Sinch Interim Report Q3 2026 Page 2 of 22 C O M ME N T S F RO M T H E C E O Continued profitable growth with Americas as the engine Sinch’s development in the quarter represents a tale of two worlds, characterized by US-led technology spearheading global economic growth and growth for Sinch. As the US drives the profound shift that Artificial Intelligence is bringing to the global economy, we anticipate that AI and the US will continue to serve as a catalyst of accelerated demand for our API products across messaging, email and voice. At the same time, our traditional SMS and Applications businesses predominately in EMEA and APAC experience weaker demand. In this landscape, Sinch is strategically positioned to win. With roughly two-thirds of our business anchored in the US, APIs remain our core capability, supported by our market-leading, enterprise- grade infrastructure. Leveraged by our deep relationships with leading technology customers, we are actively advancing our product portfolio to ensure we remain the definitive customer communications infrastructure layer for the AI economy. Advancing AI-powered customer communications Sinch has three priorities in AI: • Win the AI natives. Become the communications partner of choice for AI-native companies and application builders. • Develop our products for an AI-enabled world. Bring product experiences to market that was previously not possible. • Reimagine work. Use AI to drive productivity and refocus resources to accelerate profitable growth. During the quarter, we made progress in embedding our global communications network directly into the emerging AI-driven developer ecosystem. Sinch has newly integrated its capabilities into SpaceXSI’s Grok Build (formerly Cursor), as well as OpenAI’s ChatGPT and Codex, and since before, we are also available through Anthropic Claude and Lovable. A renaissance in voice is emerging in the US market, with demand from AI voice picking up. We have introduced Streams to our Voice API, enabling agents to respond in real time. During the quarter, we won several AI-native companies that chose Sinch for our Tier 1 connectivity and low latency. On the back of probably the strongest voice network in the US, we are well positioned to benefit from the market dynamics in enterprise and AI voice. RCS continues to gain momentum. During the quarter, we expanded our direct RCS Business Messaging connectivity to all major Tier 1 mobile operators in Canada, completing our Tier 1 RCS footprint across North America. Solid development in the quarter with Americas leading Organic net sales increased 5 percent and organic gross profit increased 4 percent, driven by Americas. Adjusted EBITDA held a stable margin at 13.7 percent, with costs being tightly managed and efficiencies in general and administrative functions being redeployed to growth investments. Adjustment items are down, cash conversion is up and the balance sheet is strengthening. In Americas, organic net sales increased 7 percent, driven by API demand across messaging, email and voice. Organic gross profit grew 10 percent, supported by Network Connectivity and the API Platform. The commercial momentum continues with new customers and expansions across our portfolio. In EMEA, our email business continued to deliver strong, double- digit gross profit growth. However, organic net sales declined 3 percent, and organic gross profit declined 2 percent, primarily due to the reduction of fixed fee operator contracts. Turning EMEA may take a few quarters, but we are making solid progress. In APAC, organic net sales increased 5 percent, driven by growth in our high-margin email business and supported by temporary low-margin traffic in messaging. However, organic gross profit declined 10 percent, due to lower margins in the traditional SMS business across Asia and the Applications business in Australia. We are taking actions to turn the development and have appointed a new leader for our business in India. Looking ahead As I reflect on my first quarter leading Sinch, I am encouraged by the strength of our customer relationships, our infrastructure and our people. Nearly half of the Fortune 100 rely on Sinch and our platform recently passed one trillion yearly interactions, making us a natural choice for enterprise-grade customer communications. In the short term, our growth is propelled by strong momentum in the US and our email business, while addressing the regional performance challenges in EMEA and APAC. In the medium term, growth is expected from acquisition of fast-growing customers, up/cross sales and increased revenue retention. Longer term, we aim to win with innovative AI powered products. We continue to sharpen our strategy. This may include acquisitions that accelerate growth and reinforce our leadership position, as well as evaluating whether some businesses could achieve greater focus and investment under different ownership. I am confident we are positioned to build on our strengths and create long-term value for our customers and shareholders. Stockholm, November 5, 2026 Jonas Dahlberg Acting CEO & CFO

