Distribution Agreement regulatory
"offer and sale, from time to time, of up to 67,354,187 shares pursuant to that certain distribution agreement"
A distribution agreement is a contract that lets one party sell, market or deliver another party’s products or services in specified places or channels, and spells out who handles pricing, inventory, delivery, payments and how long the arrangement lasts. For investors it matters because these deals determine how widely a product can reach customers, how quickly revenue can grow, what profit margin the company keeps, and what legal or operational risks the business assumes—think of it like a store deciding which wholesaler will stock and promote a product.
Sales Agents financial
"Goldman Sachs and Morgan Stanley were added as Sales Agents under the Distribution Agreement"
Sales agents are individuals or firms that sell a company’s products or services on its behalf, often working on commission or under a sales agreement rather than as full-time employees. Investors care because agents affect how quickly and widely a product reaches customers, the cost of making sales, and revenue predictability—think of them as independent delivery drivers who expand a company’s reach without the fixed cost of hiring more staff.
Prospectus Supplement regulatory
"This Supplement should be read in conjunction with the Prospectus Supplement"
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.
Base Prospectus regulatory
"and the base prospectus dated July 28, 2025 (the “Base Prospectus”)"
A base prospectus is a detailed document that provides essential information about a financial offering, such as a bond or share issue. It acts like a comprehensive guide for investors, explaining what the investment involves, the risks involved, and how the process works. This helps investors make informed decisions before committing their money.
