AAC Technologies’ latest earnings call painted a picture of a company in transition, leaning on strong growth from new, higher‑margin product lines to offset pressure in its legacy acoustics business. Management highlighted double‑digit revenue expansion, outsized profit growth and robust cash generation, arguing that diversification beyond smartphones is now driving the financial recovery.
Strong Top-Line Growth
Group revenue reached RMB 31.82 billion in 2025, up 16.4% year on year as AAC reduced its reliance on traditional mobile‑phone components. The company credited a more diversified product mix, with contributions from optics, motors, sensors and automotive systems, for cushioning softer demand in parts of the smartphone market.
Substantial Net Profit Expansion
Net profit jumped 39.8% to RMB 2.51 billion, outpacing sales growth and underscoring operating leverage in newer segments. Management pointed to improved profitability in optics and the rising share of higher‑margin businesses as the key drivers behind the earnings surge.
Improved Cash Generation and Balance Sheet
Operating cash inflow climbed 38.1% year on year to RMB 7.18 billion, while free cash flow surged 65.1% to RMB 4.88 billion. Cash and cash equivalents rose to about RMB 8.61 billion and net gearing fell to roughly 2.1%, giving AAC greater financial flexibility for investment and M&A.
Heat Dissipation Breakthrough in PM Business
Heat dissipation revenue in the precision mechanics segment exploded more than 400% year on year to RMB 1.67 billion, making it one of AAC’s standout growth engines. The company launched its first fully automated production line, which delivered higher manufacturing efficiency and yield, supporting scale‑up in this promising category.
Sensors & Semiconductor Rapid Growth
The sensors and semiconductor division generated RMB 1.57 billion in revenue, up about 103.1% year on year, confirming its status as another high‑growth pillar. AAC cited strong demand for higher signal‑to‑noise‑ratio microphones and mass production wins with major Shenzhen customers as the main catalysts.
High-End Optics Progress
Optics revenue totaled RMB 5.73 billion in 2025, with a clear shift toward more sophisticated products. Shipments of 7‑element and hybrid lenses reached around 15 million units, over 40% of modules were 32‑megapixel or higher, optical image‑stabilization modules nearly doubled and periscope modules moved into mass shipment.
EMD & Motor Growth Momentum
Combined EMD and precision mechanics revenue came in at RMB 11.77 billion for the year, with second‑half revenue up about 17.6% to RMB 7.14 billion. AAC reported double‑digit shipment growth and rising market share for X‑axis linear motors in mid‑ to high‑end Android smartphones, reinforcing its position in motion components.
Automotive Acoustics & System Wins
Automotive acoustics revenue grew 16.1% year on year to RMB 4.11 billion, with a respectable gross margin of 23.8% as the car segment gained scale. The company secured branded audio‑system deals, such as supplying Naim systems for Zeekr 9X, and pursued acquisitions like Hebei First Light to build vertically integrated, system‑level capabilities.
Acoustics Growth Sluggish with Margin Pressure
Legacy acoustics posted full‑year revenue of RMB 8.35 billion, up only 1.7% year on year and just 1.6% in the second half, highlighting its mature profile. Gross margin slipped to 27.6% as customer and product mix shifted toward more module projects, and management acknowledged that acoustics profitability fell short of some expectations.
Low Margins in Module Business
Within optics and modules, overall gross margin was around 11.5% for 2025, with modules themselves earning only about 4–5% gross margin. These thin economics on lower‑end modules contrast with the strength in high‑end lenses and underscore the need for mix improvement and pricing discipline in the module portfolio.
Industry Headwinds and Price Volatility
Management flagged ongoing uncertainty in the global smartphone market, with some industry forecasts calling for flat or weaker shipment trends. Volatility in memory prices and broader component‑market turmoil may weigh on demand for certain end products, especially lower‑end devices, adding a macro overhang to AAC’s traditional lines.
Uncertain Timelines for Robotics and AR/XR
AAC is investing in robotics and AR/XR technologies, but executives admitted that commercialization timelines remain unclear and visibility on near‑term revenue is limited. These areas are framed as multi‑year opportunities rather than immediate earnings drivers, leaving investors to wait for clearer monetization milestones.
M&A and Disclosure Ambiguity
The call also highlighted ongoing M&A moves, including the Far East transaction aimed at expanding data‑center cooling capabilities, but some details raised questions. References to acquisition stakes and revenue expectations varied slightly, and minor inconsistencies in cash‑flow and percentage disclosures may complicate precise financial modeling for analysts.
2026 Outlook and Strategic Targets
Looking ahead to 2026, AAC is targeting roughly 16% revenue growth while maintaining a group gross margin around the low‑20s and continuing to improve net profit and margins. Segment guidance is robust: PM/EMD revenue is expected to grow more than 30% with better margins, optics to grow about 10% with 5–10% ASP uplift and plastic‑lens margins of 30–35%, sensors and semiconductors to rise mid‑ to high‑teens, automotive acoustics to sustain double‑digit growth and broader acoustics to stabilize with margin improvement.
AAC’s earnings call overall suggested a company successfully pivoting toward faster‑growing, higher‑value components, even as legacy segments face headwinds and industry data remain mixed. For investors, the story hinges on whether heat dissipation, optics, motors and sensors can keep compounding at high rates and gradually lift group margins, offsetting softness and pricing pressure in older product categories.
