Fitch Ratings has affirmed GridLiance West, LLC's (GLW) Long-Term Issuer Default Rating (IDR) at 'A-'.

The Rating Outlook is Stable. GLW's ratings reflect its low business risk as a regulated electric transmission utility operating under the Federal Energy Regulatory Commission (FERC) within a constructive regulatory framework.

Environmental permitting delays have shifted forecast capex timing. Fitch does not expect this to result in material incremental capex. Fitch expects leverage to remain elevated during the 2027-2028 construction period and to improve as projects enter service. Fitch expects equity support from parent NextEra Energy, Inc. (NEE; A-/Stable) to back GLW's capex plan and help moderate leverage.

After debt repayment at NextEra Energy Transmission Holdings, LLC (NETH; not rated), an intermediate holding company within NEE, Fitch now assesses GLW under its Parent and Subsidiary Linkage Rating Criteria based on links with parent NEE. Accordingly, GLW's Standalone Credit Profile (SCP) is the same as NEE.

Key Rating Drivers

Permit Delays Shift Capex Timing: Fitch does not expect GLW's capex shift for the Core Upgrade and Beatty projects to materially affect leverage, as total spending is unchanged. GLW expect about $1.6 billion of capex in 2024-2028, with about $515 million invested through 2025, the remainder funded under its authorized capital structure. Slower environmental permitting by the Bureau of Land Management pushed projected completion to 1H28 from YE 2027 and deferred some capex into 2028.

Fitch views GLW's sizable capex program as manageable, supported by its low business risk, constructive regulation and expected support from ultimate parent NEE. The project should drive meaningful rate base growth and benefits from an authorized 10.6% ROE, 60% equity capitalization and supportive mechanisms, including CWIP, AFUDC and asset abandonment provisions. Fitch views execution risk as moderate, as cost overruns, delays and/or adverse regulatory developments could weaken GLW's credit profile, although parental equity support should help mitigate pressure on credit metrics.

Improving Credit Metric: Fitch expects delays in obtaining environmental approvals to shift capex, easing previously anticipated pressure from elevated spending on credit metrics. With the major construction now expected to begin in 2027, funding needs are spread more evenly across 2026 through 2028, rather than concentrated in 2025 and 2026 as previously forecast. Fitch forecasts leverage at about 4.0x on average and within the negative rating sensitivity throughout the forecast period, supported in part by the CWIP mechanism, which allows interim cost recovery during the elevated capex period.

Supportive Regulatory Framework: GLW benefits from a constructive regulatory framework under its FERC-approved tariff structure, which supports cash flow stability through formula-based rate updates, subject to an annual true-up. The framework includes recovery mechanisms for construction-related costs, including CWIP and start-up regulatory assets. In addition, GLW is permitted to recover 100% of prudently incurred costs associated with Core Upgrade and Beatty projects abandoned for reasons beyond its control.

Beneficial NEE Ownership: Fitch views GLW's ownership by ultimate parent NEE as a credit positive. NEE's strong credit profile, financial flexibility, and development expertise support GLW's competitive position and growth strategy. Fitch expects GLW to benefit from indirect equity support from NEE as it funds its sizable capex program.

Low-Risk Regulated Transmission Business: GLW has a low business risk profile as a FERC-regulated electric transmission utility operating within CAISO (A+/Stable). The company has no material exposure to volumetric risk, commodity price movements, or customer concentration. Under its FERC-approved tariff, GLW recovers its cost of service, including a return on investment, from transmission customers across the CAISO region. Revenue collection through CAISO further reduces counterparty and payment risk.

Further Growth Opportunities: Fitch expects GLW to pursue additional transmission investment opportunities. These projects are aligned with California's clean energy objectives and are intended to support renewable development along the California-Nevada border. Fitch believes demand for these projects will remain supported by favorable policy and infrastructure needs. Continued constructive FERC rate-making will be important to maintaining GLW's credit profile as growth capex increases.

Parent and Subsidiary Linkage: GLW is an indirectly owned subsidiary of NEE. Following the repayment of NextEra Energy Transmission Holdings, LLC's (NETH; not rated) debt, Fitch now assesses parent-subsidiary linkage between GLW and NEE. Fitch determines NEE's Standalone Credit Profile (SCP) based on consolidated metrics. GLW's SCP is the same as NEE's. If GLW's SCP were to become stronger than NEE's, Fitch would evaluate GLW under the stronger subsidiary/weaker parent framework. In this scenario, Fitch would limit the rating differential between NEE and GLW to two notches.

