Sika delivers 4.0% local currency revenue growth and upgrades full-year growth expectations

Dear Readers,

In the first half of the year, Sika delivered 4.0% revenue growth in local currencies, with organic growth of 2.9%. In the second quarter, both local currency and organic growth accelerated compared to the first quarter, reaching 6.8% and 5.7%, respectively, with each region recording stronger revenue growth.

Our year started strongly against a muted market and geopolitical uncertainty. We delivered improved momentum, with the second quarter building on our good start to the year. Our investments in industry-leading innovation, efficient global manufacturing and sourcing, and our digital transformation allowed us to continue to gain market share throughout the first half of the year. As a result of our accelerating leadership in strategically important growth segments such as infrastructure and data centers, we expect to continue outperforming the industry.

INCREASED MATERIAL MARGIN - EBITDA MARGIN RISES TO 19.0%

In the first half of 2026, Sika posted sales growth of 4.0% in local currencies and reported sales of CHF 5.59 billion (-1.5% in CHF, including a foreign currency effect of -5.5%). Sika grew its material margin to 55.7% (2025: 55.1%). The key factors behind this increase were a sustained focus on product innovation, procurement efficiency, and pricing. Half-year EBITDA amounted to CHF 1,063.0 million (2025: CHF 1,070.4 million), representing a margin of 19.0% (2025: 18.9%).

Net profit in the reporting period amounted to CHF 552.1 million (2025: CHF 554.4 million). Operating free cash flow amounted to CHF 139.6 million (2025: CHF 181.9 million).

GAINS IN MARKET SHARE ACROSS ALL REGIONS

Sika accelerated local currency growth in the EMEA region (Europe, Middle East, Africa) to 7.7% (2025: 1.9%) in the first half of the year. Eastern Europe in particular recorded strong growth. Germany showed an improved second quarter performance. After a dip in March, the Middle East showed significant momentum in the second quarter and achieved strong double-digit growth, driven by infrastructure

investment projects. Across the EMEA region, Sika's agile and resilient supply chain has proven to be a structural advantage - deepening existing customer partnerships and accelerating new wins.

Sales in local currencies in the Americas region increased by 2.9% (2025: 3.5%). After a slow start to the year, regional performance improved in the second quarter. Infrastructure investments remained at a solid level in the first half of the year. Sika delivered strong growth across new and refurbishment infrastructure projects. Sika's growing leadership in data center projects drove another period of double-digit growth in this high-performing category. In Canada, Sika delivered strong growth through the first half of the year. Performance was mixed in Latin America, with modest growth overall.

Sales in local currencies in the Asia/Pacific region over the first half of the year decreased slightly by -2.0% (2025: -1.7%). The Chinese construction industry declined by a double-digit percentage, driven by continued weakness in residential construction. Excluding the Chinese construction business, Asia/Pacific posted good organic growth of 7.7%. Growth was strong across most of the region, with India and Southeast Asia being standouts.

IMPLEMENTATION OF FAST FORWARD ON TRACK

The implementation of Fast Forward is on track. The company has made targeted structural adjustments in China and introduced efficiency-enhancing measures in other markets. With Fast Forward, Sika is accelerating digital transformation, improving customer service, strengthening its supply chains, driving operational efficiency, and delivering on its ambition to become the digital market leader in the industry. The initiatives under Fast Forward have enabled Sika to handle recent supply chain volatility and fluctuating raw material costs effectively, thereby deepening its relationships with customers.

Sika expects to save around CHF 80 million in the 2026 financial year. The total annual savings of CHF 150 to 200 million will take full effect from 2028.

ACQUISITIONS AND INVESTMENTS

In the first half of the year, Sika concluded the acquisition of the leading Swedish mortar manufacturer Finja, strengthening its presence in northern Europe and expanding its cross-selling opportunities across the Nordics. Sika also announced the acquisition of Akkim in the first half of the year, a leading global manufacturer of adhesives and sealants based in Turkey with annual net sales of around CHF 220 million. The closing of the acquisition is expected in the third quarter of 2026.

