**NOTES TO CONSOLIDATED FINANCIAL STATEMENTS**

**As of April 30, 2025**

**(unaudited)**

**(Dollars in thousands except share data)**

**Note 1 – Basis of Presentation**

Enzo Biochem, Inc. (the "Company", "we", "our" or "Enzo") has operated as a life sciences company for over 45 years. The primary business of Enzo today is conducted through its Enzo Life Sciences division ("Enzo Life Sciences"), which focuses on labeling and detection technologies from DNA to whole cell analysis, including a comprehensive portfolio of thousands of high-quality products, including antibodies, genomic probes, assays, biochemicals, and proteins. The Company's proprietary products and technologies play central roles in translational research and drug development areas, including cell biology, genomics, assays, immunohistochemistry, and small molecule chemistry. Enzo strives to enable a healthier world using scientific innovation through drug discovery, development and diagnostic solutions.

The accompanying consolidated financial statements include the accounts of Enzo Biochem, Inc. and its wholly-owned subsidiaries, Enzo Life Sciences, Inc. ("Enzo Life Sciences"), Enzo Therapeutics, Inc. ("Enzo Therapeutics"), Enzo Realty LLC ("Enzo Realty"), and Enzo Realty II LLC ("Enzo Realty II"), collectively or with one or more of its subsidiaries referred to as the "Company" or "Companies." The financial statements also include as discontinued operations the accounts of its wholly-owned subsidiary Enzo Clinical Labs, Inc. ("Enzo Clinical Labs"). Effective July 24, 2023, we completed the sale of certain assets used in our clinical services operations to Laboratory Corporation of America Holdings, a Delaware corporation ("Labcorp"), and thereby exited the clinical services business. See Note 2.

The consolidated balance sheet as of April 30, 2025, the consolidated statements of operations, comprehensive loss and stockholders' equity for the three and nine months ended April 30, 2025 and 2024, and the consolidated statements of cash flows for the nine months ended April 30, 2025 and 2024 (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 of America ("U.S. GAAP"), 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, 2024 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, 2024 has been derived from the audited financial statements at that date. The results of operations for the three and nine months ended April 30, 2025 are not necessarily indicative of the results that may be expected for the fiscal year ending July 31, 2025. We have one reportable segment, Products.

*Principles of consolidation*

The accompanying consolidated financial statements have been prepared in conformity with U.S. GAAP and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions and balances have been eliminated.

*Use of Estimates*

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.

*Contingencies*

 

Contingencies are evaluated and a liability is recorded when the matter is both probable and reasonably estimable. Gain contingencies are evaluated and not recognized until the gain is realizable or realized.

 

*Foreign Currency Translation/Transactions*

The Company has determined that the functional currency for its foreign subsidiaries is the local currency. For financial reporting purposes, assets and liabilities denominated in foreign currencies are translated at current exchange rates and profit and loss accounts are translated at weighted average exchange rates. Resulting foreign currency translation adjustments are recognized as other comprehensive income (loss) in the consolidated statements of comprehensive loss and are included as a separate component of stockholders' equity as accumulated other comprehensive income. Gains or losses resulting from transactions entered into in other than the functional currency are recorded as foreign exchange gains and losses in the consolidated statements of operations.

*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.

*Cash and cash equivalents*

Cash and cash equivalents consist of demand deposits with banks and highly liquid money market funds. At April 30, 2025 and July 31, 2024, the Company had cash and cash equivalents in foreign bank accounts of $484 and $391, respectively.

*Concentration of Credit Risk*

Financial instruments that potentially subject the Company to concentrations of credit risk primarily consist of cash and cash equivalents and accounts receivable. The Company believes the fair value of the aforementioned financial instruments approximates the cost due to the immediate or short-term nature of these items. At April 30, 2025 and July 31, 2024, the Company had cash deposited in certain financial institutions in excess of federally insured levels. The Company regularly monitors the financial stability of these financial institutions and believes that it is not exposed to any significant credit risk in cash and cash equivalents or restricted cash.

Concentration of credit risk with respect to the Company's Products segment is mitigated by the diversity of the Company's customers and their dispersion across many different geographic regions. To reduce risk, the Company routinely assesses the financial strength of these customers and, consequently, believes that its accounts receivable credit exposure with respect to these customers is limited.

*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 when it is more likely than not that the benefits may not be realized. 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.

The Company carries a valuation allowance equal to domestic and foreign net deferred tax assets as of April 30, 2025 and July 31, 2024. The Company believes that the valuation allowance is necessary as it is not more likely than not that the deferred tax assets will not be realized in the foreseeable future based on positive and negative evidence available at this time. This conclusion was reached because of uncertainties relating to future taxable income, in terms of both its timing and its sufficiency, which would enable the Company to realize the deferred tax assets.

*Effect of New Accounting Pronouncements* 

Pronouncements Issued but Not Yet Adopted

In December 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) 2023-09, *Income Taxes (Topic 740): Improvements to Income Tax Disclosures*. The amended guidance enhances income tax disclosures primarily related to the effective tax rate reconciliation and income taxes paid information. This guidance requires disclosure of specific categories in the effective tax rate reconciliation and further information on reconciling items meeting a quantitative threshold. In addition, the amended guidance requires disaggregating income taxes paid (net of refunds received) by federal, state, and foreign taxes. It also requires disaggregating individual jurisdictions in which income taxes paid (net of refunds received) is equal to or greater than five percent of total income taxes paid (net of refunds received). The amended guidance will be effective for our fiscal year beginning August 1, 2025. The guidance can be applied either prospectively or retrospectively. We are currently in the process of evaluating the impact this amended guidance may have on the footnotes to our consolidated financial statements.

 

In November 2023, FASB issued ASU No. 2023-07, *Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures* (ASU 2023-07), which requires an enhanced disclosure of significant segment expenses on an annual and interim basis. This guidance will be effective for our annual period ending July 31, 2025 and our interim periods beginning August 1, 2025. Upon adoption, we expect the guidance will be applied retrospectively to all prior periods presented in the consolidated financial statements. We do not expect the adoption of this guidance to have a material impact on our consolidated financial statements.

