On September 19, 2017, Aviragen Therapeutics, Inc. (the “Company”) received a notification from the Listing Qualifications Department of The NASDAQ Stock Market LLC (“Nasdaq”) that its application to transfer its common stock from The Nasdaq Global Select Market (the “Global Select Market”) to The Nasdaq Capital Market (the “Capital Market”) has been approved. At the opening of business on September 21, 2017, trading in the Company’s common stock will be transferred to the Capital Market. The Company's common shares will continue to trade on Nasdaq under the symbol "AVIR." This transfer to the Capital Market should not affect the trading of the Company's common stock. The Capital Market is a continuous trading market that operates in substantially the same manner as the Global Select Market, but with less stringent listing requirements.

As previously reported, on March 28, 2017, the Company received a letter from the staff (the “Staff”) of Nasdaq providing notification that, for the previous 30 consecutive business days, the bid price for the Company’s common stock had closed below the minimum $1.00 per share requirement for continued listing on the Global Select Market under Nasdaq Listing Rule 5450(a)(1). In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was provided an initial period of 180 calendar days, or until September 25, 2017, to regain compliance with the minimum bid price requirement. The Company now expects to be granted an additional 180 calendar day period to regain compliance, which will commence on September 26, 2017. The Company intends to monitor the bid price of its common stock and other continued listing standards on the Capital Market and will consider options available to it to achieve compliance with the minimum bid price requirement in this additional 180 calendar day period.
