March 27, 2026 T O : All PESONet Participating Institutions R E : DOWNTIME ADVISORY – Scheduled PESONet Database Maintenance on April 2, 2026 1. Please be advised that PCHC will conduct database maintenance activities for PESONet to ensure continued performance stability and reliability. 2. The scheduled maintenance window is as follows: Date : April 02, 2026 (Holy Thursday) Time : 9:00 AM – 12:00 Noon Duration : Approximately 3 hours 3. During this period, PESONet services will be temporarily unavailable . All participating institutions are advised to make the necessary preparations in their respective systems and operations to accommodate this scheduled downtime. 4. PCHC appreciates your continued support and cooperation as we undertake these activities to further enhance system stability and service quality. 5. Please be guided accordingly.

March 23, 2026 T O : All PESONet Participating Institutions R E : API Security Implementation In PESONET 1. As part of PCHC’s continuing efforts to enhance system security, please be advised that an API security solution will be implemented to strengthen the management and monitoring of all API traffic within PESONet. 2. The implementation is expected to be transparent to all participants. However, participating institutions are advised that a new server certificate from AWS will be presented during the TLS handshake process. Accordingly, banks must ensure that their SSL/TLS libraries, middleware, and runtime environments (e.g., Java, OS trust stores, and security appliances) are updated and capable of validating certificates issued under the AWS certificate trust chain. 3. Participating institutions must likewise ensure that the production API URL https://api-pesonet20.pchc.com.ph is whitelisted in their respective applications, firewalls and network security devices to allow traffic to pass through seamlessly. PCHC strongly recommends DNS‑based whitelisting using the fully Qualified Domain Name (FQDN), as the underlying Public IP addresses may change without prior notice. Moreover, IP allowlisting is not considered a strong security control, as it relies on network location rather than verifiable identity, increases operational and security risk in dynamic environments, and is therefore not suitable as a primary control in accordance with our security policy and industry best practices. 4. In connection with this activity, PCHC has likewise configured and deployed the same API security solution in the PESONet UAT environment (https://api￾pesonet20.pchcdev.com) to give participating institutions sufficient opportunity to validate their respective systems prior to production implementation. 5. The new API security solution shall be deployed in production at the end-of-day of Friday, March 27, 2026. 6. Participant institutions are requested to coordinate with their respective network administrators to ensure that all necessary configurations are completed prior to the implementation date. 7. For any concerns or inquiries regarding this scheduled implementation, the following PCHC officers may be contacted: Name Email Tel no Johndale Regalado johndaleregalado@pchc.com.ph 8537-2708 James Mathias Pante jamespante@pchc.com.ph 8537-2709 Raymond Angeles raymondangeles@pchc.com.ph 8537-2722 Maxi Torrecampo maxitorrecampo@pchc.com.ph 8537-2710 Ley Julian leyjulian@pchc.com.ph 8537-2713 8. Your full cooperation in implementing this update is greatly appreciated and will help ensure the continued secure and efficient operation of PESONet. 9. Please be guided accordingly.

March 19, 2026 T O : All PDDTS Participating Institutions R E : BRIEFING ON THE COMPLETION OF PDDTS USER INTERFACE ENHANCEMENT 1. PCHC has recently completed several enhancements to the Philippine Domestic Dollar Transfer System (PDDTS) Front-End Application, undertaken in response to feedback gathered from the 2024 PDDTS/PvP Participant Satisfaction Survey. 2. The survey, commissioned by the Bankers Association of the Philippines (BAP) Operations Committee (OpsCom) and conducted in late 2024, collected comments and suggestions from PDDTS participants covering various aspects of the system, including the PDDTS User Interface, system and API enhancements, as well as updates to governance, business rules, and operating guidelines. 3. In response to these inputs, PCHC has prioritized enhancements to the PDDTS Front-End aimed at improving system usability, navigation, reporting, validation, and workflow within the PDDTS/PvP platform, including the following: a. Editing of transactions prior to authorization b. Simplified UI screens and navigation c. Advanced filters and enhanced report generation d. Expanded report modules and availability of historical reports e. “Save Template” feature for manual entries f. BIC validation and lookup upon entry. 4. In preparation for the inspection, testing, and rollout of these enhancements, PCHC will conduct a briefing via Zoom on 25 March 2026 at 10:00am to orient PDDTS participants on the completed enhancements, the User Acceptance Testing (UAT) activities, and the corresponding rollout process. 5. Each participating institution may send at least three (3) representatives, preferably from the Operations, Information Technology, and Business units. 6. Participating institutions are requested to send the names and email addresses of their representatives to Ms. Monet Paguirigan at monetpaguirigan@pchc.com.ph no later than 24 March 2026. 7. The Zoom meeting details shall be sent separately to the registered participants. 8. We look forward to your continued support and cooperation.

