Gritt and MasTec partner to bring physical AI to solar construction sites. Gritt has announced a partnership with MasTec, one of North America's leading infrastructure builders, to deploy its AI-powered systems across MasTec Renewables projects and plans to explore applications in additional infrastructure sectors. Gritt develops intelligence for physical construction work and deploys it through robotic attachments to common construction equipment to help crews work more safely, efficiently and productively. Gritt is developing general-purpose construction intelligence designed to work across tasks, equipment configurations and job site conditions. Its AI learns physical tasks, including picking and placing, assembly and material transport, while craft employees guide and validate the work. Gritt systems have operated in conditions ranging from rain-soaked fields to deserts and snowy plains. Beyond performing physical work, the technology monitors job site activity to help inform planning and decision-making. Rob Turner, vice president of construction at MasTec Renewables, says: "Its craft workforce brings the skill and experience that make large-scale infrastructure possible. Its focus is on giving its people the tools to do that work safely and effectively. "We've evaluated Gritt systems on active construction sites, and we see an opportunity to pair our teams' expertise with technology that supports them in the field." The partnership follows successful field deployments and MasTec Renewables' extensive evaluation of Gritt's systems through the installation of megawatts of solar panels on active job sites. The companies will expand their work together through a pipeline of projects, initially focused on MasTec's growing utility-scale solar portfolio across multiple states. Puneet Puri, co-founder and CEO of Gritt, says: "MasTec knows what it takes to deliver critical infrastructure at tremendous scale. "Together, we are putting construction intelligence to work on construction sites, with the ambition to transform how quickly the world can build. Every deployment is an opportunity to make our systems more capable, and MasTec's craft expertise and project experience make it an ideal partner as we bring that vision into the field."

MasTec (NYSE: MTZ) has halted late-stage talks on a large acquisition to focus on buying back its own shares. Management called the deal potentially accretive but is directing capital to buybacks under its current allocation priorities. The company has a $250 million repurchase authorisation. It reported sales of $5.15 billion in the third quarter of 2026 and nine-month net income of $341.52 million. MasTec, which has a market cap of $12.6 billion, runs engineering and construction projects for communications, energy, and utility clients across the US and Canada. Its backlog stands at about $21.4 billion. Investors will watch whether 2026 GAAP diluted earnings per share land between $5.69 and $6.01, and whether buybacks are funded by operating cash flow.
