ESA geographical return: why US space companies buy in Europe

In 2026, ESA geographical return still shapes where European Space Agency contracts go. The rule steers work to industry in the countries that fund each programme, in line with their contributions. As a result, a company based only in the United States rarely wins ESA contracts directly. Many US space firms therefore buy or partner in Europe.

This guide explains how the rule works, who can bid and why it drives space acquisitions. It then covers what your European team needs from its first day.

What is ESA geographical return?

ESA geographical return is the principle that contracts follow contributions. Each Member State’s industry receives contracts roughly in line with its country’s contribution. Article VII of the 1975 ESA Convention requires equitable participation by all Member States, having regard to their contribution. It also tells ESA to grant preference to industry in all Member States.

People in the European space industry also call it georeturn, geo-return or juste retour. It sits at the centre of ESA industrial policy. Annex V of the Convention then turns the principle into rules. In placing all contracts, ESA gives preference to industry and organisations of its Member States. Within optional programmes, the countries that pay for the programme get particular preference.

In 2026, ESA lists 23 Member States on its membership page. Slovenia became the 23rd on 1 January 2025. Three members, the United Kingdom, Norway and Switzerland, sit outside the EU. Canada also takes part in some programmes under a cooperation agreement. The United States is not a member, so US-based industry receives no such preference.

How is the ESA geographical return coefficient calculated?

Each Member State has an overall return coefficient. It divides the country’s share of the value of all ESA contracts by its share of contributions. Annex V of the Convention calls a coefficient of 1 the ideal. Moreover, the ESA Council may set a lower limit for each review period, but never below 0.8.

ESA’s industrial policy page calls this ratio the industrial return coefficient. Two details matter for bidders. First, ESA weights contract values by their technological interest, so contracts do not all count equally. Second, ESA computes the coefficients every quarter. Formal reviews take place every five years, with an interim review before the end of year three.

When a country trends below its lower limit, the Director General must propose remedies. Those remedies take precedence over ESA’s normal rules for placing contracts. As a result, nationality can shape a bid team as much as capability does.

Rule	Where it is set	What it means for a US company
Preference for Member State industry	ESA Convention, Article VII and Annex V, Article II	A US-only company starts without any preference
Test of where an enterprise belongs	Annex V, Article II.3	Registered office, decision-making, research and work location all count
Overall return coefficient, ideal of 1	Annex V, Article IV	ESA spreads work across countries to match contributions
Lower limit, never below 0.8	Annex V, Articles IV and V	Remedies for countries below the limit override normal contracting rules
Nationality limits in tenders	ESA guidance for suppliers	Consortia may include only companies from named countries

Who can bid for ESA contracts?

In practice, ESA contracts go to enterprises that belong to an ESA Member State. Annex V judges this by four criteria. These are the registered office, the decision-making centres, the research centres and where the work takes place. In doubtful cases, the ESA Council decides whether an enterprise counts as belonging to a Member State.

ESA tenders add a further filter. According to ESA’s guidance for suppliers, invitations to tender often name the countries whose companies may bid. Consortia must then include companies only from those countries. The Council can also decide whether, and how far, ESA may depart from the preference rule. For that reason, under ESA geographical return, ESA contracts for non-European companies remain the exception.

Notably, the test looks at substance: offices, decisions, research and work on Member State territory. A European subsidiary that exists only on paper may not meet it. Whether a specific structure qualifies depends on the facts, so take legal advice before you bid.

Why does ESA geographical return push US space companies to buy in Europe?

Buying or partnering gives a US company a European base that can compete for ESA work. An acquired company brings its registered office, engineers, track record and place in national supply chains. A partnership also opens the door, although the European partner then holds the ESA relationship. Meanwhile, a larger ESA budget raises the stakes.

Member States subscribed €22.3 billion at the Ministerial Council in Bremen, ESA reported on 27 November 2025. ESA updated the release on 2 December 2025 with final figures. It called them the largest contributions in its history. Under geographical return, the contracts this money funds go mainly to industry in the subscribing countries.

