Interested in Adicet Bio, Inc.? Here are five stocks we like better. Adicet Bio expects to report lupus data this quarter for its off-the-shelf CAR-T candidate ADI-001, covering 22 patients with at least six months of follow-up and 13 with at least 12 months. The company aims to show 12-month complete-response rates comparable to autologous CAR-T therapies. The company is focusing initially on a potential registrational path in lupus nephritis after recent FDA discussions, while preserving the option to expand into systemic lupus erythematosus. Potential studies could use single-arm designs and assess steroid reduction, quality of life, and other measures beyond standard lupus endpoints. Adicet also plans additional pipeline updates, including systemic-sclerosis data later this year, a prostate-cancer gamma delta cell therapy, and details on an in vivo CAR-T program. Adicet Bio (NASDAQ:ACET) expects to report clinical data this quarter for its lead autoimmune program, ADI-001, also known as prula-cel, including results in lupus nephritis (LN) and systemic lupus erythematosus (SLE), Chief Executive Officer Chen Schor said at the 46th Annual Canaccord Genuity Growth Conference. ADI-001 is an off-the-shelf gamma delta 1 cell therapy targeting CD20. Schor said the company expects its upcoming LN and SLE update to include 22 enrolled patients, all with at least six months of follow-up. Thirteen of those patients are expected to have at least 12 months of follow-up, primarily in lupus nephritis. → SoundHound AI Sends a Loud Signal After Its Q2 Earnings Beat “One year seems to be the benchmark that people are looking at,” Schor said, adding that Adicet’s goal is to demonstrate a complete-response rate at 12 months comparable with rates reported for autologous CAR-T therapies. Schor said CD20 targeting has shown B-cell depletion results that appear comparable to CD19-directed approaches based on the company’s data. He said Adicet has observed complete depletion of CD19-positive B cells in blood and lymph-node biopsy samples, along with what he characterized as an immune-system reset as patients recover. → 3 Dividend Champion Utilities for a Market That Can't Sit Still He emphasized that tissue penetration, particularly B-cell depletion in lymph nodes, is important for evaluating activity in autoimmune disease. The company has not yet completed the data cut for its upcoming disclosure, he said, but expects to announce the results during the current quarter. Adicet enrolled patients across five countries and was able to recruit at centers that do not necessarily conduct cell-therapy studies, according to Schor. He attributed that enrollment flexibility to the product’s off-the-shelf availability and the lack of a need for leukapheresis, the process used to collect a patient’s cells for autologous therapies. → Is Wingstop's Growth Story Losing Steam? Following a recent meeting with the U.S. Food and Drug Administration, Adicet plans to provide regulatory feedback alongside its data update, Schor said. He indicated that the company’s initial registrational focus is expected to be lupus nephritis, reflecting the composition of its existing clinical data set, while retaining the option to later expand into SLE. According to Schor, registrational studies in LN, SLE, or a combined LN and SLE population could potentially use single-arm designs. He said study sizes in the field have ranged from approximately 35 patients in more heavily pretreated populations to roughly 90 patients in populations that have failed fewer prior therapies. Schor also discussed endpoints beyond conventional lupus measures. He said the company may evaluate factors such as physician global assessment, patient quality of life, reduced use of immunosuppressive drugs, and low or reduced steroid use. He characterized the ability to measure responses without chronic immunosuppression as a potential distinction for cell therapy relative to treatments that require ongoing therapy. Adicet also expects to report data in systemic sclerosis during the second half of the year. Schor said the company enrolled a “reasonable number” of patients in that study but did not provide additional guidance on the expected data set. In rheumatoid arthritis, Adicet is conducting a small study comparing lymphodepletion regimens using cyclophosphamide and fludarabine versus cyclophosphamide alone. Schor said the study is intended to determine whether fludarabine is needed with gamma delta CAR-T cells and could inform conditioning approaches in other indications. The company currently plans to use standard cyclophosphamide/fludarabine conditioning in its pivotal study. Beyond ADI-001, Schor said Adicet has an off-the-shelf gamma delta 1 cell therapy for prostate cancer planned for clinical development. The candidate targets prostate-specific membrane antigen, or PSMA, and incorporates two additional technologies intended to improve potency and address challenges associated with cell therapy in solid tumors. The company also plans to disclose details of an in vivo CAR-T pipeline in the near future. “There’s going to be a lot coming from us in the next few months,” Schor said.

