Sentiment and the balance of points

Rhea-AI Sentiment reads the wording of the document, how positive or negative its language is on a 1 to 5 scale. The balance of points shown with the takes weighs what the document actually discloses, so the two can disagree, for example when a trial that missed its main goal is described in upbeat language.

How this balance works

Rhea-AI gives every point it takes from this document a weight. Minor counts 1, Moderate 3 and Major 9, so one Major point outweighs several Minor ones. The bar adds up the weights on each side, and when neither side holds more than 65% of the total the balance reads Mixed.

It reads the document as published, with the same rules for every company, and it does not look at what the market expected or at how the stock traded, so a point can be objectively good on a day the stock falls.

Rhea-AI Sentiment measures something else, the tone of the wording.

Filing Explained

Two warrants permit purchases of up to 2,653,308 and 105,911 shares; issuance of those shares depends on exercise.

As of September 30, 2026, Quantum had $245.9 million in non-cancelable commitments to purchase inventory. The commitment amount exceeds the $67,416 thousand in cash and equivalents reported at the same date. These are commitments to buy inventory, not a statement that the amount had already been paid.

The filing also reports a Forbearance Warrant for up to 2,653,308 shares at $8.81 and a Conversion Warrant for up to 105,911 shares at $5.1940. The warrants permit purchases, rather than report issuance, of those shares; if shares are issued upon exercise, that would increase the share count and reduce existing holders’ percentage ownership, absent offsetting changes.

Remaining performance obligations financial
"Remaining performance obligations (“RPO”) refers to goods and services"
Remaining performance obligations are the work a company still needs to complete for its customers, like finishing a service or delivering a product. It’s important because it shows how much future income the company has coming in from current agreements, giving a clearer picture of its ongoing business.
full valuation allowance financial
"established a full valuation allowance against our U.S. and certain foreign net deferred tax assets"
liability-classified warrants financial
"related to its liability-classified warrants"
Liability-classified warrants are financial instruments that give the holder the right to buy a company’s stock but are treated on the balance sheet as a debt-like obligation rather than as equity. For investors this matters because the company must record them at fair value and remeasure them each reporting period, which can create swings in reported profits and liabilities and affect perceived financial stability—similar to how a store must regularly update the value of a loan it owes instead of listing it as ownership.
Rule 10b5-1(c) regulatory
"trading plan intended to satisfy Rule 10b5-1(c)"
Rule 10b5-1(c) is an SEC guideline that lets company insiders set up a written, pre-planned schedule to buy or sell their company stock when they are not in possession of material, nonpublic information. For investors, it matters because such plans can reduce the appearance of insider trading by separating decisions from inside knowledge—like putting your trades on autopilot—while also requiring scrutiny since pre-planned trades can still affect market confidence and share value.

Note Regarding Forward-Looking Statements
As used in this Quarterly Report on Form 10-Q (this "Quarterly Report"), the terms the "Company," "Quantum," "we," "us," and "our" refer to Quantum Corporation and its subsidiaries taken as a whole, unless otherwise noted or unless the context indicates otherwise.
This report contains forward-looking statements. All statements contained in this report other than statements of historical fact, including, but not limited to, statements regarding our future operating results, financial position and liquidity, including the sufficiency of our capital resources; our business strategy, focus and plans; our market growth and trends; our products, services and expected benefits thereof; and our objectives for future operations, are forward-looking statements. The words “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “could,” “would,” “project,” “plan,” “potentially,” “preliminary,” “likely,” and similar expressions are intended to identify forward-looking statements. We have based these forward-looking statements largely on our current expectations and projections about future events and trends that we believe may affect our financial condition, results of operations, business strategy, short-term and long-term business operations and objectives, and financial needs. These forward-looking statements are subject to a number of risks, uncertainties, and assumptions, including the competitive pressures that we face; risks associated with executing our strategy; the impact of macroeconomic and geopolitical trends and events; the need to manage third-party suppliers and the distribution of our products and the delivery of our services effectively; the protection of our intellectual property assets, including intellectual property licensed from third parties; risks associated with our international operations; the development and transition of new products and services and the enhancement of existing products and services to meet customer needs; our response to emerging technological trends; the execution and performance of contracts by us and our suppliers, customers, clients and partners; the hiring and retention of key employees; risks associated with business combination and investment transactions; the outcome of any claims and disputes; our ability to generate sufficient cash flows and to obtain additional financing on acceptable terms, if at all; our ability to remediate the material weaknesses in our internal control over financial reporting and to maintain effective internal control over financial reporting following remediation; risks related to changes in our management; and those risks described under Part I, Item 1A, “Risk Factors” in our Annual Report on Form 10-K for the fiscal year ended March 31, 2026 and in our subsequent filings with the SEC. Moreover, we operate in a competitive and changing environment. New risks emerge from time to time. It is not possible for our management to predict all risks, nor can we assess the effect of all factors on our business or the extent to which any factor, or combination of factors, may cause actual results to differ materially from those contained in any forward-looking statements we may make. In light of these risks, uncertainties, and assumptions, the future events and trends discussed in this report may not occur and actual results could differ materially and adversely from those anticipated or implied in the forward-looking statements. Accordingly, you should not rely on forward-looking statements as predictions of future events. Although we believe that the expectations reflected in the forward-looking statements are reasonable, we cannot guarantee that the future results, performance, or events and circumstances reflected in the forward-looking statements will be achieved or occur. We undertake no obligation to update any of these forward-looking statements for any reason after the date of this report or to conform these statements to actual results or revised expectations.

