5 terms

at-the-market equity program financial

"provided a quarterly update with respect to the Company’s previously announced “at-the-market” equity program"

An at-the-market equity program lets a company sell newly issued shares directly into the open market at the current trading price through a broker, rather than in a single, prearranged block. It provides flexible, on-demand access to cash—like drawing small amounts from a credit line—but increases the number of shares outstanding, which can reduce existing shareholders’ ownership percentage and put downward pressure on the stock price, so investors monitor program size and pacing.

Sales Agreement financial

"pursuant to a sales agreement (the “Sales Agreement”) between the Company, Canaccord Genuity and Evercore ISI"

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.

gross proceeds financial

"at an average price of US$3.59 under the ATM Program, providing gross proceeds of US$11,261,931"

The total amount of cash a company receives from a financing event or sale before any fees, expenses, taxes or deductions are taken out. Investors watch gross proceeds because it shows the raw scale of new capital being raised—think of it as the paycheck amount before withholdings—which helps assess how much funding is available for operations, growth, debt payoff or how much shareholder dilution might occur once costs are removed.

lithium-brine properties financial

"focused on the sustainable development of a portfolio of large, high-grade lithium-brine properties in the United States"

direct lithium extraction technical

"via the application of a scalable and fully integrated DLE and purification process"

A method for pulling lithium directly out of salty water or other raw sources using special materials and electrical or chemical processes, instead of relying on long evaporation ponds or mining rock. It matters to investors because it can speed up production, lower costs and environmental impact, and make lithium supply for batteries more reliable—like replacing a slow, weather-dependent harvest with a faster, machine-driven picker that boosts output and predictability.
