Key Dates

Recommendation

The filing shows continued operational strength and progress on development projects, including securing a potential tenant for AI/HPC. However, the minor delay at the Briscoe Wind Farm and the ongoing nature of large-scale development projects suggest a 'hold' recommendation pending further financial results and de-risking of the development pipeline.
