             Allegheny Technologies Announces First Quarter Results

    --  Sales increased 20% compared to the first quarter 2003

    --  First quarter loss of $50.4 million, or $0.63 per share,
        includes a LIFO inventory valuation reserve increase of $48.1
        million related to significantly higher raw materials costs

    --  Cost reductions, before the effects of inflation, totaled
        $26.6 million in the first quarter 2004

    PITTSBURGH, PA - April 21, 2004 - Allegheny Technologies Incorporated
(NYSE:ATI) reported a net loss of $50.4 million, or $0.63 per share,
on sales of $577.8 million for the first quarter ended March 31, 2004.
Results included a LIFO (last-in, first-out) inventory valuation
reserve increase of $48.1 million, primarily due to the effects of
rapidly rising raw materials costs, which increased approximately 30%
in the first quarter 2004 compared to the fourth quarter 2003.
Retirement benefit expense, primarily non-cash, was $36.0 million, or
$0.45 per share, in the quarter. First quarter 2004 results do not
include an income tax benefit as a result of a deferred tax valuation
allowance recorded in the fourth quarter 2003.
    In the first quarter 2003, ATI reported a net loss before the
cumulative effect of a change in accounting principle of $25.8
million, or $0.32 per share, on sales of $480.5 million. First quarter
2003 results included a LIFO inventory valuation reserve increase of
$3.0 million and retirement benefit expense, primarily non-cash, of
$34.8 million, or $0.28 per share. First quarter 2003 results included
an income tax benefit of $14.2 million, or $0.18 per share.
    "We saw the first signs of real strength in market demand for many
of our products during the first quarter 2004. Strong demand is
continuing in the second quarter, and we are currently booking orders
into the third quarter," said Pat Hassey, ATI's President and Chief
Executive Officer. "Compared to the first quarter 2003, Flat-Rolled
Products segment sales increased 28%, High Performance Metals segment
sales increased 11% and Engineered Products segment sales increased
12%.
    "In our Flat-Rolled Products segment, demand from a variety of
markets improved, particularly for our high-value products such as
strip, Precision Rolled Strip(R), nickel alloys, specialty steel and
titanium products. During the first quarter, flat-rolled products
base-selling prices began to recover from historical lows. The
stainless steel commodity cold-rolled sheet base-selling price, which
excludes the impact of raw material surcharges, increased by over 10%
from the historical low price in December 2003. Price increases along
with surcharge revisions have been effective in helping to offset
rapidly rising raw materials costs on a cash basis.
    "In our High Performance Metals segment, demand for our
nickel-based superalloys and premium titanium alloys improved. We saw
more stable inventory in the supply chain, improving demand for spare
parts from the commercial aerospace market, and continued strong
demand from the military aerospace market. Our exotic alloys business
continued to perform well. Demand remained strong from the government
market, super-conducting applications for the high energy physics
market and corrosion markets, such as chemical processing,
particularly in Asia.
    "Our newly expanded state-of-the-art long products rolling mill
began production in April on budget and on schedule. This advanced
rolling mill, located in Richburg, South Carolina, provides enhanced
technological capabilities enabling ATI to grow our high performance
metals business.
    "Sales in our Engineered Products segment increased as a result of
improved demand from several key markets, as well as a pickup in
overall manufacturing demand.
    "The ATI Business System is driving lean manufacturing, quality
improvement and cost reductions throughout the Company. For example,
even though raw materials costs rose rapidly during the first quarter,
managed working capital as a percent of annualized sales decreased to
approximately 26% at the end of the quarter compared to nearly 31% at
the end of 2003. We also achieved nearly $27 million of cost
reductions, before the effects of inflation, in the first quarter
2004. We are on track to achieve our $104 million cost reduction goal
for 2004.
    "We are continuing discussions with the United Steelworkers of
America looking for ways to "fix" our stainless steel business and
better secure a strong future for Allegheny Ludlum and its employees.
    "We continue to make progress toward completing the previously
announced acquisition of substantially all of the assets of J&L
Specialty Steel, which remains subject to certain closing conditions.
This acquisition is expected to complement and enhance our competitive
position in the North American flat-rolled stainless steel market. It
maintains historical domestic capacity and keeps significant J&L
equipment in production.
    "As the second quarter 2004 begins, we see improving market
conditions across most of our businesses. In addition, we are
beginning to see less volatility for some of the key raw materials
that we use. If these trends continue, we expect to see gradual
improvement in earnings per share through the remainder of 2004."

