Consolidated Operating Results

For the second quarter of 2014, revenue was $691.1 million compared to $672.7 million for the same quarter of 2013, an increase of 2.7 percent. Revenue from acquired entities⁴ was $8.8 million during the second quarter of 2014. The Company’s platform-based businesses¹ had revenue of $506.6 million in the second quarter of 2014, an increase of 2.4 percent over the same quarter of the previous year. Revenue from agent services¹ increased 4.2 percent in the second quarter of 2014 to $188.9 million compared to $181.2 million in the second quarter of 2013.

The Unified Communications segment had revenue of $411.9 million in the second quarter of 2014, an increase of 0.8 percent compared to the same quarter of the previous year. The increase in Unified Communications revenue included $4.7 million from SchoolMessenger. The Communication Services segment had revenue of $294.9 million in the second quarter of 2014, an increase of 8.7 percent compared to the second quarter of 2013. The increase in Communication Services revenue included $4.1 million from Health Advocate.

Adjusted EBITDA² for the second quarter of 2014 was $175.4 million compared to $180.7 million for the second quarter of 2013. EBITDA² was $171.5 million in the second quarter of 2014 compared to $178.5 million in the same quarter of the previous year. The decrease in EBITDA and adjusted EBITDA was due, in part, to a one-time benefit in the second quarter of 2013.

Adjusted operating income² for the second quarter of 2014 was $139.7 million, or 20.2 percent of revenue, compared to $150.8 million, or 22.4 percent of revenue in the same quarter of 2013, a decrease of 7.4 percent. Operating income was $121.9 million in the second quarter of 2014 compared to $134.7 million in the second quarter of 2013, a decrease of 9.5 percent. This decrease was primarily due to acquisition costs, the impact of foreign currency fluctuations and mark-to-market benefit plan costs in the second quarter of 2014 and a one-time benefit in the second quarter of 2013.

Adjusted net income² was $62.0 million in the second quarter of 2014, an increase of 2.2 percent from the same quarter of 2013. Net income increased to $47.8 million in the second quarter of 2014 from $43.7 million in the same quarter of 2013. The improvement in profitability was driven primarily by lower interest expense resulting from deleveraging and lower cost of debt.

Balance Sheet, Cash Flow and Liquidity

At June 30, 2014, West Corporation had cash and cash equivalents totaling $159.7 million and working capital of $264.3 million. Net interest expense was $48.4 million during the three months ended June 30, 2014 compared to $57.2 million during the comparable period the prior year.

The Company’s net debt to adjusted EBITDA ratio, as calculated pursuant to the Company’s senior secured term debt facilities⁵, was 4.59x at June 30, 2014.

On July 1, 2014, the Company issued $1.0 billion aggregate principal amount of 5.375 percent notes due 2022 (the “2022 Senior Notes”). A portion of the net proceeds from the 2022 Senior Notes was used to repurchase, pursuant to a tender offer, $270.8 million aggregate principal amount of the 8.625 percent Senior Notes due 2018 (the “2018 Senior Notes”) and $200.0 million aggregate principal amount of the 7.875 percent Senior Notes due 2019 (the “2019 Senior Notes”). The aggregate repurchase price for the 2018 Senior Notes was $298.7 million including accrued interest of $10.8 million and tender offer premium of $17.1 million. The aggregate repurchase price for the 2019 Senior Notes was $215.3 million including accrued interest of $2.0 million and tender offer premium of $13.3 million. The Company also used a portion of the net proceeds from the 2022 Senior Notes to repay a portion of the senior secured term loan facility due 2018. The total aggregate principal amount repaid on the senior secured term loan facility due 2018 was $250.0 million. On July 17, 2014, the Company redeemed the remaining $229.2 million aggregate principal amount of the 2018 Senior Notes. The aggregate purchase price for these 2018 Senior Notes was $242.9 million including accrued interest of $0.1 million, a redemption premium of $9.9 million and a make whole premium of $3.7 million.

“The completion of the bond offering and the changes to the credit agreement have improved West’s capital structure,” said Paul Mendlik, CFO. “We were able to replace current long-term debt with extended maturities and a significantly more attractive rate, saving us approximately $38 million in annual cash interest expense. The full impact of these changes will be realized starting next year.”

During the second quarter of 2014, the Company invested $40.4 million, or 5.8 percent of revenue, in capital expenditures primarily for software, computer equipment, the consolidation of data centers and expansion of the Company’s network infrastructure.

Acquisitions

On April 21, 2014, the Company completed the acquisition of Reliance Holding, Inc., doing business as SchoolMessenger, a leading provider of notification and mobile communication solutions for the K-12 education market. The purchase price was approximately $76.5 million and was funded with cash on hand. Results from SchoolMessenger after April 21, 2014 are included in the Company’s Unified Communications operating segment.

