Private Placement Shares Purchase Agreement financial

"pursuant to the Private Placement Shares Purchase Agreement dated April 16, 2026"

over-allotment option financial

"subject to forfeiture depending on the extent to which the Issuer's underwriter' over-allotment option was exercised"

An over-allotment option is a special agreement that allows underwriters to sell more shares than initially planned if demand is high. Think of it like a retailer offering extra units of a popular product to meet additional customer interest. This option helps ensure the full sale is completed and can also give investors extra shares if they want more.

beneficial ownership financial

"Dr. Someit Sidhu disclaims any beneficial ownership of the securities held by JATT Ventures II L.P."

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.

pecuniary interest financial

"other than to the extent of any pecuniary interest he may have therein, directly or indirectly"
