Strengthened financial performance and continued market leadership

I am pleased to conclude a year where Sinch became even stronger, both financially and strategically.

In November 2024 we set out our key financial targets on organic growth and adjusted EBITDA margin. During 2025 we achieved record-high profitability having already achieved the adjusted EBITDA margin of 12-14 percent targeted for the end of 2027. We have also regained organic growth momentum and are halfway towards our target range of 7-9 percent organic gross profit growth by the end of 2027.

Reflecting our strong financial position, we have initiated our first share buyback program to distribute value to shareholders. As of the reporting date, we repurchased 8.8 percent of outstanding shares and we have convened an Extraordinary General Meeting to cancel treasury shares to enable continued share buybacks.

I am particularly pleased with our solid development in the Americas, our largest region representing 63 percent of gross profit in the quarter. We also saw continued strength of our API platform products, predominately powered by our messaging and email solutions.

Moreover, our market leadership was reconfirmed by industry analysts and for the third consecutive year, Gartner named Sinch a "Magic Quadrant Leader for CPaaS", recognizing our stable and adaptable platform with seamless integration capabilities. This recognition was echoed by both the analyst firms IDC and ROCCO.

Another quarter in the right direction

During the fourth quarter, we continued the positive development in our business, with strong profitability, solid cash flow and continued organic gross profit growth. However, nominal financials are subject to strong FX headwinds. Moreover, we are reducing low margin contracts throughout the business, supporting profitability, but negatively impacting organic revenue growth.

In Americas, we delivered strong gross profit growth, driven by our core messaging and email products. Our customer base is also expanding, further diversifying customer concentration.

In EMEA, we experienced solid underlying growth in our core messaging business, supported by stronger volumes and positive product mix, while the shift away from fixed-price contracts continues to moderate growth.

In APAC, our API messaging business delivered solid growth, while results were impacted by competitive pressure in Australia and India.

The path ahead, focusing on growth

Our vision is to connect every business, with every customer, everywhere in the world. After several years focused on integrating our offering and platforms, we are now shifting our focus further towards innovation and growth, while maintaining profitability and cash conversion within target range.

In the short term, we continue to sharpen our focus on enterprise customers and partnerships. Product growth remains centered on email, conversational messaging and our self-serve offering. This has resulted in a 260% percent year-over-year increase in RCS volumes this quarter.

For the long run, we are innovating to win in AI-powered customer communication. We are pursuing fast-growing AI companies with several already relying on our APIs. In parallel, we are developing our products to be ready for the next wave of AI-powered customer communications.

In line with this strategy, we are pleased to announce a strategic partnership with Lovable, an AI-powered platform for rapid application development. This partnership integrates our APIs directly into the Lovable Cloud, starting with our email services with the potential to expand into messaging and voice. This will provide Lovable's large and growing developer community with seamless access to our communication tools, enabling them to easily embed our technology into the AI-native applications they are building.

Looking ahead to 2026, we expect continued solid growth in Americas and in our API business. However, continued phase out of fixed price contracts in EMEA and challenging dynamics in India will continue to be a drag on top line growth during the first half of 2026.

Finally, I want to thank all Sinchers for your incredible dedication during 2025. Your commitment to our strategy has been instrumental in delivering this year of market leadership and strong financial performance.

Stockholm, February 17, 2026 Laurinda Pang CEO

For definitions of financial and operational measurements, please refer to page 28.

• 1) Adjusted EBITDA and adjusted EBIT are alternative performance measures that are not defined under IFRS. See Note 2 for reconciliation and page 28 for definitions.
• 2) The dilutive effect is not taken into account when financial performance is negative and outstanding warrants/stock options are not considered when the company's average share price is below the exercise price.
• 3) In the calculation of this APM, net debt and adjusted EBITDA are both measured excluding IFRS 16-related lease liabilities. See page 9 for comments.

4) The Sinch Board of Directors measures long-term value creation through assessment of free cash flow per share. Free cash flow per share is an Alternative Performance Measure (APM) that is intended to measure the free cash flow generated by the business. The chart above shows the development of this APM over time.

October – December 2025

Organic growth is defined as growth in local currency and excluding acquisitions. No material acquisitions or disposals have been executed in the past 12 months. Accordingly, the differences between reported and organic growth for the quarter are explained solely by exchange rate fluctuations. Additional details on financial performance are provided in the segment sections.

Net sales

Net sales amounted to SEK 6,756m (7,729), corresponding to an organic decline of 3 percent YoY. All three regions reported negative organic growth and net sales also decreased organically across all product categories. See Note 9. The organic decline is predominantly driven by a reduction of contracts with low profitability.

Currency effects had a negative impact of 10 percent, corresponding to SEK -761m.