 

In November 2024, FASB issued ASU No. 2024-03, *Disaggregation on Income Statement Expenses (DISE),* which specifies additional disclosure requirements. The new guidance requires additional disclosures, including the composition of certain expense line items (such as purchases of inventory, employee compensation, and "other expenses") and a separate disclosure for selling expenses. This guidance will be effective for our annual period ending July 31, 2028 and our interim periods beginning August 1, 2028. Early adoption is permitted. We are currently evaluating the impact that the adoption of ASU 2024-03 will have on our consolidated financial statement disclosures.

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.

**Note 2 – Discontinued operations**

Prior to July 24, 2023, we operated a clinical laboratory, doing business as Enzo Clinical Labs, which provided reference, molecular and esoteric diagnostic medical testing services in the New York, New Jersey, and Connecticut medical communities. Effective July 24, 2023, we completed the sale of certain assets used in the operation of Enzo Clinical Labs and the assignment of certain clinical lab liabilities to Labcorp for an aggregate purchase price of $113.25 million in cash. In accordance with the sale, we ceased our clinical services operations. Excluded from the sale of the clinical services assets were its cash and accounts receivable. As a consequence of the sale, we have classified as discontinued operations all income and expenses attributable to the clinical services business for the fiscal year 2025 and 2024 periods presented.

The following table sets forth the condensed operating results of the discontinued operations for the three and nine months ended April 30:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Three Months Ended<br> April 30** | **Three Months Ended<br> April 30** | **Nine Months Ended<br> April 30** | **Nine Months Ended<br> April 30** |
|  | **2025** | **2024** | **2025** | **2024** |
| General and administrative expense | $270 | $835 | $740 | $3085 |
| Other expense – net | 146 | 54 | 268 | 943 |
| Loss from discontinued operations | $(416) | $(889) | $(1008) | $(4028) |

---

The following table sets forth the condensed carrying amounts of major classes of assets and liabilities of the discontinued operations as of the dates indicated:

---

| | | |
|:---|:---|:---|
|  | **April 30, <br> 2025** | **July 31, <br> 2024** |
| <u>Carrying amounts of major current assets included as part of discontinued operations:</u> |  |  |
| Prepaid and other current | $34 | $182 |
| <u>Carrying amounts of major current liabilities included as part of discontinued operations:</u> |  |  |
| Accrued liabilities and trade payables | 7429 | 14979 |
| Operating lease liabilities and other | 2097 | 1990 |
| Total current liabilities | 9526 | 16969 |
| Current liabilities of discontinued operations, net | $9492 | $16787 |
| <u>Carrying amount of major non-current assets included as part of discontinued operations:</u> |  |  |
| Right-of-use assets | $945 | $1308 |
| Other | 62 | 75 |
| Total non-current assets | 1007 | 1383 |
| <u>Carrying amount of major non-current liabilities included as part of discontinued operations:</u> |  |  |
| Operating lease liabilities and other | 2065 | 3649 |
| Non-current liabilities of discontinued operations, net | $1058 | $2266 |

---

During the nine months ended April 30, 2025, the cash used in operating activities of the discontinued operations was $8,397, primarily for reductions of trade payables and accrued liabilities, and the period loss. During the nine months ended April 30, 2024, the cash used in operating activities of the discontinued operations was $14,219, primarily for reductions of trade payables and accrued liabilities, and the period loss.

**Note 3 – Net loss per share**

Basic net loss per share represents net loss divided by the weighted average number of common shares outstanding during the period. The dilutive effect of potential common shares, consisting of outstanding stock options, and unvested restricted stock units and performance stock units, is determined using the treasury stock method. As a result of the net loss for the three and nine months ended April 30, 2025 and 2024, 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, restricted stock units, or warrants because to do so would be anti-dilutive.

For the three and nine months ended April 30, 2025, the effect of approximately 1,611,000 and 1,838,000, respectively, of outstanding "out of the money" options to purchase common shares and the effect of approximately 529,000 outstanding restricted stock units at April 30, 2025 were excluded from the calculation of diluted net (loss) per share because their effect would be anti-dilutive.

For the three and nine months ended April 30, 2025, the effect of an assumed exercise of 1,000,000 "out of the money" warrants and the hypothetical shares which would be bought back was excluded from the calculation of diluted weighted average shares outstanding because the effect would also be anti-dilutive.

For the three and nine months ended April 30, 2024, the effect of approximately 1,832,000 and 2,542,000, respectively, of outstanding "out of the money" options to purchase common shares and the effect of approximately 77,000 and 133,000, respectively, of outstanding restricted stock units were excluded from the calculation of diluted net (loss) income per share because their effect would be anti-dilutive. During the three and nine months ended April 30, 2024, the effect of approximately 848,000 and 688,000, respectively, of shares related to warrants and the effect of approximately 1,688,000 and 1,438,000, respectively of shares related to the assumed conversion of debentures were excluded from the calculation of diluted weighted average shares outstanding because their effect would be anti-dilutive.

The warrants relate to the convertible debentures, which were repaid in May 2024. The warrants are eligible for any dividends paid on the common stock and are therefore considered to be participating securities which do not have any contractual obligation to share in the Company's losses. The impact on net loss per share under the two-class method was not material for any period presented.

**Note 4 – Revenue Recognition**

<u>Products Revenue</u>

The Company generates revenue from the sale of our single-use products used in the identification of genomic information. Revenue is recorded net of sales tax. The Company considers revenue to be earned when all of the following criteria are met: the Company has a contract with a customer that creates enforceable rights and obligations; promised products are identified; the transaction price is determinable; and the Company has transferred control of the promised items to the customer. A performance obligation is a promise in a contract to transfer a distinct good or service to the customer, and is the unit of account in the contract. The transaction price for the contract is measured as the amount of consideration the Company expects to receive in exchange for the goods expected to be transferred. A contract's transaction price is allocated to each distinct performance obligation and recognized as revenue when, or as, control of the distinct good or service is transferred. Transfer of control for the Company's products is generally at shipment or delivery, depending on contractual terms, but occurs when title and risk of loss transfers to the customer which represents the point in time when the customer obtains the use of and substantially all of the remaining benefit of the product. As such, the Company's performance obligation related to product sales is satisfied at a point in time. The Company recognizes a receivable when it has an unconditional right to payment, which represents the amount the Company expects to collect in a transaction and is most often equal to the transaction price in the contract. Payment terms for shipments to end-user and distributor customers may range from 30 to 90 days. Amounts billed to customers for shipping and handling are included in revenue, while the related shipping and handling costs are reflected in cost of revenues.

