**PART III - NARRATIVE**

State below in reasonable detail why Form 10-K, 20-F, 11-K, 10-Q, 10-D, N-CEN, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.

As of December 31, 2022, Ribbon Communications Inc. (the "Company") was in compliance with all covenants under its Senior Secured Credit Facilities Credit Agreement, as amended (the "2020 Credit Facility"), which the Company entered into on March 3, 2020. The Company is presently engaged in discussions with the lenders under the 2020 Credit Facility, regarding a new amendment to the 2020 Credit Facility to, among other things, increase the total net leverage ratio and decrease the minimum fixed charge coverage ratio included as covenants under the 2020 Credit Facility, for certain periods ending on or after March 31, 2023. The amendment, if completed, together with a pay down of a portion of the debt outstanding under the 2020 Credit Facility that would be required by the amendment, is expected to provide the Company with additional financial flexibility for 2023 as the Company targets continued improved profitability. The amendment will require material updates to the Company's disclosures in its Annual Report on Form 10-K (the "Form 10-K") for the year ended December 31, 2022. The Company's management team is working diligently on obtaining the amendment and therefore cannot complete the procedures necessary for filing the Form 10-K without unreasonable effort and expense. The Company currently anticipates obtaining such amendment and filing the Form 10-K within the time period proscribed in Rule 12b-25 promulgated under the Securities Exchange Act of 1934, as amended (or by March 31, 2023). Completion of the amendment requires, among other things, the consent of the lenders holding a majority of the principal amount outstanding under the 2020 Credit Facility.

If so, attach an explanation of the anticipated change, both narratively and quantitatively, and, if appropriate, state the reasons why a reasonable estimate of the results cannot be made.

On February 15, 2023, the Company furnished a Current Report on Form 8-K with the Securities and Exchange Commission that included a press release including unaudited financial statements for the Company's fourth quarter and year ended December 31, 2022 and reporting a loss from operations of $48.3 million for its year ended December 31, 2022 and $117.8 million for its year ended December 31, 2021. The press release also reported a net loss of $98.1 million for the Company's year ended December 31, 2022 and $177.2 million for its year ended December 31, 2021. The Company does not expect any material changes to the financial results reported in the press release.

***Cautionary Note Regarding Forward-Looking Statements***

This Notification of Late Filing on Form 12b-25 contains "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. Words such as "expect," "will," "anticipates," "estimates" and variations of such words and similar future or conditional expressions are intended to identify forward-looking statements. These forward-looking statements include, but are not limited to, statements related to our expectations regarding our financial results and results of operations for the quarter and year ended December 31, 2022, and our beliefs and expectations regarding the amendment to the 2020 Credit Facility and the pay down of a portion of the debt outstanding under the 2020 Credit Facility, the timing of the completion of the amendment to the 2020 Credit Facility and the timing of filing of the Form 10-K, all of which reflect the Company's expectations based upon currently available information and data. Because such statements are based on the Company's current expectations and are not statements of fact, actual results may differ materially from those projected or estimated and you are cautioned not to place undue reliance on these forward-looking statements. These forward-looking statements are not guarantees of future performance, conditions or results, and involve a number of known and unknown risks, uncertainties, assumptions and other important factors, many of which are outside the Company's control, that could cause actual results or outcomes to differ materially from those discussed in the forward-looking statements. Additional information regarding these and other factors can be found in the Company's reports filed with the Securities and Exchange Commission, including, without limitation, its Annual Report on Form 10-K for the year ended December 31, 2021. The Company disclaims and does not undertake any obligation to update or revise any forward-looking statement in this report, except as required by applicable law or regulation.
