(Reuters) - Super Micro Computer's shares fell 5% on Wednesday after the AI server maker announced the pricing of its public stock offering, selling the shares at a discount to their most recent closing price. 

The slide marks the fifth consecutive session of decline for the stock, erasing about 28% from the company's market capitalization over the period and lowering its share price to $862. 

Super Micro, one of the top sellers of AI-optimized servers and a beneficiary of the boom in AI services, is selling 2 million shares of its common stock at $875.00 a piece and expects to make $1.75 billion in gross proceeds, according to an exchange filing late on Tuesday. 

The stock had ended 9% lower, at $910.97 on Tuesday, after Super Micro announced the stock offering. 

Shares of the San Jose-based company have more than tripled so far this year. 

Super Micro's ability to quickly develop AI-compatible servers as well as its in-house liquid cooling technology have helped the company turn into a key data-center supplier. 

The recent surge in the firm's market value led to its inclusion in the S&P 500 index on Monday. That means exchange-traded funds that track the index must now own Super Micro's shares. 

The company raised $1.7 billion last month in a convertible bond offering to fund its expansion plans.
