Estonia Foreign Investment Reliability Assessment Act (VUHS) — first horizontal FDI screening regime

Mechanism

The VUHS Act is Estonia's first horizontal statutory FDI-screening regime. Prior to 1 September 2023, Estonia had no general FDI-control law; protective review was limited to narrow sectoral statutes (e.g. the Electronic Communications Act, the Defence Forces Act provisions on real-estate acquisitions in border areas, and the Securities Market Act for prudential authorisation of qualifying holdings in financial institutions).

The Act applies to foreign investors — defined as third-country (non-EU/EEA/Swiss) natural persons, legal persons, or undertakings under third-country control — acquiring a qualifying holding (as defined in § 9 of the Securities Market Act) or material influence (including a seat on the management or supervisory board, or sufficient voting rights to direct strategic decisions) in an Estonian "target undertaking."

Target undertakings include:

• Vital service providers (defined under the Emergency Act — energy,

district heating, electronic communications, payment services, etc.)

• State-owned companies designated by Government regulation
• Manufacturers or suppliers of military goods or dual-use items
• Media service providers and news publishers with annual turnover of

€3 million or more

• Critical raw materials extraction undertakings
• National defence infrastructure operators
• Communications-mast operators (masts ≥ 200 metres in height)
• Railway, aerodrome, and maritime-port operators

Investors must apply to TTJA before completion. TTJA conducts an inter-agency reliability assessment in consultation with the Estonian Internal Security Service (Kaitsepolitseiamet), Police and Border Guard Board, Defence Forces, and other security and sectoral authorities. TTJA can authorise, condition, prohibit, or order unwinding of transactions that threaten Estonian security or public order. Non-compliance levies under § 24 of the Act carry an upper limit of €100,000; additional sanction instruments include compulsory divestment orders and transaction unwinding through civil court proceedings.

Downstream implications

• Closes a frontline-NATO/EU coverage gap. Estonia is a primary

external border of the EU and NATO with Russia, hosts substantial cyber-defence and digital-government infrastructure (e-Estonia, NATO CCDCOE in Tallinn), and is a significant venue for Nordic-Baltic FDI flows; the prior absence of a horizontal regime was a material EU-coordination gap.

• Aligns Estonia with the wave of CEE/Baltic/Nordic EU member-state

transpositions of Regulation 2019/452 — Czechia (Act 34/2021), Hungary (LVIII/2020 and successor regimes), Slovakia (Act 497/2022, in force 2023-03-01), Romania (OUG 46/2022 / Law 164/2023), Lithuania (Law on Protection of Objects of Importance to National Security as amended), Latvia (National Security Law / FDI amendments).

• Real-world transaction friction concentrated in defence-tech,

cybersecurity, electronic-communications, and critical-mineral exploration deals where third-country (especially Chinese or Russian-linked) acquirers must now obtain TTJA clearance before closing.

• TTJA gains a new strategic-economic-security competence, expanding

its remit from consumer protection and technical regulation into national-security screening, consistent with the Nordic small-state pattern of housing FDI screening in technical regulators rather than in security or trade ministries.

Open questions

• Volume and outcome distribution of TTJA reliability assessments

since 1 September 2023 — number of mandatory notifications, conditional clearances, prohibitions, and ex officio reviews.

• Coordination with the EU FDI cooperation network under Articles 6

and 7 of Regulation 2019/452 — frequency of opinions received and issued.

• Whether the €3 million media-turnover threshold and the 200-metre

communications-mast threshold capture material cross-border deals in practice, or whether subsequent amendment will broaden coverage.

• Interaction with Estonia's outbound-investment screening

considerations as the EU advances its work on outbound-FDI coordination.