Sinch Interim Report Q3 2026 Page 5 of 22 July-September Sinch’s operating segments are three regions consisting of Americas, EMEA and APAC. In addition to the segments, a complementary view with three product categories, Applications, API Platform and Network Connectivity is also presented. Net sales by segment and product category Gross profit by segment and product category Net sales amounted to SEK 7,085m (6,659) and increased organically by 5 percent YoY. Americas delivered strong organic growth, with API Platform benefiting from continued expansion across both messaging and email. This was driven by a healthy mix of customer expansions and new customer acquisitions across industries, further supported by revenue growth in US network. While EMEA and APAC combined were largely flat on revenue, APAC carried some low-margin traffic that drove temporary revenue growth, whereas EMEA experienced decline from the reduction of fixed fee operator contracts causing its overall revenue to decline. Currency effects had a positive impact of 2 percent, corresponding to SEK 110m. Gross profit was SEK 2,450m (2,318) and increased organically by 4 percent YoY. Americas achieved another quarter of solid organic gross profit growth, driving the Group’s performance. Americas growth was powered by strong gross profit expansion in Network Connectivity, driven by ongoing cost efficiencies from migrating network transmission to IP technology, alongside robust execution in API Platform messaging and double-digit email growth. With an industry-leading US voice network, Sinch is uniquely positioned to capture expanding opportunities in the enterprise voice segment business. Growth in the Americas more than offset softer performance in EMEA and APAC, where positive double-digit email growth was weighed down by regional headwinds. Currency effects had a positive impact of 2 percent, corresponding to SEK 35m. The gross margin was 34.6 percent (34.8) for the quarter. Margin expansion in Network Connectivity and flat performance in Applications was offset by margin decline in API Platform. API Platform margin was impacted by higher costs from some US telecom providers, which were passed on to customers at zero gross margin. Adjusted Opex amounted to SEK 1,482m (1,403). Adjusted Opex increased organically by 4 percent YoY, with savings from cost optimizations in general and administrative functions redirected to support growth initiatives. Currency effects increased costs by 2 percent, corresponding to SEK 26m. Opex amounted to SEK 1,537m (1,467), corresponding to an organic increase of 4 percent YoY. Currency effects increased costs by 1 percent, corresponding to SEK 7m. Adjusted EBITDA amounted to SEK 967m (915). Adjusted EBITDA increased organically by 5 percent YoY. Adjusted EBITDA was SEK 55m (64) higher than EBITDA for the quarter. The adjustments included transactional FX effects of SEK 8m (-11) and transformation costs of SEK -28m (-42). As several integration projects have reached completion during the year, transformation costs, primarily integration costs, have decreased on a YoY basis. See Note 3 for more information. Currency effects had a positive impact of 1 percent, corresponding to SEK 9m. The adjusted EBITDA margin was 13.7 percent (13.7). EBITDA was SEK 912m (851) and increased organically by 4 percent. Currency effects had a positive impact of 3 percent, corresponding to SEK 28m. The EBITDA margin was 12.9 percent (12.8). Operational EBITA amounted to SEK 801m (735). EBIT amounted to SEK 333m (242). Acquisition-related amortization reduced EBIT by SEK -413m (-428). The amortization refers mainly to acquired customer relationships and acquired software. Net financial items were SEK -69m (-69), including net interest expenses of SEK -64m (-66) and foreign exchange differences of SEK -3m (8). Net profit for the quarter amounted to SEK 196m (-10). Cash flow before change in working capital amounted to SEK 1,023m (692). Cash flow was impacted by tax paid of SEK -108m (-131) and net interest paid and received of SEK -62m (-61). Cash flow from operating activities amounted to SEK 941m (395) and was impacted by changes in working capital of SEK 82m (296). Cash flow from changes in working capital was within normal variations. Cash conversion R12M was 75%, well above the guidance over time of 40-50%. Cash used in investing activities was SEK -146m (-149) and was affected by investments of SEK -154m (-152), consisting primarily of capitalized development expenditure of SEK -123m (-115). Free cash flow amounted to SEK 787m (244) and the increase was due to change in cash flow from operating activities. Cash flow used in financing activities was SEK -738m (-358) for the quarter, which is driven by change in borrowings that reduced net cash by SEK -717m (421). The cash flow for the comparative quarter was reduced by SEK -760m due to share buybacks and purchases under the equity swap agreement related to incentive programs. Net cash flow for the quarter was SEK 58m (-111).

