AVAYA EMPLOYEE STOCK PURCHASE PLAN (ESPP) UPCOMING OFFERING PERIOD

ESPP Eligible Employees,

We are pleased to announce that the next offering period for Avaya’s Employee Stock Purchase Plan (ESPP) will begin December 1, 2021.

Avaya employees located in Australia, Brazil, Canada, Germany, Hungary, India, Ireland, Italy, Mexico, Singapore, the UAE, the UK and the U.S. continue to be eligible to participate.

As a reminder, the ESPP is a valuable opportunity to participate in Avaya’s success, allowing employees to make purchases of Avaya shares through accumulated payroll deductions at a discount to market prices. Essentially, it is another way to save for the future through regular contributions directly from your paycheck.

To participate in this upcoming offering period, eligible employees must enroll between November 1 and November 15, 2021 via Fidelity Stock Plan Services (Fidelity), our ESPP administrative services provider. If you are already enrolled in the plan and want to continue with your current election, no action is required. However, the window will be open for you to review and make changes. Increases to your contribution percentage are only allowed during an open enrollment window. Reductions to your contribution percentage can be made during an open enrollment window or during the first two months of an offering period and will be effective on the next available payroll or next offering period depending on when the election is modified.

Please be on the lookout for an e-mail from Fidelity with instructions for how to participate in Avaya’s ESPP, as well as how to set up your Fidelity account and review or change your contribution rate. In the meantime, please take time to review the video explaining how the ESPP works and read through the FAQ, Global Tax - Employee Information Supplement, Plan Document, Prospectus, Global Enrollment Agreement, and if applicable, the EU Information Supplement on Currents/@Work/Benefits & Money/ESPP.

We hope you choose to take part in this great opportunity!

Cheers,

Faye
