AMERICAN SUPERCONDUCTOR CORPORATION

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

1. Nature of the Business and Operations and Liquidity

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 that 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. 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 financial statements prepared in accordance with GAAP have been condensed or omitted pursuant to those instructions. The year-end condensed 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 September 30, 2022 and 2021 and the financial position at September 30, 2022; 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 consolidated financial statements for the year ended March 31, 2022, and notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2022 filed with the SEC on June 1, 2022.

Liquidity

The Company has historically experienced recurring operating losses and as of September 30, 2022, the Company had an accumulated deficit of $1,039 million. In addition, the Company has historically experienced recurring negative operating cash flows. At September 30, 2022, the Company had cash and cash equivalents of $27.8 million. Cash used in operations for the six months ended September 30, 2022 was $11.6 million.

In February 2021, the Company filed a shelf registration statement on Form S-3 that will expire in February 2024 (the “Form S-3”). The Form S-3 allows the Company to offer and sell from time-to-time up to $250 million of common stock, debt securities, warrants or units comprised of any combination of these securities. The Form S-3 is intended to provide the Company flexibility to conduct registered sales of the Company's securities, subject to market conditions, in order to fund the Company's future capital needs. The terms of any future offering under the Form S-3 will be established at the time of such offering and will be described in a prospectus supplement filed with the SEC prior to the completion of any such offering.

The COVID-19 pandemic continues to rapidly evolve. While the COVID-19 pandemic has not materially disrupted the Company's business to date, any future actions necessitated by the COVID-19 pandemic may result in disruption to the Company's business. In addition, the Company is experiencing substantial inflationary pressure in its supply chain, some delays in sourcing materials needed for its products and some production disruption resulting from higher than typical employee absenteeism, all of which have increased the Company’s cost of revenues and decreased gross margin. The extent to which the pandemic impacts the Company’s business, liquidity, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence. Changes in macroeconomic conditions arising from the COVID-19 pandemic or for other reasons, such as the ongoing war between Russia and Ukraine, inflation, rising interest rates, labor force availability, sourcing, material delays and global supply chain disruptions could have a material adverse effect on the Company’s business, financial condition and results of operation.

The Company believes that based on the information presented above and its quarterly management assessment, it has sufficient liquidity to fund its operations and capital expenditures for the next twelve months following the issuance of the financial statements for the six months ended September 30, 2022. The Company’s liquidity is highly dependent on its ability to increase revenues, its ability to control its operating costs, and its ability to raise additional capital, if necessary. The impact of the COVID-19 pandemic and other sources of instability, including the war between Russia and Ukraine, on the global financing markets may reduce the Company's ability to raise additional capital, if necessary, which could negatively impact the Company's liquidity. There can be no assurance that the Company will be able to continue to raise additional capital, on favorable terms or at all, from other sources or execute on any other means of improving liquidity described above.

2. Acquisitions

2021 Acquisition of Neeltran

On May 6, 2021, the Company entered into a Purchase and Sale Agreement (the "Real Property Purchase Agreement") and a Stock Purchase Agreement (the "Neeltran Stock Purchase Agreement") with the selling equity holders named therein. Also on May 6, 2021, pursuant to the terms of the Real Property Purchase Agreement, the Company's wholly-owned Connecticut limited liability company, AMSC Husky LLC ("AMSC Husky"), purchased the real property that serves as Neeltran's headquarters for $4.3 million, of which (a) $2.4 million was paid in immediately available funds by AMSC Husky to the owners of such real property, and (b) $1.9 million was paid directly to TD Bank as full payment for the outstanding indebtedness secured by the mortgage on such real property.

Pursuant to the terms of the Neeltran Stock Purchase Agreement, the Company purchased all of the issued and outstanding shares of capital stock of Neeltran, Inc., a Connecticut corporation ("Neeltran") and Neeltran International, Inc., a Connecticut corporation ("International") for $1.0 million in cash and 301,556 shares of the Company's common stock, $.01 par value per share ("AMSC Shares"), that were paid and issued, respectively, to the Neeltran selling stockholders. The Company also paid $1.1 million to International selling stockholders to pay off previous loans made by them to Neeltran.

Additionally, the Company paid approximately $7.6 million, including $1.9 million of indebtedness secured by the mortgage on the real property as described above, directly to Neeltran lenders at closing to extinguish outstanding Neeltran indebtedness to third parties. The total purchase price of $16.4 million includes cash paid, the fair value of the AMSC Shares issued at closing and the debt payoff on behalf of the sellers as follows (in millions):

Cash payment |  | $ | 4.4 |
Issuance of 301,556 shares of Company's common stock |  |  | 4.4 |
Debt payment to third party lenders on behalf of sellers |  |  | 7.6 |
Total consideration |  | $ | 16.4 |

The Neeltran Acquisition completed by the Company during the fiscal year ended March 31, 2022 has been accounted for under the purchase method of accounting in accordance with ASC 805, Business Combinations. The Company allocated the purchase price to the assets acquired and liabilities assumed at their estimated fair values as of the date of Neeltran 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. As Neeltran was previously a private company, the adoption of Accounting Standards Codification 842 ("ASC 842") was completed as part of the Neeltran Acquisition. See Note 15, "Leases" for further details. Neeltran had previously adopted Accounting Standards Codification 606, Revenue from Contracts with Customers ("ASC 606") as part of prior year audited financial statements.

The following table summarizes the allocation of the purchase price based on the estimated fair value of the assets acquired and liabilities assumed in connection with the Neeltran Acquisition (in millions):

Cash and short-term investments |  | $ | 0.5 |
Net working capital (excluding inventory and deferred revenue) |  |  | (0.9 | )
Inventory |  |  | 9.0 |
Property, plant and equipment |  |  | 6.5 |
Deferred revenue |  |  | (10.0 | )
Deferred tax liability |  |  | (2.3 | )
Net tangible assets/(liabilities) |  |  | 2.8 |
Backlog |  |  | 0.1 |
Trade names and trademarks |  |  | 1.2 |
Customer relationships |  |  | 3.5 |
Net identifiable intangible assets/(liabilities) |  |  | 4.8 |
Goodwill |  |  | 8.8 |
Total purchase consideration |  | $ | 16.4 |

Inventory include s a $0.6 million adjustment to step up the inventory balance to fair value consistent with the purchase price allocation. The fair value was based on the estimated selling price of the inventory, less the remaining manufacturing and selling cost and a normal profit margin on those manufacturing and selling efforts. The inventory step up adjustment increased cost of revenue by $0.6 million in the twelve month period ended March 31, 2022 as the inventory was sold. This increase is not reflected in the pro forma condensed combined statements of operations because it does not have a continuing impact beyond the first year.