Adicet continues to advance its ongoing Phase 1 clinical trial evaluating prula-cel across multiple autoimmune diseases. Prula-cel has received Fast Track Designation from the FDA for the potential treatment of relapsed/refractory Class III or Class IV LN, refractory SLE with extrarenal involvement, and systemic sclerosis (SSc). The next clinical update is expected in the first half of 2026, with plans to provide an additional clinical update from the study in the second half of 2026. Adicet plans to meet with the FDA in the second quarter of 2026 to inform potential pivotal trial design. Subject to regulatory clearance to proceed, the Company expects to initiate a pivotal study in LN or LN and SLE patients in the second half of 2026. Alignment with FDA allows outpatient dosing for LN and SLE patients. In November 2025, the Company reached alignment with the FDA to allow LN and SLE patients to be dosed with prula-cel in the outpatient setting in ongoing and future clinical trials. Phase 1 study underway in treatment-refractory rheumatoid arthritis (RA) patients to evaluate the potential to reduce conditioning requirements. In October 2025, Adicet dosed the first patient in a Phase 1 study of prula-cel in treatment refractory RA. The study is evaluating two lymphodepletion regimens: cyclophosphamide alone and cyclophosphamide in combination with fludarabine. The primary objective of the study is to assess the safety and tolerability of prula-cel, with secondary objectives including evaluation of cellular kinetics, pharmacodynamics, and disease activity scores. The next clinical update on this trial is expected in the second half of 2026. Solid tumor indications Preclinical development ongoing for ADI‑212, with a regulatory filing expected in the third quarter of 2026, which is expected to enable Phase 1 enrollment beginning in the fourth quarter of 2026. Adicet continues to advance preclinical development of ADI‑212, a next‑generation gene‑edited and armored cell therapy candidate targeting prostate-specific membrane antigen (PSMA). ADI‑212 is engineered to express a novel CAR binder designed to support enhanced tolerability and tumor‑specific recognition. It integrates membrane‑tethered IL‑12 armoring, and CRISPR/Cas9‑mediated disruption of subunit 12 (MED12) to enhance potency in solid tumors and deliver multiple anti‑tumor mechanisms of action within the tumor microenvironment. Adicet plans to submit a regulatory filing for ADI-212 for the treatment of mCRPC in the third quarter of 2026, with Phase 1 enrollment expected to begin in the fourth quarter of 2026, subject to regulatory clearance. ADI‑212 preclinical data presented at scientific meeting. In October 2025, Adicet presented preclinical data from its ADI‑212 program at the 32nd Annual Prostate Cancer Foundation Scientific Retreat. The data supported the rationale for the program’s design features and demonstrated functional enhancements across multiple preclinical models of disease. Financial Results for Fourth Quarter and Full Year 2025: Three months ended December 31, 2025 Research and Development (R&D) Expenses: R&D expenses were $25.0 million for the three months ended December 31, 2025, compared to $23.3 million during the same period in 2024. The increase in R&D expenses was primarily due to a $6.1 million increase in expenses related to contract research organizations (CROs) and contract development and manufacturing organizations (CDMOs), partially offset by a $2.7 million decrease in payroll and personnel expenses due to lower headcount and a $1.0 million decrease in facilities related expenses. General and Administrative (G&A) Expenses: G&A expenses were $6.9 million for the three months ended December 31, 2025, compared to $7.5 million during the same period in 2024. The decrease in G&A expenses was primarily due to a $1.3 million decrease in rent and office related expenses and a $0.7 million decrease in professional services and consultants, partially offset by a $1.6 million increase in payroll and personnel expenses primarily related to stock-based compensation. Net Loss: Net loss for the three months ended December 31, 2025 was $30.5 million, or a net loss of $2.94 per basic and diluted share, including non-cash stock-based compensation expense of $5.7 million, as compared to a net loss of $28.7 million, or a net