The Chinese capital market and the express delivery logistics sector witnessed a significant regulatory event on August 4, 2026. The State Post Bureau officially announced the initiation of an investigation into Sto Express Co.,Ltd. (hereafter referred to as STO Express), specifically targeting its wholly-owned core operational subsidiary, STO Express Co., Ltd. The announcement pinpointed recent operational pain points for STO Express, citing multiple production safety incidents at companies operating under the "STO Express" trademark, name, and waybills this year, along with repeatedly identified safety hazards at worksites. Regulators concluded that the brand headquarters had severely neglected its safety production management responsibilities for these related enterprises, failing to fulfill the unified management obligations for network-wide security as required by regulations.
On the evening the investigation was announced, STO Express urgently convened the 22nd meeting of its sixth board of directors. At an unprecedented speed, it approved the termination of its plan to issue convertible bonds to unspecified objects and decided to fully withdraw the relevant application documents from the Shenzhen Stock Exchange. Notably, this refinancing project, with a total amount not exceeding 30 billion yuan, had been meticulously planned for months and had undergone multiple rounds of regulatory inquiries. It was originally scheduled to be formally reviewed by the SZSE's listing committee tomorrow, August 7, 2026. Such a hasty withdrawal at the final stage often signifies a deep-seated crisis in the quality of underlying assets and hidden compliance and information disclosure risks under the comprehensive registration-based IPO system.
Why were 52 penalties against STO Express over three years classified as incidental?
According to data disclosed in the inquiry response documents, during the reporting period from 2023 to 2025, STO Express and its significant subsidiaries faced a total of 52 administrative penalties, each involving a single fine of 10,000 yuan or more, amounting to a cumulative total of 3.045 million yuan. An analysis of the composition of these penalties reveals that they are not isolated management flaws but exhibit a highly concentrated pattern characteristic of industry-specific high risks. In response to the SZSE's pointed inquiry about whether the relevant internal control and management systems were sound and effectively implemented, whether they could prevent related legal and compliance risks, and whether they constituted an obstacle to the issuance, the verification opinions submitted to the exchange by Zhou Jiang and Bai Rixing of CITIC Securities appeared to employ a logic that deliberately fragmented the facts and isolated the amount of individual fines. Their argument focused heavily on the "individual fines being concentrated in the 10,000 to 50,000 yuan range, which is considered a small amount," leading to the conclusion that "the relevant companies have paid the fines and completed rectifications, so the violations are not material and do not constitute an obstacle to the issuance." The question is whether this reasoning is logically sound and whether it violates the fundamental audit and compliance assessment principles of "substance over form" and the progression from "quantitative to qualitative change." Did Zhou Jiang and Bai Rixing of CITIC Securities violate the strict requirements of the "Standards for the Due Diligence Work of Sponsors," which mandate that "sponsors must comprehensively verify the completeness, reasonableness, and effectiveness of the issuer's internal control system"?
As seasoned sponsor representatives with extensive experience in refinancing and restructuring projects (public records show Zhou Jiang worked on major projects for China Eastern Airlines, China Merchants Energy Shipping, and SF Holding's restructuring; Bai Rixing worked on projects for Air China and Hainan Airlines), they should possess high professional sensitivity. Faced with 27 consecutive safety production penalties over three years, these two representatives should have keenly recognized that this was not a series of coincidental isolated events. Instead, it is a systemic symptom of STO Express' franchise network, characterized by a long-standing "management by punishment" approach, weak headquarters control over grassroots outlets, and severe underinvestment in safety production. These safety hazards have already led to irreversible tragic consequences. Public records and official reports show that in 2024, the Market Supervision Department of the State Post Bureau conducted an administrative interview with STO Express following a fatal accident at its Heilongjiang sorting center, where a collapsing conveyor killed one employee, pointing out improper equipment installation and lack of safety management. Earlier, in 2021, a fatal machinery accident also occurred at STO Express' Tianjin branch. Faced with such serious casualties and high-frequency administrative penalties, Zhou Jiang and Bai Rixing, in constructing their working papers and response logic, clearly avoided a substantive on-site verification of "headquarters' penetrative safety management capabilities." They failed to establish a logical correlation between the frequent fatal accidents at grassroots outlets and the headquarters' compliance monitoring mechanism. Instead, they mechanically and superficially collected proof of paid fines and standard-format certifications from local authorities stating the violations were "not material or major," using these to handle regulatory inquiries. When the State Post Bureau initiated the formal investigation into Sto Express Co.,Ltd. on August 4, 2026, citing "lack of safety production management, failure to implement unified security management as required," did the credit endorsement of "sound internal control system effectively implemented" explicitly stated in the "Sponsorship Letter for Securities Issuance" by Zhou Jiang and Bai Rixing of CITIC Securities collapse, indicating a failure to exercise due diligence?
Why did a newly established company with a million-yuan capital win multi-billion yuan contracts from STO Express? What financial abyss lies behind prioritizing small suppliers over large, established ones?
