The Novamont Takeover: How Losses, Litigation and Strategic Control Ended in Eni’s Hands

When Eni S.p.A. completed the full takeover of Novamont S.p.A. in October 2023 through subsidiary Versalis S.p.A., the deal was presented as a strategic milestone in green chemistry.

But behind the official narrative lies a more complicated story: years of losses, shareholder conflict, high-stakes litigation, and an eventual consolidation that placed one of Europe’s best-known bioplastics pioneers fully under the control of a fossil-fuel major.

From Green Pioneer to Corporate Capture

For years, Novamont was promoted as an innovation champion in biodegradable materials, circular economy packaging, and renewable chemistry. It cultivated an image as a forward-looking industrial success story and benefited from strong institutional credibility.

Yet by 2023, independence had ended.

Eni disclosed in its 2023 Form 20-F that it acquired the remaining 64% of Novamont on 18 October 2023, having already owned 36%. The filing states consideration for the remaining stake was €404 million, together with the assumption of €207 million in net financial liabilities. Eni also assigned a €227 million fair value to its pre-existing stake and initially recognized €19 million of goodwill.

The numbers show a major transaction. The deeper question is why it became necessary.

Matrìca: The Warning Sign

Long before the takeover, serious cracks had already emerged through Matrìca S.p.A., the Sardinia-based venture linked to Novamont and Versalis interests.

In Novamont’s own 2020 reporting, Matrìca was described as producing negative economic results, requiring substantial financial support, and struggling with slow market development despite technical progress.

The same report stated Novamont had not injected additional financial resources and that shareholder disputes had effectively pushed Novamont out of management.

That is not the language of a thriving strategic partnership. It is the language of industrial breakdown.

The €367 Million Legal War

Novamont’s 2020 disclosures also described arbitration proceedings launched in 2018 by Versalis and Eni concerning alleged breaches of provisions in a 2011 framework agreement tied to Matrìca.

Claims were disclosed at approximately €367 million, while Novamont reported counterclaims of around €172.6 million.

Whatever the final legal outcome, these are extraordinary figures in the context of a company promoted as a sustainability success story.

When partners in a flagship green venture are fighting over hundreds of millions of euros, the public deserves to ask what went wrong.

The Takeover That Solved Multiple Problems

By 2023, the acquisition of Novamont offered Eni several advantages at once:

• full control over strategic biomaterials technology
• removal of minority shareholder complexity
• possible closure of a long-running dispute cycle
• integration of patents, brands, and know-how into Versalis
• repositioning of Eni’s chemicals portfolio under a greener narrative

In that sense, the Novamont deal may have been more than an acquisition. It may also have been a strategic clean-up operation.

The Accounting Fog

Eni stated that the purchase price allocation was still provisional at year-end 2023, meaning values assigned to acquired assets and liabilities were not yet final.

That matters because Novamont’s core value likely rested in intangible assets such as:

• patented materials technology
• industrial know-how
• licensing potential
• trade names
• customer relationships

Where commercial performance has been under pressure, the valuation of such assets becomes a legitimate area for scrutiny.

Later Versalis disclosures indicate aspects of the allocation were subsequently refined. That may be normal under IFRS rules — but it also means the original headline numbers did not tell the full story.

Public Money, Private Consolidation?

Novamont spent years associated with Europe’s green transition narrative, innovation funding ecosystems, and industrial sustainability policy.

Its final destination was full absorption by one of Europe’s largest traditional energy groups.

That trajectory raises uncomfortable but fair questions:

• Did public support build an independent champion — or assets later consolidated by an incumbent giant?
• Were commercial weaknesses visible earlier than acknowledged?
• Did governance failures at Matrìca accelerate the end of independence?
• Was the takeover the solution to problems few wanted publicly discussed?

Why This Story Matters

Novamont is not just one company. It is a case study in how celebrated green ventures can evolve behind closed doors:

• optimism followed by losses
• partnerships followed by disputes
• innovation narratives followed by consolidation

For investors, policymakers and taxpayers, that pattern matters.

Conclusion

Eni may yet create value from Novamont. But the route to ownership appears to have passed through operational strain, litigation, governance conflict, and complex deal accounting.

The official story is strategic growth.

The harder story is how a flagship green pioneer lost its independence — and who benefited when it did.
