​Despite the gains, recently, on June 30, HSBC downgraded the stock from Hold to Reduce and raised the price target from $98 to $102. The firm noted that the rating change is based on valuation concerns rather than fundamentals. Analyst Bersey noted Fortinet trades at a 2026 P/E of 46.1x, in line with cybersecurity peers, despite a much slower 11.6% EPS growth rate. He noted that the mismatch makes the risk-reward unattractive at current levels. The firm also flagged a large-scale device security event as a near-term risk, potentially slowing product and billings momentum as customers scramble to assess exposure. Moreover, HSBC raised its target multiple to 31x from 30x, reflecting AI-led re-rating across the sector, but kept it well below the peer median of 46x.
