Valuation (price ÷ last four quarters, through Jun 30, 2026) (TENB)

P/E 686.1x · P/S 4.4x · P/FCF 17.5x · P/B 23.3x · FCF yield 5.72% · Earnings yield 0.15% · Buyback yield (TTM) 7.62%

Insider sales (SEC Form 4, open-market, last ~7 months) (TENB)

1 of 3 under a Rule 10b5-1 trading plan (scheduled in advance). Unplanned sales were timed by the insider.

% of holdings sold = shares sold ÷ (shares sold + all holdings the insider reported on that Form 4, direct and through trusts).

Insider type follows Cohen, Malloy & Pomorski (Journal of Finance, 2012). An insider who traded the stock in the same calendar month in each of the past three years is a routine trader; one who traded in each of those years without such a pattern is an opportunistic trader. In their study, trades by opportunistic insiders predicted future returns and trades by routine insiders did not. Counts open-market purchases and sales only (SEC Form 4 codes P and S) by that insider in that company. Not investment advice.

Insider purchases (SEC Form 4, open-market, last ~7 months) (TENB)

1 purchase, $258K. Private placements, offerings, dividend reinvestment and employee stock purchase plan buys are excluded.
