AMERICAN SUPERCONDUCTOR CORPORATION
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS
1. Nature of the Business and Operations
Nature of the Business and Operations
American Superconductor Corporation (together with its subsidiaries, “AMSC®” or the “Company”) was founded on April 9, 1987. The Company is a leading system provider of megawatt-scale power resiliency solutions that orchestrate the rhythm and harmony of power on the grid™ and protect and expand the capability of the Navy’s fleet. The Company’s system level products leverage its proprietary “smart materials” and “smart software and controls” to provide enhanced resiliency and improved performance of megawatt-scale power flow.
These unaudited condensed consolidated financial statements of the Company have been prepared on a going concern basis in accordance with United States generally accepted accounting principles (“GAAP”) and the Securities and Exchange Commission’s (“SEC”) instructions to Form 10-Q. All significant intercompany accounts and transactions are eliminated in consolidation. Investments in entities in which we do not have a controlling interest are accounted for under the equity method of accounting. The going concern basis of presentation assumes that the Company will continue operations and will be able to realize its assets and discharge its liabilities and commitments in the normal course of business. Certain information and footnote disclosures normally included in the condensed consolidated financial statements prepared in accordance with GAAP have been omitted pursuant to those instructions. The year-end balance sheet data was derived from audited financial statements but does not include all disclosures required by GAAP. The unaudited condensed consolidated financial statements, in the opinion of management, reflect all adjustments (consisting of normal recurring adjustments) necessary for a fair statement of the results for the interim periods ended December 31, 2025 and 2024, and the financial position at December 31, 2025; however, these results are not necessarily indicative of results which may be expected for the full year. The interim condensed consolidated financial statements, and notes thereto, should be read in conjunction with the audited condensed consolidated financial statements for the year ended March 31, 2025, and notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2025 filed with the SEC on May 21, 2025.
2. Acquisition
Acquisition of Comtrafo
On December 5, 2025 (the "Comtrafo Acquisition Date"), the Company entered into a Stock Exchange Agreement (the “Stock Exchange Agreement”) with the selling stockholders named therein. Pursuant to the terms of the Stock Exchange Agreement and concurrently with entering into such agreement, the Company acquired all of the issued and outstanding shares of capital stock of Comtrafo Indústria de Transformadores Elétricos S.A. ("Comtrafo") (the "Comtrafo Acquisition"). Comtrafo is a Brazil-based manufacturer of large power and distribution transformers primarily for utility customers and also for industrial customers.
The Comtrafo Acquisition has been accounted for under the purchase method of accounting in accordance with ASC 805, Business Combinations. The Company allocated the purchase price on a preliminary basis using the information available as of December 31, 2025 to the assets acquired and liabilities assumed at their estimated fair values as of the date of acquisition. Due to the timing of the completion of the acquisition, the purchase price and related allocation are preliminary and could be revised as a result of adjustments made to the purchase price, and additional information obtained regarding assets acquired and liabilities assumed and revisions of provisional estimates of fair values, including, but not limited to the completion of independent appraisals of inventory, customer relationships, backlog, deferred taxes, tangible assets and intangible assets. Changes to the purchase price allocation could be significant. The purchase price allocation will be finalized within the measurement period of up to one year from the acquisition. The excess of the purchase price paid by the Company over the estimated fair value of net assets acquired has been recorded as goodwill.

3. Revenue Recognition
The Company’s revenues in its Grid segment are derived primarily through enabling the transmission and distribution of power, providing planning services that allow it to identify power grid needs and risks, and developing ship protection systems for the U.S. Navy. The Company’s revenues in its Wind segment are derived primarily through supplying advanced power electronics and control systems, licensing its highly engineered wind turbine designs, and providing extensive customer support services to wind turbine manufacturers. The Company records revenue based on a five-step model in accordance with Accounting Standards Codification ("ASC") 606. For its customer contracts, the Company identifies the performance obligations, determines the transaction price, allocates the contract transaction price to the performance obligations, and recognizes the revenue when (or as) control of goods or services is transferred to the customer. For the three and nine months ended December 31, 2025,
In the Company's equipment and system product line, each contract with a customer summarizes each product sold to a customer, which typically represents distinct performance obligations. A contract's transaction price is allocated to each distinct performance obligation using the respective standalone selling price which is determined primarily using the cost-plus expected margin approach and recognized as revenue when, or as, the performance obligation is satisfied. The majority of the Company’s product sales transfer control to the customer in line with the contracted delivery terms and revenue is recorded at the point in time when title and risk transfer to the customer, which is primarily upon delivery, as the Company has determined that this is the point in time that control transfers to the customer.
In the Company's service and technology development product line, there are several different types of transactions and each begins with a contract with a customer that summarizes each product sold to a customer, which typically represents distinct performance obligations. The technology development transactions are primarily for activities that have no alternative use and for which a profit can be expected throughout the life of the contract. In these cases, the revenue is recognized over time, but in the instances where the profit cannot be assured throughout the entire contract then the revenue is recognized at a point in time. Each contract's transaction price is allocated to each distinct performance obligation using the respective standalone selling price which is determined primarily using the cost-plus expected margin approach. The ongoing service transactions are for service contracts that provide benefit to the customer simultaneously as the Company performs its obligations, and therefore this revenue is recognized ratably over time throughout the effective period of these contracts. The transaction prices on these contracts are allocated based on an adjusted market approach which is re-assessed annually for reasonableness. The field service transactions include contracts for delivery of goods and completion of services made at the customer's requests, which are not deemed satisfied until the work has been completed and/or the requested goods have been delivered, so all of this revenue is recognized at the point in time when the control changes, and at allocated prices based on the adjusted market approach driven by standard price lists. The royalty transactions are related to certain contract terms on transactions in the Company's equipment and systems product line based on activity as specified in the contracts. The transaction prices of these agreements are calculated based on an adjusted market approach as specified in the contract. The Company reports royalty revenue for usage-based royalties when the sales have occurred. In circumstances when collectability is not assured and a contract does not exist under ASC 606, revenue is deferred until a non-refundable payment has been received for substantially all the amount that is due and there are no further remaining performance obligations.
The Company's service contracts can include a purchase order from a customer for specific goods in which each item is a distinct performance obligation satisfied at a point in time at which control of the goods is transferred to the customer. This transfer occurs based on the contracted delivery terms or when the requested service work has been completed. The transaction price for these goods is allocated based on the adjusted market approach considering similar transactions under similar circumstances. Service contracts are also derived from ongoing maintenance contracts and extended service-type warranty contracts. In these transactions, the Company is contracted to provide an ongoing service over a specified period of time. As the customer is consuming the benefits as the service is being provided, the revenue is recognized over time ratably.
The Company’s policy is not to accept volume discounts, product returns, or rebates and allowances within its contracts. In the event a contract was approved with any of these terms, it would be evaluated for variable consideration, estimated and recorded as a reduction of revenue in the same period the related product revenue was recorded.
The Company provides assurance-type warranties on all product sales for a term of typically to years, and extended service-type warranties are available for purchase at the customer's option for an additional term ranging up to additional years. The Company accrues for the estimated warranty costs for assurance warranties at the time of sale based on historical warranty experience plus any known or expected changes in warranty exposure. For all extended service-type warranties, the Company recognizes the revenue ratably over time during the effective period of the services.
Infrequently, the Company receives requests from customers to hold product being purchased from us for a valid business purpose. The Company recognizes revenues for such arrangements provided the transaction meets, at a minimum, the following criteria: the reason for the bill-and-hold arrangement must be substantive; the product must be identified separately as belonging to the customer; the product currently must be ready for physical transfer to the customer; the entity cannot have the ability to use the product or to direct it to another customer. Revenue for the nine months ended December 31, 2025 included $
The Company records revenue net of sales tax, value added tax, excise tax and other taxes collected concurrent with revenue-producing activities. The Company has elected to recognize the cost for freight and shipping when control over the products sold passes to customers and revenue is recognized. The Company has elected to recognize incremental costs of obtaining a contract as expense when incurred except in contracts where the amortization period would exceed twelve months. As of December 31, 2025 and March 31, 2025, the Company's capitalized incremental contract costs were not material. The Company has elected not to adjust the promised amount of consideration for the effects of a significant financing component if the period of financing is twelve months or less. The Company has elected to recognize revenue based on the as invoiced practical expedient if there is a right to consideration from a customer in an amount that corresponds directly with the value of the Company's performance.
The Company’s contracts with customers do not typically include extended payment terms and may include milestone billing over the life of the contract. Payment terms vary by contract type and type of customer and generally range from to days from delivery.

