Sophiris Bio Announces Nasdaq Delisting

La Jolla, California, UNITED STATES

SAN DIEGO and VANCOUVER, British Columbia, March 10, 2020 (GLOBE NEWSWIRE) -- Sophiris Bio Inc. (NASDAQ: SPHS) (the "Company" or "Sophiris"), a biopharmaceutical company studying topsalysin (PRX302), a first-in-class, pore-forming protein, in late-stage clinical trials for the treatment of patients with urological diseases, today announced that on March 10, 2020, the Nasdaq Office of General Counsel notified the Company that the Nasdaq Hearing Panel (“Panel”) had determined to delist the Company’s shares from The Nasdaq Stock Market LLC (“Nasdaq”), and that trading in the Company’s common shares will be suspended effective at the open of business on March 12, 2020. Nasdaq will thereafter file a Form 25 with the Securities and Exchange Commission (“SEC”) to effect the formal delisting of the Company’s common stock following the expiration of all applicable Nasdaq procedures. Sophiris expects its common stock to be eligible for trading on the OTCQB also effective with the open of business on March 12, 2020 and to continue to trade under the symbol “SPHS”. 

As previously reported, the Nasdaq Staff determined to delist the Company’s common shares based on the Company’s non-compliance with the minimum $2.5 million stockholders’ equity requirement (and the alternative minimum requirement of $35 million in market value of its listed securities).

The transition to the OTC Market will not affect Sophiris’ business operations and the Company will remain subject to the public reporting requirements of the SEC following the transfer. The Company has been engaged in a discussion of strategic alternatives for more than a year and there is no assurance that Sophiris will be able to enter into any strategic transaction or be able to obtain additional financing to enable it to continue to operate.
