1. BACKGROUND AND BASIS OF PRESENTATION
 
BACKGROUND
 
    CommScope, Inc. ("CommScope" or the "Company") was incorporated in Delaware
in January 1997 and, through its wholly owned subsidiary CommScope, Inc. of
North Carolina, formerly a wholly-owned subsidiary of General Instrument
Corporation ("General Instrument"), operates in the cable manufacturing
business. The Company designs, manufactures and markets coaxial, fiber optic and
high performance electronic cables primarily used in communications, local area
network, aerospace and industrial applications. CommScope is the largest
manufacturer and supplier of coaxial cable for cable television applications in
the United States and is a leading supplier of coaxial cable for satellite
television applications. CommScope is also a major supplier of coaxial cable to
international cable television markets.
 
    General Instrument (i) transferred all the assets and liabilities relating
to the manufacture and sale of broadband communications products used in the
cable television, satellite, and telecommunications industries to its
wholly-owned subsidiary NextLevel Systems, Inc. ("NextLevel Systems") and all
the assets and liabilities relating to the manufacture and sale of coaxial,
fiber optic and other electronic cable used in the cable television, satellite
and other industries to CommScope, Inc. (then a wholly-owned subsidiary of
General Instrument) and (ii) distributed all of the outstanding shares of
capital stock of each of NextLevel Systems and CommScope to its stockholders on
a pro rata basis as a dividend in a transaction that was consummated on July 28,
1997. Approximately 147.3 million shares of NextLevel Systems Common Stock,
based on an exchange ratio of one for one, were distributed to General
Instrument's stockholders of record on July 25, 1997 (the "NextLevel
Distribution"). On the Distribution Date, approximately 49.1 million shares of
CommScope Common Stock, based on an exchange ratio of one for three, were
distributed to NextLevel Systems' stockholders of record on that date (the
"CommScope Distribution" and together with the NextLevel Distribution,
collectively the "Distribution"). On the Distribution Date, NextLevel Systems
and CommScope began operating as independent entities with publicly traded
common stock. General Instrument retained no ownership interest in either
NextLevel Systems or CommScope. Additionally, following the NextLevel
Distribution, General Instrument was renamed General Semiconductor, Inc.
("General Semiconductor") and effected a one for four reverse stock split.
 
    For the purpose of governing certain of the ongoing relationships among
NextLevel Systems, CommScope and General Semiconductor after the Distribution
and to provide mechanisms for an orderly transition, NextLevel Systems,
CommScope and General Semiconductor have entered into various agreements which
the companies believe are fair to each of the parties and are comparable to
those which would have been reached in arm's length negotiations with
unaffiliated parties.
 
BASIS OF PRESENTATION
 
    The accompanying interim condensed consolidated financial statements reflect
the results of operations, financial position, and cash flows of CommScope that
were transferred from General Instrument to the Company in connection with the
Distribution. The condensed consolidated balance sheet as of June 30, 1997, the
condensed consolidated statements of income for the three months and the six
months ended June 30, 1997 and 1996, and the condensed consolidated statements
of cash flows for the six months ended June 30, 1997 and 1996 are unaudited and
reflect all adjustments of a normal recurring nature which are, in the opinion
of management, necessary for a fair presentation of the interim period financial
statements. There were no adjustments of a non-recurring nature recorded during
the three and six months ended

1. BACKGROUND AND BASIS OF PRESENTATION (CONTINUED)
June 30, 1997 and 1996. The results of operations for the interim period are not
necessarily indicative of the results of operations to be expected for the full
year.
 
    The unaudited interim condensed consolidated financial statements of
CommScope have been prepared pursuant to the rules and regulations of the
Securities and Exchange Commission. Accordingly, certain information and
footnote disclosures normally included in financial statements prepared in
accordance with generally accepted accounting principles have been condensed or
omitted.
 