In the first half of the year, Sika made targeted investments to expand production capacity in growth regions. New plants were opened in Bangladesh (concrete admixtures and mortar), Tanzania (concrete admixtures and mortars for East Africa), Belgium (new plant and technology center for concrete admixtures), Argentina (dry mortar), Colombia (mortar, tile adhesives, and coatings), and the USA, specifically in Florida (concrete admixtures) and New Jersey (mortar). The new highly efficient plant in Florida features the highest level of automation among all Sika admixture plants in the country. In New Jersey, Sika expanded its production capacity in the northeast region, enabling it to supply construction projects locally in major metropolitan areas with high-performance products. With its new plant and technology center for concrete admixtures in Ham, Belgium, Sika is expanding its production and innovation capacity in Europe.

Sika also established a new national subsidiary in Kyrgyzstan during the first half of the year, reinforcing its presence in Central Asia. Sika's global network now comprises 103 national subsidiaries.

SIKA ACHIEVES RECORD EMPLOYEE ENGAGEMENT SCORE OF 88, SURPASSING STRATEGIC TARGET

We are proud of the outstanding results of our Global Employee Survey. The engagement score of 88 index points reflects the exceptional motivation and commitment of our employees worldwide. In the first half of the year, our teams once again contributed to our strong results through their dedication and customer focus. Their engagement is the driving force behind Sika's success.

EBITDA MARGIN ROSE TO

19.0%

OUTLOOK

After a strong first half of the year, Sika is raising its sales growth expectations for 2026 to between 3% and 6% in local currencies. For 2026, Sika expects the global market to remain muted. For the year as a whole, Sika expects to achieve an EBITDA margin of 19.0% to 19.5%, and is comfortable with current consensus CHF EBITDA expectations.

The measures taken as part of Fast Forward to increase productivity, accelerate innovation, and digitalize the entire value chain are strengthening Sika's leading market position and delivering measurable top- and bottom-line results. Sika is confirming its medium-term strategic targets for sustainable and profitable growth as part of Strategy 2028.

Sincerely,

Sales growth and market share gains across all regions

Sika delivered strong sales growth and gained market share across all regions in the first half of 2026 despite geopolitical uncertainty and a muted market backdrop. The company continued to benefit from its focus on delivering value-adding solutions across its diversified portfolio, broad geographic footprint, and strong local presence.

Region EMEA

Macroeconomic conditions across EMEA remained uneven in the first half of the year as the conflict in the Middle East disrupted energy markets, driving higher oil and gas prices, and renewed inflationary pressures. European growth is expected to remain at around 1.2% for the year. Government investment continued to support activity across several GCC economies, particularly in the UAE, even as growth forecasts moderated following the outbreak of the war. Overall, the broader Middle East and Africa region is forecast to grow by around 2% in 2026.

Construction activity reflected the pressures felt from cost inflation and Middle East energy disruptions, as well as muted economic growth. In Western Europe, infrastructure remained more resilient than residential new-build activity, with output forecast to expand by 1.8%. Germany is returning to growth after several years of

In its largest region, EMEA, Sika achieved strong sales growth of 7.7% in local currencies (2025: 1.9%). Eastern Europe was a key growth driver. DACH also contributed positively, with Germany expected to gain momentum in the second half of the year. DIY and online channels performed well across the region, and supported demand from data centers, pharmaceutical projects, tunneling, and mining. In the Middle East, volumes rebounded strongly after a softer first quarter, supported by desalination and other water-related projects. Automotive & Industry delivered growth across Europe.

In the first quarter, Sika completed the acquisition of Finja, a leading mortar manufacturer in Sweden, strengthening its presence in northern Europe and expanding cross-selling opportunities.

In February, Sika announced the acquisition of Turkey-based Akkim, marking a major step in accelerating its global expansion in adhesives and sealants.

