Mitie Acquires Forest Group Holdings to Expand Refrigeration Capabilities

Financial lens: price, multiples and what looks fair

On the numbers disclosed, Forest delivered £7.6m of revenue and £0.5m of EBITDA in the 12 months to 31 January 2025. That implies an EBITDA margin of approximately 6.6%. Upfront consideration of £4.5m equates to roughly 9x trailing EBITDA. If the full £7.0m is paid, the multiple rises to about 14x.

Is that rich or reasonable? For a niche, critical-service capability with strong blue-chip customer exposure and clear cross-sell potential, a mid-teens multiple on a full earn-out feels defensible. The performance-linked structure de-risks the price. Earnings accretion or integration cost guidance is not disclosed. Funding from existing facilities suggests no balance sheet strain.

What success looks like after completion

• Self-delivery at scale – fewer subcontractors, tighter quality control and better margin capture over time.
• Data-driven maintenance – integrating refrigeration into BMS should improve uptime, cut energy use and enable predictive maintenance.
• Cross-selling – leverage Mitie’s security and hygiene relationships in retail and supermarkets to win refrigeration maintenance and upgrade projects.
• National rollout – expand Forest’s operating model beyond its Midlands, Northern England and Scotland footprint.

Key risks and watch-outs for investors

• Integration and retention – keeping Forest’s 40 specialist engineers is vital to service continuity and growth.
• Execution on national scaling – moving from regional strength to national coverage requires investment and careful scheduling.
• Contract visibility – contract lengths, renewal rates and pipeline details are not disclosed.
• Margin improvement – current EBITDA margin of c.6.6% leaves room for operational gains, but delivery will depend on self-delivery benefits and mix.

Management’s messaging and tone

Mitie emphasises unlocking self-delivery in refrigeration and enhancing data-led monitoring through BMS integration. Forest’s leadership frames the move as a growth platform with stronger capabilities and support. It reads as a strategically motivated bolt-on, rather than a scale-driven land grab.

Bottom line: small bolt-on, sensible strategic leverage

This is a modest-sized acquisition that slots neatly into Mitie’s Technical Services stack. The economics look reasonable given the capability uplift, cross-sell potential and performance-linked earn-out. Forest’s customer set enhances credibility in sectors where refrigeration is mission critical.

Near-term financial impact is unlikely to be transformational, but the strategic optionality is the appeal. If Mitie can scale self-delivered refrigeration across its retail, distribution and hospitality accounts, the value will come from improved margins, stickier client relationships and incremental project work.

Quick jargon check

• EBITDA – earnings before interest, tax, depreciation and amortisation, a proxy for operating cash earnings.
• M&E – mechanical and electrical services, the core engineering disciplines in building operations.
• HVAC – heating, ventilation and air conditioning.
• BMS – building management systems, software that monitors and controls building assets for performance and energy efficiency.
• Self-delivery – providing services with in-house teams rather than subcontractors.
