Exhibit 99.1

TRW Reports First Quarter 2015 Financial Results

LIVONIA, MICHIGAN, May 5, 2015 — TRW Automotive Holdings Corp. (NYSE: TRW), the global leader in active and passive safety systems, today reported first quarter 2015 financial results with sales of $4.1 billion, an increase of 7% compared to the prior year period excluding the effects of currency and divested businesses.  The Company reported GAAP first quarter net earnings of $366 million or $3.13 per diluted share, which compares to net earnings of $199 million or $1.68 per diluted share in the prior year period.

The first quarter 2015 results include a pre-tax gain of $186 million on the previously announced sale of TRW’s Engine Valve business to Federal-Mogul Holdings Corporation (NASDAQ: FDM), which closed during the quarter. Excluding this gain and other special items from the TRW’s current and prior year quarterly results, the Company reported first quarter 2015 net earnings of $235 million, or $2.01 per diluted share, an increase of 11% compared to last year’s first quarter earnings of $1.81 per diluted share.

As previously announced, the Company entered into a definitive agreement with ZF Friedrichshafen AG (“ZF”) on September 15, 2014 under which ZF will acquire all outstanding shares of TRW for $105.60 per share in an all-cash transaction.  The transaction is expected to close by the end of June 2015.

“TRW achieved a strong start to 2015, which will provide a solid foundation as we enter the merger with ZF,” said John C. Plant, Chairman and Chief Executive Officer.  “The agreement signed with ZF, which we expect to close during the second quarter, provides significant benefits for our shareholders who will receive full and certain value for their shares, as well as for our employees, customers and communities all of which will reap the benefits of being part of a larger, more diversified global organization.”

First Quarter 2015

The Company reported first quarter 2015 sales of $4.1 billion, a decrease of $300 million from the prior year period.  Excluding the effects of currency ($379 million) and divested businesses ($191 million), sales increased $270 million or 7% compared to the previous year.  The higher level of sales was driven by increasing demand for TRW’s innovative technologies and higher vehicle production volumes.

The Company’s first quarter 2015 operating income was $534 million, compared with $308 million in the 2014 period.  Excluding the $186 million gain on the sale of TRW’s Engine Valve business, restructuring and asset impairment charges totaling $4 million in 2015 and $20 million in 2014, and transaction costs of $2 million in 2015, operating income for the first quarter was $354 million (margin of 8.5%), which compares to $328 million (margin of 7.4%) in the prior year period.  The margin improvement resulted primarily from the positive profit impact of the higher underlying sales, a positive mix of sales and improved operational performance. These benefits were partially offset by a lower level of pension income in the current quarter compared to last year.

Net interest expense for the first quarter of 2015 totaled $23 million, which compares to $31 million in the 2014 period. The current quarter included a $1 million loss on the retirement of debt.

Tax expense for the first quarter of 2015 was $144 million, which compares to a tax expense of $78 million in the prior year period.  The 2015 period included a net tax expense of $48 million primarily related to the gain on the sale of the Engine Valve business.  The 2014 period included a tax benefit of $4 million related to special items.

The Company reported 2015 first quarter GAAP net earnings of $366 million, or $3.13 per diluted share, which compares to GAAP net earnings of $199 million, or $1.68 per diluted share in the 2014 period.

Excluding special items, the Company reported first quarter 2015 net earnings of $235 million, or $2.01 per diluted share, an increase of 11% compared to last year’s first quarter earnings of $1.81 per diluted share.

Earnings before interest, taxes, depreciation and amortization and special items (“adjusted EBITDA”) were $460 million in the first quarter of 2015, compared to the prior year level of $437 million.  See page A5 for a description of the special items excluded in calculating adjusted EBITDA.

Cash Flow and Capital Structure

First quarter 2015 net cash flow used in operating activities was $192 million, which compares to a use of $183 million in the first quarter of 2014.  Capital expenditures were $95 million in the current quarter compared to $105 million last year.  First quarter free cash flow (cash flow from operating activities less capital expenditures) was an outflow of $287 million which is consistent with the prior year quarter’s outflow of $288 million.

