Exhibit 99.3

Preliminary Unaudited Pro Forma Condensed Combined Financial Statements

On May 16, 2011, Coleman Cable Inc. (“Company,” “Coleman,” “us,” “we,” or “our”) became the owner of 100% of the common stock of Technology Research Corporation and its subsidiaries (“TRC”) for total consideration of approximately $51.5 million. The consideration transferred was calculated based on Coleman’s agreement with TRC to redeem all of TRC’s outstanding shares at an agreed upon price of $7.20 per share. To finance the acquisition, Coleman utilized cash on hand in combination with borrowings under its revolving credit facility. Because the acquisition was not effective until May 16, 2011, the results of TRC were not included in Coleman’s results of operations for the year ended December 31, 2010 or the three months ended March 31, 2011. The following preliminary unaudited pro forma condensed combined financial statements have been prepared to give effect to the completed acquisition, which was accounted for using the purchase method of accounting.

The preliminary unaudited pro forma condensed combined balance sheet presented below gives effect to the acquisition and the Company’s related borrowings under its revolving credit facility (collectively, the “Pro Forma Events”) as if they occurred on March 31, 2011, and combines the historical balance sheets of Coleman and TRC as of March 31, 2011. The preliminary unaudited pro forma condensed combined balance sheet includes adjustments that are both recurring and nonrecurring in nature. The preliminary unaudited pro forma condensed combined statement of income for the year ended December 31, 2010 gives effect to the Pro Forma Events as if they occurred on January 1, 2010, and combines the historical consolidated statement of income for Coleman for the year ended December 31, 2010 with the historical consolidated statement of income for TRC for their fiscal year ended March 31, 2011. Given TRC’s year-end differs from that of Coleman by fewer than 93 days, the historical financial information presented herein for TRC has not been recast to account for the difference in year ends. The preliminary unaudited pro forma condensed combined statement of income for the three months ended March 31, 2011 gives effect to the Pro Forma Events as if they occurred on January 1, 2010, and combines the historical consolidated statements of income for the three months ended March 31, 2011 for both Coleman and TRC. The preliminary unaudited pro forma condensed statements of income do not include adjustments that are nonrecurring in nature.

The preliminary unaudited pro forma condensed combined financial statements presented are based on the assumptions and adjustments described in the accompanying notes. As required, the preliminary unaudited pro forma condensed combined financial information includes adjustments which give effect to events that are directly attributable to the transaction and factually supportable; as such, any planned adjustments affecting the balance sheet, income statement or shares of common stock outstanding subsequent to the assumed acquisition completion date are not included. The statements are presented for illustrative purposes only, and are not necessarily indicative of what the actual combined financial position or results of operations would have been had the Pro Forma Events actually been completed on the dates indicated or what such financial position or results will be for future periods.

The preliminary unaudited pro forma condensed combined financial information was prepared using the purchase method of accounting. Accordingly, we have adjusted the historical consolidated financial information to give effect to the purchase price paid in connection with the acquisition. We have completed the valuation of tangible assets, with the exception of income-tax related assets, and do not expect any significant changes in the valuation of such assets to result from finalizing our purchase accounting. We have valued intangible assets and liabilities based on facts and information obtained thus far as of the date of preparing the purchase price allocation presented herein. The obtaining of additional information or facts may result in a change in the composition or value allocated to one or more intangible assets or liabilities, or in the estimated useful lives assigned to one or more of such assets. Any excess of the fair value of the consideration paid over the fair value of the assets acquired and liabilities assumed is reflected as goodwill in the accompanying preliminary unaudited pro forma condensed combined balance sheet. The preliminary unaudited pro forma condensed combined statement of income does not include the impacts of any revenue, cost or other synergies that may result from the acquisition or any related restructuring costs other than the elimination of sales and costs of sales between the two entities. Cost savings, if achieved, could result from, among other things, material sourcing and elimination of redundant costs, including headcount and facilities.

We will continue to review TRC’s accounting policies to determine if it may be necessary to harmonize any differences between those policies and our policies. The preliminary unaudited pro forma condensed combined financial information does not adjust for any differences in accounting policies between those of Coleman and TRC. Based on our review of TRC’s summary of significant accounting policies disclosed in TRC’s historical financial data, the nature and amount of any adjustments to the historical financial data of TRC to conform their accounting policies to those of Coleman are not expected to be significant.

