BUSINESS OUTLOOK

“The race is on for companies across the globe to deliver experiences that set them apart from their competition. Forward thinking, value-oriented brands are increasingly selecting TeleTech as their go-to-partner for customer experience transformation,” commented Regina Paolillo, chief financial and administrative officer of TeleTech. “The accelerating growth rate of our emerging businesses is confirmation of the market demand for innovative approaches to customer experience. With continued growth in bookings alongside new product launches and an expanding international footprint, we expect to continue to advance our progress in transforming our financial model with higher revenue growth rates and operating margins.”

Paolillo continued, “We estimate a 2016 constant currency revenue growth rate between 6.75 and 7.50 percent, which assumes an estimated three percentage points of adverse impact from foreign exchange rate movements. Our emerging Customer Strategy, Technology and Growth businesses are estimated to collectively grow revenue in the low to mid double digits, while our Customer Management business will be in the low to mid single digits, before adjusting for an approximate three percent adverse impact from foreign exchange. We expect 46 percent of our revenue and operating income in the first half of 2016 with the balance in the second half.”

TeleTech full year 2016 guidance as follows:

·         Revenue — GAAP revenue estimated between $1.335 and $1.345 billion, reflecting an approximate three percent adverse impact from foreign exchange rate movements.

·         Operating Income Margin — GAAP operating income margin estimated to range between 8.1 and 8.3 percent, reflecting an approximate 20 basis points adverse impact from foreign exchange movements.

·         Capital Expenditures — Capital expenditures are estimated to approximate 4.5 percent of revenue.

NON-GAAP FINANCIAL MEASURES

To supplement the Company’s consolidated financial statements presented in accordance with generally accepted accounting principles (GAAP) in the United States, the Company uses the following Non-GAAP financial measures: Free Cash Flow, Non-GAAP Revenue, Non-GAAP Income from Operations, Non-GAAP EBITDA and Non-GAAP EPS. Additionally our discussion of revenue and income from operations contain references to constant currency amounts. Constant currency measures are calculated by translating the current year reported amounts using the prior year foreign exchange rates for each underlying currency. TeleTech believes that providing these Non-GAAP financial measures provides investors with greater transparency to the information used by TeleTech’s management in its financial and operational decision making and allows investors to see TeleTech’s results “through the eyes” of management. TeleTech also believes that providing this information better enables TeleTech’s investors to understand its operating performance and information used by management to evaluate and measure such performance. These financial measures are not intended to be used in isolation or as a substitute for the financial information prepared and presented in accordance with GAAP. A reconciliation of these Non-GAAP financial measures is available in the financial tables attached to this press release.
