To Our Shareholders

National Fuel Gas Company, listed on the New York Stock Exchange, had another impressive year of share appreciation, increasing in value by $3.63, or 
8.6 percent during fi scal year 2009. 

Dear Shareholder,

Fiscal Year 2009 was another remarkable year for National Fuel. During one of the most volatile and uncertain business environments that the 

United States has endured, we recognized earnings of $100.7 million, even after the effects of a non-cash ceiling test impairment that reduced earnings 
by $108.2 million. Perhaps more importantly, we generated more than $609 million in cash fl ow from operating activities. These results were achieved 
while we maintained a strong balance sheet – with a 56 percent equity component – and held more than $400 million in cash and temporary cash 
investments at year end.

In June 2009, your Board of Directors increased the dividend for the 39th consecutive year, marking our 107th year of uninterrupted payments. 
Refl ecting the market’s recognition of our achievements, the Company’s stock provided shareholders a total return of 13 percent for the fi scal year. 
The calendar year ending December 31, 2009, was even better—our stock provided a total return of 65 percent to shareholders, comparing very 
favorably against a 25 percent total return in the S&P 500 Index, a 39 percent total return in the S&P Oil and Gas Exploration and Production Index, 

2

and a 21 percent total return in the S&P 400 Utilities Index.

Marcellus Shale Wells Drilled Per Year

In 2009, National Fuel achieved a fourth place ranking in the  
annual Public Utilities Fortnightly list of Best Energy Companies. 
National Fuel has been listed in the Fortnightly top 40 list since its 
inception five years ago, and among the top 10 in each of the last  
four years. The metrics utilized by Fortnightly to determine a 
company’s rank include four-year averages of profit margin, dividend 
yield, free cash flow, return on assets and sustainable growth. These 
are areas where we have performed well for many years,  
thanks in large part to our diversified, integrated business model.

In addition to our overall financial performance, we are justly proud 
of the Company’s operational achievements in 2009. Our record shows 
once again that your Company’s words translate to actions. 

In our Exploration and Production segment, comprised of Seneca 

Resources Corporation, total production for 2009 was 42.5 billion 
cubic feet equivalent (Bcfe), an increase of four percent over the prior 
year. We replaced 160 percent of Seneca’s total production and had 
a net increase of more than 25 Bcfe of reserves. These results were 
achieved largely through our efforts in Appalachia, where we  
replaced an impressive 341 percent of production, and added 
proved reserves in the Marcellus Shale at an average finding and  
development cost of $1.28 per thousand cubic feet, excluding the  
cost of lease acquisitions.

Hydraulic fracturing is a process used to stimulate the flow of natural  
gas from the rock formations where the gas is located. Here, microseismic 
monitoring is used to measure the orientation and effectiveness of a 
hydraulic fracture in one of Seneca’s Marcellus wells.

Seneca’s Marcellus Shale drilling program began in 2006 through a 
joint venture with EOG Resources, who acts as operator on a portion 
of Seneca’s acreage. This year, Seneca began its own Marcellus drilling 
program and Seneca’s first independently operated well flowed at an 
average rate of nearly six million cubic feet per day for the first week 
of production, and its most recent well recorded a rate of nearly 10 
million cubic feet per day over its first week. As of the date of this 
letter, we have participated, through the EOG joint venture and in our 
own program, in the drilling of 24 horizontal wells in the Marcellus, 
including eight operated by Seneca. Since initiating this program 
Seneca has doubled its staff of geologists, engineers and industry

experts, and has achieved operating results equivalent to best-in-class 
peers. Based on our activity to date, we estimate there is between four 
and eight trillion cubic feet of risked resource potential in our 720,000 
net acres of mineral rights in the Marcellus Shale, the vast majority of 
which we own outright.

We benefited from the diversity among our Exploration and 
Production assets, as our California oil producing properties helped 
temper the steep decline in natural gas prices that occurred during 
the course of the year. To add to our position in California, we made 
a $34.9 million “bolt-on” acquisition, and we expect next year to once 
again increase production from the region.

In the Pipeline and Storage segment, we enhanced our focus in 

Appalachia by adding new transportation and storage contracts 

National Fuel Gas Midstream Corporation began construction on the 
Covington Gathering System in July 2009. The System, located in Tioga 
County, Pennsylvania, began flowing gas on November 17, 2009, and  
serves natural gas producers in the region, including Seneca, with a  
design capacity of 100 million cubic feet per day.

and completing several infrastructure projects. We also made 
progress identifying and pursuing interested shippers for our 
previously announced West-to-East Pipeline Project, including the 
Appalachian Lateral. 

The Utility remains an important part of our integrated model, 
and was the largest contributor to GAAP earnings during the fiscal 
year. Given its low growth due to economic conditions and customer 
conservation, the Utility continued its focus on cost containment, and 
we were able to reduce operation and maintenance expense for the 
fourth consecutive year. Notably, we achieved these significant savings 
while maintaining our consistently high levels of safety and customer 

The Clarion River in Pennsylvania, and its surrounding terrain, is an area 
that is prospective for the Marcellus Shale. Over the next two years, the 
Company plans to spend up to $550 million to continue the environmentally 
responsible development of our 720,000 Marcellus Shale acres.

For 2010 we will aggressively build  
upon our success in Appalachia. We 
look to make more than 85 percent 
of the Exploration and Production 
investment in Appalachia.

service. We are also proud of our very successful efforts in assisting 
customers to secure $73 million of heating assistance through the 
federal Home Energy Assistance Program. In the Utility, we intend to 
continue our long history of providing exceptional customer service, 
controlling costs and filing rate cases only when absolutely necessary.
Your Company’s approach to business opportunities has long been 

guided by what I believe to be a healthy dose of pragmatism. It is 
because of this approach that National Fuel has not merely survived, 
but has continued to grow and thrive. We size up opportunities 
with the long view and announce projections with respect to those 
opportunities only when we believe that those projections can be 
actually achieved. Right now, I am happy to report that your Company 
is presented with more and greater opportunities than possibly ever 
before in its history. For this reason, while it is gratifying to recount the 
outstanding year that recently concluded, it is more important to talk 
about the future, and how we plan to address opportunities in ways 
that will serve your Company’s best interests over the long run.

In 2010, we will aggressively build upon our success in Appalachia. 

Three years ago, we spent more than 70 percent of our Exploration 
and Production capital in Canada and the Gulf of Mexico. Since then, 
we sold our Canadian assets and have continued to trend away from 
significant new investment in the Gulf of Mexico. In 2010, we expect 
to allocate more than 85 percent of our Exploration and Production 
investment to Appalachia.

Our emphasis on Appalachia is most pronounced in the Marcellus 

Shale, where we look forward to significant production growth. For 
fiscal 2010, current plans call for the allocation of $200 million toward 
Marcellus Shale development, our participation in 55-75 wells, and

net production to Seneca of 30 to 50 million cubic feet per day at 
the end of the year. In 2011, we estimate $350 million of investment 
towards Marcellus development, up to 130 wells being drilled, and a 
net production rate of 60 to 100 million cubic feet per day at the end 
of the year. This activity supports our expectation of double-digit 
production increases. 

In our Pipeline and Storage segment, we are poised to grow 
the business with more than one billion dekatherms per day of 
transportation projects in various stages of development. Our

geographic advantage is more evident than ever, as we continue to 
identify opportunities with Seneca and third party producers looking 
for transportation services from emerging and established production 
areas to the markets where that gas is consumed. We anticipate that 
as much as $500 million could be spent in this segment over the next 
three years.

I am also pleased to report that we have made substantial progress 

gathering facilities primarily to bring Seneca’s growing Appalachian 
production to market. In November 2009, Midstream completed a 
gathering system to collect and move Seneca’s Marcellus production 
from Tioga County, Pennsylvania to Tennessee Gas Pipeline. Looking 
ahead, Midstream is considering more than a dozen projects to serve 
Seneca and other producers in Appalachia.

These and other potential projects reflect National Fuel’s flexible, 
yet evolving business model. Although nearly $2 billion of potential 
investment in Appalachia by our Exploration and Production and 
Pipeline and Storage segments will shift the balance of capital 
among our operating segments, the basic tenet of our model will 
remain intact. We have long believed and continue to believe, that 
the diversity of our business segments, providing synergies and a 
natural hedge, serves our shareholders and customers well. We are 
not, however, wedded to a static balance of investments among the 
segments, or any preordained allocation of capital, as an end unto 
itself. Rather, we will make investments where the opportunities are 
greatest, and right now and likely for the foreseeable future, those 
opportunities are in Appalachia. It nonetheless remains the Company’s 
objective that each segment continue to make a meaningful 
contribution to the whole, assuring that the diversified model that has 
distinguished National Fuel from its peers will continue to provide the 
same benefits going forward.

fund that activity. In fact, we expect to maintain a strong balance sheet 
over the next three years with our equity component ranging between 
50 and 60 percent. We believe that this is achievable based in large 
part on cash fl ow projections for Seneca.

Nationally, 2009 was a year of signifi cant change in the energy 

sector. We witnessed developments in federal and state laws, 
including an effort for broad energy legislation and other initiatives 
designed to decrease the nation’s usage of, and reliance on, fossil 
fuels. We support the effi cient and intelligent use of natural gas, and 
believe that conservation programs are a wise and necessary part of 
the overall energy solution. We disagree, however, with the notion 
advocated by some, that natural gas is indistinguishable, for purposes 
of environmental legislation, from other fossil fuels. Different fossil 
fuels have widely varying environmental impacts. Natural gas is the 
cleanest burning of all the fossil fuels, with approximately one-half of 
the carbon emissions of coal. In addition, the natural gas industry has

environment. In our Marcellus Shale drilling program, Seneca plans to

a long record of using low-impact, environmentally sound extraction 
technologies. New legislation should recognize these established 
benefi ts, as well as the fact that natural gas production will mean 
new jobs and prosperity in production areas that are in need of 
economic revitalization. 

Increased production and utilization of natural gas would also help 

to improve the nation’s energy security. Perhaps the single greatest 
development regarding natural gas, and a game-changer in my opinion, 
is the recognition of its vast abundance as a recoverable fuel. For 
decades, natural gas was considered to be a fuel source that was 
both scarce and depleting, and therefore an unsuitable choice for the 
nation’s long-term energy needs, particularly in electric generation 
markets. That mindset resulted in policies and practices which, for 
many years, favored coal over natural gas. The lingering effect of 
this long-held belief remains an impediment that, to this day, risks 
legislative decisions that are contrary to sound public policy. We will 
continue to work with our industry partners and advocacy groups 
to deliver the message that natural gas is the best energy choice 
for addressing the nation’s current and long term energy security, 
economic and environmental needs.

In 2009, there were a few notable changes in Management at 

National Fuel. Mike Kasprzak and Michael Colpoys were both 
promoted to the positions of Assistant Vice President, at National 
Fuel Gas Supply Corporation and National Fuel Gas Distribution 
Corporation, respectively. Mike Kasprzak has been with the Company 
for 28 years, concentrating on work in Compression Services, Supply 
Field Operations and Distribution Operations, most recently overseeing 
the installation of the Oakfi eld compressor station as part of the 
Empire Connector project. Michael Colpoys has worked at National 
Fuel for 22 years, in various positions in Pennsylvania Distribution and 
Supply Operations. Both will be dedicating their considerable expertise 
to the management of our regulated businesses and the development 
of expansion projects.

of people who have built an institution that refl ects shared values of

enabled the Company to generate extraordinary shareholder value and 
customer service again in 2009.

In last year’s Annual Report, I closed my letter with a statement 
of confi dence that the Company would maintain a steady course 
through a period of diffi cult economic times. That, indeed, is exactly 
what we did. As we close out another year of uncertainty and 
turbulence in the economy, I can again state with confi dence that 
your Company is well positioned for success not only in 2010, but also 
for the long run. Although this Company is undoubtedly in a period 
of change – albeit positive change – the value proposition we offer 
to shareholders remains simple and constant. We are a company 
backed by real, tangible assets in the form of proven reserves, pipelines 
serving growing markets, and distribution facilities serving hundreds of 
thousands of retail customers. We are also a company with signifi cant 
opportunities, and the ability, motivation and expertise to turn those 
opportunities into achievements. It is for all of these reasons that I look 
forward to the coming year and National Fuel’s continued success.

Exploration & Production

In July 2009, Seneca Resources purchased Ivanhoe Energy’s U.S.-based operations, predominantly oil producing properties, in the Midway Sunset Field in California. 
This “bolt-on” acquisition immediately added approximately 600 net barrels per day of production to Seneca’s West Division, while requiring the addition of
only one employee. 

Seneca Resources Corporation, our Exploration & Production subsidiary, had one of its best operating years in history, replacing 160 percent of 

production and adding a net 25 billion cubic feet equivalent of reserves. In addition, total production increased four percent to 42.5 Bcfe. Most 
importantly, Seneca made signifi cant progress in the development of its enormous resource potential in the Marcellus Shale. 

Despite the higher production, Seneca posted a loss of $10.2 million compared to earnings for the prior year of $146.6 million. The decrease in 
earnings was largely related to a non-cash ceiling test impairment charge of $108.2 million in the fi rst quarter of the fi scal year, primarily the result of 
signifi cant decreases in crude oil and natural gas prices.

Capital expenditures and investments in subsidiaries in the Exploration & Production segment increased to $223 million for fi scal year 2009, with
more than 60 percent of this spending in Appalachia. Seneca made two large investments during the fi scal year. The fi rst was the leasing of Pennsylvania 
acreage in Tioga and Lycoming Counties prospective for the Marcellus Shale, and the second was a “bolt-on” addition to our oil producing properties 
in California. In fi scal year 2010, total capital devoted to Exploration & Production is expected to be approximately $255 million, including further 
development in Appalachia, which will receive more than 85 percent of this capital.

The Marcellus Shale is the focus of our development efforts as we move forward with an increasingly aggressive plan for our 720,000 net 

prospective acres. Seneca initiated its independently operated drilling program in the Marcellus Shale in March 2009. To date, 11 vertical wells have 
been drilled across seven counties in Pennsylvania, and conventional core samples have been taken in order to prioritize our acreage for development. 

8

Seneca has also drilled eight horizontal wells, to date, in the 

Domestic Extensions and Discoveries (MMcfe)

Marcellus Shale under its independent program. Three of these wells 
were completed and fl owed at a seven-day combined rate of more 
than 20 million cubic feet per day. In addition to the Seneca-operated 
activity, we continued to participate with our joint venture partner, 
EOG Resources, in a total of 16 horizontal wells. Seneca plans to drill 
between 25 to 35 horizontal wells in fi scal year 2010, with the help of 
a second horizontal drilling rig that arrived on-site in November 2009. 
By the end of 2010, we plan to have identifi ed two to three additional 
focus areas for developmental drilling. EOG operates two rigs in the 
Marcellus Shale and will drill approximately 25 to 35 horizontal wells 
for the joint venture in fi scal year 2010.

With data acquired during the past year, we were able to estimate 

our risked resource potential in the Marcellus Shale play at four to 
eight trillion cubic feet. This estimate is based on 100-acre spacing and 
ultimately producing two to three billion cubic feet per well drilled 
on 30 to 40 percent of our acreage position. In 2009, we added 21.2 
billion cubic feet of Marcellus Shale reserves at an average fi nding and 
development cost of $1.28 per thousand cubic feet, excluding the cost 
of lease acquisition. Assuming that our escalated activity continues 
as planned, we now anticipate production rates from the Marcellus 
Shale of 30 to 50 million cubic feet per day by September 30, 2010, 
and 60 to 100 million cubic feet per day one year later, net to Seneca. 

Once a Marcellus well is completed and ready to produce gas, the well 
site leaves minimal impact on the environment. The original drill site is 
restored to a natural condition and the production facilities occupy a 
very small area. 

With an expected drilling inventory of 3,000 to 4,000 gross wells in 
the Marcellus Shale, this will be an area of continued expansion, with 
capital spending of $200 million and $350 million currently budgeted 
for fi scal years 2010 and 2011, respectively.

In our Upper Devonian conventional drilling program in Appalachia, 
we continued to make strong progress, with our third consecutive year 
of production increases. We drilled 195 wells in fi scal 2009, and expect 
to drill approximately 150 wells in fi scal 2010. 

In California, we were able to increase oil production for the second 
consecutive year, and continued our status as a low-cost operator. The 
West Division was also an important contributor to earnings, as the 
price of oil remained relatively strong compared to the price of natural 
gas in 2009. In July 2009, we completed the purchase of Ivanhoe 
Energy’s U.S. oil and gas properties, predominantly in the Midway

Sunset Field. After closing adjustments, we paid $34.9 million for 2.2 
million barrels of proved reserves, or approximately $16 per barrel. 

Although the Gulf of Mexico is an area we continue to de-emphasize, 
in July 2009, these assets produced 50 million cubic feet equivalent per 
day, their highest rate in more than four years. For fi scal year 2010, with 
minimal capital spending, we expect production of 11 to 13 billion cubic 
feet equivalent.

In summary, we anticipate total Seneca production in fi scal 2010 to be 
in the range of 42 to 50 billion cubic feet equivalent, approximately eight 
percent higher than fi scal year 2009 at the midpoint of the range. As we 
continue to accelerate our Marcellus development, we are expecting 
overall production increases of approximately 20 percent per year in 
fi scal years 2011 and 2012, with continued growth for many years beyond.

Since Seneca initiated its independent drilling program in March 2009, it has 
drilled and completed three wells in Tioga County, Pennsylvania, the most 
recent of which produced more than 10 MMcf of natural gas in its fi rst day. 
This picture shows the rig that completed this drilling, and with the help of 
a second rig that arrived in November 2009, Seneca plans to independently 
drill another 25-35 horizontal wells in fi scal 2010.

Pipeline & Storage

Supply plans to seek regulatory approval to replace and relocate the Line N natural gas pipeline and construct a compressor station in Pennsylvania, in Greene
and Washington Counties. This project will help improve the reliability and increase the capacity of the existing pipeline system, which transports natural gas
 from Appalachia to markets in western Pennsylvania and throughout the northeast. This project has an anticipated in-service date of November 2011.

The Pipeline & Storage segment posted earnings of $47.4 million in fi scal year 2009. Transportation revenues increased as a result of new fi rm 
transportation contracts in Appalachia, where we have focused our efforts, and because of revenues generated by the Empire Connector Pipeline that 
went into service in December 2008. These gains, however, were more than offset by higher interest and depreciation costs, a lower allowance for 
funds used during construction, and lower effi ciency gas revenues.

Going forward, we plan to continue our long-term investment strategy for this segment in order to maximize the natural advantage of our 
geographic location. Much of Empire Pipeline, Inc., and National Fuel Gas Supply Corporation’s transmission and storage assets are located in 
Appalachia, and our pipeline network overlays the Marcellus Shale. Successful development of the Marcellus Shale play – for Seneca and unaffi liated 
producers – will require signifi cant investment to assure market access for new production. We are very well positioned to satisfy the increased 
demand for pipeline and storage capacity with our existing and planned facilities. In fi scal year 2010, capital spending is estimated to be $51 million, 
and based on expansion opportunities, spending should increase signifi cantly in fi scal years 2011 and 2012 as a number of projects are developed.

Our objective remains to further capitalize on the synergies 

presented by National Fuel’s diversifi ed model. Perhaps nowhere else in 
our business are those synergies better exemplifi ed than in the Pipeline 
& Storage segment’s location of assets across a wide area prospective 
for the Marcellus Shale. The projects described above were conceived 
as opportunities arising from this segment’s locational advantage, and 
today those opportunities are under development. With more than 
one billion dekatherms per day of transportation and storage projects 
in various stages of development, the Pipeline & Storage segment will 
continue to be integral to National Fuel’s long-term growth.

Supply employees plan and implement projects to expand our system
and maximize our geographic advantage in the heart of Appalachia and the 
Marcellus play. Pictured here (left to right) are: Jeff Kittka, General Manager 
of Engineering Services; Ron Kraemer, Vice President; and Mike Kasprzak, 
Assistant Vice President. 

The planned West-to-East (W2E) Project, with its companion 
Appalachian Lateral, is the largest of our infrastructure projects 
proposed in Appalachia. This project is under way and, given its 
signifi cant scope, is progressing in stages. In October 2009, we 
concluded a binding Open Season for Phases I and II of the W2E/
Appalachian Lateral, aimed at moving Marcellus Shale production 
from various counties in central Pennsylvania to the Leidy Hub, an 
interstate pipeline interconnect providing access to eastern markets. 
W2E/Appalachian Lateral has attracted a signifi cant amount of 
interest, and our marketing team is currently working with bidders 
and other interested parties to fi nalize agreements supporting 
construction of the facilities.

Supply is also preparing a Federal Energy Regulatory Commission 

certifi cate fi ling for its Line N Expansion Project. Backed by a key 
Marcellus Shale producer in southwestern Pennsylvania, this expansion 
will provide incremental transportation of 150,000 dekatherms per day 
to the point furthest south on Supply’s system, an interconnect with 
Texas Eastern Transmission in Holbrook, Pennsylvania. It is anticipated 
that this expansion will be in service in November 2011.

One of the more imminent projects that we hope to have in service 
as early as May 2010, is the addition of incremental compression at the 
Lamont Station on Supply’s system. This $6 million, 1,200 horsepower 
expansion will allow for 40,000 dekatherms per day of incremental

third-party producers to market.

delivery capacity from Elk and Cameron Counties, Pennsylvania, to 
Supply’s interconnection with Tennessee Gas Pipeline’s interstate 
pipeline facilities.

Empire conducted an Open Season for the Tioga County Extension, 
a project that will transport Marcellus Shale production from Tioga 
County, Pennsylvania to the Millennium Pipeline, the Chippawa, 
Ontario, interconnect with TransCanada Pipeline, and a newly proposed 
interconnect with Tennessee Gas Pipeline in Ontario County, New York. 
This 16-mile extension has a projected in-service date of September 
2011, and is designed to transport at least 200,000 dekatherms per day.

Utility

Our Utility segment has provided safe and reliable service to customers in western New York and northwestern Pennsylvania for more than 100 years. 
Here, the Utility replaces a 16” pipeline on South Park Avenue in Buffalo, New York.

National Fuel Gas Distribution Corporation posted earnings of $58.7 million, a decrease of $2.8 million compared to the previous year. This decrease 

was the result of higher interest expense, lower normalized usage per account in our Pennsylvania jurisdiction, the negative impact of a rate design 
change in New York, and higher effective income tax expense. These negative effects were minimized, however, by a reduction in operating expenses 
of $3.5 million and colder than normal weather in Pennsylvania.

In our New York service territory, fi scal year earnings were $37.7 million, a decrease of $3 million compared to the previous year. This was primarily 
the result of a rate design change, effective in December 2007. For 2009, this meant that revenues early in the year were down compared to the same 
period in the prior year. Prospectively, this rate design change will help stabilize monthly customer bills and minimize spikes during the heating season. 
Higher interest expense also contributed to the decrease, which was partially offset by lower operating expenses.

12

In Pennsylvania, earnings were $21 million, an increase of $0.2 
million compared to the previous year. Although the Pennsylvania 
Division experienced an increase in interest expense, as mentioned 
above for New York, and experienced a decrease in normalized usage 
per account, the resulting effect on earnings was more than offset by 
reduced operating expenses and colder weather.

Given its limited growth opportunities, the Utility segment has long 
focused on controlling costs in order to achieve its allowed return on 
rate base. Indeed, the Utility segment’s dedicated and capable work 
force has reduced costs for four consecutive years. And while cost 
control is clearly an ongoing effort, it has not diminished the Utility’s 
continued emphasis on safety and quality of service. During fi scal year 
2009, we spent $56.2 million on system upgrades, to ensure that our 
pipeline network continues to operate safely and reliably. We also 
closely monitor telephone response time, customer service and our 
ability to quickly respond to emergency issues, exceeding performance 
metrics set by regulators.

Going forward, the Utility faces several challenges. Conservation and 

effi ciency programs continue to capture the attention of regulators 
and customers. In New York, our successful Conservation Incentive 
Program (CIP) has commenced its third year. Through the CIP rebates 
and other incentives, thousands of New York customers have installed 
new, energy effi cient appliances and undertaken other conservation

Wheels for Western New York, pictured here, received a 2009 grant from 
the New York Utility Division’s Area Development Program.

measures that will help to drive down their energy costs over the 
long run. We continue to support the CIP and other effective energy 
effi ciency initiatives in New York because we have long advocated for 
the effi cient use of natural gas, and further because of the protection 
afforded the New York Division by a revenue decoupling mechanism. 
Although Pennsylvania has not yet adopted a revenue decoupling 
mechanism, together with other utilities we continue to press for its 
approval so that the interests of the Utility and its customers can be 
aligned in the pursuit of benefi cial energy conservation objectives.

A particular challenge in the current economic downturn will be 

managing our aged accounts receivable balance. Toward that end, 
to help customers pay their gas bills, we will continue our efforts, in

collaboration with government agencies, to ensure that robust federal 
assistance is allocated to our service territories and distributed to 
qualifi ed customers.

Finally, the effects of a sluggish economy and increased customer 

conservation efforts will require us to closely monitor the need to 
fi le rate cases. Most major utilities in New York and Pennsylvania 
have found it necessary to seek rate relief in the past two years, in 
some cases more than once. Largely because of our aggressive cost 
containment practices, we have managed to avoid the need to fi le a 
rate case since 2006 in Pennsylvania, and 2007 in New York. As a result, 
our customers have experienced the benefi t of stable delivery charges. 
We expect to continue the same cost containment practices for 
2010 in an effort to hold the line on rates while meeting our earnings 
objectives, and without compromising safety and the high quality of 
service our customers expect.

With the help of a grant from the Utility’s research and development program, 
Clarion University of Pennsylvania established an advanced energy laboratory 
in its new Science & Technology Center. The National Fuel Energy Laboratory 
features a hybrid electric generation system that incorporates the synergies 
of a 65-kilowatt microturbine with solar panels producing supplemental 
electricity for use during high-load daytime periods. The microturbine, 
pictured here, generates electricity and heat from clean-burning natural gas.

Energy Marketing

NFR was chosen by the Amherst Chamber of Commerce to be its Premier Supplier of natural gas. Under the Premier Natural Gas Supplier Program, NFR offers its 
expertise and a membership discount in order to help businesses control their energy costs. Here, Bob Tullio, Sales Manager for NFR, discusses program benefi ts 
to Chamber members at the inaugural meeting. 

The Energy Marketing segment, comprised of National Fuel Resources, Inc. (NFR), earned $7.2 million in fi scal year 2009, an increase of $1.3 million 
when compared to earnings of $5.9 million in fi scal year 2008. The improved results were primarily because of an increase in margin driven by lower 
pipeline transportation fuel costs. This also refl ects improved average margin per thousand cubic feet and the non-recurrence of an unfavorable 
pipeline imbalance resolution that occurred in fi scal 2008. Higher pipeline reservation charges related to additional storage capacity partially offset 
these margin increases.

NFR continues to focus on steady growth based on competitive pricing, reliability, and strong customer service. Retail gas sales and certain 
incremental wholesale gas sales provided NFR with natural gas sales volume of 60.9 billion cubic feet, an increase of 4.7 billion cubic feet over the 
prior year. In addition to its solid footing as a market leader on National Fuel’s utility system, NFR maintained its strong off-system performance 
on the National Grid, Rochester Gas & Electric, and New York State Electric and Gas utility systems with sales of 6.5 billion cubic feet.

14

In a year of unprecedented economic turmoil, many of NFR’s 
commercial and industrial customers were seriously impacted by 
the downturn in the U.S. economy. Customer credit was a particular 
challenge. NFR was able to leverage its strengths in operations, sales 
and risk management to successfully respond to these challenges and 
fi nish the year with strong fi nancial results. Additionally, NFR’s key 
storage and transportation contracts enable it to operate in a fl exible, 
reliable and strategic fashion that few marketers are able to match.
From residential households to large industrial customers, NFR 
offers years of experience and competitively priced natural gas to 
its diverse customer base in the complex natural gas marketplace. 
Representing National Fuel’s deregulated retail end of the natural gas 
supply chain, NFR, as a major customer of both Supply and Empire, 
refl ects the synergies of the Company’s diversifi ed model.

Going forward, NFR will continue to develop and market innovative 

natural gas supply choices for existing and potential customers, and 
pursue growth on National Fuel’s utility system and in adjacent utility 
service territories.

Corporate and All Other

National Fuel’s other operating subsidiaries reported a loss of 
$2.2 million for fi scal year 2009, compared to net income of $0.6 
million for fi scal year 2008. The loss for fi scal year 2009 includes a 
$2.8 million loss related to an impairment of a landfi ll gas site and a 
$1.1 million loss related to an impairment of Energy Systems North 
East, a regional gas-fi red power production plant, following decreased 
utilization given the economic downturn and the resulting decrease 
in demand for electric power. 

In November 2009, National Fuel Gas Midstream Corporation 
completed its fi rst pipeline project, the Covington Gathering System. 
This project is designed to transport 100 million dekatherms of

Marcellus Shale natural gas production per day, to Tennessee Gas 
Pipeline. With the increased drilling activity in the Marcellus, we 
expect this will be an area of continued investment, with $45 
million, $20 million and $20 million in capital expenditures 
currently estimated in fi scal years 2010, 2011 and 2012, respectively.
Other operating activities include a Timber business, operated 
by Highland Forest Resources, Inc., and the Northeast Division of 
Seneca Resources, that owns two sawmills and markets high quality 
hardwoods from the 106,741 acres of timber properties that we either 
own or manage. Horizon LFG, Inc., engages in the purchase, sale and 
transportation of landfi ll gas in six Midwestern states, and Horizon 
Power, Inc., develops and operates mid-range independent power 
production facilities and electric generation facilities powered
by landfi ll gas.

Midstream spending over the next three years could total more than 
$85 million, as there are more than a dozen projects under consideration.

PART I

Item 1 Business

The Company and its Subsidiaries

National Fuel Gas Company (the Registrant), incorporated in 1902, is a holding company organized under
the laws of the State of New Jersey. Except as otherwise indicated below, the Registrant owns directly or
indirectly all of the outstanding securities of its subsidiaries. Reference to “the Company” in this report means
the Registrant, the Registrant and its subsidiaries or the Registrant’s subsidiaries as appropriate in the context of
the disclosure. Also, all references to a certain year in this report relate to the Company’s fiscal year ended
September 30 of that year unless otherwise noted.

The Company is a diversified energy company and reports financial results for four business segments.

1. The Utility segment operations are carried out by National Fuel Gas Distribution Corporation
(Distribution Corporation), a New York corporation. Distribution Corporation sells natural gas or provides
natural gas transportation services to approximately 727,000 customers through a local distribution system
located in western New York and northwestern Pennsylvania. The principal metropolitan areas served by
Distribution Corporation include Buffalo, Niagara Falls and Jamestown, New York and Erie and Sharon,
Pennsylvania.

2. The Pipeline and Storage segment operations are carried out by National Fuel Gas Supply Corporation
(Supply Corporation), a Pennsylvania corporation, and Empire Pipeline, Inc. (Empire), a New York corpo-
ration. Supply Corporation provides interstate natural gas transportation and storage services for affiliated and
nonaffiliated companies through (i) an integrated gas pipeline system extending from southwestern
Pennsylvania to the New York-Canadian border at the Niagara River and eastward to Ellisburg and Leidy,
Pennsylvania, and (ii) 27 underground natural gas storage fields owned and operated by Supply Corporation as
well as four other underground natural gas storage fields owned and operated jointly with other interstate gas
pipeline companies. Empire, an interstate pipeline company, transports natural gas for Distribution Corpo-
ration and for other utilities, large industrial customers and power producers in New York State. Empire owns
the Empire Pipeline, a 157-mile pipeline that extends from the United States/Canadian border at the Niagara
River near Buffalo, New York to near Syracuse, New York, and the Empire Connector, which is a 76-mile
pipeline extension from near Rochester, New York to an interconnection with the unaffiliated Millennium
Pipeline near Corning, New York. The Millennium Pipeline serves the New York City area. The Empire
Connector was placed into service on December 10, 2008.

3. The Exploration and Production segment operations are carried out by Seneca Resources Corporation
(Seneca), a Pennsylvania corporation. Seneca is engaged in the exploration for, and the development and
purchase of, natural gas and oil reserves in California, in the Appalachian region of the United States, and in the
Gulf Coast region of Texas and Louisiana, including offshore areas in federal waters and some state waters. At
September 30, 2009, the Company had U.S. proved developed and undeveloped reserves of 46,587 Mbbl of oil
and 248,954 MMcf of natural gas.

3

In 2007, Seneca sold its subsidiary, Seneca Energy Canada Inc. (SECI), which conducted exploration and

production operations in the provinces of Alberta, Saskatchewan and British Columbia in Canada.

4. The Energy Marketing segment operations are carried out by National Fuel Resources, Inc. (NFR), a
New York corporation, which 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 for its customers.

Financial information about each of the Company’s business segments can be found in Item 7, MD&A and

also in Item 8 at Note K — Business Segment Information.

The Company’s other direct wholly owned subsidiaries are not included in any of the four reported

business segments and include the following active companies:

(cid:129) Highland Forest Resources, Inc. (Highland), a New York corporation which, together with a division of
Seneca known as its Northeast Division, markets timber from New York and Pennsylvania land holdings,
owns two sawmills in northwestern Pennsylvania and processes timber consisting primarily of high
quality hardwoods. At September 30, 2009, the Company owned 103,317 acres of timber property and
managed an additional 3,424 acres of timber rights;

(cid:129) Horizon Energy Development, Inc. (Horizon), a New York corporation formed to engage in foreign and
domestic energy projects through investments as a sole or substantial owner in various business entities.
These entities include Horizon’s wholly owned subsidiary, Horizon Energy Holdings, Inc., a New York
corporation, which owns 100% of Horizon Energy Development B.V. (Horizon B.V.). Horizon B.V. is a
Dutch company that is in the process of winding up or selling certain power development projects in
Europe. In July 2005, Horizon B.V. sold its entire 85.16% interest in United Energy, a.s., a district heating
and electric generation business in the Czech Republic;

(cid:129) Horizon LFG, Inc. (Horizon LFG), a New York corporation engaged through subsidiaries in the
purchase, sale and transportation of landfill gas in Ohio, Michigan, Kentucky, Missouri, Maryland
and Indiana. Horizon LFG and one of its wholly owned subsidiaries own all of the partnership interests
in Toro Partners, LP (Toro), a limited partnership which owns and operates short-distance landfill gas
pipeline companies;

(cid:129) Horizon Power, Inc. (Horizon Power), a New York corporation which is an “exempt wholesale
generator” under PUHCA 2005 and is developing or operating mid-range independent power produc-
tion facilities and landfill gas electric generation facilities; and

(cid:129) National Fuel Gas Midstream Corporation (Midstream Corporation), a Pennsylvania corporation
formed to build, own and operate natural gas processing and pipeline gathering facilities in the
Appalachian region.

No single customer, or group of customers under common control, accounted for more than 10% of the

Company’s consolidated revenues in 2009.

Rates and Regulation

The Registrant is a holding company as defined under PUHCA 2005. PUHCA 2005 repealed PUHCA 1935,
to which the Company was formerly subject, and granted the FERC and state public utility commissions access
to certain books and records of companies in holding company systems. Pursuant to the FERC’s regulations
under PUHCA 2005, the Company and its subsidiaries are exempt from the FERC’s books and records
regulations under PUHCA 2005.

