Preferred Stock financial

"Series B Preferred Stock, Series B-1 Preferred Stock and Series C Preferred Stock"

Preferred stock is a type of ownership in a company that typically offers investors higher and more consistent dividend payments than common stock. Unlike regular shares, preferred stock usually doesn’t come with voting rights but provides a priority claim on the company’s assets and profits, making it a more stable and predictable investment option. This makes preferred stock attractive to those seeking steady income with lower risk.

pecuniary interest regulatory

"in which the Reporting Person has no pecuniary interest"

beneficial ownership regulatory

"disclaims beneficial ownership within the meaning of Section 16"

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.
