PART I

Item 1. Business.

General

     EnergySouth, Inc. (together with its subsidiaries, the “Company” or “Registrant”, and exclusive of its subsidiaries, “EnergySouth”) was initially incorporated under the laws of the State of Alabama on September 5, 1997 for the primary purpose of becoming the holding company for Mobile Gas Service Corporation (“Mobile Gas”), a natural gas utility, and its subsidiaries. Effective February 2, 1998, Mobile Gas and its subsidiaries were reorganized (the “Reorganization”) into a holding company structure whereby Mobile Gas became a wholly-owned subsidiary of EnergySouth.

     Mobile Gas was incorporated under the laws of the State of Alabama in 1933. Mobile Gas is engaged in the purchase, distribution, sale and transportation of natural gas to approximately 98,000 residential, commercial and industrial customers in Southwest Alabama, including the City of Mobile. Mobile Gas’ service territory covers approximately 300 square miles. Mobile Gas is also involved in merchandise sales, specifically sales of natural gas appliances.

     EnergySouth Services, Inc. (“Services”) was incorporated in March 1983. Through Services, the Company provides contract and consulting work for utilities and industrial customers. Services owns a 51% interest in Southern Gas Transmission Company (“SGT”), an Alabama general partnership which was formed in November 1991. SGT was established to provide transportation services to the facilities of Alabama River Pulp Company, Inc (“ARP”). During fiscal year 1992, SGT constructed and began operating a 50-mile pipeline from the facilities of Gulf South Pipeline Company (“Gulf South”) near Flomaton, Alabama to the facilities of ARP in Claiborne, Alabama.

     MGS Marketing Services, Inc. (“Marketing”) was incorporated on March 5, 1993 to assist existing and potential customers in the purchase of natural gas. During fiscal year 2003, as existing contracts for marketing services expired, such contracts were not renewed by Marketing. As of September 30, 2003 and 2004, the Company was not actively engaged in activities previously provided by Marketing.

     In connection with the Reorganization, Services and Marketing became wholly-owned subsidiaries of EnergySouth during fiscal year 1998.

     MGS Storage Services, Inc. (“Storage”) was incorporated on December 4, 1991 as a wholly-owned subsidiary of Mobile Gas. Effective December 19, 2000, Storage became a wholly-owned subsidiary of EnergySouth. As of September 30, 2004 Storage held a general partnership interest of 90.9% in Bay Gas Storage Company, Ltd. (“Bay Gas”), an Alabama limited partnership, and a 9.1% limited partnership interest was held by Olin Corporation (“Olin”). Bay Gas owns and operates underground gas storage and related pipeline facilities which are used to provide storage and delivery of natural gas for Mobile Gas and other customers.

Business Segments

          The Company’s operations are classified into the following business segments:

•

Natural Gas Distribution – The Natural Gas Distribution segment is actively engaged in the distribution and transportation of natural gas to residential, commercial and industrial customers in Southwest Alabama through Mobile Gas and SGT.

•

Natural Gas Storage – The Natural Gas Storage segment provides for the underground storage of natural gas and transportation services through the operations of Bay Gas and Storage. The storage operations are located in Southwest Alabama.

•

Other – Includes merchandising, financing, and other energy-related services which are provided through Mobile Gas, and Services, respectively, and are aggregated with the corporate operations of EnergySouth, the holding company.

          For financial information by business segment, including revenues by segment, for the fiscal years ended September 30, 2004, 2003, and 2002, see Note 10 to the Consolidated Financial Statements.

Customers

          Of the approximately 98,000 customers of the Company, approximately 95% are residential customers. In the fiscal year ended September 30, 2004, approximately 58% of the Company’s gas revenues were derived from residential sales, 15% from small commercial and industrial sales, 8% from large commercial and industrial sales, 9% from transportation services, and 10% from storage and miscellaneous services. Residential sales in fiscal 2004 accounted for approximately 6% of the total volume of gas delivered to the Company’s customers, with small commercial and industrial, large commercial and industrial, and transportation deliveries accounting for approximately 2%, 1% and 91%, respectively. The ten largest customers of the Company accounted for approximately 23% of the Company’s gross margin in fiscal 2004, with the largest accounting for approximately 9%. (Gross margin refers to Gas Revenue less Cost of Gas, as shown on the Consolidated Statements of Income on page F-3.) For further information with respect to revenues from and deliveries to the various categories of the Company’s customers, see Item 6, “Selected Financial Data” below. Gross margins by business segment are shown in Note 10 of the Notes to the Consolidated Financial Statements on page F-26.

          EnergySouth is located at the crossroads of the expanding offshore natural gas production areas of the Central Gulf Coast and the developing gas-fired electric generation markets in the lower Southeast region of the United States. Mobile Gas provides transportation services to two electric generating facilities which became operational in fiscal 2001. Bay Gas provides transportation services to three gas-fired electric generating facilities. During fiscal 1999 Bay Gas entered into storage contracts with electric utilities which fully subscribed the remaining space in its first storage cavern. During fiscal 2000 Bay Gas entered into a long term contract with Southern Company Services, Inc., as agent for a number of electric utility subsidiaries of Southern Company, to provide storage capacity of up to 3.2 million MMBtu of natural gas for those subsidiaries. To accommodate this contract, Bay Gas constructed a second underground storage cavern as discussed in “Gas Storage” below. While there are no current reported plans

2

for additional gas-fired electric generation facilities in the Company’s immediate service area, industry projections indicate Florida utilities plan to add gas fueled power generation in the next decade. Management believes that Bay Gas, with the possible construction of additional caverns, is well positioned to serve the storage needs of that market. During fiscal 2004, Bay Gas concluded a non-binding “open season” to assess interest for up to 5.0 Bcf of additional working gas capacity. Bay Gas is currently following up with the respondents in an effort to secure agreements for firm storage services. There can be no assurances that additional caverns will be constructed.

Gas Supply

     The Company is directly connected to four natural gas processing plants in south Mobile County. Mobile Gas has contracted for a portion of its firm supply directly with two of these producers. For the fiscal year ended September 30, 2004, the Company obtained approximately 54% of its gas supply from sources located in the Mobile Bay area, with the balance being obtained from interstate sources.

