balance of $41.3 million.

**Accounts receivable**

Accounts receivable are recorded at the invoice amount and are non-interest bearing. The Company considers receivables past due based on the contractual payment terms. The Company reserves specific receivables if collectability is no longer reasonably assured. Estimates for allowances for doubtful accounts are determined based on existing contractual obligations, historical payment patterns, and individual customer circumstances. No reserves have been recorded as of December 31, 2022 or June 30, 2022.

**Property and equipment** 

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.

**Leases**

Effective July 1, 2022, the Company adopted Accounting Standards Codification ("ASC"), Topic 842, Leases ("ASC 842"), using the required modified retrospective approach and utilizing the effective date as its date of initial application.

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. Most leases with a term greater than one year are recognized on the balance sheet as right-of-use assets, lease liabilities and, if applicable, long-term lease liabilities. The Company has elected not to recognize on the balance sheet, leases with terms of one year or less. Operating lease liabilities and their corresponding right-of-use assets are recorded based on the present value of lease payments over the expected remaining lease term. However, certain adjustments to the right-of-use asset may be required for items such as incentives received, initial direct costs, or prepayments. The interest rate implicit in lease contracts is typically not readily determinable. As a result, the Company utilizes its incremental borrowing rates, which are the rates incurred to borrow on a collateralized basis over a similar term an amount equal to the lease payments in a similar economic environment.

In accordance with the guidance in ASC 842, components of a lease should be split into three categories: lease components (e.g., land, building, etc.), non-lease components (e.g., common area maintenance, consumables, etc.), and non-components (e.g., property taxes, insurance, etc.). Then the fixed and in-substance fixed contract consideration (including any related to non-components) must be allocated based on the respective relative fair values to the lease components and non-lease components.

Upon adoption, the Company did 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.

**Performance of contract liability to affiliate**

In May 2020, the Company and the Icahn School of Medicine at Mount Sinai entered into an operating agreement ("Kantaro Operating Agreement") to form a joint venture, Kantaro Biosciences LLC ("Kantaro"), for the purpose of developing and commercializing laboratory tests for the detection of antibodies against SARS-CoV-2 originally developed by Mount Sinai. Kantaro has partnered with Bio-Techne Corporation to develop and launch the new test which is designed for use in any authorized clinical testing laboratory without the need for proprietary equipment. During the three and six months ended December 31, 2022, the Company recognized $0.01 million and $0.02 million, respectively, related to the performance of the contract liability with Kantaro. During the three and six months ended December 31, 2021, the Company recognized $0.1 million and $0.1 million, respectively, related to the performance of the contract liability with Kantaro. This represents the allocation of costs for performing services on behalf of Kantaro. On December 31, 2022, the members and managers of Kantaro decided that it was in the best interest of Kantaro to wind up the Kantaro business. As part of the termination agreement, the members agreed that Renalytix has no further liability to perform services on behalf of Kantaro.

**Equity method investments** 

The Company accounts for equity investments where it owns a non-controlling interest, but has the ability to exercise significant influence, under the equity method of accounting. Under the equity method of accounting, the original cost of the investment is adjusted for the Company's share of equity in the earnings of the equity investee and reduced by dividends and distributions of capital received, unless the fair value option is elected, in which case the investment balance is marked to fair value each reporting period and the impact of changes in fair value of the equity investment are reported in earnings.

Kantaro Biosciences LLC

As the Company can exert significant influence over, but does not control, Kantaro's operations through voting rights or representation on Kantaro's board of directors, the Company accounts for this investment using the equity method of accounting. The Company records its share in Kantaro's earnings and losses in the condensed consolidated statement of operations. The Company assesses its investment for other-than-temporary impairment when events or changes in circumstances indicate that the carrying amount of the investment might not be recoverable and recognize an impairment loss to adjust the investment to its then-current fair value. The Company owned 25% of the membership equity units in Kantaro at December 31, 2022 and June 30, 2022. On December 31, 2022, the members and managers of Kantaro decided that it was in the best interest of Kantaro to wind up the business and unanimously signed a termination agreement. As part of the termination agreement, the members agreed to wind up Kantaro's business and dissolve it promptly after the effective date of the termination agreement.

**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 3). 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 to be 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. Technological feasibility is established upon the completion of a working model that has been validated.

