The organization over time
Each line starts at 100 in 2017, so what you read is the shape rather than the size: 150 means half as much again as 2017, 50 means half. The number beside each label in the key is where it ended. The shaded band is where the middle 50% of its peers' revenue would sit, given their growth.
How it's funded, over time
Each bar is one year's revenue split into where it came from, and every bar is the same height — these are shares, not amounts, so a year that raised twice as much looks the same size. Hover a bar for the split.
Government-grant reliance: 2021 16% · 2022 13%. Grants only. Government contracts and fees sit inside program revenue.
1% of TAMARISK INC’s revenue is contributions — about as donation-reliant as the typical peer (39% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 7 of the last 9 reported years ran a deficit.
