Tenable reported second-quarter 2026 revenue of $268.5 million, up 8.6% year over year, with GAAP net income of $3.8 million versus a $14.7 million loss in the prior-year quarter. The company also issued higher full-year 2026 guidance, including revenue of $1.075 billion to $1.081 billion and non-GAAP diluted EPS of $1.95 to $2.00; independent coverage later linked Tenable’s September 15 share-price rise to Q2 momentum, including Tenable One representing 50% of new business.

Yes. On matched daily closes, TENB materially outperformed the Nasdaq Composite between September 14 and October 2, 2026. TENB gained 19.55% ($30.92 to $36.965), compared with a 3.87% gain for the Nasdaq Composite (26,186.41 to 27,198.92). The relative-performance difference was approximately 15.68 percentage points.
The underlying event is verified. Tenable’s July 29, 2026 Q2 release reported revenue of $268.5 million, up 8.6% year over year; GAAP net income of $3.8 million versus a $14.7 million loss; non-GAAP diluted EPS of $0.51 versus $0.34; and full-year revenue guidance of $1.075 billion to $1.081 billion with non-GAAP diluted EPS guidance of $1.95 to $2.00. Tenable’s subsequent Form 10-Q independently reports the same Q2 revenue and GAAP net-income figures. These results quantify an improved quarter, although the release does not by itself establish that the stock move was caused by the results.
The price evidence supports the narrow relative-strength question. The first observed session, September 14, is used as the baseline close and October 2 as the endpoint; both instruments have 15 matched daily observations in the retrieved window. The calculation is: TENB (36.965 / 30.92 - 1) × 100 = 19.55%; Nasdaq Composite (27,198.9203 / 26,186.4133 - 1) × 100 = 3.87%; relative difference 19.55% - 3.87% = 15.68 percentage points.
Independent coverage published September 15 reported that TENB closed at $35.08, up 16.5%, and associated the move with Q2 momentum, including Tenable One representing 50% of new business and net dollar expansion of 106%. That supports the existence of a contemporaneous catalyst narrative, but it is attribution from a secondary source, not proof of causation.
The result answers relative performance, not causality or future returns. The Q2 release was published July 29, well before the September 14 baseline, so the measured interval captures post-catalyst persistence rather than the immediate earnings reaction. The retrieved evidence does not include a formal event study, peer basket, factor decomposition, short-interest data, institutional flows, options positioning, or a verified record of the market’s prior consensus estimates. Consequently, the data show that TENB outperformed during the specified window, but they do not isolate how much of that excess return came from Q2 results, Tenable-specific developments, cybersecurity-sector factors, or other information.
The July 29, 2026 earnings release reported Q2 revenue of $268.5 million, 8.6% year-over-year growth, GAAP net income of $3.8 million versus a $14.7 million loss, and full-year 2026 revenue guidance of $1.075 billion to $1.081 billion and non-GAAP diluted EPS guidance of $1.95 to $2.00.
U.S. Securities and Exchange Commission, Tenable Exhibit 99.1The filing reports Q2 2026 revenue of $268.508 million and net income of $3.805 million, compared with Q2 2025 revenue of $247.295 million and a net loss of $14.706 million.
U.S. Securities and Exchange Commission, Tenable Form 10-QTENB rose from $30.92 on September 14 to $36.965 on October 2, 2026: +19.55%. The Nasdaq Composite rose from 26,186.4133 to 27,198.9203: +3.87%. TENB’s excess return was approximately 15.68 percentage points.
Polygon historical daily bars via SentimentorZacks reported that TENB ended September 15 at $35.08, up 16.5%, and cited Tenable One representing 50% of new business and net dollar expansion of 106% as Q2 momentum indicators.
Zacks Investment ResearchTENB closed at $35.08 on September 14, $38.09 on September 15, then declined to $33.49 on September 26 before ending at $36.965 on October 2. The stock retained a positive full-window return, but the intervening pullback weakens any claim of uninterrupted post-catalyst momentum.
Polygon historical daily bars via SentimentorZacks noted that TENB had lost 21.5% over the preceding four weeks and that consensus EPS estimates had been revised marginally lower over the prior 30 days. It also described the cited outlook as conditional rather than proof of future gains.
Zacks Investment ResearchThe Nasdaq Composite gained 3.87% over the matched window. The comparison establishes relative outperformance, not an absolute-market-neutral return or company-specific causation.
Polygon historical daily bars via SentimentorThe issuer says it exceeded expectations, but a verified estimate set is needed to independently quantify the surprise relative to consensus rather than relying on management’s wording.
The retrieved evidence lacks an event-study decomposition, matched cybersecurity peer basket, factor model, order-flow record, institutional-flow data, or options-positioning data that could separate the earnings catalyst from sector and market effects.
The Nasdaq Composite is a broad benchmark, but the question of cybersecurity-stock relative strength would require a defined, independently sourced peer basket and matched-period calculations.
Question tested: From the September 14, 2026 close through October 2, 2026 close, did TENB outperform the Nasdaq Composite after the Q2-results catalyst, using matched daily closing prices?
The narrow question is supported: TENB gained 19.55% from the September 14, 2026 close to the October 2 close, versus 3.87% for the Nasdaq Composite, an excess return of about 15.68 percentage points. The Q2 results and higher full-year outlook are verified and financially meaningful, but the retrieved evidence cannot prove that they caused the subsequent relative outperformance. A formal consensus-surprise record, peer comparison, and event-study or flow evidence would be needed to strengthen or change the causal interpretation.