    The condensed consolidated financial statements include an allocation of
certain assets, liabilities and general corporate expenses from General
Instrument, and accordingly reflect the results of operations and changes in
cash flows of the Company as if it were a separate entity prior to the
Distribution. In the opinion of management, general corporate administrative
expenses have been allocated to CommScope on a reasonable and consistent basis
using management's estimate of services provided to CommScope by General
Instrument. However, such allocations are not necessarily indicative of the
level of expenses which might have been incurred had CommScope been operating as
a separate, stand-alone entity during the periods presented.
 
    Prior to the Distribution Date, CommScope participated in General
Instrument's cash management program, and the accompanying financial statements
include an allocation of net interest expense from General Instrument. Net
interest expense has been allocated based upon CommScope's net assets as a
percentage of the total net assets of General Instrument. The allocations were
made consistently in each period, and management believes the allocations are
reasonable. However, these interest costs would not necessarily be indicative of
what the actual costs would have been had CommScope operated as a separate,
stand-alone entity during the periods presented.
 
    Subsequent to the Distribution, CommScope will be responsible for the cash
management functions using its own resources or purchased services and will be
responsible for the costs associated with operating a public company.
 
    CommScope's financial results include the costs incurred by General
Instrument related to the postretirement benefit plan for employees and retirees
of CommScope. Also, the provision for income taxes for the six months ended June
30, 1997 and 1996 is based on CommScope's expected annual effective tax rate,
calculated assuming CommScope had filed separate tax returns under its
previously existing structure as a wholly-owned subsidiary of General
Instrument.
 
    The financial information included herein does not necessarily reflect the
consolidated results of operations, financial position, and cash flows of
CommScope in the future or on a historical basis had CommScope been a separate
stand-alone entity for the periods presented. These interim condensed
consolidated financial statements should be read in conjunction with the
Company's December 31, 1996 audited consolidated financial statements and notes
thereto included in the Company's Prospectus dated June 13, 1997.
 
    No historical earnings per share data is presented as the CommScope earnings
were part of General Instrument's results for all periods presented and until
the Distribution Date.

3. PRO FORMA FINANCIAL INFORMATION AND SUBSEQUENT CAPITAL STRUCTURE
 
    The accompanying unaudited pro forma consolidated statements of income
present the consolidated results of CommScope and were prepared to give effect
to the Distribution as if it had occurred on January 1, 1996. The unaudited pro
forma statements of income set forth below do not purport to represent what
CommScope's operations actually would have been or to project CommScope's
operating results for any future period.
 
    The unaudited pro forma information has been prepared utilizing the
historical consolidated statements of income of CommScope which were adjusted to
reflect a net debt level of $275 million at the beginning of each period
presented at an assumed weighted average borrowing rate of 6.35% plus the
amortization of debt issuance costs associated with the new borrowings (see
discussion following the pro forma statements of income). Pro forma earnings per
share was calculated by dividing the pro forma net income for each period
presented by the pro forma common and common equivalent shares outstanding for
each period, and assumes that the total of 49.2 million common and common
equivalent shares outstanding at the Distribution Date were outstanding since
January 1, 1996.
 
    Giving effect to the Distribution as of January 1, 1996, pro forma results
for the Company would have been as follows:

    Giving effect to the Distribution as of June 30, 1997, the Company's pro
forma net debt was $275 million and total stockholders' equity was approximately
$140 million.
 
    On July 23, 1997, prior to the Distribution, the Company entered into a $350

million under the Credit Agreement which was utilized to make a dividend payment
to General Instrument in accordance with the terms of the Distribution and to
fund fees and expenses in connection with the Credit Agreement. The Company
intends to utilize the Credit Agreement in the future for, among other things,
general working capital needs, financing strategic acquisitions, and other
general corporate purposes.
 
    The Credit Agreement provides a total of $350 million in available revolving
credit commitments through loans available at various interest rates and
interest maturity periods (collectively, the "Revolving Credit Loans") and
through the issuance of standby or commercial letters of credit ("Letters of
Credit") of up to $50 million. All amounts borrowed under the Credit Agreement
are due on December 31, 2002.
 