Products revenue by geography is as follows:

---

| United States | $4054 | $4793 | $12646 | $14594 |
| Europe | 1706 | 2359 | 5082 | 6783 |
| Asia Pacific | 642 | 870 | 2220 | 3004 |
| Products revenue | $6402 | $8022 | $19948 | $24381 |

**Note 7 – Convertible debentures**

In May 2023, the Company consummated a Securities Purchase Agreement (the "Purchase Agreement") with the Purchasers, as defined in the Purchase Agreement, and JGB Collateral, LLC, as collateral agent for the Purchasers (the "Agent"). Pursuant to the Purchase Agreement, the Company agreed to sell to the Purchasers (i) 10% Original Issue Discount Secured Convertible Debentures (the "Debentures") with an aggregate principal amount of $7,608 and (ii) warrants (the "Warrants") to purchase up to 1,000,000 shares of the Company's common stock, par value $0.01 per share (the "Common Stock"), for an exercise price of $2.31 per share, subject to adjustments as set forth in the Warrants, for a total purchase price of $7,000. Pursuant to ASC 825, *Fair Value Option*, the Company made an irrevocable election at the time of issuance to report the Debentures at fair value with changes in fair value recorded through the Company's consolidated statements of operations as other income (expense) in each reporting period. During the nine months ended April 30, 2024, the change in fair value expense recorded was $1,095.

 

*Debentures*

The Debentures bore interest at a rate of 10% per annum. The Debentures were convertible, at any time after their issuance date at the option of the Purchasers, into shares of Common Stock at a conversion price equal to $3.01 per share (the "Conversion Price"), subject to adjustment as set forth in the Debentures. Following the July 24, 2023 consummation of the Company's sale of certain assets and assignment of certain liabilities of Enzo Clinical Labs, Inc., to Labcorp pursuant to the Asset Purchase Agreement dated March 16, 2023, the Company prepaid $4,000 of the outstanding principal amount prior to July 31, 2023. In May 2024, the Company repaid in full the remaining principal balance of $3,609.

*Warrants*

The Warrants are exercisable for five years from May 19, 2023, at an exercise price of $2.31 per share, subject, with certain exceptions, to adjustments in the event of stock splits, subsequent dilutive offerings and certain fundamental transactions, as more fully described in the Warrant. The Warrants are eligible for any dividends paid on common stock. The warrant holders were paid $100 in dividends in December 2024.

*Registration Rights Agreement*

In connection with the Purchase Agreement, the Company was obligated to file a registration statement pursuant to which the Purchasers could sell the Common Stock issuable upon the conversion of the Debentures and the exercise of the warrants in a public offering. There is no right to a conversion of the Debentures into shares as the Debentures have been repaid in full.

**Note 8 – Long term debt**

In April 2020, the Company's subsidiary in Switzerland received a loan of CHF 400 (or $400, based on the foreign exchange rate as of July 31, 2020) from the Swiss government under the "Corona Krise" emergency loan program in response to the COVID-19 pandemic. This loan is uncollateralized and bears 0% interest. In January 2022, the bank agent of the Swiss government informed our subsidiary that the loan had to be fully amortized within a maximum of eight years and the first of semiannual amortization payments of CHF 33 began in March 2022. Based on this amortization schedule, the loan will be repaid by September 2027. The current portion of this loan is included in other current liabilities and the long term portion in long term debt – net as of April 30, 2025 and July 31, 2024.

Minimum future annual principal payments under this agreement as of April 30, 2025 are as follows:

---

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

| Total principal payments | 202 |
| Less: current portion, included in other current liabilities | (73) |
| Long term debt – net | $129 |

**Note 9 – Leases**

The Company determines if an arrangement is or contains a lease at contract inception. The Company leases buildings, office space, and equipment through operating 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. 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 (e.g., 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 3 years. Certain of the Company's leases have terms that include renewal options that are reasonably certain to be exercised. Certain of the Company's lease agreements include rental payments adjusted periodically for inflation which are included in the lease liabilities.

The following table summarizes the Company's right of use assets and associated liabilities of its continuing operations as of the dates indicated:

*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, 2025 and July 31, 2024, the Company had established reserves of $117 and $114, respectively, which are included in accrued liabilities for payroll, benefits and commissions, 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 11 – Stockholders' equity**

***Controlled Equity Offering***

In May 2023, the Company entered into a sales agreement (the "Sales Agreement") with B. Riley Securities, Inc. as sales agent ("Riley"). Under the Sales Agreement, the Company may offer and sell, from time to time, through Riley, shares of the Company's common stock, par value $0.01 per share ("Shares") having an aggregate offering price of up to $30 million. The Company pays Riley 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 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 Riley or the Company, as permitted therein. In May 2023, the Company filed with the SEC a "shelf" registration and sales agreement prospectus covering the Sales Agreement. A total of $150 million of securities, including those covered by the Sales Agreement, may be sold under the shelf registration which was declared effective in July 2023. There was no activity with respect to the controlled equity offering during the nine months ended April 30, 2025 or 2024.

 

*Incentive stock plans*

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. In January 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. At the fiscal 2020 annual stockholders' meeting 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 is equal to or greater than fair market value of the common stock on the date of grant. The Amended and Restated 2011 Plan 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 will remain in effect until they have been exercised or terminated, or have expired. As of April 30, 2025, there were approximately 4,798,000 shares of common stock available for grant under the Amended and Restated 2011 Plan.

