RPX Announces Third Quarter 2011 Financial Results

SAN FRANCISCO – November 1, 2011 – RPX Corporation (NASDAQ: RPXC), a leading provider of patent risk solutions, offering defensive buying, acquisition syndications, patent intelligence and advisory services, today announced its financial results for the third quarter ended September 30, 2011.

Third Quarter 2011 Highlights

• Revenue totaled $38.4 million, up 53% from the prior year period

• Client network grew to 103 with 7 net clients added in the third quarter

• GAAP net income was $7.9 million or $0.15 per diluted share on a pro forma basis

• Non-GAAP net income was $9.0 million or $0.17 per diluted share on a pro forma basis

“Our third quarter results came in solidly at the high end of our guidance range as we continued to expand our client network,” said John Amster, CEO of RPX Corporation. “We added seven clients during the quarter bringing the total to 103 clients in our network, and we deployed approximately $29 million in RPX capital to purchase patents and patent rights on behalf of our clients.”

Summary Results

Revenue for the third quarter of 2011 increased 53% to $38.4 million, compared to $25.1 million in the third quarter of 2010.

Cost of revenue for the quarter was $16.5 million, compared to $12.4 million in the year-ago period. Net acquisition spend during the quarter totaled $29.3 million, and included 13 new acquisitions of patent assets, in addition to the exercise of previously negotiated options to acquire licenses for new members. The net book value of RPX’s portfolio of patent assets increased to $153.0 million as of September 30, 2011 from $139.8 million as of June 30, 2011.

Selling, general, and administrative expenses were $9.1 million in the third quarter of 2011, compared to $5.9 million in the third quarter of 2010. Non-GAAP selling, general, and administration expenses, which exclude stock-based compensation and the amortization of acquired intangibles, were $7.1 million in the third quarter of 2011, compared to $5.6 million in the prior year period. Both GAAP and non-GAAP expenses reflected the benefit of a $2.1 million recovery of previously expensed costs associated with an incomplete syndicated acquisition effort.

GAAP net income for the quarter was $7.9 million or $0.15 per diluted share, compared to $3.6 million or $0.06 per diluted share in the third quarter of 2010. On a pro forma basis giving effect to the restricted stock outstanding and the conversion of all preferred shares into common shares at the beginning of the period, net income was $0.15 per pro forma diluted share in the third quarter of 2011, compared to $0.09 per pro forma diluted share in the prior year period. Non-GAAP net income, which excludes stock-based compensation and the amortization of acquired intangibles (in each case, net of tax), was $9.0 million or $0.17 per pro forma diluted share in the third quarter of 2011, compared to $3.8 million or $0.10 per pro forma diluted share in the prior year period.

The Company completed a secondary offering of its common stock in September 2011, through which it sold 1.4 million newly-issued common shares and raised proceeds of $26.9 million, after underwriting fees and offering

Use of Non-GAAP Financial Information

The accompanying news release dated November 1, 2011 contains non-GAAP financial measures. Tables are provided in this news release that reconcile the non-GAAP financial measures to the most directly comparable financial measures prepared in accordance with Generally Accepted Accounting Principles (GAAP). These non-GAAP financial measures include non-GAAP net income, non-GAAP cost of revenue, non-GAAP selling, general, and administrative expense, and non-GAAP earnings per share. To supplement the Company’s consolidated financial statements presented on a GAAP basis, management believes that these non-GAAP measures provide useful information about the Company’s core operating results and thus are appropriate to enhance the overall understanding of the Company’s past financial performance and its prospects for the future. Management believes it is useful to report non-GAAP measures which exclude stock-based compensation expense and the amortization of acquired intangible assets, because it believes investors wish to exclude the effects of stock-based compensation expense and the amortization of acquired intangible assets in comparing our financial performance with that of other companies. These adjustments to the Company’s GAAP results are made with the intent of providing both management and investors a more complete understanding of the Company’s underlying operational results and trends and performance. Management uses these non-GAAP measures to evaluate the Company’s financial results. The presentation of additional information is not meant to be considered in isolation or as a substitute for or superior to financial results determined in accordance with GAAP.

The Company’s actual results may differ materially from those anticipated in these forward-looking statements.
