AAC Technologies Holdings Inc. (2018.HK) - BCG Matrix Analysis: Dogs

Dogs - Standard plastic lenses face margin pressure

The legacy plastic lens business contributes 5% to group revenue (FY latest: RMB 240 million of RMB 4.8 billion total). The market for low-end 4P and 5P lenses is contracting at an estimated -5% CAGR globally as demand shifts toward higher-specification camera modules (6P/7P and glass-aspheric lenses). AAC's estimated global market share in this commoditized segment is ~4%, with unit shipment volumes down 12% year-over-year. Gross margin for the plastic lens unit has compressed to ~10%, below the company average of ~24%, driven by price-led competition from low-cost producers in Southeast Asia and China and excess industry capacity. Operating income for the unit is marginally positive but yields a sub-5% ROI once allocated overhead and legacy facility costs are included. Fixed-cost absorption is deteriorating as utilization falls below 60% in older plants; depreciation and maintenance consume a high percentage of the modest contribution margin.

Dogs - Legacy voice coil motors lose relevance

The standard voice coil motor (VCM) product line for entry-level smartphones now represents ~2% of total group revenue (approximately RMB 96 million). Market growth for basic VCMs is flat to negative (0% to -2% CAGR) amid adoption of integrated camera actuators and MEMS-based solutions. AAC's share in this low-end VCM category is under 3% globally; the category is highly fragmented with intense price sensitivity. Reported operating margin for the legacy VCM unit is ~5%, materially below AAC's corporate target margin of 20%. Management has reduced capital expenditures for this segment to zero in the current planning cycle, and R&D allocation has been redirected to advanced closed-loop actuators (LRA/voice coil hybrids) and MEMS focusing technologies.

Key financial impact indicators and near-term trajectory:

• Expected revenue decline from legacy plastic lenses: -30% over next 2 years if no repositioning.
• Expected EBITDA contribution from both legacy units combined: <1% of consolidated EBITDA by year-end.
• Write-down risk: accelerated depreciation and potential impairment of legacy tooling estimated at RMB 50-120 million.
• Free cashflow relief from CAPEX cuts in VCMs: ~RMB 40-60 million reallocated to advanced optics & actuators R&D.

Recommended operational measures (current management moves observed):

• Gradual phase-out of legacy plastic lens production lines; redeploy high-capacity assets to precision glass and aspheric lens production.
• Zero CAPEX and minimal OPEX funding for commodity VCM lines; reassign engineering headcount to closed-loop actuator development.
• Inventory rationalization: target inventory reduction of 25% in legacy SKUs within 12 months to lower carrying costs.
• Customer segmentation: maintain contractual supply for strategic OEMs while exiting spot-price-driven low-margin accounts.
