Evolution Petroleum Increases Common Stock Dividend by 33% to $0.10 per Share; Announces Results for Fiscal 2018 Second Quarter Ended December 31, 2017
Houston, TX, February 7, 2018 - Evolution Petroleum Corporation (NYSE American: EPM) today announced that the Board of Directors declared a quarterly cash dividend to common shareholders of $0.10 per share, an increase of 33% over the previous rate of $0.075 per share. The quarterly dividend, which amounts to $0.40 per share on an annual basis, will be paid on March 29, 2018 to shareholders of record on March 15, 2018.
Evolution today also reported financial and operating highlights for its fiscal second quarter ended December 31, 2017, with comparisons to the fiscal first quarter ended September 30, 2017 (the "prior quarter") and the quarter ended December 31, 2016 (the "year-ago quarter").
Highlights for the Quarter:

• | Revenues of $11.1 million, an increase of 30% over both the prior and year-ago quarter.

• | Net income of $9.9 million for the quarter, $0.30 per common share, compared to net income of $0.07 per common share in both the prior and year-ago quarter.

• | Net income for the quarter includes a one-time $6.0 million non-cash tax benefit related to passage of the Tax Cuts and Jobs Act of 2017.

• | Realized oil price for the quarter of $57.30 per barrel, the highest quarterly average since June 2015.

• | Evolution paid its seventeenth consecutive quarterly cash dividend on common shares, in the amount of $0.075 per share, and announced an increase in the dividend rate to $0.10 per share for the quarter ending March 31, 2018.

• | The Company ended the quarter with $27.6 million of working capital, an increase of $3.2 million from the prior quarter, after paying $2.5 million in common stock dividends.

”Evolution reported another outstanding quarter, with very strong cash flows,” said Randy Keys, President and CEO. “After three years of low oil prices, we saw a meaningful turnaround in oil and NGL prices during the quarter. Prices during January 2018 have been at higher levels than the quarter. We are pleased that

this brighter outlook for prices and cash flows allowed the Board to increase our common dividend to $0.40 per share on an annual basis. The increase restores the dividend to the original level set in December 2013, when oil prices were in the $100 per barrel range. We are able to make this increase, despite oil prices well below levels from 2013, based on higher production and management of costs. Even with higher dividends, we have reserved more than half of our projected near-term cash flow for future investments in Delhi and other potential projects.
“Tax reform also carries significant benefits for Evolution. With the lower corporate tax rate, the dividends to our shareholders will now carry a much lower combined income tax rate than under the previous tax regime. This makes us more tax-efficient as a yield-oriented company.”
Financial Results for the Quarter Ended December 31, 2017
In the current quarter, Evolution reported record operating revenues of $11.1 million, based on an average realized oil price of $57.30 per barrel and an average realized NGL price of $33.85 per barrel. In the prior quarter, operating revenues were $8.5 million, based on an average oil price of $46.96 per barrel and an average realized NGL price of $28.07 per barrel. Net production volumes for the quarter were 2,215 barrels of oil equivalent per day (“BOEPD”), an increase of 6% from 2,086 BOEPD in the prior quarter and an increase of 12% from the year-ago quarter. Operating income was $4.8 million, up $2.3 million, or 90%, from the prior quarter.
Net income for the quarter was $9.9 million, or $0.30 per diluted share, up from $2.1 million, or $0.07 per share, in the prior quarter. We recorded a one-time non-cash income tax benefit of $6.0 million in the quarter to adjust our liability for deferred income taxes to the lower tax rate in the 2017 Tax Cuts and Jobs Act.
Production costs in the Delhi field were $2.9 million in the current quarter, up less than 1% from the prior quarter, but up $0.6 million, or 27%, from the year-ago quarter. The current and prior quarters included approximately $0.4 and $0.5 million, respectively, of operating costs from the NGL plant which commenced operation in January 2017. Purchased CO 2 volumes were 69.7 million cubic feet (MMcf) per day, unchanged from the prior quarter. However, our total CO 2 costs were up by 16% as a result of higher realized oil prices in the field, which are directly tied to the price per Mcf for purchased CO 2.
General and administrative (“G&A”) expenses were $1.7 million for the quarter, of which $0.5 million were noncash stock-based compensation expenses and approximately $1.2 million were cash costs. During the quarter, the Company incurred additional engineering and other costs associated with the evaluation of

potential property acquisitions. The Company continues to carefully manage G&A costs to maximize funds available for dividends and potential growth opportunities.
Delhi Operations and Capital Spending
Gross oil production at Delhi averaged 7,370 barrels per day during the quarter, a 7% increase from the prior quarter. Gross NGL production for the quarter was 1,079 barrels per day, up 3% from the prior quarter. As previously disclosed, Evolution completed a strategic capital upgrade to the inlet of the recycle plant in August. Results from the NGL plant after completion of this project have been very positive, with the plant operating at or near maximum capacity and efficiency. During the extreme cold of January 2018, we experienced two weather-related disruptions to production in the field, including an extended outage at the NGL plant. These issues have been remedied and the field and NGL plant are producing at normal capacity.
Evolution will begin a 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 $4.7 million, will target productive oil zones in the developed area of the field which 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. At the same time, we will 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 costs of this project is $2.3 million. The Company expects all of these projects to be completed during the quarter ending September 30, 2018.
During the quarter, Evolution incurred approximately $0.8 million on capital projects, the majority of which was spent on the water injection program to prepare for the Phase Five expansion. The Company also continues to identify and execute successful capital workover projects to improve conformance of the field. These projects are not individually material and are unlikely to have a significant impact on our capital spending during the fiscal year.
Liquidity and Outlook
Evolution ended the quarter with $27.6 million in working capital, an increase of $3.2 million from the prior quarter, after paying $2.5 million in common stock dividends during the quarter. The Company’s cash balance was $25.7 million with no debt outstanding. The Company recently increased the borrowing base under our credit facility to $40.0 million to better position us for the potential acquisition of primarily producing properties. The Company believes its financial resources are more than sufficient to fund continuing development of the Delhi field, beginning with the infill drilling program in early 2018, and we believe we also have the financial resources to continue our dividend program and capitalize on potential new acquisition opportunities going forward.
