FOR IMMEDIATE RELEASE

7 April 2026

RECOMMENDED CASH ACQUISITION

of

Senior plc ("Senior")
by

 Zeus UK Bidco Limited ("BidCo")

(a newly formed company to be indirectly controlled by investment funds advised by affiliates of Tinicum Incorporated and Blackstone Inc. (the "Consortium"))

Summary

·       ​The boards of BidCo and Senior are pleased to announce that they have reached agreement on the terms of a recommended cash acquisition pursuant to which BidCo shall acquire the entire issued and to be issued ordinary share capital of Senior (other than the Existing Tinicum Shares) (the "Acquisition"). The Acquisition is to be effected by means of a scheme of arrangement under Part 26 of the Companies Act.

·          Under the terms of the Acquisition, Scheme Shareholders shall be entitled to receive a total value of:

300 pence per Scheme Share

comprising, for each Scheme Share:

o  297.85 pence in cash from BidCo (the "Cash Consideration"); and

o  the FY25 Final Dividend of 2.15 pence, which Scheme Shareholders may receive and retain, if the FY25 Final Dividend is approved by Senior Shareholders at Senior's Annual General Meeting, without any reduction to the Cash Consideration.

·           The Cash Consideration represents a premium of approximately:

o  36.6 per cent. to the volume-weighted average price of 218.10 pence in the six months to 26 February 2026 (being the last Business Day prior to the start of the Offer Period);

o  53.3 per cent. to the volume-weighted average price of 194.34 pence in the twelve months to 26 February 2026 (being the last Business Day prior to the start of the Offer Period); and

o  2.8 per cent. to the Closing Price per Senior Share of 289.80 pence on 2 April 2026 (being the latest practicable date prior to publication of this announcement).

·     The Cash Consideration values the entire issued and to be issued ordinary share capital of Senior at approximately £1,275 million on a fully diluted basis and implies an enterprise value of approximately £1,399 million (the "Implied Enterprise Value"). The Implied Enterprise Value represents a multiple of 15.2x Senior's adjusted EBITDA and 22.0x Senior's adjusted operating profit for the year ended 31 December 2025.

·       The Cash Consideration assumes that, other than the FY25 Final Dividend, Senior Shareholders shall not receive any dividend, distribution or other return of value. If, on or after the date of this announcement and on or prior to the Effective Date, and other than the FY25 Final Dividend, any dividend, distribution or other return of value is declared, made, or paid or becomes payable by Senior, BidCo reserves the right to reduce the Cash Consideration by an amount up to the amount of such dividend, distribution or other return of value, in which case references to the Cash Consideration shall be deemed to be a reference to the Cash Consideration as so reduced. In such circumstances, Senior Shareholders shall be entitled to retain any such dividend, distribution or other return of value declared, made, or paid.

·      The Senior Directors, who have been so advised by Lazard as to the financial terms of the Acquisition, consider the terms of the Acquisition to be fair and reasonable. In providing its advice to the Senior Directors, Lazard has taken into account the commercial assessments of the Senior Directors. Lazard is providing independent financial advice to the Senior Directors for the purposes of Rule 3 of the Code.

·       Accordingly, the Senior Directors intend to recommend unanimously that Senior Shareholders vote in favour of the Scheme at the Court Meeting and the resolutions to be proposed at the General Meeting as the Senior Directors have irrevocably undertaken to do in respect of their own beneficial holdings of 2,620,740 Senior Shares representing, in aggregate, approximately 0.6 per cent. of the ordinary share capital of Senior, and approximately 0.6 per cent. of the Scheme Shares, in each case in issue on 2 April 2026 (being the latest practicable date prior to this announcement).

·         BidCo has also received an irrevocable undertaking to vote in favour of the Scheme at the Court Meeting and the resolutions to be proposed at the General Meeting from Alantra in respect of a total of 72,307,009 Senior Shares representing, in aggregate, approximately 17.2 per cent. of Senior's ordinary share capital, and approximately 17.7 per cent. of the Scheme Shares, in each case in issue on 2 April 2026 (being the latest practicable date prior to this announcement).

·        BidCo has therefore received irrevocable undertakings in respect of a total of 74,927,749 Scheme Shares representing, in aggregate, approximately 17.9 per cent. of Senior's ordinary share capital, and approximately 18.3 per cent. of the Scheme Shares, in each case in issue on 2 April 2026 (being the latest practicable date prior to this announcement).

·          Further details of these irrevocable undertakings are set out in Appendix III to this announcement.

·       As a result, BidCo and the members of the Consortium own or control, or have received an irrevocable undertaking in respect of, Senior Shares that represent in aggregate, approximately 20.2 per cent. of Senior's ordinary share capital in issue on 2 April 2026 (being the latest practicable date prior to this announcement).

Key Highlights

·        Experience and history of investing in highly engineered aerospace and industrial components: The Consortium has a strong track record of investing in, supporting and improving highly engineered aerospace and industrial components businesses, and considers this experience directly relevant to Senior and its end markets. The Consortium's most recent aerospace investment was the acquisition of TriMas Aerospace, which has been combined with PennAero to form a leading manufacturer of aerospace fasteners and related specialty components.

·       AeroFlow Technologies adds attractive industrial rationale for the transaction: A key element of the Consortium's rationale is Tinicum's recent acquisition of AeroFlow Technologies, which the Consortium will place under common ownership with Senior as part of the Acquisition. The Consortium believes AeroFlow Technologies would provide a complementary source of adjacent aerospace exposure and additional earnings resilience within the combined platform, while also reinforcing the Consortium's familiarity with relevant aerospace products and end markets.

·      Active ownership to strengthen customer relationships: The Consortium believes that its broader sector footprint, active operating engagement and experience across aerospace programmes would support Senior in strengthening its customer relationships, deepening industry connectivity, reinforcing its strategic relevance and enhancing the overall strength of the combined platform's customer offering.

·        Access to deeper pools of aerospace manufacturing talent: The Consortium believes that companies within its portfolio are regarded as employers of choice in the highly competitive aerospace manufacturing market, which could provide Senior with access to a deeper pool of talent in certain of its important production facilities where labour availability and specialised technical capability are particularly important.

·     Long-term private ownership supports growth and disciplined optimisation: The Consortium believes Senior would benefit from the flexibility available under private ownership to pursue targeted organic and inorganic growth opportunities without public market expectations and requirements, while also optimising the portfolio and cost structure in a flexible and disciplined manner. Supported by a longer investment horizon than traditional private equity, this ownership model would provide Senior with access to long-term capital and the flexibility to accelerate investment in operations, customer offerings, R&D and selective M&A, without the constraints of a fixed exit timetable.

Timetable and Conditions

·       It is intended that the Acquisition shall be effected by means of a Court-approved scheme of arrangement under Part 26 of the Companies Act, although BidCo reserves the right to implement the Acquisition by means of a Takeover Offer (subject to Panel consent and the terms of the Co-operation Agreement).

·   Funds affiliated with Tinicum already hold in aggregate 9,917,706 Senior Shares (representing approximately 2.36 per cent. of Senior's issued ordinary share capital as at 2 April 2026, being the latest practicable date prior to the date of this announcement). These Senior Shares will not be Scheme Shares and will not be acquired by BidCo pursuant to the Acquisition, but will be acquired by BidCo on or as soon as practicable after the Effective Date. Tinicum will not be permitted to vote such Existing Tinicum Shares at the Court Meeting, but will be permitted to vote such Existing Tinicum Shares at the General Meeting.

·     The Acquisition is conditional on the approval of Senior Shareholders and is subject to the further Conditions and terms set out in Appendix I to this announcement, and to the full terms and conditions which shall be set out in the Scheme Document.

·         It is the Consortium's intention to place Senior and AeroFlow Technologies under common ownership as part of the Acquisition. Given the material significance of common ownership of Senior and AeroFlow Technologies to the Consortium's strategic rationale for the Acquisition, Senior Shareholders should be aware that certain of the Conditions set out in paragraph 3 of Part A of Appendix I relate to Blackstone acquiring an indirect interest in AeroFlow Technologies and if such Conditions are not satisfied, it would be BidCo's intention to seek the Panel's consent to invoke such Condition(s) to cause the Acquisition to lapse.

·        The Acquisition shall be put to Scheme Shareholders at the Court Meeting and Senior Shareholders at the General Meeting. In order to become effective, the Scheme must be approved by a majority in number of Scheme Shareholders voting at the Court Meeting, either in person or by proxy, representing at least 75 per cent. in value of the Scheme Shares validly voted. In addition, a special resolution required to implement the Scheme must be passed by Senior Shareholders representing at least 75 per cent. of votes validly cast at the General Meeting.

·        The Scheme Document, containing further information about the Acquisition and notices of the Court Meeting and the General Meeting, is expected to be published as soon as practicable and, in any event, within 28 days of this announcement (unless a later date is agreed with the Panel).

Comments on the Acquisition

Commenting on the Acquisition, Ian King, the Chairman of Senior, said:

"Senior's strategy is to refocus the Senior Group into a global, leading Fluid Conveyance and Thermal Management business providing IP rich, highly engineered products to customers in a range of structurally attractive end markets. The Board has full confidence that the Senior management team will continue to deliver on this strategy and will deliver on the medium-term financial targets, offering enhanced shareholder value over the medium term. However, the Board believes that BidCo's offer recognises the attractiveness of Senior and represents an opportunity for Senior shareholders to realise an immediate cash value at an attractive enterprise valuation multiple of 15.2x 2025A adjusted EBITDA.

