On 5 September 2025, the Hang Seng Index (HSI) rose by 359 points, a 1.4 % gain, while the Hang Seng Technology Index (HSTI) climbed 108 points, a 1.9 % increase. In the same session, XINYI SOLAR posted a gain of over 7 %. Within this context, CALB, along with peers such as SINO BIOPHARM, CHOW TAI FOOK, 3SBIO, and KEYMED BIO‑B, reached new intraday highs, signalling investor confidence in the company’s product pipeline and its role in the expanding electric‑vehicle (EV) and energy‑storage markets.

Sectoral Developments Impacting CALB
GST Policy for EVs – A decision by the GST Council on 4 September retained a concessional 5 % tax rate for electric cars. While this policy primarily benefits vehicle manufacturers, it also supports battery suppliers such as CALB by sustaining demand for EV powertrains.
Battery Plant Expansion in India – On 4 September, a Japanese firm, TDK Corporation, inaugurated a lithium‑ion battery plant in Haryana, India, with an investment of ₹3 000 crore. The expansion of battery manufacturing capacity in India is expected to increase the demand for high‑quality battery cells, a core product of CALB.
Government Subsidy Enforcement – The Delhi High Court ordered the Delhi government to disburse promised subsidies to EV buyers. While the directive addresses consumer incentives, it underscores a regulatory environment that is increasingly supportive of EV adoption, indirectly benefiting battery producers.
Operational and Strategic Footnote
CALB’s business model centers on the manufacture of lithium‑ion power batteries, battery management systems, and energy‑storage solutions for vehicles and other applications. The company’s website, www.calb-tech.com , provides detailed information on its product offerings and technological capabilities, which are aligned with global trends toward electrification and renewable energy integration.
Conclusion
In a trading environment marked by sector‑specific policy support and broader market volatility, CALB Group Co Ltd has maintained a trajectory of share price appreciation and market recognition. The company’s compliance with disclosure obligations, coupled with its strategic positioning in the EV and energy‑storage ecosystems, continues to attract investor interest.
