Ionics EMS, Inc. is a Philippines-based, publicly listed Electronics Manufacturing Services (EMS) and Original Design Manufacturing (ODM) provider founded in 1974 and headquartered in Calamba, Laguna. The company operates 8 production and supply chain facilities across the PEZA-accredited Special Economic Zones of Laguna, supplying end-to-end manufacturing, supply chain management, and design engineering services to global OEMs in seven primary verticals: Telecommunication, Industrial, Automotive, Medical, Consumer Electronics, and Computer/Peripherals.

Ionics extends its service EMS model with proprietary ODM products, including the PlugComputer (2009), the Ionics IoT Platform (2017) for factory and building automation, the ADA-TMU (Advanced Data Analytics – Transformer Monitoring Unit) co-developed with First Philec in 2024 for smart grid applications, and an Automatic Voltage Regulator for Distribution Transformers that received a Philippine patent in 2024. The company holds ISO 9001:2015, ISO 14001:2015, ISO 13485:2016 (medical), IATF 16949:2016 (automotive), and ISO 28000:2022 certifications, which qualify it for regulated OEM programs.
Revenue is generated through B2B contract manufacturing, NPI, and engineering service fees on a quote-based engagement model with global OEM customers, accessed via a direct enterprise field sales motion. Distribution is entirely direct with no intermediaries. The company is led by President Raymond Qua following the passing of founder Larry Qua, who held the chairman-president-CEO role for 50 years. Revenue is not publicly disclosed; the firm's scale (1,001-5,000 employees, 8 facilities, 100+ country reach) and inclusion in 2024 global top-10 EMS lists place it as a mid-tier global EMS incumbent with selective vertical expansion into energy transition.
