Fusion CX Limited’s largest customer generated 25.48% of revenue

Fusion CX Limited derived 25.48% of revenue from operations in the three months ended June 30, 2026 from Customer 1, its largest customer. Fusion CX’s top 10 customers generated Rs 244.479 crore, or 49.84%, of quarterly revenue from operations of Rs 490.484 crore, making retention and renewal outcomes material to its revenue base.

How concentrated was Fusion CX’s June-quarter revenue?

Fusion CX’s June-quarter revenue was concentrated in Customer 1 and a group of 10 customers. Customer 1 contributed Rs 124.968 crore in the three months ended June 30, 2026, equal to 25.48% of revenue from operations. Customer 2, the next-largest account, contributed Rs 28.568 crore, or 5.82%, so Customer 1 generated more than four times Customer 2’s revenue contribution.

The top 10 customer group generated Rs 244.479 crore, leaving Rs 246.005 crore, or 50.16% of quarterly revenue from operations, from customers outside that group. Park West Professional Services was the only named company in the June 2026 table, contributing Rs 16.098 crore, or 3.28%; Fusion CX said customer names were not included where disclosure consents were unavailable.

How did Fusion CX’s customer concentration change over time?

Fusion CX’s top-10 concentration rose from 41.04% in Fiscal 2024 to 52.17% in Fiscal 2026, before declining to 49.84% in the three months ended June 30, 2026. Top-10 revenue increased from Rs 406.817 crore in Fiscal 2024 to Rs 948.499 crore in Fiscal 2026, while total revenue from operations increased from Rs 991.315 crore to Rs 1,818.238 crore over the same two fiscal years.

Customer 1 was the principal contributor to the higher concentration. Its revenue increased from Rs 142.225 crore in Fiscal 2024 to Rs 546.446 crore in Fiscal 2026, and its revenue share rose from 14.35% to 30.05%. Customer 1’s share was 25.48% in the June 2026 quarter, 4.57 percentage points below Fiscal 2026, although the June period covers three months rather than a full fiscal year.

Revenue below Customer 1 was distributed across smaller accounts. Customers ranked two through 10 each contributed between 1.52% and 5.82% of revenue from operations in the June 2026 quarter. Those nine customers collectively provided 24.36% of quarterly revenue, meaning the 49.84% top-10 share reflected both reliance on Customer 1 and reliance on a broader set of accounts.

Which customer contract terminations has Fusion CX disclosed?

Fusion CX disclosed contract terminations involving several customers listed in historical top-10 tables. In Fiscal 2024, Customer 3, Customer 7 and Customer 10 terminated contracts. In Fiscal 2025, Customer 7, Customer 9 and Customer 10 terminated contracts, according to the notes accompanying the respective customer tables.

For Fiscal 2026, Fusion CX disclosed terminations by Customer 7, Customer 6 and Propneu S.A. Propneu S.A. was the 10th-ranked Fiscal 2026 customer and generated Rs 32.893 crore, or 1.81%, of revenue from operations in that year. The June 2026 quarterly table also states that its Customer 10 had terminated its contract during Fiscal 2026, while the account generated Rs 7.465 crore, or 1.52%, in the reported three-month period.

The disclosures show that a top-10 position in one period does not establish continuing revenue in later periods. Fusion CX does not state the reasons for the terminations, the dates on which services ended, or whether revenue from the departed accounts was replaced. Maintaining the June-quarter concentration profile would therefore depend on retaining Customer 1 while replacing, renewing or expanding revenue from other accounts.

What could turn Fusion CX’s customer concentration into revenue pressure?

Fusion CX says the loss of a top customer, reduced requirements, delayed demand or failure to agree acceptable renewal terms could reduce demand for its services and affect sales volume and timing. The company also identifies disputes, customer financial hardship, bankruptcy, liquidation, facility shutdowns, labour strikes and customers selecting competitors as circumstances that could result in account loss.

Customer pricing and outsourcing decisions could also affect the concentrated revenue base. Fusion CX says customers may demand price reductions or move work in-house rather than outsource it. Since the top 10 group accounted for 49.84% of revenue from operations in the June 2026 quarter, an adverse change across that cohort would affect almost half of the reported quarterly revenue before any new business offset.

Geographic exposure is a further condition for maintaining customer revenue. Fusion CX reported that customers outside India accounted for 90.06% of revenue from operations in the three months ended June 30, 2026, while North America accounted for 79.56%. The company identifies geopolitical conditions, exchange-rate fluctuations, regulatory differences and economic developments in international markets as factors that could reduce demand, delay payments or affect customer financial stability.

Conclusion

Fusion CX’s reported revenue concentration increased as Customer 1’s share rose from 14.35% in Fiscal 2024 to 30.05% in Fiscal 2026, before standing at 25.48% in the June 2026 quarter. The top-10 group’s 49.84% quarterly contribution means revenue performance remains linked to a limited customer cohort, even though customers outside the group generated the remaining 50.16%.

The next disclosed matter to watch is Fusion CX’s ability to maintain historic business from key customers and reduce customer concentration, neither of which it says it can assure. Contract terminations reported across Fiscal 2024, Fiscal 2025 and Fiscal 2026 make customer renewals, pricing terms, new customer wins and replacement revenue relevant to the future concentration trend.
