authorized share capital financial

"approved an increase in the Company’s authorized share capital from 30,000,000 ordinary shares"

The maximum number of shares a company is legally allowed to issue according to its governing documents. Think of it as the size of the blank checkbook a company keeps for selling ownership stakes: it sets an upper limit but does not mean all shares are in circulation. Investors care because a larger authorized amount makes it easier for the company to raise money or grant stock-based pay, which can dilute existing holdings and affect control and value per share.

ordinary shares financial

"from 30,000,000 ordinary shares, par value NIS 1.50 per share, to 500,000,000 ordinary shares"

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.

Registration Statement on Form F-3 regulatory

"ordinary shares registered for resale pursuant to the Company’s Registration Statement on Form F-3"

A registration statement on Form F-3 is a streamlined filing used by eligible foreign companies to register securities for sale in the U.S., often as a “shelf” that lets them offer shares quickly when market conditions are right. For investors it matters because it signals that the company can raise capital on short notice—potentially increasing liquidity but also the risk of share dilution if new stock is issued—similar to a company keeping a pre-approved credit line ready to use.

Memorandum and Articles of Association regulatory

"approved the corresponding amendment to the Company’s Amended and Restated Memorandum and Articles of Association"

Memorandum and articles of association are the founding legal documents of a company: the memorandum sets out the company’s basic purpose and scope, while the articles act as its internal rulebook detailing how the company is run, who has what powers, and how decisions are made. For investors these documents matter because they define ownership rights, voting rules, limits on activities, and procedures for major changes—like a contract and rulebook that determine how their investment can be used and protected.

opinion of counsel regulatory

"filing an updated opinion of Goldfarb Gross Seligman & Co., counsel to the Company"

foreign private issuer regulatory

"REPORT OF FOREIGN PRIVATE ISSUER PURSUANT TO RULE 13a-16 OR 15d-16"

A foreign private issuer is a company organized outside the United States that meets tests showing it is primarily foreign-controlled and therefore qualifies for a different set of U.S. reporting rules. For investors, that means the company files less frequent or differently formatted disclosures with U.S. regulators and may follow home-country accounting and governance practices, so buying its stock is like dining at a well-reviewed restaurant that follows its home kitchen’s rules instead of the local menu — you get access but should check what standards apply.
