Bull points
- it sounds like you're guiding third quarter gross margin to increase 150 to maybe 200 bps sequentially due to improvements in our mix in the IP optical business and a shift toward more software in the cloud and edge segments.
- The largest portion of our deferred revenue pipeline is associated with our maintenance and support contracts, and a large portion of those bookings tend to happen in Q4, indicating a setup for future revenue growth.
- We had an exceptional quarter, generating revenues of $221 million, an increase of 15% in the prior year, and above the top end of the guidance we gave during our Q1 earnings call.
Bear points
- Yeah, we definitely see the weakening U.S. dollar as a headwind from an OpEx perspective, impacting approximately a million dollars in the second quarter, with potential headwinds of roughly around $2 million a quarter ahead if current exchange rates hold.
- We expect gross margin to improve sequentially from Q2 to Q3 given the higher mix of software and less hardware, but compared year over year, we're still lower primarily due to the increased professional services that we're doing with some of these modernization programs.
- Most of the sort of weakening of the dollar occurred during the second quarter, so probably on OpEx, it was about a million dollars in there. Clearly, as you look forward for the rest of the year, we do see headwinds roughly around $2 million a quarter.