The Utility segment’s rates, services and other matters are regulated by the NYPSC with respect to services
provided within New York and by the PaPUC with respect to services provided within Pennsylvania. For
additional discussion of the Utility segment’s rates and regulation, see Item 7, MD&A under the heading “Rate
and Regulatory Matters” and Item 8 at Note A — Summary of Significant Accounting Policies (Regulatory
Mechanisms) and Note C — Regulatory Matters.

4

The Pipeline and Storage segment’s rates, services and other matters are regulated by the FERC. For
additional discussion of the Pipeline and Storage segment’s rates and regulation, see Item 7, MD&A under the
heading “Rate and Regulatory Matters” and Item 8 at Note A — Summary of Significant Accounting Policies
(Regulatory Mechanisms) and Note C — Regulatory Matters.

The discussion under Item 8 at Note C — Regulatory Matters includes a description of the regulatory assets
and liabilities reflected on the Company’s Consolidated Balance Sheets in accordance with applicable account-
ing standards. To the extent that the criteria set forth in such accounting standards are not met by the operations
of the Utility segment or the Pipeline and Storage segment, as the case may be, the related regulatory assets and
liabilities would be eliminated from the Company’s Consolidated Balance Sheets and such accounting treatment
would be discontinued.

In addition, the Company and its subsidiaries are subject to the same federal, state and local (including
foreign) regulations on various subjects, including environmental matters, to which other companies doing
similar business in the same locations are subject.

The Utility Segment

The Utility segment contributed approximately 58.3% of the Company’s 2009 net income available for

common stock.

Additional discussion of the Utility segment appears below in this Item 1 under the headings “Sources and
Availability of Raw Materials,” “Competition: The Utility Segment” and “Seasonality,” in Item 7, MD&A and in
Item 8, Financial Statements and Supplementary Data.

The Pipeline and Storage Segment

The Pipeline and Storage segment contributed approximately 47.0% of the Company’s 2009 net income

available for common stock.

Supply Corporation has year-to-year or longer service agreements for all of its firm storage capacity, totaling
68,408 MDth. The Utility segment has contracted for 27,865 MDth or 40.7% of the total firm storage capacity,
and the Energy Marketing segment accounts for another 4,811 MDth or 7.1% of the total firm storage capacity.
Nonaffiliated customers have contracted for the remaining 35,732 MDth or 52.2% of the total firm storage
capacity. The majority of Supply Corporation’s storage and transportation services are performed under
contracts that allow Supply Corporation or the shipper to terminate the contract upon six or twelve months’
notice effective at the end of the contract term. The contracts also typically include “evergreen” language
designed to allow the contracts to extend year-to-year at the end of the primary term. At the beginning of 2010,
82.9% of Supply Corporation’s total firm storage capacity was committed under contracts that, subject to 2009
shipper or Supply Corporation notifications, could have been terminated effective in 2010. Supply Corporation
did not issue or receive any such storage contract termination notifications in 2009. The strong demand for
market-area storage enabled Supply Corporation to provide all of its year-to-year or longer storage services in
2009 at the maximum tariff rates.

Supply Corporation’s firm transportation capacity is not a fixed quantity, due to the diverse web-like nature
of its pipeline system, and is subject to change as the market identifies different transportation paths and receipt/
delivery point combinations. Supply Corporation currently has firm transportation service agreements for
approximately 2,189 MDth per day (contracted transportation capacity). The Utility segment accounts for
approximately 1,065 MDth per day or 48.7% of contracted transportation capacity, and the Energy Marketing
and Exploration and Production segments represent another 112 MDth per day or 5.1% of contracted
transportation capacity. The remaining 1,012 MDth or 46.2% of contracted transportation capacity is subject
to firm contracts with nonaffiliated customers.

At the beginning of 2010, 52.7% of Supply Corporation’s contracted transportation capacity was com-
mitted under affiliate contracts that were scheduled to expire in 2010 or, subject to 2009 shipper or Supply
Corporation notifications, could have been terminated effective in 2010. Based on contract expirations and
termination notices received in 2009 for 2010 termination, and taking into account any known contract

5

additions, contracted transportation capacity with affiliates is expected to increase 3.0% in 2010. Similarly,
33.0% of contracted transportation capacity was committed under unaffiliated shipper contracts that were
scheduled to expire in 2010 or, subject to 2009 shipper or Supply Corporation notifications, could have been
terminated effective in 2010. Based on contract expirations and termination notices received in 2009 for 2010
termination, and taking into account any known contract additions, contracted transportation capacity with
unaffiliated shippers is expected to increase 5.3% in 2010. This increase is due largely to the addition of
compression at various facilities throughout the system as well as other projects designed to create incremental
transportation capacity. Supply Corporation previously has been successful in marketing and obtaining
executed contracts for available transportation capacity (at discounted rates when necessary), and expects
this success to continue.

For the 2009-2010 winter period, Empire has service agreements in place for firm transportation capacity
totaling approximately 689 MDth per day (including capacity on the new Empire Connector facilities discussed
below). Most of Empire’s firm contracted capacity (93.0%) has been contracted as long-term full-year deals. Two
of those contracts are due to expire during 2010, representing just 0.1% of Empire’s firm contracted capacity. In
addition, Empire has some seasonal (winter-only) contracts that extend for multiple years, representing 2.5% of
Empire’s firm contracted capacity. One of those seasonal contracts is due to expire during 2010, representing
just 0.1% of Empire’s firm contracted capacity. Arrangements for the remaining 4.5% of Empire’s firm contracted
capacity are single-season or single-year contracts that expire during 2010 or early in 2011. Empire expects that
all available capacity arising from expiring agreements will be re-contracted as seasonal or full-year agreements.
The Utility segment accounts for 6.1% of Empire’s firm contracted capacity, and the Energy Marketing segment
accounts for 1.2% of Empire’s firm contracted capacity, with the remaining 92.7% of Empire’s firm contracted
capacity subject to contracts with nonaffiliated customers.

Empire’s new facilities (the Empire Connector project) were placed into service on December 10, 2008.
Empire has a firm service agreement for 150.7 MDth per day of this expansion capacity. This long-term full-year
agreement represents approximately 60% of the Empire Connector’s total capacity. None of this contracted
capacity will expire during fiscal 2010.

Additional discussion of the Pipeline and Storage segment appears below under the headings “Sources and
Availability of Raw Materials,” “Competition: The Pipeline and Storage Segment” and “Seasonality,” in Item 7,
MD&A and in Item 8, Financial Statements and Supplementary Data.

The Exploration and Production Segment

The Exploration and Production segment incurred a net loss in 2009. The impact of this net loss in relation to
the Company’s 2009 net income available for common stock was negative 10.2%. The net loss in the Exploration
and Production segment was largely driven by an impairment charge of $182.8 million ($108.2 million after tax).

Additional discussion of the Exploration and Production segment appears below under the headings
“Discontinued Operations,” “Sources and Availability of Raw Materials” and “Competition: The Exploration
and Production Segment,” in Item 7, MD&A and in Item 8, Financial Statements and Supplementary Data.

The Energy Marketing Segment

The Energy Marketing segment contributed approximately 7.1% of the Company’s 2009 net income

available for common stock.

Additional discussion of the Energy Marketing segment appears below under the headings “Sources and
Availability of Raw Materials,” “Competition: The Energy Marketing Segment” and “Seasonality,” in Item 7,
MD&A and in Item 8, Financial Statements and Supplementary Data.

All Other Category and Corporate Operations

The All Other category and Corporate operations incurred a net loss in 2009. The impact of this net loss in

relation to the Company’s 2009 net income available for common stock was negative 2.2%.

Financial Statements and Supplementary Data.

Sources and Availability of Raw Materials

Natural gas is the principal raw material for the Utility segment. In 2009, the Utility segment purchased
76.8 Bcf of gas for delivery to its customers. All such purchases were made from non-affiliated companies. Gas
purchased from producers and suppliers in the southwestern United States and Canada under firm contracts
(seasonal and longer) accounted for 56% of these purchases. Purchases of gas under contracts for one month or
less accounted for 44% of the Utility segment’s 2009 purchases. Purchases from Total Gas & Power
North America Inc. (20%), Chevron Natural Gas (15%), BP Canada (14%) and ConocoPhillips Company
(12%) accounted for 61% of the Utility’s 2009 gas purchases. No other producer or supplier provided the Utility
segment with more than 10% of its gas requirements in 2009.

Supply Corporation transports and stores gas owned by its customers, whose gas originates in the
southwestern, mid-continent and Appalachian regions of the United States as well as in Canada. Empire
transports gas owned by its customers, whose gas originates in the southwestern and mid-continent regions of
the United States as well as in Canada. Additional discussion of proposed pipeline projects appears below under
“Competition: The Pipeline and Storage Segment” and in Item 7, MD&A.

The Exploration and Production segment seeks to discover and produce raw materials (natural gas, oil and
hydrocarbon liquids) as further described in this report in Item 7, MD&A and Item 8 at Note K — Business
Segment Information and Note Q — Supplementary Information for Oil and Gas Producing Activities.

The Energy Marketing segment depends on an adequate supply of natural gas to deliver to its customers. In
2009, this segment purchased 62.5 Bcf of gas, including 60.9 Bcf for delivery to its customers. The remaining
1.6 Bcf largely represents gas used in operations. The gas purchased by the Energy Marketing segment originates
in either the Appalachian or mid-continent regions of the United States or in Canada.

Competition

Competition in the natural gas industry exists among providers of natural gas, as well as between natural
gas and other sources of energy. The natural gas industry has gone through various stages of regulation. Apart
from environmental and state utility commission regulation, the natural gas industry has experienced con-
siderable deregulation. This has enhanced the competitive position of natural gas relative to other energy
sources, such as fuel oil or electricity, since some of the historical regulatory impediments to adding customers
and responding to market forces have been removed. In addition, management believes that the environmental
advantages of natural gas have enhanced its competitive position relative to other fuels.

The electric industry has been moving toward a more competitive environment as a result of changes in
federal law in 1992 and initiatives undertaken by the FERC and various states. It remains unclear what the
impact of any further restructuring in response to legislation or other events may be.

The Company competes on the basis of price, service and reliability, product performance and other
factors. Sources and providers of energy, other than those described under this “Competition” heading, do not
compete with the Company to any significant extent.

Competition: The Utility Segment

The changes precipitated by the FERC’s restructuring of the natural gas industry in Order No. 636, which
was issued in 1992, continue to reshape the roles of the gas utility industry and the state regulatory commis-
sions. With respect to gas commodity service, in both New York and Pennsylvania, Distribution Corporation has
retained a substantial majority of small sales customers. Almost all large-volume load, however, is served by
unregulated retail marketers. In New York, approximately 20% of Distribution Corporation’s small-volume
residential and commercial customers purchase their supplies from unregulated marketers. In Pennsylvania, the
PaPUC is currently revising regulations and business practices to promote the growth of small-volume retail
competition. Retail competition for gas commodity service does not pose an acute competitive threat for
Distribution Corporation because in both jurisdictions, LDC cost of service is recovered through distribution
rates and charges, not through charges for gas commodity service. Over the longer run, however, rate design
changes resulting from further customer migration to marketer service (e.g., “unbundling”) can expose utility
companies such as Distribution Corporation to stranded costs and revenue erosion in the absence of com-
pensating rate relief.

Competition for transportation service to large-volume customers continues with local producers or
pipeline companies attempting to sell or transport gas directly to end-users located within the Utility segment’s
service territories without use of the utility’s facilities (i.e., bypass). In addition, competition continues with fuel
oil suppliers.

The Utility segment competes in its most vulnerable markets (the large commercial and industrial markets)
by offering unbundled, flexible, high quality services. The Utility segment continues to develop or promote new
sources and uses of natural gas or new services, rates and contracts.

Competition: The Pipeline and Storage Segment

Supply Corporation competes for market growth in the natural gas market with other pipeline companies
transporting gas in the northeast United States and with other companies providing gas storage services. Supply
Corporation has some unique characteristics which enhance its competitive position. Its facilities are located
adjacent to Canada and the northeastern United States and provide part of the link between gas-consuming
regions of the eastern United States and gas-producing regions of Canada and the southwestern, southern and
other continental regions of the United States. New productive areas in the Appalachian region related to the
development of the Marcellus Shale formation, in addition to the aforementioned regions, offer the opportunity
for increased transportation and storage services in the future.

Empire competes for market growth in the natural gas market with other pipeline companies transporting
gas in the northeast United States and upstate New York in particular. Empire is well situated to provide
transportation from Canadian sourced gas, and its facilities are readily expandable. These characteristics
provide Empire the opportunity to compete for an increased share of the gas transportation markets. As noted
above, Empire has constructed the Empire Connector project, which expands its natural gas pipeline and
enables Empire to serve new markets in New York and elsewhere in the Northeast. For further discussion of this
project, refer to Item 7, MD&A under the headings “Investing Cash Flow” and “Rate and Regulatory Matters.”

Competition: The Exploration and Production Segment

The Exploration and Production segment competes with other oil and natural gas producers and marketers
with respect to sales of oil and natural gas. The Exploration and Production segment also competes, by
competitive bidding and otherwise, with other oil and natural gas producers with respect to exploration and
development prospects.

To compete in this environment, Seneca originates and acts as operator on certain of its prospects, seeks to
minimize the risk of exploratory efforts through partnership-type arrangements, utilizes technology for both
exploratory studies and drilling operations, and seeks market niches based on size, operating expertise and
financial criteria.

8

Competition: The Energy Marketing Segment

The Energy Marketing segment competes with other marketers of natural gas and with other providers of
energy supply. Competition in this area is well developed with regard to price and services from local, regional
and, more recently, national marketers.

Seasonality

Variations in weather conditions can materially affect the volume of gas delivered by the Utility segment, as
virtually all of its residential and commercial customers use gas for space heating. The effect that this has on
Utility segment margins in New York is mitigated by a WNC, which covers the eight-month period from October
through May. Weather that is warmer than normal results in an upward adjustment to customers’ current bills,
while weather that is colder than normal results in a downward adjustment, so that in either case projected
operating costs calculated at normal temperatures will be recovered.

Volumes transported and stored by Supply Corporation and volumes transported by Empire may vary
materially depending on weather, without materially affecting revenues. Supply Corporation’s and Empire’s
allowed rates are based on a straight fixed-variable rate design which allows recovery of fixed costs in fixed
monthly reservation charges. Variable charges based on volumes are designed to recover only the variable costs
associated with actual transportation or storage of gas.

Variations in weather conditions materially affect the volume of gas consumed by customers of the Energy

Marketing segment. Volume variations have a corresponding impact on revenues within this segment.

Capital Expenditures

A discussion of capital expenditures by business segment is included in Item 7, MD&A under the heading

“Investing Cash Flow.”

Environmental Matters

A discussion of material environmental matters involving the Company is included in Item 7, MD&A

under the heading “Environmental Matters” and in Item 8, Note I — Commitments and Contingencies.

Miscellaneous

The Company and its wholly owned or majority-owned subsidiaries had a total of 1,949 full-time
employees at September 30, 2009. This compares to 1,943 employees in the Company’s operations at
September 30, 2008.

The Company has agreements in place with collective bargaining units in New York and Pennsylvania. The
agreements in New York are scheduled to expire in February 2013 and the agreements in Pennsylvania are
scheduled to expire in April 2014 and May 2014.

The Utility segment has numerous municipal franchises under which it uses public roads and certain other
rights-of-way and public property for the location of facilities. When necessary, the Utility segment renews such
franchises.

The Company makes its annual report on Form 10-K, quarterly reports on Form 10-Q, current reports on
Form 8-K, and any amendments to those reports, available free of charge on the Company’s internet website,

Item 1A Risk Factors

As a holding company, the Company depends on its operating subsidiaries to meet its financial
obligations.

The Company is a holding company with no significant assets other than the stock of its operating
subsidiaries. In order to meet its financial needs, the Company relies exclusively on repayments of principal and
interest on intercompany loans made by the Company to its operating subsidiaries and income from dividends
and other cash flow from the subsidiaries. Such operating subsidiaries may not generate sufficient net income to
pay upstream dividends or generate sufficient cash flow to make payments of principal or interest on such
intercompany loans.

The Company is dependent on credit markets to successfully execute its business strategies.

The Company relies upon short-term bank borrowings, commercial paper markets and longer-term capital
markets to finance capital requirements not satisfied by cash flow from operations. The Company is dependent
on these capital sources to provide capital to its subsidiaries to fund operations, acquire, maintain and develop
properties, and execute growth strategies. The availability and cost of credit sources may be cyclical and these
capital sources may not remain available to the Company. Turmoil in credit markets may make it difficult for the
Company to obtain financing on acceptable terms or at all for working capital, capital expenditures and other
investments, or to refinance maturing debt on favorable terms. These difficulties could adversely affect the
Company’s growth strategies, operations and financial performance. The Company’s ability to borrow under its
credit facilities and commercial paper agreements, and its ability to issue long-term debt under its indentures,
depend on the Company’s compliance with its obligations under the facilities, agreements and indentures. In
addition, the Company’s short-term bank loans are in the form of floating rate debt or debt that may have rates
fixed for very short periods of time, resulting in exposure to interest rate fluctuations in the absence of interest
rate hedging transactions. The cost of long-term debt, the interest rates on the Company’s short-term bank loans
and the ability of the Company to issue commercial paper are affected by its debt credit ratings published by
Standard & Poor’s Ratings Service (“S&P”), Moody’s Investors Service and Fitch Ratings Service. A downgrade
in the Company’s credit ratings could increase borrowing costs and negatively impact the availability of capital
from banks, commercial paper purchasers and other sources.

The Company may be adversely affected by economic conditions and their impact on our suppliers and
customers.

Periods of slowed economic activity generally result in decreased energy consumption, particularly by
industrial and large commercial companies. As a consequence, national or regional recessions or other
downturns in economic activity could adversely affect the Company’s revenues and cash flows or restrict its
future growth. Economic conditions in the Company’s utility service territories and energy marketing territories
also impact its collections of accounts receivable. All of the Company’s segments are exposed to risks associated
with the creditworthiness or performance of key suppliers and customers, many of which may be adversely
affected by volatile conditions in the financial markets. These conditions could result in financial instability or
other adverse effects at any of our suppliers or customers. For example, counterparties to the Company’s
commodity hedging arrangements or commodity sales contracts might not be able to perform their obligations
under these arrangements or contracts. Customers of the Company’s Utility and Energy Marketing segments
may have particular trouble paying their bills during periods of declining economic activity and high com-
modity prices, potentially resulting in increased bad debt expense and reduced earnings. Any of these events
could have a material adverse effect on the Company’s results of operations, financial condition and cash flows.

The Company’s credit ratings may not reflect all the risks of an investment in its securities.

The Company’s credit ratings are an independent assessment of its ability to pay its obligations. Conse-
quently, real or anticipated changes in the Company’s credit ratings will generally affect the market value of the
specific debt instruments that are rated, as well as the market value of the Company’s common stock. The

11

Company’s credit ratings, however, may not reflect the potential impact on the value of its common stock of
risks related to structural, market or other factors discussed in this Form 10-K.

The Company’s need to comply with comprehensive, complex, and sometimes unpredictable government
regulations may increase its costs and limit its revenue growth, which may result in reduced earnings.

While the Company generally refers to its Utility segment and its Pipeline and Storage segment as its
“regulated segments,” there are many governmental regulations that have an impact on almost every aspect of
the Company’s businesses. Existing statutes and regulations may be revised or reinterpreted and new laws and
regulations may be adopted or become applicable to the Company, which may affect its business in ways that the
Company cannot predict.

In the Company’s Utility segment, the operations of Distribution Corporation are subject to the jurisdiction
of the NYPSC, the PaPUC and, with respect to certain transactions, the FERC. The NYPSC and the PaPUC,
among other things, approve the rates that Distribution Corporation may charge to its utility customers. Those
approved rates also impact the returns that Distribution Corporation may earn on the assets that are dedicated to
those operations. If Distribution Corporation is required in a rate proceeding to reduce the rates it charges its
utility customers, or to the extent Distribution Corporation is unable to obtain approval for rate increases from
these regulators, particularly when necessary to cover increased costs (including costs that may be incurred in
connection with governmental investigations or proceedings or mandated infrastructure inspection, mainte-
nance or replacement programs), earnings may decrease.

In addition to their historical methods of utility regulation, both the PaPUC and NYPSC have sought to
establish competitive markets in which customers may purchase gas commodity from unregulated marketers, in
addition to utility companies. To date those efforts have been more successful in New York, where approx-
imately 20% of Distribution Corporation’s retail sales customers purchase gas commodity from unregulated
marketers, than in Pennsylvania, where retail competition remains a fledgling movement. The PaPUC, however,
has undertaken recent measures to enhance competition in that state. Retail competition for gas commodity
service does not pose an acute competitive threat for Distribution Corporation, because in both jurisdictions, it
recovers its cost of service through distribution rates and charges, and not through any mark-up on the gas
commodity purchased by its customers. Over the longer run, however, rate design changes resulting from
further customer migration to marketer service (“unbundling”) can expose utilities such as Distribution
Corporation to stranded costs and revenue erosion in the absence of compensating rate relief.

Both the NYPSC and the PaPUC have instituted proceedings for the purpose of promoting conservation of
energy commodities, including natural gas. In New York, Distribution Corporation implemented a Conser-
vation Incentive Program that promotes conservation and efficient use of natural gas by offering customer
rebates for high-efficiency appliances, among other things. The intent of conservation and efficiency programs is
to reduce customer usage of natural gas. Under traditional volumetric rates, reduced usage by customers results
in decreased revenues to the Utility. To prevent revenue erosion caused by conservation, the NYPSC approved a
“revenue decoupling mechanism” that renders Distribution Corporation’s New York division financially
indifferent to the effects of conservation. In Pennsylvania, although a proceeding is pending, the PaPUC
has not yet directed Distribution Corporation to implement conservation measures. If the NYPSC were to
revoke the revenue decoupling mechanism in a future proceeding or the PaPUC were to adopt a conservation
program without a revenue decoupling mechanism or other changes in rate design, reduced customer usage
could decrease revenues, forcing Distribution Corporation to file for rate relief.

In New York, aggressive generic statewide programs created under the label of efficiency or conservation
continue to generate a sizable utility funding requirement for state agencies that administer those programs.
Although utilities are authorized to recover the cost of efficiency and conservation program funding through
special rates and surcharges, the resulting upward pressure on customer rates, coupled with increased
assessments and taxes, could affect future tolerance for traditional utility rate increases, especially if gas costs
were to increase.

The Company is subject to the jurisdiction of the FERC with respect to Supply Corporation, Empire and
some transactions performed by other Company subsidiaries, including Seneca Resources, Distribution

12

Corporation and NFR. The FERC, among other things, approves the rates that Supply Corporation and Empire
may charge to their natural gas transportation and/or storage customers. Those approved rates also impact the
returns that Supply Corporation and Empire may earn on the assets that are dedicated to those operations. State
commissions can also petition the FERC to investigate whether Supply Corporation’s and Empire’s rates are still
just and reasonable, and if not, to reduce those rates prospectively. If Supply Corporation or Empire is required
in a rate proceeding to reduce the rates it charges its natural gas transportation and/or storage customers, or if
Supply Corporation or Empire is unable to obtain approval for rate increases, particularly when necessary to
cover increased costs, Supply Corporation’s or Empire’s earnings may decrease. The FERC also possesses
significant penalty authority with respect to violations of the laws and regulations it administers. Supply
Corporation, Empire and, to the extent subject to FERC jurisdiction, the Company’s other subsidiaries are
subject to the FERC’s penalty authority.

The Company’s liquidity, and in certain circumstances, its earnings, could be adversely affected by the
cost of purchasing natural gas during periods in which natural gas prices are rising significantly.

Tariff rate schedules in each of the Utility segment’s service territories contain purchased gas adjustment
clauses which permit Distribution Corporation to file with state regulators for rate adjustments to recover
increases in the cost of purchased gas. Assuming those rate adjustments are granted, increases in the cost of
purchased gas have no direct impact on profit margins. Nevertheless, increases in the cost of purchased gas affect
cash flows and can therefore impact the amount or availability of the Company’s capital resources. The
Company has issued commercial paper and used short-term borrowings in the past to temporarily finance
storage inventories and purchased gas costs, and although the Company expects to do so in the future, it may
not be able to access the markets for such borrowings at attractive interest rates or at all. Distribution
Corporation is required to file an accounting reconciliation with the regulators in each of the Utility segment’s
service territories regarding the costs of purchased gas. Due to the nature of the regulatory process, there is a risk
of a disallowance of full recovery of these costs during any period in which there has been a substantial upward
spike in these costs. Any material disallowance of purchased gas costs could have a material adverse effect on
cash flow and earnings. In addition, even when Distribution Corporation is allowed full recovery of these
purchased gas costs, during periods when natural gas prices are significantly higher than historical levels,
customers may have trouble paying the resulting higher bills, and Distribution Corporation’s bad debt expenses
may increase and ultimately reduce earnings.

Changes in interest rates may affect the Company’s ability to finance capital expenditures and to refinance
maturing debt.

The Company’s ability to finance capital expenditures and to refinance maturing debt will depend in part
upon interest rates. The direction in which interest rates may move is uncertain. Declining interest rates have
generally been believed to be favorable to utilities, while rising interest rates are generally believed to be
unfavorable, because of the levels of debt that utilities may have outstanding. In addition, the Company’s
authorized rate of return in its regulated businesses is based upon certain assumptions regarding interest rates. If
interest rates are lower than assumed rates, the Company’s authorized rate of return could be reduced. If interest
rates are higher than assumed rates, the Company’s ability to earn its authorized rate of return may be adversely
impacted.

Decreased oil and natural gas prices could adversely affect revenues, cash flows and profitability.

The Company’s exploration and production operations are materially dependent on prices received for its
oil and natural gas production. Both short-term and long-term price trends affect the economics of exploring for,
developing, producing, gathering and processing oil and natural gas. Oil and natural gas prices can be volatile
and can be affected by: weather conditions, including natural disasters; the supply and price of foreign oil and
natural gas; the level of consumer product demand; national and worldwide economic conditions, including
economic disruptions caused by terrorist activities, acts of war or major accidents; political conditions in foreign
countries; the price and availability of alternative fuels; the proximity to, and availability of capacity on
transportation facilities; regional levels of supply and demand; energy conservation measures; and government

13

regulations, such as regulation of natural gas transportation, royalties, and price controls. The Company sells
most of its oil and natural gas at current market prices rather than through fixed-price contracts, although as
discussed below, the Company frequently hedges the price of a significant portion of its future production in the
financial markets. The prices the Company receives depend upon factors beyond the Company’s control,
including the factors affecting price mentioned above. The Company believes that any prolonged reduction in
oil and natural gas prices would restrict its ability to continue the level of exploration and production activity
the Company otherwise would pursue, which could have a material adverse effect on its revenues, cash flows
and results of operations.

The Company has significant transactions involving price hedging of its oil and natural gas production
as well as its fixed price purchase and sale commitments.

In order to protect itself to some extent against unusual price volatility and to lock in fixed pricing on oil
and natural gas production for certain periods of time, the Company regularly enters into commodity price
derivatives contracts (hedging arrangements) with respect to a portion of its expected production. These
contracts may at any time cover as much as approximately 80% of the Company’s expected energy production
during the upcoming 12-month period. These contracts reduce exposure to subsequent price drops but can also
limit the Company’s ability to benefit from increases in commodity prices. In addition, the Energy Marketing
segment enters into certain hedging arrangements, primarily with respect to its fixed price purchase and sales
commitments and its gas stored underground. The Company’s Pipeline and Storage segment enters into hedging
arrangements with respect to certain sales of efficiency gas.

Under applicable accounting rules, the Company’s hedging arrangements are subject to quarterly effec-
tiveness tests. Inherent within those effectiveness tests are assumptions concerning the long-term price
differential between different types of crude oil, assumptions concerning the difference between published
natural gas price indexes established by pipelines in which hedged natural gas production is delivered and the
reference price established in the hedging arrangements, assumptions regarding the levels of production that
will be achieved and, with regard to fixed price commitments, assumptions regarding the creditworthiness of
certain customers and their forecasted consumption of natural gas. Depending on market conditions for natural
gas and crude oil and the levels of production actually achieved, it is possible that certain of those assumptions
may change in the future, and, depending on the magnitude of any such changes, it is possible that a portion of
the Company’s hedges may no longer be considered highly effective. In that case, gains or losses from the
ineffective derivative financial instruments would be marked-to-market on the income statement without
regard to an underlying physical transaction. Gains would occur to the extent that natural gas and crude oil
hedge prices exceed market prices for the Company’s natural gas and crude oil production, and losses would
occur to the extent that market prices for the Company’s natural gas and crude oil production exceed hedge
prices.

Use of energy commodity price hedges also exposes the Company to the risk of non-performance by a
contract counterparty. These parties might not be able to perform their obligations under the hedge
arrangements.

It is the Company’s policy that the use of commodity derivatives contracts comply with various restrictions
in effect in respective business segments. For example, in the Exploration and Production segment, commodity
derivatives contracts must be confined to the price hedging of existing and forecast production, and in the
Energy Marketing segment, commodity derivatives with respect to fixed price purchase and sales commitments
must be matched against commitments reasonably certain to be fulfilled. Similar restrictions apply in the
Pipeline and Storage segment. The Company maintains a system of internal controls to monitor compliance
with its policy. However, unauthorized speculative trades, if they were to occur, could expose the Company to
substantial losses to cover positions in its derivatives contracts. In addition, in the event the Company’s actual
production of oil and natural gas falls short of hedged forecast production, the Company may incur substantial
losses to cover its hedges.

14

You should not place undue reliance on reserve information because such information represents
estimates.

This Form 10-K contains estimates of the Company’s proved oil and natural gas reserves and the future net
cash flows from those reserves that were prepared by the Company’s petroleum engineers and audited by
independent petroleum engineers. Petroleum engineers consider many factors and make assumptions in
estimating oil and natural gas reserves and future net cash flows. These factors include: historical production
from the area compared with production from other producing areas; the assumed effect of governmental
regulation; and assumptions concerning oil and natural gas prices, production and development costs,
severance and excise taxes, and capital expenditures. Lower oil and natural gas prices generally cause estimates
of proved reserves to be lower. Estimates of reserves and expected future cash flows prepared by different
engineers, or by the same engineers at different times, may differ substantially. Ultimately, actual production,
revenues and expenditures relating to the Company’s reserves will vary from any estimates, and these variations
may be material. Accordingly, the accuracy of the Company’s reserve estimates is a function of the quality of
available data and of engineering and geological interpretation and judgment.

If conditions remain constant, then the Company is reasonably certain that its reserve estimates represent
economically recoverable oil and natural gas reserves and future net cash flows. If conditions change in the
future, then subsequent reserve estimates may be revised accordingly. You should not assume that the present
value of future net cash flows from the Company’s proved reserves is the current market value of the Company’s
estimated oil and natural gas reserves. In accordance with SEC requirements, the Company bases the estimated
discounted future net cash flows from its proved reserves on prices and costs as of the date of the estimate.
Actual future prices and costs may differ materially from those used in the net present value estimate. Any
significant price changes will have a material effect on the present value of the Company’s reserves.

Petroleum engineering is a subjective process of estimating underground accumulations of natural gas and
other hydrocarbons that cannot be measured in an exact manner. The process of estimating oil and natural gas
reserves is complex. The process involves significant decisions and assumptions in the evaluation of available
geological, geophysical, engineering and economic data for each reservoir. Future economic and operating
conditions are uncertain, and changes in those conditions could cause a revision to the Company’s reserve
estimates in the future. Estimates of economically recoverable oil and natural gas reserves and of future net cash
flows depend upon a number of variable factors and assumptions, including historical production from the area
compared with production from other comparable producing areas, and the assumed effects of regulations by
governmental agencies. Because all reserve estimates are to some degree subjective, each of the following items
may differ materially from those assumed in estimating reserves: the quantities of oil and natural gas that are
ultimately recovered, the timing of the recovery of oil and natural gas reserves, the production and operating
costs incurred, the amount and timing of future development and abandonment expenditures, and the price
received for the production.

The amount and timing of actual future oil and natural gas production and the cost of drilling are
difficult to predict and may vary significantly from reserves and production estimates, which may reduce
the Company’s earnings.

There are many risks in developing oil and natural gas, including numerous uncertainties inherent in
estimating quantities of proved oil and natural gas reserves and in projecting future rates of production and
timing of development expenditures. The future success of the Company’s Exploration and Production segment
depends on its ability to develop additional oil and natural gas reserves that are economically recoverable, and
its failure to do so may reduce the Company’s earnings. The total and timing of actual future production may
vary significantly from reserves and production estimates. The Company’s drilling of development wells can
involve significant risks, including those related to timing, success rates, and cost overruns, and these risks can
be affected by lease and rig availability, geology, and other factors. Drilling for oil and natural gas can be
unprofitable, not only from non-productive wells, but from productive wells that do not produce sufficient
revenues to return a profit. Also, title problems, weather conditions, governmental requirements, including
completion of environmental impact analyses and compliance with other environmental laws and regulations,
and shortages or delays in the delivery of equipment and services can delay drilling operations or result in their

15

cancellation. The cost of drilling, completing, and operating wells is often uncertain, and new wells may not be
productive or the Company may not recover all or any portion of its investment. Without continued successful
exploitation or acquisition activities, the Company’s reserves and revenues will decline as a result of its current
reserves being depleted by production. The Company cannot assure you that it will be able to find or acquire
additional reserves at acceptable costs.

Financial accounting requirements regarding exploration and production activities may affect the
Company’s profitability.

The Company accounts for its exploration and production activities under the full cost method of
accounting. Each quarter, the Company must compare the level of its unamortized investment in oil and
natural gas properties to the present value of the future net revenue projected to be recovered from those
properties according to methods prescribed by the SEC. In determining present value, the Company uses
quarter-end spot prices for oil and natural gas (as adjusted for hedging). If, at the end of any quarter, the amount
of the unamortized investment exceeds the net present value of the projected future cash flows, such investment
may be considered to be “impaired,” and the full cost accounting rules require that the investment must be
written down to the calculated net present value. Such an instance would require the Company to recognize an
immediate expense in that quarter, and its earnings would be reduced. The Company’s Exploration and
Production segment recorded an impairment charge under the full cost method of accounting in the quarter
ended December 31, 2008. If spot market prices at a subsequent quarter end are lower than prices at
December 31, 2008, absent any changes in other factors affecting the present value of the future net revenue
projected to be recovered from the Company’s oil and natural gas properties, the Company would be required to
record an additional impairment charge. Depending on the magnitude of the decrease in prices, that charge
could be material.

Environmental regulation significantly affects the Company’s business.

The Company’s business operations are subject to federal, state, and local laws and regulations relating to
environmental protection. These laws and regulations concern the generation, storage, transportation, disposal
or discharge of contaminants and greenhouse gases into the environment, the reporting of such matters, and the
general protection of public health, natural resources, wildlife and the environment. Costs of compliance and
liabilities could negatively affect the Company’s results of operations, financial condition and cash flows. In
addition, compliance with environmental laws and regulations could require unexpected capital expenditures
at the Company’s facilities or delay or cause the cancellation of expansion projects or oil and natural gas drilling
activities. Because the costs of complying with environmental regulations are significant, additional regulation
could negatively affect the Company’s business. Although the Company cannot predict the impact of the
interpretation or enforcement of EPA standards or other federal, state and local regulations, the Company’s costs
could increase if environmental laws and regulations become more strict.

The nature of the Company’s operations presents inherent risks of loss that could adversely affect its
results of operations, financial condition and cash flows.

