We are pleased to inform you that Apollo Micro Systems Limited, in the ordinary course of its business, has successfully handed over the indigenously developed Safety & Detonation Device (SDD) to the Indian Navy. The handover ceremony was conducted in the presence of Rear Admiral Rupak Barua, VSM, Director General of Naval Inspection (DGNAI), Indian Navy, along with senior officers of the Indian Navy and the leadership team of Apollo Micro Systems Limited. Prior to the indigenous development of the Safety & Detonation Device (SDD), the Indian Navy relied on imports for this critical equipment. The successful indigenous development of the SDD is expected to result in a significant reduction in procurement costs for the Indian Navy, while also contributing to enhanced self-reliance in the defence sector. The handing over of the SDD marks the successful culmination of a rigorous design, development, qualification and validation journey and stands as a proud testimony to what Indian industry can deliver when entrusted with the most safety-critical elements of a weapon system. The Company expects this indigenisation success to translate into a healthy pipeline of production orders and follow-on programmes, as the Indian Navy and other users progressively induct indigenous safety and arming solutions across their weapon inventories. AMS is fully geared, in terms of design strength, manufacturing infrastructure and quality systems, to support series production and lifecycle sustenance of the SDD and its derivatives. A press release to this effect is also enclosed. This update is provided for the information to our shareholders. We request you to kindly take the above on record.

Apollo Micro Systems Limited | IDA Mallapur, Hyderabad – 500 076 | www.apollo-micro.com Press Release | Page | 1 of 3 NSE: APOLLO │ BSE: 540879 A SAFETY-CRITICAL SYSTEM AT THE HEART OF NAVAL FIREPOWER The Safety Arming Device is among the most critical and unforgiving sub-systems of any modern munition. It is the final guardian between a weapon and its target ensuring that ordnance remains absolutely safe through storage, handling, transportation and launch, and arms only when every prescribed condition of a valid engagement sequence is unambiguously satisfied. In the demanding maritime environment characterised by shock, vibration, humidity, salt-fog and severe electromagnetic conditions the reliability of the Safety Arming Device directly determines both the safety of the platform and its crew, while ensuring the assured performance of the weapon at the moment of truth. For decades, systems of this criticality were accessible to India largely through import channels, with attendant constraints of cost, availability, obsolescence and denial regimes. Indigenous mastery of Safety Arming technology is therefore not merely an engineering achievement it is a strategic capability that secures the operational readiness and sustenance of the Indian Navy's weapon inventory on sovereign terms. PROVEN THROUGH RIGOUR: HOW APOLLO ESTABLISHED THE CAPABILITY 100% Application Earlier Opportunities Cost Reduction Indigenous Varied Weapons Imported MRO and New Significant Content and Missile Weapon and Programs Missile Programs Working in close partnership with the Indian Navy's professional teams, AMS took the SDD from concept to a fully proven, deliverable system. The device has been engineered to stringent international fuze-safety design philosophies and has been subjected to an exhaustive validation, including: • Design conforming to globally accepted fuze safety and arming principles, with independent, redundant safety interlocks and out-of-line safety architecture; • Comprehensive environmental qualification mechanical shock, vibration, temperature extremes, humidity and marine environmental stress screening; • Electromagnetic compatibility and interference testing appropriate to shipborne and underwater weapon environments; • Extensive functional, endurance and safety-margin testing, followed by joint evaluation and acceptance trials with Indian Navy. Through this journey, AMS worked shoulder-to-shoulder with the Indian Navy to convert a clearly articulated operational problem statement into a certified, production-ready indigenous solution exemplifying the collaborative industry–Navy model championed under the Swavalamban framework.

Every successfully indigenised safety- critical sub-system deepens the nation's strategic autonomy, compresses supply chains, and builds a sovereign industrial base for the future. For Apollo Micro Systems, the SDD establishes a proven, qualified capability in safety and arming technologies a capability that is directly extensible across a wide spectrum of naval and tri-services munitions, underwater weapons, missiles and guided ordnance. The Company expects this indigenisation success to translate into a healthy pipeline of production orders and follow-on programmes, as the Indian Navy and other users progressively induct indigenous safety and arming solutions across their weapon inventories. AMS is fully geared, in terms of design strength, manufacturing infrastructure and quality systems, to support series production and lifecycle sustenance of the SDD and its derivatives. “The Safety & Detonation Device is where engineering meets absolute responsibility there is no margin for error. Handing over this fully indigenous, fully proven system to the Indian Navy is a moment of deep pride for every member of the Apollo family. We thank the Indian Navy for its trust and partnership, and we see this as the beginning of a much larger journey in [Showing first 8,000 characters — download PDF for full document]
