over-allotment option financial

"in connection with the expiration of the remaining portion of the underwriters' over-allotment option as described in the Registration Statement"

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.

Registration Statement regulatory

"as described in the Registration Statement"

A registration statement is a formal document that companies file with a government agency to offer new shares of stock to the public. It provides essential information about the company's finances, operations, and risks, helping investors make informed decisions. Think of it as a detailed product description that ensures transparency and trust before buying into a company.

beneficial ownership financial

"Dr. Someit Sidhu disclaims any beneficial ownership of the securities held by the Sponsor"

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"

ten percent owner regulatory

"JATT Ventures II L.P. is marked as a ten percent owner"