The Company’s operations in its various segments are subject to inherent hazards and risks such as: fires;
natural disasters; explosions; geological formations with abnormal pressures; blowouts during well drilling;
collapses of wellbore casing or other tubulars; pipeline ruptures; spills; and other hazards and risks that may
cause personal injury, death, property damage, environmental damage or business interruption losses. Addi-
tionally, the Company’s facilities, machinery, and equipment may be subject to sabotage. Any of these events
could cause a loss of hydrocarbons, environmental pollution, claims for personal injury, death, property damage
or business interruption, or governmental investigations, recommendations, claims, fines or penalties. As
protection against operational hazards, the Company maintains insurance coverage against some, but not all,
potential losses. In addition, many of the agreements that the Company executes with contractors provide for
the division of responsibilities between the contractor and the Company, and the Company seeks to obtain an
indemnification from the contractor for certain of these risks. The Company is not always able, however, to

16

secure written agreements with its contractors that contain indemnification, and sometimes the Company is
required to indemnify others.

Insurance or indemnification agreements when obtained may not adequately protect the Company against
liability from all of the consequences of the hazards described above. The occurrence of an event not fully
insured or indemnified against, the imposition of fines, penalties or mandated programs by governmental
authorities, the failure of a contractor to meet its indemnification obligations, or the failure of an insurance
company to pay valid claims could result in substantial losses to the Company . In addition, insurance may not
be available, or if available may not be adequate, to cover any or all of these risks. It is also possible that
insurance premiums or other costs may rise significantly in the future, so as to make such insurance
prohibitively expensive.

Due to the significant cost of insurance coverage for named windstorms in the Gulf of Mexico, the
Company determined that it was not economical to purchase insurance to fully cover its exposures related to
such storms. It is possible that named windstorms in the Gulf of Mexico could have a material adverse effect on
the Company’s results of operations, financial condition and cash flows.

Hazards and risks faced by the Company, and insurance and indemnification obtained or provided by the
Company, may subject the Company to litigation or administrative proceedings from time to time. Such
litigation or proceedings could result in substantial monetary judgments, fines or penalties against the Company
or be resolved on unfavorable terms, the result of which could have a material adverse effect on the Company’s
results of operations, financial condition and cash flows.

The increasing costs of certain employee and retiree benefits could adversely affect the Company’s
results.

The Company’s earnings and cash flow may be impacted by the amount of income or expense it expends or
records for employee benefit plans. This is particularly true for pension plans, which are dependent on actual
plan asset returns and factors used to determine the value and current costs of plan benefit obligations. In
addition, if medical costs rise at a rate faster than the general inflation rate, the Company might not be able to
mitigate the rising costs of medical benefits. Increases to the costs of pension and medical benefits could have an
adverse effect on the Company’s financial results.

Significant shareholders or potential shareholders may attempt to effect changes at the Company or
acquire control over the Company, which could adversely affect the Company’s results of operations and
financial condition.

In January 2008, the Company entered into an agreement with New Mountain Vantage GP, L.L.C. (“New
Mountain”) and certain parties related to New Mountain, including the California Public Employees’ Retire-
ment System (collectively, “Vantage”), to settle a proxy contest pertaining to the election of directors to the
Company’s Board of Directors at the Company’s 2008 Annual Meeting of Stockholders. That settlement
agreement expired on September 15, 2009. Vantage or other existing or potential shareholders may engage
in proxy solicitations or advance shareholder proposals after the Company’s 2010 Annual Meeting of Stock-
holders, or otherwise attempt to effect changes or acquire control over the Company.

Campaigns by shareholders to effect changes at publicly traded companies are sometimes led by investors
seeking to increase short-term shareholder value through actions such as financial restructuring, increased debt,
special dividends, stock repurchases or sales of assets or the entire company. Responding to proxy contests and
other actions by activist shareholders can be costly and time-consuming, disrupting the Company’s operations
and diverting the attention of the Company’s Board of Directors and senior management from the pursuit of
business strategies. As a result, shareholder campaigns could adversely affect the Company’s results of
operations and financial condition.

Item 2 Properties

General Information on Facilities

The net investment of the Company in property, plant and equipment was $3.1 billion at September 30,
2009. Approximately 63% of this investment was in the Utility and Pipeline and Storage segments, which are
primarily located in western and central New York and northwestern Pennsylvania. The Exploration and
Production segment, which has the next largest investment in net property, plant and equipment (33%), is
primarily located in California, in the Appalachian region of the United States, and in the Gulf Coast region of
Texas and Louisiana. The remaining net investment in property, plant and equipment consisted of the All Other
and Corporate operations (4%). During the past five years, the Company has made additions to property, plant
and equipment in order to expand and improve transmission and distribution facilities for both retail and
transportation customers. Net property, plant and equipment has increased $125.3 million, or 4.2%, since 2004.
During 2007, the Company sold SECI, Seneca’s wholly owned subsidiary that operated in Canada. The net
property, plant and equipment of SECI at the date of sale was $107.7 million. In addition, during 2005, the
Company sold its majority interest in U.E., a district heating and electric generation business in the Czech
Republic. The net property, plant and equipment of U.E. at the date of sale was $223.9 million.

The Utility segment had a net investment in property, plant and equipment of $1.1 billion at September 30,
2009. The net investment in its gas distribution network (including 14,837 miles of distribution pipeline) and
its service connections to customers represent approximately 52% and 34%, respectively, of the Utility segment’s
net investment in property, plant and equipment at September 30, 2009.

The Pipeline and Storage segment had a net investment of $839.4 million in property, plant and equipment
at September 30, 2009. Transmission pipeline represents 43% of this segment’s total net investment and includes
2,364 miles of pipeline utilized to move large volumes of gas throughout its service area. Storage facilities
represent 20% of this segment’s total net investment and consist of 31 storage fields, four of which are jointly
owned and operated with certain pipeline suppliers, and 428 miles of pipeline. Net investment in storage
facilities includes $89.7 million of gas stored underground-noncurrent, representing the cost of the gas utilized
to maintain pressure levels for normal operating purposes as well as gas maintained for system balancing and
other purposes, including that needed for no-notice transportation service. The Pipeline and Storage segment
has 28 compressor stations with 95,949 installed compressor horsepower that represent 10% of this segment’s
total net investment in property, plant and equipment.

The Exploration and Production segment had a net investment in property, plant and equipment of

$1.0 billion at September 30, 2009.

The Utility and Pipeline and Storage segments’ facilities provided the capacity to meet the Company’s 2009
peak day sendout, including transportation service, of 1,733 MMcf, which occurred on January 15, 2009.
Withdrawals from storage of 694.1 MMcf provided approximately 40.1% of the requirements on that day.

Exploration and Production Activities

The Company is engaged in the exploration for, and the development and purchase of, natural gas and oil
reserves in California, in the Appalachian region of the United States, and in the Gulf Coast region of Texas and
Louisiana. Also, Exploration and Production operations were conducted in the provinces of Alberta,
Saskatchewan and British Columbia in Canada, until the sale of these properties on August 31, 2007. Further
discussion of the sale of the Canadian oil and gas properties is included in Item 8, Note J — Discontinued
Operations. Further discussion of oil and gas producing activities is included in Item 8, Note Q — Supple-
mentary Information for Oil and Gas Producing Activities. Note Q sets forth proved developed and undeveloped
reserve information for Seneca.

Seneca’s proved developed and undeveloped natural gas reserves increased from 226 Bcf at September 30,
2008 to 249 Bcf at September 30, 2009. This increase is attributed primarily to extensions and discoveries
(59.2 Bcf), primarily in the Appalachian region (49.2 Bcf). This increase was partially offset by production of

18

22.3 Bcf, negative revisions of previous estimates (9.6 Bcf) and sales of minerals in place (4.7 Bcf) in the Gulf
Coast region. Seneca’s proved developed and undeveloped oil reserves increased from 46,198 Mbbl at
September 30, 2008 to 46,587 Mbbl at September 30, 2009. This increase is attributed to purchases of minerals
in place (2,115 Mbbl) in the West Coast region, extensions and discoveries (1,213 Mbbl), and revisions of
previous estimates (449 Mbbl). These increases were largely offset by production (3,373 Mbbl), primarily
occurring in the West Coast region (2,674 Mbbl). On a Bcfe basis, Seneca’s proved developed and undeveloped
reserves increased from 503 Bcfe at September 30, 2008 to 528 Bcfe at September 30, 2009.

Seneca’s proved developed and undeveloped natural gas reserves increased from 205 Bcf at September 30,
2007 to 226 Bcf at September 30, 2008. This increase is attributed primarily to extensions and discoveries
(40.1 Bcf), primarily in the Appalachian region (31.3 Bcf). This increase was partially offset by production of
22.3 Bcf. Seneca’s proved developed and undeveloped oil reserves decreased from 47,586 Mbbl at September 30,
2007 to 46,198 Mbbl at September 30, 2008. This decrease is attributed to production (3,070 Mbbl), primarily
occurring in the West Coast region (2,460 Mbbl) and sales of minerals in place (1,334 Mbbl). These decreases
were partially offset by purchases of minerals in place (2,084 Mbbl) and extensions and discoveries (827 Mbbl).
On a Bcfe basis, Seneca’s proved developed and undeveloped reserves increased from 491 Bcfe at September 30,
2007 to 503 Bcfe at September 30, 2008.

Seneca’s oil and gas reserves reported in Item 8 at Note Q as of September 30, 2009 were estimated by
Seneca’s geologists and engineers and were audited by independent petroleum engineers from Netherland,
Sewell & Associates, Inc. Seneca reports its oil and gas reserve information on an annual basis to the Energy
Information Administration (EIA), a statistical agency of the U.S. Department of Energy. The oil and gas reserve
information reported to the EIA showed 227 Bcf and 47,630 Mbbl of gas and oil reserves, respectively, which
differs from the reserve information summarized in Item 8 at Note Q. The reasons for this difference are as
follows: (a) reserves are reported to the EIA on a calendar year basis, while reserves disclosed in Item 8 at Note Q
are shown on a fiscal year basis; (b) reserves reported to the EIA include only properties operated by Seneca,
while reserves disclosed in Item 8 at Note Q included both Seneca operated properties and non-operated
properties in which Seneca has an interest; and (c) reserves are reported to the EIA on a gross basis versus the
reserves disclosed in Item 8 at Note Q, which are reported on a net revenue interest basis.

The following is a summary of certain oil and gas information taken from Seneca’s records. All monetary

amounts are expressed in U.S. dollars.

Item 3 Legal Proceedings

For a discussion of various environmental and other matters, refer to Part II, Item 7, MD&A and Item 8 at
Note I — Commitments and Contingencies. In addition to these matters, the Company is involved in other
litigation and regulatory matters arising in the normal course of business. These other matters may include, for
example, negligence claims and tax, regulatory or other governmental audits, inspections, investigations or
other proceedings. These matters may involve state and federal taxes, safety, compliance with regulations, rate
base, cost of service, and purchased gas cost issues, among other things. While these normal-course matters
could have a material effect on earnings and cash flows in the quarterly and annual period in which they are
resolved, they are not expected to change materially the Company’s present liquidity position, nor are they
expected to have a material adverse effect on the financial condition of the Company.

Item 4 Submission of Matters to a Vote of Security Holders

No matter was submitted to a vote of security holders during the quarter ended September 30, 2009.

seven non-employee directors of the Company then serving on the Board of Directors of the Company and
receiving compensation under the Company’s Retainer Policy for Non-Employee Directors, 400 shares to each
such director. On September 30, 2009, the Company issued 65 unregistered shares of Company common stock
to Frederic V. Salerno, a non-employee director of the Company, under the Company’s Retainer Policy for Non-
Employee Directors. All of these unregistered shares were issued as partial consideration for such directors’
services during the quarter ended September 30, 2009. These transactions were exempt from registration under
Section 4(2) of the Securities Act of 1933, as transactions not involving a public offering.

Item 7 Management’s Discussion and Analysis of Financial Condition and Results of Operations

OVERVIEW

The Company is a diversified energy company and reports financial results for four business segments.
Refer to Item 1, Business, for a more detailed description of each of the segments. This Item 7, MD&A, provides
information concerning:

1. The critical accounting estimates of the Company;

2. Changes in revenues and earnings of the Company under the heading, “Results of Operations;”

3. Operating, investing and financing cash flows under the heading “Capital Resources and Liquidity;”

4. Off-Balance Sheet Arrangements;

25

5. Contractual Obligations; and

6. Other Matters, including: (a) 2009 and projected 2010 funding for the Company’s pension and other
post-retirement benefits, (b) realizability of deferred tax assets (c) disclosures and tables concerning
market risk sensitive instruments, (d) rate and regulatory matters in the Company’s New York,
Pennsylvania and FERC regulated jurisdictions, (e) environmental matters, and (f) new authoritative
accounting and financial reporting guidance.

The information in MD&A should be read in conjunction with the Company’s financial statements in

Item 8 of this report.

For the year ended September 30, 2009 compared to the year ended September 30, 2008, the Company
experienced a decrease in earnings of $168.0 million, primarily due to lower earnings in the Exploration and
Production segment. The earnings decrease was driven largely by an impairment charge of $182.8 million
($108.2 million after tax) recorded in the Exploration and Production segment, along with reduced crude oil
and natural gas prices. In the Company’s Exploration and Production segment, oil and gas property acquisition,
exploration and development costs are capitalized under the full cost method of accounting. Such costs are
subject to a quarterly ceiling test prescribed by SEC Regulation S-X Rule 4-10 that determines a limit, or ceiling,
on the amount of property acquisition, exploration and development costs that can be capitalized. At
December 31, 2008, due to significant declines in crude oil and natural gas commodity prices (Cushing,
Oklahoma West Texas Intermediate oil reported spot price of $44.60 per Bbl at December 31, 2008 versus a
reported price of $100.70 per Bbl at September 30, 2008; Henry Hub natural gas reported spot price of $5.63 per
MMBtu at December 31, 2008 versus a reported price of $7.12 per MMBtu at September 30, 2008), the book
value of the Company’s oil and gas properties exceeded the ceiling, resulting in the impairment charge
mentioned above. (Note — Because actual pricing of the Company’s various producing properties varies
depending on their location, the actual various prices received for such production is utilized to calculate
the ceiling, rather than the Cushing oil and Henry Hub prices, which are only indicative of current prices.) At
September 30, 2009, the quoted Cushing, Oklahoma spot price for West Texas Intermediate oil was $70.46 per
Bbl ($69.82 per Bbl at June 30, 2009 and $49.64 per Bbl at March 31, 2009) and the quoted spot price for natural
gas was $3.30 per MMBtu ($3.88 per MMBtu at June 30, 2009 and $3.63 per MMBtu at March 31, 2009). At
September 30, 2009, the ceiling exceeded the book value of the Company’s oil and gas properties by
approximately $212 million (and approximately $247 million and $37 million at June 30, 2009 and March 31,
2009, respectively). If natural gas prices used in the ceiling test calculation at September 30, 2009 had been $1
per MMBtu lower, the ceiling would have exceeded the book value of the Company’s oil and gas properties by
approximately $165 million. If crude oil prices used in the ceiling test calculation at September 30, 2009 had
been $5 per Bbl lower, the ceiling would have exceeded the book value of the Company’s oil and gas properties
by approximately $160 million. If both natural gas and crude oil prices used in the ceiling test calculation at
September 30, 2009 were lower by $1 per MMBtu and $5 per Bbl, respectively, the ceiling would have exceeded
the book value of the Company’s oil and gas properties by approximately $113 million. These calculated
amounts are based solely on price changes and do not take into account any other changes to the ceiling test
calculation.

Despite the decrease in earnings discussed above, the Company’s balance sheet consisted of a capitalization
structure of 56% equity and 44% debt at September 30, 2009. With its April 2009 issuance of $250.0 million of
8.75% notes due in May 2019, management believes that it has enhanced its liquidity position at a time when
there is still uncertainty in the credit markets. At September 30, 2009, the Company did not have any short-term
borrowings outstanding. However, the Company continues to maintain a number of individual uncommitted or
discretionary lines of credit with financial institutions for general corporate purposes. These credit lines, which
aggregate to $420.0 million, are revocable at the option of the financial institutions and are reviewed on an
annual basis. The Company anticipates that these lines of credit will continue to be renewed, or replaced by
similar lines. The total amount available to be issued under the Company’s commercial paper program is
$300.0 million. The commercial paper program is backed by a syndicated committed credit facility totaling
$300.0 million, which commitment extends through September 30, 2010.

26

The Company’s liquidity position will become increasingly important over the next three years. The
Company anticipates spending $413 million for capital expenditures in 2010. In addition, the Company has
identified possible additional projects where capital expenditures could amount to $723 million in 2011 and
$816 million in 2012. The majority of these expenditures have been targeted for the Exploration and Production
segment, where the Company anticipates spending $255 million in 2010 ($224 million in Appalachia).
Depending on drilling success in 2010, commodity pricing, and, subject to approval of the Company’s Board
of Directors, spending could reach $417 million in 2011 ($385 million in Appalachia), and $497 million in 2012
($444 million in Appalachia). The significant rise in estimated capital expenditures in the Exploration and
Production segment, specifically in the Appalachian region, can be attributed to a strong emphasis on
developing natural gas properties in the Marcellus Shale. The emphasis on Marcellus Shale development will
carry over into the Pipeline and Storage segment, which is anticipating the need for additional pipeline and
storage capacity as Marcellus Shale production comes on line. Pipeline and Storage segment capital expen-
ditures are anticipated to be $51 million in 2010, with opportunities to spend up to $227 million in 2011 and
$240 million in 2012, depending on market acceptance of the proposed projects, contractual commitments
from shippers, and approval from the Company’s Board of Directors. The projects being considered in the
Pipeline and Storage segment are discussed in detail in the Investing Cash Flow section of the Capital Resources
and Liquidity section that follows. The Company anticipates financing these capital expenditures with cash
from operations, short-term borrowings and long-term debt.

CRITICAL ACCOUNTING ESTIMATES

The Company has prepared its consolidated financial statements in conformity with GAAP. The prepa-
ration of these financial statements requires management to make estimates and assumptions that affect the
reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the
financial statements and the reported amounts of revenues and expenses during the reporting period. Actual
results could differ from those estimates. In the event estimates or assumptions prove to be different from actual
results, adjustments are made in subsequent periods to reflect more current information. The following is a
summary of the Company’s most critical accounting estimates, which are defined as those estimates whereby
judgments or uncertainties could affect the application of accounting policies and materially different amounts
could be reported under different conditions or using different assumptions. For a complete discussion of the
Company’s significant accounting policies, refer to Item 8 at Note A — Summary of Significant Accounting
Policies.

Oil and Gas Exploration and Development Costs.

In the Company’s Exploration and Production segment,
oil and gas property acquisition, exploration and development costs are capitalized under the full cost method
of accounting. Under this accounting methodology, all costs associated with property acquisition, exploration
and development activities are capitalized,
including internal costs directly identified with acquisition,
exploration and development activities. The internal costs that are capitalized do not include any costs related
to production, general corporate overhead, or similar activities. The Company does not recognize any gain or
loss on the sale or other disposition of oil and gas properties unless the gain or loss would significantly alter the
relationship between capitalized costs and proved reserves of oil and gas attributable to a cost center.

The Company believes that determining the amount of the Company’s proved reserves is a critical
accounting estimate. Proved reserves are estimated quantities of reserves that, based on geologic and engi-
neering data, appear with reasonable certainty to be producible under existing economic and operating
conditions. Such estimates of proved reserves are inherently imprecise and may be subject to substantial
revisions as a result of numerous factors including, but not limited to, additional development activity, evolving
production history and continual reassessment of the viability of production under varying economic condi-
tions. The estimates involved in determining proved reserves are critical accounting estimates because they
serve as the basis over which capitalized costs are depleted under the full cost method of accounting (on a
units-of-production basis). Unproved properties are excluded from the depletion calculation until proved
reserves are found or it is determined that the unproved properties are impaired. All costs related to unproved
properties are reviewed quarterly to determine if impairment has occurred. The amount of any impairment is
transferred to the pool of capitalized costs being amortized.

27

In addition to depletion under the units-of-production method, proved reserves are a major component in
the SEC full cost ceiling test. The full cost ceiling test is an impairment test prescribed by SEC Regulation S-X
Rule 4-10. The ceiling test , which is performed each quarter, determines a limit, or ceiling, on the amount of
property acquisition, exploration and development costs that can be capitalized. The ceiling under this test
represents (a) the present value of estimated future net cash flows, excluding future cash outflows associated
with settling asset retirement obligations that have been accrued on the balance sheet, using a discount factor of
10%, which is computed by applying current market prices of oil and gas (as adjusted for hedging) to estimated
future production of proved oil and gas reserves as of the date of the latest balance sheet, less estimated future
expenditures, plus (b) the cost of unevaluated properties not being depleted, less (c) income tax effects related
to the differences between the book and tax basis of the properties. The estimates of future production and
future expenditures are based on internal budgets that reflect planned production from current wells and
expenditures necessary to sustain such future production. The amount of the ceiling can fluctuate significantly
from period to period because of additions to or subtractions from proved reserves and significant fluctuations
in oil and gas prices. The ceiling is then compared to the capitalized cost of oil and gas properties less
accumulated depletion and related deferred income taxes. If the capitalized costs of oil and gas properties less
accumulated depletion and related deferred taxes exceeds the ceiling at the end of any fiscal quarter, a non-cash
impairment must be recorded to write down the book value of the reserves to their present value. This non-cash
impairment cannot be reversed at a later date if the ceiling increases. It should also be noted that a non-cash
impairment to write down the book value of the reserves to their present value in any given period causes a
reduction in future depletion expense. At September 30, 2008, the ceiling exceeded the book value of the
Company’s oil and gas properties by approximately $500 million. Because of declines in commodity prices
subsequent to September 30, 2008, the book value of the Company’s oil and gas properties exceeded the ceiling
at December 31, 2008. The quoted Cushing, Oklahoma spot price for West Texas Intermediate oil had declined
from a reported price of $100.70 per Bbl at September 30, 2008 to a reported price of $44.60 per Bbl at
December 31, 2008. The quoted Henry Hub spot price for natural gas had declined from a reported price of
$7.12 per MMBtu at September 30, 2008 to a reported price of $5.63 per MMBtu at December 31, 2008.
Consequently, the Company recorded an impairment charge of $182.8 million ($108.2 million after-tax) during
the quarter ended December 31, 2008. (Note — Because actual pricing of the Company’s various producing
properties varies depending on their location, the actual various prices received for such production is utilized
to calculate the ceiling, rather than the Cushing oil and Henry Hub prices, which are only indicative of current
prices.) At September 30, 2009, the quoted Cushing, Oklahoma spot price for West Texas Intermediate oil was
$70.46 per Bbl ($69.82 per Bbl at June 30, 2009 and $49.64 per Bbl at March 31, 2009) and the quoted spot price
for natural gas was $3.30 per MMBtu ($3.88 per MMBtu at June 30, 2009 and $3.63 per MMBtu at March 31,
2009). At September 30, 2009, the ceiling exceeded the book value of the Company’s oil and gas properties by
approximately $212 million (and approximately $247 million and $37 million at June 30, 2009 and March 31,
2009, respectively). If natural gas prices used in the ceiling test calculation at September 30, 2009 had been $1
per MMBtu lower, the ceiling would have exceeded the book value of the Company’s oil and gas properties by
approximately $165 million. If crude oil prices used in the ceiling test calculation at September 30, 2009 had
been $5 per Bbl lower, the ceiling would have exceeded the book value of the Company’s oil and gas properties
by approximately $160 million. If both natural gas and crude oil prices used in the ceiling test calculation at
September 30, 2009 were lower by $1 per MMBtu and $5 per Bbl, respectively, the ceiling would have exceeded
the book value of the Company’s oil and gas properties by approximately $113 million. These calculated
amounts are based solely on price changes and do not take into account any other changes to the ceiling test
calculation.

It is difficult to predict what factors could lead to future impairments under the SEC’s full cost ceiling test.
As discussed above, fluctuations in or subtractions from proved reserves and significant fluctuations in oil and
gas prices have an impact on the amount of the ceiling at any point in time.

In accordance with the current authoritative guidance for asset retirement obligations, the Company
records an asset retirement obligation for plugging and abandonment costs associated with the Exploration and
Production segment’s crude oil and natural gas wells and capitalizes such costs in property, plant and equipment
(i.e. the full cost pool). Under the current authoritative guidance for asset retirement obligations, since plugging
and abandonment costs are already included in the full cost pool, the units-of-production depletion calculation

28

excludes from the depletion base any estimate of future plugging and abandonment costs that are already
recorded in the full cost pool.

As discussed above, the full cost method of accounting provides a ceiling to the amount of costs that can be
capitalized in the full cost pool. In accordance with current authoritative guidance, since the full cost pool
includes an amount associated with plugging and abandoning the wells, as discussed in the preceding
paragraph, the calculation of the full cost ceiling no longer reduces the future net cash flows from proved
oil and gas reserves by an estimate of plugging and abandonment costs.

Regulation. The Company is subject to regulation by certain state and federal authorities. The Company,
in its Utility and Pipeline and Storage segments, has accounting policies which conform to the FASB author-
itative guidance regarding accounting for certain types of regulations, and which are in accordance with the
accounting requirements and ratemaking practices of the regulatory authorities. The application of these
accounting policies allows the Company to defer expenses and income on the balance sheet as regulatory assets
and liabilities when it is probable that those expenses and income will be allowed in the ratesetting process in a
period different from the period in which they would have been reflected in the income statement by an
unregulated company. These deferred regulatory assets and liabilities are then flowed through the income
statement in the period in which the same amounts are reflected in rates. Management’s assessment of the
probability of recovery or pass through of regulatory assets and liabilities requires judgment and interpretation
of laws and regulatory commission orders. If, for any reason, the Company ceases to meet the criteria for
application of regulatory accounting treatment for all or part of its operations, the regulatory assets and
liabilities related to those portions ceasing to meet such criteria would be eliminated from the balance sheet and
included in the income statement for the period in which the discontinuance of regulatory accounting treatment
occurs. Such amounts would be classified as an extraordinary item. For further discussion of the Company’s
regulatory assets and liabilities, refer to Item 8 at Note C — Regulatory Matters.

Accounting for Derivative Financial Instruments. The Company, in its Exploration and Production seg-
ment, Energy Marketing segment, and Pipeline and Storage segment, uses a variety of derivative financial
instruments to manage a portion of the market risk associated with fluctuations in the price of natural gas and
crude oil. These instruments are categorized as price swap agreements and futures contracts. The Company, in
its Pipeline and Storage segment, previously used an interest rate collar to limit interest rate fluctuations on
certain variable rate debt. In accordance with the authoritative guidance for derivative instruments and hedging
activities, the Company accounted for these instruments as effective cash flow hedges or fair value hedges. In
2007, the Company discontinued hedge accounting for the interest rate collar, which resulted in a gain being
recognized. Gains or losses associated with the derivative financial instruments are matched with gains or losses
resulting from the underlying physical transaction that is being hedged. To the extent that the derivative
financial instruments would ever be deemed to be ineffective based on the effectiveness testing, mark-to-market
gains or losses from the derivative financial instruments would be recognized in the income statement without
regard to an underlying physical transaction.

The Company uses both exchange-traded and non exchange-traded derivative financial instruments. The
Company adopted the authoritative guidance for fair value measurements during the quarter ended Decem-
ber 31, 2008. As such, the fair value of such derivative financial instruments is determined under the provisions
of this guidance. The fair value of exchange traded derivative financial instruments is determined from Level 1
inputs, which are quoted prices in active markets. The Company determines the fair value of non exchange-
traded derivative financial instruments based on an internal model, which uses both observable and unob-
servable inputs other than quoted prices. These inputs are considered Level 2 or Level 3 inputs. All derivative
financial instrument assets and liabilities are evaluated for the probability of default by either the counterparty
or the Company. Credit reserves are applied against the fair values of such assets or liabilities. Refer to the
“Market Risk Sensitive Instruments” section below for further discussion of the Company’s derivative financial
instruments.

Pension and Other Post-Retirement Benefits. The amounts reported in the Company’s financial statements
related to its pension and other post-retirement benefits are determined on an actuarial basis, which uses many
assumptions in the calculation of such amounts. These assumptions include the discount rate, the expected

29

return on plan assets, the rate of compensation increase and, for other post-retirement benefits, the expected
annual rate of increase in per capita cost of covered medical and prescription benefits. The Company utilizes a
yield curve model to determine the discount rate. The yield curve is a spot rate yield curve that provides a zero-
coupon interest rate for each year into the future. Each year’s anticipated benefit payments are discounted at the
associated spot interest rate back to the measurement date. The discount rate is then determined based on the
spot interest rate that results in the same present value when applied to the same anticipated benefit payments.
The expected return on plan assets assumption used by the Company reflects the anticipated long-term rate of
return on the plan’s current and future assets. The Company utilizes historical investment data, projected capital
market conditions, and the plan’s target asset class and investment manager allocations to set the assumption
regarding the expected return on plan assets. Changes in actuarial assumptions and actuarial experience,
including deviations between actual versus expected return on plan assets, could have a material impact on the
amount of pension and post-retirement benefit costs and funding requirements experienced by the Company.
However, the Company expects to recover substantially all of its net periodic pension and other post-retirement
benefit costs attributable to employees in its Utility and Pipeline and Storage segments in accordance with the
applicable regulatory commission authorization. For financial reporting purposes, the difference between the
amounts of pension cost and post-retirement benefit cost recoverable in rates and the amounts of such costs as
determined under applicable accounting principles is recorded as either a regulatory asset or liability, as
appropriate, as discussed above under “Regulation.” Pension and post-retirement benefit costs for the Utility
and Pipeline and Storage segments, as determined under the authoritative guidance for pensions and postre-
tirement benefits, represented 90% of the Company’s total pension and post-retirement benefit costs for the
years ended September 30, 2009 and 2008.

Changes in actuarial assumptions and actuarial experience could also have an impact on the benefit
obligation and the funded status related to the Company’s pension and other post-retirement benefits and could
impact the Company’s equity. For example, the discount rate was changed from 6.75% in 2008 to 5.50% in 2009.
The change in the discount rate from 2008 to 2009 increased the Retirement Plan projected benefit obligation by
$102.6 million and the accumulated post-retirement benefit obligation by $60.9 million. Other examples
include actual versus expected return on plan assets, which has an impact on the funded status of the plans, and
actual versus expected benefit payments, which has an impact on the pension plan projected benefit obligation
and the accumulated post-retirement benefit obligation. For 2009, actual versus expected return on plan assets
resulted in a decrease to the funded status of the Retirement Plan ($157.5 million) and the VEBA trusts and
401(h) accounts ($94.0 million). The actual versus expected benefit payments for 2009 caused a decrease of
$2.2 million to the accumulated post-retirement benefit obligation. In calculating the projected benefit
obligation for the Retirement Plan and the accumulated post-retirement obligation, the actuary takes into
account the average remaining service life of active participants. The average remaining service life of active
participants is 9 years for the Retirement Plan and 8 years for those eligible for other post-retirement benefits.
For further discussion of the Company’s pension and other post-retirement benefits, refer to Other Matters in
this Item 7, which includes a discussion of funding for the current year and the adoption of FASB revised
accounting guidance for defined benefit pensions and other postretirement plans, and to Item 8 at Note H —
Retirement Plan and Other Post Retirement Benefits.

RESULTS OF OPERATIONS

EARNINGS

2009 Compared with 2008

The Company’s earnings were $100.7 million in 2009 compared with earnings of $268.7 million in 2008.
The decrease in earnings of $168.0 million is primarily the result of lower earnings in the Exploration and
Production, Pipeline and Storage and Utility segments and the All Other category, slightly offset by a lower loss
in the Corporate category and higher earnings in the Energy Marketing segment, as shown in the table below. In
the discussion that follows, note that all amounts used in the earnings discussions are after-tax amounts, unless
otherwise noted. Earnings were impacted by several events in 2009 and 2008, including:

2009 Events

(cid:129) A non-cash $182.8 million impairment charge ($108.2 million after tax) recorded during the quarter
ended December 31, 2008 for the Exploration and Production segment’s oil and gas producing
properties;

(cid:129) A $2.8 million impairment in the value of certain landfill gas assets in the All Other category;

(cid:129) A $1.1 million impairment in the value of the Company’s 50% investment in ESNE (recorded in the All
Other category), a limited liability company that owns an 80-megawatt, combined cycle, natural gas-
fired power plant in the town of North East, Pennsylvania; and

(cid:129) A $2.3 million death benefit gain on life insurance policies recognized in the Corporate category.

2008 Event

(cid:129) A $0.6 million gain in the All Other category associated with the sale of Horizon Power’s gas-powered

turbine.

2008 Compared with 2007

The Company’s earnings were $268.7 million in 2008 compared with earnings of $337.5 million in 2007.
As previously discussed, the Company presented its Canadian operations in the Exploration and Production
segment (in conjunction with the sale of SECI) as discontinued operations. The Company’s earnings from
continuing operations were $268.7 million in 2008 compared with $201.7 million in 2007. The Company’s
earnings from discontinued operations were $135.8 million in 2007. The increase in earnings from continuing
operations is primarily the result of higher earnings in the Exploration and Production and Utility segments and
the All Other category, slightly offset by lower earnings in the Corporate category and the Pipeline and Storage
and Energy Marketing segments, as shown in the table below. Earnings from continuing operations and
discontinued operations were impacted by the 2008 event discussed above and the following 2007 events:

2007 Events

(cid:129) A $120.3 million gain on the sale of SECI, which was completed in August 2007. This amount is included

in earnings from discontinued operations;

(cid:129) A $4.8 million benefit to earnings in the Pipeline and Storage segment due to the reversal of a reserve
established for all costs incurred related to the Empire Connector project recognized during June 2007;

(cid:129) A $1.9 million benefit to earnings in the Pipeline and Storage segment associated with the discontinu-

ance of hedge accounting for Empire’s interest rate collar; and

(cid:129) A $2.3 million benefit to earnings in the Energy Marketing segment related to the resolution of a

purchased gas contingency.

2009 Compared with 2008

Operating revenues for the Utility segment decreased $97.2 million in 2009 compared with 2008. This
decrease largely resulted from a $54.5 million decrease in off-system sales revenue (see discussion below), a
$33.6 million decrease in retail gas sales revenues, a $2.4 million decrease in transportation revenues, and a
$6.7 million decrease in other operating revenues.

The decrease in retail gas sales revenues of $33.6 million was largely a function of the recovery of lower gas
costs (subject to certain timing variations, gas costs are recovered dollar for dollar in revenues). The recovery of
lower gas costs resulted from a much lower cost of purchased gas. See further discussion of purchased gas below
under the heading “Purchased Gas.” The decrease in transportation revenues of $2.4 million was primarily due
to a 4.5 Bcf decrease in transportation throughput, largely the result of customer conservation efforts and the
poor economy.

In the New York jurisdiction, the NYPSC issued an order providing for an annual rate increase of
$1.8 million beginning December 28, 2007. As part of this rate order, a rate design change was adopted that
shifts a greater amount of cost recovery into the minimum bill amount, thus spreading the recovery of such costs
more evenly throughout the year. As a result of this rate order, retail and transportation revenues for 2009 were
$2.2 million lower than revenues for 2008.