    At the Company's option, advances under the Revolving Credit Loans are
available by choosing from one of the following types of loans, which are
primarily differentiated by the interest rates available: (i) an ABR Loan (as
defined in the Credit Agreement), with interest based on the highest of the
prime rate of The Chase Manhattan Bank, the Base CD Rate (as defined in the
Credit Agreement) plus 1%, or the Federal Funds Effective Rate (as defined in
the Credit Agreement) plus 0.5%; (ii) a Eurodollar Loan (as defined in the
Credit Agreement), with interest based on the Eurodollar Rate (LIBOR) plus a
margin which will vary based on the Company's performance with respect to
certain calculated financial ratios as defined in the Credit Agreement; (iii) an
Absolute Rate Bid Loan (as defined in the Credit Agreement), with interest
determined through competitive bid procedures among qualified lenders under the
Credit Agreement; and (iv) a Swing Line Loan (as defined in the Credit
Agreement) for up to an aggregate amount of $30 million, with interest based on
a money market rate, the ABR Loan rate or a combination thereof.
 
    Interest on the Revolving Credit Loans generally is payable quarterly in
arrears or, for a Eurodollar Loan, at the end of an interest period date which
is specified at the time funds are advanced to the Company, not to exceed three
months. A facility fee based on the total commitment under the Credit Agreement
and a fee for outstanding letters of credit is payable quarterly.
 
    The Credit Agreement contains certain financial and operating covenants,
including restrictions on incurring indebtedness and liens, entering into
transactions to acquire or merge with any entity, making certain other
fundamental changes, selling assets, paying dividends, and maintaining certain
minimum levels of consolidated net worth, leverage ratio, and interest coverage
ratios.
 
4. SUBSEQUENT EVENTS
 
    In July 1997, Vision Cables Pty. Ltd. ("Vision Cables"), an Australian
company in which CommScope owns a 49% minority interest, announced to its
workforce that it plans to suspend manufacturing operations at its facility near
Melbourne, Australia in August of this year. The joint venture company was
established in 1995 with Pacific Dunlop Ltd. of Australia ("Pacific Dunlop"),
the 51% owner. Vision Cables has been supplying the Australian cable television
market with both CommScope manufactured coaxial cables imported from the United
States and coaxial cables produced by Vision Cables in Australia.
 
    CommScope and Pacific Dunlop are together evaluating options for future
manufacturing operations at the Melbourne facility. If the manufacturing
operations are permanently discontinued, CommScope may

need to record its minority interest share of the one-time charges related to
the closing of $1 million to $3 million after tax ($0.02 to $0.06 per share) as
early as the third quarter of 1997.
 
    The Company's share of the net income or loss of the joint venture is
included in the consolidated statements of income using the equity method of
accounting. Since 1995, CommScope has recorded net income of approximately $1
million, after tax, from its minority interest investment in the joint venture
and sold approximately $50 million of CommScope exported products to the
Australian market through the Vision Cables distribution arrangement.
 
    In August 1997, the Company announced that it had reached a non-binding
understanding with Alcatel Cable France ("Alcatel") that would establish a
European base of operations for CommScope.
 
    The tentative agreement centers around a transfer by Alcatel to CommScope of
its CATV coaxial cable business in Seneffe, Belgium. Alcatel would also purchase
its future requirements of CATV coaxial cable from CommScope for a period of
time to be determined. As a part of the arrangement, Alcatel would receive
substantially all of the assets from CommScope's high-temperature aerospace and
industrial cable business in Elm City, North Carolina.
 
    The agreement is subject to certain contingencies including board approval
by both companies, regulatory approval and due diligence, and is expected to be

    Sales from Alcatel's Seneffe coaxial cable business were approximately $20

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF RESULTS OF OPERATIONS AND
  FINANCIAL POSITION
 
    The following discussion and analysis is provided to increase the
understanding of, and should be read in conjunction with, the unaudited
condensed consolidated financial statements and accompanying notes included in
this document as well as the audited consolidated financial statements, related
notes thereto and management's discussion and analysis of results of operations
and financial position for the year ended December 31, 1996 included in the
Company's Prospectus dated June 13, 1997. Unless otherwise specified,
capitalized terms used herein are used as defined in the audited consolidated
financial statements of CommScope for the year ended December 31, 1996.
 
