The Supreme Court's recent curb on emergency tariff powers gives global exporters a clearer rulebook, and that shift can matter a lot for your portfolio. With less risk of sudden, sweeping trade moves, large U.S. multinationals that sell heavily into markets like the U.K., Canada, Australia, and New Zealand may find their planning and pricing a bit easier. This article looks at three stocks from a U.S. Multinational Exporters screener that are closely exposed to this trade policy backdrop and explains how this ruling could be a meaningful factor to watch when deciding whether to invest or stay on the sidelines.

SOLV Energy (MWH)

Overview: SOLV Energy is a U.S. based power infrastructure company that designs, builds, and maintains large scale solar and battery storage projects, as well as related transmission and distribution assets, for developers, independent power producers, and utilities.

Operations: SOLV Energy generates approximately US$2.8b in revenue from heavy construction activities in the United States.

Market Cap: US$5.8b

Investors looking at SOLV Energy are getting exposure to a utility scale solar and storage contractor that sits at the center of major U.S. renewables build outs, while also benefiting from a clearer global trade rulebook that can help long term project planning. The stock screens as undervalued against analyst fair value estimates, with a P/E below U.S. construction peers and strong recent earnings growth, although revenue growth expectations trail the broader market. There are governance and funding questions to weigh, including a young board, reliance on external borrowing and a recent US$540m equity raise alongside a recent quarterly loss. That mix of rapid growth, index inclusion and higher risk capital structure is exactly why SOLV Energy deserves a closer look for exporters in this new tariff regime.

Rapid growth, index inclusion and an apparently cheap P/E raise big questions about what the market might be missing on SOLV Energy, and the analysis report for SOLV Energy hints at one factor that could flip the story.

Diebold Nixdorf (DBD)

Overview: Diebold Nixdorf is a global provider of banking and retail technology that supplies ATMs, cash recyclers, teller systems, and self checkout and point of sale platforms, along with software and services that help financial institutions and retailers automate how people withdraw cash, pay, and shop.

Operations: Diebold Nixdorf generates about US$2.8b from its Banking segment and US$1.1b from Retail, making banking automation its largest revenue driver by a wide margin.

Market Cap: US$3.0b

Diebold Nixdorf gives you direct exposure to the global automation of branches and checkout lanes, with banks and retailers leaning on its hardware, software, and managed services to manage costs and keep cash moving efficiently. The stock is described as attractively valued relative to some peers, with analysts expecting earnings growth to outpace revenue as higher margin service and software recur more steadily. At the same time, high debt, a recent US$98.3m one off loss, and a relatively new management team highlight execution risk, especially as digital only banking and cashless payments affect demand for legacy hardware. With the Supreme Court’s tariff ruling reducing the risk of sudden import shocks for a company that operates in more than 100 countries, the tariff reset could be important for margins and for confidence in its global rollout.

Earnings that may be accelerating faster than revenue, a global footprint in more than 100 countries, and fresh leadership make Diebold Nixdorf harder to read at a glance. The 3 key rewards and 2 important warning signs could reveal what that US$98.3m loss is really masking

Flex (FLEX)

Overview: Flex is a global manufacturing and supply chain partner that designs and builds electronics and hardware for data centers, communications, consumer devices, cars, healthcare equipment, industrial systems, and power infrastructure across the Americas, Asia, and Europe.

Operations: Flex generates about US$11.1b from Integrated Technology Solutions, US$10.2b from Regulated Manufacturing Solutions, and US$6.6b from Cloud and Power Infrastructure, supported by large production hubs in Mexico, the U.S., China, and other key manufacturing regions.

Market Cap: US$43.7b

Flex stands out in this U.S. Multinational Exporters screener because it sits at the heart of AI data centers, power infrastructure, and high value manufacturing at a time when trade rules are becoming more predictable after the Supreme Court tariff ruling. A sizeable global footprint, with Mexico as a major revenue center and contracts that often pass tariffs through to customers, means more stable cross border operations can matter directly for margins and planning. At the same time, thin 3.2% net margins, heavy reliance on external borrowing, insider selling, and big customer concentration leave little room for error if growth expectations or AI hardware demand change. The upcoming spin off of its power and cloud businesses, S&P 500 inclusion, and AI-focused capacity build out highlight how potential upside and execution risks for Flex can be closely connected.

Flex’s AI hardware push, thin 3.2% net margins, and upcoming spin off suggest the real story could be how growth and risk are interacting right now, and the analyst forecasts for Flex may show where that balance quietly shifts