The Utility segment had off-system sales revenues of $3.7 million and $58.2 million for 2009 and 2008,
respectively. Due to profit sharing with retail customers, the margins resulting from off-system sales are minimal
and there was not a material impact to margins in 2009 and 2008. The decrease in off-system sales revenue stems
from Order No. 717 (“Final Rule”), which was issued by the FERC on October 16, 2008. The Final Rule
seemingly held that a local distribution company making off-system sales on unaffiliated pipelines would be
engaging in “marketing” that would require compliance with the FERC’s standards of conduct. Accordingly,
pending clarification of this issue from the FERC, as of November 1, 2008, Distribution Corporation ceased off-
system sales activities. On October 15, 2009, the FERC released Order No. 717-A, which clarified that a local
distribution company making off-system sales of gas that has been transported on non-affiliated pipelines is not
subject to the standards of conduct. In light of and in reliance on this clarification, Distribution Corporation
determined that it may resume engaging in off-system sales on non-affiliated pipelines. Such off-system sales
resumed in November 2009.

The decrease in other operating revenues of $6.7 million is largely related to amounts recorded in 2008
pursuant to rate settlements approved by the NYPSC. In accordance with these settlements, Distribution
Corporation was allowed to utilize certain refunds from upstream pipeline companies and certain other credits
(referred to as the “cost mitigation reserve”) to offset certain specific expense items. In 2008, Distribution
Corporation utilized $5.6 million of the cost mitigation reserve, which increased other operating revenues, to
recover previous undercollections of pension expenses. In 2009, Distribution Corporation utilized only
$0.2 million of the cost mitigation reserve. The impact of this $5.4 million decrease in other operating
revenues was offset by an equal decrease to operation and maintenance expense (thus there is no earnings
impact).

33

2008 Compared with 2007

Operating revenues for the Utility segment increased $89.5 million in 2008 compared with 2007. This
increase largely resulted from a $48.5 million increase in off-system sales revenue (see discussion below), a
$25.6 million increase in retail gas sales revenues, an $11.3 million increase in transportation revenues, and a
$4.1 million increase in other operating revenues.

The increase in retail gas sales revenues for the Utility segment was largely a function of the recovery of
higher gas costs (subject to certain timing variations, gas costs are recovered dollar for dollar in revenues),
which more than offset the revenue impact of lower retail sales volumes, as shown in the table above. See further
discussion of purchased gas below under the heading “Purchased Gas.” This change was also affected by a base
rate increase in the Pennsylvania jurisdiction (effective January 2007) that increased operating revenues by
$4.0 million for 2008. The increase is included within both retail and transportation revenues in the table above.

In the New York jurisdiction, the NYPSC issued an order providing for an annual rate increase of
$1.8 million beginning December 28, 2007. As part of this rate order, a rate design change was adopted that
shifts a greater amount of cost recovery into the minimum bill amount, thus spreading the recovery of such costs
more evenly throughout the year. This rate design change resulted in lower retail and transportation revenues
(exclusive of the impact of higher gas costs) during the winter months compared to the prior year and higher
retail and transportation revenues in the spring and summer months compared to the prior year. On a
cumulative basis for 2008, the impact of this rate order has been to lower operating revenues by $1.4 million.
The increase in transportation revenues was also due to a 2.0 Bcf increase in transportation throughput, largely
the result of the migration of customers from retail sales to transportation service.

On November 17, 2006 the U.S. Court of Appeals vacated and remanded the FERC’s Order No. 2004
regarding affiliate standards of conduct, with respect to natural gas pipelines. The Court’s decision became
effective on January 5, 2007, and on January 9, 2007, the FERC issued Order No. 690, its Interim Rule, designed
to respond to the Court’s decision. In Order No. 690, as clarified by the FERC on March 21, 2007, the FERC
readopted, on an interim basis, certain provisions that existed prior to the issuance of Order No. 2004 that had
made it possible for the Utility segment to engage in certain off-system sales without triggering the adverse
consequences that would otherwise arise under the Order No. 2004 standards of conduct. As a result, the Utility
segment resumed engaging in off-system sales on non-affiliated pipelines as of May 2007, resulting in total off-
system sales revenues of $58.2 million and $9.8 million for 2008 and 2007, respectively. Due to profit sharing
with retail customers, the margins resulting from off-system sales are minimal and there was not a material
impact to margins in 2008 and 2007.

The increase in other operating revenues of $4.1 million is largely related to amounts recorded pursuant to
rate settlements approved by the NYPSC. In accordance with these settlements, Distribution Corporation was
allowed to utilize certain refunds from upstream pipeline companies and certain other credits (referred to as the
“cost mitigation reserve”) to offset certain specific expense items. In 2008, Distribution Corporation utilized
$5.6 million of the cost mitigation reserve, which increased other operating revenues, to recover previous
undercollections of pension expenses. The impact of that increase in other operating revenues was offset by an
equal amount of operation and maintenance expense (thus there is no earnings impact).

Purchased Gas

The cost of purchased gas is the Company’s single largest operating expense. Annual variations in
purchased gas costs are attributed directly to changes in gas sales volumes, the price of gas purchased and
the operation of purchased gas adjustment clauses.

Currently, Distribution Corporation has contracted for long-term firm transportation capacity with Supply
Corporation, Empire and six other upstream pipeline companies, for long-term gas supplies with a combination
of producers and marketers, and for storage service with Supply Corporation and three nonaffiliated companies.
In addition, Distribution Corporation satisfies a portion of its gas requirements through spot market purchases.
Changes in wellhead prices have a direct impact on the cost of purchased gas. Distribution Corporation’s
average cost of purchased gas, including the cost of transportation and storage, was $8.17 per Mcf in 2009, a

34

decrease of 27% from the average cost of $11.23 per Mcf in 2008. The average cost of purchased gas in 2008 was
12% higher than the average cost of $10.04 per Mcf in 2007. Additional discussion of the Utility segment’s gas
purchases appears under the heading “Sources and Availability of Raw Materials” in Item 1.

Earnings

2009 Compared with 2008

The Utility segment’s earnings in 2009 were $58.7 million, a decrease of $2.8 million when compared with

earnings of $61.5 million in 2008.

In the New York jurisdiction, earnings decreased by $3.0 million. This was primarily due to an increase in
interest expense ($2.9 million) stemming from the borrowing by the New York jurisdiction of Distribution
Corporation of a portion of the Company’s April 2009 debt issuance. The April 2009 debt was issued at a
significantly higher interest rate than the interest rates on debt that had matured in March 2009. The negative
earnings impact of the December 28, 2007 rate order discussed above ($1.4 million) and routine regulatory
adjustments ($0.7 million) also contributed to the decrease. The decrease was partially offset by a $2.6 million
overall reduction in operating expenses (mostly other post-retirement benefits and pension expense).

In the Pennsylvania jurisdiction, earnings increased by $0.2 million. This was primarily due to the positive
earnings impact of colder weather ($2.1 million), routine regulatory adjustments ($0.5 million) and lower
operating expenses ($0.9 million). A decrease in normalized usage per account ($2.3 million), a higher effective
tax rate ($1.4 million) and an increase in interest expense ($0.2 million) partially offset these increases. The
phrase “usage per account” refers to the average gas consumption per customer account after factoring out any
impact that weather may have had on consumption.

The impact of weather on the Utility segment’s New York rate jurisdiction is tempered by a weather
normalization clause (WNC). The WNC, which covers the eight-month period from October through May, has
had a stabilizing effect on earnings for the New York rate jurisdiction. In addition, in periods of colder than
normal weather, the WNC benefits the Utility segment’s New York customers. For 2009, the WNC reduced
earnings by approximately $0.2 million, as the weather was colder than normal. For 2008, the WNC preserved
earnings of approximately $2.5 million, as the weather was warmer than normal.

2008 Compared with 2007

The Utility segment’s earnings in 2008 were $61.5 million, an increase of $10.6 million when compared

with earnings of $50.9 million in 2007.

In the New York jurisdiction, earnings increased by $6.9 million. This was primarily due to a $3.6 million
overall decrease in operating expenses (mostly other post-retirement benefits and bad debt expense), higher
non-cash interest income on a pension-related regulatory asset ($2.6 million), a decrease in property, franchise,
and other taxes ($0.9 million), a decrease in depreciation expense ($0.8 million), lower income tax expense
($0.7 million), lower interest expense ($0.2 million), and increased usage per account ($0.5 million). The
impact of these items more than offset lower base rates due to the rate design change described above
($0.9 million), and routine regulatory adjustments that reduced earnings by $1.8 million.

In the Pennsylvania jurisdiction, earnings increased by $3.7 million. This was primarily due to a base rate
increase ($2.6 million) that became effective January 2007, an increase in normalized usage ($1.3 million), a
decrease in bad debt expense ($1.1 million), and a decrease in property, franchise, and other taxes ($0.3 mil-
lion). Warmer weather ($1.6 million) partially offset these increases.

The impact of weather on the Utility segment’s New York rate jurisdiction is tempered by a WNC. The
WNC, which covers the eight-month period from October through May, has had a stabilizing effect on earnings
for the New York rate jurisdiction. In addition, in periods of colder than normal weather, the WNC benefits the
Utility segment’s New York customers. In 2008 and 2007, the WNC preserved earnings of approximately
$2.5 million and $2.3 million, respectively, as the weather was warmer than normal.

2009 Compared with 2008

Operating revenues for the Pipeline and Storage segment increased $2.7 million in 2009 as compared with
2008. The increase was primarily due to a $15.6 million increase in transportation revenue primarily due to
higher revenues from the Empire Connector and new contracts for transportation service. Partially offsetting
this increase, efficiency gas revenues decreased $11.5 million (reported as a part of other revenue in the table
above). The majority of this decrease was due to significantly lower gas prices in 2009 as compared to 2008.
Under Supply Corporation’s tariff with suppliers, Supply Corporation is allowed to retain a set percentage of
shipper-supplied gas to cover compressor fuel costs and other operational purposes. To the extent that Supply
Corporation does not need all of the gas to cover such operational needs, it is allowed to keep the excess gas as
inventory. That inventory is later sold to customers. The excess gas that is retained as inventory represents
efficiency gas revenue to Supply Corporation.

2008 Compared with 2007

Operating revenues for the Pipeline and Storage segment increased $4.6 million in 2008 as compared with
2007. The majority of the increase was the result of increased transportation revenues ($3.7 million) due to the
fact that the Pipeline and Storage segment was able to renew existing contracts at higher rates due to favorable
market conditions for transportation service associated with storage. In addition, there were increased efficiency
gas revenues ($0.8 million) primarily due to higher gas prices in the current year.

Earnings

2009 Compared with 2008

The Pipeline and Storage segment’s earnings in 2009 were $47.4 million, a decrease of $6.7 million when
compared with earnings of $54.1 million in 2008. The decrease was primarily due to the earnings impact

36

associated with a decrease in efficiency gas revenues ($7.5 million), as discussed above. In addition, higher
interest expense ($5.1 million), higher depreciation expense ($1.5 million), and a decrease in the allowance for
funds used during construction ($2.0 million) also contributed to the decrease in earnings. The increase in
interest expense can be attributed to higher debt balances and a higher average interest rate on borrowings. The
increase in the average interest rate stems from the borrowing of a portion of the Company’s April 2009 debt
issuance. The increase in depreciation expense can be attributed primarily to a revision of accumulated
depreciation combined with the increased depreciation associated with placing the Empire Connector in service
in December 2008. The decease in the allowance for funds used during construction was due to completion of
the Empire Connector project in December 2008. Whereas the allowance for funds used during construction
related to the Empire Connector project was recorded throughout 2008, it was only recorded for three months
in 2009. These earnings decreases were partially offset by the earnings impact associated with higher trans-
portation revenues ($9.7 million), as discussed above.

2008 Compared with 2007

The Pipeline and Storage segment’s earnings in 2008 were $54.1 million, a decrease of $2.2 million when
compared with earnings of $56.4 million in 2007. The main factors contributing to this decrease were higher
operation and maintenance expenses ($6.1 million), primarily caused by the non-recurrence in 2008 of a
reversal of a reserve for preliminary survey costs related to the Empire Connector project during 2007
($4.8 million). In addition, there was a $1.9 million positive earnings impact during 2007 associated with
the discontinuance of hedge accounting for Empire’s interest rate collar that did not recur during 2008, and the
Pipeline and Storage segment experienced higher interest costs ($1.5 million). These earnings decreases were
offset by the earnings impact associated with higher transportation revenues ($2.4 million), an increase in the
allowance for funds used during construction ($4.2 million) and the earnings impact associated with higher
efficiency gas revenues ($0.5 million).

2009 Compared with 2008

Operating revenues from continuing operations for the Exploration and Production segment decreased
$84.0 million in 2009 as compared with 2008. Gas production revenue after hedging from continuing
operations decreased $47.6 million primarily due to a $2.11 per Mcf decrease in weighted average prices
after hedging. Gas production from continuing operations was virtually flat with the prior year as production

38

decreases in the Gulf Coast region were substantially offset by production increases in the Appalachian region.
The decrease in gas production from continuing operations that occurred in the Gulf Coast region (1,147 MMcf)
was a result of lingering shut-ins caused by Hurricanes Edouard, Gustav and Ike in September 2008. While
Seneca’s properties sustained only superficial damage from the hurricanes, two significant producing properties
were shut-in for a significant portion of the current fiscal year due to repair work on third party pipelines and
onshore processing facilities. One of the properties was back on line by March 31, 2009 and the other property
was back on line by the end of April 2009. The increase in gas production from continuing operations in the
Appalachian region of 1,066 MMcf resulted from additional wells drilled throughout fiscal 2008 that came on
line in 2009. Oil production revenue after hedging from continuing operations decreased $31.9 million due to a
$16.81 per barrel decrease in weighted average prices after hedging, which more than offset an increase in oil
production from continuing operations of 303,000 barrels (primarily from the West Coast and Gulf Coast
regions). In addition, there was a $5.9 million decrease in gross processing plant revenues from continuing
operations (net of eliminations) due to a reduction in the commodity prices of residual gas and liquids sold at
Seneca’s processing plants in the West Coast and Appalachian regions.

Refer to further discussion of derivative financial instruments in the “Market Risk Sensitive Instruments”

section that follows. Refer to the tables above for production and price information.

2008 Compared with 2007

Operating revenues from continuing operations for the Exploration and Production segment increased
$142.7 million in 2008 as compared with 2007. Oil production revenue after hedging from continuing
operations increased $83.3 million due primarily to a $30.07 per barrel increase in weighted average prices
after hedging, which more than offset a decrease in oil production of 174,000 barrels. Gas production revenue
after hedging from continuing operations increased $58.4 million due to a $1.80 per Mcf increase in weighted
average prices after hedging and a 2,501 MMcf increase in production from continuing operations. The increase
in gas production from continuing operations occurred primarily in the Appalachian region (1,714 MMcf),
consistent with increased drilling activity in the region. The Gulf Coast region also contributed significantly to
the increase in natural gas production from continuing operations (677 MMcf). Production from new fields in
2008 (primarily in the High Island area) outpaced declines in production from some existing fields, period to
period. Production in this region would have been higher if not for the hurricane activity during the month of
September 2008. As a result of hurricanes Edouard, Gustav and Ike, production was shut in for much of the
month of September, resulting in estimated lost production of approximately 804 MMcf of natural gas and 45
Mbbl of oil.

section that follows. Refer to the tables above for production and price information.

Earnings

2009 Compared with 2008

The Exploration and Production segment’s loss from continuing operations for 2009 was $10.2 million,
compared with earnings from continuing operations of $146.6 million for 2008, a decrease of $156.8 million.
The decrease in earnings is primarily the result of an impairment charge of $108.2 million, as discussed above.
In addition, lower crude oil prices, lower natural gas prices, and lower natural gas production decreased
earnings by $36.9 million, $30.6 million, and $0.3 million, respectively, while higher crude oil production
increased earnings by $16.1 million. Lower interest income ($5.5 million) and higher operating expenses
($1.7 million) further reduced earnings. In addition, there was a $3.8 million decrease in earnings caused by a
reduction in the commodity prices of residual gas and liquids sold at Seneca’s processing plants in the West
Coast and Appalachian regions. The decrease in interest income is due to lower interest rates and lower
temporary cash investment balances. The increase in operating expenses is due to an increase in bad debt
expense as a result of a customer’s bankruptcy filing, and higher personnel costs in the Appalachian region.
These earnings decreases were partially offset by lower interest expense ($5.4 million), lower lease operating
costs ($2.6 million), lower depletion expense ($0.9 million), and lower income tax expense ($4.2 million). The

39

decline in interest expense is primarily due to a lower average amount of debt outstanding. The reduction in
lease operating expenses is primarily due to a reduction in steam fuel costs in the West Coast region and lower
production taxes in the Gulf Coast region. The decrease in depletion is primarily due to a lower full cost pool
balance after the impairment charge taken during the quarter ended December 31, 2008.

2008 Compared with 2007

The Exploration and Production segment’s earnings from continuing operations for 2008 were $146.6 mil-
lion, an increase of $71.7 million when compared with earnings from continuing operations of $74.9 million for
2007. Higher crude oil prices, higher natural gas prices and higher natural gas production increased earnings by
$60.0 million, $26.2 million and $11.8 million, respectively, while lower crude oil production decreased
earnings by $5.8 million. Higher lease operating costs ($11.9 million), higher depletion expense ($9.1 million),
higher income tax expense ($1.1 million) and higher general and administrative and other operating expenses
($6.2 million) also negatively impacted earnings. Lower interest expense and higher interest income of
$6.6 million and $0.7 million, respectively, partially offset these decreases to earnings. The increase in lease
operating costs resulted from the start-up of production at the High Island 24L field in October 2007, higher
steaming costs in California, and an increase in costs associated with a higher number of producing properties in
Appalachia. The increase in depletion expense was caused by higher production and an increase in the
depletable base. The increase in general and administrative and other operating expenses resulted from an
increase in staffing and associated costs for the growing Appalachia division combined with the recognition of
actual plugging costs in excess of previously accrued amounts.

2009 Compared with 2008

Operating revenues for the Energy Marketing segment decreased $152.9 million in 2009 as compared with
2008. The decrease is primarily due to lower gas sales revenue, due to a lower average price of natural gas that
was recovered through revenues. This decline was somewhat offset by an increase in volume sold. The increase
in sales volume is largely attributable to colder weather as well as an increase in sales transactions undertaken at
the Niagara pipeline delivery point to offset certain basis risks that the Energy Marketing segment was exposed
to under certain fixed basis commodity purchase contracts for Appalachian production. Such offsetting
transactions had the effect of increasing revenue and volume sold with minimal impact to earnings.

2008 Compared with 2007

Operating revenues for the Energy Marketing segment increased $137.6 million in 2008 as compared with
2007. The increase is primarily due to higher gas sales revenue, as a result of an increase in the price of natural
gas that was recovered through revenues, coupled with an increase in volume sold. The increase in volume is

40

primarily attributable to an increase in volume sold to low-margin wholesale customers, as well as an increase in
the number of commercial and industrial customers served by the Energy Marketing segment. The increase in
volume also reflects certain sales transactions undertaken at the Niagara pipeline delivery point to offset certain
basis risks that the Energy Marketing segment was exposed to under certain fixed basis commodity purchase
contracts for Appalachian production. Such offsetting transactions had the effect of increasing revenue and
volume sold with minimal impact to earnings.

Earnings

2009 Compared with 2008

The Energy Marketing segment’s earnings in 2009 were $7.2 million, an increase of $1.3 million when
compared with earnings of $5.9 million in 2008. Higher margin of $1.5 million combined with lower operating
costs of $0.4 million (primarily due to a decline in bad debt expense) are responsible for the increase in earnings.
These increases were partially offset by higher income tax expense of $0.4 million in 2009 as compared to 2008.
The increase in margin was primarily driven by lower pipeline transportation fuel costs due to lower natural gas
commodity prices, an unfavorable pipeline imbalance resolution in fiscal 2008 that did not recur in fiscal 2009,
and improved average margins per Mcf, partially offset by higher pipeline reservation charges related to
additional storage capacity.

2008 Compared with 2007

The Energy Marketing segment’s earnings in 2008 were $5.9 million, a decrease of $1.8 million when
compared with earnings of $7.7 million in 2007. Higher operating costs of $1.1 million (primarily due to an
increase in bad debt expense) coupled with lower margin of $1.1 million are primarily responsible for the
decrease in earnings. A major factor in the margin decrease is the non-recurrence of a purchased gas expense
adjustment recorded during the quarter ended March 31, 2007. During that quarter, the Energy Marketing
segment reversed an accrual for $2.3 million of purchased gas expense due to a resolution of a contingency. The
increase in volume noted above, the profitable sale of certain gas held as inventory, and the marketing flexibility
that the Energy Marketing segment derives from its contracts for significant storage capacity partially offset the
margin decrease associated with the purchased gas adjustment.

ALL OTHER AND CORPORATE OPERATIONS

All Other and Corporate operations primarily includes the operations of Highland, Seneca’s Northeast
Division, Midstream Corporation, Horizon LFG, Horizon Power, former International segment activity and
corporate operations. Highland and Seneca’s Northeast Division market timber from their New York and
Pennsylvania land holdings, own two sawmill operations in northwestern Pennsylvania and process timber
consisting primarily of high quality hardwoods. Midstream Corporation is a Pennsylvania corporation formed
to build, own and operate natural gas processing and pipeline gathering facilities in the Appalachian region.
Horizon LFG owns and operates short-distance landfill gas pipeline companies. Horizon Power’s activity
primarily consists of equity method investments in Seneca Energy, Model City and ESNE. Horizon Power has a
50% ownership interest in each of these entities. The income from these equity method investments is reported
as Income from Unconsolidated Subsidiaries on the Consolidated Statements of Income. Seneca Energy and
Model City generate and sell electricity using methane gas obtained from landfills owned by outside parties.
ESNE generates electricity from an 80-megawatt, combined cycle, natural gas-fired power plant in North East,
Pennsylvania.

Earnings

2009 Compared with 2008

All Other and Corporate operations had a loss of $2.2 million in 2009, a decrease of $2.8 million compared
with earnings of $0.6 million for 2008. The decrease in earnings was largely attributable to lower margins from
lumber, log and timber rights sales ($2.5 million), lower margins from Horizon LFG ($1.6 million), lower
interest income ($0.6 million), lower income from Horizon Power’s investments in unconsolidated subsidiaries

41

($2.0 million), and higher interest expense ($3.1 million). The decrease in margins from lumber, log and timber
rights sales is a result of a decline in revenues due to unfavorable market conditions. The decrease in margins
from Horizon LFG is due to the decrease in the price of gas and lower volumes due to the poor economy. The
increase in interest expense was primarily the result of higher borrowings at a higher interest rate (mostly due to
the $250 million of 8.75% notes that were issued in April 2009). In addition, during 2009, ESNE, an
unconsolidated subsidiary of Horizon Power, recorded an impairment charge of $3.6 million. Horizon Power’s
50% share of the impairment was $1.8 million ($1.1 million on an after tax basis). In 2009, Horizon LFG
recorded an impairment charge of $4.6 million on its landfill gas assets ($2.8 million on an after-tax basis). Also,
Horizon Power recognized a gain on the sale of a turbine ($0.6 million) during 2008 that did not recur in 2009.
These earnings decreases were partially offset by lower operating costs ($4.9 million). In 2008, the proxy
contest with New Mountain Vantage GP, L.L.C. led to an increase in operating costs, which did not recur in
2009. In addition, lower income tax expense ($4.3 million) and a gain on life insurance policies held by the
Company ($2.3 million) further offset the earnings decrease.

The impairment charge of $4.6 million recorded by Horizon LFG during 2009 (as discussed above) was
comprised of a $2.6 million reduction in intangible assets related to long-term gas purchase contracts and a
$2.0 million reduction in property, plant and equipment. The impairment was recorded due to the loss of the
primary customer at a landfill gas site and the anticipated shut-down of the site. This impairment charge
reduced the recorded value of intangible assets and property, plant and equipment associated with this site to
zero at September 30, 2009.

The impairment charge of $3.6 million recorded by ESNE during 2009 (as discussed above) was driven by a
significant decrease in “run time” for the plant given the economic downturn and the resulting decrease in
demand for electric power.

2008 Compared with 2007

All Other and Corporate operations had earnings of $0.6 million in 2008, a decrease of $11.3 million
compared with earnings of $11.9 million for 2007. The positive earnings impact of higher income from
unconsolidated subsidiaries ($0.9 million) and a gain on the sale of a turbine by Horizon Power ($0.6 million)
were more than offset by higher operating costs ($5.9 million), higher income tax expense ($0.9 million), lower
interest income ($1.5 million) and lower margins from lumber, log and timber rights sales ($4.2 million). The
increase in operating costs is primarily the result of the proxy contest with New Mountain Vantage GP, L.L.C.
The decrease in margins from lumber, log and timber rights sales is a result of a decline in revenues due to
unfavorable market conditions and wet weather conditions that hampered harvesting. In addition, in 2007,
Seneca’s Northeast Division sold 3.1 million board feet of timber rights and recorded a gain of $1.6 million in
other revenues, which did not recur in 2008.

INTEREST INCOME

Interest income was $5.0 million lower in 2009 as compared to 2008. Lower cash investment balances in
the Exploration and Production segment and lower interest rates on such investments were the primary factors
contributing to this decrease.

Interest income was $9.3 million higher in 2008 as compared to 2007. The main reason for this increase
was a $4.0 million increase in interest income on a pension-related regulatory asset in the Utility segment’s New
York jurisdiction. The Exploration and Production segment also contributed $3.8 million to this increase as a
result of the investment of cash proceeds from the sale of SECI in August 2007.

OTHER INCOME

Other income was $0.8 million lower in 2009 as compared to 2008. This decrease is attributed to a
$1.7 million decrease in the allowance for funds used during construction in the Pipeline and Storage segment
associated with the Empire Connector project. Horizon Power recognized a $0.9 million pre-tax gain on the sale
of a turbine during 2008 that did not recur in 2009. These decreases were partially offset by a death benefit gain
on life insurance policies of $2.3 million recognized in the Corporate category during 2009.

42

Other income was $2.4 million higher in 2008 as compared to 2007. This increase is primarily attributed to
a $4.2 million increase in the allowance for funds used during construction in the Pipeline and Storage segment
associated with the Empire Connector project. It also reflects a $0.9 million pre-tax gain on the sale of a turbine
during 2008. These increases were partially offset by the non-recurrence of a death benefit gain on life insurance
proceeds of $1.9 million recognized in the Corporate category in 2007.

INTEREST CHARGES

Although most of the variances in Interest Charges are discussed in the earnings discussion by segment

above, the following is a summary on a consolidated basis:

Interest on long-term debt increased $9.3 million in 2009 as compared to 2008. The increase in 2009 was
primarily the result of a higher average amount of long-term debt outstanding combined with higher average
interest rates. In April 2009, the Company issued $250 million of 8.75% senior, unsecured notes due in May
2019. This increase was partially offset by the repayment of $100 million of 6% medium-term notes that
matured in March 2009.

Interest on long-term debt increased $1.7 million in 2008 as compared to 2007. The increase in 2008 was
primarily the result of a higher average amount of long-term debt outstanding. In April 2008, the Company
issued $300 million of 6.5% senior, unsecured notes due in April 2018. This increase was partially offset by the
repayment of $200 million of 6.303% medium-term notes that matured on May 27, 2008.

Other interest charges increased $3.6 million in 2009 compared to 2008. The increase in 2009 was
primarily caused by a $2.3 million increase in interest expense on regulatory deferrals (primarily deferred gas
costs) in the Utility segment’s New York jurisdiction combined with a $0.7 million decrease in the allowance for
borrowed funds used during construction related to the Empire Connector project.

Other interest charges decreased $2.2 million in 2008 compared to 2007. The decrease in 2008 was
primarily caused by a $1.7 million increase in the allowance for borrowed funds used during construction
related to the Empire Connector project.

OPERATING CASH FLOW

Internally generated cash from operating activities consists of net income available for common stock,
adjusted for non-cash expenses, non-cash income and changes in operating assets and liabilities. Non-cash
items include depreciation, depletion and amortization, impairment of oil and gas producing properties,
impairment of investment in partnership, deferred income taxes, income or loss from unconsolidated subsid-
iaries net of cash distributions and gain on sale of discontinued operations.

Cash provided by operating activities in the Utility and Pipeline and Storage segments may vary
substantially from year to year because of the impact of rate cases. In the Utility segment, supplier refunds,
over- or under-recovered purchased gas costs and weather may also significantly impact cash flow. The impact of
weather on cash flow is tempered in the Utility segment’s New York rate jurisdiction by its WNC and in the
Pipeline and Storage segment by the straight fixed-variable rate design used by Supply Corporation and Empire.

Cash provided by operating activities in the Exploration and Production segment may vary from period to
period as a result of changes in the commodity prices of natural gas and crude oil. The Company uses various
derivative financial instruments, including price swap agreements and futures contracts in an attempt to manage
this energy commodity price risk.

Net cash provided by operating activities totaled $609.4 million in 2009, an increase of $126.6 million
compared with the $482.8 million provided by operating activities in 2008. The increase is primarily due to the
timing of gas cost recovery in the Utility segment. As gas prices decreased significantly during 2009, the
Company’s Utility segment experienced an over-recovery of gas costs that is reflected in Amounts Payable to
Customers on the Company’s Consolidated Balance Sheet at September 30, 2009. At September 30, 2008, the

44

Company’s Utility segment was in an under-recovery position. It is expected that the over-recovery at
September 30, 2009 will be passed back to customers in 2010.

Net cash provided by operating activities totaled $482.8 million in 2008, an increase of $88.6 million
compared with the $394.2 million provided by operating activities in 2007. In the Utility segment, lower cash
payments for gas costs offset partially by lower cash receipts for retail and transportation services resulted in
higher cash provided by operations. In the Exploration and Production segment, cash provided by operations
increased due to higher cash receipts from the sale of oil and gas production, largely a result of higher
commodity prices. This increase in the Exploration and Production segment was partially offset by a decrease in
cash provided by operations that resulted from the sale of SECI, a discontinued operation, in August 2007. Cash
provided by operating activities from SECI was $0.3 million in 2007. Partially offsetting these increases, the
Energy Marketing segment experienced a decrease in cash provided by operations due to the timing of gas cost
recovery.

The majority of the Pipeline and Storage segment’s capital expenditures for 2009 and 2008 were related to
the Empire Connector project, which was placed into service on December 10, 2008, as well as for additions,
improvements, and replacements to this segment’s transmission and gas storage systems. The majority of the
Pipeline and Storage segment’s capital expenditures for 2007 were made for additions, improvements, and
replacements to this segment’s transmission and gas storage systems. The Empire Connector project was
completed for a cost of approximately $192 million. The Company capitalized Empire Connector project costs
of $27.3 million, $149.2 million and $15.5 million for the years ended September 30, 2009, 2008 and 2007,
respectively.

Exploration and Production

In 2009, the Exploration and Production segment’s capital expenditures were primarily well drilling and
completion expenditures and included approximately $18.3 million for the Gulf Coast region, substantially all
of which was for the off-shore program in the shallow waters of the Gulf of Mexico, $31.4 million for the West
Coast region and $138.6 million for the Appalachian region. These amounts included approximately
$24.2 million spent to develop proved undeveloped reserves.

In July 2009, the Company’s wholly-owned subsidiary in the Exploration and Production segment, Seneca,
purchased Ivanhoe Energy’s United States oil and gas operations for approximately $39.2 million in cash
(including cash acquired of $4.3 million). The cash acquired at acquisition includes $2.0 million held in escrow
at September 30, 2009. Seneca placed this amount in escrow as part of the purchase price, and in accordance
with the purchase agreement, this amount will remain in escrow for one year from the closing of the transaction
provided there are no pending disputes or actions regarding obligations and liabilities required to be satisfied or
discharged by Ivanhoe Energy. This purchase complements the segment’s existing oil producing assets in the
Midway Sunset Field in California. This acquisition was funded with cash on hand.

In 2008, the Exploration and Production segment’s capital expenditures were primarily well drilling and
completion expenditures and included approximately $63.6 million for the Gulf Coast region, substantially all
of which was for the off-shore program in the shallow waters of the Gulf of Mexico, $62.8 million for the West
Coast region and $65.8 million for the Appalachian region. These amounts included approximately
$25.4 million spent to develop proved undeveloped reserves. The Appalachian region capital expenditures
include $2.4 million for the purchase of storage facilities, buildings, and base gas from Supply Corporation, as
shown in the table above.

In 2007, the Exploration and Production segment’s capital expenditures were primarily well drilling and
completion expenditures and included approximately $66.2 million for the Gulf Coast region, substantially all
of which was for the off-shore program in the Gulf of Mexico, $41.4 million for the West Coast region and
$39.1 million for the Appalachian region. These amounts included approximately $30.3 million spent to
develop proved undeveloped reserves.

46

All Other and Corporate

In 2009, the majority of the All Other and Corporate category’s expenditures for long-lived assets were for
the construction of Midstream Corporation’s Covington Gathering System, as discussed below. Expenditures for
long-lived assets for 2009 also included a $1.3 million capital contribution made by NFG Midstream Processing,
LLC in the Whitetail Processing plant, as discussed below.

In 2008, the majority of the All Other and Corporate category’s expenditures for long-lived assets were for
construction of a lumber sorter for Highland’s sawmill operations that was placed into service in October 2007,
as well as for purchases of equipment for Highland’s sawmill and kiln operations. Additionally, Horizon Power
sold a gas-powered turbine in March 2008 that it had planned to use in the development of a co-generation
plant. Horizon Power received proceeds of $5.3 million and recorded a pre-tax gain of $0.9 million associated
with the sale.

In 2007, the All Other and Corporate category expenditures for long-lived assets included a $3.3 million
capital contribution to Seneca Energy by Horizon Power. Seneca Energy generates and sells electricity using
methane gas obtained from landfills owned by outside parties. Horizon Power funded its capital contributions
with short-term borrowings. Additionally, the All Other and Corporate category expenditures for long-lived
assets also were for the construction of two new kilns that were placed into service during the quarter ended
June 30, 2007, as well as construction of a lumber sorter for Highland’s sawmill operations.

(1) Includes estimated expenditures for the years ended September 30, 2010, 2011 and 2012 of approximately

$42 million, $56 million and $28 million, respectively, to develop proved undeveloped reserves.

Utility

Estimated capital expenditures for the Utility segment in 2010 will be concentrated in the areas of main and

service line improvements and replacements and, to a lesser extent, the purchase of new equipment.

Pipeline and Storage

Estimated capital expenditures for the Pipeline and Storage segment in 2010 will be concentrated on the
replacement of transmission and storage lines, the reconditioning of storage wells and improvements of
compressor stations.

In light of the growing demand for pipeline capacity to move natural gas from new wells being drilled in
Appalachia — specifically in the Marcellus Shale producing area — Supply Corporation and Empire are
actively pursuing several expansion projects. Supply Corporation is moving forward with two strategic
compressor horsepower expansions, both supported by signed precedent agreements with Appalachian pro-
ducers, designed to move anticipated Marcellus production gas to markets beyond Supply Corporation’s
pipeline system.

The first strategic horsepower expansion project involves new compression along Supply Corporation’s
Line N, increasing that line’s capacity into Texas Eastern’s Holbrook Station in southwestern Pennsylvania

47

(“Line N Expansion Project”). This project is designed and contracted for 150,000 Dth/day of firm transpor-
tation, and will allow anticipated Marcellus production located in the vicinity of Line N to flow south and access
markets off Texas Eastern’s system, with a projected in-service date of November 2011. Supply Corporation is in
the process of preparing an NGA Section 7(c) application to the FERC for approval of the Line N Expansion
Project. The preliminary cost estimate for the Line N Expansion Project is $23 million. The forecasted
expenditures for this project over the next three years are as follows: $0.9 million in 2010, $18.5 million in
2011, and $3.6 million in 2012. These expenditures are included as Pipeline and Storage estimated capital
expenditures in the table above. As of September 30, 2009, less than $0.1 million has been spent to study the
Line N Expansion Project, which has been included in preliminary survey and investigation charges and has
been fully reserved for at September 30, 2009.

