The Blender Foundation has published their overview of 2019. Besides highlighting their milestones, the report also contains a financial overview. Note that this does not contain numbers on the Blender Institute's finances which include, for example, office rent.
A bit overdue, I know! Here is a report from Blender Foundation 2019. I am available to answer questions or reply to feedback in this thread. Just FYI: for 2020 we scheduled to make a more detailed report, include contributor profiles, realized projects and include the Blender Institute finances as well.
