PLANO, Texas -- Ribbon Communications Inc. (Nasdaq: RBBN), a global provider of real-time communications software and IP optical transport solutions to service providers, enterprises, and critical infrastructure sectors, today announced its financial results for the fourth quarter and full year 2021.

Revenue for the fourth quarter of 2021 was $231 million, compared to $244 million for the fourth quarter of 2020. Revenue for 2021 was $845 million, compared to $844 million for 2020.

"While our financial results for 2021 did not meet our expectations, we continue to make progress on our strategy. Our IP Optical Networks sales grew 22% sequentially in the fourth quarter and full year revenue in North America grew 164% year over year. We had several new wins with major carriers that we expect to begin to contribute in the second half of 2022. In our Cloud & Edge business, our increased focus on Enterprise is yielding results with sales nearly doubling in the fourth quarter both sequentially and year over year. Additionally, we had our first significant Telco Cloud win in the quarter," noted Bruce McClelland, President and Chief Executive Officer of Ribbon Communications.

McClelland continued, "As we enter 2022, we project 10%+ full year revenue growth in IP Optical Networks. Given the substantial growth opportunity presented by this business amidst a strong demand backdrop, we remain committed to the higher investment level needed to evolve the portfolio and capture share in future years. Our first quarter guidance accounts for continued supply chain delivery and cost issues affecting many industry participants, and increased uncertainty related to the conflicts in the Ukraine and Russia regions that are important markets for us."

Cash, cash equivalents and restricted cash was $106 million at December 31, 2021, compared with $104 million at September 30, 2021. GAAP Net loss of $96 million in the fourth quarter of 2021 includes a non-cash $116 million goodwill impairment charge related to revised projections for the IP Optical business segment, and a tax valuation allowance release of $28 million associated with the Company's U.S. tax position.

"To support our investment in critical growth areas, we are implementing a strategic restructuring to streamline operations. We expect to reduce our operating costs by approximately $5 million per quarter, incurring restructuring charges of about $6 million in employee separation costs and approximately $14 million in real estate optimization. We expect these savings to allow us to better align with the current demand environment and increase investment in key parts of the portfolio," said Mick Lopez, Chief Financial Officer of Ribbon Communications.
