WAUKEGAN, Ill., May 9, 2013 — Coleman Cable, Inc. (NASDAQ: CCIX) (the “Company,” “Coleman,” “we,” “us,” or “our”), a leading manufacturer and innovator of electrical and electronic wire and cable products, announced first-quarter 2013 financial results.

Outlook and Dividend

First Quarter 2013 Results

Net sales for the first quarter of 2013 were $222.5 million compared to $220.5 million for the first quarter of 2012. The increase mainly reflects a greater contribution from the Company’s Engineered Solutions segment, which includes results for Watteredge, as partially offset by nominally lower sales volumes and lower average copper prices. First-quarter 2013 Adjusted EPS and Adjusted EBITDA were $0.37 per diluted share and $22.1 million, respectively, compared to $0.24 per diluted share and $19.0 million, respectively, for the first quarter of 2012.

President and CEO Gary Yetman stated, “We have enjoyed a strong start to 2013 with record first quarter Adjusted EBITDA of $22.1 million and Adjusted EPS growth of over 54 percent. Contributing to our results was stronger gross profit performance across all three segments. Our efforts in recent years to diversify our business and enhance our operating platform continue to benefit our business.”

Mr. Yetman concluded, “We anticipate additional benefit in the back half of the year, given a continuation of momentum seen recently in U.S. residential and commercial construction markets. Any protracted copper price volatility, as seen recently, may present some challenges in the near-term, but longer-term, we believe we are well positioned to capture the significant benefit we should get from a sustained rebound in housing and commercial construction.”

On a GAAP basis, the Company recorded earnings of $0.30 per diluted share for the first quarter of 2013 compared to $0.21 per diluted share for the first quarter last year. GAAP results for the 2013 and 2012 periods included restructuring charges and share-based compensation expense. These items are excluded from the Company’s Adjusted EBITDA and Adjusted EPS results. Please see the discussion of Non-GAAP results below and the attached schedules for a full reconciliation of GAAP results to non-GAAP results.

Quarterly Cash Dividend

On May 7, 2013, Coleman’s board of directors declared a quarterly cash dividend of $0.04 per share payable on May 31, 2013, to stockholders of record as of the close of business on May 17, 2013. Future declarations of quarterly dividends are subject to approval of the board of directors and may be adjusted as business needs or market conditions change.

Non-GAAP Results

In addition to net income determined in accordance with GAAP, we use certain non-GAAP measures in assessing our operating performance. These non-GAAP measures used by management include: (1) Adjusted EBITDA, which is net income before net interest, income taxes, depreciation and amortization expense (“EBITDA”) adjusted to exclude the impact of certain specifically identified items (“Adjusted EBITDA”) and (2) Adjusted earnings per share, which we calculate as diluted earnings per share adjusted to exclude the estimated per share impact of the same specifically identified items used to calculate Adjusted EBITDA (“Adjusted EPS”). For the periods presented in this press release, the specifically identified items include restructuring charges and share-based compensation expense.

We believe Adjusted EBITDA serves as an appropriate measure to be used in evaluating the performance of our business. We use Adjusted EBITDA in the preparation of our annual operating budgets and in determining levels of operating and capital investments. We believe Adjusted EBITDA allows us to readily view operating trends, perform analytical comparisons and identify strategies to improve operating performance. The usefulness of Adjusted EBITDA as a performance measure is limited because it excludes the impact of interest expense, depreciation and amortization expense, and taxes. Due to these limitations, we do not, and you should not, use

Adjusted 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 Adjusted EBITDA differently and, as a result, our measure of Adjusted EBITDA may not be directly comparable to Adjusted EBITDA measures of other companies.

Similarly, we believe our use of Adjusted EPS provides an appropriate measure to use in assessing our performance across periods given that this measure provides an adjustment for certain significant items, the magnitude of which may vary significantly from period to period. However, we do not, and do not recommend that you, solely use Adjusted EPS to assess our financial and earnings performance. We also use, and recommend that you use, diluted earnings per share in addition to Adjusted EPS in assessing our earnings performance. Finally, other companies may define Adjusted EPS differently and, as a result, our measure of Adjusted EPS may not be directly comparable to Adjusted EPS measures of other companies
