Evolution Petroleum Announces Results for Fiscal 2018 Third Quarter Ended March 31, 2018 and Declares Quarterly Common Stock Dividend
Houston, TX, May 8, 2018 - Evolution Petroleum Corporation (NYSE American: EPM) today announced financial and operating highlights for its fiscal third quarter ended March 31, 2018, with comparisons to the fiscal second quarter ended December 31, 2017 (the "prior quarter") and the quarter ended March 31, 2017 (the "year-ago quarter").
Highlights for the Quarter:

• | Net income was $3.1 million for the quarter, or $0.09 per common share, compared to net income of $2.4 million, or $0.07 per common share in the year-ago quarter.

• | Commenced the planned twelve-well infill drilling program in the Delhi field in late March 2018.

• | Realized oil price for the quarter was $63.56 per barrel, our highest quarterly average oil price since December 2014.

• | Revenues were $10.2 million, an increase of 7.6% over the year-ago quarter.

• | Paid eighteenth consecutive quarterly cash dividend on common shares, in the amount of $0.10 per share and announced a dividend of $0.10 per share for the quarter ending June 30, 2018.

• | Ended the quarter with $28.4 million of working capital, an increase of $0.8 million from the prior quarter, after paying $3.3 million in common stock dividends.

Financial Results for the Quarter Ended March 31, 2018
During the current quarter, Evolution reported operating revenues of $10.2 million, based on an average realized oil price of $63.56 per barrel and an average realized price for natural gas liquids (“NGL’s”) of $34.05

per barrel. The Company has seen steadily increasing oil prices throughout this fiscal year and West Texas Intermediate (“WTI”) prices have further strengthened since the end of March. In the year-ago quarter, operating revenues were $9.5 million, based on an average oil price of $49.29 per barrel and an average realized NGL price of $23.71 per barrel.
Operating income was $3.7 million, down slightly from $3.9 million in the year-ago quarter. Net income for the quarter was $3.1 million, or $0.09 per diluted share, up from $2.4 million, or $0.07 per share, in the year-ago quarter.
Production costs in the Delhi field were $3.4 million in the current quarter, up 19.5% from $2.8 million in the year-ago quarter. The majority of the increase resulted from higher purchased CO 2 costs, as there were increases in both volumes of purchased CO 2 and the cost of purchased CO 2, which is tied directly to realized oil prices in the field.
General and administrative expenses were $1.8 million for the quarter, up from $1.3 million in the year-ago quarter. The majority of this increase resulted from litigation costs and final settlement of legacy litigation in a matter dating back from 2006.
With passage of the Tax Cuts and Jobs Act ("Tax Act") in late December 2017, Evolution’s federal income tax rate dropped from 34% to 21%. The Company’s statutory rate for the current fiscal year ending June 30, 2018 is a blended rate of 27.55%. The Company’s provision for income tax expenses declined significantly from $1.5 million in the year-ago quarter to $0.6 million in the current quarter. The majority of this reduction resulted from benefits of the Tax Act, but there were also other permanent tax differences that we will continue to realize.
Delhi Operations and Capital Spending
As previously reported, the Delhi field experienced weather-related disruptions from abnormal sub-freezing temperatures. Consequently, both oil and NGL production rates suffered from multiple days of shut-ins in addition to scheduled downtimes for maintenance and other repairs both in the field and at the NGL plant. However, production in February and March returned to normalized levels of approximately 7,000 barrels

of oil per day (BOPD) and 1,100 barrels of NGL's per day. The net production volumes of 1,884 barrels of oil equivalent per day (“BOEPD”), were down 16.6% from 2,260 BOEPD in the year-ago quarter.
The operator began the planned twelve-well infill drilling program in the Delhi field during the quarter ending March 31, 2018. This program, which has an expected net cost to the Company of approximately $4.7 million, targets productive oil zones in the developed areas of the field that are not being swept effectively by the current CO 2 flood. This infill program is expected to both add production and increase ultimate recoveries above the current proved producing oil reserves. In conjunction with the infill drilling program, the operator plans to drill the last three wells of a six-well water injection program on the eastern edge of the planned Phase Five expansion of the Delhi field. Evolution’s forecast for the remaining net cost to the Company for this project is approximately $2.1 million. The Company expects all of these projects to be completed by the end of calendar year 2018. In addition to the planned capital spending discussed above, the Company continues to identify and execute successful capital workover projects to improve conformance and production in the field. These projects are not individually material and are unlikely to have a significant impact on capital spending going forward.
During the nine months ended March 31, 2018, the Company incurred approximately $2.3 million of capital expenditures at Delhi. This spending included $0.4 million for capital upgrades to the recycle plant, $0.9 million for CO 2 conformance projects and capital maintenance, $0.7 million for Test Site 5 infrastructure, and $0.3 million for the infill drilling program.
Liquidity and Outlook
“Evolution ended the quarter with $28.4 million in working capital, an increase of $0.8 million from the prior quarter, after paying $3.3 million in common stock dividends during the quarter. Our cash balance was $27.2 million with no debt outstanding. In February, we increased the borrowing base under our credit facility to $40.0 million to better position the Company for a potential acquisition of primarily producing properties. We believe our financial resources are more than sufficient to fund continuing development of the Delhi field, beginning with the infill drilling program, continue our dividend program and capitalize on potential new acquisition opportunities going forward,” commented Randy Keys, President and CEO.

Cash Dividend on Common Stock
The Board of Directors declared a cash dividend of $0.10 per share of common stock, to be paid on June 29, 2018 to common stockholders of record on June 15, 2018. This will be the nineteenth consecutive quarterly cash dividend on the common stock. Common stock dividends, which have been paid since 2013, are a core component of the Company’s strategy.