loss of $5.06 per basic and diluted share, including non-cash stock-based compensation expense of $3.8 million during the same period in 2024. Twelve months ended December 31, 2025 Research and Development (R&D) Expenses: R&D expenses were $99.1 million for the year ended December 31, 2025, compared to $99.3 million for the year ended December 31, 2024. The decrease in R&D expenses was primarily due to a $5.1 million decrease in payroll and personnel expenses related to lower headcount and a $0.7 million decrease in lab supplies and materials. The decrease was partially offset by a $5.6 million increase in CRO costs primarily for autoimmune studies. General and Administrative (G&A) Expenses: G&A expenses were $23.0 million for the year ended December 31, 2025, compared to $28.3 million for the year ended December 31, 2024. The decrease in G&A expenses was primarily due to a decrease in payroll and personnel expenses primarily related to a decrease in stock-based compensation of $3.6 million, a $1.6 million decrease in office related expenses, and a $0.3 million decrease in rent expense. Net Loss: Net loss for the year ended December 31, 2025 was $116.8 million, or a net loss of $16.95 per basic and diluted share, including non-cash stock-based compensation expense of $14.3 million, as compared to a net loss of $117.1 million, or a net loss of $21.33 per basic and diluted share, including non-cash stock-based compensation expense of $22.2 million during the same period in 2024. Cash Position: Cash, cash equivalents and short-term investments were $158.5 million as of December 31, 2025, compared to $176.3 million as of December 31, 2024. In October 2025, Adicet successfully raised $74.8 million in net proceeds through an underwritten registered direct offering of equity securities. The Company expects that current cash, cash equivalents and short-term investments as of December 31, 2025, will be sufficient to fund its operating expenses into the second half of 2027.

In addition to revenue, management regularly reviews key business metrics to evaluate our business, measure performance, identify trends affecting our business, formulate financial projections and make strategic decisions. As of the dates presented, these key metrics were as follows: Third Quarter 2025 Financial Results Total revenue for the third quarter of 2025 was $6.8 million, compared to $8.2 million in the third quarter of 2024, representing a decrease of 16%. Core business revenue (sales of instruments, PAs and consumables, assay services, and licenses to customers, excluding SPL Program-related revenue) for the third quarter of 2025 was $6.4 million, compared to $8.1 million in the third quarter of 2024, representing a decrease of 21%. SPL Program-related revenue was $0.4 million in the third quarter of 2025, as compared to immaterial in the third quarter of 2024. Gross profit for the third quarter of 2025 was $5.2 million (77% gross margin), compared to $6.2 million (76% gross margin) in the third quarter of 2024. Non-GAAP adjusted gross margin was 81% excluding SPL Program-related revenue and reserves for excess and obsolete inventory, compared to non-GAAP adjusted gross margin of 85% in the third quarter of 2024. Operating expenses for the third quarter of 2025 were $19.4 million, compared to operating expenses of $20.3 million in the third quarter of 2024. Third quarter 2025 net loss was $12.4 million compared to net loss of $11.6 million for the same period in 2024. Adjusted EBITDA, a non-GAAP measure, was a loss of $10.0 million for the third quarter of 2025, compared to a loss of $13.0 million for the third quarter of 2024; stock-based compensation expense was $2.0 million in the third quarter of 2025 compared to $3.4 million in the third quarter of 2024. 2025 Guidance MaxCyte reiterates 2025 revenue guidance for core business revenue and SPL Program-related revenue: Core revenue is expected to be flat to a 10% decline compared to 2024, inclusive of revenue from SeQure Dx. SPL Program-related revenue is expected to be approximately $5 million for the year. SPL-program related revenue guidance includes both expected revenue from pre-commercial milestone payments and commercial royalties/sales-based payments. MaxCyte expects to end 2025 with $152 million to $155 million in total cash, cash equivalents and investments.

