Liam Condon, Chief Executive Officer, commented:
Following the agreement to sell Catalyst Technologies, we are transforming Johnson Matthey into a more highly focused, lean and cash generative business. Our focus on increased efficiency has driven a strong first half performance with significant growth in pro forma underlying operating profit¹. We are also making good progress in implementing our cash-focused business model, with the benefits starting to come through and a material step up in free cash flow expected for the full year². The carve out of Catalyst Technologies is progressing well and we remain on track to complete the transaction by the first half of calendar year 2026.
For the full year, we expect to deliver growth in underlying operating profit at the higher end of a mid single digit percentage range⁵,¹¹. Looking ahead, with momentum building in efficiency and cash generation, we are on track to achieve our medium-term targets and deliver materially enhanced shareholder returns.
Unchanged group outlook for the year ending 31st March 2026⁴
For 2025/26, we expect to deliver underlying operating profit growth at the higher end of a mid single digit percentage range,despite the challenging macroeconomic environment.This is on a
pro forma basis, excluding Catalyst Technologies and Value Businesses, and at constant precious metal prices and constant currency.⁵ Overall performance will continue to be weighted towards the second half. However,second half performance will be lower year-on-year driven by PGM Services, reflecting lower metal recoveries and refining volumes, as expected.
In Clean Air we expect modest growth in operating profit, with a margin of 14 to 15%. This is based on external data which suggest a 5% decline in global light duty vehicle production for 2025/26. Operating profit growth and margin expansion will be driven by our ongoing operational excellence and transformation benefits. In PGM Services, we expect lower operating profit largely reflecting reduced metal recoveries. In Hydrogen Technologies, we continue to expect to achieve operating profit breakeven by the end of 2025/26.¹¹
If PGM (platinum group metal) prices remain at their current level¹² for the remainder of 2025/26, we expect a c.£20 million benefit to full year operating profit compared with the prior year.¹³
At current foreign exchange rates¹⁴, translational foreign exchange movements for the year ending 31st March 2026 are expected to have a limited effect on underlying operating profit.
Over the medium-term to 2027/28, we continue to expect at least mid single digit CAGR in
pro forma operating profit.⁵
Dividend
The board has approved an interim dividend of 22.0 pence per share, maintained at the same level as the prior year (1H 2024/25: 22.0 pence per share). The interim dividend will be paid on
3rd February 2026, with an ex-dividend date of 27th November 2025, to shareholders on the register at the close of business on 28th November 2025.
Board and Group Leadership Team changes
On 17th July 2025, we announced the appointment of Andrew Cosslett as Non-Executive Chair of the Board. He is also a member and Chair of the Nomination Committee and member of the Societal Value Committee. Andrew is an experienced Chair with a strong track record in leading significant transformational and cultural change, to help deliver long-term shareholder value. He is currently Chair of ITV plc and has held a number of senior executive and non-executive roles across a range of sectors. Andrew succeeds Patrick Thomas who stepped down from the Board at the end of the 2025 Annual General Meeting in July.
As JM transitions into a more highly focused and lean business, we have further streamlined our Group Leadership Team from nine to six people. These changes, which will support the focused implementation of JM's strategy, are effective from 1st January 2026.
Alastair Judge, currently Head of Strategy and Operations, has been appointed Chief Financial Officer and member of the Board. Richard Pike, JM's current Chief Financial Officer and Chief Executive of PGM Services - having assumed responsibility of PGM Services in August 2025 - will assume the role of Chief Operating Officer and will remain on the Board. These organisational changes will further strengthen our ability to deliver on our strategy, drive cash generation and increase shareholder returns.
Anish Taneja, Chief Executive of Clean Air and Hydrogen Technologies, has decided to leave Johnson Matthey to take up an external position, based in Germany. Anish joined JM in 2022 and has successfully strengthened Clean Air, leaving the business well positioned to deliver on its strategy.

Strategic update
Following the agreed sale of Catalyst Technologies to Honeywell International Inc. (Honeywell), we are re-shaping JM intoa more highly focused, lean and cash generative business. Through leveraging our leading market positions in Clean Air and PGM Services, and driving efficiencies across the group, we expect to deliver a step change in cash generation and materially enhanced shareholder returns.
Driving a step change in cash generation
We are implementing acash-focused business model, incorporating ongoing actions across three key areas: overhead reduction, materially lower capex and improved working capital management. These priorities are reflected in our executive remuneration schemes, with 37.5% of the annual bonus now linked to free cash flow, 37.5% based on underlying profit before tax and the remaining 25% based on strategic targets.
As we drive efficiencies, in the first half we streamlined our support functions including Finance, IT, HR and Procurement, and reduced our corporate headcountby around 10%. Construction of our new PGM refinery is progressing and, when this is complete, we expect group capex to reduce materially to c.£120 million per annum by 2027/28, below depreciation and amortisation. We have identified opportunities to reduce total working capital by c.£250 million by 2027/28, with progress in the period including improving supplier payment terms and optimising the frequency of payment runs. Our focus on reducing overheads and capex, and improved working capital management will enable us to generate annualised sustainable free cash flow of at least £250 million by 2027/28.
Committed to materially enhanced shareholder returns
We have a disciplined capital allocation policy which will delivermaterially enhanced shareholder returns,whilst maintaining a strong balance sheet following completion of the Catalyst Technologies disposal. We are targeting net debt to EBITDA of 1.0 to 1.5 times. Our priorities for use of capital are:
1.Organic investment - focused on maintenance and operational improvement after the completion of our new PGM refinery
2.Shareholder returns - growing annual cash returns to shareholders from at least £130 million for 2025/26 (ordinary dividend) to at least £200 million for 2026/27 and beyond (split between ordinary dividends and share buybacks)
3.Bolt-on acquisitions only considered for highly compelling opportunities in core areas
Clean Air - a leading global player driving material margin improvement
In Clean Air, we aim to be a lasting partner providing world-leading technology to support our customers and reduce harmful emissions.
We are focused on maintaining our leading position in diesel, securing a profitable share in gasoline including hybrids, and driving continued margin improvement.In the half, wewon new gasoline hybrid business with leading Chinese OEMs.We will also benefit from longer-term growth in our Clean Air Solutions business by applying our leading technology to emerging emissions control applications such as hydrogen internal combustion engines, backup generators for data centres and CO2 capture.For example, we recently signed multi-year contracts for emissionscontroltechnologyfor data centre applications.
 
