Navigator Gas Announces Signing of Definitive Agreements to Sell Eight

Gas Carriers and Its Shareholding in Unigas Joint Venture

LONDON, July 14, 2026 – Navigator Holdings Ltd. (described herein as “Navigator Gas” or the “Company”) (NYSE: NVGS), the owner and operator of the world’s largest fleet of handysize liquefied gas carriers, announces, following the execution of a non-binding letter of intent previously announced on April 15, 2026, that yesterday, July 13, 2026, it signed definitive agreements to sell eight gas carriers (the “Vessels”), as well as its shareholding in the Unigas International B.V. joint venture (the “Unigas Pool”), for an aggregate purchase price of approximately $183 million (the “Transaction”).

The eight Vessels to be sold as part of the Transaction are summarised in the table below:

Vessel		Capacity (m3)			Year Built
Happy Pelican			6,800			2012
Happy Penguin			6,800			2013

The Vessels and shares in the Unigas Pool are to be sold to Bernhard Schulte Investment Holding GmbH and Sloman Neptun Schiffahrts-Aktiengesellschaft, the existing partners in the Unigas Pool. The proceeds from the Transaction are expected to be used for general corporate purposes.

As previously announced, the Transaction is consistent with the Company’s ongoing focus on fleet optimization and disciplined capital allocation, and will allow it to focus on its long-term fleet strategy centred on growing and consolidating handysize and midsize ethylene-capable vessels.

The Transaction, which is subject to customary closing conditions, as well as delivery of the Vessels pursuant to it, is expected to be completed by the fourth quarter of 2026, after which the Company’s fleet will consist of 46 vessels, 16 of which will be ethylene and ethane capable.