Gross profit

Gross profit amounted to SEK 2,378m (2,582), corresponding to an organic increase of 3 percent YoY. The Americas region, which is Sinch's largest and fastest growing region, continued to develop positively and contributed to organic gross profit growth while EMEA and APAC declined. Sinch's largest product category, API Platform, representing close to 60 percent of gross profit drove organic growth for the company, fueled by positive development in messaging and email. Applications were stable, while Network Connectivity declined. The releases of COGS provisions supported Americas API positively by about SEK 60m, while provisions on revenue impacted Americas Network Connectivity negatively by approximately the same amount. These provisions and releases largely offset one another, resulting in no impact on Americas' or Sinch Group's gross profit.

A favorable product mix and improved gross margins contributed to organic gross profit growth.

Currency effects had a negative impact of 11 percent, corresponding to SEK -287m.

The gross margin was 35 percent (33), supported by a favorable product mix and improved profitability supported by reduction of low margin contracts. Margins increased in Applications and API Platform but declined in Network Connectivity. Regionally, gross margin improved in Americas and EMEA, but decreased in APAC.

{5}------------------------------------------------

Operating expenses (Opex)

Opex amounted to SEK 1,534m (2,275), corresponding to an organic decrease of 26 percent YoY. The decrease is fully driven by a one-time charge for historical tax exposure of SEK 700m in the prior year. Excluding last year's one-time charge, Opex increased organically by 7 percent. The increase is mainly driven by foreign operational exchange losses and higher personnel costs, partly offset by lower integration costs. Currency effects had a positive impact of 10 percent, corresponding to SEK 157m.

Adjusted Opex, defined as the difference between gross profit and adjusted EBITDA, amounted to SEK 1,446m (1,579). Currency effects had a positive impact of 10 percent, corresponding to SEK 155m. Adjusted Opex increased organically by 1 percent YoY. The moderate cost development is attributable to continued synergy extraction and costcontrol.

EBITDA

Adjusted EBITDA amounted to SEK 933m (1,003). Adjusted EBITDA increased organically by 6 percent YoY. Currency effects had a negative impact of 13 percent, corresponding to SEK -132m.

The adjusted EBITDA margin was 14 percent (13), driven by increased gross margin and moderate Opex increase.

Adjusted EBITDA was SEK 88m (696) higher than EBITDA. The adjustments included operational foreign exchange losses of SEK -13m (93), integration costs of SEK -29m (-71), restructuring costs of SEK -20m (-9), and a one-time charge for historical tax exposure of SEK -700m in the prior year. See the quarterly summary and Note 2 for more information.

Adjusted EBITDA/gross profit was 39 percent (39).

EBITDA was SEK 845m (307) and increased organically by 218 percent, while currency effects had a negative impact of 43 percent, corresponding to SEK 130m. The increase is fully driven by the one-time charge for historical tax exposure of SEK 700m in the prior year. Excluding this one-time charge, EBITDA decreased organically by 3 percent, mainly driven by negative operational foreign exchange losses included in EBITDA.

The consolidated EBITDA margin was 13 percent (4).

EBIT

EBIT amounted to SEK 288m (-304).

Acquisition-related amortization and impairments reduced EBIT by SEK -420m (-483). The amortization refers mainly to amortization of acquired customer relationships and acquired software.

Adjusted EBIT (EBIT excluding EBITDA adjustments and amortization and impairments of acquisition-related assets) amounted to SEK 796m (875). See the quarterly summary and Note 2 for specifications.

Other income and expense items

Net financial expenses were SEK -61m (-29), including net interest expenses of SEK -59m (-93) and foreign exchange differences of SEK -6m (65).

Net profit amounted to SEK 250m (-324).

Cash flow

Cash flow before change in working capital amounted to SEK 689m (613). Cash flow was impacted by tax paid of SEK 25m (-45) and net interest paid and received of SEK -61m (-103).

Cash flow from operating activities amounted to SEK 952m (905) and was increased by change in working capital of SEK -263m (-292). Cash flow from changes in working capital was affected by payment patterns within normal variations.

Cash used in investing activities was SEK -165m (-183) and was affected by investments of SEK -166m (-171), consisting primarily of capitalized development expenditure of SEK -114m (-100).

{6}------------------------------------------------

Free cash flow amounted to SEK 786m (734) and the change is explained by cash flow from operating activities. Cash conversion R12M was 40 percent, within the guidance of 40-50 percent.

Cash flow used in financing activities was SEK -814m (-767), where the change in borrowings improved net cash by SEK 641m (-745) and buybacks of treasury shares and purchases under an equity swap contract related to incentive programs, reduced cash flow by SEK -1 ,441m (-). Net cash flow was SEK -27m (-46).

