Golub Capital Private Income Fund I 8-K

What Happened
Golub Capital Private Income Fund I (the “Company”) filed an 8-K on June 29, 2026 disclosing that its wholly owned subsidiary GPIF I Funding entered into a second amended and restated side letter to the revolving credit and security agreement (the “BANA Credit Facility”) dated June 23, 2026. The Side Letter changes the minimum utilization level used to calculate the unused commitment fee through September 30, 2026.

Why It Matters
This amendment affects how the unused commitment fee on the Company’s revolving credit facility is calculated, which can influence short‑term borrowing costs and the cost of maintaining unused lending capacity. The change is time‑limited (through Sept. 30, 2026) and does not, by itself, disclose changes to the Company’s financial statements or capital structure beyond the fee calculation—investors should review the attached Side Letter for full terms.
