4. 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. For its customer contracts, the Company identifies the performance obligations, determines the transaction price, allocates the contract transaction price to the performance obligations, and recognizes the revenue when (or as) control of goods or services is transferred to the customer. For the fiscal year ended  March 31, 2026, 89% of revenue was recognized at the point in time when control transferred to the customer, with the remainder being recognized over time. For the fiscal year ended  March 31, 2025, 88% of revenue was recognized at the point in time when control transferred to the customer, with the remainder being recognized over time. For the fiscal year ended  March 31, 2024, 80% of revenue was recognized at the point in time when control transferred to the customer, with the remainder being recognized over time. 

 

In the Company's product sales, 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. For the fiscal year ended March 31, 2026, 93% of revenue was recognized related to the sales of product, with the remainder being recognized based on the performance of services. For the fiscal year ended March 31, 2025, 94% of revenue was recognized related to the sales of product, with the remainder being recognized based on the performance of services. For the fiscal year ended March 31, 2024, 92% of revenue was recognized related to the sales of product, with the remainder being recognized on the performance of services. 

 

Included in the Company's performance of services, there are several different types of transactions and each begins with a contract with a customer that summarizes each product sold to a customer, which typically represents distinct performance obligations. Included in the business segment line there are technology development transactions that are primarily for activities that have no alternative use and for which a profit can be expected throughout the life of the contract. In these cases, the revenue is recognized over time, but in the instances where the profit cannot be assured throughout the entire contract then the revenue is recognized at a point in time. Each contract's transaction price is allocated to each distinct performance obligation using the respective standalone selling price which is determined primarily using the cost plus expected margin approach. The ongoing service transactions are for service contracts that provide benefit to the customer simultaneously as the Company performs its obligations, and therefore this revenue is recognized ratably over time throughout the effective period of these contracts. The transaction prices on these contracts are allocated based on an adjusted market approach which is re-assessed annually for reasonableness. The field service transactions include contracts for delivery of goods and completion of services made at the customer's requests, which are not deemed satisfied until the work has been completed and/or the requested goods have been delivered, so all of this revenue is recognized at the point in time when the control changes, and at allocated prices based on the adjusted market approach driven by standard price lists. The royalty transactions are related to certain contract terms on transactions in the Company's equipment and systems product line based on activity as specified in the contracts. The transaction prices of these agreements are calculated based on an adjusted market approach as specified in the contract. The Company reports royalty revenue for usage-based royalties when the sales have occurred. In circumstances when collectability is not assured and a contract does not exist under ASC 606, revenue is deferred until a non-refundable payment has been received for substantially all the amount that is due and there are no further remaining performance obligations.

 

The Company's service contracts can include a purchase order from a customer for specific goods in which each item is a distinct performance obligation satisfied at a point in time at which control of the goods is transferred to the customer. This transfer occurs based on the contracted delivery terms or when the requested service work has been completed. The transaction price for these goods is allocated based on the adjusted market approach considering similar transactions under similar circumstances. Service contracts are also derived from ongoing maintenance contracts and extended service-type warranty contracts. In these transactions, the Company is contracted to provide an ongoing service over a specified period of time. As the customer is consuming the benefits as the service is being provided the revenue is recognized over time ratably.

 

The Company’s policy is not to accept volume discounts, product returns, or rebates and allowances within its contracts. In the event a contract was approved with any of these terms, it would be evaluated for variable consideration, estimated and recorded as a reduction of revenue in the same period the related product revenue was recorded.

 

The Company provides assurance-type warranties on all product sales for a term of typically one to three years, and extended service-type warranties are available for purchase 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. As of March 31, 2026 and 2025, the Company's capitalized incremental contract costs were not material. The Company has elected not to adjust the promised amount of consideration for the effects of a significant financing component if the period of financing is twelve months or less. The Company has elected to recognize revenue based on the as invoiced practical expedient if there is a right to consideration from a customer in an amount that corresponds directly with the value of the Company's performance.

 

The Company’s contracts with customers do not typically include extended payment terms and may include milestone billing over the life of the contract. Payment terms vary by contract type and type of customer and generally range from 30 to 60 days from delivery.

 

Following the Comtrafo Acquisition, the Company re-assessed the disaggregated revenue disclosure and determined that segment revenue by product line is no longer a meaningful disclosure. Driven by the change in the overall business landscape following the Comtrafo Acquisition, the Company has determined an increased breakout of segment revenue by region provides more meaningful insight to our overall financial position.

As of  March 31, 2026 and March 31, 2025, 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 7, “Accounts Receivable” and Note 8, “Inventory” for a reconciliation to the consolidated balance sheets) and "Contract liabilities", which are included in the current portion and long term portion of “Deferred revenue” in the Company’s consolidated balance sheets, are as follows (in thousands):

The Company’s remaining performance obligations represent the unrecognized revenue value of the Company’s contractual commitments. The Company’s performance obligations may vary significantly each reporting period based on the timing of major new contractual commitments. As of March 31, 2026, the Company had outstanding performance obligations on existing contracts under ASC 606 to be recognized in the next twelve months of approximately $282.4 million. There are also approximately $97.1 million of outstanding performance obligations to be recognized over a period of thirteen to sixty months. The remaining performance obligations are subject to customer actions and therefore the timing of revenue recognition cannot be reasonably estimated.

About Revenue Disclosures

Revenue disclosures under ASC 606 explain how a company identifies performance obligations, allocates transaction prices, and determines when revenue is recognized. This section is essential for understanding whether reported revenue reflects genuine economic activity or aggressive accounting choices. Analysts examine the mix of point-in-time versus over-time recognition, which directly affects revenue timing and comparability.

Key signals: rising contract liabilities (deferred revenue) suggest strong future revenue visibility, while declining contract assets may indicate slowing project milestones. Watch for variable consideration estimates — rebates, returns, and performance bonuses that require management judgment. Significant changes in disaggregated revenue by geography or product line can reveal shifting business mix before it appears in headline numbers. Compare revenue growth against contract liability growth to assess sustainability, and scrutinize any changes in the timing of recognition that coincide with earnings pressure.