HIGHLIGHTS
 
    CommScope reported net income of $13 million for the quarter ended June 30,
1997, unchanged from the second quarter of 1996. For the six months ended June
30, 1997, net income increased 6% to $27 million, compared to $25 million for
the same period in 1996. No historical earnings per share data is presented as
the CommScope earnings were part of General Instrument's results for all periods
presented.
 
    CommScope reported pro forma net income of $12 million ($0.24 per pro forma
share) for the quarter ended June 30, 1997, unchanged from the second quarter of
1996. For the six months ended June 30, 1997 pro forma net income was $25
million ($0.50 per pro forma share), compared to $23 million ($0.46 per pro
forma share) for the same period in 1996, an increase of 8%. Pro forma net
income and earnings per share reflect the impact of CommScope's new capital
structure immediately following the Distribution (see Liquidity and Capital
Resources below), assuming that all common stock issued and long term debt
borrowings as of the Distribution Date were outstanding since January 1, 1996.
 
             COMPARISON OF RESULTS OF OPERATIONS FOR THE THREE AND
            SIX MONTH PERIODS ENDED JUNE 30, 1997 WITH THE THREE AND
                     SIX MONTH PERIODS ENDED JUNE 30, 1996
 
NET SALES
 
    Net sales for the second quarter and six months ended June 30, 1997
increased $17 million (12%) to $159 million and $34 million (13%) to $307
million, respectively, over the comparable prior year periods. This increase in
net sales reflects higher sales in cable television and other video distribution
markets and strong growth in the local area network ("LAN") product line.
 
    Net sales to cable television and other video distribution markets for the
second quarter and six months ended June 30, 1997 increased $11 million (9%) to
$135 million and $17 million (7%) to $256 million, respectively, over the
comparable prior year periods, primarily due to higher sales volume of both
semi-flexible coaxial cables used in the trunk and feeder distribution portion
of cable television systems and flexible coaxial (drop) cable primarily used for
connecting the feeder cable to the cable television subscriber's residence.
These sales have been driven by increased deployment of hybrid fiber coaxial
("HFC") networks for new cable television systems in international markets and
continued domestic growth, offset in part by a slow down in such spending by a
major cable television operator in the United States.
 
    Net sales for LAN and other data applications for the second quarter and six
months ended June 30, 1997 increased $3 million (19%) to $17 million and $8
million (27%) to $37 million, respectively, over the comparable prior year
periods, reflecting higher sales volume for premise wiring of LANs. Partially
offsetting the volume increases for cable television and LAN products were
decreases in the average selling prices of these products.
 
    Sales of other cable products for the second quarter and six months ended
June 30, 1997 were $7 million and $14 million, respectively, compared to $3
million and $5 million, respectively, for the second quarter and six months
ended June 30, 1996. This increase is primarily due to sales of high-temperature
 
                                       11
<PAGE>
aerospace and industrial cable products from the Company's Elm City, North
Carolina facility, which was acquired along with certain other assets of the
Thermatics Division of Teledyne Industries, Inc. in May 1996. Sales of
high-temperature aerospace and industrial cable products for the three and six
months ended June 30, 1997 were $4 million and $8 million, respectively,
compared with sales for the month of June 1996, subsequent to the acquisition of
the Elm City facility, of $1 million.
 
    International sales for the second quarter and six months ended June 30,
1997 increased $9 million (20%) to $57 million and $19 million (21%) to $111
million, respectively, over the comparable prior year periods. International
sales for the six months ended June 30 represented 36% of the Company's net
sales in 1997 compared to 33% in 1996.
 
GROSS PROFIT (NET SALES LESS COST OF SALES)
 
    Gross profit for the second quarter and six months ended June 30, 1997 was
$39 million and $79 million, respectively, compared to $37 million and $71
million for the comparable prior year periods, an increase of 7% and 11%,
respectively. The higher gross profit reflects the increased sales volume noted
above and lower overhead costs including reduced warranty related provisions due
to lowered expectations of claims, partially offset by the lower average selling
prices described above and increases in raw material costs. As a percentage of
sales, gross margin declined from 26% in the second quarter of 1996 to 25% for
the second quarter of 1997. For both the six months ended June 30, 1997 and 1996
gross margin as a percentage of sales was 26%. Due to the competitive pricing
environment and higher raw material costs, the Company expects gross margins
percentages to range from 23% to 25% for the remainder of fiscal 1997.
 
SELLING, GENERAL AND ADMINISTRATIVE
 
    SG&A expense for the second quarter and six months ended June 30, 1997
increased $2 million (23%) to $13 million and $4 million (21%) to $25 million,
respectively, over the comparable prior year periods. As a percentage of sales,
SG&A expense for the second quarters ended June 30, 1997 and 1996 was 8%, and
for the six month periods ended June 30, 1997 and 1996 was 8% and 7%,
respectively. The increase in SG&A expense was principally attributable to
increased sales and marketing expenditures to support product expansion and
increased growth opportunities in international cable and network markets.
 
RESEARCH AND DEVELOPMENT
 
    Research and development expense as a percentage of sales was unchanged for
the second quarter and six months ended June 30, 1997 compared with the
corresponding periods in 1996. The Company has ongoing programs to develop new
products and market opportunities for its products and core capabilities and new
manufacturing technologies to achieve cost reductions.
 
INTEREST EXPENSE-NET
 
    Net interest expense represents an allocation of interest expense from
General Instrument and was allocated based upon the Company's net assets as a
percentage of the total net assets of General Instrument. Net interest expense
allocated to the Company was $3 million and $5 million for the quarter and six
months ended June 30, 1997, respectively, unchanged from the corresponding
periods of 1996.
 
    Pro forma net interest expense reflects the historical interest expense of
the Company adjusted to reflect a net debt level of $275 million at the
beginning of each period presented at an assumed weighted average borrowing rate
of 6.35% for each period plus the amortization of debt issuance costs associated
with the new borrowings (see Liquidity and Capital Resources below). These pro
forma net interest costs are not necessarily indicative of what the actual
interest costs would have been had CommScope operated as a separate, stand-alone
entity.

INCOME TAXES
 
    The provision for income taxes has been determined as if the Company had
filed separate tax returns under its previously existing structure as a wholly
owned subsidiary of General Instrument for the periods presented. Accordingly,
future tax rates could vary from the historical effective tax rates depending on
the Company's future tax elections.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    Cash provided by operations was $23 million for the six months ended June
30, 1997 compared to $25 million for the comparable prior year period, a
decrease of $2 million or 10%. This decrease is primarily attributable to
increases in net working capital due to sales growth partially offset by the
increase in net income in 1997 over the comparable six month period in 1996.
 
    Working capital was $122 million at June 30, 1997 compared to $107 million
at December 31, 1996, an increase of $15 million, or 14%. The increase in
working capital is due to an increase in sales volume with a corresponding
increase in accounts receivable as well as increased inventory to support
business growth and the introduction of new products, partially offset by the
related increases in accounts payable. Based on current levels of orders and
backlog, management of the Company believes that working capital levels are
appropriate to support future operations.
 
    During the six months ended June 30, 1997, the Company invested $19 million
in equipment and facilities compared to $9 million for the comparable period in
1996. This level of capital spending was attributable to capacity expansion
across the business units of the Company to meet increased current and
anticipated future demands. During the six months ended June 30, 1996, the
Company utilized $18 million to acquire certain assets of the Thermatics
Division of Teledyne Industries, Inc.
 