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (unaudited)

NOTE 1: DESCRIPTION OF BUSINESS AND SIGNIFICANT ACCOUNTING POLICIES
Description of Business
Quantum Corporation, together with its consolidated subsidiaries (“Quantum”, the “Company”, "our" or "we"), stores and manages digital video and other forms of unstructured data, providing streaming performance for video and rich media applications, along with low-cost, long-term storage systems for data protection and archiving. The Company helps customers around the world capture, create and share digital data and preserve and protect it for decades. The Company’s software-defined, hyperconverged storage solutions span from non-volatile memory express (“NVMe”), to solid state drives (“SSD”), hard disk drives (“HDD”), tape and the cloud and are tied together leveraging a single namespace view of the entire data environment. The Company works closely with a broad network of distributors, value-added resellers (“VARs”), direct marketing resellers (“DMRs”), original equipment manufacturers (“OEMs”) and other suppliers to meet customers’ evolving needs.
Basis of Presentation
The accompanying unaudited condensed consolidated financial statements of the Company have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information. All intercompany balances and transactions have been eliminated. Certain information and footnote disclosures normally included in annual financial statements have been condensed or omitted. The Company believes the disclosures made are adequate to prevent the information presented from being misleading. However, the accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited consolidated financial statements and notes thereto included within the Company’s Annual Report
on Form 10-K for the fiscal year ended March 31, 2026 (the “Annual Report”).

The unaudited condensed consolidated interim financial statements reflect all adjustments, consisting only of normal and recurring items, necessary to present fairly our financial position as of September 30, 2026, the results of operations and comprehensive loss, our cash flows, and changes in stockholders’ deficit, as of and for three and six months ended September 30, 2026 and 2025. Interim results are not necessarily indicative of full year performance because of short-term variations.

The condensed consolidated balance sheet at March 31, 2026 was derived from audited financial statements for the year ended March 31, 2026 included in the Annual Report but does not contain all of the footnote disclosures from the annual financial statements.
Reclassifications
Certain prior-period amounts in the condensed consolidated statements of cash flows have been reclassified to conform to the current period presentation. These reclassifications had no effect on total cash flows.

We have aggregated Manufacturing and Service Inventory into a single line called Inventories on the Condensed Consolidated Balance Sheets and we have aggregated Accrued Restructuring into Accrued Compensation. Details of the balances in the Inventories line item have been included in Note 3 : Balance Sheet Information and Accrued Restructuring has been included in Note 6 : Restructuring Charges.
Liquidity
These condensed consolidated financial statements have been prepared in accordance with GAAP assuming the Company will continue as a going concern. The going concern assumption contemplates the realization of assets and satisfaction of liabilities in the normal course of business.

The Company generated cash flows from operations of approximately $14.3 million for the six months ended September 30, 2026. The Company has historically funded operations through the sale of common stock and term debt borrowings in Note 4: Debt and Note 7: Common Stock. Management believes that it has the ability to obtain additional debt or equity financing, if required, and has historically been able to do so. In the first half of fiscal year 2027, the Company has generated positive operating cash flows and management believes that expected operating cash flows will be sufficient to fund operations for at least one year from the condensed consolidated financial statements issuance date.

Table of Contents

Use of Estimates
The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the amounts reported and disclosed in the condensed consolidated financial statements and accompanying notes. Actual results could differ from these estimates and assumptions due to risks and uncertainties. Such estimates include, but are not limited to, the determination of standalone selling price for revenue arrangements with multiple performance obligations, inventory adjustments, useful lives of intangible assets and property and equipment, stock-based compensation, fair value of warrants, fair value of the Convertible Note and provision for income taxes including related reserves. Management bases its estimates on historical experience and on various other assumptions which management believes to be reasonable, the results of which form the basis for making judgments about the carrying values of assets and liabilities.
Restricted Cash
Restricted cash is comprised of bank guarantees and similar required minimum balances that serve as cash collateral in connection with various items including value added taxes, ongoing tax audits and leases in certain countries.
Accounts Receivable and Allowance for Credit Losses
Accounts receivable are recorded at the invoiced amount, and stated at realizable value, net of an allowance for credit losses. The Company maintains an allowance for credit losses for estimated losses based on historical experience and expected collectability of outstanding accounts receivable. The Company performs ongoing credit evaluations of its customers’ financial condition, and for the majority of its customers require no collateral. For customers that do not meet the Company’s credit standards, the Company may require a form of collateral, such as cash deposits or letters of credit, prior to the completion of a transaction. These credit evaluations require significant judgment and are based on multiple sources of information. The Company analyzes such factors as its historical bad debt experience, industry and geographic concentrations of credit risk, current economic trends and changes in customer payment terms. The Company will write-off customer balances in full to the reserve when it has determined that the balance is not recoverable. Changes in the allowance for credit losses are recorded in general and administrative expenses.