The second strategic horsepower expansion project involves the addition of compression at Supply
Corporation’s existing interconnect with Tennessee Gas Pipeline at Lamont, Pennsylvania, with a projected in-
service date of May 2010 (“Lamont Project”). The Lamont Project is designed and contracted for 40,000 Dth/day
of firm transportation and will afford shippers a transportation path from their anticipated Marcellus production
located in Elk and Cameron Counties, Pennsylvania to markets attached to Tennessee Gas Pipeline’s 300 Line.
The Lamont Project will not require an NGA Section 7(c) application, and will instead be constructed under
Supply Corporation’s existing blanket construction certificate authority from the FERC. The preliminary cost
estimate for the Lamont Project is $6 million, all of which is forecasted to occur in 2010. These expenditures are
included as Pipeline and Storage estimated capital expenditures in the table above. As of September 30, 2009,
less than $0.1 million has been spent to study the Lamont Project, which has been included in preliminary
survey and investigation charges and has been fully reserved for at September 30, 2009.

In addition, Supply Corporation continues to actively pursue its largest planned expansion, the
West-to-East/Appalachian Lateral pipeline project. The Appalachian Lateral project is routed through areas
in Pennsylvania where producers are actively drilling and are seeking market access for their newly discovered
reserves. The Appalachian Lateral will complement Supply Corporation’s original West to East (“W2E”) project,
which was designed to transport Rockies gas supply from Clarington, Ohio to the Ellisburg/Leidy/Corning area.
The Appalachian Lateral will transport gas supply from Pennsylvania’s producing area to the Overbeck area of
Supply Corporation’s existing system, from which some of the facilities associated with the W2E project will
move the gas to eastern market points, including Leidy, Pennsylvania, and to interconnections with Millennium
and Empire at Corning, New York. Preliminary engineering routing analysis, project cost estimate and rate
design have been completed, and prospective shippers have been offered precedent agreements for their
consideration. This project will require an NGA Section 7(c) application, which Supply Corporation has not
filed. The capital cost of all phases of the Appalachian Lateral/W2E transportation projects is estimated to be in
the range of $750 million to $1 billion. As of September 30, 2009, approximately $0.6 million has been spent to
study the Appalachian Lateral/W2E transportation projects, which has been included in preliminary survey and
investigation charges and has been fully reserved for at September 30, 2009.

Supply Corporation anticipates the development of the W2E/Appalachian Lateral project will occur in
phases, and based on requests from the Marcellus producing community for transportation service commencing
as early as 2011, Supply Corporation began a binding Open Season on August 26, 2009. This Open Season
offered transportation capacity on two initial phases (“Phase I” and “Phase II”) of the W2E pipeline project. The
capital cost of these two phases is estimated to be $257 million. Phase I is designed to transport approximately
200,000 Dth/day from the Marcellus producing area through a new 32-mile pipeline to be constructed through
Elk, Cameron, and Clinton Counties to the Leidy Hub, with an anticipated in-service date of late 2011. Phase II,
with a late 2012 projected in-service date, consists of an additional 50 miles of new pipeline and compression
extending through Clearfield and Jefferson Counties to Supply Corporation’s Line K system and would provide
additional transportation capacity of at least 300,000 Dth/day. The forecasted expenditures for Phase I and
Phase II of this project over the next three years are as follows: $6.0 million in 2010, $108.0 million in 2011, and
$143.0 million in 2012. These expenditures are included as Pipeline and Storage estimated capital expenditures
in the table above.

This binding Open Season concluded on October 8, 2009 with significant participation by Marcellus
producers. Supply Corporation received binding requests for 175,000 Dth/day of firm transportation capacity

48

and expects to execute the signed precedent agreements submitted by those Marcellus producers. Supply
Corporation is pursuing post-Open Season capacity requests for the remaining Phase I and Phase II capacity and
expects to continue marketing efforts for all sections of the W2E and Appalachian Lateral projects. The timeline
associated with the W2E and Appalachian Lateral projects will depend on market development.

In conjunction with the Appalachian Lateral and W2E transportation projects, Supply Corporation plans
to develop new storage capacity by expanding certain of its existing storage facilities. The expansion of these
fields could provide incremental storage capacity of approximately 8.5 MMDth and incremental withdrawal
deliverability of up to 121 MDth of natural gas per day, with service commencing in early 2013. Supply
Corporation expects that the availability of this incremental storage capacity will complement the Appalachian
Lateral/W2E pipeline transportation projects and help balance the increasing flow of Appalachian and Rockies
gas supply through the western Pennsylvania area, and the growing demand for gas on the east coast. This
storage expansion project will require an NGA Section 7(c) application, which Supply Corporation has not yet
filed. Preliminary cost estimates for the storage expansion project is $78 million. The forecasted expenditures
for this project over the next three years are as follows: $0.4 million in 2010, $0.2 million in 2011, and
$67.1 million in 2012. These expenditures are included as Pipeline and Storage estimated capital expenditures
in the table above. As of September 30, 2009, approximately $1.0 million has been spent to study the storage
expansion project, which has been included in preliminary survey and investigation charges and has been fully
reserved for at September 30, 2009. The timeline associated with the W2E and Appalachian Lateral projects and
any related storage development will depend on market development.

On October 1, 2009, Empire posted an Open Season for an expansion project that will provide at least
200,000 Dth/day of incremental firm transportation capacity from anticipated Marcellus production at new and
existing interconnection(s) along its recently completed Empire Connector line and along a proposed 16-mile
24” pipeline extension into Tioga County, Pennsylvania. Empire’s preliminary cost estimate for the Tioga
County Extension Project is approximately $43 million. This project would enable Marcellus producers to
deliver their gas at existing Empire interconnections with Millennium Pipeline at Corning, New York, with
TransCanada Pipeline at Chippawa, and with utility and power generation markets along its path, as well as to a
planned new interconnection with Tennessee Gas Pipeline’s 200 Line (Zone 5) in Ontario County, New York.
Empire completed a non-binding Open Season on October 23, 2009 for capacity in the Tioga County Extension
Project, and is in the process of negotiating binding precedent agreements with shippers who participated in the
Open Season, representing more than adequate capacity to support the project facilities. Following successful
negotiations, Empire will file an NGA Section 7(c) application with the FERC for approval of this project, and
anticipates that these facilities will be placed in-service on or after September 1, 2011. The forecasted
expenditures for this project over the next two years are as follows: $2.0 million in 2010 and $41.0 million
in 2011. These expenditures are included as Pipeline and Storage estimated capital expenditures in the table
above. As of September 30, 2009, no preliminary survey and investigation charges had been expended on this
project, but those activities began in October of 2009 and will be fully reserved in the periods they occur. The
timeline associated with the Tioga County Extension Project will depend on the completion of shipper
precedent agreements.

The Company anticipates financing the Line N Expansion Project, the Lamont Project, Phase I and Phase II
of the W2E/Appalachian Lateral project, the storage expansion project, and the Tioga County Extension Project,
all of which are discussed above, with a combination of cash from operations, short-term debt, and long-term
debt.

Exploration and Production

Estimated capital expenditures in 2010 for the Exploration and Production segment include approximately
$14.0 million for the Gulf Coast region, substantially all of which is for the off-shore program in the Gulf of
Mexico, $17.0 million for the West Coast region and $224.0 million for the Appalachian region. The Company
anticipates drilling 55 to 75 gross wells in the Marcellus Shale during 2010.

Estimated capital expenditures in 2011 for the Exploration and Production segment include approximately
$5.0 million for the Gulf Coast region, substantially all of which is for the off-shore program in the Gulf of

49

Mexico, $27.0 million for the West Coast region and $385.0 million for the Appalachian region. The Company
anticipates drilling 100 to 130 gross wells in the Marcellus Shale during 2011.

Estimated capital expenditures in 2012 for the Exploration and Production segment include approximately
$12.0 million for the Gulf Coast region, substantially all of which is for the off-shore program in the Gulf of
Mexico, $41.0 million for the West Coast region and $444.0 million for the Appalachian region. The Company
anticipates drilling 120 to 150 gross wells in the Marcellus Shale during 2012.

All Other and Corporate

Estimated capital expenditures in 2010 for the All Other and Corporate category will primarily be for the
construction of anticipated gathering systems, including the construction of Midstream Corporation’s Cov-
ington Gathering System, as discussed below.

NFG Midstream Covington, LLC, a wholly owned subsidiary of Midstream Corporation, is constructing a
gathering system in Tioga County, Pennsylvania. The project, called the Covington Gathering System, is to be
constructed in two phases. The first phase was completed and placed in service in November 2009. The second
phase is anticipated to be placed in service in 2010. When completed, the system will consist of approximately
15 miles of gathering system at a cost of $15 million to $18 million. As of September 30, 2009, the Company has
spent approximately $8.1 million in costs related to this project.

NFG Midstream Processing, LLC, another wholly owned subsidiary of Midstream Corporation, has a 35%
ownership in the Whitetail Processing Plant. The plant is currently under construction with completion
expected in the fall of 2009. The total project cost is estimated at $4 million. Once completed, the plant will
extract natural gas liquids from local production. As of September 30, 2009, the Company invested $1.3 million
related to the construction of the plant.

The Company anticipates funding the Midstream Corporation projects with cash from operations and/or

short-term borrowings.

The Company continuously evaluates capital expenditures and investments in corporations, partnerships, and
other business entities. The amounts are subject to modification for opportunities such as the acquisition of attractive
oil and gas properties, timber or natural gas storage facilities and the expansion of natural gas transmission line
capacities. While the majority of capital expenditures in the Utility segment are necessitated by the continued need
for replacement and upgrading of mains and service lines, the magnitude of future capital expenditures or other
investments in the Company’s other business segments depends, to a large degree, upon market conditions.

FINANCING CASH FLOW

The Company did not have any outstanding short-term notes payable to banks or commercial paper at
September 30, 2009. However, the Company continues to consider short-term debt (consisting of short-term
notes payable to banks and commercial paper) an important source of cash for temporarily financing capital
expenditures and investments in corporations and/or partnerships, gas-in-storage inventory, unrecovered
purchased gas costs, margin calls on derivative financial instruments, exploration and development expendi-
tures, repurchases of stock, and other working capital needs. Fluctuations in these items can have a significant
impact on the amount and timing of short-term debt. As for bank loans, the Company maintains a number of
individual uncommitted or discretionary lines of credit with certain financial institutions for general corporate
purposes. Borrowings under these lines of credit are made at competitive market rates. These credit lines, which
aggregate to $420.0 million, are revocable at the option of the financial institutions and are reviewed on an
annual basis. The Company anticipates that these lines of credit will continue to be renewed, or replaced by
similar lines. The total amount available to be issued under the Company’s commercial paper program is
$300.0 million. The commercial paper program is backed by a syndicated committed credit facility totaling
$300.0 million that extends through September 30, 2010.

Under the Company’s committed credit facility, the Company has agreed that its debt to capitalization ratio
will not exceed .65 at the last day of any fiscal quarter through September 30, 2010. At September 30, 2009, the
Company’s debt to capitalization ratio (as calculated under the facility) was .44. The constraints specified in the

50

committed credit facility would permit an additional $1.7 billion in short-term and/or long-term debt to be
outstanding (further limited by the indenture covenants discussed below) before the Company’s debt to
capitalization ratio would exceed .65. If a downgrade in any of the Company’s credit ratings were to occur,
access to the commercial paper markets might not be possible. However, the Company expects that it could
borrow under its committed credit facility, uncommitted bank lines of credit or rely upon other liquidity
sources, including cash provided by operations. At September 30, 2009, the Company’s long-term debt ratings
were: BBB (S&P), Baa1 (Moody’s Investor Service), and A- (Fitch Ratings Service). At September 30, 2009, the
Company’s commercial paper ratings were: A-2 (S&P), P-2 (Moody’s Investor Service), and F2 (Fitch Ratings
Service).

Under the Company’s existing indenture covenants, at September 30, 2009, the Company would have been
permitted to issue up to a maximum of $435.0 million in additional long-term unsecured indebtedness at then
current market interest rates in addition to being able to issue new indebtedness to replace maturing debt. The
Company’s present liquidity position is believed to be adequate to satisfy known demands. However, if the
Company were to experience another impairment of oil and gas properties in the future, it is possible that these
indenture covenants would restrict the Company’s ability to issue additional long-term unsecured indebtedness.
This would not preclude the Company from issuing new indebtedness to replace maturing debt.

The Company’s 1974 indenture, pursuant to which $99.0 million (or 7.9%) of the Company’s long-term
debt (as of September 30, 2009) was issued, contains a cross-default provision whereby the failure by the
Company to perform certain obligations under other borrowing arrangements could trigger an obligation to
repay the debt outstanding under the indenture. In particular, a repayment obligation could be triggered if the
Company fails (i) to pay any scheduled principal or interest on any debt under any other indenture or
agreement, or (ii) to perform any other term in any other such indenture or agreement, and the effect of the
failure causes, or would permit the holders of the debt to cause, the debt under such indenture or agreement to
become due prior to its stated maturity, unless cured or waived.

The Company’s $300.0 million committed credit facility also contains a cross-default provision whereby
the failure by the Company or its significant subsidiaries to make payments under other borrowing arrange-
ments, or the occurrence of certain events affecting those other borrowing arrangements, could trigger an
obligation to repay any amounts outstanding under the committed credit facility. In particular, a repayment
obligation could be triggered if (i) the Company or any of its significant subsidiaries fail to make a payment
when due of any principal or interest on any other indebtedness aggregating $20.0 million or more, or (ii) an
event occurs that causes, or would permit the holders of any other indebtedness aggregating $20.0 million or
more to cause, such indebtedness to become due prior to its stated maturity. As of September 30, 2009, the
Company had no debt outstanding under the committed credit facility.

The Company’s embedded cost of long-term debt was 6.95% at September 30, 2009 and 6.5% at
September 30, 2008. Refer to “Interest Rate Risk” in this Item for a more detailed breakdown of the Company’s
embedded cost of long-term debt.

In April 2008, the Company issued $300.0 million of 6.50% senior, unsecured notes in a private placement
exempt from registration under the Securities Act of 1933. In February 2009, the Company exchanged the notes
for economically identical notes registered under the Securities Act of 1933. The notes have a term of 10 years,
with a maturity date in April 2018. The holders of the notes may require the Company to repurchase their notes
at a price equal to 101% of the principal amount in the event of both a change in control and a ratings downgrade
to a rating below investment grade. The Company used $200.0 million of the proceeds of the issuance to refund
$200.0 million of 6.303% medium-term notes that matured on May 27, 2008.

In April 2009, the Company issued $250.0 million of 8.75% notes due in March 2019. After deducting
underwriting discounts and commissions, the net proceeds to the Company amounted to $247.8 million. These
notes were registered under the Securities Act of 1933. The holders of the notes may require the Company to
repurchase their notes at a price equal to 101% of the principal amount in the event of both a change in control
and a ratings downgrade to a rating below investment grade. The proceeds of this debt issuance were used for
general corporate purposes, including to replenish cash that was used to pay the $100 million due at the
maturity of the Company’s 6.0% medium-term notes on March 1, 2009. After this debt issuance, the Company’s

51

embedded cost of long-term debt increased from 6.5% to 6.95%. If the Company were to issue long-term debt
today, its borrowing costs might be expected to be in the range of 6.0% to 7.0% depending on their maturity date.

On December 8, 2005, the Company’s Board of Directors authorized the Company to implement a share
repurchase program, whereby the Company could repurchase outstanding shares of common stock, up to an
aggregate amount of eight million shares in the open market or through privately negotiated transactions. The
Company completed the repurchase of the eight million shares during 2008 for a total program cost of
$324.2 million (of which 4,165,122 shares were repurchased during the year ended September 30, 2008 for
$191.0 million). In September 2008, the Company’s Board of Directors authorized the repurchase of an
additional eight million shares of the Company’s common stock. Under this new authorization, the Company
repurchased 1,028,981 shares for $46.0 million through September 17, 2008. The Company, however, stopped
repurchasing shares after September 17, 2008 in light of the unsettled nature of the credit markets. Such
repurchases may resume in the future. The share repurchases mentioned above were funded with cash provided
by operating activities and/or through the use of the Company’s lines of credit.

The Company may issue debt or equity securities in a public offering or a private placement from time to
time. The amounts and timing of the issuance and sale of debt or equity securities will depend on market
conditions, indenture requirements, regulatory authorizations and the capital requirements of the Company.

OFF-BALANCE SHEET ARRANGEMENTS

The Company has entered into certain off-balance sheet financing arrangements. These financing arrange-
ments are primarily operating leases. The Company’s consolidated subsidiaries have operating leases, the
majority of which are with the Utility and the Pipeline and Storage segments, having a remaining lease
commitment of approximately $27.8 million. These leases have been entered into for the use of buildings,
vehicles, construction tools, meters and other items and are accounted for as operating leases.

The Company has other long-term obligations recorded on its Consolidated Balance Sheets that are not
reflected in the table above. Such long-term obligations include pension and other post-retirement liabilities,
asset retirement obligations, deferred income tax liabilities, various regulatory liabilities, derivative financial
instrument liabilities and other deferred credits (the majority of which consist of liabilities for a non-qualified
benefit plan, deferred compensation liabilities, environmental liabilities, workers compensation liabilities and
liabilities for income tax uncertainties).

52

The Company has made certain other guarantees on behalf of its subsidiaries. The guarantees relate
primarily to: (i) obligations under derivative financial instruments, which are included on the Consolidated
Balance Sheets in accordance with the authoritative guidance (see Item 7, MD&A under the heading “Critical
Accounting Estimates — Accounting for Derivative Financial Instruments”); (ii) NFR obligations to purchase
gas or to purchase gas transportation/storage services where the amounts due on those obligations each month
are included on the Consolidated Balance Sheets as a current liability; and (iii) other obligations which are
reflected on the Consolidated Balance Sheets. The Company believes that the likelihood it would be required to
make payments under the guarantees is remote, and therefore has not included them in the table above.

OTHER MATTERS

In addition to the environmental and other matters discussed in this Item 7 and in Item 8 at Note I —
Commitments and Contingencies, the Company is involved in other litigation and regulatory matters arising in
the normal course of business. These other matters may include, for example, negligence claims and tax,
regulatory or other governmental audits, inspections, investigations or other proceedings. These matters may
involve state and federal taxes, safety, compliance with regulations, rate base, cost of service and purchased gas
cost issues, among other things. While these normal-course matters could have a material effect on earnings and
cash flows in the period in which they are resolved, they are not expected to change materially the Company’s
present liquidity position, nor are they expected to have a material adverse effect on the financial condition of
the Company.

The Company has a tax-qualified, noncontributory defined-benefit retirement plan (Retirement Plan) that
covers a majority of the Company’s employees. The Company has been making contributions to the Retirement
Plan over the last several years and anticipates that it will continue making contributions to the Retirement Plan.
During 2009, the Company contributed $16.0 million to the Retirement Plan. The Company anticipates that the
annual contribution to the Retirement Plan in 2010 will be in the range of $20.0 million to $30.0 million. It is
likely that the Company will have to fund larger amounts to the Retirement Plan subsequent to 2010 in order to
be in compliance with the Pension Protection Act of 2006. The Company expects that all subsidiaries having
employees covered by the Retirement Plan will make contributions to the Retirement Plan. The funding of such
contributions will come from amounts collected in rates in the Utility and Pipeline and Storage segments or
through short-term borrowings or through cash from operations.

The Company provides health care and life insurance benefits (other post-retirement benefits) for a
majority of its retired employees. The Company has established VEBA trusts and 401(h) accounts for its other
post-retirement benefits. The Company has been making contributions to its VEBA trusts and 401(h) accounts
over the last several years and anticipates that it will continue making contributions to the VEBA trusts and
401(h) accounts. During 2009, the Company contributed $25.5 million to its VEBA trusts and 401(h) accounts.
The Company anticipates that the annual contribution to its VEBA trusts and 401(h) accounts in 2010 will be in
the range of $25.0 million to $30.0 million. The funding of such contributions will come from amounts
collected in rates in the Utility and Pipeline and Storage segments.

As of September 30, 2009, the Company recorded a deferred tax asset relating to a federal net operating loss
carryover of $25.1 million. This carryover, which is available as a result of an acquisition, expires in varying
amounts between 2023 and 2029. Although this loss carryover is subject to certain annual limitations, no
valuation allowance was recorded because of management’s determination that the amount will be fully utilized
during the carryforward period.

MARKET RISK SENSITIVE INSTRUMENTS

Energy Commodity Price Risk

The Company, in its Exploration and Production segment, Energy Marketing segment and Pipeline and
Storage segment, uses various derivative financial instruments (derivatives), including price swap agreements
and futures contracts, as part of the Company’s overall energy commodity price risk management strategy.
Under this strategy, the Company manages a portion of the market risk associated with fluctuations in the price

53

of natural gas and crude oil, thereby attempting to provide more stability to operating results. The Company has
operating procedures in place that are administered by experienced management to monitor compliance with
the Company’s risk management policies. The derivatives are not held for trading purposes. The fair value of
these derivatives, as shown below, represents the amount that the Company would receive from, or pay to, the
respective counterparties at September 30, 2009 to terminate the derivatives. However, the tables below and the
fair value that is disclosed do not consider the physical side of the natural gas and crude oil transactions that are
related to the financial instruments.

Beginning in fiscal 2009, the Company adopted the authoritative guidance for fair value measurements. In
accordance with the adoption of this guidance, the Company has identified certain inputs used to recognize fair
value as Level 3 (unobservable inputs). The Level 3 derivative assets relate to oil swap agreements used to hedge
forecasted sales at a specific location (southern California). The Company’s internal model that is used to
calculate fair value applies a historical basis differential (between the sales locations and NYMEX) to a forward
NYMEX curve because there is not a forward curve specific to this sales location. Given the high level of
historical correlation between NYMEX prices and prices at this sales location, the Company does not believe
that the fair value recorded by the Company would be significantly different from what it expects to receive
upon settlement. The fair value of the Level 3 derivative assets was reduced by $0.7 million based upon the
Company’s assessment of counterparty credit risk. The Company applied default probabilities to the anticipated
cash flows that it was expecting from its counterparties to calculate the credit reserve.

The Level 3 assets amount to $27.0 million at September 30, 2009 and represent 60.2% of the Derivative
Financial Instruments Assets or 5.9% of the Total Assets as shown in Item 8 at Note F — Fair Value
Measurements at September 30, 2009.

During fiscal 2009, the Company transferred $8.1 million of derivative assets from Level 3 assets to Level 2
assets. The majority of these assets related to natural gas swaps on southern California natural gas production.
The Company also transferred $0.8 million of derivative liabilities from Level 3 liabilities to Level 2 liabilities.
These liabilities related to certain natural gas swaps on Gulf of Mexico natural gas production. These transfers
occurred because the Company was able to obtain and utilize forward-looking, observable basis differential
information for the hedges at these locations.

The Company uses the crude oil swaps classified as Level 3 to hedge against the risk of declining
commodity prices and not as speculative investments. Gains or losses related to these Level 3 derivative assets
(including any reduction for credit risk) are deferred until the hedged commodity transaction occurs in
accordance with the provisions of the existing guidance for derivative instruments and hedging activities.

The increase in the net fair value of the Level 3 positions from October 1, 2008 to September 30, 2009, as
shown in Item 8 at Note F, was attributable to a significant decrease in the commodity price of crude oil during
that period. The Company believes that these fair values reasonably represent the amounts that the Company
would realize upon settlement based on commodity prices that were present at September 30, 2009.

The following tables disclose natural gas and crude oil price swap information by expected maturity dates
for agreements in which the Company receives a fixed price in exchange for paying a variable price as quoted in
various national natural gas publications or on the NYMEX. Notional amounts (quantities) are used to calculate
the contractual payments to be exchanged under the contract. The weighted average variable prices represent
the weighted average settlement prices by expected maturity date as of September 30, 2009. At September 30,
2009, the Company had not entered into any natural gas or crude oil price swap agreements extending beyond
2012.

At September 30, 2009, the Company would have received from its respective counterparties an aggregate
of approximately $10.4 million to terminate the natural gas price swap agreements outstanding at that date. The
Company would have received from its respective counterparties an aggregate of approximately $27.0 million to
terminate the crude oil price swap agreements outstanding at September 30, 2009.

At September 30, 2008, the Company had natural gas price swap agreements covering 15.1 Bcf at a
weighted average fixed rate of $9.69 per Mcf. The Company also had crude oil price swap agreements covering
1,920,000 bbls at a weighted average fixed rate of $90.50 per bbl.

The following table discloses the net contract volume purchased (sold), weighted average contract prices
and weighted average settlement prices by expected maturity date for futures contracts used to manage natural
gas price risk. At September 30, 2009, the Company held no futures contracts with maturity dates extending
beyond 2012.

(1) The Energy Marketing segment has purchased 11 futures contracts (1 contract = 2,500 Dth) for 2012.

At September 30, 2009, the Company had long (purchased) futures contracts covering 11.6 Bcf of gas
extending through 2012 at a weighted average contract price of $6.37 per Mcf and a weighted average settlement
price of $6.07 per Mcf. They are accounted for as fair value hedges and are used by the Company’s Energy
Marketing segment to hedge against rising prices, a risk to which this segment is exposed to due to the fixed
price gas sales commitments that it enters into with residential, commercial and industrial customers. The
Company would have had to pay $3.5 million to terminate these futures contracts at September 30, 2009.

At September 30, 2009, the Company had short (sold) futures contracts covering 6.7 Bcf of gas extending
through 2011 at a weighted average contract price of $7.37 per Mcf and a weighted average settlement price of
$6.07 per Mcf. Of this amount, 5.8 Bcf is accounted for as cash flow hedges as these contracts relate to the
anticipated sale of natural gas by the Energy Marketing segment. The remaining 0.9 Bcf is accounted for as fair
value hedges used to hedge against falling prices, a risk to which the Energy Marketing segment is exposed to
due to the fixed price gas purchase commitments that it enters into with its natural gas suppliers. The Company
would have received $8.7 million to terminate these futures contracts at September 30, 2009.

At September 30, 2008, the Company had futures contracts covering 2.4 Bcf (net long position) at a

weighted average contract price of $9.99 per Mcf.

The Company may be exposed to credit risk on any of the derivative financial instruments that are in a gain
position. Credit risk relates to the risk of loss that the Company would incur as a result of nonperformance by
counterparties pursuant to the terms of their contractual obligations. To mitigate such credit risk, management

55

performs a credit check, and then on a quarterly basis monitors counterparty credit exposure. The majority of
the Company’s counterparties are financial institutions and energy traders. The Company has over-the-counter
swap positions with ten counterparties. At September 30, 2009, the Company had derivative financial
instruments that were in gain positions with eight of the counterparties. The Company had derivative financial
instruments that were in loss positions with the other two counterparties. The Company had $26.6 million of
credit exposure with one counterparty (which is rated A1 (Moody’s Investor Service), A (S&P), and A+ (Fitch
Ratings Service) as of September 30, 2009). On average for those financial instruments that were in a gain
position, the Company had $1.8 million of credit exposure per counterparty with the other seven counterparties
that were in a gain position. The Company had not received any collateral from the counterparties at
September 30, 2009 since the Company’s gain position on such derivative financial instruments had not
exceeded the established thresholds at which the counterparties would be required to post collateral.

As of September 30, 2009, eight of the ten counterparties to the Company’s outstanding derivative
instrument contracts (specifically the over-the-counter swaps) had a common credit-risk-related contingency
feature. In the event the Company’s credit rating increases or falls below a certain threshold (the lower of the
S&P or Moody’s Debt Rating), the available credit extended to the Company would either increase or decrease.
A decline in the Company’s credit rating, in and of itself, would not cause the Company to be required to
increase the level of its hedging collateral deposits (in the form of cash deposits, letters of credit or treasury debt
instruments). If the Company’s outstanding derivative instrument contracts were in a liability position and the
Company’s credit
then additional hedging collateral deposits would be required.
At September 30, 2009, these credit-risk related contingency features were not triggered since the Company
had assets of $37.9 million related to derivative financial instruments with the eight counterparties.

rating declined,

For its exchange traded futures contracts, which are in an asset position, the Company had paid
$0.8 million in hedging collateral as of September 30, 2009. As these are exchange traded futures contracts,
there are no specific credit-risk related contingency features. The Company posts hedging collateral based on
open positions (i.e. those positions that have been settled for cash) and margin requirements. (This is discussed
in Note A under Hedging Collateral Deposits.)

Interest Rate Risk

The following table presents the principal cash repayments and related weighted average interest rates by
expected maturity date for the Company’s long-term fixed rate debt as well as the other long-term debt of certain
of the Company’s subsidiaries. The interest rates for the variable rate debt are based on those in effect at

RATE AND REGULATORY MATTERS

Utility Operation

Base rate adjustments in both the New York and Pennsylvania jurisdictions do not reflect the recovery of
purchased gas costs. Such costs are recovered through operation of the purchased gas adjustment clauses of the
appropriate regulatory authorities.

New York Jurisdiction

Customer delivery rates charged by Distribution Corporation’s New York division were established in a rate
order issued on December 21, 2007 by the NYPSC. The rate order approved a revenue increase of $1.8 million

56

annually, together with a surcharge that would collect up to $10.8 million to recover expenses for implemen-
tation of an efficiency and conservation incentive program. The rate order further provided for a return on
equity of 9.1%. In connection with the efficiency and conservation program, the rate order also adopted
Distribution Corporation’s proposed revenue decoupling mechanism. The revenue decoupling mechanism, like
others, “decouples” revenues from throughput by enabling the Company to collect from small volume
customers its allowed margin on average weather normalized usage per customer. The effect of the revenue
decoupling mechanism is to render the Company financially indifferent to throughput decreases resulting from
conservation. The Company surcharges or credits any difference from the average weather normalized usage per
customer account. The surcharge or credit is calculated to recover total margin for the most recent twelve-
month period ending December 31, and is applied to customer bills annually, beginning March 1st.

On April 18, 2008, Distribution Corporation filed an appeal with Supreme Court, Albany County, seeking
review of the rate order. The appeal contends that portions of the rate order should be invalidated because they
fail to meet the applicable legal standard for agency decisions. Among the issues challenged by the Company are
the reasonableness of the NYPSC’s disallowance of expense items and the methodology used for calculating rate
of return, which the appeal contends understated the Company’s cost of equity. Briefs were filed and oral
argument was held on October 14, 2009. The Company cannot predict the outcome of the appeal at this time.

On April 7, 2009, the Governor of the State of New York signed into law an amendment to the Public
Service Law increasing the allowed utility assessment from the current rate of one-third of one percent to one
percent of a utility’s in-state gross operating revenue, together with a temporary surcharge equal, as applied, to
an additional one percent of the utility’s gross operating revenue. As a result of this amendment, Distribution
Corporation’s New York Division paid a total assessment of $26.2 million during fiscal 2009, of which
$22.9 million was labeled as the temporary surcharge. The NYPSC, in a generic proceeding initiated for the
purpose of implementing the amended law, has authorized the recovery, through rates, of the full cost of the
increased assessment. The assessment is currently being applied to customer bills.

Pennsylvania Jurisdiction

Distribution Corporation currently does not have a rate case on file with the PaPUC. Distribution
Corporation’s current tariff in its Pennsylvania jurisdiction was last approved by the PaPUC on November 30,
2006 as part of a settlement agreement that became effective January 1, 2007.

Pipeline and Storage

Supply Corporation currently does not have a rate case on file with the FERC. The rate settlement approved
by the FERC on February 9, 2007 requires Supply Corporation to make a general rate filing to be effective
December 1, 2011, and bars Supply Corporation from making a general rate filing before then, with some
exceptions specified in the settlement.

Empire’s new facilities (the Empire Connector project) were placed into service on December 10, 2008. As
of that date, Empire became an interstate pipeline subject to FERC regulation, performing services under a
FERC-approved tariff and at FERC-approved rates. The December 21, 2006 FERC order issuing Empire its
Certificate of Public Convenience and Necessity requires Empire to file a cost and revenue study at the FERC,
within three years after the in-service date, in conjunction with which Empire will either justify Empire’s
existing recourse rates or propose alternative rates.

ENVIRONMENTAL MATTERS

The Company is subject to various federal, state and local laws and regulations relating to the protection of
the environment. The Company has established procedures for the ongoing evaluation of its operations to
identify potential environmental exposures and comply with regulatory policies and procedures. It is the
Company’s policy to accrue estimated environmental clean-up costs (investigation and remediation) when such
amounts can reasonably be estimated and it is probable that the Company will be required to incur such costs. At
September 30, 2009, the Company has estimated its remaining clean-up costs related to former manufactured
gas plant sites and third party waste disposal sites will be in the range of $18.7 million to $22.9 million. The

57

minimum estimated liability of $18.7 million has been recorded on the Consolidated Balance Sheet at
September 30, 2009. The Company expects to recover its environmental clean-up costs from a combination
of rate recovery and deferred insurance proceeds that are currently recorded as a regulatory liability on the
Consolidated Balance Sheet. Other than discussed in Note I (referred to below), the Company is currently not
aware of any material additional exposure to environmental liabilities. However, changes in environmental
regulations, new information or other factors could adversely impact the Company.

For further discussion refer to Item 8 at Note I — Commitments and Contingencies under the heading

“Environmental Matters.”

Legislative and regulatory measures to address climate change and greenhouse gas emissions are in various
phases of discussions. If enacted or adopted, legislation or regulation that restricts carbon emissions could
increase the Company’s cost of environmental compliance by requiring the Company to install new equipment
to reduce emissions from larger facilities and/or purchase emission allowances. Proposed measures could also
delay or otherwise negatively affect efforts to obtain permits and other regulatory approvals with regard to
existing and new facilities. But legislation or regulation that sets a price on or otherwise restricts carbon
emissions could also benefit the Company by increasing demand for natural gas, because substantially fewer
carbon emissions per Btu of heat generated are associated with the use of natural gas than with certain alternate
fuels such as coal and oil. The effect (material or not) on the Company of any new legislative or regulatory
measures will depend on the particular provisions that are ultimately adopted.

NEW AUTHORITATIVE ACCOUNTING AND FINANCIAL REPORTING GUIDANCE

In September 2006, the FASB issued authoritative guidance for using fair value to measure assets and
liabilities. This guidance serves to clarify the extent to which companies measure assets and liabilities at fair
value, the information used to measure fair value, and the effect that fair-value measurements have on earnings.
This guidance is to be applied whenever assets or liabilities are to be measured at fair value. On October 1, 2008,
the Company adopted this guidance for financial assets and financial liabilities that are recognized or disclosed
at fair value on a recurring basis. This guidance delays the effective date for nonfinancial assets and nonfinancial
liabilities, except for items that are recognized or disclosed at fair value on a recurring basis, until the Company’s
first quarter of fiscal 2010. For further discussion of the impact of the adoption of the authoritative guidance for
financial assets and financial liabilities, refer to Item 8 at Note F — Fair Value Measurements. The Company is
currently evaluating the impact that the adoption of the authoritative guidance for nonfinancial assets and
nonfinancial liabilities will have on its consolidated financial statements. The Company has identified Goodwill
as being the major nonfinancial asset that may be impacted by the adoption of this guidance. The Company does
not believe there are any nonfinancial liabilities that will be impacted by the adoption of this guidance.

