ENZO BIOCHEM, INC.
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
As of April 30, 2021
(Unaudited)
(Dollars in thousands, except share data)

Note 1 – Basis of Presentation

The accompanying consolidated financial statements include the accounts of Enzo Biochem, Inc. and its wholly-owned subsidiaries, Enzo Life Sciences, Enzo Clinical Labs, Enzo Therapeutics, Enzo Realty LLC and Enzo Realty II LLC, collectively or with one or more of its subsidiaries referred to as the “Company” or “Companies”. The Company has three reportable segments: Clinical Services, Products, and Therapeutics. The consolidated balance sheet as of April 30, 2021, the consolidated statements of operations, comprehensive income (loss) and stockholders’ equity for the three and nine months ended April 30, 2021, and the consolidated statements of cash flows for the nine months ended April 30, 2021 (the “interim statements”) are unaudited. In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position and operating results for the interim periods have been made. Certain information and footnote disclosure, normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States, have been condensed or omitted. The interim statements should be read in conjunction with the consolidated financial statements for the fiscal year ended July 31, 2020 and notes thereto contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission. The consolidated balance sheet at July 31, 2020 has been derived from the audited financial statements at that date. The results of operations for the nine months ended April 30, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending July 31, 2021.

While the rate of transmission of COVID-19 is declining in the US and Europe, it continues to spread in other parts of the world and negatively impact the world economy. Federal, state and local governmental policies and initiatives designed to reduce the transmission of COVID-19 have resulted in, among other things, a significant reduction in physician office visits, the cancellation of elective medical procedures, customers of our products remaining closed or continuing to severely curtail their operations (voluntarily or in response to government orders), and the continuation of work-from-home or shelter-in-place policies. The COVID-19 impact on the Company’s operations is consistent with the overall industry and publicly issued statements from competitors, partners, and vendors.

The extent to which our businesses may continue to be affected by the COVID-19 pandemic will largely depend on both current and future developments, including its duration, the emergence and spread of variants, its treatment with authorized vaccines and vaccines in various stages of development and federal approval, work and travel advisories and restrictions, and the timing of their easing, all of which are highly uncertain and cannot be reasonably predicted at this time. Global supply chain issues due to the pandemic continue to hamper both the manufacturing of products within the life science division as well as testing capabilities in the clinical laboratory.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“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 financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

COVID 19

The extent to which the COVID-19 pandemic impacts the Company’s business and financial results will depend on numerous evolving factors including, but not limited to: the magnitude and duration of the COVID-19 pandemic, the extent to which it will impact worldwide macroeconomic conditions including, but not limited to, employment rates and health insurance coverage, the speed of the anticipated recovery, and governmental and business reactions to the pandemic. The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 as of April 30, 2021 and through the date of this report. The accounting matters assessed included, but were not limited to, the Company’s patient self-pay revenue concessions and credit losses in the Clinical Services segment, accounts receivable, inventories and the carrying value of goodwill and other long-lived assets. The Company’s future assessment of the magnitude and duration of COVID-19, as well as other factors, could result in additional material impacts to the Company’s consolidated financial statements in future reporting periods. We fully expect COVID-19 volume to decline in the quarters ahead as the percentage of Americans who are vaccinated increases.

Effect of New Accounting Pronouncements

Pronouncements Issued but Not Yet Adopted

In June 2016, FASB issued ASU No. 2016-13 Financial Instruments – Credit Losses (Topic 326). This standard, as amended, changes the impairment model for most financial instruments, including trade receivables, from an incurred loss method to a new forward-looking approach, based on expected losses. The estimate of expected credit losses will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. Adoption of this standard is required for our annual and interim periods beginning August 1, 2023 as long as we continue to qualify as a smaller reporting company at the end of fiscal 2022, and must be adopted using a modified retrospective transition approach. We are currently assessing the impact of the adoption of this standard on our results of operations, financial position and cash flows.

In December 2019, the FASB issued ASU No. 2019-12 Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. The amendments in the ASU simplify the accounting for income taxes by removing certain exceptions to the general principles of Topic 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this ASU are required for our annual and interim periods beginning August 1, 2021. The adoption of the amendments in this ASU is not expected to have a material impact on our consolidated results of operations, financial position or cash flows

We reviewed all other recently issued accounting pronouncements and have concluded they are not applicable or not expected to be significant to the accounting for our operations.

Concentration Risk

Other than the Medicare program, two providers whose programs are included in the “Third-party payers” and “Health Maintenance Organizations” (“HMO’s”) categories represent approximately 36% and 35% of Clinical Services net revenue for the three and nine month periods ended April 30, 2021. Other than the Medicare program, one provider whose programs are included in those categories represents approximately 21% of Clinical Services net revenue for both the three and nine month periods ended April 30, 2020. As of April 30, 2021, the Medicare program represents 15%, a provider in the third party category represents 13%, and a government payer in the patient self-pay category represents 10% of Clinical Services net receivables.

Income Taxes

The Company accounts for income taxes under the liability method of accounting for income taxes. Under the liability method, 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. The liability method requires that any tax benefits recognized for net operating loss carry forwards and other items be reduced by a valuation allowance where it is not more likely than not the benefits will be realized in the foreseeable future. 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. Under the liability method, 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. It is the Company’s policy to provide for uncertain tax positions, if any, and the related interest and penalties based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. To the extent the Company prevails in matters for which a liability for an unrecognized tax benefit is established or is required to pay amounts in excess of the liability, the Company’s effective tax rate in a given financial statement period may be affected.

Due to our tax net operating loss carryforwards, we do not provide for an income tax provision on pre-tax income in the fiscal 2021 periods. We maintain a full valuation allowance on all tax assets and, as a consequence, do not provide any tax benefit for the fiscal 2020 period losses.

8

Fair Value Measurements

The Company determines fair value measurements used in its consolidated financial statements based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy. The basis for fair value measurements for each level within the hierarchy is described below with Level 1 having the highest priority and Level 3 having the lowest.

Level 1 Quoted prices in active markets for identical assets or liabilities.

Level 2 Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.

Level 3 Valuations derived from valuation techniques in which one or more significant inputs are unobservable.

Marketable securities

The Company limits its credit risk associated with investments by investing in a mutual fund and an exchange traded fund (ETF) which hold highly rated corporate bonds, asset backed securities, municipal bonds, mortgage obligations and government obligations. These investments are classified as trading securities and are Level 1 fair value investments. As of April 30, 2021, the fair value of these investments was $29,932 and the cost basis was $30,023. We recognized unrealized losses of $91 for the three and nine months ended April 30, 2021.

Note 2 – Net income (loss) per share

Basic net income (loss) per share represents net income (loss) divided by the weighted average number of common shares outstanding during the period. For the three and nine months ended April 30, 2021, approximately 397,000 and 104,000 weighted average stock options and performance stock units respectively were included in the calculation of diluted weighted average shares outstanding. As a result of the net loss for the three and nine month periods ended April 30, 2020, diluted weighted average shares outstanding are the same as basic weighted average shares outstanding, and do not include the potential common shares from stock options and performance stock units because to do so would be antidilutive. For the three and nine months ended April 30, 2020, approximately 40,000 and 56,000 respectively, of potential common shares (“in the money options”) were excluded from the calculation of diluted earnings per share.

For the three and nine months ended April 30, 2021, the effect of approximately 814,000 and 1,686,000 of outstanding “out of the money” options to purchase common shares were excluded from the calculation of diluted net income per share because their effect would be anti-dilutive. For the three and nine months ended April 30, 2020, the effect of approximately 2,201,000 and 1,805,000 of outstanding “out of the money” options to purchase common shares were excluded from the calculation of diluted net income per share because their effect would be anti-dilutive.

Note 3 – Revenue Recognition

Clinical Services Revenue

Service revenues in the Company’s clinical services business accounted for approximately 76% of the Company’s total revenues for the three and nine months ended April 30, 2021 and 58% of the Company’s total revenues for the three and nine months ended April 30, 2020, and are primarily comprised of a high volume of relatively low-dollar transactions. The services business, which provides clinical testing services, satisfies its performance obligation and recognizes revenues upon completion of the testing process for a specific patient and reporting to the ordering physician. The Company may also perform clinical testing services for other laboratories and will recognize revenue from those services when reported to the ordering laboratory. The Company estimates the amount of consideration it expects to receive from customer groups using the portfolio approach. These estimates of the expected consideration include the impact of contractual allowances and price concessions on our customer group portfolios consisting of healthcare insurers, government payers, client payers and patients as described below. Contracts with customers in our laboratory services business do not contain a financing component, based on the typically limited period of time between performance of services and collection of consideration. The transaction price includes variable consideration in the form of the contractual allowance and price concessions as well as the collectability of the transaction based on patient intent and ability to pay. The Company uses the expected value method in estimating the amount of the variability included in the transaction price.

The following are descriptions of our laboratory services business portfolios:

Third party payers and Health Maintenance Organizations (HMO’s)

Reimbursements from third party payers, primarily healthcare insurers and HMO’s are based on negotiated fee-for-service schedules and on capitated payment rates. Revenues consist of amounts billed net of contractual allowances for differences between amounts billed and the estimated consideration the Company expects to receive from such payers, which considers historical collection and denial experience and the terms of the Company’s contractual arrangements. Adjustments to the allowances, based on actual receipts from the third-party payers, are recorded upon settlement.

Collection of the consideration the Company expects to receive is normally a function of providing complete and correct billing information to these third party payers within the various filing deadlines, and typically occurs within 30 to 90 days of billing. Provided the Company has billed healthcare insurers accurately with complete information prior to the established filing deadline, there has historically been little to no collection risk. If there has been a delay in billing, the Company determines if the amounts in question will likely go past the filing deadline, and if so, will reserve accordingly for the billing.

Third-party payers, including government programs, may decide to deny payment or recoup payments for testing that they contend was improperly billed or not medically necessary, against their coverage determinations, or for which they believe they have otherwise overpaid (including as a result of their own error), and we may be required to refund payments already received.

Our revenues may be subject to adjustment as a result of these factors among others, including without limitation, differing interpretations of billing and coding guidance and changes by government agencies and payers in interpretations, requirements, and “conditions of participation” in various programs.

Government Payer - Medicare

Reimbursements from Medicare are based on fee-for-service schedules set by Medicare, which is funded by the government. Revenues consist of amounts billed net of contractual allowances for differences between amounts billed and the estimated consideration the Company expects to receive from Medicare, which considers historical collection and denial experience and other factors. Adjustments to the allowances, based on actual receipts from the government payers, are recorded upon settlement.

Collection of consideration the Company expects to receive is normally a function of providing the complete and correct billing information within the various filing deadlines and typically occurs within 60 days of billing. Provided the Company has billed the government payer accurately with complete information prior to the established filing deadline, there has historically been little to no collection risk. If there has been a delay in billing, the Company determines if the amounts in question will likely go past the filing deadline, and, if so, it will reserve accordingly for the billing.

10

Patient self-pay

Uninsured patients are billed based on established patient fee schedules or fees negotiated with physicians on behalf of their patients. Coinsurance and deductible responsibilities based on fees negotiated with healthcare insurers are also billed to insured patients and included in this portfolio. Collection of billings from patients is subject to credit risk and ability of the patients to pay. Revenues consist of amounts billed net of discounts provided to uninsured patients in accordance with the Company’s policies and implicit price concessions. Implicit price concessions represent differences between amounts billed and the estimated consideration the Company expects to receive from patients, which considers historical collection experience and other factors including current market conditions. Adjustments to the estimated allowances, based on actual receipts from the patients, are recorded upon settlement. Patient responsibility is invoiced and if it reaches 91 days outstanding, the account is sent to a collection agency for further processing. After the account has been with the collection agency for at least 105 days, and is determined to be uncollectable it is written off.

For nine months ended April 30, 2021 and 2020, all of the Company’s clinical services revenues were generated within the United States.

Products Revenue

Products revenues consist of the sale of single-use products used in the identification of genomic information and are recognized at a point in time following the transfer of control of such products to the customer, which generally occurs upon shipment. Payment terms for shipments to end-user and distributor customers may range from 30 to 90 days. Any claims for credit or return of goods may be made generally within 30 days of receipt. Revenues are reduced to reflect estimated credits and returns, although historically these adjustments have not been material. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenue. Amounts billed to customers for shipping and handling are included in revenue, while the related shipping and handling costs are reflected in cost of products.

Products revenue by geography is as follows:

	Three Months Ended April 30				Nine Months Ended April 30

Note 7 – Long term debt

In connection with the purchase of our new facility in November 2018, a wholly-owned subsidiary (the “mortgagor subsidiary”) of the Company entered into a Fee Mortgage and Security Agreement (the “mortgage agreement”) with Citibank, N.A. (the “mortgagee”). The mortgage agreement provides for a loan of $4,500 for a term of 10 years, bears a fixed interest rate of 5.09% per annum and requires monthly mortgage payments of principal and interest of $30. Debt issuance costs of $72 are being amortized over the life of the mortgage agreement. The balance of unamortized debt issuance cost was $55 at April 30, 2021. At April 30, 2021, the balance owed by the subsidiary under the mortgage agreement was approximately $4.2 million. The Company’s obligations under the mortgage agreement are secured by the new facility and by a $750 cash collateral deposit with the mortgagee as additional security. This restricted cash is included in other assets as of April 30, 2021. We assumed from the seller an operating lease for a tenant at the facility which expired on June 30, 2020. Rental income from the assumed lease for the three and nine months ended April 30, 2020 is included in Other income.

