About STRONG FOUNDATION

The Strong Foundation (EIN 99-0090807) is a private foundation based in Honolulu, Hawaii, that has operated as a tax‑exempt private foundation for many decades. Its grantmaking is restricted to Hawaii 501(c)(3) charities, with an emphasis on capital projects and youth‑oriented initiatives; the trustees require a trustee sponsor for all applications, limit awards to one grant per organization every three years, and do not make multi‑year or endowment grants. The foundation files Form 990‑PF annually and has significant assets; in the fiscal year ending August 2022 the foundation reported approximately $1.41 million in revenue, $1.76 million in expenses (including charitable disbursements of roughly $1.51 million), and net assets in the low‑to‑mid $20 million range. Trustees named in the foundation's publicly posted grant guidelines include Anne Strong Carter (President) and other long‑serving trustees; Bank of Hawaii provides administrative/foundation services and hosts the foundation’s grant guidelines. In recent years the foundation has awarded capital and program grants to local Hawai‘i institutions—including significant support for higher‑education STEM facilities and youth health/resiliency programs—consistent with its stated priorities and capital‑project focus.
