&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *DECLARATION trial Independent Data Monitoring Committee (IDMC) ad hoc review of unblinded VYD2311 safety data resulted in IDMC recommendation for reduction of post-dose monitoring time from two hours to thirty minutes* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Operating expense increase quarter-over-quarter primarily attributable to DECLARATION pivotal program costs for VYD2311 for which top-line data is anticipated in Q3 2026* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Strong balance sheet with Q1 2026 ending cash and cash equivalents of $184.2 million; additional ~$20 million in gross proceeds from usage of at-the-market (ATM) offering facility in April 2026* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *Invivyd to host conference call today at 8:30AM ET* 

NEW HAVEN, Conn., May 14, 2026 (GLOBE NEWSWIRE) — Invivyd, Inc. (Nasdaq: IVVD) today announced financial results for the first quarter ended March 31, 2026, and recent business highlights.

"Invivyd is moving forward as fast as possible to bring Americans a solution to the major current problem in infectious disease prevention," said Marc Elia, Chairman of the Board of Invivyd. "Our VYD2311 REVOLUTION clinical program is proceeding on track, with the LIBERTY head-to-head safety and combination study of VYD2311 versus mRNA COVID vaccine planned to begin shortly. Related, we were pleased to recently publish a <u>preprint</u> focused on the side effect profile of a past Invivyd low-dose monoclonal antibody for COVID-19 prevention versus COVID vaccines that builds on <u>recently presented randomized data</u> demonstrating high degrees of systemic side effects following COVID vaccination, in strong contrast to our investigational COVID-19 monoclonal antibody approach. Further, and as we expected, we have confirmed in vitro neutralization activity of Omicron BA.3.2.2 variant virus with our antibodies. <u>As a variant that appears to escape vaccine-induced neutralization</u>, we note once again that our monoclonal antibodies have the potential to allow America to break the unsatisfactory annual cycle of trying to play catch-up with poorly tolerated, variant-specific vaccine boosts. Millions of vulnerable Americans deserve a better way to stay well, and we are working hard to bring a new option forward."

"PEMGARDA revenue continues to grow even as vaccine uptake appears to wane, and we are managing expenses diligently outside of our non-recurring pivotal clinical trial expenditures," commented Bill Duke, Chief Financial Officer of Invivyd. "We look forward to continued commercial execution, as well as managing our overall expenses responsibly as we anticipate the end of major clinical spending on VYD2311 later this summer. Meanwhile, we are pleased with our continued balance sheet strength and are well into launch planning for VYD2311."

------

**Recent Business Highlights** 

• **Clinical & Regulatory Developments** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Invivyd reports positive, continued, *in vitro* neutralization data for PEMGARDA<sup>®</sup> (pemivibart) and for VYD2311, the company's vaccine alternative monoclonal antibody candidate for the prevention of COVID-19, against SARS-CoV-2 variant BA.3.2.2 ("Cicada").