The Company estimates the fair value of each stock option award on the measurement date using a Black-Scholes option pricing model or the fair value of our stock at the date of grant. The fair value of awards is amortized to expense on a straight-line basis over the requisite service period. The Company expenses restricted stock awards based on vesting requirements, primarily time elapsed.

Listed below are the assumptions used to determine the fair value of options granted during the periods indicated:

---

| | | |
|:---|:---|:---|
|  | **Nine Months Ended<br> April 30** | **Nine Months Ended<br> April 30** |
|  | **2025** | **2024** |
| Risk free interest rate % | 3.03% – 5.35 | 5.00% |
| Expected term of option | 3.5 years | 3.5 years |
| Expected stock price volatility | 70% | 70% |
| Expected dividend yield | 0% | 0% |

---

The risk-free interest rate is based on the yield of Daily U.S. Treasury Yield Curve Rates with terms equal to the expected term of the options as of the grant date. The expected term of options is determined using the simplified method, as provided in an SEC Staff Accounting Bulletin, and the expected stock price volatility is based on the Company's historical stock price volatility.

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

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **Three months ended<br> April 30,** | **Three months ended<br> April 30,** | **Nine months ended <br> April 30,** | **Nine months ended <br> April 30,** |
|  | **2025** | **2024** | **2025** | **2024** |
| Stock options | $82 | $90 | $288 | $833 |
| Restricted stock units | 92 | 117 | 235 | 710 |
|  | $174 | $207 | $523 | $1543 |

**Note 12 – Segment reporting**

The Company has one reportable segment, Products, which focuses on labeling and detection technologies from DNA to whole cell analysis, including a comprehensive portfolio of thousands of high-quality products, including antibodies, genomic probes, assays, biochemicals, and proteins. The Company's proprietary products and technologies play central roles in translational research and drug development areas, including cell biology, genomics, assays, immunohistochemistry, and small molecule chemistry. The Company evaluates segment performance based on segment income (loss) before taxes. Costs excluded from segment income (loss) before taxes and reported as "Corporate & Other" consist of corporate general and administrative costs, which are not allocable to the Products segment.

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 Corporate & Other segment. Legal and related expenses specific to the Products' segment's activities are allocated to that segment.

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

**Note 13 – Contingencies**

**<u>Settled or Inactive Legal Matters</u>**

***Ransomware Attack***

In April 2023, the Company experienced a ransomware attack (the "ransomware attack") that impacted certain critical information technology systems, principally of the discontinued operations. The Company later became aware that certain data, including names, test information, and Social Security numbers, was accessed, and in some instances, exfiltrated from the Company's information technology systems as part of this incident. The investigation identified unauthorized access to or acquisition of clinical test information of approximately 2,470,000 individuals. The Social Security numbers of approximately 600,000 of these individuals may also have been involved. Additionally, the Company determined that some employees' information may have been involved. The Company provided notice to the individuals whose information may have been involved, as well as to regulatory authorities, in accordance with applicable law.

As a result of the ransomware attack, Enzo was subject to regulatory inquiry from the New York Attorney General, a joint inquiry from the Connecticut and New Jersey Attorneys General and an inquiry from the Utah Attorney General. All inquiries asked questions about the ransomware attack, as well as the corrective actions taken in response. The Company responded to all such inquiries, and there have been no further inquiries from the Utah Attorney General. The matters with the New York, Connecticut and New Jersey Attorneys General are now closed, as they were resolved by agreements with each of the three states effective August 8, 2024. A provision was recorded in the consolidated financial statements as of July 31, 2024 based on the settlement terms of the agreements. In September 2024, the Company paid the full settlements totaling $4,500.

Enzo was also subject to regulatory inquiries from the U.S. Department of Health and Human Services Office for Civil Rights (the "Office for Civil Rights") regarding the ransomware attack. The Company has responded to all requests. It is not known at this time whether the Office for Civil Rights will seek a penalty against the Company. We are unable to evaluate the likelihood of an outcome, favorable or unfavorable, to the Company or to estimate the amount or range of any potential liability, if any, at this time.

***In re Enzo Biochem Data Breach Litigation*, No. 2:23-cv-04282 (EDNY)**

In the Eastern District of New York ("EDNY"), twenty putative class actions were consolidated alleging various harms stemming from the April 2023 data incident ("EDNY Federal Action"). Lead counsel was appointed and filed a Consolidated Amended Complaint on November 13, 2023. The complaint sought to certify a federal class as well as several state subclasses. The Consolidated Amended Complaint brings various statutory and common law claims, including negligence, negligence per se, breach of fiduciary duty, breach of implied contract, breach of the implied covenant of good faith and fair dealing, violation of the New York's General Business Law § 349, Invasion of Privacy, violations of the Connecticut Unfair Trade Practices Act, and violations of the New Jersey Consumer Fraud Act.

The parties reached a class-wide settlement agreement in the sum of $7,500 which the Court granted approval of at the final fairness hearing held on June 10, 2025. Approximately $800 of the $7,500 settlement was paid in March 2025 to cover class action notice costs. The remaining balance of approximately $6,700 must be remitted by July 10, 2025.

**<u>Other Settled or Inactive Matters</u>**

On February 25, 2022, Barry Weiner, the Company's co-founder and President, notified the Company that he was terminating his employment as President of the Company for "Good Reason," as defined in his employment agreement. The Company accepted Mr. Weiner's termination, effective April 19, 2022, but disagreed with Mr. Weiner's assertion regarding "Good Reason." On October 24, 2023, the Company and Mr. Weiner reached an agreement resolving the dispute, and a provision was made in the financial consolidated statements as of July 31, 2023 based on the settlement agreement. The Company paid Mr. Weiner $3,600, less applicable withholding taxes, related to the agreement in November 2023.

