A foreign acquirer closing a deal in Norway without prior notification could find its transaction voided by the government. Norway has expanded its investment screening regime, introducing mandatory notification obligations that apply well beyond the defence sector. International investors – including those active in capital markets, securities offering, and investment fund structures – must now assess whether their planned acquisitions trigger a filing requirement before completion.
Norway's updated investment screening legislation introduced compulsory pre-transaction notification for foreign acquisitions that reach or exceed defined ownership thresholds in designated sectors. The obligation applies from the point at which a transaction is agreed, and notification must be submitted before closing. Failure to notify exposes the acquirer to the risk of a government review, potential conditions, and – in the most serious cases – a prohibition order or forced divestment.
This alert sets out what changed, which business categories are now in scope, the applicable thresholds, and the immediate steps international companies should take.
What changed and when it takes effect
Norway's investment screening rules are grounded in national security legislation that authorises the government to review and, where necessary, block foreign acquisitions in sensitive sectors. The most significant recent development is the extension of mandatory notification beyond the original narrow category of defence and security undertakings.
Under the expanded regime, foreign investors must notify the relevant Norwegian ministry before completing any acquisition that crosses the prescribed ownership thresholds in a covered sector. The notification obligation is not limited to non-EEA investors. EEA-based buyers – including EU and Liechtenstein entities – are also subject to the requirement where the target operates in a covered sector.
The expanded notification system entered into force in 2024 and is now operative. There is no transitional grace period for pending transactions. Any deal signed after the effective date that meets the threshold criteria must be notified before closing, regardless of whether the parties were unaware of the obligation at signing.
A key departure from prior practice is the shift from a purely voluntary, risk-based notification model to a mandatory pre-closing filing for covered transactions. The consequences of non-compliance are material: the government retains authority to intervene even after an unnotified transaction closes, including by ordering divestment.
Who is affected: sectors, thresholds, and transaction types
The mandatory notification obligation applies to acquisitions of qualifying influence in Norwegian entities operating in defined sensitive sectors. The primary sectors now covered include:
- Defence, security, and critical national infrastructure
- Energy production, transmission, and distribution
- Digital infrastructure, including electronic communications and data processing
- Water supply and other critical services
- Financial market infrastructure – an area that intersects directly with capital markets activity, IPO processes, and listing requirements
Ownership thresholds that trigger the notification duty are set at one-third, one-half, and two-thirds of the shares or voting rights in the target entity. Acquisitions that bring a foreign investor to or above any of these thresholds in a covered-sector company require advance notification. This applies regardless of whether the acquisition is structured as a direct share purchase, a subscription in a new issuance, or an indirect acquisition through a holding vehicle.
Investment fund structures deserve particular attention. Where a fund acquires a stake in a Norwegian target, the identity and origin of the fund's ultimate beneficial owners will be examined. Funds with non-EEA ultimate investors acquiring through an EEA-domiciled vehicle do not automatically avoid the screening obligation. The substance of control – not merely the legal form of the acquirer – determines whether notification is required.
Disclosure obligations already familiar from prospectus and securities legislation now run in parallel with the screening notification. Companies preparing for an IPO or a secondary listing on Oslo Børs (the Oslo Stock Exchange) must consider whether any pre-IPO foreign shareholder's stake. Alternatively. Any cornerstone investor commitment, crosses the notification threshold in a covered sector.

Immediate actions for international companies
Companies with existing or planned exposure to Norwegian assets should act promptly. The following steps address the most critical compliance risks under the new notification regime.
1. Screen your existing portfolio. Determine whether any current holdings in Norwegian entities – whether held directly or through fund or holding structures – place you at or above a notification threshold in a covered sector. An unnotified historic acquisition does not enjoy a safe harbour simply because it predates the expanded rules in all circumstances; legal advice specific to the timing and structure of each transaction is essential.
2. Review pending and pipeline transactions. Any acquisition currently in negotiation or due diligence that targets a Norwegian entity in a covered sector must be assessed for notification requirements before signing. Build the notification timeline into the deal timetable. The review period following a notification can extend to several months; failing to account for this in a purchase agreement will create closing risk.
3. Examine fund and holding structures. Where the acquirer is a fund, assess the ultimate beneficial ownership chain. Identify whether any investor in the fund whose participation is material could cause the fund's acquisition to fall within the screening perimeter. This analysis is particularly relevant for investment funds with mixed EEA and non-EEA investor bases.
4. Align with capital markets advisers. For transactions involving securities offerings, IPO processes. Alternatively, secondary market acquisitions that cross a threshold. The notification obligation sits alongside. and does not replace. existing disclosure obligations under Norwegian securities legislation and listing requirements on Oslo Børs. Coordinate investment screening counsel with capital markets counsel to avoid conflicting timelines or incomplete filings. Our team advising on capital markets matters in Norway can assist in mapping these parallel obligations.
5. Update transaction documentation. Purchase agreements, shareholders' agreements, and fund subscription documents for Norwegian targets in covered sectors should include specific representations, conditions precedent, and long-stop clauses that reflect the notification requirement. Where banking and finance arrangements are linked to the acquisition – for example, acquisition financing or pledges over Norwegian assets – the screening timeline will affect drawdown conditions as well. For the financing dimension, our banking and finance practice in Norway works closely with investment screening counsel to keep both tracks aligned.
Practitioners advising on cross-border transactions consistently note that the most common error is treating investment screening as a post-signing formality. Under the current Norwegian rules, it is a pre-closing condition. Treating it otherwise can result in a transaction that is legally complete but subject to retroactive government intervention – a risk no acquirer should accept.
Separately, international clients active in other Nordic and European screening regimes should note that Norway's approach broadly mirrors the direction taken by EU member states implementing the EU Foreign Direct Investment Screening Regulation. Experience gained in parallel Norwegian filings can usefully inform strategy in related European transactions.