The mortgage agreement includes affirmative and negative covenants and events of default, as defined. Events of default include non-payment of principal and interest on debt outstanding, non-performance of covenants, material changes in business, breach of representations, bankruptcy or insolvency, and changes in control. The mortgage includes certain financial and liquidity covenants. As of April 30, 2021, the Company was in compliance with those covenants. The liquidity covenant requires that we own and maintain at all times and throughout the remaining term of the loan at least $25 million of liquid assets, defined as time deposits, money market accounts, commercial paper and obligations issued by the U.S. government or any of its agencies.

In April 2020, our subsidiary in Switzerland received a loan of CHF 0.4 million ($0.4 million, based on the foreign exchange rate as of April 30, 2021) from the Swiss government under the “Corona Krise” emergency loan program in response to the pandemic. This loan is uncollateralized, bears 0% interest, is due in 5 years, and may be repaid at any time. This loan is included in long term debt – net as of April 30, 2021.

The CARES Act expanded the U.S. Small Business Administration’s (SBA) business loan program to create the Paycheck Protection Program (PPP), which provides employers with uncollateralized loans whose primary purpose is to retain or maintain workforce and salaries for a twenty four week period (“covered period”) following receipt of the loan. Currently, PPP loans have a 1% fixed interest rate and are due from two to five years. The primary features of the PPP loan program are to provide funding to companies to cover eligible expenses, and the potential for forgiveness of that portion of the loan spent on payroll and other permitted operating expenses during the covered period, subject to reductions if the borrower fails to maintain or restore employee and salary levels. We applied for the PPP loan based on the eligibility and need requirements established when the program was announced and in April 2020 received $7,000 through Citibank N.A., the Company’s existing lender, pursuant to the PPP.

The PPP Loan matures on April 17, 2022 (the “Maturity Date”), accrues interest at 1% per annum and may be prepaid in whole or in part without penalty. No interest payments are due within the initial six months of the PPP Loan. Interest accrued during the initial six-month period is due and payable, together with the principal, on the Maturity Date. The Company used all proceeds from the PPP Loan to retain employees, maintain payroll and make lease and utility payments to support business continuity throughout the COVID-19 pandemic. All or a portion of the PPP Loan, including interest, could be forgiven by the SBA by applying for forgiveness and providing acceptable documentation that demonstrates the funds were used as required by the terms of forgiveness and in accordance with the SBA’s requirements. Due to complexities with respect to loan forgiveness calculations and government pronouncements with respect to expenditure eligibility, we did not recognize any loan forgiveness as of April 30, 2021 and have classified the loan as other short term debt as the loan matures in less than one year. We expect to earn loan forgiveness on all of the loan proceeds and have accrued no interest. The SBA intends to audit loans in excess of $2.0 million. The SBA also required businesses that received loans in excess of $2 million to complete a loan necessity questionnaire to evaluate the good faith certification made on their PPP applications that economic uncertainty made their loan request necessary to support ongoing operations. In April 2021 we submitted our PPP loan forgiveness application and the loan necessity questionnaire to the SBA through Citibank N.A., our intermediary lending bank. According to the SBA, its review may take up to 90 calendar days from the receipt of the loan forgiveness application and loan necessity questionnaire. No assurance can be given that we will obtain forgiveness of the PPP loan in whole or in part by July 31, 2021.

Note 8 - Leases

The Company follows ASU No. 2016-02 “Leases (Topic 842)”, which requires leases with durations greater than twelve months to be recognized on the balance sheet.

The Company determines if an arrangement is or contains a lease at contract inception. The Company leases buildings, office space, patient service centers, and equipment primarily through operating leases, and equipment through a limited number of finance leases. Generally, a right-of-use asset, representing the right to use the underlying asset during the lease term, and a lease liability, representing the payment obligation arising from the lease, are recognized on the balance sheet at lease commencement based on the present value of the payment obligation. For operating leases, expense is recognized on a straight-line basis over the lease term. For finance leases, interest expense on the lease liability is recognized using the effective interest method and amortization of the right-of-use asset is recognized on a straight-line basis over the shorter of the estimated useful life of the asset or the lease term. Short-term leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term.

The Company primarily uses its incremental borrowing rate in determining the present value of lease payments as the Company’s leases generally do not provide an implicit rate.

The Company has lease agreements with (i) right-of-use asset payments and (ii) non-lease components (i.e. payments related to maintenance fees, utilities, etc.), which have generally been combined and accounted for as a single lease component.

The Company’s leases have remaining terms of less than 1 year to 8 years, some of which include options to extend the leases for up to 5 years. The Company’s lease terms may include renewal options that are reasonably certain to be exercised and termination options that are reasonably certain not to be exercised.

Certain of the Company’s lease agreements include rental payments adjusted periodically for inflation or a market rate which are included in the lease liabilities.

Note 9 – Accrued Liabilities

At April 30, accrued liabilities consist of:

	April 30, 2021		July 31, 2020
Payroll, benefits, and commissions	$	4,273	$	5,227
Professional fees		627		710

Deferred revenue

In order to increase cash flow to providers of services and suppliers impacted by the pandemic, the Centers for Medicare and Medicaid Services (CMS) expanded its Accelerated and Advance Payment Program to a broader group of Medicare providers. We applied for and received a $2,526 payment advance from this program in April 2020. The recoupment by CMS of our advance payment had been scheduled to begin 120 days after the date of receipt, at which time every claim we submit from that point would be automatically offset to repay the advance payment.

In October 2020, the Continuing Appropriations Act, 2021 and Other Extensions Act amended the repayment terms of the Advance Payment Program. The recoupment period was extended and the automatic recoupment begins one year after the date the advance payment was received. CMS began recoupment of our advance in April 2021. During the next 11 months, the recoupment rate will be 25% of claims processed and repayment occurs through an automatic recoupment of our Medicare payments. If the total amount of the advance payment is not recovered within 29 months from the date the advance was received, a demand letter for the outstanding balance will be issued. We expect the entire balance of the payment advance to be recouped by the end of the 11 month period and include the remaining balance in accrued liabilities at April 30, 2021.

Self-Insured Medical Plan

The Company self-funds medical insurance coverage for certain of its U.S. based employees. The risk to the Company is believed to be limited through the use of individual and aggregate stop loss insurance. As of April 30, 2021, the Company has established a reserve of $243, which is included in accrued liabilities, for claims that have been reported but not paid and for claims that have been incurred but not reported. The reserve is based upon the Company’s historical payment trends, claim history and current estimates.

Note 10 – Stockholders’ Equity

Controlled Equity Offering

The Company has a Controlled Equity Offering^SM Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co., as sales agent (“Cantor”). Under the Sales Agreement, the Company may offer and sell, from time to time, through Cantor, shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”). The Company pays Cantor a commission of 3.0% of the aggregate gross proceeds received under the Sale Agreement. The Company is not obligated to make any sales of the Shares under the Sales Agreement. The offering of Shares pursuant to the Sales Agreement will terminate upon the earlier of (a) the sale of all of the Shares subject to the Sales Agreement or (b) the termination of the Sales Agreement by Cantor or the Company, as permitted therein. The initial agreement contemplated the sale of shares of the Company’s common stock having an aggregate offering price of up to $20.0 million. In December 2014, the Sales Agreement was amended in order for the Company to offer and sell additional shares of Common Stock having an aggregate offering price of $20.0 million.

16

In September 2017, the Company filed with the SEC a Form S-3 “shelf” registration and sales agreement prospectus covering the offering, issuance and sale of our Common Stock that may be issued and sold under the existing Sales Agreement in an aggregate amount of up to $19.2 million. A total of $150 million of securities may be sold under this shelf registration, which was declared effective September 2017. The Form S-3 expired in October 2020 but may be refiled at any time at the discretion of the Company.

During the nine months ended April 30, 2021 and 2020, the Company did not sell any shares of Common Stock under the Sales Agreement.

Share-based compensation

In January 2011, the Company’s stockholders approved the adoption of the 2011 Incentive Plan (the “2011 Plan”) for the issuance of equity awards, including, among others, options, restricted stock, restricted stock units and performance stock units for up to 3,000,000 shares of common stock. On January 5, 2018, the Company’s stockholders approved the amendment and restatement of the 2011 Plan (the “Amended and Restated 2011 Plan”) to increase the number of shares of common stock available for grant under the 2011 Plan by 2,000,000 shares of common stock bringing the total number of shares available for grant to 5,000,000 shares of common stock. On October 7, 2020, the Company’s Board of Directors approved the amendment and restatement of the Amended and Restated 2011 Plan, with an effective date of October 7, 2020 and subject to approval by the Company’s stockholders at the 2020 annual meeting of stockholders of the Company. The amendment and restatement of the Amended and Restated 2011 Plan was for purposes of, among other things, (i) increasing the shares of common stock available for grant under the Amended and Restated 2011 Plan by an additional 4,000,000 shares of common stock bringing the total number of shares available for grant to 9,000,000 shares of common stock and (ii) extending the term of the Amended and Restated 2011 Plan until October 7, 2030. In January 2021, the Company’s stockholders approved the amendment and restatement of the Amended and Restated 2011 Plan.

The exercise price of options granted under the Amended and Restated 2011 Plan, as amended and restated, is equal to or greater than fair market value of the common stock on the date of grant. The Amended and Restated 2011 Plan, as amended and restated, will terminate at the earliest of (a) such time as no shares of common stock remain available for issuance under the plan, (b) termination of the plan by the Company’s Board of Directors, or (c) October 7, 2030. Awards outstanding upon expiration of the Amended and Restated 2011 Plan, as amended and restated, will remain in effect until they have been exercised or terminated, or have expired. As of April 30, 2021, there were approximately 4,834,000 shares of common stock available for grant under the Amended and Restated 2011 Plan, as amended and restated.

The amounts of share-based compensation expense recognized in the periods presented are as follows:

	Three months ended April 30,				Nine months ended April 30,
	2021		2020		2021		2020

Stock Option Plans

The following table summarizes stock option activity during the nine month period ended April 30, 2021:

	Options			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term		Aggregate Intrinsic Value (000s)
Outstanding at July 31, 2020		2,636,496		$	4.05
Awarded		543,104		$	2.57
Exercised		(34,667	)		2.80			$
Expired or forfeited		(619,371	)	$	3.40
Outstanding at end of period		2,525,562		$	3.76		2.6 years	$	957
Exercisable at end of period		1,581,326		$			1.6 years	$

As of April 30, 2021, the total future compensation cost related to non-vested options, not yet recognized in the statements of operations, was $916 and the weighted average period over which the remaining expense of these awards is expected to be recognized is approximately sixteen months.

The intrinsic value of in the money stock option awards at the end of the period represents the Company’s closing stock price on the last trading day of the period in excess of the exercise price multiplied by the number of options.

Performance Stock Units

To better align the long-term interest of executives with growing U.S. practices, beginning in fiscal 2018, the Company’s board of directors approved long-term incentive awards in the form of performance-based stock units (“Performance Stock Units” or “PSUs”) in addition to time based stock options. The PSUs earned will be determined over a three fiscal year performance period. The primary performance metrics will be revenue and Adjusted EBITDA growth. Payouts based on revenue and adjusted EBITDA goals will be modified based on Total Shareholder Return (“TSR”) performance relative to Enzo’s peer group.

During the fiscal years ended 2020, 2019 and 2018, the Company’s board of directors approved the award of PSUs to its executive officers, whose established grant dates are in the table below. These awards provide for the grant of shares of our common stock at the end of a three–year period based on the achievement of average revenue growth and adjusted EBITDA growth over that period.

During the nine months ended April 30, 2021, one former executive forfeited a total of 6,000 PSUs. During the nine months ended April 30, 2020, one former executive forfeited a total of 14,500 PSUs. During both the three and nine months ended April 30, 2021 and 2020, the Company recorded $162 and $0, respectively as compensation expense for the outstanding PSU’s.

Note 11 – Segment reporting

The Company has three reportable segments: Products, Clinical Services and Therapeutics. The Company’s Products segment develops, manufactures, and markets products to research and pharmaceutical customers. The Clinical Services segment provides diagnostic services to the health care community. The Company’s Therapeutics segment conducts research and development activities for therapeutic drug candidates. The Company evaluates segment performance based on segment income (loss) before taxes. Costs excluded from segment income (loss) before taxes and reported as “Other” consist of corporate general and administrative costs which are not allocable to the three reportable segments. All intersegment activities are eliminated.

Legal and related expenses incurred to defend the Company’s intellectual property, which may result in settlements recognized in another segment and other general corporate matters are considered a component of the Other segment. Legal and related expenses specific to other segments’ activities are allocated to those segments.

Legal settlements, net, represent activities for which royalties would have been received in the Company’s Products segment. Management of the Company assesses assets on a consolidated basis only and therefore, assets by reportable segment have not been included in the reportable segments below. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies.

The following financial information represents the operating results of the reportable segments of the Company:

Note 12 Contingencies

The Company has brought cases in the United States District Court for the District of Delaware (“the Court”), alleging patent infringement against various companies. In 2017, the Court ruled that the asserted claims of the ‘180 and ‘405 Patents are invalid for nonenablement in cases involving Abbott, Becton Dickinson, Gen-Probe, Hologic, and Roche. That ruling was affirmed by the United States Court of Appeals for the Federal Circuit (“Federal Circuit”) in June 2019. Enzo subsequently filed a petition for certiorari regarding the invalidity ruling for the ‘180 and ‘405 Patents in February 2020; the Supreme Court denied Enzo’s petition on March 30, 2020. There are currently two cases that were originally brought by the Company in the Court. In those two cases, Enzo alleges patent infringement against Becton Dickinson Defendants and Roche Defendants, respectively. The claims in those cases involve the ‘197 Patent. Both cases are stayed.