In the first half, we delivered an operating margin improvement of 200 basis points, to 12.4%. We reduced headcount by c.10%, primarily across R&D and manufacturing. R&D and SG&A spend is on track to reduce by c.20% by the end of 2025/26. We also made further progress consolidating our manufacturing footprint, closing an additional production line in India. Overall, we now have 11 plants and 21 lines (2021/22: 16 plants, 50 lines).
Underpinned by benefits from these initiatives, as well as ongoing operational and commercial excellence, we are targeting operating margin improvement to 14 to 15% for full year 2025/26. Alongside driving efficiency, we have been focused on employee engagement, which has continued to increase despite the extensive transformation that is ongoing across our Clean Air business.
Longer-term, we remain on track to deliver Clean Air sales of more than £2 billion (of which c.90% of the business is already won) and an operating margin of 16 to 18% in 2027/28. Additionally, we expect Clean Air to generate at least £2.1 billion of further cash by 2030/31¹, with significant cash flow beyond.
PGM Services - a world leader in PGMs
PGM Services is the world's largest secondary refiner of PGMs (by volume), the global liquidity hub for PGMs² and expert in converting PGMs into high value products for a wide range of industries.
We are investing in a new world-class PGM refinery to replace our aged UK asset. This investment will support increasing demand for secondary (recycled) metal, as well as deliver significant efficiency, resilience, safety and sustainability benefits. We expect to start commissioning the facility in the second half of fiscal year 2025/26, and be operational in calendar year 2027.
In PGM Products, we continue to expect growth in new, high value PGM applications for a wide range of industries such as agrochemicals, pharmaceuticals and defence.
Over the next couple of years, until our new PGM refinery is fully operational, we expect increased maintenance costs relating to our current aged refinery, as well as lower metal recoveries. In addition, we will incur dual-running costs and higher depreciation costs from 2027 onwards as the new refinery comes online, before returning to growth in 2027/28. In 2027/28, we expect PGM Services to generate sales of around £450 million, with an operating margin of around 30%³. Beyond this, underpinned by our new refinery and growth in PGM Products, we expect PGM Services to deliver at least low single digit CAGR in underlying operating profit over the medium to long-term.
Hydrogen Technologies - a leader in fuel cell and electrolyser components
Hydrogen Technologies is well-positioned in the green hydrogen market. Reflecting the market slowdown we have restructured the business to reduce costs, whilst maintaining long-term growth optionality. We continue to expect Hydrogen Technologies to reach operating profit breakeven by the end of 2025/26 and be cash flow positive in 2026/27⁴.
Notes:
1.Delivered £2.4 billion of cash cumulatively from 1st April 2021 to 31st March 2025. Cash target of at least £4.5 billion from 1st April 2021 to 31st March 2031, pre-tax and post restructuring costs.
2.Global liquidity hub for PGM sponge (powder).
3.Assumes broadly constant PGM prices.
4.Cash flow defined as underlying operating profit plus depreciation and amortisation (EBITDA), less capital expenditure and net working capital movements.
   
Sale of Catalyst Technologies
As announced on 22nd May 2025, we have agreed the sale of Catalyst Technologies to Honeywell for an enterprise value of £1.8 billion on a cash and debt-free basis. The carve out of Catalyst Technologies is progressing well and we have received the vast majority of competition authority approvals. We continue to expect completion by the first half of calendar year 2026.
Following completion, we intend to return £1.4 billion of net proceeds to shareholders -
£1.15 billion via a special dividend with a share consolidation, and the remaining £250 million via an on-market share buyback programme.
What JM will deliver by 2027/28
JM will become a highly streamlined group, delivering a step change in cash generation and materially enhanced shareholder returns. By 2027/28 we expect:
·At least mid single digit CAGR in pro forma underlying operating profit (2024/25 baseline¹)
·Annualised sustainable free cash flow of at least £250 million driven by cost savings, lower capex and improved working capital management
·Cash returns of at least £200 million per annum to shareholders

Performance summary for the six months ended 30th September 2025¹
Pro forma underlying operating profit² - excluding the impact of PGM prices - grew 29% in the period. Our performance was supported by self-help actions including cost efficiencies across the group. Average PGM prices increased in the half, with a benefit to underlying operating profit of £10 million. Including the impact of PGM prices, pro forma underlying operating profit² grew 38%.
Clean Air underlying operating profit grew 11% and margin expanded 200 basis points to 12.4%, driven by efficiency benefits. These included reduced R&D and SG&A overheads in the business, as well as benefits from operational excellence and footprint consolidation. PGM Services delivered a strong first half with underlying operating profit up 33%, driven by higher average PGM prices, strong performance in our PGM trading business and efficiencies. Hydrogen Technologies delivered a smaller operating loss of £18 million reflecting benefits from cost control actions taken in 2024/25 as we restructured the business and reduced headcount.
On a reported basis, operating profit decreased to £117 million (1H 2024/25: £527 million³). The decline largely reflected a £484 million profit on disposal recognised in the prior year, principally related to Medical Device Components. We incurred £33 million of major impairment and restructuring charges, comprising restructuring charges of £26 million and an impairment charge of £7 million.
Net debt (continuing) increased to £971 million as at 30th September 2025 compared to
£810 million as at 31st March 2025. Net debt to EBITDA was 2.0 times (31st March 2025:
1.8 times). Free cash flow⁴ was a £4 million inflow, a significant improvement from a£165 million outflow in the first of half of 2024/25.This was driven by higher profit and improved working capital management in Clean Air and PGM Services.