The preliminary unaudited pro forma condensed combined financial information is derived from and should be read in conjunction with the historical consolidated financial statements and related notes of Coleman and the historical consolidated financial statements and related notes of TRC.

Property, Plant and Equipment, Amortizable Intangible Assets and Goodwill

Property, plant and equipment will be depreciated over the following useful lives: Buildings range from 9 to 20 years; leasehold improvements equal the shorter of the useful life of the asset or the lease term; machinery, fixtures and equipment range from 3 to 8 years.

The preliminary estimated fair value of intangible assets and the respective individual weighted-average useful life at the acquisition date are as follows:

The above intangible assets will be amortized on an accelerated basis based on the estimated pattern of economic benefit derived from the rate the assets will be consumed. Estimated amortization expense for these intangible assets over the next five years is as follows:

Pro Forma Adjustments

Pro forma adjustments give effect to the acquisition under the purchase method of accounting; the use of available excess cash; borrowings under our revolving credit facility; the payment of professional fees and other merger-related expenses; and the recording of assets acquired and certain liabilities assumed.

Notes to Preliminary Unaudited Pro Forma Condensed Combined Financial Statements

Purchase Price

The purchase price was approximately $51.5 million. The purchase price was comprised of a cash payout including the fair value of other consideration transferred, and the fair value of Coleman’s previously held interest in TRC. The fair value of other consideration paid relates to share-based awards paid to TRC employees as a result of change of control provisions in the original award agreements. Additionally, prior to the merger, Coleman owned 323,710 shares of TRC common stock worth $7.20 per share as a result of the agreed upon purchase price. In accordance with relevant accounting guidance, the fair value of the previously owned investment was included in the total purchase price.

Under the purchase method of accounting, the total purchase price as shown in the table above was allocated to net tangible and intangible assets of TRC based on their estimated fair values. The allocations are preliminary and subject to change based upon the finalizations of management’s valuation analysis and income taxes.

The table below summarizes the purchase price allocation of the assets acquired and liabilities assumed as if the acquisition date was March 31, 2011. The preliminary allocation of the purchase price to the fair value of TRC’s assets acquired and liabilities assumed in the Pro Forma Events is as follows:

The preliminary purchase price allocation will be finalized in the future based upon the finalization of the valuation analysis of acquired net assets and income taxes. Accordingly, the preliminary purchase price allocation adjustments have been made solely for the purpose of preparing these statements. The preliminary unaudited pro forma condensed combined statement of income does not include the impact of the reversal into cost of sales of the purchase accounting adjustment for the increase in fair value of inventory.

Pro forma EBITDA:

EBITDA

EBITDA represents net income before interest, income taxes, depreciation, and amortization expense. EBITDA is a non-GAAP financial measure. We are providing this information to permit a more complete comparative analysis of our operating performance relative to other companies. Other companies may define EBITDA differently, and, as a result, our measure of EBITDA may not be directly comparable to EBITDA of other companies.

We believe EBITDA serves as an appropriate measure to be used in evaluating the performance of our business. We employ the use of this measure in the preparation of our annual operating budgets and in determining levels of operating and capital investments. We believe EBITDA allows us to readily view operating trends, perform analytical comparisons and identify strategies to improve operating performance. We also believe EBITDA is a performance measure that provides investors, securities analysts and other interested parties a measure of operating results unaffected by differences in capital structures, business acquisitions, capital investment cycles and ages of related assets among otherwise comparable companies in our industry. However, the usefulness of EBITDA as a performance measure is limited by the fact that it excludes the impact of interest expense, depreciation and amortization expense, and taxes. We borrow money in order to finance our operations; therefore, interest expense is a necessary element of our costs and ability to generate revenue. Similarly, our use of capital assets makes depreciation and amortization expense a necessary element of our costs and ability to generate income. Since we are subject to state and federal income taxes, any measure that excludes tax expense has material limitations. Due to these limitations, we do not, and you should not, use EBITDA as the only measures of our performance. We also use, and recommend that you consider, net income in accordance with GAAP as a measure of our performance. Finally, other companies may define EBITDA differently and, as a result, our measure of EBITDA may not be directly comparable to EBITDA measures of other companies.

Pro Forma Adjustments

The following pro forma adjustments are based on preliminary estimates, which may change as additional information is obtained:
