SEMCO ENERGY, INC.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)


NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES

Under the rules and regulations of the Securities and Exchange Commission
for Form 10-Q Quarterly Reports, certain footnotes and other financial statement
information normally included in the year-end financial statements of SEMCO
Energy, Inc. and its subsidiaries (the "Company") have been condensed or omitted
in the accompanying unaudited financial statements. These financial statements
prepared by the Company should be read in conjunction with the financial
statements and notes thereto included in the Company's 2001 Annual Report on
Form 10-K filed with the Securities and Exchange Commission. The information in
the accompanying financial statements reflects, in the opinion of the Company's
management, all adjustments (which include only normal recurring adjustments)
necessary for a fair statement of the information shown, subject to year-end and
other adjustments, as later information may require. Certain reclassifications
have been made to the prior periods' financial statements to conform with the
2002 presentation.

USE OF ESTIMATES - The preparation of financial statements in conformity
with generally accepted accounting principles 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.

GAS IN UNDERGROUND STORAGE - Effective April 1, 2002, the Battle Creek
Division of the Company's Gas Distribution business changed its method of
accounting for gas inventory from last-in, first-out (LIFO) to average cost.
This change in accounting principles was made in order to provide a better
matching of expenses with revenues and make Battle Creek's accounting for gas
inventory consistent with the Company's other gas distribution divisions and
other Michigan gas distribution companies. This accounting change was not
material to the financial statements, and, accordingly, no retroactive
restatement of prior years' financial statements was made.

COMPREHENSIVE INCOME - The Company's comprehensive income (loss) for the
three, nine and twelve months ended September 30, 2002 and September 30, 2001 is
summarized in the following table.

SEMCO ENERGY, INC.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
(Continued)


NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

NEW ACCOUNTING STANDARDS - On January 1, 2002, the Company adopted
Statement of Financial Accounting Standards ("SFAS") 141, "Business
Combinations" and SFAS 142, "Goodwill and Other Intangible Assets." SFAS 141
addresses financial accounting and reporting for all business combinations and
requires that all business combinations entered into subsequent to June 2001 be
recorded under the purchase method. This Statement also addresses financial
accounting and reporting for goodwill and other intangible assets acquired in a
business combination at acquisition. SFAS 142 addresses financial accounting
and reporting for intangible assets acquired individually or with a group of
other assets at acquisition. This Statement also addresses financial accounting
and reporting for goodwill and other intangible assets subsequent to their
acquisition.
Effective with the date of adoption of these Statements the Company ceased
Goodwill amortization, which has reduced amortization expense for the nine
months ended September 30, 2002 by approximately $2.1 million after income taxes
(or $0.11 per share based on the current level of outstanding common stock).
The Company is also required to complete a transition impairment test in
the year of adoption, and perform subsequent impairment tests on the remaining
goodwill balance annually or at any time when events occur which could impact
the value of the Company's business segments. If an impairment test of goodwill
shows that the carrying amount of the goodwill is in excess of the fair value, a
corresponding impairment loss would be recorded in the consolidated statements
of income. The transition impairment tests were performed for the Company's
business units and the results of those tests indicate that no impairment of the
Company's goodwill balances existed as of January 1, 2002. The 2002 annual
impairment test has also been performed for the Company's construction services
business segment and indicates that there is no impairment of goodwill. As a
result, there was no change in the carrying amount of goodwill at September 30,
2002 when compared to December 31, 2001. The 2002 annual impairment tests for
the remaining business units will be conducted during the fourth quarter of
2002.
The following table presents what would have been reported as net income
(loss) available to common shareholders and the related per share amounts on a
basic and diluted basis in all periods presented, exclusive of amortization
expense (including any related tax effects) recognized in those periods related
to goodwill.

SEMCO ENERGY, INC.
NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
(Unaudited)
(Continued)


NOTE 1 - SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

On January 1, 2002, the Company also adopted SFAS 144, "Accounting for the
Impairment or Disposal of Long-Lived Assets," which replaces SFAS 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be Disposed of" and Accounting Principles Board ("APB") Opinion 30, "Reporting
Results of Operations-Reporting the Effects of Disposal of a Segment of a
Business, and Extraordinary, Unusual and Infrequently Occurring Events and
Transactions."
SFAS 144 requires long-lived assets to be measured at the lower of either
the carrying amount or the fair value less the cost to sell the assets, whether
reported in continuing operations or in discontinued operations. Therefore,
discontinued operations will no longer be measured at net realizable value or
include amounts for operating losses that have not yet occurred.
SFAS 144 also broadens the reporting of discontinued operations to include
all components of an entity with operations that can be distinguished from the
rest of the entity and that will be eliminated from the ongoing operations of
the entity in a disposal transaction. The adoption of SFAS 144 will result in
the Company accounting for any future impairment or disposal of long-lived
assets under the provisions of SFAS 144, but has not changed the accounting used
for previous asset impairments or disposals.
In June 2001, the FASB issued SFAS 143, "Accounting for Asset Retirement
Obligations," effective January 1, 2003. The Standard requires entities to
record the fair value of a liability for an asset retirement obligation in the
period in which it is incurred.
When the liability is initially recorded, the entity capitalizes a cost by
increasing the carrying amount of the related long-lived asset. Over time, the
liability is accreted to its present value each period, and the capitalized cost
is depreciated over the useful life of the related asset. Upon settlement of
the liability, an entity either settles the obligation for its recorded amount
or incurs a gain or loss upon settlement. The Company is currently studying
SFAS 143 but has not quantified the effects of adoption on its financial
statements.
In April 2002, the FASB issued SFAS 145, "Rescission of FASB Statements No.
4, 44 and 64, Amendment of FASB Statement No. 13, and Technical Corrections".
SFAS 145 eliminates SFAS 4, Reporting Gains and Losses from Extinguishment of
Debt" ("SFAS 4") and thus allows for only those gains or losses on the
extinguishment of debt that meet the criteria of extraordinary items to be
treated as such in the financial statements. SFAS 145 also amends SFAS 13,
Accounting for Leases" ("SFAS 13") to require sale-leaseback accounting for
certain lease modifications that have economic effects that are similar to
sale-leaseback transactions. The provisions of this Statement relating to the
rescission of SFAS 4 are effective for fiscal years beginning after May 15,
2002. The provisions of this Statement relating to the amendment of SFAS 13 are
effective for transactions occurring after May 15, 2002. All other provisions
of this Statement are effective for financial statements issued on or after May
15, 2002.
In June 2002, The FASB issued SFAS 146, "Accounting for Costs Associated
with Exit or Disposal Activities". SFAS 146 requires that the liability for
costs associated with exit or disposal activities be recognized when incurred,
rather than at the date of a commitment to an exit or disposal plan. SFAS 146
is to be applied prospectively to exit or disposal activities initiated after
December 31, 2002.
The Company is in the process of evaluating the impact of SFAS 145 and SFAS
146 on its financial statements, and does not expect the impact to be material.

