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 December 31, 2020 and 2019 and the financial position at December 31, 2020; 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, 2020, and notes thereto, included in the Company’s Annual Report on Form 10-K for the year ended March 31, 2020 filed with the SEC on June 2, 2020.

Liquidity

The Company has historically experienced recurring operating losses and as of December 31, 2020, the Company had an accumulated deficit of $993.7 million. In addition, the Company has historically experienced recurring negative operating cash flows.  At December 31, 2020, the Company had cash, cash equivalents, and marketable securities of $78.1 million. Marketable securities include certificate of deposits with maturities between three and nine months.  Cash used in operations for the nine months ended December 31, 2020 was $4.9 million.

In December 2015, the Company entered into a set of strategic agreements valued at approximately $210.0 million with Inox Wind Ltd. (“Inox” or “Inox Wind”), which includes a multi-year supply contract pursuant to which the Company will supply electrical control systems ("ECS") to Inox and a license agreement allowing Inox to manufacture a limited number of ECS. After Inox purchases the specified number of ECS required under the terms of the supply contract, Inox agreed that the Company will continue as Inox’s preferred supplier and Inox will be required to purchase from the Company a majority of its ECS requirements for an additional three-year period. Pursuant to these strategic agreements, Inox must forecast future purchase orders of sets of ECS which become firm orders three months prior to shipment, and Inox must post letters of credit before the Company will ship such orders. Inox had been delinquent on its obligation to post letters of credit for sets of ECS that Inox forecasted to purchase under the terms of the supply contract.  On May 29, 2020, the Company sent written notice to Inox notifying Inox of its default under the supply contract due to Inox’s failure to post letters of credit in the amount of €6.0 million for the payment of ECS that Inox is obligated to purchase under the terms of the supply contract.  If Inox failed to post letters of credit in the amount of €6.0 million in accordance with the terms of the supply contract within the ninety day cure period after receipt of the default notice, then the Company could have terminated the supply contract by providing written notice of such termination to Inox.  On September 2, 2020, Inox delivered approved letters of credit in the amount of €1.3 million for the payment of a portion of the ECS that Inox was obligated to purchase under the terms of the supply contract.  On September 11, 2020, the Company notified Inox that due to (i) the Company’s business relationship with Inox, and (ii) Inox’s delivery of approved letters of credit in the amount of €1.3 million as described above, the Company gave Inox until October 5, 2020 to regain compliance with the terms of the supply contract by providing approved letters of credit in the amount of €4.7 million for payment of the remaining ECS that Inox currently was obligated to purchase under the terms of the supply contract.  On October 1, 2020, Inox delivered approved letters of credit for payment of the remaining ECS that Inox was obligated to purchase under the terms of the supply contract and cured the default set forth in the May 29, 2020 default notice.

On October 1, 2020 (the "Acquisition Date"), the Company 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, 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 "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 now a wholly-owned subsidiary of the Company and is operated by its Grid business unit. The purchase price was $26.0 million in cash and 873,657 restricted shares of common stock of the Company.  As part of the transaction, 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 in the future.

On October 22, 2020, the Company entered into an underwriting agreement with Oppenheimer & Co. Inc., as representative of the several underwriters named therein, relating to the issuance and sale (the “Offering”) of 3,670,000 shares of the Company’s common stock at a public offering price of $15.00 per share. The net proceeds to the Company from the Offering were approximately $51.5 million, after deducting underwriting discounts and commissions and offering expenses payable by the Company. The Offering closed on October 26, 2020. In addition, the Company had granted the underwriters a 30-day option to purchase up to an additional 550,500 shares of common stock at the public offering price which was not exercised.

In March 2020, the World Health Organization declared the disease caused by the novel coronavirus, COVID-19, to be a pandemic. COVID-19 has spread throughout the globe, including in the Commonwealth of Massachusetts where the Company’s headquarters are located, and in other areas where the Company has business operations. In response to the outbreak, the Company has followed the guidelines of the U.S. Centers for Disease Control and Prevention and applicable state government authorities to protect the health and safety of the Company’s employees, families, suppliers, customers and communities. While these existing measures and, COVID-19 generally, have 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.

While the COVID-19 pandemic continues to rapidly evolve, the Company continues to assess the impact of the COVID-19 pandemic to best mitigate risk and continue the operations of the Company’s business. The extent to which the outbreak 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, including new information that may emerge concerning the severity of the COVID-19 pandemic and the actions to contain it or treat its impact, among others.  If the Company, its customers or suppliers experience prolonged shutdowns or other business disruptions, the Company’s business, liquidity, results of operations and financial condition are likely to be materially adversely affected, and the Company’s ability to access the capital markets may be limited. 

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 nine months ended December 31, 2020. The Company’s liquidity is highly dependent on its ability to increase revenues, including its ability to collect revenues under its agreements with Inox, its ability to control its operating costs, and its ability to raise additional capital, if necessary.  The impact of the COVID-19 pandemic 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. NEPSI Acquisition

Acquisition of NEPSI

As described in Note 1, Nature of the Business and Operations and Liquidity, on the Acquisition Date, the Company acquired all of the issued and outstanding shares of capital stock of NEPSI and membership interests of Northeast Power Realty, LLC, a New York limited liability company, which holds the real property that serves as NEPSI’s headquarters. 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 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 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 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 Acquisition completed by the Company during the nine months ended December 31, 2020 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 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 Accounting Standards Codification ("ASC 606") was completed as part of the Acquisition.  See Note 3 "Revenue Recognition" for further details.  There were no leases acquired and the 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

At the Acquisition Date, in addition to the $26.0 million cash, the Company valued the Company’s common stock, using $14.23 per share, which was the closing price on the day that the Company acquired NEPSI and $4.0 million of contingent consideration for the earnout liability valued as of the Acquisition Date. Acquisition costs of $0.3 million were recorded in selling, general and administrative ("SG&A") costs for the three and nine months ended December 31, 2020.

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, "Warrants and Derivative Liabilities" 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 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 three and nine months periods ended December 31, 2020 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 Acquisition was assigned to the Company’s Grid segment.  Goodwill recognized in the Acquisition is not deductible for tax purposes. This purchase price allocation is preliminary and has not been finalized as the analysis on the assets and liabilities acquired, primarily the tax related liability may require further adjustments to our purchase accounting that could result in a measurement period adjustment that would impact our reported net assets and goodwill as of October 1, 2020. Material changes, if any, to the preliminary allocation summarized above will be reported once the related uncertainties are resolved, but no later than October 1, 2021. The $1.7 million of deferred tax liability is primarily related to inventory step up and intangibles. 

Unaudited Pro Forma Operating Results

The unaudited pro forma condensed consolidated statement of operations for the three and nine months ended December 31, 2020 and 2019 is presented as if the Acquisition had occurred on April 1, 2019.

	Three Months Ended December 31,						Nine Months Ended December 31,
	2020			2019			2020			2019
Revenues	$	23,632		$	22,412		$	78,298		$	66,135

Shares - diluted		25,470			22,077			23,594			21,768

The pro forma amounts include the historical operating results of the Company and NEPSI with appropriate adjustments that give effect to acquisition related costs, income taxes, intangible amortization resulting from the Acquisition and certain conforming accounting policies of the Company.  The three and nine month periods ended December 31, 2020 include $2.7 million decrease in operating loss and net loss for the change in fair value on the contingent consideration.  The pro forma amounts are not necessarily indicative of the operating results that would have occurred if the Acquisition and related transactions had been completed at the beginning of the applicable periods presented. In addition, the pro forma amounts are not necessarily indicative of operating results in future periods.

In the unaudited consolidated results for the three and nine months ended December 31, 2020, NEPSI’s operations are included in the Company’s consolidated results from the date of Acquisition of October 1, 2020. NEPSI contributed $6.6 million of revenue and $0.1 million in net income for the Company for the three and nine month periods ended December 31, 2020.  Amortization expense of $0.5 million is included in the three and nine months ended December 31, 2020 as a result of the NEPSI acquired intangible assets.  In addition, $1.0 million for the step-up basis assigned to acquired inventory was charged to cost of revenues in the three and nine months ended December 31, 2020.

