Polycom Announces Preliminary Financial Results for Q1 2012

PLEASANTON, Calif. – April 5, 2012 – Polycom, Inc. (NASDAQ: PLCM), the global leader in open standards-based unified communications (UC), today announced preliminary financial results for the first quarter of 2012.

The Company expects to report net revenues for the quarter ended March 31, 2012, in the range of $364 million to $370 million, compared with net revenues of $344 million in the first quarter of 2011.

“We estimate that we grew quarterly revenues approximately 7 percent year-over-year, with each region recording increases. However, the growth rate was below our overall expectations, driven primarily by shortfalls in Asia Pacific and North America,” said Andrew Miller, President and CEO. “Polycom’s current operating model assumes a higher level of revenue growth, and we will analyze our assumptions between now and our regularly scheduled call on April 18^th.”

The Company expects to report earnings per diluted share for the first quarter of 2012 in the range of $0.07 to $0.09 on a GAAP basis, compared with $0.19 per diluted share on a GAAP basis in the first quarter of 2011, and between $0.21 to $0.23 on a non-GAAP basis, compared with $0.24 on a non-GAAP basis per diluted share for the comparable period last year. The reconciliation of the preliminary range of GAAP net income per diluted share to the preliminary range of non-GAAP net income per diluted share for the three months ended March 31, 2012, and the reconciliation of GAAP net income per diluted share to non-GAAP net income per diluted share for the three months ended March 31, 2011, is provided at the end of this press release.

By region, the Company’s preliminary quarterly revenue results are:

Reconciliation of GAAP net income per diluted share to

Non-GAAP net income per diluted share

(Unaudited)

GAAP to non-GAAP Reconciliation

To supplement our consolidated financial statements presented on a GAAP basis, Polycom uses non-GAAP measures of operating results, net income and income per share, which are adjusted to exclude certain costs, expenses, gains, and losses we believe appropriate to enhance an overall understanding of our past financial performance and also our prospects for the future. These adjustments to our current period GAAP results are made with the intent of providing both management and investors a more complete understanding of Polycom’s underlying operational results and trends and our marketplace performance. For example, the non-GAAP results are an indication of our baseline performance before gains, losses, or other charges that are considered by management to be outside of our core operating results. In addition, these adjusted non-GAAP results are among the primary indicators management uses as a basis for our planning and forecasting of future periods. The presentation of this additional information is not meant to be considered in isolation or as a substitute for net income or diluted net income per share prepared in accordance with generally accepted accounting principles in the United States.
