Eplus3D IPO Withdrawn, CSRC Issues Regulatory Warnings to CITIC Securities Sponsors

China's Shanghai Stock Exchange has issued regulatory warning letters to Hangzhou Eplus3D Technology Co., Ltd., three of its senior executives, and two CITIC Securities sponsors, months after the company withdrew its IPO application. The exchange's on-site supervision found that Eplus3D had inadequate internal controls over R&D activities, including post-hoc compilation of timesheets and inconsistent project documentation. CITIC Securities sponsors Dong Chao and Yu Qidong were cited for failing to properly verify R&D expense allocation and for not adequately investigating close relationships between the company's shareholders, including potential undisclosed equity arrangements between Hangzhou Lansheng Management Consulting and Eplus3D's controlling shareholder, YongSheng Holding Group. Eplus3D, a national-level "Little Giant" specializing in industrial-grade metal and polymer AM equipment and services, had filed for a科创板 (STAR Market) IPO in June 2025, aiming to raise CNY 1.205 billion, before withdrawing in March 2026.

This case underscores the intensifying regulatory scrutiny on AM companies seeking public listings in China, particularly around R&D governance-a critical credibility marker for technology enterprises. Eplus3D, which competes with domestic peers like BLT (Bright Laser Technologies) and Farsoon Technologies in the metal PBF-LB space, now faces reputational damage that could slow its access to capital and customer qualification cycles. The CSRC's decision to pursue post-withdrawal enforcement signals that the era of "file and withdraw" to avoid penalties is over, raising the compliance bar for all AM firms pursuing IPOs. For the broader Chinese AM industry, which has seen rapid growth in printer sales and service revenue, this event highlights the tension between scaling production capacity and maintaining the rigorous documentation standards required for public markets and, by extension, for aerospace and medical qualification.

From a practical standpoint, Eplus3D must now rebuild its internal R&D documentation systems and governance processes before re-engaging with capital markets or major qualification-dependent customers. The company's near-term focus should be on demonstrating repeatable, auditable R&D workflows-a prerequisite for any AM firm targeting regulated verticals like aerospace or medical. For investors and industry observers, this case reinforces that AM companies in China are not exempt from the same governance standards applied to other industrial technology sectors, and that regulatory enforcement is becoming a material factor in competitive positioning.
