Basis of Presentation

The accompanying Condensed Consolidated Financial Statements include Belden Inc. and all of its subsidiaries (the Company, us, we, or our). We eliminate all significant affiliate accounts and transactions in consolidation.

The accompanying Condensed Consolidated Financial Statements presented as of any date other than December 31, 2014:

These Condensed Consolidated Financial Statements should be read in conjunction with the Consolidated Financial Statements and Supplementary Data contained in our 2014 Annual Report on Form 10-K.

Business Description

We are an innovative signal transmission solutions provider built around five global business platforms – Broadcast Solutions, Enterprise Connectivity Solutions, Industrial Connectivity Solutions, Industrial IT Solutions, and Network Security Solutions. Our comprehensive portfolio of signal transmission solutions provides industry leading secure and reliable transmission of data, sound and video for mission critical applications.

Reporting Periods

Our fiscal year and fiscal fourth quarter both end on December 31. Our fiscal first quarter ends on the Sunday falling closest to 91 days after December 31, which was March 29, 2015, the 88th day of our fiscal year 2015. Our fiscal second and third quarters each have 91 days. The three months ended March 30, 2014 included 89 days.

Reclassifications

We have made certain reclassifications to the 2014 Condensed Consolidated Financial Statements with no impact to reported net income in order to conform to the 2015 presentation.

Fair Value Measurement

Accounting guidance for fair value measurements specifies a hierarchy of valuation techniques based upon whether the inputs to those valuation techniques reflect assumptions other market participants would use based upon market data obtained from independent sources or reflect our own assumptions of market participant valuation. The hierarchy is broken down into three levels based on the reliability of the inputs as follows:

-5-

As of and during the three months ended March 29, 2015 and March 30, 2014, we utilized Level 1 inputs to determine the fair value of cash equivalents. We did not have any transfers between Level 1 and Level 2 fair value measurements during the three months ended March 29, 2015.

Cash and Cash Equivalents

We classify cash on hand and deposits in banks, including commercial paper, money market accounts, and other investments with an original maturity of three months or less, that we hold from time to time, as cash and cash equivalents. We periodically have cash equivalents consisting of short-term money market funds and other investments. The primary objective of our investment activities is to preserve our capital for the purpose of funding operations. We do not enter into investments for trading or speculative purposes. The fair value of these cash equivalents as of March 29, 2015 was $0.5 million and is based on quoted market prices in active markets (i.e., Level 1 valuation).

Contingent Liabilities

We have established liabilities for environmental and legal contingencies that are probable of occurrence and reasonably estimable, the amounts of which are currently not material. We accrue environmental remediation costs based on estimates of known environmental remediation exposures developed in consultation with our environmental consultants and legal counsel. We are, from time to time, subject to routine litigation incidental to our business. These lawsuits primarily involve claims for damages arising out of the use of our products, allegations of patent or trademark infringement, and litigation and administrative proceedings involving employment matters and commercial disputes. Based on facts currently available, we believe the disposition of the claims that are pending or asserted will not have a materially adverse effect on our financial position, results of operations, or cash flow.

As of March 29, 2015, we were party to standby letters of credit, surety bonds, and bank guaranties totaling $7.5 million, $1.8 million, and $1.6 million, respectively.

Revenue Recognition

We recognize revenue when all of the following circumstances are satisfied: (1) persuasive evidence of an arrangement exists, (2) price is fixed or determinable, (3) collectability is reasonably assured, and (4) delivery has occurred. Delivery occurs in the period in which the customer takes title and assumes the risks and rewards of ownership of the products specified in the customer’s purchase order or sales agreement. At times, we enter into arrangements that involve the delivery of multiple elements. For these arrangements, when the elements can be separated, the revenue is allocated to each deliverable based on that element’s relative selling price and recognized based on the period of delivery for each element. Generally, we determine relative selling price using our best estimate of selling price, unless we have established vendor specific objective evidence (VSOE) or third party evidence of fair value exists for such arrangements.

We record revenue net of estimated rebates, price allowances, invoicing adjustments, and product returns. We record revisions to these estimates in the period in which the facts that give rise to each revision become known.

-6-

We have certain products subject to the accounting guidance on software revenue recognition. For such products, software license revenue is recognized when persuasive evidence of an arrangement exists, delivery of the product has occurred, the fee is fixed or determinable, collection is probable and VSOE of the fair value of undelivered elements exists. As substantially all of the software licenses are sold in multiple-element arrangements that include either support and maintenance or both support and maintenance and professional services, we use the residual method to determine the amount of software license revenue to be recognized. Under the residual method, consideration is allocated to undelivered elements based upon VSOE of the fair value of those elements, with the residual of the arrangement fee allocated to and recognized as software license revenue. In our Network Security Solutions segment, we have established VSOE of the fair value of support and maintenance, subscription-based software licenses and professional services. Software license revenue is generally recognized upon delivery of the software if all revenue recognition criteria are met.

Revenue allocated to support services under our Network Security Solutions support and maintenance contracts, subscription-based software, and remote ongoing operational services is paid in advance and recognized ratably over the term of the service. Revenue allocated to professional services, including remote implementation services, is recognized as the services are performed.

Discontinued Operations

In 2012, we sold our Thermax and Raydex cable business for $265.6 million in cash and recognized a pre-tax gain of $211.6 million ($124.7 million net of tax). At the time the transaction closed, we received $265.6 million in cash, subject to a working capital adjustment. In the three months ended March 30, 2014, we recognized a $0.9 million ($0.6 million net of tax) loss from disposal of discontinued operations related to this business as a result of settling the working capital adjustment and other matters.

Subsequent Events

We have evaluated subsequent events after the balance sheet date through the financial statement issuance date for appropriate accounting and disclosure.

