As previously reported, on April 24, 2025, the Company received notification from the Staff indicating that the Company’s common stock was subject to potential delisting from The Nasdaq Global Select Market because, for a period of 30 consecutive business days, the bid price of the Company’s common stock had closed below the minimum $1.00 per share requirement for continued listing under the Bid Price Rule and that the Company had a period of 180 calendar days from the date of such notification, or until October 21, 2025, to regain compliance.