Non-GAAP Financial Measures This press release contains EBITDA, which is a non-GAAP measure defined as earnings before interest income and expense, taxes, depreciation and amortization. This press release also contains Adjusted EBITDA, which is a non-GAAP measure defined as earnings before interest, taxes, depreciation, amortization and one-time restructuring charges. MaxCyte believes that EBITDA and Adjusted EBITDA provide useful information to management and investors relating to its results of operations. The company’s management uses these non-GAAP measures to compare the company’s performance to that of prior periods for trend analyses, and for budgeting and planning purposes. The company believes that the use of EBITDA and Adjusted EBITDA provide an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing the company’s financial measures with other companies, many of which present similar non-GAAP financial measures to investors, and that it allows for greater transparency with respect to key metrics used by management in its financial and operational decision-making. This press release also contains Non-GAAP Gross Margin, which we define as Gross Margin when excluding SPL program related revenue and reserves for excess and obsolete inventory. The Company believes that the use of Non-GAAP Gross Margin provides an additional tool to investors because it provides consistency and comparability with past financial performance, as Non-GAAP Gross Margin excludes non-core revenues and inventory reserves, which can vary significantly between periods and thus affect comparability. Management does not consider these Non-GAAP financial measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these Non-GAAP financial measures is that they exclude significant revenues and expenses that are required by GAAP to be recorded in the Company’s financial statements. In order to compensate for these limitations, management presents these Non-GAAP financial measures along with GAAP results. Non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. Reconciliation tables of net loss, the most comparable GAAP financial measure, to EBITDA and Adjusted EBITDA, and Gross Margin, the most comparable GAAP financial measure, to Non-GAAP Gross Margin, are included at the end of this release. MaxCyte urges investors to review the reconciliation and not to rely on any single financial measure to evaluate the company’s business Forward-Looking Statements This press release contains "forward-looking statements" within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995.

Third Quarter 2025 and Recent Operational Highlights: Autoimmune diseases Announced positive preliminary data in LN and SLE patients from Phase 1 study of ADI-001 in autoimmune diseases. In October 2025, Adicet announced positive initial safety and efficacy data from seven patients (five LN and two SLE patients) dosed with ADI-001 in the ongoing Phase 1 trial, with follow-up ranging from two to nine months as of the August 31, 2025 data cut-off date. All patients demonstrated rapid and sustained reductions in the SLEDAI-2K score and PGA. All patients in the LN cohort achieved improved renal function, including three complete renal responses and Definition of Remission In Systemic lupus erythematosus (DORIS) remissions, and two partial responses. ADI-001 also demonstrated multiple hallmarks of immune reset with subsequent emergence of naïve and previously undetected B cell repertoire following single dose treatment. ADI-001 was generally well tolerated and demonstrated a favorable safety profile, with no Grade 2 or higher Cytokine Release Syndrome (CRS), and no cases of Immune Effector Cell-Associated Neurotoxicity Syndrome (ICANS) observed. Based on these results, the Company plans to request a meeting with the FDA in the first quarter of 2026 to inform potential Phase 2 pivotal trial design, with the initiation of the study in LN or LN and SLE patients anticipated to commence in the second quarter of 2026. Enrollment ongoing in ADI-001 Phase 1 program. Adicet is actively enrolling