REGION EMEA SALES GROWTH IN LOCAL CURRENCIES

+7.7%

Region Americas

Economic conditions across the Americas held firm throughout the first half of the year. The US economy is forecast to grow by around 2.1% in 2026, supported by a solid labor market even as higher energy costs linked to the Middle East conflict added to inflation pressures, prompting the Federal Reserve to hold interest rates. Canada and Mexico are expected to expand at a more modest pace, while South America's GDP growth is forecast to slightly exceed that of the US, with Brazil, Colombia, and Peru, expected to expand.

Construction activity across the Americas was mixed. North America is forecast to return to growth in 2026 (+1.3%), with Canada slightly outpacing the US, despite ongoing tariff-related uncertainty. Infrastructure spending and data center construction remain key growth drivers. In Latin America, construction activity is expected to recover to around 3% growth despite persistent inflation and political uncertainty. Infrastructure remains the principal growth driver.

Sika's Americas region achieved sales growth of 2.9% in local currencies (2025: 3.5%). Against a backdrop of slow residential construction and stable non-residential markets, Sika gained share from its focus on delivering value-adding solutions, benefiting from remodeling and refurbishment activity, continued infrastructure investment, and commercial and industrial projects. Following a weaker first quarter in the US, business rebounded in the second quarter, driven in part by continued strong data center activity. Early

Region Asia/Pacific

Asia/Pacific is forecast to remain the world's fastest-growing region in 2026, with GDP expected to expand by around 4.1%. Performance was uneven in the first half of the year, as China faced ongoing subdued domestic demand. India maintained its strong growth momentum, driven by robust manufacturing, domestic demand, and the services sector, while growth diverged across Southeast Asia.

Construction markets across the region reflected these diverging trends, albeit with clear pockets of strength. India remains one of the region's standout construction markets, supported by large-scale infrastructure and energy investments. In China, government stimuli and rising investment in transport, energy, and advanced manufacturing are expected to support a recovery, alongside longer-term structural reforms, even as output is projected to contract by 1.0% in 2026. Amid persistent weakness in residential construction. India remains one of the region's standout construction markets, supported by large-scale infrastructure and energy investments.

For the Asia/Pacific region, Sika reported sales growth of -2.0% in local currencies (2025: -1.7%). Excluding the Chinese construction business, the region delivered strong local currency growth, led by Southeast Asia and South Asia. Vietnam was among the strongest-

performing markets, while India drove growth in South Asia. Automotive & Industry also delivered positive results, particularly on the industry side. China developed in line with expectations for the first half of the year, reflecting the ongoing weakness of the residential sector and weighing negatively on results. The company anticipates a more favorable comparison base in the second half of the year.

‌NOTES TO THE INTERIM FINANCIAL STATEMENTS‌

‌PRINCIPLES OF CONSOLIDATION AND VALUATION

The unaudited Condensed Interim Consolidated Financial Statements (hereinafter 'the Interim Financial Statements') for the first half of 2026 have been prepared in accordance with IAS 34 'Interim Financial Reporting'.

The Interim Financial Statements do not include all information and disclosures that would be required in the annual financial statements and should therefore be read in conjunction with Sika's annual Consolidated Financial Statements for the year ended December 31, 2025.

The Interim Financial Statements have been prepared according to the going-concern principle. Generally, assets and liabilities are valued at historical cost, except for financial assets and liabilities (including derivative instruments) at fair value through profit and loss and the defined benefit liability, which is measured at the present value of the defined benefit obligation less the fair value of plan assets.

