REVENUE BY BUSINESS UNITS, Q 1 2026

Outlook for 2026 (unchanged)

R E V E N U E

Kemira's revenue is expected to be between EUR 2,600 and EUR 3,000 million in 2026 (2025 revenue: EUR 2,753.5 million).

O P E R A T I V E E B I T D A

Kemira's operative EBITDA is expected to be between EUR 470 and EUR 570 million in 2026 (2025 operative EBITDA: EUR 524.6 million).

A S S U M P T I O N S B E H I N D T H E O U T L O O K ( S P E C I F I E D )

The demand in Kemira's end-markets has weakened due to continued global economic uncertainty and increased geopolitical tensions. In particular, the packaging and pulp market continues to be impacted by this uncertainty. The urban water treatment market is expected to grow modestly, but there is demand volatility within Kemira's industrial customer segment. The outlook assumes that Kemira can largely mitigate raw material and logistics cost increases caused by the war in Iran. The outlook assumes no major disruptions to Kemira's manufacturing operations or the supply chain and for the US dollar to weaken slightly from the end of 2025. The acquisitions which Kemira announced before the Financial Statements Bulletin 2025 was published are included in the outlook.

The continued global economic uncertainty has resulted in softer volume demand in Kemira's end-markets. The uncertainty is impacting the packaging and pulp market in particular, while the water treatment market is expected to grow, although there is volatility caused by the economic uncertainty among Kemira's industrial customers. The outlook assumes a stable raw material environment, no major disruptions to Kemira's manufacturing operations or the supply

chain and for the US dollar to weaken slightly from the end of 2025. The acquisitions which Kemira has announced prior to publishing the Financial Statements Bulletin 2025 are included in the outlook.

Kemira's President & CEO, Antti Salminen:

"Kemira's Q1 was challenging. The market environment remained weak and the war in Iran increased uncertainty and accelerated inflation. As a result, both our revenue and profitability decreased year-on-year. While the market volatility is expected to continue, we are taking measures to mitigate the impacts of the demand softness and the increased cost base, to get our profitability back on track and in line with our target range.

In Q1, Kemira's operating environment was impacted by the intensified geopolitical tensions. Our demand environment was already challenging prior to the start of the war in Iran, which has only further increased market volatility.

Following the slow demand and the negative FX impact, Kemira's Q1 revenue decreased year-on-year. Consequently, the operative EBITDA margin declined to 17.3%. Sequentially, sales volumes and prices increased.

In Water Solutions, revenue remained close to the previous year's level. However, the operative EBITDA margin declined to 18.4%, mainly driven by pricing and higher costs, including a couple of one-off like items. In Packaging & Hygiene Solutions, revenue decreased year-on-year. The operative EBITDA margin decreased to 10.1%, primarily driven by pricing. The implementation of the new operating model is progressing according to our plans. In Fiber Essentials, revenue decreased year-on-year and yet increased sequentially. The operative EBITDA margin improved to 26.7%, following favorable pricing development.

We continued to make progress with our strategy execution in Q1. At the beginning of the year we announced the first follow-up deal in industrial water treatment services, when we completed the acquisition of AquaBlue, Inc. In February, we announced the acquisition of SIDRA Wasserchemie, expanding our core coagulant business in Western and Central Europe. The acquisition is currently being reviewed by the competition authorities in Germany. We also announced our plan to build an activated carbon reactivation site in Tarragona, in Spain.

Looking ahead, at the moment we do not see any major changes in the market environment in the near-term, except for the usual revenue seasonality. We reiterate our financial outlook for

this year and expect our 2026 revenue to be between EUR 2,600 million and EUR 3,000 million and our 2026 operative EBITDA to be between EUR 470 million and EUR 570 million.

To mitigate the impact of increased costs, we have implemented price increases. Historically, it has usually taken up to two quarters before these have become visible in our financials, due to customer contract terms. In addition, we will continue to drive efficiency improvements throughout the company and need to examine all facets of our business to ensure that our cost base is aligned with the uncertain demand environment. Our profitability was disappointing in Q1 and our aim is to attain our operative EBITDA margin target range of

18-21% again on a quarterly basis.

Although the long-term demand drivers for our business remain unchanged, we are facing headwinds at the moment. While we remain committed to executing our strategy and investing in long-term growth, it is clear that more focus is needed on ensuring our competitiveness in a volatile and soft market."

‌KEY FIGURES AND RATIOS

*12-month rolling average

Unless otherwise stated, all comparisons in this report are made to the corresponding period in 2025.

Kemira provides certain financial performance measures (alternative performance measures) that are not defined by IFRS. Kemira believes that alternative performance measures followed by capital markets and by Kemira management, such as revenue growth in local currencies, excluding acquisitions and divestments (=organic growth), EBITDA, operative EBITDA, operative EBIT, cash flow after investing activities and gearing provide useful information on Kemira's comparable business performance and financial position. Selected alternative performance measures are also used as performance criteria in remuneration.

Kemira's alternative performance measures should not be viewed in isolation from the equivalent IFRS measures and alternative performance measures should be read in conjunction with the most directly comparable IFRS measures. Definitions of the alternative performance measures can be found in the definitions of the key figures in this report, as well as at https://www.kemira.com > Investors > Financial information. All the figures in this report have been individually rounded and consequently the sum of the individual figures may deviate slightly from the total figure presented.

‌Short-term risks and uncertainties

Global economic uncertainty has continued during the first quarter of 2026, following the start of the war in Iran and other geopolitical tensions as well as the continued threat of a global trade war.

