Forward Looking Statements Certain statements included in this Presentation are not historical facts but are forward-looking statements for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as "believe," "may," "will," "estimate," "continue," "anticipate," "intend," "expect," "should," "would," "plan," "predict," "potential," "seem," "seek," "future," "outlook," and similar expressions that predict or indicate future events or trends or that are not statements of historical matters, but the absence of these words does not mean that a statement is not forward-looking. These forward-looking statements include, but are not limited to, statements regarding estimates and forecasts of other financial and performance metrics and projections of market opportunity. These statements are based on various assumptions, whether or not identified in this Presentation, and on the current expectations of Barkbox's management and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on by any investor as, a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of Barkbox. Some important factors that could cause actual results to differ materially from those in any forward-looking statements could include changes in domestic and foreign business, market, financial, political and legal conditions. These forward-looking statements are subject to a number of risks and uncertainties; the inability of the parties to successfully or timely consummate the Potential Business Combination, including the risk that any required regulatory approvals are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the Potential Business Combination s not obtained; failure to realize the anticipated benefits of the Potential Business Combination; risks relating to the uncertainty of the projected financial information with respect to the Barkbox; the risk that spending on pets may not increase at projected rates; that Barkbox subscriptions may not increase their spending with Barkbox; Barkbox's ability to continue to convert social media followers and contacts into customers; Barkbox's ability to successfully expand its product lines and channel distribution; competition; the uncertain effects of the COVID-19 pandemic; and those factors discussed in documents of Northern Star filed, or to be filed, with SEC. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither Northern Star nor Barkbox presently know or that Northern Star and Barkbox currently believe are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Northern Star's and Barkbox's expectations, plans or forecasts of future events and views as of the date of this Presentation. Northern Star and Barkbox anticipate that subsequent events and developments will cause Northern Star's and Barkbox's assessments to change. However, while Northern Star and Barkbox may elect to update these forward-looking statements at some point in the future, Northern Star and Barkbox specifically disclaim any obligation to do so. These forward-looking statements should not be relied upon as representing Northern Star's and Barkbox's assessments as of any date subsequent to the date of this Presentation. Accordingly, undue reliance should not be placed upon the forward-looking statements. Use of Data The data contained herein is derived from various internal and external sources.

Use of Projections The projections, estimates and targets in this Presentation are forward-looking statements that are based on assumptions that are inherently subject to significant uncertainties and contingencies, many of which are beyond Northern Star's and Barkbox's control. While all projections, estimates and targets are necessarily speculative, Northern Star and Barkbox believe that the preparation of prospective financial information involves increasingly higher levels of uncertainty the further out the projection, estimate or target extends from the date of preparation. The assumptions and estimates underlying the projected, expected or target results are inherently uncertain and are subject to a wide variety of significant business, economic, regulatory and competitive risks and uncertainties that could cause actual results to differ materially from those contained in such projections, estimates and targets. The inclusion of projections, estimates and targets in this presentation should not be regarded as an indication that Northern Star and Barkbox, or their representatives, considered or consider the financial projections, estimates and targets to be a reliable prediction of future events. 2