NOTE 2 - SHORT-TERM BORROWINGS AND CAPITALIZATION

SHORT-TERM BORROWINGS - On June 25, 2002, the Company entered into a $145
million credit agreement with a group of banks, replacing four lines of credit
totaling $145 million, which were due to expire. The new agreement, all of
which is committed, consists of an $80 million three-year revolver and a $65
million 364-day facility, with a one-year term loan option. On September 30,
2002, $31.6 million of these credit facilities was unused.

LONG-TERM DEBT - During September 2002, the Company issued $30 million of
6.49% unsecured Senior Notes due 2009. Interest on the Senior Notes is payable
semiannually. The proceeds from the sale were used to redeem $30 million of
6.83% Senior Notes, which were due to mature on October 1, 2002.

COMMON STOCK EQUITY - On October 17, 2002, the Company's Board of Directors
declared a quarterly cash dividend of $0.125 per share on the Company's common
stock. The dividend is payable on November 15, 2002 to shareholders of record
at the close of business on November 1, 2002.
In August 2002, the Company paid a quarterly cash dividend of $0.125 per
share on its common stock. The total cash dividend was approximately $2.3
million of which $.4 million was reinvested by shareholders into common stock
through participation in the Direct Stock Purchase and Dividend Reinvestment
Plan ("DRIP"). The cash dividend for the nine months ended September 30 2002,
was $8.4 million, of which $1.4 million was reinvested by shareholders through
participation in the DRIP. During the three and nine months ended September 30,
2002, the Company issued approximately 70,300 and 285,700 shares of Company
common stock, respectively, to meet the dividend reinvestment and stock purchase
requirements of its DRIP participants. Also during the three and nine months
ended September 30, 2002, the Company issued approximately 25,000 and 37,400
shares of its common stock, respectively, to certain of the Company's employee
benefit plans. During the first and second quarter of 2002, the Company
purchased 19,400 and 40,200 shares of its common stock, respectively, on the
open market to contribute to certain of its employee benefit plans.


NOTE 3 - RISK MANAGEMENT ACTIVITIES AND DERIVATIVE TRANSACTIONS

The Company's business activities expose it to a variety of risks,
including commodity price risk and interest rate risk. The Company's management
identifies risks associated with the Company's business and determines which
risks it wants to manage and which types of instruments it should use to manage
those risks.
The Company records all derivative instruments it enters into under the
provisions of SFAS 133, "Accounting for Derivative Instruments and Hedging
Activities," and SFAS 137 and SFAS 138, which were amendments to SFAS 133
(hereinafter collectively referred to as "SFAS 133"). SFAS 133 requires that
every derivative instrument (including certain derivative instruments embedded
in other contracts) be recorded in the statement of financial position, as
either an asset or liability, measured at its fair value. SFAS 133 also
requires that changes in the derivative's fair value be recognized currently in
earnings unless specific hedge accounting criteria are met. Special accounting
for qualifying hedges allows a derivative's gains and losses to offset related
results on the hedged item in the income statement, and requires that a company
must formally document, designate, and assess the effectiveness of transactions
that receive hedge accounting.
An affiliate, in which the Company has a 50% investment, uses an interest
rate swap agreement to hedge the variable interest rate payments on its
long-term debt. This agreement qualifies under the provisions of SFAS 133 as a
cash flow hedge. As a result of this interest rate swap agreement, the
Company's Consolidated Statements of Financial Position, at September 30, 2002

NOTE 5 - BUSINESS SEGMENTS

The Company operates four reportable business segments: (1) gas
distribution; (2) construction services; (3) information technology services;
and (4) propane, pipelines and storage. The latter three segments are sometimes
referred to together as the "diversified businesses". For information regarding
the determination of reportable business segment, refer to Note 10 of the Notes
to the Consolidated Financial Statements in the Company's 2001 Annual Report on
Form 10-K.
The Company's gas distribution segment distributes and transports natural
gas to approximately 268,000 customers in the state of Michigan and
approximately 110,000 customers in the state of Alaska. The construction
services segment ("Construction Services") currently conducts most of its
business in the midwestern, southern and southeastern areas of the United
States. Its primary service is the installation of underground natural gas
mains and service lines. Other services include the installation and
maintenance of compressor and pipeline stations. The information technology
service segment ("IT Services") is headquartered in Michigan and provides IT
infrastructure outsourcing services, and other IT services with a focus on
mid-range computers, particularly the IBM I-Series (AS-400) platform. The
Company's other business segments currently account for a large portion of IT
Services revenues. The propane, pipelines and storage segment sells more than
four million gallons of propane annually to retail customers in Michigan's upper
peninsula and northeast Wisconsin and operates natural gas transmission and
storage facilities in Michigan.
The accounting policies of the operating segments are the same as those
described in Notes 1 and 10 of the Notes to the Consolidated Financial
Statements in the Company's 2001 Annual Report on Form 10-K, except that
intercompany transactions have not been eliminated in determining individual
segment results. The following table provides business segment information as
well as a reconciliation ("Corporate and other") of the segment information to
the applicable line in the Consolidated Financial Statements. Corporate and
Other includes corporate related expenses not allocated to segments,
intercompany eliminations and results of other smaller operations.

NOTE 6 - COMMITMENTS AND CONTINGENCIES

ENVIRONMENTAL MATTERS - Prior to the construction of major natural gas
pipelines, gas for heating and other uses was manufactured from processes
involving coal, coke or oil. The Company owns seven Michigan sites, which
formerly housed such manufacturing facilities, and expects that it will
ultimately incur investigation and remedial action costs at some of these sites.
The Company has closed a related site with the approval of the appropriate
environmental regulatory authority in the State of Michigan, and has developed
plans and conducted preliminary field investigations at two other sites. The
extent of the Company's liabilities and potential costs in connection with these
sites cannot be reasonably estimated at this time. In accordance with an MPSC
accounting order, any environmental investigation and remedial action costs will
be deferred and amortized over ten years. Rate recognition of the related
amortization expense will not begin until after a prudence review in a general
rate case.

PERSONAL PROPERTY TAXES - On November 7, 2002, the MPSC issued an order
requiring each natural gas and electric utility company subject to its
jurisdiction to show cause as to why each such utility should not reduce its
rates to reflect the new personal property valuation tables that were placed in
effect in 2000 by the Michigan State Tax Commission and why it should not refund
to the ratepayers any recovery amounts it receives as refunds from taxing
jurisdictions as it implements the new valuation tables. Responses to the Order
must be filed with the MPSC by December 9, 2002.
As of September 30, 2002, the Company had a receivable of approximately $4
million recorded for the Company's estimated recovery of prior year excess
property tax payments resulting from the application of these new tables." The
Company is currently studying the Order and its potential impact on this
estimated receivable. For further information regarding the new valuation
tables, see Note 13 of the Notes to Consolidated Financial Statements in the
Company's 2001 Annual Report.

OTHER - In the normal course of business, the Company may be a party to
certain lawsuits and administrative proceedings before various courts and
government agencies. These lawsuits and proceedings may involve personal
injury, property damage, contractual issues and other matters. Management
cannot predict the ultimate outcome of any pending or threatened litigation or
of actual or possible claims; however, management believes resulting
liabilities, if any, will not have a material adverse impact upon the Company's
financial position or results of operations. Refer to Note 13 of the Notes
to the Consolidated Financial Statements in the Company's 2001 Annual Report on
Form 10-K for further details regarding other commitments and contingencies.


NOTE 7 - DISCONTINUED OPERATIONS

In December 2001, the Company's board of directors approved a plan to redirect
the Company's business strategy, which includes the divestiture of its
engineering services business. The planned divestiture of the Company's
engineering services business has been accounted for as a discontinued operation
and, accordingly, the operating results and the estimated loss on the disposal
of this business segment are segregated and reported as discontinued operations
in the Consolidated Statements of Income, with prior years restated. In the
fourth quarter of 2001, the Company recorded a loss of $5.0 million, net of
income taxes, for the estimated loss the Company expects to incur on the
disposal of its engineering business segment including estimated losses from
operations during the phase-out period. As of September 30, 2002, no
adjustments to this estimated loss were required. See Note 8 for further
information regarding the sale of this business.

aspects of the sale. Any required adjustments to the estimated loss, recorded
in December 2001, for the sale of this business, including the provision for
losses during phase-out, will be reflected in discontinued operations during the
fourth quarter of 2002. The Company expects that any adjustment will not be
material but cannot provide assurance of this until it has completed its

RESULTS OF OPERATIONS.