patients in its Phase 1 clinical trial evaluating ADI-001 in autoimmune diseases which include: LN, SLE, SSc, IIM, SPS and AAV. Adicet expects to provide an LN and SLE clinical update as well as an SSc clinical update in the first half of 2026. Actively enrolling patients with treatment-refractory RA in Phase 1 study of ADI-001 evaluating potential to reduce the need for conditioning. The Company is enrolling patients with treatment-refractory RA in a Phase 1 study of ADI-001 evaluating two lymphodepletion regimens: cyclophosphamide alone and cyclophosphamide with fludarabine. Adicet expects to provide a clinical update on the Phase 1 trial in the second half of 2026. Solid tumor indications Presented ADI-212 preclinical data at the 32nd annual Prostate Cancer Foundation Scientific Retreat. Adicet is continuing to advance preclinical development of ADI-212, an optimized next-generation gene-edited and armored clinical candidate designed to target PSMA. ADI-212 is engineered to express a novel CAR binder designed to support enhanced tolerability and tumor-specific recognition. It integrates membrane-tethered IL-12 (mbIL-12) armoring and CRISPR/Cas9 mediated disruption of subunit 12 of the mediator complex (MED12) to enhance potency in solid tumors and deliver multiple anti-tumor mechanisms of action within the tumor microenvironment. In October, Adicet presented preclinical data at the 32nd Annual Prostate Cancer Foundation Scientific Retreat supporting these design elements and functional enhancements in multiple models of disease. Regulatory filing on track for ADI-212 in mCRPC. Adicet plans to submit a regulatory filing for ADI-212 for the treatment of mCRPC in the first quarter of 2026. The Company expects to share initial clinical data from the ADI-212 program in the second half of 2026, subject to regulatory clearance to proceed with a clinical trial. Corporate updates Raised $74.8 million in net proceeds in registered direct offering. In October 2025, Adicet successfully raised $74.8 million in net proceeds through an underwritten registered direct offering of equity securities, extending its cash runway into the second half of 2027. Financial Results for Third Quarter 2025: Research and Development (R&D) Expenses: R&D expenses were $22.9 million for the three months ended September 30, 2025, compared to $26.3 million during the same period in 2024.

(Nasdaq: ACET), a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for autoimmune diseases and cancer, today reported financial results and operational highlights for the second quarter ended June 30, 2025. "We continue to make meaningful progress in our ADI-001 autoimmune Phase 1 clinical program. Site activation is progressing well with more than 20 sites currently open for enrollment in multiple territories and additional sites on track to open in the next few months. We see increased interest by investigators and patients in ADI-001 as a well-tolerated, off the shelf, one-time potential therapy for patients with autoimmune diseases. Enrollment is gathering momentum and we remain on track to share preliminary Phase 1 data for the program in the second half of 2025, with at least 6 patients with at least 3 months’ follow-up, which we believe will further validate the differentiated potential of our gamma delta T cell platform," said Chen Schor, President and Chief Executive Officer of Adicet Bio. "In addition, we have recently conducted a strategic review of our pipeline to focus our resources on programs with the greatest potential for long-term clinical and commercial value. As such, we are prioritizing the preclinical development of ADI-212, a gene-edited and armored clinical candidate designed to enhance potency in solid tumors and to deliver multiple anti-tumor mechanisms of action to the tumor microenvironment. Our commitment to executing with focus, operational excellence, and discipline position us to deliver differentiated gamma delta 1 CAR T therapies with the best potential to address medical need for patients." Second Quarter 2025 and Recent Operational