U.S. Transit Agencies Rebuild Bus Fleets Amid Funding and Procurement Uncertainty

U.S. transit agencies are rebuilding bus markets amid funding uncertainty, changing procurement models, and a shifting manufacturing landscape. At APTA Expo 2026 in Chicago, manufacturers presented varied approaches to fleet renewal, including battery-electric, compressed natural gas (CNG), and hybrid buses. The discussion reflects a practical challenge for public operators: vehicle choices are linked to infrastructure, operating plans, utility capacity, workforce readiness, and the timing and predictability of available funding. Agencies therefore cannot assume a single technology or transition schedule will fit every fleet.

Mike Hynes, Deputy Director, Transit at Catalyst Mobility, discussed these issues in an interview with Sustainable Bus. He emphasized that transitions to advanced technologies take time and “it’s not a straight line.” That observation is relevant to procurement planning: agencies may need staged acquisitions, flexible specifications, and infrastructure plans that can accommodate different vehicles as operational needs and funding evolve. Battery-electric buses can require coordinated charging deployment and utility work, while CNG and hybrid options present different fleet, fueling, and operational considerations. The source does not identify specific solicitations or contract awards, but it highlights areas where agencies and their contractors may need planning and delivery support.

The interview also points to procurement approaches that can help agencies manage cost, complexity, and uncertainty. Joint procurement and state contracts may provide pathways for purchasing buses, while shared-use charging infrastructure could help avoid duplicative investment where agencies can coordinate. Contractors may find roles in charging deployment, utility coordination, technical support, and workforce development. These opportunities depend on local fleet choices and funding conditions, so vendors should avoid treating electrification as a uniform requirement across all agencies. Updating fleet electrification plans and connecting vehicle purchases with infrastructure and operating plans are central considerations.

Market access and institutional coordination are also changing. Manufacturers entering the U.S. transit market need to account for Buy America requirements, which affect how products are sourced and positioned for public-sector business. Catalyst Mobility is the new name adopted by CALSTART in September 2026, and the organization is set to combine with Forth at the beginning of 2027. Hynes described the combination as an opportunity to bring together policy and funding experience with technical expertise in zero-emission vehicle deployment, charging infrastructure, and fleet transitions. For GovCon firms, this points to a market where compliance, delivery capacity, infrastructure integration, and support for agencies’ varied transition paths can all influence procurement strategies.

• Funding uncertainty is affecting vehicle procurement, infrastructure investment, and transit agencies’ operating plans.
• APTA Expo 2026 in Chicago showcased battery-electric, CNG, and hybrid approaches to fleet renewal.
• Agencies should align vehicle specifications with charging or fueling needs, utility coordination, workforce requirements, and available funding.
• Joint procurement and state contracts are potential purchasing approaches for agencies seeking more flexible or coordinated buying.
• Contractors may pursue work in shared charging infrastructure, utility coordination, technical support, and workforce development.
• Manufacturers seeking U.S. transit business need to plan for Buy America requirements and related sourcing considerations.
• Fleet transition plans should be updated and tailored to each agency’s technology choices and funding constraints.
• CALSTART rebranded as Catalyst Mobility in September 2026 and plans to combine with Forth at the beginning of 2027.
• The planned Catalyst Mobility–Forth combination is intended to expand reach and bring together policy, funding, and technical expertise.
