DD in Sweden starts at the request list, before the LOI drops. The one thing most buyers miss: MBL union consultation is mandatory before signing - skip it and you're renegotiating with unions at the worst possible moment.
Sweden has clean company registries and direct advisors. Three things still bite buyers: MBL, ISP FDI screening, and ITP2.
A mid-market Swedish deal generates 3,000-15,000 documents. Set up your Ellty data room before the request list lands.
Sweden's FDI screening Act has been in force since December 2023. Phase 2 review takes up to three months - factor this in early.
MBL union consultation runs parallel to diligence on its own timeline. Trigger it at NDA signing or risk missing the original target date.
The Sweden due diligence checklist
MBL and ISP are binary checks - miss either and the deal stalls. The table below ranks areas by how badly each can hurt the deal.
Read our financial due diligence guide before scoping the numbers workstream.

Ten workstreams, ordered by how badly each can hurt the deal. Sweden-specific items - MBL, ISP, ITP2, stamp duty - span all of them.
Set up Ellty and load your documents before the request list arrives.
Corporate & legal
- Pull the Bolagsverket company extract for the target and all subsidiaries - confirms directors, shareholders, and authorized signatories.
- Review the bolagsordning (articles of association) for transfer restrictions, pre-emption rights, and voting arrangements that affect deal mechanics.
- Pull the share register (aktiebok) and check whether any shares are pledged (pantsättning); cross-check listed companies with Euroclear Sweden.
- Confirm the full cap table including share classes, convertibles, warrants, and any Teckningsoptionsprogram (employee option programs).
- Search Domstolsverket records for pending or historical litigation above a materiality threshold.
Financial
- Review three years of statutory accounts under K3 (companies with 50+ employees) or K2 for smaller entities.
- Compare K3 or K2 policies to IFRS - differences on leases, pension provisioning, and revenue recognition change EBITDA before normalization.
- Analyze pension obligations: ITP1 is straightforward but ITP2 via Alecta carries actuarial risk that can exceed the statutory accounts.
- Review periodiseringsfonder and expansionsfond - both are deferred tax liabilities booked as reserves under Swedish GAAP.
- Pull trailing 12-month bank statements and management accounts; reconcile against statutory revenue for intercompany complexity.
Tax
- Pull three years of Swedish corporate tax returns and all Skatteverket correspondence for open audits or prior settlements.
- Confirm transfer pricing documentation covers all intercompany transactions; Skatteverket scrutiny increased significantly since 2023.
- Check the NOL carryforward position and model change-of-control restrictions on usability post-acquisition under Swedish tax rules.
- Verify VAT registration, returns, and pending audits - especially for cross-border supply chains and marketplace businesses.
- Confirm deal structure early: share deals carry zero stamp duty; asset deals with real estate trigger 1.5% stämpelskatt for legal entities.
Employment & labor
- Identify all collective bargaining agreements (kollektivavtal); nearly 90% of Swedish private-sector workers are covered, and buyers assume successor liability.
- Confirm that MBL (Medbestämmandelagen) union consultation has been or will be formally triggered before signing - it is a legal obligation.
- Review key employment contracts for statutory notice periods (one to six months by tenure) and any individual severance beyond statutory minimums.
- Obtain an Alecta funding statement for any ITP2 defined-benefit obligations; deficits of several million SEK are common and typically become escrow items.
- Check for Arbetsdomstolen disputes and confirm no outstanding varsel (collective redundancy notice) requiring Arbetsförmedlingen notification.
Regulatory & licenses
- List all sector licenses: Finansinspektionen (financial services), PTS (telecoms), Energimarknadsinspektionen (energy), Medical Products Agency (pharma).
- Confirm for each license whether it survives a share deal change of control or requires regulator approval before closing.
- Check Konkurrensverket thresholds: combined Swedish turnover above SEK 1B and each party above SEK 200M triggers mandatory notification.
