Jun 09, 2026, 12:37 PM ET Summary Phathom Pharmaceuticals, Inc. is downgraded to Sell due to concerns over growth sustainability, competition, and terminal value assumptions. Q1 sequential revenue growth was flat, raising doubts about Voquezna's adoption beyond early specialists despite management's optimism for future cash generation. Competition from Sebela’s tegoprazan threatens Voquezna’s pricing power and market share, challenging PHAT’s ability to achieve mid-teens FCF margins.
