Arcline Investment Management Announces Strategic Investment in American Casting Company for Growth

On December 2, 2025, Arcline Investment Management, a private equity firm focused on growth, revealed its strategic investment in American Casting Company (ACC). Founded in 1974, ACC has become a leader in providing highly engineered investment castings tailored for the aerospace, defense, medical, energy, and specialty industrial sectors. This investment marks a significant step for both companies as they aim to address the increasing demand for complex and mission-critical components in these evolving markets.

American Casting Company specializes in casting intricate geometries from superalloys and other challenging materials. These capabilities are particularly crucial for clients looking to enhance the performance, reduce weight, and increase thermal efficiency of their products. With a strong focus on rapid prototyping and stringent process control, ACC has established itself as a vital supplier for demanding aerospace and defense applications, including high-end aircraft engines and advanced unmanned systems.

As the landscape of manufacturing continues to shift, particularly with OEMs seeking to increase production rates and bring critical component manufacturing back to the U.S., ACC is uniquely positioned to leverage its expertise to meet the rising supply-demand imbalance for high-quality investment castings. The strategic investment from Arcline not only provides financial support but opens up avenues for expanding ACC’s capabilities and capacity, potentially unlocking new growth opportunities.

Chris St. John will remain at the helm as Chief Executive Officer of American Casting Company. St. John expressed enthusiasm about collaborating with Arcline, noting the firm's impressive record of investing in high-caliber aerospace and defense suppliers. He stated, 'Our values are strongly aligned, and we are thrilled to partner with Arcline for ACC's next growth phase.'

To facilitate the transaction, Janes Capital Partners acted as the financial advisor to American Casting Company, ensuring that the investment aligns with the company's long-term strategic goals.

Arcline Investment Management, managing over $20 billion in assets, is dedicated to building industrial platforms that are non-disruptive and market-leading, aimed at sustainable and consistent earnings growth over time. This latest investment aligns with their vision of forging the next generation of industrial manufacturing.