The Board has also taken into account the Consortium's considerable experience in investing in global aerospace and industrial companies and BidCo's intentions for Senior and its employees, customers and other stakeholders."

Commenting on the Acquisition, David Squires, the Chief Executive Officer of Senior, said:

"Senior is delivering on its strategy and is firmly on track to meet the medium-term financial targets announced in March 2025. Our focus remains on serving our customers with great performance, delivering highly engineered products that fully meet their needs. I would like to recognise the exceptional contribution of my colleagues - their talent, commitment and innovation continue to drive our success. The next chapter of Senior's development will further fuel their ambition and provide new opportunities. BidCo's offer recognises the quality of Senior, our talented people, our extensive breadth of products and capabilities and our strong growth prospects. In view of the intentions set out today, the Board has confidence that BidCo is committed to the growth of the Senior business, the continued focus on satisfying our customers, and the accelerated delivery of our strategic objectives."

The Consortium commented:

"Senior is a highly regarded engineering company with compelling technical capabilities and deep, longstanding customer relationships. As long-term investors in both aerospace and industrial sectors, the Consortium has conviction in Senior and its growth potential. The breadth of our platform, coupled with significant operational expertise and access to long-term capital, puts Senior in a strong position to capitalize on the opportunities ahead."

Any decision in respect of the Acquisition (including any vote in respect of the Scheme or other response in relation to the Acquisition) should be made only on the basis of the information in the Scheme Document (or, if the Acquisition is implemented by way of a Takeover Offer, the Takeover Offer document).

This announcement has been prepared for the purpose of complying with the laws of England and Wales and the Code and the information disclosed may not be the same as that which would have been disclosed if this announcement had been prepared in accordance with the laws of jurisdictions outside England and Wales.

Senior shall prepare the Scheme Document to be distributed to Senior Shareholders. Senior and BidCo urge Senior Shareholders to read the Scheme Document when it becomes available because it shall contain important information relating to the Acquisition.

This announcement does not constitute a prospectus or prospectus exemption document.

In accordance with the Code, normal United Kingdom market practice and Rule 14e-5(b) of the US Exchange Act, Barclays and its affiliates will continue to act as exempt principal trader in Senior securities on the London Stock Exchange. These purchases and activities by exempt principal traders which are required to be made public in the United Kingdom pursuant to the Code will be reported to a Regulatory Information Service and will be available on the London Stock Exchange website at www.londonstockexchange.com. This information will also be publicly disclosed in the United States to the extent that such information is made public in the United Kingdom.

Overseas Shareholders

The release, publication or distribution of this announcement in or into jurisdictions other than the United Kingdom may be restricted by law. Persons who are not resident in the United Kingdom or who are subject to the laws of jurisdictions other than the UK (including Restricted Jurisdictions) should inform themselves of, and observe, any applicable legal or regulatory requirements.

Unless otherwise determined by BidCo or required by the Code, and permitted by applicable law and regulation, the Acquisition shall not be made available, directly or indirectly, in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction and no person may vote in favour of the Acquisition by any such use, means, instrumentality or form within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction. Accordingly, copies of this announcement and all documents relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in or into or from any Restricted Jurisdiction or any jurisdiction where to do so would violate the laws of that jurisdiction, and persons receiving this announcement and all documents relating to the Acquisition (including custodians, nominees and trustees) must not mail or otherwise distribute or send them in or into or from such jurisdictions where to do so would violate the laws in that jurisdiction. Doing so may render invalid any related purported vote in respect of the Acquisition. If the Acquisition is implemented by way of a Takeover Offer (unless otherwise permitted by applicable law and regulation), the Takeover Offer may not be made directly or indirectly, in or into, or by the use of mails or any means or instrumentality (including, but not limited to, facsimile, e-mail or other electronic transmission, telex or telephone) of interstate or foreign commerce of, or of any facility of a national, state or other securities exchange of any Restricted Jurisdiction and the Takeover Offer may not be capable of acceptance by any such use, means, instrumentality or facilities.

The availability of the Acquisition to Senior Shareholders who are not resident in the United Kingdom may be affected by the laws of the relevant jurisdictions in which they are resident. Persons who are not resident in the United Kingdom should inform themselves of, and observe, any applicable legal and regulatory requirements. In particular, the ability of persons who are not resident in the UK to vote their Scheme Shares in respect of the Scheme at the Court Meeting, or to appoint another person as proxy to vote at the Court Meeting on their behalf, may be affected by the laws of the relevant jurisdictions in which they are located. Any failure to comply with applicable restrictions may constitute a violation of securities laws in any such jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility or liability for the violation of such restrictions by any person.

The Acquisition shall be subject to the applicable requirements of the Code, the Panel, the London Stock Exchange and the Financial Conduct Authority.

Further details in relation to Senior Shareholders in overseas jurisdictions will be contained in the Scheme Document.

Additional Information for US investors

The Acquisition relates to shares of an English company and is proposed to be effected by means of a scheme of arrangement under the laws of England and Wales. A transaction effected by means of a scheme of arrangement is not subject to the tender offer rules or the proxy solicitation rules under the US Exchange Act.

Accordingly, the Scheme is subject to the disclosure and procedural requirements applicable in the United Kingdom to schemes of arrangement which differ from the disclosure requirements of United States tender offer and proxy solicitation rules.

However, if BidCo were to elect to implement the Acquisition by means of a takeover offer, such takeover offer shall be made in compliance with all applicable United States laws and regulations, including any applicable exemptions under the US Exchange Act. Such a takeover would be made in the United States by BidCo and no one else.

To the extent permitted by applicable law, in accordance with the Code, normal United Kingdom practice and pursuant to Rule 14e-5(b) of the US Exchange Act, BidCo or its nominees, or its brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase, shares or other securities of Senior outside of the US, other than pursuant to the Acquisition, until the date on which the Acquisition and/or Scheme becomes effective, lapses or is otherwise withdrawn. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases or arrangements to purchase shall be disclosed as required in the UK, shall be reported to a Regulatory Information Service and shall be available on the London Stock Exchange website at www.londonstockexchange.com.

The receipt of consideration by a US holder for the transfer of its Scheme Shares pursuant to the Scheme shall be a taxable transaction for United States federal income tax purposes. Each Senior Shareholder is urged to consult their independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to them, including under applicable United States state and local, as well as overseas and other, tax laws.

Financial information relating to Senior included in this announcement and the Scheme Document has been or shall have been prepared in accordance with accounting standards applicable in the United Kingdom and may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States.

Each of BidCo and Senior is organised under the laws of England and Wales. Some of the officers and directors of BidCo and Senior, respectively, are residents of countries other than the United States. As a result, it may be difficult for US shareholders of Senior to effect service of process within the United States upon BidCo or Senior or their respective officers or directors or to enforce against them a judgment of a US court predicated upon the federal or state securities laws of the United States. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court's jurisdiction or judgment.

Forward-looking statements

This announcement (including information incorporated by reference in this announcement), oral statements made regarding the Acquisition, and other information published by Senior, BidCo, Tinicum, Blackstone, any member of the Wider BidCo Group or any member of the Wider Senior Group may contain statements which are, or may be deemed to be, "forward-looking statements". Such forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and on numerous assumptions, valuations, targets, estimates, forecasts and projections regarding the business strategies and the environment in which Senior, BidCo or any member of the Wider BidCo Group shall operate in the future and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by those statements.

The forward-looking statements contained in this announcement relate to Senior, BidCo or any member of the Wider BidCo Group's future prospects, developments and business strategies, the expected timing and scope of the Acquisition and other statements other than historical facts. In some cases, these forward-looking statements can be identified by the use of forward-looking terminology, including the terms "believes", "estimates", "will look to", "would look to", "plans", "prepares", "anticipates", "expects", "is expected to", "is subject to", "budget", "scheduled", "forecasts", "synergy", "strategy", "goal", "cost-saving", "projects" "intends", "may", "will", "shall" or "should" or their negatives or other variations or comparable terminology. Forward-looking statements may include statements relating to the following: (i) future capital expenditures, expenses, revenues, earnings, synergies, economic performance, indebtedness, financial condition, dividend policy, losses and future prospects; (ii) business and management strategies and the expansion and growth of BidCo's, any member of the Wider BidCo Group's or Senior's operations and potential synergies resulting from the Acquisition; and (iii) the effects of global economic conditions and governmental regulation on BidCo's, any member of the Wider BidCo Group's or Senior's business.

By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that shall occur in the future. These events and circumstances include changes in the global, political, economic, business, competitive, market and regulatory forces, future exchange and interest rates, changes in tax rates, future business combinations or disposals, and any epidemic, pandemic or disease outbreak. If any one or more of these risks or uncertainties, or any other unknown or unpredictable factors, materialises or if any one or more of the assumptions prove incorrect, actual results may differ materially from those expected, estimated or projected. Such forward-looking statements should therefore be construed in the light of such factors.

Neither Senior, the Wider Senior Group, Tinicum, Blackstone, BidCo nor any member of the Wider BidCo Group, nor any of their respective associates or directors, officers or advisers, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this announcement shall actually occur. Given these risks and uncertainties, potential investors should not place any reliance on forward-looking statements.

