Marshalls plc (MSLH.L): BCG Matrix [Dec-2025 Updated]

Marshalls' portfolio reads like a strategic pivot: high-growth 'stars' - notably Viridian Solar, Water Management and Mortars & Screeds - are driving top-line momentum and are priority recipients of growth capital, while stalwarts Marley Roofing and Commercial Landscaping act as cash cows funding dividends and the £11m efficiency programme; several question marks (Bricks & Masonry, New Build Landscaping) need targeted investment to regain share, and underperforming dogs (UK quarried stone, Aggregates, Private RMI landscaping) are being exited or de‑prioritised to free up cash for higher-return segments - read on to see how this mix shapes Marshalls' capital-allocation roadmap.

Marshalls plc (MSLH.L) - BCG Matrix Analysis: Stars

Stars

Viridian Solar

Viridian Solar maintains high growth momentum as of December 2025. The business unit achieved 50% revenue growth in H1 2025 and moderated to c.35% year-on-year growth by October 2025, remaining a primary growth engine for the Roofing Products division. Viridian is market-leading in the UK in-roof solar sector with a reported UK market share estimated at 28% in 2025 in its niche segment. Strategic capital allocation from Marshalls has focused on production scale-up, R&D for integrated roofing-solar solutions, and supply-chain resilience.

• Primary growth drivers: Part L building regulation mandatory integrated solar adoption; residential retrofit demand.
• Strategic focus: manufacturing capacity increases, vertical integration with roofing products, targeted marketing to housebuilders and social housing contractors.
• Risks: supply chain constraints for photovoltaic cells, policy/installation standards changes.

Marshalls Water Management

Water Management captured significant share in infrastructure contracts during 2025 and contributed materially to Building Products' 5% revenue increase for the ten months ended October. The unit benefits from long-term government infrastructure spend, SuDS proliferation and climate resilience programmes. Reported YTD revenue to October 2025 rose by c.22% versus prior year, with robust gross margins near 28% and prioritised capital expenditure to expand production lines for specialized water control products and modular attenuation systems.

• Strategic priorities: expand manufacturing capacity, accelerate product certification, win long-term framework contracts with local authorities and utilities.
• Competitive advantages: specialist product portfolio, proven delivery record on large civil projects, strong OEM and contractor relationships.
• Financial impact: prioritized for Transform and Grow capital; higher ROI versus lower-growth building segments.

Mortars and Screeds

Mortars and Screeds delivered resilient performance in 2025, supporting Building Products to reach £150m in revenue for the first ten months. The unit benefited from moderate improvements in national housing build rates and preference for ready-to-use mortars for speed and consistency on site. Reported revenue growth for the unit was c.12% YTD to Oct 2025, with healthy operating margins around 16% and strong ROI on incremental capacity investment. Product sustainability enhancements (reduced embodied carbon mixes) further increased demand from volume housebuilders and affordable housing projects.

• Growth enablers: faster on-site productivity, sustainability product specification, stable supplier contracts.
• Margin drivers: formulation efficiencies, regional plant optimisation and logistics consolidation.
• Outlook: positioned as a high-market-share leader in a recovering housing materials market; continued investment to sustain share.

Marshalls plc (MSLH.L) - BCG Matrix Analysis: Cash Cows

Cash Cows

Marley Roofing remains the dominant market leader in pitched roofing and continues to function as a primary cash cow for Marshalls plc. Despite a modest reduction in revenue during the latter half of 2025 due to a softer market, Marley retained market leadership in concrete tiles and expanded share in clay plain tiles and timber battens during H1 2025. The Roofing Products division, largely anchored by Marley, generated £166.0m in revenue for the ten months to October 2025, providing stable, high-volume cash flows that support dividend payments and accelerated debt reduction.

The Roofing Products division revenue and key metrics (ten months to Oct 2025):

Commercial Landscaping Products represent another central cash-generating unit. This segment delivered steady revenue in a broadly flat landscaping market and accounted for c.42% of Landscaping Products' total revenue for the ten months to October 2025. Landscaping Products reported total revenue of £232.0m for the same period, implying commercial landscaping revenue of approximately £97.4m. The commercial sub-segment showed improving momentum toward the end of 2025 and Marshalls retains high relative market share in UK commercial paving and street furniture.

Landscaping Products segment metrics (ten months to Oct 2025):

Key attributes that qualify these units as Cash Cows:

• High relative market share: Marley and Marshalls' commercial landscaping units occupy leading positions in their core UK markets (top 1-2).
• Low to moderate market growth: Pitched roofing and commercial landscaping are mature segments with limited expansion, classifying them as low-growth markets.
• High and predictable cash generation: Combined, Roofing Products and Commercial Landscaping provided approximately £263.4m in revenue (ten months to Oct 2025) and contribute materially to operating cash flow and free cash flow stability.
• Strategic cash deployment: Cash inflows are earmarked for dividends, debt reduction and funding an £11.0m annualised cost-saving performance improvement plan.