     Mobile Gas has a current peak day firm requirement of 117,000 MMBtus. Firm supply needs of 80,000 MMBtu/day are expected to be met through the withdrawal of gas from the storage facility owned by Bay Gas. The Company also had firm supply contracts with gas suppliers for peak day needs of 13,000 MMBtu/day through October 31, 2004. The Company has contracted for firm transportation and storage service (“No-Notice Service”) for 24,000 MMBtu/day from Gulf South under an agreement effective through March 31, 2011. Gas supply for “No-Notice Service” is met through a contract with BP Energy Company through March 31, 2005. The Company also has firm supply contracts with Coral Energy for varying monthly quantities through March 31, 2005 through the direct connection with the Shell Yellowhammer processing plant.

Gas Storage

     Construction of Bay Gas’ first storage cavern and facilities was completed in 1994. At September 30, 2004, the cavern had the capacity to hold up to 3.2 million MMBtu of natural gas. Approximately .9 million MMBtu of the gas injected into the storage cavern, called “base gas,” remains in the cavern to provide sufficient pressure to maintain cavern integrity, and the remainder, approximately 2.3 million MMBtu, represents working storage capacity. In 1994 Mobile Gas entered into a gas storage agreement with Bay Gas under which Bay Gas agreed to provide storage of .8 million MMBtu of working storage capacity of the first cavern for an initial period of 20 years.

     The construction of natural gas-fired electric generation facilities in the Southeast has provided opportunities to provide gas storage and transportation services. Construction of Bay Gas’ second storage cavern was completed and the cavern was placed into service April 1, 2003. Bay Gas entered into a fifteen-year contract with Southern Company Services, Inc. (Southern), an affiliate of Southern Company, for most of the second cavern capacity. During fiscal year 2004, the remaining capacity of the second cavern was fully subscribed on a firm basis. Currently, the second storage cavern has a working capacity of 3.7 Bcf. Together, the two caverns at Bay Gas currently hold 6.0 Bcf, with injection and withdrawal capacity of 200 MMcf and 610 MMcf per day, respectively, but the two existing storage caverns are currently planned to ultimately hold 7.0 Bcf, with injection and withdrawal capacity of 300 MMcf and 700 MMcf per day, respectively. The additional development of the existing storage caverns is currently projected to continue through fiscal 2007 without interruption of storage operations. Bay Gas has pipeline interconnects with Florida Gas Transmission Company and Gulf South which provide access to interstate markets.

Competition

     Gas Distribution Competition. The Company is not in significant direct competition with respect to the retail distribution of natural gas to residential, small commercial and small industrial customers within its service area. Electricity competes with natural gas for such uses as cooking, water heating and space heating.

     The Company’s large commercial and industrial customers with requirements of 200 MMBtu per day or more have the right to contract with the Company to transport customer-owned gas while other commercial and industrial customers buy natural gas from the Company. Some industrial customers have the capability to use either fuel oil, coal, wood chips or natural gas, and choose their fuel depending upon a number of factors, including the availability and price of such fuels. In recent years, the Company has had adequate supplies so that interruptible industrial customers that are capable of using alternative fuels have not had supplies curtailed. The Company’s rate tariffs include a competitive fuel clause which allows the Company to adjust its rates to certain large commercial and industrial customers in order to compete with alternative energy sources. Even so, in recent periods of volatility in natural gas prices, several customers who have the capability to use alternative fuels have switched to such alternative fuel sources in periods of extremely high natural gas prices. See “Rates and Regulation” below.

     Due to the close proximity of various pipelines and gas processing plants to the Company’s service area, there exists the possibility that current or prospective customers could install their own facilities and connect directly to a supply source and thereby “bypass” the Company’s service. The Company believes that because it has worked closely with major industrial customers to meet those customers’ needs, and because of its ability to provide competitive pricing under its rate tariffs, none of the Company’s customers have bypassed its facilities to date. Although there can be no assurance as to future developments, the Company intends to continue its efforts to reduce the likelihood of bypass by offering competitive rates and services to such customers.

     Gas Storage Competition. A number of types of competitors may provide services like or in competition with those of Bay Gas. These include, among others, natural gas storage facilities, natural gas aggregators, and natural gas pipelines. Bay Gas believes that its strategic geographic location and its ability to charge market-based rates for interstate storage services will enable it to effectively compete with such competitors. See “Rates and Regulation” below.

Rates and Regulation

     The natural gas distribution operations of Mobile Gas are under the jurisdiction of the Alabama Public Service Commission (“APSC”). The APSC approves rates which are intended to permit the recovery of the cost of service including a return on investment. Rates have historically been determined by reference to rate tariffs approved by the APSC in traditional rate proceedings or, for certain large customers, on a case-by-case basis. In addition, pursuant to APSC order, rates for a limited number of large industrial customers are determined on a privately negotiated basis. Since December 1, 1995, Mobile Gas has also been allowed to recover costs associated with its replacement of cast iron mains. This component of rates is adjusted annually through a filing with the APSC. The rates for service rendered by Mobile Gas are on file with the APSC. The APSC also approves the issuance of debt and equity securities and has supervision and regulatory authority over service, pipeline safety, accounting, and other matters.

     On June 10, 2002, the APSC approved Mobile Gas’ request for the Rate Stabilization and Equalization (“RSE”) rate setting process to be effective October 1, 2002 through September 30, 2005, and thereafter, unless modified or discontinued by APSC order. Under RSE, the APSC conducts quarterly reviews to determine, based on Mobile Gas’ projections and fiscal year-to-date performance, whether Mobile Gas’ return on equity is expected to be within the allowed range of 13.35% to 13.85%. Reductions in rates can be made quarterly to bring the projected return within allowed range; increases, however, are allowed only once each fiscal year, effective December 1, and cannot exceed four percent of prior-year revenues. RSE limits the amount of Mobile Gas’ equity upon which a return is permitted to 60 percent of its total capitalization and provides for certain cost control measures designed to monitor Mobile Gas’ operations and maintenance (“O&M”) expense. Under the inflation-based cost control measurement established by the APSC, if a change in Mobile Gas’ O&M expense per customer falls within 1.5 percentage points above or below the change in the Consumer Price Index for All Urban Customers (index range), no adjustment is required. If the change in O&M expense per customer exceeds the index range, three-quarters of the difference is returned to customers. To the extent the change is less than the index range, the utility benefits by one-half of the difference through future rate adjustments. A rate adjustment designed to increase annual revenues by $2.2 million became effective December 1, 2002 under RSE. Effective December 1, 2003, rates were adjusted under RSE which were designed to increase annual revenues by $2.8 million, resulting in a return on equity that exceeded the allowed range in fiscal 2004. An adjustment of $343,000 was made to fiscal year 2004 earnings such that the return on equity as calculated for RSE purposes equals 13.6%, the midpoint of the allowed range, and a regulatory liability was recorded which reflects the amount owed to customers. A corresponding reduction in rates will be made in fiscal year 2005.