Sinch Interim Report Q3 2026 Page 6 of 22 Americas The Americas region is Sinch’s largest operating segment, accounting for 66 percent of consolidated gross profit. The region manages customers in both North America and Latin America. Key operational highlights. Americas continued to make commercial progress through new customer agreements, expansions of existing relationships and further development of its partner network across messaging, voice and email. During the quarter, the region secured a contract with a global cybersecurity training provider covering messaging and voice, expanded rich communication services (RCS) with a large e-commerce company and extended its work with a major telecom operator on next- generation emergency communication. The team also established new partner frameworks to support the deployment of AI-enabled communication solutions. Net sales amounted to SEK 4,593m (4,199) for the quarter. Net sales increased organically by 7 percent YoY. API Platform was the main driver, with strong growth from messaging and email. Organic sales growth benefited as cost increases from some US telecom providers were passed on to customers at zero margin. This contributed 3 percentage points to Americas YoY organic sales growth. The currency tailwind was 2 percent, corresponding to SEK 80m. Gross profit was SEK 1,625m (1,468) for the quarter. Gross profit increased organically by 10 percent, driven by Network Connectivity and API Platform. Network Connectivity delivered strong gross profit expansion, fueled by ongoing cost savings from the migration of network transmission to IP technology. The resulting margin expansion improves underlying profitability and provides financial leverage to invest and expand the enterprise portfolio. Sinch has an industry- leading voice network in the US and with voice AI redefining the market, Sinch is well positioned to capture growth in the enterprise voice segment. API Platform delivered continued growth, driven by messaging volumes and sustained double-digit growth in email. API Platform gross margin improved slightly sequentially and contracted YoY, with the decline primarily driven by the passed-on costs, which reduced Americas’ API Platform gross margin. The currency tailwind on gross profit was 1 percent, corresponding to SEK 17m. Gross margin was flat YoY at 35 percent (35). Margin expansion in Network Connectivity, together with margin improvement in Applications, was however counterbalanced by the contraction in API Platform described above.

Sinch Interim Report Q3 2026 Page 7 of 22 EMEA The EMEA region accounts for 20 percent of consolidated gross profit. The region manages customers across Europe, the Middle East and Africa. Key operational highlights. EMEA is driving its regional transformation by building commercial momentum through expansion within its existing customer base. Key developments included increased RCS adoption by a major UK financial institution and continued growth among AI-native customers across the product suite. The region also secured a partner-led RCS agreement with a Nordic outdoor apparel retailer, which is expected to become one of the first brands in the region to adopt the channel. Net sales amounted to SEK 1,523m (1,542). Adjusted for currency effects, net sales declined by 3 percent on an organic basis. EMEA net sales saw positive volume development and growth in key areas such as email and conversational messaging. However, this growth was offset by continued reduction of fixed-price supplier contracts. These contracts constitute a low single-digit share of total group revenue. The currency tailwind was 2 percent, corresponding to SEK 25m. Gross profit was SEK 496m (499) for the quarter and decreased organically by 2 percent. In API Platform, which represents slightly more than half of the EMEA business from a gross profit standpoint, the email business delivered continuous strong double-digit gross profit growth. While the shift toward conversational messaging is visible, churn from a high margin legacy product and reduction of fixed fee contracts offset the positive developments in the region. The currency tailwind was 1 percent, corresponding to SEK 6m. The gross margin was 33 percent (32).

Sinch Interim Report Q3 2026 Page 8 of 22 APAC The APAC region accounts for 14 percent of consolidated gross profit. The region manages customers throughout the Asia-Pacific region. Key operational highlights. APAC continued to secure new customers, expand existing relationships and renew contracts across Asia, Australia and New Zealand. In Southeast Asia, Sinch secured an email contract, replacing an incumbent provider, while an e-commerce marketing automation platform in North Asia selected Sinch for email and SMS services. In Australia, a major retailer expanded its existing SMS relationship to include email and a government corporation renewed its contract. Net sales amounted to SEK 970m (918) for the quarter and increased organically by 5 percent YoY. Revenue was supported by the high-margin email business which delivered strong double-digit growth. In addition, messaging carried some low-margin traffic that drove temporary revenue growth. However, this was in part offset by the continued decline in the SMS business in India. The currency tailwind was 1 percent, corresponding to SEK 5m. Gross profit was SEK 329m (351) for the quarter and decreased organically by 10 percent. In API Platform the email business continued to perform strongly, achieving double-digit YoY growth. This momentum was offset by compression in the SMS business across Asia, including India. Applications delivered continued volume growth from existing and new customer acquisition during the quarter, however margin compression continued to weigh on gross profit growth in Australia as previously communicated. APAC maintains a large presence in Applications, which represents our most profitable product set. We command a high market share in this area and remain focused on navigating market dynamics to successfully maintain the leading position. The currency tailwind was 3 percent, corresponding to SEK 12m. The gross margin was 34 percent (38), reflecting margin compression in Applications and API Platform, primarily in messaging and India SMS services.

