Schedule TO regulatory
"This Amendment amends and supplements the Tender Offer Statement on Schedule TO filed"
A phrase indicating that a company plans or intends to hold an event, publish information, or take an action at a specified future time, but that the timing is not guaranteed and may change. For investors it signals an expected milestone—like an earnings call, product launch, or filing—so think of it as a calendar note rather than a firm promise; timing shifts can affect trading, expectations, and planning.
Offer to Purchase financial
"upon the terms and subject to the conditions set forth in the Offer to Purchase, dated May 4, 2026"
An offer to purchase is a formal proposal from one party to buy a specific amount of shares or assets from another party at a set price. It matters to investors because it signals interest in acquiring ownership and can influence the value or control of a company. Think of it as someone putting forward a clear, serious offer to buy something they find valuable.
Beneficially owned regulatory
"Diana beneficially owns, as of May 18, 2026, 6,304,548 Common Shares"
Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.