Pending Adoption of Recent Accounting Pronouncements

In May 2014, the FASB issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers (the ASU), which will replace most existing revenue recognition guidance in U.S. GAAP. The core principle of the ASU is that an entity should recognize revenue for the transfer of goods or services equal to the amount that it expects to be entitled to receive for those goods or services. The ASU requires additional disclosure about the nature, amount, timing and uncertainty of revenue and cash flows arising from customer contracts, including significant judgments and changes in judgments. The ASU will be effective for us beginning January 1, 2017, and allows for both retrospective and modified retrospective methods of adoption. We are in the process of determining the method of adoption and assessing the impact of this ASU on our Consolidated Financial Statements. On April 1, 2015, the FASB proposed a one-year deferral of the effective date of the ASU. Under the proposal, the ASU would be effective for us beginning on January 1, 2018.

In August 2014, the FASB issued disclosure guidance that requires us to evaluate, at each annual and interim period, whether substantial doubt exists about our ability to continue as a going concern, and if applicable, to provide related disclosures. The new guidance will be effective for us for the year ending December 31, 2016. This guidance is not currently expected to have a material effect on our financial statement disclosures upon adoption, although the ultimate impact will be dependent on our financial condition and expected operating outlook at such time.

Tripwire

We acquired 100% of the outstanding ownership interest in Tripwire, Inc. (Tripwire) on January 2, 2015 for a purchase price of $703.2 million. The purchase price was funded with cash on hand and $200.0 million of borrowings under our revolving credit agreement (see Note 8). Tripwire is a leading global provider of advanced threat, security and compliance solutions. Tripwire’s solutions enable enterprises, service providers, manufacturers, and government agencies to detect, prevent, and respond to growing security threats. Tripwire is headquartered in Portland, Oregon. The results of Tripwire have been included in our Consolidated Financial Statements from January 2, 2015. We have determined that Tripwire is a reportable segment, Network Security Solutions. The following table summarizes the preliminary estimated fair value of the assets acquired and the liabilities assumed as of January 2, 2015 (in thousands).

The above purchase price allocation is preliminary, and is subject to revision as additional information about the fair value of individual assets and liabilities becomes available. We are in the process of ensuring our accounting policies are applied at Tripwire. The preliminary measurement of receivables; inventories; property, plant and equipment; intangible assets; goodwill; deferred revenue; deferred income taxes; and other assets and liabilities are subject to change. A change in the estimated fair value of the net assets acquired will change the amount of the purchase price allocable to goodwill.

The fair value of acquired receivables is $37.8 million, with a gross contractual amount of $38.0 million. We do not expect to collect $0.2 million of the acquired receivables.

A single estimate of fair value results from a complex series of judgments about future events and uncertainties and relies heavily on estimates and assumptions. The judgments we have used in estimating the fair values assigned to each class of acquired assets and assumed liabilities could materially affect the results of our operations.

-8-

For purposes of the above allocation, we based our estimate of the fair value for the acquired intangible assets, property, plant and equipment, and deferred revenue on a valuation study performed by a third party valuation firm. We used various valuation methods including discounted cash flows to estimate the fair value of the identifiable intangible assets and deferred revenue (Level 3 valuation). To determine the value of the acquired property, plant, and equipment, we used various valuation methods, including both the market approach, which considers sales prices of similar assets in similar conditions (Level 2 valuation), and the cost approach, which considers the cost to replace the asset adjusted for depreciation (Level 3 valuation).

Goodwill and other intangible assets reflected above were determined to meet the criterion for recognition apart from tangible assets acquired and liabilities assumed. The goodwill is primarily attributable to expected synergies and the assembled workforce. The expected synergies for the Tripwire acquisition primarily consist of an expanded product portfolio with network security solutions that can be marketed to our existing broadcast, enterprise, and industrial customers. We do not have tax basis in the goodwill, and therefore, the goodwill is not deductible for tax purposes. The intangible assets related to the acquisition consisted of the following:

The amortizable intangible assets reflected in the table above were determined by us to have finite lives. The useful life for the developed technology intangible asset was based on the estimated time that the technology provides us with a competitive advantage and thus approximates the period of consumption of the intangible asset. The useful life for the customer relationship intangible asset was based on our forecasts of customer turnover. The useful life of the backlog intangible asset was based on our estimate of when the ordered items would ship.

Trademarks have been determined by us to have indefinite lives and are not being amortized, based on our expectation that the trademarked products will generate cash flows for us for an indefinite period. We expect to maintain use of trademarks on existing products and introduce new products in the future that will also display the trademarks, thus extending their lives indefinitely. In-process research and development assets are considered indefinite-lived intangible assets until the completion or abandonment of the associated research and development efforts. Upon completion of the development process, we will make a determination of the useful life of the asset and begin amortizing the assets over that period. If the project is abandoned, we will write-off the asset at such time.

-9-

Our consolidated revenues and consolidated loss from continuing operations before taxes for the three months ended March 29, 2015 included $18.8 million and $28.6 million, respectively, from Tripwire. Consolidated revenues in the three months ended March 29, 2015 are negatively impacted by approximately $18.4 million due to the reduction of the acquired deferred revenue balance to fair value. Included in our consolidated loss from continuing operations before taxes for the three months ended March 29, 2015 are $11.4 million of amortization of intangible assets and $9.2 million of compensation expense related to the accelerated vesting of acquiree stock based compensation awards.

The following table illustrates the unaudited pro forma effect on operating results as if the Tripwire acquisition had been completed as of January 1, 2014.

For purposes of the pro forma disclosures, the three months ended March 30, 2014 includes nonrecurring expenses from the effects of purchase accounting, including the compensation expense from the accelerated vesting of acquiree stock compensation awards of $9.2 million and amortization of the sales backlog intangible asset of $1.4 million.

