In the latest period of Q1'26, Archer Aviation (ACHR)'s gross margin reached 18.75%, marking a positive shift from 0% in Q4'25, while the operating margin improved to -159.13% from -781.33%, and the net profit margin narrowed to -136.06% from -629.67%, indicating ongoing but less severe losses across profitability metrics. Over the timeframe from Q2'23 to Q1'26, the chart shows no data available for earlier quarters, with profitability metrics only emerging in Q4'25 amid significant negative values driven by high operational costs in this pre-revenue stage of the eVTOL developer. From Q4'25 to Q1'26, all margins exhibit a stabilizing trend with gross margin turning positive and loss margins contracting substantially, suggesting potential progress in cost management and gross profitability, though net and operating margins remain deeply negative due to R&D and scaling expenses. This line chart highlights volatility in early data points but an inflection toward improvement in the most recent periods.