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Invivyd announces that the Independent Data Monitoring Committee (IDMC), responsible for monitoring the safety in
the DECLARATION trial, recently completed an ad hoc review of unblinded safety data for VYD2311 in the DECLARATION trial that resulted in the IDMC recommendation for reduction of post-dose monitoring time from two hours to 30 minutes.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In April 2026, Invivyd announced that the IDMC completed its prespecified review of unblinded safety data at an
early timepoint, as defined in the protocol, for VYD2311 in the DECLARATION trial and returned the following recommendations:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Pregnant and breastfeeding women are now eligible to participate in the study and may enroll.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Women of childbearing age are no longer required to use contraception.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Further pre-existing protocol-specified safety visits and evaluations at
Day 8, Day 38, and Day 68 are no longer required.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• During March and April 2026, Invivyd provided updates on its REVOLUTION program, which is Invivyd's
development program for VYD2311 that is designed to elaborate the profile of monoclonal antibody-mediated prophylaxis from COVID-19 and the potential medical benefits to vulnerable Americans:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *DECLARATION:* Following trial initiation in late 2025, the DECLARATION pivotal clinical trial recruitment
progressed rapidly with full initial enrollment achieved in March 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In April 2026, Invivyd announced that confirmed, pooled, blinded COVID-19 events in the ongoing DECLARATION clinical trial accumulated to date (~ 50% of study progress) could already provide sufficient statistical power to support the high end of anticipated VYD2311 efficacy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Invivyd conducted a pre-specified blinded sample size re-estimation analysis when 1,500 of 1,818 enrolled patients reached Day 45 of 90 total days (April 6th), designed to add robustness given future event rate variability; upsizing was triggered and increases
confidence in overall study statistical power.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• DECLARATION upsizing provides ~500 additional subjects and will likely shift study result timing modestly, by
approximately two months, from original "mid-year" guidance to Q3 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *DRUMMER*: Invivyd agreed with the U.S. Food and Drug Administration (FDA) on an initial pediatric study
plan to support Biologics License Application (BLA) filing. The plan includes a single clinical trial ("DRUMMER") which will assess the immunogenicity and safety of VYD2311 in children 0 – 11 years of age, with efficacy
extrapolation from DECLARATION.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• *LIBERTY:* In February 2026, Invivyd announced it received and was aligned with advice from the FDA on the
LIBERTY Phase 3 clinical trial, which will assess the safety and immunologic profile of VYD2311 versus commercially available mRNA COVID vaccines.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The FDA, providing feedback jointly from CDER and CBER, requested specific monitoring of adverse events of
special interest relevant to mRNA COVID vaccines, citing the known risk of myocarditis/pericarditis in the young adult population following mRNA COVID vaccination; no similar requests have been made for other Invivyd clinical trials without an mRNA
COVID vaccine arm.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In January 2026, Invivyd and the SPEAR (Spike Protein Elimination and Recovery) Study Group
announced the plan to initiate a Phase 2 clinical trial evaluating VYD2311 in individuals with Long COVID or COVID vaccine injury. The Phase 2 clinical trial is expected to be initiated mid-2026.

• **Publications & Presentations** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In May 2026, Invivyd published a preprint "Safety first: should the high tolerability of intramuscular
anti-spike COVID-19 monoclonal antibody change our expectations of vaccine safety?" Linked <u>here</u>. The analysis supports the strong early tolerability profile of intramuscular-administered
adintrevimab, a low-dose investigational monoclonal antibody for the prevention of COVID-19 that is the parent antibody to pemivibart and VYD2311.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• A post-hoc evaluation of the EVADE trial , a Phase 2/3 double-blind,
randomized, placebo-controlled study of adintrevimab, assessed the rates of systemic side effects (e.g., headache, chills, fever, fatigue, myalgia, diarrhea, nausea, and vomiting) associated with adintrevimab and observed only 2% of participants in
the adintrevimab group and 1% in the placebo group reported at least one systemic treatment-emergent adverse event within the first seven days post-dose.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Recent data from Sanofi's COMPARE study — a head-to-head Phase 4 study that compared tolerability of Sanofi's NUVAXOVID to Moderna's mNEXSPIKE – observed very high rates of systemic adverse events (Grades 1/2/3)\* within seven
days post-booster vaccine dose (84% and 92% of participants), and meaningful impacts on daily activity.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• To further investigate the risk-benefit of these modalities, the LIBERTY clinical trial will evaluate the
comparative safety, tolerability, and pharmacokinetics of VYD2311 versus mRNA COVID-19 vaccination.

*\*Invivyd's May 11, 2026 press release titled "Invivyd and Collaborators Author New Manuscript Evaluating Early Tolerability of COVID Monoclonal Antibody and Comparing Results to COVID Vaccination" has been updated on its website for a scrivener's error and now reflects systemic adverse events as Grades 1/2/3.* 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In March 2026, Invivyd announced Chief Scientific Officer, Robert Allen, Ph.D., presented as part of the
"Antibodies for Infectious Disease Workshop" at the World Vaccine Congress Washington.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Dr. Allen's presentation, titled "Developing mAb Therapies that Keep Pace with Rapidly Evolving
Viral Threats," conveyed the ability of monoclonal antibodies to address virus variation.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The key challenges that have impacted broad utilization of monoclonal antibodies to date are scalability, access,
economics, and the ability to address virus variation. Dr. Allen's presentation focused on how to address virus variation. Dr. Allen's slides can be seen <u>here</u>, and describe Invivyd's early discovery pipeline.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The World Vaccine Congress is a series of conferences and exhibitions that have grown over 25 years to become the
largest vaccine meetings of their kind across the globe. The event format allows for whole-sector topics with hundreds of speakers and covers the complete vaccine value chain, enabling thousands of attendees from science, government, and
manufacturers to come together to create ground-breaking progress.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• More information can be found at <u>https://www.terrapinn.com/conference/world-vaccine-congress-washington/index.stm</u> <u> </u> 

