Toronto Stock Exchange market

"it will be graduating to the Toronto Stock Exchange (the “TSX”)"

The Toronto Stock Exchange is Canada’s largest organized marketplace where shares of publicly traded companies are bought and sold, similar to a large, regulated marketplace for company ownership. It matters to investors because it provides transparent prices, rules that help protect buyers and sellers, and access to many Canadian and international businesses, so movements there can signal economic trends and affect portfolio values.

TSX Venture Exchange market

"Following the graduation from the TSX Venture Exchange (the “TSXV”) to the TSX"

A junior stock exchange in Canada where smaller, early-stage companies list shares to raise capital and gain public visibility. Think of it as a farmers’ market for young businesses: it offers investors a chance to buy into fast-growing but higher-risk ventures, with looser listing rules and typically lower liquidity than major exchanges. It matters because performance and financing on this exchange can signal growth prospects or risk for investors.

Nasdaq Capital Market market

"The Common Shares will continue to be listed on the Nasdaq Capital Market"

The Nasdaq Capital Market is a platform where smaller, emerging companies can list their shares for trading by investors. It provides these companies with access to funding and visibility, helping them grow, much like a local marketplace where new vendors can introduce their products to potential customers. For investors, it offers opportunities to discover early-stage companies with growth potential.

reporting issuer regulatory

"The Company will remain a reporting issuer under applicable Canadian securities laws"

A reporting issuer is a company or investment fund legally required to provide regular, public financial and corporate updates to securities regulators and investors. For investors it matters because those routine filings act like a business’s recurring health reports—offering consistent, official information to assess performance, risks and value so people can make informed buy, sell or compare decisions.

forward-looking statements regulatory

"This release includes certain statements and information that may constitute forward-looking statements"

Forward-looking statements are predictions or plans that companies share about what they expect to happen in the future, like estimating sales or profits. They matter because they help investors understand a company's outlook, but since they are based on guesses and assumptions, they can sometimes be wrong.
