Foreword of the CEO

img-11.jpeg

"Our stable operational performance shows that the consistent focus on high-margin specialty applications and technologically demanding niche markets is paying off even in a challenging environment."

img-12.jpeg

"The improved incoming orders at the start of the year give us confidence that we will regain momentum over the course of the year and achieve our growth targets."

"The demand impulses from markets such as AI infrastructure, thermal management, and battery cell applications in electric mobility confirm Nabaltec's strategic focus on future-oriented applications with long-term growth potential."

FOREWORD

of the CEO

Ladies and Gentlemen,

Dear Shareholders and Business Partners,

In the first quarter of 2026, demand remained subdued due to the challenging market environment and weak economic conditions. However, positive signs are increasing that Nabaltec will return to a growth trajectory starting in the second quarter of 2026 and over the further course of the year.

At the beginning of the year, the chemical-pharmaceutical industry recorded a declining trend, particularly in international business, and was unable to participate in the growth seen in other regions of the world. Structural challenges to Germany's competitiveness as a business location had a negative impact, including high energy prices, increasing regulatory requirements, and lengthy approval procedures. In addition, geopolitical developments and trade policy uncertainties created further pressure on the markets. Despite the challenging market conditions, we succeeded in generating revenues of EUR 53.2 million in the first quarter of 2026 and limiting the decline compared to the same quarter of the previous year to 2.7%.

Stability in the core business despite a weak market environment

Overall, the two product segments "Functional Fillers" and "Specialty Aluminas" continue to prove resilient and support the company even in a challenging environment. Nabaltec's reliable foundation is built on a clear focus on select niche markets in the specialty chemicals sector, a balanced product mix, and a strong commitment to meeting our customers' needs. These factors enable the company to maintain stability and continue to perform solidly in the market even under difficult conditions, although certain areas are currently more affected by demand fluctuations than others.

NABALTEC AG


TO OUR SHAREHOLDERS
Foreword of the CEO

Further information on Nabaltec AG's global growth markets can be found at www.nabaltec.de/en/company/we-at-nabaltec

With operating profit of EUR 2.7 million, we also achieved an EBIT margin (EBIT as a percentage of total performance) of 5.2% in the first quarter of 2026 and therefore remained within the target range of 5% to 7% for the full year. Operating cash flow of EUR 13.2 million also underscores Nabaltec's continued robust operating base and solid ability to finance operations internally.

Innovation-driven growth opportunities and technology fields

At the same time, innovations in new product ranges are opening up important opportunities for renewed growth. In 2026, our viscosity optimized hydrates are a particular focus, as they are developing dynamically, especially in Europe and the United States. With these additives, Nabaltec primarily supports applications in the thermal management of lithium-ion batteries.

In addition, our fine hydroxides and boehmites are highly advanced products that, due to their outstanding product characteristics, are indispensable for cable applications used in AI infrastructure data centers, in batteries for e-mobility and power electronics, as well as in the production of renewable energy. These materials make a decisive contribution to the safety and performance of modern technologies and enable innovative solutions for demanding applications.

Despite their outstanding product characteristics, development in the boehmites product range continues to remain subdued. Demand is closely linked to the expansion of European battery cell manufacturing capacity, which is currently progressing more slowly than expected. From a long-term perspective, we continue to see significant growth potential, as boehmite remains a key material for modern battery technologies.

Confident outlook for Financial Year 2026

Overall, demand trends are showing increasing signs of stabilization, which is also reflected in incoming orders. By the end of the first quarter of 2026, these had already exceeded the level from the previous year and recovered significantly, particularly compared to the weaker final quarter of the previous year. This represents a positive indication for further business development over the course of the year.

Despite an economic environment that continues to be characterized by uncertainty, we remain confident regarding Financial Year 2026 and expect a return to a growth trajectory, combined with revenue growth of 4% to 6%. This development is supported by structural growth drivers such as rising demand for fire protection solutions and the increasing need for secure cable systems in connection with the expansion of data centers. Additional momentum is expected from e-mobility and the energy storage solutions sector.

[Improved momentum
based on of the
second quarter of 2026]

At present, we already expect improved momentum starting in the second quarter of 2026, which should provide additional impetus over the further course of the year. Despite the continuing challenging environment, we therefore see Nabaltec on a stable path to consistently continue its strategic development and sustainably capitalize on emerging growth opportunities.

CONSOLIDATED INTERIM MANAGEMENT REPORT

as of 31 March 2026

Course of business

In the first three months of 2026, Nabaltec AG generated consolidated revenues of TEUR 53,209, compared with TEUR 54,707 in the same period of the previous year. This corresponds to a revenue decline of 2.7% in the three-month period. Overall, business development did not meet the original expectations for the first quarter but nevertheless remained comparatively stable against the backdrop of the current economic environment: The outbreak of the Iran war led to significant deterioration within the chemical industry in the first quarter of 2026 and slowed the anticipated recovery overall.

