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.
0% of Riddle Memorial Hospital’s revenue is contributions — about as donation-reliant as the typical peer (1% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 4 of the last 9 reported years ran a deficit.

Who funds it, year by year
2017 → 2023: the base broadened from 2 funders to 3 funders, grant income rose $20k → $106k.
3 of 5 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 69% 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: $20M from one payer (the payer shares this organization's board, largest The Riddle Healthcare Foundation). These are real filings, and they are not money Riddle Memorial Hospital raised.
From the IRS filings of Riddle Memorial Hospital’s funders (the co-funder graph). Association, not causation. 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 concentrated its funding is
Riddle Memorial Hospital leans on a few funders — its largest provides 55% of grant income and the top three 97%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
69% of the income these shares are computed over arrives through pass-through sponsors or from payers whose filings do not say what kind of payment it is. Concentration is still measured over all of it, because the money is real; what it does not support is a claim about how many institutions have chosen to fund Riddle Memorial Hospital.
Largest funder’s share by year: 2017 87% · 2018 91% · 2019 100% · 2020 100% · 2022 100% · 2023 47% — diversifying over time.
“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.
Where its funders are
69% of Riddle Memorial Hospital's grant income arrives through donor-advised or pass-through sponsors, whose addresses record where the money is held rather than where the donor is. Of the $130k that is directly attributable, 96% of it comes from funders outside Pennsylvania, across 2 states.
In-state vs out-of-state, by year
Funder states come from each funder’s own filing. $284k arriving through sponsors registered in 2 statesis 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.
