Record Storage Contract and Model Blitz Fail to Lift BYD’s Slumping Shares

BYD secures 11.3 GWh battery storage contract in Abu Dhabi, unveils Denza Z9S, Fangchengbao Shark, and Seagull Gen2 in China, while H-shares remain down 12.55% year-to-date.

BYD is firing on multiple fronts – from a gigantic battery storage deal in the Arabian desert to a wave of new vehicle registrations in China – yet the stock remains mired in a sharp downtrend. Hong Kong-listed H-shares nudged up 3.01% to €9.58 on Friday, but the year-to-date loss stands at 12.55% and the one-year slide at 26.87%. With the shares still 35.27% below last July’s 52-week high of €14.80, the market has so far shrugged off the operational momentum.

The centrepiece of this week’s news is a 11.275-gigawatt-hour battery storage supply agreement with Abu Dhabi state utility Masdar. The contract is part of the so-called Round The Clock project, which pairs a 5.2-gigawatt solar plant with 19 GWh of battery storage to create the world’s largest integrated solar-plus-storage installation. BYD will deploy its Haohan storage system built around the latest-generation Blade battery, a single cell with 2,710 ampere-hours that lifts per-cell capacity by more than 300% while slashing battery management complexity by 70-80%. The system is designed to withstand sand, dust and temperatures ranging from -30°C to 55°C – essential for desert operation. Rival Chinese group Sungrow had already secured 7.5 GWh for the first construction phase, meaning two Chinese companies will handle the entire 19-GWh project, locking out international competitors.

On the vehicle side, BYD’s premium Denza brand registered the new Z9S sedan with Chinese authorities on July 10. Measuring 5,090 mm long with a 3,025-mm wheelbase, the Z9S targets the same segment as the Xiaomi SU7. Two powertrain options offer 320 kW or 370 kW, both hitting a top speed of 250 km/h. Denza’s June deliveries reached a record 20,352 units, up nearly 29% year on year, although first-half volume of 66,541 vehicles still trails the prior-year period by 16.65%. Separately, BYD’s off-road brand Fangchengbao has filed its Shark pickup for the Chinese market. The plug-in hybrid measures 5,457 mm long, uses a 1.5-litre turbo engine paired with three electric motors delivering a combined 436 hp, and sprints to 100 km/h in 5.7 seconds. With a 29.58-kWh LFP Blade battery offering 100 km of electric range (NEDC), a towing capacity of 2,500 kg and pricing expected around 200,000 yuan, it will take on the Great Wall Cannon Hi4-T and Nissan Frontier Pro PHEV. In the city-car segment, the second-generation Seagull grows markedly to 4,205 mm in length and gains a top-spec roof-mounted lidar sensor with the DiPilot 300 driver-assistance suite on Nvidia Drive Orin hardware. Starting at 69,800 yuan (roughly $10,000), it is due in late Q3 2026. The Seagull was the world’s fifth-best-selling EV in the first five months of 2026, with over 125,000 units sold globally.

International expansion is accelerating. In the UK, BYD’s first-half registrations nearly doubled to 37,995 vehicles, capturing an 8.74% share of the plug-in market. The SEAL U DM-i was the top-selling plug-in hybrid, and three more models – including the Shark pickup – are scheduled to arrive. Chairman Wang Chuanfu reiterated at the June annual general meeting an overseas sales target of more than 1.5 million vehicles for 2026, helped by the ongoing ramp-up of second-generation Blade batteries that are adding 20,000 to 30,000 extra units per month since March.

Yet all this activity has failed to move the needle for BYD’s shares. The stock trades 1.81% below its 50-day moving average and 10.44% below the 200-day line of €10.70. With a relative strength index of 55.8, the technical picture is neutral, while the 30-day annualised volatility remains elevated at 41.67%. The market capitalisation stands at €86.48 billion. For a company that is simultaneously locking down historic storage contracts, refreshing its mainstream and premium line-ups, and doubling its export sales, the disconnect between corporate progress and share price performance is becoming increasingly hard to ignore.