RESULTS OF OPERATIONS

SEMCO Energy, Inc. and its subsidiaries (the "Company") had a net loss of
$7.0 million (or $0.38 per share) for the quarter ended September 30, 2002
compared to a net loss of $6.6 million (or $0.37 per share) for the quarter
ended September 30, 2001. All references to earnings per share in this
Management's Discussion and Analysis are on a diluted basis. For information
related to the calculation of diluted earnings per share, refer to Note 4 of the
Notes to the Consolidated Financial Statements. On a weather-normalized basis,
the net loss for the three months ended September 30, 2002 would have been
approximately $6.3 million (or $0.34 per share) compared to a net loss of
approximately $6.3 million (or $0.35 per share) for the same period of the prior
year.
The Company had net income of $4.4 million (or $0.24 per share) for the
nine months ended September 30, 2002 compared to a net loss of $.9 million (or
$0.05 per share) for the nine months ended September 30, 2001. On a
weather-normalized basis, the net income for the nine months ended September 30,
2002 would have been approximately $6.6 million (or $0.36 per share) compared to
net income of approximately $2.8 million (or $0.16 per share) for the same
period of the prior year.
The Company had a net loss of $1.1 million (or $0.06 per share) for the
twelve months ended September 30, 2002 compared to net income of $11.6 million
(or $0.61 per share) for the twelve months ended September 30, 2001. On a
weather-normalized basis, net income would have been approximately $2.8 million
(or $0.15 per share) for the twelve months ended September 30, 2002, compared to
net income of approximately $15.9 million (or $0.84 per share) for the same
period ended September 30, 2001. The results for the twelve months ended
September 30, 2002 also include several unusual items which reduced net income
by $10.6 million. The unusual items include losses from discontinued
operations, restructuring charges, asset impairments and other unusual items.
Refer to Management's Discussion and Analysis and Note 14 of the Notes to the
Consolidated Financial Statements in the Company's 2001 Annual Report on Form
10-K for further information regarding these unusual items.
The Company's largest business segment, natural gas distribution, is
seasonal in nature and depends on the winter months for the majority of its
operating revenue. As a result, a substantial portion of the Company's annual
income is earned during the first and fourth quarters of the year. In addition,
the Company's construction services business segment is also seasonal in nature
and earns most of its income during the summer and fall months and incurs losses
during the winter and spring months. Therefore, the Company's results of
operations for the three and nine months ended September 30, 2002 and 2001 are
not necessarily indicative of results for a full year.

The Company operates four reportable business segments: (1) gas
distribution; (2) construction services; (3) information technology services;
and (4) propane, pipelines and storage. The latter three segments are sometimes
referred to together as the "diversified businesses". Refer to Note 5 of the
Notes to the Consolidated Financial Statements for further information regarding
business segments and a summary of operating revenues and operating income by
business segment.
The business segment analyses and other discussions on the next several
pages provide additional information regarding variations in operating results
when comparing the three, nine and twelve-month periods ended September 30, 2002
to the same periods of the prior year. The Company evaluates the performance of
its business segments based on the operating income generated. Operating income
does not include income taxes, interest expense, discontinued operations or
other non-operating income and expense items. A review of the non-operating
items follows the business segment discussions.

THE IMPACT OF WEATHER

The Company determines the impact of weather on its operating results by
comparing actual gas consumption per customer during a period to the average of
weather-normalized customer gas consumption during previous periods. The
difference is multiplied by the average number of customers during the period to
arrive at the total increase or decrease in consumption associated with weather.
The total increase or decrease in consumption is multiplied by the actual margin
per unit of consumption during the period to arrive at the impact of weather for
the period. The weather-normalized customer consumption used in this
calculation is determined by adjusting actual customer gas consumption during a
particular period by a ratio, the numerator of which is an average of degree
days during the same periods in the prior fifteen years, and the denominator of
which is the actual degree days for that period.
The Company determines the percent (%) that weather is warmer or colder
than normal for a particular period by computing the deviation of actual degree
days for that period from the average of degree days during the same period in
the prior fifteen years and dividing the deviation by such fifteen year average.


GAS DISTRIBUTION

The Company's gas distribution business segment consists of operations in
Michigan and Alaska. The Michigan operation is sometimes referred to as "SEMCO
Gas" and the Alaska operation is sometimes referred to as "ENSTAR". These
operations are referred to together as the "Gas Distribution Business".
The Gas Distribution Business had an operating loss of $.7 million for the
quarter ended September 30, 2002, compared to an operating loss of $2.2 million
for the quarter ended September 30, 2001. On a weather-normalized basis, the
Gas Distribution Business would have had operating income of approximately $.4
million for the third quarter of 2002 compared to an operating loss of
approximately $1.5 million for the same period of the prior year.

GAS DISTRIBUTION (CONTINUED)

