Third Quarter2021Guidance

The following statements are forward looking statements based on current expectations and involvedrisks and uncertainties,some of which are set forth under "Forward-LookingStatements" below.The Company expects(in according with IFRS):

Revenue toincreaseby 2% to 4% QoQ.

Gross margin to range from 32% to 34%.

Dr. Gao Yonggang,Chief Financial Officer of SMIC commented:

"The Company's key financial metrics were better than expected in the second quarter. Revenue in the second quarter was $1,344 million,an increase of 21.8% quarter over quarter and an increase of 43.2% year over year. Gross margin was 30.1%,up 7.4 percentage points quarter over quarter,and up 3.6 percentage points year over year.

Revenue in the third quarter is expected to grow 2% to 4% sequentially,and gross margin is expected to range from 32% to 34%. Based on the first-half results and the second-half outlook,and under the uncertain assumption of a relatively stable external environment,we now raise our annual revenue growth target and gross margin target to be around 30% respectively. The adverse impact of advanced technology to the company's overall gross margin is expected to decrease to around 5 percentage points,due to depreciation and amortization allocated to more output.

The company still faces impact brought by the Entity List,and there are still uncertainties with our expectations in indicators. We will do our best to solve the problems,to ensure operation continuity and improve performance,for a better return to our shareholders."

Dr. Haijun Zhao and Dr. Liang Mong Song,Co-CEOs of SMIC commented:

"Since being placed on the Entity List last year,SMIC has been proceeding forward through difficult circumstances,and the entire company has been working hard. In terms of operation continuity,we are actively working with our suppliers to ensure that our commitments to customers are met,and the risks of uncertainty of mature technology is further reduced. In terms of capacity expansion,its progress is rollout as planned. However,uncontrollable factors such as license approvals,supply chain tightness,and logistics impacted by the epidemic have also inevitably affected the equipment arrival times. The company will make every effort to optimize the internal procurement process and speed up the efficiency of capacity installation,in order to shorten the procurement cycle as much as possible and reach production as soon as possible.

We understand that people have high expectations for SMIC,but there is no shortcut or leaping forward in the semiconductor manufacturing industry. We will take one step at a time,grasp our own advantages in specific market segments,improve our core competitiveness and enhance customer satisfaction."