Marshalls plc (MSLH.L) - BCG Matrix Analysis: Question Marks

Dogs - Question Marks

Marshalls Bricks and Masonry faces a competitive and recovering market. Revenue in this segment contracted during 2025 as the business maintained a disciplined pricing strategy to protect margins rather than chasing low-margin volume. While the unit saw sequential improvements in the second half of the year, it remains sensitive to the pace of recovery in the new-build housing sector. The segment requires continued investment to transition toward higher-margin, value-added products under the Transform and Grow strategy. Market share remains under pressure from competitors, placing this unit in a position where its long-term profitability depends on successful strategic execution.

New Build Housing Landscaping seeks to regain lost market share. This segment represents 30 per cent of the Landscaping division's revenue but has been impacted by sector-wide volume reductions and structural overcapacity in the UK supply chain. Marshalls has implemented a performance improvement plan to stabilize the business, which saw revenues remain flat in the four months to October 2025. The company is investing in pricing and customer engagement to win back share in a market that is expected to recover in 2026. High capital requirements for manufacturing optimization make this a classic question mark requiring careful resource allocation.

Key metrics and sensitivities:

• Landscaping division: New Build Housing = 30% of division revenue (explicit).
• Revenue trajectory: Bricks & Masonry contracted in 2025; sequential improvement in H2 2025 observed.
• Short-term revenue stability: landscaping revenues flat over four months to October 2025.
• Capital intensity: high upfront capex required to convert operations to higher-margin product lines and optimise manufacturing - estimated £8-20m per segment depending on scope.
• Market dependency: both segments' profitability highly sensitive to UK new-build housing recovery timing (forecast improvement in 2026).
• Strategic priority: allocate resources to Transform and Grow initiatives that drive product differentiation and margin expansion rather than volume-led share recovery.

Strategic implications for a Question Mark / Dog classification:

• Investment imperative: selective, performance-linked capex to support product transition and reduce unit cost; avoid broad volume chases that compress margins.
• Performance monitoring: tight KPIs on margin per product, order lead times, and customer retention to judge viability of continued support.
• Exit thresholds: pre-defined metrics (market share gains, margin improvement within 12-24 months, ROIC targets) should govern whether to scale up, hold, or divest.
• Customer focus: reclaiming new-build share requires targeted pricing, specification engagement with housebuilders, and marketing of value-added offerings.

Marshalls plc (MSLH.L) - BCG Matrix Analysis: Dogs

UK Quarried Natural Stone processing has been identified for strategic exit. As of October 2025, the Board began formal consultation on exiting this business unit due to sustained losses and fundamental changes in market demand. The segment has experienced persistent manufacturing inefficiencies, rising unit costs and a structural shift in customer preference toward lower-cost, commodity-style paving products. Exiting this business is modelled to improve group operating profit by approximately £2.0 million from 2026, and to reduce annual cash drag associated with plant operations and legacy inventory write-downs.

Aggregates business units continue to underperform within the portfolio. The segment reported a year-on-year revenue decline in 2025 driven by reduced construction activity in some regional markets and intensified pricing pressure from larger, specialized competitors. The Aggregates segment has been a consistent negative contributor to divisional margins and is a focus of the Group's portfolio simplification and capital reallocation. With limited medium-term growth prospects and low relative market share versus national players, management is prioritising capital deployment to higher-return areas such as Water Management and targeted product innovations.

Private Housing RMI Landscaping (domestic repair, maintenance and improvement) has seen subdued consumer demand through 2025 as elevated mortgage rates and cost-of-living pressures constrained discretionary spending on home improvements. This sub-segment, which represented 28% of total landscaping revenue in FY 2024/25, contributed materially to a 96% year-on-year drop in divisional operating profit in H1 2025. The market for premium domestic paving remains low-growth, and Marshalls faces intense competition from lower-cost imports and online DIY channels. Given current macro conditions, the business is a low priority for incremental capital.

The following table summarises key metrics for these low-growth, low-share units and the Board's near-term strategic response:

Primary drivers of underperformance and rationale for divestment or deprioritisation:

• Structural demand shift: end customers moving toward lower-cost, commodity-style products and imports.
• Operational inefficiencies: legacy quarry/processing plant with high unit costs and capex requirements.
• Competitive intensity: national and international low-cost competitors compressing margins.
• Macroeconomic headwinds: high interest rates reducing housing RMI spend and discretionary landscaping projects.
• Strategic focus: reallocate capital to higher-growth, higher-margin segments such as Water Management and sustainable solutions.

Near-term management priorities for these units include accelerated exit planning for quarries, selective closure or consolidation of low-utilisation aggregate sites, SKU rationalisation in domestic landscaping, and redeployment of freed capital to projects forecast to deliver higher return on invested capital (ROIC) and improved group margin profile.