GAS SALES MARGIN - During the three months ended September 30, 2002, gas
sales margin decreased by $.5 million when compared to the same period in 2001.
The decrease is due primarily to warmer weather and lower gas cost savings,
partially offset by the addition of new customers and customers switching from
the Company's aggregated transportation service ("ATS") program back to gas
sales service.
During the nine months ended September 30, 2002, gas sales margin increased
by $4.7 million when compared to the same period in 2001. The increase is due
primarily to the impact of colder weather, increased gas cost savings, the
addition of new customers, and customers switching from the Company's aggregated
transportation service ("ATS") program back to gas sales service.
Weather during the third quarter of 2002 was 33% warmer than normal in
Michigan and Alaska combined, while the weather during the third quarter of 2001
was 4% colder than normal. However, in Alaska, weather was 5% warmer than
normal during the third quarter of 2001. Under normal weather conditions, gas
sales margin for the quarter ended September 30, 2002 would have been higher by
approximately $1.0 million and for the quarter ended September 30, 2001 would
have been higher by approximately $.7 million.
Weather during the nine months ended September 30, 2002 was 4% warmer than
normal in Michigan and Alaska combined, while the weather during the nine months
ended September 30, 2001 was 9% warmer than normal. Under normal weather
conditions, gas sales margin for the nine months ended September 30, 2002 would
have been higher by approximately $3.4 million and for the nine months ended
September 30, 2001 would have been higher by approximately $6.1 million.
Under the terms of certain of the Company's third-party natural gas supply
and management agreements for its Michigan operations, certain gas cost savings
are passed through to the Company. The decrease in gas cost savings during the
third quarter of 2002 was due primarily to reinstating the gas cost recovery
("GCR") mechanism, effective April 1, 2002, for Michigan customers subject to
the jurisdiction of the MPSC ("MPSC Customers"). As a result of reinstating the
GCR mechanism, the Company no longer retains the gas cost savings on sales to
MPSC Customers. The Company continues to retain any gas cost savings on sales
to customers subject to the jurisdiction of the City Commission of Battle Creek.
The increase in gas cost savings during the nine months ended September 30,
2002, the majority of which occurred in the first quarter of 2002, was due in
part to the effective management of the Company's gas supply under certain of
these agreements. In addition gas cost savings were lower during the first half
of 2001, compared to previous periods, as a result of purchasing gas with a
higher thermal content. A significant portion of the gas cost savings realized
during the first quarter of 2002 is non-recurring because it relates to MPSC
Customers. For further information regarding the Company's natural gas supply
and management agreements and the GCR mechanism, refer to Note 2 of the Notes to
Consolidated Financial Statements in the Company's 2001 Annual Report on Form
10-K.
The ATS program for residential customers, which was effective from April
1, 1999, through March 31, 2002, provided all Michigan residential customers the
opportunity to purchase their gas from a third-party supplier, while allowing
the Gas Distribution Business to continue charging the existing distribution
fees and customer fees. Distribution and customer fees associated with
customers who switched to third-party gas suppliers were recorded in gas
transportation revenue rather than gas sales revenue, because the Company acted
as a transporter for those customers. During 2001 and 2002 certain ATS
customers switched back to the Company's gas sales service because the
third-party suppliers they were utilizing stopped participating in the ATS
program, primarily due to a significant increase in the market price of natural
gas. In addition, when the ATS program for residential customers ended on March
31, 2002, all remaining ATS customers became gas sales customers.

RESULTS OF OPERATIONS.


GAS DISTRIBUTION (CONTINUED)

Gas sales margin for the twelve months ended September 30, 2002 increased
by $1.4 million, when compared to the twelve months ended September 30, 2001.
The increase is due primarily to the impact of colder weather, the addition of
new customers, and customers switching from the Company's ATS program back to
gas sales service.
Weather during the twelve months ended September 30, 2002 was 5% warmer
than normal in Michigan and Alaska combined, while the weather during the twelve
months ended September 30, 2001 was 6% warmer than normal. Under normal weather
conditions, gas sales margin for the twelve months ended September 30, 2002 and
2001 would have been higher by approximately $5.7 million and $7.3 million,
respectively.

GAS TRANSPORTATION REVENUE - For the three, nine and twelve-month periods
ended September 30, 2002, gas transportation revenue increased by $.1 million,
$.7 million and $.3 million, respectively, when compared to the same periods
ended September 30, 2001. The primary cause of these increases was an increase
in industrial and commercial transportation volumes, as a result of cooler
weather in Alaska for the first three quarters of 2002, in comparison to the
same periods in 2001. This was offset partially by a decrease in transportation
volumes for power companies and the impact of ATS customers switching from the
ATS program back to gas sales service during each of the periods. As discussed
above, under the ATS program, the Company charged ATS customers the same
distribution fees and customer fees that were charged to gas sales service
customers.

OTHER OPERATING REVENUE - Other operating revenue for the three and
nine-month periods ended September 30, 2002, was $.8 million and $2.6 million,
respectively, compared to $.6 million and $2.3 million, respectively, for the
same periods ended September 30, 2001. The increases for the three and
nine-month periods were due primarily to fees on new transmission pipelines in
service, offset partially by a reduction in ATS balancing fees as a result of
ATS customers switching back to gas sales service. Other operating revenue for
the twelve months ended September 30, 2002 was $3.3 million, compared to $3.7
million for the twelve months ended September 30, 2001. The $.4 million
decrease was due primarily to a reduction in ATS balancing fees as a result of
ATS customers switching back to gas sales service, offset partially by an
increase in fees on new transmission pipelines in service.

OPERATING EXPENSES - Operating expenses of the Gas Distribution Business
decreased by $1.6 million and $1.8 million, respectively, for the three and
nine-month periods ended September 30, 2002. The decreases were the result of a
number of offsetting factors. Amortization expense decreased by $1.0 million
and $3.0 million, respectively, during the three and nine-month periods ended
September 30, 2002, when compared to the same periods in 2001. The decreases
were due to the elimination of goodwill amortization as a result of the adoption
of SFAS 142. For further information on SFAS 142 and its impact on goodwill,
see Note 1 of the Notes to the Consolidated Financial Statements. During the
three and nine-month periods ended September 30, 2002, operation and maintenance
expense decreased by $1.1 million and $.5 million due primarily to general cost
cutting measures and the impact of a reduction in workforce related to the
Company's redirected business strategy, offset partially by higher employee
benefit costs, including pension expense, health care costs and retiree medical
costs. During the three and nine-month periods ended September 30, 2002,
property and other taxes increased by $.1 million and $.3 million, respectively,
due primarily to property taxes on additional property, plant and equipment
placed in service. Depreciation expense also increased due primarily to
additional property, plant and equipment placed in service.

