Asset Purchase Agreement financial

"pursuant to the Asset Purchase Agreement, dated August 1, 2025, by and between the Registrant and SiVantage"

An asset purchase agreement is a legal contract in which a buyer agrees to buy specific assets and contracts of a business rather than buying the company’s stock or ownership. It matters to investors because it determines exactly what is being bought and what liabilities stay behind — like buying the furniture and equipment from a store but not the building or past debts — which affects the deal’s value, taxes and future risk exposure.

indirect pecuniary interest financial

"The securities reported herein represent the reporting person's indirect pecuniary interest in the shares held by SiVantage"

beneficial ownership financial

"The reporting person disclaims beneficial ownership except to the extent of his pecuniary interest"

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.