Employees

At the end of the quarter, the Group employed 4,041 (4,077) people, including consultants. The average number of employees and consultants in Q4 was 4,072 (4,064). The average number of employees was 3,592 (3,512), of whom 33 (33) percent were women.

January – December 2025

Organic growth is defined as growth in local currency and excluding acquisitions. No material acquisitions or disposals have been executed in the past 12 months. Accordingly, the differences between reported and organic growth for the period are explained solely by exchange rate fluctuations. Additional details on financial performance are provided in the segment sections.

Net sales

Net sales amounted to SEK 27,080m (28,712). Net sales increased organically by 1 percent YoY. Applications and Network Connectivity contributed positively to organic growth.

The currency headwind was 6 percent, corresponding to SEK -1,846m.

Gross profit

Gross profit was SEK 9,426m (9,685). Gross profit increased organically by 4 percent YoY. Gross profit increased organically in all regions and all product categories. Organic growth was supported by organic net sales, a more favorable product mix, and improved gross margins.

The currency headwind was 7 percent, corresponding to SEK -644m.

The gross margin was 35 percent (34). The gross margin increased in Americas and was stable in EMEA and APAC. The gross margin increased in Applications and API Platform and was stable in Network Connectivity. The improvement in gross margin is attributable to a combination of a favorable product mix shift and improved product profitability.

Operating expenses (Opex)

Opex amounted to SEK 6,231m (7,020), corresponding to an organic decrease of 6 percent YoY. The decrease is fully driven by the one-time charge for historical tax exposure of SEK 700m in the prior year. Excluding this one-time charge, Opex increased organically by 5 percent. The currency tailwind was 6 percent, corresponding to SEK 403m.

The majority of Opex is attributable to direct and indirect employee benefits. Expenses were mainly impacted by operational currency losses compared to the same period last year.

Adjusted Opex, defined as the difference between gross profit and adjusted EBITDA, amounted to SEK 5,821 (6,099). Adjusted Opex increased organically by 2 percent. The currency tailwind was 7 percent, corresponding to SEK 398m. The moderate cost increase was achieved through continued synergy extraction and disciplined cost control.

EBITDA

Adjusted EBITDA was SEK 3,605m (3,586) and increased organically by 7 percent YoY. The currency headwind was 7 percent, corresponding to SEK -246m.

Adjusted EBITDA was SEK 410m (921) higher than EBITDA. The adjustments include integration costs of SEK -179m (-209), operational foreign exchange gains/losses of SEK -126m (137), restructuring costs of SEK -30m (-93), and a one-time charge for historical tax exposure of SEK -700m in the prior year. See the quarterly summary and Note 2 for more information.

The adjusted EBITDA margin was 13 percent (12).

Adjusted EBITDA/gross profit was 38 percent (37).

EBITDA amounted to SEK 3,195m (2,665). EBITDA increased organically by 29 percent. The increase is largely driven by the one-time charge for historical tax exposure of SEK 700m in the prior year. Excluding this one-time charge, EBITDA increased organically by 2 percent. The currency headwind was 9 percent, corresponding to SEK -241m.

The consolidated EBITDA margin was 12 percent (9).

EBIT

EBIT amounted to SEK 863m (-5,807). A goodwill impairment of SEK 6,000m attributable to the Applications product category had negative impact on EBIT in the comparison period.

Net sales, SEK

27 billion

Gross margin

{8}------------------------------------------------

Acquisition-related amortization reduced EBIT by SEK -1,753m (-7,952). The amortization refers mainly to amortization of acquired customer relationships and acquired software.

Adjusted EBIT (EBIT excluding EBITDA adjustments and amortization and impairments of acquisition-related assets) amounted to SEK 3,026m (3,066). See the quarterly summary and Note 2 for specifications.

Other income and expense items

Net financial expenses were SEK -390m (-428), including net interest expenses of SEK -266m (-464) and foreign exchange differences of SEK -113m (57).

The Group's reported tax rate was 54 percent (-3). The tax rate was negatively impacted in Q3 2025 by a reduction of deferred tax assets amounting to SEK 180M, as previously communicated. The impact has been reduced during the last quarter and for the full year nets to SEK 120m. Excluding this, the reported tax rate is 29%.

Net profit was SEK 217m (-6,413).

Cash flow

Cash flow before change in working capital amounted to SEK 2,486m (2,330). Cash flow was reduced by tax paid of SEK -550m (-348) and net interest paid and received of SEK -271m (-480).

Cash flow from operating activities amounted to SEK 2,103m (2,944). The difference is mainly explained by a change in working capital of SEK 383m during the period, while cash flow from operating activities in the comparison period was improved by a total change in working capital of SEK -614m. The comparison period had a positive impact from cancellation of certain fixed price contracts with telecom operators.

