Tender Offer financial

"to purchase all of the outstanding shares of Common Stock"

A tender offer is a proposal made by a person or company to buy shares from existing shareholders at a set price, usually higher than the current market value, within a specific time frame. It matters to investors because it can lead to a change in ownership or control of a company, and shareholders must decide whether to sell their shares at the offered price.

Offer to Purchase regulatory

"terms and subject to the conditions set forth in the Offer to Purchase"

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.

Volume-weighted average price (VWAP) market

"based on the volume-weighted average price per Diana share for the 30 days ended on June 16, 2026"

Volume-weighted average price (VWAP) is the average price of a security over a trading period where each trade’s price is weighted by how many shares were traded, so larger trades pull the average more than tiny ones. Investors and traders use VWAP as a benchmark to judge whether a trade was executed at a favorable price—similar to checking whether you paid more or less than the typical price when most people were buying or selling.

Schedule TO regulatory

"This Amendment amends and supplements the Tender Offer Statement on Schedule TO"

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.

Shareholder Rights Agreement legal

"including the associated preferred stock purchase rights issued pursuant to the Shareholder Rights Agreement"

A shareholder rights agreement is a legal contract that spells out the powers and protections of shareholders, such as how shares can be bought, sold, or diluted and what happens during takeovers or corporate disputes. It matters to investors because it shapes how much control they have, how their ownership can change, and what safeguards exist against abrupt changes—like a homeowner’s rules that prevent a single neighbor from altering the whole block.
