Prospectus supplement regulatory

"This prospectus supplement updates, amends, and supplements the prospectus"

A prospectus supplement is an additional document provided alongside a company's main offering details, offering updated or extra information about a specific financial product being sold. It helps investors understand the latest terms, risks, and details of the investment, similar to how an update or revision clarifies or expands on original instructions, ensuring they have current and complete information before making a decision.

Report of Foreign Private Issuer regulatory

"Form 6-K Report of Foreign Private Issuer Pursuant to Rule 13a-16"

A report of a foreign private issuer is a formal filing that a non‑U.S. company makes to U.S. regulators to share important business, financial, or governance information with American investors. Think of it as a regular update or press packet that keeps investors informed about events that could change a company’s value—like earnings, management changes, contracts, or regulatory developments—so investors can make timely, informed decisions.

Form 6-K regulatory

"information contained in our Report of Foreign Private Issuer on Form 6-K"

A Form 6-K is a report that companies listed in certain countries file to provide important updates, such as financial results, corporate changes, or other significant information, to regulators and investors. It functions like an official company update or news release, helping investors stay informed about developments that could affect their investment decisions.

Inline XBRL technical

"Inline XBRL Instance Document"

Inline XBRL is a file format for financial filings that embeds machine-readable data tags directly inside the human-readable report, so the same document can be read by people and parsed by software. For investors it makes extracting, comparing and verifying financial numbers faster and more reliable—like a grocery list where each item also has a barcode—reducing manual errors and speeding up analysis.

Form F-3 regulatory

"incorporated by reference into the Company’s Registration Statements on Form F-3"

Form F-3 is a U.S. securities filing that lets eligible foreign companies pre-register and then quickly sell shares or other securities to raise money, because they already meet ongoing reporting and size tests. For investors it signals that the company is up-to-date with regulatory disclosure and has an efficient way to issue new securities — similar to a pre-approved credit line — which can mean faster capital raises but also potential dilution of existing holdings.

Form S-8 regulatory

"Registration Statements on Form S-8"

A Form S-8 is a U.S. Securities and Exchange Commission registration that lets a public company set aside shares for employee benefit plans and stock-based compensation. Think of it as opening a dedicated account that authorizes the company to issue or reserve stock for workers and directors; it matters to investors because it enables share dilution when those awards are granted or exercised and signals how management is compensated and incentivized.