5. Computation of Net Income per Share of Common Stock
Basic net income per share (“EPS”) is computed by dividing net income by the weighted-average number of common shares outstanding for the period. Where applicable, diluted EPS is computed by dividing the net income by the weighted-average number of common shares and dilutive common equivalent shares outstanding during the period, calculated using the treasury stock method. Common equivalent shares include the effect of restricted stock, exercise of stock options and warrants and contingently issuable shares. Stock options and warrants that are out-of-the-money with exercise prices greater than the average market price of the underlying common shares and shares of performance-based restricted stock where the contingency was not met are excluded from the computation of diluted EPS as the effect of their inclusion would be anti-dilutive. For the three months ended December 31, 2025,

Goodwill
Goodwill represents the difference between the purchase price and the fair value of the identifiable tangible and intangible net assets when accounted for using the purchase method of accounting. Goodwill is not amortized but reviewed for impairment. The Company's goodwill balance relates to the Comtrafo Acquisition in fiscal 2025, the NWL Acquisition in fiscal 2024, the acquisition of Neeltran, Inc. in fiscal 2021, the Northeast Power Systems, Inc. ("NEPSI") acquisition in fiscal 2020, and the acquisition of Infinia Technology Corporation in fiscal 2017 and is reported in the Grid business segment. Goodwill is reviewed annually on February 28th and whenever events or changes in circumstances indicate that the carrying value of the goodwill might not be recoverable. Goodwill increased by $

7. Fair Value Measurements
A valuation hierarchy for disclosure of the inputs to valuation used to measure fair value has been established. This hierarchy prioritizes the inputs into three broad levels as follows:
| Level 1 | - | Inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. |
|
|
|
|
| Level 2 | - | Inputs include quoted prices for similar assets and liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability, and inputs that are derived principally from or corroborated by observable market data by correlation or other means (market corroborated inputs). |
|
|
|
|
| Level 3 | - | Unobservable inputs that reflect the Company’s assumptions that market participants would use in pricing the asset or liability. The Company develops these inputs based on the best information available, including its own data. |
The Company provides a gross presentation of activity within Level 3 measurement roll-forward and details of transfers in and out of Level 1 and 2 measurements. A change in the hierarchy of an investment from its current level is reflected in the period during which the pricing methodology of such investment changes. Disclosure of the transfer of securities from Level 1 to Level 2 or Level 3 is made in the event that the related security is significant to total cash and investments. The Company did not have any transfers of assets and liabilities from Level 1, Level 2 or Level 3 of the fair value measurement hierarchy during the three or nine months ended December 31, 2025.
A financial asset’s or liability’s classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement.
Valuation Techniques
Cash Equivalents
Cash equivalents consist of highly liquid instruments with maturities of three months or less that are regarded as high quality, low risk investments and are measured using such inputs as quoted prices, and are classified within Level 1 of the valuation hierarchy. Cash equivalents consist principally of money market accounts.
Short-term Cash Instruments
Short-term cash instruments consist of highly liquid instruments with maturities of three months or less that are regarded as high quality, low risk investments and are measured using such inputs as quoted prices in markets that are not active, and are classified within Level 2 of the valuation hierarchy. Short-term cash instruments consist principally of certificates of deposits.
Contingent Consideration
Contingent consideration relates to the earnout payment set forth in the Stock Exchange Agreement governing the acquisition of Comtrafo that provides the selling stockholders may receive an additional sum of cash upon the achievement of certain specified earnings before interest, taxes, depreciation, and amortization ("EBITDA") objectives during the three years following the Comtrafo Acquisition Date. See Note 14, "Contingent Consideration" for further discussion. The Company relied on a Monte Carlo method to determine the fair value of the contingent consideration on the closing of the acquisition of Comtrafo and continues to revalue the fair value of the contingent consideration using the same method at each subsequent balance sheet date until the contingencies are resolved and the cash to be paid is determined, with the change in fair value recorded in the current period operating loss. For the period ended December 31, 2025, the change in fair value from December 5, 2025 was not considered material and as such no adjustment was recorded.