Backlog of $0.1 million was evaluated using the multi period excess earnings method under the income approach. The contracts with customers do not provide for any guarantees to source all future requirements from the Company. The amortization method being utilized is economic consumption estimated over a two year period with the expense being allocated to cost of revenues.

﻿

Customer relationships of $3.5 million relates to customers currently under contract and was determined based on a multi period excess earnings method under the income approach. The method of amortization being utilized is the economic consumption over 7 years with the expense being allocated to SG&A.

Trade names and trademarks of $1.2 million were reviewed using the assumption that the Company would continue to utilize the Neeltran trade name indefinitely. The relief from royalty method was utilized using a 1% royalty rate on revenues with a 24.5% discount rate over 15 years.

9

The goodwill represents the value associated with the acquired workforce and expected synergies related to the business combinations of the two companies. Goodwill resulting from the Neeltran Acquisition was assigned to the Company's Grid business segment. Goodwill recognized in the Neeltran Acquisition is not deductible for tax purposes. The Company has finalized its purchase price allocation for the Neeltran Acquisition, and there were no changes to the net assets and goodwill recorded by the Company as of May 6, 2021.

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 Northeast Power Systems, Inc., a New York corporation ("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. Prior to the NEPSI Acquisition, the Company had purchased $0.4 million of products from NEPSI in fiscal year 2019 for which NEPSI was paid and had recorded revenue.

Pursuant to the NEPSI Stock Purchase Agreement, the Company acquired all of the issued and outstanding shares of NEPSI, and membership interest in the realty entity, for which the Company paid $26.0 million in cash and issued 873,657 restricted shares of the Company’s common stock. Additionally, the Company may issue to the selling stockholders up to an additional 1,000,000 shares of common stock upon NEPSI’s achievement of specified revenue objectives during varying periods of up to four years following closing of the NEPSI Acquisition. This contingent consideration is recorded as a derivative liability based on a Monte Carlo simulation to determine fair value at the time of issuance. NEPSI is now a wholly-owned subsidiary of the Company and is operated and reported as a component of its Grid business unit.

The NEPSI Acquisition completed by the Company during the fiscal year ended March 31, 2021 has been accounted for under the purchase method of accounting in accordance with ASC 805, Business Combinations. The Company allocated the purchase price to the assets acquired and liabilities assumed at their estimated fair values as of the date of NEPSI 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. As NEPSI was previously a private company, the adoption of ASC 606 was completed as part of the NEPSI Acquisition. See Note 3, "Revenue Recognition" for further details. There were no leases acquired and the NEPSI Acquisition had no impact to the Company's reporting under ASC 842.

The total purchase price of approximately $42.4 million includes the fair value of shares of the Company’s common stock issued at closing, cash paid, and contingent consideration as follows (in millions):

Cash payment |  | $ | 26.0 |
Issuance of 873,657 shares of Company’s common stock |  |  | 12.4 |
Contingent consideration |  |  | 4.0 |
Total consideration |  | $ | 42.4 |

Total consideration consists of (a) cash of $26.0 million, (b) issuance of the Company's common stock, using $14.23 per share, which was the closing price on the day that the Company acquired NEPSI, and (c) $4.0 million of contingent consideration for the earnout liability valued as of the NEPSI Acquisition Date. NEPSI Acquisition costs of $0.3 million were recorded in selling, general and administrative ("SG&A") costs for the fiscal year ended March 31, 2021.

The fair value of the contingent consideration was determined using a Monte Carlo model and is accounted for as a derivative liability which is revalued at the fair value determined at each subsequent balance sheet date until the contingencies are resolved and the shares to be issued are determined, with the change in fair value recorded in the current period operating loss or (income). See Note 13, "Contingent Consideration" for further details and a summary of key assumptions used to determine fair value in each period.

The following table summarizes the allocation of the purchase price based on the estimated fair values of the assets acquired and liabilities assumed and related deferred income taxes in connection with the NEPSI Acquisition (in millions):

Net working capital (excluding inventory and deferred revenue) |  | $ | 0.1 |
Inventory |  |  | 4.2 |
Property, plant and equipment |  |  | 2.3 |
Deferred revenue |  |  | (2.7 | )
Deferred tax liability |  |  | (1.7 | )
Net tangible assets/(liabilities) |  |  | 2.2 |
Backlog |  |  | 0.6 |
Trade names and trademarks |  |  | 0.6 |
Customer relationships |  |  | 6.1 |
Net identifiable intangible assets/(liabilities) |  |  | 7.3 |
Goodwill |  |  | 32.9 |
Total purchase consideration |  | $ | 42.4 |

Inventory includes a $1.0 million adjustment to step up the inventory balance to fair value consistent with the purchase price allocation. The fair value was determined based on the estimated selling price of the inventory, less the remaining manufacturing and selling cost and a normal profit margin on those manufacturing and selling efforts. The $1.0 million step up adjustment increased cost of revenue in the fiscal year ended March 31, 2021 as the inventory was sold. This increase is not reflected in the pro forma condensed combined statements of operations because it does not have a continuing impact beyond the first year.

Backlog of $0.6 million was evaluated using the multi period excess earnings method under the income approach. The contracts with customers do not provide for any guarantees to source all future requirements from the Company. The amortization method being utilized is economic consumption estimated over a two year period with the expense being allocated to cost of revenues.

Customer relationships of $6.1 million relates to customers currently under contract and was determined based on a multi period excess earnings method under the income approach. The method of amortization being utilized is the economic consumption over 7 years with the expense being allocated to SG&A.

