Palo Alto sinks on big CyberArk buyout news

Palo Alto is reportedly nearing the end of negotiations to acquire CyberArk -- an Israel-based cybersecurity company specializing in identity management solutions. While that's probably not bad news for long-term investors, it's reasonable to expect that Palo Alto will wind up paying a premium to buy out CyberArk if a deal materializes. Given the potential for new stock to be issued in order to fund the deal, Palo Alto's share price could be seeing a pullback today due to concerns about stock dilution.

What's next for Palo Alto Networks?

For long-term investors, Palo Alto Networks buying CyberArk could actually be a beneficial development. The cybersecurity industry looks poised to see significant consolidation trends over the next decade, and the outlook on that front is connected to the increasingly important role that artificial intelligence (AI) will play in digital protections. While valuations for acquisitions will continue to be a meaningful concern for shareholders, Palo Alto making big buyout plays could significantly strengthen the company over the long haul.