On a quarterly basis, the Company reassesses the valuation allowance on deferred income tax assets, weighing positive and negative evidence to assess the recoverability of the deferred tax assets. As of December 31, 2025, the Company recorded a $
On July 4, 2025, the reconciliation bill, commonly referred to as the One Big Beautiful Bill ("OBBB") was signed into law, which includes a broad range of tax reform provisions that may affect the company's financial results. The OBBB allows an elective deduction for domestic Research and Development (R&D), a reinstatement of elective 100% first-year bonus depreciation, and a more favorable tax rate on Foreign-derived Deduction Eligible Income and income from non-U.S. subsidiaries (Net CFC Tested Income), among other provisions. The Company has performed an initial evaluation of the impact of the OBBB on the Company's effective tax rate and deferred tax assets in 2025 and future periods. Based on this initial evaluation, the Company believes the tax reform provisions will not have a material impact on the Company’s consolidated financial statements and related disclosures. We will continue to assess the implications of the OBBB, and our tax provision may be further impacted as additional guidance from the U.S. Department of the Treasury is released.
Accounting for income taxes requires a two-step approach to recognizing and measuring uncertain tax positions. The first step is to evaluate the tax position for recognition by determining if, based on the technical merits, it is more likely than not the position will be sustained upon audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely to be realized upon ultimate settlement. The Company re-evaluates these uncertain tax positions on a quarterly basis. The evaluation is based on factors including, but not limited to, changes in facts or circumstances, changes in tax law, effectively settled issues under audit and new audit activity. Any changes in these factors could result in the recognition of a tax benefit or an additional charge to the tax provision. The Company did identify any uncertain tax positions in the nine months ended December 31, 2025 and did have any gross unrecognized tax benefits as of December 31, 2025.
14. Contingent Consideration
NEPSI Contingent Consideration
On October 1, 2020 (the "NEPSI Acquisition Date"), the Company entered into a Stock Purchase Agreement (the "NEPSI Stock Purchase Agreement") with the selling stockholders named therein. Pursuant to the terms of the NEPSI Stock Purchase Agreement and concurrently with entering into such agreement, the Company acquired all of the issued and outstanding (i) shares of capital stock of NEPSI, and (ii) membership interests of Northeast Power Realty, LLC, a New York limited liability company, which holds the real property that serves as NEPSI's headquarters (the "NEPSI Acquisition"). NEPSI is a U.S.-based global provider of medium-voltage metal-enclosed power capacitor banks and harmonic filter banks for use on electric power systems. NEPSI is a wholly-owned subsidiary of the Company and is operated by its Grid business segment. The purchase price was $
The Company evaluated the NEPSI Acquisition earnout payment set forth in the NEPSI Stock Purchase Agreement, which was expected to require settlement in the Company's common stock, and determined the contingent consideration qualified for liability classification and derivative treatment under ASC 815, Derivatives and Hedging. As a result, for the periods in which the Company had outstanding contingent consideration, the fair value of the contingent consideration was remeasured and the resulting gain or loss was recognized in operating expenses until the share amount was fixed.
Following is a summary of the key assumptions used in a Monte Carlo simulation to calculate the fair value of contingent consideration related to the NEPSI Acquisition:

Comtrafo Contingent Consideration
On December 5, 2025, the Company entered into the Stock Exchange Agreement with the selling stockholders named therein. Pursuant to the terms of the Stock Exchange Agreement, the Company has agreed to pay the selling stockholders of the Comtrafo Acquisition an additional amount in cash upon the achievement of specified EBITDA objectives during the three years following the Comtrafo Acquisition Date. The Company evaluated the Comtrafo Acquisition earnout payment set forth in the Comtrafo Stock Exchange Agreement (See Note 2, "Acquisitions" for further details), which will require settlement in cash, and determined the contingent consideration qualified for liability classification. As a result, for each period, the fair value of the contingent consideration will be remeasured, and the resulting gain or loss will be recognized until the cash amount is fixed.
Following is a summary of the key assumptions used in a Monte Carlo simulation to calculate the fair value of contingent consideration related to the Comtrafo Acquisition:
| December 05, | ||||
| Fiscal Year 2025 | 2025 | |||
| EBITDA Risk Premium (continuous) | % | |||

16. Leases
Operating Leases
All significant lease arrangements are recognized at lease commencement. Operating lease right–of-use assets and lease liabilities are recognized at commencement. The operating lease right-of-use asset includes any lease payments related to initial direct cost and prepayments and excludes any lease incentives. Lease expense is recognized on a straight-line basis over the lease term. The Company enters into a variety of operating lease agreements through the normal course of its business, but primarily real estate leases to support its operations. The real estate lease agreements generally provide for fixed minimum rental payments and the payment of real estate taxes and insurance. Many of these real estate leases have one or more renewal options that allow the Company, at its discretion, to renew the lease for varying periods up to years or to terminate the lease. Only renewal options or termination rights that the Company believed were likely to be exercised were included in the lease calculations.
The Company also enters into leases for vehicles, IT equipment and service agreements, and other leases related to its manufacturing operations that are also included in the right-of-use assets and lease liability accounts if they are for a term of longer than twelve months. However, many of these leases are either short-term in nature or immaterial. The Company has made the policy election to exclude short-term leases from the condensed consolidated balance sheets.

17. Commitments and Contingencies
Legal Contingencies
From time to time, the Company is involved in legal and administrative proceedings and claims of various types. The Company records a liability in its condensed consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. The Company reviews these estimates each accounting period as additional information is known and adjusts the loss provision when appropriate. If a matter is both probable to result in a liability and the amounts of loss can be reasonably estimated, the Company estimates and discloses the possible loss or range of loss to the extent necessary to make the condensed consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its condensed consolidated financial statements.

