What's happening?
Shares of Sodastream (SODA) are trading 20% lower on Tuesday after the company issued preliminary third-quarter results  that came in below  expectations.

Why it's happening
Sodastream's third-quarter revenue is now expected to reach $125 million. This is not only below the year-ago quarter's $144 million top line, it's also far beneath Wall Street's expectations for $154.4 million in revenue. Analysts had also expected $17.5 million in operating earnings, and Sodastream's anticipated $8.5 million is less than half that. Sodastream made no bones about its miserable performance -- CEO Daniel Birnbaum said that the company is "very disappointed in our recent performance," which was blamed on weak U.S. demand due to a lack of customer growth.

The company is in the middle of a strategic shift toward focusing more on health and wellness, and will share more details on this strategy during the third quarter's conference call later in the month.
