Analyst · the Arista website following this call. I will now turn the call over to Mr. Curtis McKee, Director of Corporate and Investor Development. Sir, you may begin
Thanks, Jayshree, and good afternoon. This analysis of our Q4 and full year 2019 results and our guidance for Q1 2020 based on non-GAAP and excludes all non-cash stock-based compensation impacts, certain acquisition-related charges and other nonrecurring items. A full reconciliation of selected GAAP to non-GAAP results is provided in our earnings release. Total revenues in Q4 were $552.5 million, down 7% year-over-year and above the midpoint of our guidance of $540 million to $560 million. Service revenues represented approximately 19% of total revenue up from 15.2% last quarter, reflecting typical fourth quarter service renewal seasonality in conjunction with the lower product revenue number. International revenues for the quarter came in at $137.7 million or 25% of total revenue, up from 19% in the third quarter. Looking to the year, international revenues accounted for 24% of total revenue, down from 28% in the prior year. This shift in geographical mix for the year was largely driven by heavier U.S. deployments by our cloud titan customers. Overall gross margin in Q4 was 65.2% above the upper end of our guidance range of 63% to 65%, and up from 64.4% last quarter. This reflected a lighter cloud titan contribution in the period combined with good performance from our enterprise and financial verticals. Operating expenses for the quarter were $154.3 million or 27.9% of revenue, down from last quarter at $163 million. R&D spending came in at $96.2 million or 17.4% of revenue, down from $105.3 million last quarter. This decline largely reflected lower engineering and prototype costs in the period. Sales and marketing expense was $46.4 million or 8.4% of revenue with increased headcount somewhat offset by reductions in other sales costs. Our G&A costs were consistent with last quarter at approximately $12 million or 2.1% of revenue. Our operating income for the quarter was $205.8 million or 37.3% of revenue. Other income and expense for the quarter was a favorable $11.2 million and our effective tax rate was approximately 15.5%. This lower tax rate reflected the release of some uncertain tax position related reserves following final agreement with the relevant tax authorities. Please note, however, that we do expect to see some upward pressure on the effective tax rate over time. As various tax jurisdictions continue to modify their tax rules. This resulted in net income for the quarter of $183.4 million or 33.2% of revenue. Our diluted share number for the quarter was 80.26 million shares resulting in a diluted earnings per share number for the quarter of $2.29, up 1.8% from the prior year. Now turning to the balance sheet. Cash, cash equivalents and investments ended the quarter at approximately $2.7 billion. We repurchased $51.5 million of our common stock during the quarter at a weighted average price of $189 per share. This brings our total repurchases for the year to $266 million over three quarters. As a reminder, our Board of Directors has authorized a three-year $1 billion stock repurchase program commencing in Q2 2019. The program allows us to repurchase shares of our common stock opportunistically and is funded from operating cash flows. We generated $327 million of cash from operations in the fourth quarter affecting strong net income performance and a decrease in working capital requirements of approximately $115.4 million. DSOs came in at 65 days, up from 63 days in Q3, reflecting the timing of billings in the period. Inventory turns were 2.9 times, down from 3.1% last quarter. Inventory increased to $244 million in the quarter, up from $240 million in the prior period. Our total deferred revenue balance was $575 million, up from $529 million in Q3. As a reminder, our deferred revenue balance is now almost exclusively services related with any significant product deferred revenue amounts having been recognized to the income statement in the first half of the year. As Jayshree mentioned, we had two greater than 10% customers in the year; Microsoft at 23% and Facebook at 16.6%. If you exclude the recognition of product deferred revenue referenced above Facebook would have represented approximately 12% of revenue for the year. Accounts payable days were 44 days, up from 31 days in Q3, reflecting the timing of inventory receipts and payments. Capital expenditures for the quarter were $2.4 million. Now turning to our outlook for the first quarter and beyond. While we're not in a position at this point to provide full year guidance, we wanted to reiterate the various puts and takes discussed on our last call. 2019 has been a challenging year for our cloud business with significant volatility and an overall muted demand picture. As we look forward to 2020, we believe this trend continues with demand from this part of the business being flat to down on a year-over-year basis. This trend combined with tough year-over-year revenue comparisons due to the recognition of $118 million of product deferred revenue in the first half of 2019 will likely result in a meaningful decline in cloud revenue for 2020. Enterprise and financials are expected to grow healthily but are not yet large enough to fully offset the expected revenue decline from cloud, service provider and specialty cloud will likely remain sluggish for the year. On the gross margin front, we would reiterate our overall gross margin outlook of 63% to 65%, the customer mix being the key driver. Focusing specifically on Q1, we expect to trend lower in this range, given a lighter revenue number and a typical first quarter weighting towards cloud. We'll continue to manage investments in the business carefully with target growth in sales and R&D headcount, balancing the need to expand our market coverage with prudent financial management. We announced the acquisition of Big Switch Networks earlier today. This represents an immaterial transaction, who brings us some additional software capabilities and a strong engineering talent pool. From a financial perspective, this is a software subscription business with upfront license revenue recognition and a fair amount of services deferred revenue. We're beginning the business and accounting integration now and the acquisition will be recorded in our financials for the first quarter. We have included a small revenue contribution and two months of expenses for Big Switch in our guidance for the first quarter. We will provide additional clarity on the go-forward income statement impacts, once we've completed the purchase accounting analysis. Finally our guidance for Q1 does not reflect any impact from the ongoing coronavirus outbreak in China. While we do not have a significant direct manufacturing footprint in China, there may be some indirect supply chain impacts. We will look to monitor and attempt to mitigate these 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 $522 million to $532 million, gross margin of approximately 63%, operating margins of approximately 34%. And our effective tax rate is expected to be approximately 21% per diluted shares of approximately 80.5 million shares. I will now turn the call back to Curtis. Curtis?