Trade names and trademarks of $0.6 million were reviewed, using the assumption that the Company would continue to utilize the NEPSI trade name indefinitely. The relief from royalty method was utilized using an 8% royalty rate on revenues with a 13% discount rate over 8 years.

Goodwill represents the value associated with the acquired workforce and expected synergies related to the business combination of the two companies. Goodwill resulting from the NEPSI Acquisition was assigned to the Company’s Grid business segment. Goodwill recognized in the NEPSI Acquisition is not deductible for tax purposes. The $1.7 million of deferred tax liability is primarily related to inventory step up and intangibles.

3. Revenue Recognition

The Company’s revenues in its Grid business 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 business 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 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. In the three and six months ended September 30, 2022, 83% and 77% of revenue, respectively, was recognized at the point in time when control transferred to the customer, with the remainder being recognized over time. In the three and six months ended September 30, 2021, 86% and 82% of revenue, respectively, was recognized at the point in time when control transferred to the customer, with the remainder being recognized over time.

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.

The Company's equipment and system product line includes certain contracts which do not meet the requirements of an exchange transaction and therefore do not fall within the scope of ASC 606. As these non-exchange transaction contracts are considered grant revenue and do not fall within any specific accounting literature, the Company follows guidance within ASC 606 by analogy to recognize grant revenue over time. The Company recorded no grant revenue in each of the three and six months ended September 30, 2022. In the three and six months ended September 30, 2021, the Company recorded $0.3 million and $0.8 million in grant revenue, respectively, which is included in the Company’s Grid business segment revenue.

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 represent 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 a reasonable profit margin cannot be assured throughout the entire contract, 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 reassessed 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 one to three years, and extended service-type warranties at the customer's option for an additional term ranging up to four 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.

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; in such cases the long-term amount will be assessed for materiality. 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’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 30 to 60 days from delivery.

As of September 30, 2022, and 2021, the Company’s contract assets and liabilities primarily relate to the timing differences between cash received from a customer in connection with contractual rights to invoicing and the timing of revenue recognition following completion of performance obligations. The Company's accounts receivable balance is made up entirely of customer contract related balances. Changes in the Company’s contract assets, which are included in “Unbilled accounts receivable” and “Deferred program costs” (see Note 8, “Accounts Receivable” and Note 9, “Inventory” for a reconciliation to the condensed consolidated balance sheets) and "Contract liabilities", which are included in the current portion and long-term portion of "Deferred revenue" in the Company’s condensed consolidated balance sheets, are as follows (in thousands):

The Company’s remaining performance obligations represent the unrecognized revenue value of the Company’s contractual commitments. The Company’s performance obligations may vary significantly each reporting period based on the timing of major new contractual commitments. As of September 30, 2022, the Company had outstanding performance obligations on existing contracts under ASC 606 to be recognized in the next twelve months of approximately $101.0 million. There are also approximately $18.1 million of outstanding performance obligations to be recognized over a period of thirteen to sixty months. The remaining performance obligations are subject to customer actions and therefore the timing of revenue recognition cannot be reasonably estimated. The twelve-month performance obligations include anticipated shipments to Inox based on the twelve-month rolling forecast provided by Inox on the multi-year supply contract. The quantities specified in any forecast provided by Inox related to the multi-year supply contract are firm and irrevocable for the first three months of a twelve-month rolling forecast. The timing of the performance obligations beyond the twelve-month forecast provided by Inox are not determinable and therefore are not included in the total remaining performance obligations.

The following table sets forth customers who represented 10% or more of the Company’s total revenues for the three and six months ended September 30, 2022 and 2021:

|  |  | Three Months Ended |  |  | Six Months Ended |

4. Stock-Based Compensation

The Company accounts for its stock-based compensation at fair value. The following table summarizes stock-based compensation expense by financial statement line item for the three and six months ended September 30, 2022 and 2021 (in thousands):

|  | Three Months Ended September 30, |  |  | Six Months Ended September 30, |

Total |  | $ | 1,019 |  |  | $ | 1,101 |  |  | $ | 2,052 |  |  | $ | 2,393 |

The Company issued 338,500 shares of restricted stock awards during the three and six months ended September 30, 2022, and 25,806 shares of immediately vested common stock during the six months ended September 30, 2022. The Company issued 47,604 shares of immediately vested common stock, all of which were issued in lieu of cash bonuses, during the three months ended September 30, 2021, and 166,648 shares of immediately vested common stock, of which 158,356 shares were issued in-lieu of cash bonuses, and 309,700 shares of restricted stock awards during the six months ended September 30, 2021. These restricted stock awards generally vest over 2-3 years. Awards for restricted stock include both time-based and performance-based awards. For options and restricted stock awards that vest upon the passage of time, expense is being recorded over the vesting period. Performance-based awards are expensed over the requisite service period based on probability of achievement.

The estimated fair value of the Company’s stock-based awards, less expected annual forfeitures, is amortized over the awards’ service period. The total unrecognized compensation cost for unvested stock options was less than $0.1 million during the six months ended September 30, 2022. This expense will be recognized over a weighted average of approximately 1.7 years. The total unrecognized compensation cost for unvested outstanding restricted stock was $5.2 million at September 30, 2022. This expense will be recognized over a weighted-average expense period of approximately 1.6 years.

The Company granted 20,564 stock options during the six months ended September 30, 2022. The Company did not grant any stock options during the three months ended September 30, 2022 or the three and six months ended September 30, 2021. The stock options granted during the six months ended September 30, 2022 will vest over 2 years. The weighted average assumptions used in the Black Scholes valuation model for stock options granted during the six months ended September 30, 2022 are as follows:

|  | Three Months Ended September 30, |  |  | Six Months Ended September 30, |
|  | 2022 |  |  | 2021 |  |  | 2022 |  |  | 2021 |
Expected volatility |  |  | N/A |  |  |  | N/A |  |  |  | 71.40 | % |  |  | N/A |
Risk-free interest rate |  |  | N/A |  |  |  | N/A |  |  |  | 3.10 | % |  |  | N/A |
Expected life (years) |  |  | N/A |  |  |  | N/A |  |  |  | 6.14 |  |  |  | N/A |
Dividend yield |  |  | N/A |  |  |  | N/A |  |  |  | None |  |  |  | N/A |

5. Computation of Net Loss per Common Share

Basic net loss per share (“EPS”) is computed by dividing net loss by the weighted-average number of common shares outstanding for the period. Where applicable, diluted EPS is computed by dividing the net loss 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 each of the three and six months ended September 30, 2022, and 2021, 1.1 million shares were not included in the calculation of diluted EPS. Of these, 1.0 million relate to shares tied to the derivative liability for which the contingency has not yet been met, and 0.1 million relate to outstanding stock options as they were considered anti-dilutive.

