Merger ticker reuse and $8.13 ex-dividend mechanically create SUPN’s apparent 33% premarket drop

 

• Nasdaq reused SUPN for renamed Indivior effective November 3 after merger completion
• Legacy Supernus shares stopped trading; holders received 1.5401 combined-company shares each
• Nasdaq explicitly warned vendors not to carry legacy SUPN price history forward
• Indivior’s $8.13 special dividend went ex-dividend November 3, reducing its reference price
• Using Indivior’s $36.28 close, the dividend-adjusted reference is approximately $28.15
• The $28.17 premarket quote is essentially flat against that adjusted reference
• The displayed comparison incorrectly pairs new SUPN with legacy SUPN’s $41.92 close
• This is a corporate-action adjustment, not a genuine five-times-normal-range selloff
