The Lead: Silicon Valley tech companies building on 2014 IPO pipeline

Silicon Valley is still waiting for its first non-biotech initial public offering of 2014, but the path to an IPO is beginning to get crowded with Friday's public filing by Sunnyvale wireless-networking company Aerohive Networks.

Aerohive publicly filed for an IPO on Thursday, suggesting its goal is to raise $75 million, though neglecting to give a projected share count or initial price range. The 8-year-old enterprise wireless-networking company, which will list on the New York Stock Exchange under the ticker symbol HIVE, competes with similar Silicon Valley companies such as fellow Sunnyvale company Ruckus Wireless, which raked in $126 million at a valuation of $1.2 billion in a 2012 IPO. Ruckus closed Friday at $13.52, 9.9 percent lower than its IPO price of $15.

Aerohive concentrates on the health care, government and retail sectors, and has amassed 11,500 customers, according to its filing with the Securities and Exchange Commission. The company has exhibited strong revenue growth, doubling its sales in 2011 and 2012 and reporting $76.9 million in total revenues in the first nine months of 2013, a higher total than in all of 2012. Net losses have grown as well, though, from $14.8 million in 2011 to $24.7 million in 2012 and $25.4 million in the first three quarters of 2013.

Aerohive has generated more than $100 million in venture funding from the likes of Northern Light Venture Capital, Lightspeed Venture Partners, New Enterprise Associates, KPCB and DAG Ventures, which maintain ownership of narly 75 percent of the company.

The IPO market in 2014 has been dominated by biotechs, including two Bay Area companies that have gone public in the past month. Silicon Valley companies are reportedly lining up to jump into the market, however.

Quartz, the New York Times and the Wall Street Journal reported late last month that Los Altos cloud-storage company Box had filed privately for an IPO, a process that has become increasingly common since it was implemented with the passing of the Jumpstart Our Business Startups Act in 2012. The company, which CEO Aaron Levie describes as "a universal, lifetime backup and sharing service," has been a hit with enterprise customers and venture capitalists, who have poured nearly $400 million into the company, with its most recent round valuing Box at $2 billion. Box rival Dropbox also appears to be on the path to an IPO, recently raising a monster funding round that could have raised up to $450 million at a valuation approaching $10 billion and announcing a high-profile hire to fill a new chief operating officer role.

San Mateo action-camera company GoPro has also secretly filed for an IPO, though the company publicly announced the move last week. Mountain View-based Coupons.com has publicly filed for an IPO, and updated its filing Friday with more revenue numbers, though the Web company has still not provided a share count or price range.

Outside of tech, Burlingame airline Virgin America has reportedly chosen banks for an IPO that it hopes to exercise in the latter half of 2014, using the funds to expand its fleet from just more than 50 airplanes to more than 100. Timothy Keating, founder and CEO of pre-IPO investment company Keating Capital, said in a blog post earlier this week that he expects the IPO market will continue to boom in 2014 despite recent Wall Street volatility, following up on 2013's performance, which was the strongest since the dot-com bust.

"Large public companies are struggling to grow their top lines," Keating wrote. "In a slow growth economy with full stock market valuations and no competition from fixed income, public investors are -- and almost assuredly always will be -- willing to pay a premium for the 20-30%+ expected revenue growth that is typical of many venture capital-backed technology companies that have recently gone public."

SV150 market report: Twitter gains ahead of first lockup expiration

The tech company with the most high-profile IPO of 2013, Twitter, will allow employees to sell their first batch of stock Saturday, but the company's share price still gained Friday as Wall Street closed out its best week of the year despite a slight overall decline for Silicon Valley stocks.

San Francisco-based Twitter advanced 1.7 percent to $57.44 Friday, remaining more than twice as high as the $26 price commanded in its November 2013 IPO. With prices at those levels, it will be hard for Twitter employees to avoid putting more shares on the market as the option becomes available Saturday, when 9.9 million employee shares will be eligible for sale on the open market. That is just a small percentage of the shares employees hold, the Wall Street Journal points out -- about 1.8 percent -- which should help avoid a sudden glut of Twitter shares on the market, which could bring down the price. The bigger date is May 6, when the other 474.7 million shares owned by Twitter employees begin to unlock. While Twitter employees await their windfall, the social network is facing a crackdown in Venezuela, where protests have led to the government blocking images from the company's website.

Tesla Motors dipped 0.7 percent to $198.23 amid concerns about a slowdown in its California sales and an investigation into a Toronto garage fire involving a Model S, which the Palo Alto company said did not involve the car's battery nor charging equipment. Netflix lost 0.2 percent to $435.51 as the second season of "House of Cards" debuted on Valentine's Day, with the buzz for the Los Gatos company's show growing and creating concerns about bandwidth this weekend. Cisco bounced back from Thursday's post-earnings slide, gaining 1.3 percent to $22.56; Agilent fell 8 percent to $55.25 after the Santa Clara company revealed flat earnings Thursday, and San Jose's Brocade gained 2 percent to $9.62 after beating expectations in its quarterly report.

Apple held relatively steady, dropping 0.1 percent to $543.99 while winning dismissal of one lawsuit and reportedly failing to come to terms with Samsung in a mediation attempt; the Cupertino company's iBeacon technology has been installed in two Southern California ballparks in preparation for the 2014 Major League Baseball season. Google topped $1,200 for the first time and gained 0.2 percent to $1,202.80 while revealing its concessions to the European Union's antitrust concerns and looking ahead to providing a 10-gigabit Internet connection with its Google Fiber service. eBay dropped 0.3 percent to $54.77 and Facebook fell 0.4 percent to $67.09 as filings showed the companies were popular with hedge funds in the fourth quarter, and Yahoo fell 0.8 percent to $38.23 after acquiring yet another young startup.
