Beauty retailer Elf Beauty is facing concerns over a potential slowdown as it reports earnings, with analysts predicting the first decline in eight quarters. Despite beating estimates for Q4, the company's annual sales and profit projections fell below expectations, leading to a drop in share prices. Elf Beauty's stock initially plunged 12% after the earnings recap revealed a disappointing FY outlook. However, the stock recovered slightly, ending the day up 21%. The company posted its first $1 billion year, but shares fell due to weaker-than-expected guidance, causing fluctuations in after-hours trading.
