Every day, thousands of skilled technicians test electrical systems, inspect cranes and pressure vessels, calibrate instruments, service aircraft, maintain fire and life safety systems, and keep water, power, and production flowing to hospitals, data centers, plants, and communities across America. This work is essential. It requires deep expertise, years of training, and companies that have earned the trust of their customers over decades. These companies deserve an owner who understands what they do, respects how they do it, and plans to be there for the long term. That is what Eterna was built to do.
The infrastructure that powers modern life requires constant testing, maintenance, inspection, and protection. Our companies are on the front lines of that work.
This work runs on expertise. Our companies employ technicians, engineers, and specialists whose knowledge takes years to develop and cannot be replaced.
When ownership changes, teams get disrupted, customer relationships fracture, and institutional knowledge walks out the door. We exist to prevent that.
We do not flip companies. We do not strip costs. We acquire businesses with the intention of holding them permanently and helping them grow on their own terms.
We focus on essential industrial services businesses that require deep technical expertise, hold the certifications their work demands, and deliver recurring, non-discretionary work. Our six categories represent the disciplines that keep critical infrastructure safe, reliable, and compliant.
Electrical testing and maintenance, power system engineering, substation automation and controls, critical power systems, safety and compliance, and apparatus repair and reconditioning. The backbone of every facility that cannot afford to go dark.
Aircraft line and base maintenance, component and accessory shops, avionics and instrument repair, landing gear and wheel and brake overhaul, and engine and airframe support. FAA-certificated work where downtime is measured in dollars per hour.
Nondestructive testing and in-service inspection, crane and lifting equipment inspection, elevator inspection, calibration and metrology, cleanroom and controlled environment certification, and cathodic protection and corrosion control. Independent verification that keeps assets certified and operators compliant.
Rotating equipment and turbine overhaul, precision alignment and field balancing, vibration analysis and condition monitoring, pressure vessel and relief valve repair, steam and compressed air systems, and bolted joint integrity. Keeping the machines that run the plant turning.
Sprinkler and alarm inspection, testing and maintenance, clean agent and special hazard suppression, fire pumps, fire and smoke dampers, medical gas verification, and emergency communications. Code-mandated work that protects people and buildings.
Backflow prevention testing, potable water storage inspection and cleaning, industrial water treatment and Legionella compliance, hydrant and valve programs, emissions monitoring, and underground storage tank compliance. Non-negotiable work that keeps water safe and permits intact.
Most acquirers in this space are private equity firms building portfolios to flip in three to five years. We are not. Eterna Companies is built on permanent capital with no fund lifecycle, no exit timeline, and no pressure to sell. We buy companies to own and grow them for decades.
No exit timeline. No fund lifecycle. No pressure to sell in three to five years. We are backed by leading long-duration investors who share our commitment to permanent ownership. When we acquire a company, it becomes part of Eterna for good. Your legacy is protected by capital that is built to last as long as your business.
Your brand, your team, your customer relationships, your way of doing business. We add resources and remove headaches. We do not add layers of management or centralize decisions that belong close to the customer.
As part of the Eterna family, operators who want to grow beyond their company have opportunities to take on new challenges, develop professionally, and contribute at a broader level. Growth is always optional, never forced.
Selling your business is personal. We keep the process honest, direct, and transparent. You will always know where you stand, what we are thinking, and what comes next.
We start with a straightforward conversation about your business, your goals, and whether Eterna might be the right fit. We do not ask for financials or a formal commitment until we know there is real, mutual interest.
If there is mutual interest, we learn about your company in detail. We review financials, visit your operations, and meet your team. We move quickly and communicate clearly throughout.
We present a clear, fair offer with no hidden conditions. Our terms are straightforward. We work with you to structure a deal that protects your team and reflects the value you have built.
After closing, your company joins the Eterna family. Your team stays. Your brand stays. Your way of operating stays. You gain access to resources, peer networks, and growth support without losing what makes your business work.