This was offset by headwinds in EMEA and flat development in APAC, driven by the reduction in fixed fee operator contracts and decline in the Indian SMS business. Currency effects had a negative impact of 4 percent, corresponding to SEK -788m. Gross profit amounted to SEK 6,964m (7,048) and increased organically by 4 percent YoY. Americas led organic gross profit growth, supported mainly by margin expansion in the voice business driven by network cost efficiencies in Network Connectivity. Customer base diversification across both email and messaging in Americas provided healthy growth in API Platform. The solid performance in Americas mitigated gross profit contractions in EMEA and APAC. Currency effects had a negative impact of 5 percent, corresponding to SEK -353m. The gross margin was 34.1 percent (34.7) for the period. The positive impact from margin expansion in Network Connectivity and stable Applications margins was offset by lower margins in API Platform. The decline was primarily attributable to higher costs from certain US suppliers, passed on to customers at zero margin, and continued margin pressure in the Indian SMS business. Adjusted Opex amounted to SEK 4,317m (4,375). Adjusted Opex increased organically by 2 percent YoY. Continued focus on cost efficiency across functions contributed to lower general and administrative expenses YoY, while supporting investment in growth areas. Currency effects decreased costs by 4 percent, corresponding to SEK -155m. Opex amounted to SEK 4,436m (4,697), corresponding to an organic increase of 1 percent YoY. As several integration projects reached completion, integration costs decreased YoY. Currency effects decreased costs by 7 percent, corresponding to SEK -306m. Adjusted EBITDA amounted to SEK 2,647m (2,673). Adjusted EBITDA increased organically by 6 percent YoY. Currency effects had a negative impact of 7 percent, corresponding to SEK -199m. Adjusted EBITDA was SEK 119m (322) higher than EBITDA for the period. Items excluded from adjusted EBITDA included transactional FX effects of SEK 36m (-113) and transformation costs of SEK -77m (-166). Transformation costs primarily consist of integration costs, which decreased YoY. See Note 3 for more information. The adjusted EBITDA margin remained stable at 12.9 percent (13.2). EBITDA was SEK 2,528m (2,351) and increased organically by 10 percent. Currency effects had a negative impact of 2 percent, corresponding to SEK -47m, driven by SEK appreciation in relation to USD, which is Sinch’s dominant trading currency. The EBITDA margin was 12.4 percent (11.6). Operational EBITA amounted to SEK 2,191m (2,230). EBIT amounted to SEK 844m (574). Acquisition-related amortization and impairments reduced EBIT by SEK -1,228m (-1,334). The amortization refers mainly to acquired customer relationships and acquired software. Net financial items were SEK -246m (-329), including net interest expenses of SEK -199m (-207) and foreign exchange differences of SEK -38m (-107). The Group's effective tax rate was 31 percent (113). The comparison period was impacted by a reduction in deferred tax assets amounting to SEK 180m. Net profit for the period amounted to SEK 416m (-33). Cash flow for the period January-September before changes in working capital amounted to SEK 2,710m (1,797). Cash flow was reduced by tax paid of SEK -298m (-576) and net interest paid and received of SEK -193m (-210). Cash flow from operating activities amounted to SEK 2,368m (1,151) and was reduced by the change in working capital of SEK 342m (646). Cash flow from changes in working capital was within normal variations. Cash used in investing activities was SEK -451m (-485) and was affected by investments of SEK -456m (-488), consisting primarily of capitalized development expenditure of SEK -358m (-337). Free cash flow amounted to SEK 1,912m (663) and the increase was mainly due to the change in cash flow from operating activities. Free cash flow per share R12M was SEK 3.61 (1.65). Cash flow used in financing activities was SEK -1,425m (-1,078) for the period. Change in borrowings improved net cash by SEK 435m (-243), while buybacks of treasury shares and purchases under the equity swap agreement related to incentive programs reduced cash flow by SEK -1,855m (-760). Net cash flow for the period was SEK 491m (-413). Consolidated cash and cash equivalents as of September 30, 2026 amounted to SEK 683m (592). Net debt at the end of the period amounted to SEK 6,813m (5,738) and includes IFRS 16-related lease liabilities of SEK 669m (703). One of Sinch’s financial targets is that net debt over time shall be below 2.5 times adjusted EBITDA (measured on a rolling twelve-month basis, R12M). Excluding IFRS 16-related lease liabilities, net debt in relation to adjusted EBITDA R12M was 1.7x (1.4). This is an increase from the comparison period and is primarily driven by buybacks of shares.

