Hello everyoneand welcome to the 2026 Annual Meeting of Stockholders of Ribbon Communications Inc.

Please note that today's meeting is being recorded. Today's meeting will be conducted in the order specified in the agenda, which you will find on the virtual meeting webpage.

We will collect the questions and address them during the Q&A session at the end of today's meeting. Please limit yourself to two questions. I would like to remind everyone that our conversation today may include information that constitutes forward-looking statements. Such statements involve a number of risks, uncertainties, and other factors that could cause actual results to differ materially from these forward-looking statements as a result of various important factors, including those discussed in the Risk Factors section of our most recent annual report on Form 10-K, which is on file with the SEC and also available on the investor relations portion of our website. In addition, these forward-looking statements represent the company's expectations only as of today, and we assume no obligation to update them. I would now like to introduce Bruce McClelland, President and Chief Executive Officer of Ribbon Communications, who will be the chair of today's meeting. Thank you Patrick and good morning ladies and gentlemen. I hereby call the Ribbon 2026 Annual Meeting of Stockholders to order. Before proceeding with the business of the meeting, I'd also like to introduce you to the other board members of the company who are with us virtually today. Shaul Shani, Stewart Ewing Jr., Bruns Grayson, Beatriz Infante, Scott Mahir, Lou Silver, Rick Smith, and Tanya Timone. In addition to the directors attending virtually, there are a couple others that I'd like to also introduce. First, Ivonne Ingari and Zach Barnes from Deloitte & Touche, the company's independent auditor, who will be available to answer questions. In addition, also attending virtually is Anna Hogberg Seto, who is serving as our Inspector of Election for today's meeting. The Inspector has signed the customary oath of office to execute her duties with strict impartiality, and the oath will be filed with the records of the meeting. The Corporate Secretary will also file the proof of mailing of notice of the meeting with the records of the meeting. All stockholders of record at the close of business on April 6th, 2026, or holders of a valid proxy, are entitled to vote at the meeting. A complete list of the holders of record of the outstanding shares of the company's common stock on the record date for the meeting is available on the virtual meeting website. I've been informed by the Inspector of Election that a quorum is present. Accordingly, the meeting has been duly constituted for the transaction of business, and we will now proceed to vote on the five items of business before the meeting. One, the election of directors. Two, the ratification of appointment of Deloitte & Touche to serve as the company's independent registered public accounting firm for 2026. Three, the approval on a non-binding advisory basis of the compensation of our named executive officers. The board recommends the stockholders vote for each of these proposals. If you wish to vote and you haven't already, please vote now. The polls will close in approximately 30 seconds. As Patrick previously mentioned, you do not need to vote electronically if you have already sent in your signed proxy or if you have voted by telephone or internet. We will pause to allow for any additional votes before closing the polls. The polls are now closed for voting. Patrick, would you please report the voting results? I've received a preliminary report from the Inspector of Election, which states that the votes have been counted and, first, each of Stewart Ewing Jr., Bruns Grayson, Beatriz Infante, Scott Mair, Bruce McClelland, Shaul Shani, Lou Silver, Rick Smith, and Tanya Tamone have been reelected as directors. Second, the appointment of Deloitte & Touche to serve as Ribbon Communications' independent registered public accounting firm for the fiscal year ending December 31st, 2026 has been ratified. Finally, the compensation of the company's named executive officers has been approved on an advisory non-binding basis. The final tally of the votes will be published within four business days in a current report on Form 8-K to be filed with the U.S. Securities and Exchange Commission. Great. Thank you Patrick for that report. This concludes the formal business to come before the meeting, and I now declare the meeting adjourned. With our official business completed, we're happy to entertain any questions or comments that you may have regarding the company that have been submitted using the chat feature. Please note that we will only be answering questions that are within the parameters of the rules of conduct. While we're polling for questions, I'd like to highlight a few key points about Ribbon's business and why we are a compelling investment opportunity. First, we're at the foundation of mission-critical networks across the globe, providing service providers, enterprises, energy and transportation providers, and government and defense agencies with secure communications and networking solutions. Second, Ribbon is directly participating in the AI super cycle in a number of ways. Our portfolio of optical and IP networking products are designed to handle the massive data demands from the growing number of data centers and the follow-on growth in traffic as enterprises and consumers embrace AI applications on a daily basis. Our cloud-native secure voice solutions provide the on-ramp for agentic AI applications to access traditional telecom services. Ultimately, we aim to be at the center of the AI communications ecosystem, highlighted by the recent announcements with AWS and Salesforce. We've also developed our own Agentic AIOps platform called Acumen that is targeted at enabling our customers to simplify and automate the management of their increasingly complex networks. Finally, Ribbon has a solid financial foundation with durable cash flow, supported by a large base of high-margin, recurring support and maintenance revenue, and a strong mix of software with growing recurring subscription revenue. Given that context, we are excited about the future prospects for the company. It seems we have no questions in the queue. I would like to thank you all for attending our annual meeting of stockholders and for the support you've given us. Have a great day. The conference has now concluded. Thank you for attending today's presentation. You may now disconnect.
