What are the benefits to underwriters in a secondary offering?
Your impression about banks and bankers is very wrong.  Wall street banks can and often do lose in transactions.  In fact, banks go bankrupt and/or require massive bailouts to survive because they sometimes lose a ton of money.  The business of investment banking often involves bearing risk for customers, which, by definition, means they lose some of the time.  Generally the risks they take on individual transactions are not large enough to bring the whole bank down, but sometimes they are.  Banking is a job like any other, except that it has more risk than most. Anyway, to your point, how do underwriters make money on shares that fall in value before the sale?  On the commission.  The issuing company will normally pay the investment bank a percentage of the funds raised in the offering, regardless of the price.  Of course, it's possible for the bank to still lose money if their contract stipulates a minimum price and they are not able to meet it.  In that case, the bank may lose on that offering, contradicting your preconceived notion. By the way, one other question implicit in your post: Why was the secondary offering considered bad news?  If the CEO and other insiders have private information that indicates that the stock is overvalued, then doing a secondary offering at the inflated price will greatly enrich them.  Because this happens some times, investors are wary about secondary offerings.  This makes companies that would otherwise do a secondary offering shy away from it, even if shares are not overpriced.  Therefore if a company is doing a secondary offering, the market is likely to worry that the stock is overvalued even at a reduced price.
