GASTAR EXPLORATION ANNOUNCES

FIRST QUARTER 2015 RESULTS

• First Quarter Production Increased 30% Year-Over-Year to 12.6 MBoe/d

• Announced Improved Liquidity Through Agreement to Sell Non-Core Mid-Continent Assets

HOUSTON, May 7, 2015 - Gastar Exploration Inc. (NYSE MKT: GST) (“Gastar”) today reported financial and operating results for the three months ended March 31, 2015.

Net loss attributable to Gastar’s common stockholders as reported for the first quarter of 2015 was $3.0million, or a loss of $0.04 per share. Excluding a $4.3 million gain resulting from the mark-to-market of outstanding hedge positions, adjusted net loss attributable to common stockholders was $7.3 million, or a loss of $0.09 per share. This compares to a first quarter 2014 reported net loss of $2.0 million, or a loss of $0.03 per share, a first quarter 2014 adjusted net income of $1.4 million, or $0.02 per diluted share, which excludes the impact of a $3.2 million loss resulting from the mark-to-market of outstanding hedge positions, $30,000 of acquisition costs and non-recurring corporate restructuring charges of $205,000 and a fourth quarter 2014 adjusted net income of $1.8 million, or $0.02 per diluted share, which excludes a $24.9 million gain resulting from the mark-to-market of outstanding hedge positions. (See the accompanying reconciliation of net loss to net income (loss) excluding special items at the end of this news release.)

Adjusted earnings before interest, income taxes, depreciation, depletion and amortization (“adjusted EBITDA”) for the first quarter of 2015 was $20.0 million, a decrease of 23% compared to $25.9 million for both the first quarter of 2014 and the fourth quarter of 2014. (See the accompanying reconciliation of net loss to adjusted EBITDA, a non-GAAP number, at the end of this news release.)

Revenues from oil, condensate, natural gas and natural gas liquids (“NGLs”), before the impact of hedging activities, declined 38% to $24.1 million in the first quarter of 2015 from $38.8 million in the first quarter

1

of 2014 and decreased 27% from $33.1 million in the fourth quarter of 2014. The decrease in oil, condensate, natural gas and NGLs revenues from first quarter of 2014 to first quarter of 2015 was primarily the result of a 52% decrease in weighted average realized equivalent prices partially offset by a 30% increase in production. The decrease from fourth quarter of 2014 revenues was primarily due to a 31% decline in equivalent product pricing partially offset by an 8% increase in average daily production.

Revenues from liquids (oil, condensate and NGLs) represented approximately 72% of total production revenues in the first quarter of 2015, compared to 60% for the first quarter of 2014 and 77%during the fourth quarter of 2014. We had commodity derivatives contracts in place covering approximately 56% of our natural gas production and 62% of our liquids production for the first quarter of 2015. Commodity derivative contracts settled during the period resulted in a $6.0 million increase in revenue for the first quarter of 2015, compared to a reduction in revenue of $3.4 million for the first quarter of 2014 and an increase in revenue of $3.5 million for the fourth quarter of 2014. First quarter 2015 hedge benefit enhanced our barrel of oil equivalent pricing by approximately 25%, while in the first quarter of 2014, it reduced our oil equivalient pricing by approximately 9%. We continue to maintain an active hedging program covering a portion of estimated future production, which is reported in our periodic filings with the U.S. Securities and Exchange Commission (“SEC”).

Average daily production for the first quarter of 2015 was 12,600 barrels of oil equivalent per day (“Boe/d”) (on a 6:1 gas (Mcf) to liquids (barrel) equivalent basis) as compared to 9,700 Boe/d in the first quarter of 2014 and 11,700 Boe/d in the fourth quarter of 2014. Oil, condensate and NGLs as a percentage of total equivalent production volumes were 52% in the first quarter of 2015 compared to 41% in the first quarter of 2014 and 53% in the fourth quarter of 2014.

J. Russell Porter, Gastar's President and CEO, commented, “We are pleased with our first quarter operating results as they reflect our continued success in developing our Mid-Continent WEHLU acreage, as well as the contribution of wells recently completed in our Hunton AMI acreage and on our Appalachian Basin leasehold. Our most recent WELHU wells are performing as expected or better, which reinforces our decision to focus our 2015 capital in an area that offers a solid rate of return and the opportunity to add substantial proven reserves. We expect to continue to demonstrate impressive deliverability associated with our Utica/Point Pleasant assets by completing our second Utica/Point Pleasant well in Marshall County, West Virginia later this month.”