March 9, 2026 T O : All Clearing Banks/Institutions R E : Activation of the Web-Based CICS FES Maker-Checker Functionality 1. PCHC continually enhances its systems and operational controls to further strengthen security and safeguard the integrity of clearing operations. 2. In line with this objective, PCHC will activate the Maker-Checker Module in the Web￾based CICS Frontend System (FES). This module is an existing system feature that introduces a dual-authorization workflow whereby transactions initiated by a designated “maker” in the FES are subject to validation and approval by a designated “checker” prior to completion. 3. The activation of this feature adds an additional control layer at the FES, is reinforcing existing control points, strengthening accountability in transaction processing, and further mitigating operational and insider-risk exposures through a dual authorization workflow. 4. To facilitate a smooth transition, the module will first be activated in the User Acceptance Testing (UAT) environment. PCHC will conduct a UAT for all system users from 16 March to 27 March 2026 to allow participating banks to experience, assess, and validate the operational changes resulting from the activation of the maker￾checker workflow. 5. PCHC will provide the following to participating institutions via email: • UAT environment access details • User credentials • Updated CICS FES user guide • Test scripts • UAT sign-off form to confirm system readiness 6. All accomplished sign-off forms must be submitted on or before 31 March 2026 via philclear@pchc.com.ph . 7. For clarifications, inquiries or concerns, participants may contact any of the following: Contact Person Email Telephone Number Ruben Conseja rubenconseja@pchc.com.ph 8537-2711 Royette Delos Reyes royettedlreyes@pchc.com.ph 8537-2707 Maxi Torrecampo maxitorrecampo@pchc.com.ph 8537-2710 Ley Julian leyjulian@pchc.com.ph 8537-2713 8.

February 26, 2026 T O : All Clearing Banks/Institutions R E : CLARIFICATION ON NEGOTIABILITY LIMITATION AND EXEMPTIONS APPLICABLE TO MANAGER’S CHECKS 1. In view of the increasing number of inquiries on the treatment of stale-dated checks and the applicability of negotiability limitations, this Circular reiterates the relevant rules and clarifies the exemptions applicable to Manager’s Checks, for the guidance of all participant banks A. Ordinary Checks 1. Period for Presentment Ordinary checks may be presented for deposit or clearing within 179 days from the date of issue, subject to the depository bank’s cut-off time for acceptance. This cut￾off may be earlier than the CICS clearing cut-off of 4:30 PM. 2. Stale-Dated Checks Checks presented beyond 179 days from the date of issue are considered stale￾dated, technically defective, and must not be accepted for deposit or clearing. 3. Return of Inadvertently Paid Stale-Dated Checks If a stale-dated check is inadvertently accepted and paid by the drawee bank, it may still be returned to the presenting bank upon a verified complaint by the issuer, provided the return is made within 180 days from the date of clearing. • Such returns shall be settled through a charge slip. • Acceptance by the presenting bank is mandatory. B. Manager’s Checks Participant banks are reminded that Manager’s Checks are exempt from the limitations applicable to ordinary checks, as follows: 1. Negotiability Period Manager’s Checks are generally not subject to stale-dating and may be negotiated even beyond 180 days from the date of issue, UNLESS, the Manager’s Check itself expressly provides a validity period or states that it is valid only up to a specified date. In cases where a Manager’s Check bears an explicit validity restriction or expiry date, such restriction shall prevail, and the exemption from stale dating shall not apply beyond the stated validity period. 2. New Check Design Implementation Notwithstanding the mandatory implementation of the new check design effective 1 May 2024, the following remain acceptable for deposit and clearing: o Manager’s Checks issued in the old format (e.g., without individual date boxes or peso sign inside the amount box); and o Post-dated ordinary checks that were warehoused prior to the implementation date. Rationale This special treatment is accorded to Manager’s Checks because they are issued by a participant bank and are guaranteed to be funded upon issuance. Moreover, their validity can be readily verified by the depository bank with the drawee bank. 2. For information and guidance. We trust in everyone’s understanding and continued cooperation
