August 18, 2015 2 NYSE MKT: EPM Forward-Looking Statement The data contained in this presentation that are not historical facts are “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995, Section 27A of the Securities Act and Section 21E of the Exchange Act. Such statements may relate to capital expenditures, drilling and exploitation activities, production efforts and sales volumes, Proved, Probable, and Possible reserves, operating and administrative costs, future operating or financial results, cash flow and anticipated liquidity, business strategy, property acquisitions, and the availability of drilling rigs and other oil field equipment and services. These forward-looking statements are generally accompanied by words such as “estimated”, “projected”, “potential”, “anticipated”, “forecasted” or other words that convey the uncertainty of future events or outcomes. Although we believe the expectations and forecasts reflected in these and other forward-looking statements are reasonable, we can give no assurance they will prove to have been correct. These statements are based on our current plans and assumptions and are subject to a number of risks and uncertainties such as potential litigation as further outlined in our most recent 10-K and 10-Q. Therefore, the actual results may differ materially from the expectations, estimates or assumptions expressed in or implied by any forward-looking statement made by or on behalf of the Company. Cautionary Note to U.S. Investors – The SEC modified its rules regarding oil and gas reserve information that may be included in filings with the SEC. The current rules allow oil and gas companies to disclose not only Proved reserves, but also Probable and Possible reserves that meet the SEC’s definitions of such terms. We disclose Proved, Probable and Possible reserves in our filings with the SEC. Our reserves as of June 30, 2015 were estimated by DeGolyer & MacNaughton (“D&M”), and reserves in prior years include work by D&M, W. D. Von Gonten & Co., and Pinnacle Energy Services, LLC, all independent petroleum engineering firms. In this presentation, we make reference to Probable and Possible reserves, and “2P” and “3P” reserves that aggregate categories of reserves. These estimates are by their nature more speculative than estimates of Proved reserves and are subject to greater uncertainties, and accordingly the likelihood of recovering those reserves is subject to substantially greater risk. 3 Company Profile NYSE MKT: EPM Vital Statistics Texas/Gulf Coast Focus Overview (FiscalYear End June 30) Shares Outstanding (3/31/2015) (a) 32.9 MM Dilutive Securities (3/31/2015) 0.1 MM Fully Diluted Shares 33.0 MM Share Price Delhi Field Houston Headquarters Evolution Petroleum Founded 2003 Delhi Field Acquired in 2003, Operated By Denbury Resources (3/31/2015) (8/14/2015) $5.03 Market Capitalization (8/7/2015) $166 MM Common Dividend (Annualized) $0.20 Per Share Debt (3/31/2015) None Proved Reserves – 6/30/2015 12.4 MMBOE Proved PV-10 – 6/30/2015 $219 MM % Oil 80% (0% gas) % PDP 59% Avg Production (Gross/Net) 6/30/15 6,328 / 1,677 BOPD Net Working Capital (3/31/2015) $18.4 MM Borrowing Capacity (b) $5 MM (a) Does not reflect shares repurchased by company post 3/31/2015.
