Item 1. Financial Statements

The accompanying unaudited consolidated financial statements have been prepared
in accordance with the requirements of Form 10-Q and, therefore, do not include
all information and footnotes required by accounting principles generally
accepted in the United States. However, in our opinion, all adjustments,
consisting only of normal recurring accruals, necessary for a fair presentation
of the results of operations for the relevant periods have been made. Results
for the interim periods are not necessarily indicative of the results to be
expected for the year. These financial statements should be read in conjunction
with the summary of significant accounting policies and the notes to the
consolidated financial statements included in our Annual Report on Form 10-K for
the year ended December 31, 2000.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization and Basis of Presentation

We were formed in September 1999 to serve as the holding company and a financing
vehicle for Insight Communications Company, Inc.'s ("Insight Inc.") cable
television system joint venture with AT&T Broadband, LLC ("AT&T Broadband"). We
are owned 50% by Insight Communications Company, L.P. ("Insight LP"), which is
wholly-owned by Insight Inc., and 50% by AT&T Broadband, through its indirect
subsidiary TCI of Indiana Holdings, LLC ("TCI").

The accompanying consolidated financial statements include the accounts of our
subsidiaries that own and operate cable television systems in Illinois, Indiana,
Kentucky, Ohio and Georgia.

2. Responsibility for Interim Financial Statements

Our accompanying unaudited consolidated financial statements have been prepared
in accordance with accounting principles generally accepted in the United States
for interim financial information and with the instructions to Form 10-Q and
Article 10 of Regulation S-X. Accordingly, they do not include all of the
information and footnote disclosures required by accounting principles generally
accepted in the United States for complete financial statements.

In our opinion, the consolidated financial statements reflect all adjustments
considered necessary for a fair statement of the consolidated results of
operations and financial position for the interim periods presented. All such
adjustments are of a normal recurring nature. These unaudited interim
consolidated financial statements should be read in conjunction with the audited
consolidated financial statements and notes to consolidated financial statements
contained in our Annual Report on Form 10-K for the year ended December 31,
2000.

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires us 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. The results
of operations for the three months ended March 31, 2001 are not necessarily
indicative of the results to be expected for the year ending December 31, 2001
or any other interim period.

Certain 2000 amounts have been reclassified to conform to the 2001 presentation.

3. Cable System Transactions

On January 5, 2001, we completed a series of transactions with Insight LP and
certain subsidiaries of AT&T Corp. (the "AT&T Cable Subsidiaries") for the
acquisition of additional cable television systems, primarily located in the
state of Illinois, valued at approximately $2.2 billion (the "AT&T
Transactions"), inclusive of systems valued at approximately $775.8 million,
contributed by Insight LP. The AT&T Transactions were financed through a credit
facility established on January 5, 2001, the Midwest Holdings Credit Facility
(Note 6). As a result of the AT&T Transactions, we acquired all of Insight LP's
wholly-owned systems serving approximately 280,000 customers, including systems
which Insight LP purchased from the AT&T Cable Subsidiaries. At the same time,
we acquired from the AT&T Cable Subsidiaries systems serving approximately
250,000 customers. The purchase price was preliminarily allocated to the cable
television assets acquired in relation to their estimated fair values as
increases to franchise rights. The purchase price allocation will be finalized
upon completion and receipt of appraisal reports.

Both Insight LP and the AT&T Cable Subsidiaries contributed their respective
systems to us subject to an amount of indebtedness such that we remain equally
owned by Insight LP and AT&T Broadband. Insight LP continues to serve as our
general partner and manages and operates our systems. As a result of the AT&T
Transactions, we currently own and operate cable television systems in Indiana,
Kentucky, Illinois, Ohio and Georgia which passed approximately 2.2 million
homes and served approximately 1.3 million customers as of March 31, 2001.

As a result of the AT&T Transactions, the financial results of Insight Ohio are
consolidated into our financial statements effective January 1, 2001. For
financing purposes, Insight Ohio is an unrestricted subsidiary under our
indentures and is prohibited by the terms of its indebtedness from making
distributions to us.

On January 11, 2001, we acquired Cable One, Inc.'s, Greenwood, Indiana cable
television system serving approximately 14,800 customers for $62.0 million. The
purchase price was allocated to the cable television assets acquired in relation
to their fair values as increases in property and equipment and franchise
rights.

