Ultra Clean Holdings sets up $400 million at-the-market share sale program
Ultra Clean Holdings entered a sales agreement on August 14, 2026, allowing it to sell up to $400 million of common stock through an at-the-market offering using four sales agents. The company is not obligated to sell any shares and may suspend sales at any time, so the program's actual size and timing are at its discretion. Because new shares would add to the outstanding count, existing shareholders could see their ownership diluted if sales occur.
Key points
- Maximum offering size is $400 million of common stock, with sales made at the company's discretion.
- Sales Agents are UBS Securities LLC, Barclays Capital Inc., Craig-Hallum Capital Group LLC and Oppenheimer & Co. Inc.
- Agents may receive commissions of up to 3.0% of gross offering proceeds.
- Shares are issued under a Form S-3 shelf registration filed March 25, 2024 (Registration No. 333-278195).
