Item 2.02 Results of Operations and Financial Condition.

On February 11, 2026, Cisco Systems, Inc. (“Cisco”) reported its results of operations for its fiscal second quarter 2026 ended January 24, 2026. A copy of the press release issued by Cisco concerning the foregoing results is furnished herewith as Exhibit 99.1.

The information contained herein and in the accompanying exhibit shall not be incorporated by reference into any filing of Cisco, whether made before or after the date hereof, regardless of any general incorporation language in such filing, unless expressly incorporated by specific reference to such filing. The information in this report, including the exhibit hereto, shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section or Sections 11 and 12(a)(2) of the Securities Act of 1933, as amended.

The attached exhibit includes non-GAAP net income, non-GAAP gross margins, non-GAAP operating expenses, non-GAAP operating income and margin, non-GAAP effective tax rates, non-GAAP interest and other income (loss), net, and non-GAAP net income per share data for the periods presented. It also includes future estimated ranges for gross margin, operating margin, tax provision rate and EPS on a non-GAAP basis.

These non-GAAP measures are not in accordance with, or an alternative for, measures prepared in accordance with generally accepted accounting principles, and may be different from non-GAAP measures used by other companies. In addition, these non-GAAP measures are not based on any comprehensive set of accounting rules or principles. Cisco believes that non-GAAP measures have limitations in that they do not reflect all of the amounts associated with Cisco's results of operations as determined in accordance with GAAP and that these measures should only be used to evaluate Cisco's results of operations in conjunction with the corresponding GAAP measures.

Cisco believes that the presentation of non-GAAP measures when shown in conjunction with the corresponding GAAP measures, provides useful information to investors and management regarding financial and business trends relating to its financial condition and its historical and projected results of operations.

For its internal budgeting process, Cisco’s management uses financial statements that do not include, when applicable, share-based compensation expense, amortization of acquisition-related intangible assets, acquisition-related/divestiture costs, significant asset impairments and restructurings, significant litigation settlements and other contingencies (such as legal and indemnification set