According to disclosures in the audit inquiry response documents, the company You Liansheng was established on October 26, 2023, with a registered capital of merely 1 million yuan. Its equity structure consists of two natural persons: Sun Wenyou holds 51% and Zhang Zhe holds 49%, with Sun Wenyou also serving as the legal representative. However, this micro-enterprise, newly established with no historical track record or deep industry experience, skyrocketed to become STO Express' second-largest network-wide supplier in 2024, the year after its founding. By 2025, it became the undisputed largest supplier. Defying common business sense is the transaction volume between the two parties. According to disclosed data, the procurement of logistics auxiliary services (mainly business outsourcing and the core "direct dispatch fee" business in the express network) by STO Express from You Liansheng and its affiliates amounted to a staggering 47.73 billion yuan (specifically disclosed as 47,731.78 million yuan) in 2024 and 53.32 billion yuan (specifically disclosed as 53,320.785 million yuan) in 2025. In response to the SZSE's inquiries in the follow-up letter about "the reasons and rationality for You Liansheng becoming the issuer's supplier shortly after its establishment" and "whether it is a related party based on equity, and whether the transaction pricing is fair," did the explanations given by STO Express and Zhou Jiang and Bai Rixing of CITIC Securities defy basic business logic?
The response stated that You Liansheng could handle such a massive business scale because it relied on "the human resources management experience endowment of its partner, Doumi Youpin Technology Development Co., Ltd. (Doumi Group, a human resources service platform incubated from 58.com)." It claimed that by leveraging this, You Liansheng could offer competitive service rates (calculated to be around 5% weighted average annual service rate for 2025) while handling large volumes, meeting the issuer's goal of increasing supply chain concentration. Does this explanation reveal discrepancies in the verification groundwork for You Liansheng by Zhou Jiang and Bai Rixing of CITIC Securities? The fundamental flaw in the business logic is: if Doumi Group truly possessed the strong capability and experience to handle logistics auxiliary and dispatch fee distribution business worth over 50 billion yuan annually, why wouldn't STO Express, a listed company worth tens of billions, simply sign a long-term strategic cooperation agreement directly with the powerful Doumi Group? Why was it necessary to channel huge sums of money through You Liansheng, a "shell-like" intermediary company just established by two individuals, Sun Wenyou and Zhang Zhe, with a registered capital of only 1 million yuan? Does this not violate the principles of fund security and compliance transparency that large listed companies must adhere to in their supply chain management? The "substance over form" verification of related parties completely failed. In determining whether You Liansheng had a hidden related-party relationship with the issuer's actual controllers Chen Dejun, Chen Xiaoying, and their affiliates, the due diligence methods of sponsor representatives Zhou Jiang and Bai Rixing of CITIC Securities appeared superficial. According to the response documents, the sponsor's primary verification basis was simply "obtaining a statement from You Liansheng confirming no related-party relationship exists." Is this not a perfunctory "passive confirmation-based verification" in audit practice? For a supplier established just before a major transaction involving tens of billions annually, a qualified and mandatory due diligence procedure should include: in-depth penetration investigation of the immediate family members and past career trajectories of You Liansheng's actual controllers, Sun Wenyou and Zhang Zhe, to rule out the possibility of them holding shares on behalf of STO Express insiders. More critically, a thorough penetrative tracking audit of You Liansheng's bank account flows is necessary to trace the ultimate destination of the tens of billions of yuan flowing into its accounts annually after deducting the so-called 5% "service fee." Are these funds genuinely and fully distributed to the grassroots couriers? Is there a possibility that the funds flow back into accounts controlled by STO Express' actual controllers, Chen Dejun and Chen Xiaoying, through complex hidden channels, used to inflate business volume revenue or for interest transfer? The "direct dispatch fee" model masks compliance and tax risks. You Liansheng's core business includes "direct dispatch fee." In the deep waters of the franchise express industry, direct dispatch fees usually mean that the headquarters bypasses the franchisee and distributes the dispatch fees directly to the bottom-level couriers' accounts through third-party flexible employment or payment platforms. Channeling tens of billions of dispatch fees through a third-party micro-platform like You Liansheng involves extremely complex issues regarding labor relationship definition, compliance with personal income tax withholding and remittance, and the significant evasion of social insurance obligations. By simply noting that You Liansheng's 5% service fee rate is numerically close to other suppliers' rates (4.50%-7.00%), did Zhou Jiang and Bai Rixing of CITIC Securities lightly conclude that "the pricing is fair, has a reasonable business background, and does not harm the listed company's interests," lacking a multi-dimensional substantive verification of the authenticity of the underlying service delivery and tax compliance legality of this massive transaction?
Did the investigation into STO Express puncture the illusion of franchise compliance? Why does headquarters' cost-shifting to grassroots networks remain an effective strategy? Amidst safety red line failures, did Zhou Jiang and Bai Rixing of CITIC Securities truly fulfill their duties?
