Basis of Presentation

The six month period ended June 30, 2021 (the “Successor 2021 Period”), and the period from February 10, 2020 (inception) to June 30, 2020 (the “Successor Q2 2020 Period”) relate to the activity of Cosmos Intermediate, LLC and its subsidiaries. MIS was identified as the Predecessor through an analysis of various factors, including the size, financial characteristics, ongoing management, and order in which the acquired entities were acquired. The year to date period ended June 21, 2020 (the “Predecessor 2020 Period”) relates to the activity of MIS and its subsidiaries.

The accompanying condensed consolidated financial statements have been prepared in accordance with the United States (“U.S.”) generally accepted accounting principles (“GAAP”) for interim financial statement information. Accordingly, they do not include all of the information and notes required by GAAP for complete financial statements. The year-end condensed consolidated balance sheet data was derived from audited financial statements but does not include all disclosures required by accounting principles generally accepted in the United States of America. In the opinion of management, the condensed consolidated financial statements include all adjustments, consisting of adjustments associated with acquisition accounting and normal recurring adjustments, necessary for the fair statement of such financial statements. All intercompany balances and transactions have been eliminated in consolidation.

The Company’s unaudited interim condensed consolidated financial statements should be read in conjunction with the audited annual consolidated financial statements and related notes for the period ended December 31, 2020. Interim results are not necessarily indicative of the results for a full year.

There have been no significant changes from the significant accounting policies disclosed in Note B of the “Notes to Consolidated Financial Statements” included in the annual consolidated financial statements for the period ended December 31, 2020.

Basis of Presentation

MIS was identified as the Predecessor through an analysis of various factors, including the size, financial characteristics, ongoing management, and order of the acquired entities. As of December 31, 2019 and for the year ended December 31, 2019 (collectively, the “Predecessor 2019 Period”) and the period from January 1, 2020 to June 21, 2020 (the “Predecessor 2020 Period”) relate to the predecessor period for Cosmos and includes all of the accounts of only MIS and its subsidiaries. As of December 31, 2020 and for the period from February 10, 2020 (inception) through December 31, 2020 (collectively, the “Successor 2020 Period”) relate to activity of Cosmos Intermediate, LLC and its subsidiaries. The Successor 2020 Period begins before the Predecessor 2020 Period ends due to the acquisitions that took place prior to the acquisition of MIS.

The Adcole, DSS, MIS, Roccor, and LoadPath acquisitions were accounted for as business combinations in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 805, Business Combinations (“ASC 805”), and the resulting new basis of accounting is reflected in the Successor 2020 Period as of each acquisition date. As a result, financial information of the Predecessor and Successor periods has been prepared under two different bases of accounting and therefore are not comparable.

The consolidated financial statements have been prepared in accordance with the United States (“U.S.”) generally accepted accounting principles (“GAAP”) and all intercompany balances and transactions have been eliminated in consolidation. Amounts presented within tables in the consolidated financial statements and accompanying notes are presented in thousands of U.S. dollars, with the exception of percentages, unit, share, per unit, and per share amounts.

Use of Estimates

The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the dates of the financial statements and the reported amounts of revenues and expenses during the reporting periods.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, actual results could differ from those estimates. Accounting policies subject to estimates include valuation of intangible assets and contingent consideration, revenue recognition, income taxes, and equity-based compensation.

Revenue Recognition

Based on the specific analysis of its contracts, the Company has determined that its contracts are subject to revenue recognition in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). Recognition under the ASC 606 five-step model involves (i) identification of the contract, (ii) identification of performance obligations in the contract, (iii) determination of the transaction price, (iv) allocation of the transaction price to the previously identified performance obligations, and (iv) revenue recognition as the performance obligations are satisfied.

