This Report contains forward-looking statements, including statements of current intention and expectation. This includes statements regarding climate change and other environmental and energy transition scenarios. These forward-looking statements are based on information available at the date of this Report. While these forward-looking statements discuss Northern Star's expectations at the date of this Report, they are not guarantees or predictions of future performance, and by their nature, are subject to significant uncertainties, many of which are beyond Northern Star's control. Actual results and developments may differ materially from those expressed in this report and Northern Star cautions readers against reliance on any forward-looking statements or guidance. There are also limitations with respect to scenario analysis, and it is difficult to predict which, if any, of the scenarios might eventuate. Scenario analysis is not an indication of probable outcomes and relies on assumptions that may or may not prove to be correct or eventuate. Except as required by applicable laws or regulations, Northern Star does not undertake to publicly update or review any forward-looking statements, whether as a result of new information or future events.