The accounting standards applied conform to those valid in the previous year, with the exception of the following revised and new standards, which Sika has implemented as of January 1, 2026. The application of these standards did not have any material impact on the Interim Financial Statements of the Group:

• Amendments to IFRS 9 and IFRS 7 - Classification and Measurement of Financial Instruments

• Amendments to IFRS 9 and IFRS 7 - Contracts Referencing Nature-dependent Electricity

• Annual improvements (Volume 11) - Amendments to various IFRS standards with the primary goal to improve the clarity and internal consistency

NEW STANDARD IFRS 18 - PRESENTATION AND DISCLOSURE IN FINANCIAL STATEMENTS (APPLICABLE AS OF JANUARY 1, 2027)

IFRS 18 replaces IAS 1 Presentation of Financial Statements. This standard sets out new requirements for the presentation and disclosure of information, but it will not affect the recognition or measurement of items in the financial statements. It will be required to classify income and expenses in the following five categories: operating, investing, financing, discontinued operations, and income tax. It is required to present the new subtotal "profit or loss before financing and income taxes". Companies are required to start the cash flow statement from the operating profit subtotal when presenting cash flows from operating activities using the indirect method. The new standard establishes the term Management Performance Measures (MPMs) and sets out the related disclosure requirements. The standard is required to be applied retrospectively.

Presentational changes. Upon the adoption of IFRS 18, the Group will make presentational changes to the income statement. The main impact on the Group's operating profit compared to the currently applied presentation will come from foreign exchange gains/losses on internal financing and gains/losses on the net monetary position in hyperinflationary economies. These are currently included in 'Other financial expenses and net result on foreign exchange' and will be reclassified into the operating result. In the first six months of 2026, the combined effect was immaterial. These presentational changes have no impact on sales, net income, or earnings per share of the Group as a whole.

Transition. The Group will apply the full retrospective method for the transition. This means that the comparative 2026 results will be restated when the new standard is applied in 2027.

Acquisitions in 2025

In the first half of 2025 Sika acquired Elmich Pte. Ltd., Singapore, Cromar Building Products Limited, UK, HPS North America, Inc., USA, and Gulf Additive Factory LLC (GAF), Qatar. The purchase price allocation (PPA) of GAF was revised to increase provisions by CHF 0.6 million, with a corresponding adjustment to goodwill, thus appropriately reflecting risks related to product claims. The purchase prices and purchase price allocations of all other acquisitions remained unchanged and are now final.

Acquisitions in 2026

On February 2, 2026, Sika acquired Finja, a leading Swedish manufacturer of a wide range of mortars and integrated solutions that enhance efficiency and sustainability in construction. The acquisition will strengthen Sika's Nordic presence and provide major cross-selling opportunities through the highly complementary product portfolios and increased presence in the distribution channel. In addition, it will enable substantial capacity expansion, supporting future growth by bringing a wider product offering closer to Nordic customers.

Since the purchase, Finja has contributed sales of CHF 30.1 million. The result was below materiality level.

On February 13, 2026, Sika announced that it had reached an agreement to acquire Akkim, a leading global manufacturer of adhesives and sealants based in Turkey. This acquisition will strengthen Sika's position in the global adhesives and sealants industry and unlock substantial growth opportunities through expanded presence in the distribution channel and broader geographic reach, namely in the high-growth markets in Eastern Europe, Central Asia, the Middle East, and North Africa. Akkim will add considerable production capacity, enabling a more efficient operational footprint. With its large product portfolio, the company covers a wide range of adhesive and sealant applications and technologies for the construction sector. The offering is based on proprietary formulations developed by a strong R&D team. The company generated net sales of approximately CHF 220 million in 2025. The closing of the acquisition is subject to regulatory approval and is expected to occur in the third quarter of 2026.

ACQUIRED NET ASSETS AT FAIR VALUES

in CHF mn Finja

If the acquisition had occurred on January 1, 2026, consolidated pro-forma net sales would have been CHF 5,593.2 million (+CHF 3.4 million).

Since the purchase prices and the purchase price allocations still entail some uncertainty, all positions are provisional. Market access and combined distribution channels and supplementary product portfolios justify the goodwill posted.

The directly attributable transaction cost of the acquisition amounted to CHF 0.7 million and were charged to other operating expenses.