STO Express, as one of the earliest and most representative franchise-based express delivery leaders in China, saw its actual controllers Chen Dejun and Chen Xiaoying reap the benefits of the asset-light franchise model for years, enjoying rapid scale expansion and high capital market premiums. However, as China's express industry enters the deep waters of stock competition and high-quality development, the past extensive or even exploitative management model—relying on "headquarters collecting brand franchise fees and waybill fees, squeezing grassroots profits, and shifting blame for problems to franchisees"—has reached the end of its legal and compliance framework. In the investigation notice on August 4, 2026, the State Post Bureau precisely identified the problem with STO Express' model: "Companies operating express business using the 'STO Express' trademark, name, and waybills have experienced multiple production safety incidents... STO Express Co., Ltd. has failed in its safety production management responsibilities for these related enterprises, not implementing unified security management as required." This industry-landmark investigation, with its solid legal basis in the "Interim Regulations on Express Delivery" and the "Measures for the Supervision and Administration of Postal Industry Safety Production," signifies a fundamental shift in the national industry regulatory logic: from merely imposing single-point penalties on the violating grassroots outlets after an accident to tracing responsibility upward to the brand headquarters based on the principle of "brand authorization and substantive control."
In the prospectus and subsequent inquiry response documents submitted to the SZSE, did the issuer's actual controllers Chen Dejun and Chen Xiaoying, in collaboration with sponsor CITIC Securities and Beijing King & Wood Mallesons Law Firm, employ sophisticated, evasive, or ambiguous information disclosure tactics? First, in the risk warning section of the issuance documents, the disclosure by Zhou Jiang and Bai Rixing of CITIC Securities regarding the inherent risks of the franchise model was limited to procedural, template-like clichés, such as "if franchisees manage poorly, it may adversely affect the company's brand image." They deliberately avoided mentioning that under the new industry regulatory framework, STO Express headquarters bears an inescapable "joint and several" and "unified" statutory safety guarantee and labor compliance obligation for the tens of thousands of franchise network employees and the vast nationwide operating sites. The Chen siblings, as actual controllers, have long used complex franchise agreements to externalize the costs of network infrastructure investment below the transit centers, safety hazard rectification, and employment risks, shifting them to grassroots franchisees to maintain a rosy profit statement for the listed headquarters. However, this implicit cost-shifting mechanism was bound to collapse under the intensified penetrative regulation, and rectification compliance would inevitably lead to a significant exponential increase in the headquarters' management costs and safety investment. Second, when responding to the SZSE's audit inquiry regarding "unconcluded major litigation and arbitration and its latest progress, and whether the internal control management system is sound and effectively implemented," the issuer and Zhou Jiang and Bai Rixing of CITIC Securities continued to assert that "even if the judgment in relevant cases is unfavorable to the company, it will not have a material adverse impact on the company's production and operation, financial condition, or the implementation of the fundraising project." Does this superficial legal explanation mask the underlying business risks? In fact, the frequent occurrence of safety production accidents (especially fatal ones) is not just a civil issue of compensating for economic losses of hundreds of thousands of yuan; it involves the legal validity of STO Express' vital "Express Business Operation Permit." The State Post Bureau had already conducted administrative interviews with STO Express after the accidents occurred, but the headquarters apparently ignored them, failing to learn lessons from the root cause. Instead, in the refinancing application documents, they continued to use glossing terms like "currently, the company's various business operations are stable," "the entire network's production and operation remain normal," and "various services are proceeding smoothly and orderly" to present to the SZSE and public investors. When the regulatory announcement on August 4 directly initiated an investigation into the wholly-owned core subsidiary, according to the rigid compliance requirements for refinancing, Zhou Jiang and Bai Rixing of CITIC Securities, before the final investigation and penalty conclusions were reached, likely lost the legal basis to issue an unqualified compliance verification opinion, effectively physically closing the refinancing channel. Did this puncture the long-held illusion of "compliant operations and sound internal controls" at STO Express, rendering the commitments in the "Sponsorship Letter for Securities Issuance" and "Sponsorship Letter for Listing" issued by Zhou Jiang and Bai Rixing of CITIC Securities worthless? In the statutory declarations of the sponsorship letter, the sponsor explicitly vowed to "act in good faith, be diligent and responsible... guarantee the authenticity, accuracy, and completeness of the documents issued" and "if the documents produced contain false records, misleading statements, or material omissions causing losses to investors, we will compensate investors according to law." Faced with the long-standing management chaos and deeply entrenched safety hazards across the entire franchise network, did Zhou Jiang and Bai Rixing of CITIC Securities fail to leave their offices to expose the decay at the network's bottom through substantive due diligence methods like on-site visits, surprise inspections, and undercover checks? Instead, they tried to pass the review right up to the eve of the hearing, demonstrating a disregard for core regulatory norms such as the "Company Law," "Securities Law," and the "Administrative Measures for the Registration-Based Issuance of Securities by Listed Companies"?
