Why POST stock is down today

Post Holdings stock fell by 10.14% to $81.01 in early trading on Tuesday, driven by a disappointing earnings report and a revised outlook for fiscal year 2027. The company reported GAAP earnings per share of $1.29, missing estimates by $0.36, and revenue of $1.9 billion, which fell short of expectations by $130 million. Stifel also cut its price target for the stock following the company’s outlook for flat performance in FY27.

What Happened

Post Holdings released its third-quarter results for fiscal year 2026, with GAAP earnings per share of $1.29 and revenue of $1.9 billion. Both figures missed estimates. The company also narrowed its full-year 2026 outlook and provided details in a Form 8-K filing. Stifel analysts responded by lowering the stock’s price target, citing the flat FY27 outlook. The stock opened with a -4.4% gap down from the previous close and continued to fall through the morning session, reaching a low of $78.95 before closing the session at $81.01.
