Poshmark said it was spending more on marketing, directing funds toward TV advertisements and partnering with social media influencers to counter the impact of Apple's privacy changes. The increased expenditure, however, has led Poshmark to report a third-quarter loss of 9 cents per share, bigger than analysts' estimates of a loss of 7 cents per share, according to IBES data from Refinitiv. The company's downbeat results come amid intensifying competition among resale platforms looking to attract shoppers turning to secondhand apparel as traditional retailers face shortages of new clothing. ThredUp, which went public in March, forecast fourth-quarter revenue above estimates and said it was lowering prices to attract customers at a time clothing retailers have been increasing rates to counter surging costs and supply bottlenecks.
