Manufacturers are moving forward with acquisitions made at the end of 2025 in an effort to expand their operations, broaden their product offerings or gain a stronger presence in the United States amid tariff uncertainty.

Here are some of the major deals that happened in late December.

Samsung Biologics’ U.S. subsidiary has agreed to spend $280 million on a drug production site in Rockville, Maryland, a move that would expand its global manufacturing footprint to the country for the first time.

The deal, expected to close by the end of March, includes two Rockville manufacturing plants owned by U.K.-based GSK, with a combined 60,000 liters of drug substance production capacity, according to a Dec. 22, 2025, news release.

Samsung Biologics said it plans to retain the site’s existing 500 workers and make additional capacity and technology investments to bolster its U.S. supply chain. The deal, if approved, would give the company a 100% stake in Human Genome Sciences, which GSK acquired for $3.6 billion in 2012.

John Rim, CEO and president of Samsung Biologics, called it a “landmark acquisition” that allows the company to deepen its collaboration with U.S. stakeholders. The Rockville location would add to the contract manufacturer’s 785,000 liters of production capacity across five plants in South Korea.

The divestiture would allow GSK to improve its balance sheet and pursue other deals that better align with its overall strategy. In September, the company pledged to invest $30 billion in research and development and manufacturing in the U.S. over the next five years.

Pittsburgh-based Howmet Aerospace has agreed to acquire Consolidated Aerospace Manufacturing, a designer and maker of fittings, fasteners and other aircraft hardware, from Stanley Black & Decker for $1.8 billion in cash.

The deal, if approved, would bolster Howmet’s revenue by nearly $500 million and provide a “significant tax benefit” for fiscal year 2026, according to the company’s December 2025 news release. It is expected to close by the end of June.

John Plant, chairman and CEO of Howmet, called the acquisition a “major step” on its journey to expand and diversify its fastener portfolio, saying CAM’s “brands, engineering prowess, and deep customer relationships are a perfect complement to our existing business.”

The deal includes a number of assets, including production plants and offices across California, Connecticut, Illinois and Ohio, according to CAM’s website. More than 1,400 employees work for the company.

Stanley Black & Decker acquired CAM for $1.5 billion in early 2020 in an effort to diversify its portfolio and gain access to major aerospace customers such as Boeing and Airbus. The divestiture will now allow the tools and outdoor equipment company to “significantly reduce” its debt and pursue other “value-creation opportunities,” President and CEO Chris Nelson said in a recent statement.

Deere & Co. has agreed to buy Tenna, a provider of equipment tracking and management software for construction contractors, for an undisclosed amount.

The deal, if approved, would expand Deere’s technology services portfolio as companies look to gain data-driven visibility and insights into their operations.

Tenna, New Hope, Pennsylvania-based holding of the Conti Group, leverages sensors, cameras and other internet-connected technology to give contractors a “near real-time, full-picture view” of their equipment and workflows, allowing them to identify trends and maintenance needs more efficiently, according to a news release.

The acquisition is expected to close next month. More than 650 businesses use the company’s platform, according to Tenna’s website. The technology company will continue to operate independently and focus on growing its mixed-fleet, customer-focused business model, according to Deere.
