FOR IMMEDIATE RELEASE

Agreement to sell Catalyst Technologies business for £1.8bn with cash return of £1.4bn - delivering substantial value to JM shareholders

Johnson Matthey Plc ("JM" or the "Group") is pleased to announce that it has reached an agreement to sell its Catalyst Technologies business ("CT") to Honeywell International, Inc. ("Honeywell") at an enterprise value of £1,800m on a cash and debt-free basis (the "Transaction"). The Transaction is expected to deliver net sale proceeds of c.£1.6bn to the Group, subject to customary closing adjustments.

Following the sale of CT, JM will be repositioned as a highly streamlined group focused on Clean Air and PGMS, driving sustained strong cash generation to support attractive ongoing returns to shareholders. The sale of CT, together with the compelling investment proposition of JM, are expected to deliver substantial value to JM shareholders.

Key Highlights

·    Highly attractive CT sale valuation: enterprise value of £1,800m on a cash and debt-free basis, representing a transaction multiple of 13.3x EBITDA¹

·     Significant cash return to shareholders: £1.4bn (equivalent to c.88% of expected net sale proceeds and c.£8 per JM share) expected to be returned to shareholders following completion of the Transaction, which is expected by the first half of calendar year 2026

·      JM to be repositioned as a highly streamlined group with a compelling investment proposition focused on delivering sustained strong cash generation and attractive ongoing cash returns to shareholders

o  Sustained scale and leadership: Group to be focused on its leading global Clean Air and PGMS businesses, operating in large and durable addressable markets with attractive long-term prospects

o  Deep and longstanding platinum group metals expertise: underpinning JM's strong  commercial advantages and leading positions

o   Operating profit growth: enhanced operating efficiencies as the Group transitions to a more focused and rationalised operating model, supporting the delivery of at least mid-single digit CAGR in pro forma² Group underlying operating profit from FY2024/25 to FY2027/28

o   Sustained strong cash generation: a material increase in Group cash generation to at least £250m of Group free cash flow by FY2027/28, underpinned by growth in underlying operating profit, capex reducing to close to maintenance levels and material working capital benefits

o Higher ongoing returns to shareholders under a refreshed capital allocation framework, in addition to the cash return pursuant to the Transaction: total annual cash returns to shareholders of at least £130m for FY2025/26³, growing to at least £200m for FY2026/27 and beyond⁴

·      Delivering substantial near, mid and longer-term value for JM shareholders through the sale of CT and continued exposure to the attractive investment proposition of JM

Patrick Thomas, Chair of Johnson Matthey, said: "On behalf of the Board, we are pleased to announce the sale of CT which, together with the refreshed strategy of the Group, represents a strategically and financially compelling proposition for shareholders. Today's transaction realises significant value for shareholders, creating a Group with the core strengths, focus and discipline to deliver strong returns for shareholders into the future."

Liam Condon, Chief Executive of Johnson Matthey, said: "Today's announcement represents a significant milestone in the history of Johnson Matthey. Following on from the divestment of our Medical Devices business at a highly attractive valuation, we have now agreed to the sale of our Catalyst Technologies business for £1.8bn. This allows JM to realise a very attractive valuation for this business that fully reflects its strong long-term growth prospects. We will now fundamentally re-shape Johnson Matthey into a more focused and leaner business. This will better position us to leverage our strong capabilities and leading market positions in Clean Air and PGM Services to drive a step change in sustainable cash generation with higher returns to shareholders. JM is a great company and we are confident that the actions we have announced today will deliver substantial and sustainable value to our shareholders."

Strategic Rationale and Benefits of the Transaction

CT is a global leader in the licensing of process technology and supply of catalysts. Under the Group's strategy, CT has delivered significant commercial wins and partnerships, and developed a pipeline of more than 150 projects in its sustainable technologies portfolio that is expected to deliver attractive long-term profitable growth as the world transitions to net zero.

