Aircastle Brand Guidelines: A 2004 Stamford Lessor, an NYSE Listing & Japanese Owners

A young lessor with three offices.

Aircastle is an aircraft lessor: it buys commercial jets, leases them to airlines and sells them on. English Wikipedia gives its incorporation date as 29 October 2004, and Forbes, previewing its share offering in August 2006, dated the company’s first reporting period from the same day. Aircastle says it acquired its first aircraft in 2004, and its sustainability page says its values “anchored our founding in 2004.” Its head office is in Stamford, Connecticut, with offices in Dublin and Singapore — the same three regions Forbes described in 2006, when it listed offices in the United States, Ireland and Singapore.

The early fleet was small. Forbes reported that on 31 March 2006 Aircastle had 42 planes leased to 24 airlines in 16 countries, a mix of Boeing 737s, 757s and 767-300ERs and several Airbus types, with an average age of 8.7 years. Its four largest customers at the time, the magazine said, were US Airways, Hainan Airlines, Swiss International and Air India. Forbes also noted the company’s short operating history and named its major competitors, among them AerCap and Aviation Capital Group.

Aircastle listed on the New York Stock Exchange under the ticker AYR in August 2006, with J.P. Morgan, Bear Stearns and Citigroup leading the offering, according to Forbes. English Wikipedia says the shares traded from August 2006 until March 2020, when the company became privately owned. For most of its life, then, Aircastle has presented itself as a listed company and, later, as a privately held one that still publishes detailed results.

Narrow-bodies, mid-life jets and engines.

The company’s fact sheet describes its focus as “secondary market aircraft leasing.” As of 31 August 2026, Aircastle says, it owned and managed 268 aircraft leased to 67 customers in 42 countries. English Wikipedia gives an earlier snapshot: 277 aircraft with 87 lessees in 48 countries at the end of September 2019.

Its aircraft page describes a predominantly narrow-body fleet. Four newer types lead the page — the Boeing 737-8 MAX, the Airbus A320neo and A321neo and the Embraer E195-E2 — followed by earlier Airbus, Boeing and Embraer models, A330 wide-bodies and a converted 737-800 freighter. The sustainability page says the majority of its new acquisitions are fuel-efficient, newer-technology aircraft.

That shift is documented outside the company. Aviation Week reported in January 2026 that in Aircastle’s third financial quarter, the three months to 30 November 2025, new-technology aircraft passed half of its portfolio by value for the first time. The same report quoted the chief executive saying that lease extensions “far outnumber” transitions, and the finance chief describing how the company balances engine use across its fleet as airlines keep older aircraft in service for longer.

The customers page is a wall of airline logos, “from flagship airlines to low cost carriers,” including KLM, British Airways, easyJet and IndiGo. The company also publishes annual ESG reports, from 2021 to 2025 on its website, and lists itself as a gold-level sponsor of Airlink.

How lessors present themselves.

Aircraft lessors sell nothing to the travelling public. They buy commercial jets, lease them to airlines and sell them on, so their identities are built for airlines, lenders and investors rather than passengers. Their websites tend to open with a short line of figures — aircraft owned and managed, airline customers, countries — dated to the end of a reporting quarter, as Aircastle and Aviation Capital Group both do.

The aircraft themselves carry other companies’ colours. A lessor’s jet flies in its customer’s livery, so the photographs on lessors’ sites and in their press releases show airlines’ paint schemes rather than the lessor’s own. Aviation Capital Group announced in September 2026, for example, that it had delivered the first Boeing 737-8 in Trinity Airways’ new identity. Fleet pages list aircraft by type, and order-book pages count commitments from the manufacturers years ahead.

Customer pages are often walls of airline logos, sometimes grouped by region, and services pages explain the business in plain terms: operating leases, sale-and-leaseback deals in which a lessor buys an airline’s new aircraft and leases it back, trading in mid-life aircraft, and managing aircraft for other owners. Engines are a business of their own; trade reports describe lessors balancing engine use across their fleets, and some groups plan to expand into engine leasing.

Many of these companies are owned by banks, trading houses or investment firms, and their investor pages — results, fact sheets, credit ratings and bond reports — carry as much weight as the leasing pages. For the guides in this group we use navy, teal and silver tones with sans and serif stand-ins, an unofficial interpretation chosen for a finance-led sector; no company’s logo, livery or photograph is reproduced.

Marubeni, Mizuho Leasing and a quieter way to report.

Ownership changed in 2019 and 2020. English Wikipedia says that on 6 November 2019 Aircastle agreed to merge with Marubeni and Mizuho Leasing, and that Marubeni had already been its largest shareholder; the deal was completed on 27 March 2020. Aircastle’s own November 2026 announcement gives the same completion date and says the company became privately held at that point. Its fact sheet calls the ownership structure with Marubeni and Mizuho Leasing a competitive strength that gives it access to Asian financing sources.

The leadership has been stable. Aircastle says Michael Inglese served as chief financial officer from April 2007, became chief executive in June 2017 and joined the board on 27 March 2020, the day of the acquisition by affiliates of Marubeni and Mizuho Leasing.

Being private did not end its public reporting at first. On 4 November 2026 Aircastle announced that it intends to stop filing voluntary reports with the U.S. Securities and Exchange Commission. It said it had kept filing partly to meet the terms of certain bonds; the last of those bonds were repaid on 13 May 2026, and its quarterly report for the period to 31 August 2026 is expected to be the final one. The company said it intends to file a Form 15 with the SEC on or about 18 November 2026, and to keep publishing quarterly unaudited and annual audited statements in the investor section of its website.

The website itself is restrained: a fact sheet, a figures panel with aircraft, lessees and countries, aircraft pages with photographs of each type, and a news list of results and financings. Its code loads Google’s Noto Sans and Noto Serif typefaces.

For a design guide, Aircastle shows how a lessor with no consumer product builds its identity from numbers, aircraft types and airline names. Compare SMBC Aviation Capital, another lessor with Japanese owners, and AerCap, which Forbes named among its competitors in 2006. For this guide we use navy, slate and silver with a sans, an unofficial interpretation; no product or logo is reproduced.