In separate inter partes review proceedings before the U.S. Patent and Trademark Office involving, among others, Becton Dickinson, certain claims of the ‘197 Patent were found unpatentable as anticipated or obvious and cancelled by the Patent Trial and Appeals Board (“Board”). Enzo appealed that decision to the Federal Circuit. On August 16, 2019, the Federal Circuit affirmed the Board’s decision, finding that each of the challenged claims is unpatentable. The Company filed a petition for rehearing and rehearing en banc on October 30, 2019, which the Federal Circuit denied on December 4, 2019. The Company filed a petition for certiorari with the Supreme Court on March 3, 2020, which was denied.

In April 2019, the Company entered into an agreement with Hologic and Grifols, resolving litigation resulting from four cases originally brought by the Company in the Court. As a result, Enzo dismissed (1) a stayed patent litigation regarding the ‘180 and ‘197 Patent against Hologic in the Court; (2) the Consolidated Appeals against Gen-Probe and Hologic resulting from two cases filed in the Court, and (3) the Company’s appeal in the litigation involving the ‘581 Patent that involved both Hologic and Grifols. As a result of the agreement with Hologic, Hologic withdrew from Enzo’s Federal Circuit appeal of the Board’s adverse rulings in the inter partes review proceedings regarding the ‘197 Patent filed by Hologic and joined by Becton Dickinson mentioned above.

On February 5, 2020, Harbert Discovery Fund, LP and Harbert Discovery Co-Investment Fund I, LP (“Plaintiffs”) brought an action in the United States District Court for the Southern District of New York against the Company and five of its present or former Directors, Dr. Elazar Rabbani, Barry W. Weiner, Dr. Bruce A. Hanna, Dov Perlysky and Rebecca Fischer. On March 26, 2020, Plaintiffs filed an amended complaint against the same defendants. Count I asserted the Company violated Section 14(a) of the Securities and Exchange Act of 1934 and Rule 14a-9 thereunder by disseminating proxy materials that made two purportedly false statements: (a) a “January 28, 2020 Enzo press release [that purportedly] falsely stated that the Annual Meeting would be ‘delayed’ by action of the Board to February 25, 2020 when, in fact, the Annual Meeting would convene as planned on January 31, 2020”, and (b) a “January 31 Enzo Proxy [that purportedly] falsely stated that the Proposed By-Law Amendment [to Article II, Section 9] would be approved if it received…a majority of the votes….rather than the required Supermajority Vote as provided for in the Charter. “Count II asserted a claim against the individual defendants under Section 20(a) of the Exchange Act premised on Enzo’s purported violation of Section 14(a) and Rule 14a-9. Count III asserted the individual defendants breached their fiduciary duty, based on the same conduct and by seeking to entrench themselves. Finally, Count IV purported to assert a derivative claim for a declaration that any amendment to Article II, Section 2 requires the approval of 80% of Enzo’s shareholders. On July 16, 2020, the day before the defendants’ motion to dismiss was due, plaintiffs asked the Court to dismiss their claims without prejudice. Defendants asked plaintiffs to dismiss the claims with prejudice, but they refused. On July 17, 2020, the Court dismissed the claims without prejudice. If plaintiffs reassert the claims, defendants intend to vigorously defend against them.

On November 27, 2020, the Company brought an action in the United States District Court for the Southern District of New York against Harbert Discovery Fund, LP, Harbert Discovery Co-Investment Fund I, LP, Harbert Fund Advisors, Inc., Harbert Management Corp. and Kenan Lucas. The Company alleges the defendants made false and misleading representations, or omitted to state material facts necessary to make their statements not misleading, in proxy materials they disseminated seeking the election to the Company’s Board of Directors at its 2019 Annual Meeting of two candidates they nominated, in violation of Section 14(a) of the 1934 Exchange Act and Rule 14a-9 thereunder. The Company seeks damages and injunctive relief. On February 15, 2021, Defendants filed a motion to dismiss. On March 8, 2021, the Company filed its opposition to that motion. On March 18, 2021 defendants filed their reply in further support of the motion. The motion is sub judice.

There can be no assurance that the Company will be successful in any of these litigations. Even if the Company is not successful, management does not believe that there will be a significant adverse monetary impact on the Company. The Company is party to other claims, legal actions, complaints, and contractual disputes that arise in the ordinary course of business. The Company believes that any liability that may ultimately result from the resolution of these matters will not, individually or in the aggregate, have a material adverse effect on its financial position or results of operations.

As described in Note 3, third-party payers, including government programs, may decide to deny payment or recoup payments for testing that they contend was improperly billed or not medically necessary, against their coverage determinations, or for which they believe they have otherwise overpaid (including as a result of their own error), and we may be required to refund payments already received. During the third fiscal quarter of 2019, a significant third-party payer informed us outside of their typical business practice that they believe it overpaid the Company during certain periods of fiscal 2018. The Company disputed these claims and formally sent legal appeal letters to the payer.

During the fiscal 2020 period, we recorded $0.8 million in legal and related expenses as a result of reduced reimbursements this payer made to us. In April 2020, we and the payer entered into a settlement agreement and release whereby the parties agreed that the $0.8 million previously withheld by the payer shall fully and completely satisfy the dispute.

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

The following discussion of our financial condition and results of operations should be read in conjunction with our consolidated financial statements and related notes and other information included elsewhere in this Quarterly Report on Form 10-Q.

Forward-Looking Statements

Our disclosure and analysis in this report, including but not limited to the information discussed in this Item 2, contain forward-looking information about our Company’s financial results and estimates, business prospects and products in research and development that involve substantial risks and uncertainties. From time to time, we also may provide oral or written forward-looking statements in other materials we release to the public. Forward-looking statements give our current expectations or forecasts of future events. You can identify these statements by the fact that they do not relate strictly to historic or current facts. They use words such as “anticipate”, “estimate”, “expect”, “project”, “intend”, “plan”, “believe”, “will”, and other words and terms of similar meaning in connection with any discussion of future operations or financial performance.

In particular, these include statements relating to future actions, prospective products or product approvals, future performance or results of current and anticipated products, sales efforts, expenses, interest rates, foreign currency rates, intellectual property matters, the outcome of contingencies, such as legal proceedings, impacts of the COVID-19 pandemic and measures we have taken in response, and financial results. We cannot guarantee that any forward-looking statement will be realized, although we believe we have been prudent in our plans and assumptions. Achievement of future results is subject to risks, uncertainties and inaccurate assumptions. Should known or unknown risks or uncertainties materialize, or should underlying assumptions prove inaccurate, actual results could vary materially from past results and those anticipated, estimated or projected. As a result, investors are cautioned not to place undue reliance on any of our forward-looking statements. Investors should bear this in mind as they consider forward-looking statements. We do not assume any obligation to update or revise any forward-looking statement that we make, even if new information becomes available or other events occur in the future. We are also affected by other factors that may be identified from time to time in our filings with the Securities and Exchange Commission, some of which are set forth in Item 1A - Risk Factors in our Form 10-K filing for the July 31, 2020 fiscal year. You are advised to consult any further disclosures we make on related subjects in our Forms 10-Q, 8-K and 10-K reports to the Securities and Exchange Commission. Although we have attempted to provide a list of important factors which may affect our business, investors are cautioned that other factors may prove to be important in the future and could affect our operating results.

You should understand that it is not possible to predict or identify all such factors or to assess the impact of each factor or combination of factors on our business. Consequently, you should not consider any such list to be a complete set of all potential risks or uncertainties.

Impact of COVID-19 pandemic

COVID-19 has severely impacted the economy of the United States and other countries around the world. Federal, state and local governmental policies and initiatives designed to reduce the transmission of COVID-19 have resulted in, among other things, a significant reduction in physician office visits, the cancellation of elective medical procedures, customers of our products closing or severely curtailing their operations (voluntarily or in response to government orders), and the adoption of work-from-home or shelter-in-place policies. The COVID-19 impact on the Company’s operations is consistent with the overall industry and publicly issued statements from competitors, partners, and vendors.

Enzo was granted FDA Emergency Use Authorization (EUA) for our molecular diagnostic and serological testing for COVID-19 and related antibody testing options. We have also been granted an EUA for our sample collection kit, an innovative virus-inactivating specimen collection media that lessens transmission risks for healthcare providers and clinical laboratory personnel. Other innovations include the development of more relevant positive controls for the tests, and improved sensitivity.

23

In the third quarter of our current fiscal year ending July 31, 2021, our non-COVID-19 accessions returned to and slightly exceeded prior year period levels. With the addition of COVID-19 testing, total accession volume for the fiscal third quarter ended April 30, 2021 exceeded accession volume in both the sequential or second fiscal quarter ended January 31, 2021 and the prior year fiscal third quarter ended April 30, 2020. However, it is too early to determine the long term significance of the positive impact from increased testing and the Company’s proprietary product offerings on revenue, profitability and cash flow.

The extent to which our businesses may continue to be affected by the COVID-19 pandemic will largely depend on both current and future developments, including its duration, spread and emergence of variants, its treatment with authorized vaccines and vaccines in various stages of development and federal approval, and work and travel advisories and restrictions, and the timing of their easing, all of which are highly uncertain and cannot be reasonably predicted at this time.

We fully expect COVID-19 volume to decline in the quarters ahead as the percentage of Americans who are vaccinated increases. Global supply chain issues due to the pandemic continue to hamper both the manufacturing of products within the life science division as well as testing capabilities in the clinical laboratory.

The Coronavirus Aid, Relief, and Economic Security Act (CARES Act)

In March 2020, in response to the COVID-19 pandemic, the CARES Act was signed into law. The CARES Act provides numerous tax provisions and other stimulus measures. The CARES Act also includes a number of benefits that are applicable to us and other healthcare providers including, but not limited to:

● Providing clinical laboratories a one-year reprieve from the Centers for Medicare and Medicaid Services (CMS) private payer prices reporting requirements under the Protecting Access to Medicare Act (“PAMA”) as well as a one-year delay of a reimbursement rate reduction of 15% for clinical laboratory services provided under Medicare that was scheduled to take place starting January 1, 2021. Further revisions of the Medicare Clinical Laboratory Fee Schedule (CLFS) for calendar years after 2021 will be based on future surveys of private payer market rates. Medicare and Medicaid reimbursement reduction for calendar years 2022-2024 is capped by PAMA at 15% annually, which we estimate could then negatively impact our annualized Medicare and Medicaid revenues by approximately $2.3 million. In this regard, the American Clinical Laboratory Association (ACLA) has filed a federal civil action challenging the legal basis for the private payer data collection methodology CMS used to derive the data from which median prices were calculated. ACLA continues to work with Congress on potential legislative reform of PAMA, which if adopted could reduce the negative impact of PAMA as currently implemented by CMS. The long-term effect of these efforts on Medicare CLFS rates is not determinable

● Appropriating $100 billion to health care providers for related expenses or lost revenues that are attributable to the COVID-19 pandemic. In April 2020, we received from Medicare a CARES Act Relief Payment grant of approximately $750 from the initial tranche and in July 2020 we received a second grant of approximately $750.

● Allocated $349 billion to small businesses as Payment Protection Program (PPP) loans through the Small Business Administration (SBA). In April 2020, we received approximately $7.0 million from the initial tranche of this program.

● Providing an advance on testing services payments which can be either paid back at any time or earned back starting one year from receipt. In April 2020 we applied for and received a Medicare advance payment of $2.5 million.

● Suspended Medicare sequestration from May 2020 to December 2020. The Consolidated Appropriations Act of 2021 extended the suspension period to March 31, 2021. An Act to Prevent Across-the-Board Direct Spending Cuts, and for Other Purposes, signed into law on April 14, 2021, extended the suspension period to December 31, 2021. We estimate that the suspension of Medicare sequestration resulted in a small benefit to us in the form of higher reimbursement rates for diagnostic testing services performed on behalf of Medicare beneficiaries.

Our genetic test panels are focused on large and growing markets primarily in the areas of personalized medicine, women’s health, infectious diseases and genetic disorders.

In the course of our research and development activities, we have built a substantial portfolio of intellectual property assets, comprised of over 495 issued patents worldwide and over 70 pending patent applications, along with extensive enabling technologies and platforms.

Below are brief descriptions of each of our operating segments (See Note 11 in the Notes to Consolidated Financial Statements):

Enzo Clinical Services is a clinical reference laboratory providing a wide range of clinical services to physicians, medical centers, other clinical labs and pharmaceutical companies. The Company believes having a Clinical Laboratory Improvement Amendments of 1988 (“CLIA”) certified and College of American Pathologists (“CAP”) accredited medical laboratory located in New York provides us the opportunity to more rapidly introduce cutting edge products and services to the clinical marketplace. Enzo Clinical Labs offers an extensive menu of molecular and other clinical laboratory tests and procedures used in patient care by physicians to establish or support a diagnosis, monitor treatment or medication, and search for an otherwise undiagnosed condition. Our laboratory is equipped with state-of-the-art communication and connectivity solutions enabling the rapid transmission, analysis and interpretation of generated data. We operate a full service clinical laboratory in Farmingdale, New York, a network of over 30 patient service centers throughout New York, New Jersey and Connecticut, two free standing “STAT” or rapid response laboratories in New York City and Connecticut, an in-house logistics department, and an information technology department. Under our license in New York State, we are able to offer testing services to clinical laboratories and physicians nationwide.