18. Business Segments
The Company reports its financial results in reportable business segments: Grid and Wind. In accordance with ASC 280, Segment Reporting, the Company has identified operating segments. The Company's operating segments reflect the way in which internally-reported financial information is used to make decisions and allocate resources.
Through the Company’s power grid offerings, the Grid business segment enables electric utilities, industrial facilities, and renewable energy project developers to connect, transmit and distribute smarter, cleaner and better power through its transmission planning services, power electronics, and superconductor-based systems. The sales process is enabled by transmission planning services that allow it to identify power grid congestion, poor power quality and other risks, which helps the Company determine how its solutions can improve network performance. These services often lead to sales of grid interconnection solutions for wind farms and solar power plants, power quality systems, and transmission and distribution cable systems. The Company also sells ship protection products to the U.S. Navy through its Grid business segment.
Through the Company’s wind power offerings, the Wind business segment enables manufacturers to field highly competitive wind turbines through its advanced power electronics and control system products, engineered designs, and support services. The Company supplies advanced power electronics and control systems, licenses its highly engineered wind turbine designs, and provides extensive customer support services to wind turbine manufacturers. The Company’s design portfolio includes a broad range of drive trains and power ratings of 2 megawatts ("MWs") and higher. The Company provides a broad range of power electronics and software-based control systems that are highly integrated and designed for optimized performance, efficiency, and grid compatibility.
AMSC’s Chief Executive Officer Daniel McGahn is the chief operating decision maker. The chief operating decision maker uses segment operating income (loss) to allocate resources (including employees, property, and financial or capital resources) for each segment predominantly in the annual budget and forecasting process. The chief operating decision maker considers budget-to-actual variances on a monthly basis for segment operating income (loss) when making decisions about allocating capital and personnel to the segments. The chief operating decision maker also uses segment operating income or loss to assess the performance for each segment by comparing the results and return on assets of each segment with one another and in the compensation of certain employees.
The following tables (i) summarize total sales by segment and (ii) reconcile each segment's sales to their respective segment operating income, including segment operating expenses, for each of the three and nine months ended December 31, 2025 and 2024 (in thousands):

The accounting policies of the business segments are the same as those for the consolidated Company. The Company’s business segments have been determined in accordance with the Company’s internal management structure, which is organized based on operating activities. The Company evaluates performance based upon several factors, of which the primary financial measures are segment revenues and segment operating income (loss). The disaggregated financial results of the segments reflect allocation of certain functional expense categories consistent with the basis and manner in which Company management internally disaggregates financial information for the purpose of assisting in making internal operating decisions. In addition, certain corporate expenses which the Company does not believe are specifically attributable or allocable to either of the two business segments have been excluded from the segment operating income (loss).

All other brand names, product names, trademarks or service marks appearing in this Quarterly Report on Form 10-Q are the property of their respective holders.
Executive Overview
We are a leading system provider of megawatt-scale power resiliency solutions that orchestrate the rhythm and harmony of power on the grid™, and protect and expand the capability of our Navy's fleet. Our solutions enhance the performance of the power grid, protect our Navy’s fleet, and lower the cost of wind power. In the power grid market, we enable electric utilities, industrial facilities, and renewable energy project developers to connect, transmit and distribute smarter, cleaner and better power through our transmission planning services and power electronics and superconductor-based systems. In the wind power market, we enable manufacturers to field highly competitive wind turbines through our advanced power electronics and control system products, engineering, and support services. Our power grid and wind products and services provide exceptional reliability, security, efficiency and affordability to our customers.
Our power system solutions help to improve energy efficiency, alleviate power grid capacity constraints, improve system resiliency, and increase the adoption of renewable energy generation. Demand for our solutions is driven by the growing needs for modernized smart grids that improve power reliability, security and quality, the U.S. Navy's effort to upgrade onboard power systems to support fleet electrification, and the needs for increased renewable sources of electricity, such as wind and solar energy. Concerns about these factors have led to increased spending by corporations and the military, as well as supportive government regulations and initiatives on local, state, and national levels, including renewable portfolio standards, tax incentives and international treaties.
We manufacture products using two proprietary core technologies: PowerModule™ programmable power electronic converters and our Amperium® high temperature superconductor ("HTS") wires. These technologies and our system-level solutions are protected by a robust intellectual property portfolio consisting of patents and patent applications worldwide and rights through exclusive and non-exclusive licenses.
We operate our business under two market-facing business segments: Grid and Wind. We believe this market-centric structure enables us to more effectively anticipate and meet the needs of power generation project developers, the Navy's ship protection systems, electric utilities and wind turbine manufacturers.

Our fiscal year begins on April 1 and ends on March 31. When we refer to a particular fiscal year, we are referring to the fiscal year that began on April 1 of that same year. For example, fiscal 2025 refers to the fiscal year that began on April 1, 2025. Other fiscal years follow similarly.
Changes in macroeconomic conditions arising from various reasons, such as the ongoing war between Russia and Ukraine, tariffs, trade restrictions and resulting trade conflicts, labor force availability, sourcing, material delays and global supply chain disruptions, could have a material adverse effect on our business, financial condition and results of operations.
On December 5, 2025 (the "Comtrafo Acquisition Date"), we entered into a Stock Exchange Agreement (the "Stock Exchange Agreement") with the selling stockholders named therein (the "Stockholders"). Pursuant to the terms of the Stock Exchange Agreement, Mardin Participações Ltda., an entity incorporated in Brazil (“AMSC Brazil”) and our wholly-owned subsidiary, directly or indirectly, purchased all of the issued and outstanding shares of Comtrafo Indústria de Transformadores Elétricos S.A. ("Comtrafo") (collectively, the "Comtrafo Acquisition") for (a) (i) 300,000,000 Brazilian Real in cash; and (b) 2,417,142 restricted shares of our common stock, $0.01 par value per share (the "AMSC Shares") that were paid and issued, respectively, at closing. In addition, pursuant to certain additional real property agreements, AMSC Brazil through Comtrafo purchased certain real estate assets and transportation assets of Comtrafo for 155,564,538 Brazilian Real and 13,376,676 Brazilian Real, respectively, in cash. Additionally, AMSC Brazil has agreed to pay the Stockholders up to an additional 382,500,000 Brazilian Real in cash (the "Earnout") upon the achievement of specified earnings before interest, taxes, depreciation, and amortization ("EBITDA") objectives during the three years following the closing. Comtrafo is a Brazil-based manufacturer of large power and distribution transformers primarily for utility customers and also for industrial customers.
On August 1, 2024, we entered into a Stock Purchase Agreement (the “Stock Purchase Agreement”) with the selling stockholders named therein. Pursuant to the terms of the Stock Purchase Agreement and concurrently with entering into such agreement, we acquired all of the issued and outstanding shares of Megatran, Industries, Inc. ("Megatran"), for aggregate consideration in an amount equal to $61.4 million, as may be adjusted pursuant to the Stock Purchase Agreement (the “Purchase Price”), including a cash payment after closing of $5.0 million, as adjusted pursuant to Sections 5.6(c), (d), and (f) of the Stock Purchase Agreement (the “Additional Cash Purchase Price”). At closing, we paid to Megatran's selling stockholders $25.0 million in cash on hand, and 1,297,600 restricted shares of our common stock. On September 23, 2024, we paid the Additional Cash Purchase Price to the selling stockholders, which was calculated based on the agreed upon formula set forth in the Stock Purchase Agreement, in the amount of $8.3 million which includes the Additional Cash Purchase Price and the make whole payment. Megatran's wholly-owned subsidiary, NWL, Inc. (together with Megatran, "NWL"), is a U.S.-based global provider of engineered power conversion solutions for demanding industrial and military applications. As a result of this transaction, Megatran became a wholly-owned subsidiary and is operated by our Grid business segment. We refer to this transaction as the "acquisition of NWL".
In June 2025, we completed an offering of 4,743,750 shares of our common stock at a public offering price of $28.00 per share under our Registration Statement on Form S-3. We received aggregate net proceeds of approximately $124.6 million after deducting underwriting discounts and commissions and offering expenses.
Critical Accounting Policies and Estimates
The preparation of the unaudited condensed consolidated financial statements requires that we make estimates and judgments that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base our estimates on historical experience and 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 under different assumptions or conditions.