• **Pipeline Expansion** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In April 2026, Invivyd announced advancement of a measles monoclonal antibody candidate, VMS063.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• VMS063 is a novel, highly potent, broadly in vitro neutralizing, high resistance barrier, half-life-extended,
potentially first- and best-in-class monoclonal antibody candidate for the treatment and prevention of measles.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Invivyd has begun Investigational New Drug (IND)-enablement and regulatory outreach to support rapid VMS063
development; goal is expedited development with target IND readiness in late 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Invivyd expects to advance VBY329 toward IND readiness in 2H 2026 for development in pediatric RSV prophylaxis, a
blockbuster pharmaceutical market in 2024, expected to grow to $3-$4 billion in annual revenues globally by 2030.

**•** **Corporate Updates** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In April 2026, Marc Elia spoke at the POLITICO Health Care Summit. During the session, Mr. Elia framed the
evolving landscape of viral disease prevention, including the role of monoclonal antibodies in keeping Americans healthy moving forward.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• In April 2026, Invivyd launched "Antibodies for Any Body" in partnership with world ski champion
Lindsey Vonn to inspire actions that support immune health.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• The national education campaign aims to educate Americans about antibodies and their role in immune health.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Campaign centerpiece, <u>AntibodiesforAnyBody.com</u>, offers an interactive immune health
wellness assessment to empower people to better understand the relationship between their daily habits and immune health and wellness.

**•** **First Quarter 2026 Financial Results** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Revenue:** Reported Q1 2026 net product revenue of PEMGARDA of $13.7 million, compared to
$11.3 million in Q1 2025, representing a 22% increase.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Cash Position:** Cash and cash equivalents were $184.2 million as of March 31, 2026. In April
2026, Invivyd raised an additional ~$20 million in gross proceeds from the sale of common stock pursuant to its at-the-market (ATM) offering facility. Cash and cash
equivalents are anticipated to provide runway through DECLARATION pivotal data readout and support potential commercial launch of VYD2311.

------

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Research & Development (R&D) Expenses:** R&D expenses were
$30.7 million for the quarter ended March 31, 2026, compared to $10.6 million for the comparable period in 2025. This increase is primarily attributable to higher contract research costs associated with the DECLARATION clinical trial
for VYD2311.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Selling, General & Administrative (SG&A) Expenses:** SG&A expenses were
$25.1 million for the quarter ended March 31, 2026, compared to $16.8 million for the comparable period in 2025. This increase is primarily attributable to an increase in personnel-related costs and commercial and marketing-related
costs.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• **Net Loss and Net Loss per Share:** Net loss was $41.4 million for the quarter ended March 31,
2026, compared to $16.3 million for the comparable period in 2025. Basic and diluted net loss per share was $0.13 for the quarter ended March 31, 2026, compared to $0.14 for the comparable period in 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Total shares of common stock outstanding as of March 31, 2026 were 282,803,863, excluding pre-funded warrants totaling 27,342,442 which were included in shares outstanding utilized to calculate net loss per share.

**About PEMGARDA** 

PEMGARDA<sup>®</sup> (pemivibart) is a half-life extended investigational monoclonal antibody (mAb). PEMGARDA was engineered from adintrevimab, Invivyd's investigational mAb that has a robust safety data package and provided evidence of clinical efficacy in global Phase 2/3 clinical trials for the prevention and treatment of COVID-19. PEMGARDA has demonstrated in vitro neutralizing activity against major SARS-CoV-2 variants, including JN.1, KP.3.1.1, XEC, LP.8.1 and XFG. PEMGARDA targets the SARS-CoV-2 spike protein receptor binding domain (RBD), thereby inhibiting virus attachment to the human ACE2 receptor on host cells.

PEMGARDA (pemivibart) injection (4500 mg), for intravenous use is an investigational mAb that has not been approved, but has been authorized for emergency use by the U.S. FDA under an EUA for the pre-exposure prophylaxis (prevention) of COVID-19 in adults and adolescents (12 years of age and older weighing at least 40 kg) who have moderate-to-severe immune compromise due to certain medical conditions or receipt of certain immunosuppressive medications or treatments and are unlikely to mount an adequate immune response to COVID-19 vaccination. Recipients should not be currently infected with or have had a known recent exposure to an individual infected with SARS-CoV-2.

