Key Terms

Confirmatory Letter, beneficially owns, fully diluted basis, non-binding offer, +2 more

6 terms

Confirmatory Letter regulatory

"the Consortium jointly submitted a confirmatory letter (the "Confirmatory Letter")"

beneficially owns financial

"Cognisa Investment beneficially owns approximately 2.64% of the outstanding Shares"

Beneficially owns means a person or entity enjoys the economic benefits and control of a security even if the legal title or registration is held in another name. Think of it like having the keys and profits from a car that is registered to a friend: you use it, benefit from it, and make decisions about it even though the official paperwork lists someone else. For investors, this matters because it reveals who truly controls shares, affects voting power, potential conflicts of interest, and regulatory disclosure obligations.

fully diluted basis financial

"the Consortium is interested only in acquiring the Shares (on a fully diluted basis)"

A fully diluted basis counts every share that could exist if all outstanding options, warrants, convertible securities and other rights were exercised or converted into common stock, showing the maximum number of shares outstanding. For investors this matters because it spreads ownership and earnings across that larger share count, like slicing a pie into every possible piece before deciding how big each investor’s slice will be, which affects per-share value and ownership percentage.

non-binding offer financial

"to reaffirm the Cash Consideration of $7.02 per share as its best and final non-binding offer"

Class B Ordinary Share financial

"Mr. Sinha is the record holder of one Class B Ordinary Share"

A Class B ordinary share is a type of common stock that carries a specific set of rights—often different voting power or dividend priority—distinct from other share classes of the same company. Think of it like owning a different model of the same car: it gets you the ride (ownership and profit share) but may limit your say in steering (voting) or how quickly you receive payouts; investors care because these differences affect control, influence over management decisions, and potential return or liquidity.