The major impact on Kemira from the war in Iran is expected to come from price increases for oil-based raw materials. Kemira has announced customer price increases to mitigate the impact of increasing raw material and logistics costs. There is usually a delay of up to two quarters before the effects of the price increases will become visible in our financial reporting. The indirect impacts of the crisis on customer demand depend on the duration and on the extent of the crisis, factors which are very difficult to predict.

A detailed description of Kemira's risk management principles is available on the company's website, at kemira.com > investors >Risks and uncertainties. Financial risks are described in the Notes to the Financial Statements for the year 2025.

Acquisitions and divestments

On February 11, 2026, Kemira announced that it will strengthen its Water Solutions business in Europe by acquiring SIDRA Wasserchemie. The acquisition is subject to merger clearance by the Federal Cartel Office in Germany and is expected to close during the second half of this year. The purchase price is approximately EUR 75 million, subject to usual purchase price adjustments.

On January 9, 2026, Kemira announced that it had completed the acquisition of AquaBlue, Inc., a privately-owned company based in the US. The deal, valued at under USD 10 million, strengthens Kemira's position in North America and supports its growth in industrial water treatment services - a sector growing faster than traditional water treatment markets.

Other important announcements during the review period

On March 13, 2026, Kemira will be implementing price adjustments globally as a result of the evolving situation in the Middle East and its impact on global supply chains, raw material markets, transportation and pricing.

On March 4, 2026, Kemira has conveyed a total of 314,703 treasury shares without consideration to 70 key employees participating in the performance period 2023-2025 of the Performance Share Plan 2022-2026.

On February 17, 2026, Kemira plans to expand its Tarragona manufacturing site in Spain by building an activated carbon reactivation plant. The pre-engineering phase of the project is currently starting and the new plant is expected to be operational at the end of 2029, depending on the timeline of the final investment decision and the process for acquiring environmental permits. The total value of the investment is expected to be around EUR 20 million.

‌Events after the review period

No significant events after the review period.

Outlook for 2026 (unchanged)

R E V E N U E

Kemira's revenue is expected to be between EUR 2,600 and EUR 3,000 million in 2026 (2025 revenue: EUR 2,753.5 million).

O P E R A T I V E E B I T D A

Kemira's operative EBITDA is expected to be between EUR 470 and EUR 570 million in 2026 (2025 operative EBITDA: EUR 524.6 million).

A S S U M P T I O N S B E H I N D T H E O U T L O O K ( S P E C I F I E D )

The demand in Kemira's end-markets has weakened due to continued global economic uncertainty and increased geopolitical tensions. In particular, the packaging and pulp market continues to be impacted by this uncertainty. The urban water treatment market is expected to grow modestly, but there is demand volatility within Kemira's industrial customer segment. The outlook assumes that Kemira can largely mitigate raw material and logistics cost increases caused by the war in Iran. The outlook assumes no major disruptions to Kemira's manufacturing operations or the supply chain and for the US dollar to weaken slightly from the end of 2025. The acquisitions which Kemira announced before the Financial Statements Bulletin 2025 was published are included in the outlook.

P R E V I O U S A S S U M P T I O N S B E H I N D T H E O U T L O O K ( P U B L I S H E D O N F E B R U A R Y 1 3 , 2 0 2 6 )

‌The continued global economic uncertainty has resulted in softer volume demand in Kemira's end-markets. The uncertainty is impacting the packaging and pulp market in particular, while the water treatment market is expected to grow, although there is volatility caused by the economic uncertainty among Kemira's industrial customers. The outlook assumes a stable raw material environment, no major disruptions to Kemira's manufacturing operations or the supply chain and for the US dollar to weaken slightly from the end of 2025. The acquisitions which Kemira has announced prior to publishing the Financial Statements Bulletin 2025 are included in the outlook.

Financial targets

Kemira has the following long-term financial targets to support its growth strategy; Kemira's target is to achieve an annual organic growth rate of over 4%, to maintain an operative EBITDA margin within the range of 18-21% and to maintain operative ROCE above 16%.

The maximum number of shares to be repurchased is 5,000,000, and the maximum monetary amount to be used for the program is EUR 100 million. The repurchases will be carried out between February 13, 2026, and September 20, 2026. Repurchased shares will be cancelled after the program has ended.

   Kemira had in its possession 2,510,789 treasury shares on March 31, 2026. The average share price of treasury shares was EUR 16.82 and they represented 1.7% of the share capital and the aggregate number of votes conferred by all shares. The aggregate par value of the treasury shares is EUR 3.7 million.

   The share premium is a reserve accumulated through subscriptions and entitlements through the management stock option program 2001.

The fair value reserve is a reserve accumulating based on other shares measured at fair value and hedge accounting. Other reserves originate from the local requirements of subsidiaries. The unrestricted equity reserve includes other equity-type investments and the subscription price of shares to the extent that they will not, based on a specific decision, be recognized in share capital.

‌Group key figures

Kemira provides certain financial performance measures (alternative performance measures) that are not defined by IFRS. Kemira believes that alternative performance measures followed by capital markets and Kemira management, such as revenue growth in local currencies, excluding acquisitions and divestments (=organic growth), EBITDA, operative EBITDA, operative EBIT, cash flow after investing activities and gearing provide useful information about Kemira's comparable business performance and financial position. Selected alternative performance measures are also used as performance criteria in remuneration.

Kemira's alternative performance measures should not be viewed in isolation from the equivalent IFRS measures and alternative performance measures should instead be read in conjunction with the most directly comparable IFRS measures. Definitions of the alternative performance measures can be found in the definitions of the key figures in this report, as well as at https://www.kemira.com > Investors > Financial information.

1. 12-month rolling average
