Alright – here’s your moment of clarity. We asked. They ignored. No weasel-worded press release, no bland corporate statement, no “we take this seriously” copy-paste. Just silence from the people at the very top who ought to be answering for alleged links between Cummins’ Accelera arm and suppliers with links to alleged forced labour.
Below are the exact emails TCAP sent to Cummins senior figures – verbatim – with the dates and deadlines we gave. They were given an opportunity to respond before publication. They chose not to. Read them. Judge for yourself.
Why This Issue Matters
Cummins bangs on about ESG, ethics and transparency in glossy investor decks. Yet when direct, specific allegations linking a supplier to forced labour and potential national-security risks in supply chain tech are presented, the company’s senior leaders go quiet. That silence is an answer in itself.
We’ve reported the supplier material – EVE Energy – and flagged the salient risks. Investors, regulators and the public deserve to know whether the people in charge will respond. They won’t. So we publish the outreach, in full.

Dear Ms. Rumsey,
I am writing to request comment regarding recent concerns raised about Cummins’ Accelera division and its supply chain links to forced labour, particularly in relation to EVE Energy.
As you will be aware, this issue is attracting growing attention from shareholders, the press, and the wider public. Investors including BlackRock, Vanguard, State Street, T. Rowe Price, and Fisher Asset Management have been directly engaged on this matter.
Given Cummins’ stated commitments to ESG principles, transparency, and human rights, I would be grateful if you could provide Cummins’ position on:
- Whether Cummins has conducted due diligence into these alleged forced labour connections.
- What steps, if any, Cummins is taking to review or alter its supplier relationships.
- How Cummins plans to reassure shareholders, employees, and the public that its operations align with stated ethical and sustainability standards.
Your response will be included in forthcoming reporting unless you indicate otherwise.
Thank you for your time, and I look forward to your reply given the gravity of this issue.
Sincerely,
Lee Thompson

Dear Ms. Rumsey,
I am following up on my request of 4 September (unanswered) regarding Cummins’ supply chain and forced labour concerns linked to EVE Energy.
Since then, further allegations and developments have come to light which I would like Cummins to address:
- Forced labour in Tibet – A 2024 Globalworks Lund AB report highlights salient risks of state-imposed labour and forced relocations in Tibetan regions linked to EVE Energy’s operations. What due diligence has Cummins conducted regarding these allegations?
- U.S. national security bans – The Decoupling from Foreign Adversarial Battery Dependence Act, introduced by Senator Rick Scott in February 2025, alongside existing DoD procurement bans, place EVE Energy among Chinese battery firms flagged as potential security risks. Reuters also reported in May 2025 on “rogue” communication devices embedded in Chinese inverters and batteries. How does Cummins reconcile its Department of Defense contracts with this partnership, and what safeguards are in place?
- ESG consistency – Cummins has repeatedly cited its ESG commitments. Given investor sensitivities, has Cummins considered the reputational and legal risks of maintaining this joint venture in light of the above?
I would be grateful if Cummins could provide a statement or response to these specific points. Please note that, absent a reply, my forthcoming reporting will reflect that Cummins has declined to comment on forced labour in Tibet and U.S. national security concerns regarding its partner, EVE Energy.
I request your response by 17:00 BST, Monday 8 September 2025.
Sincerely,
Lee Thompson

Dear Ms. Koski,
I am following up on my previous inquiries regarding Cummins’ supply chain and its links to forced labour, particularly concerning EVE Energy. For context, my reporting on this matter is available here:
- EVE Energy: Batteries Built on Blood, Bullshit and Broken Promises
- EVE Energy Part 2
Given the gravity of these allegations, I would appreciate Cummins’ response to the following:
- Has Cummins conducted due diligence into the alleged forced labour connections within its supply chain?
- What steps is Cummins taking to address these concerns and ensure compliance with ethical standards?
- How does Cummins plan to reassure stakeholders about its commitment to human rights and ethical sourcing?
Your response will be included in forthcoming reporting unless you indicate otherwise.
Thank you for your time, and I look forward to your reply.

Result: No Replies
We set a clear deadline for Rumsey: 17:00 BST on Monday 8 September 2025. We didn’t set Koski a deadline but in the interests of fairness, we waited a couple of weeks. Both have thus far remained silent.
That silence matters. When big-company CSR claims collide with credible allegations of forced labour and national-security risk, the minimum expectation is engagement – a statement, a timeline for review, or even an acknowledgement that they are looking into it. Cummins gave none.
What Do This Mean?
- It removes the option of plausible ignorance. We proved TCAP reached out and invited comment. Their silence is now part of the story.
- It raises investor alarm. You’ve told us you’ve engaged shareholders already; this will feed into their risk calculations.
- It intensifies regulatory curiosity. Public, time-stamped outreach followed by silence is a red flag for watchdogs.
What We Will Do
We’ll update this post if and when Cummins replies. We’ve retained full originals, including SMTP headers and timestamps. We will provide those on request to verified journalists and investigators.
Until then: they will persevere with silence as a strategy. A weak look from weak leaders that are haemorrhaging credibility. At TCAP, we prefer sunlight.