FDI screening
- Assess whether the target falls under Sweden's FDI Act (Lagen om granskning av utländska direktinvesteringar), in force since 1 December 2023.
- Covered sectors include defense, dual-use goods, and broadly defined essential services: logistics, data centres, food, healthcare, and telecoms.
- If screening applies, file with the ISP before closing; a deal completed without the required notification is void under Swedish law.
- Phase 1 takes 25 working days; phase 2 takes up to three months, extendable to six - build this into the schedule before heads of terms.
IP
- Pull PRV (Patent- och registreringsverket) extracts for all Swedish-registered patents, trademarks, and designs held by the target.
- Confirm IP assignment agreements exist for all founders, employees, and consultants - Swedish copyright law does not automatically assign contractor IP.
- Review inbound and outbound software licenses and confirm open-source compliance; Swedish tech targets often have complex OSS chains.
- Check whether any IP has been pledged as collateral (säkerhetsrätt) under bank or bondholder agreements.
Material contracts
- Pull the top ten customer and supplier contracts; review each for change-of-control clauses, assignment restrictions, and termination rights.
- Map contracts above SEK 5M annually and confirm renewal dates, notice periods, and exclusivity arrangements that could lapse on closing.
- Check government procurement contracts separately; Swedish LOU imposes strict limitations on contract assignment and change-of-control provisions.
- Confirm exclusive distribution or partnership agreements survive ownership change or obtain written waivers from counterparties.
Real estate & environmental
- Pull Lantmäteriet property extracts confirming ownership, encumbrances, pantbrev (mortgage deeds), and easements for all properties.
- Commission a Phase 1 environmental assessment for industrial or manufacturing sites; Miljöbalken liability follows the property, not the prior owner.
- Review all Miljöbalken environmental permits and confirm the target complies with current permit conditions.
- Confirm valid bygglov (building permits) for all structures; unpermitted construction creates liability under Swedish building regulations.
Data protection & IT
- Obtain the target's GDPR records of processing activities (RoPA), DPO appointment if required, data breach register, and privacy policies.
- Review all IMY (Integritetsskyddsmyndigheten) correspondence and any open enforcement investigations or decisions in the past three years.
- Confirm cross-border data transfers outside the EEA are covered by adequacy decisions or standard contractual clauses.
- Review NIS2 compliance documentation - Sweden transposed NIS2 in 2024, and cybersecurity gaps for in-scope operators carry regulatory liability.
How due diligence in Sweden works
The sell-side due diligence guide covers how Swedish sellers prepare. Here is how the buy-side process runs from scope to signing.
Step 1: Scope
Confirm ISP notification and MBL consultation requirements upfront. Build both into the deal schedule before heads of terms are signed. Set up an Ellty data room before the request list goes out.
Step 2: Request
Issue the document request list within 48 hours of NDA signing. Give each workstream a scoped Ellty folder so advisors start immediately.
Step 3: Review
Legal, financial, and tax workstreams run in parallel over 4-8 weeks. MBL consultation runs on its own 2-4 week track alongside review. Track reviewer activity in Ellty to catch where questions are forming.
Step 4: Flag
All findings go into a risk register: dealbreaker, adjuster, or check. ITP2 deficits and NOL restrictions cluster as price-adjusters in Sweden.
Step 5: Resolve
Swedish SPAs use indemnities for tax and escrow for pension shortfalls. ISP phase 2 review takes up to three months from a complete filing.
Swedish unions won't wait for the deal to close. MBL consultation triggered late is the most common reason Swedish transactions miss the original signing date.
M&A due diligence: how to avoid analysis paralysis (2026)
What makes Sweden deals different
MBL is a legal obligation, not a courtesy
Both buyer and seller must notify recognized unions before signing. Unions set the meeting timeline - not the employer's.
Skip consultation and unions can challenge the deal at closing. Nearly 90% of Swedish workers are covered by a kollektivavtal.
Build two to four weeks into the schedule regardless of industry. Successor liability for collective agreements is near-certain.
