Exhibit 99.1

Allegheny Technologies Announces Strong First Quarter 2005 Results

PITTSBURGH--(BUSINESS WIRE)--April 21, 2005--Allegheny Technologies Incorporated (NYSE:ATI)

Allegheny Technologies Incorporated (NYSE:ATI) reported net income for the first quarter 2005 of $66.3 million, or $0.66 per share, on sales of $879.6 million.

In the first quarter 2004, ATI reported a net loss of $50.4 million, or $(0.63) per share, on sales of $577.8 million.

"Our strong first quarter results are a good start to achieving the next level of success for ATI," said L. Patrick Hassey, Chairman, President and Chief Executive Officer of Allegheny Technologies.

"Robust demand from the early stage recovery of the commercial aerospace market drove High Performance Metals segment results. We continue to be encouraged by the improved market and cost position of our Flat-Rolled Products segment. Our Engineered Products segment also performed very well and is becoming more important to our results.

"ATI sales increased by 52% compared to the first quarter 2004 and by more than 13% compared to the fourth quarter 2004. Overall segment operating profit improved to $114 million, and operating margins reached nearly 13% of sales.

"Operating performance benefited from strong demand, higher selling prices, ongoing cost reductions and capital investments, and from ATI Business System manufacturing initiatives.

"First quarter operating margin in our High Performance Metals segment exceeded 24%. Demand was robust from the aerospace market for our titanium alloys, nickel-based superalloys, and vacuum melted specialty steels. In addition, our exotic alloys business had another outstanding quarter due to continued government, corrosion, and medical market strength.

"First quarter results in our Flat-Rolled Products segment were good. We expect to do better. Shipments were 172,800 tons and segment operating margin was 7.5%. Operating and quality costs were higher than expected as we balanced production flow in the first quarter. In addition, some of our stainless steel sheet service center and tubing customers were adjusting their inventories, which had risen at the end of 2004, due in part to an import surge in December. Stainless steel sheet imports through February 2005, the latest data available, returned to approximately the 2004 monthly average. Importantly, most end markets for our flat-rolled products remained solid.

"In our Engineered Products segment, operating margins increased to over 12% as a result of ATI Business System improvements and strong demand from several key markets, such as oil and gas, aerospace, and transportation markets as well as general manufacturing.

"We remain optimistic about the prospects for ATI. Backlogs in our High Performance Metals segment are at near record levels and lead times continue to lengthen. We expect sustained demand for our materials used for jet engine after-market parts and new commercial jet engines and airframes. In addition, we see continued strength for our exotic alloys. In our Flat-Rolled Products segment, capital goods markets are expected to remain strong. We believe stainless steel service center supply chain inventories will be in balance by the end of the second quarter 2005. The global electrical steel markets for power distribution are looking for added supply as that market gains momentum. Markets for our Engineered Products segment businesses remain robust."

Retirement Benefit Expense

Income Taxes

The 2005 first quarter includes a provision for income taxes of $2.3 million, which is principally related to foreign and state income taxes. No income tax provision or benefit was recognized in 2004. We maintain a valuation allowance 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 net operating tax loss carry-forwards resulting in cash tax payments, or when tax losses, if any, are recoverable as cash refunds, or due to changes in our judgment regarding the realizability of our deferred tax assets.

Cash Flow, Working Capital and Debt

New Accounting Pronouncement Adopted in 2005

In the first quarter 2005, the Company adopted Statement of Financial Accounting Standards No. 123R, "Share-Based Payment". Under the revised standard, companies may no longer account for share-based compensation transactions, such as stock options, restricted stock, and potential payments under programs such as our Total Shareholder Return plans, using the intrinsic value method as defined in APB Opinion No. 25. Instead, companies are required to account for such equity transactions using an approach in which the fair value of an award is estimated at the date of grant and recognized as an expense over the requisite service period. Compensation expense is adjusted for equity awards that do not vest because service or performance conditions are not satisfied. However, compensation expense already recognized is not adjusted if market conditions are not met, such as stock options expiring "out-of-the-money". We adopted the new standard using the modified prospective method and beginning with the first quarter 2005 will reflect compensation expense in accordance with the SFAS 123R transition provisions. Under the modified prospective method, the effect of the standard is recognized in the period of adoption and in future periods. Prior periods are not restated to reflect the impact of adopting the new standard at earlier dates.

First quarter 2005 compensation expense related to share-based incentive plans was $2.7 million compared to $1.2 million in the first quarter 2004. First quarter 2005 share-based compensation expense includes $0.8 million related to expensing of stock options.

Allegheny Technologies will conduct a conference call with investors and analysts on April 21, 2005, at 1 p.m. ET to discuss the financial results. The conference call will be broadcast live on www.alleghenytechnologies.com. To access the broadcast, click on "Conference Call".

As part of managing the liquidity in our business, we focus on controlling managed working capital, which is defined as gross accounts receivable and gross inventories, less accounts payable. In measuring performance in controlling this managed working capital, we exclude the effects of LIFO inventory valuation reserves, excess and obsolete inventory reserves, and reserves for uncollectible accounts receivable which, due to their nature, are managed separately.

In managing the overall capital structure of the Company, one of the measures on which we focus is net debt to total capitalization, which is the percentage of debt to the total invested and borrowed capital of the Company. In determining this measure, debt and total capitalization are net of cash on hand which may be available to reduce borrowings.
