Fastly shares soar 62% one year after InvestingPro’s undervalued rating

InvestingPro’s Fair Value model flagged Fastly (FSLY) as undervalued in Nov 2024 when the stock traded at $7.18; the shares have since risen 62.4% to $11.66. At the time Fastly reported $540.87m revenue, EBITDA of -$105.72m and EPS of -$1.09; more recent Q1 and Q3 2025 results showed revenue of $591.99m (up 9.5% YoY) and EBITDA improvement of 24.4% to -$79.89m. The model previously estimated intrinsic value at $10.60 and now places fair value at $13.97 (implying ~17.6% upside), while analysts including Oppenheimer have issued price targets and the company plans a move from NYSE to Nasdaq, supporting renewed investor interest.

Analysis

Market structure: Fastly (FSLY) and other edge/AI infrastructure specialists (e.g., SMCI) are the primary beneficiaries as AI workloads shift latency-sensitive workloads to the edge; security revenue expansion also creates higher gross margins if upsells continue (17% non‑top10 customer growth signals diversification). Incumbent legacy CDNs (Akamai) and pure-play ad-tech (APP) face pricing pressure and slower growth; increased tech flows could compress credit spreads for higher‑growth names and raise equity volatility, lifting short‑dated IV by 20–40% around earnings.

Risk assessment: Tail risks include a major security incident, a large customer churn (top‑5 customer concentration), or an AI demand slowdown that could revert EBITDA trajectory—each could trigger >30% downside within days. Near term (days–weeks) focus is on Nasdaq transfer and quarterly prints; medium term (3–12 months) the path to sustainable EBITDA improvement matters; long term (12–36 months) depends on edge adoption and capex intensity. Hidden dependencies: wholesale interconnect contracts and peering costs, and potential capital spending that can re‑lever the balance sheet.

Trade implications: Direct play: establish a controlled long in FSLY via position sizing + options to cap risk (see decisions). Consider a pair trade long FSLY vs short AKAM to isolate “edge vs legacy” exposure for 6–12 months. Options: buy 6–9 month call spreads to play upside while selling OTM puts to accumulate below $10; avoid buying into earnings IV spikes. Rotate 1–2% portfolio weight from ad‑tech (APP) into AI infra (SMCI, FSLY) over 30–90 days.

Contrarian angles: Consensus underestimates recurring security revenue and non‑top10 customer momentum; fair value moved from $10.60 to ~$13.97 suggesting still partially priced upside. The Feb 2025 35% drawdown shows knee‑jerk volatility, not necessarily structural failure — similar patterns occurred with NET during monetization inflection. Unintended consequences: Nasdaq listing increases passive/ETF eligibility which can bring one‑off selling and higher short interest; be ready for 15–25% intraday moves around listed catalysts.

Key Decisions for Investors

• Establish a 2–3% long position in FSLY if price ≤ $14 (average cost target $11–14). Set a tactical target of $18 within 6–12 months and a hard stop‑loss at 20% below entry; trim 50% at +30% realized gain.
• If you prefer options, buy a 6–9 month FSLY call spread (e.g., long 12 / short 20 strikes) sized for 2% portfolio risk, and simultaneously sell 90‑day $10 OTM puts up to 1% notional to lower cost if willing to own at $10.
• Implement a pair trade: long $1mm FSLY vs short $1mm AKAM for 6–12 months to play edge adoption; exit if the spread narrows/widens by 15% or if FSLY misses two consecutive quarters of revenue guidance.
• Reallocate 1–2% from overbought ad‑tech/consumer cyclicals (e.g., APP) into AI infrastructure names (SMCI, FSLY) over 30–90 days; monitor implied vol — only add if 30‑day IV <50% to avoid buying into volatility spikes.
