Premiere Global Services Revises 2005 Financial Outlook
Solid Growth in Core Business Practices Dampened by Weakness in Legacy Broadcast Fax

ATLANTA, GA, September 13, 2005 - Premiere Global Services, Inc. (NYSE: PGI), a global outsource provider of business communications services and business process solutions, today announced that it has lowered its financial outlook for the remainder of the year. The Company anticipates revenues in 2005 will be in the range of $494 to $498 million and diluted EPS from continuing operations will be in the range of $0.66 to $0.67 in 2005, excluding a pre-tax restructuring charge of approximately $2.0 million expected to be incurred during the third quarter as a result of cost-saving initiatives. The Company anticipates that cash flows from operating activities will total approximately $94 million in 2005.

"Our revised guidance reflects challenges that arose in the third quarter, in which we experienced unexpected fall-out from prolonged regulatory uncertainty concerning our legacy fax business and greater seasonal softness than expected," said Boland T. Jones, Founder, Chairman and CEO of Premiere Global Services, Inc. "We overcame the challenge faced earlier this year of replacing revenue from our largest conferencing customer, IBM, and our core business is experiencing solid growth. I am confident that we will manage through this situation. Our Company remains strong and I am excited about our future for a number of reasons:

First, we offer a compelling business value to our customers by applying innovative communication technologies that automate and simplify business processes in four core business practices: Conferencing and Collaboration, Notification Management, Marketing Automation and Document Management. We estimate the addressable market size for these services is over $10 billion* and growing, and we continue to experience double-digit annual growth in these core practice offerings. Unfortunately, we expect this growth will be offset in the second half of the year by a drop in legacy broadcast fax revenue of approximately 30% in North America from the same period in 2004, which is a significant increase in the rate of decline over recent years. We project that by the end of the year, our legacy North American broadcast fax business will represent less than 7% of consolidated revenues. This decrease is in addition to the previously announced expected decline of approximately $17 million in revenue from IBM also in the second half of 2005.

Second, our management team is focused on specific initiatives to increase our revenues and profitability. In the area of revenue growth, we are focused on continuing to embed our solutions into repetitive business processes, like service alerts, collections automation, electronic statement distribution and daily collaboration activities that we believe moves us up the value chain and produces more predictable revenue. Additionally, we have re-aligned our sales resources into four core business practices since the beginning of the year, and plan to continue to meaningfully improve sales productivity through more effective marketing support. In the area of profitability, we plan to accelerate our efforts to automate our internal service delivery and support activities to eliminate costs and to streamline procedures. In doing so, we hope to create a richer customer experience for our enterprise users. We believe these actions will result in significant cost savings beginning in the second half of next year.

Finally, our cash flow remains strong with $94 million of cash flows from operating activities expected this year. This cash flow gives us the flexibility to continue to invest in strategic growth opportunities, such as the recent acquisition of Netspoke and its Web collaboration platform, and in our Company's stock, where we have repurchased nearly 800,000 shares in this quarter alone."
