Summary of Significant Accounting Policies

Note 2 – Summary of Significant Accounting Policies

Information regarding our significant accounting policies is contained in Note 2, “Summary of Significant Accounting Policies,” of the consolidated financial statements in the Amended Form 10-K, as filed with the SEC on April 24, 2024.

Revenue Recognition

Revenue recognized from services provided under our customer contracts is disaggregated into manufacturing and process development revenue streams.

Manufacturing revenue

Manufacturing revenue generally represents revenue from the manufacturing of customer products recognized over time utilizing an input method that compares the cost of cumulative work-in-process to date to the most current estimates for the entire cost of the performance obligation. Under a manufacturing contract, a quantity of manufacturing runs are ordered at a specified scale with prescribed dates, where the product is manufactured according to the customer’s specifications and typically includes only one performance obligation. Each manufacturing run represents a distinct service that is sold separately and has stand-alone value to the customer. The products are manufactured exclusively for a specific customer and have no alternative use. The customer retains control of its product during the entire manufacturing process and can make changes to the process or specifications at its request. Under these agreements, we are entitled to consideration for progress to date that includes an element of profit margin.

Process development revenue

Process development revenue generally represents revenue from services associated with the custom development of a manufacturing process and analytical methods for a customer’s product. Process development revenue is recognized over time utilizing an input method that compares the cost of cumulative work-in-process to date to the most current estimates for the entire cost of the performance obligation. Under a process development contract, the customer owns the product details and process, which has no alternative use. These process development projects are customized to each customer to meet its specifications and typically includes only one performance obligation. Each process represents a distinct service that is sold separately and has stand-alone value to the customer. The customer also retains control of its product as the product is being created or enhanced by our services and can make changes to its process or specifications upon request. Under these agreements, we are entitled to consideration for progress to date that includes an element of profit margin.

The following table summarizes our revenue streams (in thousands):

	Three Months Ended October 31,				Six Months Ended October 31,
	2023		2022		2023		2022
Manufacturing revenues	$	20,128	$	27,614	$	53,548	$	59,095
Process development revenues		5,267		7,143		9,573		12,354
Total revenues	$	25,395	$	34,757	$	63,121	$	71,449

The timing of revenue recognition, billings and cash collections results in billed accounts receivable, contract assets (unbilled receivables), and contract liabilities (customer deposits and deferred revenue). Contract assets are recorded when our right to consideration is conditioned on something other than the passage of time. Contract assets are reclassified to accounts receivable on the consolidated balance sheet when our rights become unconditional. Contract liabilities represent customer deposits and deferred revenue billed and/or received in advance of our fulfillment of performance obligations. Contract liabilities convert to revenue as we perform our obligations under the contract.

During the three and six months ended October 31, 2023, we recognized revenue of $4.0 million and $20.8 million, respectively, for which the contract liability was recorded in a prior period.

During the three and six months ended October 31, 2022, we recognized revenue of $8.3 million and $26.9 million, respectively, for which the contract liability was recorded in a prior period.

The transaction price for services provided under our customer contracts reflects our best estimates of the amount of consideration to which we are entitled in exchange for providing goods and services to our customers. For contracts with multiple performance obligations, we allocate transaction price to each performance obligation identified in a contract on a relative standalone selling price basis. For contracts in which we receive noncash consideration, such as in the form of a customer’s equity securities, we utilize the quoted market price for such noncash consideration to determine the transaction price. We generally determine relative standalone selling prices based on the price observed in the customer contract for each distinct performance obligation. If observable standalone selling prices are not available, we may estimate the applicable standalone selling price based on the pricing of other comparable services or on a price that we believe the market is willing to pay for the applicable service.

In determining the transaction price, we also considered the different sources of variable consideration including, but not limited to, discounts, credits, refunds, price concessions or other similar items. We have included in the transaction price some or all of an amount of variable consideration, utilizing the most likely method, only to the extent that it is probable that a significant reversal in the amount of cumulative revenue recognized will not occur when the uncertainty associated with the variable consideration is subsequently resolved. The actual amount of consideration ultimately received may differ.

In addition, our customer contracts generally include provisions entitling us to a cancellation or postponement fee when a customer cancels or postpones its commitments prior to our initiation of services, therefore not utilizing their reserved capacity. The determination of such cancellation and postponement fees are based on the terms stated in the related customer contract but are generally considered substantive for accounting purposes and create an enforceable right and obligation due to us when the cancellation or postponement occurs. Accordingly, we recognize such fees, subject to variable consideration, as revenue upon the cancellation or postponement date utilizing the most likely method.

Management may be required to exercise judgement in estimating revenue to be recognized. Judgement is required in identifying performance obligations, estimating the transaction price, estimating the stand-alone selling prices of identified performance obligations, estimating variable consideration, and estimating the progress towards the satisfaction of performance obligations. If actual results in the future vary from our estimates, the estimates will be adjusted, which will affect revenues in the period that such variances become known.

During the three and six months ended October 31, 2023, changes in estimates for variable consideration resulted in a decrease in revenues of $1.8 million and $3.2 million, respectively. The changes in estimates for variable consideration can be attributed to an insolvent customer combined with consideration under a contract where uncertainties have been resolved. There were no material adjustments in estimates for variable consideration for the three and six months ended October 31, 2022.

We apply the practical expedient available under ASC 606 that permits us not to disclose the value of unsatisfied performance obligations for contracts with an original expected length of one year or less. As of October 31, 2023, we do not have any unsatisfied performance obligations for contracts greater than one year.

Costs incurred to obtain a contract are not material. These costs are generally employee sales commissions, which are expensed as incurred and included in selling, general and administrative expense in the unaudited condensed consolidated statements of income (loss) and comprehensive income (loss).

Restricted Cash

Under the terms of an operating lease related to one of our non-manufacturing facilities that was primarily utilized for office space (Note 4), we were required to maintain a letter of credit as collateral during the term of the lease. As of October 31, 2023, no restricted cash remained pledged as collateral for the letter of credit as the associated operating lease has expired. As of April 30, 2023, restricted cash of $0.4 million was pledged as collateral under the letter of credit.

The following table provides a reconciliation of cash, cash equivalents and restricted cash reported within the unaudited condensed consolidated balance sheets that sum to the total of the same amounts shown in the unaudited condensed consolidated statements of cash flows (in thousands):

	October 31, 2023		April 30, 2023		October 31, 2022		April 30, 2022
Cash and cash equivalents	$	31,424	$	38,542	$	77,292	$	126,166
Restricted cash		–		350		350		350
Total cash, cash equivalents and restricted cash	$	31,424	$	38,892	$	77,642	$	126,516

Accounts Receivable, Net

Accounts receivable is primarily comprised of amounts owed to us for services provided under our customer contracts and are recorded at the invoiced amount net of an allowance for doubtful accounts, if necessary. We apply judgement in assessing the ultimate realization of our receivables, that includes an assessment of expected credit losses, and we estimate our allowance for doubtful accounts based on various factors, including our historical collection experience, aging of our customer receivable balances, current and future economic market conditions, and the financial condition of our customers.

Based on our analysis of our accounts receivable balance as of October 31, 2023 and April 30, 2023, we determined an allowance for doubtful accounts of $1.6 million and $0.5 million, respectively, was deemed necessary.

Inventory

Inventory consists of raw materials inventory and is valued at the lower of cost, determined by the first-in, first-out method, or net realizable value. We periodically review raw materials inventory for potential impairment and adjust inventory to its net realizable value based on the estimate of future use and reduce the carrying value of inventory as deemed necessary.

Property and Equipment

Property and equipment is recorded at cost, less accumulated depreciation and amortization. Depreciation and amortization are computed using the straight-line method over the estimated useful lives of the related asset, which are generally as follows:

Description	Estimated Useful Life
Leasehold improvements	Shorter of estimated useful life or lease term
Laboratory and manufacturing equipment	5 – 15 years
Computer equipment and software	3 – 5 years
Furniture, fixtures and office equipment	5 – 10 years

Costs for property and equipment not yet placed into service have been capitalized as construction-in-progress. These costs are primarily related to equipment and leasehold improvements associated with our manufacturing facilities and will be depreciated in accordance with the above guidelines once placed into service. Interest costs incurred during construction of major capital projects are capitalized as construction-in-progress until the underlying asset is ready for its intended use, at which point the interest costs are amortized as depreciation expense over the life of the underlying asset. Interest capitalized as construction-in-progress for the three and six months ended October 31, 2023 was $0.2 million and $0.3 million, respectively. Interest capitalized as construction-in-progress was de minimis for the three and six months ended October 31, 2022. All of our property and equipment are located in the United States. Property and equipment consist of the following (in thousands):

	October 31, 2023			April 30, 2023
		(as restated)			(as restated)
Leasehold improvements	$	101,572		$	97,514
Laboratory and manufacturing equipment		43,336			35,501
Computer equipment and software		5,170			5,028
Furniture, fixtures and office equipment		1,910			1,681
Construction-in-progress		71,562			68,414
Total property and equipment, gross		222,350			208,138
Less: accumulated depreciation and amortization		(35,676	)		(30,368	)
Total property and equipment, net	$	187,874		$	177,770

Depreciation and amortization expense for the three and six months ended October 31, 2023 was $2.8 million and $5.4 million, respectively.

Depreciation and amortization expense for the three and six months ended October 31, 2022 was $1.8 million and $3.4 million, respectively.

Leases

We determine if an arrangement is or contains a lease at inception. Our operating leases with a term greater than one year are included in operating lease right-of-use (“ROU”) assets, operating lease liabilities and operating lease liabilities, less current portion in our consolidated balance sheets. ROU assets represent our right to use an underlying asset during the lease term and lease liabilities represent our obligation to make lease payments arising from the lease. Operating lease ROU assets and liabilities are recognized at the lease commencement date, based on the present value of lease payments over the lease term. In determining the net present value of lease payments, we use our incremental borrowing rate which represents an estimated rate of interest that we would have to pay to borrow equivalent funds on a collateralized basis at the lease commencement date.

Our operating leases may include options to extend the lease which are included in the lease term when it is reasonably certain that we will exercise a renewal option. Operating lease expense is recognized on a straight-line basis over the expected lease term.

Our finance leases with a term greater than one year are included as assets within property and equipment, net and a lease liability equal to the present value of the minimum lease payments is included in other current liabilities and finance lease liabilities, less current portion in our consolidated balance sheets. The present value of the finance lease payments is calculated using the implicit interest rate in the lease. Finance lease ROU assets are amortized on a straight-line basis over the expected useful life of the asset and the carrying amount of the lease liability is adjusted to reflect interest, which is recorded as interest expense.

Leases with an initial term of 12 months or less are not recorded on our consolidated balance sheets and lease expense for these short-term leases is recognized on a straight-line basis over the lease term. We have also elected the practical expedient to not separate lease components from non-lease components.

Impairment

Long-lived assets are reviewed for impairment in accordance with authoritative guidance for impairment or disposal of long-lived assets. Long-lived assets are reviewed for events or changes in circumstances that indicate that their carrying value may not be recoverable. If such events or changes in circumstances arise, we compare the carrying amount of the long-lived assets to the estimated future undiscounted cash flows expected to be generated by the long-lived assets. If the long-lived assets are determined to be impaired, any excess of the carrying value of the long-lived assets over its estimated fair value is recognized as an impairment loss. For the six months ended October 31, 2023 and 2022, there were no indicators of impairment of the value of our long-lived assets and no cumulative impairment losses were recognized as of October 31, 2023.

Stock-Based Compensation

We account for stock options, restricted stock units, performance stock units and other stock-based awards granted under our equity compensation plans in accordance with the authoritative guidance of ASC 718, Compensation – Stock Compensation. The estimated fair value of stock options granted to employees in exchange for services is measured at the grant date, using a fair value-based method, such as a Black-Scholes option valuation model, and is recognized as an expense on a straight-line basis over the requisite service periods. The fair value of restricted stock units and performance stock units is measured at the grant date based on the closing market price of our common stock on the date of grant. For restricted stock units, the fair value is recognized as an expense on a straight-line basis over the requisite service periods. For performance stock units, which are subject to performance conditions, the fair value is recognized as expense on a straight-line basis over the requisite service periods when the achievement of such performance condition is determined to be probable. If a performance condition is not determined to be probable or is not met, no stock-based compensation expense is recognized, and any previously recognized expense is reversed. Forfeitures are recognized as a reduction of stock-based compensation expense as they occur.

Debt Issuance Costs

Debt issuance costs related to convertible senior notes are recorded as a deduction that is netted against the principal value of the debt and are amortized to interest expense using the effective interest method over the contractual term of the debt (Note 3).

Debt issuance costs related to the revolving credit facility are included in prepaid expenses and other current assets in the consolidated balance sheet and are amortized to interest expense over the contractual term of the revolving credit facility (Note 3).

Comprehensive Income (Loss)

Comprehensive income (loss) is the change in equity during a period from transactions and other events and circumstances from non-owner sources. Comprehensive income (loss) is equal to our net income (loss) for all periods presented.

Fair Value Measurements

Fair value is defined as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The guidance prioritizes the inputs used in measuring fair value into the following hierarchy:

· Level 1 – Observable inputs, such as unadjusted quoted prices in active markets for identical assets or liabilities.

· Level 2 – Observable inputs other than quoted prices included in Level 1, such as assets or liabilities whose values are based on quoted market prices in markets where trading occurs infrequently or whose values are based on quoted prices of instruments with similar attributes in active markets.

· Level 3 – Unobservable inputs that are supported by little or no market activity and significant to the overall fair value measurement of the assets or liabilities; therefore, requiring the company to develop its own valuation techniques and assumptions.

As of October 31, 2023 and April 30, 2023, our Level 1 financial assets consisted of our cash equivalents invested in money market funds of $21.6 million and $28.7 million, respectively, and our other current assets related to investments in equity securities of $7.5 million and $0, respectively. Our Level 1 financial assets are carried at a fair value based on quoted market prices for identical securities (Level 1 input). We did not have any Level 2 or Level 3 financial assets as of October 31, 2023 and April 30, 2023.

We consider the fair value of our convertible senior notes to be a Level 2 financial liability due to limited trading activity of the convertible senior notes (Note 3). We did not have any other Level 2 or Level 3 financial liabilities as of October 31, 2023 and April 30, 2023.

Recently Adopted Accounting Standard

In June 2016, the Financial Accounting Standards Board (“FASB”) issued ASU No. 2016-13, Financial Instruments – Credit Losses (Topic 326): Measurement of Credit Losses of Financial Instruments (“ASU 2016-13”). The standard amends the impairment model by requiring entities to use a forward-looking approach based on expected losses to estimate credit losses for most financial assets and certain other instruments. We adopted ASU 2016-13 on May 1, 2023, and the adoption of this standard did not have a material impact on our unaudited condensed consolidated financial statements.
