Without specific numerical data for Q2 2020 to Q1 2021, a detailed analysis is impossible.  The report mentions working capital efficiency, cost efficiency (including ratio of retained earnings to revenue and SG&A expense ratio), and investment efficiency (including retained earnings on assets and earnings per share). However, the absence of quantitative information prevents any conclusions.
