NATIONAL FUEL REPORTS SECOND QUARTER EARNINGS

Williamsville, New York: National Fuel Gas Company (“National Fuel” or the “Company”) (NYSE:NFG) today announced consolidated earnings for the second quarter of fiscal 2011 and for the six months ended March 31, 2011.

HIGHLIGHTS

• Earnings for the second quarter were $115.6 million, or $1.38 per share, an increase of $35.2 million, or $0.41 per share, compared to the prior year’s second quarter earnings of $80.4 million, or $0.97 per share. The increased earnings are primarily due to a $31.4 million, or $0.38 per share, gain on the sale of Horizon Power Inc’s interest in certain entities that owned landfill gas electric generation assets. Higher earnings in the Exploration and Production and Energy Marketing segments also contributed to the increase.

• Compared to the prior year’s second quarter, total production of crude oil and natural gas increased approximately 6.4 billion cubic feet equivalent (“Bcfe”), or 54.7%, to 18.2 Bcfe. Appalachian production was 10.9 Bcfe for the quarter, an increase of 7.3 Bcfe or 203.5%. Production from the Marcellus Shale was 9.0 Bcfe for the quarter. The Company’s production forecast for the entire 2011 fiscal year has been narrowed to a range between 66 and 71 Bcfe. The previous forecast range had been between 64 and 71 Bcfe.

• On April 27, 2011, Seneca Resources Corporation (“Seneca”) completed the $70 million sale of its offshore Gulf of Mexico oil and natural gas properties. The sale had an effective date of January 1, 2011. The sale proceeds were applied against Seneca’s full cost pool and reduced capitalized costs. No gain or loss resulted from the transaction.

• The Company is updating its GAAP earnings guidance range for fiscal 2011 to a range of $2.83 to $2.98 per share. The previous earnings guidance had been a range between $2.70 to $2.95 per share. This guidance assumes flat NYMEX pricing of $4.00 per Million British Thermal Units (“MMBtu”) for natural gas and $80.00 per barrel (“Bbl”) for crude oil for unhedged production for the remainder of the fiscal year.

• A conference call is scheduled for Friday, May 6, 2011, at 11 a.m. Eastern Time.

MANAGEMENT COMMENTS

     David F. Smith, Chairman and Chief Executive Officer of National Fuel Gas Company, stated: “With a terrific first half of the fiscal year complete, our results continue to demonstrate the financial and operational strength of our core assets. The consistent performance of the regulated businesses, combined with strong production growth within the Exploration and Production segment, more than made up for the challenging natural gas price environment.

     “Seneca’s ongoing success resulted in remarkable production growth of more than 50 percent over the prior year. In the Marcellus Shale, we crossed a milestone of 100 MMcf per day of natural gas production in March, more than doubling our daily production rate from the end of fiscal year 2010. As we move along with the testing and development of new areas and strata in the basin, we look for future production growth to exceed our initial conservative projections.

     “Also, during the quarter we announced the sale of Seneca’s Gulf of Mexico offshore properties and we completed the sale of assets from our Horizon Power, Inc. subsidiary, the last of our non-core businesses. Moving forward, we will be directing our resources and capital to our core assets and significant growth opportunities. With the ongoing build out of Appalachian pipeline infrastructure, significant production growth at Seneca, and dedication to safely and reliably serving our Utility customers, we will maintain our focus on the diversified, yet integrated business model and the value it creates for our shareholders.”

SUMMARY OF RESULTS

     National Fuel had consolidated earnings for the quarter ended March 31, 2011, of $115.6 million or $1.38 per share, compared to the prior year’s second quarter earnings of $80.4 million, or $0.97 per share, an increase of $35.2 million or $0.41 per share. (Note: all references to earnings per share are to diluted earnings per share, all amounts are stated in U.S. dollars, and all amounts used in the discussion of earnings and operating results before items impacting comparability (“Operating Results”) are after tax, unless otherwise noted.)

     Consolidated earnings for the six months ended March 31, 2011, of $174.2 million, or $2.08 per share, increased $29.2 million, or $0.32 per share, from the same period in the prior year, where earnings were $144.9 million or $1.76 per share.

