On Jan, 22 2026, ISDN Holdings (I07.SI) issued a supplemental announcement detailing the pricing mechanisms, internal controls and updated annual caps for its renewed continuing connected transactions with Germany-based Dirak Holding GmbH. The arrangements were first disclosed on Dec, 18 2025.

ISDN will sell “Product A” to Dirak on a cost-plus basis, applying a minimum profit margin of 10 percent. Management will review prices annually, benchmarking them against orders from independent third parties to ensure terms are at least as favourable. Prices are proposed by the business unit, vetted by the department head and approved by the assistant general manager, mirroring the process used for independent customers.

For “Product B,” ISDN will buy from Dirak at list prices applicable to all non-end-user customers. Final purchase prices are set through arm’s-length negotiations after referencing at least two comparable third-party transactions when practicable.

Historical annual caps for sales of Product A were 12 million Singapore dollars in 2023, 13 million Singapore dollars in 2024 and 15 million Singapore dollars in 2025, with utilisation rates of 57 percent, 74 percent and an expected 81 percent, respectively. ISDN projects an average annual cap growth of about 30 percent through 2028, factoring in inflation of roughly 3-4 percent, GDP growth of 2-3 percent, raw-material trends and rising orders from Dirak.

For purchases of Product B, past caps were 1.2 million Singapore dollars each year from 2023 to 2025, with utilisation of 72 percent, 70 percent and a forecast 93 percent. The company anticipates an average annual cap increase of 14 percent to 2028, reflecting inflation, GDP growth and its own production expansion.

Internal controls include monthly monitoring of transaction details by the finance department, quarterly assessment of cap usage, and annual reviews by independent non-executive directors and external auditors to confirm the deals are conducted on normal commercial terms.

The board states that no other information in the original announcement is affected.
