5 terms

non-dilutive open market purchases financial

"completed its acquisition of 1.2 million common shares...through non-dilutive open market purchases"

investor rights agreement financial

"conditions for the extension of the amended and restated investor rights agreement"

A legally binding contract between a company and its investors that spells out investors’ core protections and privileges—such as voting rights, how and when shares can be sold, information access, and steps for resolving disputes. Think of it like a rulebook or homeowner association agreement for ownership: it clarifies who gets a say, how value can be realized, and what protections exist if things go wrong, making investment risks and expectations clearer for shareholders.

Yukon Environmental and Socio-economic Assessment Board regulatory

"requests received from the Executive Committee of the Yukon Environmental and Socio-economic Assessment Board"

terms of reference regulatory

"the Executive Committee will establish the Panel and set its terms of reference"

A terms of reference document is a concise rulebook that sets the purpose, scope, responsibilities, authority and expected deliverables for a committee, review, investigation or project. It matters to investors because it clarifies what will be examined, who will decide, how independent and thorough the process will be, and the likely timeline—factors that shape the credibility of outcomes and potential impacts on a company’s risk and value.

National Electricity Strategy regulatory

"builds on Canada's National Electricity Strategy, launched by Prime Minister Mark Carney"
