Adjusted EBITDA, adjusted EBITDA margin, adjusted net income, adjusted basic EPS, adjusted diluted EPS, net working capital and net sales on a constant currency basis are non-IFRS measures used by us to evaluate our performance. Furthermore, we believe these non-IFRS measures enhance investors' understanding of our financial and operating performance from period to period because they enhance the comparability of results between each period, help identify trends in operating results and provide additional insight and transparency on how management evaluates the business. Adjusted EBITDA, adjusted EBITDA margin, adjusted net income, adjusted basic EPS, adjusted diluted EPS, net working capital and net sales on a constant currency basis should not be considered in isolation or as a substitute for other financial measures calculated and presented in accordance with IFRS.

Excluding share-based compensation, SG&A expenses as a percentage of net sales increased to 47.1% in the three-month period ended September 30, 2025, compared to 46.0% for the three-month period ended September 30, 2024.

The drivers for the fluctuations in SG&A expenses, mostly denominated as a percentage of net sales, can be summarized as follows:

• Distribution expenses as a percentage of net sales decreased to 10.4% during the three-month period ended September 30, 2025 compared to 11.9% during the three-month period ended September 30, 2024. This was primarily attributable to lower warehousing and delivery costs resulting from operational efficiency gains during the three-month period ended September 30, 2025.

• Selling expenses as a percentage of net sales increased to 8.2% during the three-month period ended September 30, 2025 compared to 7.0% during the three-month period ended September 30, 2024. The increase was primarily driven by additional expenses incurred as a result of our expanding retail footprint, primarily due to retail store-related personnel costs and depreciation.

• Marketing expenses as a percentage of net sales increased to 12.3% during the three-month period ended September 30, 2025 compared to 10.3% during the three-month period ended September 30, 2024. The increase was primarily driven by a strategic shift in the timing of our marketing campaigns partially offset by strong net sales growth.

• Share-based compensation expense as a percentage of net sales decreased to 2.9% during the three-month period ended September 30, 2025 compared to 3.1% during the three-month period ended September 30, 2024.

• General and administrative expenses as a percentage of net sales decreased to 16.2% during the three-month period ended September 30, 2025 compared to 16.8% during the three-month period ended September 30, 2024. This decrease is primarily driven by strong net sales growth and a one-time charge in relation to employee benefit contributions in three-month period ended September 30, 2024.

  Nine-month period ended September 30, 2025 compared to the nine-month period ended September 30, 2024

  SG&A expenses for the nine-month period ended September 30, 2025 increased by CHF 253.4 million, or 29.1%, to CHF 1,123.8 million, compared to CHF 870.4 million for the nine-month period ended September 30, 2024. Excluding share-based compensation, SG&A expenses as a percentage of net sales decreased to 47.4% in the nine-month period ended September 30, 2025 compared to 47.7% for the nine-month period ended September 30, 2024.

  The drivers for the fluctuations in SG&A expenses, mostly denominated as a percentage of net sales, can be summarized as follows:

• Distribution expenses as a percentage of net sales decreased to 10.9% during the nine-month period ended September 30, 2025 compared to 12.7% during the nine-month period ended September 30, 2024. This was primarily attributable to lower warehousing and delivery costs resulting from operational efficiency gains during the nine-month period ended September 30, 2024.

• Selling expenses as a percentage of net sales increased to 8.2% during the nine-month period ended September 30, 2025 compared to 7.0% during the nine-month period ended September 30, 2024. The increase was primarily driven by additional expenses incurred as a result of our expanding retail footprint, primarily due to retail store-related personnel costs and depreciation.

• Marketing expenses as a percentage of net sales slightly increased to 11.8% during the nine-month period ended September 30, 2025 compared to 11.5% during the nine-month period ended September 30, 2024. The slight increase was driven by higher marketing spend on upper funnel brand building initiatives and brand partnerships.

• Share-based compensation expenses as a percentage of net sales decreased to 2.1% during the nine-month period ended September 30, 2025 from 3.1% during the nine-month period ended September 30, 2024.

• General and administrative expenses as a percentage of net sales was equal to 16.4% during both the nine-month periods ended September 30, 2025 and 2024.

Thereof, depreciation and amortization expenses attributable to right of use assets increased by CHF 4.4 million primarily as a result of the expansion of our retail stores and our enhanced warehouse and distribution facilities. In addition, depreciation and amortization expenses attributable to owned assets increased by CHF 0.3 million.

Nine-month period ended September 30, 2025 compared to the nine-month period ended September 30, 2024

Depreciation and amortization expenses during the nine-month period ended September 30, 2025 increased by CHF

Three-month and nine-month periods ended September 30, 2025 compared to the three-month and nine-month periods ended September 30, 2024

Financial income for the three-month period ended September 30, 2025 increased by CHF 2.1 million to CHF 8.1 million when compared to the three-month period ended September 30, 2024. Financial income for the nine-month period ended September 30, 2025 increased by CHF 5.8 million to CHF 22.9 million when compared to the nine-month period ended September 30, 2024. The increase in the three and nine-month periods ended September 30, 2025 was primarily driven by an increase in the underlying amount of short-term investments.