Following a period of engagement with Honeywell, the Board of JM concluded that the terms of the Transaction represent a compelling value proposition for JM shareholders. In particular, the Board believes that:

·   The enterprise value of £1,800m fully reflects the long-term growth prospects of CT, including the delivery of CT's sustainable technologies project pipeline

·     The financial terms of the Transaction are highly attractive in comparison to key valuation benchmarks. In particular:

o  The enterprise value of £1,800m represents a significant premium to the average CT sell-side analyst valuation of £945m⁵; and

o  The implied transaction multiple represents a significant premium to the current JM Group trading multiple of 5.7x FY2024/25 EV/EBITDA⁶

·   The all-cash nature of the consideration will enable a meaningful cash return to JM shareholders, expected to be £1.4bn (equivalent to c.£8 per JM share and c.88% of expected net sale proceeds)

Following the sale of CT, the Group will be focused on its leading positions in Clean Air and PGMS, in which JM has strong commercial advantages given its deep and longstanding platinum group metals expertise. The Group has also launched a number of actions to deliver further enhanced operating efficiencies, sustainably strong operating profit growth, cash generation and attractive returns to JM shareholders over the medium term. Further details on the Group's strategic and financial investment proposition are set out in JM's preliminary results announcement for FY2024/25.

On this basis, the Board of JM has unanimously approved the Transaction and believes the terms of the Transaction are in the best interests of JM and JM's shareholders as a whole.

Use of Proceeds

Under the terms of the Transaction, CT is being sold for an enterprise value of £1.8bn on a cash and debt-free basis.

After deducting one-off payments and costs associated with the Transaction of c.£0.2bn (including tax, pension contribution and other transaction costs), this implies total net proceeds of c.£1.6bn to the Group (subject to customary closing adjustments). JM intends to return £1.4bn of these proceeds to JM shareholders following the completion of the Transaction via an appropriate return of value ("Return of Value"). JM expects to provide a further update on the Return of Value mechanism(s) and timing prior to completion of the Transaction.

The remaining c.£0.2bn of total net proceeds will be retained by the Group for general corporate purposes following completion of the Transaction. On a pro forma basis, this implies a reduction in the Group leverage multiple, which would be comfortably within the Group's new target leverage range of 1.0x-1.5x net debt to EBITDA over the medium term.

Financial Details on Catalyst Technologies and Impact on the Group

As at 31^st March 2025, the value of the gross assets of CT was £1,561m. For the fiscal year ended 31^st March 2025, the CT underlying EBITDA was £119m and the CT underlying operating profit was £92m.

Based on financials as at 31^st March 2025, the financial impacts of the Transaction on the Group are currently expected to be as follows:

·      The Group's pro forma total underlying operating profit for the fiscal year ended 31^st March 2025 would be £297m (representing a £92m adjustment);

·      The Group's pro forma total assets as at 31^st March 2025 would be £4,633m (representing a £1,561m adjustment); and

·      The Group's pro forma total liabilities as at 31^st March 2025 would be £2,912m (representing a £987m adjustment).

Next Steps

The Transaction is subject to customary conditions, including the receipt of certain customary regulatory approvals, and is expected to close by the first half of calendar year 2026.

UK Listing Rules

Due to the size of the Transaction in relation to the Group, it constitutes a Significant Transaction for the purposes of the UK Listing Rules made by the Financial Conduct Authority (the "FCA") for the purposes of Part VI of the Financial Services and Markets Act 2000 (as amended), which came into effect on 29^th July 2024 (the "UKLRs") and is therefore notifiable in accordance with UKLR 7.3.1R and 7.3.2R. In accordance with the UKLRs, the Transaction is not subject to shareholder approval.

Appendix 1 - Summary of the Principal Terms of the Transaction

Share Purchase Agreement

Parties and structure:

The Transaction is governed by the share purchase agreement ("Share Purchase Agreement") entered into between Johnson Matthey Plc ("JM") and Honeywell International, Inc. ("Honeywell"). Pursuant to the Share Purchase Agreement and subject to the Conditions (as defined below), JM has agreed to sell and Honeywell has agreed to purchase the entire issued share capital of each of Johnson Matthey Davy Technologies Limited, Johnson Matthey Chemicals GmbH and Johnson Matthey Process Technologies, Inc., which, together with their subsidiaries, will, as at Completion, hold the CT business.