Sinch Interim Report Q3 2026 Page 16 of 22 Other disclosures Accounting policies The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS). The consolidated interim financial report has been prepared in accordance with IAS 34 Interim Financial Reporting and the applicable provisions of the Annual Accounts Act. The interim report for the parent company has been prepared in accordance with the Annual Accounts Act and RFR 2, Accounting for Legal Entities. The accounting policies and estimation methods are unchanged from those applied in the 2025 Annual Report and should be read in conjunction with that annual report. IFRS 18 Presentation and Disclosure in Financial Statements becomes effective for annual reporting periods beginning on or after January 1, 2027 and will be applied retrospectively. The standard replaces IAS 1 and introduces new requirements for the presentation and disclosure of information in the financial statements. For the Group, the primary impact is expected to relate to the classification of income and expenses and their presentation in the financial statements, primarily the income statement and the statement of cash flow. Items expected to be affected include foreign exchange differences as well as interest income and interest expense. The Group is currently preparing for the implementation of IFRS 18. The new or amended IFRS standards applicable in 2026 and later have had no material impact on Sinch’s financial statements. Risks and uncertainties relevant to Sinch are described in the 2025 Annual Report. Related-party transactions There have been no significant changes in the relationships and transactions with related parties during the period. For more information, see the 2025 Annual Report. Risk assessment Like all businesses, Sinch is exposed to various types of risks in its operations. Growth, in combination with rapid and continuous changes in the business environment, has made it necessary to increase the focus on risks and risk management. Sinch has created an ERM (Enterprise Risk Management) process to identify and control risks and to ensure that required controls and procedures are established to safeguard the assets and interests of the company. Sinch has defined five types of risks under this framework: Strategic, Operational, Legal & Compliance, Financial and External. More information about risks and risk management is provided in the 2025 Annual Report. Outlook As a general rule, Sinch does not publish forecasts. However, geopolitical uncertainty and a dynamic macroeconomic environment continue to influence global markets. While these factors contribute to ongoing volatility in financial markets, they are not expected to have a direct impact on demand for Sinch's digital services. Sinch continues to operate from a position of strength, supported by a scalable global platform, strong customer relationships, resilient profitability and robust cash flow. Forward-looking statements This report contains statements concerning Sinch's financial position and earnings as well as statements regarding market conditions that may be forward-looking. Sinch believes that the expectations reflected in these forward-looking statements are based on reasonable assumptions. Forward-looking statements, however, include risks and uncertainties and actual outcomes or consequences may differ materially from those expressed. Other than as required by applicable law, forward-looking statements apply only on the day they are presented and Sinch does not undertake to update any of them considering new information or future events.

Social insurance costs, based on the share price and the vesting period, reduced profit by SEK -26m (-12) and resulted in an increased provision in the statement of financial position. The performance criterion of adjusted EBITDA per share amounted to SEK 1.35 (1.09) for the quarter and SEK 3.64 (3.16) for the period January-September. The potential dilutive effect from the exercise of all outstanding employee stock options and warrants with exercise price below the average share price for the period was 1.1 percent (0.5).

