Forward Looking Statements This presentation includes “forward-looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. The actual results of the Company may differ from its expectations, estimates, and projections and, consequently, you should not rely on these forward-looking statements as predictions of future events. Words such as “expect,” “estimate,” “project,” “budget,” “forecast,” “anticipate,” “intend,” “plan,” “may,” “will,” “could,” “should,” “believes,” “predicts,” “potential,” “continue,” and similar expressions (or the negative versions of such words or expressions) are intended to identify such forward-looking statements. These forward-looking statements include, without limitation, the Company’s expectations with respect to future performance and development and commercialization of products and services, its anticipated cash runway and its financial guidance for the full year 2024. These forward-looking statements involve significant risks and uncertainties that could cause the actual results to differ materially from those discussed in the forward-looking statements. Most of these factors are outside the Company’s control and are difficult to predict. Factors that may cause such differences include, but are not limited to: the inability to maintain the listing of the Company’s Class A common stock on The Nasdaq Stock Market; the ability of the Company to grow and manage growth profitably and retain its key employees; the Company’s ongoing leadership transitions; changes in applicable laws or regulations; the ability of the Company to raise financing in the future; the success, cost and timing of the Company’s product development and commercialization activities; the commercialization and adoption of the Company’s existing products and the success of any product the Company may offer in the future; the potential attributes and benefits of the Company’s commercialized Platinum® protein sequencing instrument and kits and the Company’s other products once commercialized; the Company’s ability to obtain and maintain regulatory approval for its products, and any related restrictions and limitations of any approved product; the Company’s ability to identify, in-license or acquire additional technology; the Company’s ability to maintain its existing lease, license, manufacture and supply agreements; the Company’s ability to compete with other companies currently marketing or engaged in the development or commercialization of products and services that serve customers engaged in proteomic analysis, many of which have greater financial and marketing resources than the Company; the size and growth potential of the markets for the Company’s products and services, and its ability to serve those markets once commercialized, either alone or in partnership with others; the Company’s estimates regarding future expenses, future revenue, capital requirements and needs for additional financing; the Company’s financial performance; and other risks and uncertainties described under “Risk Factors” in the Company’s most recent Annual Report on Form 10-K and Quarterly Reports on Form 10-Q and in the Company’s other filings with the SEC. The Company cautions that the foregoing list of factors is not exclusive. The Company cautions readers not to place undue reliance upon any forward-looking statements, which speak only as of the date made. The Company does not undertake or accept any obligation or undertaking to release publicly any updates or revisions to any forward-looking statements to reflect any change in its expectations or any change in events, conditions, or circumstances on which any such statement is based.

Rationale for New Technology Architecture Semiconductors require large R&D investment Re-partitioning of system allows for less expensive consumable Leverage optical magnification to pack wells closer together and scale to billions of reads Leverage high-performance, commercially-available imaging components Liquid Sample Reaction Chambers Fused Silica Wafer Imaging System

QSI Core Technologies Trying to show all components of core tech. Do not need “chip” box and SW image could be something else Chip Surface Chemistry Instrument Library Prep + Sequencing Reagents Software

Chip + Surface Chemistry Simple passive device with approximately 20M wells (per flow cell) at initial launch Heavily de-risked — leverages existing design, materials, and fabrication methods Compatible with existing surface chemistry Surface passivation Functionalized well bottom

Proteus™ Consumable Development Wafer process flow developed in production foundry Prototype wafers fabricated and tested Simple process has low-risk path to high-volume production

Proteus™ Instrument Development Move imaging components to the system Increase workflow automation Leverage commercially available technologies for imaging and liquid handling Takes advantage of significant investment in optics driven by NGS industry

Library Prep + Sequencing Chemistry Existing library prep and sequencing chemistry are completely portable New system discriminates dyes with color rather than lifetime Some new dye development is necessary, but is underway and low risk

Color Ratio is a Viable Alternative to Current Lifetime Detection Key elements have already been de-risked Move to color means we can leverage off-the-shelf camera technology

Brian Reed Innovation Toward the Most Advanced Set of Discovery Applications in Proteomics

Agenda Innovation at the Forefront of Proteomics The path to complete proteome coverage 1 Deep, unbiased interrogation of high-complexity samples 3 Beyond sequencing: the first platform for top-down single-molecule proteomics 4 Ultrasensitive PTM detection for proteoforms 2

Acceleration on the Path to Complete Proteome Coverage

Sequence Proteins on Platinum Each recognizer binds 1-3 cognate N-terminal amino acids (NAAs) Rapid on-off binding generates a pulsing pattern detected by the chip Extremely information-rich data output: 10s-100s of pulsing events per amino acid

A Rapid Path to Complete Amino Acid Coverage Our team has mastered the engineering and evolution of amino acid recognizers As a result of our rich kinetic output, we have more data on our recognizers than possibly any other set of proteins in biotechnology Recognizers in the V3 kit recognize 13 of the 20 types of amino acids (69%) New recognizers have already been developed and are on track for release in our next kit update We are on track to enable complete reference-free sequencing: enables key applications like sequencing antibodies and cancer neoantigens de novo

Kinetic Signatures are Sensitive to Downstream Sequence Recognizers physically contact residues downstream of bound NAA Influence is encoded in the peptide’s kinetic signature and is highly predictable Kinetic signatures are a unique and powerful feature of Quantum-Si's core technology The acquisition of single-molecule kinetic information gives us unprecedented insight into binding interactions PD = 2.4s PD = 0.96s

Ultrasensitive PTM Detection for Proteins and Proteoforms

Phosphorylation is the Most Abundant PTM in the Human Proteome Post-translational modifications (PTMs) are central to protein function and implicated in human diseases There are more than 400 different types of PTMs; phosphorylation is the dominant type (~72% of all PTM sites) Phosphorylation has the largest disease association: 81% of all discovered PTM-associated diseases1 https://doi.org/10.1016/j.gpb.2018.06.004 Nat Chem Biol 14, 206–214 (2018). https://doi.org/10.1038/nchembio.2576

Affinity Reagents as Ultrasensitive PTM Recognizers Anti-PTM antibodies and other affinity reagents work on chip for ultrasensitive PTM detection Deliver the same real-time kinetic information as NAA recognizers Recognize PTMs anywhere in the peptide (not just at the N-terminus) PTM Recognition AQRYLAYPD AQRYLAYPD Anti-pY antibody Phosphotyrosine

Phosphotyrosine Affinity Reagents as Ultrasensitive PTM Recognizers 30 min Step1: PTM detection for 30 minutes with PTM recognizer Step 2: Normal protein sequencing with NAA recognizers PTM recogizers can be multiplexed and combined with kinetic signatures to pinpoint PTMs in multisite configurations Step 1: PTM recognition Step 2: Sequencing E F L N R F

Ultrasensitive Phosphotyrosine Detection with CDNF Extreme sensitivity to PTM stoichiometry due to the clear pulsing pattern from PTM recognition Example: a CDNF peptide is detected at a ratio of less than 1 phosphorylated peptide in 1,000 Method can be extended to other types of PTMs, e.g., ubiquitination, glycosylation; works with commercially available affinity reagents CDNF_HUMAN ..QEAGGRPGADCEVCK EFLNRFYK SLIDRGVNFSLDTIEK ELISFCLDTK.. Detection of less than 1 PTM-modified peptide in 1,000 pY-modified peptide Unmodified peptide PTM recognition Sequencing

Recognition of Human TAU Proteoforms Affinity reagents can be used in a bottom-up or top-down configuration Example: bottom-up recognition of pT* on human TAU peptides, top-down detection of immobilized full-length TAU proteoforms Real-time approach enables proteoform detecting reagents to be run simultaneously First commercially available platform for detection and differentiation of full-length proteoforms Phosphothreonine TAU_HUMAN ..VAVVRTPPKSPSSAK SRLQTAPVPMPDLK NVK SK IGSTENLK HQPGGGK VQIINK K.. Full-length TAU PTM recognition Sequencing Single-molecule TAU proteoform detection * - Phosphothreonine

Unbiased Interrogation of High-Complexity Samples with Quantum-Si's Core Technology

Sequencing Complex Biological Samples Unlocks Broad Access to Proteomics PROTEIN CONTENT COMPLEXITY Protein complexes Viral particles Sub- cellular protein fractions Plasma extra- cellular vesicles Serum/ plasma Cell lysates Tumor tissue samples Cerebro- spinal fluid 1,000s 100s 10s Biological samples like serum contain hundreds to thousands of proteins with wide dynamic range of abundance Unbiased, consistent, accessible interrogation of these samples is a challenge in proteomics Sequencing is not limited to predefined content: enables discovery of changes in proteins and proteoforms that other methods are unable to access

Unbiased Interrogation of High-Complexity Samples New chip architectures and advances in sequencing chemistry will enable sequencing biological samples at ever-increasing depth Future versions of the platform will see shotgun sequencing with thousands of proteins identified Barcoding approaches and flowcell designs will enable sample multiplexing Innovative methods to fractionate proteins and to reduce sample complexity will be combined with these improvements Platinum (2M) ProteusTM 1.0 (50M+) ProteusTM 2.0 (10B)

Fast Sequencing for Deep Coverage and Rapid Sample-to-Answer Standard chemistry FAST chemistry v1 Example peptide We have developed new sequencing chemistry with a much faster rate of sequencing With FAST chemistry, we achieve equal performance to 10-hour runs in just 90 minutes (version 1) Path to runs <30 minutes for some applications with further development Enables deep sample coverage via iterative FAST sequencing and rapid sample-to-answer methods for clinical applications

Beyond Sequencing: the First Commercially Available Platform for Top-Down Single-Molecule Proteomics

Dye-cycling enables ultrasensitive real-time detection of biomarkers Detecting Antibody Binding Events with the Power of Real-Time Kinetics IL6 Capture antibody Detection antibody Detection of fixed protein panels with high sensitivity is an increasingly important application in proteomics We developed a single-molecule sandwich assay that enables real-time detection of biomarkers Dye-cycling approach uses our existing kits to translate immune complex formation into a readily detected pulsing segment Antigen capture Antigen release

Ultrasensitive Detection of Proteins in Serum Interleukin 6 Lysozyme GFP Spike-in titration experiments in serum demonstrate 0.1–1 pg/mL detection (path down to 10 fg/mL with further development) Direct detection of proteins in serum with high sensitivity

Multiplexed Ultrasensitive Protein Biomarker Detection Affinity reagents against multiple biomarkers can be loaded on the chip Dye-cycling approach enables discrimination of biomarkers by fluorescence and kinetic properties in multiplexed assays, along with PTMs IL6 TNF-α Multiplexed detection of human IL6 and TNF-α

A Platform for Ultrasensitive Detection of Protein Panels Sensitivity on Platinum is suitable for commercialization of panels with up to 10 proteins Panel size scales with the platform, as well as capacity to multiplex samples Proteins detected directly in serum on chip, eliminating complex sample prep Sample-to-answer in ~2 hours with one instrument Protein panel size scales with the platform Multiplexed biomarker detection directly in serum IL10 IL6 IL2 IL4 TNFα IFNγ IL12 : ProteusTM 2.0 (1,000+) ProteusTM 1.0 (100’s) Platinum (up to 10)