Clean Air provides catalysts for emission control after-treatment systems used in light and heavy duty vehicles powered by internal combustion engines.
Market commentary
In the half, global vehicle production (ICE) declined in both light duty and heavy duty. In light duty, there were modest declines across all key regions. European and North American production was impacted by tariff uncertainty, and there was further battery electric vehicle penetration in Europe and China.
In heavy duty, ICE vehicle production grew well in Europe, whilst Asia was flat and North America saw a material decline. In Europe growth reflected cyclical recovery, whilst in Asia, growth in India was offset by a decline in China. In North America, both Class 8 and
Class 4 to 7 truck production declined driven by the effect of tariffs and uncertainty around the timing and final requirements of EPA27 (Environmental Protection Agency) emissions legislation. Recovery of the Class 8 cycle is expected to drive higher production in 2026.
   
Performance commentary
Sales declined 7%. This mainly reflected a decline in global vehicle production driven by European light duty diesel and North American heavy duty diesel.
Sales
Light dutydiesel
In light duty diesel, sales declined 7%, underperforming a global market which saw a modest decline. In Europe, whilst sales decreased, we outperformed the market, reflecting strong performance from our largest customer. North American sales were down materially, underperforming a slightly declining market mainly due to a weaker mix. However, we saw good sales growth in Asia, due to benefits from commercial excellence as well as strong customer performance in China.
Light duty gasoline
Light duty gasoline sales were down 15%, underperforming a global market which declined slightly. By region, we saw declines in Europe and Asia, whilst sales in the Americas were broadly flat.
In Europe, we were mainly impacted by market share losses due to platform losses several years ago. In Asia, our sales decline reflected weaker platform mix in China, alongside the underperformance and phase out of some customer platforms across the rest of Asia.In the Americas, sales were broadly flat and in line with the market.
Heavy duty diesel
In heavy duty diesel, sales declined 2%, broadly in line with the global market. We experienced a decline in sales in North America, which was partly offset by good growth in Europe and Asia.
In North America, sales performance mainly reflected the decline in market production. We also experienced some customer underperformance and a weaker mix. In Europe, we outperformed a growing market mainly due to market share gains. Growth in Asia was largely driven by India, due to improved mix and the ramp up of an off-road platform.
Underlying operating profit
Underlying operating profit grew 11% and operating margin expanded 200 basis points to 12.4%, driven by efficiency benefits. These included reduced R&D and SG&A overheads in the business, as well as benefits from operational excellence and footprint consolidation.
  PGM Services  
Good sales and profit growth supported by higher PGM prices
·Sales were up 7% reflecting good growth in our refining and trading businesses as we benefitted from higher PGM prices and increased trading activity
·Underlying operating profit grew 33%, reflecting a £10 million benefit from higher average PGM prices, strong performance in our PGM trading business and efficiency benefits

Performance commentary
Sales
In the half, sales were up 7% reflecting good growth in our refining and trading businesses as we benefitted from higher PGM prices and increased trading activity. Average platinum, palladium and rhodium prices increased 27%, 11% and 30% respectively compared to the first half of 2024/25.
In our refining business sales grew well driven by higher PGM prices, although volumes were slightly down year-on-year. We saw a decline in primary volumes, which was partly offset by increased secondary (recycled) volumes due to higher industrial feeds. As we continued our asset renewal programme, we saw a small benefit from higher metal recoveries in the first half, although we continue to expect lower metal recoveries for the full year.
In our products business, sales slightly declined year-on-year, mainly driven by lower demand from pharmaceutical customers.
Underlying operating profit
Underlying operating profit grew 33% reflecting a £10 million benefit from higher average PGM prices in our refining business, strong performance in our trading business, and continued efficiency benefits including operational enhancements and streamlining processes.
 
Notes:
1.1H 2024/25 is restated to reflect the group's updated reporting segments following the agreed sale of Catalyst Technologies, where a small business outside of the sale perimeter has moved from Catalyst Technologies to PGM Services.
Hydrogen Technologies  
Smaller operating loss benefitting from cost savings
·Sales grew 15% driven by revenue recognised due to changes to volume commitments from customers in fuel cells, and higher electrolyser volumes
·Smaller operating loss of £18 million, largely reflectingbenefits from cost control actions taken in 2024/25. On track to achieve breakeven by the end of 2025/26

In Hydrogen Technologies, we provide performance-defining components across the value chain for fuel cells and electrolysers, including catalyst coated membranes (CCMs).
Performance commentary
Sales
Sales were up 15%, driven by both fuel cells and electrolysers. In fuel cells, sales benefitted from revenue recognised due to changes to volume commitments from customers. Electrolysers sales grew strongly, albeit from a small base, driven by increased demand from our strategic partners.
In the second half we expect to recognise further revenue due to changes to volume commitments from customers, in comparison with the first half.
Underlying operating loss
Underlying operating loss was £18 million, a material improvement compared to a
£26 million loss in the prior period. This largely reflected benefits from cost control actions taken in 2024/25 as we restructured the business and reduced headcount.
We continue to expect Hydrogen Technologies to reach operating profit breakeven by the end of 2025/26 and be cash flow positive in 2026/27¹.
Corporate
Corporate costs were £38 million, a decrease of £4 million from the prior period, largely reflecting lower IT and R&D costs.
         
Notes:
1.Cash flow defined as underlying operating profit plus depreciation and amortisation (EBITDA), less capital expenditure and net working capital movements.
Discontinued operations: Catalyst Technologies  
Performance impacted by weaker demand in key end markets
·Sales declined 16%, largely reflecting a weak market with reduced demand for first fill catalysts, and the timing of licence income against a strong prior period
·Underlying operating profit down 60% as a result of lower sales and weaker mix

Catalyst Technologies targets high growth, high return opportunities in fuels and chemical value chains. We have leading positions in syngas - methanol, ammonia, hydrogen and formaldehyde - and a strong sustainable technologies portfolio. Our revenue streams are licensing process technology and supplying catalysts.
Performance commentary
Sales
Sales declined 16% reflecting lower sales in both Catalysts - which represents the majority of sales - and Licensing.
Catalysts: sales driven by lower first fills
Catalysts sales were down 12%, largely driven by first fills. First fill volumes declined materially against a strong prior period in which several new plants came onstream in China, including one of the world's largest methanol plants.
In refills, sales were down slightly. We saw lower formaldehyde sales due to weak end markets, particularly in China, alongside lower methanol sales and a weaker performance in additives. This was partly offset by higher sales relating to synthetic natural gas.
Licensing: performance reflects timing of licence wins in core technologies
Licensing sales - which are lumpy in nature - declined 35% year-on-year, largely reflecting lower sales from our existing core technology portfolio in China, against a strong prior period. In sustainable technologies, whilst we saw lower sales from low carbon hydrogen projects, this was partly offset by increased engineering income from sustainable methanol projects where we have a good pipeline.
         
