On February 23, 2017, our common stock was delisted from the Nasdaq Capital Market due to our failure to comply with Nasdaq’s Listing Rule 5550(b)(1), which requires that we maintain $2.5 million in stockholders’ equity for continued listing (or meet the alternatives of market value of listed securities of $35 million or net income from continuing operations). NASDAQ had granted us a grace period through February 10, 2017, to regain compliance with Listing Rule 5550(b)(1), but we were unable to regain compliance within such period. Commencing on February 23, 2017, our common stock was quoted on the OTCQB under the symbol “ACUR”, however commencing June 4, 2018 and lasting until July 2, 2018 it was quoted on the OTC Markets OTC Pink tier. The downgrade was a result of the late filing of our 2017 Annual Report on Form 10-K beyond any applicable grace periods.
