Average revenue per firm rises about 30% as integrators broaden skills in data, cybersecurity, and robotics.
WTWH Media—publisher of Control Engineering, Plant Engineering, and the Global System Integrator Report—is proud to present the 2026 System Integrator Giants ranking. Each June, we open submissions and invite system integrators to voluntarily share self-reported revenue from system integration (SI) activities. The resulting list offers a data-driven snapshot of the firms powering automation projects across industries, while reflecting the market forces that shape year-to-year results.

This year’s list again features 75 companies, matching the total from 2025. However, not all of last year’s System Integrator Giants returned to participate in 2026, and several new firms joined the ranking. The group collectively reported $4.67 billion in system integration revenue, a gain of roughly 18% over the prior year. Average revenue per ranked firm rose about 30%, signaling that growth extended beyond only the largest players. Among companies appearing in both years, roughly three-quarters reported higher SI revenue—a sign of continued demand for automation in manufacturing and process industries as organizations seek throughput, quality, and workforce leverage.
Not all gains were organic. Several firms reflected acquisition-driven changes, which can materially reset revenue baselines. Others noted corrections from prior reporting inconsistencies as teams refined how they attribute revenue to core integration work versus adjacent services. Beyond firm-level changes, macroeconomics played a role: contributors cited tariffs and pricing pressure, equipment and material cost inflation, and labor cost escalation as factors that shaped project pipelines, quoting, and delivery.
When asked about the biggest challenges of the past year, participants highlighted:
- The economy’s impact on the automation integrator market (27%)
- Identifying new prospective clients (13%)
- Staffing: quality of young engineers (13%)
- Rising costs of materials and equipment (11%)
- Rising labor costs (8%)
These responses reinforce what we hear across WTWH’s engineering communities: integrators remain uniquely positioned to blend operational technology domain expertise with modern automation, controls, and data practices, yet hiring and upskilling remain persistent hurdles. Many firms continue to broaden capabilities in areas such as cybersecurity, edge and cloud connectivity, data analytics, and robotics—often in close collaboration with OEMs and end users to standardize architectures and accelerate deployment.
As always, we caution readers that year-to-year revenue movement can reflect acquisitions, methodology improvements, or timing effects, not just organic growth or contraction. Our aim with the System Integrator Giants program is to provide credible benchmarking while recognizing the diversity of services SI firms deliver—from greenfield design and commissioning to modernization, migration, and lifecycle support.
We invite you to explore the full ranking. Congratulations to this year’s System Integrator Giants for their continued leadership in advancing safe, resilient, and data-ready manufacturing.
The data for the System Integrator Giants program is voluntarily provided by participating companies between June and September each year. Companies submit information on total gross revenue and total system integration revenue for their most recently completed fiscal year. Participation varies from year to year.