Working capital at the end of the period was within normal variations but has increased since January 1 mainly due to the previously communicated temporary increase in prepaid expenses related to a cost optimization agreement with one of our largest suppliers. The temporary increase in prepaid expenses that ensued in Q1 amounted to SEK 270m at the end of Q4. The outstanding prepaid balance is expected to normalize during 2026.

Cash used in investing activities was SEK -650m (-604) and was affected by investments of SEK -654m (-589), consisting primarily of capitalized development expenditure of SEK -451m (-381).

Free cash flow amounted to SEK 1,449m (2,355) and the decrease consists mainly of changes in working capital. Cash flow during the same period last year was at a very high level. Cash conversion R12M was 40 percent, which is within Sinch's guidance of 40-50 percent.

Cash flow used in financing activities was SEK -1,893m (-2,234), where the change in borrowings increased cash flow by SEK 399m (-2,133) and buybacks of treasury shares and purchases under an equity swap contract related to incentive programs reduced total cash flow by SEK -2 201m (-). Net cash flow was SEK -439m (105).

Liquidity and financial position

Consolidated cash and cash equivalents as of December 31, 2025, amounted to SEK 553m (1,083).

Net debt amounted to SEK 6,355m (6,012) and includes IFRS 16-related lease liabilities of SEK 677m (832). 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 1.6x (1.5). This is an increase compared to the prior year, primarily driven by the share buybacks during the year.

Sinch's credit facility agreement was extended and refinanced in Q3, on existing terms. The change involved a new maturity date and reduction in the size of the facility, which entails a decrease in annual financing costs.

As of December 31, Sinch had total available credit facilities of SEK 7,797m (11,357), of which the company had used SEK 4,071m (4,971). These consisted of:

• A used loan of USD 100m that matures in February 2027.

{9}------------------------------------------------

• Credit facilities of SEK 6,000m that mature in July 2028, of which SEK 3,070m had been used as of December 31, 2025.
• Bank overdraft facilities of SEK 876m (931), of which SEK 80m (45) had been used as of December 31, 2025.

In addition, there are senior unsecured bonds in the amount of SEK 500m (500) that will mature in September 2027, and commercial paper of SEK 1,654m (775) that will mature in less than 12 months.

Financial liabilities increased during the period by SEK 399m (-2,133). During the same period, the company's net debt increased by SEK 343m (-1,975).

In total, Sinch had cash and cash equivalents of SEK 553m and unused loans, credit facilities, and overdraft facilities of SEK 3,726m as of December 31, 2025.

Shares were issued in relation to employee stock options/warrants under the Group's incentive programs. See Note 4.

Equity as of December 31, 2025, amounted to SEK 22,741m (29,025), corresponding to an equity ratio of 57 percent (60).

Share buyback and equity swap

Supported by the mandate of the AGM held May 22, 2025, the Board of Directors announced on July 21 the decision to buy back shares corresponding to up to 10 percent of total shares outstanding in the company during the period prior to the 2026 AGM. The buyback is intended to adjust the company's capital and equity structure to further increase shareholder value. Sinch bought back 61,951,294 shares during the year for a total of SEK 1,881m within the framework of the previously communicated buyback program, which corresponds to 7.3 percent of total shares outstanding.

The total number of shares issued in Sinch is 845,643,560, of which the company held 61,951,294 treasury shares on December 31.

During Q3, Sinch entered into a share swap agreement with a third party, which in its own name acquires and transfers shares in Sinch to employees who participate in long-term incentive programs. The total number of shares purchased during the year was 12,000,000, with a value of SEK 364m.

Employees

The average number of employees and consultants during the period was 4,107 (4,096). The average number of employees was 3,598 (3,491), of whom 33 (33) percent were women.

Events

• Expanded a major hospitality customer from voice to global messaging, supporting secure surveys and payment links across more than 6,000 hotels in over 100 countries.
• Signed an agreement with a leading real estate technology provider to embed Sinch's messaging and voice capabilities.
• Strengthened the partnership with a global digital payments leader by replacing a legacy vendor and securing a new email agreement for critical cross-border communications.

Net sales

Net sales amounted to SEK 4,195m (4,849). Adjusted for currency effects, net sales decreased by 3 percent organically YoY. The currency headwind was 10 percent, corresponding to SEK -499m.

Gross profit

Gross profit was SEK 1,495m (1,583). Gross profit increased organically by 7 percent. The organic growth in gross profit was driven by the API Platform, supported by an expanding customer base and underlying strong development mainly in our core messaging business. Continued expansion in the enterprise segment more than offset the volume reduction with some of the largest customers, contributing to further diversification of the customer concentration.