The Clinical Laboratory Services reporting unit is impacted by various risk factors, including among others, reduced reimbursements from third party payers for testing performed and from recent health care legislation. Despite the growth we have experienced in previous years, there can be no assurance future growth can be achieved. The introduction of new molecular and esoteric tests is expected to increase our revenue per test and could offset impacts from the above factors. The Company anticipates improved profitability with increased service volume.

25

Enzo Products manufactures, develops and markets products and tools for clinical research, drug development and bioscience research customers worldwide. Underpinned by broad technological capabilities, Enzo Life Sciences has developed proprietary products used in the identification of genomic information by laboratories around the world.

Consolidated Results:

The “2021 period” and the “2020 period” refer to the three months ended April 30, 2021 and April 30, 2020, respectively, which represent the third quarters of the Company’s fiscal year ending July 31.

Impacts of COVID-19

In July 2020, Enzo was granted FDA Emergency Use Authorization (EUA) for its molecular diagnostic and serological testing for COVID-19 and related antibody testing options. Enzo’s innovations include virus-inactivating specimen collection media to lessen transmission risks for healthcare providers and clinical laboratory personnel, the development of more relevant positive controls for the tests, and improved sensitivity. Due to the effects of the pandemic, accession volume in the April 30, 2021 period exceeded accession volume in the sequential second fiscal quarter ended January 31, 2021 and the prior year third quarter ended April 30, 2020 period due to COVID-19 testing, offsetting reductions in non-COVID-19 accessions due to the restrictive effects of COVID-19. At this time, it is too early to determine the long term significance of the positive impact from COVID-19 testing and the Company’s proprietary product offerings on revenue, profitability and cash flow. We fully expect COVID-19 volume to decline in the quarters ahead as the percentage of Americans who are vaccinated increases.

Clinical Services revenues for the 2021 period were $25.0 million compared to $10.5 million in the 2020 period, an increase of $14.5 million or 139% year-over-year. The 2020 period revenues include a CARES Act Relief Payment grant of $0.7 million. Diagnostic testing volume measured by the total number of accessions for all our testing services increased 140% period over period due to the positive impact from COVID-19 testing, resulting in the 2021 period’s revenue increase. COVID-19 testing services have higher reimbursement rates than our core testing resulting in an improvement in our overall liquidation rate for collections. Excluding the impact of COVID-19 testing and the CARES Act grant, revenues for the 2021 period were $0.7 million higher than the 2020 period.

Estimated collection amounts are subject to the complexities and ambiguities of third party payer billing, reimbursement regulations and claims processing, as well as issues unique to Medicare and Medicaid programs, and require us to consider the potential for adjustments when estimating variable consideration in the recognition of revenue in the period that the related services are rendered. The effect of PAMA directly negatively impacted reimbursements from Medicare and Medicaid in the 2021 and 2020 periods by approximately $0.3 million and $0.2 million, respectively.

Product revenues were $7.8 million in the 2021 period and $6.4 million in the 2020 period, an increase of $1.4 million or 21%. The 2020 period was negatively affected by COVID-19 related government policies throughout the world intended to reduce the spread of the pandemic. In the 2021 period, we saw a rebound in all our geographic markets due to their improvement in infection rates resulting in a rebound in demand.

The cost of Clinical Services was $12.7 million in the 2021 period and $9.1 million in the 2020 period, an increase of $3.6 million from increased COVID-19 testing volume. Utilizing our internal manufacturing capabilities, we reduced some of our reliance on reagents sourced from third parties. The gross profit margin on Clinical Services revenues in the 2021 period improved to 49% versus 12.9% in the 2020 period due to the high margin on COVID-19 testing and liquidation rate improvements The 2020 period was negatively impacted by the lower testing volumes because of the pandemic and its impact on fixed costs coverage.

The cost of Product revenues was $4.0 million in the 2021 period and $3.3 million in the 2020 period, an increase of $0.7 million or approximately 20%. The gross profit margin on Products was 48% in the both the 2021 and 2020 periods. The gross margin in the 2021 period was impacted by the return of higher margin sales in the U.S market, tempered by intercompany COVID-19 sales.

Research and development expenses were $0.8 million in the 2021 period and $1.1 million in the 2020 period, a decrease of $0.3 million or 28%. The decrease is attributable primarily to the Clinical Services division, where with the increased commercialization of COVID-19 testing, certain research and development resources transitioned to testing services in the current period.

27

Selling, general and administrative expenses were $12.1 million during the 2021 period versus $11.1 million during the 2020 period, an increase of $1.0 million or 9%. The Clinical Services expense increased $1.1 million primarily due to higher sales commissions and support services compensation resulting from higher revenues and activity from COVID-19, partially offset by the impact of cost savings initiatives undertaken throughout our fiscal year that ended July 31, 2020. The Life Sciences Products expense increased $0.1 million due to an increase in information technology costs. The Other segment decreased $0.3 million primarily due to lower self-insured healthcare benefit costs, partially offset by higher consulting fees.

Legal and related expenses were $1.1 million during the 2021 period compared to $1.9 million in the 2020 period, a decrease of $0.8 million or 45% year-over-year. The 2020 period included costs related to contested proxy activities.

Interest income, net was $0.1 million in both the 2021 and 2020 periods. In the 2021 period we earned interest on marketable securities in bond funds made at the beginning of the 2021 period. In the 2020 period we earned interest in money market funds, which earned a significant yield prior to the Federal Reserve’s interest rate cuts as it targeted near zero interest rates in response to COVID-19. Interest income, net is net of interest paid on a mortgage in both periods.

The foreign currency revaluation loss recognized by the Life Sciences Products segment during the 2021 period was $0.1 million compared to $0.4 million in the 2020 period, an improvement of $0.3 million. The larger revaluation loss in the 2020 period was due to significant depreciation of the British pound versus the U.S. dollar at the end of that period compared to the start if the period. The change in the exchange rates of our functional currencies versus the U.S. dollar was less significant at the end of the 2021 period compared to the start.

Consolidated Results:

The “2021 period” and the “2020 period” refer to the nine months ended April 30, 2021 and April 30, 2020, respectively, which represent the first three quarters of the Company’s fiscal year ending July 31.

Clinical Services revenues for the 2021 period were $70.2 million compared to $35.8 million in the 2020 period, an increase of $34.4 million or 96% year-over-year. The 2020 period revenues include a CARES Act Relief Payment grant of $0.7 million. Due to COVID-19, diagnostic testing volume measured by the total number of accessions for all our testing services increased approximately 80% period over period, resulting in the 2021 period’s revenue increase. COVID-19 testing services have higher reimbursement rates than our core testing resulting in an improvement in our overall liquidation rate for collections. COVID-19 testing offset the impact of the period over period decline in core testing volume as a result of the restrictive effects of COVID-19.

Estimated collection amounts are subject to the complexities and ambiguities of third party payer billing, reimbursement regulations and claims processing, as well as issues unique to Medicare and Medicaid programs, and require us to consider the potential for adjustments when estimating variable consideration in the recognition of revenue in the period that the related services are rendered. The effect of PAMA directly negatively impacted reimbursements from Medicare and Medicaid in the 2021 and 2020 periods by approximately $1.1 million and $0.9 million, respectively.

Product revenues were $22.7 million in the 2021 period and $20.7 million in the 2020 period, an increase of $2.0 million or 10%. The negative effect of COVID-19 related government policies intended to reduce the spread of the pandemic impacted our Products revenues in the U.S. markets more than in markets in the rest of the world during the 2020 period. The 2021 period increase came mainly from markets outside the U.S., due to their improvement in infection rates and a rebound in demand. The U.S. market also increased slightly.

The cost of Clinical Services was $37.4 million in the 2021 period and $30.4 million in the 2020 period, an increase of $7.0 million from increased COVID-19 testing volume. Utilizing our internal manufacturing capabilities we reduced some of our reliance on reagents sourced from third parties. The gross profit margin on Clinical Services revenues in the 2021 period was approximately 47% versus 15% in the 2020 period. In the 2021 period, the high margin on COVID-19 testing and liquidation rate improvements offset the effect of reduced volumes of our core testing services.

The cost of Product revenues was $11.7 million in the 2021 period and $10.2 million in the 2020 period, an increase of $1.5 million or 15%. The gross profit margin on Products was 48% in the 2021 period and 51% in the 2020 period, negatively impacted by an increase in headcount and the cost of production materials.

Research and development expenses were $2.4 million in the 2021 period and $3.3 million in the 2020 period, a decrease of $0.9 million or 27%. The decrease is attributable primarily to the Clinical Services division, where with the increased commercialization of COVID-19 testing, certain research and development resources transitioned to testing services in the current period.

Selling, general and administrative expenses were $33.1 million during the 2021 period versus $32.9 million during the 2020 period, an increase of $0.2 million or 1%. The Clinical Services expense increased $1.5 million primarily due to higher sales commissions and support services compensation resulting from higher revenues and activity from COVID-19, partially offset by the impact of cost savings initiatives undertaken throughout our fiscal year that ended July 31, 2020. The Other segment decreased $1.3 million primarily due to lower self-insured healthcare benefit costs. The Life Sciences Products expense decreased $0.1 million due to lower travel and other in person marketing expenses.

Legal and related expenses were $4.0 million during the 2021 period compared to $5.7 million in the 2020 period, a decrease of $1.7 million or 30%. There were contested proxy activities in both periods, but we incurred legal expenses relating to the contested proxy throughout the 2020 period compared to only during the latter half of the 2021 period.

Interest expense, net was $0.1 million in the 2021 period versus interest income, net of $0.5 million in the 2020 period, an unfavorable variance of $0.6 million, and represents interest on cash and cash equivalents and marketable securities net of interest expense, primarily on a mortgage. During the latter three months of the 2021 period, we began to earn interest on marketable securities in bond funds as no interest was being earned on cash in money market funds due to the actions by the Federal Reserve to cut its target interest rates to near zero in response to COVID-19. During most of the 2020 period, we earned interest in money market funds, which earned a significant yield prior to the Federal Reserve’s interest rate cuts as it targeted near zero interest rates.

29

The foreign currency revaluation gain recognized by the Life Sciences Products segment during the 2021 period was $0.4 million compared to a revaluation loss $0.1 million in the 2020 period, a favorable variance of $0.5 million. The 2021 period revaluation gain was due to significant appreciation of the British pound versus the U.S. dollar as of the end of the period compared to its start. The change in the exchange rates of our functional currencies versus the U.S. dollar was less significant at the end of the 2020 period compared to the start.

Liquidity and Capital Resources

At April 30, 2021, the Company had cash and cash equivalents and marketable securities totaling $45.0 million of which $1.5 million was in foreign accounts, as compared to cash and cash equivalents of $47.9 million, of which $0.9 million was in foreign accounts at July 31, 2020. It is the Company’s current intent to permanently reinvest these foreign funds outside of the United States, and its current plans do not demonstrate a need to repatriate them to fund its United States operations. The Company had working capital of $42.1 million at April 30, 2021, an increase of $6.1 million, compared to $36.0 million at July 31, 2020. The increase in working capital during the nine months ended April 30, 2021 was primarily due to increases in current assets such as accounts receivable and inventories, partially offset by a decrease in cash, and a decrease in accounts payable.

Net cash provided by operating activities during the fiscal 2021 period was approximately $0.3 million, compared to cash used in operations of $12.1 million during the fiscal 2020 period, an improvement of approximately $12.4 million. The net cash provided in the 2021 period was due primarily to net income of $4.6 million and non-cash expenses of approximately $2.8 million which were offset by a net increase of $7.1 million in operating assets and liabilities including, but not limited to, accounts receivable and inventories. The net cash used in the 2020 period was due to a net loss of $25.2 million partially offset by non-cash expenses of $3.5 million and a net decrease of $9.6 million in operating assets and liabilities.

Net cash used in investing activities during the fiscal 2021 period was approximately $32.9 million as compared to $0.7 million in the 2020 period, an increase of $32.2 million. During the 2021 period, we purchased marketable securities totaling $30.0 million. Capital expenditures during the 2021 period also increased $2.2 million compared to the 2020 period. Cash used in financing activities in fiscal 2021 was $0.2 million for payments related to a mortgage and finance leases. Cash provided by financing activities in fiscal 2020 was $7.1 million net, and was due to the PPP and Corona Krise loans.

As of April 30, 2021, we have a $7.0 million loan from the Small Business Administration Paycheck Protection Program (PPP) received during the fiscal year ended July 31, 2020. The PPP loan bears interest of 1% per annum. All or a portion of the PPP Loan, including interest, could be forgiven by the SBA by applying for forgiveness and providing acceptable documentation that demonstrates the funds were used as required by the terms of forgiveness and in accordance with the SBA’s requirements. In April 2021 we submitted our PPP loan forgiveness application and the loan necessity questionnaire to the SBA through Citibank N.A. our intermediary lending bank. According to the SBA, its review may take up to 90 calendar days from the receipt of the loan forgiveness application and loan necessity questionnaire. Due to complexities with respect to loan forgiveness calculations and government pronouncements with respect to expenditure eligibility, we did not recognize any loan forgiveness as of April 30, 2021 and have classified the loan as other short term debt as we expect to earn loan forgiveness on most, if not all of the loan during the current fiscal year. See Note 7 in the notes to consolidated financial statements. No assurance can be given that we will obtain forgiveness of the PPP loan in whole or in part by July 31, 2021

As of April 30, 2021 we have a mortgage principal balance of $4.2 million entered into for the purchase of a building facility, which bears a fixed interest rate of 5.09% per annum. It requires monthly mortgage payments of $30. Our obligations under the mortgage agreement are secured by the new facility and by a $750 cash collateral deposit with the mortgagee as additional security, which is included in other assets as of April 30 2021. Effective October 19, 2020, the Company and the mortgagee agreed to a covenant restructure whereby the mortgagee waived the Company’s financial ratio covenant for the fiscal period ended July 31, 2020 and modified the mortgage to replace that covenant with a liquidity covenant. The liquidity covenant requires that we own and maintain at all times, and throughout the remaining term of the loan, at least $25 million of liquid assets, defined as time deposits, money market accounts and commercial paper, and obligations issued by the U.S. government or any of its agencies. The cash collateral agreement was also modified to require compliance with the liquidity covenant for two consecutive fiscal years before the collateral is released back to us. As of April 30, 2021, the Company was in compliance with financial and liquidity covenants related to this mortgage.

