On October 2, 2017, Oncobiologics, Inc. (the “Company”) received written notification from Nasdaq indicating that the Company was not in compliance with the rules for continued listing set as set forth in Nasdaq Marketplace Rule 5620(a), because the Company has not yet held an annual meeting of shareholders within twelve months of the end of the Company’s fiscal year end. The notification has no immediate effect on the listing of the Company’s common stock on the Nasdaq Global Market.

Under Nasdaq rules, the Company will have 45 calendar days from the date of the notification to submit a plan to regain compliance, and if Nasdaq accepts the plan, Nasdaq can grant an exception of up to 180 calendar days from fiscal year end, or until March 29, 2018 to regain compliance. If Nasdaq does not accept the Company’s plan, the Company may, at that time, request a hearing to remain on the Nasdaq Global Market, which request will ordinarily suspend such delisting determination until a decision by Nasdaq subsequent to the hearing.

On September 29, 2017, the Company filed a definitive proxy statement on Schedule 14A with the Securities and Exchange Commission for an Annual Meeting of Stockholders to be held on October 26, 2017 (the “Meeting”) to vote on the proposals described therein. While there can be no assurance that the Company will be successful in regaining compliance with the continued listing requirements and maintaining its listing of the Company’s common stock on the Nasdaq Global Market, the Company expects that upon completion of the Meeting, it will be in compliance with Nasdaq Marketplace Rule 5620(a).
