Financial Reconciliations and Supplemental Financial Information

Use of Non-GAAP Financial Information 29 GAAP or U.S. GAAP refer to generally accepted accounting principles in the United States. From time to time the Company may include certain “non-GAAP” financial measures in its investor presentations, earnings releases, earnings conference calls or other disclosures. A non-GAAP financial measure is a numerical measure of historical or future performance, financial position or cash flow that includes or excludes amounts that are excluded or included, respectively, in the most directly comparable measure calculated and presented in accordance with GAAP in the Company’s financial statements. Non-GAAP financial measures are provided as alternative methods for assessing the Company’s financial condition and operating results. These measures are not intended to replace the presentation of financial results in accordance with U.S. GAAP and may be different from or otherwise inconsistent with non-GAAP financial measures used by other companies. The presentation of these non-GAAP financial measures supplements other metrics the Company uses to internally evaluate subsidiary businesses and facilitate the comparison of past and present operations. These measures should not be considered in isolation or as a substitute for measures calculated and presented in accordance with GAAP. The tables on the following pages reconcile the most directly comparable GAAP financial measures to Adjusted Net Income / (Loss) for the Company, Adjusted Diluted Earnings Per Share (“EPS”) for the Company, Adjusted Earnings before Interest, Income Taxes, Depreciation and Amortization ("Adjusted EBITDA") for each of the Company and its subsidiaries, and Free Cash Flow (“FCF”) for each of the Company and its subsidiaries. Cash & Public Securities Cash & Public Securities is calculated as Cash & Cash Equivalents plus Equity Securities measured at fair value. Cash & Public Securities is a non-GAAP financial measure used by the Company to measure our liquidity and operating performance. Adjusted Net Income / (Loss) Adjusted Net Income (Loss) is defined as Acacia’s GAAP Net Income (Loss) excluding costs related to certain legacy matters, stock-based compensation, transaction-related costs, amortization of acquired intangibles, any unrealized (gain) / loss on securities, any unrealized (gain) / loss on hedges, any (gain) / loss on non-cash derivatives, and any (gain) / loss on non-cash derivatives. The Company is providing Adjusted Net Income (Loss), a non-GAAP financial measure, because the metric provides investors with useful supplemental information in comparing the operating results across reporting periods by excluding items that are not considered indicative of core operating performance. Adjusted Diluted Earnings Per Share (EPS) Adjusted Diluted EPS is defined as Adjusted Net Income (Loss) divided by the Company’s weighted average diluted share count as of the relative period end date. The Company is providing its Adjusted Diluted EPS, a non-GAAP financial measure, because the metric provides investors with useful supplemental information in comparing the operating results across reporting periods by excluding items that are not considered indicative of core operating performance. Total Company Adjusted EBITDA Total Company Adjusted EBITDA is defined as net income / (loss) before net income / (loss) attributable to noncontrolling interests, income tax (benefit) / expense, interest expense, interest income and other, net, loss / (gain) on foreign currency exchange, net realized and unrealized (gain) / loss on derivatives, net realized and unrealized loss / (gain) on investments, legacy legal expenses, depreciation, depletion and amortization, stock-based compensation, realized hedge gain / (loss), transaction-related costs, and costs related to the legacy items. Operated Segment Adjusted EBITDA Operated Segment Adjusted EBITDA is the aggregate of Energy Operations Adjusted EBITDA, Manufacturing Operations Adjusted EBITDA, Industrial Operations Adjusted EBITDA, and Intellectual Property Operations Adjusted EBITDA. See below for the definition of each of those measures. The Company is providing Total Company Adjusted EBITDA and Operated Segment Adjusted EBITDA, non-GAAP financial measures, because management believes these metrics provide investors with useful supplemental information in comparing the operating results across reporting periods by excluding items that are not considered indicative of core operating performance. These measures are not intended to replace the presentation of financial results in accordance with GAAP and may be different from or otherwise inconsistent with similar non-GAAP financial measures used by other companies. The presentation of these non-GAAP financial measures supplements other metrics the Company uses to internally evaluate its subsidiary businesses and facilitate the comparison of past and present operating performance. These measures should not be considered in isolation or as a substitute for measures calculated and presented in accordance with GAAP. Free Cash Flow (FCF) Free Cash Flow is defined as net cash provided by (used in) operating activities, less net purchases of property and equipment, oil and gas properties, and patent acquisitions (“Capital Expenditures”). The Company is providing Free Cash Flow, a non-GAAP financial measure, because it believes free cash flow gives investors a good sense of how much cash flows are available to be used for de-levering, making acquisitions, repurchasing shares or similar uses of cash. Energy Operations Adjusted EBITDA Energy Operations Adjusted EBITDA is defined as operating income / (loss) for Acacia’s Energy Operations before depreciation, depletion and amortization expense and transaction-related costs, and including realized hedge gain / (loss). The Company is providing its Energy Operations Adjusted EBITDA, a non-GAAP financial measure, because the metric provides investors with useful supplemental information in comparing the operating results across reporting periods by excluding items that are not considered indicative of core operating performance. Industrial Operations Adjusted EBITDA Industrial Operations Adjusted EBITDA is defined as operating income / (loss) for Acacia’s Industrial Operations before amortization of acquired intangibles and depreciation and amortization expense. The Company is providing its Industrial Operations Adjusted EBITDA, a non-GAAP financial measure, because the metric provides investors with useful supplemental information in comparing the operating results across reporting periods by excluding items that are not considered indicative of core operating performance. Intellectual Property Operations Adjusted EBITDA Intellectual Property Operations Adjusted EBITDA is defined as operating income / (loss) for Acacia’s Intellectual Property Operations before patent amortization, depreciation and amortization expense and stock-based compensation. The Company is providing Intellectual Property Operations Adjusted EBITDA, a non-GAAP financial measure, because the metric provides investors with useful supplemental information in comparing the operating results across reporting periods by excluding items that are not considered indicative of core operating performance. Manufacturing Operations Adjusted EBITDA Manufacturing Operations Adjusted EBITDA is defined as operating income / loss for Acacia’s Manufacturing Operations before amortization of acquired intangibles, depreciation and amortization expense, and transaction-related costs. The Company is providing its Manufacturing Operations Adjusted EBITDA, a non-GAAP financial measure, because the metric provides investors with useful supplemental information in comparing the operating results across reporting periods by excluding items that are not considered indicative of core operating performance. Parent Costs Parent Costs are defined as operating income / (loss) attributable to Parent before depreciation and amortization expense, stock-based compensation, transaction-related costs, and costs related to certain legacy matters attributable to the Parent organization. The Company is providing Parent Costs, a non-GAAP financial measure, because it believes it gives investors a clear picture of normalized Parent-level expenses.