During step one of the five step model, the Company considers whether contracts should be combined or separated, and based on this assessment, the Company combines closely related contracts when all the applicable criteria are met. The combination of two or more contracts requires judgment in determining whether the intent of entering into the contracts was effectively to enter into a single contract, which should be combined to reflect an overall profit rate. Similarly, the Company may separate an arrangement, which may consist of a single contract or group of contracts, with varying rates of profitability, only if the applicable criteria are met. Judgment is involved in determining whether a group of contracts may be combined or separated based on how the arrangement and the related performance criteria were negotiated. The conclusion to combine a group of contracts or separate a contract could change the amount of revenue and gross profit recorded in a given period.

A performance obligation is a promise in a contract to transfer a distinct good or service to the customer. A contract’s transaction price is allocated to each distinct performance obligation and recognized as revenue when the performance obligation is satisfied. The Company’s contracts with customers generally do not include a right of return relative to delivered products. In certain cases, contracts are modified to account for changes in the contract specifications or requirements. In most instances, contract modifications are accounted for as part of the existing contract. Certain contracts with customers have options for the customer to acquire additional goods or services. In most cases the pricing of these options are reflective of the standalone selling price of the good or service. These options do not provide the customer with a material right and are accounted for only when the customer exercises the option to purchase the additional goods or services. If the option on the customer contract was not indicative of the standalone selling price of the good or service, the material right would be accounted for as a separate performance obligation.

The Company’s revenues are derived from the design and sales of components for spacecraft and satellites and the performance of engineering, modeling and simulation services related to spacecraft design and mission execution. Each promised good or service within a contract is accounted for separately under the guidance of ASC 606 if they are distinct. Promised goods or services not

meeting the criteria for being a distinct performance obligation are bundled into a single performance obligation with other goods or services that together meet the criteria for being distinct. The appropriate allocation of the transaction price and recognition of revenue is then applied for the bundled performance obligation. The Company has concluded that its service contracts generally contain a single performance obligation given the interrelated nature of the activities within the context to which the transaction price is assigned and for which revenue is recognized over time.

Once the Company identifies the performance obligations, the Company determines the transaction price, which includes estimating the amount of variable consideration to be included in the transaction price, if any. The Company’s contracts generally do not contain penalties, credits, price concessions, or other types of potential variable consideration. Prices are fixed at contract inception and are not contingent on performance or any other criteria.

The Company engages in long-term contracts for production and service activities and recognizes revenue for performance obligations over time. These long-term contracts involve the design, development, manufacture, or modification of components for spacecraft and satellites. Revenue is recognized over time (versus point in time recognition), as the Company’s performance creates an asset with no alternative use to the Company and the Company has an enforceable right to payment for performance completed to date, and the customer receives the benefit as the Company builds the asset. The Company considers the nature of these contracts and the types of products and services provided when determining the proper accounting for a particular contract. These contracts include both fixed-price and cost reimbursable contracts. The Company’s cost reimbursable contracts typically include cost-plus fixed fee and time and material (“T&M”) contracts.

For long-term contracts, the Company typically recognizes revenue using the input method, using a cost-to-cost measure of progress. The Company believes that this method represents the most faithful depiction of the Company’s performance because it directly measures value transferred to the customer. Contract estimates are based on various assumptions to project the outcome of future events that may span several years. These assumptions include: the amount of time to complete the contract, including the assessment of the nature and complexity of the work to be performed; the cost and availability of materials; the availability of subcontractor services and materials; and the availability and timing of funding from the customer. The Company bears the risk of changes in estimates to complete on a fixed-price contract, which may cause profit levels to vary from period to period. For cost reimbursable contracts, the Company is reimbursed periodically for allowable costs and is paid a portion of the fee based on contract progress. In the limited instances where the Company enters into T&M contracts, revenue recognized reflects the number of direct labor hours expended in the performance of a contract multiplied by the contract billing rate, as well as reimbursement of other direct billable costs. For T&M contracts, the Company recognizes revenue in the amount for which the Company has a right to invoice the customer based on the control transferred to the customer. For over time contracts, the Company recognizes anticipated contract losses as soon as they become known and estimable.