On or about March 2, 2023, a Verified Complaint was filed in the Supreme Court of the State of New York, New York County captioned Elazar Rabbani (as plaintiff) v. Mary Tagliaferri, et al. (as defendants), Index No. 651120/2023. The Verified Complaint purports to assert causes of action for breach of fiduciary duty and corporate waste under N.Y.B.C.L. § 720, and seeks an accounting and certain injunctive relief. On August 4, 2023, defendants moved to dismiss all the causes of action asserted in the Verified Complaint. Plaintiff filed an amended complaint on or about October 4, 2023, adding, among other things, an additional cause of action for violation of N.Y.B.C.L. § 626. On October 23, 2023, defendants filed a reply in further support of their motion to dismiss. On November 6, 2023, plaintiff filed an opposition to defendants' motion to dismiss. On November 17, 2023, defendants filed a reply brief in further support of their motion to dismiss the amended complaint. On or about July 17, 2024, the Court granted, in part, the defendants' motion to dismiss the amended complaint. On or about August 16, 2024, plaintiff noticed an appeal from the order granting that dismissal. On or about September 18, 2024, plaintiff filed a Verified Second Amended Complaint. On October 11, 2024, the defendants filed a joint stipulation and letter requesting the court to extend the deadline to respond to the Second Amended complaint from October 18, 2024 to November 18, 2024. On November 15, 2024, the plaintiff discontinued the derivative case and the related appeal (without prejudice).

In April 2024, the Company engaged in settlement negotiations with a government payer in our discontinued operations and reached a verbal settlement. The settlement was finalized in a formal written settlement agreement on August 14, 2024. The settlement resolved allegations that Enzo Clinical Labs, Inc. overbilled the Connecticut Medicaid program for testing services. The settlement was paid in August 2024 for $1,700 to resolve the State of Connecticut's allegations and $175 was paid to settle whistleblowers' legal fees.

**<u>Open and Active Legal Matters</u>**

***Pending Class Action Litigation***

***Maria Sgambati et al., v. Enzo Biochem, Inc., et al*., Index No. 619511/2023 (N.Y. Sup. Ct.)**

This is a putative class action pending in state court alleging various harms stemming from the April 2023 data incident. The complaint seeks to certify a class of New York residents. The complaint brings claims of negligence; negligence *per se*; breach of implied covenant and good faith and fair dealing; breach of duty; breach of implied contract; and violations of New York's Deceptive Acts and Practices § 349. The Company has filed a motion to stay this action pending the resolution of the EDNY Federal Action, and the motion was granted by the court. The Company intends to seek dismissal of this action once the settlement in the EDNY Federal Action receives final approval from the court, likely sometime in 2025.

***Louis v. Enzo Biochem, Inc. et al.*, Index No. 653281/2023 (N.Y. Sup. Ct.)**

This is a putative class action pending in state court alleging various harms stemming from the April 2023 data incident. The complaint seeks to certify a class of New York citizens. The complaint brings claims of negligence; negligence *per se*; breach of duty; breach of implied contract; breach of implied covenant of good faith and fair dealing; and violations of New York's Deceptive Acts and Practices § 349. The Company has filed a motion to stay this action pending the resolution of the EDNY Federal Action, and the motion remains pending. The Company intends to seek dismissal of this action once the settlement in the EDNY Federal Action receives final approval from the court, likely sometime in 2025.

**<u>Other Open and Active Legal Matters</u>**

On or about September 26, 2023, James G. Wolf, individually and as the trustee of the Wolf Family Charitable Foundation, Barbaranne R. Wolf, Stephen Paul Wolf, and Preston M. Wolf (collectively the "Petitioners") initiated an appraisal action against the Company in the New York Supreme Court for Suffolk County. Petitioners seek an appraisal of the value of their shares in the Company. On or about April 1, 2025, Petitioners filed a motion seeking to compel an "advance payment" of 80% of what they contend to be the fair value of their shares, plus prejudgment interest and attorneys' fees. In their papers, Petitioners announced their position, through an accompanying preliminary valuation report, that the alleged fair value of their shares as of the valuation date was "greater than $3.50 per share." The Company disputes this contention. Pursuant to a briefing schedule co-ordered by the Court, in early July 2025, the Company anticipates filing papers opposing Petitioners' motion, including the contention that they are entitled to any form or advance payment for their shares, and their position concerning the valuation of their shares.

On September 18, 2024, we received an unsealed complaint filed by whistleblowers in the Southern District of New York ("SDNY") alleging, among other things, that the Company falsely billed Medicaid and Medicare for COVID-19 tests by utilizing inappropriate diagnostic codes to trigger payments for such tests. The SDNY advised the court that the government was not intervening in the case; however, the private plaintiffs are still pursuing the case on the governments' behalf. The Court agreed to stay discovery in the case pending the submission and decision on the Company's anticipated motion to dismiss the complaint (the entire case). The Company's motion to dismiss is due on June 23, 2025. We believe there are meritorious defenses to the claims set forth in the complaint and the Company will vigorously defend itself. A probable settlement amount is not estimable at this time.

The Company terminated the employment of Elazar Rabbani, Ph.D., the Company's former Chief Executive Officer, effective April 21, 2022. Dr. Rabbani was a director of the Company until the Annual Meeting on April 30, 2024, when his term expired. Dr. Rabbani was a party to an employment agreement with the Company that entitled him to certain termination benefits, including severance pay, acceleration of vesting of share-based compensation, and continuation of benefits. Based on the terms of his employment agreement, the Company estimated and accrued a charge of $2,600 in fiscal year 2022. The charge was partially offset by the reversal of bonus accruals. In May 2022, the Company paid Dr. Rabbani $2,123 in severance (the payment constituted taxable income, but the Company did not withhold taxes from the payment). In July 2022, the Company paid Dr. Rabbani's income and other withholding taxes of $1,024 related to that payment on Dr. Rabbani's behalf. On July 8, 2022, the Company filed a demand for arbitration with the American Arbitration Association (the "AAA") seeking, among other things, a declaration that the Company had fully satisfied its contractual obligations to Dr. Rabbani and seeking the tax withholding reimbursement referenced above. On August 4, 2022, Dr. Rabbani filed counterclaims in the arbitration seeking, among other things, a bonus for fiscal year 2021 and additional severance that he asserted was owed to him. After a lengthy stay of the arbitration proceeding to allow for settlement negotiations, the parties have decided to move forward via the arbitration process. The arbitrator has set a schedule for the remainder of the arbitration up through the hearing on November 17-21, 2025. A provision was made in the consolidated financial statements as of July 31, 2023 and updated as applicable through the period ended April 30, 2025 based on a reasonable estimate of loss; however, the actual exposure may differ.

