Exhibit 99.3

UNAUDITED COMBINED CONDENSED PRO FORMA FINANCIAL INFORMATION

We have derived the following unaudited combined condensed pro forma financial information by applying pro forma adjustments to the historical consolidated financial statements of SolarWinds, Inc. (“SolarWinds”) included in our Annual Report on Form 10-K for the year ended December 31, 2009 filed with the Securities and Exchange Commission on February 24, 2010. For purposes of the presentation of the Unaudited Condensed Combined Pro Forma Balance Sheet, the adjustments were reflected as of December 31, 2009. The Unaudited Combined Condensed Pro Forma Statement of Income, as adjusted, gives pro forma effect to the acquisition of Tek-Tools, Inc. (“Tek-Tools”) as if the acquisition occurred on January 1, 2009. We collectively refer to the adjustments relating to the Tek-Tools acquisition as the “Acquisition Adjustments.” We have described the adjustments, which are directly attributable to the transaction and assumptions that management believes to be reasonable, in the accompanying notes. The unaudited combined condensed pro forma financial information is for informational purposes only and should not be considered indicative of actual results that would have been achieved had the acquisition actually been consummated on the dates indicated and does not purport to be indicative of results of operations as of any future date or for any future period.

On January 26, 2010, we acquired certain of the assets of Tek-Tools for the following: (i) $26.0 million of cash; (ii) 362,138 shares of our common stock with a value of approximately $7.4 million based on the closing price of our common stock as reported on the New York Stock Exchange on January 26, 2010; (iii) $2.0 million of cash and 90,535 shares of our common stock with a value of approximately $1.8 million based on the closing price of our common stock on January 26, 2010, each being held in escrow as security for breaches of representations and warranties, covenants and certain other expressly enumerated matters by Tek-Tools and its stockholders; (iv) $2.0 million of cash being withheld to be paid upon the achievement of sales milestones of the acquired business during calendar year 2010; and (v) $2.0 million of cash being withheld to be paid upon the receipt of certain third-party consents. Tek-Tools provided us an immediate product offering of storage and virtualized server infrastructures that was missing from our product offerings and eliminated the normal time to market required to develop a new software product. We accounted for the Tek-Tools acquisition using the purchase method of accounting. We allocated the purchase price to the assets acquired, including intangible assets, and liabilities assumed based on estimated fair values at the date of the acquisition. We estimated the value of assets and liabilities based on purchase price and future intended use. We derived the value of intangible assets from the present value of estimated future benefits from the various intangible assets acquired. Goodwill represents the excess of the purchase price over the aggregate fair value of the net identifiable assets acquired. As of the date of the Current Report on Form 8-K/A to which this exhibit relates, we have not finalized the valuation studies necessary to arrive at the required estimates of the fair value of the Tek-Tools assets acquired and liabilities assumed and the related allocations of purchase price.

The unaudited combined condensed pro forma financial information is prepared for illustrative purposes only and is not necessarily indicative of or intended to represent the results that would have been achieved had the transactions been consummated as of the date indicated or that may be achieved in the future. The unaudited condensed combined pro forma statement of income does not reflect any operating efficiencies and associated cost savings that we may achieve with respect to the combined companies.

The unaudited combined condensed pro forma financial information should be read in conjunction with SolarWinds historical consolidated financial statements and accompanying notes included in our Annual Report on Form 10-K for the year ended December 31, 2009 filed with the Securities and Exchange Commission on February 24, 2010 and the historical financial statements of Tek-Tools also included in the Current Report on Form 8-K/A to which this exhibit relates.