Results in API Platform were supported by release of provisions on COGS related to prior periods, amounting to approximately SEK 60m. Network Connectivity had negative organic growth in the quarter due to a one-time reduction in revenues of approximately the same amount, SEK 60m, related to a customer dispute. The net impact of releases and provisions across categories is immaterial on total Americas Gross Profit. Performance in Network Connectivity, excluding the provision on revenue, remains stable. The currency headwind for Americas was 13 percent, corresponding to SEK -200m.

The gross margin increased to 36 percent (33), mainly driven by underlying profitability at the product level in API Platform.

Net sales

Net sales amounted to SEK 1,668m (1,838) and decreased organically by 3 percent YoY. The currency headwind was 7 percent, corresponding to SEK -122m. The organic decrease is predominately attributable to continued reduction of fixed price contracts with operators.

Gross profit

Gross profit was SEK 531m (574), corresponding to an organic decrease of 2 percent YoY. Applications continued to grow with stronger volumes and positive product mix changes. Similar to the preceding quarter, EMEA was impacted negatively on a YoY basis from reduction of fixed price contracts with telecom operators. Meanwhile, the underlying core messaging business in API platform delivered solid growth. Network Connectivity declined on a YoY basis driven by a drop in volumes. The currency headwind was 6 percent, corresponding to SEK -34m.

The gross margin increased to 32 percent (31), driven by higher profitability in Applications and a favorable shift in the product and customer mix.

Gross profit

Gross profit was SEK 352m (425) and decreased organically by 4 percent. The organic gross profit decline was mainly driven by the Applications product category, where competitive pressure weighed on results in Australia. Within API platform, strong underlying growth within our core messaging business was offset by the YoY decline in the SMS business in India. The currency headwind was 13 percent, corresponding to SEK -54m.

The gross margin was 39 percent (41). The gross margin was negatively impacted by lower profitability, primarily in Applications, reflecting market-driven increases in messaging termination costs in Australia.

Note 1. Accounting Policies

The consolidated financial statements have been prepared in accordance with International Financial Reporting Standards (IFRS). The interim report has been prepared in accordance with IAS 34 Interim Financial Reporting and the applicable provisions of the Annual Accounts Act. Disclosures in accordance with IAS 34 Interim Financial Reporting are provided in notes and elsewhere in the interim report. The interim report for the parent company has been prepared in accordance with the Annual Accounts Act, which is in accordance with RFR 2 Accounting of Legal Entities. The accounting policies and estimation methods are unchanged from those applied in the 2024 Annual Report. The financial statements are presented in SEKm unless otherwise specified. Amounts and calculations presented in the tables are rounded off and may not precisely match the figures presented in the financial statements and notes.

New standards and interpretations in 2025

The new or amended IFRS standards applicable in 2025 and later have had no material impact on Sinch financial statements. Risks and uncertainties relevant to Sinch are described in the 2024 Annual Report.

New and amended IFRS not yet effective

IASB has published the following new or revised standards, of which IFRS 18 and IFRS 19 have not yet been adopted by the EU:

• IFRS 18 Presentation and Disclosures in Financial Statements
• IAS 21 The Effects of Changes in Foreign Exchange Rates
• IFRS 9 Financial Instruments and IFRS 7 Financial Instruments: Disclosures
• IFRS 19 Subsidiaries without Public Accountability: Disclosures

In April 2024, IASB published the new IFRS 18 standard Presentation and Disclosures in Financial Statements, which will supersede IAS 1 Presentation of Financial Statements. IFRS 18, if adopted by the EU, will become mandatorily effective January 1, 2027, and will be applied retrospectively in both annual and interim reports.

The new standard introduces three areas with new requirements aimed at increasing the comparability, transparency, and usability of financial reports. The first area sets new requirements for the structure of the consolidated statement of profit or loss (statement of comprehensive income) through the introduction of three new categories and requires entities to present two new defined subtotals, "Operating profit" and "Profit before financing and income taxes." The second area introduces new principles and expanded guidance on presentation and disclosures in the financial statements, including guidance concerning how entities can determine whether information about an item should or should not be included in the primary financial statements. The third area that IFRS 18 introduces entails new requirements for disclosures about certain key figures that the company uses in its external financial communication, i.e. Management-defined performance measures or "MPMs." Consequent upon the implementation of IFRS 18, there will be amendments to other standards, such as IAS 7 Statement of Cash Flows, IAS 34 Interim Financial Reporting and IAS 33 Earnings per Share.

