1244 ET - Fair Isaac investors are selling off the stock after revenue and guidance came in below Wall Street estimates, UBS analysts say. The company behind the FICO score logged fiscal 3Q sales of $674.2 million versus the Street's consensus of $679.2 million. It guided for $2.53 billion in full-year sales, which was a raise from its prior outlook, but was still below analysts' projection of $2.56 billion. The misses are being compounded by investor concerns about rising competition from VantageScore, a credit-scoring alternative that is being adopted by more bureaus, the UBS analysts say. Shares fall 16%.