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 ASC 606, Revenue from Contracts with Customers. 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 nine months ended December 31, 2020, 78% and 79% 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 nine months ended December 31, 2019, 57% and 69%, respectively, of revenue was recognized at the point in time when control transferred to the customer, with the remainder being recognized over time.

Following the Acquisition of NEPSI, the Company evaluated all open NEPSI contracts at the date of the Acquisition against a five-step model in accordance with ASC 606 as NEPSI, as a private company, had deferred adopting ASC606 prior to the Acquisition, as permitted.  The Company identified two NEPSI revenue streams which are (1) the sale of its major components which falls under the equipment and systems product line and (2) the sale of spare parts, which falls under the service product line.  Further details on each of these product lines can be found below.  The Company does not expect a material impact to its consolidated statements of operations on an ongoing basis resulting from the adoption of the ASC 606 standard for the NEPSI business, and NEPSI revenue streams will follow the existing policies noted below. 

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.  In the three and nine months ended December 31, 2020, the Company recorded $1.1 million and $1.8 million in grant revenue, respectively, which is included in the Company’s Grid segment revenue.  In the three and nine months ended December 31, 2019, the Company recorded $3.9 million and $5.3 million in grant revenue, respectively, which is included in the Company’s Grid 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 the profit 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 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.

9

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.  

The following tables disaggregate the Company’s revenue by product line and by shipment destination:

As of December 31, 2020, and 2019, 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:

	Unbilled Accounts Receivable			Deferred Program Costs			Contract Liabilities
Beginning balance as of March 31, 2020	$	5,711		$	1,631		$	26,142
Increases for costs incurred to fulfill performance obligations		—			6,635			—
Increase for balances acquired		101			—			2,700
Increase (decrease) due to customer billings		(8,255	)		—			42,785
Decrease due to cost recognition on completed performance obligations		—			(6,969	)		—
Increase (decrease) due to recognition of revenue based on transfer of control of performance obligations		6,644			—			(48,274	)

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 December 31, 2020, the Company had outstanding performance obligations on existing contracts under ASC 606 to be recognized in the next twelve months of approximately $51.1 million. There are also approximately $7.2 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 nine months ended December 31, 2020 and 2019:

		Three Months Ended						Nine Months Ended
	Reportable	December 31,						December 31,
	Segment	2020			2019			2020			2019
Inox Wind Limited	Wind		24	%		<10%			12	%		11	%
Department of Homeland Security	Grid		<10%			22	%		<10%			12	%
Vestas	Grid		<10%			25	%		<10%			10	%
EPC Services	Grid		14	%		<10%			17	%		<10%

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 nine months ended December 31, 2020 and 2019 (in thousands):

	Three Months Ended December 31,					Nine Months Ended December 31,
	2020			2019		2020		2019
Cost of revenues	$	(23	)	$	21	$	35	$	45
Research and development		179			117		470		219
Selling, general and administrative		683			452		2,092		971
Total	$	839		$	590	$	2,597	$	1,236

The Company issued 27,341 shares of immediately vested common stock and 697,167 shares of restricted stock awards during the nine months ended December 31, 2020 and issued 13,174 shares of immediately vested common stock and 366,000 shares of restricted stock awards during the nine months ended December 31, 2019.  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 outstanding stock options was less than $0.1 million at December 31, 2020. This expense will be recognized over a weighted average expense period of approximately 0.4 years. The total unrecognized compensation cost for unvested outstanding restricted stock was $5.2 million at December 31, 2020. This expense will be recognized over a weighted-average expense period of approximately 1.9 years.

The Company did not grant any stock options during the nine months ended December 31, 2020.  The Company granted 5,939 stock options during the nine months ended December 31, 2019.  The stock options granted during the nine months ended December 31, 2019 will vest over 2 years. The weighted average assumptions used in the Black Scholes valuation model for stock options granted during the nine months ended December 31, 2019 are as follows:

	Three Months Ended December 31,				Nine Months Ended December 31,
	2020		2019		2020		2019
Expected volatility		N/A		N/A		N/A		66.5	%
Risk-free interest rate		N/A		N/A		N/A		1.8	%
Expected life (years)		N/A		N/A		N/A		5.91
Dividend yield		N/A		N/A		N/A	None

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 the three and nine months ended December 31, 2020, 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. For the three and nine months ended December 31, 2019, 0.1 million shares related to outstanding stock options were not included in the calculation of diluted EPS as they were considered anti-dilutive.

The following table reconciles the numerators and denominators of the earnings per share calculation for the three and nine months ended December 31, 2020 and 2019 (in thousands, except per share data):

	Three Months Ended December 31,						Nine Months Ended December 31,

Net loss per share ― diluted	$	(0.31	)	$	(0.35	)	$	(0.65	)	$	(0.75	)

For the three and nine months ended December 31, 2019, the diluted net loss per common share amounts under the treasury stock method were calculated based on the dilutive effect of the total number of shares of common stock related to the warrants issued to Hudson Bay Capital (the “Hudson Warrants”) for 818,181 shares with an exercise price of $7.81.  For the three and nine month periods ended December 31, 2019, the average stock price was $8.19 and $9.29 respectively through November 13, 2019 when the Hudson Warrant was partially exercised for 786,000 shares, providing 37,962 and 130,345 dilutive shares respectively. The increase of $0.6 million and the decrease of $4.6 million in the fair value of the warrant liability, respectively, is included in the net loss available to common shareholders for the diluted net loss per common share amount when the impact is dilutive. 

6. Goodwill and Other Intangibles

Goodwill

The guidance under ASC 805-30 provides for the recognition of goodwill on the Acquisition Date measured as the excess of the aggregate consideration transferred over the net of the Acquisition Date amounts of net assets acquired and liabilities assumed. The Company's goodwill balance relates to the Acquisition of NEPSI in the current year and ITC in fiscal 2017 and is reported in the Grid business segment.  The fair market value of the contingent consideration included in the total consideration transferred was determined using the Monte Carlo model, and all other consideration transferred was calculated using its observable fair market value. The tangible net assets acquired fair market value was based on observable market fair value. The acquired intangible asset fair value was determined using discounted cash flows under an excess in earnings model or relief in royalty method where appropriate.

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. 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 our Grid business segment goodwill balance:

	Goodwill
March 31, 2020	$	1,719
NEPSI Acquisition		32,940
Less impairment loss		-
December 31, 2020	$	34,659

The Company did not identify any triggering events in the three and nine months ended December 31, 2020, that would require interim impairment testing of goodwill.

Other Intangibles

Intangible assets at December 31, 2020 and March 31, 2020 consisted of the following (in thousands):

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 nine months ended December 31, 2020.

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 recognized no change in the three months ended December 31, 2020 and $0.2 million in unrealized losses on marketable securities, which is recorded in other income (expense), net, for the nine months ended December 31, 2020 and less than a $0.1 million gain which was recognized during the nine months ended December 31, 2020 upon the sale of one of the certificates of deposit.  The Company did not recognize any gains or losses on marketable securities in the three and nine months endedDecember 31, 2019.  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 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 Acquisition Date. See Note 13, "Warrants and Derivative Liabilities" and Note 2, “NEPSI Acquisition” for further discussion. The Company relied on a Monte Carlo method to determine the fair value of the contingent consideration on the 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. 

Warrants

The Company issued the Hudson Warrants in conjunction with an equity offering to Hudson Bay Capital in November 2014 and issued warrants to purchase 58,823 shares of the Company's common stock in conjunction a Loan and Security Agreement with Hercules Technology Growth Capital, Inc. (“Hercules Warrants”). The Hercules Warrants were exercised on April 8, 2019.  The Hudson Warrants were partially exercised on November 13, 2019 and the remaining unexercised warrants expired on November 13, 2019.  As of December 31, 2020, the Company has no remaining outstanding warrants.

