The U.S. manufacturing sector faced ongoing challenges in September 2024, with data indicating continued contraction amid economic uncertainty. However, major new factory announcements during the month also pointed to pockets of growth.

Reports from the Institute for Supply Management (ISM) and S&P Global showed that manufacturing activity declined for the sixth straight month based on measures like the Purchasing Managers Index (PMI). New orders, production, employment, and exports remained weak across most industries as high inflation, rising interest rates, and fears of a potential recession weighed on demand.

However, even with the downbeat numbers, September saw billions invested in new manufacturing facilities and expansions. Companies like Siemens Mobility, NanoGraf, and Novartis made large commitments to new production plants, underscoring confidence in strategic American industries.

The conflicting signals of broad declines yet ongoing investment paint a complex picture of the manufacturing landscape. As the sector aims to stabilize after months of contraction, the rest of the year will indicate whether demand and output can recover or if more turbulence lies ahead. However, the wave of new factories shows that manufacturing innovation continues, albeit unevenly, even amid challenging times.

A Month in Data

The ISM Manufacturing PMI registered 47.2 percent in September, indicating contraction for the sixth consecutive month. Key sub-indexes like New Orders (46.1 percent), Production (49.8 percent), and Employment (43.9 percent) remained in negative territory. This points to ongoing weaknesses across demand, output, and jobs. Backlogs contracted as well.

The S&P US Manufacturing PMI posted 47.3 in September, down from 47.9 in August, signaling faster deterioration. Key trends include the largest drop in production in 15 months, the steepest drop in new orders since June 2023, and renewed job losses amid falling output.

The reports agree that manufacturing contracted further in September, with new orders and employment declining notably. Production is more mixed but still weak in most areas. While price increases may be peaking, costs are still burdensome for manufacturers.

What the Data Means

The ISM and S&P Global PMIs both indicate the manufacturing sector contracted further in September, pointing to generalized weaknesses in demand and output. 

The ISM Manufacturing PMI slipped marginally to 47.2 percent while the S&P gauge posted a faster decline to 47.3. Both signal the sixth straight month of deterioration for manufacturing. The reports largely agree with measures like new orders, production, and employment in negative territory. Backlogs also dropped sharply.

This data indicates manufacturers face substantial near-term headwinds around spending pullbacks from clients amid high inflation, rising interest rates, and economic policy uncertainty tied to the November 2024 presidential election. Hesitant customers have cut back on new orders and investments, forcing manufacturers to reduce production and employment. Excess capacity is apparent in shrinking backlogs.

While input cost increases may be moderating slightly, prices for raw materials and transportation remain historically high, squeezing manufacturer margins. Weaker global demand, especially from Europe, is also limiting export opportunities.  

The September reports reaffirm a manufacturing sector struggling to find its footing in an uncertain environment. A cloudy economic outlook continues forcing cautious moves from both manufacturers and their customers. Stabilization remains elusive six months into contraction, pointing to potential lingering effects ahead.

New Factory and Manufacturing Announcements

While the manufacturing sector contracted broadly in September, major new facilities show pockets of ongoing growth and investment. Significant announcements included:

Siemens Mobility’s $60 million high-speed rail production facility in Horseheads, New York 

Siemens is building North America’s first plant dedicated to high-speed rail manufacturing. The 300-job facility will produce trainsets for the upcoming Brightline West bullet train connecting Las Vegas and Southern California.

NanoGraf’s $175 million silicon anode battery material factory in Flint, Michigan

NanoGraf’s plant aims to produce enough silicon anode material to supply up to 1.5 million electric vehicles annually. The expansion will play a key role in strengthening domestic EV battery supply chains.  

Novartis’ $200+ million investment in two new radioligand therapy (RLT) facilities

Novartis commenced construction on new RLT production plants in Indianapolis and California to meet the rising demand for these advanced cancer treatments.

S&C Electric Company’s 275,000-square-foot grid resilience facility in Illinois 

S&C opened this new plant to boost its capacity to supply advanced technologies and solutions for modernizing and hardening electrical grids.

Aerospacelab’s satellite manufacturing facility in Torrance, California

AerospaceLab’s state-of-the-art plant aims to produce two satellites per week on average. The 35,000-square-foot facility will support U.S. aerospace customers and programs.

The breadth of critical industries investing in new American production capacity underscores areas primed for growth despite recent setbacks. Manufacturing retains pockets of strength amid vulnerability.

Future Outlook

The near-term outlook for manufacturing remains murky amid persistent economic uncertainty. New orders and employment may continue contracting over the next few months as hesitation linked to the November election caps demand and output. Many firms are delaying major decisions until the political environment stabilizes. 

However, the election outcome and potential for lower interest rates could reaccelerate spending and investment, serving as post-election growth drivers. Infrastructure initiatives and green energy incentives may also bolster manufacturing. Economists expect a gradual demand recovery allowing production and hiring to stabilize.

Several promising longer-term trends may propel future expansion as well. The industry continues shifting towards high-technology and sustainable manufacturing, which is evident in September’s major facility investments. Areas like electric vehicles, battery production, renewable energy, aerospace, and communications tech are primed for growth. 

With both current hurdles and emerging opportunities, U.S. manufacturing faces a complex balance ahead. While recovery timelines remain uncertain, American production retains fundamental strengths around innovation, technology, and market-leading capabilities that can override near-term contractions. The resilience and production announcements this past month reinforce manufacturing’s overall staying power.
