RSKD Q3 revenue surges 41% to $115.2M; raised guidance offset by gross margin decline from elevated chargebacks

What happened

Riskified reported Q3 revenue of $115.2M, up 41% year-over-year, prompting management to raise full-year 2026 guidance beyond the $376-384M range set after Q1. However, gross margin declined as new merchants brought elevated chargeback ratios, signaling that the growth is coming at the cost of underwriting profitability. This directly aligns with the bear scenario in the prior DeepValue report, which flagged that a CTB ratio above 42% and gross margin below 50% would pressure EBITDA below $28M. The revenue surge likely reflects strong merchant acquisition or expansion, but it exacerbates the concentration risk and chargeback expense sensitivity already noted, with top-5 merchants representing ~32% of revenue. The stock remains volatile around $5.06, and the market must now weigh the trade-off between top-line acceleration and margin deterioration.

Implication

The strong Q3 revenue and raised guidance validate demand, but the margin decline raises the probability of the bear scenario where adjusted EBITDA falls below $28M on gross margin under 50%. The prior trim level of $6.50 is now well above the current price, and the attractive entry of $4.60 may be retested if chargeback pressure persists into Q4. Investors should monitor next quarter's CTB ratio and gross margin; if CTB stays above 42% and margin fails to recover above 50%, the base case value of $6.20 is at risk. Multi-product adoption remains the key offset—if management can demonstrate a mix shift toward higher-margin products, the bull case of $8.50 becomes more plausible despite near-term pain. Given the concentration risk and unusual insider selling activity noted in the master report, caution is warranted; wait for Q4 results or a pullback toward $4.60 before considering a position.

Thesis delta

The previous thesis centered on margin stability and raised guidance, but Q3 results show a shift to aggressive revenue growth at the expense of gross margin due to elevated chargebacks. This increases the likelihood of the bear scenario, where EBITDA falls short of the $28M floor. The rating may need to be downgraded from POTENTIAL BUY to HOLD until there is evidence that margin erosion is temporary or offset by multi-product adoption.