The above unaudited pro forma financial information is presented for informational purposes only and does not purport to represent what our results of operations would have been had we completed the acquisition on the date assumed, nor is it necessarily indicative of the results that may be expected in future periods. Pro forma adjustments exclude cost savings from any synergies resulting from the acquisition.

Coast Wire and Plastic Tech

We acquired 100% of the outstanding ownership interest in Coast Wire and Plastic Tech., LLC (Coast) on November 20, 2014 for cash of $36.0 million. Coast is a developer and manufacturer of customized wire and cable solutions used in high-end medical device, military and defense, and industrial applications. Coast is located in Carson, California. The results of Coast have been included in our Consolidated Financial Statements from November 20, 2014, and are reported within the Industrial Connectivity segment. The Coast acquisition was not material to our financial position or results of operations.

ProSoft Technology, Inc.

We acquired 100% of the outstanding shares of ProSoft Technology, Inc. (ProSoft) on June 11, 2014 for cash of $104.1 million. ProSoft is a leading manufacturer of industrial networking products that translate between disparate automation systems, including the various protocols used by different automation vendors. The results of ProSoft have been included in our Consolidated Financial Statements from June 11, 2014, and are reported within the Industrial IT segment. ProSoft is headquartered in Bakersfield, California. The following table summarizes the estimated fair value of the assets acquired and the liabilities assumed as of June 11, 2014 (in thousands).

-10-

The above purchase price allocation is preliminary and is subject to revision as additional information about the fair value of individual assets and liabilities becomes available. We are in the process of ensuring our accounting policies are applied at ProSoft. The preliminary measurement of receivables; inventories; property, plant and equipment; goodwill; deferred income taxes; and other assets and liabilities are subject to change. A change in the estimated fair value of the net assets acquired will change the amount of the purchase price allocable to goodwill. There were no significant changes to the preliminary purchase price allocation as of March 29, 2015 as compared to the preliminary purchase price allocation as of December 31, 2014.

The fair value of acquired receivables is $5.9 million, with a gross contractual amount of $6.2 million. We do not expect to collect $0.3 million of the acquired receivables.

A single estimate of fair value results from a complex series of judgments about future events and uncertainties and relies heavily on estimates and assumptions. The judgments we have used in estimating the fair values assigned to each class of acquired assets and assumed liabilities could materially affect the results of our operations.

For purposes of the above allocation, we based our estimate of the fair value of the acquired inventory and intangible assets on a valuation study performed by a third party valuation firm. We have estimated a fair value adjustment for inventories based on the estimated selling price of the work-in-process and finished goods acquired at the closing date less the sum of the costs to complete the work-in-process, the costs of disposal, and a reasonable profit allowance for our post acquisition selling efforts. We used various valuation methods including discounted cash flows to estimate the fair value of the identifiable intangible assets (Level 3 valuation).

Goodwill and other intangible assets reflected above were determined to meet the criterion for recognition apart from tangible assets acquired and liabilities assumed. The goodwill is primarily attributable to expected synergies and the assembled workforce. The expected synergies for the ProSoft acquisition primarily consist of expanded access to the Industrial IT market and channel partners. Our tax basis in the acquired goodwill is $56.4 million. The goodwill balance we recorded is deductible for tax purposes over a period of 15 years up to the amount of the tax basis. The intangible assets related to the acquisition consisted of the following:

-11-

The amortizable intangible assets reflected in the table above were determined by us to have finite lives. The useful life for the developed technologies intangible asset was based on the estimated time that the technology provides us with a competitive advantage and thus approximates the period of consumption of the intangible asset. The useful life for the customer relationship intangible asset was based on our forecasts of customer turnover. The useful life for the trademarks was based on the period of time we expect to continue to go to market using the trademarks. The useful life of the backlog intangible asset was based on our estimate of when the ordered items would ship.

Our consolidated revenues and consolidated income from continuing operations before taxes for the three months ended March 29, 2015 included $12.3 million and $2.7 million, respectively, from ProSoft. Included in our consolidated income from continuing operations before taxes for the three months ended March 29, 2015 are $1.0 million of amortization of intangible assets.

Grass Valley

We acquired 100% of the outstanding ownership interest in Grass Valley USA, LLC and GVBB Holdings S.a.r.l., (collectively, Grass Valley) on March 31, 2014 for cash of $218.2 million. Grass Valley is a leading provider of innovative technologies for the broadcast industry, including production switchers, cameras, servers, and editing solutions. Grass Valley is headquartered in Hillsboro, Oregon, with significant locations throughout the United States, Europe, and Asia. The results of Grass Valley have been included in our Consolidated Financial Statements from March 31, 2014, and are reported within the Broadcast segment. The following table summarizes the estimated fair value of the assets acquired and the liabilities assumed as of March 31, 2014 (in thousands).

-12-

A single estimate of fair value results from a complex series of judgments about future events and uncertainties and relies heavily on estimates and assumptions. The judgments we have used in estimating the fair values assigned to each class of acquired assets and assumed liabilities could materially affect the results of our operations. There were no significant changes to the purchase price allocation as of March 29, 2015 as compared to the preliminary purchase price allocation as of December 31, 2014.

The fair value of acquired receivables is $67.4 million, with a gross contractual amount of $77.2 million. We do not expect to collect $9.8 million of the acquired receivables.