Financial expenses for the three-month period ended September 30, 2025 increased by CHF 1.7 million to CHF 8.1 million, compared to CHF 6.5 million for the three-month period ended September 30, 2024. Financial expenses for the nine-month period ended September 30, 2025 increased by CHF 4.5 million to CHF 21.8 million, compared to CHF 17.2 million for the nine-month period ended September 30, 2024. The increase in the three and nine-month periods ended September 30, 2025 was primarily driven by higher interest expenses on lease contracts, resulting from additional leases outstanding throughout the three and nine-month periods ended September 30, 2025, compared to the three and nine-month period ended September 30, 2024.

Foreign exchange gain / (loss) for the three-month period ended September 30, 2025 resulted in a foreign exchange loss of CHF 6.1 million, compared to a foreign exchange loss of CHF 42.6 million for the three-month period ended September 30, 2024. Foreign exchange gain / (loss) for the nine-month period ended September 30, 2025 resulted in a foreign exchange loss of CHF 160.5 million, compared to a foreign exchange gain of CHF 29.7 million for the nine-month period ended September 30, 2024. The changes to foreign exchange gain / (loss) were primarily due to foreign exchange rate revaluation effects, primarily driven by the CHF/USD exchange rate. The total unrealized foreign exchange loss for the nine-month period ended September 30, 2025 was CHF 109.4 million.

‌Income Taxes Three-month period ended September 30, Nine-month period ended September 30,

(CHF in millions) 2025 2024 % Change 2025 2024 % Change

Income tax benefit / (expense)	0.3	0.9 (66.7)%	(0.6)	(35.4) (98.3)%
Effective income tax rate	(0.2)%	(3.0)% (92.0)%	0.4 %	18.8 % (97.8)%

Income tax (expense) / benefit, based on an estimate of the annual effective income tax rate for the three and nine-month periods ended September 30, 2025, was CHF 0.3 million and CHF (0.6) million, respectively. This compares to income tax (expense) / benefit of CHF 0.9 million and CHF (35.4) million for the corresponding periods in 2024. The effective income tax rate was (0.2)% and 0.4% for the three and nine-month periods ended September 30, 2025, respectively, compared to (3.0)% and 18.8% for the three and nine-month periods ended September 30, 2024 respectively. The decreases to the effective income tax rates were mainly due to deferred income tax benefits during the three and nine-month periods ended September 30, 2025 related to the elimination of intercompany profits in inventory as well as higher effectiveness of certain tax incentives and prior year adjustments.

‌Liquidity and Capital Resources

Our primary need for liquidity is to fund working capital requirements, capital expenditures, lease obligations and for general corporate purposes. We finance our liquidity needs using a combination of cash and cash equivalents balances and cash provided from operating activities.

‌Cash Flows Nine-month period ended September 30,

(CHF in millions) 2025 2024 Change

Cash inflow from operating activities	246.4	341.8	(95.4)

(1) As of September 30, 2025 and December 31, 2024, cash and cash equivalents includes restricted cash in the amount of CHF 0.9 million and CHF 0.6 million, respectively.

Operating activities

Cash inflow from operating activities for the nine-month period ended September 30, 2025 decreased by CHF 95.4 million to CHF 246.4 million compared to CHF 341.8 million for the nine-month period ended September 30, 2024. This decrease is mainly driven by a decrease in cash flows from changes in working capital of CHF 143.3 million, primarily due to changes in trade payables and inventories as well as a decrease in cash flows from changes in other current assets and liabilities of CHF

73.7 million, partially offset by higher net income after adjustments of CHF 161.4 million and various other offsetting decreases and increases.

Investing activities

Cash outflow from investing activities for the nine-month period ended September 30, 2025 increased by CHF 4.8 million to CHF 50.0 million, compared to CHF 45.2 million for the nine-month period ended September 30, 2024.

Financing activities

Cash outflow from financing activities for the nine-month period ended September 30, 2025 increased by CHF 18.5 million to CHF 58.3 million, compared to CHF 39.8 million for the nine-month period ended September 30, 2024. The increase is primarily driven by higher repayments of lease liabilities of CHF 14.0 million resulting from new retail stores, offices, and warehouses.

‌Net Working Capital

Net working capital is a financial measure that is not defined under IFRS. We use and believe that certain investors and analysts use this information to assess liquidity and management use of net working capital resources. We define net working capital as trade receivables, plus inventories, minus trade payables. This measure should not be considered in isolation or as a substitute for any standardized measure under IFRS.