     In conjunction with the approval of RSE, the APSC approved an Enhanced Stability Reserve (“ESR”), beginning October 1, 2002, to which Mobile Gas may charge the full amount of: 1) extraordinary O&M expenses resulting from force majeure events such as storms, severe weather, and outages, when one such event results in more than $100,000 of additional O&M expense or a combination of two or more such events results in more than $150,000 of additional O&M expense during a fiscal year; or 2) losses of revenue from any individual industrial or commercial customer in excess of $100,000 during the fiscal year, if such losses cause Mobile Gas’ return on equity to fall below 13.35%. An initial ESR balance

5

of $1.0 million was recorded October 1, 2002 and is being recovered from customers through rates beginning October 1, 2002. Subject to APSC approval, additional funding, up to a maximum reserve balance of $1.5 million, may be provided by any future non-recurring revenue should such revenue cause Mobile Gas’ return on equity for the fiscal year to exceed 13.85%. During the year ended September 30, 2003, Mobile Gas charged $146,000 against the ESR related to revenue losses from a certain large industrial customer. Following a year in which a charge against the ESR is made, the APSC allows for accruals to the ESR of no more than $15,000 monthly until the maximum funding level is achieved; however, no such accruals have been made during the year ended September 30, 2004..

     Mobile Gas is also authorized by the APSC to apply a temperature rate adjustment to customers’ gas bills for the months of November through April. The temperature rate adjustment helps to level out the effects of temperature extremes on Company earnings by reducing high gas bills to customers in colder than normal weather and increasing gas revenues received by the Company in warmer than normal weather. The temperature rate adjustment has been reflected in customers’ gas bills during the months of November through April since November 1, 1996.

     The Mobile Gas tariffs include a purchased gas adjustment clause which allows it to pass on to its sales customers increases or decreases in gas costs from those reflected in its tariff charges. Adjustments under such clauses require periodic filings with the APSC but do not require a general rate proceeding. Under the purchased gas adjustment clause, Mobile Gas has a competitive fuel clause which gives it the right to adjust its rates to certain large customers in order to compete with alternative energy sources. Any margin lost as a result of competitive fuel clause adjustments is recoverable from its other customers.

     Gas deliveries to certain industrial customers are subject to regulation by the APSC through contract approval. The operations of SGT, which consist only of intrastate transportation of gas, are also regulated by the APSC.

     Bay Gas is a regulated utility governed under the jurisdiction of the APSC. As a regulated utility, Bay Gas’ intrastate storage contracts are subject to APSC approval. Operation of the storage cavern and well-head equipment are subject to regulation by the Oil and Gas Board of the State of Alabama. The APSC certificated Bay Gas as an Alabama gas storage public utility in 1992. Bay Gas provides substantial, long-term services for Mobile Gas and other customers that include storage and transportation of natural gas from interstate and intrastate sources. The APSC does not regulate rates for Bay Gas interstate gas storage and storage-related services. The Federal Energy Regulatory Commission (FERC), which has jurisdiction over interstate services, allows Bay Gas to charge market-based rates for such services. Market-based rates minimize regulatory involvement in the setting of rates for storage services and allow Bay Gas to respond to market conditions. Bay Gas also provides interstate transportation-only services. The FERC last issued orders on October 11, 2001 and June 3, 2002 approving rates for such services. On March 9, 2004, in accordance with FERC filing requirements, Bay Gas filed a petition with the FERC requesting approval of new rates for transportation-only service.

     Mobile Gas has been granted nonexclusive franchises to construct, maintain and operate a natural gas distribution system in the areas in which it operates. Except for the franchise granted by Mobile County, Alabama, which has no stated expiration date, the franchises have

6

various expiration dates, the earliest of which is in 2007. The Company has no reason to believe that the franchises will not be renewed upon expiration.

Seasonal Nature of Business

     The nature of the Company’s business is highly seasonal and temperature-sensitive. As a result, the Company’s operating results in any given period have historically reflected, in addition to other matters, the impact of weather, with colder temperatures resulting in increased sales by the Company. The substantial impact of this sensitivity to seasonal conditions has been reflected in the Company’s results of operations. As discussed above under “Rates and Regulation”, the application of a temperature rate adjustment in customers’ bills beginning in November 1996 has helped to level out the effects of temperature extremes on results of operations.

     Due to the seasonality of the Company’s business, the generation of working capital is impaired during the summer months because of reduced gas sales. Cash needs during this period are met generally through short-term financing arrangements or the reduction of temporary investments as is common in the industry.

Environmental Issues

     The Company is subject to various federal, state and local laws and regulations relating to the environment, which have not had a material effect on the Company’s financial position or results of operations.

     Like many gas distribution companies, prior to the widespread availability of natural gas, the Company manufactured gas for sale to its customers. In contrast to some other companies which operated multiple manufactured gas plants, the Company and its predecessor operated only one such plant, which discontinued operations in 1933. The process for manufacturing gas produced by-products and residuals, such as coal tar, and certain remnants of these residuals are sometimes found at former gas manufacturing sites.

     Based on recent plans for the Company’s former gas plant site, the Alabama Department of Environmental Management (“ADEM”) is conducting a “Brownfields” evaluation of the property. Testing of the site has been completed by ADEM; however, the Company is unable to predict when ADEM’s final report will be available. The Company engaged environmental consultants to evaluate the site in connection with the plans for the site. Based on their review, the Company has recorded its best estimate of $200,000 as an expense and a remediation liability in fiscal 2004. The APSC has concurred with this treatment. However, should further investigation or changes in environmental laws or regulations require material expenditures for evaluation or remediation with regard to the site, the Company would apply to the APSC for appropriate rate recovery of such costs. However, there can be no assurances that the APSC would approve the recovery of such costs or the amount and timing of any such recovery.