30

We believe that our current cash and cash equivalents level, marketable securities, and utilization of the Controlled Equity Offering program if necessary, as disclosed in Note 10 in the Notes to Consolidated Financial Statements are sufficient for its foreseeable liquidity and capital resource needs over at least the next twelve (12) months, although there can be no assurance that future events will not alter such view. Although there can be no assurances, in the event additional capital is required, we believe we have the ability to raise additional funds through equity offerings or other sources. Our liquidity plans are subject to a number of risks and uncertainties, including those described in the Item 1A. “Risk Factors” section of our Form 10-K for the year ended July 31, 2020, some of which are outside our control. Macroeconomic conditions could limit our ability to successfully execute our business plans and therefore adversely affect our liquidity plans.

Contractual Obligations

There have been no material changes to our Contractual Obligations as reported in our Form 10-K for the fiscal year ended July 31, 2020. Management is not aware of any material claims, disputes or settled matters concerning third party reimbursement that would have a material effect on our financial statements, except as disclosed in Note 12 to the Consolidated Financial Statements.

Off-Balance Sheet Arrangements

The Company does not have any “off-balance sheet arrangements” as such term is defined in Item 303(a)(4) of Regulation S-K.

Critical Accounting Policies

The Company’s discussion and analysis of its financial condition and results of operations are based upon Enzo Biochem, Inc.’s consolidated financial statements, certain information and footnote disclosure, normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States, have been condensed or omitted, as permitted under rules promulgated by the Security and Exchange Commission. The preparation of these financial statements requires the Company to make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses. These estimates and judgments also affect related disclosure of contingent assets and liabilities.

Estimates

On an on-going basis, we evaluate our estimates, including those related to contractual expense, allowance for uncollectible accounts, inventory, operating lease liabilities, goodwill and income taxes.

The Company bases its estimates on experience and on various other assumptions that are believed to be reasonable under the circumstances, the results of which form the basis for making judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

Revenues – Clinical Services

Contractual Adjustment

The Company’s estimate of contractual adjustment is based on significant assumptions and judgments, such as its interpretation of payer reimbursement policies, and bears the risk of change. The estimation process is based on the experience of amounts approved as reimbursable and ultimately settled by payers, versus the corresponding gross amount billed to the respective payers. The contractual adjustment is an estimate that reduces gross revenue, based on gross billing rates, to amounts expected to be approved and reimbursed.

Gross billings are based on a standard fee schedule we set for all third party payers, including Medicare, HMO’s and managed care. The Company adjusts the contractual adjustment estimate quarterly, based on its evaluation of current and historical settlement experience with payers, industry reimbursement trends, and other relevant factors. The other relevant factors that affect our contractual adjustment include the monthly and quarterly review of: 1) current gross billings and receivables and reimbursement by payer, 2) current changes in third party arrangements and 3) the growth of in-network provider arrangements and managed care plans specific to our Company.

31

Our clinical business is primarily dependent upon reimbursement from third-party payers, such as Medicare (which principally serves patients 65 and older) and insurers. We are subject to variances in reimbursement rates among different third-party payers, as well as constant changes of reimbursement rates. We expect the efforts to impose reduced reimbursement, more stringent payment policies, and utilization and cost controls by government and other payers to continue. Changes that decrease reimbursement rates or coverage would negatively impact our revenues. The number of individuals covered under managed care contracts or other similar arrangements has grown over the past several years and may continue to grow in the future. In addition, Medicare and other government healthcare programs continue to shift to managed care. These trends will continue to reduce our revenues from these programs.

During the three months ended April 30, 2021 and 2020, the contractual adjustment percentages, determined using current and historical reimbursement statistics, were 81.2% and 87.1%, respectively, of gross billings, respectively. During the nine months ended April 30, 2021 and 2020, the contractual adjustment percentages, determined using current and historical reimbursement statistics, were 82.2% and 88.2%, respectively, of gross billings, respectively. The improvement in both periods is the result of COVID-19 testing reimbursements more closely matching our gross billing charges and fewer payer denials than what we experience for our core testing services. In general, the Company believes a decline in reimbursement rates or a shift to managed care or similar arrangements may be offset by the positive impact of an increase in the number of molecular tests we perform. However, there can be no assurance that we can increase the number of tests we perform or that if we do increase the number of tests we perform, that we can maintain that higher number of tests performed, or that an increase in the number of tests we perform would result in increased revenue.

The Company estimates (by using a sensitivity analysis) that each 1% point change in the contractual adjustment percentage could result in a change in clinical services revenues of approximately $3.9 million and $3.0 million for the nine months periods ended April 30, 2021 and 2020 respectively, and a change in the net accounts receivable of approximately $0.6 million as of April 30, 2021.

Our clinical services financial billing system records gross billings using a standard fee schedule for all payers and does not record contractual adjustment by payer at the time of billing. Therefore, we are unable to quantify the effect contractual adjustments recorded during the current period have on revenue recorded in a previous period. However, we can reasonably estimate our monthly contractual adjustment to revenue on a timely basis based on our quarterly review process, which includes:

● an analysis of industry reimbursement trends;

● an evaluation of third-party reimbursement rates changes and changes in reimbursement arrangements with third-party payers;

● a rolling monthly analysis of current and historical claim settlement and reimbursement experience statistics with payers; and

● an analysis of current gross billings and receivables by payer.

Government assistance grant income

Government assistance grants which are unconditional when received and intended to compensate for expenses incurred or replace lost revenues are recognized when those expenses are incurred or during the period that the lost revenues is experienced, and are included in revenues.

Accounts Receivable

Accounts receivable are reported at realizable value, net of allowances for doubtful accounts, which is estimated and recorded in the period of the related revenue.

The following is a table of the Company’s net accounts receivable by services and by products. Net receivables for Clinical Services are detailed by billing category and as a percent to its total net receivables. At April 30, 2021 and July 31, 2020, approximately 69% of the Company’s net accounts receivable relates to its Clinical Laboratory Services business, which operates in the New York, New Jersey and Connecticut medical communities.

32

The accounts receivable balance for Life Science products includes foreign receivables of $1.0 million or 28% and $1.0 million or 34% of its total receivables as of April 30, 2021 and July 31, 2020, respectively.

Net accounts receivable

Billing category	As of April 30, 2021				As of July 31, 2020
Clinical Services
Third party payers	$	4,236	53	%	$	2,455	40	%

HMO’s		679	9			797	13
Total Clinical Services		7,915	100	%		6,180	100	%
Total Life Sciences		3,560				2,961
Total accounts receivable - net	$	11,475			$	9,141

The Company’s ability to collect outstanding receivables from third party payers is critical to its operating performance and cash flows. The primary collection risk lies with uninsured patients or patients for whom primary insurance has paid but a patient portion remains outstanding. The Company also assesses the current state of its billing functions in order to identify any known collection or reimbursement issues in order to assess the impact, if any, on the allowance estimates, which involves judgment.

The Company believes that the collectability of its receivables is directly linked to the quality of its billing processes, most notably, those related to obtaining the accurate patient information in order to bill effectively for the services provided. Should circumstances change (e.g. shift in payer mix, decline in economic conditions or deterioration in aging of receivables), our estimates of net realizable value of receivables could be reduced by a material amount.

Billing for clinical services is complicated because of many factors, especially: the differences between our standard gross fee schedule for all payers and the reimbursement rates of the various payers we deal with, disparity of coverage and information requirements among the various payers, and disputes with payers as to which party is responsible for reimbursement.

The following table indicates the Clinical Services aged gross receivables by payer group which is prior to adjustment to gross receivables for: 1) contractual adjustment, 2) fully reserved balances not yet written off, and 3) other revenue adjustments.

Income Taxes

The Company accounts for income taxes under the liability method of accounting for income taxes. Under the liability method, 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. The liability method requires that any tax benefits recognized for net operating loss carry forwards and other items be reduced by a valuation allowance where it is not more likely than not the benefits will be realized in the foreseeable future. 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. Under the liability method, 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.

It is the Company’s policy to provide for uncertain tax positions and the related interest and penalties based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. To the extent the Company prevails in matters for which a liability for an unrecognized tax benefit is established or is required to pay amounts in excess of the liability, the Company’s effective tax rate in a given financial statement period may be affected.

Inventory

The Company values inventory at the lower of cost (first-in, first-out) or net realizable value, which approximates market. Work-in-process and finished goods inventories consist of material, labor, and manufacturing overhead. Write downs of inventories to net realizable value are based on a review of inventory quantities on hand and estimated sales forecasts based on sales history and anticipated future demand. Unanticipated changes in demand could have a significant impact on the value of our inventory and require additional write downs of inventory which would impact our results of operations.

Leases - right of use assets and operating lease liabilities

The Company determines if an arrangement is or contains a lease at contract inception. The Company leases buildings, office space, patient service centers, and equipment primarily through operating leases, and equipment through a limited number of finance leases. Generally, a right-of-use asset, representing the right to use the underlying asset during the lease term, and a lease liability, representing the payment obligation arising from the lease, are recognized on the balance sheet at lease commencement based on the present value of the payment obligation. For operating leases, expense is recognized on a straight-line basis over the lease term. For finance leases, interest expense on the lease liability is recognized using the effective interest method and amortization of the right-of-use asset is recognized on a straight-line basis over the shorter of the estimated useful life of the asset or the lease term. Short-term leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term.

The Company primarily uses its incremental borrowing rate in determining the present value of lease payments as the Company’s leases generally do not provide an implicit rate. The Company has lease agreements with (i) right-of-use asset payments and (ii) non-lease components (i.e. payments related to maintenance fees, utilities, etc.,) which have generally been combined and accounted for as a single lease component.

On at least an annual basis, we perform a review of our business to determine if events or changes in circumstances have occurred that indicate that it is more likely than not that the carrying amount of an asset group, including long lived assets such as right of use assets, is not recoverable. If such events or changes in circumstances were deemed to have occurred, we would perform an impairment test of such long lived assets and record any noted impairment loss. Should the impact of the COVID-19 pandemic become significantly worse than currently expected, it is possible that we could incur impairment charges on long lived assets in the future.

34

Goodwill

Goodwill represents the excess of the cost of an acquisition over the fair value of the net assets acquired. The Company tests goodwill and long-lived assets annually as of the first day of the fourth quarter, or more frequently if indicators of potential impairment exist. In assessing goodwill and long-lived assets for impairment, the Company has the option to perform a qualitative assessment to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If the Company determines that it is not more likely than not that the fair value of a reporting unit is less than its carrying amount, the Company is not required to perform a quantitative test in assessing goodwill and long-lived assets for impairment. However, if the Company concludes otherwise or elects not to perform the qualitative assessment, then it identifies the reporting units and compares the fair value of each of these reporting units to their respective carrying amount. If the carrying amount of the reporting unit is less than its fair value, no impairment exists. If the carrying amount of the reporting unit is higher than its fair value, the impairment charge is the amount by which the carrying amount exceeds its fair value, not to exceed the total amount of goodwill and intangibles allocated to the reporting unit.

On at least an annual basis, we perform a review of our business to determine if events or changes in circumstances have occurred that indicate that it is more likely than not that the fair value of a reporting unit with goodwill is less than its carrying value. If such events or changes in circumstances were deemed to have occurred, we would perform an impairment test of goodwill and record any noted impairment loss. Should the impact of the COVID-19 pandemic become significantly worse than currently expected, it is possible that we could incur impairment charges in the future.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

We are exposed to market risk from changes in foreign currency exchange rates resulting from acquisitions with foreign locations (See Item 1A. Risk Factors section of the Form 10-K for the fiscal year ended July 31, 2020) that could impact our results of operations and financial position. We do not currently engage in any hedging or market risk management tools.

Foreign Currency Exchange Rate Risk

The financial reporting of our non-U.S. subsidiaries is denominated in currencies other than the U.S. dollar. Since the functional currency of our non-U.S. subsidiaries is the local currency, foreign currency translation adjustments are accumulated as a component of accumulated other comprehensive income in stockholders’ equity. Assuming a hypothetical increase of 10% in the value of the U.S. dollar versus foreign currencies at April 30, 2021, our assets and liabilities would decrease by $0.4 million and $0.1 million, respectively, and our net sales and net earnings (loss) would decrease by $1.1 million and $0.1 million, respectively, on an annual basis.

We also maintain intercompany balances and loans with subsidiaries in different local currencies. These amounts are at risk of foreign exchange losses if exchange rates fluctuate. Assuming a hypothetical increase of 10% in the value of the U.S. dollar versus foreign currencies, our pre-tax earnings (loss) would be unfavorably impacted by approximately $1.8 million on an annual basis.

Interest Rate Risk

As of April 30, 2021, we have fixed interest rate financing on a building mortgage, equipment finance leases, and the PPP loan from the SBA.

