Comparison of the three and nine months ended September 30, 2023 and October 1, 2022
Revenue
In the three months ended September 30, 2023, revenue increased by $80 million, or 18%, compared to the three months ended October 1, 2022. This increase in revenue was primarily due to a combination of volume and ASP growth in our EyeQ chip related revenue.
In the nine months ended September 30, 2023, revenue increased by $138 million, or 11%, compared to the nine months ended October 1, 2022. This increase was primarily due to an increase of $123 million, or 10%, in EyeQ® and SuperVision sales, attributable to an 8% increase in volume and a 2% increase in Average System Price which is calculated as the sum of revenue related to EyeQ® and SuperVision systems, divided by the number of systems delivered.
Cost of Revenue
In the three months ended September 30, 2023, our cost of revenue increased by $25 million, or 11% compared to the three months ended October 1, 2022. This increase was primarily due to an increase of $40 million in manufacturing costs related to increased sales of our EyeQ® and also the rise in the cost of our EyeQ® SoCs due to the global semiconductor shortage and inflationary pressures partially offset by a decrease of $21 million in amortization of intangible assets.
In the nine months ended September 30, 2023, our cost of revenue increased by $57 million, or 8%, compared to the nine months ended October 1, 2022. This increase was primarily due to an increase of $92 million in manufacturing costs relating primarily to increased sales of our EyeQ® SoC and our sales of SuperVision™ systems, as well as to a rise in the cost of our EyeQ® SoCs, partially offset by a decrease of $44 million in amortization expenses.
Gross Profit and margin
In the three months ended September 30 2023, our gross profit increased by $55 million, or 25% compared to the three months ended October 1, 2022.
In the nine months ended September 30 2023, our gross profit increased by $81 million, or 13%, compared to the nine months ended October 1, 2022.
The gross profit increase in both periods was mainly driven by the increase in revenue from our EyeQ® SoC sales, as well as the sales of our SuperVision™ solution and by the the decrease in Amortization charges related to fully amortized intangibles of Moovit’s acquisition.
Our gross margin has increased by 3 percentage points to 51% in the three months ended September 30, 2023 compared to 48% in the three months ended October 1, 2022. Our gross margin has increased by 1 percentage point to 49% in the nine months ended September 30, 2023 compared to 48% in the nine months ended October 1, 2022 . This is mainly due to the lower impact of the cost attributable to amortization of intangible assets as a percentage of revenue partly offset by the downward impact of the increased cost of our EyeQ® SoCs (which was passed through as a price increase to our customers on a zero-margin basis).
Research and Development Expenses, net
Research and development expenses, net, in the three months ended September 30, 2023, increased by $12 million, or 6%, compared to the three months ended October 1, 2022. This increase was primarily due to an increase of $11 million in payroll and related expenses, resulting from an increase in average research and development headcount of 383 employees, including an increase of $21 million in share-based compensation, mainly offset by the depreciation of the New Israeli Shekel against the USD which resulted in lower than expected payroll related expenses.
Research and development expenses, net, in the nine months ended September 30, 2023 increased by $99 million, or 18%, compared to the nine months ended October 1, 2022. This increase was primarily due to an increase of $76 million in payroll and related expenses, resulting from an increase in average research and development headcount of 441 employees and an increase in payroll costs, including an increase of $57 million in share-based compensation. The remaining increase is mainly related to occupancy and related expenses associated with the lease of new office space in additional sites.