The forward-looking statements speak only at the date of this announcement. All subsequent oral or written forward-looking statements attributable to Senior, the Wider Senior Group, Tinicum, Blackstone, BidCo or any member of the Wider BidCo Group, or any of their respective associates, directors, officers, employees or advisers, are expressly qualified in their entirety by the cautionary statement above.

Senior, the Wider Senior Group, Tinicum, Blackstone, BidCo and each member of the Wider BidCo Group expressly disclaim any obligation to update such statements other than as required by law or by the rules of any competent regulatory authority, whether as a result of new information, future events or otherwise.

No profit forecasts or estimates or quantified financial benefits statements

No statement in this announcement is intended, or is to be construed, as a profit forecast or profit estimate or quantified financial benefits statement for any period and no statement in this announcement should be interpreted to mean that earnings or earnings per share for Senior for the current or future financial years would necessarily match or exceed the historical published earnings or earnings per share for Senior.

RECOMMENDED CASH ACQUISITION

of

Senior plc ("Senior")
by

Zeus UK Bidco Limited ("BidCo")

(a newly formed company to be indirectly controlled by investment funds advised by affiliates of Tinicum Incorporated and Blackstone Inc. (the "Consortium"))

1        Introduction

The boards of BidCo and Senior are pleased to announce that they have reached agreement on the terms of a recommended cash acquisition pursuant to which BidCo shall acquire the entire issued and to be issued ordinary share capital of Senior (other than the Existing Tinicum Shares) (the "Acquisition"). The Acquisition is to be effected by means of a scheme of arrangement under Part 26 of the Companies Act.

2        The Acquisition

Under the terms of the Acquisition, which shall be subject to the Conditions and further terms set out in Appendix I to this announcement and to be set out in the Scheme Document, Scheme Shareholders shall be entitled to receive:

for each Scheme Share                                300 pence

comprising, for each Scheme Share:

o  297.85 pence in cash from BidCo (the "Cash Consideration"); and

o  the FY25 Final Dividend of 2.15 pence, which Scheme Shareholders may receive and retain, if the FY25 Final Dividend is approved by Senior Shareholders at Senior's Annual General Meeting, without any reduction to the Cash Consideration.

The Cash Consideration represents a premium of approximately:

o  36.6 per cent. to the volume-weighted average price of 218.10 pence in the six months to 26 February 2026 (being the last Business Day prior to the start of the Offer Period);

o  53.3 per cent. to the volume-weighted average price of 194.34 pence in the twelve months to 26 February 2026 (being the last Business Day prior to the start of the Offer Period); and

o  2.8 per cent. to the Closing Price per Senior Share of 289.80 pence on 2 April 2026 (being the latest practicable date prior to publication of this announcement).

The Cash Consideration values the entire issued and to be issued ordinary share capital of Senior at approximately £1,275 million on a fully diluted basis and implies an enterprise value of approximately £1,399 million (the "Implied Enterprise Value"). The Implied Enterprise Value represents a multiple of 15.2x Senior's adjusted EBITDA and 22.0x Senior's adjusted operating profit for the year ended 31 December 2025.

The Cash Consideration assumes that, other than the FY25 Final Dividend, Senior Shareholders shall not receive any dividend, distribution or other return of value.

If, on or after the date of this announcement and on or prior to the Effective Date, and other than the FY25 Final Dividend, any dividend, distribution or other return of value is declared, made, or paid or becomes payable by Senior, BidCo reserves the right to reduce the Cash Consideration by an amount up to the amount of such dividend, distribution or other return of value, in which case references to the Cash Consideration shall be deemed to be a reference to the Cash Consideration as so reduced. In such circumstances, Senior Shareholders shall be entitled to retain any such dividend, distribution or other return of value declared, made, or paid.

It is expected that the Scheme Document, containing further information about the Acquisition and notices of the Court Meeting and the General Meeting, together with Forms of Proxy, shall be published as soon as reasonably practicable and, in any event, within 28 days of this announcement (unless a later date is agreed with the Panel).

Subject to the satisfaction or waiver of the Conditions set out in Appendix I to this announcement, and the full terms and conditions which shall be set out in the Scheme Document, and subject to the approval and availability of the Court, it is expected that the Scheme shall become effective by the end of Q1 2027.

3        Background to and reasons for the Acquisition

The Consortium believes that Senior is a high-quality engineering business with strong positions in attractive end markets, longstanding customer relationships and the potential for significant opportunities for further operational and strategic development best facilitated under committed private ownership. In evaluating the Acquisition, the Consortium has been attracted not only by the quality of the business, but also by the degree to which Senior aligns with the Consortium's established history of investing in, supporting and improving highly engineered aerospace and industrial components companies. The Consortium believes that this experience is directly relevant to Senior and its end markets and would assist the Consortium in supporting the continued development of the business.

Within the Consortium, Tinicum brings highly relevant and complementary industrial and aerospace experience, including through AeroFlow Technologies and other engineered products investments, while Blackstone contributes substantial experience investing in, scaling and supporting complex industrial businesses through active ownership, strategic development and disciplined execution, in addition to its scale and financial resources. The Consortium believes that this combination creates a compelling ownership framework for Senior and provides a strong basis for execution, long-term support and responsible stewardship.

The Consortium's investment activity in the aerospace components sector has reinforced its conviction in the attractiveness of these markets and in the value of active, long-term industrial ownership. The Consortium's most recent aerospace investment was the acquisition of TriMas Aerospace, which has been combined with PennAero to form a leading manufacturer of aerospace fasteners and related specialty components.

A key element of the Consortium's rationale for the Acquisition is Tinicum's ownership of AeroFlow Technologies, which was created through the acquisition of Leggett & Platt's Aerospace Products Group and has since expanded through the acquisitions of G&L Tube and Evans Alloys. AeroFlow Technologies' capabilities, together with its operations across the United States, the United Kingdom and France, provide the Consortium with relevant complementary aerospace experience and familiarity that it believes would be helpful in supporting the long-term development of Senior. The Consortium shall place Senior and AeroFlow Technologies under common ownership as part of the Acquisition and believes that this would represent a complementary addition to the broader investment case for Senior, providing additional adjacent aerospace exposure and earnings resilience.

In the Consortium's view, its broader sector footprint, active operating engagement and experience across aerospace programmes would support Senior in strengthening its customer relationships, deepening industry connectivity, reinforcing its strategic relevance and enhancing the overall strength of the combined platform's customer offering.

Attracting and retaining talent is another important element of the Consortium's transaction rationale. The Consortium believes that companies within its portfolio are regarded as employers of choice in the highly competitive aerospace manufacturing market. The Consortium believes that this would provide Senior with access to a deeper pool of skilled talent in certain of its important production facilities and, over time, support the attraction, development and retention of talent in parts of the combined platform where labour availability and specialised technical capability are particularly important.

The Consortium believes that Senior would be best supported under private ownership, which would provide greater flexibility to pursue targeted organic and inorganic growth opportunities without public market expectations and requirements. In the Consortium's view, this ownership model would enable Senior to take a disciplined and long-term approach to capital allocation, including investing in growth initiatives, supporting innovation and R&D, pursuing selective acquisitions where strategically and financially attractive, and optimising the portfolio and cost structure in a flexible and disciplined manner. More broadly, the Consortium operates with a longer investment horizon than traditional private equity and believes that, unconstrained by a fixed exit timetable, this approach is well suited to supporting Senior's long-term industrial development and value creation.

Overall, the Consortium believes that the Acquisition represents an attractive opportunity to combine a high-quality UK-listed engineering business with committed long-term ownership, relevant sector expertise and significant capital resources, with a view to delivering sustainable long-term value creation.

4        Recommendation

The Senior Directors, who have been so advised by Lazard as to the financial terms of the Acquisition, consider the terms of the Acquisition to be fair and reasonable. In providing its advice to the Senior Directors, Lazard has taken into account the commercial assessments of the Senior Directors. Lazard is providing independent financial advice to the Senior Directors for the purposes of Rule 3 of the Code.

Accordingly, the Senior Directors intend to recommend unanimously that Senior Shareholders vote in favour of the Scheme at the Court Meeting and the resolutions to be proposed at the General Meeting as the Senior Directors have irrevocably undertaken to do in respect of their own beneficial holdings of Senior Shares representing, in aggregate, approximately 0.6 per cent. of the ordinary share capital of Senior, and approximately 0.6 per cent. of the Scheme Shares, in each case in issue on 2 April 2026 (being the latest practicable date prior to this announcement).

5        Irrevocable undertakings

BidCo has received irrevocable undertakings from each of the Senior Directors to vote in favour (or procure a vote in favour) of the Scheme at the Court Meeting and the resolutions to be proposed at the General Meeting, in respect of their own beneficial holdings of Senior Shares amounting, in aggregate, to a total of 2,620,740 Senior Shares, representing approximately 0.6 per cent. of the ordinary share capital of Senior, and approximately 0.6 per cent. of the Scheme Shares, in each case in issue on 2 April 2026 (being the latest practicable date prior to this announcement).

BidCo has also received an irrevocable undertaking to vote in favour of the Scheme at the Court Meeting and the resolutions to be proposed at the General Meeting from Alantra in respect of a total of 72,307,009 Senior Shares representing, in aggregate, approximately 17.2 per cent. of Senior's ordinary share capital, and approximately 17.7 per cent. of the Scheme Shares, in each case in issue on 2 April 2026 (being the latest practicable date prior to this announcement).