Our Grid business segment accounted for 85% and 83% of total revenues for both the three and nine months ended December 31, 2025, respectively, compared to 85% and 84% for the three and nine months ended December 31, 2024, respectively. Our Grid business segment revenues increased 21% to $63.2 million in the three months ended December 31, 2025, from $52.3 million in the three months ended December 31, 2024. Our Grid business segment revenues increased 35% to $177.6 million in the nine months ended December 31, 2025, from $131.6 million in the nine months ended December 31, 2024. The increase in the Grid business segment revenues in the three months ended December 31, 2025, compared to the three months ended December 31, 2024, was driven by increased shipments of new energy power systems and additional ship protection systems revenues than in the prior year period along with the addition of Comtrafo revenues. The increase in the Grid business segment revenues in the nine months ended December 31, 2025, compared to the nine months ended December 31, 2024, was driven by the acquisitions of NWL and Comtrafo, increased shipments of new energy power systems, and additional ship protection systems revenues compared to the prior year periods.
Our Wind business segment accounted for 15% and 17% of total revenues for the three and nine months ended December 31, 2025, respectively, compared to 15% and 16% for the three and nine months ended December 31, 2024, respectively. Revenues in the Wind business segment increased 25% to $11.3 million in the three months ended December 31, 2025, from $9.1 million in the three months ended December 31, 2024. Revenues in the Wind business segment increased 43% to $35.1 million in the nine months ended December 31, 2025, from $24.6 million in the nine months ended December 31, 2024. The increase during the three and nine months ended December 31, 2025, compared to the three and nine months ended December 31, 2024, was driven by additional shipments of electrical control systems ("ECS").
Cost of Revenues and Gross Margin
Cost of revenues increased by 15% to $51.7 million for the three months ended December 31, 2025, compared to $45.1 million for the three months ended December 31, 2024. Cost of revenues increased by 29% to $145.0 million for the nine months ended December 31, 2025, compared to $112.0 million for the nine months ended December 31, 2024. Gross margin was 31% and 32% for the three and nine months ended December 31, 2025, respectively, compared to 27% and 28% for the three and nine months ended December 31, 2024, respectively. Cost of revenues includes total amortization expense of $0.1 million in the three and nine months ended December 31, 2025 as a result of Comtrafo acquired backlog intangible assets. In addition, a charge of $0.4 million related to a fair value adjustment for the step-up basis assigned to acquired inventory to properly reflect the fair value in purchase accounting was charged to cost of revenues in the three and nine months ended December 31, 2025, when the inventory was sold. The increase in gross margin in the three and nine months ended December 31, 2025 was due to higher revenues, a favorable product mix and favorable impacts across the business due to pricing increases across product lines.
Operating Expenses
Research and development
Research and development ("R&D") expenses increased 18% in the three months ended December 31, 2025, to $3.5 million from $3.0 million in the three months ended December 31, 2024. R&D expenses increased 46% in the nine months ended December 31, 2025, to $11.6 million from $7.9 million in the nine months ended December 31, 2024. The increase in the three and nine months ended December 31, 2025 was driven primarily by higher overall compensation expense and additional stock-based compensation expense.
Selling, general, and administrative
Selling, general and administrative ("SG&A") expenses increased 33% in the three months ended December 31, 2025, to $15.4 million from $11.6 million in the three ended December 31, 2024. SG&A expenses increased 39% in the nine months ended December 31, 2025, to $43.1 million from $31.0 million in the nine months ended December 31, 2024. The increase in SG&A expense in the three and nine months ended December 31, 2025 was driven primarily by higher overall compensation expense, additional stock-based compensation expense, and acquisition costs related to the acquisition of Comtrafo.
Amortization of acquisition-related intangibles
We recorded amortization expense related to our core technology and know-how and customer relationships of $0.5 million in the three months ended December 31, 2025, and $0.4 million in the three months ended December 31, 2024. We recorded amortization expense related to our core technology and know-how and customer relationships of $1.2 million in the nine months ended December 31, 2025, and $1.3 million in the nine months ended December 31, 2024. The increase in amortization expense in the three months ended December 31, 2025, was a result of additional amortization related to the Comtrafo acquisition, as well as ongoing activity from NEPSI and Neeltran which are using the economic consumption method as the basis to amortize the acquired customer relationships intangible assets. The decrease in amortization expense in the nine months ended December 31, 2025, was a result of additional amortization expense related to the Comtrafo acquisition using the economic consumption method as the basis to amortize the acquired customer relationships intangible assets offset by similar ongoing activity from NEPSI and Neeltran, Inc.
Change in fair value of contingent consideration
The change in fair value of our contingent consideration for the earnout payment on the acquisition of NEPSI resulted in a loss of $3.4 million resulting from an increase in fair value in the nine months ended December 31, 2024. During the three and nine months ended December 31, 2024, we issued 300,000 shares of common stock of the Company to the selling stockholders following certification of the achievement of specified earnout revenue objectives. There was no activity in the three and nine months ended December 31, 2025 as the contingent consideration for NEPSI and NWL was settled during the prior fiscal year. The change in fair value of the Comtrafo contingent consideration was deemed immaterial to the financial statements from the Comtrafo Acquisition Date.

