INTERNATIONAL PUBLIC PARTNERSHIPS LIMITED

('INPP', 'the Company')

FULL YEAR RESULTS FOR THE YEAR ENDED 31 DECEMBER 2023

Robust, inflation-linked cash flows underpin progressive dividend policy

International Public Partnerships, the FTSE 250-listed infrastructure investment company ('INPP' or the 'Company', is pleased to announce its results for the year ended 31 December 2023.

Mike Gerrard, Chair of International Public Partnerships, said: "The Board continues to believe in the robustness and resilience of INPP's low-risk portfolio and the long-term investment case for generating predictable, inflation-linked returns from investing responsibly in social and public infrastructure. Even if the Company does not make any new investments, the projected cash flows are sufficient to fulfil INPP's progressive dividend policy for the next 20 years[i]."

"We have proactively sought to improve shareholder returns by optimising the portfolio through c.£200 million in asset realisations, repaying all cash drawings under the Corporate Debt Facility ('CDF') and allocating up to £30 million to a share buyback programme. We have also announced a further increase in INPP's full-year 2024 dividend target following another year of strong operational and financial portfolio performance."

SHAREHOLDER RETURNS

·    The Company continued to deliver robust and predictable shareholder returns with full-year dividend growth of 5% to 8.13 pence per share (31 December 2022: 2.5% growth to 7.74 pence per share) in line with the increased dividend target announced at the Company's Interim Results for 2023.

·    Inflation remained elevated during the year and although it has now moderated, the Board  is pleased to announce a further increase to the annual dividend growth target of 3% for 2024 to 8.37 pence per share[ii].

·    The Board reiterates its long-term projected annual dividend growth rate of 2.5% thereafter such that the 2025 dividend target is currently forecast to be 8.58 pence per shareⁱⁱ.

·    The Company has maintained its track record of growing the dividend every year since its 2006 IPO, with 2023 dividend cover of 1.1x[iii] (31 December 2022: 1.3x)

·    Strong inflation-linkage of 0.7% has also been maintained, generating long-term real rates of shareholder returns notwithstanding volatile macroeconomic conditions; and

·     The Board previously announced a reassessment of the Company's long-term total return target of 7% given the changes in the macroeconomic environment. Following the reassessment, the Board has confirmed the static target will be replaced by qualitative factors to inform its assessment of new investments, including: (i) the Company's share price relative to its NAV, (ii) the Company's weighted average discount rate, and (iii) any pertinent economic or strategic considerations prevailing at the time of investment.

VALUATION

·    The Company's Net Asset Value[iv] ('NAV') decreased by 4.1% to £2.9 billion, or 152.6 pence per share (31 December 2022: 159.1 pence).

·    The NAV reduction reflects, among other factors, the dividends paid during the year as well as a modest increase in the discount rates used to value the forecast cash flows.

·    IFRS profit before tax was £28.0 million (31 December 2022: £326.8 million), principally reflective of the unrealised fair value loss on the portfolio in the year.

·    The Company's shares maintained low correlation to the FTSE All-Share Index, of 0.4 over the 12 months to 31 December 2023 (31 December 2022: 0.33).

CAPITAL ALLOCATION AND DISCOUNT MANAGEMENT

The Board and its Investment Adviser continue to believe the discount to the NAV at which the Company's shares are trading materially undervalues the Company. At the time of Company's 2023 Interim Results, the Board committed to taking a number of actions to optimise the portfolio and reallocate capital to improve shareholder returns. The Company has made good progress against these commitments as can be seen from the updates set out below. Notwithstanding that, consistent with the wider investment trust sector, the share price continues to trade at a discount to the NAV and therefore the Board and the Investment Adviser continue to maintain a focus on actively managing the portfolio to ensure the Company remains well positioned for the long-term. In addition to increasing the dividend targets for 2023 and 2024, the following measures have been undertaken:

Approximately £212m in cash proceeds raised from asset realisations

·   In December 2023, the Company generated cash proceeds of c.£200 million from the realisation of four Offshore Transmission ('OFTO') senior debt investments as well as the addition of prudent leverage to the Lincs OFTO. The four senior debt investments were realised at a modest premium to the Company's half-year valuation.

·    In July 2023, the Company generated cash proceeds of c.£12 million following the divestment of its stake in Airband, a leading alternative network provider in the UK. The divestment was through the Amber-advised National Digital Infrastructure Fund ('NDIF') and the sales proceeds were in line with INPP's 30 June 2023 valuation.

Fully repaid the Corporate Debt Facility

·    During the year, using surplus free cash flow as well as proceeds from the Airband divestment and OFTO realisations, cash drawings under the CDF were reduced to £65 million and post year-end, all cash drawings were fully repaid such that the £350 million CDF currently has no cash drawings but with £14 million in letters of credit supporting long-standing investment commitments.

Launched £30m share buyback programme

·    Following the full repayment of the CDF, up to £30 million in cash proceeds from the OFTO realisation were allocated to fund a 12-month share buyback programme. As at 27 March 2024, c.£5 million shares have been bought back.

·     The sustainability and predictability of projected cash receipts from the Company's portfolio mean that even if no further investments are made, the Company's projected cash receipts are sufficient to continue meeting its existing progressive dividend policy (of c.2.5% annual growth) for at least the next 20 yearsⁱ.