Notes:
1.1H 2024/25 is restated to reflect the group's updated reporting segments following the agreed sale of Catalyst Technologies, where a small business outside of the sale perimeter has moved from Catalyst Technologies to PGM Services.
Demand for sustainable technologies remains strong, and we continue to invest in R&D to support the development of the business. We won an additional two large scale projects in our sustainable technologies portfolio in the half, highlighting the good medium-term growth opportunity in Catalyst Technologies.
·DG Fuels' third sustainable aviation fuel facility - located in Minnesota, US
·USA BioEnergy's Bon Weir sustainable aviation fuel plant in Texas, US
Underlying operating profit
Underlying operating profit was down 60%as a result of lower sales and weaker mix reflecting the decline in Licensing sales which are higher margin.
   
Financial review - continuing operations
Research and development (R&D)
R&D spend (excluding Catalyst Technologies) was £69 million in the half, representing c.5% of sales excluding precious metals. This was down from £82 million in the prior period, largely driven byreduced R&D spend in Clean Air and Hydrogen Technologies.
Foreign exchange
The calculation of growth at constant rates excludes the impact of foreign exchange movements arising from the translation of overseas subsidiaries' profit into sterling. The group does not hedge the impact of translation effects on the income statement. The principal overseas currencies, which represented 85% of the non-sterling denominated underlying operating profit in the half year ended 30th September 2025, were:

For the half, the impact of exchange rates decreased sales by £26 million and underlying operating profit by £2 million.
If exchange rates as at 11th November 2025 (£:US$ 1.32, £:€ 1.14, £:INR 116.55,
£:RMB 9.38) are maintained throughout the remainder of the year ending 31st March 2026, foreign currency translation will have a limited effect on underlying operating profit. A one cent change in the average US dollar rate, a one cent change in the average Euro rate, a one rupee change in the average Indian rupee rate, and a ten fen change in the average Chinese renminbi rate would each impact operating profit by approximately £0.5 million, £1.1 million, £0.2 million and £0.1 million, respectively.

During the period, the group settled an insurance litigation and received proceeds of
£8 million.
There was a charge of £33 million relating to major impairment and restructuring costs, comprising £26 million of restructuring costs and an impairment charge of £7 million. The impairment charge relates to the consolidation of our manufacturing footprint in Clean Air. The restructuring costs related to rightsizing the group and Clean Air's ongoing footprint consolidation, as well as a one-off termination cost for a US pension scheme.
Finance charges
Net finance charges in the period amounted to £32 million, up from £23 million in the prior period. The increase of £9 million largely reflects the absence of non-recurring benefits recognised in the prior period.
Taxation
The tax charge on underlying profit before tax for the half year ended 30th September 2025 was £24 million, an effective underlying tax rate of 21.8%, compared with 20.5% in the first half of 2024/25.
The effective tax rate on reported profit for the half year ended 30th September 2025 was 119%. This represents a tax charge of £102 million, compared with £58 million in the first half of 2024/25. The increase largely reflects the impact of an £84 million deferred tax asset de-recognition as a result of the agreed divestment of Catalyst Technologies.
We expect the effective tax rate on underlying profit for the year ending 31st March 2026 to be around 22%.
Post-employment benefits
IFRS - accounting basis
At 30th September 2025, the group's net post-employment defined benefit position, was a surplus of £201 million. The cost of providing post-employment defined benefits in the period was £15 million, up from £12 million in the prior period, driven by a one-off termination cost in the US.
Capital expenditure
Capital expenditure (excluding Catalyst Technologies) was £94 million¹ in the half, 1.3 times depreciation and amortisation (1H 2024/25: £134 million, 1.7 times depreciation and amortisation). A key project in the period was investment in our new world-class PGM refinery.
Balance sheet
Net debt as at 30th September 2025 was £971 million, an increase from £810 million at 31st March 2025 and £799 million at 30th September 2024. The group's net debt to EBITDA was 2.0 times (31st March 2025: 1.8 times, 30th September 2024: 1.7 times).
We use short-term metal leases as part of our mix of funding for working capital, which are outside the scope of IFRS 16. Precious metal leases amounted to £279 million as at
30th September 2025 (31st March 2025: £202 million, 30th September 2024: £197 million).
       
Notes:
1.Cash outflow of £129 million in the period relating to capital expenditure (continuing basis). Difference reflects movements in capital accruals.
 
Free cash flow and working capital
Free cash flow¹ was a £4 million inflow compared to a £165 million outflow in the first half of 2024/25. This significant improvement year-on-year was driven by higher operating profit and improved working capital management in Clean Air and PGM Services.
Excluding precious metal, average working capital days (excluding Catalyst Technologies) to 30th September 2025 increased to 59 days compared to 51 days to 30th September 2024.
Going concern
The group maintains a healthy balance sheet with around £1.5 billion of available cash and undrawn committed facilities. Cash generation was positive during the period with a free cash inflow¹ of £4 million. Net debt at 30th September 2025 was £971 million. Net debt to underlying EBITDA was 2.0 times.
For assessing going concern, the base case scenarios were stress tested to a severe but plausible downside case which assumes lower demand across our markets to account for further disruptions and recession.
Additionally, the group considered scenarios including the impact from metal price volatility, delays in capital projects and delivery of cost savings, slow down of operations in China and an additional impact of US tariffs. We have also considered the impact of a refinery shutdown and other manufacturing plant shutdowns for a prolonged period. In all scenarios, the group has sufficient headroom against committed facilities and key financial covenants are not in breach during the going concern period.
Having assessed various scenario forecasts, the directors therefore reasonably expect no significant uncertainties about the group's ability to operate for at least fifteen months from the approval date of these half year accounts, supporting a going concern basis.
         