    Management of the Company assesses its liquidity in terms of its overall
ability to obtain cash to support its ongoing business levels and to fund its
growth objectives. Prior to the Distribution Date, the Company participated in
the General Instrument cash management program. To the extent the Company
generated positive cash, such amounts were remitted to General Instrument. To
the extent the Company experienced temporary cash needs for working capital
purposes or capital expenditures, such funds historically were provided by
General Instrument. The net effect of these transactions is included in
additional paid-in capital as transfers from / to sole stockholder. Effective as
of the Distribution Date, the Company has independently established a cash
management program to support future business levels and growth objectives.
 
    The Company's principal sources of liquidity both on a short-term and
long-term basis have been cash flows provided by operations and funds provided
by General Instrument. Net cash transfers to General Instrument were $3 million
for the six months ended June 30, 1997 compared to net cash transfers from
General Instrument to the Company of $2 million for the six months ended June
30, 1996. Management believes that, based upon its analysis of the Company's
consolidated financial position and the expected results of its operations in
the future, the Company will have sufficient cash flows from future operations
and the financial flexibility to attract both short- and long-term capital on
acceptable terms as may be needed to fund operations, capital expenditures and
its other growth objectives. There can be no assurance, however, that future
industry-specific developments or general economic trends will not adversely
affect the Company's operations or its ability to meet its cash requirements.
 
    On July 23, 1997, prior to the Distribution, the Company entered into a $350
million credit agreement with a group of banks (the "Credit Agreement"). On the
Distribution Date, the Company borrowed $266 million under the Credit Agreement
which was utilized to make a dividend payment to General Instrument in
accordance with the terms of the Distribution and to fund fees and expenses in
connection with the Credit Agreement. The Company intends to utilize the Credit
Agreement in the future for, among other
 
                                       13
<PAGE>
things, general working capital needs, financing strategic acquisitions, and
other general corporate purposes.
 
    The Credit Agreement provides a total of $350 million in available revolving
credit commitments through loans available at various interest rates and
interest maturity periods (collectively, the "Revolving Credit Loans") and
through the issuance of standby or commercial letters of credit ("Letters of
Credit") of up to $50 million. All amounts borrowed under the Credit Agreement
are due on December 31, 2002.
 
    At the Company's option, advances under the Revolving Credit Loans are
available by choosing from one of the following types of loans, which are
primarily differentiated by the interest rates available: (i) an ABR Loan (as
defined in the Credit Agreement), with interest based on the highest of the
prime rate of The Chase Manhattan Bank, the Base CD Rate (as defined in the
Credit Agreement) plus 1%, or the Federal Funds Effective Rate (as defined in
the Credit Agreement) plus 0.5%; (ii) a Eurodollar Loan (as defined in the
Credit Agreement), with interest based on the Eurodollar Rate (LIBOR) plus a
margin which will vary based on the Company's performance with respect to
certain calculated financial ratios as defined in the Credit Agreement; (iii) an
Absolute Rate Bid Loan (as defined in the Credit Agreement), with interest
determined through competitive bid procedures among qualified lenders under the
Credit Agreement; and (iv) a Swing Line Loan (as defined in the Credit
Agreement) for up to an aggregate amount of $30 million, with interest based on
a money market rate, the ABR Loan rate or a combination thereof.
 
    Interest on the Revolving Credit Loans generally is payable quarterly in
arrears or, for a Eurodollar Loan, at the end of an interest period date which
is specified at the time funds are advanced to the Company, not to exceed three
months. A facility fee based on the total commitment under the Credit Agreement
and a fee for outstanding letters of credit is payable quarterly.
 
    The Credit Agreement contains certain financial and operating covenants,
including restrictions on incurring indebtedness and liens, entering into
transactions to acquire or merge with any entity, making certain other
fundamental changes, selling assets, paying dividends, and maintaining certain
minimum levels of consolidated net worth, leverage ratio, and interest coverage
ratios.
 
    Giving effect to the Distribution as of June 30, 1997, the Company's pro
forma net debt was $275 million and total stockholders' equity was approximately
$140 million.
