Key Terms

6 terms

beneficially own financial

"R01 Fund LP, R01 Capital LLC and R01 Capital Manager LLC beneficially own an aggregate of 22,152,695.00 shares"

Beneficially own means having the economic rights and risks of a security—such as the right to receive dividends, sell the shares, or profit from price changes—whether or not your name appears on the official share register. Think of it like renting a car: you use it and reap the benefits even if the title lists someone else. Investors care because beneficial ownership determines who truly controls value, must be disclosed under securities rules, and can signal potential influence or trading activity that affects a stock’s price.

pre-funded warrants financial

"pre-funded warrants issued by the Issuer to R01 Fund LP and other investors on October 16, 2025"

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.

anti-dilution adjustments financial

"to reflect anti-dilution adjustments under certain pre-funded warrants issued by the Issuer"

Anti-dilution adjustments are changes made to the ownership stakes or value of an investment to protect investors from having their shares become less valuable if the company issues new shares at a lower price. Imagine buying a piece of a pie, and then the pie is cut into more slices without increasing in size—these adjustments help ensure your slice still retains its worth. They matter to investors because they help preserve the value of their investment when the company’s share price drops.

Schedule 13D regulatory

"If the filing person has previously filed a statement on Schedule 13G to report the acquisition"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.

shared voting power financial

"Shared power to vote or direct vote: R01 Fund LP, R01 Capital LLC and R01 Capital Manager LLC: 22,152,695.00 shares"

Shared voting power occurs when two or more parties jointly have the right to vote or decide how a block of company shares is cast, like co-owners who must agree before moving a piece of furniture. Investors care because who controls voting rights affects board elections, major corporate decisions and takeover outcomes, and shared control can alter regulatory disclosures and the practical influence any holder has over a company’s direction and value.

dispositive power financial

"Sole power to dispose or direct the disposition: Michael Kazley: 4,118,828 shares of Common Stock"

Dispositive power is the authority to decide the final outcome of an asset, legal claim, contract, or corporate action — in effect the power to dispose of or resolve something. For investors it matters because whoever holds that authority can determine who gets paid, who controls an asset or vote, and how risks and returns are allocated; think of it like holding the key that lets you lock in the winner or loser in a deal.