For purposes of the above allocation, we based our estimate of the fair value of the acquired inventory, property, plant, and equipment, intangible assets, and deferred revenue on a valuation study performed by a third party valuation firm. We have estimated a fair value adjustment for inventories based on the estimated selling price of the work-in-process and finished goods acquired at the closing date less the sum of the costs to complete the work-in-process, the costs of disposal, and a reasonable profit allowance for our post acquisition selling efforts. To determine the value of the acquired property, plant, and equipment, we used various valuation methods, including both the market approach, which considers sales prices of similar assets in similar conditions (Level 2 valuation), and the cost approach, which considers the cost to replace the asset adjusted for depreciation (Level 3 valuation). We used various valuation methods including discounted cash flows to estimate the fair value of the identifiable intangible assets and deferred revenue (Level 3 valuation).

Goodwill and other intangible assets reflected above were determined to meet the criterion for recognition apart from tangible assets acquired and liabilities assumed. The goodwill is primarily attributable to expected synergies and the assembled workforce. The expected synergies for the Grass Valley acquisition primarily consist of cost savings from the ability to consolidate existing and acquired operating facilities and other support functions, as well as expanded access to the Broadcast market. Our estimated tax basis in the acquired goodwill is not significant. The intangible assets related to the acquisition consisted of the following:

-13-

The amortizable intangible assets reflected in the table above were determined by us to have finite lives. The useful life for the developed technologies intangible asset was based on the estimated time that the technology provides us with a competitive advantage and thus approximates the period of consumption of the intangible asset. The useful life for the customer relationship intangible asset was based on our forecasts of customer turnover. The useful life of the backlog intangible asset was based on our estimate of when the ordered items would ship.

Trademarks have been determined by us to have indefinite lives and are not being amortized, based on our expectation that the trademarked products will generate cash flows for us for an indefinite period. We expect to maintain use of trademarks on existing products and introduce new products in the future that will also display the trademarks, thus extending their lives indefinitely. In-process research and development assets are considered indefinite-lived intangible assets until the completion or abandonment of the associated research and development efforts. Upon completion of the development process, we will make a determination of the useful life of the asset and begin amortizing the assets over that period. If the project is abandoned, we will write-off the asset at such time.

Our revenues and loss from continuing operations before taxes for the three months ended March 29, 2015 included $51.0 million and $(8.7) million, respectively, from Grass Valley. Included in our loss from continuing operations before taxes for the three months ended March 29, 2015 are $2.6 million of amortization of intangible assets. We also recognized certain severance, restructuring, and acquisition integration costs in the three months ended March 29, 2015 related to Grass Valley. See Note 7.

The following table illustrates the unaudited pro forma effect on operating results as if the Grass Valley and ProSoft acquisitions had been completed as of January 1, 2013.

-14-

The above unaudited pro forma financial information is presented for informational purposes only and does not purport to represent what our results of operations would have been had we completed the acquisitions on the date assumed, nor is it necessarily indicative of the results that may be expected in future periods. Pro forma adjustments exclude cost savings from any synergies resulting from the acquisition.

We are organized around five global business platforms: Broadcast, Enterprise Connectivity, Industrial Connectivity, Industrial IT, and Network Security. The Network Security platform was formed with our acquisition of Tripwire in January 2015. Each of the global business platforms represents a reportable segment.

Effective January 1, 2015, the key measures of segment profit or loss reviewed by our chief operating decision maker are Segment Revenues and Segment EBITDA. Segment Revenues represent non-affiliate revenues and include revenues that would have otherwise been recorded by acquired businesses as independent entities but were not recognized in our Consolidated Statements of Operations due to the effects of purchase accounting and the associated write-down of acquired deferred revenue to fair value. Segment EBITDA excludes certain items, including depreciation expense; amortization of intangibles; asset impairment; severance, restructuring, and acquisition integration costs; purchase accounting effects related to acquisitions, such as the adjustment of acquired inventory and deferred revenue to fair value; and other costs. We allocate corporate expenses to the segments for purposes of measuring Segment EBITDA. Corporate expenses are allocated on the basis of each segment’s relative EBITDA prior to the allocation. The prior period presentation has been updated accordingly.

Our measure of segment assets does not include cash, goodwill, intangible assets, deferred tax assets, or corporate assets. All goodwill is allocated to reporting units of our segments for purposes of impairment testing.

The following table is a reconciliation of the total of the reportable segments’ Revenues and EBITDA to consolidated revenues and consolidated income (loss) from continuing operations before taxes, respectively.

-15-

(1) For the three months ended March 29, 2015, both our consolidated revenues and gross profit were negatively impacted by approximately $18.4 million, primarily due to the reduction of the acquired deferred revenue balance to fair value associated with our acquisition of Tripwire. In addition, for the three months ended March 29, 2015, our consolidated revenues and gross profit were negatively impacted by approximately $4.1 million and $3.3 million, respectively, primarily due to the reduction of the acquired deferred revenue balance to fair value associated with our acquisition of Grass Valley. See Note 2, Acquisitions.

(2) See Note 7, Severance, Restructuring, and Acquisition Integration Activities, for details by segment .

(3) For the three months ended March 29, 2015, we recognized $9.2 million of compensation expense related to the accelerated vesting of acquiree stock based compensation awards associated with our acquisition of Tripwire. In addition, we recognized $0.3 million of cost of sales related to the adjustment of acquired inventory to fair value related to our acquisition of Coast. See Note 2, Acquisitions .

The following table presents the basis for the income per share computations:

-16-

For the three months ended March 29, 2015 and March 30, 2014, diluted weighted average shares outstanding do not include outstanding equity awards of 0.9 million and 0.1 million, respectively, because to do so would have been anti-dilutive.

For purposes of calculating basic earnings per share, unvested restricted stock units are not included in the calculation of basic weighted average shares outstanding until all necessary conditions have been satisfied and issuance of the shares underlying the restricted stock units is no longer contingent. Necessary conditions are not satisfied until the vesting date, at which time holders of our restricted stock units receive shares of our common stock.

