Stated investment criteria
What Quinbrook Infrastructure Partners says it buys
Read from Quinbrook Infrastructure Partners’s own website in August 2026. This is what the firm says it buys, not what anyone has recorded it buying, and figures are shown in the currency the firm itself used - nothing here is converted. Every line links to the page it was read from.
A stated mandate is a firm’s description of itself and was true of the page on the day it was read; firms widen and narrow what they will look at without updating the site. The team figure counts the people the firm shows on one team page, so it is a floor rather than a headcount: firms that split their team across tabs or load it in pages will read low. Nothing here is a commitment by Quinbrook Infrastructure Partners to consider any particular business, and nothing on this page is represented as being for sale.
SEC filings
What Quinbrook Infrastructure Partners has raised
From this firm's own Form D filings. A fund files one within fifteen days of its first sale, under penalty of perjury, which makes these the hardest numbers on the page.
| Vehicles filed | 3 |
| Total capital raised | $4.8bn |
| Largest single vehicle | $1.6bn |
| Filing history | 2021 |
| Smallest accepted commitment | None stated |
| Filed from | JERSEY |
Form D covers US-domiciled vehicles raised from accredited investors. It will not capture a fund raised outside the United States, separately managed accounts, or capital deployed off balance sheet, so treat these as a floor rather than a total.
