Princeton Technology Corp. regularly discloses relevant information on the Market Observation Post System (MOPS). In addition, a dedicated Stakeholder Section has been established on the corporate website to serve as a primary communication channel for stakeholders to address material issues with the Company. To maintain active engagement, PTC also holds Annual General Meetings (AGM) and Earnings Calls (Investor Conferences) every year to communicate directly with all stakeholders.

PTC has always been committed to sound business management, abides by government laws and regulations, upholds integrity and openness, adheres to quality, encourages innovation and focuses on efficiency as management and operating principles, and formulates various internal measures to ensure honest management and compliance with laws. The company's directors and managers operate with integrity as their main principle. If any decision or transaction involves a conflict of interest, based on the principle of avoidance of interests, directors and managers are not allowed to participate in voting. PTC will continue to formulate and improve regulations to truly implement corporate governance policies. It is expected to formulate an integrity management policy and pass it by the board of directors before the end of 2024.

PTC’s internal audit reviews the company's internal operations and subsidiary supervision and management according to the annual audit plan, and reports to the audit committee and the board of directors every quarter to ensure the continuous and effective implementation of the internal control system and as a basis for review and correction of the internal control system. If there are changes in domestic and foreign regulations or other situations where legal advice is required, the company not only has an in-house legal office that can assist in assessing legal risks and provide consultation, but also has long-term cooperation with Jones Day International Law Firm to seek various suggestions from it. In 2025, the Company did not have any violations of Article 36 of the Securities and Exchange Act and relevant regulations that should be disclosed to public information observatories or major violations of regulations that attracted public opinion or industry attention.

PTC fulfills corporate social responsibilities, pursues sustainable operations and profits under the principle of integrity, and pays attention to various issues such as environment, society and corporate governance. We hope that through appropriate communication with stakeholders, we can understand the reasonable expectations and needs of stakeholders, as well as the important corporate social responsibility issues of concern to them, and incorporate them into the basis for formulating the company's future management policies and operating activities.

There is a "Stakeholder Area" on the company's official website. Anyone who has concerns or suggestions about the company's operations or business practices can raise them through this area. Different professionals are responsible for assisting according to different issues. If a complaint case occurs, the handler should report it to the company's supervisor. If the circumstances are serious, an investigation team must be formed to handle the case. When handling the complaint case, the investigation team should uphold the principles of fairness, objectivity, and professionalism and handle it prudently, and carefully protect the complainant from complaint and suffer adverse treatment. If it is deemed necessary after the investigation is completed, the Company will report it to the relevant competent authority or transfer it to the judicial authority for investigation.

To ensure all employees uphold business integrity and comply with relevant regulations, PTC periodically sends company-wide emails to promote code of conduct regarding social responsibility. Additionally, in accordance with occupational safety and health regulations, the company conducts unannounced combined earthquake and fire emergency drills to ensure disaster prevention and safety management. In 2025, the training coverage rate reached 100%.
