Updated 8 October 2026.
The OMX Stockholm 30 brings together 30 of the largest and most traded shares on Nasdaq Stockholm. Its constituents include industrial groups with worldwide operations, major Nordic banks and some of Sweden’s best-known consumer businesses.
This September 2026 snapshot identifies each company’s current auditor, the first financial year under the engagement and its disclosed audit fee. Companies are listed alphabetically, but the table can be sorted by company, sector, auditor, since and audit fee.
Fees are presented in Swedish kronor, with the final column explaining currency conversions, predecessor fees and other exceptions..
A closely divided market
EY holds nine audit appointments, giving it 29.0% of the Stockholm index’s appointments. PwC and Deloitte each hold eight, or 25.8%, while KPMG holds six, or 19.4%. Every company on the index is audited by a Big Four firm.
Svenska Handelsbanken has two auditors, PwC and Deloitte. Counting both produces 31 appointments across the 30 companies.
Each network counts once per company; Alfa Laval’s two individually appointed EY auditors count as one EY appointment.
The market-share chart therefore measures each network’s share of those 31 appointments.
The distribution reflects the different types of businesses in the index. Industrials make up 13 of the 30 companies, and EY audits six of them: Atlas Copco, Alfa Laval, ASSA ABLOY, Epiroc, Lifco and Skanska. These businesses account for two-thirds of EY’s Stockholm appointments. Its remaining clients are SEB, Essity and SCA.
The financial sector has seven companies and eight audit appointments. PwC and Deloitte each hold three. PwC audits Nordea and Swedbank and shares Handelsbanken’s audit with Deloitte. Deloitte’s other financial-sector clients are Investor and Industrivärden. EY audits SEB, while KPMG audits EQT.
KPMG’s six appointments include both telecommunications companies, Tele2 and Telia, as well as ABB and AstraZeneca. Deloitte’s portfolio includes Ericsson and AB Volvo; PwC’s includes Hexagon, Sandvik and Saab. Appointment counts capture the breadth of each firm’s client list, while the names behind those counts reveal its position in particular industries.
Recent appointments alongside established relationships
Six companies have a recorded first financial year with their current auditor of 2024 or later. Deloitte’s Addtech engagement and KPMG’s appointments at Tele2 and Telia begin with financial years ending in 2024. PwC’s Boliden engagement and EY’s Lifco engagement begin in 2025.
AstraZeneca appointed KPMG at its April 2026 annual general meeting, making 2026 the first financial year of the new engagement. The company’s latest published annual fee disclosure in this snapshot still relates to PwC’s FY2025 audit.
At the other end of the table, Saab’s relationship with PwC dates from 2011. Deloitte’s Investor engagement and KPMG’s NIBE engagement date from 2013. H&M’s Deloitte engagement began in 2021. EQT’s start year is left blank because the company’s disclosures give conflicting dates. The table records the first financial year under the engagement; annual reappointments do not restart that date.
Audit fees reflect the scale of the companies
The audit fees recorded in the table total approximately SEK2.29bn, with a median of SEK57.5m. Where separately disclosed, the figures cover fees for the principal auditor’s network, excluding fees paid to other audit firms and separately identified non-audit services. Disclosed audit categories can include reviews, sustainability assurance or transaction-related audit work, as identified in the notes. Six companies account for approximately 50.6% of that total: ABB, AstraZeneca, Ericsson, Hexagon, AB Volvo and Atlas Copco.
ABB has the largest recorded fee, at approximately SEK285.5m after conversion from US dollars. AstraZeneca follows at SEK260.6m. Ericsson reports SEK181m, Hexagon’s fee converts to SEK165.6m, and AB Volvo and Atlas Copco report SEK142m and SEK125m respectively.
The largest disclosures come from international groups with substantial audit operations. The range also extends to much smaller disclosures: Industrivärden reports SEK1m. A count of audit appointments gives each company equal weight; the fee data shows how widely the financial scale of those appointments varies.
AstraZeneca’s SEK260.6m figure comes from the FY2025 disclosure for predecessor PwC’s group and subsidiary statutory audits, including USD0.8m relating to prior years. KPMG appears as the current auditor, and the table’s note identifies PwC as the recipient of the reported fee. Handelsbanken’s SEK52m figure combines SEK45m for PwC and SEK7m for Deloitte. These distinctions matter when allocating disclosed fees between audit firms.
About the data
The table uses the September 2026 research snapshot, with a full review of constituents, current auditor appointments, engagement dates and fee disclosures completed on 8 October 2026. The June 2026 Nasdaq review made no changes to the index’s constituents.
“Since” refers to the first financial year ending under the current audit engagement. Handelsbanken’s paired dates follow the same order as its paired auditors. For Nordea Bank Abp, the date reflects its first reporting period, which ended in 2018. EQT’s issuer governance and IPO documents say 2011, while its signed auditor’s report says 2012; the table leaves that date blank and explains the conflict in Notes.
Fees use the latest annual disclosure available in the research, generally FY2025, with Addtech reported for FY2025/26. The figures use separately disclosed statutory audit or audit-engagement fees for the group auditor’s network where available, excluding separately identified non-audit services and fees to other audit firms. SEB’s audit category includes quarterly reviews, and NIBE’s includes contractual reviews. ABB’s includes mandatory sustainability assurance and may include quarterly reviews and comfort letters; Epiroc’s includes sustainability audit at group level. Hexagon’s audit category includes work relating to the potential separation of Octave. Telia’s figure covers continuing operations, with no separate charge for interim reviews; its unsplit discontinued-operation remuneration is excluded. EQT’s audit-services category includes contracted examinations and agreed-upon procedures. Notes identify exceptions, including fees paid to a predecessor. The total combines company disclosures across reporting periods and currencies; allocating it by network requires the recipient and any joint-audit split to be taken into account.
Euro and US-dollar disclosures are converted to Swedish kronor using ECB reference rates at 31 December 2025. These conversions provide a common presentation currency.