The following table reconciles the numerators and denominators of the earnings per share calculation for the three and six months ended September 30, 2022 and 2021 (in thousands, except per share data):

|  | Three Months Ended September 30, |  |  | Six Months Ended September 30, |

6. Goodwill and Other Intangibles

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. The Company's goodwill balance relates to the Neeltran Acquisition in fiscal 2021, the 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 not amortized but reviewed for impairment. Goodwill is reviewed annually and whenever events or changes in circumstances indicate that the carrying value of the goodwill might not be recoverable.

The following table provides a roll forward of the changes in the Company's Grid business segment goodwill balance:

|  | Goodwill |
March 31, 2021 |  | $ | 34,634 |
Neeltran Acquisition |  |  | 8,837 |
March 31, 2022 |  | $ | 43,471 |
Less impairment loss |  |  | - |
September 30, 2022 |  | $ | 43,471 |

The Company did not identify any triggering events in the three and six months ended September 30, 2022 that would require interim impairment testing of goodwill.

Other Intangibles

Intangible assets at September 30, 2022 and March 31, 2022 consisted of the following (in thousands):

|  | September 30, 2022 |  |  | March 31, 2022 |  |  |  |  |

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 six months ended September 30, 2022.

15

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, are measured using such inputs as quoted prices and are classified within Level 1 of the valuation hierarchy. Cash equivalents consist principally of certificates of deposits and money market accounts.

Marketable Securities

Marketable securities consist of certificates of deposit that are measured using such inputs as quoted prices and are classified within Level 1 of the valuation hierarchy. The Company determines the appropriate classification of its marketable securities at the time of purchase and re-evaluates such classification as of each balance sheet date. All marketable securities are considered available for sale and are carried at fair value. Changes in fair value are recorded to other income (expense), net. The Company had no outstanding marketable securities as of September 30, 2022 and the Company recognized no change in the three and six months ended September 30, 2022. The Company recognized $0.1 million in unrealized losses on marketable securities, which is recorded in other income (expense), net, for the three and six months ended September 30, 2021. The Company periodically reviews the realizability of each short and long term marketable security when impairment indicators exist with respect to the security. If other than temporary impairment of value of the security exists, the carrying value of the security is written down to its estimated fair value.

Contingent Consideration

Contingent consideration relates to the earnout payment set forth in the NEPSI Stock Purchase Agreement that provides that the selling stockholders may receive up to an additional 1,000,000 shares of common stock of the Company upon the achievement of certain specified revenue objectives over varying periods of up to four years following the NEPSI Acquisition Date. See Note 13, "Contingent Consideration" and Note 2, “Acquisitions” for further discussion. The Company relied on a Monte Carlo method to determine the fair value of the contingent consideration on the NEPSI Acquisition Date and will continue 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 shares to be issued are determined, with the change in fair value recorded in the current period operating loss.

The following table provides the assets and liabilities carried at fair value on a recurring basis, measured as of September 30, 2022 and March 31, 2022 (in thousands):

12. Income Taxes

The Company recorded an income tax benefit of less than $0.1 million and an income tax expense of less than $0.1 million in the three and six months ended September 30, 2022, respectively. The Company recorded an income tax expense of $0.2 million and income tax benefit of $1.9 million in the three and six months ended September 30, 2021, respectively

As a result of a difference in book and tax basis related to the intangible assets acquired in the Neeltran Acquisition (see Note 2, "Acquisitions"), the Company recorded a deferred tax liability of $2.3 million during the six months ended September 30, 2021. As a result, the Company was able to benefit from additional deferred tax assets and therefore released a corresponding valuation allowance of $2.3 million during the six months ended September 30, 2021. Goodwill recognized in the Neeltran Acquisition is not deductible for tax purposes.

18

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 not identify any uncertain tax positions in the six months ended September 30, 2022 and did not have any gross unrecognized tax benefits as of September 30, 2022.

13. Contingent Consideration

Contingent Consideration

The Company evaluated the NEPSI Acquisition earnout payment set forth in the NEPSI Stock Purchase Agreement (see Note 2, "Acquisitions" for further details), which may 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 each period, the fair value of the contingent consideration will be remeasured and the resulting gain or loss will be recognized in operating expenses until the share amount is fixed.

Following is a summary of the key assumptions used in a Monte Carlo simulation to calculate the fair value of the contingent consideration related to the NEPSI Acquisition:

|  | September 30, |  |  | June 30, |  |  |  |  |  |  |  |  |  |  |  |  |
Fiscal Year 2022 |  | 2022 |  |  | 2022 |  |  |  |  |  |  |  |  |  |  |  |  |

Fair value (millions) |  | $ | 1.1 |  |  | $ | 1.4 |  |  |  |  |  |  |  |  |  |  |  |  |
|  | March 31, |  |  | December 31, |  |  | September 30, |  |  | June 30, |  |  | March 31, |
Fiscal Year 2021 |  | 2022 |  |  | 2021 |  |  | 2021 |  |  | 2021 |  |  | 2021 |
Revenue risk premium |  |  | 6.50 | % |  |  | 6.60 | % |  |  | 6.60 | % |  |  | 6.60 | % |  |  | 6.70 | %
Revenue volatility |  |  | 33 | % |  |  | 33 | % |  |  | 30 | % |  |  | 30 | % |  |  | 30 | %
Stock Price |  | $ | 7.61 |  |  | $ | 10.88 |  |  | $ | 14.58 |  |  | $ | 17.39 |  |  | $ | 18.96 |
Payment delay (days) |  |  | 80 |  |  |  | 80 |  |  |  | 80 |  |  |  | 80 |  |  |  | 80 |
Fair value (millions) |  | $ | 1.2 |  |  | $ | 2.6 |  |  | $ | 4.7 |  |  | $ | 7.2 |  |  | $ | 7.1 |

The Company recorded a net gain of $0.3 and $0.1 million resulting from the decrease in the fair value of the contingent consideration in the three and six months ended September 30, 2022. The Company recorded a net gain of $2.4 million and $2.3 million resulting from the decrease in the fair value of the contingent consideration in the three and six months ended September 30, 2021, respectively.

