Expects Revenue and Adjusted EBITDA to Exceed Prior Guidance

Full First Quarter 2018 Financial Results to be Announced on May 10, 2018

Research Triangle Park, NCApril 19, 2018 – ChannelAdvisor Corporation (NYSE: ECOM), a leading provider of cloud-based e-commerce solutions that enable retailers and branded manufacturers to increase global sales, today announced preliminary estimated financial results for the first quarter of 2018.

Based on information available as of today, total revenue is expected to be approximately $31.2 million, or $1.4 million above the high end of the previous guidance range of $29.4 million to $29.8 million. Adjusted EBITDA, a non-GAAP measure, is expected to be approximately $0.8 million, or $1.1 million above the high end of the previous guidance range of a loss of $(0.7) million to $(0.3) million. ChannelAdvisor’s adjusted EBITDA estimate includes an expected net loss of $(3.4) million adjusted for interest income of $(0.1) million, as well as depreciation and amortization expenses of $1.5 million, income tax expense of $0.1 million and stock-based compensation expense of $2.7 million. These results are preliminary and unaudited and are subject to change based on the completion of the company’s normal quarter-end review process. As a result, these preliminary results may be different from the actual results that will be reflected in ChannelAdvisor’s consolidated financial statements for the quarter ended March 31, 2018 when they are released.

“Our preliminary analysis of our first quarter performance indicates that revenue and adjusted EBITDA will be above our previous guidance for the first quarter, reflecting solid execution against our plan,” said David Spitz, CEO of ChannelAdvisor. “These anticipated results reflect our continued emphasis on driving revenue growth while improving the efficiency of our business. We look forward to providing final results and additional color on May 10.”

ChannelAdvisor will release its full first quarter 2018 financial results for the quarter ended March 31, 2018 before 8:00 a.m. ET on Thursday, May 10, 2018.

Non-GAAP Financial Measures

This press release contains the following non-GAAP financial measure: adjusted EBITDA.

ChannelAdvisor believes that non-GAAP measures of financial results provide useful information to management and investors relating to ChannelAdvisor’s financial condition and results of operations. The company’s management uses non-GAAP measures to compare the company’s performance to that of prior periods for trend analyses, and for budgeting and planning purposes. The company believes that the use of non-GAAP financial measures provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing the company’s financial measures with other software companies, many of which present similar non-GAAP financial measures to investors, and that it allows for greater transparency with respect to key metrics used by management in its financial and operational decision-making.

Management of the company does not consider non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of non-GAAP financial measures is that they exclude significant expenses that are required by GAAP to be recorded in the company’s financial statements. In order to compensate for these limitations, management presents non-GAAP financial measures together with GAAP results. Non-GAAP measures should be considered in addition to results and guidance prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. Reconciliation tables of the most comparable GAAP financial measures to the non-GAAP financial measures used in this press release are included with the financial tables at the end of this release. ChannelAdvisor urges investors to review the reconciliation and not to rely on any single financial measure to evaluate the company’s business. In addition, other companies, including companies in our industry, may calculate similarly named non-GAAP measures differently than we do, which limits their usefulness in comparing our financial results with theirs.

Cautionary Language Concerning Forward-Looking Statements
