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.