14. Debt

As part of the Neeltran Acquisition, the Company identified four equipment financing agreements that Neeltran had entered into prior to the acquisition on May 6, 2021. The Company determined to account for these agreements as a debt transaction and recorded current and long-term debt liabilities of $0.1 million each during the three months ended June 30, 2021. The current and long-term debt balance is $0.1 million each as of September 30, 2022.

15. Leases

The Company determines whether a contract is or contains a lease at inception of a contract. The Company defines a lease as a contract, or part of a contract, that conveys the right to control the use of identified property or equipment (an identified asset) for a period of time in exchange for consideration. Control over the use of the identified asset means that the Company has both the right to obtain substantially all of the economic benefits from the use of the asset and the right to direct the use of the asset.

The discount rate was calculated using an incremental borrowing rate based on an assessment prepared by the Company through the use of Company credit ratings, consideration of its lease populations potential risk to its total capital structure, and a market rate for a collateralized loan for its risk profile, calculated by a third party. The Company elected to apply the discount rate using the remaining lease term at the date of adoption for Neeltran lease contracts.

Following the Neeltran Acquisition, the Company evaluated all open Neeltran contracts at the date of the acquisition to determine if any applied under ASC 842 as Neeltran, a private company, had deferred adopting ASC 842 prior to the Neeltran Acquisition, as permitted. The Company identified nine lease contracts with terms greater than twelve months and evaluated them under ASC 842 guidance. As part of the implementation, the Company identified one lease contract that classified as a financing lease. The Company does not expect a material impact to the financial statements on an ongoing basis resulting from the adoption of the ASC 842 standard for the Neeltran business and Neeltran will follow the existing policies below.

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 five 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 balance sheet.

19

Finance﻿ Leases

As part of the adoption of ASC 842 at Neeltran, the Company identified one lease contract that is classified as a finance lease. In February 2020, Neeltran entered into a contract to lease a copy machine for an initial term of 39 months, or through May 2023. The Company concluded that the lease should be classified and accounted for as a finance lease as the total value of the lease payments are greater than fair value of the asset. Accordingly, on May 6, 2021, the Company recognized a finance lease right-of-use asset and a finance lease liability of $13.2 thousand on the Neeltran opening balance sheet. As of September 30, 2022, the right-of-use asset related to the finance lease was $4.2 thousand, net of accumulated amortization of $9.0 thousand, and is included in the property and equipment, net on the Company's consolidated balance sheet.

Finance lease right-of-use assets and lease liabilities are recognized similar to an operating lease, at the lease commencement date or the date the lessor makes the leased asset available for use. Finance lease right-of-use assets are generally amortized on a straight-line basis over the lease term, and the carrying amount of the finance lease liabilities are (1) accreted to reflect interest using the incremental borrowing rate if the rate implicit in the lease is not readily determinable, and (2) reduced to reflect lease payments made during the period. Amortization expense for finance lease right-of-use assets and interest accretion on finance lease liabilities are recorded to depreciation expense and interest expense, respectively in the Company's consolidated statement of operations.

16. 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 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 consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in its consolidated financial statements.

Other

The Company enters into long-term construction contracts with customers that require the Company to obtain performance bonds. The Company is required to deposit an amount equivalent to some or all the face amount of the performance bonds into an escrow account until the termination of the bond. When the performance conditions are met, amounts deposited as collateral for the performance bonds are returned to the Company. In addition, the Company has various contractual arrangements in which minimum quantities of goods or services have been committed to be purchased on an annual basis.

As of September 30, 2022, the Company had $6.0 million of restricted cash included in long-term assets and $3.6 million of restricted cash included in current assets. As of March 31, 2022, the Company had $6.1 million of restricted cash included in long term assets and $2.8 million of restricted cash included in current assets. These amounts included in restricted cash primarily represent deposits to secure letters of credit for various supply contracts and long-term projects, including the irrevocable letter of credit in the amount of $5.0 million to secure certain of the Company's obligations under a subcontract agreement with ComEd. These deposits are held in interest bearing accounts.

17. Business Segments

The Company reports its financial results in two reportable business segments: Grid and Wind.

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 power with exceptional efficiency, reliability, security and affordability 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 wind turbines with exceptional power output, reliability and affordability. The Company provides 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 drivetrains 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.

The operating results for the two business segments are as follows (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 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 loss.

Unallocated corporate expenses consist of a gain on contingent consideration of $0.3 million and $0.1 million in the three and six months ended September 30, 2022. Unallocated corporate expenses consist of a gain on contingent consideration of $2.4 million and $2.3 million in the three and six months ended September 30, 2021. Additionally, unallocated corporate expenses consist of stock-based compensation expense of $1.0 million and $1.1 million in the three months ended September 30, 2022, and 2021, respectively and $2.1 million and $2.4 million in the six months ended September 30, 2022 and 2021, respectively.

Total assets for the two business segments as of September 30, 2022, and March 31, 2022, are as follows (in thousands):

|  | September 30, 2022 |  |  | March 31, 2022 |
Grid |  | $ | 121,227 |  |  | $ | 114,053 |
Wind |  |  | 9,716 |  |  |  | 9,866 |

Executive Overview

We are a leading system provider of megawatt-scale resiliency solutions that orchestrate the rhythm and harmony of power on the grid™, and that protect and expand the capability of the U.S. Navy's fleet. 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 on-board power systems to support fleet electrification, and the need 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 broad and deep intellectual property portfolio consisting of hundreds of patents and licenses worldwide.

