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.
Balance sheet
Total assets and total liabilities at each year end, in dollars. The largest one-year move in total assets was 2017 to 2018, from $483M to $410M (−15%).
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.

Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 3 funders, grant income rose $13k → $4.3M.
2 of 8 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 0% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
Left out of every figure on this page: $33M from one payer (the payer shares this organization's board, largest Mercy Health Foundation South). These are real filings, and they are not money MERCY HOSPITAL SOUTH raised.

How concentrated its funding is
MERCY HOSPITAL SOUTH leans on a few funders — its largest provides 99% of grant income and the top three 100%; half comes from just 1 funder.

“Effective funders” = inverse Herfindahl index (1 / Σ shareᵢ²) — the number of equal-sized funders that would give the same concentration. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
How long its funders stay
40% of MERCY HOSPITAL SOUTH's funders are still giving 3 years after their first grant; 50% give in more than one year at all.
Share of funders still giving k years after their first recorded grant, pooled across every acquisition cohort. A funder counts as retained in a year only if it made a grant that year. Measured to FY2023, the last fiscal year that has finished arriving — a funder cannot be counted as lapsed in a year most filers have not reached.
Where its funders are
99% of MERCY HOSPITAL SOUTH's grant income comes from Missouri funders.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $18k arriving through sponsors registered in 2 states is excluded from the map and the split above: a sponsor holds money on a donor’s behalf, so its registered address would place those dollars somewhere no donor need ever have been. Trends are read to FY2023, the last fiscal year that has finished arriving. FY2024–FY2026 are still being filed and are shown unshaded; they do not move any figure on this page.
