See reconciliation to corresponding GAAP measure later in this presentation

In addition to including financial results that are determined in accordance with generally accepted accounting principles in th e United States of America (GAAP), Genie Energy’s investor presentation included Adjusted EBITDA, which is a non - GAAP financial measure. Generally, a non - GAAP financial measure is a numer ical measure of a company’s performance, financial position, or cash flows that either excludes or includes amounts that are not normally excluded or included in the most direc tly comparable measure calculated and presented in accordance with GAAP. Genie Energy’s measure of Adjusted EBITDA consists of gross profit less selling, general and administrative expense, research an d development expense, exploration expense and equity in the net loss of equity method investees, plus depreciation, amortization and stock - based compensation (which are included in selling , general and administrative expense). Another way of calculating Adjusted EBITDA is to start with income (loss) from operations and add depreciation, amortization, stock - based compe nsation, impairment, other operating loss, and the write - off of capitalized exploration costs, and other operating gain. These additions and deductions are non - cash and/or non - routine items i n the relevant periods. Management believes that Genie’s Adjusted EBITDA measure provides useful information to both management and investors by excl udi ng certain expenses and non - routine gains or losses that may not be indicative of Genie’s or the relevant segment’s core operating results. Management uses Adjusted EBITDA, among oth er measures, as a relevant indicator of core operational strengths in its financial and operational decision making. In addition, management uses Adjusted EBITDA to evaluate operatin g p erformance in relation to Genie’s competitors. Disclosure of this financial measure may be useful to investors in evaluating performance and allows for greater transparency to the underl yin g supplemental information used by management in its financial and operational decision - making. Adjusted EBITDA may also be an indicator of the strength and performance of Genie’s a nd the segment’s ongoing business operations, including the ability to fund capital expenditures, and meet working capital needs from current operations (as opposed to cash resources), and to incur and service debt. Management refers to Adjusted EBITDA, as well as the GAAP measures gross profit and income (loss) from operations, on a segme nt and/or consolidated level to facilitate internal and external comparisons to the segments’ and Genie's historical operating results, in making operating decisions, for budget and planning pu rposes, and to form the basis upon which management is compensated. Although depreciation and amortization are considered operating costs under GAAP, they primarily represent the non - cash current period allocation of costs associated with long - lived assets acquired or constructed in prior periods. While Genie Energy’s oil and gas exploration business may be capital intensive, Gen ie Energy does not expect to incur significant depreciation or depletion expense for the foreseeable future. Genie Energy’s operating results exclusive of depreciation and amortization is the refore a useful indicator of its current performance. Stock - based compensation recognized by Genie Energy and other companies may not be comparable because of the various valuation m ethodologies, subjective assumptions and the variety of types of awards that are permitted under GAAP. Stock - based compensation is excluded from Genie Energy’s calculation of Adjust ed EBITDA because management believes this allows investors to make more meaningful comparisons of the operating results of Genie Energy’s core business with the results of ot her companies. However, stock - based compensation will continue to be a significant expense for Genie Energy for the foreseeable future and an important part of employees’ compensation that im pacts their performance. The write - off of capitalized exploration costs, which is a component of income (loss) from operations, is also excluded from the calculation of Adjusted EBITDA. The write - off of capitalized exploration costs is primarily dictated by events and circumstances outside the control of management that trigger an impairm ent analysis. While there may be similar charges in other periods, the nature and magnitude of these charges can fluctuate markedly and do not reflect the performance of Genie Energy’s continu ing operations. Adjusted EBITDA should be considered in addition to, not as a substitute for, or superior to, gross profit, income (loss) fro m o perations, cash flow from operating activities, net income (loss) or other measures of liquidity and financial performance prepared in accordance with GAAP. In addition, Genie’s measurement of A dju sted EBITDA may not be comparable to similarly titled measures reported by other companies.