Our Grid business segment generated operating income of $2.0 million and $7.5 million in the three and nine months ended December 31, 2025, respectively, compared to an operating income of $0.2 million and $1.6 million in the three and nine months ended December 31, 2024, respectively. The increase in the Grid business segment operating income in the three and nine months ended December 31, 2025 was due to higher revenues and gross margins.
Our Wind business segment generated operating income of $1.3 million and $4.5 million in the three and nine months ended December 31, 2025, respectively, compared to operating income of $1.1 million and $2.4 million in the three and nine months ended December 31, 2024, respectively. The increase in the Wind business segment operating income in the three and nine months ended December 31, 2025 was due to higher revenues and gross margins from increased sales of ECS units.
Unallocated corporate expenses included a net loss on contingent consideration of $6.7 million in the nine months ended December 31, 2024.
Interest income, net, was $2.0 million and $5.2 million in the three and nine months ended December 31, 2025, respectively, compared to $0.8 million and $2.9 million in the three and nine months ended December 31, 2024, respectively. The increase in interest income, net, in the three and nine months ended December 31, 2025 was due to higher cash balances primarily generated from the public offering completed in June 2025.
Other income (expense), net
Other expense, net, was $0.1 million and both in the three and nine months ended December 31, 2025, compared to other income, net of $0.3 million and other expense, net of $0.2 million in the three and nine months ended December 31, 2024, respectively. The increase in other expense, net, during the three months ended December 31, 2025, compared to the three months ended December 31, 2024 was driven by unfavorable fluctuations in foreign currencies. The decrease in other expense, net, during the nine months ended December 31, 2025, compared to the nine months ended December 31, 2024 was driven by favorable fluctuations in foreign currencies.
Income Taxes
Income tax benefit was $112.3 million and $112.1 million in the three and nine months ended December 31, 2025, respectively, compared to income tax benefit of $0.1 million and $4.9 million in the three and nine months ended December 31, 2024, respectively. The increase in our income tax benefit was primarily due to a $113.1 million non-cash tax benefit from the release of the majority of our valuation allowance against deferred tax assets.
Net income
Net income was $117.8 million and $129.3 million in the three and nine months ended December 31, 2025, respectively, compared to $2.5 million and $4.8 million in the three and nine months ended December 31, 2024, respectively. The increase in net income for the three and nine months ended December 31, 2025 was driven primarily by the release of the valuation allowance and increased revenues and gross margins.
Non-GAAP Financial Measure - Non-GAAP Net Income
Generally, a non-GAAP financial measure is a numerical measure of a company’s performance, financial position or cash flow that either excludes or includes amounts that are not normally excluded or included in the most directly comparable measure calculated and presented in accordance with GAAP. The non-GAAP measures included in this Quarterly Report on Form 10-Q, however, should be considered in addition to, and not as a substitute for or superior to the comparable measures prepared in accordance with GAAP.
We define non-GAAP net income as net income before stock-based compensation, acquisition costs, amortization of acquisition-related intangibles, change in fair value of contingent consideration, and other non-cash or unusual charges. We believe non-GAAP net income assists management and investors in comparing our performance across reporting periods on a consistent basis by excluding these non-cash charges and other items that we do not believe are indicative of our core operating performance. In addition, we use non-GAAP net income as a factor to evaluate the effectiveness of our business strategies. A reconciliation of GAAP to non-GAAP net income is set forth in the table below (in thousands, except per share data):

