Earnings Call Summary

Boston Scientific reported first quarter sales of $5.2 billion, up 9.4 percent, and beat on earnings at $0.80 per share. However, management revealed major headwinds in three key franchises. The EP cardiology ablation business, which grew 22 percent this quarter, is now expected to slow to 10 percent full year as competition from Medtronic, J and J, and Abbott pressures U.S. share. WATCHMAN, which grew 19 percent, slowed sharply in February as stand-alone procedures fell even as concomitant adoption grew. Urology nearly flatlined at 1 percent growth due to problems in stone management and sacral neuromodulation. Management said the company lost more market share than expected and hospital capacity constraints are limiting WATCHMAN procedure volume.

Guidance The company cut its full year sales growth guidance from an expected 8 to 10 percent range down to 6.5 to 8 percent. They expect second quarter sales to grow only 5 to 7 percent year over year. The company now guides full year earnings per share to $3.34 to $3.41, still up 9 to 11 percent but well below prior expectations.

Severe negative reset. The report materially damaged the forward outlook and likely forces major downward revisions.
