Sales Agreement regulatory

"entered into an amendment to the Sales Agreement to increase the amount"

A sales agreement is a written contract that sets out the terms for selling goods, services, or assets, specifying price, delivery, payment schedule and responsibilities of each side. For investors it matters because it creates a predictable stream of revenue or cash obligations, clarifies timing and risk, and can change a company’s value or forecasts much like a signed order turns a customer’s verbal intent into a firm commitment.

Sales Agent financial

"Roth Capital Partners, LLC (the “Sales Agent”)"

A sales agent is an individual or firm authorized to sell a company’s products or services on its behalf, typically paid by commission or fees rather than a fixed salary. For investors, who a company uses to reach customers and how well those agents perform affects revenue growth and profit margins — like hiring local independent sellers to expand into new neighborhoods without building stores — so agent quality and cost matter to future cash flow and valuation.

aggregate offering price financial

"shares of our common stock having an aggregate offering price of up to $49,326,334"

The aggregate offering price is the total dollar amount that will be raised if all the securities in an offering are sold at the stated offering price, before fees or expenses are taken out. Investors use it to gauge the size of the fundraising and its potential effects—such as how much cash the company will get and how much existing ownership might be reduced—similar to totaling every item’s price in a shopping cart to see the full bill.