GAS DISTRIBUTION (CONTINUED)

Operating expenses for the twelve months ended September 30, 2002 increased
by $2.1 million when compared to the twelve months ended September 30, 2001.
Included in this increase is approximately $1.1 million of restructuring charges
recorded in the fourth quarter of 2001. The remainder of the increase was
primarily the result of an increase in operation and maintenance expenses of
$2.0 million, an increase in general business tax expenses of $1.0 million and
an increase in depreciation expense of $1.0 million. The increase in operating
expenses is due largely to higher employee related costs, including pension
expense, health care costs and retiree medical costs, offset partially by the
cost cutting measures and the reduction in workforce discussed above. The
increase in general business tax expenses is due primarily to higher property
taxes related to new property placed in service. Depreciation expense increased
due to additional property, plant and equipment placed in service. These
increases were offset by a decrease in amortization expense of $3.0 million due
to the reasons discussed above.

REGULATORY MATTERS - The Regulatory Commission of Alaska ("RCA") has been
conducting a review of ENSTAR's rates. The Company received an Order dated
August 8, 2002 from the RCA on its review of rates for ENSTAR based on
normalized data for the year 2000. In its Order the RCA established a revenue
requirement of $107.6 million and a 12.55% return on equity. In response to a
petition by ENSTAR, the RCA issued an additional Order dated September 16, 2002
which revised the indicated annual revenue reduction from $2.1 million to $2.0
million, which was 1.84% of ENSTAR's revenue in the normalized 2000 test year.
The Order required ENSTAR to implement the rate reduction by September 27, 2002
on an across-the-board basis. The RCA also required ENSTAR to file an updated
cost of service study by September 9, 2002 and a rate design in February 2003,
with a hearing on the rate design filing scheduled for late summer 2003. ENSTAR
has implemented the rate reduction and filed the cost of service study as
required.


CONSTRUCTION SERVICES

The Company's Construction Services business ("Construction Services") is
seasonal. As a result, it generally incurs operating losses during the winter
and spring months when underground construction and related services are
inhibited by weather, and generates the majority of its operating income during
the summer and fall months.

CONSTRUCTION SERVICES (CONTINUED)

OPERATING REVENUES - The operating revenues of Construction Services for
the three month period ended September 30, 2002 were $33.9 million, which
represents a $7.5 million decrease in comparison to the same period ended
September 30, 2001. The decrease was due primarily to customers in the northern
regions of the country cutting back or delaying projects this year in light of
uncertainty surrounding the economy and other factors. During the third quarter
of 2002, customers in the southern region of the country also delayed certain
large projects. The Company expects this trend to continue through the end of
2002.
The operating revenues of Construction Services for the nine and twelve
month periods ended September 30, 2002 were $96.0 million and $128.8 million,
respectively, which represent a $2.6 million and $2.3 million increase,
respectively, over the same periods ended September 30, 2001. These increases
are due primarily to an increase in construction projects in the southern
regions of the United States during the last half of 2001 and the first half of
2002. This was offset partially by reduced construction activity in the
northern regions of the country during 2002 and in the southern region during
the third quarter of 2002, as discussed above.

OPERATING INCOME - Construction Services had operating income of $.6
million and $1.2 million and an operating loss of $2.7 million, respectively,
for the three, nine and twelve-month periods ended September 30, 2002, compared
to operating income of $3.6 million, $2.6 million and $5.4 million,
respectively, for the three, nine and twelve-month periods ended September 30,
2001. These decreases were due primarily to the reduced construction activity,
particularly during the third quarter of 2002, and lower than expected margins
on some of the work performed. The Company believes that the softening economy
has caused many customers to delay or cancel certain construction projects,
which has changed the mix of work available to Construction Services. The mix
of work has included more lower-margin work at certain business units because of
the competition for the limited supply of available work. The reduced
construction activity has also eroded margins because of the time lag required
to reduce the fixed costs associated with the prior level of revenues. Certain
fixed costs also cannot be eliminated for a number of reasons, including the
expectation that work will resume on many of the projects. In addition, the
overall operating performance for the northern region of Construction Services
has been below the Company's expectations.
During the nine and twelve-month periods ended September 30, 2002, the
factors causing the decreases were offset partially by income generated from the
increase in construction projects in the southern regions of the United States
during the last half of 2001 and the first half of 2002. The decrease during
the twelve months ended September 30, 2002 was also due in part to restructuring
and impairment charges of $3.1 million recorded in the fourth quarter of 2001,
in addition to the factors discussed above.

ended September 30, 2002, when compared to the same period ended September 30,
2001,is due primarily to fewer special projects with affiliate customers offset
partially by an increase in business with non-affiliate customers.
Operating revenues for the twelve months ended September 30, 2002 were $9.8
million, compared to $9.6 million for the twelve months ended September 30,
2001. Of these amounts, $8.1 million and $9.4 million for these same periods,
respectively, represent sales to affiliates. The increase in operating revenues
of $.2 million for the twelve-month period ended September 30, 2002 is due
primarily to the addition of affiliate and non-affiliate customers offset
partially by fewer special projects with affiliate customers.

OPERATING INCOME - Operating income for the three months ended September
30, 2002, when compared to the same period ending September 30, 2001, decreased
by less than $.1 million. Operating income for IT Services for the nine months
ended September 30, 2002 was $.4 million, which is essentially unchanged from
the same period ending September 30, 2001. Operating income for the twelve
months ended September 30, 2002 decreased by $.1 million, compared to same
period ended September 30, 2001. This decrease is due primarily to more special
project services performed during the twelve-month period ended September 30,
2001. Special project services typically provide higher margins.