In the "Functional Fillers" product segment, Nabaltec generated quarterly revenue of TEUR 39,429, compared to TEUR 40,269 in the first quarter of 2025. This corresponds to a revenue decline of 2.1%. In the viscosity optimized hydrates product range, Nabaltec once again achieved strong growth in the first quarter of 2026, increasing revenue by 28.0% compared to the same quarter of the previous year. Sales volumes in the boehmites product range declined slightly during the reporting quarter.

The "Specialty Aluminas" product segment generated revenues of TEUR 13,780 in the first three months of 2026, representing a decline of 4.6% compared with revenues of TEUR 14,438 in the same period of the previous year. Weak steel demand continues to weigh on the refractory market.

Nabaltec generated earnings before interest, taxes, depreciation, and amortization (EBITDA) of TEUR 6,365 in the first quarter of 2026, compared with TEUR 6,980 in the corresponding period of the previous year (-8.8%). The EBITDA margin (EBITDA as a percentage of total performance) amounted to 12.2%, compared to 12.6% in the same period of the previous year.

INTERIM REPORT 1/2026


CONSOLIDATED INTERIM MANAGEMENT REPORT

Course of business

EBIT at TEUR 2,732
EBIT margin at 5.2%

In the first three months of 2026, operating profit (EBIT) amounted to TEUR 2,732, compared to TEUR 4,129 in the corresponding period of the previous year (-33.8%). The EBIT margin (EBIT as a percentage of total performance) stood at 5.2% (Q1/2025: 7.5%) and was primarily burdened by high energy costs as well as scheduled higher depreciation and amortization.

Facilities per share of EUR 0.20

The net financial income amounted to TEUR -569 in the first quarter of 2026, compared with TEUR -495 in the same comparison period.

In the reporting period 2026, Nabaltec AG generated earnings before taxes (EBT) of TEUR 2,163, compared to TEUR 3,634 in the same quarter of the previous year. After taxes, consolidated result for the period amounted to TEUR 1,803, compared to TEUR 2,763 in the corresponding quarter of the previous year. Earnings per share therefore amounted to EUR 0.20 for the first quarter of 2026 (previous year: EUR 0.31).

Nabaltec's total performance declined from TEUR 55,339 in the same period of the previous year to TEUR 52,310 in the first three months 2026. Compared with the corresponding previous year period, which recorded a slight increase in inventories of finished and unfinished goods of TEUR 246, the first quarter of 2026 saw a significant inventory reduction of TEUR 1,105.

Compared to the corresponding period of the previous year, cost of materials decreased to TEUR 26,606 in the first quarter of 2026 (Q1/2025: TEUR 28,807). The cost of materials ratio (cost of materials as a percentage of total performance) amounted to 50.9% in the first three months of 2026, compared to 52.1% in the corresponding period from the previous year, and therefore remained slightly above expectations despite the improvement. High energy costs in particular had an impact in the first quarter of 2026. The gross profit margin (gross profit as a percentage of total performance) amounted to 50.4% in the reporting quarter and therefore increased slightly compared to the first quarter of the previous year (49.4%). With a headcount of 510 employees (31 March 2025: 501 employees), personnel expenses amounted to TEUR 10,521 in the first quarter of 2026, compared to TEUR 10,367 in the corresponding period of the previous year. The personnel expense ratio (personnel expenses as a percentage of total performance) increased from 18.7% to 20.1%. Depreciation and amortization at Nabaltec amounted to TEUR 3,633 in the first quarter of 2026, significantly above the figure of TEUR 2,851 recorded in the corresponding period from the previous year, in line with planning and reflecting the recently completed investment projects.

Other operating expenses declined from TEUR 10,013 in the corresponding quarter to TEUR 9,480 in the first three months of 2026. These primarily include freight costs, selling costs and third-party services for repairs, among other things. In addition, currency losses of TEUR 324 were recorded in the first three months of 2026. The ratio of other operating expenses (other operating expenses as a percentage of total performance) remained unchanged from the previous year at 18.1%.

INTERIM REPORT 1/2026

NABALTEC AG


CONSOLIDATED INTERIM MANAGEMENT REPORT

Course of business

Nabaltec's export ratio amounted to 71.9% in the first three months of 2026 and was therefore significantly below the level of 78.3% recorded in the same period from the previous year, while still remaining at a high level. Overall, the chemical-pharmaceutical industry recorded a significant decline in international business at the beginning of the year. From a regional perspective, relative revenue shares in the first three months of 2026 declined significantly in Europe (not including Germany), while increasing in all other regions.

After the first three months of 2026, cash flow from operating activities amounted to TEUR 13,191, compared to TEUR 12,889 in the first quarter of the previous year. Changes in working capital had a positive effect in this regard: compared to the corresponding period from the previous year, inventories in particular declined much more significantly.

