CAMBRIDGE, Mass., October 27, 2026 – Wave Life Sciences, Inc. (Nasdaq: WVE), a clinical-stage biotechnology company focused on unlocking the broad potential of RNA medicines to transform human health, today announced financial results for the third quarter ended September 30, 2026, and provided a business update.

“We continue to make notable progress advancing our lead clinical programs. Following positive FDA feedback, planning is underway for our potentially registrational trial of WVE-006 for AATD, which we believe offers an efficient path to potential full and accelerated approval, without the need for a separate confirmatory trial. Our growing body of clinical data support WVE-006’s potential to offer a new standard of care for individuals living with AATD,” said Paul Bolno, MD, MBA, President and Chief Executive Officer at Wave Life Sciences. “We also continue to make notable progress advancing WVE-007 across treatment settings. Dosing is ongoing in our Phase 2a INLIGHT ™ trial evaluating WVE-007 as a monotherapy. As expected, we are pleased to report that to date baseline levels of adiposity in the Phase 2a portion of INLIGHT are substantially higher than in the Phase 1 portion and in line with Phase 2 and 3 obesity trials. We believe this portion of the trial is well suited to demonstrate WVE-007’s potential to deliver meaningful improvements in body composition and healthy weight loss. Our combination trial of WVE-007 with weekly tirzepatide is underway, where we believe WVE-007 can demonstrate enhanced fat loss and cardiometabolic benefit, without additional muscle loss. We also remain on track to initiate a post-incretin maintenance trial of WVE-007 in the fourth quarter that has the potential to unlock an entirely new frontier in obesity by enabling patients an off-ramp for their incretin therapy.”

Dr. Bolno added, “Importantly, our PRISM platform and chemistry continue to demonstrate unique value both within our own pipeline and beyond. The advancement of a development candidate by GSK reflects the recognition of Wave’s differentiated technology, including our best-in-class siRNA with SpiNA design, with three additional collaboration programs still advancing. The appointment of Monika Vnuk, with her breadth of experience, in our newly-created role of Chief Business Officer, is meant to capitalize on and expand the potential of our platform

and support the next phase of Wave’s growth. We look forward to sharing new data supporting our platform and capabilities at our upcoming Research Day next week, where we will be joined by a leading hepatologist who will discuss PNPLA3 I148M liver disease and opportunity for an RNA editing approach.”

Recent Business Highlights and Expected Milestones

Obesity

•

WVE-007 is an investigational GalNAc-siRNA (SpiNA) designed to induce fat

loss without muscle loss. With strong evidence from human genetics, silencing INHBE mRNA is a promising therapeutic strategy to treat obesity, distinct from incretin-based approaches. Wave plans to evaluate WVE-007 across three treatment settings: as a monotherapy, in combination with incretins, and as a post-incretin maintenance therapy. WVE-007 is currently being evaluated in the ongoing placebo-controlled INLIGHT™ clinical program, which includes a monotherapy and combination portion.

•

Monotherapy: Dosing is underway in the Phase 2a portion of the INLIGHT trial of WVE-007 in individuals with higher BMI (35-50 kg/m2), with and without type 2 diabetes. This portion of the INLIGHT trial is evaluating participants with greater adiposity and is enrolling participants across the U.S. and Europe. The trial includes multiple assessments over a 12-month period, including body weight, waist circumference, body composition (MRI and DEXA), liver fat (MRI-PDFF), HbA1c, and lipid levels

CAMBRIDGE, Mass., April 28, 2026 – Wave Life Sciences Ltd. (Nasdaq: WVE), a clinical-stage biotechnology company focused on unlocking the broad potential of RNA medicines to transform human health, today announced financial results for the first quarter ended March 31, 2026, and provided a business update.

“We’re accelerating WVE-007 to the next stages of development following the improvements in body composition already observed in the Phase 1 portion of our INLIGHT trial, including profound reductions in harmful visceral fat, along with favorable safety and potential for once to twice yearly dosing,” said Paul Bolno, MD, MBA, President and Chief Executive Officer at Wave Life Sciences. “This quarter, we expect to initiate the Phase 2a portion of INLIGHT in individuals with higher BMI and excess fat. Given WVE-007’s mechanism of targeted lipolysis, we believe this portion of the study can deliver even more pronounced improvements in body composition. Importantly, we’ve designed the Phase 2a study to assess additional biomarkers of cardiometabolic health, which will inform WVE-007’s broad potential across obesity and multiple indications, including MASH, type 2 diabetes, and cardiovascular disease. We also plan to rapidly initiate investigation of WVE-007 in both the combination and maintenance settings soon thereafter.”

Dr. Bolno added, “We continue to make significant progress advancing our RNA editing pipeline led by WVE-006 for AATD. Clinical data from our ongoing RestorAATion-2 trial of WVE-006 has already demonstrated the potential to provide a much-needed new therapeutic option. By correcting the root cause of disease, WVE-006 restores dynamic AAT production to address lung manifestations and lowers harmful Z-AAT to address liver manifestations of the disease, with a therapy that is well-tolerated, non-permanent, and highly specific. WVE-006 also avoids delivery with LNPs and collateral bystander edits and indels associated with DNA base editing. In May, we expect

to highlight data from our RestorAATion-2 trial, including results from our less frequent, 400 mg monthly dose and 600 mg single dose cohorts. We remain on track to receive regulatory feedback on a potential accelerated approval pathway for WVE-006 mid-year. Building on our clinical success in RNAi and RNA editing, we are advancing WVE-008, as well as a pipeline of additional hepatic and extra-hepatic siRNAs and AIMers.”

Phase 1 INLIGHT: In March 2026, Wave announced interim results from the ongoing Phase 1, single-ascending dose portion of its INLIGHT trial in healthy individuals with overweight or obesity (average BMI of ~32 kg/m2, a population with less fat and lower BMI than those in Phase 2 and Phase 3 obesity studies), which showed further improvements in body composition at six months following a single dose of WVE-007. WVE-007 continued to be generally safe and well tolerated. At six-month follow-up, a single 240 mg dose of WVE-007 demonstrated continued total body fat reduction (-5.3%) with muscle preservation (+2.4%), as well as clinically meaningful reductions in visceral fat (-14.3%; p<0.05) and waist circumference (-3.3%) – exceeding the 5–10% visceral fat reductions that support robust correlations to clinical outcomes (lower risk of MASH, T2D, and CVD)1. Preservation of muscle is a key differentiator from incretin treatments and is linked to health benefits including higher basal metabolic rate, improved insulin sensitivity, and prevention of weight regain. Activin E reductions were robust and
