RSU Vesting and Share Dispositions by Bandwidth Inc.'s Principal Accounting Officer

According to the filing, Devin M. Krupka, who serves as Controller and Principal Accounting Officer of Bandwidth Inc. (NASDAQ:BAND), reported four transactions in the company's Class A Common Stock across two trading dates. On August 28, 2026, two separate tranches of restricted stock units vested: 2,775 units from a grant made on November 28, 2023, and 1,518 units from a grant made on November 28, 2024. Both conversions carried a price of $0, consistent with the nature of RSU settlements, as each restricted stock unit represents a contingent right to receive one share of Class A Common Stock.

The filing disclosed that the 2023 grant originally totaled 33,303 restricted stock units, with one third vesting on the first anniversary of the grant date and the remaining shares vesting in eight equal quarterly installments beginning February 28, 2025. The 2024 grant originally totaled 18,205 restricted stock units, structured similarly, with one third vesting on the first anniversary and the remainder vesting in eight equal quarterly installments beginning February 28, 2026.