BidCo has therefore received irrevocable undertakings in respect of a total of 74,927,749 Scheme Shares representing, in aggregate, approximately 17.9 per cent. of Senior's ordinary share capital, and approximately 18.3 per cent. of the Scheme Shares, in each case in issue on 2 April 2026 (being the latest practicable date prior to this announcement).

Further details of these irrevocable undertakings (including the circumstances in which they shall fall away) are set out in Appendix III to this announcement.

6        Background to and reasons for the recommendation

Senior today: A leading Fluid Conveyance and Thermal Management business

Over recent years, Senior has delivered consistent operational and financial progress, reflecting sustained execution of its stated strategy. 2025 marked a pivotal year for Senior, with the successful divestment of its Aerostructures business, thereby positioning Senior as a global, leading Fluid Conveyance and Thermal Management ("FCTM") business. Under the FCTM strategy, Senior supplies highly engineered products and systems with differentiated capabilities, supported by design-rich intellectual property and technical expertise. Harnessing its technical capabilities and established cost competitive global footprint of 19 operating businesses in 10 countries, Senior has built deep customer relationships in attractive and structurally resilient end markets.

The business is ideally positioned to benefit from longer term industry megatrends across its Aerospace and Flexonics divisions, notably growth in air travel, increased defence spending, energy consumption growth, electrification and digitalisation. All of these trends provide Senior with confidence that it is optimally placed to meet market needs and deliver long term value creation for shareholders.

The strong execution of Senior's strategy was demonstrated by its strong financial and operational performance delivered for the financial year to 31 December 2025, with revenue up 6% to £738.2 million and adjusted profit before tax up 24% to £51.2 million, both on a constant currency basis, driven in particular by an improvement in the Aerospace division. Through its focus on disciplined capital allocation, the business also delivered good progress on ROCE, which increased by 140bps to 13.1%, benefitting from both the disposal of Aerostructures and adjusted operating profit growth.

Senior delivered excellent operating cashflow conversion of 90% in 2025. This, together with the proceeds from the disposal of Aerostructures, resulted in a reduction in year-end leverage (net debt to EBITDA) to 0.9x. The balance sheet was further de-risked in 2025 through the successful completion of a buy-in transaction for the closed UK defined benefit pension plan.

Performance in 2025 also demonstrated good progress against the delivery of the Senior Group's medium-term targets as set out at the 2025 Investor Day, namely:

·      at least double-digit group adjusted operating margins:

o  at least mid-teens operating margins in the Aerospace division; and

o  10-12% operating margins in the Flexonics division;

·      cash conversion of greater than 85% through the cycle; and

·      ROCE of 15-20%.

These targets are supported by an expectation of mid-single digit organic growth through-the-cycle and are underpinned by a strong balance sheet, with leverage of between 0.5x and 1.5x. 

On 2 March 2026, the Senior Board reconfirmed its expectations for the 2026 outlook. It remains confident in delivering enhanced shareholder value as it executes on its strategy and continues to strengthen its financial performance in line with its medium-term financial targets.

Proposal from Advent and subsequent engagement with other potential offerors, including BidCo

Shortly after announcing the completion of the divestment of the Aerostructures business at the end of 2025, the Senior Board received an unsolicited, non-binding all-cash offer from Advent International ("Advent") in January 2026 and two further proposals from Advent in February 2026. Given the strong prospects for the Senior Group, the Senior Board unanimously rejected these proposals, the highest of which set out the terms of an all-cash offer at 272 pence per Senior Share, on the grounds that the proposals undervalued Senior and its future prospects.

However, mindful of its fiduciary obligations to consider all options for maximising shareholder value, during the period of Advent's approaches in January and February 2026, the Senior Board appointed Lazard and Jefferies to initiate discussions with a limited number of other third parties regarding a possible offer for the entire issued and to be issued share capital of Senior, to determine the value that could potentially be achieved. Following a period of discussions with these other parties, the Senior Board received further, superior all-cash proposals from two other potential offerors, BidCo and Arcline Investment Management ("Arcline").

The Senior Board continued discussions with a number of potential offerors and provided access to confirmatory due diligence materials in order to assist BidCo, Advent and Arcline in their understanding and assessment of Senior with a view to determining the maximum value that could potentially be achieved. The highest of the proposals was received from BidCo at 297.85 pence per Senior Share and the right to retain the FY25 Final Dividend, on terms which the Senior Board intends to unanimously recommend to Senior Shareholders.

In considering the financial terms of the Acquisition and determining whether they reflect an appropriate valuation of Senior and its future prospects, the Senior Board took into account a number of factors, including that:

·   the Acquisition reflects the strength of Senior's business and its future prospects, and provides an opportunity for Senior Shareholders to crystallise, in cash, the value of their investments at a fair and reasonable value; and

·      the Cash Consideration represents:

o  a multiple of approximately:

§ 15.2x Senior's adjusted EBITDA for the year ended 31 December 2025; and

§ 22.0x Senior's adjusted operating profit for the year ended 31 December 2025; and

o  a premium of approximately:

§ 36.6 per cent. to the volume-weighted average price of 218.10 pence in the six months to 26 February 2026 (being the last Business Day prior to the start of the Offer Period);

§ 53.3 per cent. to the volume-weighted average price of 194.34 pence in the twelve months to 26 February 2026 (being the last Business Day prior to the start of the Offer Period); and

§ 2.8 per cent. to the Closing Price per Senior Share of 289.80 pence on 2 April 2026 (being the latest practicable date prior to publication of this announcement).

Accordingly, while the Senior Board remains confident in its ability to deliver sustainable value for Senior Shareholders, the Senior Directors believe that the Acquisition represents an attractive opportunity for Senior Shareholders to realise an immediate and certain cash value for their investment, relative to a longer period to potentially realise this value as an independent public company.

In considering the Acquisition, the Board has taken into account BidCo's stated intentions for the business, including BidCo's intention to place Senior and AeroFlow Technologies under common ownership and BidCo's intentions for Senior's employees, customers and other stakeholders, as set out in paragraph 9.

Following careful consideration of the financial terms of the Acquisition, the combination of value and certainty that the terms of the Acquisition provides to Senior Shareholders, and the above factors, the Senior Directors intend to unanimously recommend that Senior Shareholders vote in favour of the Scheme at the Court Meeting and the resolutions to be proposed at the General Meeting, as the Senior Directors who hold Senior Shares have irrevocably undertaken to do in respect of their own beneficial holdings of Senior Shares, amounting in aggregate to 2,620,740 Senior Shares representing approximately 0.6 per cent. of the share capital of Senior, and approximately 0.6 per cent. of the Scheme Shares, in each case in issue on 2 April 2026 (being the latest practicable date prior to this announcement).

9        Intentions of BidCo

As set out in paragraph 3, BidCo believes that the Acquisition represents an attractive opportunity to support a high-quality UK-headquartered engineering business with committed long-term ownership, deep sector expertise and significant capital resources, with a view to delivering sustainable long-term value creation. Consistent with that strategy, BidCo shall place Senior and AeroFlow Technologies under common ownership and intends to work with the Senior and AeroFlow Technologies teams to undertake a detailed evaluation of how best to coordinate and, where appropriate, integrate certain aspects of their businesses and operations over time to enable the combined platform to offer a varied set of offerings to support its customers.

Prior to this announcement, BidCo has been granted access to Senior's senior management for confirmatory due diligence. Accordingly, BidCo has developed a preliminary strategy for Senior following the Acquisition, as reflected below. That strategy is based on BidCo's belief that Senior would benefit from committed long-term ownership, deep industrial and aerospace expertise and the opportunity to broaden its capabilities and customer offering over time, including as may arise through AeroFlow Technologies and Senior becoming a combined platform. BidCo believes this would provide complementary adjacent aerospace exposure and additional earnings resilience, whilst strengthening customer relationships through increased relevance across customer programmes, a broader sector footprint and deeper operating engagement.

Following the Acquisition becoming Effective, BidCo intends to expand upon the work already conducted by undertaking, together with the Senior and AeroFlow Technologies teams where appropriate, a detailed evaluation of the business, operations, and organisational structure of Senior and AeroFlow Technologies in order to determine how best to support the long-term development of Senior and the broader combined platform. BidCo intends that this evaluation and the development of an implementation plan (the "Implementation Plan") will be completed within approximately 6 months of the Effective Date, and will focus on:

·     an assessment of the performance, short and long-term objectives, strategy, market position, strategic alignment and long-term potential of Senior's divisions and the businesses within them;

·     considering how best to position Senior's businesses for greater competitive strength over the longer term, and continuing the optimisation of Senior that Senior's management team has been undertaking over the past few years, which would include evaluating the best corporate organisational set up for Senior in a private context to maximise potential and create value;

·     a review of capital allocation frameworks with a view to increasing investment for growth and how best to position the business to compete for greater market share;

·      engaging with the key stakeholders, including employees and customers;

·  consideration of operational improvement opportunities across the global supply chain and manufacturing footprint;

·     assessing areas of complementary product capability and engineering know-how between Senior and AeroFlow Technologies;

·   identifying opportunities to broaden the combined platform's technical capabilities and customer offering over time; and

·      assessing Senior's existing research and development and identifying areas of expertise.