6. Debt (continued)

Insight Ohio Credit Facility

On January 5, 2001, in connection with the AT&T Transactions, we acquired
Insight Ohio and the existing debt of Insight Ohio. Insight Ohio's credit
facility (the "Ohio Credit Facility") provides for revolving credit loans of up
to $25.0 million. The Ohio Credit Facility has a six-year maturity from the date
of borrowings, with reductions to the amount of the commitment commencing after
three years. Our obligations under the Ohio Credit Facility are secured by
substantially all the assets of Insight Ohio. The Ohio Credit Facility requires
Insight Ohio to meet certain financial and other debt covenants. Loans under the
Ohio Credit Facility bear interest, at our option, at the prime rate or at a
Eurodollar rate. In addition to the index rates, we pay an additional margin
percentage tied to Insight Ohio's ratio of total debt to adjusted annualized
operating cash flow.

Insight Midwest Holdings Credit Facility

On January 5, 2001, through a wholly-owned subsidiary ("Insight Midwest
Holdings") which holds all of our cable television systems other than the Ohio
System, we entered into a credit facility (the "Midwest Holdings Credit
Facility") to finance the AT&T Transactions and to repay the outstanding
indebtedness under the Indiana and Kentucky Credit Facilities. The Midwest
Holdings Credit Facility expires in 2009 and provides for maximum borrowings of
$1.75 billion. Obligations under this credit facility are secured by a pledge of
the outstanding equity interests of Midwest Holdings and its subsidiaries.

The Midwest Holdings Credit Facility requires Insight Midwest Holdings to meet
certain financial and other debt covenants. Borrowings under this credit
facility bear interest at either an alternative base rate or Eurodollar rate,
plus an additional margin yield to Insight Midwest Holdings' leverage ratio, of
between 0.5% and 2.75%.

As a result of the repayment of the Indiana and Kentucky Credit Facilities on
January 5, 2001, we recorded an extraordinary charge of $10.3 million related to
the write-off of unamortized deferred financing costs related to these credit
facilities.

Interest Rate Swap and Collar Agreements

In June 1999, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 133, "Accounting for Derivative Instruments
and Hedging Activities" ("SFAS No. 133"). SFAS No. 133, as amended by SFAS No.
137, was adopted as of January 1, 2001. SFAS No. 133 establishes accounting and
reporting standards for derivative instruments embedded in other contracts and
for hedging activities. SFAS No. 133 requires us to recognize all derivatives on
the balance sheet at fair value.

On January 1, 2001, our derivative financial instruments, which were obtained to
manage our exposure to interest rate risk, included interest rate swap and
collar agreements, which qualified as cash flow hedges. On January 1, 2001, we
recorded as a component of other comprehensive income a $1.9 million transition
adjustment loss representing the cumulative effect of adopting SFAS No. 133.
Changes in the fair value of such cash flow hedges are recognized in
stockholders' equity as a component of comprehensive income. For the three
months ended March 31, 2001, the change in the fair value (loss) was $(9.8)
million.

7. Comprehensive Income

Statement of Financial Accounting Standards No. 130, "Reporting Comprehensive
Income" ("SFAS No. 130"), sets forth rules for the reporting and display of
comprehensive income (net income plus all other changes in net assets from
non-owner sources) and its components in the financial statements. For the three
months ended March 31, 2001, components of other comprehensive income consisted
of interest rate swaps of $11.7 million, including the transition adjustment
loss mentioned above. For the three months ended March 31, 2000, there were no
components of other comprehensive income.

8. Related Party Transactions

We purchase substantially all of our pay television and other programming from
affiliates of AT&T Broadband. Charges for such programming were $30.2 million
and $13.6 million for the three months ended March 31, 2001 and 2000. As of
March 31, 2001 and December 31, 2000, $23.6 million and $9.8 million of accrued
programming costs were due to affiliates of AT&T Broadband. We believe that the
programming rates charged by the affiliates of AT&T Broadband are lower than
those available from independent parties.

9. Commitments and Contingencies

Litigation

Insight Kentucky and certain prior owners of the Kentucky Systems have been
named in class actions regarding the pass-through of state and local property
tax charges to customers by the prior owners of the Kentucky Systems. The
plaintiffs seek monetary damages and the enjoinment of the collection of such
taxes. We believe that the Kentucky Systems have substantial and meritorious
defenses to these claims.

We are subject to various legal proceedings that arise in the ordinary course of
business. While it is impossible to determine with certainty the ultimate
outcome of these matters, it is our opinion that the resolution of these matters
will not have a material adverse affect on our consolidated financial condition.

                            NOTES TO BALANCE SHEETS

1. Nature of Business

Insight Capital, Inc. (the "Company"), a Delaware corporation, was formed on
September 23, 1999, for the sole purpose of being a co-issuer of the senior
notes described in Note 3, which allows certain investors the ability to be
holders of the debt. The Company has no operations. The outstanding shares of
the Company are owned by Insight Midwest, L.P. ("Insight Midwest").

