HUZHOU CITY, China, August 13, 2025 (GLOBE NEWSWIRE) -- LZ Technology Holdings Limited (NASDAQ: LZMH) (“LZMH” or the “Company”), a leading provider of information technology and advertising services, today announced that all of its principal shareholders have entered into agreements with the Company to extend their lock-up restrictions until August 31, 2026. This extension follows the original 180-day lock-up period established in connection with the Company’s initial public offering completed in February 2025

The principal shareholders participating in the extension include LZ Digital Technology Holdings Co., Ltd, BJ Tojoy Shared Enterprise Consulting Ltd, Vanshion Investment Group Limited, Youder Investment Group Limited and Kim Full Investment Company Limited. Collectively, these shareholders hold approximately 100% of the Company’s issued and outstanding Class A ordinary shares and 96.19% of the Company’s issued and outstanding Class B ordinary shares. Pursuant to the terms of the lock-up agreements, these shareholders are prohibited from, directly or indirectly, selling, transferring or otherwise disposing of the Company’s ordinary shares, or any securities exercisable for, exchangeable, or convertible into ordinary shares, without the Company’s prior written consent, until August 31, 2026.

This lock-up extension reflects the continued long-term confidence and support of the Company’s founder and core investor base as LZMH executes on its strategic initiatives and pursues further growth across key markets.

“We are grateful to our early investors for their ongoing support and shared commitment to the long-term success of LZMH,” said Runzhe Zhang, CEO of LZMH. “This extension provides a strong foundation as we continue to expand our operations and deliver value to shareholders.”
