Revlimid fades, semaglutide must prove itself

01 Running thesis

A bridge after Revlimid

Dr. Reddy's is in a hard handoff. Generic Revlimid, also called lenalidomide, was a major profit source, but its January 2026 patent cliff is now active. North America is already feeling that pressure.

The bull case is that management has real tools to cross the gap. The NRT consumer health deal has lifted Europe, semaglutide is approved in Canada and India for type 2 diabetes, and the Abatacept IV biosimilar filing was accepted by the FDA. Those are not small milestones.

The bear case is that each bridge piece still has to earn its keep. Generic GLP-1 drugs such as semaglutide can get crowded fast, and management itself framed a likely floor near $25 to $30 in some markets. Biosimilars can be large, but past CRLs for rituximab and partner Alvotech's denosumab show that approval is not automatic.

Finn's view is mixed but not negative. The stock has a decent valuation setup and sound balance sheet, while performance and sentiment are held back by the Revlimid drop, quality watch items, and launch risk.

May 2026Q4 confirmed that semaglutide is approved in Canada and India, and that Abatacept IV was accepted by the FDA for review. The thesis improves on execution, but stays balanced because Revlimid pressure and semaglutide pricing risk are now live.
Jan 2026Dr. Reddy's completed the Abatacept IV BLA filing in December 2025, as planned. That reduced a key timeline risk, even as the Revlimid cliff began to hit North America.
Oct 2025Q2 showed Europe growing fast from the NRT deal while North America kept sliding on Revlimid. Management also added a U.S. CMO for Abatacept, which helps reduce launch and tariff risk.
Jul 2025Q1 showed clear Revlimid price erosion in North America and a Form 483 with 7 observations at Srikakulam FTO 11. Europe growth helped, but the risk mix worsened.
May 2025The starting thesis centered on whether Dr. Reddy's could bridge the January 2026 Revlimid cliff. Management pointed to consumer health, semaglutide, Abatacept, and biosimilars as the main bridge pieces.
02 Business model

Generics cash, harder launches

Dr. Reddy's makes money by selling generic medicines around the world. It also sells active pharmaceutical ingredients, the chemical building blocks inside drugs, and does some CDMO work, which means manufacturing or development work for other drug companies.

The old model leaned on broad generic scale, especially in North America. The newer model aims for higher-value areas: consumer health through nicotine replacement therapy, complex generics like semaglutide, innovative products in India and emerging markets, and biosimilars.

Management wants double-digit sales growth and about 25% EBITDA margin over time. FY2026 adjusted EBITDA margin was 24.7%, but Q4 was closer to 19.5% on adjusted revenue after the Revlimid reset. Management has also pointed to a 500 to 600 basis point discretionary cost lever in SG&A and R&D if margins need defense.

This model breaks if new launches arrive late, price too low, or fail inspection. It also breaks if the base U.S. generic business keeps eroding faster than Europe, India, emerging markets, and PSAI can grow.

03 Product portfolio

What fills the medicine cabinet

Cash cow

Global generics

This is the core business: copies of branded drugs sold after patent protection fades. North America remains important, but it is under pressure from Revlimid erosion and normal generic price cuts.

Cash cow

Lenalidomide, generic Revlimid

Lenalidomide has been a major contributor, but the patent cliff is now active. Q4 FY2026 included a shelf-stock adjustment tied to this product, which makes the drop very visible.

Growth engine

Nicotine replacement therapy consumer health

The acquired NRT business gives Dr. Reddy's a consumer health leg in Europe. Management said integration is largely complete and expects the business to grow above its original mid-single-digit view.

Growth engine

Semaglutide

This is the key complex generic launch. It is approved in Canada and India for type 2 diabetes, and management is targeting calendar 2026 launches across approved markets, with pricing risk still central.

Option

Abatacept biosimilar

The IV version was filed in December 2025 and accepted by the FDA in February 2026. Management points to a likely early calendar 2027 launch if approval and inspections go well.

Option

Other biosimilars and partnerships

The company has partnered assets such as denosumab and a collaboration with Alvotech for pembrolizumab. These can be large, but CRLs and deficiency letters show that the path is uneven.

Steady

India brands and in-licensed products

India is growing double digits, helped by launches, price increases, volume, and selected brand deals. The business also includes in-licensed vaccines and innovative products.

04 Business segments

Where sales come from

North America Generics37%declining
Emerging Markets20%growing fast
India18%growing fast
Europe15%growing fast
PSAI and other10%declining

The mix uses FY2026 revenue disclosed on the May 12, 2026 earnings call, converted with management's stated INR 93.83 convenience rate where needed. North America is the largest bucket, but it is also the one most exposed to Revlimid.

05 Risk factors

What can still break

Revlimid cliff cuts deeper

High impact · High odds

The January 2026 Revlimid cliff is no longer a future worry. North America revenue fell because of lenalidomide, and Q4 included a shelf-stock adjustment tied to the product. If the base U.S. business does not grow fast enough, margin pressure can linger.

We watchNorth America revenue excluding lenalidomide and any new shelf-stock adjustments.

Semaglutide price war

High impact · Medium odds

Semaglutide approval in Canada and India lowers approval risk, but the real test is market formation. Management expects Canada to be competitive and framed some prices around $25 to $30, with higher prices in some markets. More entrants or an authorized generic from Novo could push realized prices below plan.

We watchCanada list price, public reimbursement price, entrant count, and management's unit guidance for calendar 2026.

India semaglutide IP loss

Medium impact · Medium odds

Dr. Reddy's launched semaglutide in India, but the company has also been challenging patents in the Delhi High Court. A bad ruling could limit sales or change launch economics. That would matter because India is one of the approved early markets.

We watchDelhi High Court rulings or settlement terms related to semaglutide patents.

Biosimilar approval delays

High impact · Medium odds

Biosimilars are a big part of the post-Revlimid plan, especially Abatacept. The IV BLA is accepted for review, but inspections and final FDA decisions still matter. CRLs for rituximab and partner Alvotech's denosumab show that setbacks are possible.

We watchFDA inspection outcome for Bachupally, Abatacept IV decision timing, and denosumab deficiency resolution.

Quality and tariff pressure

Medium impact · Medium odds

Recent FDA inspections produced Form 483 observations, though Srikakulam FTO 11 received VAI classification. Potential U.S. generic or API tariffs could also hurt supply chains and margins. A U.S. CMO for Abatacept helps, but it does not remove the whole risk.

We watchNew FDA 483s, warning letters, import alerts, and any U.S. tariff policy covering generics or APIs.
06 Quick answers

In one breath

What does Dr. Reddy's Laboratories do?

Dr. Reddy's sells generic medicines, active pharmaceutical ingredients, consumer health products, and biosimilars. Its main markets include North America, Europe, India, and emerging markets.

Why does Revlimid matter so much for RDY?

Revlimid is the branded drug name for lenalidomide, and Dr. Reddy's generic version was a major contributor. The patent cliff began in January 2026, so more competition and lower prices are now pressuring North America sales.

Is semaglutide already approved for Dr. Reddy's?

Yes, the injectable semaglutide product for type 2 diabetes is approved in Canada and India. The next question is not only approval, but how many pens sell and at what price as more competitors enter.

What is the next big catalyst for RDY?

Semaglutide launches across Canada and other approved markets are the near-term focus in calendar 2026. Abatacept IV has an FDA review underway, with management pointing to a likely early calendar 2027 launch if approval is received.