2. Responsibility for Interim Financial Statements

The accompanying unaudited financial statements of the Company have been
prepared in accordance with accounting principles generally accepted in the
United States for interim financial information and with the instructions to
Form 10-Q and Article 10 of Regulation S-X. Accordingly, they do not include all
of the information and footnote disclosures required by accounting principles
generally accepted in the United States for complete financial statements.

In management's opinion, the financial statements reflect all adjustments
considered necessary for a fair statement of the financial position as of the
interim dates presented. These unaudited interim financial statements should be
read in conjunction with the audited financial statements and notes to financial
statements contained in the Company's Annual Report on Form 10-K for the year
ended December 31, 2000.

The preparation of financial statements in conformity with accounting principles
generally accepted in the United States requires the Company 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. Actual results could differ from those estimates.

3. Notes Payable

On October 1, 1999, the Company and Insight Midwest completed a $200.0 million
offering of 9 3/4% senior notes due in October 2009. The proceeds of the
offering were used to repay certain debt of Insight Midwest. Interest payments
on these Senior Notes, which commenced on April 1, 2000, are payable
semi-annually on April 1 and October 1.

In April 2000, Insight Midwest completed an exchange offer pursuant to which the
9 3/4% Senior Notes were exchanged for identical notes registered under the
Securities Act of 1933.

On November 6, 2000, the Company and Insight Midwest completed a $500.0 million
offering of 10 1/2% senior notes due in November 2010. Insight Midwest received
proceeds of $487.5 million, net of an underwriting fee of $5.0 million and a
bond discount of $7.5 million. The proceeds of the offering were used to repay
certain debt of Insight Midwest. Interest payments

3. Notes Payable (continued)

on these Senior Notes, which commence on May 1, 2001, are payable semi-annually
on May 1 and November 1.

In May 2001, Insight Midwest completed an exchange offer pursuant to which the
10 1/2% Senior Notes were exchanged for identical notes registered under the
Securities Act of 1933.

The 9 3/4% Senior Notes and 10 1/2% Senior Notes are redeemable on or after
October 1, 2004 and November 1, 2005, respectively. In addition, Insight Midwest
can redeem up to 35% of the 9 3/4% Senior Notes and 10 1/2% Senior Notes prior
to October 1, 2002 and November 1, 2005, respectively, with the net proceeds
from certain sales of Insight Midwest's equity. Each holder of the Senior Notes
may require redemption of all or part of that holder's notes upon certain
changes of control. All future funding on the Senior Notes, including principal
and interest payments, are dependent upon the operating results of Insight
Midwest. The Senior Notes are general unsecured obligations and are subordinate
to all Insight Midwest's liabilities, the amounts of which were $1.76 billion
and $770.5 million as of March 31, 2001 and December 31, 2000. The Senior Notes
contain certain financial and other debt covenants.

Item 2. Management's Discussion and Analysis of Financial Condition and Results
of Operations

Forward-Looking Statements

Some of the information in this quarterly report contains forward-looking
statements that involve substantial risks and uncertainties. You can identify
these statements by forward-looking words such as "may," "will," "expect,"
"anticipate," "believe," "estimate" and "continue" or similar words. You should
read statements that contain these words carefully because they:

     .    discuss our future expectations;

     .    contain projections of our future results of operations or of our
          financial condition; or

     .    state other "forward-looking" information.

We believe it is important to communicate our expectations to our investors.
However, there may be events in the future that we are not able to accurately
predict or over which we have no control. The risk factors listed in our Annual
Report on Form 10-K for the year ended December 31, 2000, as well as any
cautionary language in this quarterly report, provide examples of risks,
uncertainties and events that may cause our actual results to differ materially
from the expectations we describe in our forward-looking statements. You should
be aware that the occurrence of the events described in these risk factors and
elsewhere in this quarterly report could have a material adverse effect on our
business, operating results and financial condition.

Overview

Because of certain transactions completed over the past year, including the
contribution agreement with the AT&T Cable Subsidiaries and Insight Inc. with
respect to certain Illinois systems discussed below, we do not believe the
discussion and analysis of our historical financial condition and results of
operations below are indicative of our future performance.

On January 5, 2001, we completed a series of transactions with Insight LP and
the AT&T Cable Subsidiaries (the "AT&T Transactions"). As a result of the AT&T
Transactions, additional cable television systems serving approximately 530,000
customers were contributed to us. Specifically, we acquired all of Insight LP's
systems not already owned by us as well as systems which Insight LP purchased
from the AT&T Cable Subsidiaries (comprising in total approximately 280,000
customers). The AT&T Cable Subsidiaries contributed to us systems located in
Illinois serving approximately 250,000 customers. Both Insight LP and the AT&T
Cable Subsidiaries contributed their respective systems to us subject to an
amount of indebtedness so that we remain equally owned by Insight LP and AT&T
Broadband. Insight LP continues to serve as our general partner and manages and
operates our systems.