The Company has applied the practical expedient, where current conditions that do not affect the historical loss information are taken into account when determining the expected credit loss.
Warrant Accounting
The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance Accounting Standards Codification ("ASC") Topic 480, Distinguishing Liabilities from Equity (“Topic 480”) and ASC Topic 815, Derivatives and Hedging (“Topic 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to Topic 480, meet the definition of a liability pursuant to Topic 480, and whether the warrants meet all of the requirements for equity classification under Topic 815, including whether the warrants are indexed to the Company’s own common shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.
For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance or modification. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. This liability is subject to re-measurement at each balance sheet date until exercised, and any change in fair value is recognized in the Company’s condensed consolidated statements of operations and comprehensive loss. Quantum issued a Conversion Warrant in June 2026 and Forbearance Warrant in September 2025. See Note 4: Debt and Note 11: Fair Value of Financial Instruments, for further details.
Accounting Pronouncements Recently Adopted
In July 2025, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update ("ASU") 2025-05, Financial Instruments—Credit Losses (Topic 326): Measurements of Credit Losses for Accounts

Table of Contents

Receivable and Contract Assets. ASU 2025-05 was effective for the Company beginning on April 1, 2026, and did not have a material impact on our financial statement disclosures.
Recent Accounting Pronouncements Not Yet Adopted
In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income -Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses, which requires additional disclosures of specific expense categories included within each expense caption presented on the Statements of Operations. The new standard can be applied on either a fully retrospective or prospective basis. ASU 2024-03 will be effective for our fiscal year beginning April 1, 2027, and interim periods within our fiscal year beginning April 1, 2028, with early adoption permitted. The Company is currently evaluating the impact of this new standard on its financial statement disclosure.

In September 2025, the FASB issued ASU 2025-06, Targeted Improvements to the Accounting for Internal-Use Software” (Topic 350). The updates eliminate references to software development project stages and revises the criteria that must be met to begin capitalizing internal-use software costs. The standard permits entities to adopt the guidance using a prospective, retrospective, or modified transition approach and becomes effective for the Company beginning April 1, 2028, with early adoption permitted. The Company is currently assessing the potential impact that ASU 2025-06 will have on its financial statement disclosures.

In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which clarifies certain aspects of interim reporting guidance. The standard is effective for interim periods within fiscal years beginning after December 15, 2027, which will be the Company’s fiscal year beginning April 1, 2028, with early adoption permitted. The Company is currently evaluating the impact of this guidance on its interim financial statement disclosures.

In December 2025, the FASB issued ASU 2025-12, Codification Improvements, which amends a broad range of Topics to clarify guidance, correct errors, and make other improvements. The update clarifies that, when an entity reports a loss from continuing operations, it must consider whether instruments that may be settled in cash or shares and are classified as assets or liabilities are dilutive, including the related adjustments to the diluted net loss per share calculation, rather than presuming them to be antidilutive. The amendments to ASC 260 must be applied retrospectively to all periods presented. ASU 2025-12 will be effective for our fiscal year beginning April 1, 2027, including interim periods within that fiscal year, with early adoption permitted. The Company is currently evaluating the impact of this new standard, including the effect on diluted net loss per share related to its liability-classified warrants.

(1) The unamortized debt issuance costs related to the Term Loan are presented as a reduction of the carrying amount of the corresponding debt balance on the accompanying condensed consolidated balance sheet as of March 31, 2026.
Prior to June 2026, the Company’s debt consisted of (i) senior secured term loans (the “Term Loan”) under its Term Loan Credit and Security Agreement, dated August 5, 2021, as amended (the “Term Loan Credit Agreement”), and (ii) a 10.00% PIK Senior Secured Convertible Note due 2028 (the “Convertible Note”) issued on December 18, 2025 to Dialectic Technology SPV, LLC (“Dialectic”) in exchange for the Term Loans held by Dialectic. The Company elected the fair value option under ASC 825 for the Convertible Note. In connection with the Fifteenth Amendment to the Term Loan Credit Agreement, entered into on September 23, 2025 (the “Fifteenth Amendment”), the Company issued Dialectic a warrant to purchase up to 2,653,308 shares of its common stock (the “Forbearance Warrant”). For a description of the terms of, and amendments to, these instruments, see the notes to the audited consolidated financial statements included in the Annual Report.

