Aston Martin’s creditors have threatened legal action over a £550 million refinancing that moved assets into a newly incorporated Cayman Islands subsidiary and gave new lenders security over parts of the carmaker’s business, escalating a dispute over who would control valuable assets if the 113-year-old company ran into financial trouble.

A group of bondholders owed about £1.3 billion sent Aston Martin’s board a letter before action on Sunday, warning that they could seek proceedings in the UK’s High Court if the company did not address their concerns within days. The creditors want the refinancing unwound and are seeking to prevent the disposal of certain intellectual-property assets.

The dispute centres on Aston Martin’s decision in July to raise £550 million from HPS Investment Partners, the private-credit firm owned by BlackRock. The package comprises a £450 million senior secured term loan and a £100 million delayed-draw facility, with both facilities due to mature in July 2031. The debt is priced at 6.75 percentage points above the Sterling Overnight Index Average, or SONIA.

The financing has given Aston Martin more breathing room. The company said it lifted pro-forma liquidity to about £340 million at the end of June, using the initial £450 million proceeds partly to repay a £170 million revolving credit facility and £20 million drawn under a facility provided by members of the Yew Tree Consortium.

But for existing creditors, the refinancing has raised a different question: whether assets that previously supported their claims have effectively been moved into a structure where new lenders have priority.

Creditors escalate challenge

The bondholders’ letter before action marks an escalation from the opposition that preceded the refinancing.

The creditor group had already objected to the transaction before Aston Martin completed it on 22 July. The lenders described the proposed financing as "extraordinary", arguing that it could leave existing creditors with weaker access to assets while giving HPS security over assets transferred into a new subsidiary.

The creditors are particularly concerned about intellectual property and branding rights. Under the transaction, Aston Martin can draw a further £100 million subject to a deal under which 50.1% of certain non-automotive intellectual property is transferred to Authentic Brands, the US brand-management group whose portfolio includes Reebok and Ted Baker. HPS is also an investor in Authentic Brands, according to people familiar with the arrangement.

The precise scope of the assets involved has become one of the central points of contention.

Aston Martin has not publicly provided a full list of the assets securing the HPS financing. Creditors have argued that the lack of detail makes it difficult for them to assess the effect of the transaction on their existing security and the value of their claims.

Aston Martin has rejected the suggestion that it breached its obligations.

In response to investor questions, the company said the 2029 senior secured notes remain secured by a pledge over the shares of Aston Martin Lagonda Limited, an indirect parent of the newly incorporated subsidiary. It also said that a different newly incorporated subsidiary had been designated an "unrestricted subsidiary" under the indenture governing the notes.

That distinction is important because it goes to the heart of the creditors’ argument: the dispute is not simply over whether assets were transferred, but over the contractual protections available to existing bondholders after the restructuring.

Aston Martin defends refinancing

Aston Martin has presented the transaction as a necessary step to stabilise its finances rather than an attempt to disadvantage existing creditors.

Doug Lafferty, the company’s chief financial officer, said when the financing was announced: "This new £550m debt financing significantly strengthens our liquidity, providing us with both additional resilience and further flexibility to execute our current and future product plans."

The company has since pointed to signs of improvement in its underlying business.

In its half-year results, Aston Martin reported a 68% increase in gross profit and an improvement in gross margin to 34% from 28% a year earlier. Second-quarter free cash outflow fell to £81 million from £201 million, while the company said it was approaching free-cash-flow break-even after adjusting for its half-year interest payment.

Chief executive Adrian Hallmark said the company was "on track to deliver material financial improvement this year compared with 2025", adding that the second half was expected to be stronger.

The improvement has not eliminated the pressure on the balance sheet. Aston Martin continues to contend with high financing costs, US tariffs and weakness in its important Chinese market, while its turnaround depends partly on higher-margin vehicles such as the Valhalla hybrid supercar.

A dispute over the Aston Martin name

The most sensitive part of the creditor dispute concerns the value of Aston Martin’s intellectual property.

The additional £100 million financing is tied to the proposed transfer of 50.1% of certain non-automotive intellectual property to Authentic Brands. The arrangement is understood to concern rights that can be commercialised outside the production of Aston Martin cars, including merchandise and branding.

Creditors have nevertheless raised concerns about the wider value of the Aston Martin intellectual-property portfolio and whether rights associated with the car business could ultimately be affected.

That distinction matters. If the company were to default, creditors would be concerned not only with the physical assets of the carmaker but also with the value of the brand underpinning its ability to sell vehicles.

The company has not said that the rights to use the Aston Martin name on its road cars are being sold to Authentic Brands. Any suggestion that Aston Martin’s automotive naming rights have already been transferred would therefore go beyond what has been publicly established.

The Stroll and HPS connections

The refinancing has also drawn attention to overlapping relationships among some of the parties.

Lawrence Stroll, Aston Martin’s executive chairman and largest shareholder through the Yew Tree Consortium, has interests across the Aston Martin group and its Formula One operation. Aston Martin has separately agreed a £50 million transaction involving the perpetual naming rights of its Formula One team.

HPS, meanwhile, has an investment relationship with Authentic Brands and is providing the new financing.

Scott French, HPS’s co-founder, sits on the boards of both Aston Martin and Authentic Brands, according to corporate filings and company disclosures.

Those relationships have intensified scrutiny of the transaction. There has been no suggestion of wrongdoing by Stroll, French, HPS or Authentic Brands, and the existence of overlapping interests does not itself establish a conflict or breach of duty.

The creditors have, however, questioned whether Aston Martin’s board properly considered its obligations to existing lenders when approving the refinancing.

The legal argument

The bondholders have warned that Aston Martin may have breached provisions of its existing debt documents. They have also raised arguments under section 423 of the Insolvency Act 1986, which can apply to transactions entered into at an undervalue with the purpose of putting assets beyond the reach of creditors or otherwise prejudicing their interests.

Those are allegations, not findings of a court.

The creditors’ letter before action is a procedural step that can precede litigation; it does not mean proceedings have already been issued or that a court has concluded that Aston Martin breached its agreements.

The company has maintained that it is complying with its contractual and disclosure obligations. An Aston Martin spokesperson said:

"The group is in full compliance with its contractual obligations under the bond financing agreements as well as its disclosure obligations."

The creditors are also understood to have proposed an alternative financing package before the HPS deal closed. Aston Martin rejected that proposal, according to people familiar with the negotiations, arguing that it came too late and that the company needed to secure funding on an urgent basis.

What happens next

The immediate question is whether the threatened proceedings will be filed and, if so, whether creditors seek an injunction or other measures aimed at preventing further transfers of intellectual property.

The dispute could ultimately turn on the detailed language of Aston Martin’s bond documentation, the legal status of the subsidiaries involved, and the precise assets transferred or pledged as part of the HPS financing.

For Aston Martin, the stakes extend beyond the courtroom. The company has secured enough new funding to increase its liquidity and repay existing facilities, but the refinancing has also exposed a deeper divide with the investors who already finance the business.

The creditors’ challenge puts a spotlight on a fundamental question for the carmaker: how much of the value of the Aston Martin brand remains available to the lenders who financed the company before its latest refinancing - and how much can be pledged to secure the new financing it says it needs.
