beneficially owned financial

"Rows 11 and 13 of each Reporting Person's cover page ... 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.

Ordinary Shares financial

"Title of Class of Securities: 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.

working capital financial

"The source of the capital to purchase securities of the Issuer reported herein was Lynrock Fund's working capital"

Working capital is the money a business has available to cover its daily expenses, like paying bills and buying supplies. It’s like the cash in your wallet that helps you handle everyday costs; having enough ensures the business can operate smoothly without running into money shortages.

margin loans financial

"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.

investment management agreement financial

"pursuant to an investment management agreement, the Investment Manager has been delegated full voting and investment power"

An investment management agreement is a written contract that hires a professional to make buying, selling and strategy decisions for an investment account or fund, and sets out their duties, fees, risk limits, performance measures and reporting requirements. It matters to investors because the agreement determines who controls the money, how much the service costs, what risks are allowed, and how success or failure is measured—think of it as the service contract that defines expectations and remedies for a hired portfolio manager.

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.