Highlights: Autoimmune diseases First SSc patient dosed in ongoing Phase 1 clinical trial in autoimmune diseases. In July 2025, Adicet announced that the first SSc patient was dosed in the second cohort of the Phase 1 clinical trial evaluating ADI-001 in autoimmune disease, in addition to ongoing enrollment in LN and SLE. The Company recently opened enrollment in the Phase 1 trial to include patients with IIM, SPS and AAV. Adicet remains on track to share preliminary clinical data from the Phase 1 trial in the second half of 2025. Solid tumor indications Prioritizing ADI-212 development for prostate cancer. Adicet is advancing ADI-212, an optimized next-generation gene-edited and armored clinical candidate designed to enhance potency in solid tumors and to deliver multiple anti-tumor mechanisms of action to the tumor microenvironment. ADI-212, which targets prostate specific membrane antigen (PSMA), has shown enhanced activity in preclinical studies, suggesting the potential for improved potency and tumor-cell killing capacity compared to previous generation alpha-beta and gamma-delta CAR T programs in oncology. The Company expects to submit a regulatory filing for ADI-212 for the treatment of metastatic castration-resistant prostate cancer (mCRPC) in the first quarter of 2026. Subject to regulatory clearance to proceed with a clinical trial, the Company expects to report initial clinical data from this program in the second half of 2026. Corporate updates Recently announced pipeline prioritization with workforce and cost reduction initiatives. In July 2025, the Company announced a strategic prioritization of its pipeline intended to optimize the development of assets with the greatest potential for clinical and commercial success. In connection with this, the Company has made the decision to discontinue the development of ADI-270 for patients with metastatic/advanced clear renal cell carcinoma (ccRCC) and close enrollment in the ADI-270 Phase 1 clinical trial. Adicet also reduced its workforce by approximately 30% in connection with its strategic pipeline prioritization. The workforce reduction and other expense reductions related to the strategic pipeline prioritization are expected to extend the Company’s cash runway into the fourth quarter of 2026. Financial Results for Second Quarter 2025: Research and Development (R&D) Expenses: R&D expenses were $28.4 million for the three months ended June 30, 2025, compared to $25.9 million during the same period in 2024. The increase in R&D expenses was due to a $1.4 million increase in expenses related to contract development and manufacturing organizations and contracted R&D services, a $1.6 million increase in facility-related expenses, and a $0.2 million increase in lab supplies and materials. This increase was partially offset by a $0.7 million decrease in payroll and personnel expenses primarily related to a decrease in stock-based compensation expense. General and Administrative (G&A) Expenses: G&A expenses were $4.0 million for the three months ended June 30, 2025, compared to $6.9 million during the same period in 2024. The decrease in G&A expenses was due to a $1.8 million decrease in payroll and personnel expenses primarily related to a decrease in stock-based compensation expense and a $1.1 million decrease in facility-related expenses. Net Loss: Net loss for the three months ended June 30, 2025 was $31.2 million, or a net loss of $0.34 per basic and diluted share, including non-cash stock-based compensation expense of $2.9 million, as compared to a net loss of $29.9 million, or a net loss of $0.33 per basic and diluted share, including non-cash stock-based compensation expense of $6.0 million during the same period in 2024. Cash Position: Cash, cash equivalents and short-term investments were $125.0 million as of June 30, 2025, compared to $176.3 million as of December 31, 2024. The Company expects that current cash, cash equivalents and short-term investments as of June 30, 2025, will be sufficient to fund its operating expenses into the fourth quarter of 2026.

