For Q4 'twenty four, our results were in line with our guidance for both GAAP and non GAAP expenses, and our spending was relatively flat quarter over quarter. Non GAAP operating expenses were $98,300,000 for Q4, which is within our guided range of $95,000,000 to $110,000,000 And our total operating expenses on a GAAP basis were $124,200,000 which were also within the $120,000,000 to $140,000,000 range previously provided. For context, our GAAP operating expenses included approximately $25,900,000 of non cash expenses, primarily driven by the 23,900,000 of stock based compensation. For the full year 2024, our non GAAP operating expenses were $380,600,000 a 22% increase year over year. And our GAAP operating expenses for the full year were $509,700,000 a 14% increase year over year, primarily due to the investments we have made in people related spend, materials and non recurring engineering costs to support our current phase of aircraft development and testing, as well as our manufacturing scale up.