Employees and management

BidCo attaches great importance to the skill and experience of Senior's management and employees and considers them key to the success of Senior. BidCo, under committed long-term private ownership, intends to provide ongoing investment to grow the business, and believes that Senior's employees will benefit from opportunities to support the continued development of the business over the longer term.

BidCo intends to undertake a review of Senior's employee base to determine if any material headcount reductions will be necessary as part of the development of the Implementation Plan. Subject to applicable employee information and consultation requirements, any operational and administrative efficiencies may involve headcount reduction, though BidCo does not intend for these to be material. Additionally, following the delisting of Senior Shares and re-registration of Senior as a private limited company (as further described in paragraph 15 below), a limited number of listed company-related functions are intended to be reduced in scope.

The detailed steps for any intended headcount reductions are subject to the post Effective Date review referred to above and would also be subject to comprehensive and detailed planning, appropriate engagement and consultation with representatives and other stakeholders, including affected employees and any appropriate employee representative bodies in accordance with BidCo's legal obligations.

Save as set out above, BidCo does not intend for there to be any material change in the balance of skills and functions of employees and management in Senior to arise as a consequence of the Acquisition. Where any roles are impacted, BidCo will comply with applicable law, including any information and consultation obligations.

It is also intended that, upon the Acquisition becoming Effective, each of the non-executive members of the Senior Board shall resign from their office as a director of Senior.

Existing rights and pension schemes

Following the Acquisition becoming Effective, the existing employment rights, including pension rights, of the management and employees of Senior shall be fully safeguarded in accordance with applicable law. BidCo's plans for Senior do not involve any material change in the employment rights of, or in the conditions of employment of, Senior employees, unless otherwise agreed with the relevant employee.

Senior operates funded defined benefit pension schemes in the UK and the US, an unfunded defined benefit arrangement in Germany, unfunded closed pension and post-retirement healthcare plans in the US, a provision for post-retirement payments in France, and defined contribution pension schemes in the UK and the US.

The Senior US defined benefit pension scheme is currently closed to the admission of new members and to the future accrual of benefits for existing members. BidCo intends that the current employer contributions for the funding of the Senior US defined benefit pension scheme shall continue on their current terms without change until the next actuarial valuation of this scheme is obtained by the trustees. It is not intended that any changes shall be made to reopen this scheme to the admission of new members.

The Senior UK defined benefit pension scheme is currently closed to the admission of new members and to the future accrual of benefits for existing members. The benefits of all members of the UK defined benefit scheme were bought-in with an insurance company in 2025, and no contributions are currently payable. It is not intended that any changes shall be made to reopen this scheme to the admission of new members or to the future accrual of benefits.

Locations, headquarters, headquarter functions, and research and development

BidCo has no intentions to change the location of Senior's headquarters, headquarter functions (other than listed company-related functions) or places of business and has no intentions for any material redeployment of Senior's fixed assets.

BidCo understands the importance of R&D to Senior and its businesses and has no intentions to reduce Senior's investment in R&D functions or to make any material changes in the nature of those functions.

Trading facilities

Senior is currently listed on the Official List and, as set out in paragraph 15 below, a request shall be made to the London Stock Exchange to cancel trading in Senior Shares and de-list Senior from the Official List and re-register it as a private company as soon as practicable following the Effective Date.

No statements in this paragraph 9 constitute "post-offer undertakings" for the purposes of Rule 19.5 of the Code.

10      Arrangements between BidCo and Senior management

BidCo has not entered into, and has not discussed any form of, incentivisation arrangements with members of Senior's management or senior employees of Senior, and has no plans to do so prior to the Acquisition becoming Effective. Following the Acquisition becoming Effective, BidCo intends to put in place customary incentivisation arrangements as appropriate for the management and senior employees of Senior.

11      Senior Share Plans

Participants in the Senior Share Plans shall be contacted regarding the effect of the Acquisition on their rights under the Senior Share Plans and appropriate proposals shall be made to such participants in due course.

Details of the impact of the Scheme on each of the Senior Share Plans and the terms of such proposals shall be set out in the Scheme Document and in separate letters to be sent to participants in the Senior Share Plans.

12      Financing

BidCo is providing the cash consideration payable under the Acquisition through a mix of equity to be drawn from the Consortium (which is expected to include a passive minority co-investment by Cliffwater LLC ("Cliffwater")) and invested indirectly in BidCo and from a new credit facility that has been arranged by Barclays. In addition, other potential investors may acquire indirect minority interests in BidCo during the Offer Period or after the Effective Date.

Barclays, as financial adviser to BidCo, is satisfied that sufficient resources are available to BidCo to satisfy in full the cash consideration payable to Senior Shareholders under the terms of the Acquisition.

BidCo has agreed to use all reasonable endeavours to obtain the Regulatory Clearances (including which relate to Blackstone acquiring an indirect interest in AeroFlow Technologies). The Co-operation Agreement also records the intention of BidCo and Senior to implement the Acquisition by way of the Scheme, subject to BidCo having the right to implement the Acquisition by way of a Takeover Offer in certain circumstances and in compliance with the Code. BidCo and Senior have further agreed to certain customary provisions in the event that BidCo exercises its right to switch to a Takeover Offer.

The Co-operation Agreement will be capable of termination in certain circumstances, including:

(i)         if BidCo and Senior so agree in writing;

(ii)     if a competing offer for Senior completes, becomes effective or is declared unconditional in all respects;

(iii)   upon service of written notice by BidCo to Senior, if the Senior Directors withdraw their recommendation of the Acquisition and there is no subsequent recommendation of the Senior Directors to the Scheme Shareholders to vote in favour of the Scheme (or to accept the Takeover Offer, if the Scheme should switch to a Takeover Offer) prior to the service of such notice; or

(iv)      upon service of written notice by BidCo to Senior or Senior to BidCo, if the Effective Date has not occurred by the Long-stop Date, unless otherwise agreed between BidCo and Senior in writing or required by the Panel.

Clean Team Agreement

Tinicum, Senior and Blackstone entered into a clean team agreement (the "Clean Team Agreement") on 3 March 2026 which set out, among other things, certain procedures and principles to be followed to ensure adequate treatment of certain commercially sensitive confidential information between Senior and the Consortium's clean team individuals and/or external advisers.

Joint Defence Agreement

BidCo and Senior have put in place a confidentiality and joint defence agreement on 10 March 2026 (the "Joint Defence Agreement"), which sets out how confidential information that is commercially sensitive can be disclosed, used or shared between BidCo's external legal counsel and/or economists and Senior's external legal counsel and/or economists for the purposes of obtaining the consent of competition authorities and/or regulatory clearances in connection with the Acquisition.

Bid Conduct Agreement

14      Structure of and Conditions to the Acquisition

It is intended that the Acquisition shall be effected by means of a Court-approved scheme of arrangement under Part 26 of the Companies Act, although BidCo reserves the right to implement the Acquisition by means of a Takeover Offer (subject to Panel consent and the terms of the Co-operation Agreement).

The purpose of the Scheme is to provide for BidCo to become the holder of the entire issued and to be issued ordinary share capital of Senior not already directly or indirectly owned by it. This is to be achieved by the transfer of Scheme Shares to BidCo, in consideration for which Scheme Shareholders shall receive cash consideration on the basis set out in paragraph 2 of this announcement.

The Existing Tinicum Shares will not be Scheme Shares and will not be acquired by BidCo pursuant to the Acquisition, but will be acquired by BidCo on or as soon as practicable after the Effective Date. Tinicum will not be permitted to vote such Senior Shares at the Court Meeting, but will be permitted to vote such Senior Shares at the General Meeting.

The Acquisition shall be subject to the Conditions and further terms set out below and in Appendix I to this announcement, and to the full terms and conditions to be set out in the Scheme Document and shall only become effective, if, among other things, the following events occur on or before 11.59 p.m. on the Long-stop Date:

(i)         the approval of the Scheme by a majority in number of Scheme Shareholders who are present and vote, whether in person or by proxy, at the Court Meeting and who represent 75 per cent. in value of Scheme Shares validly voted by those Scheme Shareholders;

(ii)     the resolutions required to approve and implement the Scheme being duly passed by Senior Shareholders representing the requisite majority or majorities of votes cast at the General Meeting;

(iii)      the approval of the Scheme by the Court (with or without modification but subject to any modification being on terms acceptable to Senior and BidCo);

(iv)       the delivery of a copy of the Court Order to the Registrar of Companies; and

(v)        the satisfaction or waiver of the Regulatory Clearances.

Given the material significance of common ownership of Senior and AeroFlow Technologies to the Consortium's strategic rationale for the Acquisition, Senior Shareholders should be aware that certain of the Conditions set out in paragraph 3 of Part A of Appendix I relate to Blackstone acquiring an indirect interest in AeroFlow Technologies and if such Conditions are not satisfied, it would be BidCo's intention to seek the Panel's consent to invoke such Condition(s) to cause the Acquisition to lapse.

The Scheme shall lapse if:

·           the Court Meeting and the General Meeting are not held by the 22^nd day after the expected date of such meetings, to be set out in the Scheme Document in due course (or such later date as may be agreed between BidCo and Senior);

·            the Court Hearing is not held by the 22^nd day after the expected date of such hearing to be set out in the Scheme Document in due course (or such later date as may be agreed between BidCo and Senior); or

·            the Scheme does not become effective by no later than 11.59 p.m. on the Long-stop Date,

provided, however, that the deadlines for the timing of the Court Meeting, the General Meeting and the Court Hearing as set out above may be waived by BidCo, and the deadline for the Scheme to become effective may be extended by agreement between Senior and BidCo.

