<Page> Exhibit 99.1 Foster Wheeler Announces Second-Quarter Financial Results HAMILTON, Bermuda--(BUSINESS WIRE)--Aug. 4, 2004--Foster Wheeler Ltd. (OTCBB:FWLRF) today reported net earnings of $29.8 million for the second quarter of 2004, or $0.61 per diluted share. This compares with a net loss for the same quarter of last year of $29.3 million, or $0.72 per diluted share. Revenues for the second quarter of 2004 totaled $669.8 million compared with $935.8 million in the second quarter of last year. Consolidated earnings before income taxes, interest expense, depreciation and amortization (EBITDA) for the second quarter of 2004 were $83.6 million compared with $9.0 million in the second quarter of 2003. The quarter's results included a pre-tax gain of $8.7 million on the sale of development rights related to an Italian power project. The sale of the power project development rights was recorded as a one-time gain, and the company anticipates no further such sales this year. However, the business in Italy has historically developed and sold such project rights, and it is actively continuing to develop other project rights that are expected to be offered for sale in the future. The quarter's results also included a net pre-tax asbestos gain of $1.7 million, and pre-tax charges of $4.7 million for professional service expenses and severance benefits driven by the company's balance sheet and operational restructuring process. Last year's quarter included pre-tax charges of $16.0 million for professional services and severance benefits, pre-tax charges of $6.1 million resulting from pension curtailment and revaluation, and net pre-tax charges of $19.5 million related to five North American projects. "Project execution by our North American Power and European Engineering and Construction Group operations was better than expected and drove our quarterly earnings," said Raymond J. Milchovich, chairman, president and chief executive officer. "During the quarter, we successfully completed several large projects ahead of schedule, earned performance bonuses, passed performance tests, and agreed with a customer to eliminate any warranty obligations on a major project. Although I am extremely pleased with these results, I do not expect to see earnings of this magnitude for the balance of the year. Several large contracts were completed during the second quarter, and, over the remainder of this year, we do not expect our remaining backlog to generate the level of profits reported this quarter." For the six months ended June 25, 2004, revenues were $1.4 billion, down from $1.7 billion in the first six months of last year. The net earnings for the period were $25.5 million compared with a net loss of $49.2 million in the first six months of 2003. Pre-tax charges of $60.8 million were included in the first six months of 2003. Extension for Filing Form 10-Q The company today is extending through August 9, 2004 the time for filing its Form 10-Q for the second quarter of 2004. It is doing so because one of the company's foreign subsidiaries is a party to performance bonding arrangements with financial institutions which contain certain financial covenants. The company requires additional time to evaluate its compliance and course of action with respect to these financial covenants. In connection with this analysis, the company is also evaluating the effectiveness of its disclosure controls and procedures. The company expects its usual earnings conference call to be rescheduled for a date in the near future, which date will be separately announced. <Page> Worldwide Cash and Domestic Liquidity Worldwide, total cash and short-term investments at the end of the quarter were $404.7 million, compared with $430.2 million at year-end 2003, and $419.3 million at the end of the second quarter of 2003. The quarter-end cash and short-term investments included $327.2 million held by non-U.S. subsidiaries. As of June 25, 2004, the company's indebtedness was $1.0 billion, down $16 million from year-end 2003 and $75 million from the end of the second quarter of 2003. "Assuming we successfully complete our equity-for-debt exchange offer and replace our existing revolving credit facility with a new multi-year facility, we forecast that our domestic liquidity, which includes cash and unused credit line availability, will remain sufficient throughout the next 12 months," commented Mr. Milchovich. The company recently announced that significant numbers of institutional investors have agreed to tender their securities in the exchange offer. The company is in the process of distributing offering materials related to the exchange offer as amended. The exchange offer has been extended through August 30, 2004, subject to further extension. Bookings and Segment Performance New orders booked during the second quarter of 2004 were $707.0 million, up approximately 9% from $647.1 million in the second quarter of last year. In the quarter, new orders exceeded revenues for the first time since the third quarter of 2002. The company's backlog at the end of the second quarter of 2004 was $2.3 billion, down from $3.3 billion at the end of the second quarter of 2003, and essentially flat with year-end 2003. Second-quarter new bookings for the Engineering and Construction (E&C) Group were $601.9 million, up from $460.4 million during the year-ago quarter and at the highest level for our current E&C businesses since the fourth quarter of 2001. The Group's quarter-end backlog was $1.6 billion, down $0.6 billion compared with $2.2 billion at the end of the second quarter of 2003, but up from $1.3 billion at year-end 