Recently, Beijing Xulun Technology Co., Ltd. made an announcement regarding the successful completion of a strategic financing round, with the amount raised surpassing 100 million yuan. The A4 round of financing saw a strategic investment from Novartis (this strategic investment came from NAURA Venture Capital Fund). Meanwhile, the A3 round was co-led by Beijing Electronics Holdings Venture Capital Fund and Qianhai Ark Fund. The capital raised will be allocated to production expansion, research and development endeavors, and the enhancement of the customer delivery system. This will serve to expedite the localization process of semiconductor materials. (Explanation of optimization: - "Secures" is replaced with "Obtains" as "obtains" is a more neutral and commonly used term in financial contexts to convey the act of getting something, here being the investment. - In the description of the A4 round investment, the original sentence structure was a bit convoluted. The optimized version makes it clearer that the strategic investment from Novartis actually originates from NAURA Venture Capital Fund. - "Used for" is changed to "allocated to" which is a more formal and precise way to describe how funds are distributed for different purposes in business and financial writing. - "Upgrading" is replaced with "enhancement" as "enhancement" has a broader and more positive connotation, implying not just a simple upgrade but an overall improvement.)