Conditions:

The Transaction is subject to obtaining approvals from certain antitrust and other regulatory authorities (including in the UK, US and China) and the completion (in all material respects) of the reorganisation of the CT business within the Transaction perimeter.

The long stop date for satisfaction of the conditions (the "Long Stop Date") is 21 February 2026. In the event that any of the antitrust approvals are not satisfied by the Long Stop Date, the Long Stop Date may be extended where certain conditions are met.

Consideration:

The consideration for the Transaction is calculated on the basis of an enterprise value of £1.8 billion, adjusted to reflect customary normalisation of working capital, the settlement of inter-company balances and net debt as at the date of Completion.

Warranties and indemnities:

JM has given customary fundamental warranties relating to its title to the shares in the target companies, as well as to its own capacity and solvency. JM has also given customary limited fundamental warranties relating to the nature of the CT business.

Warranty and indemnity insurance is in place in respect of the majority of warranties given by JM under the Share Purchase Agreement and JM's liability in relation to those warranties is capped at £1.

JM has given indemnities in respect of certain matters relating to the CT business and the reorganisation of the CT business prior to Completion, including in respect of certain environmental, tax, pensions and litigation matters. Such indemnities are subject to limitations with regards quantum and time period.

Termination:

The Share Purchase Agreement may be terminated by either party if any of the conditions to the transaction described above are not satisfied or (if capable of waiver) waived on or before the Long Stop Date (subject to postponements of the Long Stop Date, and the party electing to terminate having complied in all material respects with its obligations under the Share Purchase Agreement relating to the satisfaction of the conditions).

Governing law and jurisdiction:

The Share Purchase Agreement is governed by English law. The English courts will have exclusive jurisdiction to settle any dispute arising out of or in connection with the agreement.

Appendix 3 - Additional Information (in relation to JM and CT)

Risks  

The risks disclosed below are those which JM considers: (i) are material risks related to the Transaction; (ii) will be new material risks to the Group as a result of the Transaction; or (iii) are existing material risks for the Group which will be impacted by the Transaction. Shareholders should carefully consider the risks and uncertainties described below, together with all other information contained in this announcement. The risks described below are not set out in any order of priority, assumed or otherwise.

Risks relating to the Transaction

(i) The Transaction may not proceed to Completion

Completion of the Share Purchase Agreement is subject to, among other things, the consent of relevant antitrust and other regulatory authorities. There can be no assurance that the conditions precedent to the Share Purchase Agreement will be satisfied (or waived, if applicable) and, accordingly, that Completion of the Transaction will take place.

If Completion of the Transaction does not occur, JM will not receive the cash proceeds from it. Further, some other costs incurred by the JM Group in connection with the Transaction (such as legal and other advisory fees) would be incurred without the receipt of those cash proceeds.

If the Transaction does not proceed to Completion, there can be no guarantee that JM will be able to secure another transaction involving the CT business on terms more favourable than, or equivalent to, the Transaction.

In addition, non-completion of the Transaction could erode confidence among investors and stakeholders. This could, in turn, have a material adverse effect on JM's business prospects, financial results and overall financial condition. Failure to complete the Transaction may also have a negative impact on the Group's ability to deliver on its future strategy. This may be the case even if the failure to complete the Transaction is outside of JM's control.

If the Transaction does not proceed to Completion, this may lead to management and employee distraction due to perceived uncertainty in the future of the CT business. This may, in turn, affect the profitability of the JM Group. Uncertainty around JM's commitment to the CT business might lead suppliers and customers of the CT business to feel it is not in their commercial interests to continue to do business with the CT business. The failure to implement the Transaction may therefore have an adverse effect on the performance of the CT business and its value to JM, which may adversely affect JM's share price.