On June 1, 2026, the Company entered into a Sixteenth Amendment to the Term Loan Credit Agreement to facilitate the Private Placement (as defined in Note 7 : Common Stock) and the Conversion (as defined below).

Pursuant to a Conversion Agreement dated June 1, 2026 (the “Conversion Agreement”), on June 4, 2026, Dialectic, as the sole beneficial owner of the Convertible Note, voluntarily converted the entire principal amount of the
15

Table of Contents

Convertible Note, together with all accrued and unpaid interest thereon, which was approximately $57.2 million, into shares of the Company’s common stock (the “Conversion”), and the Convertible Note was canceled.

As consideration for the Conversion, the Company (i) amended the Convertible Note to waive certain notice and settlement requirements otherwise applicable to a voluntary exchange; (ii) issued to Dialectic 3.1 million additional shares of the Company’s common stock, representing the present value of PIK interest that would have accrued on the Convertible Note through its stated maturity plus the Term Loan deferred cash interest owed to Dialectic, divided by the $5.1940 conversion price; and (iii) issued to Dialectic the Conversion Warrant (as defined in Note 7 : Common Stock). See Note 7 : Common Stock for additional information.

On June 4, 2026, the Company paid an aggregate of $57.8 million in connection with the termination of the Term Loan Credit Agreement, consisting of the entire outstanding principal amount, accrued interest, and fees and expenses incurred in connection with the termination. The Company recorded a loss on debt extinguishment of $11.7 million associated with this transaction.

On June 4, 2026 and pursuant to the terms of the Conversion Agreement, the Convertible Note was canceled, and the Indenture was satisfied and discharged in full. See Note 11: Fair Value of Financial Instruments for full details of the transaction.
Related Party Transactions
The Forbearance Warrant, Conversion Warrant and Convertible Note issued to Dialectic constitute related party transactions, as John Fichthorn, a member of the Company's board of directors, is also Managing Partner of Dialectic Capital Management, the investment adviser to Dialectic. The fair values of the Forbearance Warrant and Conversion Warrant as of September 30, 2026 are included in Note 11: Fair Value of Financial Instruments. The Convertible Note was canceled on June 4, 2026 when the indenture governing the Convertible Note was satisfied and discharged in full.

NOTE 8: NET LOSS PER SHARE
Equity Instruments Outstanding

Table of Contents

The Company has stock options, warrants, performance share units and restricted stock units granted under various stock incentive plans that, upon exercise and vesting, would increase shares outstanding.

The dilutive impact related to shares of common stock from incentive plans and outstanding warrants is determined by applying the treasury stock method to the assumed vesting of outstanding performance share units and restricted stock units and the exercise of outstanding options and warrants. The dilutive impact related to shares of common stock from contingently issuable performance share units is determined by applying a two-step approach using both the contingently issuable share guidance and the treasury stock method.

The following weighted-average outstanding shares of common stock equivalents were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been anti-dilutive (in thousands):

As of September 30, 2026, there were 13,909 shares of common stock equivalents related to performance-based stock options that vest only upon the achievement of specified performance conditions and the completion of a time-based service period. These contingently issuable options were excluded from the computation of diluted net loss per share for the three and six months ended September 30, 2026, and from the table above, as the specified performance conditions were not met as of September 30, 2026.

The Company had outstanding performance share units subject to market or performance conditions as of September 30, 2026 and 2025 that were eligible to vest into shares of common stock subject to the achievement of certain stock price or financial targets in addition to a time-based vesting period. These contingently issuable shares are excluded from the computation of diluted net loss per share if, based on current period results, the shares would not be issuable if the end of the reporting period were the end of the contingency period. There were 2,956 and 34,201 shares of contingently issuable performance share units subject to market or performance conditions that were excluded from the table above as the conditions were not satisfied as of September 30, 2026 and 2025, respectively.

NOTE 9: INCOME TAXES
The effective tax rate for the three and six months ended September 30, 2026 was (0.3)% and (0.4)%, respectively, as compared to (0.4)% and (0.6)% for the three and six months ended September 30, 2025, respectively. The effective tax rates differed from the federal statutory tax rate of 21% during each of these periods due primarily to unbenefited losses experienced in jurisdictions with valuation allowances on deferred tax assets as well as the forecasted mix of earnings in domestic and international jurisdictions.
As of September 30, 2026, including interest and penalties, the Company had $78.7 million of unrecognized tax benefits, $69.5 million of which, if recognized, would favorably affect the effective tax rate without consideration of the valuation allowance. As of September 30, 2026, the Company had accrued interest and penalties related to these unrecognized tax benefits of $1.3 million. The Company recognizes interest and penalties related to income tax matters in the income tax provision in the condensed consolidated statements of operations and comprehensive loss. As of September 30, 2026, $71.6 million of unrecognized tax benefits were recorded as a contra deferred tax asset in other long-term assets in the condensed consolidated balance sheets and $7.1 million (including interest and penalties) was recorded in other long-term liabilities in the condensed consolidated balance sheets. During the next 12 months, it is reasonably possible that approximately $1.8 million of tax benefits, inclusive of interest and penalties, that are currently unrecognized could be recognized as a result of the expiration of applicable statutes of limitations. Upon recognition of the tax benefit related to the expiring statutes of limitations, $0.8 million will be offset by the establishment of a related valuation allowance. The net tax benefit recognized in the condensed consolidated statements of operations and comprehensive loss is estimated to be $1.0 million.
NOTE 10: COMMITMENTS AND CONTINGENCIES

