A biotechnology company is a company whose products or services primarily use biotechnology methods for their production, design or delivery. The United NationsConvention on Biological Diversity defines 'biotechnology' as: "Any technological application that uses biological systems, living organisms, or derivatives thereof, to make or modify products or processes for specific use." In other words, biotechology can be defined as the mere application of technical advances in life science to develop commercial products.
The following is a list of the top 25 independent biotechnology companies listed on a stock exchange ranked by Market Capitalization in Q2 of 2012. It additionally details their market capitalization in Q2 of the previous year (2011), from which the change in value over the year can be calculated.
Note that it does not include biotechnology companies that are now owned by, or part of, larger pharmaceutical groups - such as Genentech (owned by Roche), Genzyme (Sanofi), or MedImmune (AstraZeneca). It should be viewed as an update and complementary to the previous table below.
§ - Acquired by Bristol-Myers Squibb in a $7 billion deal completed Aug 8 2012 (therefore no longer independent in this list going forward).
NOTE: Market Cap is an indication of the perceived value of the company (&/or its technology) and not necessarily a measure of its size, sales or number of employees; it is indicative of both current and future scale and profitability of the company. The year-on-year change in its value is indicative of the (real or perceived) performance or progress of that company over that year.
Examining the list of the top 100 such companies, below, shows that many have negative income. This is consistent with the notion that only one in ten biotechnology companies were considered profitable in mid-2005.
