Network application delivery and security specialist F5 Networks (NASDAQ:FFIV) will be reporting earnings tomorrow after market close. Here's what to expect.
Last quarter F5 Networks reported revenues of $702.6 million, up 4.17% year on year, in line with analyst expectations. It was a mixed quarter for the company, with revenue exceeding expectations, albeit by a small magnitude. Gross margin also improved. On the other hand, its underwhelming revenue guidance for the next quarter was disappointing (although next quarter's EPS guidance was in-line).
Is F5 Networks buy or sell heading into the earnings? Read our full analysis here, it's free.
This quarter analysts are expecting F5 Networks's revenue to grow 0.32% year on year to $702.3 million, slowing down from the 2.64% year-over-year increase in revenue the company had recorded in the same quarter last year. Adjusted earnings are expected to come in at $3.21 per share.
Majority of analysts covering the company have reconfirmed their estimates over the last thirty days, suggesting they are expecting the business to stay the course heading into the earnings. The company only missed Wall St's revenue estimates once over the last two years, and has on average exceeded top line expectations by 0.76%.
With F5 Networks being the first among its peers to report earnings this season, we don't have anywhere else to look at to get a hint at how this quarter will unravel for software stocks, but the segment has been facing declining investor sentiment following the fears around raising interest rates, with the stocks down on average 3.3% over the last month. F5 Networks is down 7.7% during the same time, and is heading into the earnings with an analyst price target of $168.15, compared to share price of $146.31.
One way to find opportunities in the market is to watch for generational shifts in the economy. Almost every company is slowly finding itself becoming a technology company and facing cybersecurity risks and as a result, the demand for cloud-native cybersecurity is skyrocketing. This company is leading a massive technological shift in the industry and with revenue growth of 70% year on year and best-in-class SaaS metrics it should definitely be on your radar.

F5 (FFIV 1.13%) stock gained in Wednesday's daily trading. The company's share price ended the day up more than 2%, according to data from S&P Global Market Intelligence.
After the market closed Tuesday, F5 published results for the fourth quarter of its 2023 fiscal year -- which ended Sept. 30. Sales and earnings performance for the period came in ahead of market expectations and helped to send the software specialist's share price higher.Â
Why are investors excited about F5's Q4 results?
F5 reported non-GAAP (adjusted) earnings per share of $3.50 on sales of $706.97 million. For comparison, the average analyst estimate had called for per-share earnings of $3.21 on sales of roughly $702.25 million. F5's sales were up roughly 1% year over year in the quarter, and its adjusted earnings per share were up roughly 33.6% compared to the prior-year period.Â
The company delivered a significant performance beat on both the top and bottom lines. Management's forward guidance also seems to be pleasing investors.Â
What comes next for F5 stock?
For its next fiscal year, F5 is guiding for sales to come in somewhere between flat and a low-single-digit decline. While that might not sound like a particularly exciting projection, the company is facing caution from customers amid macroeconomic uncertainty -- and its earnings and stock buyback forecasts are more encouraging.Â
F5 expects to grow adjusted earnings per share somewhere between 5% and 7% on an annual basis. The company also plans to commit at least 50% of its annual free cash flow to repurchasing shares. As the company buys back stock, that will reduce its total number of shares outstanding. In turn, that should create positive catalysts for earnings per share in subsequent years. It may also signal that the company believes that its stock is undervalued at current prices.Â
