Bandwidth announced that it has repurchased approximately $20.8 million aggregate principal amount of its 0.50% Convertible Senior Notes due 2028 (the “Notes”) in open-market transactions (the “Repurchases”) at a discount to par value.

The repurchase price payable by Bandwidth will be paid in cash.

The information furnished with this Item 8.01 shall not be deemed “filed” for purposes of Section 18 of the Exchange Act, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference into any filing under the Securities Act, except as expressly set forth by specific reference in such a filing.