In September 2006, the FASB issued authoritative guidance which requires that companies recognize a net
liability or asset to report the underfunded or overfunded status of their defined benefit pension and other post-
retirement benefit plans on their balance sheets, as well as recognize changes in the funded status of a defined
benefit post-retirement plan in the year in which the changes occur through comprehensive income. This
guidance requires that companies recognize a net liability or asset to report the underfunded or overfunded
status of their defined benefit pension and other post-retirement benefit plans on their balance sheets, as well as
recognize changes in the funded status of a defined benefit post-retirement plan in the year in which the changes
occur through comprehensive income. This guidance also specifies that a plan’s assets and obligations that
determine its funded status be measured as of the end of the Company’s fiscal year, with limited exceptions. In
accordance with this authoritative guidance, the Company has recognized the funded status of its benefit plans
and implemented the related disclosure requirements at September 30, 2007. The requirement to measure the
plan assets and benefit obligations as of the Company’s fiscal year-end date was fully adopted by the Company as
of September 30, 2009. The Company has historically measured its plan assets and benefit obligations using a
June 30th measurement date. As a result of the change to a September 30th measurement date, the Company
recorded fifteen months of pension and other post-retirement benefit costs during fiscal 2009. Such costs were
calculated using June 30, 2008 measurement date data. Three of those months pertain to the period of July 1,
2008 to September 30, 2008. The pension and other post-retirement benefit costs for that period amounted to

58

$5.1 million and were recorded by the Company during the quarter ended December 31, 2008 as a $3.8 million
increase to Other Regulatory Assets in the Company’s Utility and Pipeline and Storage segments and a
$1.3 million ($0.8 million after tax) adjustment to earnings reinvested in the business. Refer to Item 8 at
Note H — Retirement Plan and Other Post-Retirement Benefits for further disclosures regarding the impact of
this authoritative guidance on the Company’s consolidated financial statements.

In December 2007, the FASB revised authoritative guidance that significantly changes the accounting for
business combinations in a number of areas including the treatment of contingent consideration, contingencies,
acquisition costs, in process research and development and restructuring costs. In addition, under this
guidance, changes in deferred tax asset valuation allowances and acquired income tax uncertainties in a
business combination after the measurement period will impact income tax expense. This guidance is effective
as of the Company’s first quarter of fiscal 2010.

In December 2007, the FASB issued authoritative guidance that changes the accounting and reporting for
minority interests, which will be recharacterized as noncontrolling interests (NCI) and classified as a com-
ponent of equity. This new consolidation method will significantly change the accounting for transactions with
minority interest holders. This authoritative guidance is effective as of the Company’s first quarter of fiscal 2010.
The Company currently does not have any NCI.

In March 2008, the FASB issued authoritative guidance that requires entities to provide enhanced
disclosures related to an entity’s derivative instruments and hedging activities in order to enable investors
to better understand how derivative instruments and hedging activities impact an entity’s financial reporting.
The additional disclosures include how and why an entity uses derivative instruments, how derivative
instruments and related hedged items are accounted for under authoritative guidance for derivative instruments
and hedging activities, and how derivative instruments and related hedged items affect an entity’s financial
position, financial performance, and cash flows. The Company adopted the disclosure provisions of this
authoritative guidance during the Company’s second quarter of fiscal 2009. Refer to Item 8 at Note G —
Financial Instruments for these disclosures.

In June 2008, the FASB issued authoritative guidance concerning whether certain instruments granted in
share-based payment transactions are participating securities. This guidance specified that unvested share-
based payment awards that contain nonforfeitable rights to dividends are participating securities and shall be
included in the computation of earnings per share pursuant to the “two-class” method. The “two-class” method
allocates undistributed earnings between common shares and participating securities. This authoritative
guidance is effective as of the Company’s first quarter of fiscal 2010. The Company does not believe this
guidance will have a material impact on its earnings per share calculation.

On December 31, 2008, the SEC issued a final rule on Modernization of Oil and Gas Reporting. The final
rule modifies the SEC’s reporting and disclosure rules for oil and gas reserves and aligns the full cost accounting
rules with the revised disclosures. The most notable changes of the final rule include the replacement of the
single day period-end pricing to value oil and gas reserves to a 12-month average of the first day of the month
price for each month within the reporting period. The final rule also permits voluntary disclosure of probable
and possible reserves, a disclosure previously prohibited by SEC rules. The revised reporting and disclosure
requirements are effective for the Company’s Form 10-K for the period ended September 30, 2010. Early
adoption is not permitted. The Company is currently evaluating the impact that adoption of these rules will have
on its consolidated financial statements and MD&A disclosures.

In March 2009, the FASB issued authoritative guidance that expands the disclosures required in an
employer’s financial statements about pension and other post-retirement benefit plan assets. The additional
disclosures include more details on how investment allocation decisions are made, the plan’s investment
policies and strategies, the major categories of plan assets, the inputs and valuation techniques used to measure
the fair value of plan assets, the effect of fair value measurements using significant unobservable inputs on
changes in plan assets for the period, and disclosure regarding significant concentrations of risk within plan
assets. The additional disclosure requirements are required for the Company’s Form 10-K for the period ended

59

September 30, 2010. The Company is currently evaluating the impact that adoption of this authoritative
guidance will have on its consolidated financial statement disclosures.

Effective with the June 30, 2009 Form 10-Q, the Company adopted the FASB authoritative guidance for
subsequent events that establishes general standards of accounting for and disclosure of events that occur after
the balance sheet date but before financial statements are issued or are available to be issued. Refer to Item 8 at
Note R — Subsequent Events for disclosures made as a result of the adoption of this guidance.

In June 2009, the FASB issued authoritative guidance that establishes the FASB Accounting Standards
CodificationTM (the Codification) as the source of authoritative GAAP recognized by the FASB to be applied by
all nongovernmental entities in the preparation of financial statements in conformity with GAAP. Rules and
interpretive releases of the SEC under authority of federal securities law are also sources of authoritative GAAP
for SEC registrants. All other nongrandfathered, non-SEC accounting literature not included in the Codification
will become nonauthoritative. The Codification was effective for interim and annual periods ending after
September 15, 2009. Effective with this September 30, 2009 Form 10-K, the Company has updated its
disclosures to conform to the Codification. There has been no impact on the Company’s consolidated financial
statements as the Codification does not change or alter existing GAAP.

EFFECTS OF INFLATION

Although the rate of inflation has been relatively low over the past few years, the Company’s operations
remain sensitive to increases in the rate of inflation because of its capital spending and the regulated nature of a
significant portion of its business.

SAFE HARBOR FOR FORWARD-LOOKING STATEMENTS

The Company is including the following cautionary statement in this Form 10-K to make applicable and
take advantage of the safe harbor provisions of the Private Securities Litigation Reform Act of 1995 for any
forward-looking statements made by, or on behalf of, the Company. Forward-looking statements include
statements concerning plans, objectives, goals, projections, strategies, future events or performance, and
underlying assumptions and other statements which are other than statements of historical facts. From time to
time, the Company may publish or otherwise make available forward-looking statements of this nature. All such
subsequent forward-looking statements, whether written or oral and whether made by or on behalf of the
Company, are also expressly qualified by these cautionary statements. Certain statements contained in this
report, including, without limitation, statements regarding future prospects, plans, objectives, goals, projec-
tions, strategies, future events or performance and underlying assumptions, capital structure, anticipated capital
expenditures, completion of construction projects, projections for pension and other post-retirement benefit
obligations, impacts of the adoption of new accounting rules, and possible outcomes of litigation or regulatory
proceedings, as well as statements that are identified by the use of the words “anticipates,” “estimates,”
“expects,” “forecasts,” “intends,” “plans,” “predicts,” “projects,” “believes,” “seeks,” “will,” “may,” and similar
expressions, are “forward-looking statements” as defined in the Private Securities Litigation Reform Act of 1995
and accordingly involve risks and uncertainties which could cause actual results or outcomes to differ materially
from those expressed in the forward-looking statements. The forward-looking statements contained herein are
based on various assumptions, many of which are based, in turn, upon further assumptions. The Company’s
expectations, beliefs and projections are expressed in good faith and are believed by the Company to have a
reasonable basis, including, without limitation, management’s examination of historical operating trends, data
contained in the Company’s records and other data available from third parties, but there can be no assurance
that management’s expectations, beliefs or projections will result or be achieved or accomplished. In addition to
other factors and matters discussed elsewhere herein, the following are important factors that, in the view of the
Company, could cause actual results to differ materially from those discussed in the forward-looking statements:

1. Financial and economic conditions, including the availability of credit, and their effect on the Company’s
ability to obtain financing on acceptable terms for working capital, capital expenditures and other
investments;

60

2. Occurrences affecting the Company’s ability to obtain financing under credit lines or other credit facilities
or through the issuance of commercial paper, other short-term notes or debt or equity securities, including

conditions;

3. Changes in economic conditions, including global, national or regional recessions, and their effect on the

demand for, and customers’ ability to pay for, the Company’s products and services;

5. Economic disruptions or uninsured losses resulting from terrorist activities, acts of war, major accidents,

fires, hurricanes, other severe weather, pest infestation or other natural disasters;

6. Changes in actuarial assumptions, the interest rate environment and the return on plan/trust assets related
to the Company’s pension and other post-retirement benefits, which can affect future funding obligations
and costs and plan liabilities;

7. Changes in demographic patterns and weather conditions;

8. Changes in the availability and/or price of natural gas or oil and the effect of such changes on the
accounting treatment of derivative financial instruments or the valuation of the Company’s natural gas and
oil reserves;

9. Impairments under the SEC’s full cost ceiling test for natural gas and oil reserves;

10. Uncertainty of oil and gas reserve estimates;

11. Factors affecting the Company’s ability to successfully identify, drill for and produce economically viable
natural gas and oil reserves, including among others geology, lease availability, weather conditions,
shortages, delays or unavailability of equipment and services required in drilling operations, and the
need to obtain governmental approvals and permits and comply with environmental
laws and
regulations;

12. Significant differences between the Company’s projected and actual production levels for natural gas or

oil;

13. Changes in the availability and/or price of derivative financial instruments;

14. Changes in the price differentials between oil having different quality and/or different geographic
locations, or changes in the price differentials between natural gas having different heating values and/or
different geographic locations;

15. Inability to obtain new customers or retain existing ones;

16. Significant changes in competitive factors affecting the Company;

17. Changes in laws and regulations to which the Company is subject, including tax, environmental, safety

and employment laws and regulations;

18. Governmental/regulatory actions, initiatives and proceedings, including those involving acquisitions,
financings, rate cases (which address, among other things, allowed rates of return, rate design and
retained natural gas), affiliate relationships, industry structure, franchise renewal, and environmental/
safety requirements;

19. Unanticipated impacts of restructuring initiatives in the natural gas and electric industries;

20. Significant differences between the Company’s projected and actual capital expenditures and operating

expenses, and unanticipated project delays or changes in project costs or plans;

61

21. The nature and projected profitability of pending and potential projects and other investments, and the

ability to obtain necessary governmental approvals and permits;

22. Ability to successfully identify and finance acquisitions or other investments and ability to operate and

integrate existing and any subsequently acquired business or properties;

23. Significant changes in tax rates or policies or in rates of inflation or interest;

24. Significant changes in the Company’s relationship with its employees or contractors and the potential

adverse effects if labor disputes, grievances or shortages were to occur;

25. Changes in accounting principles or the application of such principles to the Company;

26. The cost and effects of legal and administrative claims against the Company or activist shareholder

campaigns to effect changes at the Company;

27. Increasing health care costs and the resulting effect on health insurance premiums and on the obligation

to provide other post-retirement benefits; or

28. Increasing costs of insurance, changes in coverage and the ability to obtain insurance.

The Company disclaims any obligation to update any forward-looking statements to reflect events or

circumstances after the date hereof.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Shareholders of National Fuel Gas Company:

In our opinion, the consolidated financial statements listed in the accompanying index present fairly, in all
material respects, the financial position of National Fuel Gas Company and its subsidiaries at September 30,
2009 and 2008, and the results of their operations and their cash flows for each of the three years in the period
ended September 30, 2009 in conformity with accounting principles generally accepted in the United States of
America. In addition, in our opinion, the financial statement schedule listed in the accompanying index presents
fairly, in all material respects, the information set forth therein when read in conjunction with the related
consolidated financial statements. Also in our opinion, the Company maintained, in all material respects,
effective internal control over financial reporting as of September 30, 2009, based on criteria established in
Internal Control — Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway
Commission (COSO). The Company’s management is responsible for these financial statements and financial
statement schedule, for maintaining effective internal control over financial reporting and for its assessment of
the effectiveness of internal control over financial reporting, included in Management’s Report on Internal
Control over Financial Reporting appearing under Item 9A. Our responsibility is to express opinions on these
financial statements, on the financial statement schedule, and on the Company’s internal control over financial
reporting based on our integrated audits. We conducted our audits in accordance with the standards of the
Public Company Accounting Oversight Board (United States). Those standards require that we plan and
perform the audits to obtain reasonable assurance about whether the financial statements are free of material
misstatement and whether effective internal control over financial reporting was maintained in all material
respects. Our audits of the financial statements included examining, on a test basis, evidence supporting the
amounts and disclosures in the financial statements, assessing the accounting principles used and significant
estimates made by management, and evaluating the overall financial statement presentation. Our audit of
internal control over financial reporting included obtaining an understanding of internal control over financial
reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating
effectiveness of internal control based on the assessed risk. Our audits also included performing such other
procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable
basis for our opinions.

A company’s internal control over financial reporting is a process designed to provide reasonable assurance
regarding the reliability of financial reporting and the preparation of financial statements for external purposes
in accordance with generally accepted accounting principles. A company’s internal control over financial
reporting includes those policies and procedures that (i) pertain to the maintenance of records that, in
reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company;
(ii) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial
statements in accordance with generally accepted accounting principles, and that receipts and expenditures of
the company are being made only in accordance with authorizations of management and directors of the
company; and (iii) provide reasonable assurance regarding prevention or timely detection of unauthorized
acquisition, use, or disposition of the company’s assets that could have a material effect on the financial
statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that
controls may become inadequate because of changes in conditions, or that the degree of compliance with the
policies or procedures may deteriorate.

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

Note A — Summary of Significant Accounting Policies

Principles of Consolidation

The Company consolidates its majority owned entities. The equity method is used to account for minority
owned entities. All significant intercompany balances and transactions are eliminated. The Company uses
proportionate consolidation when accounting for drilling arrangements related to oil and gas producing
properties accounted for under the full cost method of accounting.

The preparation of the consolidated financial statements in conformity with GAAP requires management to
make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of
contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and
expenses during the reporting period. Actual results could differ from those estimates.

Regulation

The Company is subject to regulation by certain state and federal authorities. The Company has accounting
policies which conform to GAAP, as applied to regulated enterprises, and are in accordance with the accounting
requirements and ratemaking practices of the regulatory authorities. Reference is made to Note C — Regulatory
Matters for further discussion.

Revenue Recognition

The Company’s Utility segment records revenue as bills are rendered, except that service supplied but not
billed is reported as unbilled utility revenue and is included in operating revenues for the year in which service is
furnished.

The Company’s Energy Marketing segment records revenue as bills are rendered for service supplied on a

calendar month basis.

The Company’s Pipeline and Storage segment records revenue for natural gas transportation and storage
services. Revenue from reservation charges on firm contracted capacity is recognized through equal monthly
charges over the contract period regardless of the amount of gas that is transported or stored. Commodity
charges on firm contracted capacity and interruptible contracts are recognized as revenue when physical
deliveries of natural gas are made at the agreed upon delivery point or when gas is injected or withdrawn from
the storage field. The point of delivery into the pipeline or injection or withdrawal from storage is the point at
which ownership and risk of loss transfers to the buyer of such transportation and storage services.

The Company’s Exploration and Production segment records revenue based on entitlement, which means
that revenue is recorded based on the actual amount of gas or oil that is delivered to a pipeline and the
Company’s ownership interest in the producing well. If a production imbalance occurs between what was
supposed to be delivered to a pipeline and what was actually produced and delivered, the Company accrues the
difference as an imbalance.

Allowance for Uncollectible Accounts

The allowance for uncollectible accounts is the Company’s best estimate of the amount of probable credit
losses in the existing accounts receivable. The allowance is determined based on historical experience, the age
and other specific information about customer accounts. Account balances are charged off against the allowance
twelve months after the account is final billed or when it is anticipated that the receivable will not be recovered.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Regulatory Mechanisms

The Company’s rate schedules in the Utility segment contain clauses that permit adjustment of revenues to
reflect price changes from the cost of purchased gas included in base rates. Differences between amounts
currently recoverable and actual adjustment clause revenues, as well as other price changes and pipeline and
storage company refunds not yet includable in adjustment clause rates, are deferred and accounted for as either
unrecovered purchased gas costs or amounts payable to customers. Such amounts are generally recovered from
(or passed back to) customers during the following fiscal year.

Estimated refund liabilities to ratepayers represent management’s current estimate of such refunds.

Reference is made to Note C — Regulatory Matters for further discussion.

The impact of weather on revenues in the Utility segment’s New York rate jurisdiction is tempered by a
WNC, which covers the eight-month period from October through May. The WNC is designed to adjust the
rates of retail customers to reflect the impact of deviations from normal weather. Weather that is warmer than
normal results in a surcharge being added to customers’ current bills, while weather that is colder than normal
results in a refund being credited to customers’ current bills. Since the Utility segment’s Pennsylvania rate
jurisdiction does not have a WNC, weather variations have a direct impact on the Pennsylvania rate
jurisdiction’s revenues.

The impact of weather normalized usage per customer account in the Utility segment’s New York rate
jurisdiction is tempered by a revenue decoupling mechanism. The effect of the revenue decoupling mechanism
is to render the Company financially indifferent to throughput decreases resulting from conservation. Weather
normalized usage per account that exceeds the average weather normalized usage per customer account results
in a refund being credited to customers’ bills. Weather normalized usage per account that is below the average
weather normalized usage per account results in a surcharge being added to customers’ bills. The surcharge or
credit is calculated over a twelve-month period ending December 31st, and applied to customer bills annually,
beginning March 1st.

In the Pipeline and Storage segment, the allowed rates that Supply Corporation bills its customers are based
on a straight fixed-variable rate design, which allows recovery of all fixed costs, including return on equity and
income taxes, through fixed monthly reservation charges. Because of this rate design, changes in throughput
due to weather variations do not have a significant impact on the revenues of Supply Corporation.

Prior to December 10, 2008, the allowed rates that Empire billed its customers were based on a modified
fixed-variable rate design, which recovered return on equity and income taxes through variable charges.
Because of this rate design, changes in throughput due to weather variations could have had a significant impact
on Empire’s revenues. On December 10, 2008, Empire became FERC regulated. As a result, Empire now bills its
customers based on a straight fixed-variable rate design. Changes in throughput due to weather variations no
longer have a significant impact on Empire’s revenue.

Property, Plant and Equipment

The principal assets of the Utility and Pipeline and Storage segments, consisting primarily of gas plant in
service, are recorded at the historical cost when originally devoted to service in the regulated businesses, as
required by regulatory authorities.

In the Company’s Exploration and Production segment, oil and gas property acquisition, exploration and
development costs are capitalized under the full cost method of accounting. Under this methodology, all costs
associated with property acquisition, exploration and development activities are capitalized, including internal
costs directly identified with acquisition, exploration and development activities. The internal costs that are
capitalized do not include any costs related to production, general corporate overhead, or similar activities. The
Company does not recognize any gain or loss on the sale or other disposition of oil and gas properties unless the

70

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

gain or loss would significantly alter the relationship between capitalized costs and proved reserves of oil and
gas attributable to a cost center.

Capitalized costs include costs related to unproved properties, which are excluded from amortization until
proved reserves are found or it is determined that the unproved properties are impaired. All costs related to
unproved properties are reviewed quarterly to determine if impairment has occurred. The amount of any
impairment is transferred to the pool of capitalized costs being amortized.

Capitalized costs are subject to the SEC full cost ceiling test. The ceiling test, which is performed each
quarter, determines a limit, or ceiling, on the amount of property acquisition, exploration and development costs
that can be capitalized. The ceiling under this test represents (a) the present value of estimated future net cash
flows, excluding future cash outflows associated with settling asset retirement obligations that have been accrued
on the balance sheet, using a discount factor of 10%, which is computed by applying current market prices of oil
and gas (as adjusted for hedging) to estimated future production of proved oil and gas reserves as of the date of the
latest balance sheet, less estimated future expenditures, plus (b) the cost of unevaluated properties not being
depleted, less (c) income tax effects related to the differences between the book and tax basis of the properties. If
capitalized costs, net of accumulated depreciation, depletion and amortization and related deferred income taxes,
exceed the ceiling at the end of any quarter, a permanent impairment is required to be charged to earnings in that
quarter. In adjusting estimated future net cash flows for hedging under the ceiling test at September 30, 2009,
2008, and 2007, estimated future net cash flows were increased by $143.3 million, $34.5 million and $2.2 million,
respectively. The Company’s capitalized costs exceeded the full cost ceiling for the Company’s oil and gas
properties at December 31, 2008. As such, the Company recognized a pre-tax impairment of $182.8 million at
December 31, 2008. Deferred income taxes of $74.6 million were recorded associated with this impairment.

Maintenance and repairs of property and replacements of minor items of property are charged directly to
maintenance expense. The original cost of the regulated subsidiaries’ property, plant and equipment retired, and
the cost of removal less salvage, are charged to accumulated depreciation.

Depreciation, Depletion and Amortization

For oil and gas properties, depreciation, depletion and amortization is computed based on quantities
produced in relation to proved reserves using the units of production method. The cost of unproved oil and gas
properties is excluded from this computation. In the All Other category, for timber properties, depletion,
determined on a property by property basis, is charged to operations based on the actual amount of timber cut in
relation to the total amount of recoverable timber. For all other property, plant and equipment, depreciation,
depletion and amortization is computed using the straight-line method in amounts sufficient to recover costs
over the estimated service lives of property in service. The following is a summary of depreciable plant by
segment:

and 2007, respectively. Depletion of oil and gas producing properties in the United States amounted to
$2.10, $2.23 and $1.97 per Mcfe of production in 2009, 2008 and 2007, respectively. Depletion of oil and
gas producing properties in Canada amounted to $1.67 per Mcfe of production in 2007.

Goodwill

The Company has recognized goodwill of $5.5 million as of September 30, 2009 and 2008 on its
Consolidated Balance Sheets related to the Company’s acquisition of Empire in 2003. The Company accounts
for goodwill in accordance with the current authoritative guidance, which requires the Company to test
goodwill for impairment annually. At September 30, 2009 and 2008, the fair value of Empire was greater than its
book value. As such, the goodwill was considered not impaired.

Financial Instruments

Unrealized gains or losses from the Company’s investments in an equity mutual fund and the stock of an
insurance company (securities available for sale) are recorded as a component of accumulated other compre-
hensive income (loss). Reference is made to Note G — Financial Instruments for further discussion.

The Company uses a variety of derivative financial instruments to manage a portion of the market risk
associated with fluctuations in the price of natural gas and crude oil. These instruments include price swap
agreements and futures contracts. The Company accounts for these instruments as either cash flow hedges or
fair value hedges. In both cases, the fair value of the instrument is recognized on the Consolidated Balance
Sheets as either an asset or a liability labeled fair value of derivative financial instruments. Reference is made to
Note F — Fair Value Measurements for further discussion concerning the fair value of derivative financial
instruments.

For effective cash flow hedges, the offset to the asset or liability that is recorded is a gain or loss recorded in
accumulated other comprehensive income (loss) on the Consolidated Balance Sheets. The gain or loss recorded
in accumulated other comprehensive income (loss) remains there until the hedged transaction occurs, at which
point the gains or losses are reclassified to operating revenues, purchased gas expense or interest expense on the
Consolidated Statements of Income. Any ineffectiveness associated with the cash flow hedges is recorded in the
Consolidated Statements of Income. In December 2006, the Company repaid $22.8 million of Empire’s secured
debt. The interest costs of this secured debt were hedged by an interest rate collar. Since the hedged transaction
was settled and there will be no future cash flows associated with the secured debt, hedge accounting for the
interest rate collar was discontinued and the unrealized gain of $1.9 million in accumulated other compre-
hensive income associated with the interest rate collar was reclassified to the Consolidated Statement of Income.
The Company did not experience any material ineffectiveness with regard to its cash flow hedges during 2009 or
2008.

72

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

For fair value hedges, the offset to the asset or liability that is recorded is a gain or loss recorded to operating
revenues or purchased gas expense on the Consolidated Statements of Income. However, in the case of fair value
hedges, the Company also records an asset or liability on the Consolidated Balance Sheets representing the
change in fair value of the asset or firm commitment that is being hedged (see Other Current Assets section in
this footnote). The offset to this asset or liability is a gain or loss recorded to operating revenues or purchased gas
expense on the Consolidated Statements of Income as well. If the fair value hedge is effective, the gain or loss
from the derivative financial instrument is offset by the gain or loss that arises from the change in fair value of the
asset or firm commitment that is being hedged. The Company did not experience any material ineffectiveness
with regard to its fair value hedges during 2009, 2008 or 2007.

At September 30, 2009, it is estimated that of the $18.5 million net unrealized gain on derivative financial
instruments shown in the table above, $18.6 million of unrealized gains will be reclassified into the Consol-
idated Statement of Income during 2010. The remaining unrealized loss on derivative financial instruments of
$0.1 million will be reclassified into the Consolidated Statement of Income in subsequent years. The Company’s
derivative financial instruments extend out to 2012.

The amounts included in accumulated other comprehensive income (loss) related to the funded status of
the Company’s pension and other post-retirement benefit plans consist of prior service costs and accumulated
losses. The total amount for prior service costs was $0.3 million and $0.4 million at September 30, 2009 and
September 30, 2008, respectively. The total amount for accumulated losses was $63.5 million and $19.3 million
at September 30, 2009 and September 30, 2008, respectively.

Gas Stored Underground — Current

In the Utility segment, gas stored underground — current in the amount of $30.4 million is carried at lower
of cost or market, on a LIFO method. Based upon the average price of spot market gas purchased in September
2009, including transportation costs, the current cost of replacing this inventory of gas stored underground —
current exceeded the amount stated on a LIFO basis by approximately $51.6 million at September 30, 2009. All
other gas stored underground — current, which is in the Energy Marketing segment, is carried at lower of cost
or market on an average cost method.

Purchased Timber Rights

The Company purchases the right to harvest timber from land owned by other parties. These rights, which
extend from several months to several years, are purchased to ensure an adequate supply of timber for the
Company’s sawmill and kiln operations. The historical value of timber rights expected to be harvested during
the following year are included in Materials and Supplies on the Consolidated Balance Sheets while the

Unamortized Debt Expense

Costs associated with the issuance of debt by the Company are deferred and amortized over the lives of the
related debt. Costs associated with the reacquisition of debt related to rate-regulated subsidiaries are deferred
and amortized over the remaining life of the issue or the life of the replacement debt in order to match regulatory
treatment.

Foreign Currency Translation

The functional currency for the Company’s foreign operations is the local currency of the country where the
operations are located. Asset and liability accounts are translated at the rate of exchange on the balance sheet
date. Revenues and expenses are translated at the average exchange rate during the period. Foreign currency
translation adjustments are recorded as a component of accumulated other comprehensive income (loss). With
the sale of SECI on August 31, 2007, the Company eliminated its major foreign operation. While the Company is
in the process of winding up or selling certain power development projects in Europe, the investment in such
projects is not significant and the Company does not expect to have any significant foreign currency translation
adjustments in the future.

Income Taxes

The Company and its domestic subsidiaries file a consolidated federal income tax return. Investment tax
credit, prior to its repeal in 1986, was deferred and is being amortized over the estimated useful lives of the
related property, as required by regulatory authorities having jurisdiction.

Consolidated Statements of Cash Flows

For purposes of the Consolidated Statements of Cash Flows, the Company considers all highly liquid debt

instruments purchased with a maturity of three months or less to be cash equivalents.

At September 30, 2009, the Company accrued $9.1 million of capital expenditures in the Exploration and
Production segment, the majority of which was in the Appalachian region. The Company also accrued
$0.7 million of capital expenditures in the All Other category related to the construction of the Midstream
Covington Gathering System at September 30, 2009. These amounts were excluded from the Consolidated
Statement of Cash Flows at September 30, 2009 since they represent non-cash investing activities at that date.

At September 30, 2008, the Company accrued $16.8 million of capital expenditures related to the
construction of the Empire Connector project. This amount was excluded from the Consolidated Statement
of Cash Flows at September 30, 2008 since it represented a non-cash investing activity at that date. These capital
expenditures were paid during the quarter ended December 31, 2008 and have been included in the
Consolidated Statement of Cash Flows for the year ended September 30, 2009.

Hedging Collateral Account

This is an account title for cash held in margin accounts funded by the Company to serve as collateral for
open hedging positions. At September 30, 2009, the Company had hedging collateral deposits of $0.8 million
related to its exchange-traded futures contracts. It is the Company’s policy to not offset hedging collateral
deposits paid or received against the derivative financial instruments liability or asset balances.

Cash Held in Escrow

On July 20, 2009, the Company’s wholly-owned subsidiary in the Exploration and Production segment,
Seneca, acquired Ivanhoe Energy’s United States oil and gas operations for approximately $39.2 million in cash
(including cash acquired of $4.3 million). The cash acquired at acquisition includes $2 million held in escrow at
September 30, 2009. Seneca placed this amount in escrow as part of the purchase price, and in accordance with
the purchase agreement, this amount will remain in escrow for one year from the closing of the transaction
provided there are no pending disputes or actions regarding obligations and liabilities required to be satisfied or
discharged by Ivanhoe Energy.

On August 31, 2007, the Company received approximately $232.1 million of proceeds from the sale of
SECI, of which $58.0 million was placed in escrow pending receipt of a tax clearance certificate from the
Canadian government. The escrow account was a Canadian dollar denominated account. On a U.S. dollar basis,
the value of this account was $62.0 million at September 30, 2007. In December 2007, the Canadian government
issued the tax clearance certificate, thereby releasing the proceeds from restriction as of December 31, 2007. To
hedge against foreign currency exchange risk related to the cash being held in escrow, the Company held a
forward contract to sell Canadian dollars. For presentation purposes on the Consolidated Statement of Cash
Flows, for the year ended September 30, 2008, the Cash Held in Escrow line item within Investing Activities
reflects the net proceeds to the Company (received on January 8, 2008) after adjusting for the impact of the
foreign currency hedge.

Other Current Assets

Other Current Assets consist of prepayments in the amounts of $12.2 million and $10.6 million at
September 30, 2009 and 2008, respectively, prepaid property and other taxes of $12.0 million and $11.2 million
at September 30, 2009 and 2008, respectively, federal income taxes receivable in the amounts of $23.3 million
and $27.5 million at September 30, 2009 and 2008, respectively, state income taxes receivable in the amounts of
$13.5 million and $5.0 million at September 30, 2009 and 2008, respectively, and fair values of firm
commitments in the amounts of $7.5 million and $10.9 million at September 30, 2009 and 2008, respectively.

Customer Advances

The Company’s Utility and Energy Marketing segments have balanced billing programs whereby customers
pay their estimated annual usage in equal installments over a twelve-month period. Monthly payments under
the balanced billing programs are typically higher than current month usage during the summer months.
During the winter months, monthly payments under the balanced billing programs are typically lower than
current month usage. At September 30, 2009 and 2008, customers in the balanced billing programs had
advanced excess funds of $24.6 million and $33.0 million, respectively.

Customer Security Deposits

The Company, in its Utility, Pipeline and Storage, and Energy Marketing segments, often times requires
security deposits from marketers, producers, pipeline companies, and commercial and industrial customers
before providing services to such customers. At September 30, 2009 and 2008, the Company had received
customer security deposits amounting to $17.4 million and $14.0 million, respectively.

Earnings Per Common Share

Basic earnings per common share is computed by dividing income available for common stock by the
weighted average number of common shares outstanding for the period. Diluted earnings per common share
reflects the potential dilution that could occur if securities or other contracts to issue common stock were
exercised or converted into common stock. For purposes of determining earnings per common share, the only
potentially dilutive securities the Company has outstanding are stock options and stock-settled SARs. The
diluted weighted average shares outstanding shown on the Consolidated Statements of Income reflects the
potential dilution as a result of these stock options and stock-settled SARs as determined using the Treasury
Stock Method. Stock options and stock-settled SARs that are antidilutive are excluded from the calculation of
diluted earnings per common share. For 2009, there were 365,000 stock-settled SARs and 765,000 stock options
excluded as being antidilutive. For 2008, there were 7,344 stock-settled SARs excluded as being antidilutive,
and there were no stock options excluded as being antidilutive. For 2007, no stock options or stock-settled SARs
were excluded as being antidilutive.

Share Repurchases

The Company considers all shares repurchased as cancelled shares restored to the status of authorized but
unissued shares, in accordance with New Jersey law. The repurchases are accounted for on the date the share
repurchase is settled as an adjustment to common stock (at par value) with the excess repurchase price allocated
between paid in capital and retained earnings. Refer to Note E — Capitalization and Short-Term Borrowings for
further discussion of the share repurchase program.

Stock-Based Compensation

The Company has various stock option and stock award plans which provide or provided for the issuance
of one or more of the following to key employees: incentive stock options, nonqualified stock options, stock-
settled SARs, restricted stock, performance units or performance shares. Stock options and stock-settled SARs
under all plans have exercise prices equal to the average market price of Company common stock on the date of
grant, and generally no stock option or stock-settled SAR is exercisable less than one year or more than ten years
after the date of each grant. Restricted stock is subject to restrictions on vesting and transferability. Restricted
stock awards entitle the participants to full dividend and voting rights. Certificates for shares of restricted stock
awarded under the Company’s stock option and stock award plans are held by the Company during the periods
in which the restrictions on vesting are effective. Restrictions on restricted stock awards generally lapse ratably
over a period of not more than ten years after the date of each grant.

The Company follows authoritative guidance which requires the measurement and recognition of com-
pensation cost at fair value for all share-based payments, including stock options and stock-settled SARs. The
Company has chosen the Black-Scholes-Merton closed form model to calculate the compensation expense
associated with such share-based payments since it is easier to administer than the Binomial option-pricing
model. Furthermore, since the Company does not have complex stock-based compensation awards, it does not
believe that compensation expense would be materially different under either model.

The Company did not grant any stock options during the years ended September 30, 2009 and 2008. There
were 448,000 stock options granted during the year ended September 30, 2007. The Company granted 610,000
and 321,000 performance based stock-settled SARs during the year ended September 30, 2009 and 2008,
respectively, but did not grant any performance based stock-settled SARs during the year ended September 30,
2007. The Company granted 50,000 non-performance based stock-settled SARs during the year ended
September 30, 2007, but did not grant any non-performance based stock-settled SARs during the years ended
September 30, 2009 and 2008. The accounting treatment for such performance based and non-performance
based stock-settled SARs is the same as the accounting for stock options under the current authoritative
guidance for stock-based compensation. The performance based stock-settled SARs granted for the year ended

76

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

September 30, 2009 vest and become exercisable annually in one-third increments, provided that a performance
condition is met. The performance condition for each fiscal year, generally stated, is an increase over the prior
fiscal year of at least five percent in certain oil and natural gas production of the Exploration and Production
segment. The performance based stock-settled SARs granted for the year ended September 30, 2008 vest and
become exercisable annually, in one-third increments, provided that a performance condition for diluted
earnings per share is met for the prior fiscal year. The weighted average grant date fair value of the performance
based stock-settled SARs granted during 2009 and 2008 was estimated on the date of grant using the same
accounting treatment that is applied for stock options, and assumes that the performance conditions specified
will be achieved. If such conditions are not met or it is not considered probable that such conditions will be met,
no compensation expense is recognized and any previously recognized compensation expense is reversed.
During 2009, the Company reversed $0.5 million of previously recognized compensation expense associated
with performance based stock-settled SARs. The Company also granted 63,000, 25,000, and 25,000 restricted
share awards (non-vested stock as defined by the current accounting literature) during the years ended
September 30, 2009, 2008 and 2007, respectively.

