DENVER, Colo., May 9, 2017 —  TeleTech Holdings, Inc. (NASDAQ: TTEC), a leading global provider of customer experience, engagement, and growth solutions delivered through a proprietary, end-to-end Customer Engagement as a Service offering, today announced financial results for the first quarter ended March 31, 2017.

“The Company’s key financial metrics increased year-over-year, including bookings, revenue, operating income, net income, cash flow from operations, and earnings per share. The sales execution and profit enhancement strategies we implemented in 2016 are paying off as evidenced by our first quarter results,” commented Ken Tuchman, chairman and chief executive officer of TeleTech. “In addition, in early April 2017, we completed the strategic acquisition of the healthcare services company Connextions from OptumHealth. This acquisition continues to advance our healthcare footprint with increased diversification in our client base and offerings and expands our existing healthcare platform.”

“Digital disruption is driving a seismic shift from a product economy to a service economy. In this new world, engagement — the ability to attract, acquire, nurture, retain and grow authentic, long-term customer relationships — is the currency for growth. Our Customer Engagement as a Service offering provides insight-driven consulting, technology and operations to deliver contextual, seamless experiences within and across channels. Built on a unified delivery methodology, we are helping clients consistently increase revenue, reduce costs, and build lasting customer loyalty with humanity at the core of every interaction, whether live or digital,” continued Tuchman.

“We are consistently driving increased shareholder value across our business. From increasing our semi-annual dividend and continued share repurchases, to making targeted acquisitions, innovating our offerings and improving efficiencies, we are focused on growing shareholder value for today and into the future,” Tuchman concluded.
