Marchex Announces Second Quarter 2016 Results

SEATTLE — (BUSINESS WIRE) – August 9, 2016—Marchex, Inc. (NASDAQ:MCHX), a leading mobile advertising analytics company, today announced its financial results for the second quarter ended June 30, 2016.

“We are disappointed with our Q2 financial results and revised 2016 outlook, which were primarily driven by a small number of our large clients that reduced their marketing spend,” said Pete Christothoulou, CEO. “It does not impact our long-term relationship with these clients or our belief in the Online-to-Offline opportunity. Our new client wins and strong customer feedback point to a growing pipeline. We are eager to see our strategic progress flow through to our financial performance and, ultimately, category leadership.”

Q2 2016 Financial Highlights

Strategic Priorities Update

The following highlights our recent progress:

Grow New and Existing Enterprise Client Relationships

Accelerate Product Innovation

Expand Global Strategic Partnerships

Business Outlook

The following forward-looking statements reflect Marchex’s expectations as of August 9, 2016.

Total Call-Driven financial guidance for the Third Quarter ending September 30, 2016

We are providing annual guidance on Call-Driven revenue which includes anticipated contributions by YP due to increased visibility in the remaining year outlook from this customer. We anticipate Enterprise Revenue for the full year will be lower than our previously stated annual guidance, primarily due to increasing variability in marketing budgets from a small number of our largest enterprise customers.

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 August 9, 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 earnings (loss) per share and Call-Driven and Archeo and Other Adjusted OIBA and EBITDA. Additionally, Marchex also provides Enterprise Revenue, which represents Call-Driven revenue excluding revenue generated from our contracts with Yellowpages.com LLC (“YP”).

OIBA represents income (loss) from operations plus stock-based compensation expense. 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 preliminary estimate of impairment of goodwill, 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, acquisition and disposition related costs, and preliminary estimate of impairment of goodwill. Adjusted EBITDA represents income before interest, income taxes, depreciation, amortization, stock compensation expense, acquisition and disposition related costs, and preliminary estimate of impairment of goodwill. Marchex believes that Adjusted EBITDA is another alternative measure of liquidity to GAAP net cash provided by (used in) 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 includes all Marchex general corporate overhead costs. Archeo and Other Adjusted OIBA and EBITDA includes the above descriptions of Adjusted OIBA and EBITDA for the Archeo segment in 2015, and in 2016, Other operating results primarily includes transition activities provided to buyer of Archeo assets which are not material. Enterprise Revenue represents Call-Driven revenue excluding revenue generated through our contracts

with YP. Financial analysts and investors may use Adjusted OIBA and EBITDA and Enterprise Revenue to help with comparative financial evaluation to make informed investment decisions. Net loss from continuing operations excluding impairment of goodwill and related per diluted share amount represents GAAP net loss from continuing operations adding back the impact of the preliminary estimate of impairment of goodwill with the corresponding diluted share amount derived by using GAAP diluted shares outstanding. Adjusted non-GAAP earnings (loss) per share 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) acquisition and disposition related costs, (3) interest and other income (expense), (4) discontinued operations, net of tax, (5) dividends paid to participating securities and (6) preliminary estimate of impairment of goodwill. Financial analysts and investors may use Adjusted non-GAAP earnings (loss) per share 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.