Notes:
1.Free cash flow defined as net cash flow from operating activities (excluding disposal related costs) after net interest paid, net purchases of non-current assets and investments and the principal elements of lease payments, adjusted to reflect the classification of Catalyst Technologies as a discontinued operation.
 
Risks and uncertainties
JM's principal risk landscape continues to be reviewed and updated to reflect our evolving strategy and the challenges that come from operating within the current global environment and economic climate. JM is committed to improving its risk management approach and insights used to support various business decisions. The group's principal risks are listed below and remain largely as disclosed in our 2025 Annual Report.
1.Cyber-attack/IT failure- Risks to our information technology and operational technology, including failure to adapt to evolving business needs, system disruptions or major cyber security incidents. These issues could impact business continuity, data integrity and compliance.
2.Capital expenditure- JM's growth depends on the effective allocation and execution of capital expenditure. Delays, cost overruns, poor investment decisions or ineffective management could undermine expected value, leading to inefficient resource use, reduced competitiveness and failure to meet market and customer needs.
3.Operational assets- Failure of one or more critical operational assets could disrupt JM's supply chains, performance and reputation. This risk includes ageing infrastructure as well as the growing impact of climate change, such as extreme weather events and natural disasters.
4.Security of metal- JM faces security risks due to the high value of its products, site locations and supply chain dependencies. These risks include internal theft, organised crime and challenges in metal reconciliation, which vary across different parts of the business.
5.Supply chain resilience- JM relies on a global network of suppliers for key materials and services, some of which are highly specialised with limited alternative sources. Emerging industries like hydrogen and sustainable aviation fuel have immature supply chains for raw materials, making them particularly vulnerable to disruptions.
6.Geopolitical/Economic- JM's global footprint exposes the business to potential disruptions from geopolitical and macroeconomic events, including conflicts, trade disputes, sanctions, pandemics, financial crises and economic instability in key markets.
7.Innovation- A failure to develop competitive solutions, such as products, licensing and technical services, that align with evolving customer needs and market trends. This includes challenges in identifying customer expectations, translating them into effective R&D and scaling new technologies for industrial use.
8.Talent, culture and engagement-A low-performing organisation characterised by an insufficiently engaged and inclusive workforce, or a misalignment of skills and talent, would impact our ability to execute our strategy successfully.
9.Market factors- JM may not accurately predict changes in customer demand, regulation, or market trends, particularly as industries move away from fossil fuels. There is also a risk of missing new opportunities or responding to change too slowly or quickly.
10.EHS- A major work-related EHS (Environmental, Health and Safety) incident, such as a fire, explosion or toxic gas release, could result from process safety failures or regulatory non-compliance, threatening JM's operations, product portfolios and reputation.
11. Implementation of cash-focused business model- JM is pivoting towards a
cash-focused business model, underpinned by rigorous cost control, improved working capital management, and disciplined capital allocation. Failure to successfully execute these programmes could impact the delivery of higher cash generation and enhanced shareholder returns.

Independent review report to Johnson Matthey Plc Report on the condensed consolidated interim financial statements   Our conclusion We have reviewed Johnson Matthey Plc's condensed consolidated interim financial statements (the "interim financial statements") in the half year results of Johnson Matthey Plc for the 6 month period ended 30th September 2025 (the "period"). Based on our review, nothing has come to our attention that causes us to believe that the interim financial statements are not prepared, in all material respects, in accordance with UK adopted International Accounting Standard 34, 'Interim Financial Reporting' and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority. The interim financial statements comprise: ·    the Condensed Consolidated Statement of Financial Position as at 30th September 2025; ·    the Condensed Consolidated Income Statement and Condensed Consolidated Statement of Total Comprehensive Income for the period then ended; ·    the Condensed Consolidated Statement of Cash Flows for the period then ended; ·    the Condensed Consolidated Statement of Changes in Equity for the period then ended; and ·    the explanatory notes to the interim financial statements. The interim financial statements included in the half year results of Johnson Matthey Plc have been prepared in accordance with UK adopted International Accounting Standard 34, 'Interim Financial Reporting' and the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority. Basis for conclusion We conducted our review in accordance with International Standard on Review Engagements (UK) 2410, 'Review of Interim Financial Information Performed by the Independent Auditor of the Entity' issued by the Financial Reporting Council for use in the United Kingdom ("ISRE (UK) 2410"). A review of interim financial information consists of making enquiries, primarily of persons responsible for financial and accounting matters, and applying analytical and other review procedures.   A review is substantially less in scope than an audit conducted in accordance with International Standards on Auditing (UK) and, consequently, does not enable us to obtain assurance that we would become aware of all significant matters that might be identified in an audit. Accordingly, we do not express an audit opinion.   We have read the other information contained in the half year results and considered whether it contains any apparent misstatements or material inconsistencies with the information in the interim financial statements.   Conclusions relating to going concern Based on our review procedures, which are less extensive than those performed in an audit as described in the Basis for conclusion section of this report, nothing has come to our attention to suggest that the directors have inappropriately adopted the going concern basis of accounting or that the directors have identified material uncertainties relating to going concern that are not appropriately disclosed. This conclusion is based on the review procedures performed in accordance with ISRE (UK) 2410. However, future events or conditions may cause the group to cease to continue as a going concern.   Responsibilities for the interim financial statements and the review   Our responsibilities and those of the directors The half year results, including the interim financial statements, is the responsibility of, and has been approved by the directors. The directors are responsible for preparing the half year results in accordance with the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority. In preparing the half year results, including the interim financial statements, the directors are responsible for assessing the group's ability to continue as a going concern, disclosing, as applicable, matters related to going concern and using the going concern basis of accounting unless the directors either intend to liquidate the group or to cease operations, or have no realistic alternative but to do so. Our responsibility is to express a conclusion on the interim financial statements in the half year results based on our review. Our conclusion, including our Conclusions relating to going concern, is based on procedures that are less extensive than audit procedures, as described in the Basis for conclusion paragraph of this report. This report, including the conclusion, has been prepared for and only for the company for the purpose of complying with the Disclosure Guidance and Transparency Rules sourcebook of the United Kingdom's Financial Conduct Authority and for no other purpose. We do not, in giving this conclusion, accept or assume responsibility for any other purpose or to any other person to whom this report is shown or into whose hands it may come save where expressly agreed by our prior consent in writing.     PricewaterhouseCoopers LLP Chartered Accountants London 20th November 2025 Condensed Consolidated Income Statement for the six months ended 30th September 2025

1Basis of preparation and statement of compliance
  These condensed consolidated interim financial statements for the half-year reporting period ended 30th September 2025 (the 'condensed consolidated accounts') have been prepared in accordance with UK-adopted International Accounting Standard 34, 'Interim Financial Reporting' and the Disclosure Guidance and Transparency Rules sourcebook of the UK's Financial Conduct Authority. The accounting policies, estimates and judgements applied in the condensed consolidated accounts are consistent with the accounting policies, estimates and judgements applied by the group in its consolidated accounts as at, and for the year ended, 31st March 2025, with the exception of the adoption of additional material accounting policies and amended standards as explained below.   These condensed consolidated accounts do not constitute statutory accounts within the meaning of Section 435 of the Companies Act 2006. They do not include all of the notes of the type normally included in an annual financial report. Accordingly, the condensed consolidated accounts should be read in conjunction with the annual report for the year ended 31st March 2025, which has been prepared in accordance with UK-adopted International Accounting Standards (IAS) and with the requirements of the Companies Act 2006.   Information in respect of the year ended 31st March 2025 is derived from the company's statutory accounts for that year which have been delivered to the Registrar of Companies. The auditor's report on those statutory accounts was unqualified, did not include a reference to any matters to which the auditor drew attention by way of emphasis without qualifying its report and did not contain any statement under Section 498 (2) or Section 498 (3) of the Companies Act 2006.   The condensed consolidated accounts are unaudited but have been reviewed by the auditors. They were approved by the board of directors on 20th November 2025.   Going concern The directors have reviewed a range of scenario forecasts for the group and have reasonable expectation that there are no material uncertainties that cast doubt about the group's ability to continue operating for at least fifteen months from the date of approving these condensed consolidated accounts.   As at 30th September 2025, the group maintains a healthy balance sheet with around £1.5 billion of available cash and undrawn committed facilities. Free cash flow from continuing operations during the period was a £4 million inflow with net debt increasing by £161 million. Net debt from continuing operations at 30th September 2025 was £971 million at 2.0 times net debt to underlying EBITDA which was at the top end of our current target range of 1.5-2.0x. Refer to note 17 for further information on these non-GAAP measures.   Despite stronger metal prices, steady inflation and interest rates starting to fall, significant headwinds remain due to ongoing global auto sector weakness, persistent geopolitical tensions, and political uncertainty particularly about tariffs. Despite these challenges, the group demonstrated resilience during the period, delivering strong underlying operating profit. For the purposes of assessing going concern, we have updated our financial projections using the latest forecast for our base case scenarios from a group perspective exclusive of Catalyst Technologies, in light of its ongoing divestment. This scenario assumes the receipt of net proceeds of £1.6 billion from the divestment of Catalyst Technologies, of which £1.4 billion is returned to shareholders and £200 million is retained. The base case scenario was stress tested to a 'severe but plausible' downside case which reflects lower demand across our markets to account for significant disruption from external factors and a deep recession.   The severe-but-plausible case for Clean Air modelled scenarios assuming a smaller light and heavy-duty vehicle market from reduced vehicle production and/or market consumer demand disruption, which could be caused by tariffs or other general changes to the market environment, or greater share of zero emission vehicles in market. This was assumed to result in a further 10% drop in sales from the base case. For PGM Services (PGMS), it also assumed a reduction in sales and associated operating profit based on adverse scenarios using external and internal market insights.  
1Basis of preparation and statement of compliance (continued)
  Going concern (continued) Additionally, the group considered scenarios including the impact from metal price volatility, delays in capital projects and delivery of cost transformation savings, slow down of operations in China and an additional impact of US tariffs. We have also considered the impact of a refinery shutdown and other manufacturing plant shutdowns for a prolonged period. Whilst the combined impact would reduce profitability and EBITDA against our latest forecast, we maintain strong liquidity and sufficient facilities/covenants headroom to retain access to financing arrangements.   The group has a robust funding position comprising a range of long-term debt and a £1 billion five year committed revolving credit facility (RCF) which was undrawn. There was £536 million of cash held in money market funds or placed on deposit with highly rated banks. Of the existing loans, £112 million of USPP debt will mature in the next 15 months. We assume no refinancing of this debt in the going concern modelling. As a long time, highly rated issuer in the US private placement market, the group expects to be able to access additional funding in its existing markets if required but the going concern conclusion is not dependent on such access as the company has sufficient financing and liquidity to fund its obligations in all scenarios. The group also has a number of additional sources of funding available including uncommitted metal lease facilities that support precious metal funding. Whilst we would fully expect to be able to utilise the metal lease facilities, they are also excluded from our going concern modelling.   Conclusion In all scenarios, the group has sufficient headroom against committed facilities and key financial covenants are not in breach during the going concern period. There remain risks to the group including more extreme economic outcomes. Against these, the group has a range of levers which it could utilise to protect headroom including reducing capital expenditure, renegotiating payment terms or reducing future dividend distributions.   The directors are therefore of the opinion that the group has adequate resources to fund its operations for the period of at least fifteen months following the date of approving these condensed consolidated accounts.   Non-GAAP measures The group uses various measures to manage its business which are not defined by generally accepted accounting principles (GAAP). The group's management believes these measures provide valuable additional information to users of the accounts in understanding the group's performance. The group's non-GAAP measures are defined and reconciled to GAAP measures in note 17.   Amended standards adopted by the group The IASB has issued the following amendments, which have been endorsed by the UK Endorsement Board, for annual periods beginning on or after 1st January 2025: -       Amendments to IAS 21, The Effects of Changes in Foreign Exchange Rates relating to exchangeability of a currency; -       Amendments to IFRS 9, Financial Instruments and IFRS 7, Financial Instruments: Disclosures The new or amended standards and interpretations above that are effective for the year ended 31st March 2026 have not had a material impact on the group. The group has not early adopted any standard, amendment or interpretation that was issued but is not yet effective.    
1Basis of preparation and statement of compliance (continued)
  Additional material accounting policies adopted by the group   Assets held for sale and discontinued operations Non-current assets and disposal groups are classified as held for sale, if available for sale in its present condition and a sale is considered highly probable within 12 months. They are measured at the lower of their carrying amount and fair value less costs to sell. Assets and liabilities classified as held for sale are presented separately on the Balance Sheet. The assets are not depreciated or amortised while they are classified as held for sale. An impairment loss is recognised in the Income Statement for any initial or subsequent write-down of the asset or disposal group to fair value less costs to sell. A gain is recognised for any subsequent increases in fair value less costs to sell of an asset or disposal group, but not in excess of any cumulative impairment loss previously recognised. A gain or loss not previously recognised by the date of the sale of the non-current asset (or disposal group) is recognised at the date of de-recognition. A discontinued operation is a component of the group's business that either has been disposed of, or that is classified as held for sale and represents a separate major line of business or geographical area of operations, is part of a single co-ordinated plan to dispose of a separate major line of business or geographical area of operations or is a subsidiary acquired exclusively with a view to resale. Classification as a discontinued operation occurs at the earlier of disposal or when the operation meets the criteria to be classified as held for sale. The results of discontinued operations are presented separately in the Income Statement. When an operation is classified as a discontinued operation, the comparative Income Statement and Statement of Total Comprehensive Income is restated as if the operation had been discontinued from the start of the comparative year. The group has elected to present assets and liabilities held for sale and transactions relating to discontinued operations on a net basis i.e. after adjusting for intercompany eliminations as part of consolidation. The policy has been applied consistently to all periods presented in which discontinued operations are reported. Judgements made in applying accounting policies Assets held for sale and discontinued operations On 22nd May 2025, the group announced the agreement of the sale of its Catalyst Technologies business to Honeywell International Inc., refer to note 11 for further information. At the balance sheet date, the sale was considered highly probable and therefore management concluded that the criteria of IFRS 5 for classification as held for sale at 30th September 2025 has been met. Additionally, as a separately reported operating segment the disposal group is deemed a major line of business which therefore meets the criteria for classification as a discontinued operation. Consequently, the Catalyst Technologies business has been classified as held for sale and a discontinued operation within these condensed consolidated accounts.

