AstraZeneca Stock Declines 6% in 3 Months: Time to Buy the Dip?

By Kinjel Shah | May 21, 2025, 9:05 AM

AstraZeneca AZN stock has declined 6.4% in the past three months.

Although AstraZeneca faces its share of challenges, a significant portion of this price decline is attributed to broader market uncertainties and a volatile macroeconomic environment.

The sky-high tariffs imposed by the United States and retaliatory tariffs by China and some other countries hurt global stock markets. Though the massive tariffs imposed by the United States and China are now on a pause, it is only a temporary suspension, and no one knows what will happen after the 90-day tariff suspension ends. The uncertainty around tariffs and trade production measures remains, slowing down economic growth.

Although pharmaceuticals have been exempted from tariffs in the first round, they could be Trump’s target in the next round, considering the President’s goal to shift pharmaceutical production back to the United States, primarily from European and Asian countries. 

Trump and the Republican government also continue to stress on the control of drug prices with the latest attempt being his “most favored nations’ policy.”

Let’s understand AZN’s strengths and weaknesses to better analyze how to play the stock in an uncertain macro environment.

AZN’s Strong Portfolio of Blockbuster Drugs

AstraZeneca boasts a diversified geographical footprint as well as a product portfolio with several blockbuster medicines. AstraZeneca now has 16 blockbuster medicines in its portfolio with sales exceeding $1 billion, including Tagrisso, Fasenra, Farxiga, Imfinzi, Lynparza (partnered with Merck [MRK]), Calquence and Ultomiris. These drugs are driving the company’s top line, backed by increasing demand trends. The company is confident that the growth will continue in 2025. Almost every new product it has launched in recent years has done well.

Newer drugs like Wainua, Airsupra, Saphnelo, Datroway (partnered with Daiichi Sankyo) and Truqap are also expected to continue to contribute to top-line growth in 2025.

AZN Enjoys Strong Position in the Oncology Space

Oncology is AstraZeneca’s biggest segment. The company is working on strengthening its oncology product portfolio through label expansions of existing products and progressing oncology pipeline candidates. Oncology sales (comprising around 41% of AstraZeneca‘s total revenues) rose 13% in the first quarter of 2025, generating $5.6 billion in sales. The strong oncology performance is being driven by medicines such as Tagrisso, Merck-partnered Lynparza, Imfinzi, Calquence and Daiichi Sankyo-partnered Enhertu.

A key new cancer drug approval was that of Truqap for HR-positive, HER2-negative (HR+ HER2-) breast cancer. The drug has seen a robust launch, recording sales of $430 million in 2024 and $132 million in the first quarter of 2025. In January this year, AstraZeneca and partner Daiichi’s drug, Datroway, was approved by the FDA for HR+ HER2- breast cancer, while a regulatory application is under review for EGFR-mutated non-small cell lung cancer (NSCLC). Datroway witnessed encouraging early launch signals in the United States.

AstraZeneca expects continued growth of its oncology medicines in 2025, particularly Tagrisso, Enhertu and Imfinzi, despite the incremental impact of the Part D redesign.

Several Headwinds to Hurt AZN’s Top Line in 2025

The impact of Part D redesign hurt sales of AZN’s older drugs, Tagrisso, Lynparza and Ultomiris, as well as newer drugs, Truqap and Wainua, in the United States in the first quarter of 2025, with the trend expected to continue through the rest of the year.

AstraZeneca expects Farxiga and Lynparza to be included in the volume-based procurement plans in China in mid-2025, which can hurt sales of these drugs in the country.

Pricing and competitive pressure in Europe and generic competition in some emerging markets are expected to hurt sales of some drugs. Brilinta generics are expected to be launched in the United States in 2025. This will hurt sales of the drug. Biosimilar versions of Soliris were launched in the United States in March 2025, which, along with successful conversion to Ultomiris, biosimilar pressure in Europe and unfavorable order timing in certain tender markets, is expected to lead to a continuous decline in sales of Soliris.

AstraZeneca is facing ongoing investigations at its China subsidiary. The Chinese authorities are investigating some current and former AstraZeneca employees at its China subsidiary for medical insurance fraud, illegal drug importation and personal information breaches.

Consider Buying AZN Stock

Despite the potential impact from Part D redesign, AstraZeneca expects total revenues to grow by a high single-digit percentage at CER in 2025. Growth momentum in Oncology and CVRM(cardiovascular, renal and metabolism) segments is expected to continue in 2025. However, in Rare Disease, though AstraZeneca expects growth in 2025, it will be at a slower pace than in 2024.

Regarding the potential impact of tariffs, AstraZeneca had a positive tone on the first-quarter conference call. The company said it has limited commercialized finished medicines imported to the United States from China, which lowers its exposure to potential China tariffs on pharmaceuticals. It also has a substantial and growing manufacturing footprint in the United States, and the majority of its medicines sold in the United States are manufactured domestically.

It does import some medicines from Europe but believes that if tariffs on pharmaceutical imports from Europe are implemented in a similar range as other industries, it will be manageable and allow the company to remain within its guidance range for EPS. In 2025, AstraZeneca expects core EPS to increase by a low double-digit percentage.

Backed by its new products and pipeline drugs, AstraZeneca believes it can post industry-leading top-line growth in the 2025-2030 period. AstraZeneca expects to generate$80 billion in total revenues by 2030, a significant increase from the $54 billion it generated in 2024. By the said time frame, AstraZeneca plans to launch 20 new medicines, with nine new medicines already launched/approved. It believes that many of these new medicines will have the potential to generate more than $5 billion in peak-year revenues.

The company is also on track to achieve a mid-30s percentage core operating margin by 2026

Considering AZN’s growth prospects, investors may take advantage of the recent dip and consider buying this Zacks Rank #2 (Buy) stock, more so as it is trading below its five-year mean. Consistently rising estimates also indicate analysts’ optimistic outlook for growth. You can see the complete list of today’s Zacks #1 Rank (Strong Buy) stocks here.