Results of Operations

Substantially all of our revenues were earned from customer fees for cable
television programming services including premium and pay-per-view services and
ancillary services, such as rental of converters and remote control devices,
installations and from selling advertising. In

                                       14
<PAGE>

addition, we earn revenues from commissions for products sold through home
shopping networks.

The following table is derived for the periods presented from our consolidated
financial statements that are included in this report and sets forth certain
statement of operations data for our consolidated operations.

EBITDA represents earnings before interest, taxes, depreciation and
amortization. Our management believes that EBITDA is commonly used in the cable
television industry to analyze and compare cable television companies on the
basis of operating performance, leverage and liquidity. However, EBITDA is not
intended to be a performance measure that should be regarded as an alternative
to, or more meaningful than, either operating income or net income as an
indicator of operating performance or cash flows as a measure of liquidity, as
determined in accordance with generally accepted accounting principles. EBITDA,
as computed by manangement, is not necessarily comparable to similarly titled
amounts of other companies. Refer to our financial statements, including our
statements of cash flows, which appear elsewhere in this quarterly report.

Three Months Ended March 31, 2001 Compared to Three Months Ended March 31, 2000

Revenues increased $75.6 million to $168.2 million for the three months ended
March 31, 2001 compared to $92.5 million for the three months ended March 31,
2000. The increase in revenues is primarily the result of the cable television
systems contributed in the AT&T Transactions, including the Ohio Systems. The
incremental revenue generated by the cable television systems contributed
approximated $70.0 million, which represents 92.6% of the increase in
consolidated revenue. In addition, the existing systems increased revenues for
digital and high-speed data by $4.6 million, a combined 106.7% growth rate.

                                       15
<PAGE>

Average monthly revenue per customer was $43.80 for the three months ended March
31, 2001 compared to $41.20 for the three months ended March 31, 2000 primarily
reflecting the continued successful rollout of new product offerings in the
Indiana, Kentucky and Ohio markets. Average monthly revenue per customer for
high-speed data and interactive digital video increased to $3.66 for the three
months ended March 31, 2001 compared to $1.81 for the comparable period in 2000.
Excluding the systems acquired in the AT&T Transactions, the number of
high-speed data service customers increased to 39,800 as of March 31, 2001 from
12,400 as of March 31, 2000, while digital customers increased to 136,600 as of
March 31, 2001 from 54,700 as of March 31, 2000.

Programming and other operating costs increased $25.9 million to $54.2 million
for the three months ended March 31, 2001 compared to $28.3 million for the
three months ended March 31, 2000. The increase in programming and other
operating costs is primarily the result of the cable television systems
contributed in the AT&T Transactions. The incremental expense generated by the
contribution of these systems approximated $23.4 million, which represents 90.1%
of the increase in programming and other operating costs. Excluding these
systems, programming and other operating costs increased by approximately $2.6
million or 9.9% primarily as a result of increased programming rates and
additional programming carried by our existing systems.

Selling, general and administrative expenses increased $14.0 million to $34.6
million for the three months ended March 31, 2001 compared to $20.7 million for
the three months ended March 31, 2000. The increase in selling, general and
administrative expenses is primarily the result of the acquisition of the cable
television systems contributed in the AT&T Transactions. The incremental
selling, general and administrative expenses generated by the acquisition of the
Illinois systems approximated $12.9 million, which represents 92.4% of the
increase. Excluding these systems, these costs increased by approximately $1.1
million accounting for approximately 7.6% of the total increase, primarily
reflecting increased marketing activity associated with new product
introductions.

Depreciation and amortization expense increased $39.6 million to $85.8 million
for the three months ended March 31, 2001 compared to $46.1 million for the
three months ended March 31, 2000. The increase in depreciation and amortization
expense is primarily the result of the cable television systems contributed in
the AT&T Transactions. The incremental depreciation and amortization expense
generated by these systems approximated $29.5 million, which represents 74.5% of
the increase. Excluding these systems, depreciation and amortization increased
by approximately $10.1 million or 25.5% primarily due to capital expenditures
made to rebuild the existing cable equipment during previous quarters.

