The organization over time
Each line starts at 100 in 2021, so what you read is the shape rather than the size: 150 means half as much again as 2021, 50 means half. The number beside each label in the key is where it ended.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2024 to 2025, from $9.9M to $11M (+13%).
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 60% · 2022 40% · 2023 46% · 2024 46% · 2025 29%. Grants only. Government contracts and fees sit inside program revenue.