Other companies in our industry may calculate this measure differently than we do, limiting its usefulness as a comparative measure.

Share-based compensation

As of September 30, 2025, On has recognized an increase in shareholders' equity in the balance sheet of CHF 49.7 million for share-based compensation incurred during the nine-month period ending September 30, 2025.

For the nine-month period ending September 30, 2025, we have recognized a share-based compensation expense of CHF 48.6 million pursuant to the following share-based compensation plans and programs for select employees including our group executive team and senior management team, which account for a part of the increase:

• Long Term Incentive Plan 2021

• Compensation of non-executive members of our board of directors

Share-based payments are valued based on the grant date fair value of these awards and recorded over the corresponding vesting period.

‌Indebtedness

On July 7, 2023, On entered into a CHF 700 million multicurrency credit facility agreement ("credit facility") which replaced our bank overdraft facilities previously reported. On has an option to increase the total availability of borrowings under the credit facility in an aggregate amount of up to CHF 200 million, subject to the satisfaction of certain customary conditions. We entered into the credit facility as part of our prudent financial planning strategy to create future financial flexibility to better align with the size and maturity of the Company. The proceeds of any borrowings under the credit facility may be used towards the financing of working capital requirements and for general corporate purposes, including the roll-in of certain existing bank guarantees and the issuance of new bank guarantees. The credit facility had an initial term of three years, which has been subsequently extended for a total period of two years. Subsequent to extensions, the credit facility will expire on July 7, 2028.

As of September 30, 2025 and December 31, 2024, no amounts had been drawn under the credit facility, and we do not currently expect to do so in the near term. As of September 30, 2025, we are using the credit facility to provide guarantees and letters of credit, as further discussed in the section titled "Off-Balance Sheet Arrangements."

The credit facility also contains financial covenants that depend on our consolidated equity as well as our net debt to adjusted EBITDA ratio. As of and during the nine-month period ended September 30, 2025, we were in compliance with all covenants under the credit facility.

Further, as of September 30, 2025, trade receivables and inventories with a carrying value of CHF 267.2 million and CHF

317.3 million, respectively, were pledged in relation to the credit facility.

‌Material Cash Requirements

There were no material changes outside of the ordinary course of business as of September 30, 2025 to the material cash requirements reported in our Annual Report, with the exception of the items discussed below.

Lease commitments: As of September 30, 2025, total lease commitments are CHF 172.5 million, with CHF 7.0 million, CHF 72.1 million, and CHF 93.4 million, due in less than one year, between one to five years, and more than five years, respectively. The decrease in total lease commitments as of September 30, 2025 compared to CHF 331.1 million as of December 31, 2024, relates to the automated warehouse in the United States ("Atlanta warehouse"), as a result of the commencement of the remaining warehouse lease space, during the nine-months ended September 30, 2025. As of December 31, 2024, the total commitments for the Atlanta Warehouse were equal to CHF 197.2 million

Lease liabilities: As of September 30, 2025, total undiscounted lease liabilities are CHF 596.4 million, with CHF 95.2 million, CHF 288.9 million, and CHF 212.3 million due in less than one year, between one to five years, and more than five years, respectively. The total increase as of September 30, 2025 compared to December 31, 2024, relates primarily to the Atlanta warehouse, and to various new retail store leases across APAC, EMEA, and Americas regions.

‌Off-Balance Sheet Arrangements

As of September 30, 2025 and December 31, 2024, we provided guarantees and letters of credit in the amount of CHF

154.2 million and CHF 168.3 million in favor of third parties, respectively. Of the total guarantees and letters of credit outstanding as of September 30, 2025 and December 31, 2024, CHF 154.2 million and CHF 168.3 million, respectively, relate to our credit facility, as discussed in the section titled "Indebtedness." Other than those items disclosed here and elsewhere in this document, we do not have any material off-balance sheet arrangements or commitments as of September 30, 2025.

‌Factors Affecting Performance and Trend Information

We expect our growth, financial condition, cash flows, and results of operations will continue to be affected by a number of factors and trends. Refer to "Item 5. Operating and Financial Review and Prospects" within our Annual Report for further information on these factors. Below, we have included recent updates.

‌Customs and duty expenses, cost inflation, consumer spending, ability to manage inventory, and foreign exchange

Beginning in April 2025, the United States ("US") implemented new tariffs as part of its trade policy, including both baseline tariffs and higher country-specific reciprocal tariffs on imports from all countries. Additionally, on July 31, 2025, an executive order ("Executive Order") was signed confirming the tariff rates on various trading partner countries, including a fixed reciprocal import tariff of 20% on Vietnam (applied in addition to the existing 20% import tariff in Vietnam). The confirmed tariff rates under the Executive Order became effective on August 8th, 2025, and have remained in effect as of the date of this report.