EBITDA increased 56.0% to $63.8 million for the three months ended March 31,
2001 as compared to $40.9 million for the three months ended March 31, 2000 for
the following reasons:

     .    The first full quarter of results generated by the systems contributed
          in the AT&T Transactions and
     .    Offsetting these operating results in 2001 was a $10.3 million
          extraordinary loss recorded during the three months ended March 31,
          2001 due to early extinguishments of debt.

                                       16
<PAGE>

Interest expense increased $21.8 million to $47.8 million for the three months
ended March 31, 2001 compared to $26.0 million for the three months ended March
31, 2000. The increase in interest expense is primarily the result of higher
outstanding debt required by the acquisition of the cable television systems
acquired in the AT&T Transactions and funding of capital expenditures during the
past year.

For the three months ended March 31, 2001, the net loss was $69.3 million for
the reasons set forth above.

Liquidity and Capital Resources

Our business requires cash for operations, debt service, capital expenditures
and acquisitions. The cable television business has substantial on-going capital
requirements for the construction, expansion and maintenance of its broadband
networks. Expenditures have primarily been used to upgrade our existing cable
network, and in the future will be used for network extensions, new services,
converters and network upgrades. Historically, we have been able to meet our
cash requirements with cash flow from operations, borrowings under our credit
facilities, issuances of private equity and accessing other public sources.

For the three months ended March 31, 2001 and March 31, 2000, we spent $62.2
million and $41.4 million in capital expenditures largely to support our plant
rebuild, digital converter purchases and to a lesser extent network extensions.
We will continue to incur capital expenditures particularly for success-based
deployment of new services, including telephony and for the upgrade of the
Illinois cable television systems, which involve the use of fiber optics and
other capital projects associated with implementing our clustering strategy.

On January 5, 2001, in connection with the AT&T Transactions, Insight Midwest
Holdings entered into the $1.75 billion Midwest Holdings Credit Facility from
which it borrowed $663.0 million to repay the Indiana and Kentucky credit
facilities and $685.0 million to finance the AT&T Transactions.

On January 5, 2001, we acquired all of the common equity interests of Insight
Ohio as part of the AT&T Transactions. Insight Ohio is an unrestricted
subsidiary under the indentures governing and our notes, and is prohibited by
the terms of its indebtedness from making distributions to us.

As of March 31, 2001, we had aggregate consolidated indebtedness of $2.10
billion, including $1.40 billion outstanding under senior bank credit
facilities. The senior bank credit facilities consisted of:

     .    $1.75 billion Midwest Holdings Credit Facility maturing in 2009, which
          will be utilized to support Insight Midwest's operations and
          build-out, of which $1.38 billion was borrowed. The remaining
          availability of $370.0 million will be used to support the
          aforementioned capital expenditures; and

     .    $25.0 million Insight Ohio Credit Facility maturing in 2004, which was
          fully-borrowed.

The weighted average interest rate for amounts outstanding under our senior
credit facilities as of March 31, 2001 was 8.0%. The facilities contain
covenants restricting, among other things, our ability to make capital
expenditures, acquire or dispose of assets, make investments and engage

                                       17
<PAGE>

in transactions with related parties. The facilities also require compliance
with certain financial ratios and contain customary events of default. We
believe that our credit facilities and our cash flow from operations are
sufficient to support our current operating plan.

Item 3. Quantitative and Qualitative Disclosure About Market Risk

Our revolving credit and term loan agreements bear interest at floating rates.
Accordingly, we are exposed to potential losses related to changes in interest
rates. We do not enter into derivatives or other financial instruments for
trading or speculative purposes. In order to manage our exposure to interest
rate risk, we enter into derivative financial instruments, typically interest
rate swaps and collars. The counterparties to our swap and collar agreements are
major financial institutions. As of March 31, 2001, our interest rate swap and
collar agreements expire in varying amounts through July 2003.

The fair market value of our long-term debt approximates its carrying value as
the credit facility borrowings bear interest at floating rates of interest and
current fair market value of the senior notes approximates par value. As of
March 31, 2001, the estimated fair value (loss) of our interest rate swap and
collar agreements was approximately $(11.7) million, which represents the amount
required to enter into offsetting contracts with similar remaining maturities
based on quoted market prices and is reflected in our financial statements as
other non-current liabilities. Changes in the fair value of derivative financial
instruments are either recognized in income or in stockholders' equity as a
component of other comprehensive income depending on whether the derivative
financial instruments qualify for hedge accounting.

As of March 31, 2001, we had entered into interest rate swaps that approximated
$625.0 million, or 44.5%, of our borrowings under all of our credit facilities.
Accordingly, a hypothetical 100 basis point increase in interest rates along the
entire interest rate yield curve would increase our annual interest expense by
approximately $7.8 million.