ROCKVILLE, Md., Aug. 06, 2025 (GLOBE NEWSWIRE) -- MaxCyte, Inc., (NASDAQ: MXCT), a leading, cell-engineering focused company providing enabling platform technologies to advance the discovery, development and commercialization of next-generation cell therapeutics, today announced its second quarter ended June 30, 2025 financial results and updated its 2025 guidance. Second Quarter and Recent Highlights Core business revenue of $8.2 million in the second quarter of 2025, an increase of 8% over the second quarter of 2024. Strategic Platform License SPL Program-related revenue was $0.3 million for the second quarter of 2025, compared to $2.9 million in the second quarter of 2024, reflecting the timing variability of SPL Program-related revenue milestones and royalties. Total revenue of $8.5 million in the second quarter of 2025, a decrease of 18% over the second quarter of 2024. MaxCyte added two new SPL clients, Adicet Bio and Anocca AB, in July. Including TG Therapeutics signed in the first quarter, the total number of SPLs agreements stands at 31. Total cash, cash equivalents and investments were $165.2 million as of June 30, 2025. The decrease in cash, cash equivalents and investments since the beginning of the year includes approximately $7.0 million of purchase, transaction, and one-time costs to acquire SeQure Dx. “Despite solid growth in the first half of 2025, the operating environment has evolved since the beginning of the year, impacting our expectations for the second half of 2025. We are lowering our 2025 guidance to account for customer inventory management, as well as some reprioritization and consolidation of customer pipelines. While disappointed with the short-term headwinds, we continue to remain focused on executing in this environment, supporting customers with excellent technology and service,” said Maher Masoud, President and CEO of MaxCyte. “Our pipeline of potential SPLs remains strong, demonstrated by the two new SPLs that we recently announced, Adicet Bio and Anocca AB, bringing our total number of SPL agreements to 31. We continue to be confident about the opportunity in the cell and gene therapy industry and our position in it, remaining committed to spending prudently, and investing in product enhancements and SeQure Dx. We are confident that with improving operational efficiencies, multiple product offerings, and maturing clinical programs of our customers, we will achieve profitability with our existing capital.” The following tables provide details regarding the sources of the Company’s revenue for the periods presented. In addition to revenue, management regularly reviews key business metrics to evaluate our business, measure performance, identify trends affecting our business, formulate financial projections and make strategic decisions. As of the dates presented, these key metrics were as follows: Second Quarter 2025 Financial Results Total revenue for the second quarter of 2025 was $8.5 million, compared to $10.4 million in the second quarter of 2024, representing a decrease of 18%. Core business revenue (sales of instruments, PAs and consumables, assay services, and licenses to customers, excluding SPL Program-related revenue) for the second quarter of 2025 was $8.2 million, compared to $7.6 million in the second quarter of 2024, representing an increase of 8%. SPL Program-related revenue was $0.3 million in the second quarter of 2025, as compared to $2.9 million in the second quarter of 2024. Gross profit for the second quarter of 2025 was $7.0 million (82% gross margin), compared to $8.9 million (86% gross margin) in the second quarter of 2024. Non-GAAP adjusted gross margin was 83% excluding SPL Program-related revenue and reserves for excess and obsolete inventory, compared to non-GAAP adjusted gross margin of 82% in the second quarter of 2024. Operating expenses for the second quarter of 2025 were $21.2 million, compared to operating expenses of $20.9 million in the second quarter of 2024. Second quarter 2025 net loss was $12.4 million compared to net loss of $9.4 million for the same period in 2024. EBITDA, a non-GAAP measure, was a loss of $13.1 million for the second quarter of 2025, compared to a loss of $10.9 million for the second quarter of 2024; stock-based compensation expense was $3.5 million in the second quarter of 2025 compared to $3.6 million in the second quarter of 2024. 2025 Guidance MaxCyte updates 2025 revenue guidance for core business revenue and SPL Program-related revenue: Core revenue is expected to be flat to a 10% decline compared to 2024, inclusive of revenue from SeQure Dx. SPL Program-related revenue is expected to be approximately $5 million for the year. SPL-program related revenue guidance includes both expected revenue from pre-commercial milestone payments and commercial royalties/sales-based payments. MaxCyte now expects to end 2025 with at least $155 million in total cash, cash equivalents and investments.

