Analyst · the Arista website following this call. I will now turn the call over to Mr. Charles Yager, Director of Product and Investor Advocacy. Sir, you may begin
Thanks, Jayshree, and good afternoon. This analysis of our Q4 and full year 2020 results and our guidance for Q1 2021 is based on non-GAAP and excludes all non-cash stock-based compensation impacts, certain acquisition-related charges and other non-recurring items. A full reconciliation of our selected GAAP to non-GAAP results is provided in our earnings release. Total revenues in Q4 were $648.5 million, up 17.4% year-over-year and well above the upper end of our guidance of $615 million to $635 million. While we continue to strive for improvements on the supply chain front, shipments remained somewhat constrained in the quarter, with some COVID second and third wave-related disruptions. Service and software support renewals represented approximately 20% of total revenue, down slightly from 21% last quarter. International revenues for the quarter came in at $165.7 million, or 26% of total revenue, up from 25% in the third quarter. While the shift in geographical mix on a quarter-over-quarter and year-over-year basis is largely due to the location of deployments by our third - by our cloud titan customers, we did see some incremental improvement in our in region businesses this quarter. Overall gross margins in Q4 were a healthy 65%. At the upper end of our guidance of approximately 63% to 65%, reflecting a heavier mix of shipments to our enterprise and financial customers in the period. Operating expenses for the quarter were $178.1 million, or 27.5% of revenue, up from last quarter at $159.4 million. We continue to increase operating expense investments during the quarter as our top line performance for the year continued to improve. R&D spending came in at $110.2 million, or 17% of revenue, up from $106.1 million last quarter. This reflected increased employee costs, somewhat offset by lower new product introduction spending in the period. Sales and marketing expense was $54.9 million, or 8.5% of revenue, up from $43.1 million last quarter with increased variable compensation and other headcount-related charges. As a reminder, we continue to benefit from lower COVID-related travel and marketing expenses. Our G&A costs came in at $13 million, or 2% of revenue of revenue, up from last quarter at approximately $10.2 million, reflecting normal fourth quarter compliance-related activities. Our operating income for the quarter was $243.5 million, or 37.6% of revenue. Other income and expense for the quarter was a favorable $1.4 million, and our effective tax rate was approximately 19.3%. Other income and expense included $2.5 million of interest income, offset by some unfavorable FX amounts. The favorable tax rate included the release of some tax reserves, for which the statute of limitations expired in the period. This was a one-time effect, and the rate will likely return to a more structural rate of 21.9% in future periods. Overall, this resulted in net income for the quarter of $197.7 million or 30.5% of revenue. Our diluted share number was 79.3 million shares, resulting in a diluted earnings per share number for the quarter of $2.49, up approximately 9% from the prior year. Now turning to the balance sheet. Cash, cash equivalents and investments ended the year at approximately $2.87 billion. To recap on our uses of cash for the year, we generated $735 million of cash from operations and returned approximately $395 million, or 54%, of this to shareholders in the form of share repurchases. In addition, we used approximately $227 million, or 31%, to fund cash consideration for two acquisitions, which closed during the year, retaining the balance of approximately $113 million in the business. To date, we have repurchased $661 million, or 3.2 million shares, against our Board authorization to repurchase $1 billion worth of shares over three years commencing in Q2 2019. We will continue to execute opportunistically against the remaining mandate. Turning to the operational cash performance for the fourth quarter. We generated $186.9 million of cash from operations in the period, reflecting solid net income performance and continued investments in working capital. DSOs came in at 55 days, up from 46 days in Q3, reflecting the linearity of billings in the period. Inventory turns were 1.8 times, down from 2 times last quarter. Inventory increased to $480 million in the quarter, up from $438 million in the prior period, as we continue to buffer certain components and products. Our total deferred revenue balance was $651 million, up from $562 million in Q3. This increase largely reflected typical fourth quarter service renewal activity and a small amount of deferred product revenue related to new product deployments. The level of services deferred revenue is directly linked to the timing and term of service renewals, which can vary on a quarter-over-quarter basis. Accounts payable days were 54 days, down from 70 days in Q3, reflecting the timing of inventory receipts and payments. Capital expenditures for the quarter were $3.2 million. Now turning to our outlook for the first quarter and beyond. We saw good diversification of the business in fiscal 2020, with expected declines in cloud titan revenue, somewhat offset by growth in our other market sectors. Looking to 2021, we expect continued growth with our enterprise and provider customers, combined with the solid cloud titan contribution. From a product perspective, we expect strength in adjacencies and software and services continue to make these areas a more meaningful contributor to the business over time. We believe the combination of these trends, combined with favorable year-over-year comparatives allowed for a top line growth rate for the year, which is in line with annual consensus growth rates of 14% to 15%. You should also note that our second half 2020 top line recovery will likely result in some deceleration in quarterly year-over-year growth rates as we move through 2021. On the gross margin front, we will continue to reiterate our overall gross margin outlook of 63% to 65% with customer mix remaining the key driver. Turning to spending and investments. We remain committed to making go forward results based investments in the business. This includes continued go-to-market expansion to support enterprise and campus growth and investments in R&D to support innovation across the business. Finally, our outlook discussion above and our guidance for Q1, reflects our current understanding of COVID-19 and its impact on our business and supply chain. This is, however, an inherently uncertain situation, and we will need to continue to monitor and attempt to mitigate new challenges as the situation unfolds. With all of this as a backdrop, our guidance for the first quarter, which is based on non-GAAP results and excludes any non-cash stock-based compensation impacts and other non-recurring items is as follows, revenues of approximately $630 million to $650 million, gross margin 63% to 65%, operating margin of approximately 37%. Effective tax rate is expected to be approximately 21.9% with diluted shares of approximately 80 million shares. I will now turn the call back to Charles. Charles?