Sinch has begun an assessment of the impacts of IFRS 18 and will continue to assess the impacts in 2026. The implementation of IFRS 18 is going to require changes to the structure of the consolidated statement of comprehensive income (profit or loss) and assessments related to the presentation of items in the financial statements and disclosures in notes. The format of the statement of cash flows will also be affected by the implementation of IFRS 18. The implementation of IFRS 18 will also entail identification of MPMs that are relevant to the Group and

compilation of disclosures concerning these performance measures in notes.

The other amendments have been determined as having no material impact on the consolidated or parent company financial statements in the period of initial application. None of the new or revised standards have been early applied by the Group.

Receivables and accrued revenues

Accounts receivable (both billed and unbilled) have an unconditional right to payment. Revenues based on an unconditional right to payment must be reported as unbilled receivables if the amounts have not been billed as of the reporting date, while revenues that have been billed are shown as billed receivables on the balance sheet. Most customers are billed monthly in arrears (after services are rendered) and the unbilled receivables are converted to billed receivables a few days after the close of books.

Contract assets referring to accrued revenue have a conditional right to payment, which means for example that Sinch must first satisfy a final contractual obligation before an unconditional right to payment is established.

Financial assets and liabilities

Financial assets and liabilities are recognized at amortized cost, which is deemed to constitute their fair value because a majority of loan financing is carried at a three-month rate.

Related-party transactions

There have been no significant changes in the relationships and transactions with related parties compared to that disclosed in the 2024 Annual Report.

Hedging of currency risk in foreign net investments

Net investments in foreign subsidiaries are partially hedged by means of derivative instruments and foreign currency loans that are translated to the closing rate on the reporting date. Exchange rate differences arising from financial instruments used as hedging instruments in a hedge of net investments in foreign subsidiaries are recognized, to the extent the hedge is effective, in other comprehensive income and accumulated in the translation reserve in equity. When a subsidiary is sold, the cumulative value change related to the sold business and to the financial instruments used to currency hedge the net assets is moved from the translation reserve in equity to profit or loss for the year.

Share buyback

Based by the mandate of the AGM held May 22, 2025, the Board of Directors of Sinch AB announced its decision to buy back shares equal to up to 10 percent of total shares outstanding in the company. Upon buyback of treasury shares, equity is reduced by the consideration paid including any transaction costs.

Share-based payments

Sinch entered into an equity swap contract in Q3 to meet its future commitment to offer up to 12.8 million shares to participants in LTI 2025, provided vesting conditions are met. The employee incentive program is secured through an agreement to buy back own shares (total return swap). The contract with a third party entails the parent company to buy its own equity instruments (treasury shares) at a predetermined price. The equity swap contract is thus classified as an equity instrument, and the corresponding amount is accounted for as a reduction in equity. The outcome upon sale is not recognized in the income statement, but rather as a change in equity. Interest paid under the equity swap contract is recognized as a financial expense on the income statement.

{23}------------------------------------------------

Note 2. Operating profit

EBITDA and EBIT adjustments are intended to clarify performance in underlying operations. The adjustments include acquisition costs, integration costs, operational foreign exchange gains/losses, restructuring costs, costs of share-based incentive programs, and non-recurring adjustments.

The costs of incentive programs are clarified and divided into payroll costs and social insurance costs, where payroll costs are,

in accordance with IFRS 2, an estimated cost that does not affect cash flow and social insurance costs fluctuate with Sinch's price per share. Excluding these costs from adjusted EBITDA ensures that short-term changes in the share price do not impede analysis of the underlying business and makes it easier to relate adjusted EBITDA to Sinch's cash flow.

Note 3. Pledged assets and contingent liabilities

Pledged assets amounted to SEK 94m (126) and contingent liabilities amounted to SEK 16m (32) on December 31, 2025.

Note 4. Incentive programs

Within the framework of LTI 2024, adopted by the AGM on May 16, 2024, senior executives and key employees within Sinch were granted 277,500 warrants in Q1 and 250,000 employee stock options in Q2. The warrants were granted at market value corresponding to subscription prices of SEK 9.40, SEK 9.44, and SEK 9.87 for the respective series. The maximum number of instruments in LTI 2024 is 17,100,000.

Within the framework of LTI 2025 adopted by the EGM on August 14, 2025, senior executives and key employees within Sinch were granted 10,680,800 employee stock options in Q3 and 240,000 employee stock options in Q4. The maximum number of instruments in LTI 2025 is 12,800,000.

Sinch entered into an equity swap contract with a third party in Q3, 2025, to hedge the expected financial exposure of LTI 2025. As of December 31, the equity swap consisted of 12,000,000 shares corresponding to SEK 364m.

