Forward Looking Statements and Other Disclosures Safe Harbor Statement Some of the Statements in this document concerning future Company performance will be forward-looking within the meanings of the securities laws. Actual results may materially differ from those discussed in these forward-looking statements. You should refer to the additional information contained in Chesapeake Utilities’ Annual Report on Form 10-K for the year ended December 31, 2020 filed with the SEC and other subsequent SEC filings concerning factors that could cause those results to be different than contemplated in today’s discussion. Reg D Disclosure Today’s discussion includes certain non-GAAP financial measures as defined under SEC Regulation D. Although non-GAAP measures are not intended to replace GAAP measures for evaluation of Chesapeake’s performance, Chesapeake believes that portions of the presentation, which include certain non-GAAP financial measures, provide a helpful comparison for an investor’s evaluation purposes. Gross Margin (Non-GAAP Measure) Gross Margin is determined by deducting the cost of sales from operating revenue. Cost of sales includes the purchased fuel cost for natural gas, electric and propane distribution operations and the cost of labor spent on different revenue-producing activities and excludes depreciation, amortization and accretion. Other companies may calculate gross margin in a different manner.
