Industry Brief, September 3, 2026: PMI warnings, NVIDIA buys Hugging Face, robot parts

By MillBrief Editorial · September 3, 2026 · Retrospective edition, published September 23, 2026

This is a retrospective edition. The brief did not run on September 3, 2026; we wrote it on September 23, 2026 using only reporting that was published on or shortly before September 3, 2026, and it makes no forecasts.

This is a retrospective edition covering September 3, 2026, using only reporting published on or up to two days before that date. Today: a factory survey that is still growing but flashing early warnings, a $12.9 billion deal for the Hugging Face AI platform, a close look at how the FCC robot rules meet a supply chain built on Chinese parts, and a big automation supplier reorganising around AI. Our own words, links to the original outlet, vendor numbers labelled as vendor numbers.

August PMI: still expanding, but orders slow and lead times stretch

Manufacturing Dive reports that the Institute for Supply Management’s manufacturing PMI was 54.6% in August, a full point below July but the eighth straight month of expansion (above 50%). New orders fell 3 points to 53.7%, the order backlog dropped 3.2 points to 51.8%, imports dropped 3.2 points to 52.5%, and employment eased 1.6 points to 51.2%. Prices held at 71.1%, the same as July. Supplier deliveries slowed for a ninth month, at 59.3% (in this index, above 50% means slower).

Of the negative comments from respondents, 57% mentioned pricing volatility, 46% longer lead times, 30% the Iran war and 29% tariffs. Susan Spence, who chairs ISM’s survey committee, said this was the first month she had seen drops of more than three points in three important areas, and that she was starting to see warning signs. The S&P Global US manufacturing PMI was 53.9%, unchanged.

Why it matters: Two readings matter for anyone quoting automation now. A prices index at 71.1% means input prices are still rising, and slower supplier deliveries plus the lead-time complaints suggest equipment may take longer to arrive. Ask for delivery dates in writing and allow slack in the schedule. Softer new orders are also a reason to rerun your payback math at a lower volume before committing.

NVIDIA agrees to buy Hugging Face for $12.9 billion and promises it stays open

The Robot Report reports that NVIDIA is acquiring Hugging Face, the open platform for sharing AI models and datasets, for $12.9 billion. NVIDIA CEO Jensen Huang said the platform will remain open to the whole ecosystem, that developers will keep choosing their own models, clouds and hardware, and that NVIDIA compute will not be required to build on or deploy through it. He put its use at more than 18 million developers sharing more than 3 million models, 500,000 datasets and 1 million applications, with more than 200,000 companies on the platform.

The robotics link is direct. In July the two companies added NVIDIA’s Isaac GR00T 1.7 model and Isaac Teleop framework to LeRobot, Hugging Face’s open-source library for robot datasets, models and policies. NVIDIA says it is the largest contributor of data and open models to the platform, with more than 500 models and 250 datasets. Hugging Face’s founding team expects to stay.

Why it matters: Once the deal closes, LeRobot, the open robot-learning library, will sit on a platform owned by NVIDIA, which also sells edge AI computers for robots, such as Jetson. The promises of openness are public and specific, which is useful, but they are promises. If a vendor’s learning-based system depends on open models or LeRobot tools, ask what it would do if licensing or hardware support changed, the same supplier-risk question on our integrator list.

Nikkei: the FCC robot rules collide with a supply chain built on Chinese parts

Nikkei Asia, republished by KrASIA, reports that US companies are still working out what the FCC’s July move to put advanced mobile robots on its Covered List means in practice, with exemption rules unclear. Jeff Burnstein of the Association for Advancing Automation called navigating it a day-to-day matter. The ban does not affect existing models already sold in the US, and new robots assembled in the US face rising domestic-content thresholds that reach more than 75% in 2029.

The hard part is components. Citing an August report from Gavekal Technologies, the article says actuators typically make up 40% to 60% of a humanoid’s hardware bill of materials, and that China also supplies most of the batteries, lidar and motor controllers used to build robots. Michael Perry of Persona AI said actuator, ball screw and battery supply is already tight. An internal A3 review found that 28 of 31 US university-led research papers using humanoid or quadruped robots used Unitree machines. Views split: Standard Bots CEO Evan Beard praised the rules and urged the same for fixed robot arms, while Burnstein warned that costs for startups will rise and availability may fall.

Why it matters: Existing models are not affected, so for a buyer the nearer-term effect is more likely to show up in the price and lead time of new robots. The article describes US robot makers relying on Chinese sensors, joints, motors and batteries, so a US-built robot can still carry that supply risk. Ask suppliers where the key components come from and how long spares take, and keep that in your hidden-cost list.

Siemens folds four automation businesses into one from October

Drives & Controls reports that Siemens will combine Factory Automation, Motion Control, Process Automation and Customer Services into a single Automation organisation from October 1, 2026. Rainer Brehm, currently COO and CTO of the automation operation in Siemens Digital Industries and a former CEO of its Factory Automation business, becomes president of the new unit and reports to Cedrik Neike, the board member who runs Digital Industries.

Siemens presents the move as part of its “One Tech Company” strategy. Neike said the future of industry lies where automation, software and AI meet, and Brehm said the aim is to advance AI-enabled autonomous production for customers.

Why it matters: If your plant runs on Siemens controls, drives or service contracts, the article describes no customer-facing changes, but a reorganisation is a good moment to confirm your local support contacts and any service agreements that name the old units. The bigger signal is that one of the largest automation suppliers now sells controls, motion and service as one business with an AI pitch. That is worth remembering when you compare integrator rates against a supplier-led package.