OPERATING REVENUES - The operating revenues of the Company's propane,
pipelines and storage business for the three, nine and twelve-month periods
ended September 30, 2002 were $1.1 million, $4.8 million and $6.8 million,
respectively, compared to $1.3 million, $5.4 million and $7.8 million,
respectively, for the same periods ended September 30, 2001. The decreases for
the three, nine and twelve-month periods were due primarily to lower propane
distribution revenues resulting from warmer weather in the Company's propane
distribution service area and a reduction in the market price for propane.

OPERATING INCOME - Operating income from the propane, pipelines and storage
business for the third quarter of 2002 decreased by less than $.1 million when
compared to the same period in 2001. Operating income for the nine and twelve
month periods ended September 30, 2002, when compared to the same periods in
2001, decreased by approximately $.1 million. These decreases were due
primarily to warmer weather during the first and third quarters of 2002 and the
fourth quarter of 2001, which reduced propane sales and margins. This was
offset partially by the impact of colder weather during the second quarter of
2002.

periods ended September 30, 2002 decreased by $.1 million, $.7 million, and $1.2
million, respectively, when compared to the same periods ended September 30,
2001. The decrease in interest expense during the third quarter was due
primarily to income from an interest rate swap agreement which terminated in
August 2002. The decrease in interest expense for the nine and twelve-month
periods ended September 30, 2002 was due primarily to lower short-term interest
rates and income from the interest rate swap.

OTHER INCOME - Other income for the three months ended September 30, 2002
increased by $.4 million when compared to the same period ended September 30,
2001. The increase was due primarily to an engineering project performed by the
Gas Distribution business for a third party.

OTHER INCOME AND DEDUCTIONS (CONTINUED)

Other income for the nine months ended September 30, 2002 was essentially
unchanged when compared to the same period ended September 30, 2001. The income
from the engineering project discussed above was offset by losses on the sale of
equipment and lower interest income.
The decrease of $.5 million during the twelve months ended September 30,
2002, when compared to the same period of 2001, was due to the previously
discussed factors affecting the nine months ended September 30, 2002, along with
a write-off of certain assets in the fourth quarter of 2001.


INCOME TAXES

Income taxes for the three and twelve-month periods ended September 30,
2002 decreased by $.3 million and $2.9 million, respectively, when compared to
the same periods ended September 30, 2001. Income taxes for the nine months
ended September 30, 2002 increased by approximately $2.7 million, when compared
to the same period ended September 30, 2001. The change in income taxes, when
comparing one period to another, is due primarily to changes in earnings before
income taxes and dividends on trust preferred securities and any adjustments
necessary for compliance with tax laws and regulations.


DIVIDENDS ON TRUST PREFERRED SECURITIES, NET OF INCOME TAX

Dividends on Trust Preferred Securities, net of Income taxes, for the
three, nine and twelve-month periods ended September 30, 2002 were essentially
unchanged at $2.2 million, $6.5 million and $8.6 million when compared to the
same periods ended September 30, 2001.


DISCONTINUED OPERATIONS

In December 2001, the Company began accounting for its engineering business
as a discontinued operation. This business was sold effective November 1, 2002.

LIQUIDITY AND CAPITAL RESOURCES (CONTINUED)

The Company's expenditures for property additions were approximately $26.3
million for the first nine months of 2002. Expenditures for property additions
during the remainder of 2002 are anticipated to be approximately $7.7 million.

CASH FLOWS FROM OPERATIONS - Net cash from operating activities for the
three, nine and twelve-month periods ended September 30, 2002, when compared to
the same periods of the prior year, increased by $2.5 million, decreased by $5.0
million and decreased by $9.1 million, respectively. The change in operating
cash flows is influenced significantly by changes in the level and cost of gas
in underground storage, changes in accounts receivable and accrued revenue and
other working capital changes. The changes in these accounts are largely the
result of the timing of cash receipts and payments.

CASH FLOWS FROM FINANCING - Net cash from financing activities during the
three, nine and twelve-month periods ended September 30, 2002 increased by $3.0
million, decreased by $10.7 million, and decreased by $8.1 million,
respectively, when compared to the same periods ended September 30, 2001.

During September 2002, the Company issued $30 million of 6.49% unsecured
Senior Notes due 2009. Interest on the Senior Notes is payable semiannually.
The proceeds from the sale were used to redeem $30 million of 6.83% Senior
Notes, which matured on October 1, 2002.
In October 2002, the Company's Board of Directors declared a regular
quarterly cash dividend of $0.125 per share on the Company's common stock. The
dividend is payable on November 15, 2002 to shareholders of record at the close
of business on November 1, 2002.

FUTURE FINANCING - In general, the Company funds its capital expenditure
program and dividend payments with operating cash flows and the utilization of
its short-term credit facilities. When appropriate, the Company will refinance
its short-term debt with long-term debt, common stock or other long-term
financing instruments. On June 25, 2002, the Company entered into a $145
million credit agreement with a group of banks, replacing four lines of credit
totaling $145 million, which were due to expire. The new agreement, all of
which is committed, consists of an $80 million three-year revolver and a $65
million 364-day facility, with a one-year term loan option. On September 30,
2002, $31.6 million of the Company's credit facilities were unused.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS.


