Forward-Looking Statements:

This press release contains forward-looking statements that involve substantial risks and uncertainties. All statements, other than statements of historical facts, included in this press release regarding our strategy, future operations, future financial position, future revenues, other financial guidance, acquisitions, dispositions, projected costs, prospects, plans and objectives of management are forward-looking statements. We may not actually achieve the plans, intentions, or expectations disclosed in our forward-looking statements and you should not place undue reliance on our forward-looking statements. Actual results or events could differ materially from the plans, intentions and expectations disclosed in the forward-looking statements we make. There are a number of important factors that could cause Marchex’s actual results to differ materially from those indicated by such forward-looking statements which are described in the “Risk Factors” section of our most recent periodic report and registration statement filed with the SEC. All of the information provided in this release is as of February 18, 2016 and Marchex undertakes no duty to update the information provided herein.

Non-GAAP Financial Information:

To supplement Marchex’s consolidated financial statements presented in accordance with GAAP and to provide clarity internally and externally, Marchex uses certain non-GAAP measures of financial performance and liquidity, including OIBA, Adjusted OIBA, Adjusted EBITDA, Adjusted non-GAAP EPS and Call-Driven and Archeo Adjusted OIBA and EBITDA. Additionally, Marchex also provides Call-Driven and Archeo Revenue excluding revenue generated from our contracts with Yellowpages.com LLC (“YP”).

OIBA represents income (loss) from operations plus (1) stock-based compensation expense and (2) amortization of intangible assets from acquisitions. This measure, among other things, is one of the primary metrics by which Marchex evaluates the performance of its business. Additionally, Marchex’s management uses Adjusted OIBA, which excludes acquisition and disposition related costs, and gain on sale of Archeo assets, as these items are not indicative of Marchex’s recurring core operating results. Adjusted OIBA is the basis on which Marchex’s internal budgets are based and by which Marchex’s management is currently evaluated. Marchex believes these measures are useful to investors because they represent Marchex’s consolidated operating results, taking into account depreciation and other intangible amortization, which Marchex believes is an ongoing cost of doing business, but excluding the effects of certain other expenses such as stock-based compensation, amortization of intangible assets from acquisitions, acquisition and disposition related costs, and gain on sale of Archeo assets. Adjusted EBITDA represents income before interest, income taxes, depreciation, amortization, stock compensation expense, acquisition and disposition related costs, and gain on sale of Archeo assets . Marchex believes that Adjusted EBITDA is another alternative measure of liquidity to GAAP net cash provided by operating activities that provides meaningful supplemental information regarding liquidity and is used by Marchex’s management to measure its ability to fund operations and its financing obligations.

Call-Driven Adjusted OIBA and EBITDA include the above descriptions of Adjusted OIBA and EBITDA for the Call-Driven segment. The Call-Driven Adjusted OIBA and EBITDA assign all Marchex general corporate overhead costs to the Call-Driven results. Archeo Adjusted OIBA and EBITDA include the above descriptions of Adjusted OIBA and EBITDA for the Archeo segment. Call-Driven and Archeo Revenue excluding YP excludes revenue generated through our contracts with YP. Financial analysts and investors may use Adjusted OIBA and EBITDA and Revenue excluding YP to help with comparative financial evaluation to make informed investment decisions. Adjusted non-GAAP EPS represents Adjusted non-GAAP net income applicable to common stockholders divided by GAAP diluted shares outstanding. Adjusted non-GAAP net income applicable to common stockholders generally captures those items on the statement of operations that have been, or ultimately will be, settled in cash exclusive of certain items that are not indicative of Marchex’s recurring core operating results and represents net income applicable to common stockholders plus the net of tax effects of: (1) stock-based compensation expense, (2) amortization of intangible assets from acquisitions, (3) acquisition and disposition related costs, (4) interest and other income (expense), (5) discontinued operations, net of tax, (6) dividends paid to participating securities, and (7) gain on sale of Archeo assets. Financial analysts and investors may use Adjusted non-GAAP EPS to analyze Marchex’s financial performance since these groups have historically used EPS related measures, along with other measures, to estimate the value of a company, to make informed investment decisions, and to evaluate a company’s operating performance compared to that of other companies in its industry.

Marchex’s management believes that investors should have access to, and Marchex is obligated to provide, the same set of tools that management uses in analyzing the company’s results. These non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, and should not be considered in isolation, as a substitute for, or superior to, GAAP results. Marchex’s non-GAAP financial measures may be defined differently from time to time and may be defined differently than similar titled terms used by other companies, and accordingly, care should be exercised in understanding how Marchex defines its non-GAAP financial measures in this release. Marchex endeavors to compensate for the limitations of the non-GAAP measures presented by providing the comparable GAAP measure with equal or greater prominence, GAAP financial statements, and detailed descriptions of the reconciling items and adjustments, including quantifying such items, to derive the non-GAAP measure.