Metal revenue: Metal revenue relates to the sales of precious metals to customers, either in pure form or contained within a product. Metal revenue arises in each of the reportable segments in the group. Metal revenue is affected by fluctuations in the market prices of precious metals and, in many cases, the value of precious metals is passed directly on to customers. Given the high value of these metals this makes up a significant proportion of revenue

  Non underlying items are shown separately on the face of the income statement and excluded from underlying operating profit, see note 17.   Profit on disposal of businesses On 30th April 2024, the group completed the sale of Battery Systems, on 1st July 2024, the group completed the sale of its Medical Device Components business. On 24th July 2024, the group completed the sale of the land and buildings from our legacy Battery Materials business in Poland.   Gain on significant legal proceedings During the period the group settled an insurance litigation and received proceeds of £8 million.   Major impairment and restructuring charges Major impairments - the group's impairment charge of £7 million relates to production related assets in Clean Air as the business continues to consolidate its existing capacity into more efficient plants.   Major restructuring - restructuring charges of £26 million have been recognised of which £13 million is as a result of us rightsizing the group to ensure it is leaner and more efficient in the future. During the period there was also a one-off termination cost of £7 million for a US pension scheme which was closed to accrual in June 2023. The remaining £6 million charge is related to Clean Air's ongoing plant consolidation initiatives, of which the majority is redundancy and exit costs.  
5Tax expense
The charge for taxation for continuing operations at the half year ended 30th September 2025 is £102 million (1H 2024/25: £58 million), an effective tax rate of 119%. This tax charge includes £78 million equating to an effective tax rate of 98% (for deferred tax assets not being recognised in the current period of £84 million offset by the UK IFRIC23 reversal of £6 million), due to the impact of the proposed Catalyst Technologies business disposal.   The tax charge on underlying profit before tax on continuing operations was £24 million, an effective tax rate of 21.8%, compared to the 20.5% in the half year ended 30th September 2024. Excluding discrete items, the tax charge on underlying profit before tax on continuing operations was £23 million, an effective tax rate of 20.9% compared to 18.3% in the half year ended 30th September 2024.   Deferred tax assets are recognised only to the extent that it is probable that future taxable profits will be available against which the assets can be utilised. The recoverability of deferred tax assets is supported by future taxable profits where available. Where there are insufficient future taxable profits, deferred tax assets are recognised against future taxable income arising from the reversal of deferred tax liabilities. As above, a £84 million deferred tax asset relating to the UK profitability has not been recognised in the current period.   The group is within the scope of the OECD Pillar Two model rules. The group is in scope by virtue of the parent company being tax resident in the UK. Pillar Two legislation has been enacted in the UK, as well as several other territories where the group operates. The group applies the exception to recognising and disclosing information about deferred tax assets and liabilities related to Pillar Two model rules, as provided in the amendments to IAS 12 issued in May 2023.   Under the UK legislation, the group is liable to pay a top-up tax for the difference between its Global Anti-Base Erosion ('GloBE') effective tax rate per jurisdiction and the 15% minimum rate. Based on an initial analysis of the current year financial data, most jurisdictions in which the group operates are expected to qualify for one of the safe harbour exemptions such that top-up taxes should not apply or where the safe harbour exemptions do not apply, no top-up taxes are expected to arise under the full GloBE calculation. In jurisdictions where neither of this is the case, the reported tax charge includes income tax of £1.6 million related to Pillar Two income tax. We continue to monitor potential impacts to the level of necessary provision as further OECD guidance is published, including, as territories implement legislation to enact the rules, and as territories increase their domestic Corporate Tax rate in response to the OECD Pillar Two rules.

