WEX Earnings Show AI’s Growing Role in B2B Payments

The competitive edge for the next generation of financial infrastructure companies is not visibility, but indispensability.

At a time when macroeconomic volatility continues to test business models, financial infrastructure players are focused on helping build resilience by embedding themselves deeper into the operational fabric of their customers.

That, at least, was the story WEX executives told investors on the company’s first quarter 2026 earnings call Thursday (April 23).

“We are firmly focused on executing our strategy to amplify our core, expand our reach, and accelerate innovation, and I am pleased to see the results. We continue to embed AI into our workstreams and product development processes to both accelerate operational efficiency and deliver smarter, more efficient payment workflows to our customers,” said Melissa Smith, WEX’s chair, CEO and president.

The “core” business—mobility payments, corporate payments and benefits administration—remain WEX’s foundation and were collectively responsible for a 5.8% year-over-year increase in revenue, which reached $673.8 million.

Mobility alone accounted for roughly half of annual revenue, reflecting WEX’s long-standing leadership in fleet and fuel payment systems. Meanwhile, benefits and corporate payments provide diversification into healthcare and B2B transaction ecosystems, each with distinct growth dynamics.

But if there was one theme that stood out from WEX’s earnings call, it was the operationalization of artificial intelligence (AI). The company reported dramatic improvements: claims reimbursement times reduced by 98%, product innovation velocity increased by 50%, and roughly 40% of coding now powered by AI.

Following its earnings report, WEX’s stock rose mid-single-digits on the news, as of PYMNTS reporting.

Growth in a Fragmented Payments Landscape

Over the past two years, WEX has reorganized its technology and product teams into leaner, more specialized units, explicitly designed to leverage AI across workflows. As executives stressed, AI is functioning as both a defensive and offensive asset. On the defensive side, it strengthens fraud detection and credit decisioning, which are critical capabilities in payments ecosystems where risk management directly impacts margins. On the offensive side, it enhances customer value through automation, insights and faster product iteration.

This framing reflects a larger industry shift. Payments are no longer a discrete function; they are becoming the connective tissue of enterprise operations. And as payments become the connective tissue, control is becoming a key factor in C-suite decisioning around the platforms they rely on. As a result, WEX’s messaging and its executive commentary on Thursday’s call consistently emphasized control: control over spending, visibility into cash flows and protection against fraud.

Ultimately, WEX’s long-term advantage may not lie in payments processing alone, but in the data generated by those transactions. Embedded within customer workflows, the platform captures granular insights into spending behavior, cash flow patterns, and operational inefficiencies.

The report, “Embedding Security: Designing Fraud Risk Out of Business Transactions,” by PYMNTS Intelligence and WEX, separately examined how embedded payments, financial services woven directly into business software platforms, are reshaping both transaction efficiency and fraud exposure.

By transforming this data into actionable intelligence through analytics, automation and AI, WEX’s executives are betting the company can move up the value chain to become not just a processor of transactions, but a provider of decision-making tools.

The Ongoing Transformation of Enterprise Payments

WEX’s first-quarter results do not represent a breakout moment. They are, instead, evidence of something more enduring: a methodical transformation of a payments company into a technology-driven infrastructure platform.

In the first quarter, the company processed total volume of $58.1 billion, up 7.5% year over year. Each operational segment contributed to growth, albeit in different ways. The benefits segment, for instance, saw revenue increase by 8.5%, supported by growth in SaaS accounts and custodial assets. Corporate payments expanded 9.3%, driven by increased transaction volume and enterprise adoption. Mobility, while more mature, still delivered steady gains.

Still, no payments company operates in a vacuum, and WEX is particularly exposed to macro variables such as fuel prices and interest rates. The company’s own guidance illustrates this sensitivity: a $0.10 change in fuel prices can shift net revenue by approximately $20 million, while a 100-basis-point change in interest rates can impact revenue by roughly $30 million.