The Company (as plaintiff) has brought cases in the United States District Court for the District of Delaware ("the Court"), alleging patent infringement against various companies. At this time, all of such cases have been resolved, except for one. There is currently one case that was originally brought by the Company that is still pending in the Court. In that case, Enzo alleges patent infringement of the '197 patent against Becton Dickinson defendants. The claims in that case are stayed.

On September 2, 2021, the U.S. Patent and Trademark Office ("PTO") issued a non-final office action in an *ex parte* reexamination concerning the '197 Patent. In the office action, the PTO rejected certain claims of the '197 Patent for nonstatutory double-patenting. Enzo responded to the office action on January 3, 2022. Becton Dickinson requested another *ex parte* reexamination concerning the '197 patent on July 26, 2022. On September 16, 2022, the PTO ordered that *ex parte* reexamination as to certain claims of the '197 patent. Enzo filed a petition to terminate that second reexamination proceeding on November 16, 2022, which was denied on July 26, 2024. The PTO merged the *ex parte* reexamination proceedings as of August 2, 2024. On September 17, 2024, the PTO issued an office action, rejecting the claims subject to the merged reexamination proceedings. Enzo filed a response to that office action on December 17, 2024. On February 6, 2025, the PTO issued a final rejection of the claims (2, 5, 18, 20, and 228) in the *ex parte* reexamination proceedings. The Company is considering appeal options.

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.

**<u>Overview</u>**

The Company has operated as a life sciences company for over 45 years. The primary business of Enzo today is conducted through its Enzo Life Sciences division, which focuses on labeling and detection technologies from DNA to whole cell analysis, including a comprehensive portfolio of thousands of high-quality products, including antibodies, genomic probes, assays, biochemicals, and proteins. The Company's proprietary products and technologies play central roles in translational research and drug development areas, including cell biology, genomics, assays, immunohistochemistry, and small molecule chemistry. The Company monetizes its technology primarily via sales through our global distribution network and licensing. Enzo Life Sciences is operated through the Company's wholly-owned subsidiary Enzo Life Sciences, Inc. and its wholly-owned domestic and foreign subsidiaries. Costs excluded from Enzo Life Sciences financial results consist of corporate general and administrative costs and minimal therapeutic research and development expenses. These costs are reported within the consolidated financial statements as "Corporate and Other" (see Note 12 in the Notes to Consolidated Financial Statements for further segment information).

On April 22, 2025 the Company announced that its Board of Directors (the "Board") had commenced a review of strategic alternatives after receiving multiple inquiries regarding a potential transaction with the Company. In connection with this process, the Board has formed a special committee of independent directors (the "Strategic Committee") authorized to evaluate a broad range of opportunities to maximize value for shareholders, including a potential strategic transaction, business combination, full sale of the Company or return of excess capital to shareholders. The Strategic Committee has engaged BroadOak Capital Partners as financial advisor and to assist in evaluating any inbound expressions of interest and other potential transactions. There can be no assurance that the Company's strategic review process will result in any transaction or other strategic outcome. The Company does not intend to disclose further developments on this strategic review process unless and until a transaction is approved and entered into, or the process is discontinued.

*Discontinued operations – sale of Clinical Services business to Labcorp*

Prior to July 24, 2023, we operated a clinical laboratory, doing business as Enzo Clinical Labs, which provided reference, molecular and esoteric diagnostic medical testing services in the New York, New Jersey, and Connecticut medical communities. Effective July 24, 2023, we completed the sale of certain assets used in the operation of Enzo Clinical Labs and the assignment of certain clinical lab liabilities to Laboratory Corporation of America ("Labcorp") for an aggregate purchase price of $113.25 million in cash. In accordance with the sale, we ceased our clinical services operations. Excluded from the sale of the clinical services assets were its cash and accounts receivable. As a consequence of the sale, we have classified as discontinued operations all income and expenses attributable to the clinical services business for all periods presented.

 

*Ransomware attack*

In April 2023, the Company experienced a ransomware attack that impacted certain critical information technology systems, principally of the discontinued operation. In response, we promptly deployed containment measures, including disconnecting our systems from the internet, launching an investigation with assistance from third-party cybersecurity experts, and notifying law enforcement. We adhered to our disaster recovery plan, which enabled us to maintain operations throughout the incident response process. The Company's facilities remained open, and we continued to provide services to patients and partners. We later became aware that certain data, including names, test information, and Social Security numbers, was accessed, and in some instances, exfiltrated from the Company's information technology systems as part of this incident. The investigation identified unauthorized access to or acquisition of clinical test information of approximately 2.5 million individuals. The Social Security numbers of approximately 600,000 of these individuals may also have been involved. Additionally, the Company determined that some employees' information may have been involved. The Company provided notice to the individuals whose information may have been involved, as well as to regulatory authorities, in accordance with applicable law. The Company has incurred, and may continue to incur, related expenses. The Company's cybersecurity insurance carrier covered up to $3 million of the remediation costs related to the incident and paid service providers from the policy proceeds.

The Company remains subject to risks and uncertainties as a result of the incident, including as a result of the data that was accessed or exfiltrated from the Company's network as noted above. Additionally, security and privacy incidents have led to, and may continue to lead to, additional regulatory scrutiny and class action litigation exposure. See Note 13 of the consolidated financial statements for discussion of litigation in connection with this incident.

