Analyst · the Arista website following this call. I will now turn the call over to Mr. Charles Yager, Director of Product & Investor Advocacy. Sir, you may begin
Thanks Jayshree and good afternoon. This analysis of our Q1 results and our guidance for Q2 2019 is based on non-GAAP and excludes our 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 Q1 were $595.4 million, up 26% year-over-year and above the mid-point of our guidance of $588 million to $598 million. Service revenues were strong representing approximately 15.1% of revenue, down from 15.5% last quarter reflecting a healthy level of renewals for the period. International revenues for the quarter came in at $156 million, or 26% of total revenue, up from 24% in the prior quarter. Overall, gross margin in Q1 was 64.5% above the mid-point of our guidance range of 63% to 65% and up from 64.1% last quarter. Gross margin in the period benefited from healthy enterprise and service contributions combined with a continued focus on cost optimization. Operating expenses for the quarter were $160.7 million, essentially flat to last quarter on an absolute dollar and percentage of revenue basis. R&D spending came in at $106.5 million, or 17.9% of revenue, up slightly from last quarter. We continue to see significant new products related NRE and prototype spending in the period. Sales and marketing expense was $43.6 million, or 7.3% of revenue. Again essentially flat to last quarter with increased headcount offset by some reductions in other sales costs. Our G&A costs were $10.5 million or 1.8% of revenue, down slightly from last quarter. Our operating income for the quarter was $223.6 million, or 37.5% of revenue. Other income and expense for the quarter was a favorable $11.2 million and our effective tax rate was lower at approximately 20%. The lower tax rate primarily reflected the finalization of certain tax reform positions based on updated IRS in the regulatory guidance. This resulted in net income for the quarter of $187.7 million, or 31.5%. Our diluted share number for the quarter is 81.2 million shares resulting in a diluted earnings per share number for the quarter of $2.31, up 39.2% from the prior year. Now turning to the balance sheet. Cash, cash equivalents and investments ended the quarter at approximately $2.2 billion. We generated $170 million of cash from operations in the quarter, reflecting strong net income performance offset by new product rated working capital increases and a reduction in overall deferred revenue amounts. DSOs came in at 41 days, down from 51 days in Q4, reflecting strong collections activity of the timing of billings in the quarter. Inventory turns were 2.5 times, down from 3.3 times last quarter. Inventory increased to $347.2 million in the quarter, up from $264.6 million in the prior period. This primarily reflects increases in raw materials and finished goods as we ramp the supply chain for new products. Our total deferred revenue balance was $536.5 million, down from $587.2 million in Q4. Our product deferred revenue balance decreased by approximately $80 million in the quarter affecting customer acceptances of new features. This trend is consistent for 2018 and we also had a significant reduction of product deferred revenue in the first half of the year. Accounts payable days were 38 days down from 40 days in Q4, reflecting the timing of inventory receipts and payments. Capital expenditures for the quarter were $5.2 million. In addition, we announced today that our board of directors has authorized a three year $1 billion stock repurchase program. This allows us to repurchase shares of our common stock opportunistically and will be funded from working capital. Now, turning to our outlook for the second quarter and beyond. As we look forward, we believe that we remain well positioned with our key cloud customers and our focus on expanding our presence in the enterprise and other verticals, especially as we bring new products to market in the second half of the year. While we executed well across all key financial metrics in the March quarter, we saw some shortfall in demand at the back end of the period primarily from our service provider and cloud verticals. Our second quarter guidance assumes this trend continues through the June quarter and we are managing the business on the assumption there maybe some impact for the full year. On the gross margin front, we would reiterate our overall gross margin outlook of 63% to 65% with customer mix being the key driver and indicating towards the upper end of the range for Q2 2019. We continue to invest in the expansion of the business including the addition of sales headcount and resources. We believe that with reasonable top-line growth, we continue to maintain operating margins at or above the previously discussed 35% range. With this as a backdrop, our guidance of the second quarter, which is based on non-GAAP results and excludes our non-cash stock-based compensation impacts and other non-recurring items is as follows: revenues of approximately $600 to $610 million, gross margin of approximately 64% to 65%, operating margin of approximately 36%. Our effective tax rate is expected to be approximately 21% with diluted shares of approximately 81.7 million. I will now turn the call back to Charles. Charles?
