AbbVie Completes Acquisition of Apogee Therapeutics

• Acquisition deepens AbbVie's robust immunology pipeline with diverse assets targeting dermatologic, respiratory and other inflammatory and immunological diseases
• Apogee's lead asset, zumilokibart, is a late-stage, half-life extended monoclonal antibody targeting IL-13, in development for patients with atopic dermatitis
• Apogee's pipeline also includes APG273, a potential best-in-category long-acting combination targeting IL-13 and thymic stromal lymphopoietin (TSLP), in development for asthma
• AbbVie reaffirms previously issued 2026 full-year adjusted diluted EPS guidance range of $13.87 - $14.07; reaffirms previously issued third-quarter adjusted diluted EPS guidance range of $3.84 - $3.88

NORTH CHICAGO, Ill., Sept. 3, 2026 /PRNewswire/ -- AbbVie (NYSE: ABBV) today announced that it has completed its acquisition of Apogee Therapeutics, Inc. (NASDAQ: APGE). With completion of the acquisition, Apogee is now part of AbbVie. Under the terms of the agreement, Apogee shareholders received $135.11 per share in cash, for a total equity value of approximately $10.9 billion.

"The completion of the Apogee acquisition is an important step in further strengthening AbbVie's leadership in immunology and advancing our long-term growth strategy," said Robert A. Michael, chairman and chief executive officer, AbbVie. "By combining Apogee's innovative science with AbbVie's proven development, regulatory and commercial capabilities, we aim to accelerate these programs and bring promising new treatment options to patients living with serious inflammatory and immunological diseases. We are excited to welcome the talented Apogee team to AbbVie and build on their important work."

Apogee's pipeline includes novel antibodies targeting multiple validated inflammatory pathways in large immunology and inflammation markets, including atopic dermatitis (AD), asthma, and chronic obstructive pulmonary disease (COPD).

Zumilokibart targets IL-13, a critical cytokine in type 2 inflammation, and a central driver of inflammatory diseases like AD and asthma. Specifically in AD, a majority of patients do not achieve simultaneous itch and skin improvement which represents an opportunity for the development of novel treatments that not only provide better skin clearance and itch resolution but also improve convenience with less frequent dosing. In its Phase 2 clinical trial, zumilokibart attained clinically significant results, with approximately two-thirds of patients on treatment achieving significant skin clearance at 16 weeks, along with notable improvements in itch reduction and overall disease control. These findings support its potential best-in-category profile, including strong efficacy and convenient dosing, in patients with AD. Longer-term data from the same trial also support maintenance regimens of either quarterly or twice a year dosing. The safety profile of zumilokibart is favorable and consistent with other medicines in its class, and the molecule has the potential to be evaluated in several additional inflammatory indications.

Beyond zumilokibart, Apogee has built a broader pipeline of novel antibodies targeting multiple validated inflammatory pathways. APG273 combines zumilokibart with APG333, an antibody that blocks thymic stromal lymphopoietin (TSLP), a signaling protein that acts as an early trigger of inflammation in the lungs. Phase 1 data showed that APG333 has a long half-life and was able to suppress relevant type 2 inflammatory markers for up to six months after dosing. The Phase 1 data with APG333 and positive interim results from a Phase 1b study of zumilokibart in asthma, support the potential of the APG273 combination with quarterly or twice-yearly injections in asthma.

Financial Terms
AbbVie has acquired all outstanding Apogee common stock for $135.11 per share in cash, for a total equity value of approximately $10.9 billion. Apogee's common stock ceased trading on the NASDAQ stock exchange prior to market open on Sept. 3, 2026. AbbVie expects its acquisition of Apogee to negatively impact adjusted diluted earnings per share (EPS) by $0.14 in 2026 (partial year) and approximately $0.46 in 2027, with accretion beginning in 2032.

Full-year 2026 Outlook
AbbVie is reaffirming its previously issued 2026 full-year adjusted diluted EPS guidance range of $13.87 - $14.07. This guidance includes a $0.14 per share dilutive impact related to the completed Apogee acquisition. AbbVie's 2026 adjusted diluted EPS guidance includes an unfavorable impact of $0.58 per share related to acquired IPR&D and milestones expense incurred year-to-date through the second quarter. The company's 2026 adjusted diluted EPS guidance excludes any impact from acquired IPR&D and milestones that may be incurred beyond the second quarter of 2026, as both cannot be reliably forecasted.

AbbVie is reaffirming its previously issued 2026 third-quarter adjusted diluted EPS guidance range of $3.84 - $3.88. AbbVie's 2026 third-quarter adjusted diluted EPS guidance excludes any impact from acquired IPR&D and milestones that may be incurred in the quarter, as both cannot be reliably forecasted.
