beneficially owned financial

"Rows 11 and 13 of each Reporting Person's cover page to this set forth the aggregate number of Ordinary Shares and percentages of the Ordinary Shares beneficially owned"

Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

investment manager financial

"The Investment Manager is the investment manager of Lynrock Fund, and pursuant to an investment management agreement"

margin loans financial

"and which may, at any given time, include margin loans made by brokerage firms in the ordinary course of business"

Margin loans are loans from a brokerage that let an investor borrow money using their existing stocks, bonds or cash as collateral to buy more securities. They matter because borrowing magnifies both gains and losses—like using a lever to move a heavier load—so small market moves can have outsized effects on your returns; investors also pay interest and risk a margin call, where the broker may force sales if collateral falls below required levels.

open market financial

"All of such transactions were effected in the open market unless otherwise noted therein"

An open market is a system where buying and selling of goods, services, or financial assets happen freely without restrictions or special controls. For investors, it means they can trade assets easily and quickly, which helps determine fair prices based on supply and demand. This environment encourages transparency and competition, making it easier to buy or sell with confidence.

Ordinary Shares financial

"Ordinary Shares, NIS 0.20 par value per share"

Ordinary shares are a type of ownership stake in a company, giving shareholders a right to participate in the company’s profits and decision-making through voting. They are similar to owning a piece of a business, and their value can rise or fall based on the company's performance. Investors buy ordinary shares to potentially earn dividends and benefit from the company's growth over time.