Table of Contents

Commitments to Purchase Inventory
The Company uses contract manufacturers for its manufacturing operations. Under these arrangements, the contract manufacturer procures inventory to manufacture products based upon its forecast of customer demand. The Company has similar arrangements with certain other suppliers. The Company is responsible for the financial impact on the supplier or contract manufacturer of any reduction or product mix shift in the forecast relative to materials that the third party had already purchased under a prior forecast. Such a variance in forecasted demand could require a cash payment for inventory in excess of current customer demand or for costs of excess or obsolete inventory. As of September 30, 2026, the Company had issued non-cancelable commitments for $245.9 million to purchase inventory from its contract manufacturers and suppliers.
Legal Proceedings
From time to time, we are a party to various legal proceedings and claims arising from the normal course of business activities. Based on current available information, we do not expect that the ultimate outcome of any additional currently pending unresolved matters, individually or in the aggregate, will have a material adverse effect on our results of operations, cash flows or financial position.
Litigation
Shareholder Litigation
On September 4, 2025, a shareholder class action complaint was filed in the United States District Court for the District of Colorado. The complaint identifies Seung Lee as the plaintiff and names Quantum Corporation and James J. Lerner, Kenneth P. Gianella, and Laura Nash as defendants. It alleges certain violations of Sections 10(b) and 20(a) of the Securities Exchange Act of 1934 and SEC Rule 10b-5 related to certain disclosures made in the Company’s quarterly and annual reports regarding its financial reporting for the third quarter of the Company’s fiscal year 2025 and its restatement of that financial reporting. The complaint sought to designate the plaintiff as the lead plaintiff for the class and define a class period of November 15, 2024 through August 18, 2025. On January 27, 2026, a revised final complaint named Hunsu Son as the lead plaintiff and reiterated the violations alleged in the original complaint. The revised complaint seeks an award of unspecified damages, costs, and expenses. The Company has filed a motion to dismiss the litigation, which has not yet been heard. The litigation is currently in its early stages and no discovery has taken place. As a result, the case has not progressed enough to support an opinion on potential outcomes or the possibility that damages could be awarded. Consequently, at this time, Quantum is not able to determine whether this lawsuit would have any material adverse effect on our business, operating results, or financial condition.
Derivative Litigation
On October 28, 2025, a shareholder derivative complaint was filed in the United States District Court for the District of Colorado. The complaint was filed by Brent Cullison derivatively on behalf of Quantum Corporation against James J. Lerner, Kenneth P. Gianella, Laura Nash, Don Jaworski, John Fichthorn, Hugues Meyrath, John R. Tracy, Emily White, James C. Clancy, and Tony J. Blevins. The complaint substantially repeats the allegations of the shareholder litigation described above and alleges related breaches of fiduciary duties and other causes of action. The complaint seeks recovery of damages sustained by Quantum arising from the allegations, as well as fees and costs incurred.
Another shareholder derivative complaint was filed in the same court on November 4, 2025. That complaint names Felicia Marti on behalf of Quantum Corporation as the plaintiff, with James J. Lerner, Kenneth P. Gianella, Laura Nash, John Fichthorn, Donald J. Jaworski, Hugues Meyrath, John R. Tracy, and Emily White named as defendants. The complaint substantially repeats the allegations of the Cullison derivative litigation and seeks relief of recovery of damages sustained by Quantum arising from the allegations, certain corporate governance reforms, and fees and costs incurred.

The court ordered the separate Cullison and Marti shareholder derivative complaints to be consolidated and stayed pending further activity in the shareholder class action litigation.
To date, no additional substantive activity has occurred. As a result, the case has not progressed enough to support an opinion on potential outcomes or the possibility that damages could be awarded. At this time, Quantum is not able to determine whether the consolidated lawsuits would have any material impact on our business, operating results, or financial condition.

