Inventory Related Analysis

Inventory Related Analysis

NIU ended FY2025 with ¥652.6M of inventory on the balance sheet — flat YoY in nominal terms but 66% above the FY2023 trough of ¥392.8M, against a management guide that calls for FY2026 unit sales to grow 40–60% to 1.7–1.9M units. That juxtaposition makes inventory the single most decision-relevant line in this turnaround. The bull read is that NIU pre-built the seed-corn for a credible operating-leverage breakout while the bear read is that another year of write-downs above ¥80M would re-classify the FY24 build as strategic error — exactly the watchpoint forensics flagged. This tab decomposes the level, composition, funding, FY26 sizing, and channel-inventory question so the reader can hold both reads at once and watch the right prints to resolve them.

Bottom Line

Layer 1 — The Balance Sheet Line Itself

NIU discloses inventory turnover days in plain text in the 20-F: "Our inventory turnover days were 73, 71 and 74 for 2023, 2024 and 2025, respectively" (FY2025 20-F, business.txt line 187, using average inventory ÷ COGS × days). The ending-balance computation used by the forensics tab gives a slightly different series (71 / 85 / 69 for FY23/FY24/FY25) because FY24 absorbed a step-function inventory build at year-end that smoothed away on the average-basis denominator. Both methods agree the FY25 turn velocity is structurally elevated versus NIU's own pre-FY22 average of 30–45 days.

Three regime breaks matter on this chart. (1) FY22 lithium shock: inventory ballooned from ¥270M to ¥417M as carbonate prices spiked above ¥500k/t and zero-COVID lockdowns crushed sell-through — DIO jumped from 34 to 61 days. (2) FY24 over-build: inventory stepped from ¥393M to ¥649M (+65% YoY) as the company staged product for a sales push that did not materialize at full margin; ending-basis DIO hit 85 days. (3) FY25 "flat with composition shift": nominal inventory was almost unchanged (¥649M → ¥653M), but a ¥89M write-down was absorbed alongside what the cash-flow statement shows as a ¥89.5M gross inventory build — i.e., kick-scooter SKUs were purged and premium-China SKUs were rebuilt underneath the headline.

The Q3 FY25 quarter-end balance was ¥676.0M (transcript balance sheet, line 379), the highest in NIU's history, before drawing down to ¥652.6M at year-end as the September GB17761-2024 pre-buy wave shipped through. That intra-year peak is the cleanest single signal that FY25 sell-in was regulator-paced, not order-book-paced.

Layer 2 — The Write-Down History

Inventory write-downs appear in the OCF reconciliation as a non-cash add-back. The two consecutive prints — ¥30.0M in FY24, ¥89.2M in FY25 — are the most concrete piece of composition evidence on disk. The FY25 line equals 13.7% of ending inventory and 2.1% of revenue.

Management's verbatim FY25 attribution is in the Q4 FY25 transcript line 183: the Q4 cost-per-scooter spike to ¥3,317 (+4.8% YoY) was "mainly due to provisions for slow-moving inventory and higher freight costs in international markets, partially offset by cost-reduction initiatives in China market." The Q1 FY25 transcript line 167 attributes the early-year GM dip to international "inventory write-downs" specifically on kick-scooters. The composition signal is therefore narrower than the headline suggests: the ¥89M write-down is concentrated in the international kick-scooter line that printed only ¥266M of FY25 revenue, not the ¥3,630M China premium-scooter line that absorbed the inventory rebuild.

A simple corroboration: in Q1 FY2026 (per management's prior commentary on international ASPs), international revenue per e-scooter reportedly recovered from ¥2,962 to roughly ¥3,716 after the kick-scooter SKU cleanup — directionally consistent with the FY25 ¥89M provision being a cleanup event, not an early signal. The forensics tab tripwire is a second consecutive year of write-downs above ¥80M — if the FY26 20-F prints ¥80M+ again on a kick-scooter line that is supposed to be cleaned up, the read flips from "cleanup" to "structural impairment."