In Q4, 486,209 options from LTI 2022, 143,870 options from LTI 2023, and 105,510 options from LTI 2024 were exercised, where each option carried 1 share. The exercise prices were, for LTI 2022 SEK 14.654 and 25.33, for LTI 2023 SEK 27.13, and for LTI 2024 SEK 21.63 and 19.835 per share.

In relation to this, 319,619 shares will be registered in Q1 2026 and Sinch will thereby gain an additional SEK 5m in equity through the exercise.

The total costs of incentive programs recognized in profit or loss for Q4 amounted to SEK -10m (4). Payroll costs for vested

employee stock options in all programs were included in profit or loss in the amount of SEK -8m (-11) with a corresponding increase in equity. Social insurance costs, based on the share price and the vesting period, reduced profit by SEK -2m (15) and resulted in an increased provision in the statement of financial position.

Total costs for the incentive programs amount to SEK -46m (-37) for the period January-December, 2025. Payroll costs for vested employee stock options in all programs were included in profit or loss in the amount of SEK -33m (-53) with a corresponding increase in equity. Social insurance costs, based on the share price and the vesting period, reduced profit by SEK -14m (16) and resulted in an increased provision in the statement of financial position.

The performance criterion of adjusted EBITDA per share amounted to SEK 1.15 (1.18) for Q4 and to SEK 4.31 (4.22) for the period of January-December.

The potential dilutive effect, calculated based on the exercise price of the options in relation to the average share price during the period January-December 2025, was 0.6 percent (0.6) upon exercise of all outstanding warrants and employee stock options when the exercise price is lower than the share price on the reporting date. See Note 9 of the 2024 Annual Report for further disclosures regarding the Group's incentive programs LTI 2020, LTI II 2020, LTI 2021, LTI II 2021, LTI 2022, LTI 2023, and LTI 2024.

Note 5. Depreciation, amortization and impairments

Goodwill is tested for impairment annually in connection with updated business plans in the third quarter. Impairment tests are also performed when there is an indication that the asset has decreased in value.

There were no indications of goodwill impairment in the cash generating units in Q4 2025.

Note 12. Financial risk management

Currency risk arises in the translation of the net assets of foreign subsidiaries to the parent company's functional currency ("translation exposure"). Sinch began to apply hedge accounting in Q2 2025 in accordance with IFRS 9 with regard to net investments in foreign subsidiaries by means of raising currency loans and derivative instruments in the corresponding currency in order to reduce volatility in recognized profit or loss. No ineffectiveness in the hedging relationship had impact on profit or loss for the period. At the end of the period, net assets in USD had been hedged in the amount of USD 327m.

The translation reserve in consolidated equity includes all exchange rate differences that arise upon translation of financial statements in a currency other than SEK, which is the Group's presentation currency. As of December 31, 2025, the translation reserve on the consolidated statement of financial position includes exchange rate differences of SEK 89m, before tax, that arose upon revaluation of liabilities taken up as hedging instruments for a net investment in a foreign operation.

More information about risks and risk management is provided in the 2024 Annual Report.

{27}------------------------------------------------

Definitions

Regions

Effective January 1, 2024, the new Sinch operating model and operating segments are based on three geographical regions: Americas, EMEA, and APAC. The regions represent the domiciles of our customers.

Product categories

Sinch discloses supplementary financial information across three product categories.

Applications

This product category targets business users and consists of software applications for customer engagement, supporting use cases across marketing, operations, and customer care.

API Platform

Products within this category target developers and product managers. APIs allow businesses to trigger mobile messaging, voice calling, and emails, from their own internal or third-party IT systems.

Network Connectivity

Network Connectivity products target telecom operators and wholesale voice buyers. The portfolio primarily includes voice and messaging interconnect services, operator software, and services.

Financial measurements defined under IFRS:

Earnings per share, basic and diluted

Definition: Net profit for the period attributable to owners of the parent divided by the volume-weighted average number of shares outstanding in the period before/after dilution.

Financial measures not defined under IFRS:

The company presents certain financial measurements that are not defined under IFRS. The company believes that these measurements provide useful supplemental information to investors and the company's management for reasons including that they enable evaluation of the company's performance. Because not all companies calculate financial measurements in the same way, these are not always comparable to measurements used by other companies. These financial measurements should therefore not be considered a substitute for measurements defined under IFRS. For a reconciliation of these financial measurements and organic growth, please refer to investors.sinch.com.

Gross profit

Definition: Net sales less the cost of services sold.

Purpose: A large share of Sinch's cost of services sold consists of traffic fees paid to mobile operators. Operator traffic fees differ significantly from one country to the next. Consequently, changes in traffic patterns and the volume mix can have high impact on net sales and the gross margin even though there is no effect on gross profit in absolute numbers.

Gross margin

Definition: Gross profit in relation to net sales.