*NYSE Listing Notice and Transfer of Listing*

On January 8, 2025, the Company received a letter from the New York Stock Exchange (the "NYSE") notifying the Company that it was not in compliance with (i) Section 802.01B of the NYSE Listed Company Manual because, as of January 7, 2025, the Company's 30 trading-day average market capitalization was less than $50 million and its last reported stockholder's equity as of October 31, 2024 was less than $50 million and (ii) Section 802.01C of the NYSE Listed Company Manual because the average closing price of the Company's Common Stock (the "Common Stock") was less than $1.00 over a consecutive 30 trading-day period. The notice did not result in the immediate delisting of the Common Stock from the NYSE, but the Company could have been delisted from the NYSE if it did not regain compliance with the foregoing continued listing standards in accordance with NYSE requirements.

On March 28, 2025, we notified the NYSE of our decision to voluntarily delist our common stock from NYSE. In connection with the delisting, the last day of trading of the Company's common stock on NYSE was April 17, 2025. The Company's common stock began trading on OTCQX on April 21, 2025 under the symbol "ENZB."

**Consolidated Results:**

The "2025 period" and the "2024 period" refer to the three months ended April 30, 2025 and 2024, respectively.

Revenues were $6.4 million in the 2025 period and $8.0 million in the 2024 period, a decrease of approximately $1.6 million or 20% due to a decline in all geographic areas of our customer base related to general continued headwinds in the life sciences tools space, including decreases in government grants, reduced R&D budgets, tariffs uncertainty and the timing of large orders fulfillment.

The cost of revenues was $3.8 million in the 2025 period and $4.3 million in the 2024 period, a decrease of $0.5 million or 12% due to lower revenues and the impact of cost containment initiatives. The gross profit margin was approximately 39% (41% excluding the inventory provision of $163) and 47% in the 2025 and 2024 periods, respectively. The decline in the 2025 period gross profit was driven by the reduction in revenues, which did not fully cover overhead burden and other fixed manufacturing costs.

The cost of revenues – inventory provision was approximately $0.2 million for inventory we intended to use in manufacturing and sell to laboratory customers which we fully reserved in the 2025 period. This provision represents approximately 2.5% of the 2025 period's revenues.

Research and development expenses were $0.5 million in the 2025 period and $0.6 million in the 2024 period, a decrease of $0.1 million or 17% due to cost containment measures and lower patent expense.

Selling, general and administrative expenses were $4.9 million during the 2025 period versus $4.5 million during the 2024 period, an increase of $0.4 million or 10%. For the Products segment there was an increase in administrative and information technology costs. For the Other segment, there were higher strategic consulting costs, health and life insurance, and bonus accruals, as the 2024 period had bonus reversals.

Legal and related expenses were $0.5 million during the 2025 period and $0.7 million in the 2024 period, a decrease of $0.2 million or 33%. During the 2024 period, we required more legal expertise and assistance associated with corporate matters.

Interest income, net was $0.4 million in the 2025 period compared to $0.7 million in the 2024 period, a decrease of $0.3 million or 47% due to the decrease in the balance of cash held in a money market account and a decline in the interest rate earned due to Federal Reserve actions to lower discount rates.

In the 2024 period we recorded a fair value adjustment charge of approximately $0.4 million for the convertible debentures based on their fair value as of April 30, 2024, and which were due and fully repaid in May 2024.

Other income in both periods is primarily from the subletting of a portion of our office space in New York, NY.

The foreign exchange gain recognized by the Products segment during the 2025 period was $0.5 million compared to a loss of $0.5 million in the 2024 period, a favorable variance of $1.0 million. At the end of the 2025 period as compared to its start, the British pound and Swiss franc greatly appreciated compared to the U.S. dollar as a result of U.S. economic policies, which resulted in revaluation gains on certain assets and liabilities carried in those foreign currencies. At the end of the 2024 period as compared to its start, those foreign currencies depreciated in value compared to the U.S. dollar, resulting in revaluation losses on those certain assets and liabilities.

**\*\*** **not meaningful**

**Consolidated Results:**

The "2025 period" and the "2024 period" refer to the nine months ended April 30, 2025 and 2024, respectively.

Revenues were $19.9 million in the 2025 period and $24.4 million in the 2024 period, a decrease of approximately $4.4 million or 18% due to a decline in all geographic areas of our customer base related to general continued headwinds in the life sciences tools space, including decreases in government grants, reduced R&D budgets, tariffs uncertainty and the timing of large orders fulfillment.

The cost of revenues was $11.0 million in the 2025 period and $13.0 million in the 2024 period, a decrease of $2.0 million or 15% due to lower revenues and the impact of cost containment initiatives. The gross profit margin was approximately 43% (45% excluding the inventory provision) in the 2025 period and 47% 2024 period and was driven by the reduction in revenues, which did not fully cover overhead burden and other fixed manufacturing costs.

The cost of revenues – inventory provision was approximately $0.4 million for inventory we intended to use in manufacturing and sell to laboratory customers which we fully reserved in the 2025 period. This provision represents approximately 2% of the 2025 period's revenues.

Research and development expenses were $1.5 million in the 2025 period and $2.0 million in the 2024 period, a decrease of $0.5 million or 24%. There was an emphasis on manufacturing effort in the 2025 period and cost containment measures, including reduction in patent expense.

Selling, general and administrative expenses were $14.3 million during the 2025 period versus $16.6 million during the 2024 period, a decrease of $2.2 million or 13%. The Other segment expense declined $2.0 million primarily due to severance provisions and accelerated recognition of share based compensation in the 2024 period related to a former senior officer. The Products segment expense decreased $0.2 million as compared to 2024 period due to lower headcount, sales commissions, travel expenses, and bonus accruals.

Legal and related expenses were $1.3 million during the 2025 period and $2.5 million in the 2024 period, a decrease of $1.3 million or 50%. During the 2024 period, we required significantly more legal expertise and assistance associated with corporate matters as discussed in Note 13 Contingencies.

Interest income, net was $1.5 million in the 2025 period compared to $2.6 million in the 2024 period, a decrease of $1.1 million or 44% due to a decrease in the balance of cash held in a money market account and a decline in the interest rate earned due to Federal Reserve actions to lower discount rates.

In the 2024 period we recorded a fair value adjustment charge of approximately $1.1 million for the convertible debentures based on their fair value as of April 30, 2024, which were due and fully repaid in May 2024.

