What Ias does
Mission
To provide critical platforms for presenting new research, sharing best practices and advancing the fight against aids and promoting dialogue, education and networking to help close gaps in knowledge and expertise at every level of the response to aids.
As stated on its FY2025 Form 990.
Program
Ias 2025, the 13th international aids society conference on hiv science, took place in kigali, rwanda, and virtually from 13 to 17 july 2025. Despite challenges created by sudden funding cuts, almost 4,000 people came together in kigali and virtually, showing the resilience that defines the hiv response and a commitment to protecting gains made in over 40 years of this pandemic. Ias 2025 provided a forum for participants to review the early impact of us funding cuts and debate how the hiv response can adapt to shrinking donor support. Scientific innovation in prevention was also at the forefront during Ias 2025, with the release of new world health organization (who) guidelines recommending the use of long-acting injectable lenacapavir as a pre-exposure prophylaxis (prep) option and the presentation of promising data on the experimental monthly prep agent, mk-8527. Ias 2025 showcased the central role of african science in shaping the global hiv response. The conference also highlighted the host country's achievement in reaching the 95-95-95 targets for hiv diagnosis, treatment and viral suppression and its success in tackling a marburg virus outbreak in 2024.

The program described on its FY2025 Form 990. Program spending in total: $940,000.
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 2019 to 2020, from $5.9M to $12M (+105%).
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: 2017 85% · 2018 64% · 2019 70% · 2020 77% · 2021 86% · 2022 67% · 2023 57% · 2024 82% · 2025 76%. Grants only. Government contracts and fees sit inside program revenue.
79% of IAS’s revenue is contributions — more donation-reliant than the typical peer (51% for the typical peer).
Surplus & reserves
Operating surplus or deficit each year, and months of liquidity in hand. 2 of the last 9 reported years ran a deficit.

Leadership and staff
The officers, directors, trustees and key employees listed on each return. Joined and no longer listed compare each filing with the year before, matching people by surname and first initial; a year after a gap, or a roster under three people, has no comparison.

Who funds it, year by year
2020 → 2022: the base held at 1 funder, grant income fell $50k → $10k.
2 of 2 of your funders are donor-advised or pass-through sponsors (tagged DAF) — 100% of grant dollars received. That money is really individual donors directing a sponsor; the institutions to cultivate are the non-DAF funders.
From the IRS filings of IAS’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
IAS leans on a few funders — its largest provides 83% of grant income and the top three 100%; half comes from just 1 funder.
the vertical line marks half of all grant income — 1 funder to its left
100% 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 IAS.
Largest funder’s share by year: 2020 100% · 2022 100% — broadly stable.
“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
100% of IAS'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. Too little is directly attributable to place on a map.
Funder states come from each funder’s own filing. $60k 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.
Against its field
IAS runs a healthier operating margin than three-quarters of the 4,665 health nonprofits its size.
