Honeywell International on Tuesday said it filed a Form 10 registration statement with the U.S. Securities and Exchange Commission for the planned spin-off of its aerospace business, Honeywell Aerospace, which will trade on the Nasdaq under the ticker HONA.

“Today’s Form 10 filing reflects the strong progress we are making toward the launch of Honeywell Aerospace as an industry-leading, independent aerospace and defense company,” Vimal Kapur, chairman and chief executive officer of Honeywell, said in a statement.

Honeywell Aerospace is expected to begin trading in the third quarter.

$17.4 billion aerospace business

According to the Form 10, Honeywell Aerospace generated pro forma 2025 net sales of $17.4 billion, pro forma net income of $1.5 billion and pro forma Adjusted EBIT of $4.3 billion.

The aerospace unit will operate three segments:

• Electronic Solutions, with $6.8 billion in 2025 net sales, focused on integrated avionics, navigation, sensors and space systems.
• Engines & Power Systems, with $5.4 billion in 2025 net sales, supplying propulsion systems, auxiliary power units and electric power technologies.
• Control Systems, with $5.2 billion in 2025 net sales, delivering thermal management and motion control systems used in flight, life support and safety applications.

Net sales were reduced by $312 million within the Engines & Power Systems segment due to Flexjet-related litigation matters disclosed in the fourth quarter of 2025.

The pro forma adjusted EBIT figure reflects $202 million in incremental costs tied to the separation, including expenses related to trademark licensing, transition services, executive compensation and pension service costs.

Positioned for electrification and defense growth

Jim Currier, president and chief executive officer of Honeywell Aerospace, said in a statement that the company is building momentum ahead of its public debut.

He added that the company’s “develop once, deploy everywhere” innovation strategy is designed to support both current and next-generation aerospace and defense platforms while expanding aftermarket opportunities.
