BlackBerry, a leading Smartphone maker based in Canada, has seen its shares fall after the company recorded a sudden loss and did not disclose its sales figures.

Investors have expressed concerns over the lack of sales figures from the Smartphone maker in the public domain. There are worries that the Smartphone maker might not be able to regain its market share after losing customers to Apple and Android makers.

The company recorded a loss of $84 million during its first quarter of the financial year. The company also said that its subscriber base fell 4 million during the quarter. Investors have also expressed concerns over expectations of another operating loss in the current quarter.

Chief Executive Thorsten Heins said, "Today, if you look at BlackBerry, we are a leaner, more efficient company. We are confident in the ongoing success of our transformation in the coming years. We are doing the right thing."

The shares of the company fell 28 per cent or $4.02 to $10.46.
