Silgan Shares Rise 6% After $3.4bn Trivium Packaging Deal with AIP

Silgan Holdings (NYSE: SLGN) has agreed to buy Trivium Packaging, valuing the European metal packaging maker at about $3.4bn including debt, and its shares rose about 6% today. Silgan, based in Norwalk, Connecticut, makes metal containers, closures and custom plastic containers.

Silgan closed at $40.06, up 5.98% from Friday’s close of $37.80, within a day range of $38.615 to $41.145. The shares remain 12% below their close on the 15th of July, though above the 52-week low of $33.70 set on the 5th of October.

Silgan and funds managed by American Industrial Partners (AIP), a private equity firm, announced the all-cash agreement before the US open today. Trivium will be merged with Silgan’s metal containers and food and beverage flat cap closures units. The new business, Silgan Metal Containers & Closures, will be 60% owned by Silgan and 40% by AIP, and is valued at $7.3bn.

Trivium is a Netherlands-based metal packaging maker with 57 locations and about 7,200 employees, and had revenue of about $3bn in 2025. Its sellers are majority owner Ontario Teachers’ and Ardagh Group, which holds about 42% and is exiting.

The $3.4bn is about 85% of Silgan’s pre-deal market value of roughly $4.0bn, but it is not Silgan’s cost. AIP is investing about $1bn for its stake, and Silgan expects about $2.3bn of cash proceeds. Silgan’s 2025 net sales were about $6.5bn.

Chief executive Adam Greenlee told analysts the geography is the attraction:

Trivium is much more focused and has a much larger presence in Europe. So you kind of get that geographic benefit of both, and as we think about our increasingly global customers, we think that’s a great way to serve a global customer base.

Davidkhanian, an analyst at eMarketer, said the combination makes sense because it creates opportunities to take costs out and improve margins without relying on a rebound in demand.

Closing is not expected until mid-2027, subject to regulatory approvals and works council consultations. Silgan reports third-quarter results before the US open on the 29th of October, with consensus earnings per share of $1.25.