For purposes of calculating diluted earnings per share, unvested restricted stock units are included to the extent that they are dilutive. In determining whether unvested restricted stock units are dilutive, each issuance of restricted stock units is considered separately.

Once a restricted stock unit has vested, it is included in the calculation of both basic and diluted weighted average shares outstanding.

The major classes of inventories were as follows:

Depreciation and Amortization Expense

We recognized depreciation expense in income from continuing operations of $11.5 million and $9.5 million in the three months ended March 29, 2015 and March 30, 2014, respectively. The increase in depreciation expense is primarily due to our acquisitions of Tripwire and Grass Valley.

We recognized amortization expense in income from continuing operations related to our intangible assets of $26.5 million and $11.7 million in the three months ended March 29, 2015 and March 30, 2014, respectively. The increase in amortization expense is primarily due to our acquisitions of Tripwire, Grass Valley, ProSoft, and Coast.

In 2014, we began a productivity improvement program and the integration of our acquisition of Grass Valley. The productivity improvement program is focused on improving the productivity of our sales, marketing, finance, and human resources functions relative to our peers. The majority of the costs for the productivity improvement program relate to the Industrial Connectivity, Enterprise, and Industrial IT segments. The restructuring and integration activities related to our acquisition of Grass Valley are focused on achieving desired cost savings by consolidating existing and acquired operating facilities and other support functions. The Grass Valley costs relate to our Broadcast segment.

-17-

In the three months ended March 29, 2015 and March 30, 2014, we recorded severance, restructuring, and integration costs of $14.5 million and $2.3 million related to these two significant programs, as well other cost reduction actions and the integration of our acquisitions of ProSoft, Coast, and Tripwire. The following table summarizes the costs by segment:

Of the total severance, restructuring, and acquisition integration costs recognized in the three months ended March 29, 2015, $1.4 million, $11.8 million, and $1.3 million were included in cost of sales; selling, general and administrative expenses; and research and development, respectively. Of the total severance, restructuring, and acquisition integration costs recognized in the three months ended March 30, 2014, $1.9 million and $0.4 million were included in selling, general and administrative expenses and research and development, respectively.

The other restructuring and integration costs primarily consisted of costs of integrating manufacturing operations, such as relocating inventory on a global basis, retention bonuses, relocation, travel, reserves for inventory obsolescence as a result of product line integration, costs to consolidate operating and support facilities, and other costs. The majority of the other restructuring and integration costs related to these actions were paid as incurred or are payable within the next 60 days.

The table below sets forth severance activity that occurred for the two significant programs described above. The balances are included in accrued liabilities.

-18-

The other adjustments in 2014 were due to changes in estimates, including an impact of forfeited severance amounts. We expect the majority of the liabilities for these programs to be paid in the first half of fiscal 2015.

We expect to incur additional severance, restructuring, and acquisition integration costs in 2015 of approximately $12 million as a result of the activities discussed above.

We continue to review our business strategies and evaluate potential new restructuring actions. This could result in additional restructuring costs in future periods.

-19-

The carrying values of our long-term debt and other borrowing arrangements were as follows:

Revolving Credit Agreement due 2018

Our revolving credit agreement provides a $400 million multi-currency asset-based revolving credit facility (the Revolver). The borrowing base under the Revolver includes eligible accounts receivable; inventory; and property, plant, and equipment of certain of our subsidiaries in the U.S., Canada, Germany, the Netherlands, and the UK. In January 2015, we borrowed $200.0 million under the Revolver in order to fund a portion of the purchase price for the acquisition of Tripwire (see Note 2). As of March 29, 2015, our available borrowing capacity was $114.0 million. The Revolver matures in 2018. Interest on outstanding borrowings is variable, based upon LIBOR or other similar indices in foreign jurisdictions, plus a spread that ranges from 1.25% - 1.75%, depending upon our leverage position. We pay a commitment fee on our available borrowing capacity of 0.375%. In the event we borrow more than 90% of our borrowing base, we are subject to a fixed charge coverage ratio covenant.

Variable Rate Term Loan due 2020

In 2013, we borrowed $250.0 million under a Term Loan Credit Agreement (the Term Loan). The Term Loan is secured on a second lien basis by the assets securing the Revolving Credit Agreement due 2018 discussed above and on a first lien basis by the stock of certain of our subsidiaries. The borrowings under the Term Loan are scheduled to mature in 2020 and require quarterly amortization payments of approximately $0.6 million. The first payment in 2015 is due on March 31, 2015, in our second fiscal quarter. Interest under the Term Loan is variable, based upon the three-month LIBOR plus an applicable spread. The interest rate as of March 29, 2015 was 3.25%. We paid approximately $3.9 million of fees associated with the Term Loan, which are being amortized over the life of the Term Loan using the effective interest method.

Senior Subordinated Notes

In June 2014, we issued $200.0 million aggregate principal amount of 5.25% senior subordinated notes due 2024 (the 2024 Notes). The 2024 Notes are guaranteed on a senior subordinated basis by certain of our subsidiaries. The 2024 Notes rank equal in right of payment with our senior subordinated notes due 2023, 2022 and 2019 and with any future subordinated debt, and they are subordinated to all of our senior debt and the senior debt of our subsidiary guarantors, including our Term Loan and Revolver. Interest is payable semiannually on January 15 and July 15 of each year. We paid approximately $4.2 million of fees associated with the issuance of the 2024 Notes, which are being amortized over the life of the 2024 Notes using the effective interest method. We used the net proceeds from the transaction for general corporate purposes.

