The June IPO market produced 30 IPOs, representing the highest monthly tally since the 65 IPOs in August 2000. June’s activity brings the count for the first half of 2014 to 132 IPOs—89% above the 70 IPOs in the first half of 2013 and the strongest pace for any six-month period since 2000.

The last week of June alone produced 11 IPOs—the second double-digit weekly tally in 2014 and the highest weekly number of IPOs since the 12 IPOs in the first week of February 2007.

Gross proceeds in June were $7.43 billion, representing the sixth highest monthly figure since 2000. The June figure brings total gross proceeds for the first six months of 2014 to $28.24 billion—two-thirds higher than the $16.86 billion raised by IPOs in the first six months of 2013.

The percentage of IPOs by emerging growth companies (EGCs) has continued its climb, reaching 89% of IPOs in the first six months of 2014, compared to 82% in 2013 and 76% in the portion of 2012 that followed enactment of the JOBS Act.

June saw a double-digit count of IPOs by venture capital–backed US issuers for the third month in 2014, bringing the year-to-date total to 62, only 10 below the tally for all of 2013. With six private equity–backed US issuer IPOs in June, the total of 23 over the first half of 2014 is two above the 21 PE-backed IPOs in the first half of 2013 and represents the highest number of PE backed IPOs in the first half of the year since the first half of 2006.

June produced nine IPOs by life sciences companies. The total of 53 life sciences company IPOs through June 30 is now three above the full-year 2013 count of 50. Following a two-month period in which life sciences company IPOs were not well received by the market—with the average April and May life sciences company declining 2% on its first day of trading—the average June life sciences company IPO produced a 17% first-day gain, and only a pair declined on their first day of trading.

Overall, broadly-defined technology and life sciences companies accounted for 73% of the year’s IPOs through June 30, up from 59% over the prior three-year period and representing the highest annual percentage since the end of the dot-com bubble in 2000.

The $94.3 million median offering size for all IPOs in the first half of 2014 was 12% lower than the median offering size of $107.4 million in 2013, although equal to the median offering size for all IPOs in 2012, and represents the lowest yearly figure since the $89.3 million median offering size in 2004. Drawn down by the $55.0 million median offering size for life sciences IPOs, the median size for VC backed IPOs in the first half of 2014 was $79.0 million—slightly higher than the $78.3 million median in 2013 but still the second lowest level since the $72.0 million median in 2006. The median size for EGC IPOs in the first half of 2014 was $88.9 million compared to $554.9 million for other IPO companies.

The percentage of profitable IPO companies declined from 55% in 2012 to 43% in 2013 and to 33% in the first half of 2014, with only 13% of 2014 life sciences IPO companies being profitable. The median annual revenue for IPO companies fell from $133.6 million in 2012 to $89.9 million in 2013 and to $78.9 million in the first half of 2014—the lowest level since the $74.5 million figure in 2007.

The average IPO company in 2014 through June 30 ended its first day of trading with a 15% gain—below the average first-day gains of 21% for IPOs in 2013 and 16% for IPOs in 2012, but still the third highest average first-day gain since 2000. Year-to-date, 25% of IPOs were “broken” (closing below the offering price on the first day)—above the 22% of broken IPOs in 2013 but only a single percentage point above the figure for the five-year period preceding 2014.

The average 2014 IPO company ended June 23% above its offering price—just shy of the average gain for 2013 IPOs at this time last year when the average 2013 IPO company had gained 25% from its offering price. Through June 30, the average 2014 IPO has gained 8% from its first day close. At June month-end, 41% of all 2014 IPOs were trading at least 25% above their offering price while almost a third were trading below their offering price.