INVESTMENT ACTIVITY

The Company made £108.1 million of new cash investments during the year, which included completing acquisitions which the Company had committed to invest in prior to the current volatile macroeconomic environment. The Company also marked its first acquisition in New Zealand during the year.

·    PPP portfolio, New Zealand: In June 2023, the Company acquired a portfolio of five infrastructure assets in New Zealand, including three groups of schools, a correctional facility, and a purpose-built student accommodation facility at the Auckland University of Technology. The investments are operational and delivering long-term stable cash flows linked to inflation.

·     Ealing Building Schools for the Future ('BSF'), UK: In March 2023, the Company acquired a further 20% investment in Ealing BSF, increasing its holding to 100%. This BSF scheme provides education facilities to over 1,400 pupils.

In addition, in December 2023 the Company committed to acquire its eleventh OFTO investment, Moray East OFTO. This acquisition, totalling c.£77 million, was completed in February 2024 (post-year end) using the proceeds from the previous OTFO realisations and will further increase the Company's contribution to the UK's transition to a net zero carbon economy. The investment has the capacity to transmit sufficient renewable electricity to power the equivalent of c.1.0 million homes, increasing the total equivalent across the Company's OFTO portfolio to c.3.7 million homes.

The Company continues to assess further investment opportunities, particularly where they are favourable to alternative capital allocation options and align to relevant strategic KPIs.

PORTFOLIO PERFORMANCE AND ASSET STEWARDSHIP

Energy transmission | SDG 7: Affordable and clean energy

The Company's OFTO investments are regulated by Ofgem, which has granted those OFTOs licences to transmit electricity generated by offshore wind farms into the onshore grid. INPP currently has a portfolio of 11 OFTO investments.

Ofgem continues its consultation process regarding the potential regulatory developments underpinning an extension to the OFTO revenue stream. In January 2024, Ofgem published decisions which confirmed the regulator's overarching objective to maximise the combined operational lifetimes of both generation and transmission assets where it is economic and efficient to do so. Ofgem expects incumbent OFTOs to be best positioned to operate transmission assets in an extension period with their preferred approach being to promote bilateral negotiation with the incumbent OFTO when setting any extension revenue stream.

The Investment Adviser is actively engaged with all relevant industry stakeholders. All parties recognise that the life extension of renewable energy assets is required to meet the UK net zero emissions targets.

Gas distribution | SDG 9: Industry innovation and infrastructure

Cadent continues to support the UK Government in meeting its net zero target, working closely with the Department for Energy Security and Net Zero ('DESNZ') in supporting its Heat and Buildings Strategy, and Hydrogen Strategy, to consider hydrogen as a component of the UK's future energy mix. Cadent also continues to actively engage with the UK Government and regulators to build awareness of the opportunities offered by green cases in the UK's net zero transition.

While Cadent is largely insulated from changes in gas prices and the associated energy price caps, aside from where the changes can cause timing differences in certain cash flows, the Company continues to closely monitor the implications of changes in gas prices and other developments in the sector.

Wastewater | SDGs 6, 8, 9 & 11: Clean water and sanitation; decent work and economic growth; industry innovation and infrastructure; sustainable cities and communities

Tideway remains one of the top investments in the Company's portfolio by fair value. Construction has continued to progress, with overall works over 90% complete at 31 December 2023 and the project remaining on course to be fully operational in 2025.

The project continues to progress well. Notable milestones being reached during the year, include the completion of the secondary lining and the opening of the first new area of public realm. The estimated cost of the project remains in line with the £4.5 billion stated in INPP's Half-yearly Financial Report for the six months to 30 June 2023 and the cost to customers remains well within the initial estimate provided at the outset of the project.

Tideway continues to monitor developments in relation to the financial position of Thames Water which is being reported on by the media. The matter is not expected to have a material impact on the Company's investment in Tideway. Whilst Thames Water possesses a licence requirement to collect Tideway's revenues from its customers, and pass those amounts onto Tideway, statutory and regulatory protections are afforded to Tideway which are designed to mitigate the risk of disruption to the receipt of revenues in the event that Thames Water's financial standing changes.

Digital infrastructure | SDG 9: Industry, innovation and infrastructure

During the year, the Company completed the sale of its stake in Airband through the Amber-managed NDIF. INPP first invested in Airband in 2018 and supported the business in expanding its fibre network to cover more than 290,000 homes in the West of England. INPP has two remaining investments in digital assets - toob and Community Fibre.

In May 2023, the Company expressed its intention to invest a further c.£13 million into toob, alongside additional capital from NDIF. The Company's investment is expected to be made during 2024 and 2025. toob has a current fibre network covering 190,000 premises in the South of England. INPP's further investment is part of a wider potential £300 million of additional funding raised by the business, to expand its reach across 600,000 premises.

OUTLOOK

The Board and Investment Adviser remain confident in the proactive measures initiated to date to optimise the portfolio and reallocate capital to address the discount at which the Company's shares are trading.

The Board and Investment Adviser will continue to monitor the extent to which these initiatives are having the anticipated impact on the Company's valuation and remain open to further mechanisms that can support in narrowing the discount and generating further returns for shareholders.

The Company's prospects are highly attractive. INPP's investment case is underpinned by the long-term nature of the portfolio and the inflation-linkage of the Company's projected cash receipts. As such, the Board and Investment Adviser are confident the Company will continue to meet its investment objectives, supported by diligent asset management and a prudent approach to portfolio management, as well as a sustained focus on robust shareholder returns as evidenced during the year.