We operate our business under two market-facing business units: Grid and Wind. We believe this market-centric structure enables us to more effectively anticipate and meet the needs of the U.S. Navy, electric utilities, industrial facilities, power generation project developers and wind turbine manufacturers.

| • | Grid. Through our Gridtec™ Solutions, our Grid business segment enables electric utilities, industrial facilities, and renewable energy project developers to connect, transmit and distribute power with exceptional efficiency, reliability, security and affordability. We provide transmission planning services that allow us to identify power grid congestion, poor power quality, and other risks, which help us determine how our solutions can improve network performance. These services often lead to sales of our grid interconnection solutions for wind farms and solar power plants, power quality systems and transmission and distribution cable systems. We also sell ship protection products to the U.S. Navy through our Grid business segment.

| • | Wind. Through our Windtec™ Solutions, our Wind business segment enables manufacturers to field wind turbines with exceptional power output, reliability and affordability. We supply advanced power electronics and control systems, license our highly engineered wind turbine designs, and provide extensive customer support services to wind turbine manufacturers. Our design portfolio includes a broad range of drivetrains and power ratings of 2 MW and higher. We provide a broad range of power electronics and software-based control systems that are highly integrated and designed for optimized performance, efficiency, and grid compatibility.

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 2022 refers to the fiscal year that began on April 1, 2022. Other fiscal years follow similarly.

On October 31, 2018, we entered into a Subcontract Agreement with Commonwealth Edison Company (“ComEd”) (the “Subcontract Agreement”) for the manufacture and installation of the Company’s resilient electric grid ("REG") system within ComEd’s electric grid in Chicago, Illinois (the “Project”). As provided in the Subcontract Agreement, the Subcontract Agreement became effective upon the signing of an amendment by us and the U.S. Department of Homeland Security (“DHS”) to the existing contract (the “Prime Contract”) between us and DHS on June 20, 2019. Unless terminated earlier by us, ComEd or DHS according to the terms of the Subcontract Agreement, the term of the Subcontract Agreement will continue until we complete our warranty obligations under the Subcontract Agreement. Under the terms of the Subcontract Agreement, we agreed, among other things, to provide the REG system and to supervise ComEd’s installation of the REG system in Chicago. As part of our separate cost sharing arrangement with DHS under the Prime Contract, we received funding provided by DHS in connection with the Subcontract Agreement of approximately $10.0 million, which represents the total amount of revenue we recognized over the term of the Subcontract Agreement and includes $1.0 million that we have agreed to reimburse ComEd for costs incurred by ComEd while undertaking its tasks under the Subcontract Agreement (the “Reimbursement Amount”). In addition, we are required to deliver an irrevocable letter of credit in the amount of $5.0 million to secure certain Company obligations under the Subcontract Agreement, which we have done, and deposited $5.0 million in an escrow account as collateral to secure such letter of credit. ComEd has agreed to provide the site and provide all civil engineering work required to support the operation and integration of the REG system into ComEd’s electric grid. Other than the Reimbursement Amount, ComEd is responsible for its own costs and expenses. DHS’s approval to commence with construction was obtained on June 20, 2019. Substation work on the project began in late 2019 and we successfully integrated the REG system on Com Ed's electric power grid and the REG system became fully operational in August 2021.

The COVID-19 pandemic continues to rapidly evolve. We are experiencing substantial inflationary pressure in our supply chain, some delays in sourcing materials needed for our products and some production disruption resulting from higher than typical employee absenteeism which have increased our cost of revenues and decreased gross margin. The extent to which the pandemic impacts our business, liquidity, results of operations and financial condition will depend on future developments, which are highly uncertain and cannot be predicted with confidence. Changes in macroeconomic and market conditions arising from the COVID-19 pandemic, or for other reasons, such as the ongoing war between Russia and Ukraine, inflation, rising interest rates, 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 operation.

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. There were no significant changes in the critical accounting policies that were disclosed in our Annual Report on Form 10-K for the fiscal year ended March 31, 2022.

Results of Operations

Three and six months ended September 30, 2022, compared to the three and six months ended September 30, 2021

Revenues

Total revenues decreased 1% to $27.7 million for the three months ended September 30, 2022 and total revenues decreased 6% to $50.4 million for the six months ended September 30, 2022, compared to $27.9 million and $53.3 million for the three and six months ended September 30, 2021, respectively. Our revenues are summarized as follows (in thousands):

|  | Three Months Ended September 30, |  |  | Six Months Ended September 30, |
|  | 2022 |  |  | 2021 |  |  | 2022 |  |  | 2021 |
Revenues: |  |  |  |  |  |  |  |  |  |  |  |  |  |  |  |
Grid |  | $ | 25,698 |  |  | $ | 24,619 |  |  | $ | 45,527 |  |  | $ | 48,119 |
Wind |  |  | 1,982 |  |  |  | 3,289 |  |  |  | 4,833 |  |  |  | 5,209 |
Total |  | $ | 27,680 |  |  | $ | 27,908 |  |  | $ | 50,360 |  |  | $ | 53,328 |

Our Grid business unit accounted for 93% and 90% of total revenues for the three and six months ended September 30, 2022, respectively, compared to 88% and 90% for the three and six months ended September 30, 2021, respectively. Our Grid business unit revenues increased 4% to $25.7 million in the three months ended September 30, 2022, from $24.6 million in the three months ended September 30, 2021. Our Grid business unit revenues decreased 5% to $45.5 million in the six months ended September 30, 2022, from $48.1 million in the six months ended September 30, 2021. The increase in the Grid business unit revenue in the three months ended September 30, 2022, was primarily driven by higher NEPSI revenues than in the prior year period. The decrease in the Grid business unit revenue in the six months ended September 30, 2022, was primarily driven by lower D-VAR revenues than in the prior year period.

Our Wind business unit accounted for 7% and 10% of total revenues for the three and six months ended September 30, 2022, respectively, compared to 12% and 10% for the three and six months ended September 30, 2021, respectively. Revenues in the Wind business unit decreased 40% and 7% to $2.0 million and $4.8 million in the three and six months ended September 30, 2022, from $3.3 million and $5.2 million in the three and six months ended September 30, 2021, respectively. The decrease in the three months ended September 30, 2022, was driven by fewer royalty collections and shipments of electrical control systems ("ECS") to Inox in the three months ended September 30, 2022. The decrease in the six months ended September 30, 2022 was driven by lower license and development revenue as well as fewer royalty collections than in the prior year period.

