5 terms

volume weighted average price financial

"10% premium to the five-day volume weighted average price"

The volume weighted average price (VWAP) is a way to measure the average price of a security, such as a stock, over a specific period, taking into account how many units were traded at each price. It’s similar to calculating the average cost of items bought when some are more frequently purchased than others. Investors use VWAP to assess whether a security is being bought or sold at a fair price during trading.

Voting Support Agreement financial

"Urion has agreed to vote its Common Shares"

A voting support agreement is a written promise by major shareholders or stakeholders to vote their shares a specific way on a planned corporate action, such as a merger or management slate. It matters to investors because it increases the likelihood that the action will pass — like a group of neighbors agreeing in advance to back a local project — which reduces deal uncertainty but can also concentrate control and limit minority influence.

standstill financial

"customary standstill and lock-up provisions"

A standstill is a temporary agreement in which one party agrees to pause certain actions — such as buying more shares, launching a takeover bid, or enforcing debt claims — for a set period. For investors this matters because it freezes changes in ownership or legal pressure, giving markets time to absorb information and reducing short-term volatility; think of it as pressing a pause button so everyone can negotiate or reassess without sudden moves.

hold period regulatory

"subject to a hold period expiring four months and one day"

A hold period is a specific span of time during which an investor is required or expected to keep a security or asset and cannot freely sell it or realize its value. It matters because it limits liquidity and can affect tax treatment, risk exposure and timing of gains or losses—like a cooling-off or fixed-term commitment that prevents you from quickly cashing out even if market conditions change.

non-diluted basis financial

"approximately 3.0% on a non-diluted basis"

Non-diluted basis describes ownership percentages or per-share figures calculated using only the company’s currently outstanding shares, ignoring any potential future shares from options, warrants, convertibles or planned issuances. Investors use it to see the present snapshot of claims or earnings per share as if the pie’s size won’t change; it’s like measuring each person’s slice today without accounting for guests who might later get slices.