PEMGARDA is not authorized for use for the treatment of COVID-19, Long COVID, or COVID-19 Post-Vaccination Syndrome, or for post-exposure prophylaxis of COVID-19. Pre-exposure prophylaxis with PEMGARDA is not a substitute for vaccination in individuals for whom COVID-19 vaccination is recommended. Individuals for whom COVID-19 vaccination is recommended, including individuals with moderate-to-severe immune compromise who may derive benefit from COVID-19 vaccinations, should receive COVID-19 vaccination. In individuals who have recently received a COVID-19 vaccine, PEMGARDA should be administered at least 2 weeks after vaccination.

------

Anaphylaxis has been observed with PEMGARDA and the PEMGARDA Fact Sheet for Healthcare Providers includes a boxed warning for anaphylaxis. The most common adverse reactions included systemic infusion-related reactions and hypersensitivity reactions, local infusion site reactions, and infusion site infiltration or extravasation. For additional information, please see the PEMGARDA full product Fact Sheet for Healthcare Providers, including important safety information and boxed warning.

To support the EUA for PEMGARDA, an immunobridging approach was used to determine if PEMGARDA may be effective for pre-exposure prophylaxis of COVID-19. Immunobridging is based on the serum virus neutralizing titer-efficacy relationships identified with other neutralizing human mAbs against SARS-CoV-2. This includes adintrevimab, the parent mAb of pemivibart, and other mAbs that were previously authorized for EUA. There are limitations of the data supporting the benefits of PEMGARDA. Evidence of clinical efficacy for other neutralizing human mAbs against SARS-CoV-2 was based on different populations and SARS-CoV-2 variants that are no longer circulating. Further, the variability associated with cell-based EC50 value determinations, along with limitations related to pharmacokinetic data and efficacy estimates for the mAbs in prior clinical trials, impact the ability to precisely estimate protective titer ranges. Additionally, certain SARS-CoV-2 viral variants may emerge that have substantially reduced susceptibility to PEMGARDA, and PEMGARDA may not be effective at preventing COVID-19 caused by these SARS-CoV-2 viral variants.

The emergency use of PEMGARDA is only authorized for the duration of the declaration that circumstances exist justifying the authorization of the emergency use of drugs and biological products during the COVID-19 pandemic under Section 564(b)(1) of the Federal Food, Drug, and Cosmetic Act, 21 U.S.C. § 360bbb-3(b)(1), unless the declaration is terminated or authorization revoked sooner. PEMGARDA is authorized for use only when the combined national frequency of variants with substantially reduced susceptibility to PEMGARDA is less than or equal to 90%, based on available information including variant susceptibility to PEMGARDA and national variant frequencies.

**About VYD2311**

VYD2311 is a novel monoclonal antibody (mAb) candidate being developed for COVID-19 to continue to address the urgent need for new prophylactic and therapeutic options. The pharmacokinetic profile and antiviral potency of VYD2311 may offer the ability to deliver clinically meaningful titer levels through more patient-friendly means such as an intramuscular route of administration.

VYD2311 was engineered using Invivyd's proprietary integrated technology platform and is the product of serial molecular evolution designed to generate an antibody optimized for neutralizing contemporary virus lineages. VYD2311 leverages the same antibody backbone as pemivibart, Invivyd's investigational mAb granted emergency use authorization in the U.S. for the pre-exposure prophylaxis (PrEP) of symptomatic COVID-19 in certain immunocompromised patients, and adintrevimab, Invivyd's investigational mAb that has a robust safety data package and demonstrated clinically meaningful results in global Phase 2/3 clinical trials for the prevention and treatment of COVID-19.

------

**About DECLARATION** 

DECLARATION (NCT07298434) is a Phase 3, randomized, triple-blind, placebo-controlled trial to evaluate VYD2311 efficacy and safety in prevention of symptomatic COVID in a broad population of participants including adults and adolescents both with and without risk factors for progression to severe COVID-19, at three months. Participants will receive either a single dose or a monthly dose of VYD2311, each administered via intramuscular (IM) injection, compared to placebo. Total enrollment of the trial is expected to be approximately 2,301 participants.

**About LIBERTY** 

LIBERTY is a Phase 3, randomized, double-blind clinical trial to evaluate the safety, serum virus neutralizing antibody responses, and pharmacokinetics of VYD2311, an mRNA COVID vaccine, and co-administered VYD2311 with an mRNA COVID vaccine. Total enrollment of the trial is expected to be about 210 participants.
