News Release

Belden Reports Strong Results for First Quarter 2018

St. Louis, Missouri - May 2, 2018 - Belden Inc. (NYSE: BDC), a global leader in high quality, end-to-end signal transmission solutions for mission-critical applications, today reported fiscal first quarter 2018 results for the period ended April 1, 2018.

First Quarter 2018

On a GAAP basis, revenues for the quarter totaled $605.6 million, increasing $54.2 million, or 9.8%, compared to $551.4 million in the first quarter 2017. Net income was $2.6 million, a decrease of $23.1 million from the prior-year period. Net income was impacted by a $15.2 million after-tax loss on debt extinguishment related to our recent debt refinancing and repayment. In addition, net income for the first quarter 2018 included after-tax restructuring and acquisition integration costs of $16.0 million, primarily related to the acquisition of Snell Advanced Media (“SAM”), which was completed during the quarter. Net income as a percentage of revenues was 0.4% compared to 4.7% in the prior-year period. EPS was $(0.15) compared to $0.40 in the first quarter 2017.

Adjusted revenues for the quarter totaled $607.4 million, increasing $56.0 million, or 10.2%, compared to $551.4 million in the first quarter 2017. Adjusted EBITDA margin in the first quarter was 17.0%, increasing 10 basis points from 16.9% in the year-ago period. Adjusted EPS was $1.16 compared to $0.92 in the first quarter 2017. Adjusted results are non-GAAP measures, and a non-GAAP reconciliation table is provided as an appendix to this release.

John Stroup, President, CEO, and Chairman of Belden Inc., said, “I am pleased to start the year with 10% revenue growth and robust adjusted earnings growth. During the first quarter, we continued to execute our balanced capital deployment strategy, which included an attractive acquisition and debt refinancing at very favorable terms. In addition, we allocated a quarterly record $75 million towards our share repurchase program.”

Outlook

“We are increasing our full-year revenue guidance to reflect the SAM acquisition. We are also updating our EPS guidance to reflect the impact of this acquisition, our recent debt refinancing, and our share repurchases.” said Mr. Stroup.

On a GAAP basis, the Company expects second quarter 2018 revenues to be $647 - $667 million and EPS to be $0.37 - $0.47. For the full year ending December 31, 2018, the Company now expects revenues to be $2.623 - $2.673 billion, compared to prior guidance of $2.528 - $2.578 billion and EPS to be $2.44 - $2.69, compared to prior guidance of $3.96 - $4.21. The decline in EPS is primarily attributable to acquisition integration costs and losses on debt extinguishment.

The Company expects second quarter 2018 adjusted revenues to be $650 - $670 million and adjusted EPS to be $1.41 - $1.51. For the full year ending December 31, 2018, the Company increased adjusted revenue and EPS guidance to reflect the recent acquisition, debt refinancing, and share repurchases. The Company now expects adjusted revenues to be $2.633 - $2.683 billion, compared to prior guidance of $2.528 - $2.578 billion and adjusted EPS to be $6.23 - $6.48, compared to prior guidance of $5.95 - $6.20.

Segment Combination

In the first quarter, the Company changed its organizational structure and, as a result, now will be reporting two segments. The segments formerly known as Enterprise Solutions and Broadcast Solutions now will be presented as the Enterprise Solutions segment, and the segments formerly known as Industrial Solutions and Network Solutions now will be presented as the Industrial Solutions segment. The reorganization allows the Company to further accelerate progress in key strategic areas, and the segment

consolidation properly aligns our external reporting with the way the businesses are now managed. Prior period segment information has been revised to conform to the change in the composition of reportable segments and is included as an appendix to this release.

Earnings Conference Call

Management will host a conference call today at 8:30 am ET to discuss results of the quarter. The listen-only audio of the conference call will be broadcast live via the Internet at http://investor.belden.com. The dial-in number for participants in the U.S. is 800-281-7973; the dial-in number for participants outside the U.S. is 323-794-2093. A replay of this conference call will remain accessible in the investor relations section of the Company’s website for a limited time.

RECONCILIATION OF NON-GAAP MEASURES

(Unaudited)

In addition to reporting financial results in accordance with accounting principles generally accepted in the United States, we provide non-GAAP operating results adjusted for certain items, including: asset impairments; accelerated depreciation expense due to plant consolidation activities; purchase accounting effects related to acquisitions, such as the adjustment of acquired inventory and deferred revenue to fair value and transaction costs; severance, restructuring, and acquisition integration costs; gains (losses) recognized on the disposal of businesses and tangible assets; amortization of intangible assets; gains (losses) on debt extinguishment; certain revenues and gains (losses) from patent settlements; discontinued operations; and other costs. We adjust for the items listed above in all periods presented, unless the impact is clearly immaterial to our financial statements. When we calculate the tax effect of the adjustments, we include all current and deferred income tax expense commensurate with the adjusted measure of pre-tax profitability.

We utilize the adjusted results to review our ongoing operations without the effect of these adjustments and for comparison to budgeted operating results. We believe the adjusted results are useful to investors because they help them compare our results to previous periods and provide important insights into underlying trends in the business and how management oversees our business operations on a day-to-day basis. As an example, we adjust for the purchase accounting effect of recording deferred revenue at fair value in order to reflect the revenues that would have otherwise been recorded by acquired businesses had they remained as independent entities. We believe this presentation is useful in evaluating the underlying performance of acquired companies. Similarly, we adjust for other acquisition-related expenses, such as amortization of intangibles and other impacts of fair value adjustments because they generally are not related to the acquired business' core business performance. As an additional example, we exclude the costs of restructuring programs, which can occur from time to time for our current businesses and/or recently acquired businesses. We exclude the costs in calculating adjusted results to allow us and investors to evaluate the performance of the business based upon its expected ongoing operating structure. We believe the adjusted measures, accompanied by the disclosure of the costs of these programs, provides valuable insight.

Adjusted results should be considered only in conjunction with results reported according to accounting principles generally accepted in the United States.

RECONCILIATION OF NON-GAAP MEASURES

(Unaudited)

We define free cash flow, which is a non-GAAP financial measure, as net cash from operating activities adjusted for capital expenditures net of the proceeds from the disposal of tangible assets. We believe free cash flow provides useful information to investors regarding our ability to generate cash from business operations that is available for acquisitions and other investments, service of debt principal, dividends and share repurchases. We use free cash flow, as defined, as one financial measure to monitor and evaluate performance and liquidity. Non-GAAP financial measures should be considered only in conjunction with financial measures reported according to accounting principles generally accepted in the United States. Our definition of free cash flow may differ from definitions used by other companies.