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

The Company

EnergySouth, Inc. (EnergySouth) is a holding company for a family of energy businesses. EnergySouth and its consolidated subsidiaries are collectively referred to herein as the “Company.” The Company, through Mobile Gas Service Corporation (Mobile Gas) and Southern Gas Transmission Company (SGT), is engaged in the distribution of natural gas to residential, commercial and industrial customers in southwest Alabama. Through Bay Gas Storage Company, Ltd. (Bay Gas), the Company provides underground natural gas storage services and transportation services. Other EnergySouth subsidiaries are engaged in merchandising, financing, and other energy-related services.

Summary

Consolidated Net Income

Diluted earnings per share increased $0.15, up 10% from fiscal 2003. Fiscal year 2003 earnings per share increased 7% as compared to fiscal 2002. Financial information by business segment is shown in Note 10 to the Consolidated Financial Statements.

2004 vs 2003 Earnings from the Company’s natural gas distribution business increased $0.09 per diluted share during fiscal year 2004, primarily from its Mobile Gas subsidiary. Mobile Gas’ earnings were positively impacted by rate adjustments which became effective December 1, 2003 and 2002 based upon the guidelines established under the Rate Stabilization and Equalization (RSE) tariff. For further information on RSE, see “Natural Gas Distribution” below and Note 2 to the Consolidated Financial Statements. Earnings were also positively impacted by an increase in temperature-sensitive customers’ gas consumption, when adjusted for weather, during the winter heating season of fiscal year 2004. These increases were partially offset by an increase in operating and depreciation expenses and a decline in volumes delivered to industrial customers.

The Company’s natural gas storage business, operated by Bay Gas, contributed increased earnings of $0.07 per diluted share during fiscal 2004. This positive earnings contribution was due primarily to increased storage revenues from its second storage cavern which was placed in service on April 1, 2003. The increased revenues were partially offset by additional operations and maintenance costs, depreciation expense and property taxes due to the completion of the second storage cavern.

Earnings from other business operations decreased $0.01 per diluted share during fiscal 2004 due primarily to a decrease in interest income from financing activities, additional provisions for bad debts and increased operating expenses related to merchandise sales.

2003 vs 2002 For fiscal year 2003, EnergySouth’s earnings per diluted share increased $.10 from fiscal year 2002 due to increased earnings in all business segments. The Company’s natural gas distribution business contributed increased earnings of $0.02 per

16

diluted share due to a rate adjustment which became effective December 1, 2002 based upon the guidelines established under the RSE tariff. Because of the rate adjustment, margins from temperature-sensitive customers and large commercial and industrial customers increased during fiscal year 2003; however, these increases were offset by lower industrial transportation revenues and a decline in residential usage as adjusted for weather. The Company’s natural gas storage business contributed increased earnings of $0.04 per diluted share due primarily to increased storage revenues realized from its second storage cavern, placed in service on April 1, 2003, and revenues realized from short-term interruptible storage contracts. Increased depreciation expense and operating expenses partially offset the increased earnings for both the distribution and storage businesses. Earnings per diluted share from other business operations increased $0.04 during fiscal year 2003, which did not include losses incurred in 2002 associated with the exit from the natural gas generator sales business and the closing of a retail specialty store.

Results Of Operations

Natural Gas Distribution

The natural gas distribution segment of the Company is actively engaged in the distribution and transportation of natural gas to residential, commercial and industrial customers in southwest Alabama through Mobile Gas and SGT.

The Alabama Public Service Commission (APSC) regulates the Company’s gas distribution operations. Mobile Gas’ rate tariffs for gas distribution allow rate adjustments to pass through to customers the cost of gas, certain taxes, and incremental costs associated with the replacement of cast iron mains. These costs, therefore, have little direct impact on the Company’s unit margins, which are defined as natural gas distribution revenues less the cost of natural gas and related taxes. For fiscal year 2003, colder than normal weather during the 2002-2003 winter heating season, lower national storage levels after the 2002-2003 winter, and increased natural gas electric generation facilities combined to drive natural gas prices to levels well above historical norms. During fiscal year 2004, natural gas prices have continued to increase. Should gas prices rise to exceptional levels or continue to remain at high levels for an extended period of time, the Company’s margins, in aggregate dollars, could be negatively impacted by changes in customers’ behavior through 1) energy conservation efforts that reduce consumption or 2) converting from natural gas to an alternative heating source. Since the winter of 2000-2001, when the commodity price of natural gas first rose to unprecedented levels, Mobile Gas has experienced negative net growth in customers served. Customer counts as of the end of the fiscal year declined approximately 1.4% in fiscal 2004 and 0.3% in fiscal 2003. While Mobile Gas continues to expand its service territory by adding new mains and services, these additions have been more than offset by the number of customers who have left our system. Mobile Gas is focused on improving net customer growth through strategies that are directed at 1) increasing appliances in new and existing customers’ homes, 2) seeking high-value commercial customers that use natural gas for purposes other than space heating, 3) retaining customers by marketing the benefits of gas appliances and identifying and targeting those customers who may be at risk for leaving our system or converting to alternative fuels, and 4) minimizing the volatility of natural gas prices in customers’ bills.

Mobile Gas follows a gas purchasing strategy to secure prices for a portion of its gas supply needs for the winter heating season by locking in gas prices at fixed rates. Mobile Gas’ strategy for purchasing gas and the Company’s use of natural gas storage capacity help to mitigate the impact of increased prices on customers’ bills. However, effective June 1, 2004 and March 1, 2003, Mobile Gas adjusted its rates to reflect the increased gas costs paid to its suppliers.

