Recent news flow shows mixed reactions: losses at the Jiangxi Jinko subsidiary have typically seen negative price moves, while some financial result updates and routine corporate actions coincided with sharp gains, indicating occasional divergence between fundamentals and price.

Recent Company History

Over the last several months, JinkoSolar news has centered on subsidiary losses and routine governance. A Jan 21, 2026 6-K and related release outlined sizeable preliminary full-year 2025 net losses at Jiangxi Jinko, which coincided with a modest share price decline. Earlier, Q2/Q3 2025 results on Nov 17, 2025 showed strong revenue but ongoing net losses and nonetheless aligned with a double-digit gain. Routine AGM scheduling and results in late 2025 also saw notable price swings. Against this backdrop, today’s IEC 62443-2-4 cybersecurity certification fits into a narrative of strengthening the ESS business amid financial volatility at the subsidiary level.

vulnerability management technical

"maintains controlled vulnerability management and patching processes; and applies"

Vulnerability management is the ongoing process of finding, fixing and tracking weak spots in a company’s computer systems and software before attackers exploit them. It matters to investors because unchecked weaknesses can lead to costly breaches, fines, downtime and harm to customer trust — similar to routinely inspecting and repairing locks on a storefront to avoid break-ins and protect future revenue and reputation.

critical infrastructure technical

"required to protect critical infrastructure. This independent validation gives"

Critical infrastructure are the essential systems and facilities—such as power grids, water supply, telecommunications, transportation networks, financial systems and healthcare services—that society and the economy rely on to function. For investors, these assets matter because damage, outages or regulation affecting them can abruptly disrupt business operations, revenue and market value; conversely, their stable, mission-critical nature often attracts steady demand, government support or long-term contracts, reducing risk much like a solid foundation supports a house.

CAMPBELL, Calif., Feb. 4, 2026 /PRNewswire/ -- JinkoSolar Holding Co., Ltd. (the "Company"), JinkoSolar, a global leader in clean energy technology, today announced that its Jinko ESS North American business unit has received IEC 62443-2-4 certification from exida, a globally recognized authority in industrial cybersecurity and functional safety.

IEC 62443-2-4 is an internationally respected standard that defines best practices for secure development lifecycle (SDL) processes for service providers of industrial automation and control systems. Certification confirms that cybersecurity is not treated as a bolt-on feature but is embedded across system design, development, integration, testing, deployment, and lifecycle management. 

Unlike companies that retrofit cybersecurity in response to regulation or market pressure, Jinko ESS has championed a "secure by design" philosophy across its energy storage products, systems, and processes since the inception of its ESS business. Over time, Jinko ESS has doubled down on investment in cybersecurity governance, engineering, and controls, recognizing early that energy infrastructure demands the same rigor as critical industrial systems.

"Cybersecurity is not simply a department at Jinko ESS. It is a foundational design principle," said Jeff Juger, U.S. Managing Director of Jinko ESS. "From architecture decisions to supplier management to incident response planning, cybersecurity is ingrained into how we operate."

IEC 62443-2-4 certification validates that Jinko ESS operates a formal, audited secure development lifecycle; integrates threat modeling, risk assessment, and secure supply chain; maintains controlled vulnerability management and patching processes; and applies cybersecurity controls across 3Ps: people, process, and products. This independent assessment confirms that Jinko ESS's cybersecurity practices meet the rigorous standards of utilities, data centers, regulators, and sophisticated enterprise customers operating in high-risk environments.

"True security is found in the process, not just the product," added Michael Medoff, Director of Certification at exida. "By achieving IEC 62443-2-4 certification, Jinko ESS has proven they have the rigorous system Integration and Maintenance processes and governance required to protect critical infrastructure. This independent validation gives utilities and enterprise customers the confidence that security is ingrained in every step of their partner's service lifecycle."