     As outlined in the table above, certain items included in GAAP earnings impacted the comparability of the Company’s financial results when comparing the quarter and six months ended March 31, 2011, to the comparable periods in fiscal 2010. Excluding these items, Operating Results for the current quarter of $84.2 million, or $1.00 per share, increased $4.3 million, or $0.04 per share, from the prior year’s second quarter where Operating Results were $79.9 million or $0.96 per share. Excluding these items, Operating Results for the six months ended March 31, 2011, of $142.7 million, or $1.70 per share, decreased $1.4 million, or $0.05 per share, from the same period in the prior year, where Operating Results were $144.1 million or $1.75 per share. Items impacting comparability will be discussed in more detail within the discussion of segment earnings below.

DISCUSSION OF RESULTS BY SEGMENT

     (The following discussion of earnings for each segment is summarized in a tabular form at pages 10 through 13 of this report. It may be helpful to refer to those tables while reviewing this discussion.)

Exploration and Production Segment

     The Exploration and Production segment operations are carried out by Seneca Resources Corporation (“Seneca”). Seneca explores for, develops and produces natural gas and oil reserves in California and Appalachia. Seneca completed the sale of its Gulf of Mexico assets in April 2011.

     The Exploration and Production segment’s earnings in the second quarter of fiscal 2011 of $33.3 million, or $0.40 per share, increased $5.9 million, or $0.07 per share, when compared

with the prior year’s second quarter. The increase was mainly due to natural gas production that was 6.6 Bcf higher than the second quarter of fiscal 2010.

     Overall production of natural gas and crude oil for the current quarter of 18.2 Bcfe increased approximately 6.4 Bcfe, or 54.7 percent, compared to the prior year’s second quarter. Production increased 7.3 Bcfe, or 203.5 percent, in Appalachia due to higher production, mainly from Marcellus wells. Marcellus production was 9.0 Bcfe for the current quarter compared to 1.3 Bcfe in the second quarter of the prior year. In the Gulf of Mexico and California, production decreased approximately 20.9 percent and 3.7 percent, respectively. Both decreases were consistent with the normal decline rates expected in each region.

     Changes in commodity prices realized after hedging also impacted earnings. The weighted average natural gas price received by Seneca (after hedging) for the quarter ended March 31, 2011, was $5.32 per thousand cubic feet (“Mcf”), a decrease of $1.22 per Mcf. Higher crude oil prices realized after hedging contributed to the increase in earnings. The weighted average crude oil price received by Seneca (after hedging) for the quarter ended March 31, 2011, was $82.28 per Bbl, an increase of $4.99 per Bbl.

     Depletion, lease operating and general and administrative (“G&A”) expenses for the current year’s second quarter increased due to the higher production activity discussed above. However, on a per unit basis, lease operating and G&A expenses were down by $0.29 per thousand cubic feet equivalent (“Mcfe”) and $0.05 per Mcfe, respectively. Depletion was unchanged from last year’s quarter.

     The Exploration and Production segment’s earnings of $60.7 million, or $0.73 per share, for the six months ended March 31, 2011, increased $3.5 million, or $0.04 per share, when compared with the six months ended March 31, 2010. The increase was primarily due to natural gas production that was 11.2 Bcf higher than the prior year’s six-month period.

     Overall production for the six months ended March 31, 2011, increased approximately 45.3 percent to 33.9 Bcfe, an increase of 10.6 Bcfe, compared to the prior year’s six-month period. Production in Appalachia increased 194.8 percent to 19.1 Bcfe mainly due to the growth in production from the Marcellus which reached 14.9 Bcfe for the six-month period. In the Gulf of Mexico and California, production decreased approximately 23.5 percent and 4.2 percent, respectively. Both decreases were consistent with the normal decline rates expected in each region.