(ii) Exposure to liabilities and restrictions under the SPA

The Share Purchase Agreement contains obligations in the form of warranties, indemnities, certain pre-Completion undertakings and a number of customary post-Completion restrictive covenants in favour of Honeywell. JM has taken steps to minimise the risk of liability through customary limitations on liability and sought to ensure that the restrictive covenants will not impact JM's business as currently carried on. However, the limitations on liability will not apply in all scenarios and any liability to make a payment arising from a successful claim by Honeywell under the Share Purchase Agreement could reduce the consideration and have an adverse effect on its business, results of operations, prospects and financial condition. Similarly, restrictive covenants applicable to JM could also have an adverse effect on its ability to pursue future opportunities and therefore its business, results of operations, prospects and financial condition.

JM has undertaken a customary disclosure process to minimise the risk of liability under these provisions and Honeywell has put in place a policy of warranty and indemnity insurance ("W&I Insurance") in respect of such liabilities typical for a transaction of this nature. However, such W&I Insurance may be insufficient or may not operate so as to preclude the possibility of claims being made against JM.

(iii) Pre-Completion changes affecting the CT business and the Continuing Group

During the period from the signing of the Share Purchase Agreement to Completion of the Transaction, events or developments may occur, including changes in trading, operations or outlook of the Continuing Group or the CT business, or external market factors, which could make the terms of the Share Purchase Agreement less attractive for JM. JM and Honeywell would be obliged to complete the Transaction notwithstanding such events or developments. This may have an adverse effect on the Continuing Group's business, results of operations, financial condition and prospects.

New material risks relating to the Continuing Group

If the Transaction is completed, the following risks and uncertainties may occur or result as a consequence:

(i) JM will be dependent on the business of the Continuing Group which will be less diversified and profits will be lower

Following Completion of the Transaction, the Continuing Group's business will be smaller and less diversified. Without the benefit of the revenues or profits of the CT business, the Continuing Group's profits will be lower and its overall financial performance will depend more on the performance of each of its continuing operations and the success of its business strategy.

In particular, and noting that Clean Air generates the majority of revenues, any underperformance by any business or division within the Continuing Group will have a larger relative impact on the Continuing Group than would have been the case before the Transaction. Furthermore, the business of the Continuing Group may be more susceptible to adverse economic changes than would have been the case prior to the Transaction.

(ii) The Transaction may have a disruptive effect on the Continuing Group

The Transaction has required, and will continue to require, substantial amounts of investment, time and focus from the management teams and employees of JM which could otherwise be spent operating the JM Group in the ordinary course. Key managers and employees may become distracted by the Transaction and, accordingly, decision-making at JM may be delayed, deferred or otherwise impacted. This disruption could be prolonged if Completion of the Transaction is materially delayed. Further, if key managers and employees of the Continuing Group decide to leave, the Continuing Group may incur additional costs in recruiting and attempting to recruit appropriate replacements, and there can be no assurance that the Continuing Group will be able to identify suitably talented or qualified replacements. The loss of any such key persons may have a material disruptive effect on the provision of services to the Continuing Group and as a result, may have a material adverse effect on the Continuing Group's business, results of operations, financial condition and prospects.

(iii) The quantum, timing and form of the Return of Value will be determined by the Board in due course

Whilst JM has announced (in this announcement) its intention to carry out the Return of Value (being a return of £1.4bn) following Completion of the Transaction, the quantum, timing and form of any such return of value shall be at the discretion of the Board and is subject to the Board continuing to believe that such declaration is in the best interests of shareholders at the time. The tax treatment of the Return of Value for shareholders and any risks arising therefrom will be impacted by the determination as to the form of the Return of Value in due course.

Existing material risks relating to the Group that will be impacted by the Transaction

Shareholders should be aware that the value of an investment in JM may go down as well as up and can be volatile. The price at which shares in JM may be quoted and the price which investors may realise for their shares will be influenced by a large number of factors, some specific to JM and its operations and some which may affect producers of chemicals and industrial catalysts or publicly traded companies as a whole, or other comparable companies. The sentiments of the stock market regarding the Transaction and the position of JM following its Completion will be one such factor and this, together with other factors including actual or anticipated fluctuations in financial performance of JM and its competitors, market fluctuations, and legislative or regulatory changes for the sector, could lead to the market price of the shares in JM going up or down.