    FIRST QUARTER 2004 FINANCIAL HIGHLIGHTS

    --  SALES were $577.8 million, up 20% compared to the first
        quarter 2003. Sales were up 28% in the Flat-Rolled Products
        segment, 11% in the High Performance Metals segment, and 12%
        in the Engineered Products segment. During the quarter, we
        increased base-selling prices for most of our products and
        implemented additional surcharges for certain raw materials
        for many of our products.

    --  LOSS BEFORE TAXES was $50.4 million, compared to last year's
        pretax loss of $40.0 million. Results for 2004 included a LIFO
        inventory valuation reserve increase of $48.1 million, due to
        an approximately 30% increase in costs in the first quarter
        2004 compared to the fourth quarter 2003 for the major raw
        materials that we use. For the same 2003 period, the increase
        to the LIFO inventory valuation reserve was $3.0 million.

    --  RETIREMENT BENEFIT EXPENSE in the first quarter 2004 was $36.0
        million compared to $34.8 million in the first quarter 2003.
        Approximately 82% of the 2004 retirement benefit expense is
        non-cash.

    --  CASH FLOW from operations was a negative $0.2 million in the
        first quarter 2004 due primarily to a $63.1 million increase
        in accounts receivable during the quarter, as well as higher
        gross inventory levels, which were partially offset by
        increased accounts payable. The higher accounts receivable
        resulted from increased sales, including the effects of raw
        material surcharges. Capital expenditures were $12.1 million.
        Cash on-hand ended the quarter at $67.3 million, $12.3 million
        lower than year-end 2003. We had no borrowings outstanding
        under our secured credit facility during the first quarter
        2004.

    --  COST REDUCTIONS, before the effects of inflation, totaled
        $26.6 million company-wide. Our 2004 cost reduction goal is
        $104 million.

    FLAT-ROLLED PRODUCTS SEGMENT

    Market Conditions

    --  Demand improved from capital goods markets while demand from
        automotive and other consumer durables markets remained good.
        Raw material surcharges, which continued to escalate during
        the quarter due to rising raw material prices, combined with
        higher base selling prices, resulted in higher average
        transaction prices compared to the first quarter 2003.

    First quarter 2004 compared to first quarter 2003

    --  Sales increased 28% to $329.6 million primarily due to
        improved demand from capital goods markets, and the impact of
        higher raw material surcharges and base-selling price
        increases. Total tons shipped increased 5%. Shipments of
        commodity products increased 4% and shipments of high-value
        products increased 7%. Average transaction prices, which
        include surcharges, were 22% higher. Average base-selling
        prices, which exclude surcharges, increased by approximately
        3%.

    --  The segment had an operating loss of $11.0 million compared to
        an operating loss of $1.3 million last year. Higher raw
        material costs, which resulted in a LIFO inventory valuation
        reserve increase of $37.6 million in the first quarter 2004,
        offset the benefits of additional surcharges, higher
        base-selling prices and cost reduction initiatives. The 2003
        first quarter included a LIFO inventory valuation reserve
        increase of $3.9 million.

    --  Energy costs increased $2.4 million, net of $0.4 million in
        gains from natural gas derivatives.

    --  Results benefited from $13 million in cost reductions, before
        the effects of inflation.

    HIGH PERFORMANCE METALS SEGMENT

    Market Conditions

    --  Demand for nickel-based superalloys and titanium alloys
        improved as the commercial aerospace supply chain was stable.
        Demand improved for spare parts from the commercial aerospace
        market and remained strong from the military aerospace market.
        Our exotic alloys business continued to benefit from sustained
        high demand from government and high energy physics markets
        and corrosion markets, particularly in Asia.

    First quarter 2004 compared to first quarter 2003

    --  Sales increased 11% to $178.7 million. Shipments were up 3%
        for nickel-based and specialty steel alloys, 9% for titanium
        alloys and 27% for exotic alloys.

    --  Operating profit declined to $7.9 million compared to an
        operating profit of $8.3 million as the impact of higher raw
        material costs offset increased sales and the benefits of cost
        reduction initiatives. The rise in raw material costs resulted
        in a LIFO inventory valuation reserve increase of $8.6 million
        in 2004, compared to $1.0 million in 2003.

    --  Results benefited from $10 million of cost reductions, before
        the effects of inflation.

    ENGINEERED PRODUCTS SEGMENT

    Market Conditions

    --  Demand for tungsten products remained strong from the oil and
        gas market and demand improved for tungsten carbide products
        and cutting tools due to a pickup in overall manufacturing
        activity. Demand improved considerably for forged products
        from the Class 8 truck market and for cast products from the
        improving manufacturing sector and transportation and wind
        energy markets.

    First quarter 2004 compared to first quarter 2003

    --  Sales improved 12% to $69.5 million.