Cost of Revenues and Gross Margin

Cost of revenues increased by 4% to $25.7 million for the three months ended September 30, 2022, compared to $24.6 for the three months ended September 30, 2021. Cost of revenues decreased by 1% to $46.2 million for the six months ended September 30, 2022, compared to $46.7 million for the six months ended September 30, 2021. Gross margin was 7% and 8% for the three and six months ended September 30, 2022, respectively compared to 12% and 13% for the three and six months ended September 30, 2021. The decrease in gross margin in the three and six months ended September 30, 2022, was due to lower revenues, an unfavorable product mix and inflation pressure in our supply chain.

25

Operating Expenses

Research and development

Research and development ("R&D") expense decreased 13% in each of the three and six months ended September 30, 2022, to $2.3 million from $2.7 million in the three months ended September 30, 2021, and to $5.0 million from $5.7 million in the six months ended September 30, 2021. The decrease in R&D expense was due to an increase in cost share revenues and a higher utilization of our research engineers supporting funded projects.

Selling, general, and administrative

Selling, general and administrative ("SG&A") expenses increased 10% in the three months ended September 30, 2022, to $7.3 million from $6.7 million in the three months ended September 30, 2021. The increase in SG&A expense in the three months ended September 30, 2022, was due to higher overall compensation expense than in the prior year period. SG&A expenses increased 8% to $14.9 million in the six months ended September 30, 2022, compared to $13.8 million in the six months ended September 30, 2021. The increase in SG&A expense in the six months ended September 30, 2022, was due to higher overall compensation expense than in the prior year period.

Amortization of acquisition related intangibles

We recorded amortization expense related to our core technology and know-how, customer relationships, and other intangible assets of $0.7 million and $1.4 million in the three and six months ended September 30, 2022, respectively, and $0.6 million and $1.2 million in the three and six months ended September 30, 2021, respectively. The increase in amortization expense is a result of additional expense tied to the acquisition of Neeltran.

Change in fair value of contingent consideration

The change in fair value of our contingent consideration for the earnout payment on the NEPSI Acquisition resulted in a gain of $0.3 million and $0.1 million in the three and six months ended September 30, 2022, respectively, compared to a gain of $2.4 million and $2.3 million in the three and six months ended September 30, 2021, respectively. The change in the fair value was primarily driven by a decreased likelihood of achieving certain revenue targets and a decline in the Company's stock price.

Operating loss

Our operating loss is summarized as follows (in thousands):

|  | Three Months Ended September 30, |  |  | Six Months Ended September 30, |
|  | 2022 |  |  | 2021 |  |  | 2022 |  |  | 2021 |

Interest income, net, was less than $0.1 million in both the three and six months ended September 30, 2022 and September 30, 2021, respectively.

China dissolution

China dissolution, was $1.9 million in each of the three and six months ended September 30, 2022, respectively, compared to no activity in each of the three and six months ended September 30, 2021 . The increase in China dissolution during the three and six months ended September 30, 2022, was driven by the liquidation of our China entity, resulting in a foreign currency gain/loss from the cumulative translation release of $1.9 million in the three and six months ended September 30, 2022 in which there was no similar transaction in the three and six months ended September 30, 2021.

Other income (expense), net

Other income, net, was $0.1 million and $0.2 million in the three and six months ended September 30, 2022, respectively, compared to other income, net, of less than $0.1 million in the three months ended September 30, 2021 and other expense, net of less than $0.1 million in the six months ended September 30, 2021. The decrease in other expense during the three and six months ended September 30, 2022, was driven by the impacts of favorable fluctuations in foreign currencies during the respective period.

Income Taxes

Income tax benefit was less than $0.1 million in the three months ended September 30, 2022 and income tax expense was less than $0.1 million in the six months ended September 30, 2022. Income tax expense was $0.2 million in the three months ended September 30, 2021 and income tax benefit was $1.9 million in the six months ended September 30, 2021. The increase in income tax benefit in the three months ended September 30, 2022 compared to the same period in fiscal 2021 was primarily due to lower withholding taxes from foreign jurisdictions in the three months ended September 30, 2022. The increase in income tax expense in the six months ended September 30, 2022 compared to the same period in fiscal 2021 was a result of the release of the valuation allowance to offset the recording of the deferred tax liability from the Neeltran Acquisition in the six months ended September 30, 2021.

Net loss

Net loss was $9.9 million and $18.6 million in the three and six months ended September 30, 2022, compared to $4.4 million and $9.8 million in the three and six months ended September 30, 2021. The increase in net loss was driven primarily by the increased operating loss due to lower revenues and gross margins.

Non-GAAP Financial Measure - Non-GAAP Net Loss

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 loss as net loss before China dissolution, stock-based compensation, amortization of acquisition-related intangibles, acquisition costs, change in fair value of contingent consideration, and other non-cash or unusual charges. We believe non-GAAP net loss 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 loss as a factor to evaluate the effectiveness of our business strategies. A reconciliation of GAAP to non-GAAP net loss is set forth in the table below (in thousands, except per share data):

|  | Three Months Ended September 30, |  |  | Six Months Ended September 30, |
|  | 2022 |  |  | 2021 |  |  | 2022 |  |  | 2021 |
Net loss |  | $ | (9,881 | ) |  | $ | (4,434 | ) |  | $ | (18,590 | ) |  | $ | (9,837 | )
China dissolution |  |  | 1,921 |  |  |  | — |  |  |  | 1,921 |  |  |  | — |
Stock-based compensation |  |  | 1,019 |  |  |  | 1,100 |  |  |  | 2,052 |  |  |  | 2,393 |
Amortization of acquisition-related intangibles |  |  | 688 |  |  |  | 668 |  |  |  | 1,400 |  |  |  | 1,289 |
Acquisition costs |  |  | — |  |  |  | (7 | ) |  |  | — |  |  |  | (2,330 | )
Change in fair value of contingent consideration |  |  | (290 | ) |  |  | (2,430 | ) |  |  | (120 | ) |  |  | 681 |
Non-GAAP net loss |  | $ | (6,542 | ) |  | $ | (5,103 | ) |  | $ | (13,337 | ) |  | $ | (7,804 | )
Non-GAAP net loss per share - basic |  | $ | (0.23 | ) |  | $ | (0.19 | ) |  | $ | (0.48 | ) |  | $ | (0.29 | )
Weighted average shares outstanding - basic |  |  | 27,867 |  |  |  | 27,252 |  |  |  | 27,714 |  |  |  | 27,040 |

