"This statement is filed by Highbridge Capital Management, LLC...with respect to the common stock...issuable upon exercise of warrants"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

Securities Exchange Act of 1934 Section 13 regulatory

"should not be construed as an admission that any of the foregoing persons...is the beneficial owner"