     Changes in commodity prices realized after hedging also impacted earnings. The weighted average natural gas price received by Seneca (after hedging) for the six-month period ended March 31, 2011, was $5.30 per Mcf, a decrease of $1.12 per Mcf. Higher crude oil prices realized after hedging contributed to the increase in earnings. The weighted average crude oil price received by Seneca (after hedging) for the six-month period ended March 31, 2011, was $79.21 per Bbl, an increase of $3.35 per Bbl.

     Depletion, lease operating and G&A expenses for the six months ended March 31, 2011 increased compared to the prior year’s six-month period due to the higher production activity discussed above. However, on a per unit basis, lease operating and G&A expenses were down

Page 5.

by $0.13 per Mcfe and $0.03 per Mcfe, respectively. Depletion increased $0.03 per Mcfe from last year’s six-month period.

Pipeline and Storage Segment

     The Pipeline and Storage segment operations are carried out by National Fuel Gas Supply Corporation (“Supply Corporation”) and Empire Pipeline, Inc. (“Empire”). The Pipeline and Storage segment provides natural gas transportation and storage services to affiliated and non-affiliated companies through an integrated system of pipelines and underground natural gas storage fields in western New York and western Pennsylvania.

     The Pipeline and Storage segment’s earnings of $11.0 million, or $0.13 per share, for the quarter ended March 31, 2011, decreased $1.5 million, or $0.02 per share, when compared with the same period in the prior fiscal year. The decrease was mostly due to increased operating expenses. Although more volumes of natural gas were transported for shippers under their firm transportation contracts, transportation revenues for both Supply Corporation and Empire were lower in the current quarter compared to the second quarter of 2010. Persistent strong Niagara/Chippawa basis prices have caused shippers to evaluate lower cost supply sources, and certain shippers have reduced their imports of natural gas from Canada. This has resulted in some contract terminations on Supply Corporation from Niagara. In order to offset these lower shipping volumes, Supply Corporation’s Northern Access expansion project and Empire’s Tioga County Extension Project have been designed to utilize that available capacity to provide producers of Marcellus gas a transportation path from the Marcellus supply basins to Canadian and other northeastern markets.

     The Pipeline and Storage segment’s earnings of $19.5 million, or $0.23 per share, for the six months ended March 31, 2011, decreased $3.3 million, or $0.05 per share, when compared with the six months ended March 31, 2010. The decrease in earnings for the current six-month period was due to higher operating expenses. Again, even though volumes shipped under customers’ firm contracts were higher, transportation revenues for both Supply Corporation and Empire were lower in the current six-month period compared to the same period in the prior fiscal year for the same reasons as described above.

Utility Segment

     The Utility segment operations are carried out by National Fuel Gas Distribution Corporation, which sells or transports natural gas to customers located in western New York and northwestern Pennsylvania.

     The Utility segment’s earnings of $33.1 million, or $0.40 per share, for the quarter ended March 31, 2011, decreased $0.2 million, or less than $0.01 per share, when compared with the same period in the prior fiscal year. The positive impact on earnings of colder weather and higher customer usage in Pennsylvania was more than offset by a New York regulatory adjustment regarding the timing of collection of certain regulatory expenses. In New York, colder weather did not have a significant impact on earnings for the quarter. The impact of weather variations on earnings in New York is mitigated by that jurisdiction’s weather normalization clause. Higher property taxes in both New York and Pennsylvania and higher income taxes in Pennsylvania also reduced earnings for the current second quarter.

     The Utility segment’s earnings of $56.1 million, or $0.67 per share, for the six months ended March 31, 2011, decreased from earnings of $56.3 million, or $0.68 per share, for the six months ended March 31, 2010. Colder weather and higher customer usage in Pennsylvania was more than offset by the impact of the New York regulatory adjustment, higher property taxes and income taxes discussed above. In addition, higher operating expenses and depreciation expense during the current six month period decreased earnings.

Energy Marketing Segment

     National Fuel Resources, Inc. (“NFR”) comprises the Company’s Energy Marketing segment. NFR markets natural gas to industrial, wholesale, commercial, public authority and residential customers primarily in western and central New York and northwestern Pennsylvania, offering competitively priced natural gas to its customers.