    --  Operating profit improved to $3.8 million compared to $1.8
        million last year due to higher sales volumes, improved
        pricing, and the benefits from cost reductions, which offset
        higher raw material costs. The rise in raw material costs
        resulted in an increase to the LIFO inventory valuation
        reserve of $1.9 million in 2004 compared to a decrease of $1.9
        million in 2003.

    --  Results benefited from $2 million of cost reductions, before
        the effects of inflation.

    RETIREMENT BENEFIT EXPENSE

    --  Retirement benefit expense was $36.0 million in the first
        quarter 2004, compared to $34.8 million in the first quarter
        2003. Approximately $29.7 million of the first quarter 2004
        retirement benefit expense was non-cash.

    --  The 2004 retirement benefit expense does not include the
        expected favorable impact on our postretirement medical
        expense from the enactment of the Federal Medicare
        prescription drug benefit program in December 2003, pending
        final authoritative accounting guidance regarding how the
        benefit is to be recognized in the financial statements.

    --  For the first quarter 2004, retirement benefit expense
        increased cost of sales by $27.6 million, and selling and
        administrative expenses by $8.4 million. For the first quarter
        2003, retirement benefit expense increased cost of sales by
        $24.4 million, and selling and administrative expenses by
        $10.4 million.

    --  ATI is not required to make cash contributions to its defined
        benefit pension plan for 2004 and, based upon current
        actuarial studies, does not expect to be required to make cash
        contributions to its defined benefit pension plan during the
        next several years.

    OTHER EXPENSES

    --  Corporate expenses for the first quarter 2004 were $5.6
        million compared to $4.8 million in the year-ago period. This
        increase is due primarily to non-cash expenses associated with
        the Company's stock-based long-term incentive compensation
        program, which offset savings associated with reductions in
        staffing and other efforts to control costs at the corporate
        office.

    --  Excluding the effects of retirement benefit expense and
        non-cash stock-based compensation expense, selling and
        administrative expenses as a percentage of sales declined to
        7.3% in the 2004 first quarter from 8.6% in the same period of
        2003.

    --  No income tax benefit was recognized in the 2004 first quarter
        since we cannot tax benefit current operating losses due to
        cumulative losses incurred during 2001 through 2003. We
        recorded a valuation allowance in the 2003 fourth quarter for
        a major portion of our deferred tax assets in accordance with
        SFAS No. 109 "Accounting for Income Taxes". Future tax
        provisions or benefits will be recognized when taxable income
        exceeds the 2003 tax loss, or when tax losses, if any, are
        recoverable as cash refunds.

    CASH FLOW, WORKING CAPITAL AND DEBT

    --  Cash on hand was $67.3 million at March 31, 2004, a decrease
        of $12.3 million from 2003 year-end.

    --  First quarter 2004 cash flow from operations was a negative
        $0.2 million due primarily to a $75.4 million increase in
        managed working capital in the quarter, partially offset by
        the receipt of a $6.9 million federal income tax refund
        pertaining to our 2003 tax return.

    --  The increase in managed working capital was due to a $63.1
        million increase in accounts receivable, which reflects the
        higher level of sales in the first quarter 2004, compared to
        the fourth quarter 2003, and a $59.1 million increase in
        inventory mostly as a result of higher raw material costs,
        which was partially offset by a $46.8 million increase in
        accounts payable. The majority of the increase in raw material
        costs should be recovered through surcharges.

    --  At March 31, 2004, managed working capital was 26.4% of
        annualized sales compared to 30.7% of annualized sales at 2003
        year-end. We define managed working capital as accounts
        receivable and gross inventories less accounts payable.

    --  Cash used in investing activities was $10.9 million in the
        first quarter 2004 and consisted primarily of $12.1 million of
        capital expenditures, net of $1.2 million of proceeds from the
        disposal of miscellaneous assets.

    --  Cash used in financing activities was $1.2 million in the
        first quarter 2004, and included a net decrease in debt of
        $3.1 million, primarily due to a $9.5 million repayment of an
        industrial revenue bond partially offset by a $6.5 million net
        increase in borrowings at our STAL China joint venture, and by
        $1.9 million of proceeds received from the exercise of stock
        options.

    --  There were no borrowings outstanding during the first quarter
        2004 under ATI's $325 million secured borrowing facility,
        although a portion of the letters of credit capacity was
        utilized.

    NEW ACCOUNTING PRONOUNCEMENT ADOPTED IN 2003

    The adoption of Statement of Financial Accounting Standards No.
143 "Accounting for Asset Retirement Obligations" ("SFAS 143")
resulted in an after-tax charge of $1.3 million, or $0.02 per share in
the 2003 first quarter. This charge is reported as a cumulative effect
of change in accounting principle.