LIQUIDITY AND CAPITAL RESOURCES (CONTINUED)

In March 2000, a registration statement on Form S-3 ("registration
statement") filed by the Company and SEMCO Capital Trust I, SEMCO Capital Trust
II and SEMCO Capital Trust III ("Capital Trusts") with the Securities and
Exchange Commission became effective. On September 30, 2002, there was $134
million available under the Company's registration statement for any future
issuances of common stock, preferred stock, trust preferred securities and long
term debt.
The Company's long-term and short-term debt agreements contain restrictive
financial covenants including, among others, maintaining a Fixed Charges
Coverage Ratio (as defined in the agreements) of at least 1.50 and placing
limits on the payment of dividends beyond certain levels. Non-compliance with
these covenants could result in an acceleration of the due dates for the debt
obligations under the agreements. As of September 30, 2002, the Fixed Charges
Coverage Ratio was 1.8 and the Company was in compliance with all of the
covenants in these agreements. The Company has currently projected its
financial covenants for the remaining quarter during 2002, based on the
Company's forecasted operating results for the year, and these forecasted
results indicate that the Company will be able to remain in compliance with all
of its covenants during 2002. However, these projected results are based on a
number of assumptions and factors. If actual results differ from management's
current expectations, they could have an adverse impact on the Company's ability
to remain in compliance with its covenants during 2002. In the event the
Company is not able to remain in compliance with these covenants, management
plans to request a modification of the covenants or a waiver of certain covenant
provisions. For additional information concerning the factors impacting
compliance with the Company's debt covenants refer to the Management Discussion
and Analysis - Liquidity and Capital Resources section in the Company's 2001
Annual Report on Form 10-K.
The Company's ratio of earnings to fixed charges, as defined under Item 502
of SEC Regulation S-K, was 1.21 for the twelve months ended September 30, 2002.
If common stock of the Company had been issued in place of the FELINE PRIDES,
the ratio of earnings to fixed charges would have been 1.52. This ratio is more
strictly defined than the Fixed Charges Coverage Ratio used to determine
compliance with the Company's previously discussed debt covenants.
Two of the Company's securities, 10.1 million FELINE PRIDES securities and
$105 million of 8.95% Remarketable or Redeemable Securities ("ROARS") are
subject to remarketing, rate resets or possible redemption in 2003. These
securities are described in Note 5 of the Notes to the Consolidated Financial
Statements in the Company's 2001 Annual Report on Form 10-K.
Each FELINE PRIDE consist of a stock purchase contract of the Company and a
9% trust preferred security of SEMCO Capital Trust II with a stated face value
per security of $10 ("9% TPS"). Under the terms of each stock purchase
contract, the FELINE PRIDES holder is obligated to purchase, and the Company is
obligated to sell, a certain number of shares of Company common stock in August
2003. FELINE PRIDES holders can settle their obligation to purchase Company
common stock by paying cash or by having their 9% TPS remarketed in August 2003.
The distribution rate on the 9% TPS will also be reset in August 2003. However,
the Company may limit the reset rate to be no higher than the rate on the
two-year benchmark treasury plus 200 basis points.
In the case of FELINE PRIDES holders who decide to have their 9% TPS
remarketed, $10 of the proceeds from remarketing each 9% TPS will automatically
be applied to satisfy in full the obligation to purchase Company common stock
under the related stock purchase contract. If the remarketing agent is unable
to remarket the 9% TPS at the reset rate, as described above, the Company may
exercise its right as a secured party to dispose of the 9% TPS in accordance
with the provisions of the FELINE PRIDES, in order to satisfy any unfulfilled
obligation to purchase common stock under the related stock purchase contract.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
RESULTS OF OPERATIONS.


LIQUIDITY AND CAPITAL RESOURCES (CONTINUED)

In conjunction with the sale of the ROARS in June 2000, the Company entered
into a remarketing agreement with Banc of America Securities, LLC ("BAS") under
which BAS has the option to purchase all of the ROARS in July 2003, at 100% of
the aggregate principal amount of the ROARS. If BAS elects to purchase the
ROARS in July 2003 and the Company does not exercise its right to elect a
floating interest rate or its right to redeem the ROARS, both of which are
discussed below, BAS will remarket the ROARS at a new fixed interest rate. The
new fixed interest rate would be equal to the sum of 6.5% (the "Base Rate") and
an applicable spread. Under the terms of the ROARS, the applicable spread is
defined as the lowest bid received by BAS from various leading dealers of
publicly traded debt securities, expressed as a spread above the Base Rate and
based on a purchase price equal to the Dollar Price of the ROARS. The Dollar
Price of the ROARS is defined as the present value, at the remarketing date in
July 2003, of the remaining scheduled payments of principle and interest through
maturity in July 2008 calculated at the Base Rate, discounted to the remarketing
date in July 2003 using the rate on U.S. treasury securities with maturities
comparable to the remaining term of the ROARS.
If BAS elects to purchase the ROARS in July 2003, the Company will have the
right to elect that BAS remarket the ROARS for a period of up to one year using
a floating interest rate ("Floating Rate Period") rather than the fixed interest
rate described above. At the end of the Floating Rate Period, BAS can elect to
purchase the ROARS to remarket at a new fixed interest rate as described above.
If BAS elects to purchase the ROARS for remarketing in July 2003 or at the
end of the Floating Rate Period, the Company will also have the right to redeem
the ROARS directly from BAS at either time at the Dollar Price as defined above.
If BAS does not elect to purchase the ROARS in July 2003, the Company is
required to redeem all of the ROARS at that time at 100% of the aggregate
principal amount of the ROARS. If BAS does not elect to purchase the ROARS at
the end of the Floating Rate Period, the Company is required to redeem all of
the ROARS at the Dollar Price.
