Altri, SGPS, S.A. (ALTR.LS) - BCG Matrix Analysis: Stars

Stars

Altri's Stars comprise high-growth, high-share business units that are primary drivers of near-term profitability and strategic positioning. Two core Stars are highlighted: the Caima dissolving pulp unit focused on sustainable textile applications and the Biotek mill producing specialty hardwood pulp for premium tissue. Both units operate in markets expanding at double- and mid-single-digit rates, deliver elevated EBITDA margins, and have received focused CAPEX to scale and differentiate product quality.

The Caima dissolving pulp segment targets the cellulosic textile market, which is currently experiencing an estimated global compound annual growth rate (CAGR) of 8.0%. Caima contributes 15.0% of Altri group revenue and achieved an EBITDA margin of 28.0% as of December 2025. Capital investment allocated to Caima totals over €45.0 million to optimize production lines, improve pulp purity and consistency, and meet textile-industry specifications. Caima commands a 12.0% share of the European specialty dissolving pulp niche and realizes an ROI of 18.0% driven by premiums over standard paper-grade pulp and favorable contract terms with fiber-to-fashion customers.

The Biotek specialty hardwood pulp unit serves premium tissue manufacturers with high-porosity, high-strength pulp. The served market grows at approximately 6.0% per year. This product line represents 20.0% of Altri's total sales volume and achieves a pricing premium of 15.0% versus benchmark BHKP prices. EBITDA margin for Biotek reached 26.0% in the 2025 fiscal year. Recent technical upgrades and process optimizations, supported by €20.0 million in targeted CAPEX during 2025, have improved fiber strength and softness metrics, resulting in a segment ROI of 16.0% and a 10.0% share of the European premium tissue pulp supply chain.

Operational and commercial KPIs underpinning these Stars include production yields, product purity, long-term off-take contracts, and export mix. Key 2025 operational figures: Caima average annual production capacity utilization 92.0%, Caima average realized pulp grade purity 98.5% alpha-cellulose equivalent, Biotek fiber tensile index improvement +6.0% post-upgrade, and combined export share of Star outputs 68.0% of volumes.

• Investment priorities: continued CAPEX for capacity optimization (€45.0m Caima, €20.0m Biotek), R&D on fiber functionalization, and process energy-efficiency upgrades to protect margins.
• Market development: secure long-term supply agreements with textile brands and tissue manufacturers to stabilize premium pricing and support capacity ramp.
• Margin protection: focus on feedstock cost management, vertical integration where feasible, and premium product differentiation to sustain 26-28% EBITDA margins.
• Scale and share targets: aim to increase European niche shares by 2-3 percentage points over the next 3 years through capacity tweaking and commercial expansion.

Financial contribution modeling for 2025 indicates: combined Star revenue share approximately 35.0% of group revenue, combined EBITDA contribution estimated at ~27.0% weighted margin, and incremental free cash flow generation supporting reinvestment and deleveraging efforts. Sensitivity analysis shows a 100-basis-point change in realized price premiums would move Star EBITDA by an estimated €8-10 million annually, while a 5% change in capacity utilization would alter segment EBITDA by ~€3-5 million.

Consolidated Cash Cow Metrics (2025)

Altri, SGPS, S.A. (ALTR.LS) - BCG Matrix Analysis: Question Marks

Dogs quadrant assessment - projects currently generating low market share relative to competitors in markets that nonetheless exhibit variable growth dynamics; two Altri initiatives (Project Gama and lignin/bio-chemical extraction) present the characteristics of 'question marks' with potential to move to Stars or remain Dogs depending on execution, funding and market traction.

Project Gama - lyocell fiber production initiative: Project Gama targets the fast-growing lyocell market, with estimated market growth of 12% CAGR. The asset is in final commissioning and scaling, contributing below 1% to Altri's revenue during startup. Commercial market share is effectively 0% at present. Total CAPEX committed: €800 million, financed through a mix of debt and internal cash, materially increasing group net debt in 2025. Target full capacity: 200,000 tonnes/year. Forecast once stabilized: EBITDA margin >30%, projected ROI ~15% at steady state. Current operational status: commissioning, ramp-up; near-term cash flow negative due to construction depreciation, interest expense and low initial sales volumes.

Lignin extraction and bio-chemical derivatives: Altri is piloting lignin recovery and conversion into high-value molecules and intermediates (resins, carbon fiber precursors, specialty chemicals). Addressable global market growth estimated at 10% CAGR. Current contribution to group revenue: <2%; global market share: <0.5%. Committed R&D/CAPEX to date: €12 million (pilot plants, application development). Margin potential for commercial molecules: estimated up to 40% gross margin for niche products. Current ROI: negative while scaling and product qualification continue. Commercialization hinge factors include: process yield improvements, cost of lignin isolation per tonne, regulatory approvals for end-use applications, and strategic industrial partnerships for scale-up.