**Revenue recognition**

The Company accounts for revenue under ASC 606 – Revenue from Contracts with Customers ("ASC 606"). Pursuant to ASC 606, 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 present right to payment 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 costs and lab consumables 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 and other studies for KidneyIntelX to determine clinical value and performance in different CKD populations. 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. Restricted stock units are measured at the fair value of our American Depository Shares on the date of grant. 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 condensed 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.

------

**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 includes 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 quarter ended December 31, 2022, the diluted and basic net loss per share calculation excluded 4,977,699 shares related to stock options, as the exercise price of these options was greater than their market value. Therefore, the weighted average number of shares used to calculate both basic and diluted net loss per share are the same.

**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 current guidance as this will require immediate recognition of estimated credit losses expected to occur over the remaining life of many financial assets. The new guidance will be effective for the Company on July 1, 2023. The Company is currently evaluating the impact of adopting this guidance to its 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 ("ASU2020-06"). 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 ASU 2020-06 and it is not expected to have a material impact on the consolidated financial statements.

**4. Revenue**

Testing services revenue

Testing services revenue is generated from the KidneyIntelX platform, which provides analytical services to customers. Each individual test is a performance obligation that is satisfied at a point in time upon completion of the testing process (when results are reported) which is when control passes to the customer and revenue is recognized. During the three and six months ended December 31, 2022, the Company recognized $1.0 million and $2.0 million, respectively of testing services revenue. Sales tax and other similar taxes are excluded from revenues. During the three and six months ended December 31, 2021, the Company recognized $0.7 million and $1.1 million, respectively of testing services revenue.

------

Pharmaceutical services revenue

Pharmaceutical services revenue is generated from the provision of analytical services to customers. Contracts with customers generally include an initial upfront payment and additional payments upon achieving performance milestones. The Company uses present right to payment and customer acceptance as indicators to determine the transfer of control to the customer which may occur at a point in time or over time depending on the individual contract terms. Sales tax and other similar taxes are excluded from revenues.

During the three and six months ended December 31, 2022, the Company recognized $0.2 million and $0.2 million, respectively, of pharmaceutical services revenue where performance obligations are satisfied over time. During the three and six months ended December 31, 2021 Company recognized $0.2 million and $0.2 million, respectively, of pharmaceutical services revenue where performance obligations are satisfied over time.

Professional services revenue

Professional services revenue consists of services related to the creation of a branded care navigation portal/pathway for use with KidneyIntelX. Revenue is recognized when control of the promised services is transferred to customers and the performance obligation is fulfilled in an amount that reflects the consideration that the Company expects to be entitled in exchange for those services.

The Company did not recognize any professional services revenue during the three and six months ended December 31, 2022 or during the three and six months ended December 31, 2021.

Deferred revenue

Deferred revenue represents the allocated transaction price to the material right which will be recognized as revenue when the renewal options are exercised which is expected to occur over the next few months.

The following table summarizes the changes in deferred revenue:

---

**5. Fair value measurements and the fair value option**

Assets and liabilities recorded at fair value on a recurring basis in the condensed 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:

---

------

As further described in Note 8, in April 2022 the Company issued convertible promissory notes (the "Notes") to various investors. 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.

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 condensed 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.

**6. Property and equipment**

Property and equipment consists of (in thousands):

Depreciation expense was $0.1 million and $0.2 million for the three and six months ended December 31, 2022, respectively. Depreciation expense was $0.1 million and $0.2 million for the three and six months ended December 31, 2021, respectively.

As of December 31, 2022 there was $1.1 million of unamortized capitalized software development costs. Amortization expense related to capitalized software development costs was $0.1 million and $0.1 million, respectively for the three and six months ended December 31, 2022 and $0.02 million and $0.1 million, respectively for the three and six months ended December 31, 2021.

As of December 31, 2022, the expected amortization expense for software for the next five years and thereafter is as follows:

**8. Convertible Notes** 

In April 2022, the Company issued amortizing senior convertible bonds with a principal amount $21.2 million in amortizing senior convertible bonds due in April 2027 (the "Bonds"). 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 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 Convertible Bonds of $8.70 has been set at a 20 per cent. premium to the Reference ADS Price. The Conversion Price may reset down at 12, 24 and 36 months, depending on share price performance and save in limited circumstances, the Bonds have a hard floor in the conversion price of $7.25. 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.