We generated non-GAAP net income of $123.5 million and $144.0 million, or $2.81 and $3.42 per share, for the three and nine months ended December 31, 2025, respectively, compared to a non-GAAP net income of $6.0 million and $19.3 million, or $0.16 and $0.52 per share, for the three and nine months ended December 31, 2024, respectively. For the three and nine months ended December 31, 2025, the increase in non-GAAP net income was a result of the release of the valuation allowance and higher revenues and gross margins.
Liquidity and Capital Resources
The Company’s primary sources of liquidity are internally generated cash provided by operating activities, our cash and cash equivalents on hand, along with access to capital markets, including through our currently effective Registration Statements on Form S-3. We believe that these sources of liquidity are sufficient to meet both our short-term and reasonably foreseeable long-term requirements and obligations. As of December 31, 2025, we had cash and cash equivalents of $141.1 million.
Our cash requirements depend on numerous factors, including the successful completion of our product development activities, our ability to commercialize our Resilient Electric Grid and ship protection system solutions, the rate of customer and market adoption of our products, collecting receivables according to established terms, the continued availability of U.S. government funding during the product development phase of our superconductor-based products and whether Inox is successful in executing on Solar Energy Corporation of India Limited orders or in obtaining additional orders under the new central and state auction regime. We continue to closely monitor our expenses and, if required, may reduce our operating and capital spending to enhance liquidity.
On June 10, 2025, we completed an offering of 4,125,000 shares of our common stock at a public offering price of $28.00 per share under our Registration Statement on Form S-3. We received net proceeds of approximately $108.2 million after deducting underwriting discounts and commissions and offering expenses. The offering included an option to purchase an additional 618,750 shares over the initial offering of 4,125,000 shares at the public offering price, less underwriting discounts and commission. This option was fully exercised on June 16, 2025 resulting in an additional $16.3 million in net proceeds, after deducting underwriting discounts and commissions and offering expenses payable by the Company, for total net proceeds of approximately $124.6 million. The offering closed on June 16, 2025.
As of December 31, 2025, we had cash, cash equivalents and restricted cash of $147.1 million, compared to $85.4 million as of March 31, 2025, an increase of $61.7 million. As of December 31, 2025, we had $22.8 million in cash, cash equivalents, and restricted cash in foreign bank accounts. Our cash, cash equivalents, and restricted cash are summarized as follows (in thousands):
| December 31, 2025 |
March 31, 2025 |
|||||||
| Cash and cash equivalents |
$ | 141,072 | $ | 79,494 | ||||
| Restricted cash |
6,039 | 4,274 | ||||||
| Total cash, cash equivalents, and restricted cash |
$ | 147,111 | $ | 83,768 | ||||
For the nine months ended December 31, 2025, net cash provided by operating activities was $13.9 million, compared to $22.0 million for the nine months ended December 31, 2024. The decrease in cash flows provided by operating activities in the nine months ended December 31, 2025 was due primarily to changes in deferred revenue, offset by change in accounts payable and accrued expenses, accounts receivable, deferred income taxes, and stock-based compensation expense.
For the nine months ended December 31, 2025, net cash used in investing activities was $75.3 million, compared to $34.1 million for the nine months ended December 31, 2024. The increase in net cash used in investing activities was primarily due to cash paid for the Comtrafo acquisition in the current year.
For the nine months ended December 31, 2025, net cash provided by financing activities was $123.9 million compared to cash used in financing activities of $0.1 million for the nine months ended December 31, 2024. The increase in net cash provided by financing activities was due primarily to the equity raise in June 2025.
As of December 31, 2025, we had $3.3 million of restricted cash included in long-term assets and $2.8 million of restricted cash included in current assets. At March 31, 2025, we had $4.3 million of restricted cash included in long-term assets and $1.6 million of restricted cash in current assets. These amounts included in restricted cash primarily represent collateral deposits to secure surety bonds and letters of credit for various customer contracts. These deposits are held in interest bearing accounts.
We are a party to many contractual obligations involving commitments to make payments to third parties. These obligations impact our short-term and long-term liquidity and capital resource needs. Certain contractual obligations are reflected on the condensed consolidated balance sheet as of December 31, 2025, while others are considered future commitments. We have various contractual arrangements, under which we have committed to purchase certain minimum quantities of goods or services on an annual basis. For information regarding our other contractual obligations, refer to Note 3, "Revenue Recognition," Note 14, "Contingent Consideration," Note 16, "Leases" and Note 17, "Commitments and Contingencies" to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q. Other than the contingent consideration owed to the former Comtrafo stockholders there have been no material changes to our contractual obligations from those disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2025.
We believe we have sufficient available liquidity to fund our operations and capital expenditures for at least the next twelve months and into the future. We raised $124.6 million, net of offering expenses, through an equity raise in June 2025, of which $88.3 million was used for the Comtrafo Acquisition. In addition, we may seek to raise additional capital, which could be in the form of loans, convertible debt or equity, to fund our operating requirements and capital expenditures. There can be no assurance that we will be able to raise additional capital on favorable terms or at all or execute on any other means of improving our liquidity as described above. Additionally, the impact of global sources of instability, including the ongoing war between Russia and Ukraine, tariffs, trade restrictions and resulting trade conflicts, instability of financial institutions and political instability in the United States, on the global financial markets may reduce our ability to raise additional capital, if necessary, which could negatively impact our liquidity.
Legal Proceedings
From time to time, we are involved in legal and administrative proceedings and claims of various types. We record a liability in our condensed consolidated financial statements for these matters when a loss is known or considered probable and the amount can be reasonably estimated. We review these estimates each accounting period as additional information is known and adjust the loss provision when appropriate. If a matter is both probable to result in liability and the amounts of loss can be reasonably estimated, we estimate and disclose the possible loss or range of loss to the extent necessary to make the condensed consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in our condensed consolidated financial statements.
Recent Accounting Pronouncements
In March 2024, the FASB issued ASU 2024-02, Codification Improvements—Amendments to Remove References to the Concepts Statements. The amendments in ASU 2024-02 contain amendments to the Codification that remove references to various FASB Concepts Statements. Following the release of ASU 2024-02 in March 2024, the effective date was annual reporting periods beginning after December 15, 2024. As of December 31, 2025, we are evaluating the impact on our consolidated financial statements.
In November 2024, the FASB issued ASU 2024-03, Income Statement—Reporting Comprehensive Income—Expense Disaggregation Disclosures. The amendments in ASU 2024-03 address investor requests for more disclosure of disaggregated financial reporting information about expenses presented in the income statement. Following the release of ASU 2024-03 in November 2024, the effective date will be annual reporting periods beginning after December 15, 2026. As of December 31, 2025, we are evaluating the impact on our consolidated financial statements.
We do not believe that, outside of those disclosed here, there are any other recently issued accounting pronouncements that will have a material impact on our condensed consolidated financial statements.
| QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK |
We face exposure to financial market risks, including adverse movements in foreign currency exchange rates and changes in interest rates. These exposures may change over time as our business practices evolve and could have a material adverse impact on our financial results.
Cash and cash equivalents
Our exposure to market risk through financial instruments, such as short-term cash instruments with maturities of three months or less, is limited to interest rate risk and is not material. Our investments in marketable securities consist primarily of money market accounts and short-term certificates of deposit and are designed, in order of priority, to preserve principal, provide liquidity, and maximize income. Interest rates are variable and fluctuate with current market conditions. We do not believe that a 10% change in interest rates would have a material impact on our financial position or results of operations.
Foreign currency exchange risk
The functional currency of each of our foreign subsidiaries is the U.S. dollar, except for AMSC Austria (Euro), AMSC Brazil and Comtrafo (Real), for which the local currencies are the functional currency. The assets and liabilities of AMSC Austria, AMSC Brazil and Comtrafo are translated into U.S. dollars at the exchange rate in effect at the balance sheet date and income and expense items are translated at average rates for the period. Cumulative translation adjustments are excluded from net income and shown as a separate component of stockholders’ equity.
We face exposure to movements in foreign currency exchange rates whenever we, or any of our subsidiaries, enter into transactions with third parties that are denominated in currencies other than our functional currency. Intercompany transactions between entities that use different functional currencies also expose us to foreign currency risk. Gross margins of products we manufacture in the U.S and sell in currencies other than the U.S. dollar are also affected by foreign currency exchange rate movements. In addition, a portion of our earnings is generated by our foreign subsidiaries, whose functional currencies are other than the U.S. dollar, and our revenues and earnings could be materially impacted by movements in foreign currency exchange rates upon the translation of the earnings of such subsidiaries into the U.S. dollar. If the functional currency for AMSC Austria, AMSC Brazil, or Comtrafo were to fluctuate by 10% the net effect would be immaterial to our consolidated financial statements.
Foreign currency gains (losses) are included in net income and were no gain or loss and a loss of $0.3 million for the three and nine months ended December 31, 2025, respectively, and a loss of $0.2 million and $0.7 million for the three and nine months ended December 31, 2024, respectively.
| CONTROLS AND PROCEDURES |
Evaluation of Disclosure Controls and Procedures
Our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures as of December 31, 2025. The term “disclosure controls and procedures,” as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act, means controls and other procedures of a company that are designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed by a company in the reports that it files or submits under the Exchange Act is accumulated and communicated to the Company’s management, including its principal executive and principal financial officers, as appropriate to allow timely decisions regarding required disclosure. Management recognizes that any controls and procedures, no matter how well designed and operated, can provide only reasonable assurance of achieving their objectives and management necessarily applies its judgment in evaluating the cost-benefit relationship of possible controls and procedures. Based on the evaluation of our disclosure controls and procedures as of December 31, 2025, our Chief Executive Officer and Chief Financial Officer concluded that, as of such date, our disclosure controls and procedures were effective at the reasonable assurance level.
Changes in Internal Control over Financial Reporting
There were no changes to our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the quarter ended December 31, 2025 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