Subject to satisfaction (or waiver, where applicable) of all relevant conditions, including the Conditions and further terms set out below and in Appendix I to this announcement and the full terms and conditions to be set out in the Scheme Document, the Scheme is expected to become effective by the end of Q1 2027.

Upon the Scheme becoming effective, it shall be binding on all Scheme Shareholders, irrespective of whether or not they attended or voted at the Court Meeting or the General Meeting.

Further details of the Scheme, including an expected timetable of principal events relating to the Acquisition, shall be set out in the Scheme Document. The Scheme Document, containing further information about the Acquisition and notices of the Court Meeting and the General Meeting, together with Forms of Proxy, is expected to be published as soon as reasonably practicable and, in any event, within 28 days of this announcement (unless a later date is agreed with the Panel).

The Scheme will be governed by English law and will be subject to the jurisdiction of the Court. The Scheme will be subject to the applicable requirements of the Code, the Panel, the London Stock Exchange, the FCA, the Listing Rules, the Court and the Registrar of Companies.

15      De-listing and re-registration

Prior to the Scheme becoming effective, Senior shall make an application for the cancellation of trading of Senior Shares on the Main Market and for the cancellation of the listing of Senior Shares on the Official List, in each case to take effect on or shortly after the Effective Date. The last day of dealings in Senior Shares on the Main Market is expected to be the Business Day immediately prior to the Effective Date and no transfers shall be registered after 6.00 p.m. on that date.

On the Effective Date, share certificates in respect of Senior Shares shall cease to be valid and entitlements to Senior Shares held within the CREST system shall be cancelled.

It is also proposed that, following the Effective Date and after its shares are delisted, Senior shall be re-registered as a private limited company.

16      Dividends

If the FY25 Final Dividend is approved by Senior Shareholders at Senior's Annual General Meeting, the Scheme Shareholders may receive and retain the FY25 Final Dividend without any reduction to the Cash Consideration. 

The Cash Consideration assumes that, other than the FY25 Final Dividend, Senior Shareholders shall not receive any dividend, distribution or other return of value. If, on or after the date of this announcement and on or prior to the Effective Date, and other than the FY25 Final Dividend, any dividend, distribution or other return of value is declared, made, or paid, or becomes payable by Senior, BidCo reserves the right to reduce the Cash Consideration by an amount up to the amount of such dividend, distribution or other return of value in which case references to the Cash Consideration will be deemed to be a reference to the Cash Consideration as so reduced. In such circumstances, Senior Shareholders shall be entitled to retain any such dividend, distribution or other return of value declared, made, or paid.

17      Disclosure of Interests in Senior

Save in respect of the irrevocable undertakings referred to in paragraph 5 above and as disclosed below, as at the close of business on 2 April 2026 (being the last practicable date prior to the date of this announcement) neither BidCo, nor any of its directors, nor, so far as BidCo is aware, any person acting in concert (within the meaning of the Code) with it has either:

(i) any interest in or right to subscribe for any relevant securities of Senior;

(ii) any short positions in respect of relevant Senior Shares (whether conditional or absolute and whether in the money or otherwise), including any short position under a derivative, any agreement to sell or any delivery obligation or right to require another person to purchase or take delivery;

(iii) any Dealing Arrangement, in relation to Senior Shares or in relation to any securities convertible or exchangeable into Senior Shares; nor

(iv) borrowed or lent any relevant Senior Shares (including, for these purposes, any financial collateral arrangements of the kind referred to in Note 3 on Rule 4.6 of the Code), save for any borrowed shares which had been either on-lent or sold:

'Interests in securities' for these purposes arise, in summary, when a person has long economic exposure, whether absolute or conditional, to changes in the price of securities (and a person who only has a short position in securities is not treated as interested in those securities). In particular, a person shall be treated as having an 'interest' by virtue of the ownership, voting rights or control of securities, or by virtue of any agreement to purchase, option in respect of, or derivative referenced to, securities.

18      General

BidCo reserves the right to elect (with the consent of the Panel, and subject to the terms of the Co-operation Agreement) to implement the Acquisition by way of a Takeover Offer for the Senior Shares (other than the Existing Tinicum Shares or any Senior Shares already held by BidCo) as an alternative to the Scheme. In such event, the Takeover Offer shall be implemented on the same terms, so far as applicable, and subject to the terms of the Co-operation Agreement, as those which would apply to the Scheme, subject to appropriate amendments to reflect the change in method of effecting the Acquisition, including (without limitation) if required by the Co-operation Agreement, an acceptance condition set at no more than seventy-five (75) per cent. of Senior Shares or such lesser percentage (being more than fifty (50) per cent.) of Senior Shares as BidCo may decide (subject to the consent of the Panel to the extent necessary).

If the Offer is effected by way of a Takeover Offer and such Takeover Offer becomes or is declared unconditional and sufficient acceptances are received, BidCo intends to: (i) make a request to the FCA to cancel the listing of the Senior Shares from the Official List; (ii) make a request to the London Stock Exchange to cancel trading in Senior Shares on its market for listed securities; and (iii) exercise its rights to apply the provisions of Chapter 3 of Part 28 of the Companies Act to acquire compulsorily the remaining Senior Shares in respect of which the Takeover Offer has not been accepted.

The Acquisition shall be made subject to the Conditions and further terms set out in Appendix I to this announcement and the full terms and conditions to be set out in the Scheme Document.

The bases and sources of certain financial information contained in this announcement are set out in Appendix II to this announcement. A summary of the irrevocable undertakings given in relation to the Acquisition is contained in Appendix III to this announcement. Certain terms used in this announcement are defined in Appendix IV to this announcement.

It is expected that the Scheme Document and the Forms of Proxy accompanying the Scheme Document shall be published as soon as practicable and, in any event, within 28 days of this announcement (unless a later date is agreed with the Panel). The Scheme Document and Forms of Proxy shall be made available to all Senior Shareholders at no charge to them.

Barclays, Lazard, Jefferies, BMO and Deutsche Numis have each given and not withdrawn their consent to the publication of this announcement with the inclusion herein of the references to their names in the form and context in which they appear.

19      Documents available on website

Copies of the following documents shall be made available on BidCo's and Senior's websites at https://www.tinicum.com/, https://publishdocuments.co.uk/ and https://www.seniorplc.com respectively, promptly and by no later than 12 noon on the Business Day following the date of this announcement, subject to certain restrictions relating to persons residing in Restricted Jurisdictions until the end of the Offer Period:

Further Information

This announcement is for information purposes only and is not intended to and does not constitute or form part of any offer to sell or invitation to purchase or subscribe for any securities or the solicitation of an offer to buy any securities, pursuant to the Acquisition or otherwise.

The Acquisition shall be made solely by means of the Scheme Document (or, if the Acquisition is implemented by way of a Takeover Offer, the Takeover Offer document) which, together with the Forms of Proxy, shall contain the full terms and conditions of the Acquisition, including details of how to vote in respect of the Acquisition. Any decision in respect of the Acquisition (including any vote in respect of the Scheme or other response in relation to the Acquisition) should be made only on the basis of the information in the Scheme Document (or, if the Acquisition is implemented by way of a Takeover Offer, the Takeover Offer document).

This announcement has been prepared for the purpose of complying with the laws of England and Wales and the Code and the information disclosed may not be the same as that which would have been disclosed if this announcement had been prepared in accordance with the laws of jurisdictions outside England and Wales.

Senior shall prepare the Scheme Document to be distributed to Senior Shareholders. Senior and BidCo urge Senior Shareholders to read the Scheme Document when it becomes available because it shall contain important information relating to the Acquisition.

This announcement does not constitute a prospectus or prospectus exemption document.

In accordance with the Code, normal United Kingdom market practice and Rule 14e-5(b) of the US Exchange Act, Barclays and its affiliates will continue to act as exempt principal trader in Senior securities on the London Stock Exchange. These purchases and activities by exempt principal traders which are required to be made public in the United Kingdom pursuant to the Code will be reported to a Regulatory Information Service and will be available on the London Stock Exchange website at www.londonstockexchange.com. This information will also be publicly disclosed in the United States to the extent that such information is made public in the United Kingdom.

Overseas Shareholders

The release, publication or distribution of this announcement in or into jurisdictions other than the United Kingdom may be restricted by law. Persons who are not resident in the United Kingdom or who are subject to the laws of jurisdictions other than the UK (including Restricted Jurisdictions) should inform themselves of, and observe, any applicable legal or regulatory requirements.

