Lubrizol

An Established Business Acquired in 2011

Lubrizol's origins date to 1928. Berkshire completed its acquisition on September 16, 2011, making the company wholly owned. The completion announcement described $135 per share in cash and approximately $9.7 billion of transaction value including approximately $0.7 billion of net debt. [S50]

The distinction between the cash paid for shares and a value including debt matters. It prevents the two measures from being treated as competing descriptions of one identical item.

Berkshire acquired an existing specialty-chemistry operation, not the invention of all its products by the parent. The scientific and customer capabilities had developed within the operating business.

Two Major Operating Areas

The current annual-report description separates Lubrizol Additives and Lubrizol Advanced Materials. Additives include engine and driveline lubricant technologies and industrial specialties. Advanced Materials includes engineered materials and life-sciences-related applications. [S1]

This portfolio should not be reduced to a motor-oil brand. Lubrizol can supply technology and ingredients to companies that formulate and sell the finished oil or another customer product.

Nor is every advanced material a consumer product sold directly under the Lubrizol name. A material may enter another manufacturer's process and reach the user as part of a different branded product.

The actual customer relationship depends on the application. Product formulation, supply reliability and technical support can matter in different proportions across the portfolio.

How an Additive Creates Customer Value

An additive package helps a lubricant meet intended performance requirements. It has to work with the selected base materials and the conditions of the application.

Lubrizol's primary technology descriptions identify packages developed and tested against industry and equipment requirements, with industrial applications extending to areas such as hydraulic and gear systems. [S51]

The commercial role is therefore partly an application problem. The customer is not merely choosing a chemical by weight; it needs a formulation that can be manufactured, documented and sold for its intended use.

Testing and accumulated know-how can make switching more involved than replacing one generic input with another. That does not mean a customer has no alternatives or that a formulation remains suitable forever.

Performance Materials Have a Different Customer Chain

Thermoplastic polyurethane is one example within the materials offering. Its properties can be tailored to applications that need particular combinations of flexibility, durability and processing behavior. [S52]

The material supplier, component producer and finished-product company perform different work. Supplying a polymer used in a medical or consumer application does not make Lubrizol the seller or regulatory approver of every finished device or product.

The same boundary applies to environmental claims. A statement about a particular formulation or application should not be generalized into a claim that every product is recyclable, renewable or suitable for all uses.

The business value comes from meeting a customer's actual requirements at an acceptable total cost, not from attaching a broad scientific label to an otherwise unspecified material.

Research, Qualification and Manufacturing Must Connect

A laboratory formulation has to become a consistently manufactured product. Scale-up, raw-material variation, process control and customer testing can affect that transition.

Research spending is therefore necessary but not sufficient. The resulting technology must be adopted, supplied reliably and priced in a way that supports the full cost of the operation.

Customer support can also reveal new requirements and help adapt existing chemistry. The relationship is not necessarily complete when the first batch is delivered.

Intellectual property can help protect particular technology, while practical know-how and service support the wider proposition. Expiring patents and changing customer needs mean the business has to keep developing rather than depend indefinitely on one historical formulation.

Recent Performance Shows Both Pressure and Recovery

In 2025, Lubrizol revenue was approximately $6.2 billion, down 3%, and pre-tax earnings declined 20.6%. Berkshire identified lower prices and volumes, unfavorable mix, higher manufacturing costs, restructuring and litigation expense among the pressures. [S1]

For the first six months of 2026, revenue increased 7% to approximately $3.4 billion and pre-tax earnings increased 16.5%. The report also described substantial increases in raw-material, energy and supply-chain costs. [S2]

These periods show that technical usefulness does not eliminate price, volume or cost risk. They also prevent an old difficult year from being presented as an unchanged current trend.

Price increases can be a response to rising input costs rather than pure expansion of economic value. Mix and manufacturing performance remain important to the result retained after those costs.

Safety and Environmental Responsibilities

Chemical manufacturing requires safe facilities, trained people, appropriate handling and regulatory compliance. The September 2019 Rouen fire involving Lubrizol and neighboring NL Logistique provides a real historical example of industrial disruption, confirmed by the French Interior Ministry. [S53]

The event should not be used to invent a final legal finding or an unverified current liability figure. It does show why a specialty-chemistry business cannot be evaluated only through the performance of its products in customers' applications.

Reliable operations and community trust require work at the manufacturing sites themselves. Financial ownership does not remove these responsibilities.

Berkshire and OxyChem Boundaries

Rebecca Liebert's responsibilities include Lubrizol and oversight of OxyChem, working with OxyChem CEO Wade Alleman. Berkshire describes OxyChem as a standalone operating business. [S1]

Shared leadership and technical support can be relevant without making the companies identical. Lubrizol's formulation-oriented specialty offerings differ from OxyChem's basic-chemical and vinyl-chain economics.

The parent must assess capital and management across these activities while preserving an accurate view of each business's products, customers and obligations.
