All of the information provided in this release is as of August 5, 2014 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, Revenue including and excluding domain gains and sales, Adjusted OIBA, EBITDA including and excluding domain gains and sales and Adjusted non-GAAP EPS including and excluding domain gains and sales. Marchex also provides Call-Driven Adjusted OIBA and EBITDA.

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 separation related costs, as this item is 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 and acquisition and separation related costs. Adjusted EBITDA represents income

before interest, income taxes, depreciation, amortization, stock compensation expense and acquisition and separation related cost. 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. Historically, these Non-GAAP measures excluded gain/loss on sales and disposals of intangible assets for each asset and any domain sales contribution.

Non-GAAP Revenue represents GAAP revenue excludes domain sales sold through Marchex’s Domain Marketplace, which are recognized in GAAP revenue. Archeo revenue including or excluding domain gains and sales represents GAAP revenue and includes/excludes sales proceeds from the sale of domains recognized in gain/loss on sales and disposals of intangible assets and domain sales sold through Marchex’s Domain Marketplace which are recognized in GAAP revenue. Adjusted OIBA and EBITDA including or excluding domain gains and sales includes the above descriptions of Adjusted OIBA and EBITDA and includes/excludes domain sales contribution and gain/loss on sales and disposals of intangible assets. Call-Driven Adjusted OIBA and EBITDA includes the above descriptions of Adjusted OIBA and EBITDA for the Call-Driven segment. The Call-Driven Adjusted OIBA and EBITDA assigns all Marchex general corporate overhead costs to the Call-Driven results. Financial analysts and investors may use the non-GAAP historical Revenue including/excluding domain gains and sales and Adjusted OIBA and EBITDA including/excluding domain gains and sales 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 separation related costs, (4) interest and other income (expense), (5) discontinued operations, net of tax and (6) dividends paid to participating securities, and also excludes the effect of any tax valuation allowance. 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. Adjusted Non-GAAP EPS excluding domain gains and sales includes the above description of Adjusted non-GAAP EPS and excludes domain sales contribution and gain/loss on sales and disposals of intangible assets.

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.
