A foreign acquirer completing a deal in Sweden without filing a mandatory notification now faces the risk of unwinding the transaction entirely. Sweden's investment screening legislation entered a significantly expanded phase, imposing pre-closing notification obligations on a broad range of foreign investments in sensitive sectors. International companies active in Swedish capital markets, defence supply chains, and critical infrastructure must act before completing any qualifying transaction.
Sweden's foreign investment screening rules now require mandatory pre-closing notification for qualifying investments by non-Swedish acquirers in protected sectors. The obligation applies when a foreign investor acquires a defined ownership threshold – or significant influence – in a Swedish company operating in a covered activity. Failure to notify before closing can result in the transaction being prohibited or declared void.
This alert sets out what changed, which business categories are affected, what the compliance deadlines are, and the immediate steps international companies should take.
What changed and when it took effect
Sweden enacted its dedicated foreign direct investment screening regime under investment legislation that came into force in stages. The most recent and consequential expansion broadened the list of protected sectors and lowered the ownership threshold triggering mandatory notification. Previously, many transactions in commercially sensitive but non-military sectors fell outside the screening perimeter. That gap is now closed.
The expanded rules apply to transactions completed on or after the effective date of the most recent amending legislation. Transactions signed before the effective date but closing afterward are also subject to the new regime. Investors who assumed that an exchange of contracts before the cutoff date exempted them from notification obligations should obtain specific legal advice before proceeding to closing.
The screening authority in Sweden is the Inspektionen för strategiska produkter (ISP – the Inspectorate of Strategic Products), which now administers the civil investment screening process alongside its existing export control and defence-related functions. ISP has the power to approve, approve with conditions, or prohibit a notified transaction.
The review period following a complete notification submission runs up to several months, depending on whether ISP requires a deeper assessment. Investors must factor this window into their deal timetable. Closing before ISP clearance is granted is not permitted for notifiable transactions.
Sweden's regime is aligned with the EU's foreign investment screening regulation, which requires member states to share information on transactions that may affect projects or programmes of EU interest. A transaction cleared by ISP may still be subject to EU-level coordination. International investors accustomed to bilateral deal processes must account for this parallel layer.

Who is affected and what triggers the obligation
The notification obligation applies to foreign investors – meaning any natural person or legal entity not established in Sweden – who acquire ownership or influence in a Swedish company carrying out a protected activity. EU-domiciled entities are not automatically exempt. A company incorporated in Germany or Portugal may still be treated as a foreign investor if its ultimate beneficial owner is a non-EU national or non-EU entity.
Ownership thresholds triggering mandatory notification include acquisitions of ten percent, twenty percent, twenty-five percent, fifty percent, and seventy-five percent of shares or voting rights. Each threshold is an independent trigger. An investor crossing from nine percent to eleven percent in a single transaction must notify. An investor who already holds fifteen percent and acquires a further six percent must notify again upon crossing twenty percent.
The protected sectors now covered include:
- Defence and dual-use goods production and distribution
- Critical infrastructure – including energy, transport, water, and digital systems
- Sensitive technology, including cybersecurity, AI, and semiconductor development
- Processing and handling of sensitive personal data at scale
- Critical raw materials and mining activities
The definition of "sensitive technology" is broad. An investment fund or venture capital vehicle investing in a Swedish technology startup may trigger the obligation even where the target company has no defence contracts and no current government clients. The determining factor is the nature of the activity, not the company's current customer base.
IPO-related acquisitions and secondary market transactions can also trigger screening where they result in a non-Swedish investor crossing a relevant threshold in a listed company active in a protected sector. Securities offering structures that involve significant share transfers to non-Swedish entities require specific disclosure obligations analysis before launch. For lending and acquisition financing in these sectors, our banking and finance advisory for Sweden covers the relevant structural considerations.

Immediate actions for international companies
International investors and their counsel should take the following steps without delay.
First, audit current and pipeline transactions. Any pending acquisition, joint venture entry, or secondary purchase involving a Swedish target must be assessed against the protected sector list and the ownership thresholds. This includes deals already signed but not yet closed. An investment fund with a portfolio including Swedish assets should review each holding for cross-threshold events, including internal reorganisations that change the formal acquirer entity.
Second, determine the correct notification category. Sweden's investment screening legislation distinguishes between transactions requiring mandatory notification and those eligible for voluntary notification. The voluntary route applies where there is genuine uncertainty about whether a protected activity is involved. Filing voluntarily creates legal certainty and protects against post-closing challenge. Omitting a filing where one was arguably required creates significant enforcement exposure.
Third, prepare the notification file in advance. ISP requires detailed information about the acquirer's ownership structure, ultimate beneficial owners, the target's activities, and the purpose of the acquisition. Gathering this documentation – particularly for complex group structures with multiple layers of ownership – takes time. Starting this process after signing but before closing is the minimum acceptable approach. Starting it during due diligence is better.
Fourth, build the ISP review period into the deal timetable. Condition precedent provisions in transaction documents should expressly include ISP clearance. Longstop dates should be set with sufficient margin to accommodate the review window, including a potential extended review phase. Deal counsel unfamiliar with the ISP process may underestimate the realistic timeline.
Fifth, assess the EU coordination dimension. Where the target company has activities or assets that connect to EU-level programmes. such as energy interconnection infrastructure. Cross-border digital systems. Alternatively, defence procurement. the transaction may be referred for EU-level review in parallel with the Swedish national process. This does not restart the Swedish timeline but may require additional documentation and engagement with European Commission officials. Engaging a lawyer in Sweden with cross-border capital markets experience is essential for managing this dimension effectively.
Companies considering prospectus filings, securities offering structures, or listing requirements for Swedish-listed entities that involve non-Swedish investors should also assess whether the transaction triggers screening obligations before any public disclosure is made. Disclosure obligations under securities legislation are separate from and run in parallel to investment screening notification requirements. Integrating both processes requires early coordination between capital markets counsel and regulatory counsel. Investors using an investment fund structure to aggregate positions in Swedish listed companies should treat screening analysis as part of standard pre-investment due diligence.
