Nextracker (NXT): Customer relationships that drive backlogged growth—and concentration risk

Nextracker monetizes by selling solar tracker systems and adjacent software to large-scale solar project developers and EPCs, combining hardware (trackers and foundations) with its TrueCapture energy-yield management software and long-term master supply agreements. Revenue derives from project-level system sales and multi-year framework deals (including volume commitment agreements), delivering high single-digit to multihundred-million dollar contracts and a backlog that underpins near-term topline visibility.

How Nextracker wins: product mix, contract posture, and where revenue concentrates

Nextracker’s operating model is straightforward: sell physical tracking systems at scale and layer software services that improve plant output and lock in aftermarket relationships. The company sells on both single-project purchase orders and through master/volume frameworks that allocate capacity across years. The corporate disclosures and relationship signals produce a coherent commercial profile:

  • Contracting posture: Nextracker operates a mix of project-level sales and framework and multi-year contracts (Volume Commitment Agreements) that repeat over time and shape backlog cadence.
  • Counterparty profile: The firm is a preferred supplier to very large EPCs, developers, and utilities, which organizes go-to-market around enterprise sales cycles and long procurement windows.
  • Geography and concentration: Nextracker is global but U.S. shipments dominate (about 69% of revenue in FY2025), with sales in more than 40 countries.
  • Commercial maturity and materiality: Relationships are mature and strategically material—loss of a leading partner would materially affect future project wins; project economics also produce contracts that can exceed $100 million for large deployments.
  • Revenue mix: Hardware trackers remain the core product, with software (TrueCapture) contributing recurring, higher-margin services over time.

Customer relationships, company-by-company

Below are the relationships disclosed in Nextracker’s public reporting and company news, summarized in plain English with source context.

Customer F

Customer F accounted for 14.0% of revenue in fiscal year 2025, making it one of Nextracker’s largest single customers in that period (Nextracker Form 10‑K, fiscal year ended March 31, 2025).

Customer A

Customer A represented 12.4% of revenue in FY2025 (and was larger in earlier periods, showing historical concentration) according to Nextracker’s fiscal 2025 10‑K filing (Form 10‑K, fiscal year ended March 31, 2025).

Customer G

Customer G made up 15.5% of revenue in FY2025, the single largest named customer percentage disclosed in the FY2025 10‑K (Nextracker Form 10‑K, fiscal year ended March 31, 2025).

Flex (FLEX)

Nextracker recorded a $15.5 million payment to Flex, TPG and related affiliates in fiscal 2025, presented as a financing activity on the consolidated cash flow statement (Nextracker Form 10‑K, fiscal year ended March 31, 2025).

PPC Renewables (PPCR)

Nextracker announced that its NX Horizon trackers will power the 550 MW Oricheio (“Ptolemaida”) solar PV park in Western Macedonia, owned by PPC Renewables and constructed by Terna SA; this is a large European utility-scale award announced on Nextracker’s investor site in March 2025 (Nextracker press release, March 2025).

Terna SA

Terna SA is listed as the EPC partner on the Oricheio Ptolemaida project, positioning Terna as the executing contractor for the 550 MW installation where Nextracker supplies trackers (Nextracker press release, March 2025).

ACCIONA Energia

Nextracker public communications note that the first scheduled deliveries from its Australian steel components facility include ACCIONA Energia’s 480 MWp Aldoga Solar Farm, establishing a manufacturing‑to‑project linkage in Australia (Nextracker press release, 2024).

JinkoSolar / Jinko Solar (U.S.) Industries Inc. (JKS)

Nextracker entered a multi‑year, gigawatt‑scale steel frame supply agreement with Jinko Solar (U.S.) Industries and announced related U.S. supply deals to increase local steel-frame capacity, signaling strategic supply-chain partnerships for module and frame components (MarketScreener coverage of Nextracker announcements, March 2026).

L&T

Nextracker (through its regional affiliate) secured a 2.25 GW smart tracker supply relationship with L&T for the ACWA Power consortium’s Bisha solar project, reflecting large project-level wins in the Middle East (MarketScreener coverage, March 2026).

What the relationship map implies for investors

The disclosures create a clear investment-relevant picture: Nextracker wins large, often repeatable contracts with enterprise customers and EPCs, but the revenue profile contains meaningful concentration. The three named customers (Customer G 15.5%, Customer F 14.0%, Customer A 12.4% in FY2025) together represent a substantial chunk of annual revenue and explain why management emphasizes maintaining strategic relationships with top EPCs and developers. At the same time, framework agreements and VCAs provide predictable multi-year demand that underpins Nextracker’s >$4.5 billion backlog and supports margin durability (Form 10‑K commentary).

Key investment implications:

  • Execution and supply‑chain risk are principal operational threats given large project size and the need for local manufacturing scale-ups (e.g., U.S. steel frame capacity and Australian component production).
  • Counterparty concentration is material: the loss or delay of projects with a top customer would have an outsized earnings impact.
  • Contract structure is favorable for revenue visibility since a mix of framework and long-term contracts reduces quarter-to-quarter volatility in new wins.

Next steps for allocators and operators

For portfolio managers, underwrite position sizing against two axes: concentration exposure to top customers and supply‑chain execution risk as factories scale. For operators and EPCs, the commercial takeaway is to treat Nextracker as a strategic, high‑volume supplier with integrated software that can be part of long-term plant performance contracts.
