Exhibit 99.1

ITEM 1. BUSINESS

GENERAL

     The term “Cooper” refers to the registrant, Cooper Industries plc, which was incorporated under the laws of Ireland on June 4, 2009, and became the successor-registrant to Cooper Industries, Ltd. on September 9, 2009. Cooper Industries, Ltd. was incorporated under the laws of Bermuda on May 22, 2001, and became the successor registrant to Cooper Industries, Inc. on May 22, 2002.

     In June 2009, our Board of Directors approved moving Cooper’s place of incorporation from Bermuda to Ireland. This move was part of a reorganization that created a newly formed Irish company, Cooper Industries plc. We completed the first step in this reorganization by establishing our tax residency in Ireland in December 2008. At a Special Shareholders’ Meeting on August 31, 2009, shareholders voted in favor of completing the reorganization pursuant to which all Cooper Industries, Ltd. Class A common shares held by public shareholders would be cancelled and all holders of such shares would receive ordinary shares of Cooper Industries plc on a one-for-one basis. The reorganization transaction was completed on September 8, 2009, following approval from the Supreme Court of Bermuda, at which time Cooper Industries plc replaced Cooper Industries, Ltd. as the ultimate parent company. On October 19, 2009, the Irish High Court approved the reduction of share premium (similar to additional paid-in-capital) to establish distributable reserves in the statutory balance sheet of Cooper Industries plc. The establishment of distributable reserves was required to enable the Company to pay dividends and repurchase shares in the future.

     We believe being an Irish company offers increased strategic flexibility and operational benefits as we continue to expand the growing international portion of our business. We do not expect the reorganization to have any material impact on our financial results. Shares of the Irish company, Cooper Industries plc, began trading on the New York Stock Exchange on September 9, 2009 under the symbol “CBE”, the same symbol under which Cooper Industries, Ltd. shares were previously traded. Cooper Industries plc remains subject to the U.S. Securities and Exchange Commission reporting requirements, the mandates of the Sarbanes-Oxley Act and applicable corporate governance rules of the New York Stock Exchange.

     On March 26, 2010, Cooper announced entering into a Framework Agreement with Danaher Corporation to create a joint venture combining our Tools business with certain Tools businesses from Danaher’s Tools and Components Segment (the “Joint Venture”). On July 6, 2010, Cooper announced the completion of the Joint Venture, named Apex Tools Group, LLC. Cooper and Danaher each own a 50% interest in the Joint Venture, have equal representation on its Board of Directors and have a 50% voting interest in the Joint Venture. At completion of the transaction in July 2010, Cooper deconsolidated the Tools business assets and liabilities contributed to the Joint Venture and recognized Cooper’s 50% ownership interest as an equity investment.

     During the first quarter of 2010, Cooper revised its segment reporting to align its external reporting with changes to its internal reporting structure and in conjunction with the announcement of the Tools joint venture. The former Electrical Products segment has been divided into two new reportable segments. Following this change, Cooper’s operations consist of three segments: Energy and Safety Solutions, Electrical Products Group and Tools. Beginning in the third quarter of 2010 following completion of the Tools joint venture, Cooper will have two reportable segments. Cooper manufactures markets and sells its products and provides services throughout the world. Cooper has manufacturing facilities in 23 countries and currently employs approximately 28,200 people. Operations in the United States are conducted by wholly-owned subsidiaries of Cooper, organized by the three business segments. Activities outside the United States contribute significantly to the revenues and operating earnings of all three segments of Cooper. These activities are conducted in major industrialized countries by wholly-owned subsidiaries and jointly-owned companies, the management of which is structured through Cooper’s business segments. As a result of operations outside the United States, sales and distribution networks are maintained throughout

most of the industrialized world. Cooper generally believes that there are no substantial differences in the business risks associated with operations outside the United States compared with United States activities, although Cooper is subject to certain political and economic uncertainties encountered in activities outside the United States, including trade barriers and restrictions on the exchange and fluctuations of currency. Cooper generates the most non-U.S. revenues in the United Kingdom, Germany, Canada, Mexico, France and the Asia Pacific region. Cooper has operations in India and China and has several majority-owned joint ventures with operations in China. Investments in emerging markets such as India and China are subject to greater risks related to economic and political uncertainties as compared to most countries where Cooper has operations. Exhibit 21.0 contains a list of Cooper’s significant subsidiaries.

     Financial information with respect to Cooper’s industry segments and geographic areas is contained in Note 15 of the Notes to the Consolidated Financial Statements. A discussion of acquisitions and divestitures is included in Notes 3 and 16 of the Notes to the Consolidated Financial Statements.