Layer 3 — How the Inventory Is Funded

Inventory cannot be read in isolation from how it is paid for. The FY25 cash-flow reconciliation (FY2025 MD&A line 838) shows ¥89.5M of inventory build was a working-capital drag — and ¥89.2M of write-downs were added back as non-cash — but the cash needed to put product on the shelf was effectively financed by supplier credit, not retained earnings. Accounts payable plus notes payable (bank acceptance drafts) reached ¥1,098M at FY25, equal to 168% of inventory.

The financing arithmetic: DPO (119 days, management average basis) minus DIO (74 days, management average basis) equals 45 days of free supplier financing on the inventory leg alone. The inventory is held, but the cash for it is borrowed from suppliers through stretched payment terms and ¥394M of bank acceptance notes — short-dated rollable instruments that did not exist on the FY23 balance sheet.

Sensitivity that matters. If DPO compresses 30 days back toward sector norms of 60–80 days while inventory holds at ¥653M, the cash drawdown is approximately ¥285M — close to 80% of FY25's reported ¥353M operating cash flow. That sensitivity, not the inventory line itself, is the highest-impact single number on this page.

This is the cross-read the forensics tab flags but does not size. Notes payable (¥394M) rolling forward is the single most repeatable lever NIU has — and the most fragile if supplier confidence wavers because of an inventory miss.

Layer 4 — The FY26 Sizing Test

The cleanest single test of management's "prudent inventory" framing: take the FY25 inventory-per-unit-sold ratio and apply it to the FY26 guide. FY25 inventory of ¥652.6M against 1.192M units = ¥548 of inventory per annual unit sold (broadly, what the company holds per delivered scooter through a year).

The arithmetic forces a binary read. Either:

• Inventory grows another ¥280–388M in FY26 to support the guide, in which case the FY26 OCF gets a ¥280–388M working-capital drag that would consume 79–110% of the reported FY25 ¥353M OCF, unless payables and customer advances ratchet up in lockstep (a continuation of the balance-sheet-runway pattern the forensics tab calls out); or
• Inventory holds flat near ¥653M while DIO compresses from 74 days to roughly 45 days, a productivity gain not yet evidenced and not historically achieved at NIU since the FY20 pre-shock low of 27.5 days.

Management's stated framing — "we keep an optimal inventory level" — is closer to Door #1: they are saying the build is sized to the guide. The OCF implication has not been modelled by sell-side and is not in the FY26 outlook commentary. Reasonable midpoint: a ¥330M FY26 inventory build is the implied price of meeting the guide, partially offset by another ¥300–500M of customer-advance and supplier-credit expansion if the FY24-FY25 pattern repeats.

Layer 5 — Channel Inventory (Triangulation, Not Verdict)

Reported inventory is what sits in NIU's own warehouses and in-transit; it does not include units already sold to franchisees that have not reached end users. Those off-balance-sheet "channel inventory" units cannot be observed from the financials. Three indirect data points define the tension.

The honest framing: signals 1 and 3 point at front-loading; signals 2 and 4 point at structural demand-pull through a growing franchise network. The on-disk data cannot resolve which dominates because the channel-inventory number is not reported. What would resolve it is Q2 FY26 (mid-August release) — the first quarter without a regulatory cliff in view. The variant-perception tab calls this exact point: Q1 FY26 prints with the CCC cliff still pulling forward; Q2 FY26 is the cleaner test.

What Would Change The Read

Reconciliation Notes And Material Limitations

A handful of definitional and disclosure boundaries should be made explicit so the reader can audit the numbers above.

Net read. The inventory line tells a self-consistent FY25 story: a kick-scooter cleanup was absorbed, a premium-China pre-build was staged, supplier credit financed both, and management is willing to size the balance sheet to the FY26 guide. The risk is not the ¥653M itself; it is the joint distribution of (a) another ¥80M+ write-down in FY26, (b) supplier-credit tightening pulling cash back, and (c) Q2 FY26 confirming channel-pull-forward rather than end-user-demand. Each of those three is testable on a defined calendar — May 18, mid-August, and the FY26 20-F — and each carries a quantified tripwire. The honest position for an underwriter is to grant management the size of the build but hold the cash-flow benefit in escrow until the next two prints corroborate the story.
