Transactional due diligence
Working with clients to identify risks and maximise opportunities during mergers, acquisitions, divestitures, streamlining, refinancing, and property transactions.
Property, merger and acquisition leaders
At Ramboll, we understand the criticalities clients face during transactions (both acquisitions and divestitures) including time constraints, voluminous yet often incomplete information, and cost concerns. Our transactional due diligence services are meticulously designed to address these head-on by applying expert judgment and extensive global experience.
For acquisitions, we can draw reliable conclusions from less-than-perfect data, ensuring client decisions are based on thorough and actionable insights. For divestitures, business streamlining and other dispositive transactions, we work with clients to position assets to achieve maximum value. No matter what the transaction or which side of the table, we focus on delivering the most relevant findings within tight timelines, minimising risks and maximising the value of a client’s investments.
Clients choose Ramboll due to our reliability, quality, multidisciplinary knowledge, global footprint, and strong business acumen. Not only do we have strong capabilities in environment, health, and safety, we also have deep technical expertise in specialised areas and sectors such as product risk, climate risk, data centre design, wastewater engineering, and energy solutions. We have a deep understanding of the overall business context in which diligence findings must be considered. Combined, these skills and expert knowledge enable us to provide strategic value protection and creation solutions by offering a unique set of comprehensive and nuanced due diligence services.
Environmental, social & governance (ESG) due diligence
ESG due diligence involves a thorough examination of a company's practices, policies and performance related to environmental, social, and governance factors that affect the value of the company. This evaluation is essential for identifying impacts, risks, and opportunities associated with a company's operations. ESG due diligence findings are leveraged not just as defensive tools, but to proactively inform strategic decisions, impact valuations and drive long-term value.
Each client approaches ESG considerations uniquely in the due diligence process and we craft customised solutions to meet those needs. We are adept at identifying critical ‘red flag’ ESG risks that could impact go-no-go decisions. We uncover opportunities to enhance a company’s value while meeting stakeholder requirements and expectations, and we have the staff, skills and experience to implement these enhancements, ensuring future-proofing and sustained progress.
EHS due diligence for mergers & acquisitions
Environmental, health and safety (EHS) due diligence is a systematic evaluation of a company’s properties, operations and practices relative to contamination, permitting, and regulatory obligations. While this process typically focuses on identification and quantification of risk, a properly scoped diligence plan can identify value creation opportunities. And because no two companies, transactions or clients are the same, a successful process requires a tailored approach that considers myriad factors.
For over 40 years, Ramboll has been a leader and innovator in executing bespoke EHS due diligence programmes to support clients in this high-stakes, time-sensitive arena. From straightforward acquisition, divestiture, refinancing and insurance placement to complex mergers, restructurings, buyouts, public offerings and bankruptcies, Ramboll has the global expertise to achieve clients’ goals, and the tenacity to react nimbly to the dynamic dealmaking environment.
Property due diligence
Institutional property investors, funders, developers, and tenants rely on comprehensive property due diligence to address challenging technical, legislative, and logistical considerations to support investment decisions. They seek clarity, focus, and commercial acumen to achieve smooth and successful transactions, particularly in rapid due diligence scenarios. For brownfields and other sites with a history of industrial use and contamination, successful site redevelopment requires contributions from experts in a variety of technical areas.
Clients benefit from Ramboll’s blend of global presence and local marketplace experience, and our capabilities and breadth of expertise allow us to support projects through the entire lifecycle from acquisition to development to disposition. We have a deep understanding of client needs and objectives, evidenced by many years of valued relationships and repeat client business. Our integrated teams span contaminated land, climate and flood risk, ecology and biodiversity, energy and decarbonisation, and sustainability design, and accreditations. In sale scenarios, we help ensure maximised asset value and liquidity through all transactional stages, from early-stage pre-diligence feasibility appraisals through to de-risking of complex sites, all while matching solutions to client needs.
Technical & operational due diligence/energy assessment
Ramboll has extensive experience in providing technical and operational due diligence, particularly in the data centres and energy sectors. Our data centres and mission critical facilities team is expert at assessing the proposed construction schedules, budgets, and design specifications (including energy supply and resilience measures) of planned, under-construction, and operational data centres against target costs and performance KPIs and advising on considerations and expenditures for achieving those targets and improving ultimate performance.
Within other industry sectors, Ramboll’s global energy and water consulting teams provide similar scope comprehensive technical and operational due diligence assessments, including asset condition, asset planning, procurement, maintenance, and CAPEX/OPEX budgets, with significant experience in biogas, waste-to-energy, wind, conventional power generation and transmission, and water and wastewater treatment.
Commercial due diligence
Through the in-depth assessment of market dynamics, competitive positioning, and financial health, commercial due diligence evaluates the viability and potential of investment opportunities. The primary goal is to deliver detailed insights that empower clients to make well-informed decisions, minimise risks, and maximise transactional value.
Ramboll is a trusted commercial due diligence advisor to clients, particularly in the energy, transport, and building sectors. Our team identifies and assesses market and commercially-driven value drivers, linking them to the financial model and connecting that across all workstreams. Our clients benefit from seamless collaboration across commercial, technical, environmental, and ESG aspects. The result is an efficient process that supports clients to secure a fair buy-side valuation and in diligently managing the sell-side process.
Climate risk due diligence
Ramboll provides detailed assessments of physical and transition climate risks that may materially impact asset values and business operations. Our integrated approach identifies climate-related vulnerabilities from the present through the expected holding period and beyond, ensuring investment decisions reflect the full range of climate-related financial risks. We leverage HazAtlas, our proprietary climate risk modelling platform, for precise, location-specific assessments of physical climate hazards including flooding, extreme weather, sea-level rise, and temperature variations across future climate scenarios.
Our climate risk assessments leverage in-house, sector-specific expertise in adaptation planning and risk management to identify value protection and creation strategies. Our adaptation engineers design resilient infrastructure, and management consulting teams evaluate risk management practices against climate vulnerabilities to pinpoint critical gaps and enhancements. We recommend targeted mitigation measures, operational improvements, and strategic adaptations that protect asset values and unlock competitive advantages through improved resilience and sustainability. Whether supporting acquisitions, divestiture, or portfolio optimisation, we deliver strategic intelligence to navigate an increasingly climate-conscious investment landscape while positioning assets for long-term resilience and value creation.
Product/food safety due diligence
Product and food safety due diligence is crucial for ensuring that transactions in the food, consumer goods, and industrial sectors meet regulatory requirements and protect consumer health. Companies involved in manufacturing, distribution, and retail of food products, consumer and industrial goods need these services to mitigate risks and guarantee product integrity. Few firms possess the specialised expertise to offer comprehensive due diligence in these areas, making it a critical service to ensure compliance and safety in transactions.
