Kepler Cheuvreux Downgrades BE Semiconductor to Hold as Hybrid Bonding Hype Settles

Kepler Cheuvreux has shifted its stance on BE Semiconductor (Euronext: ASMI), downgrading the stock from Buy to Hold. The broker argues that the enthusiasm around hybrid bonding technology has already been factored into BESI's current valuation, leaving limited room for further short-term gains.

Analyst Ruben Devos adjusted the price target down to €154 from €160, reflecting a more conservative outlook. His forecasts on earnings are below consensus, signaling caution amid what he sees as tight margins for potential upgrades in the near future.

Devos pointed out that the market seems to be pricing in optimistic assumptions regarding hybrid bonding adoption, competitive pressures, and the recovery of BESI's mainstream assembly operations. This sets a high bar, reducing tolerance for setbacks.

While hybrid bonding technology remains strategically key, transitioning to high-volume manufacturing (HVM) poses complex challenges at the system level. Devos highlighted that high-bandwidth memory (HBM) customers may hesitate, opting for more gradual, multi-sourced implementation compared to investor expectations.

With BESI trading near historic peaks, the analyst prefers a neutral outlook until clearer execution progress and order momentum emerge. The recent rally since mid-2025, fueled by excitement over advanced packaging and a hopeful memory market upcycle, may have pulled forward anticipated gains.

Growth estimates for 2026 through 2028 have been trimmed by 5% to 11% on sales, with earnings per share forecasts lowered 11% to 18%. These cuts stem from cautious views on how quickly hybrid bonding will penetrate key segments like HBM, and concerns over competitive dynamics.

Devos highlighted that thermo-compression bonding still dominates as the practical method for HBM production today. Memory makers show little appetite for requalification risk during a period when fab utilization is at record levels, favoring proven methods.

He also noted the potential for SK Hynix to focus on capital efficiency rather than speed, prolonging the current bonding methods and delaying hybrid bonding orders. When transitions occur, Korean and Asian equipment suppliers might be the main beneficiaries.

The broader assembly business has faced headwinds, estimated to have shrunk about 15% in 2025. The outlook suggests only a mild rebound in 2026 as AI-related capex may crowd out consumer electronics spends, while China's previous tailwinds taper off.

Lastly, forex and product mix challenges could weigh on BESI's performance more than consensus anticipates. On valuation, BESI's next-twelve-month EV/EBIT ratio hovers around 41x, nearly two standard deviations above its five-year average, raising questions about stretched multiples in the current environment.