Unless otherwise determined by BidCo or required by the Code, and permitted by applicable law and regulation, the Acquisition shall not be made available, directly or indirectly, in, into or from a Restricted Jurisdiction where to do so would violate the laws in that jurisdiction and no person may vote in favour of the Acquisition by any such use, means, instrumentality or form within a Restricted Jurisdiction or any other jurisdiction if to do so would constitute a violation of the laws of that jurisdiction. Accordingly, copies of this announcement and all documents relating to the Acquisition are not being, and must not be, directly or indirectly, mailed or otherwise forwarded, distributed or sent in or into or from any Restricted Jurisdiction or any jurisdiction where to do so would violate the laws of that jurisdiction, and persons receiving this announcement and all documents relating to the Acquisition (including custodians, nominees and trustees) must not mail or otherwise distribute or send them in or into or from such jurisdictions where to do so would violate the laws in that jurisdiction. Doing so may render invalid any related purported vote in respect of the Acquisition. If the Acquisition is implemented by way of a Takeover Offer (unless otherwise permitted by applicable law and regulation), the Takeover Offer may not be made directly or indirectly, in or into, or by the use of mails or any means or instrumentality (including, but not limited to, facsimile, e-mail or other electronic transmission, telex or telephone) of interstate or foreign commerce of, or of any facility of a national, state or other securities exchange of any Restricted Jurisdiction and the Takeover Offer may not be capable of acceptance by any such use, means, instrumentality or facilities.

The availability of the Acquisition to Senior Shareholders who are not resident in the United Kingdom may be affected by the laws of the relevant jurisdictions in which they are resident. Persons who are not resident in the United Kingdom should inform themselves of, and observe, any applicable legal and regulatory requirements. In particular, the ability of persons who are not resident in the UK to vote their Scheme Shares in respect of the Scheme at the Court Meeting, or to appoint another person as proxy to vote at the Court Meeting on their behalf, may be affected by the laws of the relevant jurisdictions in which they are located. Any failure to comply with applicable restrictions may constitute a violation of securities laws in any such jurisdiction. To the fullest extent permitted by applicable law, the companies and persons involved in the Acquisition disclaim any responsibility or liability for the violation of such restrictions by any person.

Further details in relation to Senior Shareholders in overseas jurisdictions will be contained in the Scheme Document.

Additional Information for US investors

The Acquisition relates to shares of a UK company and is proposed to be effected by means of a scheme of arrangement under the laws of England and Wales. A transaction effected by means of a scheme of arrangement is not subject to the tender offer rules or the proxy solicitation rules under the US Exchange Act.

Accordingly, the Acquisition is subject to the disclosure and procedural requirements applicable in the United Kingdom to schemes of arrangement which differ from the disclosure requirements of United States tender offer and proxy solicitation rules.

However, if BidCo were to elect to implement the Acquisition by means of a takeover offer, such takeover offer shall be made in compliance with all applicable United States laws and regulations, including any applicable exemptions under the US Exchange Act. Such a takeover would be made in the United States by BidCo and no one else.

To the extent permitted by applicable law, in accordance with the Code, normal United Kingdom practice and pursuant to Rule 14e-5(b) of the US Exchange Act, BidCo or its nominees, or its brokers (acting as agents), may from time to time make certain purchases of, or arrangements to purchase, shares or other securities of Senior outside of the US, other than pursuant to the Acquisition, until the date on which the Acquisition and/or Scheme becomes effective, lapses or is otherwise withdrawn. These purchases may occur either in the open market at prevailing prices or in private transactions at negotiated prices. Any information about such purchases or arrangements to purchase shall be disclosed as required in the UK, shall be reported to a Regulatory Information Service and shall be available on the London Stock Exchange website atwww.londonstockexchange.com.

The receipt of consideration by a US holder for the transfer of its Scheme Shares pursuant to the Scheme shall be a taxable transaction for United States federal income tax purposes. Each Senior Shareholder is urged to consult their independent professional adviser immediately regarding the tax consequences of the Acquisition applicable to them, including under applicable United States state and local, as well as overseas and other, tax laws.

Financial information relating to Senior included in this announcement and the Scheme Document has been or shall have been prepared in accordance with accounting standards applicable in the United Kingdom and may not be comparable to financial information of US companies or companies whose financial statements are prepared in accordance with generally accepted accounting principles in the United States.

Each of BidCo and Senior is organised under the laws of England and Wales. Some of the officers and directors of BidCo and Senior, respectively, are residents of countries other than the United States. As a result, it may be difficult for US shareholders of Senior to effect service of process within the United States upon BidCo or Senior or their respective officers or directors or to enforce against them a judgment of a US court predicated upon the federal or state securities laws of the United States. Further, it may be difficult to compel a non-US company and its affiliates to subject themselves to a US court's jurisdiction or judgment.

Forward-looking statements

This announcement (including information incorporated by reference in this announcement), oral statements made regarding the Acquisition, and other information published by Senior, BidCo, Tinicum, Blackstone, any member of the Wider BidCo Group or any member of the Wider Senior Group may contain statements which are, or may be deemed to be, "forward-looking statements". Such forward-looking statements are prospective in nature and are not based on historical facts, but rather on current expectations and on numerous assumptions, valuations, targets, estimates, forecasts and projections regarding the business strategies and the environment in which Senior, BidCo or any member of the Wider BidCo Group shall operate in the future and are subject to risks and uncertainties that could cause actual results to differ materially from those expressed or implied by those statements.

The forward-looking statements contained in this announcement relate to Senior, BidCo or any member of the Wider BidCo Group's future prospects, developments and business strategies, the expected timing and scope of the Acquisition and other statements other than historical facts. In some cases, these forward-looking statements can be identified by the use of forward-looking terminology, including the terms "believes", "estimates", "will look to", "would look to", "plans", "prepares", "anticipates", "expects", "is expected to", "is subject to", "budget", "scheduled", "forecasts", "synergy", "strategy", "goal", "cost-saving", "projects" "intends", "may", "will", "shall" or "should" or their negatives or other variations or comparable terminology. Forward-looking statements may include statements relating to the following: (i) future capital expenditures, expenses, revenues, earnings, synergies, economic performance, indebtedness, financial condition, dividend policy, losses and future prospects; (ii) business and management strategies and the expansion and growth of BidCo's, any member of the Wider BidCo Group's or Senior's operations and potential synergies resulting from the Acquisition; and (iii) the effects of global economic conditions and governmental regulation on BidCo's, any member of the Wider BidCo Group's or Senior's business.

By their nature, forward-looking statements involve risk and uncertainty because they relate to events and depend on circumstances that shall occur in the future. These events and circumstances include changes in the global, political, economic, business, competitive, market and regulatory forces, future exchange and interest rates, changes in tax rates, future business combinations or disposals, and any epidemic, pandemic or disease outbreak. If any one or more of these risks or uncertainties, or any other unknown or unpredictable factors, materialises or if any one or more of the assumptions prove incorrect, actual results may differ materially from those expected, estimated or projected. Such forward-looking statements should therefore be construed in the light of such factors.

Neither Senior, the Wider Senior Group, Tinicum, Blackstone, BidCo nor any member of the Wider BidCo Group, nor any of their respective associates or directors, officers or advisers, provides any representation, assurance or guarantee that the occurrence of the events expressed or implied in any forward-looking statements in this announcement shall actually occur. Given these risks and uncertainties, potential investors should not place any reliance on forward-looking statements.

The forward-looking statements speak only at the date of this announcement. All subsequent oral or written forward-looking statements attributable to Senior, the Wider Senior Group, Tinicum, Blackstone, BidCo or any member of the Wider BidCo Group, or any of their respective associates, directors, officers, employees or advisers, are expressly qualified in their entirety by the cautionary statement above.

Senior, the Wider Senior Group, Tinicum, Blackstone, BidCo and each member of the Wider BidCo Group expressly disclaim any obligation to update such statements other than as required by law or by the rules of any competent regulatory authority, whether as a result of new information, future events or otherwise.

No profit forecasts or estimates or quantified financial benefits statements

No statement in this announcement is intended, or is to be construed, as a profit forecast or profit estimate or quantified financial benefits statement for any period and no statement in this announcement should be interpreted to mean that earnings or earnings per share for Senior for the current or future financial years would necessarily match or exceed the historical published earnings or earnings per share for Senior.

Disclosure requirements of the Code

Under Rule 8.3(a) of the Code, any person who is interested in 1 per cent. or more of any class of relevant securities of an offeree company or of any securities exchange offeror (being any offeror other than an offeror in respect of which it has been announced that its offer is, or is likely to be, solely in cash) must make an Opening Position Disclosure following the commencement of the offer period and, if later, following the announcement in which any securities exchange offeror is first identified. An Opening Position Disclosure must contain details of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s). An Opening Position Disclosure by a person to whom Rule 8.3(a) applies must be made by no later than 3.30 p.m. (London time) on the 10th business day following the commencement of the offer period and, if appropriate, by no later than 3.30 p.m. (London time) on the 10th business day following the announcement in which any securities exchange offeror is first identified. Relevant persons who deal in the relevant securities of the offeree company or of a securities exchange offeror prior to the deadline for making an Opening Position Disclosure must instead make a Dealing Disclosure.

Under Rule 8.3(b) of the Code, any person who is, or becomes, interested in 1 per cent. or more of any class of relevant securities of the offeree company or of any securities exchange offeror must make a Dealing Disclosure if the person deals in any relevant securities of the offeree company or of any securities exchange offeror. A Dealing Disclosure must contain details of the dealing concerned and of the person's interests and short positions in, and rights to subscribe for, any relevant securities of each of (i) the offeree company and (ii) any securities exchange offeror(s), save to the extent that these details have previously been disclosed under Rule 8. A Dealing Disclosure by a person to whom Rule 8.3(b) applies must be made by no later than 3.30 p.m. (London time) on the business day following the date of the relevant dealing.