Non-GAAP Financial Measures This press release contains EBITDA, which is a non-GAAP measure defined as earnings before interest income and expense, taxes, depreciation and amortization. MaxCyte believes that EBITDA provides useful information to management and investors relating to its results of operations. The company’s management uses this non-GAAP measure to compare the company’s performance to that of prior periods for trend analyses, and for budgeting and planning purposes. The company believes that the use of EBITDA provides an additional tool for investors to use in evaluating ongoing operating results and trends and in comparing the company’s financial measures with other companies, many of which present similar non-GAAP financial measures to investors, and that it allows for greater transparency with respect to key metrics used by management in its financial and operational decision-making. This press release also contains Non-GAAP Gross Margin, which we define as Gross Margin when excluding SPL program related revenue and reserves for excess and obsolete inventory. The Company believes that the use of Non-GAAP Gross Margin provides an additional tool to investors because it provides consistency and comparability with past financial performance, as Non-GAAP Gross Margin excludes non-core revenues and inventory reserves, which can vary significantly between periods and thus affect comparability. Management does not consider these Non-GAAP financial measures in isolation or as an alternative to financial measures determined in accordance with GAAP. The principal limitation of these Non-GAAP financial measures is that they exclude significant revenues and expenses that are required by GAAP to be recorded in the Company’s financial statements. In order to compensate for these limitations, management presents these Non-GAAP financial measures along with GAAP results. Non-GAAP measures should be considered in addition to results prepared in accordance with GAAP, but should not be considered a substitute for, or superior to, GAAP results. Reconciliation tables of net loss, the most comparable GAAP financial measure, to EBITDA, and Gross Margin, the most comparable GAAP financial measure, to Non-GAAP Gross Margin, are included at the end of this release. MaxCyte urges investors to review the reconciliation and not to rely on any single financial measure to evaluate the company’s business Forward-Looking Statements This press release contains "forward-looking statements" within the meaning of the "safe harbor" provisions of the Private Securities Litigation Reform Act of 1995.

Two programs with clinical data readouts in 2H/2025 Phase 1 clinical trial of ADI-001 in autoimmune diseases ongoing with preliminary clinical data expected in 2H/2025; Trial now open for enrollment to patients with lupus nephritis (LN) and systemic lupus erythematosus (SLE) Preliminary data for ongoing ADI-270 Phase 1 clinical trial in patients with metastatic/advanced clear cell renal cell carcinoma (ccRCC) expected in 2H/2025 REDWOOD CITY, Calif. & BOSTON, May 06, 2025--(BUSINESS WIRE)--Adicet Bio, Inc. (Nasdaq: ACET), a clinical stage biotechnology company discovering and developing allogeneic gamma delta T cell therapies for autoimmune diseases and cancer, today reported financial results and operational highlights for the first quarter ended March 31, 2025. "We are approaching an exciting inflection point for our pipeline, with significant data milestones on the horizon," said Chen Schor, President and Chief Executive Officer of Adicet Bio. "In the second half of 2025, we expect to report preliminary Phase 1 data from our two lead programs - ADI-001 in autoimmune diseases and ADI-270 in ccRCC, with more than 6 patients with at least 3-month follow up in both programs. As we progress toward these readouts, we also look to harness the full potential of our allogeneic gamma delta 1 CAR T cell therapy platform, which we believe has key advantages over other cell types. We have identified two promising highly differentiated programs, one targeting PSMA and one follow-on program targeting autoimmune diseases with potential to become best-in-class therapies for patients fighting autoimmune diseases and cancer." First Quarter 2025 and Recent Operational Highlights: Autoimmune diseases Enrollment open for LN and SLE patients in Phase 1 clinical trial of ADI-001 in autoimmune diseases. In April 2025, Adicet expanded enrollment in its Phase 1 trial to include patients with SLE, in addition to ongoing enrollment in LN. The Company expects to initiate enrollment for patients with systemic sclerosis (SSc), idiopathic inflammatory myopathy (IIM), stiff person syndrome (SPS) and anti-neutrophil cytoplasmic autoantibody associated vasculitis (AAV) in the Phase 1 trial in 3Q/2025. Preliminary clinical data from the trial is expected in 2H/2025, subject to study site initiation and patient enrollment. ADI-001 granted two new Fast Track Designations. In February 2025, the Food and Drug Administration (FDA) granted Fast Track Designation to ADI-001 for the treatment of refractory SLE with extrarenal involvement and for SSc. Hematologic malignancies and solid tumor indications Patient enrollment ongoing in Phase 1 trial of ADI-270 in metastatic/advanced ccRCC.
