Bridgeline Digital Announces Earnings for First Quarter of Fiscal 2019

Burlington, Mass., February 14, 2019 - Bridgeline Digital, Inc. (NASDAQ: BLIN), The Digital Engagement Company™, today announced financial results for its fiscal first quarter ended December 31, 2018.

“Bridgeline’s focus in 2019 to reduce customer acquisition cost through strategic expansion of its customer base and product suite in the crowded Marketing Technology sector has already made great progress. I am happy to announce that Bridgeline acquired strategic assets from SeeVolution this week. SeeVolution, and its Celebros search products, add substantial SaaS revenue and dozens of new customers, increases our international presence, and establishes us in the eCommerce search space with Natural Language Processing Artificial Intelligence technology,” said Ari Kahn, Bridgeline’s President and Chief Executive Officer. “As mentioned in our last earnings call, the revenue in our first quarter was impacted by the cancellation of a large license, however, moving forward, Celebros offsets that revenue with a diverse new revenue stream spread across more than 80 customers and gives us a strategic product line to make us an even stronger business.”

Non-GAAP Financial Measures

This press release contains the following non-GAAP financial measures: non-GAAP adjusted net income/(loss), non-GAAP adjusted earnings/(loss) per diluted share, Adjusted EBITDA and Adjusted EBITDA per diluted share.

Non-GAAP adjusted net income/(loss) and non-GAAP adjusted earnings/(loss) per diluted share are calculated as net income/(loss) or net income/(loss) per share on a diluted basis, excluding, where applicable, amortization of intangible assets, stock-based compensation, goodwill impairment charges, preferred stock dividends and any related tax effects.

Adjusted EBITDA and Adjusted EBITDA per diluted share are defined as earnings before interest, taxes, depreciation and amortization, stock-based compensation charges, goodwill impairment charges, preferred stock dividends and any related tax effects. Bridgeline uses non-GAAP adjusted net income/(loss) and Adjusted EBITDA as supplemental measures of our performance that are not required by, or presented in accordance with, accounting principles generally accepted in the United States (“GAAP”).

Bridgeline’s management does not consider these non-GAAP measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these non-GAAP financial measures is that they exclude significant expenses and income that are required by GAAP to be recorded in the Company's financial statements. In addition, they are subject to inherent limitations as they reflect the exercise of judgments by management about which expenses and income are excluded or included in determining these non-GAAP financial measures. In order to compensate for these limitations, Bridgeline management presents non-GAAP financial measures in connection with GAAP results. Bridgeline urges investors to review the reconciliation of its non-GAAP financial measures to the comparable GAAP financial measures, which is included in this press release, and not to rely on any single financial measure to evaluate Bridgeline's financial performance.

Our definitions of non-GAAP adjusted net income/(loss) and Adjusted EBITDA may differ from and therefore may not be comparable with similarly titled measures used by other companies, thereby limiting their usefulness as comparative measures. As a result of the limitations that non-GAAP adjusted net income and Adjusted EBITDA have as an analytical tool, investors should not consider them in isolation, or as a substitute for analysis of our operating results as reported under GAAP.
