⁽¹⁾ Adjusted gross profit, adjusted gross margin, adjusted net loss and adjusted EBITDA are non-GAAP financial measures. For a reconciliation to the most directly comparable GAAP measure, please refer to the "Reconciliation of GAAP to non-GAAP measures" section included in this press release.

Full Year 2023 Financial Outlook

Science 37 is providing updated revenue guidance of between $58.0 million and $59.0 million and adjusted EBITDA guidance of approximately $(32.5) million for the fiscal year ending December 31, 2023.

Science 37 anticipates cash burn in the fourth quarter of 2023 to be less than $6.4 million, and expects to exit 2023 with more than $50.0 million of cash on hand.

The foregoing 2023 Financial Outlook statement represents management's current estimates as of the date of this release. Actual results may differ materially depending on a number of factors. Investors are urged to read the Cautionary Note Regarding Forward-Looking Statements included in this release. Management does not assume any obligation to update these estimates.

Science 37 has not provided a quantitative reconciliation of adjusted EBITDA guidance to net income (loss) on a forward-looking basis within this press release because the Company is unable, without unreasonable efforts, to provide reconciling information with respect to interest income, depreciation, amortization, stock-based compensation, restructuring costs, change in fair value of the earn-out liability, and other adjustments to adjusted EBITDA. These items, which could materially affect the computation of forward-looking GAAP net income (loss), are inherently uncertain and depend on various factors, some of which are outside of the Science 37’s control.

This press release contains certain forward-looking statements within the meaning of the federal securities laws, including statements regarding Science 37’s anticipated growth and profitability, the products offered by Science 37 and the markets in which it operates and revenue, adjusted EBITDA and expected cash burn guidance for fiscal year 2023. These forward-looking statements generally are identified by the words “believe,” “can,” “could,” “seek,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “plan,” “position,” “may,” “might,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result” and similar expressions. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors, some of which are outside Science 37's control, could cause actual future events to differ materially from the forward-looking statements in this press release, including, but not limited to: (i) the ability to maintain the listing of Science 37’s securities on The Nasdaq Stock Market LLC, (ii) volatility in the price of Science 37’s securities due to a variety of factors, including changes in the competitive and highly regulated industries in which Science 37 operates, variations in performance across competitors, changes in laws and regulations affecting Science 37’s business and changes in its capital structure, and general economic and financial market conditions, including fluctuations in currency exchange rates, economic instability, and inflationary conditions, (iii) the ability to implement business plans, forecasts, and other expectations, and to identify and realize additional opportunities, (iv) the risk that Science 37 may never achieve or sustain profitability, (v) the risk that Science 37 will need to raise additional capital to execute its business plan, which may not be available on acceptable terms or at all, (vi) failure to realize anticipated cost savings, and (vii) risks related to general economic and financial market conditions, including the possibility of an economic recession and geopolitical conditions. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in the “Risk Factors” section of Science 37's Annual Report on Form 10-K for the fiscal year ended December 31, 2022 filed with the U.S. Securities and Exchange Commission (the “SEC”) on March 6, 2023 and in the other documents filed by Science 37 from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and Science 37 assumes no obligation and does not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law. Science 37 does not give any assurance that Science 37 will achieve its expectations.

Use of Non-GAAP Financial Measures and Key Performance Measures

In addition to the financial measures prepared in accordance with U.S. Generally Accepted Accounting Principles ("GAAP"), this press release contains certain non-GAAP financial measures, including adjusted gross profit, adjusted gross margin, adjusted EBITDA and adjusted net income (loss). A “non-GAAP financial measure” is generally defined as a numerical measure of a company’s financial performance that excludes or includes amounts from the most directly comparable measure calculated and presented in accordance with GAAP in the statements of operations, balance sheets, or statements of cash flows of the Company. Please refer to the reconciliations of the non-GAAP financial measures to their most directly comparable GAAP measures included in this press release and the accompanying tables contained at the end of this release.

The Company defines adjusted gross profit as gross profit excluding stock-based compensation expense. The Company defines adjusted gross margin as gross margin excluding stock-based compensation expense.

The Company defines adjusted net income (loss) as net income (loss) excluding transactions that the Company believes are not representative of its core operations, namely: restructuring and other costs; transaction and integration-related expenses; stock-based compensation expense; impairment losses; interest income; other income (expense), net; and gain or loss on extinguishment of debt.

EBITDA represents earnings before interest, taxes, depreciation, and amortization. The Company defines adjusted EBITDA as EBITDA, further adjusted to exclude expenses and transactions that the Company believes are not representative of its core operations, namely: restructuring and other costs; transaction and integration-related expenses; stock-based compensation expense; impairment losses; other income (expense), net; and gain or loss on extinguishment of debt.

Each of the non-GAAP measures noted above are used by management and the Board to evaluate the Company's core operating results because they exclude certain items for which fluctuations from period-to-period do not necessarily correspond to changes in the core operations of the business.

Management believes that adjusted gross profit, adjusted gross margin, adjusted EBITDA and adjusted net income (loss) are helpful to investors, analysts, and other interested parties because they can assist in providing a more consistent and comparable overview of our operations across our historical periods. In addition, these measures are frequently used by analysts, investors, and other interested parties to evaluate and assess performance.

Non-GAAP measures have limitations in that they do not reflect all of the amounts associated with the Company's results of operations as determined in accordance with GAAP. Also, other companies might calculate these measures differently.

This press release also contains certain key performance measures which we use to evaluate our business and results, measure performance, identify trends, formulate plans and make strategic decisions. We believe that the presentation of such metrics is useful to the Company’s investors because they are used to measure and model the performance of companies such as ours. Net bookings represent new business awards, net of contract modifications, contract cancellations, and other adjustments. Net bookings represent the minimum contractual value for the initial planned duration of a contract as of the contract execution date. The minimum fixed fees, upfront implementation fees and technology and support fees are included in net bookings. Estimates of variable revenue for utilization in excess of the contracted amounts are not included in the value of net bookings. Net bookings vary from period to period depending on numerous factors, including customer authorization volume, sales performance and the overall outlook of the life sciences industry, among others.
