East Penn Manufacturing Company
East Penn Manufacturing Company was founded in 1946 by DeLight E. Romesburg Sr. near Lyon Station, Pennsylvania, as a small battery-rebuilding shop. The company became a vertically integrated battery producer, controlling lead smelting, plastic molding, and distribution through its own fleet—one of the largest private trucking operations in the US. The Romesburg family has retained full ownership through three generations, with the chairman's role passing to Robert F. Romesburg. The family office structure focuses on reinvesting profits from the core battery business into capital-intensive expansion projects, including a multi-year, $100M+ expansion of its Pennsylvania facility announced in 2022. Deployment targets include advanced lead-acid and lithium-ion battery technologies, industrial automation, and renewable energy storage infrastructure. The firm operates primarily in North America but exports to 100+ countries. East Penn is the largest single-site battery recycling facility in the world, recovering 99% of material from spent batteries. The family office maintains philanthropic structures through the East Penn Manufacturing Foundation, which supports education and community development in Berks County. In 2025, the firm broke ground on a new logistics hub in Pennsylvania, expanding its warehouse capacity by 25% to meet growing demand for energy storage products. The structural differentiator is the firm's complete vertical integration: from lead smelting to retail distribution, every stage sits under family control. This insulates capital deployment from supply-chain disruptions and allows multi-decade reinvestment timelines that public companies cannot match.

Frequently asked questions
Who runs investment decisions at East Penn Manufacturing's family office?
The Romesburg family manages capital allocation through the chairman, Robert F. Romesburg, and the president and CEO, Chris Romesburg. Investment decisions are made with a multi-generational horizon, typically prioritizing long-term infrastructure and manufacturing projects over quick exits. External advisors are used for specialized asset classes like energy transition and renewable energy storage.
How does East Penn's family office source proprietary deal flow?
The firm generates proprietary opportunities through its deep vertical integration in battery manufacturing, recycling, and logistics. Suppliers, joint venture partners, and customers often present co-investment and expansion opportunities in battery technology, industrial automation, and renewable energy storage. The firm's 100+ country export network also surfaces international growth opportunities.
Is East Penn Manufacturing structured as a single family office or does it operate more like an industrial holding company?
It functions as a hybrid single-family office and industrial holding company. The core operating business remains East Penn Manufacturing Co., but the family office manages separate investment vehicles for real estate, infrastructure, and renewable energy projects. Profits from the battery business are reinvested into capital projects and adjacent ventures rather than distributed to external investors.
Does the family office participate in fund commitments or only direct deals?
The family office focuses primarily on direct investments in its own manufacturing and logistics operations. It has been known to participate in fund commitments through limited partner stakes in infrastructure and energy-transition funds, but these are secondary to self-sourced industrial projects. Deal flow is largely organic, arising from the family's supply chain and customer network.
What investment stages does the family office typically target?
The firm targets later-stage and growth-stage investments in industrial manufacturing, battery technology, and renewable energy storage. It avoids early-stage venture capital, preferring to deploy capital at scales that leverage its operational infrastructure. Capital commitments often exceed $100 million per project, aligned with the family's ability to control supply chains.
Which sectors does the family office explicitly avoid?
Publicly, the firm avoids sectors outside its industrial and energy-storage core, including software, financial services, healthcare, and consumer goods. Its focus remains on tangible assets: battery manufacturing, recycling, logistics, and renewable energy infrastructure. The family office does not engage in hedge fund or private equity fund-of-funds strategies.
Where does the underlying wealth come from?
The wealth originates from East Penn Manufacturing Company, founded in 1946 by DeLight E. Romesburg Sr. The company has grown to become one of the largest single-site lead-acid battery producers globally, with annual revenues estimated in the billions. The Romesburg family retains 100% private ownership, with wealth derived from operational profits and real estate holdings.