“As announced yesterday, we are divesting 19,000 net acres of non-core leasehold in the Mid-Continent area. This sale allows us to further enhance our liquidity position while retaining a strong acreage position with Hunton Limestone and Stack Play potential. We are currently evaluating the possibility of drilling a Stack Play well in the Meramec Shale/Mississippi Lime formation later this year on our Mid-Continent acreage. While we plan to maintain a conservative approach to our 2015 capital plan, we have been

2

closely monitoring the success of other nearby operators targeting the Meramec Shale/Mississippi Lime formation and believe an operated drill test could help define the value of our Stack Play potential.”

The following table provides a summary of Gastar’s production volumes and average commodity prices for the three months ended March 31, 2015 and 2014:

	For the Three Months Ended March 31,

_____________________________

(1) The impact of hedging includes the gain (loss) on commodity derivative contracts settled during the periods presented.

Lease operating expenses (“LOE”) were $6.0 million for the first quarter of 2015, versus $4.0 million in the first quarter of 2014 and $6.3 million in the fourth quarter of 2014. Compared to the first quarter of 2014, LOE in the first quarter of 2015 increased $2.0 million due to one-time workover costs of $1.4 million for production enhancement on five wells in our operated WEHLU acreage as well as higher frack water disposal costs associated with bringing new wells online and higher overall costs associated with producing oil versus natural gas. Compared to the fourth quarter of 2014, LOE was down due to operating expense reduction initiatives regarding electrical submersible pump, or “ESP”, conversions to rod pumps and lower AMI operating costs. LOE per barrel of oil equivalent (“Boe”) of production was $5.30 in the first quarter of 2015 versus $4.65 in the first quarter of 2014 and $5.83 in the fourth quarter of 2014. Excluding workover costs, LOE per Boe for first quarter of 2015 was $4.09 compared to $4.65 per Boe for the first quarter of 2014 and $5.26 per Boe for the fourth quarter of 2014.

3

Depreciation, depletion and amortization expense (“DD&A”) was $14.5 million in the first quarter of 2015, up from $12.4 million in both the first and fourth quarters of 2014. The year-over-year increase in DD&A expense was the result of 30% higher production volumes partially offset by a 10% lower DD&A rate per Boe that resulted from higher year-end proved reserve volumes. DD&A increased sequentially due to an increase in the DD&A rate and higher production volumes in the first quarter of 2015. The DD&A rate per Boe for the first quarter of 2015 was $12.75 compared to $14.23 for the first quarter of 2014 and $11.53 in the fourth quarter of 2014.

General and administrative (“G&A”) expense was $4.2 million in the first quarter of 2015 compared to $4.8 million in the first quarter of 2014 and $3.8 million in the fourth quarter of 2014. G&A expense for the first quarter of 2015 included $1.5 million of non-cash, stock-based compensation expense, consistent with the first quarter of 2014 and compared to $1.2 million in the fourth quarter of 2014. Excluding stock-based compensation expense, cash G&A expense decreased to $2.7 million in the first quarter of 2015 from $3.2 million in the first quarter of 2014 and increased slightly from $2.6 million in the fourth quarter of 2014. The decrease from the first quarter of 2014 was primarily due to reduced legal costs.

Interest expense totaled $7.6 million in the first quarter of 2015, compared to $6.9 million in the first quarter of 2014 and $6.8 million in the fourth quarter 2014. The increase was the result of additional interest and charges related to increased borrowings under our revolving credit facility.

Operations Review and Update

Mid-Continent

Net production from the Mid-Continent area increased to an average of 5,900 Boe/d in the first quarter of 2015, compared to 3,300 Boe/d in the first quarter of 2014 and 5,600 Boe/d in the fourth quarter of 2014. First quarter 2015 Mid-Continent equivalent production consisted of approximately 57% oil, 25% natural gas and 18% NGLs.

Within our AMI acreage, six gross (3.1 net) non-operated wells were placed on production during the first quarter of 2015. We expect to complete and bring on production a total of four gross (2.0 net) wells in the second quarter of 2015, of which two gross (1.1 net) non-operated wells have already been placed on production.

The table below shows wells brought on production or for which drilling operations have commenced since the beginning of the first quarter of 2015 within our original AMI in the Hunton Limestone formation (all of which are operated by our joint venture partner):

During the first quarter of 2015, we completed three gross (2.9 net) operated wells on our WEHLU acreage. These included one gross (1.0 net) vertical well, the Warsaw 33-1H, and two gross (2.0 net) horizontal wells, the Warsaw 33-2H targeting the upper Hunton and the Warsaw 33-3H targeting the lower Hunton, all of which are located on the southern portion of our WEHLU acreage. We have three gross (2.9 net) wells awaiting completion. We expect to commence production operations on these wells over the next couple of weeks. Additionally, we have begun drilling operations on the Jetson 8-1H targeting the upper Hunton and the Davis 9-2H targeting the lower Hunton. On both the Jetson and Davis pads, we plan to drill an additional horizontal well targeting the lower and upper Hunton, respectively. The two Davis wells are projected to be on production in July 2015 and the two Jetson wells in August 2015. We expect to complete and bring on production three gross (2.9 net) operated wells in the second quarter of 2015 and seven gross (6.9 net) operated wells in the third quarter of 2015.

