Two Nordic engineering giants just redrew the map of Europe's consulting industry with a merger announcement that creates an 8 billion Swedish krona powerhouse and signals a new chapter in the battle for industrial and energy infrastructure dominance across Scandinavia.

On Saturday, September 7, Multiconsult and Rejlers unveiled plans to combine in a merger of equals, forming Multiconsult Rejlers—a pan-Nordic multidisciplinary consultancy group with nearly 8,000 employees and operations across Norway, Sweden, Denmark, Finland, and beyond. The combined entity will be dual-listed on Nasdaq Stockholm and Euronext Oslo Børs, positioning it as one of the region's largest independent consulting firms.

The deal reflects a broader consolidation wave sweeping through Europe's fragmented engineering consulting market, where mid-sized firms are banding together to compete against global giants like Jacobs, AECOM, and Wood for increasingly complex infrastructure and energy projects.

Complementary Footprints Drive the Deal

Multiconsult, headquartered in Oslo, brings strength in Norway's energy, transportation, and construction sectors, with deep expertise in offshore oil and gas projects, hydroelectric power, and urban infrastructure. The firm's client base includes Norwegian state-owned energy companies, municipalities, and major construction firms executing large-scale public works.

Rejlers, based in Stockholm, complements that footprint with a dominant presence in Sweden and Finland, where it serves industrial clients, telecom operators, and defense contractors. Rejlers' portfolio spans electrical systems, automation, and building services, with particular strength in manufacturing and heavy industry—sectors where Multiconsult had less penetration.

The merger creates a firm with approximately SEK 8 billion in combined annual revenue (roughly $735 million USD at current exchange rates), nearly 8,000 employees, and a market capitalization that positions it among the top three Nordic consultancies. More importantly, the deal eliminates geographic overlap while layering complementary technical capabilities, allowing the combined firm to bid on larger, multi-country contracts that neither could pursue independently.

Under the merger terms, each Multiconsult share will receive 0.9725 new Rejlers Class B shares. The transaction is structured as a cross-border merger, expected to close by mid-2027 pending regulatory approvals and shareholder votes.

Energy Transition and Defense Spending Are the Real Drivers

The timing of this merger is no accident. Europe's energy transition and surging defense budgets are creating unprecedented demand for engineering consulting services, and firms with cross-border capabilities are winning the most lucrative contracts.

The Nordic region sits at the epicenter of both trends. Norway is racing to electrify its offshore oil and gas platforms, develop floating wind farms, and upgrade transmission infrastructure to handle renewable energy surges. Sweden and Finland are expanding nuclear capacity, modernizing aging grids, and building new data centers to support the AI computing boom.

Defense spending is another tailwind. Finland and Sweden's recent NATO accession has triggered billions of dollars in infrastructure upgrades—military bases, secure communication networks, and hardened facilities designed to withstand Baltic Sea tensions with Russia. Rejlers already serves defense contractors and government agencies on sensitive projects; Multiconsult's infrastructure expertise will allow the combined firm to capture a larger share of this growing market.

Multiconsult Rejlers executives highlighted these opportunities in their merger announcement, noting that the combined firm will have "a particularly strong presence in energy and industrial markets, as well as defense-related projects." That positioning is deliberate: European governments are prioritizing domestic or regional firms for critical infrastructure contracts, and a pan-Nordic consultancy with dual listings and local talent in every major market has a competitive edge.

Margin Expansion Is the Test

The financial logic behind the merger hinges on margin improvement. Multiconsult and Rejlers currently operate with a combined adjusted EBITA margin of approximately 6.7 percent, below the 10 percent target the merged entity is aiming for. Achieving that goal without weakening local client relationships—the lifeblood of consulting firms—is the challenge.

Consulting mergers often struggle to realize synergies because client loyalty is personal and project-based. Engineers and project managers who leave after a merger can take clients with them, eroding the revenue base the deal was meant to expand. Multiconsult Rejlers will need to thread a delicate needle: centralizing back-office functions, rationalizing IT systems, and consolidating supplier contracts to cut costs, while preserving the local "franchises" that generate billable hours.

The firms are targeting SEK 120 million in annual synergies, primarily from shared infrastructure, procurement leverage, and eliminating duplicate corporate functions. But analysts are watching whether the margin target is achievable without attrition among senior consultants or a drop in utilization rates—the percentage of billable time consultants actually charge to clients.

Nordic Consolidation Isn't Stopping Here

This merger is the latest in a string of Nordic consulting deals that reflect the region's maturing market. Rejlers itself has been an aggressive acquirer in recent years, buying smaller firms to expand its geographic reach and technical capabilities. The Multiconsult tie-up represents a step change in scale, but the strategy remains consistent: grow through M&A, target sectors with strong tailwinds, and build capabilities that justify premium pricing.

Industry observers expect more deals to follow. The Nordic consulting market is still fragmented, with dozens of firms in the SEK 500 million to SEK 2 billion revenue range—big enough to have specialized expertise, but too small to compete for the largest contracts. As major infrastructure projects grow in size and complexity, clients increasingly prefer one-stop-shop consultancies that can handle design, engineering, project management, and commissioning under a single contract.

That trend favors consolidation. Firms that don't scale risk becoming niche players or acquisition targets themselves. Multiconsult Rejlers' combined footprint and dual-listed structure position it as a consolidator, not just another merger participant. Expect the firm to continue acquiring smaller consultancies in Denmark, Germany, and the Baltics to fill capability gaps and strengthen its pan-European presence.

What This Means for the Industry

For clients, the merger presents both opportunities and risks. A larger firm can staff bigger projects, bring deeper technical expertise, and offer more cross-disciplinary capabilities. But clients also worry about losing the responsiveness and agility that smaller, regional firms provide. Multiconsult Rejlers will need to prove it can maintain local relationships while delivering the scale advantages that justify the merger.

For employees, the integration will define career trajectories. Engineers at both firms will face questions about leadership roles, office locations, and which corporate culture wins out when decisions conflict. The firms have promised minimal layoffs, but in consulting mergers, the real attrition happens six to twelve months after close, when high performers leave for competitors or start their own boutique firms.

For competitors, the merger raises the stakes. Smaller Nordic consultancies now face a stronger rival bidding on the same projects, while global firms like Jacobs and AECOM will see Multiconsult Rejlers as a credible regional threat worth watching.

The SEK 8 billion valuation may not sound massive by global standards, but in the context of Nordic engineering consulting, this is a landmark deal. It's a bet that the future belongs to firms with scale, cross-border capabilities, and exposure to structural growth themes like energy transition and defense modernization.

Multiconsult Rejlers just became the largest independent Nordic consultancy with a clear path to 10 percent margins and the financial firepower to keep buying. Whether it delivers on that promise will determine if this merger becomes a blueprint for the industry or a cautionary tale of integration gone wrong.
