Shares in Nintendo Co. fell the most in nine months on Friday after the firm missed estimates for quarterly profit and forecast full-year earnings that were short of expectations, raising concern about demand for its Switch game console.

The shares fell as much as 4.7 percent in early trading in Tokyo, in the biggest intraday drop since Apr. 26.

A day earlier, Nintendo reported operating income of ¥168.7 billion ($1.5 billion) for the three months ended December, but that underwhelmed against the ¥175.4 billion average projection.