January 29, 2026
To:
Comtrafo Indústria de Transformadores Elétricos S.A. Irineu Minato, Stockholder Representative
Re: Amendment No. 1 to Stock Exchange Agreement
Dear Irineu:
Reference is made to that certain Stock Exchange Agreement by and among Comtrafo Indústria de Transformadores Elétricos S.A. (the “Company”), Mardin Participações Ltda. (the “Buyer”), the Stockholders, and the other parties named therein (the “Agreement”), pursuant to which the Buyer acquired from the Stockholders, directly or indirectly, all issued and outstanding equity interests of the Target Companies, including the Company. Capitalized terms used but not otherwise defined herein (this “Amendment”) have the meanings given to them in the Agreement.
The Parties acknowledge that the Closing occurred on December 5, 2025, and desire to amend the Agreement as set forth below to reflect their mutual understanding regarding the financial accounting treatment of, and allocation of certain Taxes with respect to, transactions occurring in the Ordinary Course of Business as of or after 12:01am BRT on the Closing Date (collectively, “Closing Date Transactions”).
For the avoidance of doubt, Closing Date Transactions specifically excludes any one or more transactions arising from, related to, or otherwise consummated or effected in connection with or pursuant to the Agreement, including without limitation, (i) any transaction effected or executed respecting or as part of the Pre-Closing Reorganization, (ii) the capitalization and share subscription in the Company by AMSC Brazil under Section 1.5(a)(i) of the Agreement, (iii) the sale, acquisition, lease, transfer or disposition of any Real Property, Intellectual Property, or the Arim Assets, (iv) any transactions which are the subject of or relate to the payment of any Company Expenses, (v) the termination of any Affiliate Transactions, (vi) the retirement, extinguishment, forbearance or payment (whether partial or in full) of any Indebtedness, (vii) payments to, or consideration or compensation received by the Stockholders in connection with the Pre-Closing Reorganization, Closing or any of the transactions arising from, related to, or consummated in connection with, under or pursuant to the Agreement, or (vii) or any other transactions or tax elections made by, between, among or involving, the Stockholders, Stockholder Group Members, or their Affiliates.
|
1. |
Accounting Cut-Off |
Except as expressly provided under the Agreement, and solely for purposes of Buyer preparing the Company’s financial statements, the books and records of the Company shall be treated as closed as of 12:01 a.m. BRT on December 5, 2025, and that the Closing Date Transactions shall be treated as occurring after the Closing solely for such purposes. For the avoidance of doubt, the Parties hereby agree and acknowledge that the Stockholders are not responsible nor have participated or rendered advice regarding the accounting treatment of the Closing Date Transactions or any aspect for preparing any financial statements of the Company covering any periods after the Closing.
|
2. |
Tax Matters |
Notwithstanding Section 5.4(a)(ii) of the Agreement, the Buyer acknowledges and agrees that (i) any sales, value added or similar Taxes which are imposed on the Company or for which the Company is liable in specific respect of any Closing Date Transaction, and (ii) Taxes payable by the Company on the Company’s revenue or income specifically attributable to the Closing Date Transactions (collectively, “Closing Date Transaction Taxes”) shall not constitute Unpaid Income Tax Liabilities and shall be excluded from the Special Reps and Indemnities. For the avoidance of doubt, (i)the allocation of responsibility and liability for all other Taxes (including Taxes attributable to the Pre-Closing Reorganization, any periods prior to Closing, or any taxable periods which commence prior to Closing but conclude thereafter) shall otherwise remain governed exclusively by the terms of the Agreement (including Section 5.4), which remain unchanged; and (ii) any other indemnity provisions under the Agreement not expressly amended hereby remain unchanged and effective pursuant to the Agreement.
|
3. |
No Change to Other Provisions |
For the avoidance of doubt, (i) this Amendment is intended only to address the accounting treatment and tax matters described above, and does not amend or modify the actual time at which the Closing occurred under the Agreement; (ii) nothing in this Amendment changes the time as of which any representation, warranty, or covenant in the Agreement is made or deemed made; and
(iii) except as expressly provided in Section 2 above, any matter to be determined or any calculation to be performed on or measured with respect to any specific date or time shall remain unchanged (including, without limitation, determination of Company Cash, or except as expressly provided under Section 2 above, allocation of responsibility or liability for any Taxes under the Agreement).
|
4. |
Miscellaneous |
This Amendment shall be deemed to form part of, and be incorporated into, the Agreement. From and after the date hereof, any reference to the “Agreement” shall be deemed to be a reference to the Agreement as amended by this Amendment. Except as expressly amended hereby, the Agreement shall remain in full force and effect in accordance with its terms. In the event of any conflict between the terms of this Amendment and the Agreement, the terms of this Amendment
shall control solely with respect to the matters expressly set forth in Sections 1 and 2 above. This Amendment shall be governed by, and construed in accordance with, the laws governing the Agreement. This Amendment may be executed in counterparts (including by electronic or .pdf signature), each of which shall be deemed an original and all of which together shall constitute one and the same instrument.
[Signature Page Follows]
IN WITNESS WHEREOF, the Parties have executed this Amendment as of the date first written above.