In March 2013, we issued €300.0 million ($388.2 million at issuance) aggregate principal amount of 5.5% senior subordinated notes due 2023 (the 2023 Notes). In November 2014, we issued an additional €200.0 million ($247.5 million at issuance) aggregate principal amount of 2023 Notes. The carrying value of the 2023 Notes as of March 29, 2015 is $555.3 million. The 2023 Notes are guaranteed on a senior subordinated basis by certain of our subsidiaries. The notes rank equal in right of payment with our senior subordinated notes due 2024, 2022, and 2019 and with any future subordinated debt, and they are subordinated to all of our senior debt and the senior debt of our subsidiary guarantors, including our Term Loan and Revolver. Interest is payable semiannually on April 15 and October 15 of each year. We paid $12.6 million of fees associated with the issuance of the 2023 Notes, which are being amortized over the life of the notes using the effective interest method. We used the net proceeds from the transactions to repay amounts outstanding under the revolving credit component of our previously outstanding Senior Secured Facility and for general corporate purposes.

We have outstanding $700.0 million aggregate principal amount of 5.5% senior subordinated notes due 2022 (the 2022 Notes). The 2022 Notes are guaranteed on a senior subordinated basis by certain of our subsidiaries. The 2022 Notes rank equal in right of payment with our senior subordinated notes due 2024, 2023, and 2019, and with any future subordinated debt, and they are subordinated to all of our senior debt and the senior debt of our subsidiary guarantors, including our Term Loan and Revolver. Interest is payable semiannually on March 1 and September 1 of each year.

We have outstanding $5.2 million aggregate principal amount of our senior subordinated notes due 2019 (the 2019 Notes). The 2019 Notes have a coupon interest rate of 9.25% and an effective interest rate of 9.75%. The interest on the 2019 Notes is payable semiannually on June 15 and December 15. The 2019 notes are guaranteed on a senior subordinated basis by certain of our subsidiaries. The notes rank equal in right of payment with our senior subordinated notes due 2024, 2023, and 2022, and with any future senior subordinated debt, and are subordinated to all of our senior debt and the senior debt of our subsidiary guarantors, including our Term Loan and Revolver.

Fair Value of Long-Term Debt

The fair value of our senior subordinated notes as of March 29, 2015 was approximately $1,510.9 million based on quoted prices of the debt instruments in inactive markets (Level 2 valuation). This amount represents the fair values of our senior subordinated notes with a carrying value of $1,460.6 million as of March 29, 2015. We believe the fair value of our Revolver and Term Loan approximates book value.

Income tax expense was $0.7 million for the three months ended March 29, 2015, representing an effective tax rate of (3.6%). While we recognized a loss from continuing operations before taxes, we recognized income tax expense primarily because our full year forecasted effective tax rate on full year forecasted pre-tax income is a negative rate (an income tax benefit) as a result of implemented tax planning strategies. The tax benefit stems from being able to recognize a significant balance of foreign tax credits related to one of our foreign jurisdictions. The negative effective tax rate results in recognizing income tax expense in an interim period with a pre-tax loss.

In addition, in the three months ended March 29, 2015, we recognized a $1.5 million tax benefit as a result of reducing a deferred tax valuation allowance related to a capital loss carryforward. Based on transactions in the three months ended March 29, 2015, the capital loss carryforward has become fully realizable.

In July 2011, our Board of Directors authorized a share repurchase program, which allows us to purchase up to $150.0 million of our common stock through open market repurchases, negotiated transactions, or other means, in accordance with applicable securities laws and other restrictions. In November 2012, our Board of Directors authorized an extension of the share repurchase program, which allows us to purchase up to an additional $200.0 million of our common stock. This program is funded by cash on hand and cash flows from operating activities. The program does not have an expiration date and may be suspended at any time at the discretion of the Company.

For the three months ended March 29, 2015, we did not repurchase any of our common stock under the share repurchase program. From inception of the program to March 29, 2015, we have repurchased 6.7 million shares of our common stock under the program for an aggregate cost of $310.9 million and an average price of $46.54.

Overview

Belden Inc. (the Company, us, we, or our) is an innovative signal transmission solutions company built around five global business platforms – Broadcast Solutions, Enterprise Connectivity Solutions, Industrial Connectivity Solutions, Industrial IT Solutions, and Network Security Solutions. Our comprehensive portfolio of signal transmission solutions provides industry leading secure and reliable transmission of data, sound and video for mission critical applications.

We strive for operational excellence through the execution of our Belden Business System, which includes three areas of focus: Lean enterprise initiatives, our Market Delivery System, and our Talent Management System. Through operational excellence we generate significant free cash flow on an annual basis. We utilize the cash flow generated by our business to fuel our continued transformation and generate shareholder value. We believe our business system, balance across markets and geographies, systematic go-to-market approach, extensive portfolio of innovative solutions, commitment to Lean principles, and improving margins present a unique value proposition for shareholders.

We use a set of tools and processes that are designed to continuously improve business performance in the critical areas of quality, delivery, cost, and innovation. We consider revenue growth, Adjusted EBITDA margin, free cash flows, and return on invested capital to be our key operating performance indicators. We also seek to acquire businesses that we believe can help us achieve these objectives. The extent to which appropriate acquisitions are made and integrated can affect our overall growth, operating results, financial condition, and cash flows.

Trends and Events

The following trends and events during 2015 have had varying effects on our financial condition, results of operations, and cash flows.

Commodity prices

Our operating results can be affected by changes in prices of commodities, primarily copper and compounds, which are components in some of the products we sell. Generally, as the costs of inventory purchases increase due to higher commodity prices, we raise selling prices to customers to cover the increase in costs, resulting in higher sales revenue but a lower gross profit percentage. Conversely, a decrease in commodity prices would result in lower sales revenue but a higher gross profit percentage. Selling prices of our products are affected by many factors, including end market demand, capacity utilization, overall economic conditions, and commodity prices. Importantly, however, there is no exact measure of the effect of changing commodity prices, as there are thousands of transactions in any given quarter, each of which has various factors involved in the individual pricing decisions. Therefore, all references to the effect of copper prices or other commodity prices are estimates.