Leases
At September 30, 2026 and March 31, 2026, the Company had various non-cancelable operating leases for office facilities. Refer to Note 5: Leases, for additional information regarding lease commitments.
NOTE 11: FAIR VALUE OF FINANCIAL INSTRUMENTS
The Company follows the guidance in ASC 820, Fair Value Measurement, for its financial assets and liabilities that are re-measured and reported at fair value at each reporting period and non-financial assets and liabilities that are re-measured and reported at fair value at least annually. The Company has certain non-financial assets that are measured at fair value on a non-recurring basis when there is an indicator of impairment, and they are recorded at fair value only when an impairment is recognized. These assets include property and equipment and amortizable intangible assets. The Company did not record impairments to any non-financial assets during the three and six months ended September 30, 2026 and 2025.

The carrying amounts reported in the accompanying condensed consolidated financial statements for cash and cash equivalents, restricted cash, accounts receivable, accounts payable and other current liabilities approximate their respective fair values because of the short-term nature of these accounts.
Debt
The fair value of the Company’s debt was estimated using a discounted cash flow approach based on the Company’s current borrowing rates for similar types of debt instruments, adjusted for credit and nonperformance risk. The Company uses significant other observable market data and assumptions (Level 2 inputs, as defined in ASC 820, Fair Value Measurement) that it believes market participants would use in pricing such debt.

The carrying value and estimated fair value of the Company’s debt were as follows (in thousands):

On June 4, 2026, the Company paid the entire outstanding principal amount and terminated the Term Loan Credit Agreement, see Note 4 : Debt for further details,
Warrants
Forbearance Warrant
On September 23, 2025, the Company established the initial fair value for the Forbearance Warrant issued to Dialectic in connection with the Fifteenth Amendment, which allows the purchase of up to 2,653,308 shares of Common Stock at an exercise price of $8.81. The fair value was subsequently remeasured as of September 30, 2026 and March 31, 2026, and the resulting changes in fair value were recognized in the condensed consolidated statements of operations and comprehensive loss under “Change in fair value of warrant liabilities”.

The Forbearance Warrant was valued using a Monte Carlo simulation model in conjunction with a Probability-Weighted Expected Return Model. This model incorporates various assumptions, including the Company’s common stock price, expected volatility, risk-free interest rate, and the remaining contractual term of the warrant.

Because the valuation relies on significant unobservable inputs, the fair value of the Forbearance Warrant is classified as Level 3 within the fair value hierarchy (as defined in ASC 820, Fair Value Measurement).

The following table summarizes the key assumptions used in estimating the fair value of the Forbearance Warrant at September 30, 2026 and March 31, 2026:

(1) Scenario probability at March 31, 2026 was based on timing expectations of management that a liquidation event occurring was estimated at 15%; a fundamental transaction occurring was estimated at 15%; and none of the previous events were estimated at 70%. Scenario probability at September 30, 2026 incorporated a 10% of a liquidation event occurring; a 15% of a fundamental transaction occurring; and none of the previous events were estimated at 75%.

Conversion Warrant
On June 1, 2026, the Company issued to Dialectic a warrant (the “Conversion Warrant”) to purchase up to 105,911 shares of Common Stock at an exercise price of $5.1940. The Company established the initial fair value for the Conversion Warrant issued to Dialectic in connection with the Sixteenth Amendment. The fair value was subsequently remeasured as of September 30, 2026, and the resulting change in fair value was recognized in the condensed consolidated statement of operations and comprehensive loss under “Change in fair value of warrant liabilities.”
The Conversion Warrant was valued using a Monte Carlo simulation model in conjunction with a Probability-Weighted Expected Return Model. This model incorporates various assumptions, including the Company’s common stock price, expected volatility, risk-free interest rate, and the remaining contractual term of the warrant.

Because the valuation relies on significant unobservable inputs, the fair value of the Conversion Warrant is classified as Level 3 within the fair value hierarchy (as defined in ASC 820, Fair Value Measurement). Significant changes in the Company's stock price, volatility, or changes in the key assumptions stated below could result in a significantly higher or lower fair value of the warrant liabilities.

The following table summarizes the key assumptions used in estimating the fair value of the Conversion Warrant at issuance and at September 30, 2026:
September 30, 2026June 1, 2026
Discount period (years)4.67 years5 years
Risk-free interest rate

Probability1
10% - 15% - 75%
10% - 15% - 75%
Fair value (in thousands)$3,255$1,280

(1) Scenario probability as of issuance and at September 30, 2026 was based on timing expectations of management that a liquidation event occurring was estimated at 10%; a fundamental transaction occurring was estimated at 15%; and none of the previous events were estimated at 75%.

Product Revenue
In the three months ended September 30, 2026, product revenue increased $27.2 million, or 77%, as compared to the same period in fiscal 2026. The primary driver of this increase was strong demand across all secondary storage product lines including Scalar tape storage products, ActiveScale object storage appliances, and DXi backup appliances. Overall, secondary storage revenue increased by $25.0 million, or 126.2% as compared to the same period in fiscal 2026. Devices and media revenues also increased by $4.0 million, or 53.2% as compared to fiscal 2026. These increases were partially offset by declines in primary storage.
Service and Subscription Revenue
Service and subscription revenue remained flat with a small decrease of $0.6 million, or 2%, in the three months ended September 30, 2026, compared to the same period in fiscal 2026.
Royalty Revenue
We receive royalties from third parties that license our linear-tape open media patents through our membership in the linear-tape open consortium. Royalty revenue increased $0.3 million, or 18%, in the three months ended September 30, 2026, as compared to the same period in fiscal 2026, related to higher overall unit shipments.

Product gross margin increased by 1,400 basis points for the three months ended September 30, 2026, as compared to fiscal 2026. Majority of the increase is tied to higher volume of core products with better blended margin mix and increased average selling prices, and benefit from proactively managing our supply chain ahead of supplier price increases.

Income tax provision for the three months ended September 30, 2026 and 2025 is primarily influenced by foreign and state income taxes.

Due to our history of net losses in the United States, the protracted period for utilizing tax attributes uncertain foreign jurisdictions, and the difficulty in predicting future results, we believe that we cannot rely on projections of future taxable income to realize most of our deferred tax assets. Accordingly, we have established a full valuation allowance against our U.S. and certain foreign net deferred tax assets. Significant management judgment is required in assessing our ability to realize any future benefit from our net deferred tax assets. We intend to maintain this valuation allowance until sufficient positive evidence exists to support its reversal. Our income tax expense recorded in the future will be reduced to the extent that sufficient positive evidence materializes to support a reversal of, or decrease in, our valuation allowance.

The change in other income (expense), net during the six months ended September 30, 2026 compared with the same period in fiscal 2026 was related to increase in interest income partially offset by fluctuations in foreign currency exchange rates during the six months ended September 30, 2026.

Income Taxes

(dollars in thousands)2026% of pretax income2025% of pretax income$ Change% Change
Income tax provision$855 — %$380 (1)%$475 125 %
The income tax provision for the six months ended September 30, 2026 and 2025 is primarily influenced by foreign and state income taxes. Due to our history of net losses in the United States, the protracted period for utilizing tax attributes in certain foreign jurisdictions, and the difficulty in predicting future results, we believe that we cannot rely on projections of future taxable income to realize most of our deferred tax assets. Accordingly, we have established a full valuation allowance against our U.S. and certain foreign net deferred tax assets. Significant management judgment is required in assessing our ability to realize any future benefit from our net deferred tax assets. We intend to maintain this valuation allowance until sufficient positive evidence exists to support its reversal. Our income tax expense recorded in the future will be reduced to the extent that sufficient positive evidence materializes to support a reversal of, or decrease in, our valuation allowance.

Liquidity and Capital Resources
We consider liquidity in terms of the sufficiency of internal and external cash resources to fund our operating, investing and financing activities. Our principal sources of liquidity include cash from operating activities, cash and cash equivalents on our balance sheet and proceeds from the sale of common stock. We require significant cash resources to provide for our research and development activities, fund our working capital needs, and make capital expenditures. Our future liquidity requirements will depend on multiple factors, including our research and development plans and capital investment needs. We believe our existing cash and cash equivalents and cash flows from operations will be sufficient to fund our operations, working capital and capital expenditure needs for at least the next 12 months.

We had cash and cash equivalents of $67.4 million as of September 30, 2026, which excludes $0.1 million of short-term restricted cash. Our total outstanding Term Loan debt was fully repaid in the first quarter of fiscal 2027.

We generated cash flows from operations of approximately $14.3 million for the six months ended September 30, 2026, compared to negative cash flows of $32.5 million for the six months ended September 30, 2025. We generated net losses of approximately $200.1 million and $63.7 million for the six months ended September 30, 2026 and 2025, respectively. We have funded operations through the sale of common stock and debt borrowings as described in Note 4: Debt and Note 7 : Common Stock.

million. The improvement was primarily driven by improved operating results, lower cash interest paid following the repayment of the Term Loan in June 2026, and favorable changes in deferred revenue and accounts payable.
Net Cash Used in Investing Activities
Net cash used in investing activities was $0.6 million and $1.6 million for the six months ended September 30, 2026 and 2025, respectively, consisting of capital expenditures.
Net Cash Provided by Financing Activities
Net cash provided by financing activities was $37.6 million for the six months ended September 30, 2026, primarily due to $94.3 million of net Private Placement proceeds, partially offset by $56.8 million of Term Loan repayments. Net cash provided by financing activities of $32.8 million for the six months ended September 30, 2025 was primarily due to $67.0 million of SEPA proceeds, partially offset by net debt repayments.
Commitments and Contingencies
Our contingent liabilities consist primarily of certain financial guarantees, both express and implied, related to product liability and potential infringement of intellectual property. We have little history of costs associated with such indemnification requirements and contingent liabilities associated with product liability may be mitigated by our insurance coverage. In the normal course of business to facilitate transactions of our services and products, we indemnify certain parties with respect to certain matters, such as intellectual property infringement or other claims. We also have indemnification agreements with our current and former officers and directors. It is not possible to determine the maximum potential amount under these indemnification agreements due to the limited history of our indemnification claims, and the unique facts and circumstances involved in each particular agreement. Historically, payments made by us under these agreements have not had a material impact on our operating results, financial position or cash flows.

We are also subject to ordinary course of business litigation, See Note 10: Commitments and Contingencies, to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

CRITICAL ACCOUNTING ESTIMATES AND POLICIES
The preparation of our condensed consolidated financial statements in accordance with GAAP requires management to make judgments, estimates and assumptions that affect the amounts reported in the condensed consolidated financial statements and accompanying notes included elsewhere in this Quarterly Report. On an ongoing basis, we evaluate estimates, which are based on historical experience and on various other assumptions that we believe to be reasonable under the circumstances. We consider certain accounting policies to be critical to understanding our financial statements because the application of these policies requires significant judgment on the part of management, which could have a material impact on our financial statements if actual performance should differ from historical experience or if our assumptions were to change. Our accounting policies that include estimates that require management’s subjective or complex judgments about the effects of matters that are inherently uncertain are summarized in the Annual Report under the section entitled “Management’s Discussion and Analysis of Financial Condition and Results of Operations—Critical Accounting Estimates and Policies”. Other than the elimination of the fair value of the Convertible Note as a critical accounting estimate following its conversion on June 4, 2026, and the inclusion of the Conversion Warrant, issued on June 1, 2026, within our estimate of the fair value of warrant liabilities, there have been no material changes to our critical accounting estimates and policies during the six months ended September 30, 2026 from those disclosed in the Annual Report. For additional information on our significant accounting policies, see Note 1 to our unaudited condensed consolidated financial statements included elsewhere in this Quarterly Report.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
There have been no material changes to our quantitative and qualitative disclosures about market risk from those described under “Management’s Discussion and Analysis of Financial Condition and Results of Operations” included in the Annual Report, which such section is incorporated herein by reference.
ITEM 4. CONTROLS AND PROCEDURES
Limitations on Effectiveness of Controls and Procedures
In designing and evaluating our disclosure controls and procedures, management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving the desired control objectives. In addition, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and that management is required to apply judgment in evaluating the benefits of possible controls and procedures relative to their costs.
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Principal Financial Officer, has evaluated the effectiveness of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934 (the “Exchange Act”), as of the end of the period covered by this Quarterly Report. Based on this evaluation, our Chief Executive Officer and Principal Financial Officer concluded that our disclosure controls and procedures were not effective due to material weaknesses in internal control over financial reporting related to revenue recognition, inventories, income taxes and control environment as previously described in Part II, Item 9A of our Annual Report on Form 10-K for the fiscal year ended March 31, 2026, which remain unremediated as of September 30, 2026.

Notwithstanding the identified material weaknesses, management, including our Chief Executive Officer and Principal Financial Officer, have determined, based on the procedures performed, that the condensed consolidated financial statements included in this Quarterly Report on Form 10-Q fairly present in all material respects the financial condition, results of operations and cash flows of the Company for the periods presented in accordance with U.S. generally accepted accounting principles.
Remediation Update
Management has initiated and continues to implement a remediation plan designed to address the material weaknesses described above. Remediation activities in the quarter ended September 30, 2026 include:

•Engaging an independent third-party consulting firm with expertise in internal controls over financial reporting, revenue recognition, inventory accounting, and Sarbanes-Oxley compliance to assist management in evaluating control deficiencies, designing enhanced controls, and supporting remediation efforts;
•We continued to implement enhanced controls over sales order entry, contract review, deferral schedule maintenance, and standalone selling price analyses to support compliance with ASC 606;
•We enhanced inventory count, reconciliation, and monitoring procedures, including enhanced controls over the reconciliation of physical inventory records to underlying system records;
•We began implementing enhanced controls over the preparation and review of the income tax provision and related tax accounts and disclosures by implementing a formalized preparation and review process.
•We enhanced the accounting and finance organization through the addition of personnel with public company financial reporting, revenue recognition, inventory accounting, and income tax expertise. During the second quarter, we hired a Director of Tax and a Chief Accounting Officer who is a certified public accountant with prior public company financial reporting experience.

While management has begun implementing these remediation measures, the material weaknesses cannot be considered remediated until the enhanced controls have been fully designed, implemented, operated for a sufficient period of time, and management has completed testing and concluded that the controls are operating effectively.
Changes in Internal Controls over Financial Reporting
Except for the matters discussed above, there were no changes in our internal controls over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) identified in connection with the evaluation of our

internal control performed during the fiscal quarter ended September 30, 2026, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
