Fastly Jumps 19% as Security Growth Powers a Q2 Beat and Raised Outlook

Fastly (FSLY) surged nearly 19% Monday to about $27.43, after the edge-cloud company crushed Q2 2026 expectations and lifted its full-year guidance. Booming demand for its security products drove the quarter, and investors quickly rewarded the results, extending one of the market’s strongest software turnarounds.

Key Points

• The beat: FSLY posted Q2 2026 revenue of $183.3 million, up about 23% year over year and a company record, topping its own guidance.
• The bottom line: Adjusted EPS landed at $0.15, more than double the $0.07 consensus estimate.
• The driver: Security led the way, with “other products” jumping roughly 69%, reshaping Fastly from a pure CDN into a broader security-and-edge platform.
• The margins: Gross margin reached about 65.8%.
• The guidance: Management raised its full-year 2026 outlook.
• The Street: RBC Capital lifted its target to $28 from $22 (Sector Perform), while DA Davidson stayed Neutral.
• The run: FSLY is now up roughly 169% year-to-date and about 292% over the past year.

Security Growth Reframes the Story

Because investors long viewed Fastly as a content-delivery network fighting for commoditized traffic, the quarter’s security momentum matters enormously. This time, the company’s security suite — spanning next-gen web application firewall, bot management, DDoS protection, and API defense — powered the upside, and its faster-growing “other products” category jumped about 69%. Consequently, FSLY is steadily transforming into a higher-value platform rather than a pure CDN, and that shift helps justify a premium multiple. Moreover, management paired the revenue strength with a healthy gross margin near 65.8%, which signals that the growth isn’t coming at the expense of unit economics.

The Numbers Beat Across the Board

Fastly didn’t just edge past estimates — it cleared them decisively. Revenue rose roughly 23% year over year to a record $183.3 million, while adjusted EPS of $0.15 more than doubled the $0.07 analysts expected. In addition, the company raised its full-year 2026 outlook, and that guidance hike gave the market confidence that the momentum can continue into the back half of the year. As a result, several analysts moved quickly: RBC Capital raised its price target to $28 from $22, and other firms nudged their targets higher as well.

Valuation and Risks Temper the Bull Case

Although the results impressed, investors shouldn’t ignore the caveats. First, FSLY remains unprofitable on a GAAP basis, posting a Q2 net loss near $15.6 million and a trailing EPS of -$0.53. Second, the stock now trades at a rich forward P/E around 60 after its enormous run, so expectations sit high. Furthermore, some analysts continue to flag revenue concentration among a handful of large customers, which introduces risk if any major account pulls back. For that reason, several firms — including RBC and DA Davidson — maintained cautious Neutral or Sector Perform ratings even while raising targets.

What to Watch Next

Looking ahead, investors should first track whether Fastly sustains its security growth rate, since that segment now anchors the bull thesis. Next, watch for progress toward consistent GAAP profitability, because the current valuation increasingly demands it. Finally, keep an eye on customer diversification and net revenue retention, as broader adoption would ease concentration worries. Ultimately, if Fastly (FSLY) keeps converting security demand into record revenue and raised guidance, today’s jump could mark another step in a longer re-rating rather than a peak.
