Cube Highways gets NHAI's WPI factor back to 1.641, locking in higher toll hikes.
NHAI restores original linking factor for all concession agreements, resolving legal uncertainty that could have trimmed annual toll increases by 5%.

- NHAI supersedes September 2025 circular, restores WPI linking factor to 1.641.
- Decision follows 29 June 2026 MoRTH memo, resolves Delhi HC stay uncertainty.
- Cube Highways' SPVs avoid ~5% annual toll hike cut; inflation-adjusted revenue trajectory preserved.
Why this matters
For an InvIT whose cash flows are indexed to inflation, the WPI factor is the single most important input after traffic volume. Restoring 1.641 prevents a compounding drag that would have reduced project returns over the remaining concession life. While the market had priced in a favourable outcome after the Delhi HC stay, the policy circular makes it permanent.
What we're watching
- Traffic trends on Cube’s remaining 26 road assets — toll revenue depends on both factor and volume.
- Any further litigation challenging the circular before courts.
- Cube's next distribution announcement — factor restoration supports DPS.
The full read
NHAI restored the WPI linking factor to 1.641 – the number that determines how much tolls go up each year. For Cube Highways, whose cash flows are tied to inflation, this removes a potential 5% annual drag on toll increases that the September 2025 circular would have applied. The market had largely priced in a favourable outcome after the Delhi High Court stay, but the policy circular makes it permanent, locking in a structural positive for the InvIT. The next challenge is traffic. With 26 remaining assets, volume growth will determine whether the factor benefit fully flows through. One concession expired in June, but on the rest the pricing tailwind is now secured.
Questions answered
- What exactly did NHAI change?
- NHAI restored the WPI linking factor to 1.641 from the 1.561 set in its September 2025 circular, meaning toll rates will increase by a factor based on WPI inflation instead of a lower factor.
- Why does this matter for Cube Highways?
- Cube's SPVs get toll revenue linked to WPI; a lower factor would have reduced annual toll increase by about 5%, compressing cash flows. Restoration removes that risk.
- Was this expected?
- The Delhi High Court had already stayed the lower factor in September 2025, so the policy circular formalizes the court's direction. The market had anticipated this.
- How does this affect distributions?
- Since toll revisions directly feed revenue, the restoration supports the sustainability of distributions, but actual payouts depend on traffic and costs.
- What remains uncertain?
- Traffic volumes, maintenance costs, and the risk of future policy changes. The factor itself is now settled, but other variables remain.
- How many assets does Cube Highways have?
- It had 27 road assets; one concession (Meerut–Muzaffarnagar) expired in June 2026, leaving 26 operating assets under the trust.
