Sanofi (NYSE:SNY) reported earnings from the quarter that were below analyst expectations, driven (in part) by a strong euro and currency conversion issues. That said, there were other disappointments as well -- Lantus, Sanofi's flagship insulin product, was up 13.5% in constant currencies to just under 1.5 billion euros, a little lighter than analysts had anticipated.

Nonetheless, Sanofi's management is guiding for 4% to 7% revenue growth (at constant currencies) over the next year, driven by several potential exciting pipeline candidates, including U-300 and alirocumab.
