On July 21, 2026, GoPro, Inc. (the "Company") received a notice from The Nasdaq Stock Market ("Nasdaq") that the Company is not in compliance with Nasdaq's Listing Rule 5450(a)(1), as the minimum bid price of the Company's Class A Common Stock has been below $1.00 per share for thirty (30) consecutive business days. Pursuant to Nasdaq Marketplace Rule 5810(c)(3)(A), the Company has 180 calendar days to achieve compliance with the minimum bid price requirement. To regain compliance, the minimum bid price of the Company's common stock must meet or exceed $1.00 per share for a minimum of ten (10) consecutive business days during this 180 calendar day grace period.

This notification of noncompliance has no immediate effect on the listing or trading of the Company's Class A Common Stock on the Nasdaq Global Select Market under the symbol "GPRO".
