Stonepeak Brand Guidelines: A 2011 Blackstone Spin-Out, ATSG, United Ports & Castrol

Two Macquarie bankers, a Blackstone unit and a 2011 spin-out.

Stonepeak is a New York investment firm that puts money into infrastructure and real assets. Its roots lie in 2008, when Michael Dorrell and Trent Vichie moved from the Australian group Macquarie to Blackstone to set up an infrastructure investment unit there, English Wikipedia says. In 2011 that unit was spun off as an independent firm, Stonepeak, based in New York. The two are named as its co-founders; Vichie left in March 2021 to found his own company, EverWind Fuels, according to the same source.

The firm is also known as Stonepeak Partners and Stonepeak Infrastructure Partners. English Wikipedia lists offices in Hong Kong, Houston, London, Sydney and Singapore alongside New York, and notes that several of its senior managing directors, like both co-founders, previously worked at Macquarie. Its first fund, Stonepeak Infrastructure Fund I, drew money from US public pension plans including those of Washington State and Oregon, and from the retirement-fund provider TIAA.

Stonepeak describes its job in plain terms. It says it invests “in the infrastructure that underpins our daily lives” — the physical assets that “power homes, connect communities to the internet, feed families, enable travel, and deliver goods” — on behalf of more than 350 investors, including pension funds and endowments. In July 2022 it launched its first real estate fund, and in July 2023 the asset manager Blue Owl Capital took a minority stake in the firm itself, English Wikipedia says. In August 2025 it launched WahajPeak, a renewable-energy platform for solar, wind and battery storage projects in the Gulf states and the wider Middle East.

Fibre, containers, freighters and ports.

Stonepeak’s record reads as a list of businesses that move data, goods and energy. English Wikipedia dates its purchase of the data-centre operator Cologix to March 2017 and of the cable and fibre provider Astound Broadband, bought from TPG, to November 2020. In October 2021 it bought Teekay LNG, a gas-shipping company; in November 2022 it and the Australian pension fund Spirit Super bought the Port of Geelong in Victoria; and in March 2024 it completed the take-private of Textainer, a Bermuda-based lessor of intermodal shipping containers.

Air cargo followed. Stonepeak’s purchase of Air Transport Services Group (ATSG), the Ohio-based lessor of midsize widebody freighter aircraft, was announced on 4 November 2024, approved by ATSG’s stockholders on 10 February 2025 and completed on 11 April 2025, according to the release ATSG issued that day from Wilmington, Ohio; its shares then stopped trading on Nasdaq. English Wikipedia notes that ATSG’s airlines include ABX Air and Air Transport International.

In Europe, Stonepeak and Energy Equation Partners agreed in May 2025 to buy a majority interest in the German and Austrian retail fuel business of Phillips 66, operator of the JET service-station network; English Wikipedia says that deal closed on 1 December 2025. In January 2026 Stonepeak agreed with the French shipping group CMA CGM to form United Ports, a US port venture. The two companies announced its completion on 28 July 2026, after regulatory approvals, with Stonepeak holding 25% and CMA CGM keeping 75% and full operational control.

Not every deal has closed. On 11 March 2026 Alphabet and Stonepeak agreed to combine Google Fiber (GFiber) with Astound, with Stonepeak as majority owner and Alphabet keeping a significant minority stake, English Wikipedia says; that deal was agreed in March 2026 and was expected to close in the fourth quarter of 2026, and it was not completed at the time of writing.

Infrastructure investors.

Infrastructure investors sell something hard to picture: long-term ownership of things other people use every day. Their websites therefore lean on the assets themselves. Macquarie Asset Management’s pages open on named portfolio companies, from a New Zealand telecoms provider to an onshore wind farm in north-eastern Brazil, and Brookfield Infrastructure sorts its portfolio into utilities, transport, midstream and data, with ports, railways, toll roads and pipelines named as the things it owns and runs.

The language is consistent too. Brookfield Infrastructure speaks of “critical infrastructure” and long-life assets with contracted and regulated revenues; Macquarie Asset Management says it seeks results “over the long term.” Responsible-investment wording sits alongside it: Macquarie’s purchase of the former UK Green Investment Bank in 2017, renamed Green Investment Group, came with a green “special share” held by independent trustees, according to the UK government’s announcement of the sale.

Listed vehicles add another layer of documents. Brookfield Infrastructure publishes quarterly results, supplemental information, letters to unitholders and investor-day presentations, and in 2026 it set out a plan to fold its two listed securities into one. Parent groups publish annual reports and history timelines; Macquarie’s runs from a three-person Sydney office in 1969 to the motorway deal of 1994 that it calls the start of its infrastructure business.

Trade rankings are part of the picture. Infrastructure Investor’s II 100 list of managers placed GIP, by then part of BlackRock, at the top in November 2024, and noted that Macquarie, first in every earlier edition, had dropped to fourth. This guide sets out what can be checked about each firm — who founded it, who owns it and how it presents its portfolio — and marks clearly what rests only on the company’s own word.

Castrol, and a website about assets.

The deal that brought Stonepeak to a wider audience was Castrol. BP agreed at the end of 2025 to sell a 65% stake in its lubricants business to Stonepeak, keeping 35% for itself. The sale completed on 2 November 2026: BP announced the completion that day, Transport Topics reported, and Stonepeak’s own release, dated London and New York, said a new Castrol board had been appointed at closing. The release adds that Canada Pension Plan Investment Board (CPP Investments) supports the transaction as an indirect minority holder, and it calls the closing a milestone in Castrol’s 127-year history. A British lubricants brand is now majority-owned by a New York infrastructure investor.

Stonepeak’s own website is written in the language of the assets it buys. Its home page groups its holdings under captions about solar energy, connectivity across North America, the food supply chain and “the backbone of the global supply chain,” and its about page speaks of assets that power homes, secure jobs and feed families. The palette and type in this guide are our own interpretation of that plain, engineering-minded register.

For a design guide, Stonepeak shows a firm whose public story is told through the ports, fibre and fleets it owns rather than through finance. Compare KKR, another New York private-markets firm with an infrastructure business, and BlackRock, another New York investment firm with a live guide here. For this guide we use slate, a harbour blue, granite grey and a quarry stone with a sans, an unofficial interpretation; no product or logo is reproduced.
