Cisco's weak revenue forecast is driving down its stock

Cisco topped Wall Street's revenue target in its fiscal Q4, but gave a lackluster business forecast for the current quarter.

Cisco's stock declined roughly 2% in after hours trading on Wednesday following the announcement.

Here's are Cisco's results:

• Revenue (GAAP) — $12.1 billion, down 4% from $12.64 billion in Q4 2016.  This is compared to analyst estimates of $12.07 billion. Cisco projected similar estimates. 
• Earnings per share (adjusted) — $0.61, on the nose of analyst estimates and a penny above's Cisco's own forecast. 
• Net income (GAAP) — $2.4 billion, down 14% from 2016.
• Projected revenues (GAAP) for Q1 2018 are below analyst expectations. Cisco projects revenues to decline 1% to 3%, which would put it around $11.8 billion. Analysts had projected revenues to stay around $12.6 billion next quarter. 
• Projected earnings per share (adjusted) meet analyst expectations. Cisco expects earnings per share of $0.59 to $0.61 next quarter; analysts had projected earnings per share of $0.60. 
• Full year revenues (GAAP) were down 2% for fiscal year 2017, with total revenues of $48 billion.
• Full year earnings per share (adjusted) for the year were $2.39.