The tariffs in place as of the date of this report, increase the costs of products we source from outside the US and subsequently sell within the US. During the nine months ended September 30, 2025, approximately 90% and 10% of our footwear products were produced in Vietnam and Indonesia, respectively. Approximately 65% of our apparel and accessories products were produced in Vietnam, 25% in Turkey, 5% in China, and 5% in the rest of Europe. Additionally, during the nine months ended September 30, 2025 and the year ended December 31, 2024, the US market accounted for approximately 51% and 59%, respectively, of our total net sales.

The tariffs imposed since April 2025, including those in the Executive Order, have increased the costs of products we source from outside the US and subsequently sell within the US, which could adversely affect our gross margin and results of operations. While these new tariff actions did not have a significant impact on our results of operations during the nine months ended September 30, 2025, we have and expect to continue to experience increased foreign currency exchange rate volatility, which we attribute, in part, to the significant uncertainty surrounding the global trade environment.

In line with our ambition to be the most premium global sportswear brand, we continuously assess our global pricing strategy within the movements of the industry and take action where appropriate to maintain our premium brand positioning. However, pricing actions taken to maintain our brand positioning, including through raising prices, could result in reduced consumer demand and loss of market share, and could impact other factors discussed above.

These new US tariffs, retaliatory measures by other countries, and the broader uncertainty surrounding the global trade environment could also contribute to inflationary pressures, geopolitical tensions, supply chain disruptions, macroeconomic and market volatility, and uncertainty for our customers, which may increase the cost of our products and other operational costs, and negatively impact customer demand, consumer spending, and our ability to manage inventory. While the ultimate impact remains uncertain, the ongoing tariff situation could have a material adverse impact on our business, financial condition, results of operations and the price of our Class A ordinary shares.

Refer to "Item 5. Operating and Financial Review and Prospects" and "Item 3. Risk Factors" within our Annual Report for further information on these factors.

‌Non-IFRS Measures

Adjusted EBITDA, adjusted EBITDA margin, adjusted net income, adjusted basic EPS, adjusted diluted EPS, net working capital, and net sales on a constant currency basis are financial measures that are not defined under IFRS.

We use these non-IFRS measures when evaluating our performance, including when making financial and operating decisions, and as a key component in the determination of variable incentive compensation for employees. We believe that, in addition to conventional measures prepared in accordance with IFRS, these non-IFRS measures enhance investor understanding of our financial and operating performance from period to period, because they enhance the comparability of results between each period, help identify trends in operating results and provide additional insight and transparency on how management evaluates the business. In particular, we believe adjusted EBITDA, adjusted EBITDA margin, adjusted net income and net working capital are measures commonly used by investors to evaluate companies in the sportswear industry.

However, adjusted EBITDA, adjusted EBITDA margin, adjusted net income, adjusted basic EPS, adjusted diluted EPS, net working capital, and net sales on a constant currency basis should not be considered in isolation or as a substitute for other financial measures calculated and presented in accordance with IFRS and may not be comparable to similarly titled non-IFRS measures used by other companies. The tables below reconcile adjusted EBITDA, adjusted EBITDA margin, adjusted net income, adjusted basic EPS, and adjusted diluted EPS to their most directly comparable IFRS measure. See sections titled "Liquidity and Capital Resource" and "Operating Results" for reconciliations of net working capital and net sales on a constant currency basis, respectively, to their most directly comparable IFRS measure.

Adjusted EBITDA and Adjusted EBITDA Margin

The table below provides a reconciliation between net income and adjusted EBITDA for the periods presented. Adjusted EBITDA margin is equal to adjusted EBITDA for the period presented as a percentage of net sales for the same period.

Adjusted EBITDA Margin	22.6%	18.9%	20.0 %	19.2%	16.8% 14.0 %

(1) Management excludes share-based compensation expenses as we do not consider these expenses reflective of our ongoing operations and performance.

Adjusted Net Income, Adjusted Basic EPS and Adjusted Diluted EPS

We use adjusted net income, adjusted basic EPS and adjusted diluted EPS as measures of operating performance in conjunction with related IFRS measures.

For the purpose of operational performance measurement, we calculate adjusted net income, adjusted basic EPS and adjusted diluted EPS in a manner that fully excludes the impact of any costs related to share-based compensation and includes the tax effect on the tax-deductible portion of the non-IFRS adjustments, which we believe increases comparability of the metric from period to period, and makes it useful for management, our audit committee and investors to assess our financial performance over time.

Adjusted basic EPS is calculated by dividing adjusted net income by the weighted average number of ordinary shares outstanding during the period. Adjusted diluted EPS is calculated by dividing adjusted net income by the weighted average number of ordinary shares outstanding during the period on a fully diluted basis.

The table below provides a reconciliation between net income and adjusted net income, adjusted basic EPS and adjusted diluted EPS for the periods presented:
