Bristow Group Inc.

We own and operate three categories of aircraft: rotary wing helicopters, fixed wing airplanes and UAS.

Our three classes of helicopters consist of:

•Heavy helicopters, which have twin engines, typical capacity of 16 to 19 passengers, and approximately 500-mile range, are primarily used in support of the deepwater offshore energy industry, frequently in harsh environments or in areas with long distances from shore, such as those in the U.S. Gulf of America, Brazil and the North Sea. Heavy helicopters are also used to support SAR operations.

•Medium helicopters, which have twin engines, typical capacity of 12 passengers, and approximately 450-mile range, are primarily used to support the offshore energy industry, SAR operations, utility services and corporate uses, among other missions.

•Light helicopters, which may have single or twin engines, typical capacity of four to seven passengers, and approximately 300 to 325-mile range, are used to support a wide range of activities, including the offshore energy industry, utility services and corporate uses, among other missions.

The management of our fleet involves a careful evaluation of the expected demand for helicopter services across global markets, segments, and the types of helicopters needed to meet this demand. Heavy and medium helicopters fly longer distances and can carry heavier payloads than light helicopters and are usually equipped with sophisticated avionics permitting them to operate in more demanding weather conditions and difficult climates. Heavy and medium helicopters are most commonly used for crew changes on large offshore production facilities and drilling rigs servicing the offshore energy industry and for SAR operations. See Part I, Item 2, “Properties” in this Annual Report on Form 10-K for discussion on our bases and operating facilities.

The table below presents the number of aircraft in our fleet as of December 31, 2025, their distribution among the segments through which we operate, as a percentage of total revenues for the year ended December 31, 2025, and the number of aircraft not yet reflected in our fleet as they were on order or under construction as of December 31, 2025.

(1)Under construction reflects new aircraft that the Company has either taken possession of and are undergoing additional configuration before being placed into service or are currently under construction by the Original Equipment Manufacturer (“OEM”) and pending delivery. Includes seven AW189 heavy helicopters (of which one was delivered and is undergoing additional configuration) and two AW139 medium helicopters (both of which were delivered and are undergoing additional configuration).

(2)Options include ten AW189 heavy helicopters and nine H135 light-twin helicopters.

(3)Excludes any orders or options for electric/hybrid vertical takeoff and landing and short takeoff and landing aircraft, collectively known as Advanced Air Mobility (“AAM”) aircraft that may have deposits but are pending regulatory certification.

The following table identifies the types of aircraft that comprise our fleet and the number of those aircraft in our fleet as of December 31, 2025.

(1)Does not include certain aircraft shown in the under construction line in the fleet table. Upon completion of additional configuration, the newly-delivered aircraft will appear in the fleet table above when placed into service.

(2)Reflects the average age of helicopters that are owned by the Company.

Air Operator Certificates

Globally, we provide and operate aircraft under contracts using an Air Operator Certificate (“AOC”), typically issued by the relevant country’s applicable regulatory agency. In certain markets, local regulations may require us to partner with another operator, through an alliance or joint venture, who maintains an AOC compliant with the local regulatory requirements. For operating contracts, we are required to provide a complete support package including flight crews, helicopter maintenance and management of flight operations. When we lease helicopters to other operators, our customers generally handle the operational support, although in a few instances we do provide technical support, personnel and/or training services.

Currently, we have aircraft in 15 different countries, on five different continents under 12 AOCs.