Item 4. Controls and Procedures

(a) Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, the Company’s management conducted an evaluation (as required under Rules 13a-15(b) and 15d-15(b) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”)) of the Company’s “disclosure controls and procedures” (as such term is defined under the Exchange Act), under the supervision and with the participation of the principal executive officer and the principal financial officer. Based on this evaluation, the principal executive officer and the principal financial officer concluded that the Company’s disclosure controls and procedures are effective as of the end of the period covered by this report. Notwithstanding the foregoing, a control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that it will detect or uncover failures within the Company to disclose material information otherwise required to be set forth in the Company’s periodic reports.

(b) Changes in Internal Controls over Financial Reporting

There were no changes in our internal control over financial reporting that occurred during the quarter ended April 30, 2021 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

Accounting Policies [Abstract]

Basis of Presentation

Note 1 – Basis of Presentation

The accompanying consolidated financial statements include the accounts of Enzo Biochem, Inc. and its wholly-owned subsidiaries, Enzo Life Sciences, Enzo Clinical Labs, Enzo Therapeutics, Enzo Realty LLC and Enzo Realty II LLC, collectively or with one or more of its subsidiaries referred to as the “Company” or “Companies”. The Company has three reportable segments: Clinical Services, Products, and Therapeutics. The consolidated balance sheet as of April 30, 2021, the consolidated statements of operations, comprehensive income (loss) and stockholders’ equity for the three and nine months ended April 30, 2021, and the consolidated statements of cash flows for the nine months ended April 30, 2021 (the “interim statements”) are unaudited. In the opinion of management, all adjustments (which include normal recurring adjustments) necessary to present fairly the financial position and operating results for the interim periods have been made. Certain information and footnote disclosure, normally included in annual financial statements prepared in accordance with accounting principles generally accepted in the United States, have been condensed or omitted. The interim statements should be read in conjunction with the consolidated financial statements for the fiscal year ended July 31, 2020 and notes thereto contained in the Company’s Annual Report on Form 10-K filed with the Securities and Exchange Commission. The consolidated balance sheet at July 31, 2020 has been derived from the audited financial statements at that date. The results of operations for the nine months ended April 30, 2021 are not necessarily indicative of the results that may be expected for the fiscal year ending July 31, 2021.

While the rate of transmission of COVID-19 is declining in the US and Europe, it continues to spread in other parts of the world and negatively impact the world economy. Federal, state and local governmental policies and initiatives designed to reduce the transmission of COVID-19 have resulted in, among other things, a significant reduction in physician office visits, the cancellation of elective medical procedures, customers of our products remaining closed or continuing to severely curtail their operations (voluntarily or in response to government orders), and the continuation of work-from-home or shelter-in-place policies. The COVID-19 impact on the Company’s operations is consistent with the overall industry and publicly issued statements from competitors, partners, and vendors.

The extent to which our businesses may continue to be affected by the COVID-19 pandemic will largely depend on both current and future developments, including its duration, the emergence and spread of variants, its treatment with authorized vaccines and vaccines in various stages of development and federal approval, work and travel advisories and restrictions, and the timing of their easing, all of which are highly uncertain and cannot be reasonably predicted at this time. Global supply chain issues due to the pandemic continue to hamper both the manufacturing of products within the life science division as well as testing capabilities in the clinical laboratory.

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“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 financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

COVID 19

The extent to which the COVID-19 pandemic impacts the Company’s business and financial results will depend on numerous evolving factors including, but not limited to: the magnitude and duration of the COVID-19 pandemic, the extent to which it will impact worldwide macroeconomic conditions including, but not limited to, employment rates and health insurance coverage, the speed of the anticipated recovery, and governmental and business reactions to the pandemic. The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 as of April 30, 2021 and through the date of this report. The accounting matters assessed included, but were not limited to, the Company’s patient self-pay revenue concessions and credit losses in the Clinical Services segment, accounts receivable, inventories and the carrying value of goodwill and other long-lived assets. The Company’s future assessment of the magnitude and duration of COVID-19, as well as other factors, could result in additional material impacts to the Company’s consolidated financial statements in future reporting periods. We fully expect COVID-19 volume to decline in the quarters ahead as the percentage of Americans who are vaccinated increases.

Effect of New Accounting Pronouncements

Pronouncements Issued but Not Yet Adopted

In June 2016, FASB issued ASU No. 2016-13 Financial Instruments – Credit Losses (Topic 326). This standard, as amended, changes the impairment model for most financial instruments, including trade receivables, from an incurred loss method to a new forward-looking approach, based on expected losses. The estimate of expected credit losses will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. Adoption of this standard is required for our annual and interim periods beginning August 1, 2023 as long as we continue to qualify as a smaller reporting company at the end of fiscal 2022, and must be adopted using a modified retrospective transition approach. We are currently assessing the impact of the adoption of this standard on our results of operations, financial position and cash flows.

In December 2019, the FASB issued ASU No. 2019-12 Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. The amendments in the ASU simplify the accounting for income taxes by removing certain exceptions to the general principles of Topic 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this ASU are required for our annual and interim periods beginning August 1, 2021. The adoption of the amendments in this ASU is not expected to have a material impact on our consolidated results of operations, financial position or cash flows

We reviewed all other recently issued accounting pronouncements and have concluded they are not applicable or not expected to be significant to the accounting for our operations.

Concentration Risk

Other than the Medicare program, two providers whose programs are included in the “Third-party payers” and “Health Maintenance Organizations” (“HMO’s”) categories represent approximately 36% and 35% of Clinical Services net revenue for the three and nine month periods ended April 30, 2021. Other than the Medicare program, one provider whose programs are included in those categories represents approximately 21% of Clinical Services net revenue for both the three and nine month periods ended April 30, 2020. As of April 30, 2021, the Medicare program represents 15%, a provider in the third party category represents 13%, and a government payer in the patient self-pay category represents 10% of Clinical Services net receivables.

Income Taxes

The Company accounts for income taxes under the liability method of accounting for income taxes. Under the liability method, 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. The liability method requires that any tax benefits recognized for net operating loss carry forwards and other items be reduced by a valuation allowance where it is not more likely than not the benefits will be realized in the foreseeable future. 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. Under the liability method, 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. It is the Company’s policy to provide for uncertain tax positions, if any, and the related interest and penalties based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. To the extent the Company prevails in matters for which a liability for an unrecognized tax benefit is established or is required to pay amounts in excess of the liability, the Company’s effective tax rate in a given financial statement period may be affected.

Due to our tax net operating loss carryforwards, we do not provide for an income tax provision on pre-tax income in the fiscal 2021 periods. We maintain a full valuation allowance on all tax assets and, as a consequence, do not provide any tax benefit for the fiscal 2020 period losses.

Fair Value Measurements

The Company determines fair value measurements used in its consolidated financial statements based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy. The basis for fair value measurements for each level within the hierarchy is described below with Level 1 having the highest priority and Level 3 having the lowest.

Level 1 Quoted prices in active markets for identical assets or liabilities.

Level 2 Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.

Level 3 Valuations derived from valuation techniques in which one or more significant inputs are unobservable.

Marketable securities

The Company limits its credit risk associated with investments by investing in a mutual fund and an exchange traded fund (ETF) which hold highly rated corporate bonds, asset backed securities, municipal bonds, mortgage obligations and government obligations. These investments are classified as trading securities and are Level 1 fair value investments. As of April 30, 2021, the fair value of these investments was $29,932 and the cost basis was $30,023. We recognized unrealized losses of $91 for the three and nine months ended April 30, 2021.

Earnings Per Share [Abstract]

Net income (loss) per share

Note 2 – Net income (loss) per share

Basic net income (loss) per share represents net income (loss) divided by the weighted average number of common shares outstanding during the period. For the three and nine months ended April 30, 2021, approximately 397,000 and 104,000 weighted average stock options and performance stock units respectively were included in the calculation of diluted weighted average shares outstanding. As a result of the net loss for the three and nine month periods ended April 30, 2020, diluted weighted average shares outstanding are the same as basic weighted average shares outstanding, and do not include the potential common shares from stock options and performance stock units because to do so would be antidilutive. For the three and nine months ended April 30, 2020, approximately 40,000 and 56,000 respectively, of potential common shares (“in the money options”) were excluded from the calculation of diluted earnings per share.

For the three and nine months ended April 30, 2021, the effect of approximately 814,000 and 1,686,000 of outstanding “out of the money” options to purchase common shares were excluded from the calculation of diluted net income per share because their effect would be anti-dilutive. For the three and nine months ended April 30, 2020, the effect of approximately 2,201,000 and 1,805,000 of outstanding “out of the money” options to purchase common shares were excluded from the calculation of diluted net income per share because their effect would be anti-dilutive.

Revenue from Contract with Customer [Abstract]

Revenue Recognition

Note 3 – Revenue Recognition

Clinical Services Revenue

Service revenues in the Company’s clinical services business accounted for approximately 76% of the Company’s total revenues for the three and nine months ended April 30, 2021 and 58% of the Company’s total revenues for the three and nine months ended April 30, 2020, and are primarily comprised of a high volume of relatively low-dollar transactions. The services business, which provides clinical testing services, satisfies its performance obligation and recognizes revenues upon completion of the testing process for a specific patient and reporting to the ordering physician. The Company may also perform clinical testing services for other laboratories and will recognize revenue from those services when reported to the ordering laboratory. The Company estimates the amount of consideration it expects to receive from customer groups using the portfolio approach. These estimates of the expected consideration include the impact of contractual allowances and price concessions on our customer group portfolios consisting of healthcare insurers, government payers, client payers and patients as described below. Contracts with customers in our laboratory services business do not contain a financing component, based on the typically limited period of time between performance of services and collection of consideration. The transaction price includes variable consideration in the form of the contractual allowance and price concessions as well as the collectability of the transaction based on patient intent and ability to pay. The Company uses the expected value method in estimating the amount of the variability included in the transaction price.

The following are descriptions of our laboratory services business portfolios:

Third party payers and Health Maintenance Organizations (HMO’s)

Reimbursements from third party payers, primarily healthcare insurers and HMO’s are based on negotiated fee-for-service schedules and on capitated payment rates. Revenues consist of amounts billed net of contractual allowances for differences between amounts billed and the estimated consideration the Company expects to receive from such payers, which considers historical collection and denial experience and the terms of the Company’s contractual arrangements. Adjustments to the allowances, based on actual receipts from the third-party payers, are recorded upon settlement.

Collection of the consideration the Company expects to receive is normally a function of providing complete and correct billing information to these third party payers within the various filing deadlines, and typically occurs within 30 to 90 days of billing. Provided the Company has billed healthcare insurers accurately with complete information prior to the established filing deadline, there has historically been little to no collection risk. If there has been a delay in billing, the Company determines if the amounts in question will likely go past the filing deadline, and if so, will reserve accordingly for the billing.

Third-party payers, including government programs, may decide to deny payment or recoup payments for testing that they contend was improperly billed or not medically necessary, against their coverage determinations, or for which they believe they have otherwise overpaid (including as a result of their own error), and we may be required to refund payments already received.

Our revenues may be subject to adjustment as a result of these factors among others, including without limitation, differing interpretations of billing and coding guidance and changes by government agencies and payers in interpretations, requirements, and “conditions of participation” in various programs.

Government Payer - Medicare

Reimbursements from Medicare are based on fee-for-service schedules set by Medicare, which is funded by the government. Revenues consist of amounts billed net of contractual allowances for differences between amounts billed and the estimated consideration the Company expects to receive from Medicare, which considers historical collection and denial experience and other factors. Adjustments to the allowances, based on actual receipts from the government payers, are recorded upon settlement.

Collection of consideration the Company expects to receive is normally a function of providing the complete and correct billing information within the various filing deadlines and typically occurs within 60 days of billing. Provided the Company has billed the government payer accurately with complete information prior to the established filing deadline, there has historically been little to no collection risk. If there has been a delay in billing, the Company determines if the amounts in question will likely go past the filing deadline, and, if so, it will reserve accordingly for the billing.

Patient self-pay

Uninsured patients are billed based on established patient fee schedules or fees negotiated with physicians on behalf of their patients. Coinsurance and deductible responsibilities based on fees negotiated with healthcare insurers are also billed to insured patients and included in this portfolio. Collection of billings from patients is subject to credit risk and ability of the patients to pay. Revenues consist of amounts billed net of discounts provided to uninsured patients in accordance with the Company’s policies and implicit price concessions. Implicit price concessions represent differences between amounts billed and the estimated consideration the Company expects to receive from patients, which considers historical collection experience and other factors including current market conditions. Adjustments to the estimated allowances, based on actual receipts from the patients, are recorded upon settlement. Patient responsibility is invoiced and if it reaches 91 days outstanding, the account is sent to a collection agency for further processing. After the account has been with the collection agency for at least 105 days, and is determined to be uncollectable it is written off.

The following table represents clinical services net revenues and percentages by type of customer:

	Three months ended April 30, 2021				Three months ended April 30, 2020

For nine months ended April 30, 2021 and 2020, all of the Company’s clinical services revenues were generated within the United States.

Products Revenue

Products revenues consist of the sale of single-use products used in the identification of genomic information and are recognized at a point in time following the transfer of control of such products to the customer, which generally occurs upon shipment. Payment terms for shipments to end-user and distributor customers may range from 30 to 90 days. Any claims for credit or return of goods may be made generally within 30 days of receipt. Revenues are reduced to reflect estimated credits and returns, although historically these adjustments have not been material. Taxes collected from customers relating to product sales and remitted to governmental authorities are excluded from revenue. Amounts billed to customers for shipping and handling are included in revenue, while the related shipping and handling costs are reflected in cost of products.