The Company historically relied on various assumptions in a lattice model to determine the fair value of warrants. The Company had valued the warrants within Level 3 of the valuation hierarchy. See Note 13, “Warrants and Derivative Liabilities,” for a discussion of the warrants and the valuation assumptions used.

The following table provides the assets and liabilities carried at fair value on a recurring basis, measured as of December 31, 2020 and March 31, 2020 (in thousands):

The Company recorded inventory write-downs of $0.4 million and $0.3 million for the three months ended December 31, 2020 and 2019, respectively.  The Company recorded inventory write-downs of $1.6 million and $0.5 million for the nine months ended December 31, 2020 and 2019, respectively.  These write-downs were based on the Company's evaluation of its inventory on hand for excess quantities and obsolescence.

Deferred program costs as of December 31, 2020 and March 31, 2020 primarily represent costs incurred on programs where the Company needs to complete performance obligations before the related revenue and costs will be recognized.

10. Property, Plant and Equipment

The cost and accumulated depreciation of property, plant and equipment at December 31, 2020 and March 31, 2020 are as follows (in thousands):

	December 31, 2020			March 31, 2020

Depreciation expense was $2.9 million and $3.1 million for the nine months ended December 31, 2020 and 2019, respectively.  The decrease in construction in progress primarily relates to the completion of capital investments in the Company's HTS equipment and leasehold improvements in the Company's leased facilities in Westminster and Ayer, Massachusetts.  The increase in land and building relates to the property added as part of the NEPSI Acquisition.

11. Accounts Payable and Accrued Expenses

Accounts payable and accrued expenses at December 31, 2020 and March 31, 2020 consisted of the following (in thousands):

	December 31, 2020		March 31, 2020

12. Income Taxes

The Company recorded an income tax benefit of $1.5 million and $1.2 million in the three and nine month periods ended December 31, 2020, respectively. The Company recorded income tax expense of $0.1 million in the three months ended December 31, 2019, and less than $0.1 million in the nine months ended December 31, 2019.

As a result of a difference in book and tax basis related to the intangible assets acquired in the Acquisition (see Note 2, "NEPSI Acquisition"), the Company recorded a deferred tax liability of $1.7 million. As a result, the Company was able to benefit from additional deferred tax assets and therefore released a corresponding valuation allowance of $1.7 million during the three and nine months ended December 31, 2020.  The purchase price allocation is preliminary and has not been finalized as the analysis on the assets and liabilities acquired, primarily the tax related liability, may require further adjustments to the Company's purchase accounting that could result in measurement period adjustments that would impact the Company's reported net assets and goodwill as of October 1, 2020. Material changes, if any, to the preliminary allocation summarized in Note 2, "NEPSI Acquisition" will be reported once the related uncertainties are resolved, but no later than October 1, 2021.  Goodwill recognized in the Acquisition is not deductible for tax purposes.

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 nine months ended December 31, 2020 and did not have any gross unrecognized tax benefits as of March 31, 2020.

13. Warrants and Derivative Liabilities

Contingent Consideration

The Company evaluated the Acquisition earnout payment set forth in the Stock Purchase Agreement (see Note 2, "NEPSI Acquisition" 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 Acquisition:

	December 31,			October 1,
Fiscal Year 2020	2020			2020
Revenue risk premium		6.90	%		7.10	%
Revenue volatility		30	%		30	%
Stock Price	$	23.42		$	14.23
Payment delay (days)		80			—
Fair value	$6.7 million			$4.0 million

The Company recorded a net loss of $2.7 million resulting from the increase in the fair value of the contingent consideration in both the three and nine months ended December 31, 2020.

Warrants

The Company accounted for its warrants as liabilities due to certain adjustment provisions within the instruments, which required that they be recorded at fair value. The warrants were subject to revaluation at each balance sheet date and any change in fair value was recorded as a change in fair value of warrants until the earlier of its expiration or its exercise at which time the warrant liability was reclassified to equity. The Company calculated the fair value of the warrants utilizing an integrated lattice model. See Note 7, "Fair Value Measurements", for further discussion.  As of December 31, 2020, the Company had no remaining outstanding warrants.

Hercules Warrants

On December 19, 2014, the Company entered into a second amendment to the Loan and Security Agreement with Hercules (the "Hercules Second Amendment"). In conjunction with the Hercules Second Amendment, the Company issued the Hercules Warrant which replaced the First Warrant and the Second Warrant.  The Hercules Warrant was exercisable at any time after its issuance at an exercise price of $7.85 per share, subject to certain price-based and other anti-dilution adjustments, including the equity offering in May 2017, the acquisition of Infinia Technology Corporation ("ITC") with common stock in September 2017 and sales of common stock under the ATM entered into in January 2017.  This warrant had a fair value of $0.4 million as of March 31, 2019.  On April 8, 2019, Hercules notified the Company of its intent to exercise this warrant on a cashless basis.  Hercules received 22,821 shares of the Company's common stock on April 17, 2019.  As a result of this exercise the Company recorded a net gain of $0.1 million to change in fair value of warrants, resulting from the decrease in the fair value of the Hercules Warrant during the nine months ended December 31, 2019.  

November 2014 Warrant

On November 13, 2014, the Company completed an offering of 909,090 units of the Company’s common stock with Hudson Bay Capital. Each unit consisted of one share of the Company’s common stock and 0.9 of a warrant to purchase one share of common stock, or a warrant to purchase in the aggregate 818,181 shares.  The Hudson Warrants were exercisable at any time, at an exercise price equal to $7.81 per share, subject to certain price-based and other anti-dilution adjustments including those noted above.  On November 13, 2019, Hudson partially exercised the Hudson Warrants for 786,000 restricted shares of Company common stock at $7.81 per share.  The remaining 32,181 warrants expired on November 13, 2019. The Company recorded net gains of $0.5 million and $4.6 million to change in fair value of warrants, resulting from the decrease in the fair value of the Hudson Warrants during the three and nine months ended December 31, 2019, respectively.

14. Leases

On April 1, 2019, the Company adopted ASU 2016-02, Leases (Topic 842) ("ASC 842"), using the modified retrospective approach. The Company elected the package of practical expedients available in the standard and as a result, did not reassess the lease classification of existing contracts or leases or the initial direct costs associated with existing leases. The Company did not elect the hindsight practical expedient and evaluated lease terms for existing leases. The Company has also elected the practical expedient to not separate lease components and non-lease components and will account for the leases as a single lease component for all classes of 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. 

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.

The Company did not identify any leases that are classified as financing leases.

Supplemental balance sheet information related to leases at December 31, 2020 and March 31, 2020 are as follows:

	December 31, 2020			March 31, 2020
Operating Leases:

15. 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 December 31, 2020, and March 31, 2020, the Company had $5.6 million of restricted cash included in long-term assets and $0.6 million of restricted cash included in current assets, respectively. 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 the Subcontract Agreement with ComEd.  These deposits are held in interest bearing accounts.

16. 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 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.

The operating results for the two business segments are as follows (in thousands):

	Three Months Ended December 31,				Nine Months Ended December 31,
	2020		2019		2020		2019
Revenues:
Grid	$	17,086	$	15,232	$	51,149	$	36,577

Unallocated corporate expenses		(3,579	)		(590	)		(5,337	)		(1,236	)
Total	$	(9,258	)	$	(6,619	)	$	(15,681	)	$	(16,974	)

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 primarily of loss on contingent consideration of $2.7 million in both the three and nine months ended December 31, 2020. Additionally, unallocated corporate expenses consist of stock-based compensation expense of $0.8 million and $0.6 million in the three months ended December 31, 2020 and 2019, respectively, and $2.6 million and $1.2 million in the nine months ended December 31, 2020 and 2019, respectively.

Total assets for the two business segments as of December 31, 2020 and March 31, 2020 are as follows (in thousands):

	December 31, 2020		March 31, 2020
Grid	$	83,623	$	44,044

17. 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. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that year.  Following the release of ASU 2019-10 in November 2019, the new effective date, as long as the Company remains a smaller reporting company, would be annual reporting periods beginning after December 15, 2022.  The Company is currently evaluating the impact, if any, that the adoption of ASU 2016-13 may have on its consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in ASU 2018-13 provide for increased effectiveness of the disclosures made around fair value measurements while including consideration for costs and benefits. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those periods. As of April 1, 2020, the Company has adopted ASU 2018-13 and noted no material impact on its consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 provide for simplified accounting to several income tax situations and removal of certain accounting exceptions. The ASU is effective for annual reporting periods beginning after December 15, 2020, including interim periods within those periods. The Company does not expect the impact of the adoption of ASU 2019-12 to be material to its consolidated financial statements.

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 drive trains and power ratings of 2 megawatts (“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 beginning on April 1 of that same year. For example, fiscal 2020 refers to the fiscal year beginning on April 1, 2020. 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 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 have 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 expect funding provided by DHS in connection with the Subcontract Agreement to be between $9.0 to $11.0 million, which represents the total amount of revenue we are expected to recognize over the term of the Subcontract Agreement and includes up to $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 installation, 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 have delivered the REG project hardware. The REG system is expected to be operational in 2021.

On October 1, 2020, 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 (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 "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.  As a result of this transaction, NEPSI became a wholly-owned subsidiary and will be operated by our Grid business segment.

The NEPSI purchase price was $26.0 million in cash on hand, including cash from the settlement of our $25 million certificate of deposit during the three months ended September 30, 2020, and 873,657 restricted shares of our common stock.  As part of the transaction, in the future, the selling stockholders may receive up to an additional 1,000,000 million restricted shares of our common stock upon the achievement of certain specified future revenue objectives during varying periods of up to four years after the closing.

On October 26, 2020, we completed the Offering of 3,670,000 shares of our common stock at a public offering price of $15.00 per share. We received net proceeds of approximately $51.5 million after deducting underwriting discounts and commissions and offering expenses.  See Note 1, “Nature of the Business and Operations and Liquidity,” for further information about this offering.

In March 2020, the World Health Organization declared the disease caused by the novel coronavirus, COVID-19 to be a pandemic. COVID-19, has spread throughout the globe, including in the Commonwealth of Massachusetts where our headquarters are located, and in other areas where we have business operations. In response to the outbreak, we have followed the guidelines of the U.S. Centers for Disease Control and Prevention and applicable state government authorities to protect the health and safety of our employees, their families, our suppliers, our customers and our communities. While these existing measures and, COVID-19 generally, have not materially disrupted our business to date, any future actions necessitated by the COVID-19 pandemic may result in disruption to our business.

The COVID-19 pandemic continues to rapidly evolve. The extent to which the outbreak 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, including new information that may emerge concerning the severity of the COVID-19 pandemic and the actions to contain it or treat its impact, among others.

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 Form 10-K for the fiscal year ended March 31, 2020.

Results of Operations

Three and nine months ended December 31, 2020 compared to the three and nine months ended December 31, 2019

Revenues

Total revenues increased 32% and 44% to $23.6 million and $66.0 million for the three and nine months ended December 31, 2020, respectively, compared to $17.9 million and $45.7 million for the three and nine months ended December 31, 2019, respectively.  Our revenues are summarized as follows (in thousands):

	Three Months Ended December 31,				Nine Months Ended December 31,
	2020		2019		2020		2019
Revenues:
Grid	$	17,086	$	15,232	$	51,149	$	36,577
Wind		6,546		2,683		14,812		9,120
Total	$	23,632	$	17,915	$	65,961	$	45,697

Our Grid business unit accounted for 72% and 78% of total revenues for the three and nine months ended December 31, 2020, respectively, compared to 85% and 80% for the three and nine months ended December 31, 2019, respectively. Our Grid business unit revenues increased 12% and 40% to $17.1 million and $51.1 million in the three and nine months ended December 31, 2020, respectively, from $15.2 million and $36.6 million in the three and nine months ended December 31, 2019, respectively.  Grid business unit revenue in the three months ended December 31, 2020 was driven by the acquisition of NEPSI and its accompanying revenue and stronger ship protection systems revenue.  Grid business unit revenue in the nine months ended December 31, 2020 was driven by stronger D-VAR, VVO and ship protection systems revenue as well as the acquisition of NEPSI.

Our Wind business unit accounted for 28% and 22% of total revenues for the three and nine months ended December 31, 2020, respectively, compared to 15% and 20% for the three and nine months ended December 31, 2019, respectively. Revenues in the Wind business unit increased 144% and 62% to $6.5 million and $14.8 million in the three and nine months ended December 31, 2020, from $2.7 million and $9.1 million in the three and nine months ended December 31, 2019. The increase in the three months ending December 31, 2020 was driven by increased shipments of electrical control systems ("ECS") to Inox.   The increase in the nine months ending December 31, 2020 was due to increased shipments of ECS to Inox and an increase in spares revenue.  As further described in Note 1 “Nature of the Business and Operations and Liquidity,” Inox was delinquent on its obligations to post letters of credit for sets of ECS that Inox has agreed to purchase under the terms of the supply contract, and on May 29, 2020, we sent written notice to Inox notifying Inox of its default under the supply contract due to Inox’s failure to post letters of credit in the amount of €6.0 million for the payment of ECS that Inox is obligated to purchase under the terms of the supply contract. On October 1, 2020, Inox delivered approved letters of credit for payment of the remaining ECS that Inox had been obligated to purchase under the terms of the Supply Contract and cured the default set forth in the May 29, 2020 default notice.  Despite curing the default, Inox’s ability to perform under the supply contract has been and may continue in the future to be hampered by the prolonged impacts of the COVID-19 pandemic. Inox has been active in the new central and state government auction regime in India and has a cumulative order book of over 1.4 GW.  However, we cannot predict if and how successful Inox will be in executing on these orders or in obtaining new orders under the new central and state auction regime. Any failure by Inox to succeed under this regime, or any delay in Inox’s ability to deliver its wind turbines, could result in fewer ECS shipments to Inox.

Cost of Revenues and Gross Margin

Cost of revenues increased by 20% and 33% to $19.7 million and $51.4 million for the three and nine months ended December 31, 2020, compared to $16.3 million and $38.8 million for the three and nine months ended December 31, 2019. Gross margin was 17% and 22% for the three and nine months ended December 31, 2020, compared to 9% and 15% for the three and nine months ended December 31, 2019.  The increase in gross margin in the three and nine months ended December 31, 2020 was due to higher revenue and a more favorable product mix.  Cost of revenues includes amortization expense of $0.3 million in the three and nine months ended December 31, 2020 as a result of the NEPSI acquired backlog intangible asset.  In addition, a fair value purchase adjustment of approximately $1.0 million 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, 2020. The step up was assigned to acquired work-in-progress and finished goods inventory that was completely delivered in the three and nine months period ended December 31, 2020.

23

Operating Expenses

Research and development

Research and development ("R&D") expenses increased 48% in the three months ended December 31, 2020 to $3.0 million from $2.0 million in the three months ended December 31, 2019.  The increase in R&D expense was due to higher overall compensation expense and less allocation of expenses to cost of goods sold for revenue generating projects in the three months ended December 31, 2020 compared to the three months ended December 31, 2019.  Research and development expenses increased 19% in thenine months endedDecember 31, 2020 to $8.2 million from $6.9 million in the nine months ended December 31, 2019. The increase in R&D expense in the nine month period was due to higher overall compensation expense and less allocation of expenses to cost of goods sold for revenue generating projects than in the prior year period.

Selling, general, and administrative

Selling, general and administrative ("SG&A") expenses increased 17% in the three months ended December 31, 2020 to $7.1 million from $6.1 million in the three months ended December 31, 2019. The increase in SG&A expense in the three months ended December 31, 2020 was due to higher overall compensation expense, including stock compensation, than in the prior year period.  SG&A expenses increased 11% to $18.6 million in the nine months ended December 31, 2020 compared to $16.7 million in the nine months ended December 31, 2019. The increase in SG&A expense in the nine months endedDecember 31, 2020 was due to higher overall compensation expense, including stock compensation, 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 $0.4 million and $0.1 million in the three month periods ended December 31, 2020 and 2019, respectively, and $0.6 million and $0.3 million in the nine month periods ended December 31, 2020 and 2019 respectively.  The increases in amortization expense in both periods are primarily a result of the acquisition of NEPSI.

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 loss of $2.7 million in both the three and nine months ended December 31, 2020. The change in the fair value was primarily driven by the change in our stock price, which is a key valuation metric.

Operating loss

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

	Three Months Ended December 31,						Nine Months Ended December 31,
	2020			2019			2020			2019
Operating profit (loss):
Grid	$	(5,826	)	$	(3,732	)	$	(8,388	)	$	(9,723	)
Wind		147			(2,297	)		(1,956	)		(6,015	)
Unallocated corporate expenses		(3,579	)		(590	)		(5,337	)		(1,236	)
Total	$	(9,258	)	$	(6,619	)	$	(15,681	)	$	(16,974	)

Our Grid segment generated operating losses of $5.8 million and $8.4 million in the three and nine months ended December 31, 2020, compared to $3.7 million and $9.7 million in the three and nine months ended December 31, 2019. The increase in the Grid business unit operating loss in the three months ended December 31, 2020 was due a less favorable product mix and the impact of the purchase accounting adjustments recorded as part of the NEPSI Acquisition including the inventory step up charge noted above and an adjustment to revenue of $0.3 million less than the contract value, for recognition of the fair value adjustment that reduced acquired customer deposits to properly reflect pre-acquisition activities.  The decrease in the Grid business unit operating loss in the nine months ended December 31, 2020 was due to higher revenues and a more favorable product mix.

Our Wind segment generated an operating profit of $0.1 million and an operating loss of $2.0 million in the three and nine months ended December 31, 2020, compared to operating losses of $2.3 million and $6.0 million in the three and nine months ended December 31, 2019. The decrease in the Wind business unit operating loss in both periods was due to higher revenues.

Unallocated corporate expenses consist of a loss on contingent consideration of $2.7 million in both the three and nine months ended December 31, 2020. Additionally, unallocated corporate expenses consisted of stock-based compensation expense of $0.8 million and $0.6 million in the three months ended December 31, 2020 and 2019, respectively.  Unallocated corporate expenses consisted of stock-based compensation expense of $2.6 million and $1.2 million in the nine months ended December 31, 2020 and 2019, respectively.

Change in fair value of warrants

There were no warrants outstanding in the three and nine months ended December 31, 2020. The change in fair value of warrants resulted in gains of $0.6 million and $4.6 million in the three and nine months ended December 31, 2019. The change in the fair value was primarily driven by changes in stock price, which is a key valuation metric.

24

Interest income, net

Interest income, net, was $0.1 million and $0.4 million in the three and nine months ended December 31, 2020, compared to $0.3 million and $1.1 million in the three and nine months ended December 31, 2019. The decreases in interest income in the three and nine months ended December 31, 2020 were related to lower cash balances earning lower interest rates than in the prior periods, as well as interest recorded related to the sale of the Devens facility for the nine months ended December 31, 2019 with no such transaction in the current year.

Other (expense) income, net

Other expense, net, was $0.3 million and $0.9 million in the three and nine months ended December 31, 2020, compared to other expense, net of $0.9 million and other income, net of less than $0.1 million in the three and nine months ended December 31, 2019.  The changes in other expense, net, during both periods was driven by the impacts of fluctuations in foreign currencies during the respective period.  

 Income Taxes

Income tax benefit was $1.5 million and $1.2 in the three and nine months ended December 31, 2020, respectively.  Income tax expense was $0.1 million and less than $0.1 million in the three and nine months ended December 31, 2019, respectively. The decrease in income tax expense in both periods is a result of purchase accounting for the acquired intangible assets and the resulting deferred tax liability in the NEPSI Acquisition.  The Company recorded a deferred tax liability of $1.7 million, primarily for the difference in book and tax basis on the intangibles during the three months ended December 31, 2020. As a result, the Company was able to benefit additional deferred tax assets and therefore released a corresponding valuation allowance of $1.7 million during the three and nine months ended December 31, 2020.

Net loss

Net loss was $7.9 million and $15.1 million in the three and nine months ended December 31, 2020, compared to $6.8 million and $11.2 million in the three and nine months ended December 31, 2019.  The increases in net loss were driven by the change in fair value of contingent consideration loss in the three and nine months ended December 31, 2020, the gain on fair value of warrants in the prior year period that did not recur in the nine months ended December 31, 2020 as well as the changes discussed above.  

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 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 stock-based compensation, amortization of acquisition-related intangibles, acquisition costs, change in fair value of contingent consideration and warrants, 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 December 31,						Nine Months Ended December 31,
	2020			2019			2020			2019
Net loss	$	(7,933	)	$	(6,845	)	$	(15,062	)	$	(11,209	)
Stock-based compensation		839			590			2,597			1,236
Amortization of acquisition-related intangibles		645			85			886			255
Acquisition costs		313			—			313			—
Change in fair value of contingent consideration and warrants		2,740			(556	)		2,740			(4,648	)
Non-GAAP net loss	$	(3,395	)	$	(6,726	)	$	(8,526	)	$	(14,366	)
Non-GAAP net loss per share - basic	$	(0.13	)	$	(0.32	)	$	(0.37	)	$	(0.69	)
Weighted average shares outstanding - basic		25,470			21,185			23,011			20,786

We incurred non-GAAP net losses of $3.4 million and $8.5 million or $0.13 and $0.37 per share, for the three and nine months ended December 31, 2020, compared to $6.7 million and $14.4 million, or $0.32 and $0.69 per share, for the three and nine months ended December 31, 2019. The decrease in the three and nine month non-GAAP net loss was due to lower operating loss driven by higher revenues and a more favorable product mix.  

For a description and reconciliation of our other non-GAAP financial measure, non-GAAP operating cash flow, see below under “Non-GAAP Financial Measure – Non-GAAP Operating Cash Flow.”

Liquidity and Capital Resources

We have experienced recurring operating losses, and as of December 31, 2020, had an accumulated deficit of $993.7 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 further reduce our operating and capital spending to enhance liquidity.

As described above, on October 1, 2020, we acquired NEPSI. The NEPSI purchase price was $26.0 million in cash, including cash from the settlement of our $25 million certificate of deposit during the three months ended September 30, 2020, and 873,657 restricted shares of our common stock.  As part of the transaction, the selling stockholders may receive up to an additional 1,000,000 restricted shares of our common stock upon the achievement of certain specified revenue objectives in the future.

As described above, on October 26, 2020, we completed an offering of 3,670,000 shares of our common stock at a public offering price of $15.00 per share. We received net proceeds of approximately $51.5 million after deducting underwriting discounts and commissions and offering expenses.  In addition, we had granted the underwriters a 30-day option to purchase up to an additional 550,500 shares of common stock at the public offering price which they did not exercise.

As of December 31, 2020, we had cash, cash equivalents, marketable securities and restricted cash of $84.4 million, compared to $66.1 million as of March 31, 2020, an increase of $18.3 million. As of December 31, 2020, we had approximately $2.8 million of cash, cash equivalents, and restricted cash in foreign bank accounts. Our cash, cash equivalents, marketable securities and restricted cash are summarized as follows (in thousands):

	December 31, 2020		March 31, 2020
Cash and cash equivalents	$	67,909	$	24,699
Marketable securities		10,239		35,195
Restricted cash		6,233		6,165
Total cash, cash equivalents, marketable securities and restricted cash	$	84,381	$	66,059

For the nine months ended December 31, 2020, net cash used in operating activities was $4.9 million, compared to $17.8 million for the nine months ended December 31, 2019.  The decrease in net cash used in operations was due primarily to the overall impact of increased sales activities on the operating accounts in the current year period.

For the nine months ended December 31, 2020, net cash used in investing activities was $2.6 million, compared to net cash used in investing activities of $34.9 million for the nine months ended December 31, 2019. The decrease in net cash used in investing activities was due primarily to the purchase of the $35.0 million certificate of deposit in the nine months ended December 31, 2019 with no such transaction in the current year period and the sale of the $25.0 million certificate of deposit in the nine months ended December 31, 2020, offset by cash that was used to pay for the Acquisition. 

For the nine months ended December 31, 2020, net cash provided by financing activities was $50.6 million compared to net cash provided by financing activities of $5.7 million in the nine months ended December 31, 2019.  The increase in net cash provided by financing activities was due primarily to the proceeds from the October 2020 offering.

As of December 31, 2020, we had $5.6 million of restricted cash included in long-term assets and $0.6 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 our obligations under the Subcontract Agreement with ComEd. These deposits are held in interest bearing accounts.

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. We have no outstanding warrants as of December 31, 2020. Our liquidity is highly dependent on our ability to increase revenues, including our ability to collect revenues under our agreements with Inox, 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 on the global financial markets may reduce our ability to raise additional capital, if necessary, which could negatively impact our liquidity.

Non-GAAP Financial Measure – Non-GAAP Operating Cash Flow

We define non-GAAP operating cash flow as operating cash flow before the Sinovel settlement (net of legal fees and expenses); and other unusual cash flows or items. We believe non-GAAP operating cash flow assists management and investors in comparing our operating cash flow across reporting periods on a consistent basis by excluding these non-recurring cash items that we do not believe are indicative of our core operating cash flow. A reconciliation of GAAP to non-GAAP operating cash flow is set forth in the table below (in thousands).

	Nine months ended
	December 31, 2020			December 31, 2019
Operating cash flow	$	(4,871	)	$	(17,779	)
Sinovel settlement (net of legal fees and expenses)		—			1,000
Tax effect of adjustments		—			2,724
Non-GAAP operating cash flow	$	(4,871	)	$	(14,055	)

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.

Off-Balance Sheet Arrangements

We do not have any off-balance sheet arrangements, as defined under SEC rules, such as relationships with unconsolidated entities or financial partnerships, which are often referred to as structured finance or special purpose entities, established for the purpose of facilitating transactions that are not required to be reflected on our balance sheet except as discussed below.

We occasionally enter into construction contracts that include a performance bond. As these contracts progress, we continually assess the probability of a payout from the performance bond. Should we determine that such a payout is probable, we would record a liability.

In addition, we have various contractual arrangements under which we have committed to purchase minimum quantities of goods or services on an annual basis.

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 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. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within that year.  Following the release of ASU 2019-10 in November 2019, the new effective date, as long as the Company remains a smaller reporting company, would be annual reporting periods beginning after December 15, 2022.   We are currently evaluating the impact, if any, that the adoption of ASU 2016-13 may have on our consolidated financial statements.

In August 2018, the FASB issued ASU 2018-13, Fair Value Measurement (Topic 820): Changes to the Disclosure Requirements for Fair Value Measurement. The amendments in ASU 2018-13 provide for increased effectiveness of the disclosures made around fair value measurements while including consideration for costs and benefits. The ASU is effective for annual reporting periods beginning after December 15, 2019, including interim periods within those periods.  As of April 1, 2020, we have adopted ASU 2018-13 and noted no material impact on our consolidated financial statements.

In December 2019, the FASB issued ASU 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes. The amendments in ASU 2019-12 provide for simplified accounting to several income tax situations and removal of certain accounting exceptions. The ASU is effective for annual reporting periods beginning after December 15, 2020, including interim periods within those periods. We do not expect the impact of the adoption of ASU 2019-12 to be material to 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 December 31, 2020. 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.

In making this evaluation, our management considered the material weakness in our internal control over financial reporting described below. Based on such evaluation, our Chief Executive Officer and Chief Financial Officer have concluded that our disclosure controls and procedures were not effective at the reasonable assurance level as of such date.

Material Weakness

A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of the annual or interim financial statements will not be prevented or detected on a timely basis. During the third quarter of fiscal 2020, in connection with the preparation of our financial statements for this Quarterly Report on Form 10-Q, management identified the following material weakness: we did not maintain proper controls, processes and procedures  over the initial purchase accounting and the continuing fair value accounting associated with the NEPSI Acquisition that were adequately designed, documented and executed to support the accurate and timely reporting of our financial results regarding the initial purchase accounting and the continuing fair value accounting associated with the NEPSI Acquisition. Specifically, the modeling assumptions and the calculation performed by our third-party valuation specialist as it relates to fair value accounting reporting for contingent consideration on the purchase accounting for the NEPSI Acquisition included errors resulting in a $1.3 million overstatement in both the fair value of the earnout payment and the preliminary estimated purchase price paid to NEPSI, that we failed to detect, which were reflected in Exhibit 99.3 of our Form 8-K/A filed with the Securities and Exchange Commission (“SEC”) on December 14, 2020.  As a result, we made post-closing adjustments necessary to properly reflect the fair value of the contingent consideration liability in the financial statements included in this Quarterly Report on Form 10-Q for the period ended December 31, 2020.

Notwithstanding the material weakness, we believe that our financial statements contained in this Quarterly Report on Form 10-Q fairly present our financial position, results of operations and cash flows for the periods covered by this report in all material respects.

Our management, with the oversight of our audit committee, has initiated steps and plans to take additional measures to remediate the underlying causes of the material weakness, which we currently believe will be primarily through the development and implementation of new procedures, policies, processes, including revising precision level of management review controls and gaining additional assurance regarding timely completion of our outside service providers’ quality control procedures. It is possible that we may determine that additional remediation steps will be necessary in the future.

Changes in Internal Control over Financial Reporting

Other than the material weakness described above, there were no changes in 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, 2020 that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

ITEM 1A. RISK FACTORS

Except as noted below, there have been no material changes to the risk factors described in Part I, Item IA of our Annual Report on Form 10-K for the fiscal year ended March 31, 2020, filed with the SEC on June 2, 2020.

We have identified a material weakness in our internal control over financial reporting. If we are unable to remediate this material weakness, or if we identify additional material weaknesses in the future or otherwise fail to maintain an effective system of internal controls, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect our business and stock price.

We have identified a material weakness in our internal control over financial reporting. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of the financial statements will not be prevented or detected on a timely basis.

In connection with the preparation of our financial statements for this Quarterly Report on Form 10-Q, we identified that a material weakness in our internal control over financial reporting existed during the quarter ended, and remained unremediated as of December 31, 2020, relating to our failure to maintain proper controls, processes and procedures over the initial purchase accounting and the continuing fair value accounting associated with the NEPSI Acquisition that were adequately designed, documented and executed to support the accurate and timely reporting of our financial results. Specifically, the modeling assumptions and the calculation performed by our third-party valuation specialist as it relates to fair value accounting for contingent consideration on the purchase accounting for the NEPSI Acquisition included errors resulting in a $1.3 million overstatement in both the  fair value of the earnout payment and the preliminary estimated purchase price paid to NEPSI that we failed to detect, which were reflected in Exhibit 99.3 of our Form 8-K/A filed with the Securities and Exchange Commission (“SEC”) on December 14, 2020. Subsequently, we made post-closing adjustments necessary to properly reflect the fair value of the contingent consideration liability in the financial statements included in this Quarterly Report on Form 10-Q for the period ended December 31, 2020.

Our management, with the oversight of our audit committee, has initiated steps and plans to take additional measures to remediate the underlying causes of the material weakness, which we currently believe will be primarily through the development and implementation of new procedures, policies, and processes, including revising precision level of management review controls and gaining additional assurance regarding timely completion of our outside service providers’ quality control procedures. Although we plan to complete implementing the remediation plan as quickly as possible, we cannot at this time estimate how long it will take, and our initiatives may not prove to be successful in remediating this material weakness. If our remedial measures are insufficient to address the material weakness, or if additional material weaknesses or significant deficiencies in our internal control over financial reporting are discovered or occur in the future, our consolidated financial statements may contain material misstatements and we could be required to restate our financial results. In addition, if we are unable to successfully remediate this material weakness and if we are unable to produce accurate and timely financial statements, our stock price may be adversely affected and we may be unable to maintain compliance with applicable stock exchange listing requirements.

ITEM 2. UNREGISTERED SALES OF EQUITY SECURITIES AND USE OF PROCEEDS

The Company’s stock repurchase activity during the three months ended December 31, 2020 was as follows:

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 

December 31, 2020

and 

2019

and the financial position at

December 31, 2020

; 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, 2020

, and notes thereto, included in the Company's Annual Report on Form

10

-K for the year ended 

March 31, 2020

filed with the SEC on

June 2, 2020.

Liquidity

The Company has historically experienced recurring operating losses and as of

December 31, 2020

, the Company had an accumulated deficit of $

993.7

million. In addition, the Company has historically experienced recurring negative operating cash flows.  At

December 31, 2020

, the Company had cash, cash equivalents, and marketable securities of $

78.1

million. Marketable securities include certificate of deposits with maturities between

three

and

nine

months.  Cash used in operations for the 

nine

months ended 

December 31, 2020

was $

4.9

million.

In

December 2015,

the Company entered into a set of strategic agreements valued at approximately

$210.0

million with Inox Wind Ltd. (“Inox” or “Inox Wind”), which includes a multi-year supply contract pursuant to which the Company will supply electrical control systems ("ECS") to Inox and a license agreement allowing Inox to manufacture a limited number of ECS. After Inox purchases the specified number of ECS required under the terms of the supply contract, Inox agreed that the Company will continue as Inox's preferred supplier and Inox will be required to purchase from the Company a majority of its ECS requirements for an additional

three

-year period. Pursuant to these strategic agreements, Inox must forecast future purchase orders of sets of ECS which become firm orders

three

months prior to shipment, and Inox must post letters of credit before the Company will ship such orders. Inox had been delinquent on its obligation to post letters of credit for sets of ECS that Inox forecasted to purchase under the terms of the supply contract.  On

May 29, 2020,

the Company sent written notice to Inox notifying Inox of its default under the supply contract due to Inox's failure to post letters of credit in the amount of

€6.0

million for the payment of ECS that Inox is obligated to purchase under the terms of the supply contract.  If Inox failed to post letters of credit in the amount of

€6.0

million in accordance with the terms of the supply contract within the

ninety

day cure period after receipt of the default notice, then the Company could have terminated the supply contract by providing written notice of such termination to Inox.  On

September 2, 2020,

Inox delivered approved letters of credit in the amount of

€1.3

million for the payment of a portion of the ECS that Inox was obligated to purchase under the terms of the supply contract.  On

September 11, 2020,

the Company notified Inox that due to (i) the Company's business relationship with Inox, and (ii) Inox's delivery of approved letters of credit in the amount of

€1.3

million as described above, the Company gave Inox until

October 5, 2020

to regain compliance with the terms of the supply contract by providing approved letters of credit in the amount of

€4.7

million for payment of the remaining ECS that Inox currently was obligated to purchase under the terms of the supply contract.  On

October 1, 2020,

Inox delivered approved letters of credit for payment of the remaining ECS that Inox was obligated to purchase under the terms of the supply contract and cured the default set forth in the

May 29, 2020

default notice.

On

October 1, 2020 (

the "Acquisition Date"), the Company 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, 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 "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 now a wholly-owned subsidiary of the Company and is operated by its Grid business unit. The purchase price was

$26.0

million in cash and

873,657

 restricted shares of common stock of the Company.  As part of the transaction, 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 in the future.

On

October 22, 2020,

the Company entered into an underwriting agreement with Oppenheimer & Co. Inc., as representative of the several underwriters named therein, relating to the issuance and sale (the “Offering”) of

3,670,000

shares of the Company's common stock at a public offering price of

$15.00

per share. The net proceeds to the Company from the Offering were approximately

$51.5

 million, after deducting underwriting discounts and commissions and offering expenses payable by the Company. The Offering closed on

October 26, 2020.

In addition, the Company had granted the underwriters a

30

-day option to purchase up to an additional

550,500

shares of common stock at the public offering price which was

not

exercised.

In

March 2020,

the World Health Organization declared the disease caused by the novel coronavirus, COVID-

19,

 to be a pandemic. COVID-

19

 has spread throughout the globe, including in the Commonwealth of Massachusetts where the Company's headquarters are located, and in other areas where the Company has business operations. In response to the outbreak, the Company has followed the guidelines of the U.S. Centers for Disease Control and Prevention and applicable state government authorities to protect the health and safety of the Company's employees, families, suppliers, customers and communities. While these existing measures and, COVID-

19

generally, have

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.

While the COVID-

19

pandemic continues to rapidly evolve, the Company continues to assess the impact of the COVID-

19

pandemic to best mitigate risk and continue the operations of the Company's business. The extent to which the outbreak 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, including new information that

may

emerge concerning the severity of the COVID-

19

pandemic and the actions to contain it or treat its impact, among others.  If the Company, its customers or suppliers experience prolonged shutdowns or other business disruptions, the Company's business, liquidity, results of operations and financial condition are likely to be materially adversely affected, and the Company's ability to access the capital markets

may

be limited. 

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

nine

months ended

December 31, 2020

. The Company's liquidity is highly dependent on its ability to increase revenues, including its ability to collect revenues under its agreements with Inox, its ability to control its operating costs, and its ability to raise additional capital, if necessary.  The impact of the COVID-

19

NEPSI Acquisition

Acquisition of NEPSI

As described in Note

1,

Nature of the Business and Operations and Liquidity, on the Acquisition Date, the Company acquired all of the issued and outstanding shares of capital stock of NEPSI and membership interests of Northeast Power Realty, LLC, a New York limited liability company, which holds the real property that serves as NEPSI's headquarters. 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 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 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 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 Acquisition completed by the Company during the

nine

months ended

December 31, 2020

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 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 Accounting Standards Codification ("ASC

606"

) was completed as part of the Acquisition.  See Note

3

 "Revenue Recognition" for further details.  There were

no

leases acquired and the 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

At the Acquisition Date, in addition to the

$26.0

million cash, the Company valued the Company's common stock, using

$14.23

per share, which was the closing price on the day that the Company acquired NEPSI and

$4.0

million of contingent consideration for the earnout liability valued as of the Acquisition Date. Acquisition costs of 

$0.3

 million were recorded in selling, general and administrative ("SG&A") costs for the 

three

and

nine

months ended

December 31, 2020

.

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,

"Warrants and Derivative Liabilities" 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 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

three

and

nine

months periods ended

December 31, 2020

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 Acquisition was assigned to the Company's Grid segment.  Goodwill recognized in the Acquisition is

not

deductible for tax purposes. This purchase price allocation is preliminary and has

not

been finalized as the analysis on the assets and liabilities acquired, primarily the tax related liability 

may

require further adjustments to our purchase accounting that could result in a measurement period adjustment that would impact our reported net assets and goodwill as of

October 1, 2020.

Material changes, if any, to the preliminary allocation summarized above will be reported once the related uncertainties are resolved, but

no

later than

October 1, 2021.

The

$1.7

million of deferred tax liability is primarily related to inventory step up and intangibles.

Notes to Financial Statements

Revenue from Contract with Customer [Text Block]

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 ASC

606,

Revenue from Contracts with Customers

. 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

nine

months ended

December 31, 2020

, 

78

% and 

79

% 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

nine

months ended 

December 31, 2019

,

57%

and

69%,

respectively, of revenue was recognized at the point in time when control transferred to the customer, with the remainder being recognized over time.

Following the Acquisition of NEPSI, the Company evaluated all open NEPSI contracts at the date of the Acquisition against a

five

-step model in accordance with ASC

606

as NEPSI, as a private company, had deferred adopting 

ASC606

 prior to the Acquisition, as permitted.  The Company identified

two

NEPSI revenue streams which are (

1

) the sale of its major components which falls under the equipment and systems product line and (

2

) the sale of spare parts, which falls under the service product line.  Further details on each of these product lines can be found below.  The Company does

not

expect a material impact to its consolidated statements of operations on an ongoing basis resulting from the adoption of the ASC

606

standard for the NEPSI business, and NEPSI revenue streams will follow the existing policies noted below. 

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.  In the

three

and

nine

months ended

December 31, 2020

, the Company recorded $

1.1

million and $

1.8

 million in grant revenue, respectively, which is included in the Company's Grid segment revenue.  In the 

three

and

nine

 months ended

December 31, 2019

, the Company recorded

$3.9

 million and

$5.3

 million in grant revenue, respectively, which is included in the Company's Grid 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 the profit 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 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

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.  

The following tables disaggregate the Company's revenue by product line and by shipment destination:

As of

December 31, 2020

, and

2019

, 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:

	Unbilled Accounts Receivable			Deferred Program Costs			Contract Liabilities
Beginning balance as of March 31, 2020	$	5,711		$	1,631		$	26,142
Increases for costs incurred to fulfill performance obligations		—			6,635			—

Ending balance as of December 31, 2019	$	4,613		$	1,097		$	23,143

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

December 31, 2020

, the Company had outstanding performance obligations on existing contracts under ASC

606

to be recognized in the next

twelve

months of approximately $

51.1

million. There are also approximately $

7.2

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.

Earnings Per Share [Text Block]

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 the

three

and

nine

months ended

December 31, 2020

, 

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

.

Goodwill and Other Intangibles

Goodwill

The guidance under ASC

805

-

30

provides for the recognition of goodwill on the Acquisition Date measured as the excess of the aggregate consideration transferred over the net of the Acquisition Date amounts of net assets acquired and liabilities assumed. The Company's goodwill balance relates to the Acquisition of NEPSI in the current year and ITC in fiscal

2017

and is reported in the Grid business segment.  The fair market value of the contingent consideration included in the total consideration transferred was determined using the Monte Carlo model, and all other consideration transferred was calculated using its observable fair market value. The tangible net assets acquired fair market value was based on observable market fair value. The acquired intangible asset fair value was determined using discounted cash flows under an excess in earnings model or relief in royalty method where appropriate.

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. 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 our Grid business segment goodwill balance:

	Goodwill

Notes to Financial Statements

Fair Value Disclosures [Text Block]

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

nine

months ended

December 31, 2020

.

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 recognized

no

change in the

three

months ended 

December 31, 2020

 and 

$0.2

 million in unrealized losses on marketable securities, which is recorded in other income (expense), net, for the

nine

 months ended 

December 31, 2020

 and less than a

$0.1

million gain which was recognized during the

nine

months ended

December 31, 2020

upon the sale of

one

of the certificates of deposit.  The Company did

not

recognize any gains or losses on marketable securities in the

three

and

nine

months ended

December 31, 2019

. 

 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 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 Acquisition Date. See Note

13,

"Warrants and Derivative Liabilities" and Note

2,

“NEPSI Acquisition” for further discussion. The Company relied on a Monte Carlo method to determine the fair value of the contingent consideration on the 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. 

Warrants

The Company issued the Hudson Warrants in conjunction with an equity offering to Hudson Bay Capital in

November 2014

and issued warrants to purchase

58,823

shares of the Company's common stock in conjunction a Loan and Security Agreement with Hercules Technology Growth Capital, Inc. (“Hercules Warrants”). The Hercules Warrants were exercised on

April 8, 2019. 

The Hudson Warrants were partially exercised on

November 13, 2019

and the remaining unexercised warrants expired on

November 13, 2019. 

As of 

December 31, 2020

, the Company has

no

remaining outstanding warrants.

The Company historically relied on various assumptions in a lattice model to determine the fair value of warrants. The Company had valued the warrants within Level

3

of the valuation hierarchy. See Note

“Warrants and Derivative Liabilities,” for a discussion of the warrants and the valuation assumptions used.

$0.1

million in the

nine

months ended

.

As a result of a difference in book and tax basis related to the intangible assets acquired in the Acquisition (see Note

2,

"NEPSI Acquisition"), the Company recorded a deferred tax liability of

$1.7

million. As a result, the Company was able to benefit from additional deferred tax assets and therefore released a corresponding valuation allowance of 

$1.7

 million during the 

three

and

nine

 months ended 

December 31, 2020

.  The purchase price allocation is preliminary and has

not

been finalized as the analysis on the assets and liabilities acquired, primarily the tax related liability,

may

require further adjustments to the Company's purchase accounting that could result in measurement period adjustments that would impact the Company's reported net assets and goodwill as of

October 1, 2020.

Material changes, if any, to the preliminary allocation summarized in Note

2,

"NEPSI Acquisition" will be reported once the related uncertainties are resolved, but

no

later than

October 1, 2021.  

Goodwill recognized in the Acquisition is

not

deductible for tax purposes.

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 

nine

months ended 

December 31, 2020

and did

not

have any gross unrecognized tax benefits as of

Contingent Consideration

The Company evaluated the Acquisition earnout payment set forth in the Stock Purchase Agreement (see Note

2.7

 million resulting from the increase in the fair value of the contingent consideration in both the 

three

and

nine

 months ended 

December 31, 2020

Warrants

The Company accounted for its warrants as liabilities due to certain adjustment provisions within the instruments, which required that they be recorded at fair value. The warrants were subject to revaluation at each balance sheet date and any change in fair value was recorded as a change in fair value of warrants until the earlier of its expiration or its exercise at which time the warrant liability was reclassified to equity. The Company calculated the fair value of the warrants utilizing an integrated lattice model. See Note

no

remaining outstanding warrants.

Hercules Warrants

On

the Company entered into a

second

amendment to the Loan and Security Agreement with Hercules (the "Hercules Second Amendment"). In conjunction with the Hercules Second Amendment, the Company issued the Hercules Warrant which replaced the First Warrant and the Second Warrant.  The Hercules Warrant was exercisable at any time after its issuance at an exercise price of

$7.85

per share, subject to certain price-based and other anti-dilution adjustments, including the equity offering in

May 2017,

the acquisition of Infinia Technology Corporation ("ITC") with common stock in

September 2017

and sales of common stock under the ATM entered into in

January 2017.  

This warrant had a fair value of

On

the Company adopted ASU

2016

-

02,

Leases (Topic

842

)

("ASC

842"

), using the modified retrospective approach. The Company elected the package of practical expedients available in the standard and as a result, did

not

reassess the lease classification of existing contracts or leases or the initial direct costs associated with existing leases. The Company did

not

elect the hindsight practical expedient and evaluated lease terms for existing leases. The Company has also elected the practical expedient to

not

separate lease components and non-lease components and will account for the leases as a single lease component for all classes of 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. 

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.

The Company did

not

identify any leases that are classified as financing leases.

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

December 31, 2020

, and 

March 31, 2020

, the Company had $

5.6

million of restricted cash included in long-term assets and $

0.6

million of restricted cash included in current assets, respectively. 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 the Subcontract Agreement with ComEd.  These deposits are held in interest bearing accounts.

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 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.

The operating results for the

two

business segments are as follows (in thousands):

	Three Months Ended December 31,				Nine Months Ended December 31,

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 primarily of loss on contingent consideration of

$2.7

 million in both the 

three

and

nine

months ended

December 31, 2020

. Additionally, unallocated corporate expenses consist of stock-based compensation expense of $

0.8

million and

million in the

three

months ended

and

2019