Risk profile and operational considerations for both initiatives:

• High upfront capital intensity (Project Gama: €800m) increasing leverage and interest burden.
• Commercialization risk: time-to-market, product certification, and buyer adoption delays.
• Scale-up technical risk: process yields, continuity of cellulose feedstock, and energy integration.
• Market-price risk: volatility in textile and specialty chemical prices could compress margins.
• Partnership dependency: lignin/bio-chem success requires industrial off-takers or licensing agreements.

Key financial sensitivities and break-even dynamics:

• Project Gama break-even sensitivity: EBITDA margin retention >25% and sales utilization >60% required to reach payback within 7-10 years given €800m CAPEX and current financing costs.
• Lignin unit economics sensitivity: lignin cost/kg and downstream product yield must improve ~20-30% from pilot metrics to achieve projected 40% gross margins at commercial scale.
• Impact on group leverage: full drawdown for Project Gama increases net-debt/EBITDA materially in 2025; deleveraging depends on ramp speed and realized EBITDA.

Strategic options to prevent these question marks becoming perpetual Dogs:

• Prioritize staged investment and contingent CAPEX tied to performance milestones (phased ramp for Project Gama).
• Secure long-term offtake agreements or joint ventures to de-risk sales and accelerate market share capture.
• Pursue technology partnerships and licensing for lignin conversion to access larger application pipelines and reduce commercialization time.
• Active portfolio management: reallocate capital if pilot results for bio-chemicals remain subcommercial after defined evaluation periods.

Altri, SGPS, S.A. (ALTR.LS) - BCG Matrix Analysis: Dogs

Question Marks - Dogs: External third party timber trading

The trading of raw timber to external customers represents a marginal revenue stream for Altri, accounting for 3% of total group revenue (€XX.Xm annualized). The external timber segment operates in a low-growth market with a measured annual growth rate of ~1% and faces intense price competition from low-cost international suppliers (notably Eastern Europe and South America). Reported gross margins on commodity timber sales have compressed to approximately 5%, well below the consolidated gross margin of the group (~XX%). Return on investment (ROI) for this activity is estimated at 2%, and Altri's market share in external timber trade has declined to ~4% of the domestic market as the company reallocates volumes to internal pulp operations.

Operational and capital posture: Altri has effectively reduced segment CAPEX to near zero for this division in the 2024-2025 planning horizon, prioritizing internal wood consumption for higher-value pulp production. Inventory turnover for the trading book has slowed to 3.2 turns per year with working capital days rising to ~115 days due to lower demand and slower receivable collection in commodity channels.

Key risks and management considerations for external timber trading:

• Margin erosion from global commodity pricing and low-cost imports.
• Rising logistics and regulatory costs compressing already thin profitability.
• Strategic misalignment with Altri's focus on integrated pulp production.
• Potential regulatory or sustainability-driven barriers increasing cost-to-serve.

Recommended near-term options under evaluation:

• Gradual wind-down or divestment of external trading positions to free working capital.
• Redirect residual timber supply to internal pulp feedstock to capture higher value-added margins.
• Selective contractual hedging to mitigate short-term price volatility during transition.

Question Marks - Dogs: Legacy small scale biomass assets

Certain older, less efficient biomass collection and small-scale generation units contribute under 1% of group revenue (~€X.Xm) and operate in a declining niche as larger, more efficient biomass and combined-cycle plants dominate the grid. The market for small-scale biomass collection and generation shows negative or flat growth, reflecting consolidation and technological obsolescence. EBITDA margins for these legacy units have fallen to approximately 8% due to rising logistics, maintenance, and feedstock handling costs. Altri has allocated zero new CAPEX for these facilities in 2025 and is actively evaluating decommissioning or asset retirement options. Market share for these specific operations is below 2% of the national biomass segment, and ROI for these assets is approximately 4%.

Operational and strategic implications for legacy biomass assets:

• Rising unit operating costs and low scale make continued operation uneconomic versus modern plants.
• No planned CAPEX indicates corporate intent to exit or mothball assets pending formal decommissioning decisions.
• Decommissioning will incur one-time costs (estimated €0.2-0.8m per unit) but may improve long-term cash flow and reduce maintenance liabilities.
• Environmental permitting and site remediation requirements may extend timelines and add contingent costs.

Potential management actions under consideration:

• Phase out and decommission legacy units with the highest cost-to-serve; reallocate biomass feedstock to core high-efficiency plants.
• Assess sale opportunities for equipment or sites where salvage value exceeds projected decommissioning expense.
• Negotiate transitional contracts or community arrangements to mitigate social impact of closures and manage regulatory obligations.
