Fortinet stock gains 2.57 percent near its 52-week high

Fortinet stock stood at USD 178.74 on Nasdaq on September 23, 2026 at 4:00 p.m. ET, up 2.57 percent and 0.34 percent below its 52-week high of USD 179.35. The move follows a second quarter in which revenue rose 26 percent to USD 2.05 billion.

Revenue and billings accelerate

According to Zacks, Fortinet's second-quarter 2026 billings increased 33 percent year over year to USD 2.37 billion. Product revenue rose 52 percent to USD 773 million, giving the quarter a sharper product-led profile than the 26 percent total revenue increase.

The same report puts non-GAAP operating margin at a second-quarter record of 38 percent and free cash flow at USD 966 million, more than triple the prior-year figure. Non-GAAP EPS rose 41 percent to USD 0.90, a comparison that links the earnings result to the revenue expansion rather than to price momentum alone.

Guidance sets the next test

Fortinet raised its full-year 2026 revenue outlook to USD 8.02 billion to USD 8.18 billion and its non-GAAP EPS guidance to USD 3.41 to USD 3.47, according to Zacks. For investors, the key question is whether billings growth can keep supporting a valuation that has already carried the stock close to its yearly peak.

Analyst target remains higher

TD Cowen reiterated a Buy rating and a USD 215 price target on September 16, 2026, as Investing.com reported. The firm projected second-half revenue growth of 18 percent, two percentage points above consensus, and billings growth of 23 percent.

Stock stays near yearly peak

Fortinet stock was USD 178.74 on Nasdaq on September 23, 2026, with a market capitalization of USD 131.14 billion. Its 52-week range was USD 73.55 to USD 179.35, leaving the share price 0.34 percent below the upper boundary and making the latest revenue and billings trajectory central to the valuation debate.