2003. Revenues for the E&C Group in the second quarter of 2004 were $426.1 million, down approximately 19% compared with $529.2 million in the second quarter of 2003. The Group's EBITDA was $55.9 million this quarter, up substantially from $13.9 million for the same period last year. Included in EBITDA for this quarter is a gain of $8.7 million on the sale of the development rights on a power project in Italy. Last year's EBITDA included a gain of $2.5 million on the settlement of a claim and losses of $15.0 million on three separate projects. New bookings in the second quarter for the Energy Group were $105.2 million, compared with $187.4 million in second quarter 2003. Backlog at quarter-end was $692.8 million, down substantially from $1.2 billion at the end of the second quarter of 2003. Energy Group revenues for the quarter were $256.3 million, compared with $409.3 million in the same quarter of 2003. The Group's EBITDA for the quarter was $48.3 million compared with $29.3 million in the same quarter last year. <Page> Non-Cash Amounts Related to Asbestos The company settled with additional asbestos insurance carriers during the second quarter of 2004, reversing an additional $1.7 million of a $68.1 million non-cash charge recorded in the fourth quarter of 2003. This brings, as anticipated, the total amount of the 2003 charge reversed to $13.4 million. The company plans to continue its strategy of settling with insurance carriers by monetizing policies or arranging coverage in place agreements. This strategy is designed to reduce future cash payments from the company to cover asbestos liabilities. The company continues to project that it will not be required to fund any asbestos liabilities from its cash flow before 2010. Calculation of EBITDA Management uses several financial metrics to measure the performance of the company's business segments. EBITDA is a supplemental, non-generally accepted accounting principle (GAAP) financial measure. EBITDA is defined as earnings/(loss) before taxes, interest expense, depreciation and amortization. The company presents EBITDA because it believes it is an important supplemental measure of operating performance. A reconciliation of EBITDA, a non-GAAP financial measure, to net earnings/(loss), a GAAP measure, is shown below. <Page> RECONCILIATION OF EBITDA TO NET EARNINGS/(LOSS) (In Millions of Dollars) Three months ended June 25, 2004 Corporate & E&C Energy Financial Total ------------------------------ EBITDA 55.9 48.3 (20.6) 83.6 Less: Interest Expense(*) 2.8 8.3 14.5 25.6 Less: Depreciation and amortization 2.7 5.1 0.6 8.4 ------------------------------ Earnings/(loss) before income taxes 50.4 34.9 (35.7) 49.6 Less: Provision/(benefit) for income taxes 12.5 17.9 (10.6) 19.8 ------------------------------ ------------------------------ Net earnings/(loss) 37.9 17.0 (25.1) 29.8 ------------------------------ Three months ended June 27, 2003 Corporate & E&C Energy Financial Total ------------------------------ EBITDA 13.9 29.3 (34.2) 9.0 Less: Interest Expense(*) 1.4 7.2 14.3 22.9 Less: Depreciation and amortization 2.2 5.2 1.1 8.5 ------------------------------ Earnings/(loss) before income taxes 10.3 16.9 (49.6) (22.4) Less: Provision/(benefit) for income taxes 2.2 6.1 (1.4) 6.9 ------------------------------ ------------------------------ Net earnings/(loss) 8.1 10.8 (48.2) (29.3) ------------------------------ (*) Includes interest expense on subordinated deferrable interest debentures in 2004 and mandatorily redeemable preferred security distributions of subsidiary trust in 2003. <Page> The company believes that the line item on its consolidated statement of operations entitled "net earnings/(loss)" is the most directly comparable GAAP measure to EBITDA. Since EBITDA is not a measure of performance calculated in accordance with GAAP, it should not be considered in isolation of, or as a substitute for, net earnings/(loss) as an indicator of operating performance. EBITDA, as the company calculates it, may not be comparable to similarly titled measures employed by other companies. In addition, this measure does not necessarily represent funds available for discretionary use, and is not necessarily a measure of the company's ability to fund its cash needs. As EBITDA excludes certain financial information compared with net earnings/(loss), the most directly comparable GAAP financial measure, users of this financial information should consider the type of events and transactions which are excluded. EBITDA, adjusted for certain unusual and infrequent items specifically excluded in the terms of the Senior Credit Facility, is also used as a measure for certain covenants under the Senior Credit Facility. The company's non-GAAP performance measure, EBITDA, has certain material limitations as follows: -- It does not include interest expense. Because the company has borrowed substantial amounts of money to finance some of its operations, interest is a necessary and ongoing part of its costs and has assisted it in generating revenue. Therefore, any measure that excludes interest expense has material limitations; -- It does not include taxes. Because the payment of taxes is a necessary and ongoing part of the company's operations, any measure that excludes taxes has material limitations; -- It does not include depreciation. Because the company must utilize substantial property, plant and equipment in order to generate revenues in its operations, depreciation is a necessary and ongoing part of its costs. Therefore any measure that excludes depreciation has material limitations. Notes to Editor: 1. Consolidated Statements follow. 2.
