NEWS RELEASE EXHIBIT 99.1 [LOGO] 1000 Six PPG Place Pittsburgh, PA 15222-5479 contact: Bill Acton (PR) 412/394-2872 Dan Greenfield (IR) 412/394-3004 Gary Stechmesser (IR) 412/394-2861 ALLEGHENY TELEDYNE PROPOSES TO ACQUIRE LUKENS INC. FOR $28 IN CASH PER COMMON SHARE; PROPOSAL VALUE IS $715 MILLION, INCLUDING ASSUMED DEBT; PROPOSED ACQUISITION IS STRATEGIC, PRO-COMPETITIVE AND ACCRETIVE TO EARNINGS AND CASH FLOW Pittsburgh, PA, December 22, 1997 - Allegheny Teledyne Incorporated (NYSE:ALT) today announced that it has proposed to acquire Lukens Inc. (NYSE:LUC) in a merger transaction in which holders of Lukens common shares would receive $28 per share in cash. The proposal is valued at $715 million, including assumed debt. In a letter delivered to the Lukens board of directors, Richard P. Simmons, chairman, president and chief executive officer of Allegheny Teledyne, stated that Allegheny Teledyne is prepared to enter into a merger agreement substantially identical to the agreement Lukens announced with Bethlehem Steel Corporation (NYSE:BS) last week. Simmons noted that Allegheny Teledyne's proposal of $28 per share in cash represents a 12 percent premium to the stated value of the Bethlehem Steel proposal to acquire Lukens at $25 per share. The Allegheny Teledyne proposal is fully financed, and would be subject only to customary conditions, including receipt of Lukens shareholder approval and all necessary regulatory approvals, including antitrust clearance. Page 5 of 8 Pages Simmons commented, "We are convinced that our proposed acquisition of Lukens is founded on firm strategic planning, is pro-competitive, and creates the opportunity for significant synergies and cost savings. The combination is expected to be accretive to our earnings and cash flow, after taking account of synergies, in its first full year. We expect the acquisition to produce continuing operational and financial synergies worth about $50 million in the first full year and nearly $70 million in the second full year. These amounts include the utilization of Allegheny Teledyne's pension surplus to cover the unfunded pension liabilities of Lukens as well as the annual cost of its retiree medical obligations. The merger will be accounted for as a purchase, which is expected to create continuing non-cash charges of approximately $10 million per year. We are confident that, with Lukens' cooperation, we can complete our transaction quickly. We trust the Lukens board will recognize its fiduciary duties and accept our clearly superior offer to enter into a merger agreement." A copy of Allegheny Teledyne's letter to the Lukens board of directors is attached. Allegheny Teledyne Incorporated is a group of technology-based manufacturing companies with significant concentration in specialty metals, complemented by aerospace and electronics, industrial, and consumer products. In October 1997, Allegheny Teledyne agreed to acquire Oregon Metallurgical Corporation (Nasdaq:OREM).

SIMMONS [LOGO] Chairman of the Board, 1000 Six PPG Place President and Chief Executive Officer Pittsburgh, PA 15222-5479 Phone: 412.394.2808 Facsimile: 412.394.3005 December 22, 1997 To the Members of the Board of Directors of Lukens Inc.: We were surprised and disappointed to learn of your agreement to sell Lukens Inc. to Bethlehem Steel Corporation. We have worked for over a year with your management and advisors, at your invitation, to structure a transaction which would combine our businesses and reward your stockholders. We believed we had reached an agreement with your company and were disappointed that we were not given an opportunity, despite our obvious interest, to continue to participate in the process. We continue to believe in a combination of Allegheny Teledyne Incorporated and Lukens and its benefits for each of our shareholders and for your employees. The Allegheny Teledyne Board of Directors has authorized our offer to acquire Lukens for $28 in cash for each outstanding common share of Lukens. We are enclosing a merger agreement which we are prepared to enter into immediately after you have terminated the Bethlehem agreement in accordance with its terms because of our superior offer. This agreement is substantially identical to the one entered into by Lukens and Bethlehem, with changes appropriate to reflect an all-cash transaction. In evaluating our proposal, you should consider that: The proposal is an all-cash offer; The proposal is fully financed; We propose to dispose of the same assets as Bethlehem; The financial and other terms of our proposal are clearly superior to the proposed Bethlehem transaction. Your decision to sell to Bethlehem has created an obligation on your part to secure the best price for your stockholders. Our cash offer is clearly superior to Bethlehem's cash and stock offer. Bethlehem's compounded total return to shareholders over the last three years was negative 58 percent, and it currently receives a sub-investment grade corporate credit rating of single-B-plus from Standard & Poor's rating agency. We are confident that we can complete our transaction quickly. Your management and advisors already have complete information regarding our financial and operating Page 7 of 8 Pages Lukens Inc. December 22, 1997 Page 2 capabilities. Additionally, we have reviewed with them our ability to obtain all regulatory approvals necessary to complete a transaction, including HSR clearances, and, in the course of meetings with your representatives, they indicated that they concurred with our analysis. Because of the significance of this transaction to our stockholders and to the marketplace and reflecting our commitment to complete this combination, we are making this letter publicly available. The importance of this matter to our companies is great. We are prepared to meet with you and your advisors to finalize a merger agreement immediately. We look forward to your prompt response to our offer. Sincerely, Richard P. Simmons Page 8 of 8 Pages
