• The company operates in a very competitive and rapidly changing environment, which could impact its ability to maintain market share and profitability.

• Risks and uncertainties are detailed in the sections titled 'Risk Factors' and 'Management's Discussion and Analysis of Financial Condition and Results of Operations' in the company's Annual Report on Form 10-K for the year ended December 31, 2024, and Quarterly Report on Form 10-Q for the quarter ended September 30, 2025.

Future Outlook

For the first quarter of 2026, Tenable expects revenue in the range of $257.0 million to $260.0 million, non-GAAP income from operations between $53.0 million and $56.0 million, and non-GAAP diluted earnings per share of $0.39 to $0.42.

The company will no longer provide specific guidance for calculated current billings due to negative distortion from a shift to annual installment billing, but expects full year 2026 calculated current billings to be in line with current consensus expectations despite anticipated headwinds.