Three routes are common for US companies that want to expand to Europe:

• Acquire a European company that already works on ESA programmes or for European primes.
• Set up a European subsidiary with real decision-making and engineering capacity.
• Partner with a European prime contractor or supplier, often as a subcontractor.

Public deals show the first route. On 1 September 2026, US space supplier Canopy Aerospace & Defense announced that it had acquired Aviotec. Aviotec makes satellite components near Turin, Italy. It made the purchase through Canopy International B.V., its Amsterdam-based subsidiary for European operations. The release does not mention ESA. Still, it shows one structure US buyers use: a Dutch subsidiary that acquires the European business.

The Netherlands also hosts ESTEC in Noordwijk, which ESA describes as the largest of its sites.

What does the European team need on Day 1?

From Day 1, the European team needs a lawful employer and a compliant payroll. Staff from outside the EU also need the right permits. Classified programmes may need security clearances as well. So plan these at signing, not at closing. Until closing, the target still belongs to the seller, so your own people need their own employer.

• Employer. In the Netherlands, the usual routes are a Dutch BV, non-resident employer registration or an employer of record. Our guide to who employs your people between signing and closing compares them. Each route still raises permanent establishment questions for the US parent.
• Payroll. A foreign company that employs staff in the Netherlands registers as an employer with the Dutch Tax Administration. Our loonheffingennummer guide explains the steps.
• Permits. US engineers count as third-country nationals in the EU. Most therefore need a residence permit to work in the Netherlands. The highly skilled migrant permit requires an employer that is an IND recognised sponsor, as Octagon is. The IND’s legal decision period for this application is 90 days.
• Clearances. Some space programmes involve classified information. In the Netherlands, designated positions of trust require a VGB, a certificate of no objection. Our guide to BPSS, SC and DV clearance explains the UK and Dutch checks.
• Limits before closing. Until the deal closes, the buyer cannot direct the target’s staff. Our article on what HR can do before a deal closes sets out the line.

Is ESA geographical return changing?

Slowly, and only in part. In June 2024, ESA’s Council took a first step towards more flexible geographical return, SpaceNews reported. ESA planned to test the approach on pilot programmes first. The principle itself remains in the Convention. Furthermore, ESA’s release on the 2025 Ministerial Council announced record funding but no change to the rule.

Member States have long disagreed about the trade-off. Some argue that georeturn causes inefficiency and delays. Others warn that a looser rule could reduce their willingness to fund ESA programmes. For now, a US company planning ESA work should assume that European presence still matters. In the meantime, watch the pilot programmes, because they will show how far the flexibility goes.

Building a European team for ESA work

In short, ESA geographical return makes ESA work depend on where your people sit and who employs them. We have helped international organisations move and employ people across borders since 1987. Our link with ESA goes back to 1990, when we delivered paperless office projects for the agency.

We employ your people in the Netherlands until your entity is ready, then transfer them. You decide salaries, benefits and working arrangements, while we carry the employment administration and its compliance risk.

Frequently asked questions

What is geographical return at ESA?

Geographical return is ESA’s policy of matching each Member State’s share of contracts to its share of contributions. ESA tracks it with a return coefficient, where 1 is the ideal. The rule comes from Article VII and Annex V of the 1975 ESA Convention. It covers all agency contracts, from research to large missions.

Can a US company win ESA contracts?

Rarely as a US-only entity. ESA prefers enterprises that belong to its Member States, judged by registered office, decision-making, research and work location. Many tenders also restrict bidders to named countries. A US group therefore tends to compete through a European subsidiary, an acquired company or a European partner. Counsel should confirm each structure.

Why do US space companies buy European firms?

A European firm can bid for ESA work and count towards its country’s return, which a US entity cannot. It also brings engineers, customers and a place in European supply chains. According to ESA, Member States subscribed a record €22.3 billion in November 2025. Access to ESA programmes is therefore a larger prize.

How many member states does ESA have?

ESA has 23 Member States in 2026, according to its membership page. Slovenia joined as the 23rd on 1 January 2025. Three members sit outside the EU: the United Kingdom, Norway and Switzerland. In addition, Cyprus, Latvia, Lithuania and Slovakia are Associate Members, and Canada cooperates under a separate agreement.