Products revenue by geography is as follows:

	Three Months Ended April 30				Nine Months Ended April 30

Long term debt

Note 7 – Long term debt

In connection with the purchase of our new facility in November 2018, a wholly-owned subsidiary (the “mortgagor subsidiary”) of the Company entered into a Fee Mortgage and Security Agreement (the “mortgage agreement”) with Citibank, N.A. (the “mortgagee”). The mortgage agreement provides for a loan of $4,500 for a term of 10 years, bears a fixed interest rate of 5.09% per annum and requires monthly mortgage payments of principal and interest of $30. Debt issuance costs of $72 are being amortized over the life of the mortgage agreement. The balance of unamortized debt issuance cost was $55 at April 30, 2021. At April 30, 2021, the balance owed by the subsidiary under the mortgage agreement was approximately $4.2 million. The Company’s obligations under the mortgage agreement are secured by the new facility and by a $750 cash collateral deposit with the mortgagee as additional security. This restricted cash is included in other assets as of April 30, 2021. We assumed from the seller an operating lease for a tenant at the facility which expired on June 30, 2020. Rental income from the assumed lease for the three and nine months ended April 30, 2020 is included in Other income.

The mortgage agreement includes affirmative and negative covenants and events of default, as defined. Events of default include non-payment of principal and interest on debt outstanding, non-performance of covenants, material changes in business, breach of representations, bankruptcy or insolvency, and changes in control. The mortgage includes certain financial and liquidity covenants. As of April 30, 2021, the Company was in compliance with those covenants. The liquidity covenant requires that we own and maintain at all times and throughout the remaining term of the loan at least $25 million of liquid assets, defined as time deposits, money market accounts, commercial paper and obligations issued by the U.S. government or any of its agencies.

In April 2020, our subsidiary in Switzerland received a loan of CHF 0.4 million ($0.4 million, based on the foreign exchange rate as of April 30, 2021) from the Swiss government under the “Corona Krise” emergency loan program in response to the pandemic. This loan is uncollateralized, bears 0% interest, is due in 5 years, and may be repaid at any time. This loan is included in long term debt – net as of April 30, 2021.

The CARES Act expanded the U.S. Small Business Administration’s (SBA) business loan program to create the Paycheck Protection Program (PPP), which provides employers with uncollateralized loans whose primary purpose is to retain or maintain workforce and salaries for a twenty four week period (“covered period”) following receipt of the loan. Currently, PPP loans have a 1% fixed interest rate and are due from two to five years. The primary features of the PPP loan program are to provide funding to companies to cover eligible expenses, and the potential for forgiveness of that portion of the loan spent on payroll and other permitted operating expenses during the covered period, subject to reductions if the borrower fails to maintain or restore employee and salary levels. We applied for the PPP loan based on the eligibility and need requirements established when the program was announced and in April 2020 received $7,000 through Citibank N.A., the Company’s existing lender, pursuant to the PPP.

The PPP Loan matures on April 17, 2022 (the “Maturity Date”), accrues interest at 1% per annum and may be prepaid in whole or in part without penalty. No interest payments are due within the initial six months of the PPP Loan. Interest accrued during the initial six-month period is due and payable, together with the principal, on the Maturity Date. The Company used all proceeds from the PPP Loan to retain employees, maintain payroll and make lease and utility payments to support business continuity throughout the COVID-19 pandemic. All or a portion of the PPP Loan, including interest, could be forgiven by the SBA by applying for forgiveness and providing acceptable documentation that demonstrates the funds were used as required by the terms of forgiveness and in accordance with the SBA’s requirements. Due to complexities with respect to loan forgiveness calculations and government pronouncements with respect to expenditure eligibility, we did not recognize any loan forgiveness as of April 30, 2021 and have classified the loan as other short term debt as the loan matures in less than one year. We expect to earn loan forgiveness on all of the loan proceeds and have accrued no interest. The SBA intends to audit loans in excess of $2.0 million. The SBA also required businesses that received loans in excess of $2 million to complete a loan necessity questionnaire to evaluate the good faith certification made on their PPP applications that economic uncertainty made their loan request necessary to support ongoing operations. In April 2021 we submitted our PPP loan forgiveness application and the loan necessity questionnaire to the SBA through Citibank N.A., our intermediary lending bank. According to the SBA, its review may take up to 90 calendar days from the receipt of the loan forgiveness application and loan necessity questionnaire. No assurance can be given that we will obtain forgiveness of the PPP loan in whole or in part by July 31, 2021.

Minimum future annual principal payments under these agreements as of April 30, 2021 are as follows:

July 31,	Total

Leases

Leases Disclosure [Abstract]

Leases

Note 8 - Leases

The Company follows ASU No. 2016-02 “Leases (Topic 842)”, which requires leases with durations greater than twelve months to be recognized on the balance sheet.

The Company determines if an arrangement is or contains a lease at contract inception. The Company leases buildings, office space, patient service centers, and equipment primarily through operating leases, and equipment through a limited number of finance leases. Generally, a right-of-use asset, representing the right to use the underlying asset during the lease term, and a lease liability, representing the payment obligation arising from the lease, are recognized on the balance sheet at lease commencement based on the present value of the payment obligation. For operating leases, expense is recognized on a straight-line basis over the lease term. For finance leases, interest expense on the lease liability is recognized using the effective interest method and amortization of the right-of-use asset is recognized on a straight-line basis over the shorter of the estimated useful life of the asset or the lease term. Short-term leases with an initial term of 12 months or less are not recorded on the balance sheet; the Company recognizes lease expense for these leases on a straight-line basis over the lease term.

The Company primarily uses its incremental borrowing rate in determining the present value of lease payments as the Company’s leases generally do not provide an implicit rate.

The Company has lease agreements with (i) right-of-use asset payments and (ii) non-lease components (i.e. payments related to maintenance fees, utilities, etc.), which have generally been combined and accounted for as a single lease component.

The Company’s leases have remaining terms of less than 1 year to 8 years, some of which include options to extend the leases for up to 5 years. The Company’s lease terms may include renewal options that are reasonably certain to be exercised and termination options that are reasonably certain not to be exercised.

Certain of the Company’s lease agreements include rental payments adjusted periodically for inflation or a market rate which are included in the lease liabilities.

Accrued Liabilities

Note 9 – Accrued Liabilities

At April 30, accrued liabilities consist of:

	April 30, 2021		July 31, 2020
Payroll, benefits, and commissions	$	4,273	$	5,227
Professional fees		627		710

Other		2,305		1,723
	$	12,528	$	12,833

Deferred revenue

In order to increase cash flow to providers of services and suppliers impacted by the pandemic, the Centers for Medicare and Medicaid Services (CMS) expanded its Accelerated and Advance Payment Program to a broader group of Medicare providers. We applied for and received a $2,526 payment advance from this program in April 2020. The recoupment by CMS of our advance payment had been scheduled to begin 120 days after the date of receipt, at which time every claim we submit from that point would be automatically offset to repay the advance payment.

In October 2020, the Continuing Appropriations Act, 2021 and Other Extensions Act amended the repayment terms of the Advance Payment Program. The recoupment period was extended and the automatic recoupment begins one year after the date the advance payment was received. CMS began recoupment of our advance in April 2021. During the next 11 months, the recoupment rate will be 25% of claims processed and repayment occurs through an automatic recoupment of our Medicare payments. If the total amount of the advance payment is not recovered within 29 months from the date the advance was received, a demand letter for the outstanding balance will be issued. We expect the entire balance of the payment advance to be recouped by the end of the 11 month period and include the remaining balance in accrued liabilities at April 30, 2021.

Self-Insured Medical Plan

The Company self-funds medical insurance coverage for certain of its U.S. based employees. The risk to the Company is believed to be limited through the use of individual and aggregate stop loss insurance. As of April 30, 2021, the Company has established a reserve of $243, which is included in accrued liabilities, for claims that have been reported but not paid and for claims that have been incurred but not reported. The reserve is based upon the Company’s historical payment trends, claim history and current estimates.

Stockholders' Equity Note [Abstract]

Stockholders’ Equity

Note 10 – Stockholders’ Equity

Controlled Equity Offering

The Company has a Controlled Equity Offering^SM Sales Agreement (the “Sales Agreement”) with Cantor Fitzgerald & Co., as sales agent (“Cantor”). Under the Sales Agreement, the Company may offer and sell, from time to time, through Cantor, shares of the Company’s common stock, par value $0.01 per share (the “Common Stock”). The Company pays Cantor a commission of 3.0% of the aggregate gross proceeds received under the Sale Agreement. The Company is not obligated to make any sales of the Shares under the Sales Agreement. The offering of Shares pursuant to the Sales Agreement will terminate upon the earlier of (a) the sale of all of the Shares subject to the Sales Agreement or (b) the termination of the Sales Agreement by Cantor or the Company, as permitted therein. The initial agreement contemplated the sale of shares of the Company’s common stock having an aggregate offering price of up to $20.0 million. In December 2014, the Sales Agreement was amended in order for the Company to offer and sell additional shares of Common Stock having an aggregate offering price of $20.0 million.

In September 2017, the Company filed with the SEC a Form S-3 “shelf” registration and sales agreement prospectus covering the offering, issuance and sale of our Common Stock that may be issued and sold under the existing Sales Agreement in an aggregate amount of up to $19.2 million. A total of $150 million of securities may be sold under this shelf registration, which was declared effective September 2017. The Form S-3 expired in October 2020 but may be refiled at any time at the discretion of the Company.

During the nine months ended April 30, 2021 and 2020, the Company did not sell any shares of Common Stock under the Sales Agreement.

Share-based compensation

In January 2011, the Company’s stockholders approved the adoption of the 2011 Incentive Plan (the “2011 Plan”) for the issuance of equity awards, including, among others, options, restricted stock, restricted stock units and performance stock units for up to 3,000,000 shares of common stock. On January 5, 2018, the Company’s stockholders approved the amendment and restatement of the 2011 Plan (the “Amended and Restated 2011 Plan”) to increase the number of shares of common stock available for grant under the 2011 Plan by 2,000,000 shares of common stock bringing the total number of shares available for grant to 5,000,000 shares of common stock. On October 7, 2020, the Company’s Board of Directors approved the amendment and restatement of the Amended and Restated 2011 Plan, with an effective date of October 7, 2020 and subject to approval by the Company’s stockholders at the 2020 annual meeting of stockholders of the Company. The amendment and restatement of the Amended and Restated 2011 Plan was for purposes of, among other things, (i) increasing the shares of common stock available for grant under the Amended and Restated 2011 Plan by an additional 4,000,000 shares of common stock bringing the total number of shares available for grant to 9,000,000 shares of common stock and (ii) extending the term of the Amended and Restated 2011 Plan until October 7, 2030. In January 2021, the Company’s stockholders approved the amendment and restatement of the Amended and Restated 2011 Plan.

The exercise price of options granted under the Amended and Restated 2011 Plan, as amended and restated, is equal to or greater than fair market value of the common stock on the date of grant. The Amended and Restated 2011 Plan, as amended and restated, will terminate at the earliest of (a) such time as no shares of common stock remain available for issuance under the plan, (b) termination of the plan by the Company’s Board of Directors, or (c) October 7, 2030. Awards outstanding upon expiration of the Amended and Restated 2011 Plan, as amended and restated, will remain in effect until they have been exercised or terminated, or have expired. As of April 30, 2021, there were approximately 4,834,000 shares of common stock available for grant under the Amended and Restated 2011 Plan, as amended and restated.

The amounts of share-based compensation expense recognized in the periods presented are as follows:

	Three months ended April 30,				Nine months ended April 30,
	2021		2020		2021		2020
Stock options and performance stock units	$	297	$	206	$	638	$	724
Restricted stock		—		1		2		4
	$	297	$	207	$	640	$	728

The following table sets forth the amount of expense related to share-based payment arrangements included in specific line items in the accompanying statements of operations:

	Three months ended April 30,				Nine months ended April 30,
	2021		2020		2021		2020

Cost of revenues		39		—		66		—
	$	297	$	207	$	640	$	728

No excess tax benefits were recognized during the nine month periods ended April 30, 2021 and 2020.

Stock Option Plans

The following table summarizes stock option activity during the nine month period ended April 30, 2021:

	Options			Weighted Average Exercise Price		Weighted Average Remaining Contractual Term		Aggregate Intrinsic Value (000s)
Outstanding at July 31, 2020		2,636,496		$	4.05
Awarded		543,104		$	2.57
Exercised		(34,667	)		2.80			$
Expired or forfeited		(619,371	)	$	3.40
Outstanding at end of period		2,525,562		$	3.76		2.6 years	$	957
Exercisable at end of period		1,581,326		$			1.6 years	$

As of April 30, 2021, the total future compensation cost related to non-vested options, not yet recognized in the statements of operations, was $916 and the weighted average period over which the remaining expense of these awards is expected to be recognized is approximately sixteen months.

The intrinsic value of in the money stock option awards at the end of the period represents the Company’s closing stock price on the last trading day of the period in excess of the exercise price multiplied by the number of options.

Performance Stock Units

To better align the long-term interest of executives with growing U.S. practices, beginning in fiscal 2018, the Company’s board of directors approved long-term incentive awards in the form of performance-based stock units (“Performance Stock Units” or “PSUs”) in addition to time based stock options. The PSUs earned will be determined over a three fiscal year performance period. The primary performance metrics will be revenue and Adjusted EBITDA growth. Payouts based on revenue and adjusted EBITDA goals will be modified based on Total Shareholder Return (“TSR”) performance relative to Enzo’s peer group.

