Shares of A10 Networks declined 3.8% following earnings, as the market reacted to signs of deceleration in key growth metrics and management’s cautious tone regarding the durability of recent large enterprise deals. Despite reporting double-digit revenue growth, investor concern appeared focused on the sustainability of momentum amid mention of timing-driven benefits and significant customer concentration this quarter.

• Revenue grew 13.4% year-over-year to $75 million, with product revenue up 22.3%.
• A single customer related to an AI infrastructure build-out accounted for 5% of total revenue this quarter, highlighting heightened customer concentration risk and suggesting growth was partly timing-driven.
• Management cited the benefit from large orders in the enterprise segment, but characterized this as related to timing, implying growth rates may not be sustainable.
• Trailing 12-month adjusted EBITDA margin was 29.7%, consistent with the company’s profitability targets and past performance.
• Commentary emphasized alignment with longer-term AI demand but stopped short of reiterating a clear acceleration or upward revision to outlook.
