Six Russian drones struck the Sumy pharmaceutical plant of Kusum Healthcare in Ukraine, severely damaging the facility, and the company says it could stay shut for one to two years. Kusum Group co-founder Sanjeev Gupta told the Times of India that one engineer was killed and other employees were injured, while workers elsewhere in the facility were evacuated. The Kusum Sumy plant drone strike is reported to have taken place on Sunday, 4 October 2026.
Key Takeaways
- Six drones hit the Kusum Healthcare plant in Sumy, Ukraine, according to co-founder Sanjeev Gupta, who called it “a targeted attack”.
- One engineer was killed and other employees were injured, per the company account. Workers in other parts of the facility were evacuated.
- The company expects the plant to be out of operation for one to two years. This is a company estimate, not an independent assessment.
- Reported losses differ: at least Rs 400 crore (about $48 million) in some accounts and more than $50 million in others.
- The company has said it intends to continue operating in Ukraine. We found no Indian government statement on this strike at the time of writing.
What Happened at the Sumy Plant?
Gupta said six drones hit the factory and that, in his words, “it is a targeted attack” and “not by chance”. He also noted that pharmaceutical and food facilities had been attacked repeatedly over the previous month, as reported. Workers in areas of the facility that were not struck were evacuated. The number of injured has not been given, and some reports say the count may rise.
Descriptions of the damage vary. Reports say the main structure is largely destroyed. One account says the site covers about 50,000 square metres and that five blocks were affected. We could only see that detail in a single report and have not independently verified it.

Why Could the Plant Stay Shut for 1–2 Years?
The company has not published a detailed reconstruction plan in the accounts we reviewed, so the reasons are our inference. Pharmaceutical plants rely on controlled production areas, validated equipment, utilities and quality systems, and these usually have to be rebuilt, re-qualified and re-inspected before manufacturing resumes. If the main structure is largely destroyed, as reported, a long outage is plausible. Whether any production can be moved to other sites has not been stated.
The timeline in the chart is the company’s own estimate as reported, and it may change once engineers assess the site and security conditions allow rebuilding.
Conflicting Accounts: Plant, Warehouse and Leadership
Not every account describes the target the same way. Ukrainian President Volodymyr Zelensky was quoted as saying Russia struck “an ordinary pharmaceutical warehouse” in Sumy and that one person was killed, while the company describes a manufacturing plant. The company is also reported to have a separate warehouse in Kyiv, which was damaged in April 2025. Some reports name Rajeev Gupta as the head of the group, whereas the quoted co-founder is Sanjeev Gupta. We use the name as provided in the Times of India interview and do not resolve the difference.
Russia’s defence ministry has said it will continue to strike what it calls military and military-industrial facilities. We did not find a Russian statement on this particular strike. After the April 2025 Kyiv warehouse incident, Russia denied attacking the site and suggested it could have been a Ukrainian missile, so the two sides’ accounts of such incidents have differed before. The “targeted” description in this report is the company’s view.
About Kusum Healthcare
Kusum Group is reported to have started in 1994 as a distributor of Indian medicines in Ukraine, began manufacturing under its own brands in the early 2000s and opened the Sumy plant in 2009. Reports say it makes more than 50 generic products sold in at least nine countries, including Ukraine, Uzbekistan, Kazakhstan and the Philippines, and that it is the largest Indian pharmaceutical company in Ukraine with a market share above 3%. Those figures are company-reported or from single accounts, and the cardiology and gastroenterology focus was also reported by only one source. The plant is said to have kept producing throughout the war until this strike.
Impact on Medicine Supply and Indian Pharma
The effect on supply has not been quantified. Ukrainian patients who rely on Kusum brands may need substitutes if stock runs low, and it remains unclear how the damage will affect sales in the other markets the company serves. For India’s pharmaceutical industry, which exports widely, the strike is a reminder of operational risk in conflict zones. Industry bodies such as Pharmexcil track export trends, and the Ministry of External Affairs handles consular matters for Indian nationals abroad, though we did not see a statement from it on this incident.
Attacks on health-related infrastructure are tracked by the Surveillance System for Attacks on Health Care in conflict zones. Closer to home, our recent coverage of the TIL Healthcare Sri City boiler explosion, the Maharashtra FDA action on a Cipla warehouse, the Bayer Ohio plant investment and the PRIP scheme for pharma and medtech R&D shows how plant safety, regulation and investment shape the sector.
What Is Not Yet Known
- Final casualty figures, including how many were injured and their condition.
- An independent damage assessment and whether the one-to-two-year estimate holds.
- Whether production will shift to other sites and how supply to patients will be maintained.
- Any response from Russia on this strike, and any statement from the Indian government.
Our Assessment
In our assessment, the loss of a long-running Indian-owned plant in a war zone is significant for both Ukrainian medicine supply and Indian companies with overseas manufacturing. The one-to-two-year estimate should be read as a planning figure from the company, not a forecast, because rebuilding depends on security, insurance and regulatory re-approval. Numbers on losses and plant size should be treated as preliminary until the company or authorities publish them.
