RigNet Non-GAAP Reconciliation Adjusted EBITDA Adjusted EBITDA is a financial measure that is not calculated in accordance with generally accepted accounting principles, or GAAP.  We refer you to the Company’s recent 10-K filing for the year ended December 31, 2018 for a more detailed discussion of the uses and limitations of Adjusted EBITDA. We define Adjusted EBITDA as net loss plus interest expense, income tax expense (benefit), depreciation and amortization, impairment of goodwill, intangibles, property, plant and equipment, (gain) loss on sales of property, plant and equipment, net of retirements, change in fair value of earn-outs and contingent consideration, stock-based compensation, acquisition costs, executive departure costs, restructuring charges and non-recurring items.  Gross Margin We define Gross Margin for any period as the difference between Revenues and Costs of Revenues (excluding Depreciation and Amortization); that difference divided by Revenues.