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 per cent. of the nominal amount In July 2022, 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. In October 2022, the company made an interest payment of $0.3 million. As of December 31, 2022, $20.1 million of principal was outstanding.

On issuance, the Company elected to account for the Bonds at fair value in accordance with ASC 815, Derivatives and Hedging, with qualifying changes in fair value being recognized through the statements of operations until the Bonds are settled. Changes in fair value related to instrument-specific credit risk are recognized through comprehensive loss until the Bonds are settled. 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. Significant assumptions used in the fair value analysis include the volatility rate, risk-free rate, dividend yield and risky yield. As of December 31, 2022, the fair value of the Bonds was determined to be $11.9 million. During the three and six months ended December 31, 2022, the Company recognized a change in fair value of the Notes related to the instrument-specific credit risk of $0.9 million and $0.5 million, respectively, in the statement of comprehensive loss. The Company recognized an increase in fair value related to non-instrument specific credit risk of $0.4 million during the three months ended December 31, 2022 and an increase in fair value related to non-instrument specific credit risk of $0.7 million in the consolidated statement of operations during the six months ended December 31, 2022.

**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. The Company expenses the variable lease payments in the period in which it incurs the obligation to pay such variable amounts and will be included in variable lease costs in the leases footnote disclosure. These variable lease payments are not included in the Company's calculation of its right-of-use assets or lease liabilities.

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 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 Company leased office space in New York City, NY under an initial month-to-month term, the term of which commenced in June 2018. The lease did not have termination or formal renewal options however the Company can renew their spaces 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 estimated the incremental borrowing rate for each lease by considering average interest rates on commercial real estate loans during 2022 which range from 2.2%, for established borrowers with excellent credit ratings, to 18.0%, for borrowers early in the business' life cycle and with lower credit ratings. As the Company is an early-stage biotech company with minimal revenues, the Company 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.

**13. Share-based compensation**

**Equity Incentive Plans**

In November 2018, Company established the Renalytix plc Share Option Plan (the "Plan") and a U.S. Sub-Plan and Non-Employee Sub-Plan. The Plans provide for the Company to grant options, restricted share awards and other share-based awards to employees, directors and consultants of the Company. As of December 31, 2022, there were 10,739,229 shares available for future issuance under the Plans.

The Plans are 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.

The options granted as of December 31, 2022 consist of 2,299,799 options which vest equally over twelve quarters following the grant date, 962,600 options which vest 25% on the one year anniversary and equally over twelve quarters following the one year anniversary and 500,000 which vest 1/12th immediately and the remainder equally over the remaining eleven quarters, 475,300 which vest 25% on the one year anniversary, 50% on 2nd anniversary and 25% on the third anniversary and 40,000 which vest in eight equal quarterly instalments commencing on the Vesting Commencement date.

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 condensed consolidated statements of operations for the three and six months ended December 31, 2022 and 2021 (in thousands):

| | | | | |
|:---|:---|:---|:---|:---|

| Cost of revenue | 2 |  | 2 |  |
|  | $815 | $913 | $1578 | $993 |

---

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 December 31, 2022 and 2021 were determined using the methods and assumptions discussed below.

oThe 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.

oThe expected volatility is based on historical volatility of the publicly-traded common stock of a peer group of companies.

oThe 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.

oThe 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 three months ended December 31, 2022 and 2021, 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:

---

| | | |
|:---|:---|:---|
|  | **Six Months Ended December 31,** | **Six Months Ended December 31,** |
|  | **2022** | **2021** |

| Expected volatility | 66.9% | 65.8% |
| Risk-free rate | 3.2% | 1.28% |
| Dividend yield | —% | —% |

---

The weighted average fair value of the options granted during the six months ended December 31, 2022 was $1.16. The weighted average fair value of the options granted during the six months ended December 31, 2021 was $7.10 per share.

The following table summarizes the stock option granted to employees and non-employees for the six months ended December 31, 2022:

As of December 31, 2022, there was $3.8 million in unrecognized compensation cost related to unvested options that will be recognized as expense over a weighted average period of 2.15 years. The aggregate intrinsic value of options outstanding and options exercisable at December 31, 2022 and 2021 was $0.0 million and $18.0 million, respectively.