Stock-based compensation expense for the years ended September 30, 2009, 2008 and 2007 was
approximately $2.1 million (net of the $0.5 million reversal of compensation expense discussed above),
$2.3 million, and $3.7 million, respectively. Stock-based compensation expense is included in operation and
maintenance expense on the Consolidated Statement of Income. The total income tax benefit related to stock-
based compensation expense during the years ended September 30, 2009, 2008 and 2007 was approximately
$0.8 million, $0.9 million and $1.5 million, respectively. There were no capitalized stock-based compensation
costs during the years ended September 30, 2009 and 2008.

Stock Options

The total intrinsic value of stock options exercised during the years ended September 30, 2009, 2008 and
2007 totaled approximately $18.7 million, $24.6 million, and $38.7 million, respectively. For 2009, 2008 and
2007, the amount of cash received by the Company from the exercise of such stock options was approximately
$29.2 million, $18.5 million, and $26.0 million, respectively.

The Company realizes tax benefits related to the exercise of stock options on a calendar year basis as
opposed to a fiscal year basis. As such, for stock options exercised during the quarters ended December 31,
2008, 2007, and 2006, the Company realized a tax benefit of $1.6 million, $4.4 million, and $3.2 million,
respectively. For stock options exercised during the period of January 1, 2009 through September 30, 2009, the
Company will realize a tax benefit of approximately $5.7 million in the quarter ended December 31, 2009. For
stock options exercised during the period of January 1, 2008 through September 30, 2008, the Company
realized a tax benefit of approximately $4.3 million in the quarter ended December 31, 2008. For stock options
exercised during the period of January 1, 2007 through September 30, 2007, the Company realized a tax benefit
of approximately $12.0 million in the quarter ended December 31, 2007. The weighted average grant date fair
value of options granted in 2007 is $7.27 per share. As stated above, there were no stock options granted during
the years ended September 30, 2009 and 2008. For the years ended September 30, 2009, 2008 and 2007, 27,000,
358,000 and 327,501 stock options became fully vested, respectively. The total fair value of the stock options
that became vested during the years ended September 30, 2009, 2008 and 2007 was approximately $0.2 million,
$2.6 million and $2.1 million, respectively. As of September 30, 2009, unrecognized compensation expense
related to stock options totaled approximately $47,000, which will be recognized over a weighted average
period of 3.0 months. For a summary of transactions during 2009 involving option shares for all plans, refer to
Note E — Capitalization and Short-Term Borrowings.

Non-Performance Based Stock-settled SARs

Participants in the stock option and award plans did not exercise any non-performance based stock-settled
SARs during the years ended September 30, 2009, 2008 and 2007 since none of the non-performance based
stock-settled SARs granted have vested. As stated above, there were 50,000 non-performance based stock-
settled SARs granted during 2007. The weighted average grant date fair value of non-performance based stock-
settled SARs granted in 2007 is $7.81 per share. The Company did not grant any non-performance based stock-
settled SARs during 2009 or 2008. As of September 30, 2009, unrecognized compensation expense related to
non-performance based stock-settled SARs totaled approximately $0.1 million, which will be recognized over a
weighted average period of 4.3 months. For a summary of transactions during 2009 involving non-performance
based stock-settled SARs for all plans, refer to Note E — Capitalization and Short-Term Borrowings.

The fair value of non-performance based stock-settled SARs at the date of grant was estimated using the

respectively. The weighted average grant date fair value of performance based stock-settled SARs granted in
2009 and 2008 is $4.09 per share and $9.06 per share, respectively. The Company did not grant any performance
based stock-settled SARs during 2007. For the year ended September 30, 2009, 96,984 performance based
stock-settled SARs became fully vested. Fiscal 2009 was the first year in which performance based stock-settled
SARs became vested. The total fair value of the performance based stock-settled SARs that became vested during
the year ended September 30, 2009 was approximately $0.8 million. As of September 30, 2009, unrecognized
compensation expense related to performance based stock-settled SARs totaled approximately $1.3 million,
which will be recognized over a weighted average period of 10.9 months. For a summary of transactions during
2009 involving performance based stock-settled SARs for all plans, refer to Note E — Capitalization and Short-

Restricted Share Awards

The weighted average fair value of restricted share awards granted in 2009, 2008 and 2007 is $47.46 per
share, $48.41 per share and $40.18 per share, respectively. As of September 30, 2009, unrecognized compen-
sation expense related to restricted share awards totaled approximately $3.9 million, which will be recognized
over a weighted average period of 4.4 years. For a summary of transactions during 2009 involving restricted
share awards, refer to Note E — Capitalization and Short-Term Borrowings.

New Authoritative Accounting and Financial Reporting Guidance

In September 2006, the FASB issued authoritative guidance for using fair value to measure assets and
liabilities. This guidance serves to clarify the extent to which companies measure assets and liabilities at fair
value, the information used to measure fair value, and the effect that fair-value measurements have on earnings.
This guidance is to be applied whenever assets or liabilities are to be measured at fair value. On October 1, 2008,
the Company adopted this guidance for financial assets and financial liabilities that are recognized or disclosed
at fair value on a recurring basis. This guidance delays the effective date for nonfinancial assets and nonfinancial
liabilities, except for items that are recognized or disclosed at fair value on a recurring basis, until the Company’s
first quarter of fiscal 2010. For further discussion of the impact of the adoption of the authoritative guidance for
financial assets and financial liabilities, refer to Note F — Fair Value Measurements. The Company is currently
evaluating the impact that the adoption of the authoritative guidance for nonfinancial assets and nonfinancial
liabilities will have on its consolidated financial statements. The Company has identified Goodwill as being the
major nonfinancial asset that may be impacted by the adoption of this guidance. The Company does not believe
there are any nonfinancial liabilities that will be impacted by the adoption of this guidance.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

In September 2006, the FASB issued authoritative guidance which requires that companies recognize a net
liability or asset to report the underfunded or overfunded status of their defined benefit pension and other post-
retirement benefit plans on their balance sheets, as well as recognize changes in the funded status of a defined
benefit post-retirement plan in the year in which the changes occur through comprehensive income. This
guidance requires that companies recognize a net liability or asset to report the underfunded or overfunded
status of their defined benefit pension and other post-retirement benefit plans on their balance sheets, as well as
recognize changes in the funded status of a defined benefit post-retirement plan in the year in which the changes
occur through comprehensive income. This guidance also specifies that a plan’s assets and obligations that
determine its funded status be measured as of the end of the Company’s fiscal year, with limited exceptions. In
accordance with this authoritative guidance, the Company has recognized the funded status of its benefit plans
and implemented the related disclosure requirements at September 30, 2007. The requirement to measure the
plan assets and benefit obligations as of the Company’s fiscal year-end date was fully adopted by the Company as
of September 30, 2009. The Company has historically measured its plan assets and benefit obligations using a
June 30th measurement date. As a result of the change to a September 30th measurement date, the Company
recorded fifteen months of pension and other post-retirement benefit costs during fiscal 2009. Such costs were
calculated using June 30, 2008 measurement date data. Three of those months pertain to the period of July 1,
2008 to September 30, 2008. The pension and other post-retirement benefit costs for that period amounted to
$5.1 million and were recorded by the Company during the quarter ended December 31, 2008 as a $3.8 million
increase to Other Regulatory Assets in the Company’s Utility and Pipeline and Storage segments and a
$1.3 million ($0.8 million after tax) adjustment to earnings reinvested in the business. Refer to Note H —
Retirement Plan and Other Post-Retirement Benefits for further disclosures regarding the impact of this
authoritative guidance on the Company’s consolidated financial statements.

In December 2007, the FASB revised authoritative guidance that significantly changes the accounting for
business combinations in a number of areas including the treatment of contingent consideration, contingencies,
acquisition costs, in process research and development and restructuring costs. In addition, under this
guidance, changes in deferred tax asset valuation allowances and acquired income tax uncertainties in a
business combination after the measurement period will impact income tax expense. This guidance is effective
as of the Company’s first quarter of fiscal 2010.

In December 2007, the FASB issued authoritative guidance that changes the accounting and reporting for
minority interests, which will be recharacterized as noncontrolling interests (NCI) and classified as a com-
ponent of equity. This new consolidation method will significantly change the accounting for transactions with
minority interest holders. This authoritative guidance is effective as of the Company’s first quarter of fiscal 2010.
The Company currently does not have any NCI.

In March 2008, the FASB issued authoritative guidance that requires entities to provide enhanced
disclosures related to an entity’s derivative instruments and hedging activities in order to enable investors
to better understand how derivative instruments and hedging activities impact an entity’s financial reporting.
The additional disclosures include how and why an entity uses derivative instruments, how derivative
instruments and related hedged items are accounted for under authoritative guidance for derivative instruments
and hedging activities, and how derivative instruments and related hedged items affect an entity’s financial
position, financial performance, and cash flows. The Company adopted the disclosure provisions of this
authoritative guidance during the Company’s second quarter of fiscal 2009. Refer to Note G — Financial
Instruments for these disclosures.

In June 2008, the FASB issued authoritative guidance concerning whether certain instruments granted in
share-based payment transactions are participating securities. This guidance specified that unvested share-
based payment awards that contain nonforfeitable rights to dividends are participating securities and shall be
included in the computation of earnings per share pursuant to the “two-class” method. The “two-class” method
allocates undistributed earnings between common shares and participating securities. This authoritative

80

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

guidance is effective as of the Company’s first quarter of fiscal 2010. The Company does not believe this
guidance will have a material impact on its earnings per share calculation.

On December 31, 2008, the SEC issued a final rule on Modernization of Oil and Gas Reporting. The final
rule modifies the SEC’s reporting and disclosure rules for oil and gas reserves and aligns the full cost accounting
rules with the revised disclosures. The most notable changes of the final rule include the replacement of the
single day period-end pricing to value oil and gas reserves to a 12-month average of the first day of the month
price for each month within the reporting period. The final rule also permits voluntary disclosure of probable
and possible reserves, a disclosure previously prohibited by SEC rules. The revised reporting and disclosure
requirements are effective for the Company’s Form 10-K for the period ended September 30, 2010. Early
adoption is not permitted. The Company is currently evaluating the impact that adoption of these rules will have
on its consolidated financial statements and MD&A disclosures.

In March 2009, the FASB issued authoritative guidance that expands the disclosures required in an
employer’s financial statements about pension and other post-retirement benefit plan assets. The additional
disclosures include more details on how investment allocation decisions are made, the plan’s investment
policies and strategies, the major categories of plan assets, the inputs and valuation techniques used to measure
the fair value of plan assets, the effect of fair value measurements using significant unobservable inputs on
changes in plan assets for the period, and disclosure regarding significant concentrations of risk within plan
assets. The additional disclosure requirements are required for the Company’s Form 10-K for the period ended
September 30, 2010. The Company is currently evaluating the impact that adoption of this authoritative
guidance will have on its consolidated financial statement disclosures.

Effective with the June 30, 2009 Form 10-Q, the Company adopted the FASB authoritative guidance for
subsequent events that establishes general standards of accounting for and disclosure of events that occur after
the balance sheet date but before financial statements are issued or are available to be issued. Refer to Note R —
Subsequent Events for disclosures made as a result of the adoption of this guidance.

In June 2009, the FASB issued authoritative guidance that establishes the FASB Accounting Standards
CodificationTM (the Codification) as the source of authoritative GAAP recognized by the FASB to be applied by
all nongovernmental entities in the preparation of financial statements in conformity with GAAP. Rules and
interpretive releases of the SEC under authority of federal securities law are also sources of authoritative GAAP
for SEC registrants. All other nongrandfathered, non-SEC accounting literature not included in the Codification
will become nonauthoritative. The Codification was effective for interim and annual periods ending after
September 15, 2009. Effective with this September 30, 2009 Form 10-K, the Company has updated its
disclosures to conform to the Codification. There has been no impact on the Company’s consolidated financial
statements as the Codification does not change or alter existing GAAP.

Note B — Asset Retirement Obligations

The Company accounts for asset retirement obligations in accordance with the authoritative guidance that
requires entities to record the fair value of a liability for an asset retirement obligation in the period in which it is
incurred. An asset retirement obligation is defined as a legal obligation associated with the retirement of a
tangible long-lived asset in which the timing and/or method of settlement may or may not be conditional on a
future event that may or may not be within the control of the Company. When the liability is initially recorded,
the entity capitalizes the estimated cost of retiring the asset as part of the carrying amount of the related long-
lived asset. Over time, the liability is adjusted to its present value each period and the capitalized cost is
depreciated over the useful life of the related asset.

As previously disclosed, the Company follows the full cost method of accounting for its exploration and
production costs. In accordance with the current authoritative guidance for asset retirement obligations, the
Company has recorded an asset retirement obligation representing plugging and abandonment costs associated

81

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

with the Exploration and Production segment’s crude oil and natural gas wells and has capitalized such costs in
property, plant and equipment (i.e. the full cost pool). Under the current authoritative guidance for asset
retirement obligations, since plugging and abandonment costs are already included in the full cost pool, the
units-of-production depletion calculation excludes from the depletion base any estimate of future plugging and
abandonment costs that are already recorded in the full cost pool.

The full cost method of accounting provides a limit to the amount of costs that can be capitalized in the full
cost pool. This limit is referred to as the full cost ceiling. In accordance with current authoritative guidance,
since the full cost pool includes an amount associated with plugging and abandoning the wells, as discussed in
the preceding paragraph, the calculation of the full cost ceiling no longer reduces the future net cash flows from
proved oil and gas reserves by an estimate of plugging and abandonment costs.

In addition to the asset retirement obligation recorded in the Exploration and Production segment, the
Company has recorded future asset retirement obligations associated with the plugging and abandonment of
natural gas storage wells in the Pipeline and Storage segment and the removal of asbestos and asbestos-
containing material in various facilities in the Utility and Pipeline and Storage segments. The Company has also
recorded asset retirement obligations for certain costs connected with the retirement of distribution mains and
services pipeline systems in the Utility segment and with the transmission mains and other components in the
pipeline systems in the Pipeline and Storage segment. These retirement costs within the distribution and
transmission systems are primarily for the capping and purging of pipe, which are generally abandoned in place
when retired, as well as for the clean-up of PCB contamination associated with the removal of certain pipe.

A reconciliation of the Company’s asset retirement obligation is shown below:

(1) The Company recovers the cost of its regulatory assets but generally does not earn a return on them. There
are a few exceptions to this rule. For example, the Company does earn a return on Unrecovered Purchased
Gas Costs and, in the New York jurisdiction of its Utility segment, earns a return, within certain parameters,
on the excess of cumulative funding to the pension plan over the cumulative amount collected in rates.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Cost of Removal Regulatory Liability

In the Company’s Utility and Pipeline and Storage segments, costs of removing assets (i.e. asset retirement
costs) are collected from customers through depreciation expense. These amounts are not a legal retirement
obligation as discussed in Note B — Asset Retirement Obligations. Rather, they are classified as a regulatory
liability in recognition of the fact that the Company has collected dollars from the customer that will be used in
the future to fund asset retirement costs.

Tax Benefit on Medicare Part D Subsidy

The Company has established a regulatory liability for the tax benefit it will receive under the Medicare
Prescription Drug, Improvement, and Modernization Act of 2003 (the Act). The Act provides a federal subsidy
to sponsors of retiree health care benefit plans that provide a benefit that is at least actuarially equivalent to
Medicare Part D. In the Company’s Utility and Pipeline and Storage segments, the customer funds the
Company’s post-retirement benefit plans. As such, any tax benefit received under the Act must be flowed-
through to the customer. Refer to Note H — Retirement Plan and Other Post-Retirement Benefits for further
discussion of the Act and its impact on the Company.

Deferred Insurance Proceeds

The Company, in its Pipeline and Storage segment, has deferred environmental insurance settlement
proceeds amounting to $3.8 million and $3.9 million at September 30, 2009 and 2008, respectively. Such
proceeds have been deferred as a regulatory liability to be applied against any future environmental claims that
may be incurred. The proceeds have been classified as a regulatory liability in recognition of the fact that
customers funded the premiums on the former insurance policies.

NYPSC Assessment

On April 7, 2009, the Governor of the State of New York signed into law an amendment to the Public
Service Law increasing the allowed utility assessment from the current rate of one-third of one percent to one
percent of a utility’s in-state gross operating revenue, together with a temporary surcharge equal, as applied, to
an additional one percent of the utility’s gross operating revenue. The NYPSC, in a generic proceeding initiated
for the purpose of implementing the amended law, has authorized the recovery, through rates, of the full cost of
the increased assessment. The assessment is currently being applied to customer bills in the Utility segment’s
New York jurisdiction.

Off-System Sales and Capacity Release Credits

The Company, in its Utility segment, has entered into off-system sales and capacity release transactions.
Most of the margins on such transactions are returned to the customer with only a small percentage being
retained by the Company. The amount owed to the customer has been deferred as a regulatory liability.

As of September 30, 2009, the Company recorded a deferred tax asset relating to a federal net operating loss
carryover of $25.1 million. This carryover, which is available as a result of an acquisition, expires in varying
amounts between 2023 and 2029. Although this loss carryover is subject to certain annual limitations, no
valuation allowance was recorded because of management’s determination that the amount will be fully utilized
during the carryforward period.

Regulatory liabilities representing the reduction of previously recorded deferred income taxes associated
with rate-regulated activities that are expected to be refundable to customers amounted to $67.0 million and
$18.4 million at September 30, 2009 and 2008, respectively. Also, regulatory assets representing future amounts
collectible from customers, corresponding to additional deferred income taxes not previously recorded because

86

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

of prior ratemaking practices, amounted to $138.4 million and $82.5 million at September 30, 2009 and 2008,
respectively.

During fiscal 2009, consent was received from the Internal Revenue Service (IRS) National Office
approving the Company’s application to change its tax method of accounting for certain capitalized costs
relating to its utility property. Included in the regulatory liabilities and assets as of September 30, 2009 noted
above are liabilities of $47.3 million and assets of $51.1 million associated with this tax accounting method
change.

The Company adopted the FASB authoritative guidance for income tax uncertainties on October 1, 2007.
As of the date of adoption, a cumulative effect adjustment was recorded that resulted in a decrease to retained
earnings of $0.4 million. Upon adoption, the unrecognized tax benefits were $1.7 million.

A reconciliation of the change in unrecognized tax benefits for the year ended September 30, 2009 and

2008 is as follows:

The balance of $8.7 million as of September 30, 2009 relates to tax positions for which the ultimate
deductibility is highly certain but for which there is uncertainty about the timing of such deductibility. Due to
the impact of deferred tax accounting, other than interest and penalties, the disallowance of the shorter
deductibility period would not materially affect the annual effective tax rate but would accelerate the payment of
cash to the taxing authority to an earlier period. The Company anticipates that the unrecognized tax benefits
will not significantly change within the next twelve months.

The Company recognizes interest relating to income taxes in Other Interest Expense and penalties relating
to income taxes in Other Income. The Company did not recognize any interest expense related to income taxes
during fiscal 2009. The Company recognized interest expense related to income taxes of $0.5 million during
fiscal 2008. The Company has not accrued any penalties during fiscal 2009 and 2008.

The Company files U.S. federal and various state income tax returns. The IRS is currently conducting an
examination of the Company for fiscal 2009 in accordance with the Compliance Assurance Process (“CAP”).
The CAP audit employs a real time review of the Company’s books and tax records by the IRS that is intended to
permit issue resolution prior to the filing of the tax return. While the federal statute of limitations remains open
for fiscal 2006 and later years, IRS examinations for fiscal 2008 and prior years have been completed and the
Company believes such years are effectively settled.

The Company is also subject to various routine state income tax examinations. The Company’s operating
subsidiaries mainly operate in four states which have statutes of limitations that generally expire between three
to four years from the date of filing of the income tax return.

(1) Paid in Capital includes tax benefits of $5.9 million, $16.3 million and $13.7 million for September 30,

2009, 2008 and 2007, respectively, associated with the exercise of stock options.

(2) Paid in Capital includes compensation costs associated with stock option, stock-settled SARs and/or
restricted stock awards. The expense is included within Net Income Available For Common Stock, net of
tax benefits.

(3) The availability of consolidated earnings reinvested in the business for dividends payable in cash is limited
under terms of the indentures covering long-term debt. At September 30, 2009, $804.1 million of
accumulated earnings was free of such limitations.

Common Stock

The Company has various plans which allow shareholders, employees and others to purchase shares of the
Company common stock. The National Fuel Gas Company Direct Stock Purchase and Dividend Reinvestment
Plan allows shareholders to reinvest cash dividends and make cash investments in the Company’s common
stock and provides investors the opportunity to acquire shares of the Company common stock without the
payment of any brokerage commissions in connection with such acquisitions. The 401(k) Plans allow
employees the opportunity to invest in the Company common stock, in addition to a variety of other investment
alternatives. Generally, at the discretion of the Company, shares purchased under these plans are either original
issue shares purchased directly from the Company or shares purchased on the open market by an independent
agent.

During 2009, the Company issued 1,609,597 original issue shares of common stock as a result of stock
option exercises and 63,000 original issue shares for restricted stock awards (non-vested stock as defined in
existing guidance). Holders of stock options or restricted stock will often tender shares of common stock to the
Company for payment of option exercise prices and/or applicable withholding taxes. During 2009,
303,091 shares of common stock were tendered to the Company for such purposes. The Company considers
all shares tendered as cancelled shares restored to the status of authorized but unissued shares, in accordance
with New Jersey law.

The Company also has a director stock program under which it issues shares of Company common stock to
the eight non-employee directors of the Company who receive compensation under the Company’s Retainer
Policy for Non-Employee Directors, as partial consideration for the directors’ services. Under this program, the
Company issued 9,865 original issue shares of common stock during 2009.

In December 2005, the Company’s Board of Directors authorized the Company to implement a share
repurchase program, whereby the Company may repurchase outstanding shares of common stock, up to an
aggregate amount of eight million shares in the open market or through privately negotiated transactions. The
Company completed the repurchase of the eight million shares during 2008 for a total program cost of
$324.2 million (of which 4,165,122 shares were repurchased during the year ended September 30, 2008 for
$191.0 million). In September 2008, the Company’s Board of Directors authorized the repurchase of an
additional eight million shares. Under this new authorization, the Company repurchased 1,028,981 shares for
$46.0 million through September 17, 2008. The Company, however, stopped repurchasing shares after
September 17, 2008 in light of the unsettled nature of the credit markets. Such repurchases may be made
in the future. The share repurchases mentioned above were funded with cash provided by operating activities
and/or through the use of the Company’s lines of credit.

Shareholder Rights Plan

In 1996, the Company’s Board of Directors adopted a shareholder rights plan (Plan). The Plan has been
amended several times since it was adopted and is now embodied in an Amended and Restated Rights

89

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Agreement effective December 4, 2008, a copy of which was included as an exhibit to the Form 8-K filed by the
Company on December 4, 2008.

Pursuant to the Plan, the holders of the Company’s common stock have one right (Right) for each of their
shares. Each Right is initially evidenced by the Company’s common stock certificates representing the
outstanding shares of common stock.

The Rights have anti-takeover effects because they will cause substantial dilution of the Company’s
common stock if a person attempts to acquire the Company on terms not approved by the Board of Directors (an
Acquiring Person).

The Rights become exercisable upon the occurrence of a Distribution Date as described below, but after a
Distribution Date Rights that are owned by an Acquiring Person will be null and void. At any time following a
Distribution Date, each holder of a Right may exercise its right to receive, upon payment of an amount
calculated under the Rights Agreement, common stock of the Company (or, under certain circumstances, other
securities or assets of the Company) having a value equal to two times the amount paid to exercise the Right.
However, the Rights are subject to redemption or exchange by the Company prior to their exercise as described
below.

A Distribution Date would occur upon the earlier of (i) ten days after the public announcement that a
person or group has acquired, or obtained the right to acquire, beneficial ownership of the Company’s common
stock or other voting stock (including Synthetic Long Positions as defined in the Plan) having 10% or more of
the total voting power of the Company’s common stock and other voting stock and (ii) ten days after the
commencement or announcement by a person or group of an intention to make a tender or exchange offer that
would result in that person acquiring, or obtaining the right to acquire, beneficial ownership of the Company’s
common stock or other voting stock having 10% or more of the total voting power of the Company’s common
stock and other voting stock.

In certain situations after a person or group has acquired beneficial ownership of 10% or more of the total
voting power of the Company’s stock as described above, each holder of a Right will have the right to exercise its
Rights to receive, upon exercise of the right, common stock of the acquiring company having a value equal to
two times the amount paid to exercise the right. These situations would arise if the Company is acquired in a
merger or other business combination or if 50% or more of the Company’s assets or earning power are sold or
transferred.

At any time prior to the end of the business day on the tenth day following the Distribution Date, the
Company may redeem the Rights in whole, but not in part, at a price of $0.005 per Right, payable in cash or
stock. A decision to redeem the Rights requires the vote of 75% of the Company’s full Board of Directors. Also, at
any time following the Distribution Date, 75% of the Company’s full Board of Directors may vote to exchange the
Rights, in whole or in part, at an exchange rate of one share of common stock, or other property deemed to have
the same value, per Right, subject to certain adjustments.

Upon exercise of the Rights, the Company may need additional regulatory approvals to satisfy the
requirements of the Rights Agreement. The Rights will expire on July 31, 2018, unless earlier than that date,
they are exchanged or redeemed or the Plan is amended to extend the expiration date.

Stock Option and Stock Award Plans

The Company has various stock option and stock award plans which provide or provided for the issuance
of one or more of the following to key employees: incentive stock options, nonqualified stock options, stock-
settled SARs, restricted stock, performance units or performance shares. Stock options and stock-settled SARs
under all plans have exercise prices equal to the average market price of Company common stock on the date of

Restricted Share Awards

Restricted stock is subject to restrictions on vesting and transferability. Restricted stock awards entitle the
participants to full dividend and voting rights. The market value of restricted stock on the date of the award is
recorded as compensation expense over the vesting period. Certificates for shares of restricted stock awarded
under the Company’s stock option and stock award plans are held by the Company during the periods in which
the restrictions on vesting are effective.

In April 2009, the Company issued $250.0 million of 8.75% notes due in May 2019. After deducting
underwriting discounts and commissions, the net proceeds to the Company amounted to $247.8 million. These
notes were registered under the Securities Act of 1933. The holders of the notes may require the Company to
repurchase their notes at a price equal to 101% of the principal amount in the event of both a change in control
and a ratings downgrade to a rating below investment grade. The proceeds of this debt issuance were used for
general corporate purposes, including to replenish cash that was used to pay the $100 million due at the
maturity of the Company’s 6.0% medium-term notes on March 1, 2009.

In April 2008, the Company issued $300.0 million of 6.50% senior, unsecured notes in a private placement
exempt from registration under the Securities Act of 1933. In February 2009, the Company exchanged the notes
for economically identical notes registered under the Securities Act of 1933. The notes have a term of 10 years,
with a maturity date in April 2018. The holders of the notes may require the Company to repurchase their notes
at a price equal to 101% of the principal amount in the event of both a change in control and a ratings downgrade
to a rating below investment grade. The Company used $200.0 million of the proceeds of the issuance to refund
$200.0 million of 6.303% medium-term notes that matured on May 27, 2008.

As of September 30, 2009, the aggregate principal amounts of long-term debt maturing during the next five
years and thereafter are as follows: zero in 2010, $200.0 million in 2011, $150.0 million in 2012, $250.0 million
in 2013, zero in 2014, and $649.0 million thereafter.

Short-Term Borrowings

The Company historically has obtained short-term funds either through bank loans or the issuance of
commercial paper. As for the former, the Company maintains a number of individual uncommitted or
discretionary lines of credit with certain financial institutions for general corporate purposes. Borrowings
under these lines of credit are made at competitive market rates. These credit lines, which aggregate to
$420.0 million, are revocable at the option of the financial institutions and are reviewed on an annual basis. The
Company anticipates that these lines of credit will continue to be renewed, or replaced by similar lines. The total
amount available to be issued under the Company’s commercial paper program is $300.0 million. The
commercial paper program is backed by a syndicated committed credit facility totaling $300.0 million that
extends through September 30, 2010.

At September 30, 2009 and 2008, the Company had no outstanding short-term notes payable to banks or

commercial paper.

Debt Restrictions

Under the Company’s committed credit facility, the Company has agreed that its debt to capitalization ratio
will not exceed .65 at the last day of any fiscal quarter through September 30, 2010. At September 30, 2009, the
Company’s debt to capitalization ratio (as calculated under the facility) was .44. The constraints specified in the
committed credit facility would permit an additional $1.7 billion in short-term and/or long-term debt to be
outstanding (further limited by the indenture covenants discussed below) before the Company’s debt to
capitalization ratio would exceed .65. If a downgrade in any of the Company’s credit ratings were to occur,
access to the commercial paper markets might not be possible. However, the Company expects that it could
borrow under its committed credit facility, uncommitted bank lines of credit or rely upon other liquidity
sources, including cash provided by operations.

Under the Company’s existing indenture covenants, at September 30, 2009, the Company would have been
permitted to issue up to a maximum of $435.0 million in additional long-term unsecured indebtedness at then
current market interest rates in addition to being able to issue new indebtedness to replace maturing debt. If the
Company were to experience another impairment of oil and gas properties in the future, it is possible that these
indenture covenants would restrict the Company’s ability to issue additional long-term unsecured indebtedness.
This would not preclude the Company from issuing new indebtedness to replace maturing debt.

The Company’s 1974 indenture pursuant to which $99.0 million (or 7.9%) of the Company’s long-term
debt (as of September 30, 2009) was issued, contains a cross-default provision whereby the failure by the
Company to perform certain obligations under other borrowing arrangements could trigger an obligation to
repay the debt outstanding under the indenture. In particular, a repayment obligation could be triggered if the
Company fails (i) to pay any scheduled principal or interest on any debt under any other indenture or
agreement, or (ii) to perform any other term in any other such indenture or agreement, and the effect of the
failure causes, or would permit the holders of the debt to cause, the debt under such indenture or agreement to
become due prior to its stated maturity, unless cured or waived.

The Company’s $300.0 million committed credit facility also contains a cross-default provision whereby
the failure by the Company or its significant subsidiaries to make payments under other borrowing arrange-
ments, or the occurrence of certain events affecting those other borrowing arrangements, could trigger an
obligation to repay any amounts outstanding under the committed credit facility. In particular, a repayment
obligation could be triggered if (i) the Company or any of its significant subsidiaries fail to make a payment
when due of any principal or interest on any other indebtedness aggregating $20.0 million or more, or (ii) an
event occurs that causes, or would permit the holders of any other indebtedness aggregating $20.0 million or
more to cause, such indebtedness to become due prior to its stated maturity. As of September 30, 2009, the
Company had no debt outstanding under the committed credit facility.

Note F — Fair Value Measurements

Beginning in fiscal 2009, the Company adopted the FASB authoritative guidance regarding fair value
measurements which establishes a fair-value hierarchy and prioritizes the inputs used in valuation techniques
that measure fair value. Those inputs are prioritized into three levels. Level 1 inputs are unadjusted quoted
prices in active markets for assets or liabilities that the Company has the ability to access at the measurement
date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset
or liability, either directly or indirectly at the measurement date. Level 3 inputs are unobservable inputs for the
asset or liability at the measurement date. The Company’s assessment of the significance of a particular input to
the fair value measurement requires judgment, and may affect the valuation of fair value assets and liabilities and
their placement within the fair value hierarchy levels. The adoption of this authoritative guidance regarding fair
value measurements has not had a significant impact on the consolidated financial statements.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The following table sets forth, by level within the fair value hierarchy, the Company’s financial assets and
liabilities that were accounted for at fair value on a recurring basis as of September 30, 2009. Financial assets and
liabilities are classified in their entirety based on the lowest level of input that is significant to the fair value
measurement.

Cash Equivalents

The cash equivalents reported in Level 1 consist of SEC registered money market mutual funds.

Derivative Financial Instruments

The derivative financial instruments reported in Level 1 consist of NYMEX futures contracts. The hedging
collateral deposits associated with these futures contracts have been reported in Level 1 as well. The derivative
financial instruments reported in Level 2 consist of natural gas swap agreements used in the Company’s
Exploration and Production segment and natural gas swap agreements used in the Energy Marketing segment.
The fair value of these natural gas swap agreements is based on an internal model that uses observable inputs.
The fair market value of the price swap agreements reported in Level 2 as assets has been reduced by
$0.2 million based on an assessment of counterparty credit risk. The derivative financial instruments reported in
Level 3 consist of all of the Exploration and Production segment’s crude oil swap agreements. The fair value of
the crude oil swap agreements is based on an internal model that uses both observable and unobservable inputs.
The fair market value of the price swap agreements reported in Level 3 as assets has been reduced by
$0.7 million based on an assessment of counterparty credit risk. The fair market value of the price swap
agreements reported in Level 2 as liabilities has been reduced by less than $0.1 million based on an assessment of
the Company’s credit risk. This credit reserve, as well as the credit reserve established for the Level 2 and Level 3
swap agreement assets, was determined by applying default probabilities to the anticipated cash flows that the
Company is either expecting from its counterparties or expecting to pay to its counterparties.

Other Investments

The other investments reported in Level 1 consist of publicly traded equity securities and a publicly traded

balanced equity mutual fund.

The table listed below provides a reconciliation of the beginning and ending net balances for assets and

liabilities measured at fair value and classified as Level 3.

Note G — Financial Instruments

Long-Term Debt

At September 30, 2009, the fair market value of the Company’s debt, as presented in the table below, was
determined using a discounted cash flow model, which incorporates the Company’s credit risk in determining
the yield, and subsequently, the fair market value of the debt. At September 30, 2008, the fair market value of the
Company’s long-term debt was determined based on quoted market prices of similar issues having the same
remaining maturities, redemption terms and credit ratings. Based on these criteria, the fair market value of long-
term debt, including current portion, was as follows:

The fair value amounts are not intended to reflect principal amounts that the Company will ultimately be
required to pay. Carrying amounts for other financial instruments recorded on the Company’s Consolidated
Balance Sheets approximate fair value.

Other Investments

Investments in life insurance are stated at their cash surrender values or net present value as discussed
below. Investments in an equity mutual fund and the stock of an insurance company (marketable equity
securities), as discussed below, are stated at fair value based on quoted market prices.

Other investments include cash surrender values of insurance contracts (net present value in the case of
split-dollar collateral assignment arrangements) and marketable equity securities. The values of the insurance
contracts amounted to $54.2 million and $53.6 million at September 30, 2009 and 2008, respectively. The fair
value of the equity mutual fund was $15.8 million and $12.4 million at September 30, 2009 and 2008,

96

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

respectively. The gross unrealized loss on this equity mutual fund was $1.0 million at September 30, 2009 and
September 30, 2008. Although this investment has been in an unrealized loss position for over twelve months,
management has the intent and ability to hold the investment for a sufficient period of time for the asset to
recover in value. As such, management does not consider this investment to be other than temporarily impaired.
The fair value of the stock of an insurance company was $8.3 million and $14.5 million at September 30, 2009
and 2008, respectively. The gross unrealized gain on this stock was $5.9 million and $12.1 million at
September 30, 2009 and 2008, respectively. The insurance contracts and marketable equity securities are
primarily informal funding mechanisms for various benefit obligations the Company has to certain employees.