The table below shows wells brought on production or for which drilling operations have commenced since the beginning of the first quarter of 2015 within our operated acreage in the Hunton Limestone formation, all of which are located within WEHLU:

(3) The Warsaw 33-1 is a vertical well.

In the Mid-Continent, our net capital expenditures in the first quarter of 2015 totaled $29 million. Our total 2015 capital expenditure budget in the Mid-Continent is $69 million, of which $60 million has been allocated to drilling and completion and $9 million to lease extensions.

Appalachian Basin

Net production from the Appalachian Basin area averaged 6,700 Boe/d in the first quarter of 2015, compared to 6,400 Boe/d for the first quarter of 2014 and 6,100 Boe/d in the fourth quarter of 2014. Year-over-year and sequential production volume increases were due to seven gross (3.5 net) Armstrong Marcellus Shale wells and three gross (1.5 net) Hansen Marcellus Shale wells that were brought on production in mid-to-late December 2014 as well as three gross (1.5 net) Goudy Marcellus Shale wells that were brought online in early March 2015.

In late April 2015, the third party mid-stream gathering system incurred a leak south of our leasehold position. During the nine days of repair operations, our existing production was curtailed by approximately 19,300 net Boe comprised of approximately 64,500 net Mcf of natural gas, approximately 2,300 net barrels of condensate and approximately 6,300 barrels of NGLs. The leak repair also delayed the timing and flow rate of new wells being turned to sales. The gathering system repairs have been completed.

In early April 2015, two gross (1.0 net) Marcellus Shale wells on the Hoyt pad were brought online. Additionally, two gross (1.0 net) Marcellus Shale wells and one gross (0.5 net) Utica/Point Pleasant well on the Blake pad are expected to be completed and brought on production late May 2015. The Utica/Point Pleasant well has been fracked with a lateral length of 6,600 feet, and will be brought on production at a restricted flow rate to maximize estimated ultimate recovery of reserves. We continue to be

6

encouraged by the high initial production rates of third party Utica Shale wells surrounding our acreage. At this time, we have no additional wells budgeted to be drilled and completed in the Appalachian Basin for the remainder of 2015. We will continue to monitor commodity prices and services costs in the area and may elect to resume drilling when economic conditions warrant.

Net capital expenditures in the Appalachian Basin for the first quarter of 2015 totaled $12 million. We have allocated approximately $27 million of our total 2015 capital budget to the Appalachian Basin, of which $19 million is for the completion of eight gross (4.0 net) drilled wells as noted above and $8million is primarily for acquiring additional mineral rights in the area.

Liquidity

At March 31, 2015, we had approximately $12.1 million in available cash and cash equivalentsand $135 million of availability under our $200 million revolving credit facility. We expect to fund our remaining 2015 capital program through existing cash balances, internally generated cash flow from operating activities, borrowings under the revolving credit facility, property sales and possible capital markets transactions, or some combination thereof.

Guidance for the Second Quarter of 2015

We are reiterating our previously issued guidance for the full year 2015 and providing the following guidance for the second quarter of 2015:

Production	Second Quarter 2015(1)	Full-Year 2015(1)
Net average daily (MBoe/d)(2)	12.5 - 13.1	11.5 - 13.4
Liquids percentage	51% - 54%	51% - 55%
Cash Operating Expenses	Second Quarter 2015	Full-Year 2015
Production taxes (% of production revenues)	4.8% - 5.3%	4.3% - 4.8%

NON-GAAP FINANCIAL INFORMATION AND RECONCILIATION

We use both GAAP and certain non-GAAP financial measures to assess performance. Generally, a non-GAAP financial measure is a numerical 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 directly comparable measure calculated and presented in accordance with GAAP. Our management believes that these non-GAAP measures provide useful supplemental information to investors in order that they may evaluate our financial performance using the same measures as management. These non-GAAP financial measures should not be considered as a substitute for, or superior to, measures of financial performance prepared in accordance with GAAP. In evaluating these measures, investors should consider that the methodology applied in calculating such measures may differ among companies and analysts. A reconciliation is provided below outlining the differences between these non-GAAP measures and their most directly comparable financial measure calculated in accordance with GAAP.
