Background

  • Paul Witmer, a stockholder of Aytu Biopharma, brought derivative claims against Armistice Capital, the company's largest investor, alleging overpayment in two transactions (acquisitions of Innovus and Cerecor portfolios) that allegedly benefited Armistice.
  • Armistice held a large but non-majority stake (around 41%) and had a board designee (Steven Boyd) on Aytu's board at the relevant times.
  • Witmer claimed Armistice improperly traded Aytu stock on material nonpublic information following these transactions, contrary to Aytu’s insider trading policy.
  • Other defendants (including directors and Boyd) were dismissed after a settlement in which Aytu took a position of neutrality as to claims against Armistice.
  • Armistice moved to dismiss all claims, disputing the sufficiency of Witmer’s pleadings regarding fiduciary duty, insider trading, aiding and abetting, and unjust enrichment.

Issues

Issue Plaintiff's Argument Defendant's Argument Held
Whether demand is excused since Aytu declared neutrality in settlement Demand is excused; Aytu’s neutrality counts as approval for derivative action Neutrality given in a settlement should not excuse demand; undermines board authority Demand is excused under existing Delaware law given board neutrality
Whether Armistice owed fiduciary duties as a controlling stockholder Armistice exerted transaction-specific control through large stake, board seat, process and disclosures Armistice lacked majority control and did not dominate board; lacked actual control No actual control or domination pled; Armistice is not a fiduciary
Whether Armistice owed fiduciary duties for insider trading based on access to MNPI through its board designee Access to confidential info via Boyd creates fiduciary duties for Armistice as an insider Fiduciary status does not arise by access through designee; only controlling stockholders have duties Mere access to MNPI via a designee does not create fiduciary duties for Armistice
Whether Armistice aided and abetted breaches of fiduciary duty or was unjustly enriched Armistice knowingly participated by withholding information, orchestrating transactions, and profiting No well-pled knowing participation or unjust enrichment separate from fiduciary duty claims No active substantial assistance or separate enrichment; claims dismissed