In fiscal year 2002, the APSC approved Mobile Gas’ request for an RSE tariff, a ratemaking methodology already used by the APSC to regulate certain other utilities. Rate adjustments, designed to increase annual gas revenues by approximately $2.8 million and $2.2 million, were implemented under the RSE tariff effective December 1, 2003 and 2002, respectively. Increases are allowed only once each fiscal year, effective December 1, and cannot exceed four percent of prior-year revenues. Under RSE, the APSC has conducted reviews using fiscal year-to-date performance through January, April and July plus Mobile Gas’ budget projections to determine whether Mobile Gas’ return on equity was expected to be within the allowed range of 13.35% to 13.85% at the end of the fiscal year. No such adjustments were required through the July 2004 test period. Mobile Gas’ financial results for fiscal year 2004 did, however, result in a return on equity above the allowed range. As a result, an adjustment of $343,000 was made to fiscal year 2004 earnings such that the return on average equity as calculated for RSE purposes equals 13.6%, the midpoint of the allowed range, and a regulatory liability in that amount was recorded which reflects the amount owed to customers. A corresponding reduction in rates will be made in fiscal year 2005. See Notes 1 and 2 to the Consolidated Financial Statements.

The Company’s distribution business is highly seasonal and temperature-sensitive since residential and commercial customers use more gas during colder weather for space heating. As a result, gas revenues, cost of gas and related taxes in any given period reflect, in addition to other factors, the impact of weather, through either increased or decreased sales volumes. The Company utilizes a temperature rate adjustment rider during the months of November through April to mitigate the impact that unusually cold or warm weather has on operating margins by reducing the base rate portion of customers’ bills in colder than normal weather and increasing the base rate portion of customers’ bills in warmer than normal weather. Normal weather for the Company’s service territory is defined as the 30-year average temperature as determined by the National Weather Service.

Natural gas distribution revenues increased $13,120,000 (15%) and $10,500,000 (14%), respectively, during fiscal 2004 and 2003 due primarily to the rate adjustments to recover increased gas costs paid to suppliers. Revenues also increased during the current year periods as a result of the RSE rate adjustments which went into effect on December 1, 2003 and 2002.

Revenues from the sale of natural gas to residential and small commercial customers, referred to as temperature-sensitive customers since their gas usage is affected to a large degree by temperatures during the heating season, increased $13,119,000 (19%) and $9,311,000 (16%), respectively, during fiscal 2004 and 2003 due to the rate adjustments discussed above. During fiscal 2004, the increase in revenues from rate adjustments was partially offset by a decline in customers served and the impact of weather. Temperatures during the fiscal 2004 winter heating season were 2% warmer than normal and 9% warmer that the prior year. As a result, volumes delivered to temperature-sensitive customers

18

declined 4% in fiscal 2004 when compared to fiscal 2003. Temperatures during the fiscal 2003 heating season were 8% colder than normal and 12% colder than fiscal 2002, which partially accounted for a 5% increase in volumes delivered to these customers.

Revenues from the sale of natural gas to large commercial and industrial customers increased 7% and 26% during fiscal 2004 and 2003, respectively, due to increases in the price of natural gas and the RSE adjustments. Volumes delivered to these customers declined 15% and 2%, respectively, for fiscal years 2004 and 2003 due primarily to the higher natural gas prices.

Revenues from the transportation of natural gas to commercial and industrial customers by the distribution business decreased $417,000 (6%) and $487,000 (6%), respectively, for fiscal 2004 and 2003 with a corresponding decline in volumes of 8% and 25%, respectively, due primarily to increased gas prices and general economic conditions. Mobile Gas’ service territory has experienced the effects of plant closings during the last three years. In addition to two customers’ previous plant closings in fiscal year 2001, a chemical company which is a customer of the Company ceased operations of its Mobile plant in June 2003, and some other industrial plants have decreased production or switched to alternative fuels. As permitted by the APSC, the lost margins in fiscal 2003 associated with the closure of the chemical plant were charged to the Enhanced Stability Reserve (ESR) with a corresponding offset to transportation revenue. Lost margins subsequent to fiscal 2003, as well as other changes affecting net income, were reflected in the RSE adjustment on December 1, 2003. See Note 2 to the Consolidated Financial Statements for information pertaining to ESR and RSE.

The cost of natural gas increased $10,532,000 (30%) and $8,601,000 (33%), respectively, for fiscal years 2004 and 2003. Natural gas distribution margins increased 5% and 3% for fiscal years 2004 and 2003, respectively, primarily as a result of the RSE rate adjustments. The increases in margin from rate adjustments in both years were partially offset by the decrease in volumes transported to industrial customers and a decline in the number of residential customers served. Even though volumes delivered to residential customers decreased in fiscal 2004 and increased in fiscal 2003 as a result of warmer and colder weather conditions, respectively, Mobile Gas’ temperature adjustment rider mitigates the impact on margins of weather that is warmer or colder than normal winter weather. In recent years, Mobile Gas has experienced declines in consumption from its’ residential customers, when adjusted for the impact of warmer or colder weather, as these customers replace old appliances with new, more energy efficient models and as new, more energy efficient homes are built. In more recent years, Management believes that some of this decline has been attributable to the high bills customers have received due to the high natural gas prices and colder weather conditions. This was the case in fiscal 2003 as customer consumption, when adjusted to take out usage related to colder than normal weather, declined 2.2%. Although this decline in weather adjusted usage has been the overall trend, usages per degree-day can and do vary between periods due to several factors including humidity, wind speed, cloud cover, and duration of cold spells. Contrary to the general trend, consumption by residential customers in fiscal 2004, when adjusted for weather, trended up from prior periods, increasing 1.3% from fiscal 2003. The increase in fiscal 2004 margins was partially offset by the declines in volumes delivered to large commercial and industrial customers who are not subject to the temperature adjustment rider.

19

Operations and maintenance (O&M) expenses increased $285,000 (1%) during fiscal 2004. O&M expenses for bad debt provisions increased $299,000 as compared to fiscal 2003 due to a rise in gas revenues associated with the increase in natural gas prices discussed above. Mobile Gas’ O&M expenses also reflect increases in insurance, employee benefit costs and an unusually high level of repairs and maintenance on mains. As discussed in Note 8 to the Consolidated Financial Statements, Mobile Gas also recorded a $200,000 remediation liability related to a manufactured gas plant. These increased expenses were partially offset by a decrease in payroll costs and associated benefits related to the elimination of sixteen positions during fiscal 2004 and a decrease in advertising and promotional expenses.