Accounting for long-term contracts requires significant judgment relative to estimating total contract revenues and costs, in particular, assumptions relative to the amount of time to complete the contract, including the assessment of the nature and complexity of the work to be performed. The Company’s estimates are based upon the professional knowledge and experience of its engineers, program managers and other personnel, who review each long-term contract monthly to assess the contract’s schedule, performance, technical matters and estimated cost at completion. Changes in estimates are applied retrospectively and when adjustments in estimated contract costs are identified, such revisions may result in current period adjustments to earnings applicable to performance in prior periods.

On long-term contracts, the portion of the payments retained by the customer is not considered a significant financing component; the Company expects, at contract inception, that the lag period between the transfer of a promised good or service to a customer and when the customer pays for that good or service will not constitute a significant financing component. Many of the Company’s long-term contracts have milestone payments, which align the payment schedule with the progress towards completion on the performance obligation. On some contracts, the Company may be entitled to receive an advance payment, which is not considered a significant financing component because it is used to facilitate inventory demands at the onset of a contract and to safeguard the Company from the failure of the other party to abide by some or all of their obligations under the contract.

Contract Balances

Contract balances result from the timing of revenue recognized, billings and cash collections, and the generation of contract assets and liabilities.

Contract assets represent revenue recognized in excess of amounts invoiced to the customer and the right to payment is not subject to the passage of time. Contract liabilities are presented as deferred revenue on the Company’s consolidated balance sheets and consist of deferred product revenue, billings in excess of revenues, deferred service revenue, and customer advances. Deferred product revenue represents amounts that have been invoiced to customers but are not yet recognizable as revenue because the Company has not satisfied its performance obligations under the contract. Billings in excess of revenues represents milestone billing contracts where the billings of the contract exceed recognized revenues.

Contract asset balances on the Company’s consolidated balance sheets were $4,172 thousand as of December 31, 2020 (Successor), compared to $232 thousand as of December 31, 2019 (Predecessor). The change was primarily driven by contract asset balances as of the Successor 2020 Period including contract asset balances related to Adcole, MIS, DSS, Roccor, and LoadPath, while the Predecessor 2019 Period included contract asset balances related to MIS only.

Contract liability balances included in deferred revenue on the Company’s consolidated balance sheets were $15,665 thousand as of the December 31, 2020 (Successor), compared to $6,316 thousand as of December 31, 2019 (Predecessor). The change was primarily driven by contract liability balances as of the Successor 2020 Period including contract liability balances related to Adcole, MIS, DSS, Roccor, and LoadPath, while the Predecessor 2019 Period included contract liability balances related to MIS only. Revenue recognized in the Successor 2020 and the Predecessor 2020 Period that was included in the contract liability balance as of December 31, 2019 (Predecessor) was $1,792 thousand and $4,551 thousand, respectively.

Remaining Performance Obligations

The Company includes in its computation of remaining performance obligations customer orders for which it has accepted signed sales orders. The definition of remaining performance obligations excludes those contracts accounted for under the “right to invoice” practical expedient. As of December 31, 2020 (Successor), the aggregate amount of the transaction price allocated to remaining performance obligations was $122,019 thousand. The Company expects to recognize approximately 60% of its remaining performance obligations as revenue within the next 12 months and the balance thereafter.

Fair Value of Financial Instruments

The Company measures certain financial assets and liabilities, including contingent consideration, at fair value. ASC 820, Fair Value Measurement and Disclosures (“ASC 820”), specifies a hierarchy of valuation techniques based on whether the inputs to those valuation techniques are observable or unobservable. Observable inputs reflect market data obtained from independent sources, while unobservable inputs reflect the Company’s market assumptions. These two types of inputs have created the following fair-value hierarchy:

Level 1—Quoted prices for identical instruments in active markets;

Level 2—Quoted prices for similar instruments in active markets, quoted prices for identical or similar instruments in markets that are not active, and model-derived valuations in which all significant inputs and significant value drivers are observable in active markets; and

Level 3—Valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

Inventory

Inventory is stated at the lower of cost or net realizable value. Cost is calculated on a first-in, first-out (“FIFO”) basis. Inventory may consist of raw materials, work-in-process, and finished goods. Net realizable value is the estimated selling price in the ordinary course of business, less the estimated costs of completion and selling expense. Inventory is impaired when it is probable that inventory values exceed their net realizable value. Changes in these estimates are included in cost of sales in the consolidated statements of operations.

