Group 1 - The core point of the news is that Deep Blue Ocean Technology Co., Ltd. has changed its IPO guidance status to "Acceptance of Guidance," aiming to list on the Sci-Tech Innovation Board after two years of guidance work [2][3] - Deep Blue was established in 2013 and focuses on the research, production, and sales of underwater intelligent equipment, covering both industrial and consumer segments [3] - The company has participated in significant national projects, including Arctic scientific research and emergency support for the Shenzhou spacecraft, showcasing its industrial-grade products like ROVs and AUVs [3] Group 2 - Deep Blue's consumer brand, Sublue, claims over 60% of the global market share in underwater propulsion devices, with 70% of its revenue coming from overseas markets [3] - The company has raised over 1.3 billion yuan in historical financing, attracting investments from over 30 institutions, but has a dispersed shareholding structure with the actual controller holding only 23.64% [3] - Analysts suggest that to sustain its high valuation, Deep Blue needs to move beyond a hardware sales model and create a "hardware-content-ecosystem" closed loop, emphasizing the importance of cost control and scalability in its IPO process [3] Group 3 - Deep Blue's IPO attempt represents a significant challenge in the underwater intelligent equipment sector, particularly in the context of the growing "blue economy" concept [3] - The company must find a balance between technological barriers, market expansion, and ecosystem construction to succeed in its IPO journey [3]

Core Viewpoint - The search for MH370, marking its 11th anniversary, is not just a governmental response but a calculated commercial experiment involving Ocean Infinity's advanced underwater technology and a $70 million "no find, no fee" clause [2][3]. Group 1: Search Methodology - The search has evolved from traditional grid methods to Bayesian search theory, which updates prior probabilities based on fragmented data, narrowing down the search area to a precise 15,000 square kilometers [3]. - Ocean Infinity's deployment of autonomous underwater vehicles (AUVs) not only aims to find the aircraft but also to create high-resolution seabed maps, which hold significant value in the context of submarine warfare and deep-sea resource exploration [3]. Group 2: Potential Outcomes and Implications - Finding the wreckage may not resolve the controversy but could initiate new legal and geopolitical challenges, especially if mechanical failure or crew manipulation is implicated [4][5]. - The search's intermittent nature reflects a balance of interests among stakeholders, as certainty could lead to significant financial and diplomatic repercussions for involved parties [5]. Group 3: Strategic Insights - The incident emphasizes the need for China to develop independent aviation safety protocols and capabilities, reducing reliance on Western companies for search operations [6]. - The tragedy of MH370 serves as a reminder that possessing core technologies and data sovereignty is crucial for ensuring safety in uncertain environments [6].