**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 shares of the Company's common stock. The number of shares of the Company's common stock 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 shares of the Company's common stock 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 common stock 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 common stock at 85% of the lower of the fair market value of the Company's common stock 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 common stock for each calendar year in which such rights are outstanding. During the six months ended December 31, 2022, 131,412 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 common stock 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 $0.02 million and $0.05 million three and six months ended December 31, 2022, respectively, and $0.02 million and $0.05 million during the three and six months ended December 31, 2021, respectively, related to the ESPP.

**Icahn School of Medicine at Mount Sinai**

In May 2018, the Company secured its cornerstone license agreement with the Icahn School of Medicine at Mount Sinai ("ISMMS") for research and clinical study work and intended commercialization by the Company (see Note 11). As part of the collaboration, ISMMS became a shareholder in the Company and has subsequently made equity investments both in the Company's IPO on AIM in November 2018, the subsequent sale of ordinary shares in July 2019 and the Company's IPO on Nasdaq in July 2020. As of December 31, 2022, amounts due to ISMMS totaled $4.0 million and are included within accrued expenses and other current liabilities and accounts payable on the balance sheet. During the three and six months ended December 31, 2022, the Company incurred expenses of $0.0 million and $1.4 million, respectively, which are included in research and development expenses in the condensed consolidated statement of operations.

**Kantaro Biosciences LLC**

In connection with the formation of Kantaro, the Company entered into a five-year Advisory Services Agreement ("Advisory Agreement") pursuant to which the Company has agreed to provide certain advisory services to Kantaro. Pursuant to the Kantaro Operating Agreement, Kantaro issued 750 Class A Units to Mount Sinai in exchange for Mount Sinai granting licenses to Kantaro under certain intellectual property rights of Mount Sinai and 250 Class A Units to the Company as the sole consideration for the services to be rendered by the Company under the Advisory Agreement. A portion of the Company's units are subject to forfeiture if, prior to December 31, 2021, Kantaro terminates the Advisory Agreement as a result of an uncured material breach of the Advisory Agreement or in the event the Company is acquired by a hospital or health system that serves all or any portion of the service areas served by Mount Sinai. The Company determined the fair value of the services to be provided under the Advisory Agreement was $2.0 million and the fair value of the Class A units received from Kantaro was $2.0 million. Fair value was determined using discounted cash flows which is a Level 3 measurement in the fair value hierarchy. The method requires several judgments and assumptions which include discount rates and future cash flows, among others. As a result of the prior year impairment charge discussed in Note 3, the carrying value of the Kantaro investment was written down to zero.

------

A contributing factor to the impairment consideration for Kantaro was lower forecasted sales volume and consequently, a lower time commitment from Renalytix employees. Based on these circumstances, the Company adjusted the liability to perform services to Kantaro under the Advisory Agreement during the year ended June 30, 2021. On December 31, 2022, the members and managers of Kantaro decided that it was in the best interest of Kantaro to wind up the business and unanimously signed a termination agreement. As part of the termination agreement, the members agreed to wind up Kantaro's business and dissolve it reasonably promptly after the effective date of the termination agreement. As of December 31, 2022, the total liability associated with the services was $0.0, as the termination agreement relieved Renalytix of its obligation to provide services to Kantaro.

In addition to the equity granted at formation, in May 2020 the Company and Mount Sinai each committed to making a loan to Kantaro. Mount Sinai committed to lend an initial amount of $0.3 million and an additional $0.5 million thereafter. The Company committed to lend an initial amount of $0.08 million and an additional $0.17 million thereafter. Each loan bears interest at a per year rate equal to 0.25%, compounded monthly, until repaid, and is repayable from the first amounts that would otherwise constitute cash available for distribution to the members of Kantaro (provided that each loan repayment will be made, 75% to Mount Sinai and 25% to the Company based on each investor's proportionate ownership). The Company loaned Kantaro $0.25 million and initially recorded a note receivable. The loan had a carrying value of approximately $0.075 million at December 31, 2022 and June 30, 2022.

**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 December 31, 2022 and 2021 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 common stock outstanding, as they would be anti-dilutive:
