Organization and Significant Accounting Policies |
Basis of Presentation | Basis of Presentation ​ The accompanying unaudited consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States (“U.S. GAAP”) for interim financial information and with the instructions of Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all of the information and footnotes required by U.S. GAAP for complete financial statements. In the opinion of management, all adjustments, consisting only of normal recurring adjustments necessary for a fair presentation with respect to the interim financial statements have been included. The results of operations for the three and nine months ended January 30, 2021 are not necessarily indicative of the results for the full year ending April 30, 2021. For further information, refer to the consolidated financial statements and footnotes thereto for the year ended April 30, 2020, included in the Company’s Annual Report on Form 10-K. ​ The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions, including estimates of anticipated contract costs and revenue utilized in the revenue recognition process, that affect the reported amounts in the consolidated financial statements and accompanying notes. Actual results could differ from those estimates. ​ The Company’s consolidated financial statements include the assets, liabilities and operating results of wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated. ​ In December 2017, the Company and SoftBank Corp. (“SoftBank”) formed a joint venture, HAPSMobile Inc. (“HAPSMobile”). As the Company has the ability to exercise significant influence over the operating and financial policies of HAPSMobile, the Company’s investment has been accounted for as an equity method investment. The Company has presented its proportion of HAPSMobile’s net loss in equity method investment loss, net of tax in the consolidated statements of operations. During the nine months ended January 25, 2021, the Company recorded its proportion of a loss for HAPSMobile’s impairment of its investment in Loon LLC in the amount of $8,363,000. The Company’s investment has been written down to zero. Refer to Note 6—Equity Method Investments for further details. ​ On June 10, 2019, the Company purchased 100% of the issued and outstanding member units of Pulse Aerospace, LLC (“Pulse”) pursuant to the terms of a Unit Purchase Agreement (the “Pulse Purchase Agreement”). The assets, liabilities and operating results of Pulse have been included in the Company’s consolidated financial statements. On February 12, 2021, the Company dissolved its wholly-owned subsidiary, Pulse Aerospace, LLC, the results of which were not material to the consolidated financial statements as the Company has integrated the assets and operations. Refer to Note 17—Business Acquisitions for further details. ​ During the nine months ended January 25, 2020, the Company dissolved its wholly-owned subsidiary, Skytower, Inc., the results of which were not material to the consolidated financial statements.
Recently Adopted Accounting Standards | Recently Adopted Accounting Standards ​ Effective May 1, 2020, the Company adopted Accounting Standards Update (“ASU”) 2016-13, Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments, along with several additional clarification ASU’s issued during 2018 and 2019, collectively “CECL”. CECL requires the reporting entity to estimate expected credit losses over the life of a financial asset. CECL requires the credit loss to be recognized upon initial recognition of the financial asset. ASU 2016-13 requires the entity to adopt CECL using the modified retrospective transition approach through a cumulative-effect adjustment to the opening balance of retained earnings in the period of adoption. As part of the assessment of the adequacy of the Company’s allowances for credit losses, the Company considered a number of factors including, but not limited to, customer credit ratings, age of receivables, and expected loss rates. However, the adoption of CECL did not have a material impact to retained earnings for the Company. ​ Effective May 1, 2020, the Company adopted ASU 2018-15, “Intangibles—Goodwill and Other— Internal-Use Software (Subtopic 350-40) Customer’s Accounting for Implementation Costs Incurred in a Cloud Computing Arrangement That Is a Service Contract” (“ASU 2018-15”). ASU 2018-15 provides guidance on the treatment of accounting for fees paid by a customer in a cloud computing arrangement. This guidance includes the requirements for capitalizing implementation costs incurred in a hosting arrangement. The Company adopted ASU 2018-15 using the prospective method, applying the new guidance to all implementation costs incurred after adoption. The adoption of ASU 2018-15 did not have an impact on the Company’s consolidated financial statements. ​
Segments | Segments ​ Operating segments are defined as components of an enterprise about which separate financial information is available that is evaluated regularly by the Chief Operating Decision Maker (“CODM”) in deciding how to allocate resources and in assessing performance. The Company’s CODM, who is the Chief Executive Officer, makes operating decisions, assesses performance and makes resource allocation decisions, including the focus of research and development (“R&D”), on a consolidated basis for the Company’s continuing operations. Accordingly, the Company operates its business as a single reportable segment.
Investments | Investments ​ The Company’s investments are accounted for as available-for-sale and are reported at fair value. Unrealized gains and losses are excluded from earnings and reported as a separate component of stockholders’ equity, net of deferred income taxes for available-for-sale investments. Gains and losses realized on the disposition of investment securities are determined on the specific identification basis and credited or charged to income. Management determines the appropriate classification of securities at the time of purchase and reevaluates such designation as of each balance sheet date. ​ Investments are considered to be impaired if the fair value of the investment is less than its amortized cost basis. On a quarterly basis, the Company considers available quantitative and qualitative evidence in evaluating potential impairment of its investments. If the cost of an investment exceeds its fair value, the Company evaluates if the decline in fair value resulted from a credit loss or other factors. The Company considers factors such as general market conditions and potential adverse conditions related to the financial health of the issuer based on rating agency actions. Impairments relating to credit losses are recorded in earnings through an allowance for credit losses. The allowance is limited by the amount that the fair value is less than the amortized cost basis. Impairments not related to credit losses are recorded through other comprehensive income, net of applicable taxes.
