Non-GAAP Financial Information

To supplement the Company's financial statements presented in accordance with generally accepted accounting principles in the United States of America (GAAP), the Company reports certain non-GAAP financial measures, including non-GAAP gross margin, non-GAAP operating expenses, non-GAAP operating loss, and non-GAAP adjusted EBITDA. The Company believes that these non-GAAP financial measures provide investors with an additional tool for evaluating the Company's core performance, which management uses in its own evaluation of continuing operating performance, and a baseline for assessing the future earnings potential of the Company. The Company's non-GAAP financial measures may not provide information that is directly comparable to that provided by other companies in the Company's industry, as other companies in the industry may calculate non-GAAP financial results differently, particularly related to non-recurring, unusual items. Non-GAAP financial results should be considered in addition to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. Included below are reconciliations of the non-GAAP financial measures to the comparable GAAP financial measures.

Non-GAAP Definitions

Amortization of intangible assets: Represents amortization expense associated with intangible assets including, but not limited to customer relationships, intellectual property, and trade names acquired in business combinations and asset acquisitions.

Litigation-related expenses: We are involved in various litigation matters that from time-to-time result in settlements. Litigation matters can vary in their characteristics, frequency and significance to our operating results and core business operations. We review litigation matters from both a qualitative and quantitative perspective to determine whether such matters are a normal and recurring part of our business. We include in our GAAP financial statements litigation fees and settlement expenses that we determine to be normal, recurring and routine to our business. When we determine that certain litigation matters are not normal and recurring to our core business operations, we believe excluding these expenses will provide our management and investors with useful incremental information. Litigation fees and settlement expenses excluded from our non-GAAP financial measures in the periods presented relate primarily to patent litigation and other litigation matters that relate directly to the business transformation that we started in 2018 and are discussed more fully in our periodic reports filed with the Securities Exchange Commission.

Other non-recurring expenses: These expenses represent non-recurring expenses that we consider to be one-time in nature.

Purchase accounting adjustments on acquisitions: Includes non-cash expenses incurred as a result of fair value asset step-ups associated with tangible assets acquired from business combinations or asset acquisitions.

Restructuring expenses: From time-to-time, in order to realign the Company's operations or to achieve synergies associated with an acquisition, the Company may eliminate roles or restructure its operations and footprint. In such cases the Company may incur one-time severance and personnel costs associated with workforce reductions, or costs associated with exiting and/or relocating facilities. We exclude these costs as we do not consider such amounts to be part of the ongoing operations.

Stock-based compensation: Stock-based compensation is charged to cost of revenue and operating expenses. We exclude stock-based compensation from certain of our non-GAAP financial measures because we believe that excluding these non-cash expenses provides meaningful supplemental information regarding operational performance. Because of the variety of equity awards used by companies, the varying methodologies for determining stock-based compensation expense, the subjective assumptions involved in those determinations, and the volatility in valuations that can be driven by market conditions outside the Company's control, the Company believes excluding stock-based compensation expense enhances the ability of management and investors to understand and assess the underlying performance of its business over time.

Transaction-related expenses: These expenses represent one-time costs associated with business combinations and asset acquisitions. These items may include but are not limited to consulting and legal fees, contract termination costs and other related deal costs.

Adjusted EBITDA: Represents earnings before non-operating income/expense, taxes, depreciation and amortization, as adjusted for the applicable non-GAAP adjustments previously described.
