Pre-Funded Warrants financial
"pre-funded warrants ("Pre-Funded Warrants") to purchase up to an aggregate of 30,978 shares"
Pre-funded warrants are financial instruments that give investors the right to purchase a company's stock at a set price, but with most or all of the purchase price paid upfront. They function like a coupon or gift card for stock, allowing investors to buy shares later at a fixed price, which can be beneficial if they want to avoid future price increases. This makes them important for investors seeking flexibility and certainty in their investment plans.
Common Warrants financial
"accompanying common warrants ("Common Warrants") to purchase up to an aggregate of 30,978 Shares"
A common warrant is a tradable instrument that gives its holder the right to buy a company’s common shares at a fixed price within a set time period, similar to a coupon that can be redeemed later to purchase stock. Investors care because exercising warrants can boost potential gains if the stock rises, but it can also dilute existing shareholders by increasing the number of shares outstanding, which can lower per-share value.
securities purchase agreement financial
"entered into a securities purchase agreement (the "Purchase Agreement") with certain accredited investors"
A securities purchase agreement is a written contract between a buyer and a seller outlining the terms for buying or selling financial assets such as stocks or bonds. It specifies details like the price, quantity, and conditions of the transaction, similar to a shopping list with agreed-upon terms. For investors, it provides clarity and legal protection when transferring ownership of these financial instruments.
accredited investors financial
"securities purchase agreement (the "Purchase Agreement") with certain accredited investors, including the Reporting Person"
Accredited investors are individuals or entities considered to have enough financial knowledge and resources to understand and handle more complex and risky investments. They are often allowed to participate in private investment opportunities that are not available to the general public, similar to how experienced players might access exclusive clubs or events. This status helps ensure that investors can manage potential risks and rewards appropriately.
Beneficial Ownership Limitation financial
"would exceed 9.99% of the combined voting power of all of the Issuer's securities outstanding immediately after giving effect to the exercise (the "Beneficial Ownership Limitation")"
A beneficial ownership limitation is a rule that caps the percentage of a company’s shares an investor can be treated as owning or controlling for voting, regulatory or tax purposes. It matters to investors because it can restrict how many shares a person or group can buy or vote, affect takeover chances, and influence share liquidity and value — like a speed limit that prevents any single driver from taking over the whole road.
private placement financial
"issued and sold to the Reporting Person in a private placement which closed on March 31, 2026"
A private placement is a way for companies to raise money by selling securities directly to a small group of investors instead of through a public offering. This process is often quicker and less regulated, making it similar to offering a special, exclusive investment opportunity to select individuals or institutions. For investors, it can provide access to unique investment options that are not available on public markets.