On June 13, 2014, the Company completed the acquisition of Health Advocate, Inc., a leading provider of healthcare advocacy services. The purchase price was approximately $265.4 million and was funded with cash on hand and use of the Company’s revolving trade accounts receivable financing facility. Results from Health Advocate after June 13, 2014 are included in the Company’s Communication Services operating segment.

Updated 2014 Guidance

The Company had originally provided 2014 guidance with the release of its fourth quarter 2013 results on January 30, 2014. A portion of the original guidance was updated on June 16, 2014 to include the expected results from the acquisitions of SchoolMessenger and Health Advocate. That update has not changed and is included in the table below. The acquisitions are expected to result in higher revenue and adjusted EBITDA. The impact of increased amortization from these acquisitions is expected to result in slightly lower operating income.

The Company has updated a portion of its 2014 guidance today to include its revised expectations for the remainder of 2014 and the impact of its recent debt refinancing. The refinancing is expected to result in a net decrease in net income of approximately $42 million and diluted earnings per share of approximately $0.49 in 2014 due to accelerated bond amortization, and bond redemption, tender offer and make-whole premiums. This decrease is net of interest savings of approximately $9 million.

Interest savings and add-backs for amortization related to acquisitions and accelerated bond amortization, and bond redemption, tender offer, and make-whole premiums on the called bonds are expected to result in slightly higher adjusted net income and adjusted diluted earnings per share. Cash flows from operations are expected to increase mainly due to the tax benefits of the refinancing transactions.

The updated guidance below assumes no additional acquisitions or changes in the current operating environment.

Reconciliation of Non-GAAP Financial Measures

Adjusted Operating Income Reconciliation

Adjusted operating income is not a measure of financial performance under generally accepted accounting principles (“GAAP”). The Company believes adjusted operating income provides a relevant measure of operating profitability and a useful basis for evaluating the ongoing operations of the Company. Adjusted operating income is used by the Company to assess operating income before the impact of IPO-related expenses, expenses terminated in connection with the IPO, M&A and acquisition-related costs and certain non-cash items. Adjusted operating income should not be considered in isolation or as a substitute for operating income or other profitability data prepared in accordance with GAAP. Adjusted operating income, as presented, may not be comparable to similarly titled measures of other companies. Set forth below is a reconciliation of adjusted operating income to operating income.

11

Adjusted Net Income and Adjusted Earnings per Share Reconciliation

Adjusted net income and adjusted earnings per share (EPS) are non-GAAP measures. The Company believes these measures provide a useful indication of profitability and basis for assessing the operations of the Company without the impact of IPO-related expenses, expenses terminated in connection with the IPO, bond redemption premiums, M&A and acquisition related costs and certain non-cash items.

Adjusted net income should not be considered in isolation or as a substitute for net income or other profitability metrics prepared in accordance with GAAP. Adjusted net income, as presented, may not be comparable to similarly titled measures of other companies.

Set forth below is a reconciliation of adjusted net income to net income.

12

Free Cash Flow Reconciliation

The Company believes free cash flow provides a relevant measure of liquidity and a useful basis for assessing the Company’s ability to fund its activities, including the financing of acquisitions, debt service, stock repurchases and distribution of earnings to shareholders. Free cash flow is calculated as cash flows from operations less cash capital expenditures. Free cash flow is not a measure of financial performance under GAAP. Free cash flow should not be considered in isolation or as a substitute for cash flows from operations or other liquidity measures prepared in accordance with GAAP. Free cash flow, as presented, may not be comparable to similarly titled measures of other companies. Set forth below is a reconciliation of free cash flow to cash flows from operations.

EBITDA and Adjusted EBITDA Reconciliation

The common definition of EBITDA is “earnings before interest expense, taxes, depreciation and amortization.” In evaluating liquidity and performance, the Company uses earnings before interest expense, share based compensation, taxes, depreciation and amortization, M&A and acquisition-related costs and one-time IPO-related expenses, or “adjusted EBITDA.” EBITDA and adjusted EBITDA are not measures of financial performance or liquidity under GAAP. EBITDA and adjusted EBITDA should not be considered in isolation or as a substitute for net income, cash flows from operations or other income or cash flows data prepared in accordance with GAAP. EBITDA and adjusted EBITDA, as presented, may not be comparable to similarly titled measures of other companies. EBITDA and adjusted EBITDA are used by certain investors as measures to assess the Company’s ability to service debt. Adjusted EBITDA is also used in the Company’s debt covenants, although the precise adjustments used to calculate adjusted EBITDA included in the Company’s credit facility and indentures vary in certain respects among such agreements and from those presented below. Certain adjustments to adjusted EBITDA were excluded from the calculations below consistent with the adjustments made for adjusted operating income and adjusted net income. Set forth below is a reconciliation of EBITDA and adjusted EBITDA to cash flows from operations and net income.
