PHINIA Completes stoba Group Acquisition, Broadening Semiconductor and Aerospace Reach

PHINIA Inc. has completed its acquisition of stoba Group, bringing the German precision-engineering company into a business that has been pushing beyond its traditional vehicle markets and deeper into semiconductors, aerospace and defense. The closing gives PHINIA ownership of 100% of stoba’s equity interests and adds a network of high-precision component, systems and customized manufacturing operations.

The completion announcement from PHINIA said the acquisition expands the company’s footprint across passenger and commercial vehicles, off-highway equipment, industrial applications, capital equipment, semiconductors, and aerospace and defense. PHINIA also said stoba adds another aerospace and defense-certified facility and strengthens its position in semiconductor equipment through high-performance components.

The closing follows the definitive agreement announced June 30. PHINIA did not disclose a final purchase price in Thursday’s completion release. In its second-quarter regulatory filing, however, the company said it expected an approximately $150 million purchase price and planned to fund it through available liquidity. That earlier figure should be treated as the expected purchase price disclosed before closing, rather than a newly confirmed final consideration.

stoba gives PHINIA a broader precision-manufacturing platform

stoba is not a single-product supplier. The group develops and manufactures precision metal components and assemblies, industrializes hybrid applications that combine metal, plastic and electronic parts, and builds specialized machinery using technologies such as electrochemical machining and laser processing. Its markets include commercial vehicles, passenger cars, industrial applications, semiconductors, aerospace, security and defense.

The company has grown from its roots in Backnang, Germany, into an operation spanning five countries and eight locations. stoba said earlier in 2026 that it employed more than 1,000 people, produced more than 100 million parts in fiscal 2025 and generated revenue of €190 million. Those figures give the acquisition meaningful operating scale rather than making it a small technology tuck-in.

For PHINIA, the attraction is partly the manufacturing capability behind those businesses. stoba brings expertise in high-precision engineering, sheet-metal technology, machining, assembly and specialized production systems. PHINIA has said those capabilities can improve supply-chain resilience and widen the range of complex components and systems it can offer customers.

The semiconductor angle is particularly notable because stoba already serves that industry through equipment and manufacturing solutions. Its stoba Systems business describes itself as an established service provider to semiconductor customers, while the broader group lists semiconductors as one of its core markets. PHINIA’s completion release specifically pointed to high-performance equipment components as the route to a stronger position in the global semiconductor industry.

The acquisition adds to an aerospace business PHINIA was already building

The aerospace portion of the deal is an expansion of an existing PHINIA effort, not the company’s first move into the sector. PHINIA formally highlighted its entry into aerospace at the Paris Air Show in 2025 and has since been building engineering, certification and production capacity for civil and military aviation applications.

By July 2026, PHINIA said its engineering center in Blois, France, had become its first site certified to support aerospace programs. The company was also investing in facilities in Gillingham and Stonehouse in the United Kingdom, with certifications planned for the fourth quarter, while supporting new aerospace customer programs. Its aerospace work draws on capabilities already used in demanding propulsion and precision-manufacturing applications, including micron-level machining, advanced coatings, electrochemical machining and laser processes.

stoba widens that platform. Its Kaufbeuren operation, for example, works on sophisticated components, assemblies and systems for aerospace, industrial automation, security and defense, as well as AI robotics. More broadly, stoba lists aerospace, security and defense among the markets served by its precision and manufacturing businesses.

PHINIA said the acquired business adds another aerospace and defense-certified facility to its portfolio. That matters because aerospace manufacturing depends not only on technical capability but also on certified production environments and quality systems. Adding an already qualified site can give PHINIA more capacity to pursue programs without building every capability internally from the ground up.

The roughly $150 million expected price was sized against existing liquidity

PHINIA’s financing plan also provides context for the acquisition. In its second-quarter Form 10-Q, the company said it expected to fund the approximately $150 million purchase price through available liquidity. At June 30, PHINIA reported $370 million of cash and cash equivalents and $1.019 billion of total debt. The company also said its existing cash, operating cash flows and revolving credit facility were expected to support its current and planned operations.

That makes stoba a material acquisition, but one PHINIA had planned to absorb without announcing a dedicated equity financing. The company has framed the purchase as part of a broader diversification effort, using its long-standing strengths in precision manufacturing, fuel systems and industrial engineering to reach markets with different demand cycles from traditional light-vehicle applications.

There is also a portfolio logic to the timing. PHINIA has been adding capabilities outside its core automotive exposure, including its 2025 purchase of Swedish Electromagnet Invest, a supplier of ignition systems and related technologies for natural gas, hydrogen and other alternative fuels. stoba extends that approach in a different direction by adding manufacturing assets and customer exposure across semiconductors, industrial equipment and aerospace-related markets.

The next meaningful financial detail will come when PHINIA reports how stoba is reflected in its consolidated results and purchase accounting. The completion announcement establishes that the acquisition has closed, but it does not provide a final purchase-price allocation, expected revenue contribution or updated earnings guidance tied specifically to stoba. Those disclosures will determine how quickly the broader manufacturing footprint translates into reported sales, margins and cash flow.