Purpose: The gross margin reflects the percentage of sales that comprises internal value creation and is not passed on to suppliers.

Gross profit growth

Definition: Gross profit for the year divided by gross profit in the preceding year.

Operating expenses (Opex)

Definitions: Opex is defined as the difference between gross profit and EBITDA and consists of the following items: Other operating income, Work performed by the entity and capitalized, Other external expenses, Employee benefits expenses, and Other operating expenses.

EBITDA

Definition: Profit for the period before financial income, financial expenses, tax and depreciation, amortization, and impairments of property, plant, and equipment and intangible assets.

Purpose: Enables comparisons of profitability over time, regardless of the effects of the rate of depreciation and amortization of non-current assets, financing structure and the corporation tax rate.

EBIT

Definition: Profit for the period before financial income, financial expenses, and tax.

Adjusted operating expenses (adjusted Opex)

Definition: Adjusted Opex is defined as the difference between gross profit and adjusted EBITDA and consists of the following items: Other operating income, Work performed by the entity and capitalized, Other external expenses, Employee benefits expenses, Other operating expenses, and EBITDA adjustments.

Sales & marketing expenses

Definition: Expenditures associated with promoting and selling our products, including acquiring new customers, and managing existing customer relationships.

Research & development expenses

Definition: Expenditures associated with the development, improvement, and technical operations of our products, net of capitalized software development.

General & administrative expenses

Definition: Expenditures for support functions such as finance, human resources, facilities, information technology, and other administrative functions.

Acquisition costs

Definition: Acquisition costs are such costs incurred as a consequence of a business combination.

Integration costs

Definition: Integration costs arise mainly in connection with business combinations and in connection with the creation of a common IT infrastructure. The nature of the costs consists of alignment of processes, brands and technical systems. The costs are of a non-recurring nature but, unlike restructuring costs, they are connected to the entity's current and future operations. As of 2024, integration costs include only external costs and resources.

{28}------------------------------------------------

Restructuring costs

Definition: Restructuring costs comprise direct costs related to restructuring and have no connection with the company's current operations. Restructuring costs include mainly the costs of laying off employees and indirect costs related to the layoffs.

Adjusted EBITDA

Definition: EBITDA excluding acquisition costs, integration costs, restructuring costs, operational foreign exchange gains/losses, costs of share-based incentive programs and non-recurring adjustments.

Purpose: Enables comparison of profitability over time in underlying operations.

Adjusted EBITDA per share

Adjusted EBITDA divided by the volume-weighted average number of shares outstanding for the period after dilution.

Purpose: Measures the earnings per share generated by the business adjusted for acquisition costs, integration costs and other adjustment items.

Adjusted EBITDA/gross profit

Definition: The measure shows the company's adjusted EBITDA as a percentage of gross profit. In addition to net sales, the cost of services sold is included in gross profit.

EBITDA margin/adjusted EBITDA margin

Definition: EBITDA/adjusted EBITDA in relation to net sales.

Amortization/depreciation of acquisition-related assets

Definition: Amortization of acquired intangible assets/depreciation of acquired property, plant, and equipment. Depreciation of property, plant, and equipment and amortization of other intangible assets are included in acquisition-related amortization/depreciation, as this is a measure of the use of resources necessary to generate profit.

Adjusted EBIT

Definition: EBIT after the same adjustments as for adjusted EBITDA and excluding amortization/depreciation and impairments of noncash acquisition-related property, plant, and equipment and intangible assets.

Purpose: Enables comparison of profitability over time, regardless of amortization/depreciation and impairment of acquisitionrelated property, plant, and equipment, and intangible assets, and independently of financing structure and the corporation tax rate.

EBIT margin/adjusted EBIT margin

Definition: EBIT/adjusted EBIT in relation to net sales.

Net margin

Definition: Net profit for the year in relation to net sales.

Purpose: The net margin is a performance indicator that indicates the size of the company's profit in relation to its turnover, which is useful to assess the efficiency of the company's operations.

Interest-bearing liabilities

Definition: Bond loans, bank loans, overdraft facilities, commercial paper, and lease liabilities.

Purpose: Used to calculate net debt.

Risk assessment

Sinch is, like all businesses, 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 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 2024 Annual Report.

Outlook

Sinch does not typically publish forecasts but acknowledges that the ongoing geopolitical and macroeconomic uncertainties will potentially continue into 2026. Recently introduced tariffs in early 2026 have further added to the unpredictability of the global market. While these tariffs initially apply to goods and do not directly affect Sinch's services, Sinch monitors developments to assess any potential indirect effects on the customers and markets. Despite challenging market environment Sinch has, during 2025, continued to deliver good underlying profitability and robust cash flows, demonstrating the resilience of the business model.
