Newmark Group Inc. (NASDAQ: NMRK) has hired Philip O'Bannon as Senior Managing Director to lead its Infrastructure Capital Markets business, the company announced.

O'Bannon brings more than 20 years of experience in investment banking and engineering to the role. He will focus on expanding Newmark's advisory and capital raising capabilities across infrastructure sectors including data centers, power and utilities, and energy transition projects.

The new hire will report to Andrew Warin, Head of Strategic Advisory, and collaborate with Newmark's Debt & Structured Finance and Data Center Capital Markets teams.

O'Bannon joins from Citigroup, where he spent seven years in the Power & Utilities Investment Banking group. During his tenure there, he advised clients on more than $50 billion of mergers and acquisitions, debt and equity capital markets transactions across energy and infrastructure sectors.

Before his investment banking career, O'Bannon worked at Lockheed Martin leading mechanical engineering efforts for submarine defense systems.

The Global Infrastructure Hub estimates global infrastructure investment needs will reach $94 trillion through 2040, driven by demand for data centers, energy transition assets, and digital and transportation infrastructure.

"As we have worked on an increasing number of infrastructure-oriented mandates, we recognized a need to deepen our capabilities across the sector," said Jordan Roeschlaub, Co-President of Global Debt & Structured Finance.

For the twelve months ended December 31, 2025, Newmark generated revenues of nearly $3.3 billion. The company operates from approximately 175 offices with over 9,300 professionals across four continents as of December 31, 2025.