O&M expenses increased $534,000 (3%) for fiscal 2003 due to increases in insurance expense, advertising and promotional payments, payroll, postage and expenses related to the establishment of the ESR reserve. The change in Mobile Gas’ O&M expense per customer for fiscal 2004 and 2003 was within the inflation-based cost control range established by the APSC for RSE purposes; therefore, no adjustment is required as described in Note 2 to the Consolidated Financial Statements.

Depreciation expense increased $351,000 (5%) and $377,000 (6%), respectively, for fiscal 2004 and 2003 due to Mobile Gas’ capital expansion projects and increased investment in property, plant and equipment.

Other taxes primarily consist of property taxes and business license taxes that are based on gross revenues and fluctuate accordingly. Other taxes increased $723,000 and $651,000, respectively, for fiscal year 2004 and 2003 due primarily to the increased gas revenues discussed above.

Interest expense decreased $219,000 and $208,000, respectively, for fiscal 2004 and 2003 due to principal payments on long-term debt.

Natural Gas Storage

The natural gas storage segment provides for the underground storage of natural gas and transportation services through the operations of Bay Gas. The APSC certificated Bay Gas as an Alabama gas storage public utility in 1992. Through its first storage cavern with 2.3 Bcf of working gas capacity and connected pipeline, Bay Gas thereafter began providing substantial, long-term services for Mobile Gas and other customers that include storage and transportation of natural gas from interstate and intrastate sources. The APSC does not regulate rates for Bay Gas’ interstate gas storage and storage-related services. The Federal Energy Regulatory Commission (FERC), which has jurisdiction over interstate services, allows Bay Gas to charge market-based rates for such services. Market-based rates minimize regulatory involvement in the setting of rates for storage services and allow Bay Gas to respond to market conditions. Bay Gas also provides interstate transportation-only firm and interruptible services. The FERC last issued orders on October 11, 2001 and June 3, 2002 approving rates for such services. On March 9, 2004, in accordance with FERC filing requirements, Bay Gas filed a petition with the FERC requesting approval of new rates for transportation-only service.

20

The construction of natural gas-fired electric generation facilities in the Southeast has provided opportunities to provide gas storage and transportation services. Construction of Bay Gas’ second storage cavern was completed and the cavern was placed into service April 1, 2003. Bay Gas entered into a fifteen-year contract with Southern Company Services, Inc. (Southern), an affiliate of Southern Company, for most of the second cavern capacity. During fiscal year 2004, the remaining capacity of the second cavern was fully subscribed on a firm basis. Currently, the second storage cavern has a working capacity of 3.7 Bcf. Together, the two caverns at Bay Gas currently hold 6.0 Bcf, with injection and withdrawal capacity of 200 MMcf and 610 MMcf per day, respectively, but are currently planned to ultimately hold 7.0 Bcf, with injection and withdrawal capacity of 300 MMcf and 700 MMcf per day, respectively. The additional cavern development is projected to continue through fiscal 2007 without interruption of storage operations.

With the current working capacity of both caverns fully subscribed, Bay Gas recently began a process that could lead to additional cavern development. During fiscal 2004, Bay Gas concluded a non-binding “open season” to assess interest for up to 5.0 Bcf of additional working gas capacity. Bay Gas is currently following up with the respondents in an effort to secure agreements for firm storage services. Bay Gas plans to move forward with development of a third storage cavern subject to its ability to execute sufficient firm storage agreements with the interested parties.

Bay Gas’ revenues increased $3,177,000 (22%) and $3,074,000 (27%) during fiscal 2004 and 2003, respectively. See Note 10 to the Consolidated Financial Statements for segment disclosure. Revenues for both years were positively impacted by additional storage revenues associated with the commencement of operations of the second cavern. Fiscal 2004 revenues were also increased due to a new storage agreement which was signed during the first quarter of fiscal year 2004. Storage revenues for both years were partially offset by the expiration in May 2003 of an option agreement for transportation services over and above contracted volumes. Bay Gas entered into an agreement in November 2001 which granted to a customer an option to order transportation of additional volumes in excess of the volumes currently under long-term contract. Bay Gas received $3,274,000 in consideration of the option agreement which was amortized over the nineteen-month option period.

Operations and maintenance (O&M) expenses increased $401,000 (16%) and $513,000 (25%) during fiscal 2004 and 2003, respectively, due to increases in payroll and payroll related expenses, an increase in insurance costs related to property and liability coverages, and a general increase in operating cost as a result of the expansion activities of Bay Gas.

Depreciation expense increased $438,000 (22%) and $445,000 (29%), respectively, in fiscal years 2004 and 2003 due primarily to the second storage cavern which was placed in service in April 2003.

Other taxes consist primarily of property taxes and those taxes increased $249,000 (41%) and $85,000 (16%), respectively, as a result of the commencement of operations of Bay Gas’ second storage cavern.

Interest expense decreased $173,000 (4%) and $43,000 (1%), respectively, in fiscal years 2004 and 2003 due to scheduled principal payments.

21

Allowance for borrowed funds used during construction represents the capitalization of interest costs to construction work-in-progress. Capitalized interest costs decreased $1,109,000 for the 2004 fiscal year due to the completion of Bay Gas’ second storage cavern on April 1, 2003.

Minority interest reflects the minority partner’s share of pre-tax earnings of the Bay Gas limited partnership, of which EnergySouth’s subsidiary holds a controlling interest. Minority interest increased $109,000 (20%) and $95,000 (21%), respectively, during fiscal 2004 and 2003 due to increased pretax earnings of the limited partnership.

Other

Through Mobile Gas and EnergySouth Services, Inc., which are aggregated with EnergySouth, the holding company, the Company provides merchandising, financing, and other energy-related services to comprise the Other category. See Note 10 to the Consolidated Financial Statements for segment disclosure.

Income before income taxes from Other business activities decreased $97,000 (38%) in fiscal 2004 due primarily to a decline in interest income earned from financing activities, the establishment of additional bad debt provisions associated with financing activities and increases in operating expenses related to merchandising activities. Income before income taxes from Other business activities was $465,000 higher in fiscal 2003 due primarily to losses incurred during fiscal 2002 relating to the exit from the natural gas generator sales business and the closing of a specialty store.

Income Taxes

Income taxes fluctuate with the change in income before income taxes. The Company’s effective tax rate in 2004, 2003, and 2001 was 37.7%, 37.6%, and 36.9%, respectively. The components of income tax expense are reflected in Note 5 to the Consolidated Financial Statements.