1During the period the group completed the buy-out of its US defined benefit salaried scheme following its closure to accrual on 30th June 2023. This resulted in a one-off termination cost of £7 million (see note 4) and a reduction in the pension assets and pension liabilities of £157 million.

13Fair values
Fair value hierarchy Fair values are measured using a hierarchy where the inputs are: ·    Level 1 ─ quoted prices in active markets for identical assets or liabilities. ·    Level 2 ─ not level 1 but are observable for that asset or liability either directly or indirectly. ·    Level 3 ─ not based on observable market data (unobservable).   Fair value of financial instruments Certain of the group's financial instruments are held at fair value. The fair value of a financial instrument is the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the balance sheet date. The fair value of forward foreign exchange contracts, interest rate swaps, forward precious metal price contracts and currency swaps is estimated by discounting the future contractual cash flows using forward exchange rates, interest rates and prices at the balance sheet date. The fair value of trade and other receivables measured at fair value is the face value of the receivable less the estimated costs of converting the receivable into cash. The fair value of money market funds is calculated by multiplying the net asset value per share by the investment held at the balance sheet date. There were no transfers of any financial instrument between the levels of the fair value hierarchy during the current or prior periods.

3Trade receivables held in a part of the group with a business model to hold trade receivables for collection or sale. The remainder of the group operates a hold to collect business model and receives the face value, plus relevant interest, of its trade receivables from the counterparty without otherwise exchanging or disposing of such instruments.

14Precious metal leases
At 30th September 2025, precious metal leases were £279 million at closing prices (31st March 2025: £202 million). Precious metal leases do not fall under the scope of IFRS 16.  
15Transactions with related parties
There have been no material changes in related party relationships in the six months ended 30th September 2025. During the half year ended 30th September 2025, the group had sales with associates totalling £2 million (1H 2024/25: £2 million). The amounts owed by Veranova were £1 million at 30th September 2025 (1H 2024/25: £1 million). No other related party transactions have occurred which have materially affected the financial position or performance of the group during the period.  
16Contingent liabilities
The group is involved in various disputes and claims which arise from time to time in the course of its business including, for example, in relation to commercial matters, product quality or liability, employee matters and tax audits. The group is also involved from time to time in the course of its business in legal proceedings and actions, engagement with regulatory authorities and in dispute resolution processes. These are reviewed on a regular basis and, where possible, an estimate is made of the potential financial impact on the group. In appropriate cases a provision is recognised based on advice, best estimates and management judgement. Where it is too early to determine the likely outcome of these matters, no provision is made. Whilst the group cannot predict the outcome of any current or future such matters with any certainty, it currently believes the likelihood of any material liabilities to be low, and that such liabilities, if any, will not have a material adverse effect on its consolidated income, financial position or cash flows.   Following the sale of its Health business in May 2022, the purchaser of the Health business, Veranova Bidco LP, has issued a claim against the group in connection with certain warranties given in the sale and purchase agreement dated 16th December 2021 at the time of signing. Having reviewed the claim with its advisers, the group is of the opinion that it has a defensible position in respect of these allegations and is vigorously defending its position. The outcome of the legal proceedings relating to this matter is not certain, since the issues of liability and quantum will be for determination by the court at trial. Accordingly, the group is unable to make a reliable estimate of the possible financial impact at this stage, if any.  
17Non-GAAP measures
The group uses various measures to manage its business which are not defined by generally accepted accounting principles (GAAP). The group's management believes these measures provide valuable additional information to users of the accounts in understanding the group's performance. Certain of these measures are financial Key Performance Indicators which measure progress against our strategy.   All non-GAAP measures are on a continuing operations basis.  
17Non-GAAP measures (continued)
Definitions
MeasureDefinitionPurpose
Sales1Revenue excluding cost of precious metals to customers and the precious metal content of products sold to customers.Provides a better measure of the growth of the group as revenue can be heavily distorted by year on year fluctuations in the market prices of precious metals and, in many cases, the value of precious metals is passed directly on to customers.
Underlying operating profit2Operating profit excluding non-underlying items.Provides a measure of operating profitability that is comparable over time.
Underlying operating profit margin1,2Underlying operating profit divided by sales.Provides a measure of how we convert our sales into underlying operating profit and the efficiency of our business.
Underlying profit before tax2Profit before tax excluding non-underlying items.Provides a measure of profitability that is comparable over time.
Underlying profit for the year2Profit for the year excluding non-underlying items and related tax effects.Provides a measure of profitability that is comparable over time.
Underlying earnings per share1,2Underlying profit for the year divided by the weighted average number of shares in issue.Our principal measure used to assess the overall profitability of the group.
Return on capital employed (ROCE)1Annualised underlying operating profit divided by the average equity plus average net debt. The average is calculated using the opening balance for the financial year and the closing balance.Provides a measure of the group's efficiency in allocating the capital under its control to profitable investments.
Average working capital days (excluding precious metals)1Monthly average of non-precious metal related inventories, trade and other receivables and trade and other payables (including any classified as held for sale) divided by sales for the last three months multiplied by 90 days.Provides a measure of efficiency in the business with lower days driving higher returns and a healthier liquidity position for the group.
Free cashflow3Net cash flow from operating activities(excluding disposal related costs)after net interest paid, net purchases of non-current assets and investments, and the principal element of lease payments.Provides a measure of the cash the group generates through its operations, less capital expenditure.
Net debt to underlyingEBITDA3Net debt, including quoted bonds purchased to fund the UK pension (excluded when the UK pension plan is in surplus) divided by underlying EBITDA for the same period.Provides a measure of the group's ability to repay its debt. The group has a long-term target of net debt to underlying EBITDA of between 1.5 and 2.0 times, although in any given year it may fall outside this range depending on future plans.
1 Key Performance Indicator 2 Underlying profit measures are before profit or loss on disposal of businesses, gain on significant legal proceedings, major impairment and restructuring charges, share of profits or losses from non-strategic equity investments, one-off tax transactions and, where relevant, related tax effects. These items have been excluded by management as they are not deemed to be relevant to an understanding of the underlying performance of the business. 3 The definition of these non-GAAP measures have been redefined in the current period to give better clarity and transparency and more closely align with the purpose of the non-GAAP measure.