During the first quarter of 2015, TRW received net cash proceeds of $313 million relating to the sale of substantially all of TRW’s Engine Valve business, which closed during the first quarter.

As of April 3, 2015, the Company had $1,594 million of debt and $1,017 million of cash and cash equivalents, resulting in net debt (defined as debt less cash and cash equivalents) of $577 million.

Subsequent Events

On April 21, 2015, TRW announced that it had signed a definitive agreement to divest its Linkage and Suspension business for $400 million in cash, subject to working capital and other adjustments, to THK Co., LTD (TSE:6481). The planned divestiture of the Linkage and Suspension business, which has annual sales of approximately $550 million, is expected to close by the end of TRW’s fiscal third quarter and is subject to customary conditions, including regulatory approvals.

2015 Outlook

TRW’s planning assumptions for industry production volumes in 2015 are approximately 17.4 million units in North America and 20.0 million units in Europe, up 2% and flat, respectively, compared to 2014 levels.  The Company continues to expect expansion in vehicle production volumes in China and rest of world regions.  Based on these production levels, the negative impact of lost sales related to divested businesses, primarily the previously announced sale of TRW’s Engine Valve business, and the Company’s expectations for foreign currency exchange rates, full year 2015 sales are expected to range between $16.2 and $16.5 billion.

Reconciliation to GAAP

In addition to GAAP results included within this press release, the Company has provided certain information which is not calculated according to GAAP (“non-GAAP”), such as net earnings, operating income and margin and diluted earnings per share each excluding special items; sales increases; adjusted EBITDA; and free cash flow.  Management uses these non-GAAP measures to evaluate the operating performance of the Company and its business segments and to forecast future periods.  Management believes that investors will likewise find these non-GAAP measures useful in evaluating such performance.  Such measures are frequently used by security analysts, institutional investors and other interested parties in the evaluation of companies in our industry.

Non-GAAP measures should not be considered in isolation or as a substitute for our reported results prepared in accordance with GAAP and, as calculated, may not be comparable to similarly titled measures of other companies.  For a reconciliation of non-GAAP measures to the most comparable GAAP financial measure and for share amounts used to derive earnings per share, please see the financial schedules that accompany this release.

Reconciliation of Non-GAAP Financial Measures

(Unaudited)

EBITDA, Adjusted EBITDA and free cash flow are not recognized terms under GAAP and do not purport to be alternatives to the most comparable GAAP amounts.  Further, since all companies do not use identical calculations, our definition and presentation of these measures may not be comparable to similarly titled measures reported by other companies.

EBITDA and Adjusted EBITDA

EBITDA as calculated below is a measure used by management to evaluate the operating performance of the Company and its business segments and to forecast future periods.  Adjusted EBITDA is defined as EBITDA excluding restructuring charges, asset impairments, loss on retirement of debt-net and other significant special items.  Management uses Adjusted EBITDA to evaluate the performance of ongoing operations separate from items that may have a disproportionate impact in any particular period.  EBITDA and Adjusted EBITDA are frequently used by securities analysts, institutional investors and other interested parties in the evaluation of companies in our industry.

EBITDA and Adjusted EBITDA do not purport to be alternatives to net earnings as an indicator of operating performance, nor to cash flows from operating activities as a measure of liquidity.  Additionally, neither is intended to be a measure of free cash flow for management’s discretionary use, as they do not consider certain cash requirements such as interest payments, tax payments and debt service requirements.

Free Cash Flow

Free cash flow represents net cash provided by (used in) operating activities less capital expenditures, and is used by management in analyzing the Company’s ability to service and repay its debt and to forecast future periods.  However, this measure does not represent funds available for investment or other discretionary uses since it does not deduct cash used to service debt or for other non-discretionary expenditures.