Channel Inventory

Our operating results also can be affected by the levels of Belden products purchased and held as inventory by our channel partners and customers. Our channel partners and customers purchase and hold our products in their inventory in order to meet the service and on-time delivery requirements of their customers. Generally, as our channel partners and customers change the level of Belden products owned and held in their inventory, it impacts our revenues. Comparisons of our results between periods can be impacted by changes in the levels of channel inventory. We are dependent upon our channel partners to provide us with information regarding the amount of our products that they own and hold in their inventory. As such, all references to the effect of channel inventory changes are estimates.

Market Growth and Market Share

The broadcast, enterprise, industrial, and network security markets in which we operate can generally be characterized as highly competitive and highly fragmented, with many players. Based on available data for our served markets, we estimate that our market share ranges from approximately 5% - 20%. A substantial acquisition in one of our served markets would be necessary to meaningfully change our estimated market share percentage. We monitor available data regarding market growth, including independent market research reports, publicly available indices, and the financial results of our direct and indirect peer companies, in order to estimate the extent to which our served markets grew or contracted during a particular period. We expect that our unit sales volume will increase or decrease consistently with the market growth rate. Our strategic goal is to utilize our Market Delivery System to target faster growing geographies, applications, and trends within our end markets, in order to achieve growth that is higher than the general market growth rate. To the extent that we exceed the market growth rates, we consider it to be the result of capturing market share.

Acquisitions

We completed the acquisitions of Tripwire Inc. (Tripwire) on January 2, 2015; Coast Wire & Plastic Tech., LLC (Coast) on November 20, 2014; ProSoft Technology, Inc. (ProSoft) on June 11, 2014; and Grass Valley USA, LLC and GVBB Holdings S.a.r.l. (collectively, Grass Valley), on March 31, 2014. The results of Tripwire, Coast, ProSoft, and Grass Valley have been included in our Consolidated Financial Statements from their respective acquisition dates and are reported in the Network Security, Industrial Connectivity, Industrial IT, and Broadcast segments, respectively.

Productivity Improvement Program and Acquisition Integration

In 2014, we began a productivity improvement program and the integration of our acquisition of Grass Valley. The productivity improvement program is focused on improving the productivity of our sales, marketing, finance, and human resources functions relative to our peers. The majority of the costs for the productivity improvement program relate to the Industrial Connectivity, Enterprise, and Industrial IT segments. The restructuring and integration activities related to our acquisition of Grass Valley are focused on achieving desired cost savings by consolidating existing and acquired operating facilities and other support functions. The Grass Valley costs relate to our Broadcast segment. In the three months ended March 29, 2015 and March 30, 2014, we recorded severance, restructuring, and integration costs of $14.5 million and $2.3 million, respectively, related to these two significant programs, as well other cost reduction actions and the integration of our acquisitions of ProSoft, Coast, and Tripwire. The other restructuring and integration costs primarily consisted of costs of integrating manufacturing operations, such as relocating inventory on a global basis, retention bonuses, relocation, travel, reserves for inventory obsolescence as a result of product line integration, costs to consolidate operating and support facilities, and other costs.

We expect to incur approximately $12 million of severance, restructuring, and integration costs in the remainder of 2015 related to these programs. We expect the productivity improvement program to reduce our operating expenses by approximately $18 million on an annualized basis. We are substantially realizing such benefits.

We continuously review our business strategies. In order to remain competitive, our goal is to improve productivity on an annual basis. To the extent that market growth rates are low, we may need to restructure aspects of our business in order to meet our annual productivity targets. This could result in additional restructuring costs in future periods. The magnitude of restructuring costs in the future could be influenced by statutory requirements in the countries in which we operate and our internal policies with regard to providing severance benefits in the absence of statutory requirements.

Off-Balance Sheet Arrangements

We have no off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial condition, results of operations, or cash flows that are or would be considered material to investors.

Critical Accounting Policies

During the three months ended March 29, 2015:

We have certain products subject to the accounting guidance on software revenue recognition. For such products, software license revenue is recognized when persuasive evidence of an arrangement exists, delivery of the product has occurred, the fee is fixed or determinable, collection is probable and vendor-specific objective evidence (VSOE) of the fair value of undelivered elements exists. As substantially all of the software licenses are sold in multiple-element arrangements that include either support and maintenance or both support and maintenance and professional services, we use the residual method to determine the amount of software license revenue to be recognized. Under the residual method, consideration is allocated to undelivered elements based upon VSOE of the fair value of those elements, with the residual of the arrangement fee allocated to and recognized as software license revenue. In our Network Security Solutions segment, we have established VSOE of the fair value of support and maintenance, subscription-based software licenses and professional services. Software license revenue is generally recognized upon delivery of the software if all revenue recognition criteria are met.

Revenue allocated to support services under our Network Security Solutions support and maintenance contracts, subscription-based software, and remote ongoing operational services is paid in advance and recognized ratably over the term of the service. Revenue allocated to professional services, including remote implementation services, is recognized as the services are performed.

