3 Century Therapeutics: Building an industry - leading, next - generation allogeneic iPSC - derived cell therapy platform LIMITLESS POTENTIAL… PRECISION DESIGN… ENDURING IMPACT… Foundational investments in iPSC technology, genetic editing, protein engineering, and manufacturing Progressing differentiated clinical programs based on Allo - Evasion TM technology in oncology and autoimmune and inflammatory diseases Well - capitalized into 2026 to enable delivery on key milestones and clinical data



Overview of Foundational Platform Technologies



5 Century’s singular focus: To deliver best - in - class iPSC - derived cell therapies Century platform enables the incorporation of critical features we b elieve can only be realized via iPSC - derived cell therapies Infinite replicative capacity at the iPSC stage enables potentially unlimited genomic editing via CRISPR HDR Single cell cloning of engineered iPSC allows selection of a fully characterized clone for a master cell bank, ensuring safety and functional reproducibility of the final drug product Production from a master cell bank – derived from a single donor – enables larger batch sizes and lower cost of goods than donor - derived or autologous Platform capable of fully leveraging multiple advances in synthetic biology into a single product Differentiation conditions developed for generating multiple immune effector cells , including NK cells, CD4+ T cells (Th and Treg), CD8+ T cells, monocytes / macrop hages Cell expansion during multiple stages of differentiation yields large cell harvests, decreasing risk of cell exhaustion, reducing COGs and providing robust drug inventory that is potentially infinitely replenishable



6 Century’s next - generation allogeneic iPSC technology platform: Versatility and unprecedented control Rapid Integration of major advances in product functionality and manufacturability iPSC iT cell iNK cell SINGLE CELL CLONING POST GENE EDITING AND CHARACTERIZATION DIFFERENTIATION Consistency Yield Fitness: No exhaustion Allo - Evasion TM Homeostasis/ persistence Modulation of TME Safety switch Integration of advances in synthetic biology Product design Manufacturing Engineered iPSC MCB



7 Precision CRISPR MAD7 mediated sequential gene editing of iPSC cells generates uniform product candidates Multiple gene edits (KO/KI) iPSC bank Engineered iPSC Master Cell Bank (MCB) Sequential selection steps iSPC Precision Engineering CRISPR - mediated HDR (MAD 7) Advantages of Century’s Platform Precise CRISPR mediated homology directed repair reduces off - target integration Stepwise and efficient gene editing avoids risky multiplex modification and structural variants Quality control through generation of homogenous MCB establishes genomic product integrity Manufacturing begins at the MCB, confirmed to be free from genetic aberrations



8 Allo - Evasion TM edits + repeat dosing = potential greater durability Potential to drive durable responses with engineering to resist immune rejection Next - wave of allogeneic cell therapies must solve for challenge of rejection With Allo - Evasion TM engineering Without Allo - Evasion TM engineering



9 Advancing our leadership in Allo - Evasion TM technology Continuous improvement in holistic immune protection designed to overcome major pathways of host vs. graft rejection Allo - Evasion TM 1.0 Allo - Evasion TM 3.0 Allo - Evasion TM 5.0 b 2M KO (HLA - I) CIITA KO (HLA - II) CD8 + T Cell CD4 + T Cell Pan NK Inhibitory ligand Fc NK cell 1 2 Core edits disarm host cells from eliminating therapy Deletion of β 2M, a protein required to express HLA - 1 on the cell surface prevents recognition by CD8 T cells Knock out of CIITA eliminates HLA - II expression to escape elimination by CD4 T cells Knock - in of HLA - E prevents killing by NK cells Allo - Evasion TM 1.0 edits plus the incorporation of: Knock - in of HLA - G improves protection against killing by NK cells Deletion of β 2M, a protein required to express HLA - 1 on the cell surface prevents recognition by CD8 T cells Knock out of CIITA eliminates HLA - II expression to escape elimination by CD4 T cells Pan - NK inhibitory ligand to provide broader protection against killing by NK cells IgG degrading protease designed to protect against humoral immunity



10 Foundational investments in iPSC manufacturing Established in - house manufacturing Developing fit - for - purpose products • Century 53,000 ft 2 GMP facility • Designed to produce multiple immune cell types • Accelerates learnings and enables faster product iteration • Two sites (FCDI GMP manufacturing, Century in - house manufacturing) provide optionality and maximizes flexibility • Increased process and product consistency • Scalable platforms and optimized processes to maximize yield, reduce COGs, and meet demand • Increased cell fitness, as cells do not undergo excessive expansion cycles which often result in cell exhaustion • Homogeneity of the manufacturing process produces a product candidate that can be readily characterized

22 Allo - Evasion TM edits + repeat dosing without the need for LD With Allo - Evasion TM engineering Without Allo - Evasion TM engineering Allo - Evasion TM enables repeat dosing without the need for continued lymphodepletion Initial clinical evidence indicates no sign of allo - rejection for CNTY - 101 (ASH case study) Allo - Evasion TM provides potential to more tightly control drug exposure to enable sustained pressure on the target CNTY - 101 cells persist in tissues for at least 3 days as measured by cfDNA; observed with and without LD Clinical patient case from Ph1 ELiPSE - 1 trial. Detectable signal [+] was determined to be significantly above negative controls using two sample Poisson test, p < 0.05; transgene copies detected in 1 mL of plasma is indicated Anti - drug antibodies and functional humoral immune response against CNTY - 101 are not detected (seven cycles evaluated) ADCC CDC ELiPSE - 1 Clinical Data No LD ADCC: Antibody - dependent cellular cytotoxicity CDC: Complement dependent cytotoxicity

24 Key differentiators of CNTY - 101 in autoimmune disease treatment CNTY - 101: CD - 19 targeted iNK cell therapy with 6 precision gene edits including Allo - Evasion TM technology • Currently being studied in Ph1 ELiPSE - 1 trial in R/R NHL • Ph1 CALiPSO - 1 trial in SLE initiating in early 3Q 2024 Key differentiators in AID: (1) Allogeneic (2) NK cells (3) Allo - Evasion TM NK cells Allogeneic Allo - Evasion TM • Killing potency ≥ primary CAR - T • Trafficking to secondary lymphoid tissues and marrow favors pathogenic B - cell targeting • Limited in vivo expansion • Available “off - the - shelf” • No patient apheresis required • No manufacturing wait time • Platform enables lower COGs than donor - derived or autologous • Avoiding host immune rejection • Ability to repeat dose without continued lymphodepletion • Ability to retreat, if needed Tighter control over drug exposure: B - cell depletion without prolonged B - cell aplasia



25 CNTY - 101: Potential to drive B - cell depletion with tighter control over drug exposure More potent than primary CAR - T at B - cell killing in preclinical comparison CNTY - 101 more potent than primary CAR - T cells at B - cell killing at 24 hours in preclinical comparison Isolated B cells or CD19+ target cells were co - cultured with CNTY - 101 or primary CAR - T at several E:Ts in 96 - well U bottom plate s in NKCM with assay harvested at 24h. Assay plates were harvested and stained for Fixable Live/Dead. Cells were fixed and run on cytometer to determine Target+Dead Cell populations.
