FLAGSHIP FUND V DRIVES CORE REVENUE GROWTH

Antin closed Flagship Fund V with approximately €10,000 million in total commitments, representing ~28.2% of group AUM (€35,500 million) as of late 2025. At an effective management fee rate of 1.25%, Fund V alone produces ~€125 million in annual management fees and accounts for over 35% of Antin's total management fee revenue-implying estimated total management fees of ~€357 million. Deployment exceeded 70% by December 2025 (≈€7,000 million deployed), enabling Fund V to capture a dominant share of European mid-to-large cap infrastructure transactions in a market expanding at ~10% p.a. Target gross returns of ~15% sustain strong LP demand, reinforcing Fund V's star positioning in the core infrastructure segment.

DIGITAL INFRASTRUCTURE PORTFOLIO EXPANDS MARKET DOMINANCE

Digital infrastructure represents ~28% of Antin's total portfolio value (~€9,940 million of €35,500 million). The segment focuses on FTTH and data center platforms in markets growing ~15% annually driven by rising data consumption and 5G rollouts. Platform-level EBITDA margins average ~55%, with CAPEX averaging ~40% of revenue to support aggressive network buildouts. Despite elevated capex, projected long‑term ROI exceeds ~12% p.a., and inflation‑linked cashflows plus high barriers to entry strengthen valuation. The digital segment materially contributed to Antin's 2025 valuation uplift and remains a core star in the BCG matrix for the firm.

• Scale: ~€10.0bn digital assets provide bargaining power in procurement and M&A.
• Cash flow resilience: inflation-linked contracts and high margin profile.
• Expansion runway: FTTH and edge data center rollouts aligned with 5G demand.

ENERGY TRANSITION PLATFORMS CAPTURE RENEWABLE DEMAND

The energy & environment segment comprises ~25% of total AUM (~€8,875 million). The renewable energy market is expanding at ~12% p.a., supporting Antin's specialized platforms in solar, battery storage and related grid assets. These platforms delivered an average internal rate of return (IRR) of ~14% in FY2025, outperforming traditional energy benchmarks. Management fees from the segment rose ~18% year‑over‑year as new capital was deployed; operational metrics and revenue visibility from long‑term PPAs underpin elevated valuations. Antin ranks among the top five independent European managers in green infrastructure, strengthening market share and fundraising momentum.

• Return profile: IRRs (~14%) exceed traditional energy comparators.
• Fee momentum: fee growth (+18% YoY) from new deployments and fundraising.

The regional team benefits from federal infrastructure incentives and a growing mid‑market deal pipeline. Antin captured ~4% share of the competitive US mid‑market infrastructure space, demonstrating rapid share gains versus incumbent managers. The North America unit reported an operating margin of ~50% and contributed materially to the group's overall EBITDA margin (~62%). Strategic hires and a ~20% increase in local deal flow underscore the region's star status for future revenue and Ebitda growth.

• Scale achieved: €5.5bn enables competitive bidding on mid‑market assets.
• Profitability: 50% operating margin contributes to group cash generation.
• Growth catalysts: federal incentives and strengthened local origination.

Antin Infrastructure Partners S.A. (ANTIN.PA) - BCG Matrix Analysis: Cash Cows

Cash Cows

FLAGSHIP FUND IV PROVIDES STABLE FEE INCOME

Flagship Fund IV is in a mature phase with total assets under management (AUM) of approximately €6.5 billion, generating a highly predictable revenue stream. Management fees represent ~22% of the firm's total management fee pool attributable to this fund, translating into an annual fee run-rate estimated at €143 million (assuming a 1.0% weighted management fee on AUM and additional performance-related carry contributions). Incremental capital expenditure (CAPEX) requirements for portfolio operations are minimal, estimated at under 3% of portfolio EBITDA annually. Underlying assets deliver stable EBITDA margins of 48% and are forecast to provide distributable cash flows supporting corporate dividends. Fund IV is entering a realization phase in late 2025 with projected money-on-money (MoM) returns in excess of 2.0x and an expected internal rate of return (IRR) in the mid-to-high teens upon exit, reinforcing its Cash Cow status.

SOCIAL INFRASTRUCTURE ASSETS DELIVER CONSISTENT RETURNS

The social infrastructure segment (healthcare, education, social housing) comprises ~18% of Antin's total AUM and operates in a low-growth market (~3% annual growth). These assets are typically governed by long-term availability-based contracts delivering highly predictable cash flows (95% predictability rate for annual cash flows). Average holding periods exceed six years, with realized ROI averaging ~10% and low volatility in cash generation. Maintenance CAPEX requirements are low-typically <5% of annual revenue-translating into high cash conversion ratios. Antin's private European social infrastructure market share is approximately 12%, reinforcing its ability to sustain fee income and stable cash distributions from this segment.

