Brooks Automation Eyes IPO as PE Firms Rush to Public Markets

Brooks Automation, a robotics and automation software provider serving semiconductor manufacturers and life sciences companies, is exploring a potential initial public offering, according to sources familiar with the matter.

The company, which employs more than 2,000 people across 14 countries, is currently in preliminary discussions with financial advisers about a possible listing. Thomas H. Lee Partners, the private equity firm that acquired Brooks for $3 billion in a deal announced in 2021 and closed in 2022, owns the company. Neither Brooks Automation nor Thomas H. Lee Partners provided comment on the potential IPO, and sources cautioned that terms remain fluid and the deal could change or not materialize.

What Brooks Automation Sells

Brooks Automation builds precision robotics and software controls for handling delicate materials in controlled manufacturing environments. Its customer base includes major chipmakers and pharmaceutical companies that depend on its equipment for semiconductor fabrication facilities and biotech laboratories.

The current Brooks Automation represents the core automation technology business that remained after Thomas H. Lee Partners split off the life sciences division following its acquisition. That separated entity, renamed Azenta Inc., continues to trade on the Nasdaq. The streamlined Brooks now focuses exclusively on its robotics and software automation technologies for semiconductor manufacturing, life sciences, and industrial automation applications.

Why it matters

The potential Brooks listing reflects a broader pattern of private equity firms capitalizing on favorable market conditions to exit investments held for several years. Rising demand for automation in semiconductor fabs and biotech labs has positioned Brooks as a potentially attractive public company, even as PE firms face pressure to return capital to investors. The timing of these discussions coincides with the strongest IPO market in five years, creating a window for exits that may not remain open indefinitely.

Record Year for Public Offerings

Brooks would enter a robust IPO market if it proceeds. The U.S. IPO market raised $156.8 billion in 2026, the highest total since 2021, with private equity-backed companies driving much of that activity.

Recent examples illustrate the trend. Jersey Mike's Subs, backed by Blackstone, is seeking to raise up to $1.09 billion in an offering scheduled for next week. Reformation Inc., a sustainable women's clothing brand owned by Permira, may raise as much as $239 million. Despite operating in vastly different sectors, these companies follow the same private equity playbook: acquire, grow, and exit through public markets when conditions favor strong valuations.

The surge in PE-backed IPOs represents firms cashing out after holding portfolio companies through a multi-year growth period, often timed to coincide with bull market conditions that maximize returns. For investors, the wave of new offerings expands opportunities to access companies before they achieve widespread recognition, though it also increases the complexity of evaluating which listings merit attention.
