Item 7.01 Regulation FD Disclosure

As previously announced, on June 10, 2013, Exide Technologies (the “Company,” or the “Debtor”) filed a voluntary petition (the “Chapter 11 Case”) for relief under Chapter 11 of Title 11 of the United States Code in the United States Bankruptcy Court for the District of Delaware (the “Bankruptcy Court”).

On November 17, 2014, the Debtor filed with the Bankruptcy Court (1) a proposed plan of reorganization (as may be amended, modified or supplemented from time to time, the “Proposed Plan”) and (2) a related proposed disclosure statement (as may be amended, modified or supplemented from time to time, the “Proposed Disclosure Statement”). The Proposed Plan is consistent with that certain plan support agreement (the “PSA”) entered into among the Company and with the holders of a majority of the outstanding principal amount of Exide’s senior secured notes on November 4, 2014, which was attached to the Company’s Form 8-K report filed on November 5, 2014.

Copies of the filed Proposed Plan and related Proposed Disclosure Statement are attached hereto as Exhibit 99.1 and Exhibit 99.2, respectively. Also attached hereto as Exhibit 99.3 is a press release issued by the Company acknowledging the filing of the Proposed Plan and Proposed Disclosure Statement.

Information contained in the Proposed Plan and the Proposed Disclosure Statement is subject to change. The Proposed Plan is subject to acceptance by certain of the Debtor’s creditors and confirmation by the Bankruptcy Court. There can be no assurances that the requisite acceptances to the Proposed Plan can be obtained from the Debtor’s creditors, that the Bankruptcy Court will approve the Proposed Disclosure Statement, or that the Bankruptcy Court will confirm the Proposed Plan.

The Bankruptcy Code does not permit solicitation of acceptances of the Proposed Plan until the Bankruptcy Court approves the Proposed Disclosure Statement as providing adequate information of a kind, and in sufficient detail, as far as is reasonably practicable in light of the nature and history of the Debtor and the condition of the Debtor’s books and records, that would enable a hypothetical investor typical of the holders of claims against the Debtor to make an informed judgment about the Proposed Plan. The Bankruptcy Court has not yet approved the Proposed Disclosure Statement. Accordingly, this Current Report on Form 8-K is not intended to be, nor should it be construed as, a solicitation for a vote on the Proposed Plan.

Under the terms of the Proposed Plan, all shares of the Company’s common stock would be cancelled upon effectiveness of the Proposed Plan, and the Company’s shareholders would not receive or retain any distribution or other property on account of their shares.

The information in Item 7.01 of this report is being furnished, not filed, pursuant to Regulation FD. Accordingly, the information in Item 7.01 of this report will not be incorporated by reference into any registration statement filed by the Registrant under the Securities Act of 1933, as amended, unless specifically identified therein as being incorporated therein by reference. The furnishing of the information in this report is not intended to, and does not, constitute a determination or admission by the Registrant that the information in this report is material or complete, or that investors should consider this information before making an investment decision with respect to any security of the Registrant or any of its affiliates.

Safe Harbor for Forward Looking Statements

This current report on Form 8-K and Exhibits 99.1, 99.2, and Financial Projections hereto contain “forward-looking statements” as defined in the U.S. Private Securities Litigation Reform Act of 1995. All statements that address activities, events or developments that we intend, expect, plan, project, believe or anticipate will or may occur in the future are forward-looking statements. By their nature, forward-looking statements involve risks and uncertainties because they relate to events and depend on circumstances that may or may not occur in the future. The Company undertakes no obligation to update or revise any forward-looking statements.

2

Examples of forward-looking statements include, but are not limited to (a) projections of revenues, cost of raw materials, income or loss, earnings or loss per share, capital expenditures, growth prospects, dividends, the effect of currency translations, capital structure, and other financial items, (b) statements of plans and objectives of the Company or its management or Board of Directors, including the introduction of new products, or estimates or predictions of actions by customers, suppliers, competitors or regulating authorities, (c) statements of future economic performance, (d) statements regarding liquidity and (e) statements of assumptions, such as the prevailing weather conditions in the Company’s market areas, underlying other statements and statements about the Company or its business, and (f) statements regarding tax and liquidity impacts from asset sales and restructuring activities.

Factors that could cause actual results to differ materially from these forward looking statements include, but are not limited to, those identified on Exhibit 99.1 and Exhibit 99.2.