Sinch Interim Report Q3 2026 Page 17 of 22 Share buyback and equity swap During the first half-year of 2026, 67,728,649 shares in Sinch, corresponding to SEK 1,648 m, were bought back, supported by the mandate of the Annual General Meeting on May 22, 2025. During the first half of 2026, in accordance with resolutions at the Extraordinary General Meeting on February 19, 2026, and the Annual General Meeting on May 21, 2026, Sinch cancelled 74,211,294 and 55,468,649 shares, respectively. Both cancellations were related to the shares repurchased under the authorization granted by the 2025 Annual General Meeting. On July 22, 2026, supported by the authorization granted by the Annual General Meeting on May 21, 2026, the Board of Directors resolved to repurchase own shares corresponding to up to 10 percent of the total number of shares outstanding.

During 2025 and 2026, to hedge the expected financial exposure of LTI 2025 and LTI 2026, Sinch entered into share swap agreements with a third party. The number of shares held within the share swap agreements was unchanged during the quarter. As of the reporting date, the total number of shares issued in Sinch was 718,883,194, of which the company held 16,280,000 shares within the swap agreements. The number of shares outstanding at the end of the period was 702,603,194. Employees The average number of employees including consultants during the period January-September was 4,026 (4,118).

Sinch Interim Report Q3 2026 Page 19 of 22 Note 3. Reconciliation items related to operating profit Adjusted EBITDA and operational EBITA are used to clarify performance in underlying operations. Adjustments include transformation costs, share-based incentive program costs, transactional FX effects and other non-recurring items. Costs related to incentive programs, i.e. payroll expenses and social security contributions, are adjusted for because payroll expenses under IFRS 2 are non-cash estimates and social security costs vary with Sinch’s share price. Excluding these items from adjusted EBITDA ensures that short-term changes in the share price do not impede analysis of the underlying performance and improves comparability with cash flow. The metric previously called “Adjusted EBIT” is referred to as “Operational EBITA” as of Q1 2026, with no change to its calculation. Note 4. Provisions In the fourth quarter of 2024, a provision for other taxes of SEK 700m was recognized in accordance with IAS 37. During the first half of 2026, SEK 35m was utilized, while no amounts were utilized during the third quarter. The provision is reviewed at the end of each reporting period and adjusted to reflect the current best estimate. During the third quarter of 2026, a reclassification between current and non- current provisions was made based on a reassessment of settlement dates. As of September 30, 2026, a non-current provision for other taxes of SEK 665m (494) and a current provision of SEK 0m (206) is recognized in the Group’s statement of financial position. Note 5. Pledged assets and contingent liabilities At the end of the period, pledged assets amounted to SEK 104m (68) and contingent liabilities to SEK 26m (34). As of December 31, 2025, pledged assets amounted to SEK 94m and contingent liabilities to SEK 16m.

Purpose: Growth adjusted for acquired entities and currency effects shows underlying growth. Acquisitions are considered part of organic operations after 12 months. Gross margin Gross profit as a percentage of net sales.

Equity ratio Equity as a percentage of total assets. Free cash flow Cash flow from operating activities after net investments in property, plant and equipment and intangible assets during the period. Free cash flow per share R12M Definition: Free cash flow, past 12 months, divided by the volume-weighted average number of shares outstanding past 12 months, after dilution. Purpose: Measures free cash flow per share generated by the business. Cash conversion R12M Definition: Free cash flow divided by adjusted EBITDA, past 12 months. Purpose: Measures the free cash flow generated by the business in relation to profitability in underlying operations.

Sinch Interim Report Q3 2026 Page 22 of 22 Review Report Introduction We have reviewed the interim report for Sinch AB (publ) for the period January 1 - September 30, 2026. The Board of Directors and the President are responsible for the preparation and presentation of this interim report in accordance with IAS 34 and the Annual Accounts Act. Our responsibility is to express a conclusion on this interim report based on our review. Scope of Review We conducted our review in accordance with the International Standard on Review Engagements ISRE 2410, Review of Interim Financial Information Performed by the Independent Auditor of the Entity. A review consists of making inquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures. A review has a different focus and is substantially less in scope than an audit conducted in accordance with ISA and other generally accepted auditing practices. The procedures performed in a review do not enable us to obtain a level of assurance that would make us aware of all significant matters that might be identified in an audit. Therefore, the conclusion expressed based on a review does not give the same level of assurance as a conclusion expressed based on an audit. Conclusion Based on our review, nothing has come to our attention that causes us to believe that the interim report is not, in all material respects, prepared for the Group in accordance with IAS 34 and the Annual Accounts Act, and for the Parent Company in accordance with the Annual Accounts Act.