Derivative Financial Instruments

The Company is exposed to certain risks relating to its ongoing business operations. The primary risk
managed by using derivative instruments is commodity price risk in the Exploration and Production and Energy
Marketing segments. The Company enters into futures contracts and over-the-counter swap agreements for
natural gas and crude oil to manage the price risk associated with forecasted sales of gas and oil. The Company
also enters into futures contracts and swaps to manage the risk associated with forecasted gas purchases, storage
of gas, and withdrawal of gas from storage to meet customer demand. The duration of the Company’s hedges do
not typically exceed 3 years and the majority of the positions settle within one year.

The Company has presented its net derivative assets and liabilities on its Consolidated Balance Sheet at

Cash Flow Hedges

For derivative instruments that are designated and qualify as a cash flow hedge, the effective portion of the
gain or loss on the derivative is reported as a component of other comprehensive income and reclassified into
earnings in the same period or periods during which the hedged transaction affects earnings. Gains and losses
on the derivative representing either hedge ineffectiveness or hedge components excluded from the assessment
of effectiveness are recognized in current earnings.

As of September 30, 2009, the Company’s Exploration and Production segment had the following
commodity derivative contracts (swaps) outstanding to hedge forecasted sales (where the Company uses short

($21.3 million after tax) of gains included in the accumulated other comprehensive income balance. It is
expected that $36.4 million ($21.4 million after tax) of these gains will be reclassified into income within the
next 12 months as the sales of the underlying commodities are expected to occur. See Note A, under
Accumulated Other Comprehensive Income (Loss), for the after-tax gain pertaining to derivative financial
instruments (Net Unrealized Gain on Derivative Financial Instruments in Note A includes both the Exploration
and Production and Energy Marketing segments).

As of September 30, 2009, the Company’s Energy Marketing segment had $4.7 million ($2.8 million after
tax) of losses included in the accumulated other comprehensive income (loss) balance. It is expected that
$4.7 million ($2.8 million after tax) of these losses will be reclassified into income within the next 12 months as
the sales and purchases of the underlying commodities occur. See Note A, under Accumulated Other Com-
prehensive Income (Loss), for the after-tax gain pertaining to derivative financial instruments (Net Unrealized

Fair value hedges

The Company’s Energy Marketing segment utilizes fair value hedges to mitigate risk associated with fixed
price sales commitments, fixed price purchase commitments, and commitments related to the injection and
withdrawal of storage gas. In order to hedge fixed price sales commitments, the Company enters into long
positions to mitigate the risk that after the Company enters into fixed price sales agreements with its customers,
the price of natural gas increases (thereby passing up the opportunity for higher operating revenue). With fixed
price purchase commitments, the Company enters into short positions to mitigate the risk that after the
Company locks into fixed price purchase deals with its suppliers, the price of natural gas decreases (thereby
passing up the opportunity for lower purchased gas expense). Fair value hedges related to the injection and
withdrawal of storage gas impact purchased gas expense. As of September 30, 2009, the Company’s Energy
Marketing segment had fair value hedges covering approximately 13.0 Bcf (11.7 Bcf of fixed price sales
commitments (all long positions), 0.9 Bcf of fixed price purchase commitments (all short positions), and 0.4 Bcf
of commitments related to the withdrawal of storage gas (all short positions)). For derivative instruments that
are designated and qualify as a fair value hedge, the gain or loss on the derivative as well as the offsetting gain or
loss on the hedged item attributable to the hedged risk completely offset each other in current earnings, as
shown below.

The Company may be exposed to credit risk on any of the derivative financial instruments that are in a gain
position. Credit risk relates to the risk of loss that the Company would incur as a result of nonperformance by
counterparties pursuant to the terms of their contractual obligations. To mitigate such credit risk, management
performs a credit check, and then on a quarterly basis monitors counterparty credit exposure. The majority of
the Company’s counterparties are financial institutions and energy traders. The Company has over-the-counter
swap positions with ten counterparties. At September 30, 2009, the Company had derivative financial
instruments that were in gain positions with eight of the counterparties. The Company had derivative financial
instruments that were in loss positions with the other two counterparties. The Company had $26.6 million of
credit exposure with one counterparty (which is rated A1 (Moody’s Investor Service), A (S&P), and A+ (Fitch
Ratings Service) as of September 30, 2009). On average for those financial instruments that were in a gain
position, the Company had $1.8 million of credit exposure per counterparty with the other seven counterparties
that were in a gain position. The Company had not received any collateral from the counterparties at
September 30, 2009 since the Company’s gain position on such derivative financial instruments had not
exceeded the established thresholds at which the counterparties would be required to post collateral.

As of September 30, 2009, eight of the ten counterparties to the Company’s outstanding derivative
instrument contracts (specifically the over-the-counter swaps) had a common credit-risk-related contingency
feature. In the event the Company’s credit rating increases or falls below a certain threshold (the lower of the
S&P or Moody’s Debt Rating), the available credit extended to the Company would either increase or decrease.
A decline in the Company’s credit rating, in and of itself, would not cause the Company to be required to
increase the level of its hedging collateral deposits (in the form of cash deposits, letters of credit or treasury debt
instruments). If the Company’s outstanding derivative instrument contracts were in a liability position and the
Company’s credit rating declined, then additional hedging collateral deposits would be required. At Septem-
ber 30, 2009, these credit-risk related contingency features were not triggered since the Company had assets of
$37.9 million related to derivative financial instruments with the eight counterparties.

For its exchange traded futures contracts, which are in an asset position, the Company had paid
$0.8 million in hedging collateral as of September 30, 2009. As these are exchange traded futures contracts,
there are no specific credit-risk related contingency features. The Company posts hedging collateral based on
open positions (i.e. those positions that have been settled for cash) and margin requirements. (This is discussed
in Note A under Hedging Collateral Deposits.)

Note H — Retirement Plan and Other Post-Retirement Benefits

The Company has a tax-qualified, noncontributory, defined-benefit retirement plan (Retirement Plan) that
covers a majority of the full-time employees of the Company. The Retirement Plan covers certain non-
collectively bargained employees hired before July 1, 2003 and certain collectively bargained employees hired
before November 1, 2003. Employees hired after June 30, 2003 are eligible for a Retirement Savings Account
benefit provided under the Company’s defined contribution Tax-Deferred Savings Plans. Costs associated with
the Retirement Savings Account were $0.4 million, $0.2 million and $0.2 million for the years ended
September 30, 2009, 2008 and 2007, respectively. Costs associated with the Company’s contributions to the
Tax-Deferred Savings Plans were $4.1 million, $4.0 million, and $4.1 million for the years ended September 30,
2009, 2008 and 2007, respectively.

The Company provides health care and life insurance benefits (other post-retirement benefits) for a
majority of its retired employees. The other post-retirement benefits cover certain non-collectively bargained
employees hired before January 1, 2003 and certain collectively bargained employees hired before October 31,
2003.

The Company’s policy is to fund the Retirement Plan with at least an amount necessary to satisfy the
minimum funding requirements of applicable laws and regulations and not more than the maximum amount
deductible for federal income tax purposes. The Company has established VEBA trusts for its other post-
retirement benefits. Contributions to the VEBA trusts are tax deductible, subject to limitations contained in the
Internal Revenue Code and regulations and are made to fund employees’ other post-retirement benefits, as well
as benefits as they are paid to current retirees. In addition, the Company has established 401(h) accounts for its
other post-retirement benefits. They are separate accounts within the Retirement Plan trust used to pay retiree
medical benefits for the associated participants in the Retirement Plan. Although these accounts are in the
Retirement Plan trust, for funding status purposes as shown below, the 401(h) accounts are included in Fair
Value of Assets under Other Post-Retirement Benefits. Contributions are tax-deductible when made, subject to
limitations contained in the Internal Revenue Code and regulations. Retirement Plan, VEBA trust and 401(h)
account assets primarily consist of equity and fixed income investments or units in commingled funds or money
market funds.

The expected return on plan assets, a component of net periodic benefit cost shown in the tables below, is
applied to the market-related value of plan assets. The market-related value of plan assets is equal to market
value as of the measurement date.

Reconciliations of the Benefit Obligations, Plan Assets and Funded Status, as well as the components of Net
Periodic Benefit Cost and the Weighted Average Assumptions of the Retirement Plan and other post-retirement
benefits are shown in the tables below. The date used to measure the Benefit Obligations, Plan Assets and
Funded Status is September 30, 2009, June 30, 2008 and June 30, 2007, for fiscal year 2009, 2008 and 2007,
respectively.

(1) In fiscal 2008 and 2009, the Company passed amendments, for most of the subsidiaries, which increased
the participant contributions for active employees at the time of the amendment. This decreased the benefit
obligation.

(2) Distribution Corporation’s New York jurisdiction calculates the amortization of the actuarial loss on a
vintage year basis over 10 years, as mandated by the NYPSC. All the other subsidiaries of the Company
utilize the corridor approach.

The Net Periodic Benefit Cost in the table above includes the effects of regulation. The Company recovers
pension and other post-retirement benefit costs in its Utility and Pipeline and Storage segments in accordance
with the applicable regulatory commission authorizations. Certain of those commission authorizations estab-
lished tracking mechanisms which allow the Company to record the difference between the amount of pension
and other post-retirement benefit costs recoverable in rates and the amounts of such costs as determined under
the existing authoritative guidance as either a regulatory asset or liability, as appropriate. Any activity under the
tracking mechanisms (including the amortization of pension and other post-retirement regulatory assets and
liabilities) is reflected in the Net Amortization and Deferral for Regulatory Purposes line item above.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

As note above, through 2008, the Company used June 30th as the measurement date for financial reporting
purposes. In 2009, in accordance with the current authoritative guidance for defined benefit pension and other
postretirement plans, the Company began measuring the Plan’s assets and liabilities for its pension and other
post-retirement benefit plans as of September 30th, its fiscal year end. In making this change and as permitted by
the current authoritative guidance, the Company recorded fifteen months of pension and post-retirement
benefits expense (for the period from July 1, 2008 through September 30, 2009) during the fiscal year ended
September 30, 2009. The pension and other post-retirement benefit costs for the period of July 1, 2008 to
September 30, 2008 amounted to $3.8 million and were recorded by the Company during the year ended
September 30, 2009 as a $3.4 million increase to Other Regulatory Assets in the Company’s Utility and Pipeline
and Storage segments and a $0.4 million ($0.2 million after tax) adjustment to earnings reinvested in the
business. In addition, for the Company’s non-qualified benefit plan, benefit costs of $1.3 million were recorded
by the Company during the year ended September 30, 2009 as a $0.4 million increase to Other Regulatory Assets
in the Company’s Utility segment and a $0.9 million ($0.6 million after tax) adjustment to earnings reinvested in
the business.

The cumulative amounts recognized in accumulated other comprehensive income (loss), regulatory assets,
and regulatory liabilities through fiscal 2009, the changes in such amounts during 2009, as well as the amounts
expected to be recognized in net periodic benefit cost in fiscal 2010 are presented in the table below:

In order to adjust the funded status of its pension and other post-retirement benefit plans at September 30,
2009, the Company recorded a $318.4 million increase to Other Regulatory Assets in the Company’s Utility and

104

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

Pipeline and Storage segments and a $70.8 million (pre-tax) increase to Accumulated Other Comprehensive
Loss.

The effect of the discount rate change for the Retirement Plan in 2009 was to increase the projected benefit
obligation of the Retirement Plan by $102.6 million. The effect of the discount rate change for the Retirement
Plan in 2008 was to decrease the projected benefit obligation of the Retirement Plan by $38.6 million. In 2007,
there was no change to the discount rate used to estimate the projected benefit obligation for the Retirement
Plan.

The Company made cash contributions totaling $16.0 million to the Retirement Plan during the year ended
September 30, 2009. The Company expects that the annual contribution to the Retirement Plan in 2010 will be
in the range of $20.0 million to $30.0 million. It is likely that the Company will have to fund larger amounts to
the Retirement Plan subsequent to 2010 in order to be in compliance with the Pension Protection Act of 2006.

The following benefit payments, which reflect expected future service, are expected to be paid during the
next five years and the five years thereafter: $51.8 million in 2010; $52.2 million in 2011; $52.6 million in 2012;
$53.3 million in 2013; $54.4 million in 2014; and $294.3 million in the five years thereafter.

In addition to the Retirement Plan discussed above, the Company also has a Non-Qualified benefit plan
that covers a group of management employees designated by the Chief Executive Officer of the Company. This
plan provides for defined benefit payments upon retirement of the management employee, or to the spouse
upon death of the management employee. The net periodic benefit cost associated with this plan was
$5.2 million, $5.0 million and $5.5 million in 2009, 2008 and 2007, respectively. At September 30, 2007,
an $8.0 million (pre-tax) loss was recognized in accumulated other comprehensive income (loss) on the
Consolidated Balance Sheet upon adoption of the FASB revised authoritative guidance for defined benefit
pension and other postretirement plans. The accumulated benefit obligation for this plan was $35.8 million and
$31.8 million at September 30, 2009 and 2008, respectively. The projected benefit obligation for the plan was
$60.3 million and $47.5 million at September 30, 2009 and 2008, respectively. The actuarial valuations for this
plan were determined based on a discount rate of 5.25%, 6.75% and 6.25% as of September 30, 2009, 2008 and
2007, respectively; a rate of compensation increase of 10.0% as of September 30, 2009, 2008 and 2007; and an
expected long-term rate of return on plan assets of 8.25% at September 30, 2009, 2008 and 2007.

The effect of the discount rate change in 2009 was to increase the other post-retirement benefit obligation
by $60.9 million. Effective October 1, 2009, the Medicare Part B reimbursement trend, prescription drug trend
and medical trend assumptions were changed. The effect of these assumption changes was to increase the other
post-retirement benefit obligation by $27.0 million. Other actuarial experience decreased the other post-
retirement benefit obligation in 2009 by $32.1 million.

The effect of the discount rate change in 2008 was to decrease the other post-retirement benefit obligation
by $26.3 million. Effective July 1, 2008, the Medicare Part B reimbursement trend, prescription drug trend and
medical trend assumptions were changed. The effect of these assumption changes was to increase the other post-
retirement benefit obligation by $20.0 million. Other actuarial experience decreased the other post-retirement
benefit obligation in 2008 by $8.1 million.

There was no change to the discount rate used to estimate the other post-retirement benefit obligation
during 2007. Effective July 1, 2007, the Medicare Part B reimbursement trend, prescription drug trend and
medical trend assumptions were changed. The effect of these assumption changes was to increase the other post-
retirement benefit obligation by $8.6 million. Other actuarial experience decreased the other post-retirement
benefit obligation in 2007 by $23.0 million.

On December 8, 2003, the Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (the
Act) was signed into law. This Act introduced a prescription drug benefit under Medicare (Medicare Part D), as
well as a federal subsidy to sponsors of retiree health care benefit plans that provide a benefit that is at least

105

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

actuarially equivalent to Medicare Part D. Since the Company is assumed to continue to provide a prescription
drug benefit to retirees in the point of service and indemnity plans that is at least actuarially equivalent to
Medicare Part D, the impact of the Act was reflected as of December 8, 2003.

The estimated gross other post-retirement benefit payments and gross amount of Medicare Part D

prescription drug subsidy receipts are as follows:

(3) It was assumed that this rate would gradually decline to 5.0% by 2014.

(4) It was assumed that this rate would gradually decline to 5.0% by 2016.

The health care cost trend rate assumptions used to calculate the per capita cost of covered medical care
benefits have a significant effect on the amounts reported. If the health care cost trend rates were increased by
1% in each year, the other post-retirement benefit obligation as of October 1, 2009 would increase by
$54.5 million. This 1% change would also have increased the aggregate of the service and interest cost
components of net periodic post-retirement benefit cost for 2009 by $3.9 million. If the health care cost trend
rates were decreased by 1% in each year, the other post-retirement benefit obligation as of October 1, 2009
would decrease by $46.2 million. This 1% change would also have decreased the aggregate of the service and
interest cost components of net periodic post-retirement benefit cost for 2009 by $3.3 million.

The Company made cash contributions totaling $25.5 million to the VEBA trusts and 401(h) accounts
during the year ended September 30, 2009. In addition, the Company made direct payments of $0.2 million to
retirees not covered by the VEBA trusts and 401(h) accounts during the year ended September 30, 2009. The
Company expects that the annual contribution to the VEBA trusts and 401(h) accounts in 2010 will be in the
range of $25.0 million to $30.0 million.

The Company’s assumption regarding the expected long-term rate of return on plan assets is 8.25%. The
return assumption reflects the anticipated long-term rate of return on the plan’s current and future assets. The
Company utilizes historical investment data, projected capital market conditions, and the plan’s target asset
class and investment manager allocations to set the assumption regarding the expected return on plan assets.

The long-term investment objective of the Retirement Plan trust, the VEBA trusts and the 401(h) accounts
is to achieve the target total return in accordance with the Company’s risk tolerance. Assets are diversified
utilizing a mix of equities, fixed income and other securities (including real estate). Risk tolerance is established
through consideration of plan liabilities, plan funded status and corporate financial condition.

Investment managers are retained to manage separate pools of assets. Comparative market and peer group
performance of individual managers and the total fund are monitored on a regular basis, and reviewed by the
Company’s Retirement Committee on at least a quarterly basis.

The discount rate which is used to present value the future benefit payment obligations of the Retirement
Plan and the Company’s other post-retirement benefits is 5.50% as of September 30, 2009. The discount rate
which is used to present value the future benefit payment obligations of the Non-Qualified benefit plan is 5.25%
as of September 30, 2009. The Company utilizes a yield curve model to determine the discount rate. The yield
curve is a spot rate yield curve that provides a zero-coupon interest rate for each year into the future. Each year’s
anticipated benefit payments are discounted at the associated spot interest rate back to the measurement date.
The discount rate is then determined based on the spot interest rate that results in the same present value when
applied to the same anticipated benefit payments.

identify potential environmental exposures and to comply with regulatory policies and procedures.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

It is the Company’s policy to accrue estimated environmental clean-up costs (investigation and remedia-
tion) when such amounts can reasonably be estimated and it is probable that the Company will be required to
incur such costs. At September 30, 2009, the Company has estimated its remaining clean-up costs related to
former manufactured gas plant sites and third party waste disposal sites will be in the range of $18.7 million to
$22.9 million. The minimum estimated liability of $18.7 million has been recorded on the Consolidated Balance
Sheet at September 30, 2009. The Company expects to recover its environmental clean-up costs from a
combination of rate recovery and deferred insurance proceeds that are currently recorded as a regulatory
liability on the Consolidated Balance Sheet (refer to Note C — Regulatory Matters for further discussion of the
insurance proceeds). Other than as discussed below, the Company is currently not aware of any material
exposure to environmental liabilities. However, changes in environmental regulations, new information or
other factors could adversely impact the Company.

(i) Former Manufactured Gas Plant Sites

The Company has incurred investigation and/or clean-up costs at several former manufactured gas plant
sites in New York and Pennsylvania. The Company continues to be responsible for future ongoing monitoring
and long-term maintenance at two sites.

The Company has agreed with the NYDEC to remediate another former manufactured gas plant site located
in New York. The Company has received approval from the NYDEC of a Remedial Design work plan for this site
and has recorded an estimated minimum liability for remediation of this site of $15.7 million.

(ii) Other

In June 2007, the NYDEC notified the Company, as well as a number of other companies, of their potential
liability with respect to a remedial action at a waste disposal site in New York. The notification identified the
Company as one of approximately 500 other companies considered to be PRPs related to this site and requested
that the remedy the NYDEC proposed in a Record of Decision issued in March 2006 be performed. The
estimated clean-up costs under the remedy selected by the NYDEC are estimated to be approximately
$13.0 million if implemented. The Company participates in an organized group with other PRPs who are
addressing this site.

Other

The Company, in its Utility segment, Energy Marketing segment, and All Other category, has entered into
contractual commitments in the ordinary course of business, including commitments to purchase gas, trans-
portation, and storage service to meet customer gas supply needs. Substantially all of these contracts expire
within the next five years. The future gas purchase, transportation and storage contract commitments during the
next five years and thereafter are as follows: $520.2 million in 2010, $101.8 million in 2011, $66.6 million in
2012, $40.2 million in 2013, $39.8 million in 2014, and $76.3 million thereafter. Gas prices within the gas
purchase contracts are variable based on NYMEX prices adjusted for basis. In the Utility segment, these costs are
subject to state commission review, and are being recovered in customer rates. Management believes that, to the
extent any stranded pipeline costs are generated by the unbundling of services in the Utility segment’s service
territory, such costs will be recoverable from customers.

The Company has entered into leases for the use of buildings, vehicles, construction tools, meters,
computer equipment and other items. These leases are accounted for as operating leases. The future lease
commitments during the next five years and thereafter are as follows: $5.4 million in 2010, $3.9 million in 2011,
$3.3 million in 2012, $2.4 million in 2013, $2.3 million in 2014, and $10.5 million thereafter.

The Company is involved in other litigation arising in the normal course of business. In addition to the
regulatory matters discussed in Note C — Regulatory Matters, the Company is involved in other regulatory

108

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

matters arising in the normal course of business. These other litigation and regulatory matters may include, for
example, negligence claims and tax, regulatory or other governmental audits, inspections, investigations and
other proceedings. These matters may involve state and federal taxes, safety, compliance with regulations, rate
base, cost of service and purchased gas cost issues, among other things. While these normal-course matters
could have a material effect on earnings and cash flows in the period in which they are resolved, they are not
expected to change materially the Company’s present liquidity position, nor are they expected to have a material
adverse effect on the financial condition of the Company.

Note J — Discontinued Operations

On August 31, 2007, the Company, in its Exploration and Production segment, completed the sale of SECI,
Seneca’s wholly owned subsidiary that operated in Canada. The Company received approximately
$232.1 million of proceeds from the sale, of which $58.0 million was placed in escrow pending receipt of a
tax clearance certificate from the Canadian government. In December 2007, the Canadian government issued
the tax clearance certificate, thereby releasing the proceeds from restriction as of December 31, 2007. The sale
resulted in the recognition of a gain of approximately $120.3 million, net of tax, during the fourth quarter of
2007. SECI engaged in the exploration for, and the development and purchase of, natural gas and oil reserves in
the provinces of Alberta, Saskatchewan and British Columbia in Canada. The decision to sell was based on lower
than expected returns from the Canadian oil and gas properties combined with difficulty in finding significant
new reserves. Seneca will continue its exploration and development activities in the United States, primarily in
Appalachia and California. As a result of the decision to sell SECI, the Company began presenting all SECI
operations as discontinued operations during the fourth quarter of 2007.

The following is selected financial information of the discontinued operations for SECI:

Note K — Business Segment Information

The Company has four reportable segments: Utility, Pipeline and Storage, Exploration and Production, and
Energy Marketing. The division of the Company’s operations into reportable segments is based upon a
combination of factors including differences in products and services, regulatory environment and geographic
factors.

The Utility segment operations are regulated by the NYPSC and the PaPUC and are carried out by
Distribution Corporation. Distribution Corporation sells natural gas to retail customers and provides natural
gas transportation services in western New York and northwestern Pennsylvania.

109

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The Pipeline and Storage segment operations are regulated by the FERC for both Supply Corporation and
Empire. Supply Corporation transports and stores natural gas for utilities (including Distribution Corporation),
natural gas marketers (including NFR) and pipeline companies in the northeastern United States markets.
Empire transports natural gas from the United States/Canadian border near Buffalo, New York into Central New
York just north of Syracuse, New York. Empire’s new facilities (the Empire Connector project), which consists of
a compressor station and a pipeline extension from near Rochester, New York to an interconnection near
Corning, New York with the unaffiliated Millennium Pipeline, were placed into service on December 10, 2008.
Empire transports gas to major industrial companies, utilities (including Distribution Corporation) and power
producers.

The Exploration and Production segment, through Seneca, is engaged in exploration for, and development
and purchase of, natural gas and oil reserves in California, in the Appalachian region of the United States, and in
the Gulf Coast region of Texas and Louisiana. Seneca’s production is, for the most part, sold to purchasers
located in the vicinity of its wells. As disclosed in Note J — Discontinued Operations, on August 31, 2007,
Seneca completed the sale of SECI, its wholly owned subsidiary operating in Canada, for a gain of approximately
$120.3 million, net of tax, during the fourth quarter of 2007. As a result of the sale, SECI’s operations have been
reported as discontinued operations. As disclosed in Note M — Acquisition, on July 20, 2009, Seneca acquired
Ivanhoe Energy’s United States oil and gas operations for approximately $39.2 million (including cash
acquired). Ivanhoe Energy’s United States oil and gas operations were incorporated into the Company’s
consolidated financial statements for the period subsequent to the completion of the acquisition on July 20,
2009.

The Energy Marketing segment is comprised of NFR’s operations. 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 for its customers.

The data presented in the tables below reflect financial information for the segments and reconciliations to
consolidated amounts. The accounting policies of the segments are the same as those described in Note A —
Summary of Significant Accounting Policies. Sales of products or services between segments are billed at
regulated rates or at market rates, as applicable. The Company evaluates segment performance based on income
before discontinued operations, extraordinary items and cumulative effects of changes in accounting (when
applicable). When these items are not applicable, the Company evaluates performance based on net income.

Note L — Investments in Unconsolidated Subsidiaries

The Company’s unconsolidated subsidiaries consist of equity method investments in Seneca Energy, Model
City, ESNE and Whitetail Processing Plant. The Company has 50% interests in each of the first three entities and
a 35% ownership interest in the Whitetail Processing Plant. Seneca Energy and Model City generate and sell
electricity using methane gas obtained from landfills owned by outside parties. ESNE generates electricity from
an 80-megawatt, combined cycle, natural gas-fired power plant in North East, Pennsylvania. ESNE sells its
electricity into the New York power grid. Whitetail Processing Plant is currently under construction with
completion expected in the fall of 2009. Once completed, the plant will extract natural gas liquids from local
production in Pennsylvania.

During the quarter ended December 31, 2008, the Company recorded a pre-tax impairment of $1.8 million
($1.1 million on an after-tax basis) of its equity investment in ESNE due to a decline in the fair market value of
ESNE. The impairment was driven by a significant decrease in “run time” for the plant given the economic
downturn and the resulting decrease in demand for electric power.

A summary of the Company’s investments in unconsolidated subsidiaries at September 30, 2009 and 2008

is as follows:

Note M — Acquisition

On July 20, 2009, the Company’s wholly-owned subsidiary in the Exploration and Production segment,
Seneca, acquired all of the shares of Ivanhoe Energy’s United States oil and gas operations for approximately
$39.2 million in cash (including cash acquired), of which $2.0 million was held in escrow at September 30,
2009. In accordance with the purchase agreement, this amount will remain in escrow for one year from the
closing of the transaction provided there are no pending disputes or actions regarding obligations and liabilities
required to be satisfied or discharged by Ivanhoe Energy. Ivanhoe Energy’s United States oil and gas operations
were incorporated into the Company’s consolidated financial statements for the period subsequent to the
completion of the acquisition on July 20, 2009. As of the acquisition date, these assets produced approximately
645 (595 net) barrels per day of oil in California and Texas. The purchase also included certain exploration
acreage in California. This acquisition adds to the Company’s existing oil producing assets in the Midway Sunset
Field in California. The acquisition consisted of approximately $37.1 million in property, plant and equipment,

Note N — Intangible Assets

As a result of the Empire and Toro acquisitions in 2003, the Company acquired certain intangible assets. In
the case of the Empire acquisition, the intangible assets represent the fair value of various long-term trans-
portation contracts with Empire’s customers. In the case of the Toro acquisition, the intangible assets represent
the fair value of various long-term gas purchase contracts with the various landfills. These intangible assets are
being amortized over the lives of the transportation and gas purchase contracts with no residual value at the end
of the amortization period. The weighted-average amortization period for the gross carrying amount of the
transportation contracts is 8 years. The weighted-average amortization period for the gross carrying amount of
the gas purchase contracts is 20 years. Details of these intangible assets are as follows (in thousands):

In September 2009, the Company recorded a pre-tax impairment of $4.6 million in the value of certain
long-lived assets in the All Other category due to the loss of the primary customer at one of Toro’s landfill gas
sites and the anticipated shut-down of the site. The impairment was comprised of a $2.6 million reduction in
intangible assets related to long-term gas purchase contracts and a $2.0 million reduction in property, plant and
equipment. The $2.6 million intangible assets impairment was recorded to Purchased Gas expense and the
$2.0 million property, plant and equipment impairment was recorded to Depreciation, Depletion and Amor-
tization expense on the Consolidated Statement of Income. The $2.6 million impairment of the intangible asset
is included in amortization expense for the year ended September 30, 2009 in the table shown above.

In October 2008, the Company completed the amortization of intangible assets related to two long-term
transportation contracts. As such, the gross carrying amount of intangible assets subject to amortization was
reduced from $8.6 million at September 30, 2008 to $4.7 million at September 30, 2009. Accumulated
amortization was reduced by the same amount. Aside from this change, the only activity with regard to
intangible assets subject to amortization was amortization expense as shown in the table above. Amortization
expense for the long-term transportation contracts is estimated to be $0.4 million annually for 2010, 2011,

2012, 2013 and 2014. Amortization expense for the long-term gas purchase contracts is estimated to be
$1.4 million annually for 2010, 2011, 2012, 2013 and 2014.

Note O — Quarterly Financial Data (unaudited)

In the opinion of management, the following quarterly information includes all adjustments necessary for a
fair statement of the results of operations for such periods. Per common share amounts are calculated using the
weighted average number of shares outstanding during each quarter. The total of all quarters may differ from the
per common share amounts shown on the Consolidated Statements of Income. Those per common share
amounts are based on the weighted average number of shares outstanding for the entire fiscal year. Because of
the seasonal nature of the Company’s heating business, there are substantial variations in operations reported on
a quarterly basis.

Reserve Quantity Information

The Company’s proved oil and gas reserves are located in the United States. The estimated quantities of
proved reserves disclosed in the table below are based upon estimates by qualified Company geologists and
engineers and are audited by independent petroleum engineers. Such estimates are inherently imprecise and
may be subject to substantial revisions as a result of numerous factors including, but not limited to, additional
development activity, evolving production history and continual reassessment of the viability of production
under varying economic conditions.

(1) During 2009, the Company made a downward revision of its proved developed and undeveloped reserves
amounting to 9,589 MMcf. This was primarily attributable to a 19,484 MMcf reduction in the Appalachian

region offset by a 9,407 MMcf increase in the Gulf Coast region. The reduction in the Appalachian region
was mainly due to declining natural gas prices, which made certain reserves uneconomical. The improve-
ment in the Gulf Coast region was due to improved performance of Gulf Coast properties.

Standardized Measure of Discounted Future Net Cash Flows Relating to Proved Oil and Gas Reserves

The Company cautions that the following presentation of the standardized measure of discounted future
net cash flows is intended to be neither a measure of the fair market value of the Company’s oil and gas
properties, nor an estimate of the present value of actual future cash flows to be obtained as a result of their
development and production. It is based upon subjective estimates of proved reserves only and attributes no
value to categories of reserves other than proved reserves, such as probable or possible reserves, or to unproved
acreage. Furthermore, it is based on year-end prices and costs adjusted only for existing contractual changes,
and it assumes an arbitrary discount rate of 10%. Thus, it gives no effect to future price and cost changes certain
to occur under widely fluctuating political and economic conditions.

121

NATIONAL FUEL GAS COMPANY

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS — (Continued)

The standardized measure is intended instead to provide a means for comparing the value of the Company’s
proved reserves at a given time with those of other oil- and gas-producing companies than is provided by a
simple comparison of raw proved reserve quantities.

Item 9A Controls and Procedures

Evaluation of Disclosure Controls and Procedures

The term “disclosure controls and procedures” is defined in Rules 13a-15(e) and 15d-15(e) under the
Exchange Act. These rules refer to the controls and other procedures of a company that are designed to ensure
that information required to be disclosed by a company in the reports that it files or submits under the Exchange
Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and
forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to
ensure that information required to be disclosed is accumulated and communicated to the company’s man-
agement, including its principal executive and principal financial officers, as appropriate to allow timely
decisions regarding required disclosure. The Company’s management, including the Chief Executive Officer
and Principal Financial Officer, evaluated the effectiveness of the Company’s disclosure controls and procedures
as of the end of the period covered by this report. Based upon that evaluation, the Company’s Chief Executive
Officer and Principal Financial Officer concluded that the Company’s disclosure controls and procedures were
effective as of September 30, 2009.

Management’s Annual Report on Internal Control over Financial Reporting

The management of the Company is responsible for establishing and maintaining adequate internal control
over financial reporting as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act. The Company’s
internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of
financial reporting and preparation of financial statements for external purposes in accordance with GAAP.
Because of its inherent limitations, internal control over financial reporting may not prevent or detect
misstatements.

The Company’s management assessed the effectiveness of the Company’s internal control over financial
reporting as of September 30, 2009. In making this assessment, management used the framework and criteria set
forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal
Control — Integrated Framework. Based on this assessment, management concluded that the Company main-
tained effective internal control over financial reporting as of September 30, 2009.

PricewaterhouseCoopers LLP, the independent registered public accounting firm that audited the Com-
pany’s consolidated financial statements included in this Annual Report on Form 10-K, has issued an attestation
report on the effectiveness of the Company’s internal control over financial reporting as of September 30, 2009.
The report appears in Part II, Item 8 of this Annual Report on Form 10-K.

Changes in Internal Control over Financial Reporting

There were no changes in the Company’s internal control over financial reporting that occurred during the
quarter ended September 30, 2009 that have materially affected, or are reasonably likely to materially affect, the
Company’s internal control over financial reporting.

This Annual Report contains “forward-looking statements” as defined by the Private Securities Litigation Reform Act of 1995. Forward-looking statements should 
be read with the cautionary statements and important factors included in the Company’s Form 10-K at Item 7, MD&A, under the heading “Safe Harbor for Forward-
Looking Statements.” Forward-looking statements are all statements other than statements of historical fact, including, without limitation, statements regarding 
future prospects, plans, objectives, goals, projections, strategies, future events or performance and underlying assumptions, capital structure, anticipated capital 
expenditures, completion of construction and other projects, projections for pension and other post-retirement benefit obligations, impacts of the adoption of 
new accounting rules, and possible outcomes of litigation or regulatory proceedings, as well as statements that are identified by the use of the words “anticipates,” 
“estimates,” “expects,” “forecasts,” “intends,” “plans,” “predicts,” “projects,” “believes,” “seeks,” “will,” “may” and similar expressions.

The Securities and Exchange Commission (the “SEC”) currently permits the Company, in its filings with the SEC, to disclose only proved reserves that the Company 
has demonstrated by actual production or conclusive formation tests to be economically and legally producible under existing economic and operating conditions. 
The Company uses the terms “probable,” “possible,” “resource potential” and other descriptions of volumes of reserves or resources potentially recoverable through 
additional drilling or recovery techniques that the SEC’s guidelines would prohibit us from including in filings with the SEC. These estimates are by their nature more 
speculative than estimates of proved reserves and, accordingly, are subject to substantially greater risk of being actually realized. Investors are urged to consider 
closely the disclosure in our Form 10-K.

This Annual Report and the statements contained herein are submitted for the general information of stockholders and employees of the Company and are 
not intended to induce any sale or purchase of securities or to be used in connection therewith. For up-to-date information, we have two sources for your use.