Share deals vs asset deals
Sweden charges zero stamp duty on share transfers. Corporate sellers pay no capital gains tax under the participation exemption.
Switch to an asset deal and real estate triggers 1.5% stämpelskatt. Model both structures with Swedish tax counsel before agreeing price.
ISP FDI screening scope
The UDI Act covers logistics, data centres, food, healthcare, and telecoms. Any deal in these sectors needs ISP notification before closing.
A deal closed without ISP notification is void - not delayed, void. Run the sector assessment before agreeing heads of terms.
Who advises on Swedish M&A
Legal counsel:
Vinge and Mannheimer Swartling lead on large Swedish M&A. Roschier, Linklaters Stockholm, and Cederquist handle mid-market well. Budget SEK 800K-3.5M for buy-side legal depending on deal size.
Employment counsel:
MBL and kollektivavtal complexity warrants separate employment counsel. Elmzell Advokatbyrå and Setterwalls cover Swedish employment M&A well. Budget SEK 150K-400K for employment diligence on deals with headcount.
Financial and tax:
Big 4 cover quality of earnings and tax on most Swedish deals. Budget SEK 500K-1.8M combined for financial and tax on a mid-market target.
Pension actuaries:
Any target with ITP2 obligations needs an independent actuarial review. Deloitte and PwC have the deepest experience with Alecta valuations. Budget SEK 120K-350K for a pension liability assessment.

Sweden deal timeline
A standard Swedish buy-side process runs 6-10 weeks from NDA to final report. The MBL union consultation track runs in parallel from week one.
Weeks 1-2: NDA signed, Bolagsverket extracts pulled, and request list issued. ISP sector assessment completed and MBL notification formally issued.
Weeks 2-4: Financial, legal, and tax reviews run in parallel. Pension actuaries engaged; ISP filing submitted if screening is required.
Weeks 4-6: Preliminary findings circulated and ISP phase 1 response received. MBL consultation concluded and management Q&A sessions begin.
Weeks 6-8: SPA negotiations on reps, warranties, and indemnities begin. W&I insurance bound; ISP phase 2 ongoing if escalated.
Weeks 8-10: Final reports issued and closing conditions confirmed. ISP and Konkurrensverket clearances received; share deed executed.

Start free 14-day trialCommon questions about due diligence in Sweden
- MBL consultation is triggered when an employer intends to make a significant change to operations, including a transfer of ownership. Both buyer and seller must notify recognized unions before the decision is made public and allow them to request a formal negotiation meeting. The union sets the meeting timeline. In practice this adds two to four weeks to any Swedish deal, and failing to consult exposes the employer to penalties and post-closing challenges.
- Yes. Sweden's FDI Act has been in force since 1 December 2023 and was expanded in September 2024. The ISP screens defense, dual-use goods, and essential services - a category broad enough to include logistics, data centres, food, healthcare, and telecoms. Phase 1 takes 25 working days; phase 2 takes up to three months. A transaction closed without the required ISP notification is void under Swedish law.
- A concentration must be notified to Konkurrensverket if the combined annual Swedish turnover of all parties exceeds SEK 1 billion and each of at least two parties has annual Swedish turnover above SEK 200 million. Swedish competition law reforms adopted in May 2026, effective August 2026, also expand Konkurrensverket's call-in powers for below-threshold mergers where competition concerns may exist.
- No. Share transfers carry zero stamp duty and the participation exemption means most corporate sellers pay no capital gains tax. Asset deals that include real estate attract stämpelskatt (lagfart) of 1.5% for legal entities. This is one of the main structural advantages of the share deal format in Sweden.
- ITP2 is Sweden's defined-benefit occupational pension for white-collar employees, administered through Alecta. Unlike ITP1, ITP2 carries actuarial risk - the employer is liable for any deficit between funded assets and future obligations. Buyers request an Alecta funding statement to quantify the deficit, which typically becomes a price adjustment, escrow item, or specific SPA indemnity.