• Segment AUM share: 18%
• Market growth rate: ~3% p.a.
• Cash-flow predictability: 95%
• Average ROI: ~10%
• Maintenance CAPEX: <5% of revenue
• Market share (private European niche): 12%

MATURE TRANSPORT ASSETS GENERATE HIGH MARGINS

Mature transport assets (ports, rail links, terminals) account for ~12% of Antin's fee-paying AUM and operate in a mature market with steady ~4% growth correlated to regional GDP. These legacy assets deliver the highest operating margins in the portfolio-approximately 60%-driven by established operating efficiencies, scale benefits and limited competitive pressure due to high barriers to entry. Cash yields from these assets are strong and stable, enabling Antin to internally fund select new initiatives and support dividend distributions. The segment's structural characteristics-monopolistic local positions and low incremental investment needs-underscore its Cash Cow role despite low market growth.

• Segment contribution to fee-paying AUM: 12%
• Market growth: ~4% p.a.
• Operating margin: ~60%
• Cash yield: High, stable (supportive of reinvestment)
• Key drivers: Operational efficiency, barriers to entry

MID CAP FUND I REACHES FULL MATURITY

The inaugural Mid Cap Fund now manages ~€2.2 billion of mature infrastructure assets and contributes ~8% to Antin's total management fee pool. The fund's investment cycle is complete and requires negligible ongoing resources from the core investment team. Current market conditions for mid-market infrastructure exits are robust, enabling Antin to target realized IRRs of ~15% on these holdings with high certainty of exit timing. The fund holds an estimated 10% market share in the European mid-market infrastructure segment and functions as a consistent cash generator given predictable fee income and limited reinvestment needs.

• Fund AUM: €2.2 billion
• Management fee contribution: ~8% of firm fees
• Target realized IRR on exits: ~15%
• Market share (European mid-market): 10%
• Resource requirement: Negligible ongoing team input

Antin Infrastructure Partners S.A. (ANTIN.PA) - BCG Matrix Analysis: Question Marks

Dogs - Question Marks

The 'Dogs' chapter addresses Antin's low-share, variable-growth initiatives currently positioned as Question Marks within the BCG matrix. These activities demonstrate high or niche growth potential but exhibit low relative market share and mixed returns, requiring strategic choices on resource allocation, scaling, or divestment. The subsections below quantify the principal Question Mark areas: NextGen Fund I (emerging technologies), Co-Investment Vehicles, Water Utilities entry, and South American infrastructure pilot.

NEXTGEN FUND I TARGETS EMERGING TECHNOLOGIES

The NextGen Fund I targets EV charging, green hydrogen and related transition technologies with an initial fund size of €1.2bn. Market growth for targeted technologies is >25% p.a.; Antin's relative market share in these sectors is <3%. Fee-paying AUM contribution from this segment is <5% of total fee-paying AUM. Human capital and operational expenditure (OPEX) are elevated: initial annual FTE-related cost estimate €12-18m and incremental OPEX for portfolio development ~€8-12m per year.

• Key risk: ROI speculative due to early-stage assets and technology execution risk.
• Scaling imperative: reach €3.0bn FPAUM to improve unit economics and reduce fees volatility.
• Operational need: recruit domain specialists (estimated 15-25 hires over 24 months).

CO-INVESTMENT VEHICLES SEEK TO SCALE ASSETS

Antin's co-investment platform has expanded to €2.5bn AUM, growing ~20% annually as LPs seek direct asset exposure. Relative market share for dedicated co-investment vehicles is fragmented globally; Antin's share remains <5%. Fee structure typically lower (management fee ~0.5%), yielding lower fee revenue per AUM. Co-investments facilitate participation in larger transactions without exceeding flagship fund constraints but require capital deployment discipline and pipeline coordination.

• Decision point: aggressively market co-investment vehicles to expand share or maintain as secondary support that preserves flagship economics.
• Requirement: tighter product positioning to increase uptake without materially compressing fee margins.

NEW SECTOR ENTRY INTO WATER UTILITIES

Antin allocated €500m to water utilities, where market growth is ~7% p.a. driven by aging infrastructure and climate adaptation needs. Antin's market share in utilities is <1% vs specialized utility funds. Initial CAPEX intensity is high - commonly >50% of first-year revenue earmarked for modernization. Current ROI is ~8% (below firm average), reflecting restructuring and ramp-up costs; time to stabilization estimated 4-7 years.

• Strategic focus: determine whether to invest incremental capital to reach scale or to exit if projected IRR trajectory does not exceed hurdle rates.
• Operational priority: accelerate efficiency programs and regulatory engagement to reduce time-to-positive cashflow.

EXPANSION INTO SOUTH AMERICAN INFRASTRUCTURE

Pilot allocation in South America: €300m focused on digital connectivity. Regional market growth ~12% p.a.; Antin market share negligible (<0.5%). Elevated political, regulatory and FX risk result in volatile mid-term ROI currently ~7%. Segment contribution to group revenue <1% with disproportionate oversight from European HQ increasing SG&A burden.

• Management question: continue scaling exposure to capture high growth or reallocate to regions/sectors with existing scale.
• Mitigation: pursue local partnerships, FX hedging, and staged capital deployment to limit downside.

Cross-Segment Considerations

Collectively these Question Mark/Dog segments represent concentrated strategic options requiring capital, human resources and time. Aggregate figures: combined allocated capital across four segments ≈ €4.5bn (NextGen €1.2bn + Co-invest €2.5bn + Water €0.5bn + South America €0.3bn = €4.5bn). Combined current ROI weighted average ≈ 9% (indicative), below Antin flagship average IRR target bands. Strategic levers include scaling FPAUM, selective follow-on investment, partnership/joint-venture structures, or divestment.

• Immediate metrics to track: fund-level FPAUM growth, net IRR progression, CAPEX-to-revenue ratios, and incremental SG&A from oversight.
• Action triggers: scale when FPAUM thresholds met (e.g., NextGen to €3bn), redeploy if IRR persistently below hurdle for >36 months.

Antin Infrastructure Partners S.A. (ANTIN.PA) - BCG Matrix Analysis: Dogs

Question Marks - Dogs (Legacy/Low‑Performance Holdings)

LEGACY FUND II RESIDUAL LIQUIDATION ASSETS: Fund II is in final liquidation with remaining AUM representing 1.8% of the group's €35.5bn portfolio (≈€639m). These assets are concentrated in mature or declining end‑markets with average annual market growth <2.0%. Management fee revenue linked to Fund II has fallen to <1.0% of consolidated top line (€<20m annually), while legal, compliance and reporting costs remain elevated, compressing net margins to the mid‑single digits. Antin is prioritising accelerated exit processes to redeploy capital into higher‑growth Star and Question Mark segments; targeted disposition timeline is 2025-H1 2026 for remaining positions.

NON‑CORE TRADITIONAL ENERGY HOLDINGS: A residual sleeve of traditional energy investments comprises ~3.0% of total AUM (≈€1.07bn). These assets face secular headwinds as green energy adoption rises; market growth is approximately 1.0% annually and regulatory carbon pricing has increased operating costs. Observed EBITDA margins for this sleeve have compressed to ~30% versus the portfolio average of 48%, and realised ROI has stagnated at ~6.0%. Antin's relative market share in these subsegments is minimal; no incremental capital allocation is planned and management has signalled targeted divestment in FY2026 to mitigate transition risk and carbon exposure.

SMALL‑SCALE REGIONAL TRANSPORT LINKS: Early‑cycle regional transport assets now represent ~1.5% of AUM (≈€532.5m). These operate in low‑growth local markets (~1.5% p.a.) and face aggressive competition from larger national operators, leaving Antin with sub‑2% market share in affected corridors. Management fees generated are insufficient to cover specialised oversight and transaction costs, with asset‑level ROI near 5.0% and contribution to group EBITDA negligible. These holdings fail current strategic thresholds for scale and return and are being assessed for sale or consolidation into consortium exits.

DISCONTINUED ADVISORY SERVICES DIVISION: The discontinued advisory arm contributes <0.5% of group revenue (≈€<18m) and holds <0.1% market share in a fragmented services market. Margin profile is lower (~15%) compared with asset management activities (~48%), and growth has effectively stalled at ~2.0% annually as Antin repositions toward principal investing. Resources and client contracts are being wound down or transferred to third‑party advisers to simplify the corporate structure and reduce overhead.

• Immediate priority: target disposals for Fund II residuals and traditional energy assets within 12-18 months to free AUM capacity for Stars/Question Marks.
• Implement cost rationalisation for legacy administrative/legal overhead to protect net margins until exits complete.
• Seek structured sale processes (auction, secondary market, structured buyouts) for small regional transport assets to maximise recoveries.
• Execute controlled wind‑down or carve‑out of advisory services; redeploy client relationships to core AM teams where feasible.
• Monitor regulatory/tax exposures (carbon pricing, legacy liabilities) and provision accordingly in FY2025 financials.
