Fourth Quarter 2015 Financial Results

During the fourth quarter, our net daily production averaged 624 MMcfe/d (100% natural gas), a 57% increase relative to fourth quarter 2014 production. This quarterly production growth was primarily driven by improved well performance and wells online ahead of schedule.

Fourth quarter average realized natural gas price, before the effect of hedges, was $2.05 per Mcf. After giving effect to hedges, our average natural gas price was $3.39 per Mcf. Approximately 91% of our fourth quarter production received favorable Gulf Coast, TCO and Midwest pricing, as compared to 76% of third quarter 2015 production, due to increasing premium market exposure through our firm transportation portfolio. Our average basis differential for the quarter was ($0.14) per MMBtu, while TETCO M2 and Dominion South averaged ($0.93) and ($0.92) per MMBtu, respectively, below NYMEX Henry Hub for the quarter.

Per unit cash production costs (lease operating; gathering, compression and transportation; and production taxes and impact fees) were $0.71 per Mcfe. Adjusted EBITDAX for the quarter was $132.2 million. We reported adjusted net income⁽³⁾ of $22.0 million, or $0.16 per share, after excluding unrealized gains on derivative contracts and other non-recurring income and expense items.

2015 Proved Reserves

Proved reserves increased by 30% from year-end 2014 to over 1.7 Tcfe at December 31, 2015. The Marcellus Shale accounted for approximately 75% of our total proved reserves and the Utica Shale accounted for the substantial remainder. Our year-end 2015 proved reserves were 99.8% natural gas with an 8-year estimated reserve life, based on 2015 production. As of December 31, 2015, approximately 15% of our 1,369 total net identified drilling locations were classified as proved.

Proved Developed Reserves

Proved developed reserves increased by 57% from year-end 2014 to approximately 1.0 Tcfe, as of December 31, 2015. Approximately 60% of our total proved reserves were classified as proved developed, as compared to 49% at year-end 2014. There were 156 net wells categorized as proved developed at year-end 2015, consisting of 143 net producing wells and 13 net non-producing wells.

Proved Undeveloped Reserves

Proved undeveloped reserves increased by 3% from year-end 2014 to approximately 685 Bcfe, as of December 31, 2015. There were 54 net locations categorized as proved undeveloped at year-end 2015, including 15 net Utica locations. Based on 2015 well cost assumptions, our 685 Bcfe of proved undeveloped reserves will require an estimated $517 million of future development capital over the next five years, which results in an estimated average development cost of $0.75 per Mcfe for our proved undeveloped reserves.

Proved Reserves PV-10

Using NYMEX strip pricing, the pre-tax present value discounted at 10% (pre-tax PV-10) for our year-end 2015 total proved reserves was $1.4 billion, including $265 million of hedge value. Our pre-tax PV-10 value of our proved developed reserves was $935 million.

Using SEC pricing, the pre-tax PV-10 of our year-end 2015 total proved reserves was $1.3 billion, including $408 million of hedge value. Our pre-tax PV-10 value of our proved developed reserves was $802 million. Our estimated proved reserves and PV-10 value were determined using an SEC Henry Hub spot price of $2.59 per MMBtu, which is based on the 12-month unweighted arithmetic average of the first day of the month price for each month in the January through December 2015 period and is not indicative of current forward prices.

Commodity Hedge Position

As depicted in the table below, we have 662 BBtu/d hedged in 2016 at a weighted average floor price of $3.26 MMBtu. Our 2016 hedges cover 87% of our 2016 production (based on the midpoint of guidance). Additionally, for the first quarter of 2016 we have 556 BBtu/d hedged at a weighted average floor price of $3.30 per MMBtu. For 2017 we have 563 BBtu/d hedged at a weighted average floor price of $3.14 MMBtu. Our 2017 hedges are expected to cover more than half of our 2017 production. Please see the “Derivatives Information” table at the end of this press release for more detailed information about our derivatives positions.

Firm Transportation and Realized Gas Pricing

In 2016, we anticipate that approximately 70% of our production will be transported to premium gas markets outside of Appalachia. The following tables provide basis exposure as a percentage of our production and average differentials to NYMEX for actual results through December 31, 2015 and estimated results for the first quarter of 2016 and full year 2016 and 2017.

Supplemental Non-GAAP Financial Measure

(Unaudited)

Adjusted EBITDAX is a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. We define Adjusted EBITDAX as net income (loss) before non-controlling interest; interest expense; income taxes; depreciation, depletion and amortization; amortization of deferred financing costs; amortization of intangible assets; derivative fair value (gain) loss, excluding net cash receipts on settled derivative instruments; non-cash stock compensation expense; non-cash incentive unit expense; exploration expenses; and other non-recurring items. Adjusted EBITDAX is not a measure of net income as determined by United States generally accepted accounting principles, or GAAP.

Management believes Adjusted EBITDAX is useful because it allows them to more effectively evaluate our operating performance and compare the results of our operations from period to period and against our peers without regard to our financing methods or capital structure. We exclude the items listed above from net income in arriving at Adjusted EBITDAX because these amounts can vary substantially from company to company within our industry depending upon accounting methods and book values of assets, capital structures and the method by which the assets were acquired. Adjusted EBITDAX should not be considered as an alternative to, or more meaningful than, net income as determined in accordance with GAAP or as an indicator of our operating performance or liquidity. Certain items excluded from Adjusted EBITDAX are significant components in understanding and assessing a company’s financial performance, such as a company’s cost of capital and tax structure, as well as the historic costs of depreciable assets, none of which are components of Adjusted EBITDAX. Our computations of Adjusted EBITDAX may not be comparable to other similarly titled measures of other companies. We believe that Adjusted EBITDAX is a widely followed measure of operating performance and may also be used by investors to measure our ability to meet debt service requirements.

The following table presents a reconciliation of the non-GAAP financial measure of Adjusted EBITDAX to the GAAP financial measure of net income (loss).

Supplemental Non-GAAP Financial Measure

(Unaudited)

Adjusted net income (loss) is a supplemental non-GAAP financial measure that is used by management and external users of our consolidated financial statements, such as industry analysts, investors, lenders and rating agencies. We define adjusted net income (loss) as net income (loss) before derivative fair value (gain) loss, excluding net cash receipts on settled derivative instruments incentive unit expense and other non-recurring items. Adjusted net income (loss) is not a measure of net income as determined by United States generally accepted accounting principles, or GAAP.

We believe that many investors use adjusted net income in making investment decisions and in evaluating our operational trends and our performance relative to other oil and gas producing companies.

The following table presents a reconciliation of the non-GAAP financial measure of adjusted net income (loss) to the GAAP financial measure of net income (loss).

Rice Energy Inc.

Supplemental Non-GAAP Financial Measure

(Unaudited)

PV-10 is a supplemental non-GAAP financial measure and generally differs from standardized measure, the mist directly comparable GAAP financial measure, because it does not include the effects of income taxes on future net revenues. PV-10 reflects the estimated future gross revenue to be generated from the production of proved reserves, net of estimated production, future development and abandonment costs, using prices and costs in effect at the determination date, before income taxes, and without giving effect to non-property-related expenses, discounted to a present value using an annual discount rate of 10% in accordance with the guidelines of the SEC. We and others in the industry use PV-10 as a measure to compare the relative size and value of proved reserves held by companies without regard to the specific tax characteristics of such entities. Neither PV-10 nor standardized measure represents an estimate of the fair market value of our natural gas properties.

The following table presents a reconciliation of the non-GAAP financial measure of PV-10 to the standardized measure of discounted future net cash flows:
