Legal Information Forward-looking statements This presentation contains forward-looking statements that are subject to risks, uncertainties and other factors that could cause actual results to differ materially from those referred to in the forward-looking statements. All statements other than statements of historical fact (including statements containing the words “believes,” “plans,” “anticipates,” “expects,” “estimates” and similar expressions) are statements that could be deemed forward-looking statements, although not all forward-looking statements contain these identifying words. Readers should not place undue reliance on these forward-looking statements. Forward-looking statements may include statements regarding the expected timing of the closing of the merger; the ability of the parties to complete the merger considering the various closing conditions; the expected benefits of the merger, including estimations of anticipated cost savings and cash runway; the competitive ability and position of the combined company; the success, cost and timing of the combined company's product development, sales and marketing, and research and development activities; the combined company's ability to obtain and maintain regulatory approval for its products; the sufficiency of the combined company's cash, cash equivalents and short-term investments to fund operations; and any assumptions underlying any of the foregoing. Statements regarding future events are based on the parties’ current expectations and are necessarily subject to associated risks related to, among other things(i) the risk that the merger may not be completed in a timely manner or at all, which may adversely affect Standard BioTools' and SomaLogic's businesses and the price of their respective securities; (ii) uncertainties as to the timing of the consummation of the merger and the potential failure to satisfy the conditions to the consummation of the merger, including obtaining stockholder and regulatory approvals; (iii) the merger may involve unexpected costs, liabilities or delays; (iv) the effect of the announcement, pendency or completion of the merger on the ability of Standard BioTools or SomaLogic to retain and hire key personnel and maintain relationships with customers, suppliers and others with whom Standard BioTools or SomaLogic does business, or on Standard BioTools' or SomaLogic's operating results and business generally; (v) Standard BioTools' or SomaLogic's respective businesses may suffer as a result of uncertainty surrounding the merger and disruption of management's attention due to the merger; (vi) the outcome of any legal proceedings related to the merger or otherwise, or the impact of the merger thereupon; (vii) Standard BioTools or SomaLogic may be adversely affected by other economic, business and/or competitive factors, (viii) the occurrence of any event, change or other circumstances that could give rise to the termination of the merger agreement and the merger; (ix) restrictions during the pendency of the merger that may impact Standard BioTools' or SomaLogic's ability to pursue certain business opportunities or strategic transactions; (x) the risk that Standard BioTools or SomaLogic may be unable to obtain governmental and regulatory approvals required for the merger, or that required governmental and regulatory approvals may delay the consummation of the merger or result in the imposition of conditions that could reduce the anticipated benefits from the merger or cause the parties to abandon the Merger; (xi) risks that the anticipated benefits of the merger or other commercial opportunities may otherwise not be fully realized or may take longer to realize than expected; (xii) the impact of legislative, regulatory, economic, competitive and technological changes; (xiii) risks relating to the value of the Standard BioTools shares to be issued in the merger; (xiv) the risk that post-closing integration of the merger may not occur as anticipated or the combined company may not be able to achieve the benefits expected from the merger, as well as the risk of potential delays, challenges and expenses associated with integrating the combined company's existing businesses; (xv) exposure to inflation, currency rate and interest rate fluctuations, as well as fluctuations in the market price of Standard BioTools' and SomaLogic's traded securities; (xvi) the lingering effects of the COVID-19 pandemic on Standard BioTools' and SomaLogic's industry and individual companies, including on counterparties, the supply chain, the execution of research and development programs, access to financing and the allocation of government resources; (xvii) the ability of Standard BioTools or SomaLogic to protect and enforce intellectual property rights; and (xviii) the unpredictability and severity of catastrophic events, including, but not limited to, acts of terrorism or outbreak of war or hostilities, as well as Standard BioTools' and SomaLogic's response to any of the aforementioned factors. Therefore, actual results may differ materially and adversely from those expressed in any forward-looking statements.

Legal Information 3 Non-GAAP financial information This presentation includes certain financial information in accordance with U.S. GAAP and also on a non-GAAP basis for the three-month periods ended June 30, 2023 and June 30, 2022, and for the fiscal years ended December 31, 2021 and 2022. Management believes that non-GAAP financial measures, taken in conjunction with GAAP financial measures, provide useful information for both management and investors by excluding certain non-cash and other expenses that are not indicative of the company’s core operating results. Management uses non-GAAP measures to compare the company’s performance relative to forecasts and strategic plans and to benchmark the company’s performance externally against competitors. The time and amount of certain material items needed to estimate non-GAAP financial measures are inherently unpredictable or outside of our control. Material changes to any of these items could have a significant effect on guidance and future GAAP results. Non-GAAP information is not prepared under a comprehensive set of accounting rules and should only be used to supplement an understanding of the company’s operating results as reported under U.S. GAAP. Standard BioTools encourages investors to carefully consider its results under GAAP, as well as its supplemental non-GAAP information and the reconciliation between these presentations, to more fully understand its business. We have not reconciled our non-GAAP gross margin and adjusted EBITDA for 2023E PF and 2026E PF because certain items that impact these figures are uncertain or out of our control and cannot be reasonably predicted.
