Global Ports Holding Ltd. (GPH), the cruise port operator and subsidiary of Global Yatırım Holding, completed the acquisition of an additional 10% indirect stake in Lisbon Cruise Port, Lda. on August 6, 2026. The parties had signed the purchase agreement on July 14, 2026. No purchase price was disclosed.

The acquired stake represents half of Royal Caribbean Cruises Ltd.'s 20% indirect interest in the port. Following the transfer, GPH's total indirect interest in Lisbon Cruise Port increased from 50% to 60%, while Royal Caribbean retains a 10% indirect interest.

Lisbon Cruise Port is the operator of the Lisbon cruise terminal under a concession agreement with the Port of Lisbon Authority. GPH has been the majority operator of the terminal since its initial investment. Royal Caribbean, one of the world's largest cruise lines and a significant customer of the Lisbon terminal, held a 20% stake prior to this transaction — a structure that aligned the interests of a major port user with the port's ownership.

The July 14 signing and August 6 closing reflect a relatively short period between execution and completion, suggesting that the required pre-conditions — which may have included port authority notifications, concession consent, and any applicable regulatory filings — were satisfied efficiently.

The increase from 50% to 60% is commercially significant, but its legal significance depends on the governance structure established in the shareholders' agreement governing Lisbon Cruise Port.

A 50% stake in a joint venture does not automatically confer control. In a 50/50 structure, both shareholders typically have equal governance rights, with major decisions requiring unanimous consent or supermajority approval. The 50% shareholder cannot unilaterally determine strategy, approve capital expenditures above a threshold, appoint management, or distribute dividends without the other shareholder's agreement.

A 60% stake, by contrast, may or may not confer unilateral control — depending entirely on the reserved matters and veto rights preserved for minority shareholders in the shareholders' agreement. If Royal Caribbean (now at 10%) and any other remaining shareholders retain veto rights over material decisions, GPH's effective governance authority at 60% may be only marginally greater than it was at 50%.

The key questions that must be answered by reviewing the shareholders' agreement are:

Board composition: How many board seats does each shareholder hold? Does GPH's 60% stake entitle it to appoint a majority of directors, or does the agreement preserve a more balanced composition?

Reserved matters: What decisions require unanimous consent or a supermajority? Typical reserved matters in port joint ventures include approval of the annual budget, capital expenditure above a threshold, entry into material contracts, changes to the concession agreement, and distributions.

Veto rights: Does Royal Caribbean retain any veto rights at 10%? In many infrastructure joint ventures, minority shareholders retain veto rights over specific matters regardless of their economic interest — particularly where the minority shareholder is also a significant commercial counterparty.

Drag and tag rights: Does GPH's increased stake trigger any drag-along rights that would allow it to force a sale of the remaining shares? Does Royal Caribbean retain tag-along rights that would allow it to participate in any future sale by GPH?

Lisbon Cruise Port operates under a concession agreement with the Port of Lisbon Authority (Administração do Porto de Lisboa). Concession agreements for port operations typically include change-of-control provisions that require the concessionaire to notify the grantor — and in some cases obtain the grantor's consent — before any change in the ownership or control of the concessionaire.

The fact that the transaction closed on August 6 suggests that any required notifications or consents were obtained prior to closing. However, the specific terms of the concession's change-of-control provisions are relevant to understanding:

• Whether the increase from 50% to 60% constituted a "change of control" under the concession's definition
• Whether the Port of Lisbon Authority was notified and, if so, whether it imposed any conditions on its consent
• Whether the concession agreement contains any restrictions on future ownership changes that may affect GPH's ability to further increase its stake or eventually sell the asset

For Turkish infrastructure investors — and for any investor considering a port concession acquisition — the concession change-of-control provisions are among the most consequential terms in the asset's legal framework. A concession that can be terminated or renegotiated upon a change of control creates significant transaction risk that must be addressed in the purchase agreement through representations, conditions to closing, and post-closing covenants.

One of the most legally and commercially interesting aspects of this transaction is the dual role that Royal Caribbean plays: it is simultaneously a shareholder in Lisbon Cruise Port and one of the port's most significant customers.

This dual role creates both alignment and tension. As a shareholder, Royal Caribbean benefits from the port's profitability and has an interest in its long-term development. As a customer, Royal Caribbean has an interest in competitive port fees, favorable berthing schedules, and service quality — interests that may not always align with maximizing the port's financial returns.

With Royal Caribbean's stake reduced from 20% to 10%, its governance influence over the port has diminished. The commercial question is whether this reduction in ownership will affect the terms of Royal Caribbean's port usage and berthing agreements. If Royal Caribbean's port usage contracts were negotiated at arm's length and are not linked to its ownership stake, the reduction should have no direct commercial impact. If, however, the port usage terms were influenced by Royal Caribbean's shareholder position — or if Royal Caribbean's continued investment was conditioned on favorable commercial terms — the ownership reduction may prompt a renegotiation of the commercial relationship.

GPH should ensure that its port usage agreements with Royal Caribbean are documented on arm's-length terms and are not subject to renegotiation triggers linked to ownership thresholds.

The GPH–Lisbon transaction illustrates several principles that are directly applicable to Turkish companies investing in international infrastructure assets.

Incremental stake acquisitions: GPH's approach — building from an initial position to 50% and then to 60% through incremental acquisitions — is a common strategy for infrastructure investors who want to increase their exposure to a performing asset without the execution risk of a full acquisition. Each incremental acquisition requires its own legal analysis of the governance implications, concession consent requirements, and financing structure.

Port concession due diligence: Turkish companies acquiring port, airport, or other infrastructure concessions internationally should conduct thorough due diligence on the concession agreement's change-of-control provisions, the grantor's consent rights, and the concession's remaining term and renewal conditions. These provisions can significantly affect the asset's value and the acquirer's ability to manage and eventually exit the investment.

Dual-role counterparties: Infrastructure assets frequently involve counterparties who are simultaneously customers, suppliers, and co-investors. Managing these relationships requires careful attention to governance documentation, arm's-length commercial terms, and conflict-of-interest procedures.