     With its three business segments, Cooper serves four major markets: the industrial, commercial, utility and residential markets. Cooper also serves the electronics and telecommunications markets. Markets for Cooper’s products and services are worldwide, though the United States is the largest market. Within the United States, there is no material geographic concentration by state or region. Cooper experiences substantial competition in each of its business segments. The number and size of competitors vary considerably depending on the product line. Cooper cannot specify with exactitude the number of competitors in each product category or their relative market position. However, most operating units experience significant competition from both larger and smaller companies with the key competitive factors being customer and end-user service, price, quality, brand name and availability. Cooper considers its reputation as a manufacturer of a broad line of quality products and premier brands to be an important factor in its businesses. Cooper believes that it is among the leading manufacturers in the world of electrical distribution equipment, support systems, hazardous duty electrical equipment, lighting fixtures, emergency lighting, fuses, nonpower hand tools and industrial power tools.

     Cooper’s research and development activities are for purposes of improving existing products and services and originating new products. During 2009, approximately $141.1 million was spent for research and development activities as compared with approximately $141.8 million in 2008 and $105.7 million in 2007. Cooper obtains and holds patents on products and designs in the United States and many other countries where operations are conducted or products are sold. Although in the aggregate Cooper’s patents are important in the operation of its businesses, the loss by expiration or otherwise of any one patent or license or group of patents or licenses would not materially affect its business.

     Cooper does not presently anticipate that compliance with currently applicable environmental regulations and controls will significantly change its competitive position, capital spending or earnings during 2010. Cooper has been a party to administrative and legal proceedings with governmental agencies that have arisen under statutory provisions regulating the discharge or potential discharge of material into the environment. Orders and decrees consented to by Cooper, or currently under negotiation with state regulatory agencies, have contained agreed-upon timetables for fulfilling reporting or remediation obligations or maintaining specified air and water discharge levels in connection with permits for the operations of various plants. Cooper believes it is in compliance with the orders and decrees, and such compliance is not material to the business or financial condition of Cooper. For additional information concerning Cooper’s accruals for environmental liabilities, see Note 7 of the Notes to the Consolidated Financial Statements.

     Approximately 60 percent of the United States hourly production work force of Cooper is employed in 43 manufacturing facilities, distribution centers and warehouses not covered by labor agreements. Numerous agreements covering approximately 40 percent of all hourly production employees exist with 15 bargaining units at 17 operations in the United States. We also have agreements with various unions at 20 operations in other countries. During 2009, new agreements were concluded covering hourly

2

production employees at 8 operations in the United States. Cooper considers its employee relations to be excellent.

     Sales backlog at December 31, 2009 was approximately $573.9 million, all of which is for delivery during 2010, compared with backlog of approximately $678.9 million at December 31, 2008.

     The following describes the business conducted by each of Cooper’s business segments. Additional information regarding the products, markets and distribution methods for each segment is set forth in the table at the end of this Item. Information concerning market conditions, as well as information concerning revenues and operating earnings for each segment, is included under “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations.”

Energy and Safety Solutions

     The Energy & Safety Solutions segment includes the Cooper Crouse-Hinds, Cooper Power Systems, and Cooper Safety Divisions. This segment manufactures, markets and sells electrical protection products, including fittings, plugs, receptacles, cable glands, hazardous duty electrical equipment, intrinsically safe explosion-proof instrumentation, emergency lighting, fire detection and mass notification systems and security products for use in residential, commercial and industrial construction and maintenance and repair applications. The segment also manufactures, markets and sells products for use by utilities and in industry for electrical power transmission and distribution, including distribution switchgear, transformers, transformer terminations and accessories, capacitors, voltage regulators, surge arresters, energy automation solutions and other related power systems components.

Tools

     The Tools segment manufactures markets and sells hand tools for industrial, construction, electronics and consumer markets; automated assembly systems for industrial markets; and electric and pneumatic industrial power tools, related electronics and software control and monitoring systems for general industry, primarily automotive and aerospace manufacturers.

     The principal raw material requirements include: flat and bar stock steel, brass, copper, fiberglass, aluminum, metal castings and forgings, wood, plastic pellets and plastic sheet. These materials are available from and supplied by numerous sources located in the United States and other countries.

     Demand for nonpowered hand tools, assembly systems and industrial power tools are driven by employment levels and industrial activity in major industrial countries and by consumer spending. In addition, demand for industrial power tools is influenced by automotive and aerospace production and general industrial production. The segment’s products are sold by the company’s sales force, independent distributors and retailers.

     As discussed above, in July 2010, Cooper contributed substantially all of the assets and liabilities of the Tools segment to the Apex Tools Group joint venture. At completion of the transaction in July 2010, Cooper deconsolidated the Tools business assets and liabilities contributed to the Joint Venture and recognized Cooper’s 50% ownership interest as an equity investment.
