Foolish take
Portolan Capital's purchase of Cellebrite is notable to investors for a few reasons.
First, the firm essentially doubled down on Cellebrite, making it Portolan's 10th-largest holding of 119 stocks. This is a significant purchase for the fund.
Second, this doubling down occurred at an average share price of around $18, compared to $11 when Portolan first purchased the stock in 2024. To me, this signifies that the firm is comfortable "adding up" on one of its winning investments -- a promising sign for long-term Cellebrite holders.
Lastly, the firm's purchase is interesting, as Cellebrite appears to have many Rule Breaker-style qualities, in my opinion.
The No. 1 solution for digital forensic examiners, Cellebrite helps over 7,000 public safety, government, and enterprise customers sift through vast amounts of data and evidence to solve a wide range of cases.
Whether helping collect, review, safeguard, analyze, or investigate evidence, Cellebrite's platform is a one-stop shop for its justice-seeking customers. As the company incorporates artificial intelligence into its platform, potentially helping to make connections within and across cases, Cellebrite could become an even more powerful force for justice.
Trading at 32 times free cash flow, Cellebrite isn't cheap. However, growing sales by 23% over the last year as the leader in its good-for-the-world niche makes the company a fun buy in my eyes.
