It could all be part of the larger picture. A new cusip is required when a company takes a corporate action:
What instances require a change in the CUSIP number? A CUSIP number is assigned to each issue and may need to be changed when there is a Corporate Action. If there is a question as to whether an issuer needs to request a new CUSIP number, the company should contact the CUSIP Service Bureau directly at (212) 438-6565.
SVEN did do that reverse split back in September. Did they fail to get a new cusip then? Or were they perhaps planning another corporate action, one that hasn't been approved by FINRA?
Hard to say what's going on, but it does seem that the regulators are paying attention.
