Our revised 2025 GAAP operating expense range is now $5,900,000,000 to $6,100,000,000 a $400,000,000 reduction at the midpoint from our previous guidance of $6,400,000,000 This updated guidance puts us on track to achieve the first $5,000,000,000 of our overall $6,000,000,000 reduction in annual GAAP expenses in two years. Our updated 2025 guidance includes $900,000,000 of non cash expenses from stock based compensation, depreciation and amortization. Excluding those non cash items, we now project a 2025 cash cost of approximately $5,100,000,000 at the midpoint of the range, a $400,000,000 reduction from our previous cash cost estimate of $5,500,000,000 The strong progress in cost reductions to date has been a company wide effort. While we continue to drive additional cost reductions in all areas, the largest source of future reductions will come from R and D, which represents over 60% of our cost base. On the next slide, I want to share our strategy to achieve our 2027 operating expense targets in more detail.
