NOTE 1 - BASIS OF PRESENTATION

         The unaudited consolidated financial statements of Encore Wire
Corporation have been prepared in accordance with generally accepted accounting
principles for interim financial information and the instructions to Form 10-Q
and Rule 10-01 of Regulation S-X. Accordingly, they do not include all of the
information and footnotes required by generally accepted accounting principles
for complete financial statements. In the opinion of management, all
adjustments, consisting only of normal recurring adjustments considered
necessary for a fair presentation, have been included. Results of operations for
interim periods presented do not necessarily indicate the results that may be
expected for the entire year. These financial statements should be read in
conjunction with the audited consolidated financial statements and notes thereto
included in the Company's Annual Report on Form 10-K for the year ended December
31, 2000.

NOTE 2 - INVENTORIES

         Inventories are stated at the lower of cost, determined by the last-in,
first-out (LIFO) method, or market.

         Inventories (in thousands) consisted of the following:

         An actual valuation of inventory under the LIFO method can be made only
at the end of each year based on the inventory levels and costs at that time.
Accordingly, interim LIFO calculations must necessarily be based on management's
estimates of expected year-end inventory levels and costs. Because these are
subject to many forces beyond management's control, interim results are subject
to the final year-end LIFO inventory valuation. The Company did, however, set up
a $1,000,000 lower of cost or market reserve to


                                                                               7

reflect the fact that the LIFO cost basis as currently calculated, exceeded the
current market value by that amount at the end of the first quarter of 2001.

NOTE 3 - INCOME PER SHARE

         Income (loss) per common and common equivalent share is computed using
the weighted average number of shares of common stock and common stock
equivalents outstanding during each period. If dilutive, the effect of stock
options, treated as common stock equivalents, is calculated using the treasury
stock method.

The following table sets forth the computation of basic and diluted earnings per
share:

NOTE 4 - LONG TERM NOTE PAYABLE

         Effective August 31, 1999, the Company through its indirectly wholly
owned subsidiary, Encore Wire Limited, a Texas limited partnership, completed an
unsecured loan facility with a group of banks (the "Financing Agreement"). The
Financing Agreement replaced the Company's existing credit facility, and the
Company is a guarantor of the indebtedness. The Financing Agreement has been
amended once since August 31, 1999, to extend the term to May 31, 2003. The
Financing Agreement provides for maximum borrowings of the lesser of $65.0
million or the amount of eligible accounts receivable plus the amount of
eligible finished goods and raw materials, less any available reserves
established by the banks. The calculated maximum borrowing amount available at
March 31, 2001, as computed under the Financing Agreement, was $65.0 million.
The Financing Agreement is unsecured and contains customary covenants and events
of default. The Company was in compliance with these covenants, as amended, as
of March 31, 2001. Pursuant to the Financing Agreement, the Company is
prohibited from declaring, paying or issuing cash dividends. At March 31, 2001,
the balance outstanding under the Financing Agreement was $38.0 million. Amounts
outstanding under the Financing Agreement are payable on May 31, 2003 with
interest due quarterly based on the bank's prime rate or LIBOR rate options, at
the Company's election.

NOTE 5 - STOCK REPURCHASE AUTHORIZATION

         On March 24, 1995, the Company announced that its Board of Directors
had authorized it to purchase up to 900,000 shares, or approximately 5.6%, of
its outstanding common stock dependent upon market conditions. Subsequent Board
actions increased this authorization. As of March 31, 2001, the Company had
repurchased an aggregate of 1,615,800 shares of its common stock in the open
market.

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

GENERAL

         The Company is a low-cost manufacturer of copper electrical building
wire and cable. The Company is a significant supplier of residential wire for
interior wiring in homes, apartments and manufactured housing and commercial
wire for commercial and industrial buildings.

         Price competition for electrical wire and cable is intense, and the
Company sells its products in accordance with prevailing market prices. Copper
is the principal raw material used by the Company in manufacturing its products.
Copper accounted for approximately 63.9%, 60.6%, 66.2%, 73.8% and 77.4% of the
Company's cost of goods sold during fiscal 2000, 1999, 1998, 1997 and 1996,
respectively. The price of copper fluctuates, depending on general economic
conditions and in relation to supply and demand and other factors, which has
caused monthly variations in the cost of copper purchased by the Company. The
Company cannot predict copper prices in the future or the effect of fluctuations
in the cost of copper on the Company's future operating results.

         The following discussion and analysis relates to factors that have
affected the operating results of the Company for the three month period ended
March 31, 2001 and 2000. Reference should also be made to the audited financial
statements and notes thereto included in the Company's Annual Report on Form
10-K for the year ended December 31, 2000.

RESULTS OF OPERATIONS

         Net sales for the first quarter of 2001 amounted to $69.8 million
compared with net sales of $67.0 million for the first quarter of 2000. This
dollar increase was due to an increase in the volume of product shipped. Sales
volume increased primarily as a result of market share gains. The average sales
price per copper pound of product sold was down in the first quarter of 2001,
compared to the first quarter of 2000. Fluctuations in sales prices are
primarily a result of changing copper raw material prices and product price
competition.

         The cost of goods sold was $59.9 million in the first quarter of 2001,
compared to $57.9 million in the first quarter of 2000. Copper costs increased
to $41.1 million in the first quarter of 2001 compared to $35.8 million in the
first quarter of 2000. This increase was due to the higher volume of copper in
the first quarter of 2001 compared to the first quarter of 2000. The average
cost per copper pound purchased remained constant at $.85 in the first quarter
of 2000 versus the first quarter of 2000. Copper costs as a percentage of net
sales increased to 58.9% in the first quarter of 2001 from 53.4% in the first
quarter of 2000. This increase as a percentage of net sales in the first quarter
of 2001 from the comparable quarter in 2000 was primarily due to a decreased
differential between what the Company paid per pound of copper purchased and the
Company's net sales price per copper pound sold. This differential decreased in
the first quarter of 2001 due to intense



                                                                              9
<PAGE>   10
                                                                        FORM 10Q


competitive pricing for the Company's products. Other raw material costs as a
percentage of net sales decreased to 13.3% in the first quarter of 2001,
compared with 15.0% in the first quarter of 2000. This decrease as a percentage
of sales was a result of other raw material costs per copper pound decreasing
due to market conditions, volume rebates and cost saving programs.

         Depreciation, labor and overhead costs as a percentage of net sales
remained constant at 16.0% in the first quarter of 2001 versus the first quarter
of 2000. This was due to tight cost controls and the increased volume offsetting
the lower pricing prevalent in the marketplace.

         Inventories are stated at the lower of cost, determined by the last in,
first out (LIFO) method, or market. As permitted by generally accepted
accounting principles, the Company maintains its inventory costs and cost of
goods sold on a first in, first out (FIFO) basis and makes a quarterly LIFO
adjustment to adjust total inventory and cost of goods sold to LIFO. As a result
of decreases in the price of copper during the first quarter of 2001 versus
existing LIFO inventory layers and the reduction of current inventory value, the
value of all inventory at March 31, 2001 using the LIFO method was greater than
its FIFO value by approximately $4.0 million, resulting in a corresponding
decrease in the cost of goods sold of $2.6 million. At March 31, 2001, the LIFO
cost basis of the inventory exceeded the market value by $1,000,000. Thus, at
March 31, 2001 a $1,000,000 addition was made to the LCM reserve. Future
reductions in the price of copper could require the Company to record a lower of
cost or market adjustment against the related inventory balance, which would
result in a negative impact on net income. Additionally, a reduction in the
quantity of inventory in any period could cause copper that is carried in
inventory at costs different from the cost of copper in that period to be
included at the different price in cost of goods sold for that period.

         Gross profit increased to $9.8 million, or 14.1% of net sales, for the
first quarter of 2001 versus $9.2 million, or 13.7% of net sales, for the first
quarter of 2000. The increase in gross profit as a percentage of net sales was
due primarily to increased sales volume and the cost of goods sold factors in
the first quarter of 2001, as discussed above, partially offset by an
increasingly competitive pricing environment for the Company's products.

         Selling expenses for the first quarter of 2001 were $4.3 million, or
6.1% of net sales, compared to $4.3 million, or 6.4% of net sales, in the first
quarter of 2000. The percentage decrease was due to a lower percentage of sales
paid out in commissions due to a change in the mix of product sold. General and
administrative expenses increased to $1.7 million, or 2.4% of net sales, in the
first quarter of 2000 compared to $1.5 million, or 2.2% of net sales, in the
first quarter of 2000. This increase was due primarily to increased costs
relating to the Company's information systems upgrade and infrastructure put in
place for increased sales volume.

        Net interest expense was $660,000 in the first quarter of 2001 compared
to $1,015,000 in the first quarter of 2000. The decrease was due to a lower
average debt balance outstanding during the first quarter of 2001 than the
comparable period during 2000, coupled with lower interest rates. The lower
rates are a result of general interest rate declines and a decline in the
Company's interest rate due to balance sheet ratios reaching trigger points in
the debt agreements.

         As a result of the foregoing factors, the Company's net income
increased to $2.0 million in the first quarter of 2001 from $1.5 million in the
first quarter of 2000.


                                                                              10

LIQUIDITY AND CAPITAL RESOURCES

         The Company maintains a substantial inventory of finished products to
satisfy customers' prompt delivery requirements. As is customary in the
industry, the Company provides payment terms to most of its customers that
exceed terms that it receives from its suppliers. Therefore, the Company's
liquidity needs have generally consisted of operating capital necessary to
finance these receivables and inventory. Capital expenditures have historically
been necessary to expand the production capacity of the Company's manufacturing
operations. The Company has satisfied its liquidity and capital expenditure
needs with cash generated from operations, borrowings under its revolving credit
facilities and sales of its common stock.

         Note 4 of the Notes to Consolidated Financial Statements in Part I is
incorporated herein by reference as if fully restated herein.

         Cash provided by operations was $7.3 million in the first quarter of
2001 compared to $2.5 million in the first quarter of 2000. This increase in
cash provided by operations primarily resulted from a reduction in accounts
receivable in the first quarter of 2001 versus an increase in the first quarter
of 2000. Cash used in investing activities remained constant at $900,000 in the
first quarter of 2001 and 2000. In both quarters, these funds were used
primarily for routine production capacity projects. The $5.2 million of cash
used by financing activities in the first quarter of 2001 was used to repay
borrowings under the Company's line of credit ($4.6 million) and to purchase
treasury stock ($662,000).

         During 2001, the Company expects its capital expenditures will consist
of additional plant and equipment for its residential and commercial wire
operations. The Company will continue to manage its working capital
requirements. These requirements may increase as a result of expected continued
sales increases. These requirements will be impacted by the price of copper. The
Company believes that the cash flow from operations and the financing that it
expects to receive from its banks under the Financing Agreement will satisfy
working capital and capital expenditure requirements for the next twelve months.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

         There have been no material changes from the information provided in
Item 7.A. of the Company's Annual Report on Form 10-K for the year ended
December 31, 2000.

one or more of these risks or uncertainties materialize, or should underlying
assumptions prove incorrect, actual results may vary materially from those
expected. Among the key factors that may have a direct bearing on the Company's
operating results are fluctuations in the economy and in the level of activity
in the building and construction industry, demand for the Company's products,
the impact of price competition and fluctuations in the price of copper.