During the fiscal years ended 2020, 2019 and 2018, the Company’s board of directors approved the award of PSUs to its executive officers, whose established grant dates are in the table below. These awards provide for the grant of shares of our common stock at the end of a three–year period based on the achievement of average revenue growth and adjusted EBITDA growth over that period.

During the nine months ended April 30, 2021, one former executive forfeited a total of 6,000 PSUs. During the nine months ended April 30, 2020, one former executive forfeited a total of 14,500 PSUs. During both the three and nine months ended April 30, 2021 and 2020, the Company recorded $162 and $0, respectively as compensation expense for the outstanding PSU’s. There were no PSU awards approved by the Company’s board of directors through the nine months ended April 30, 2021.

The following table summarizes PSU’s granted and outstanding as of April 30, 2021:

Grant Date	Total Grant		Forfeitures			Outstanding		Fair Market Value At Grant Date (000s)
10/15/2018		32,000		(6,000	)		26,000	$	107
10/15/2019		80,500		(14,500	)		66,000	$	222

Segment Reporting [Abstract]

Segment reporting

Note 11 – Segment reporting

The Company has three reportable segments: Products, Clinical Services and Therapeutics. The Company’s Products segment develops, manufactures, and markets products to research and pharmaceutical customers. The Clinical Services segment provides diagnostic services to the health care community. The Company’s Therapeutics segment conducts research and development activities for therapeutic drug candidates. The Company evaluates segment performance based on segment income (loss) before taxes. Costs excluded from segment income (loss) before taxes and reported as “Other” consist of corporate general and administrative costs which are not allocable to the three reportable segments. All intersegment activities are eliminated.

Legal and related expenses incurred to defend the Company’s intellectual property, which may result in settlements recognized in another segment and other general corporate matters are considered a component of the Other segment. Legal and related expenses specific to other segments’ activities are allocated to those segments.

Legal settlements, net, represent activities for which royalties would have been received in the Company’s Products segment. Management of the Company assesses assets on a consolidated basis only and therefore, assets by reportable segment have not been included in the reportable segments below. The accounting policies of the reportable segments are the same as those described in the summary of significant accounting policies.

The following financial information represents the operating results of the reportable segments of the Company:

Commitments and Contingencies Disclosure [Abstract]

Contingencies

Note 12 Contingencies

The Company has brought cases in the United States District Court for the District of Delaware (“the Court”), alleging patent infringement against various companies. In 2017, the Court ruled that the asserted claims of the ‘180 and ‘405 Patents are invalid for nonenablement in cases involving Abbott, Becton Dickinson, Gen-Probe, Hologic, and Roche. That ruling was affirmed by the United States Court of Appeals for the Federal Circuit (“Federal Circuit”) in June 2019. Enzo subsequently filed a petition for certiorari regarding the invalidity ruling for the ‘180 and ‘405 Patents in February 2020; the Supreme Court denied Enzo’s petition on March 30, 2020. There are currently two cases that were originally brought by the Company in the Court. In those two cases, Enzo alleges patent infringement against Becton Dickinson Defendants and Roche Defendants, respectively. The claims in those cases involve the ‘197 Patent. Both cases are stayed.

In separate inter partes review proceedings before the U.S. Patent and Trademark Office involving, among others, Becton Dickinson, certain claims of the ‘197 Patent were found unpatentable as anticipated or obvious and cancelled by the Patent Trial and Appeals Board (“Board”). Enzo appealed that decision to the Federal Circuit. On August 16, 2019, the Federal Circuit affirmed the Board’s decision, finding that each of the challenged claims is unpatentable. The Company filed a petition for rehearing and rehearing en banc on October 30, 2019, which the Federal Circuit denied on December 4, 2019. The Company filed a petition for certiorari with the Supreme Court on March 3, 2020, which was denied.

In April 2019, the Company entered into an agreement with Hologic and Grifols, resolving litigation resulting from four cases originally brought by the Company in the Court. As a result, Enzo dismissed (1) a stayed patent litigation regarding the ‘180 and ‘197 Patent against Hologic in the Court; (2) the Consolidated Appeals against Gen-Probe and Hologic resulting from two cases filed in the Court, and (3) the Company’s appeal in the litigation involving the ‘581 Patent that involved both Hologic and Grifols. As a result of the agreement with Hologic, Hologic withdrew from Enzo’s Federal Circuit appeal of the Board’s adverse rulings in the inter partes review proceedings regarding the ‘197 Patent filed by Hologic and joined by Becton Dickinson mentioned above.

On February 5, 2020, Harbert Discovery Fund, LP and Harbert Discovery Co-Investment Fund I, LP (“Plaintiffs”) brought an action in the United States District Court for the Southern District of New York against the Company and five of its present or former Directors, Dr. Elazar Rabbani, Barry W. Weiner, Dr. Bruce A. Hanna, Dov Perlysky and Rebecca Fischer. On March 26, 2020, Plaintiffs filed an amended complaint against the same defendants. Count I asserted the Company violated Section 14(a) of the Securities and Exchange Act of 1934 and Rule 14a-9 thereunder by disseminating proxy materials that made two purportedly false statements: (a) a “January 28, 2020 Enzo press release [that purportedly] falsely stated that the Annual Meeting would be ‘delayed’ by action of the Board to February 25, 2020 when, in fact, the Annual Meeting would convene as planned on January 31, 2020”, and (b) a “January 31 Enzo Proxy [that purportedly] falsely stated that the Proposed By-Law Amendment [to Article II, Section 9] would be approved if it received…a majority of the votes….rather than the required Supermajority Vote as provided for in the Charter. “Count II asserted a claim against the individual defendants under Section 20(a) of the Exchange Act premised on Enzo’s purported violation of Section 14(a) and Rule 14a-9. Count III asserted the individual defendants breached their fiduciary duty, based on the same conduct and by seeking to entrench themselves. Finally, Count IV purported to assert a derivative claim for a declaration that any amendment to Article II, Section 2 requires the approval of 80% of Enzo’s shareholders. On July 16, 2020, the day before the defendants’ motion to dismiss was due, plaintiffs asked the Court to dismiss their claims without prejudice. Defendants asked plaintiffs to dismiss the claims with prejudice, but they refused. On July 17, 2020, the Court dismissed the claims without prejudice. If plaintiffs reassert the claims, defendants intend to vigorously defend against them.

On November 27, 2020, the Company brought an action in the United States District Court for the Southern District of New York against Harbert Discovery Fund, LP, Harbert Discovery Co-Investment Fund I, LP, Harbert Fund Advisors, Inc., Harbert Management Corp. and Kenan Lucas. The Company alleges the defendants made false and misleading representations, or omitted to state material facts necessary to make their statements not misleading, in proxy materials they disseminated seeking the election to the Company’s Board of Directors at its 2019 Annual Meeting of two candidates they nominated, in violation of Section 14(a) of the 1934 Exchange Act and Rule 14a-9 thereunder. The Company seeks damages and injunctive relief. On February 15, 2021, Defendants filed a motion to dismiss. On March 8, 2021, the Company filed its opposition to that motion. On March 18, 2021 defendants filed their reply in further support of the motion. The motion is sub judice.

There can be no assurance that the Company will be successful in any of these litigations. Even if the Company is not successful, management does not believe that there will be a significant adverse monetary impact on the Company. The Company is party to other claims, legal actions, complaints, and contractual disputes that arise in the ordinary course of business. The Company believes that any liability that may ultimately result from the resolution of these matters will not, individually or in the aggregate, have a material adverse effect on its financial position or results of operations.

As described in Note 3, third-party payers, including government programs, may decide to deny payment or recoup payments for testing that they contend was improperly billed or not medically necessary, against their coverage determinations, or for which they believe they have otherwise overpaid (including as a result of their own error), and we may be required to refund payments already received. During the third fiscal quarter of 2019, a significant third-party payer informed us outside of their typical business practice that they believe it overpaid the Company during certain periods of fiscal 2018. The Company disputed these claims and formally sent legal appeal letters to the payer.

During the fiscal 2020 period, we recorded $0.8 million in legal and related expenses as a result of reduced reimbursements this payer made to us. In April 2020, we and the payer entered into a settlement agreement and release whereby the parties agreed that the $0.8 million previously withheld by the payer shall fully and completely satisfy the dispute.

Accounting Policies [Abstract]

Use of Estimates

Use of Estimates

The preparation of financial statements in conformity with accounting principles generally accepted in the United States (“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 financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

COVID 19 [Policy Text Block]

COVID 19

The extent to which the COVID-19 pandemic impacts the Company’s business and financial results will depend on numerous evolving factors including, but not limited to: the magnitude and duration of the COVID-19 pandemic, the extent to which it will impact worldwide macroeconomic conditions including, but not limited to, employment rates and health insurance coverage, the speed of the anticipated recovery, and governmental and business reactions to the pandemic. The Company assessed certain accounting matters that generally require consideration of forecasted financial information in context with the information reasonably available to the Company and the unknown future impacts of COVID-19 as of April 30, 2021 and through the date of this report. The accounting matters assessed included, but were not limited to, the Company’s patient self-pay revenue concessions and credit losses in the Clinical Services segment, accounts receivable, inventories and the carrying value of goodwill and other long-lived assets. The Company’s future assessment of the magnitude and duration of COVID-19, as well as other factors, could result in additional material impacts to the Company’s consolidated financial statements in future reporting periods. We fully expect COVID-19 volume to decline in the quarters ahead as the percentage of Americans who are vaccinated increases.

Effect of New Accounting Pronouncements

Effect of New Accounting Pronouncements

Pronouncements Issued but Not Yet Adopted

In June 2016, FASB issued ASU No. 2016-13 Financial Instruments – Credit Losses (Topic 326). This standard, as amended, changes the impairment model for most financial instruments, including trade receivables, from an incurred loss method to a new forward-looking approach, based on expected losses. The estimate of expected credit losses will require entities to incorporate considerations of historical information, current information and reasonable and supportable forecasts. Adoption of this standard is required for our annual and interim periods beginning August 1, 2023 as long as we continue to qualify as a smaller reporting company at the end of fiscal 2022, and must be adopted using a modified retrospective transition approach. We are currently assessing the impact of the adoption of this standard on our results of operations, financial position and cash flows.

In December 2019, the FASB issued ASU No. 2019-12 Income Taxes (Topic 740) Simplifying the Accounting for Income Taxes. The amendments in the ASU simplify the accounting for income taxes by removing certain exceptions to the general principles of Topic 740. The amendments also improve consistent application of and simplify U.S. GAAP for other areas of Topic 740 by clarifying and amending existing guidance. The amendments in this ASU are required for our annual and interim periods beginning August 1, 2021. The adoption of the amendments in this ASU is not expected to have a material impact on our consolidated results of operations, financial position or cash flows

We reviewed all other recently issued accounting pronouncements and have concluded they are not applicable or not expected to be significant to the accounting for our operations.

Concentration Risk

Concentration Risk

Other than the Medicare program, two providers whose programs are included in the “Third-party payers” and “Health Maintenance Organizations” (“HMO’s”) categories represent approximately 36% and 35% of Clinical Services net revenue for the three and nine month periods ended April 30, 2021. Other than the Medicare program, one provider whose programs are included in those categories represents approximately 21% of Clinical Services net revenue for both the three and nine month periods ended April 30, 2020. As of April 30, 2021, the Medicare program represents 15%, a provider in the third party category represents 13%, and a government payer in the patient self-pay category represents 10% of Clinical Services net receivables.

Income Taxes

Income Taxes

The Company accounts for income taxes under the liability method of accounting for income taxes. Under the liability method, 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. The liability method requires that any tax benefits recognized for net operating loss carry forwards and other items be reduced by a valuation allowance where it is not more likely than not the benefits will be realized in the foreseeable future. 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. Under the liability method, 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. It is the Company’s policy to provide for uncertain tax positions, if any, and the related interest and penalties based upon management’s assessment of whether a tax benefit is more likely than not to be sustained upon examination by tax authorities. To the extent the Company prevails in matters for which a liability for an unrecognized tax benefit is established or is required to pay amounts in excess of the liability, the Company’s effective tax rate in a given financial statement period may be affected.

Due to our tax net operating loss carryforwards, we do not provide for an income tax provision on pre-tax income in the fiscal 2021 periods. We maintain a full valuation allowance on all tax assets and, as a consequence, do not provide any tax benefit for the fiscal 2020 period losses.

Fair Value Measurements

Fair Value Measurements

The Company determines fair value measurements used in its consolidated financial statements based upon the exit price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants exclusive of any transaction costs, as determined by either the principal market or the most advantageous market. Inputs used in the valuation techniques to derive fair values are classified based on a three-level hierarchy. The basis for fair value measurements for each level within the hierarchy is described below with Level 1 having the highest priority and Level 3 having the lowest.

Level 1 Quoted prices in active markets for identical assets or liabilities.

Level 2 Quoted prices for similar assets or liabilities in active markets; quoted prices for identical or similar instruments in markets that are not active; and model-derived valuations in which all significant inputs are observable in active markets.

Level 3 Valuations derived from valuation techniques in which one or more significant inputs are unobservable.

Marketable securities

Marketable securities

The Company limits its credit risk associated with investments by investing in a mutual fund and an exchange traded fund (ETF) which hold highly rated corporate bonds, asset backed securities, municipal bonds, mortgage obligations and government obligations. These investments are classified as trading securities and are Level 1 fair value investments. As of April 30, 2021, the fair value of these investments was $29,932 and the cost basis was $30,023. We recognized unrealized losses of $91 for the three and nine months ended April 30, 2021.