Fair Values of Financial Instruments | Fair Values of Financial Instruments ​ Fair values of cash and cash equivalents, accounts receivable, unbilled receivables and retentions, and accounts payable approximate cost due to the short period of time to maturity.
Government Contracts | Government Contracts ​ Payments to the Company on government CPFF or T&M contracts are based on provisional, or estimated indirect rates, which are subject to an annual audit by the Defense Contract Audit Agency (“DCAA”). The cost audits result in the negotiation and determination of the final indirect cost rates that the Company may use for the period(s) audited. The final rates, if different from the provisional rates, may create an additional receivable or liability for the Company for CPFF and T&M contracts. ​ For example, during the course of its audits, the DCAA may question the Company’s incurred costs, and if the DCAA believes the Company has accounted for such costs in a manner inconsistent with the requirements under Federal Acquisition Regulations, the DCAA auditor may recommend to the Company’s administrative contracting officer to disallow such costs. Historically, the Company has not experienced material disallowed costs as a result of government audits. However, the Company can provide no assurance that the DCAA or other government audits will not result in material disallowances for incurred costs in the future. ​ The Company’s revenue recognition policy calls for revenue recognized on all cost reimbursable government contracts to be recorded at actual rates unless collectability is not reasonably assured. During the fiscal year ended April 30, 2020, the Company settled rates for its incurred cost claims with the DCAA for fiscal year 2015 for an amount that was not significant. At January 30, 2021 and April 30, 2020, the Company had no reserve for incurred cost claim audits. ​
Earnings (Loss) Per Share | Earnings (Loss) Per Share ​ Basic earnings (loss) per share is computed using the weighted-average number of common shares outstanding, excluding shares of unvested restricted stock. ​ The reconciliation of basic to diluted shares is as follows: ​
​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | ​ | Three Months Ended | ​ | ​ | Nine Months Ended |
​ |  | January 30, 2021 |  | January 25, 2020 |  | January 30, 2021 |  | January 25, 2020 |
Denominator for basic earnings (loss) per share: | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Weighted average common shares | ​ |  | 23,942,782 | ​ |  | 23,821,145 |  | ​ | 23,924,017 |  | ​ | 23,790,788 | ​
Dilutive effect of employee stock options, restricted stock and restricted stock units | ​ |  | 318,092 | ​ |  | — |  | ​ | 292,354 |  | ​ | 285,407 | ​
Denominator for diluted earnings (loss) per share | ​ | ​ | 24,260,874 | ​ | ​ | 23,821,145 | ​ | ​ | 24,216,371 | ​ | ​ | 24,076,195 | ​
​ Potentially dilutive shares not included in the computation of diluted weighted-average common shares because their effect would have been anti-dilutive were 0 and 24 for the three and nine months ended January 30, 2021. Due to the net loss for the three months ended January 25, 2020, no shares reserved for issuance upon exercise of stock options or shares of unvested restricted stock were included in the computation of diluted loss per share as their inclusion would have been anti-dilutive. Potentially dilutive shares not included in the computation of diluted weighted-average common shares because their effect would have been anti-dilutive were 287,408 and 3,076 for the three and nine months ended January 25, 2020, respectively.
Recently Issued Accounting Standards | Recently Issued Accounting Standards ​ In December 2019, the FASB issued ASU 2019-12, Simplifying the Accounting for Income Taxes (Topic 740). This ASU simplifies the accounting for income taxes by removing certain exceptions to the general principles in Topic 740. The guidance is effective for fiscal years beginning after December 15, 2020 and interim periods therein, with early adoption permitted. The adoption method is dependent on the specific amendment included in this update as certain amendments require retrospective adoption, modified retrospective adoption, an option of retrospective or modified retrospective, and prospective adoption. The Company is evaluating the potential impact of this adoption on its consolidated financial statements. ​ In January 2020, the FASB issued ASU 2020-01, Clarifying the Interactions between Topic 321, Topic 323, and Topic 815 (Topic 321, Topic 323, and Topic 815). This ASU clarifies accounting certain topics impacted by Topic 321 Investments—Equity Securities. These topics include measuring equity securities using the measurement alternative, how the measurement alternative should be applied to equity method accounting, and certain forward contracts and purchased options which would be accounted for under the equity method of accounting upon settlement or exercise. The guidance is effective for fiscal years beginning after December 15, 2020 and interim periods therein, with early adoption permitted. The amendments should be adopted prospectively. The Company is evaluating the potential impact of this adoption on its consolidated financial statements.
