Corporate Reorganisation

3

▪ The trading performance of One51 has improved significantly in recent years

as it has emerged from a period of restructuring as a transformed Group

focused on the development and growth of its core plastics operations.

▪ The IPL business continues to grow as One51 seeks to expand IPL’s

geographic footprint and product offering and is growing at a faster rate than

OPG’s European business.

▪ One51 is now focused on the next phase of its strategy which includes

seeking a liquidity event for shareholders.

▪ A reorganisation of One51’s corporate structure is required in advance of, or

in conjunction with an IPO.

▪ It is proposed that CDP Investissements Inc. (‘CDPQ’) and Fonds de

Solidarité des Travailleurs du Québec (‘FSTQ’) exchange, in a corporate

reorganisation, their respective equity investments in IPL for equity in One51.

The Reorganisation would be implemented, with the agreement of CDPQ and

FSTQ, in conjunction with an IPO and Listing or at such other time (not being

later than 31 December 2018) as the parties might agree.

INTRODUCTION

▪ There are a number of significant benefits to One51 and its shareholders

arising out of this proposed corporate reorganisation, for example a global

refinancing, the removal of duplicate Head Office costs, the cross-selling of

products, etc.

▪ The corporate reorganisation and the IPO preparatory steps require the

approval of a number of Shareholder Resolutions (as set out on Slides 11-14)

at today’s Extraordinary General Meeting (EGM).

INTRODUCTION

Group Structure Following IPL Acquisition

▪ In July 2015, One51 acquired a majorityshareholding in IPL together withCDPQ, a long- term institutional investorthat manages funds primarily for theCanadian public sector, and FSTQ, aCanadian government agency whichsupports investment in Quebec.

▪ Due to the structure in IPL:

➢ IPL is not fully integrated into the One51Group.

➢ Acquisition and working capital financingrequires cashflows to be ring-fenced withinthe IPL structure.

➢ Governance and shareholder arrangementsare in place between IPL shareholders.

➢ Encore, Macro and any future NorthAmerican acquisitions are executed withinthe IPL structure.

➢ The current structure is inefficient in terms ofcapital utilisation.

Current Group Structure

▪ One51’s investment in IPL is governed by a shareholders’ agreement which includes a Put/CallOption.

▪ The Put Option is exercisable by CDPQ and FSTQ from 23 July 2021.

▪ The Call Option is exercisable by One51 prior to that date only in the event of a One51 liquidityevent (i.e. IPO or change of control of One51 plc), at a Fair Market Value to be determined.

▪ Due to the continuing improving financial performance of IPL, it is expected that the value of the putliability will continue to grow at a faster rate than the value of One51 Equity.

Swap-up of IPL

Shareholding to

One51 Equity

▪ The number of One51 shares to be allocated to CDPQ and FSTQ as part of the corporatereorganisation is calculated in accordance with a framework set out in the Heads of Agreement(methodology originally agreed in July 2015).

▪ The framework sets out the methodology to determine the One51 equity to be issued in exchangefor the IPL minority interests.

▪ The methodology is as follows:

1. A Trailing Twelve Month (TTM) EBITDA to 30 June 2017 has been calculated for both the IPLand Non-IPL Plastics Business.1

2. A multiple of 8 times has been applied to the EBITDA of each of IPL and the Non-IPLBusiness to determine the ‘deemed’ enterprise value of the respective businesses.

3. The ‘deemed’ enterprise value has been adjusted for the value of any excess net assets² thatdo not contribute to EBITDA, in-the-money options and net debt allocation in order to arrive atthe ‘deemed’ equity value.

4. The aggregate number of new One51 shares to be issued to CDPQ and FSTQ has beendetermined based on the parties’ relative ownership percentages of the ‘deemed’ equity value.

▪ Based on this methodology, 47,238,242 new shares in One51 will be issued to CDPQ (31,492,161)and FSTQ (15,746,081), representing c.14.65% and c.7.32% respectively of the enlarged fullydiluted share capital of One51.

▪ Even though the reorganisation may not occur until the happening of an IPO, the economics of thetransaction are fixed.

Share Exchange Framework

91. Note: TTM EBITDAs have been adjusted such that they include a whole 12 month period for acquisitions made by the One51 Group during the 12

month period to 30 June 2017.

2. Note: In the case of One51 this includes any residual assets & liabilities held on the balance sheet that are not captured in the EBITDA of OPG.

Trading Update

15

▪ The Company expects its full-year EBITDA for 2017 to be broadly in line with market expectations notwithstanding a number of headwinds facing the business.

▪ IPL (including Macro) has performed strongly, driven by continued organic growth and demand for its products in the US and Canadian markets. Results were negatively affected in H2 2017 by the decline in the value of the Canadian and US Dollars and by significantly increased resin and transport costs following the recent hurricanes in the US.

▪ UK business continues to perform solidly, notwithstanding ongoing political and economic uncertainties in the UK.

▪ Irish business has been adversely impacted by reduced demand from the Group’s largest customer and delays in embedding new customers into the new food grade facility in Cork which was commissioned for full production in 2017.

▪ The post acquisition integration of Macro is progressing well. One51 announced the acquisition of Macro Plastics Inc in June 2017 and trading has been in line with expectations.

▪ The major capital investment programme announced in 2016 is ongoing with a number of development projects starting to contribute to Group EBITDA in H2 2017. These investments will enable IPL to accelerate its geographic expansion and customer reach across Canada and the United States to meet significant and growing market demand for its products.

Conclusion

17

▪ The Board has considered the strategic rationale for the corporate reorganisation:

➢ More efficient group structure allowing for the full integration of IPL, Encore andMacro and any future North American acquisitions into the One51 Group;

➢ Improved governance, management, legal, financial and operational structuresrequired to implement One51’s growth strategy;

➢ Further revenue and cost benefits across sales, R&D and operational activities;

➢ Benefits from refinancing of IPL acquisition debt into a group facility;

➢ Value enhancing to One51 shareholders; and

➢ Facilitates an IPO or other corporate transaction

▪ Alternatively, if these proposals are not implemented, then none of those benefits will then to accrue to One51 and there can be no assurance that they will accrue, which the Board and management believe would be detrimental to shareholder value.

▪ The Board considers the corporate reorganisation to be in the best interests of One51 and its shareholders as a whole. The Board has received a fairness opinion on the terms of the corporate reorganisation (and share exchange) from IBI Corporate Finance.

Conclusion (1)

18

▪ Shareholders are being asked to vote on a number of Resolutions to allow

implementation of the corporate reorganisation and to facilitate an IPO.

▪ The Board considers that the corporate reorganisation, by positioning the

Company for an IPO, best enables the Company to secure and allow

realisation of value by shareholders. The Board will actively continue to

consider any alternative proposals (that might be put forward) for the

recognition and realisation of shareholder value. The Board, on occasion,

receives expressions of interest from third parties indicating a desire to

acquire ownership and/or control of One51. These proposals are often

speculative and highly conditional. The Board evaluates all such proposals

and would put any such proposal to the shareholders for acceptance or

rejection as the case may be once the Board believes that the proposal is

supportable, capable of implementation (including regarding conditionality)

and at an appropriate valuation.

Conclusion (2) - Continued

19

▪ The Board recommends that shareholders vote in favour of the Resolutions as

the Directors intend to do in respect of their own shareholdings.

▪ The Board continues to explore a possible IPO and Listing for One51 by the

end of 2018, including consideration of Listing venue and the optimal listing

structure.

▪ The Board are also considering all other options with the objective of

maximising shareholder value and delivering a liquidity event for our

shareholders.

▪ Further announcements will be made as appropriate.