We incurred non-GAAP net losses of $6.5 million and $13.3 million, or $0.23 and $0.48 per share, for the three and six months ended September 30, 2022, compared to $5.1 million and $7.8 million, or $0.19 and $0.29 per share, for the three and six months ended September 30, 2021. The increase in the non-GAAP net loss for the three and six months ended September 30, 2022 was due to a higher operating loss driven by lower gross margin and higher operating expenses.

Liquidity and Capital Resources

We have experienced recurring operating losses and, as of September 30, 2022, had an accumulated deficit of $1,039 million.

Our cash requirements depend on numerous factors, including the successful completion of our product development activities, our ability to commercialize our REG 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, expect to reduce our operating and capital spending to enhance liquidity.

In February 2021, we filed a shelf registration statement on Form S-3 that will expire in February 2024 (the “Form S-3”). The Form S-3 allows us to offer and sell from time-to-time up to $250 million of common stock, debt securities, warrants or units comprised of any combination of these securities. The Form S-3 is intended to provide us flexibility to conduct registered sales of our securities, subject to market conditions, in order to fund our future capital needs. The terms of any future offering under the Form S-3 will be established at the time of such offering and will be described in a prospectus supplement filed with the SEC prior to the completion of any such offering.

As of September 30, 2022, we had cash, cash equivalents and restricted cash of $37.4 million, compared to $49.5 million as of March 31, 2022, a decrease of $12.1 million. As of September 30, 2022, we had approximately $1.9 million of cash, cash equivalents, and restricted cash in foreign bank accounts. Our cash, cash equivalents, and restricted cash are summarized as follows (in thousands):

|  | September 30, 2022 |  |  | March 31, 2022 |
Cash and cash equivalents |  | $ | 27,811 |  |  | $ | 40,584 |
Restricted cash |  |  | 9,542 |  |  |  | 8,902 |
Total cash, cash equivalents, and restricted cash |  | $ | 37,354 |  |  | $ | 49,486 |

For the six months ended September 30, 2022, net cash used in operating activities was $11.6 million, compared to $11.7 million for the six months ended September 30, 2021. The decrease in net cash used in operations was due primarily to an increase in inventory purchases offset by accounts receivable collections in the six months ended September 30, 2022 as compared to September 30, 2021.

For the six months ended September 30, 2022, net cash used in investing activities was $0.7 million, compared to $6.8 million for the six months ended September 30, 2021. The decrease in net cash used in investing activities was primarily due to the cash that was used to pay for the Neeltran Acquisition in the six months ended September 30, 2021. There was no such transaction in the six months ended September 30, 2022.

For the six months ended September 30, 2022 and 2021, respectively, net cash provided by financing activities remained consistent at less than $0.1 million.

As of September 30, 2022, we had $6.0 million of restricted cash included in long-term assets and $3.6 million of restricted cash included in current assets. These amounts of restricted cash primarily represent deposits to secure letters of credit for various supply contracts and long-term projects, including the irrevocable letter of credit in the amount of $5.0 million to secure certain of our obligations under the Subcontract Agreement with ComEd. 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 consolidated balance sheet as of September 30, 2022, 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 13, "Contingent Consideration," Note 14, "Debt," Note 15, "Leases" and Note 16, "Commitments and Contingencies" to our condensed consolidated financial statements included elsewhere in this Quarterly Report on Form 10-Q.

We believe we have sufficient available liquidity to fund our operations and capital expenditures for the next twelve months. 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. Our liquidity is highly dependent on our ability to increase revenues, improve upon gross margins, control our operating costs, and raise additional capital, if necessary. 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 the COVID-19 pandemic and adverse macroeconomic conditions on the global financial markets may reduce our ability to raise additional capital, if necessary, which could negatively impact our liquidity.

Legal Proceedings

We are involved in legal and administrative proceedings and claims of various types. See Part II, Item 1, “Legal Proceedings,” for additional information. We record a liability in our 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 consolidated financial statements not misleading. If the loss is not probable or cannot be reasonably estimated, a liability is not recorded in our consolidated financial statements.

Recent Accounting Pronouncements

In June 2016, the FASB issued ASU 2016-13, Financial Instruments-Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments. The amendments in ASU 2016-13 will provide more decision-useful information about the expected credit losses on financial instruments and other commitments to extend credit held by a reporting entity at each reporting date. Following the release of ASU 2019-10 in November 2019, the new effective date, as long as we remain a smaller reporting company, would be annual reporting periods beginning after December 15, 2022. We have evaluated the impact of the adoption of ASU 2016-13, and do not expect it to have a material impact on our consolidated financial statements.

In October 2021, the FASB issued ASU 2021-08, Business Combinations (Topic 805): Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The amendments in ASU 2021-08 will improve the accounting for acquired revenue contracts with customers in a business combination. Following the release of ASU 2021-08 in October 2021, the new effective date will be annual reporting periods beginning after December 15, 2022. We are currently evaluating the impact, if any, that the adoption of ASU 2021-08 may have on our consolidated financial statements.

In November 2021, the FASB issued ASU 2021-10, Government Assistance (Topic 832): Disclosures by Business Entities about Government Assistance. The amendments in ASU 2021-10 improve financial reporting by requiring disclosures that increase the transparency of transactions with government accounted for by applying a grant or contribution accounting model by analogy. Following the release of ASU 2021-10 in November 2021, the effective date was annual reporting periods beginning after December 15, 2021. As of April 1, 2022, we have adopted ASU 2021-10 and noted no material 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 consolidated financial statements.

ITEM 4. | 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 September 30, 2022. 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 September 30, 2022, 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 September 30, 2022 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