Goodwill and Indefinite-Lived Assets

Goodwill is the amount by which the purchase price exceeded the fair value of the net identifiable assets acquired and liabilities assumed in a business combination on the date of acquisition (see Note G). Goodwill is assessed for impairment at least annually as of October 1, on a reporting unit basis, or when events and circumstances occur indicating that the recorded goodwill may be impaired. The Company assesses impairment first on a qualitative basis to determine if a quantitative assessment is necessary. In circumstances where our qualitative analysis indicates that the fair value of a reporting unit does not exceed its carrying value, the goodwill impairment loss is measured as the amount by which a reporting unit’s carrying amount exceeds its fair value, not to exceed the carrying amount of goodwill. All indefinite-lived assets are reviewed for impairment annually, and as necessary if indicators of impairment are present.

Income Taxes

The Company accounts for income taxes under ASC 740, Income Taxes (“ASC 740”). The Company computes its provision for income taxes using the asset and liability method, under which deferred tax assets and liabilities are calculated based on the basis difference for financial reporting and tax basis of assets and liabilities using enacted tax rates for the year in which the differences are expected to reverse. All deferred income taxes are classified as non-current in the Company’s consolidated balance sheets. The Company records a valuation allowance against net deferred tax assets if, based upon the available evidence, it is more likely than not that some or all of the deferred tax assets will not be realized.

The Company did not recognize certain tax benefits from uncertain tax positions within the provision for income taxes. The Company recognizes a tax benefit only if it is more likely than not the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the financial statements from such positions are then measured based on the largest benefit that has a greater than 50% likelihood of being realized upon settlement. As of December 31, 2020 (Successor), the Company’s estimated gross unrecognized tax benefits were $1,671 thousand, of which $1,586 thousand if recognized would favorably impact the Company’s future earnings. Due to uncertainties in any tax audit outcome, estimates of the ultimate settlement of our unrecognized tax positions may change and the actual tax benefits may differ from the estimates. The Company recognizes interest and penalties accrued on any unrecognized tax benefits as a component of income tax expense.

Advertising Costs

All advertising, promotional and marketing costs are expensed when incurred. During the Successor 2020 Period, Predecessor 2020 Period and Predecessor 2019 Period, advertising costs were $147 thousand, $86 thousand, and $155 thousand, respectively, and are including in Selling, general and administrative within the consolidated statements of operations.

Net Income (Loss) per Unit

The Company has one class of limited liability company units (“Units”). Basic net income (loss) per Unit is computed by dividing income available to Unit holders by the number of weighted average Units outstanding during the period. Diluted net income (loss) per Unit is computed by dividing income available to Unit holders, adjusted for the effects of the presumed issuance of potential Units, if any, by the number of (1) weighted average Units outstanding, plus (2) potentially issuable Units. The Company’s consolidated statements of operations include a presentation of net loss per Unit for the Successor 2020 Period. Net loss per share data has not been presented for the Predecessor 2020 Period and the Predecessor 2019 Period in accordance with ASC 260, Earnings per Share in which earnings per share data is only required for entities that have issued common stock or potential common stock if those securities trade in a public market on a stock exchange or in the over-the counter market.

Accumulated Other Comprehensive Income (Loss)

Accumulated other comprehensive income (loss) (“AOCI”) includes foreign currency translation adjustments.The components of AOCI included $506 thousand, $1 thousand, $(8) thousand of foreign currency translation adjustments for the Successor 2020 Period, the Predecessor 2020 Period and the Predecessor 2019 Period, respectively.

Recently Adopted Accounting Pronouncements

In May 2014, the FASB issued ASU 2014-09, Revenue from Contracts with Customers (Topic 606) (“ASU 2014-09”), which replaces numerous requirements in GAAP, including industry-specific requirements, and provides companies with a single revenue recognition model for recognizing revenue from contracts with customers. The core principle of the new standard is that a company should recognize revenue to depict the transfer of promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods or services in accordance with the five-step model outlined in Topic 606. The two permitted transition methods under the new standard are the full retrospective method, in which case the standard would be applied to each prior reporting period presented, and the cumulative effect of applying the standard would be recognized at the earliest period presented; or the modified retrospective method, in which case the cumulative effect of applying the standard would be recognized at the date of initial application.

Effective January 1, 2019, the Predecessor adopted the requirements of ASU 2014-09 using the modified retrospective method. The Company identified key factors from the five-step model to recognize revenue as prescribed by the new standard that may be applicable to each of the Company’s contract types. Significant customers and contracts were identified, and the Company reviewed these contracts. The Company completed the evaluation of the provisions of these contracts and compared the historical accounting policies and practices to the requirements of the new standard, including the related qualitative disclosures regarding the potential impact of the effects of the accounting policies and a comparison to the Predecessor previous revenue recognition policies. Based on the completed evaluation, the Company concluded the adoption of the requirements of ASU 2014-09 did not have a material impact on the consolidated financial statements.

In January 2017, the FASB issued ASU No. 2017-04, Intangibles—Goodwill and Other (Topic 350): Simplifying the Test for Goodwill Impairment (“ASU 2017-04”), an amendment of the FASB Accounting Standards Codification. ASU 2017-04 eliminates the requirement to measure the implied fair value of goodwill by assigning the fair value of a reporting unit to all assets and liabilities within that unit (“the Step 2 test”) from the goodwill impairment test. Instead, if the carrying amount of a reporting unit exceeds its fair value, an impairment loss is recognized in an amount equal to that excess, limited by the amount of goodwill in that reporting unit. The new standard is effective for its annual or any interim goodwill impairment tests in fiscal years beginning after December 15, 2022. ASU 2017-04 requires prospective adoption and permits early adoption for interim or annual goodwill impairment tests performed on testing dates after January 1, 2017. The Company concluded that there is no impact to its consolidated financial statements from adopting this guidance on January 1, 2020.

In August 2018, the FASB issued ASU No. 2018-15, Intangibles—Goodwill and Other—Internal-Use Software (Subtopic 350-40) (“ASU 2018-15”), an amendment of the FASB Accounting Standards Codification. ASU 2018-15 provides guidance to

determine whether to capitalize implementation costs of a cloud computing arrangement that is a service contract or expense as incurred. Costs of arrangements that do not include a software license should be accounted for as a service contract and expensed as incurred. ASU 2018-15 is effective for fiscal years beginning after December 15, 2019, with early adoption permitted. ASU 2018-15 permits two methods of adoption: prospectively to all implementation costs incurred after the date of adoption, or retrospectively to each prior reporting period presented. The Company concluded that there is no impact to its consolidated financial statements from adopting this guidance on January 1, 2020.

In December 2019, the FASB issued ASU No. 2019-12, Income Taxes (Topic 740): Simplifying the Accounting for Income Taxes (“ASU 2019-12”), an amendment of the FASB Accounting Standards Codification. The amendments in this ASU simplify the accounting for income taxes by removing certain exceptions for intra period tax allocations and deferred tax liabilities for equity method investments and adds guidance whether a step-up in tax basis of goodwill relates to a business combination or a separate transaction. This ASU is effective for fiscal years beginning after December 15, 2020, with early adoption permitted. The Company concluded that there is no impact to its consolidated financial statements from adopting this guidance on January 1, 2020.