Effects of Inflation

Inflation impacts the prices the Company must pay for labor and other goods and services required for operation, maintenance and capital improvements. For Mobile Gas, increases in these costs are recovered through the rate process. See Note 2 to the Consolidated Financial Statements. Changes in purchased gas costs are passed through to customers in accordance with the purchased gas adjustment provision of Mobile Gas’ rate tariffs.

Gas Supply

A primary goal of the Company is to provide gas at the lowest possible cost while maintaining a reliable long-term supply. To accomplish this goal the Company has diversified its gas supply by constructing and purchasing pipelines to access the vast gas reserves in its area,

22

both offshore and onshore. The Company has also contracted with certain of these sources for firm supply. To minimize the volatility of natural gas prices to its customers, Mobile Gas has implemented a gas supply strategy in which it enters into forward purchases to lock in prices for a majority of its expected gas sales during the upcoming winter heating season. Future minimum payments under third-party contracts for firm gas supply, which expire at various dates through the year 2011, are as follows: 2005 - $17,966,000; 2006 - - $1,170,000; 2007 - $1,187,000; 2008 - $1,187,000; 2009 - $1,187,000; and 2010 through 2011 - $2,028,000. A portion of firm supply requirements is met through the withdrawal of gas from the storage facility owned by Bay Gas. Mobile Gas has a gas storage agreement with Bay Gas to receive storage services for an initial period through 2014. Mobile Gas’ purchased gas adjustment provision in rate tariffs filed with the APSC allows a recovery of demand and commodity costs of purchased gas from customers. Should Mobile Gas’ customer base decline due to deregulation or other reasons, resulting in costs related to firm gas supply in excess of requirements, Mobile Gas believes it would be able to take one or more of the following actions: as part of the regulatory decision allowing other suppliers to serve current customers, secure the right to allocate firm gas supply costs to the new company supplying gas; reduce some excess gas supply costs through a negotiated settlement with suppliers; and/or pass-through excess gas supply costs to existing customers through the purchased gas component of customers’ rates.

Environmental

The Company is subject to various federal, state and local laws and regulations relating to the environment, which have not had a material effect on the Company’s financial position or results of operations. See Note 8 to the Consolidated Financial Statements for a discussion of certain environmental issues.

Liquidity and Capital Resources

The Company generally relies on cash generated from operations and, on a temporary basis, short-term borrowings, to meet working capital requirements and to finance normal capital expenditures. The Company issues debt and equity for longer term financing as needed. Impacts of operating, investing, and financing activities are shown on the Consolidated Statements of Cash Flows. Cash provided by operating activities was $27.0 million, $17.2 million and $22.1 million in 2004, 2003, and 2002, respectively. Cash provided from operating activities increased $10 million in 2004 as compared to 2003 due to an increase in net income, an increase in taxes payable, and an under-collection of increased gas costs from customers in the prior year. Cash provided from operating activities declined $4.9 million in 2003 as compared to 2002 due to an increase in accounts receivable and inventory, the option payment Bay Gas received in fiscal year 2002, and the under-collection of increased gas costs from customers. Partially offsetting the decrease in operating cash for fiscal 2003 was an increase in payables, deferred taxes, and net income.

Cash used in investing activities reflects the capital-intensive nature of the Company’s business. During 2004, 2003, and 2002, the Company used cash of $8.7 million, $15.7 million and $22.6 million, respectively, for construction of distribution and storage facilities, purchases of equipment and other general improvements. During fiscal 2002, Bay Gas

23

invested $17.3 million in the construction of the second cavern and completion of an 18-mile, 24-inch pipeline. In fiscal 2003, $4.9 million was invested by Bay Gas in the completion of the second cavern. In October 2002, Mobile Gas entered into a thirty-year franchise agreement with the City of Spanish Fort, and invested $1.5 million in the expansion of its distribution system into the City of Spanish Fort.

The Company expects fiscal 2005 capital expenditures by Mobile Gas to be approximately $9.5 million and by Bay Gas to be approximately $15.5 million. Mobile Gas’ projected 2005 expenditures include normal construction activity, including equipment purchases and other general improvements and will be funded by internal cash generation and short-term borrowings. Bay Gas’ anticipated capital expenditures include, subject to its ability to execute sufficient firm storage agreements for the additional cavern capacity, beginning construction and development of a third salt-dome storage cavern for storing 5 Bcf of natural gas, expanding injection and withdrawal capabilities and upgrading interstate pipeline interconnects. The expansion of storage facilities is expected to be funded through internal cash generation and the issuance of long-term debt.

Financing activities used cash of $13.1 million, $8.0 million and $7.0 million in fiscal 2004, 2003 and 2002, respectively. Long term debt payments and the payment of quarterly dividends primarily account for the cash used in each year. Dividend payments of $6.1 million, $5.6 million, and $5.3 million were offset by dividend reinvestment of $0.4 million, $0.4 million, and $0.3 million in 2004, 2003, and 2002, respectively. Fiscal 2004 included an additional optional principal payment of $1.7 million on Mobile Gas’ 7.27% Bonds. Another contributing factor in 2002 was the payoff of short-term borrowings which was partially funded by the issuance of $12.0 million of 6.9% First Mortgage Bonds by Mobile Gas. Receipts of $0.7 million, $1.2 million and $1.6 million in fiscal 2004, 2003 and 2002, respectively, from the exercise of stock options partially offset the cash used in financing activities.

Funds for the Company’s short-term cash needs are expected to come from cash provided by operations and borrowings under the Company’s revolving credit agreement which extends through January 31, 2005. At September 30, 2004 the Company had $20.0 million available for borrowing on its revolving credit agreement. The Company pays a fee for its committed lines of credit rather than maintain compensating balances. The commitment fee is 0.125% of the average daily unborrowed amount during the annual period of calculation. The Company believes it has adequate financial flexibility to meet its expected cash needs in the foreseeable future.

24

The table below summarizes the Company’s contractual obligations and commercial commitments as of September 30, 2004:

Off-Balance Sheet Arrangements

The Company has no “off-balance sheet arrangements” as such term is defined in Item 303(a)(4) of Regulation S-K.