Results of Operations

Consolidated Income from Continuing Operations before Taxes

-26-

Revenues increased in the three months ended March 29, 2015 from the comparable period of 2014 due to the following factors:

Gross profit for the three months ended March 29, 2015 included $1.4 million of severance, restructuring, and acquisition integration costs and $0.3 million of cost of sales arising from the adjustment of inventory to fair value related to our November 2014 acquisition of Coast. Excluding those costs, gross profit for the three months ended March 29, 2015 increased by $33.6 million from the comparable period of 2014 primarily due to acquisitions. Acquisitions contributed $45.2 million of gross profit in the three months ended March 29, 2015. The impact of acquisitions was partially offset by unfavorable currency translation of $10.6 million. In addition, the impact of unfavorable product mix, primarily in our Broadcast segment, was offset by improved productivity as a result of our completed restructuring activities.

Selling, general and administrative expenses increased in the three months ended March 29, 2015 from the comparable period of 2014 primarily due to our acquisitions. Grass Valley, ProSoft, Coast, and Tripwire recognized $35.1 million of selling, general and administrative expenses in the three months ended March 29, 2015. In addition, selling, general and administrative expenses increased in the three months ended March 29, 2015 due to an increase in severance, restructuring, and acquisition integration costs of $9.9 million compared to the prior year. We also recognized $9.2 million of compensation expense as a result of accelerating the vesting of certain acquiree equity awards at the closing of the Tripwire acquisition in the three months ended March 29, 2015. These increases were partially offset by favorable currency translation of $4.2 million and improved productivity of approximately $4.9 million as a result of our completed restructuring actions.

Research and development expenses increased in the three months ended March 29, 2015 from the comparable period of 2014 primarily due to our acquisitions. Grass Valley, ProSoft, Coast, and Tripwire recognized $16.3 million of research and development expenses in the three months ended March 29, 2015. In addition, research and development expenses increased in the three months ended March 29, 2015 due to an increase in severance, restructuring, and acquisition integration costs of $0.9 million compared to the prior year. These increases were partially offset by favorable currency translation of $1.9 million.

Amortization of intangibles increased in the three months ended March 29, 2015 from the comparable period of 2014 due to our acquisitions. Grass Valley, ProSoft, Coast, and Tripwire recognized $15.6 million of amortization of intangibles in the three months ended March 29, 2015. This increase was partially offset by favorable currency translation of $0.8 million.

Operating income decreased in the three months ended March 29, 2015 from the comparable period of 2014 due to the increases in selling, general and administrative expenses, research and development expenses, and amortization of intangibles discussed above, partially offset by the increase in gross profit.

Interest expense increased in the three months ended March 29, 2015 from the comparable period of 2014 due to the increase in our long-term debt balance as compared to March 30, 2014.

-27-

Income from continuing operations before taxes decreased to a loss in the three months ended March 29, 2015 from the comparable period of 2014 due to the decrease in operating income and increase in interest expense discussed above.

Income Taxes

We recognized income tax expense of $0.7 million for the three months ended March 29, 2015, representing an effective tax rate of (3.6%). While we recognized a loss from continuing operations before taxes, we recognized income tax expense primarily because our full year forecasted effective tax rate on full year forecasted pre-tax income is a negative rate (an income tax benefit) as a result of implemented tax planning strategies. The tax benefit stems from being able to recognize a significant balance of foreign tax credits related to one of our foreign jurisdictions. The negative effective tax rate results in recognizing income tax expense in an interim period with a pre-tax loss.

In addition, in the three months ended March 29, 2015, we recognized a $1.5 million tax benefit as a result of reducing a deferred tax valuation allowance related to a capital loss carryforward. Based on transactions in the three months ended March 29, 2015, the capital loss carryforward has become fully realizable.

We recognized income tax expense of $5.7 million for the three months ended March 30, 2014, representing an effective tax rate of 18.4%. Our income tax expense for the three months ended March 30, 2014 included a $2.2 million tax benefit due to a reduction of an uncertain tax position liability. The liability was reduced as a result of favorable developments with a foreign tax audit.

Our income tax expense for the three months ended March 30, 2014 was also favorably impacted by foreign tax rate differences. The statutory tax rates associated with our foreign earnings generally are lower than the statutory U.S. tax rate of 35%. This had the greatest impact on our income from continuing operations before taxes that is generated in Germany, Canada, and the Netherlands, which have statutory tax rates of approximately 28%, 26%, and 25%, respectively. Foreign tax rate differences reduced our income tax expense by approximately $2.8 million for the three months ended March 30, 2014.

Our income tax expense and effective tax rate in future periods may be impacted by many factors, including our geographic mix of income and changes in tax laws.

Consolidated Adjusted Revenues and Adjusted EBITDA

Adjusted Revenues increased in the three months ended March 29, 2015 from the comparable period of 2014 due to the following factors:

-28-

Adjusted EBITDA increased in the three months ended March 29, 2015 from the comparable period of 2014 primarily due to acquisitions, which contributed $15.8 million of Adjusted EBITDA. In addition, Adjusted EBITDA increased due to improved productivity as a result of our recently completed restructuring activities and the increase in sales volume discussed above. These factors were partially offset by unfavorable product mix, particularly in the Broadcast segment. Further, unfavorable currency translation resulted in a $5.2 million decrease in Adjusted EBITDA.

Use of Non-GAAP Financial Information

Adjusted Revenues and Adjusted EBITDA are non-GAAP financial metrics. In addition to reporting financial results in accordance with accounting principles generally accepted in the United States, we provide these non-GAAP 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; revenue and cost of sales deferrals for certain acquired product lines subject to software revenue recognition accounting requirements; severance, restructuring, and acquisition integration costs; gains (losses) recognized on the disposal of businesses and tangible assets; amortization of intangible assets; depreciation expense; gains (losses) on debt extinguishment; discontinued operations; and other costs. 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. Adjusted results should be considered only in conjunction with results reported according to accounting principles generally accepted in the United States and may not be comparable to similarly titled measures presented by other companies. The following tables reconcile our non-GAAP financial metrics to our GAAP results.
