Discussion Regarding the Use of Non-GAAP Financial Measures

Our earnings release contains some or all of the following financial measures that have not been calculated in accordance with United States Generally Accepted Accounting Principles (“GAAP”): (i) non-GAAP gross profit and gross margin, (ii) non-GAAP operating loss and (iii) non-GAAP net income(loss). As set forth in the “Unaudited Reconciliations of Non-GAAP Financial Measures” table, we derive such non-GAAP financial measures by excluding certain expenses and other items from the respective GAAP financial measure that is most directly comparable to each non-GAAP financial measure. Management uses these non-GAAP financial measures to evaluate operating performance and compare it against past periods, make operating decisions, forecast for future periods, compare our operating performance against peer companies and to determine payments under compensation programs. These non-GAAP financial measures provide management with additional means to understand and evaluate the operating results and trends in our ongoing business by eliminating certain expenses and other items that management believes might otherwise make comparisons of our ongoing business with prior periods and competitors more difficult, obscure trends in ongoing operations or improve management’s ability to forecast future periods.

We provide investors with non-GAAP gross profit and gross margin, non-GAAP operating loss, and non-GAAP net income (loss) because we believe it is important for investors to be able to closely monitor and understand changes in our ability to generate income from ongoing business operations. We believe these non-GAAP financial measures give investors an additional method to evaluate historical operating performance and identify trends, an additional means of evaluating period-over-period operating performance and a method to facilitate certain comparisons of our operating results to those of our peer companies. We further believe these non-GAAP measures allow investors to assess the overall financial performance of our ongoing operations by eliminating the impact of acquisition-related expenses (including acquisition-related professional fees, deemed compensation expense, amortization of acquisition-related intangibles and expenses recognized in relation to changes in contingent consideration obligations), expenses recognized in relation to fair value changes in simple agreements for future equity (“SAFEs”) issued by indie, non-cash interest expenses related to the amortization of debt discounts and issuance costs and non-cash tax expenses. We believe that disclosing these non-GAAP financial measures contributes to enhanced financial reporting transparency and provides investors with added clarity about complex financial performance measures.

We calculate non-GAAP gross profit by subtracting cost of sales from revenue. Note, all costs incurred in relation to our contract revenues are expensed as incurred as research and development costs and are therefore not included in the computation of non-GAAP gross profit. We calculate non-GAAP operating loss by excluding from GAAP operating loss, any acquisition-related expenses (including acquisition-related professional fees, deemed compensation expense, and amortization of acquisition-related intangibles). We calculate non-GAAP net income (loss) by excluding from GAAP net income (loss), any acquisition-related expenses (including acquisition-related professional fees, deemed compensation expense, amortization of acquisition-related intangibles and expenses recognized in relation to changes in contingent consideration obligations), expenses recognized in relation to fair value changes in SAFEs issued by indie during 2020, non-cash interest expenses related to the amortization of debt discounts and issuance costs and non-cash tax expenses.

We exclude the items identified above from the respective non-GAAP financial measure referenced above for the reasons set forth with respect to each such excluded item below:

Acquisition-related expenses - including such items as, when applicable, amortization of acquired intangible assets, fair value adjustments to contingent consideration, fair value charges incurred upon the sale of acquired inventory, and acquisition-related expenses because they are not considered by management in making operating decisions and we believe that such expenses do not have a direct correlation to our future business operations and thereby including such charges do not necessarily reflect the performance of our ongoing operations for the period in which such charges or reversals are incurred.

SAFEs and other fair value adjustments - because these adjustments (1) are not considered by management in making operating decisions, (2) are not directly controlled by management, (3) do not necessarily reflect the performance of our ongoing operations for the period in which such charges are recognized and (4) can make comparisons between peer company performance less reliable.

Non-cash interest expense - related to the amortization of debt discounts, warrants, and issuance costs because (1) these expenses are not considered by management in making decision with respect to financing decisions, and (2) these generally reflect non-cash costs.

Deferred tax charges -because such charges do not result in a current period tax payment.

The non-GAAP financial measures presented should not be considered in isolation and are not an alternative for the respective GAAP financial measure that is most directly comparable to each such non-GAAP financial measure. Investors are cautioned against placing undue reliance on these non-GAAP financial measures and are urged to review and consider carefully the adjustments made by management to the most directly comparable GAAP financial measures to arrive at these non-GAAP financial measures. Non-GAAP financial measures may have limited value as analytical tools because they may exclude certain expenses that some investors consider important in evaluating our operating performance or ongoing business performance. Further, non-GAAP financial measures are likely to have limited value for purposes of drawing comparisons between companies as a result of different companies potentially calculating similarly titled non-GAAP financial measures in different ways because non-GAAP measures are not based on any comprehensive set of accounting rules or principles.

To the extent our disclosures contain forward-looking estimates of non-GAAP financial measures, these measures are provided to investors on a prospective basis for the same reasons (set forth above) we provide them to investors on a historical basis. We are generally unable to provide a reconciliation of our forward-looking non-GAAP measures because certain information needed to make a reasonable forward-looking estimate of such non-GAAP measures are difficult to predict and estimate and is often dependent on future events that may be uncertain or outside of our control. Such events may include unanticipated changes in our GAAP effective tax rate, unanticipated one-time charges related to asset impairments (fixed assets, inventory, intangibles, or goodwill), unanticipated acquisition-related expenses, unanticipated settlements, gains, losses and impairments and other unanticipated items not reflective of ongoing operations. Our forward-looking estimates of both GAAP and non-GAAP measures of our financial performance may differ materially from our actual results and should not be relied upon as statements of fact.
