Registration Statement on Form F-3 regulatory

"incorporated by reference into 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.

online media distribution technical

"to provide marketing and distribution services to communicate information about the Company, including through social media channels and online media distribution"

foreign private issuer regulatory

"REPORT OF FOREIGN PRIVATE ISSUER PURSUANT TO SECTION 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.
