“This quarter reaffirmed the resilience of our diversified business,” said Larry Wu, Founder and Chief Executive Officer. “The return to top-line growth in Noble House reflects the impact of focused optimization, and our planned acquisition of New Classic advances our vision of a truly channel-agnostic B2B marketplace that connects suppliers and retailers with greater reach and efficiency. Through disciplined execution and a robust, debt-free balance sheet that supports our growth initiatives, we continued to scale in a difficult environment and strengthen the foundation for long-term value creation. The macro environment is beyond our control, but how we execute and adapt is not. Resilience is what keeps us moving forward.”

“Our disciplined execution generated $78 million in operating cash flow this quarter, providing the fuel to execute our long-term capital allocation strategy with precision,” said Erica Wei, Chief Financial Officer. “This allows us to consistently return capital to shareholders through buybacks — a highly effective tool for enhancing earnings per share — while simultaneously investing in strategic acquisitions to secure our future growth pipeline.”

On October 24, 2025, GigaCloud announced that it has entered into a binding term sheet to acquire 100% of New Classic Home Furnishings, Inc. (“New Classic”) for $18 million in cash. At closing, New Classic will become a wholly owned subsidiary of GigaCloud, further expanding the Company’s channel-agnostic B2B marketplace and enhancing its domestic distribution capabilities.
