SAN FRANCISCO, Oct. 30, 2017 /PRNewswire/ -- RPX Corporation (NASDAQ: RPXC), the leading provider of patent risk and discovery management solutions, today announced its financial results for the third quarter ended September 30, 2017.

Highlights

Total revenue was $85.7 million, compared to $88.5 million in the third quarter of 2016.


    --  Subscription revenue from patent risk management services--including
        insurance--was $62.3 million, compared to $62.4 million in the prior
        year period.
    --  Discovery services revenue was $21.1 million, compared to $18.0 million
        in the prior year period.

"RPX posted a solid third quarter, with results exceeding expectations in both our patent risk management and discovery services businesses, along with increasing cash flow," Marty Roberts, CEO of RPX Corp. "We also have made progress in identifying new emerging business opportunities that leverage our unique position in the patent space, including tech-enabled services, new licensing models and expansion into foreign jurisdictions."

Summary Results

GAAP net income for the third quarter was $6.4 million or $0.13 per diluted share, compared to $8.1 million or $0.16 per diluted share in the third quarter of 2016.

Non-GAAP net income for the third quarter, which excludes stock-based compensation, the amortization of acquired intangibles, fair value adjustments on deferred payment obligations, gains on extinguishment of deferred payment obligations, realized losses on exchange of short-term investments, and their related tax effects, was $10.9 million or $0.22 per diluted share, compared to $12.7 million or $0.25 per diluted share in the third quarter of 2016.

Non-GAAP adjusted EBITDA was $57.2 million for the third quarter of 2017, less net patent spend of $13.0 million, resulting in non-GAAP adjusted EBITDA less net patent spend, the Company's preferred measure of adjusted pre-tax free cash flow, of $44.2 million for the third quarter of 2017.

As of September 30, 2017, RPX's patent segment had more than 325 clients, consisting of patent risk management network members and insurance clients. The Company provides patent risk management services to nearly 450 companies, including those insured under policies sold to venture funds and industry trade associations.

Net patent acquisition spend during the quarter totaled $13.0 million, and included 11 patent transactions.

As of September 30, 2017, RPX had cash, cash equivalents and short-term investments of $267.5 million and long-term debt of $89.9 million.

Quarterly Dividend and Repayment of Term Facility

The Company also announced that its Board of Directors had approved a regular quarterly cash dividend of $0.05 per share of common stock, the first of which is payable on December 5, 2017, to stockholders of record on November 20, 2017.

In addition, the Company announced that it will be repaying the approximately $91.3 million outstanding under its term facility in the fourth quarter of 2017. The original terms of the five-year term facility entered into in February 2016 required quarterly repayments through 2021. Pursuant to the terms of the credit agreement, the Company will not incur any early termination costs by early repayment of this facility. The revolving credit facility will remain available for use.

"These changes to our capital structure reflect the Board's confidence in the long term opportunity for RPX and reinforce its commitment to delivering value to shareholders, even as we continue investing to grow the business," said Marty Roberts.

    [1]            Subscription revenue is comprised
                   of revenue generated from
                   membership subscription services,

                   commissions, from insurance
                   policies, and management fees
                   related to the Company's
                   insurance business.

    [2]            RPX excludes amortization expense
                   related to intangible assets
                   (other than patents) acquired in
                   conjunction with the acquisition

The above outlook is forward-looking. Actual results may differ materially. The Company is not able, at this time, to provide a forward-looking reconciliation to GAAP outlook for the non-GAAP financial metric outlook it has provided above for the fourth quarter and full year 2017 because of the difficulty of estimating certain items that are excluded from the non-GAAP financial metrics, including those items listed in "Use of Non-GAAP Financial Information" below, the effect of which may be significant. Please refer to the information under the caption "Use of Non-GAAP Financial Information" below.

Use of Non-GAAP Financial Information

This news release dated October 30, 2017 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 interest and other income (expense), net, non-GAAP net income, non-GAAP adjusted EBITDA, non-GAAP net income per share, and non-GAAP adjusted EBITDA less net patent spend.

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), (3) fair value adjustments on deferred payment obligations, (4) gains on extinguishment of deferred payment obligations, (5) other-than-temporary impairment on short-term investments, (6) realized losses on exchange of short-term investments, and (7) their related tax effects.

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.
