Summary Results

Revenue for the first quarter of 2018 and 2017 was $67.1 million and $75.4 million, respectively.

GAAP net income for the first quarter was $0.1 million or $0.00 per diluted share, compared to $5.7 million or $0.11 per diluted share in the first quarter of 2017.

Non-GAAP net income for the first quarter, which excludes stock-based compensation, the amortization of acquired intangibles and their related tax effects, was $4.9 million or $0.10 per diluted share, compared to $9.2 million or $0.19 per diluted share in the first quarter of 2017.

The Company generated free cash flow of $15.1 million of free cash flow in the first quarter ended March 31, 2018, which it defines as cash flow from operating activities less capital expenditures such as property and equipment and patent assets. Non-GAAP adjusted EBITDA was $37.1 million for the first quarter of 2018, less net patent spend of $17.3 million, resulting in non-GAAP adjusted EBITDA less net patent spend, of $19.8 million for the first quarter of 2018.

Use of Non-GAAP Financial Information

This news release dated May 1, 2018 contains non-GAAP financial measures. Tables are provided in this news release that reconcile the historical 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 cost of revenue, non-GAAP selling, general and administrative expenses, non-GAAP provision for income taxes, non-GAAP net income, non-GAAP adjusted EBITDA, non-GAAP net income per share, non-GAAP adjusted EBITDA less net patent spend, and free cash flow.

To supplement the Company’s condensed 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 is excluding from some or all of its non-GAAP operating results (1) stock-based compensation expenses (inclusive of related employer payroll taxes), (2) the amortization of acquired intangible assets (other than patents), and (3) the related tax effects of these exclusions.

2

Management uses these non-GAAP measures to evaluate the Company’s financial results and trends, allocate internal resources, prepare and approve our annual budget, develop short- and long-term operating plans, assess the health of our business and determine company-wide incentive compensation. Management believes these non-GAAP measures may prove useful to investors who wish to consider the impact of certain items when comparing the Company’s financial performance with that of other companies. The 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, trends and performance.

There are limitations in using non-GAAP financial measures because non-GAAP financial measures are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. The non-GAAP financial measures are limited in value because they exclude certain items that may have a material impact on our reported financial results. In addition, they are subject to inherent limitations as they reflect the exercise of judgment by management about which items are adjusted to calculate our non-GAAP financial measures. Management compensates for these limitations by analyzing current and future results on a GAAP basis as well as a non-GAAP basis and also by providing GAAP measures in our public disclosures.

The presentation of additional information should not be considered in isolation or as a substitute for or superior to financial results determined in accordance with GAAP. Investors are encouraged to review the reconciliation of these non-GAAP measures to their most directly comparable GAAP financial measure and not to rely on any single financial measure to evaluate our business.

that could ultimately prove inaccurate. As a general matter, forward-looking statements are those focused upon anticipated events or trends, expectations, and beliefs relating to matters that are not historical in nature. Such forward-looking statements are subject to uncertainties and factors relating to RPX’s operations and business environment, all of which are difficult to predict and many of which are beyond the control of RPX. Among others, the following factors could cause actual results to differ materially from those set forth in the forward-looking statements: (i) uncertainties as to the timing of the tender offer and the anticipated merger; (ii) uncertainties as to how many RPX stockholders will tender their shares of RPX common stock in the anticipated merger; (iii) the possibility that competing offers will be made; (iv) the possibility that various closing conditions for the transaction may not be satisfied or waived; (v) the risk that the merger agreement may be terminated in circumstances requiring RPX to pay a termination fee; (vi) risks related to obtaining the requisite consents to the tender offer and the anticipated merger, including, without limitation, the risk that a regulatory approval that may be required for the proposed transaction, including under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 (HSR Act) and the German Act of Restraints of Competition 1957, as amended (GWB), is delayed, is not obtained, or is obtained subject to conditions that are not anticipated; (vii) the possibility that the transaction may not be timely completed, if at all; (viii) the risk that, prior to the completion of the transaction, if at all, RPX’s business and its relationships with employees, collaborators, vendors and other business partners could experience significant disruption due to transaction-related uncertainty; (ix) the risk that stockholder litigation in connection with the tender offer or the anticipated merger may result in significant costs of defense, indemnification and liability; and (x) the risks and uncertainties pertaining to RPX’s business, including those detailed under “Risk Factors” and elsewhere in RPX’s public periodic filings with the SEC, as well as the tender offer materials to be filed by Purchaser and the Solicitation/Recommendation Statement to be filed by RPX in connection with the tender offer. Other factors that could cause actual results to differ materially include those set forth in RPX’s SEC reports, including, without limitation, the risks described in RPX’s Annual Report on Form 10-K for its fiscal year ended December 31, 2017, which is on file with the SEC. The reader is cautioned not to place undue reliance on these forward-looking statements, which speak only as of the date hereof.
