The latest data point for Q1'26 shows total operating expenses at $0, with R&D expenses remaining at $0 and SG&A expenses also reported as no data, indicating a complete absence of reported figures for this period. Over the period from Q2'23 to Q4'25, SG&A expenses—the sole contributor to operating expenses given R&D's consistent $0 values—exhibited volatility with an overall upward trend, rising from $568M in Q2'23 to a peak of $749M in Q4'25, including notable increases in Q4'23 ($731M) and Q4'25 amid periodic declines such as in Q3'24 ($536M). This pattern suggests fluctuating administrative and operational costs for MCD, potentially driven by seasonal factors or strategic investments, while the stacked bar chart highlights SG&A's dominance in the total expense profile.