Other income in both periods is primarily from the subletting of a portion of our office space in New York, NY.

The foreign exchange gain recognized by the Products segment during the 2025 period was $0.1 million compared to a loss of $0.8 million in the 2024 period, a favorable variance of $0.9 million. At the end of the 2025 period as compared to its start, the British pound and Swiss franc slightly appreciated compared to the U.S. dollar, which resulted in small revaluation gains on certain assets and liabilities carried in those foreign currencies. At the end of the 2024 period as compared to its start, those foreign currencies has significantly depreciated in value compared to the U.S. dollar, resulting in larger revaluation losses on those certain assets and liabilities.

**Liquidity and Capital Resources**

Our aggregate cash and cash equivalents as of April 30, 2025 was $36.7 million and $52.4 million as of July 31, 2024. The decrease of $15.7 million in our cash and cash equivalents balance as of April 30, 2025 was primarily due to the period net loss, cash used to pay down accrued liabilities, particularly those of the discontinued operations, and the payment of a dividend of $5.3 million, partially offset by the release from escrow of $5.0 million, as discussed below. Based on the current available working capital, management believes the Company has sufficient funds to meet its operating requirements for at least the next twelve months from the date of the filing of this report. Our working capital was $31.3 million and $45.2 million as of April 30, 2025 and July 31, 2024, respectively.

Net cash used in operating activities during the 2025 period was $14.2 million, compared to $25.2 million during the 2024 period, a favorable variance of $11.0 million, primarily due to the smaller net loss from continuing operations in the 2025 period and the larger paydowns of accounts payable – trade and accrued liabilities in the 2024 period.

Net cash provided by investing activities during the 2025 period was approximately $4.1 million and represents the release of cash held in escrow from the Labcorp Asset Purchase Agreement which closed in July 2023, partially offset by capital expenditures of $0.9 million. Net cash used in investing activities during the 2024 period was approximately $0.4 million for capital expenditures.

Net cash used in financing activities in the 2025 period was $5.6 million and primarily represents the payment of a $5.3 million dividend in December 2024. Cash used in the 2024 period amounted to $0.6 million primarily for taxes paid on bonuses paid in stock.

**Labcorp Asset Purchase Agreement and release of Cash in Escrow**

 ****

We had indemnification obligations to Labcorp under the Asset Purchase Agreement that could have required us to make payments to Labcorp and other related persons for any damages incurred by Labcorp or such related persons as a result of any breaches of our representations, warranties, covenants or agreements contained in the Asset Purchase Agreement, or arising from retained liabilities or certain third-party claims specified in the Asset Purchase Agreement. Generally, our representations and warranties survived for a period of 15 months from the closing date, which was July 24, 2023, other than certain fundamental representations, which survive until the expiration of the applicable statute of limitations. There is an indemnification cap with respect to a majority of the Company's indemnification obligations under the Asset Purchase Agreement with the exception of claims for actual fraud, the breach of any fundamental representations and certain other items, which are subject to a higher indemnification cap (up to the purchase price).

Pursuant to the terms of the Asset Purchase Agreement, we, Labcorp, and an escrow agent entered into an Escrow Agreement at closing, pursuant to which Labcorp deposited $5 million of the aggregate purchase price of the clinical service business into an escrow account in order to satisfy, in whole or in part, certain of our indemnity obligations, if any, that arose under the Asset Purchase Agreement. Labcorp made no claims and required only a reimbursement of certain legal fees it had incurred, which were immaterial. On October 30, 2024, the escrowed funds of $5.0 million were released to the Company.

**Off Balance Sheet Arrangements**

The Company does not have any "off-balance sheet arrangements" as such term is described in Item 303 of Regulation S-K.

**Critical Accounting Policies and Estimates**

*<u>General and estimates</u>*

The Company's discussion and analysis of its financial condition and results of operations are based upon Enzo Biochem, Inc.'s consolidated financial statements, which have been prepared in accordance with U.S. GAAP. 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.

On an on-going basis, we evaluate our estimates, including those related to contractual expense, allowance for expected credit losses, inventory, 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.

 

*<u>Contingencies</u>*

Contingencies are evaluated and a liability is recorded when the matter is both probable and reasonably estimable. Gain contingencies are evaluated and not recognized until the gain is realizable or realized.

 

*<u>Product revenues</u>*

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.

*<u>Accounts Receivable</u>*

 

Accounts receivable are reported at realizable value, net of expected credit losses, which is estimated and recorded in the period of the related revenue.

As of April 30, 2025 and July 31, 2024, Products accounts receivable, net were $4,309 and $3,988, respectively. As of April 30, 2025 and July 31, 2024, these totals include foreign receivables, net, of $782 and $1,185, respectively.

*<u>Inventory</u>*

The Company values inventory at the lower of cost (first-in, first-out) or net realizable value. 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.

*<u>Long-Lived Assets</u>*

The Company reviews the recoverability of the carrying value of long-lived depreciable assets of an asset or asset group for impairment if indicators of potential impairment exist. Should indicators of impairment exist, the carrying values of the depreciable assets are evaluated in relation to the operating performance and future undiscounted cash flows of an asset or asset group. The net book value of the depreciable long lived asset is adjusted to fair value if its expected future undiscounted cash flow is less than its book value.

During the nine months ended April 30, 2025 and 2024 there was no impairment of depreciable long-lived assets used in continuing operations.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk**

As a smaller reporting company, we are not required to provide the information required by this Item.

**Item 4. Controls and Procedures**

*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 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 each of our principal executive officer and principal financial officer. Based on the evaluation of our Disclosure Controls, our principal executive officer and principal financial officer have concluded that, as of April 30, 2025, our Disclosure Controls were effective to ensure that information required to be disclosed by us in the reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms and is accumulated and communicated to our management, including our principal executive officer and principal financial officer, as appropriate to allow timely decisions regarding required disclosure.

*Changes in Internal Control Over Financial Reporting*

There were no changes in our internal control over financial reporting that occurred during the period ended April 30, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

**PART II - OTHER INFORMATION**