Compared to the corresponding period from the previous year, in which cash outflow for investments amounted to TEUR 5,471, the liquidation of fixed-term deposits with a maturity of more than three months in the amount of TEUR 15,000 resulted in a cash inflow from investing activities of TEUR 6,099. Excluding this effect, investments increased compared to the corresponding quarter of the previous year. Cash outflows for investments in fixed assets amounted to TEUR 8,904 and were attributable to technical equipment and machinery for the expansion of capacities in the viscosity optimized hydrates product range, as well as to replacement investments, digitization projects, and process optimization at the Schwandorf site. As a result, free cash flow in the first quarter of 2026 amounted to TEUR 19,290, compared to TEUR 7,418 in the corresponding three-month period of the previous year.

In the Nabaltec Group, cash and cash equivalents amounted to TEUR 91,957 as of 31 March 2026, compared to TEUR 93,678 in the corresponding quarter of the previous year.

Total assets increased from TEUR 300,709 as of 31 December 2025 to TEUR 311,719 (+3.7%). Non-current assets increased by 7.0% as of the reporting date of 31 March 2026 to TEUR 162,998 (31 December 2025: TEUR 152,393). Current assets increased slightly by 0.3% to TEUR 148,721 (31 December 2025: TEUR 148,316).

With an equity ratio of 51.6%, Nabaltec's equity capitalization represents a very solid basis compared to the rest of the industry. Non-current liabilities amounted to TEUR 128,176 as of 31 March 2026, 3.8% above the level at year-end 2025 (31 December 2025: TEUR 123,519). This increase was attributable to lease liabilities in connection with the commissioning of the new logistics hub at Rhenus Weserport GmbH in Bremen in January 2026. Current liabilities increased from TEUR 18,906 at year-end 2025 to TEUR 22,789.

Employees / Outlook

Employees

Total number of employees at 510 training rate at 7.6%

As of 31 March 2026, the Nabaltec Group employed 510 people (including trainees), compared to 501 employees at the corresponding reporting date of the previous year. Of these, 493 employees were based in Germany. The training ratio amounted to 7.6%, unchanged from the reporting date of the previous-year quarter.

Outlook

Incoming orders to TEUR 66,260

At the beginning of 2026, demand continued to be characterized by short-term ordering patterns. The company does not expect any significant improvement in the foreseeable future; however, for the majority of product ranges, it generally anticipates largely stable demand for the current Financial Year. A positive indication in this regard is provided by incoming orders, which increased to TEUR 66,260 in the first quarter of 2026 and therefore exceeded the figures recorded in each of the four quarters of the previous year.

In the US, Nabaltec expects business to remain good at Nashtec LLC and to continue to improve successively at Naprotec LLC.

In 2026 as well, fine hydroxides will continue to be the most important product range by far within the "Functional Fillers" product segment. In addition, the viscosity optimized hydrates product range is becoming increasingly important. Development in the boehmites product range for e-mobility recently stagnated significantly, as the expansion of battery cell production capacities in Europe and the structural transformation of the automotive industry toward European value creation continue to progress more slowly than expected.

In the "Specialty Aluminas" product segment, weak demand for products used in the refractory industry continues to weigh on development. However, a slight turnaround appears to be emerging after business declined over the past two years.

Confirmation of forecast:
Revenue growth in the
impact of the 2026
EBIT margin on the value
of 5% to 7%

Nabaltec confirms the forecast for Financial Year 2026 presented in the consolidated management report 2025 and, despite the challenging macroeconomic and industry-specific environment, expects revenues to increase in a range of 4% to 6% for the year as a whole. Despite the slowdown during the reporting period, Nabaltec already expects a return to growth in the first half of 2026. On the earnings side, Nabaltec is expecting an EBIT margin in a range from 5% to 7%, compared to 7.7% in Financial Year 2025. The decline in the EBIT margin compared to the Financial Year 2025 results above all from increasing material expenses caused by energy prices, as well as a sharp increase in depreciation and amortization resulting from the recently completed investment projects.

INTERIM REPORT 1/2026

CONSOLIDATED INTERIM MANAGEMENT REPORT
Outlook/Report on opportunities and risks

The forecast is based on the assumption that the economy and the industries relevant to Nabaltec will develop in a stable fashion. At the time the forecast was prepared, it remains unclear at what speed or with what dynamics the economic situation will recover globally and in the markets relevant for Nabaltec.

The war in Iran has once again increased geopolitical and economic uncertainty, which could lead to growing pressure on the global economy. Rising energy prices, disrupted supply chains, potential trade barriers, inflation, high interest rates, and the overall uncertain environment are resulting in weaker consumption and investment activity worldwide. These factors may negatively affect the company's business development, particularly its liquidity, financial and earnings situation during the forecast period.

Furthermore, the other statements made in the forecast from the 2025 consolidated management report remain valid.

Report on opportunities and risks

With regard to the opportunity and risk situation presented in the 2025 consolidated management report, no significant changes were discernible in the first quarter of 2026.
