Business Outlook

“Our business is being driven by our advertiser demand for mobile performance. Our Call-Driven products and investments are centered on unlocking this opportunity,” said Mike Arends, Chief Financial Officer of Marchex. “Given the relative size and importance of our Call-Driven products, we believe that focusing on these revenue and profitability measures is the most appropriate way to communicate our business progress and guidance going forward. While advertiser budgets can change and we can experience period-to-period variability based on a variety of factors, we are excited about the ongoing progress we are making in our business. Today we are forecasting accelerated Call-Driven revenue year-over-year growth of approximately 30% in the first quarter.”

The following forward-looking statements reflect Marchex’s expectations as of February 19, 2014 and exclude any contribution from Archeo operations, domain sales and discontinued operations. Archeo operating results would be incremental and additive to our Call-Driven revenue, profitability, and other measures below:

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 19, 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 excluding and including Domain Sales, and Adjusted OIBA and EBITDA excluding and including Domain Sales. Marchex also provides Call-Driven and Archeo Adjusted OIBA and EBITDA, and Adjusted non-GAAP EPS.

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 any gain/loss on sales and disposals of intangible assets for each asset and acquisition and separation related costs as these items are not indicative of Marchex’s recurring core operating results and any domain sales contribution. 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 or gain/loss such as stock-based compensation, amortization of intangible assets from acquisitions, acquisition and separation related costs, domain sales contribution and gain/loss on sales and disposals of intangible assets. Adjusted EBITDA represents income (loss) before interest, income taxes, depreciation, amortization, stock compensation expense, acquisition and separation related cost, domain sales contribution and gain/loss on sales and disposals of intangible 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.

Revenue excluding Domain Sales represents GAAP revenue excluding domain sales sold through Marchex’s Domain Marketplace which are recognized in GAAP revenue. Revenue with Domain Sales represents GAAP revenue plus sales proceeds from the sale of intangible assets. Adjusted OIBA and EBITDA with Domain Sales includes the above descriptions of Adjusted OIBA and EBITDA plus any 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 indirect overhead costs to the Call-Driven results. Archeo non-GAAP Measures include the measures above for the Archeo segment. Financial analysts and investors may use the non-GAAP historical Revenue with Domain Sales, Adjusted OIBA and EBITDA with Domain Sales to help with comparative financial evaluation to make informed investment decisions.

Adjusted non-GAAP EPS represents Adjusted non-GAAP Net Income (Loss) applicable to common stockholders divided by GAAP diluted shares outstanding. Adjusted non-GAAP Net Income (Loss) 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 (loss) applicable to common stockholders plus the net of tax effects of: (1) stock-based compensation expense, (2) amortization of intangible assets from acquisitions, (3) domain sales contribution and gain/loss on sales and disposals of intangible assets and domain sales contribution, (4) acquisition and separation related costs, (5) interest and other income (expense), (6) discontinued operations and gain on sale of discontinued operations, net of tax and (7) dividends paid to participating securities, and also excludes the effect of the 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.

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.