     The Energy Marketing segment’s earnings for the quarter ended March 31, 2011, of $6.3 million increased $0.3 million compared to the second quarter of the prior year due to higher volumes sold to retail customers and improved average margins per Mcf. Earnings for the six months ended March 31, 2011 of $7.2 million increased $0.2 million compared to the prior year’s six-month period. The increase in earnings is due to higher volumes sold to retail customers and improved average margins per Mcf, partially offset by higher operating expenses.

Corporate and All Other

     The Corporate and All Other category includes the following active, wholly owned subsidiaries of the Company: National Fuel Gas Midstream Corporation (“Midstream”), formed to build, own and operate natural gas processing and pipeline gathering facilities in the Appalachian region; and Highland Forest Resources, Inc., a corporation that markets high quality hardwoods from Appalachian land holdings.

     Earnings in the Corporate and All Other category for the quarter ended March 31, 2011, were $32.0 million, an increase of $30.6 million compared to the prior year’s second quarter earnings of $1.4 million. The comparability of the results for the quarters ended March 31, 2011 and March 31, 2010, is impacted by the following items. In February 2011, Horizon Power, Inc. completed the sale of its interest in certain entities that owned landfill gas electric generation assets and recorded a gain of $31.4 million. On September 1, 2010, the Company completed the sale of its landfill gas operations. As a result of this transaction, the Company is presenting the landfill gas operations as discontinued operations. Earnings in the second quarter of fiscal 2010 include earnings from discontinued operations of $0.6 million.

     Excluding the items above, Operating Results in the Corporate and All Other category of $0.6 million in the current year second quarter decreased from Operating Results of $0.8 million in the prior year’s second quarter. Lower earnings from timber sales as a result of the sale of the sawmill operations and higher corporate operating expenses more than offset higher earnings from Midstream’s pipeline gathering and natural gas processing operations.

     Earnings in the Corporate and All Other category for the six months ended March 31, 2011, were $30.6 million, an increase of $29.0 million when compared to the earnings for the six

Page 7.

months ended March 31, 2010, of $1.6 million. The comparability of the results for the six months ended March 31, 2011, and the prior year’s Six Month period was impacted by the $31.4 million gain on the Horizon Power Inc. sale of its landfill gas electric generations assets and $0.8 million of income from discontinued operations as a result of the sale of the Company’s landfill gas operations as described above.

     Excluding these items, Operating Results of $0.8 million for the six-month period ended March 31, 2010, compared to a loss of $0.8 million in the current year six-month period. Lower income from unconsolidated subsidiaries (due to the sale of landfill gas electric generation assets described above) and lower earnings from timber sales more than offset higher earnings from Midstream’s pipeline gathering and natural gas processing operations.

Discontinued Operations

     Earnings from discontinued operations for the quarter and six months ended March 31, 2011, decreased $0.6 million and $0.8 million, respectively. The decrease is the result of the Company’s September 1, 2010, sale of its landfill gas operations.

EARNINGS GUIDANCE

     The Company is updating its earnings guidance for fiscal 2011 to reflect actual results for the six months ended March 31, 2011. The revised GAAP earnings range is $2.83 to $2.98 per share. The previous guidance range had been $2.70 to $2.95 per share. This includes oil and gas production for fiscal 2011 for the Exploration and Production segment in a range between 66 and 71 Bcfe, hedges currently in place, and NYMEX equivalent flat commodity pricing on non-hedged volumes exclusive of basis differential, of $4.00 per MMBtu for natural gas and $80.00 per Bbl for crude oil.

This sensitivity table is current as of May 5, 2011 and only considers revenue from the Exploration and Production segment’s crude oil and natural gas sales. This revenue is based upon pricing used in the Company’s earnings forecast. For its fiscal 2011 earnings forecast, the Company is utilizing flat NYMEX equivalent commodity pricing, exclusive of basis differential, of $4 per MMBtu for natural gas and $80 per Bbl for crude oil. The sensitivities will become obsolete with the passage of time, changes in Seneca’s production forecast, changes in basis differential, as additional hedging contracts are entered into, and with the settling of hedge contracts at their maturity.