If two or more persons act together pursuant to an agreement or understanding, whether formal or informal, to acquire or control an interest in relevant securities of an offeree company or a securities exchange offeror, they shall be deemed to be a single person for the purpose of Rule 8.3.

Opening Position Disclosures must also be made by the offeree company and by any offeror and Dealing Disclosures must also be made by the offeree company, by any offeror and by any persons acting in concert with any of them (see Rules 8.1, 8.2 and 8.4).

Details of the offeree and offeror companies in respect of whose relevant securities Opening Position Disclosures and Dealing Disclosures must be made can be found in the Disclosure Table on the Panel's website at http://www.thetakeoverpanel.org.uk, including details of the number of relevant securities in issue, when the offer period commenced and when any offeror was first identified. You should contact the Panel's Market Surveillance Unit on +44 (0)20 7638 0129 if you are in any doubt as to whether you are required to make an Opening Position Disclosure or a Dealing Disclosure.

Part B: Certain further terms of the Acquisition

1        Subject to the requirements of the Panel, BidCo reserves the right, in its sole discretion, to waive, in whole or in part, all or any of the Conditions set out in Part A of Appendix I above, except Conditions 2.1(i), 2.2(i), and 2.3(i), which cannot be waived. The deadlines in any of Conditions 2.1(ii), 2.2(ii), and 2.3(ii) may be extended to such later date as (i) may be agreed by BidCo and Senior or (ii) in a competitive situation, as may be specified by BidCo with the consent of the Panel (and, in each case, with the approval of the Court, if such approval is required). If any of Conditions 2.1(ii), 2.2(ii), and 2.3(ii) is not satisfied by the relevant deadline specified in the relevant Condition, BidCo shall make an announcement by 8.00 a.m. on the Business Day following such deadline confirming whether it has invoked the relevant Condition, waived the relevant Condition, or agreed with Senior to extend the relevant deadline.

2       If BidCo is required by the Panel to make an offer for Senior Shares under the provisions of Rule 9 of the Code, BidCo may make such alterations to any of the above Conditions and terms of the Acquisition as are necessary to comply with the provisions of that Rule.

3        BidCo shall be under no obligation to waive (if capable of waiver), to determine to be or remain satisfied or to treat as fulfilled any of the Conditions in Part A of Appendix I above that are capable of waiver by a date earlier than the latest date for the fulfilment of that Condition notwithstanding that the other Conditions of the Acquisition may at such earlier date have been waived or fulfilled and that there are at such earlier date no circumstances indicating that any of such Conditions may not be capable of fulfilment.

4        Under Rule 13.5(a) of the Code and subject to paragraph 5 below, BidCo may only invoke a Condition so as to cause the Acquisition not to proceed, to lapse, or to be withdrawn with the consent of the Panel. The Panel shall normally only give its consent if the circumstances which give rise to the right to invoke the Condition are of material significance to BidCo in the context of the Acquisition. This shall be judged by reference to the facts of each case at the time that the relevant circumstances arise.

5       Conditions 1, 2.1, 2.2 and 2.3 in Part A of Appendix I above, and, if applicable, any acceptance condition if the Acquisition is implemented by means of a Takeover Offer, are not subject to Rule 13.5(a) of the Code.

6        Any Condition that is subject to Rule 13.5(a) of the Code may be waived by BidCo.

7        The Scheme will not become effective unless the Conditions have been fulfilled or (to the extent capable of waiver) waived or, where appropriate, have been determined by BidCo to be or remain satisfied by no later than the Long-stop Date.

8       The Senior Shares acquired under the Acquisition shall be acquired fully paid and free from all liens, equities, charges, encumbrances, options, rights of pre-emption and any other third party rights and interests of any nature and together with all rights attaching or accruing to them, including, without limitation, voting rights and the right to receive and retain in full all dividends and other distributions (if any) declared, made or paid, or any other return of value (whether by reduction of share capital or share premium account or otherwise) by reference to a record date after the Effective Date.

9       If, on or after the date of this announcement and prior to or on the Effective Date, and other than the FY25 Final Dividend, any dividend, distribution or other return of value is declared, made or paid, or becomes payable by Senior in respect of Senior Shares, BidCo reserves the right to reduce the consideration payable under the Acquisition to reflect the aggregate amount of such dividend, distribution or other return of value. In such circumstances, Senior Shareholders shall be entitled to retain any such dividend, distribution or other return of value declared, made, or paid.

If on or after the date of this announcement, and to the extent that any such dividend, distribution or other return of value has been declared, paid, or made, or becomes payable by Senior on or prior to the Effective Date and BidCo exercises its rights under this paragraph 9 to reduce the consideration payable under the terms of the Acquisition, any reference in this announcement to the consideration payable under the terms of the Acquisition shall be deemed to be a reference to the consideration as so reduced.

If and to the extent that such a dividend, distribution or other return of value has been declared or announced, but not made or paid, or is not payable by reference to a record date on or prior to the Effective Date and is or shall be (i) transferred pursuant to the Acquisition on a basis which entitles BidCo to receive the dividend, distribution or other return of value and to retain it; or (ii) cancelled, the consideration payable under the terms of the Acquisition shall not be subject to change in accordance with this paragraph 9.

BidCo also reserves the right to reduce the consideration payable under the Acquisition in such circumstances as are, and by such amount as is, permitted by the Panel.

Any exercise by BidCo of its rights referred to in this paragraph 9 shall be the subject of an announcement and, for the avoidance of doubt, shall not be regarded as constituting any revision or variation of the Acquisition.

10      BidCo reserves the right to elect (with the consent of the Panel, and subject to the terms of the Co-operation Agreement) to implement the Acquisition by way of a Takeover Offer for Senior Shares (other than the Existing Tinicum Shares or any Senior Shares already held by BidCo) as an alternative to the Scheme. In such event, the Takeover Offer shall be implemented on the same terms, so far as applicable, and subject to the terms of the Co-operation Agreement, as those which would apply to the Scheme, subject to appropriate amendments to reflect the change in method of effecting the Acquisition, including (without limitation) if required by the Co-operation Agreement, an acceptance condition set at seventy-five (75) per cent. of Senior Shares or such lesser percentage (being more than fifty (50) per cent.) of Senior Shares as BidCo may decide (subject to the consent of the Panel, to the extent necessary).

11      The availability of the Acquisition to persons not resident in the United Kingdom may be affected by the laws of the relevant jurisdictions. Persons who are not resident in the United Kingdom should inform themselves about and observe any applicable requirements.

12      The Acquisition is not being made, directly or indirectly, in, into or from, or by use of the mails of, or by any means of instrumentality (including, but not limited to, facsimile, e-mail or other electronic transmission, telex or telephone) of interstate or foreign commerce of, or of any facility of a national, state or other securities exchange of, any jurisdiction where to do so would violate the laws of that jurisdiction.

13      The Acquisition is governed by the laws of England and Wales and is subject to the jurisdiction of the courts of England and Wales and to the Conditions and further terms set out in this Appendix I and to be set out in the Scheme Document. The Acquisition shall be subject to the applicable requirements of the Code, the Panel, the London Stock Exchange and the Financial Conduct Authority.

14     Each of the Conditions shall be regarded as a separate Condition and shall not be limited by reference to any other Condition.

(ii)      409,500,376 Scheme Shares (calculated as 419,418,082 Senior Shares in issue referred to in paragraph (i) less 9,917,706 Existing Tinicum Shares) in issue as at 2 April 2026 (being the latest practicable date prior to publication of this announcement).

(iii)     Any references to the issued and to be issued share capital of Senior are based on:

·      419,418,082 Senior Shares in issue referred to in paragraph (i); plus

·    16,768,382 Senior Shares which may be issued on or after the date of this announcement to satisfy the exercise of options or vesting of awards pursuant to the Senior Share Plans (excluding any additional Senior Shares that may be issued by way of dividend equivalents); less

(iv)    The value of approximately £1,275 million on a fully diluted basis, attributed to the entire issued and to be issued share capital of Senior is calculated based on the Cash Consideration payable by Bidco to Scheme Shareholders of 297.85 pence per Scheme Share, multiplied by the issued and to be issued share capital of Senior as set out in paragraph (iii) above.

(v)      The enterprise value of Senior implied by the terms of the Acquisition of approximately £1,399 million is calculated as:

·      the value of Senior's entire issued and to be issued share capital as set out in paragraph (iv) above; plus

(vi)     The implied multiple of 15.2 times Senior's adjusted EBITDA for the year ended 31 December 2025 is calculated as:

·      the enterprise value set out under paragraph (v) above; divided by

·    Senior's adjusted EBITDA for the year ended 31 December 2025 of £92.3 million (which is calculated as Senior's adjusted operating profit for the year ended 31 December 2025 of £63.6 million, plus Senior's depreciation and amortisation including the depreciation of right-of-use assets of £30.3 million for the year ended 31 December 2025, less amortisation of intangible assets from acquisitions of £1.6 million for the year ended 31 December 2025).

(vii)    The implied multiple of 22.0 times Senior's adjusted operating profit for the year ended 31 December 2025 is calculated as:

·      the enterprise value set out under paragraph (v) above; divided by

·      Senior's adjusted operating profit for the year ended 31 December 2025 of £63.6 million.

(viii)    The closing price for Senior Shares are the relevant closing middle market price sourced from Bloomberg.

(ix)     The volume-weighted average prices of Senior Shares have been sourced from FactSet.