Peer Analysis

GLW's IDR reflects its low business risk profile as a regulated electric transmission utility, with no exposure to commodity prices or volumetric risk. This assessment also considers its ownership by a strong ultimate parent, NEE (A-/Stable). Within Fitch's coverage universe, GLW's closest peers include AEP Transmission Company, LLC (AEPT; A-/Stable) and Mid-Atlantic Interstate Transmission LLC (MAIT; A/Stable). Like its peers, GLW is regulated by the Federal Energy Regulatory Commission (FERC), which Fitch considers more favorable than state regulation.

Fitch projects that GLW's FFO leverage will remain elevated till the projects reach COD in 2028, compared to AEPT's projected average leverage of 4.3x over the same period. Although smaller than its peers, GLW's significant capital expenditure plans are expected to exert pressure on its credit metrics in the near term relative to AEPT and MAIT. FFO leverage is anticipated to peak at 5.1x in 2027, before improving to 4.2x by 2028, aligning with its peers.

Fitch's Key Rating-Case Assumptions

A constructive regulatory environment at the FERC;

Continued ROE of 10.6% for rate-making and CWIP incentive related to Core Upgrade Project;

Distributions and/or parental contributions managed to maintain authorized regulatory capital structure;

Capex as per management estimates over 2026-2028 funded in line with the authorized capital structure with an indirect equity support from NEE;

The Beatty and Core Upgrade projects are in service by 2028 and are included in rates accordingly;

Continuance of existing authorized ROE and capital structure for the new projects;

Interest Rate consistent with Fitch Global Economic Outlook.

Corporate Rating Tool Inputs and Scores

Fitch scored the issuer as follows, using our Corporate Rating Tool (CRT) to produce the Standalone Credit Profile (SCP):

Business and financial profile factors (assessment, relative importance): Management (bbb, Lower), Sector Characteristics (a, Higher), Market and Competitive Positioning (bbb+, Lower), Diversification and Asset Quality (bbb, Moderate), Company Operational Characteristics (bbb+, Moderate), Profitability (bbb+, Moderate), Financial Structure (a-, Higher), and Financial Flexibility (a-, Moderate).

The quantitative financial subfactors are based on custom CRT financial period parameters: 100% weight for the forecast year 2028

The Governance assessment of 'Good' results in no adjustment.

The Operating Environment assessment of 'aa-' results in no adjustment.

The SCP is 'a-'.

To derive the IDR:

?Application of Fitch's Parent Subsidiary Linkage Rating Criteria results in the parent and subsidiary having the same credit profile.?

RATING SENSITIVITIES

Factors That Could, Individually Or Collectively, Lead To A Negative Rating Action/Downgrade:

Any major time and cost overrun at GLW's projects such that FFO leverage does not return to below 4.8x in 2028;

A meaningful deterioration in the regulatory environment at the FERC;

Sustained FFO Leverage weaker than 4.8x beyond 2028;

Factors That Could, Individually Or Collectively, Lead To A Positive Rating Action/Upgrade:

A positive rating action is unlikely in the near term given the elevated leverage expected during the project execution phase.

Liquidity and Debt Structure

Fitch views GLW's liquidity as adequate. In August 2025, the company entered into a new $500 million revolving credit facility maturing in August 2030, replacing its prior facility and providing funding for working capital and capex needs. As of Dec. 31, 2025, GLW had net liquidity of $228.6 million, consisting of $25.1 million of cash and cash equivalents and $203.5 million of revolver availability.

GLW intends to replace this facility with long-term debt upon completion of the capital expenditures in 2028. Additional long-term debt is also expected to be issued to execute the capital expenditure plans. As of FYE 2025, GLW has no other long-term debt outstanding. Likely equity support from NextEra Energy, Inc. (NEE) would further support GLW's liquidity during the capital expenditure execution phase.

Financial covenants for GLW include a maximum debt-to-total capitalization covenant of 65% and a minimum interest coverage of 2.5x. Fitch expects continued compliance with these covenants.

Issuer Profile

GridLiance West LLC (GLW: A-/Stable) is a transmission-only utility company subject to rate regulation with operations within the California Independent System Operator Corp (CAISO) in southwest Nevada.
