Bank of America's latest analysis of Apple's $Apple(AAPL.US) iPhone manufacturing costs reveals promising trends for the company's margins. The study highlights significant cost reductions in the iPhone 16 Pro models, with manufacturing costs for the iPhone 16 Pro Max being 5% lower than its predecessor, contributing to a 320 basis point improvement in gross margins. When memory costs are adjusted, the savings increase to 8%. The base iPhone 16, however, shows a 10% increase in manufacturing costs due to AI and camera upgrades. Potential savings could also come from insourcing components like the baseband modem. These findings support BofA's positive outlook on Apple's margin resilience and its expectation of strong iPhone upgrade cycles in fiscal 2025 and 2026. Apple shares, currently trading at $237.87, have risen nearly 30% over the past year. The company's consensus price target is $245.17.$Apple(AAPL.US)