Critical Accounting Policies

Regulatory Accounting. The Natural Gas Distribution segment is subject to regulation by the APSC and as such, accounts for its transactions according to the provisions of Statement of Financial Accounting Standards No. 71, “Accounting for the Effects of Certain Types of Regulation” (SFAS 71). This statement sets forth the application of accounting principles generally accepted in the United States of America for those companies whose rates are established by or are subject to approval by an independent third party regulator. The provisions of SFAS 71 require, among other things, that financial statements of a regulated enterprise reflect the actions of regulators, where appropriate. The application of this accounting policy allows the Company to defer expenses and income on the consolidated balance sheet as regulatory assets and liabilities when it is probable that those expenses and income will be allowed in the rate setting process in a period different from the period in which they would have been reflected in the consolidated statements of income of an unregulated company. These deferred regulatory assets and liabilities are then recognized in the consolidated statement of income in the period in which the same amounts are reflected in rates. See Note 1 to the Consolidated Financial Statements.

If any portion of the Natural Gas Distribution segment ceased to continue 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 consolidated balance sheet and included in the consolidated statement of income for the period in which the discontinuance of regulatory accounting treatment occurred.

Revenue Recognition. Mobile Gas recognizes revenues from the sales of natural gas and transportation services in the same period in which it delivers the related volumes to customers. Sales revenues from residential and certain commercial and industrial customers

25

are billed on the basis of scheduled meter reading cycles throughout the month. Mobile Gas records revenues for estimated deliveries of gas, not yet billed to these customers, from the meter reading date to the end of the accounting period. These revenues are included on the Company’s consolidated balance sheet as “Unbilled Revenue.” Included in the rates charged by Mobile Gas to temperature sensitive customers is a temperature rate adjustment rider which offsets the impact of unusually cold or warm weather on operating margin.

Reserves. EnergySouth companies establish reserves for uncollectible accounts receivable and slow moving merchandise, materials and supplies inventories. Such reserves are generally calculated based on currently available facts and on the application of a percentage to each aging category of receivables and inventory based on collection and sales experience, respectively. On certain specific receivables and inventory, the Company records an allowance based on currently available facts to reduce the net balance of the specific receivable or inventory item to the amount the Company reasonably expects to collect. Reserves for receivables are reported as “Allowance for Doubtful Accounts” on the balance sheet. Reserves for inventory are netted against the related asset account and reported on the balance sheet in “Materials, Supplies, and Merchandise.” The Company believes its reserves are adequate. However, actual results may differ from estimates, and estimates can be, and often are, revised either negatively or positively, depending upon actual outcomes or expectations based on the facts surrounding each potential exposure.

Employee Benefits. Employee benefits include a defined-benefit pension plan and other post-employment benefits for the benefit of substantially all full-time regular employees. Under the provisions of Statement of Financial Accounting Standards No. 87, “Employer’s Accounting for Pensions,” and Statement of Financial Accounting Standards No. 106, “Employer’s Accounting for Postretirement Benefits Other Than Pensions,” measurement of the obligations under the defined benefit pension plans and other post-retirement benefit plans is subject to a number of statistical factors and assumptions which attempt to anticipate future events. These factors include assumptions about the discount rate, expected return on plan assets and rate of future compensation increases as determined by the Company. In addition, the Company’s actuarial consultants also use subjective factors such as withdrawal and mortality rates to estimate the projected benefits obligation. The actuarial assumptions used may differ materially from actual results due to changing market and economic conditions, higher or lower withdrawal rates or longer or shorter life spans of participants. These differences may result in a significant impact on the amount of pension expense recorded in future periods. (See Note 7 to the Consolidated Financial Statements.)

At September 30, 2004, the discount rate used for pension and postretirement purposes was 6.0 percent. A hypothetical 25 basis point decrease in the annual discount rate would increase pension and postretirement benefit expense by $40,000 and $12,000, respectively. At September 30, 2004, the expected rate of return on assets for actuarial purposes was 8.25 percent and 7.75 percent for pension and post-retirement benefits, respectively. A hypothetical 25 basis point decrease in the expected rate of return on assets would increase pension and postretirement expense by $78,000 and $9,000, respectively. At September 30, 2004, the rate of compensation increase used for actuarial purposes was 4.5 percent. A hypothetical 25 basis point increase in the expected rate of future compensation increases would increase pension expense by $31,000.

Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosure.

None.

Item 9A. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this report, an evaluation (the “Evaluation”) was carried out, under the supervision and with the participation of the Company’s President and Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operation of the Company’s disclosure controls and procedures (“Disclosure Controls”). Based on the Evaluation, the CEO and CFO concluded that the Company’s Disclosure Controls are effective in timely alerting them to material information required to be included in the Company’s periodic SEC reports.

Changes in Internal Control

Internal controls for financial reporting were also evaluated and there have been no significant changes in internal controls or in other factors that could significantly affect those controls subsequent to the date of their last evaluation.

Limitations on the Effectiveness of Controls

A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Board of Directors and Stockholders of
EnergySouth, Inc.
Mobile, Alabama

We have audited the accompanying consolidated balance sheets of EnergySouth, Inc. and subsidiaries (the “Company”) as of September 30, 2004 and 2003, and the related consolidated statements of income, stockholders’ equity, and cash flows for each of the three years in the period ended September 30, 2004. Our audits also included the financial statement schedule listed in the Index as schedule II. These financial statements and financial statement schedule are the responsibility of the Company’s management. Our responsibility is to express an opinion on these financial statements and financial statement schedule based on our audits.

We conducted our audits in accordance with standards of the Public Company Accounting Oversight Board (United States). Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement. An audit includes examining, on a test basis, evidence supporting the amounts and disclosures in the financial statements. An audit also includes assessing the accounting principles used and significant estimates made by management, as well as evaluating the overall financial statement presentation. We believe that our audits provide a reasonable basis for our opinion.

In our opinion, such consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company at September 30, 2004 and 2003, and the results of their operations and their cash flows for each of the three years in the period ended September 30, 2004, in conformity with accounting principles generally accepted in the United States of America. Also, in our opinion, the financial statement schedule, when considered in relation to the basic consolidated financial statements taken as a whole, presents fairly, in all material respects, the information set forth therein.
