Tonbo Imaging India Limited’s working-capital days hit 517

Tonbo Imaging India Limited’s working-capital days rose to 517 in Fiscal 2026 from 152 in Fiscal 2024 as cash was committed to inventory, receivables and a six-to-24-month production cycle. Tonbo also reported negative operating cash flow of Rs 63.216 crore in Fiscal 2026, after an outflow of Rs 316.119 crore in Fiscal 2025.

Why did Tonbo’s working-capital days reach 517 in Fiscal 2026?

Tonbo’s working-capital days reached 517 in Fiscal 2026 because working capital expanded while revenue recognition remained concentrated in the second half of the financial year. The measure increased by 237 days from 280 days in Fiscal 2025 and by 365 days from 152 days in Fiscal 2024. Working capital, calculated as total current assets minus total current liabilities, was Rs 393.557 crore at March 31, 2026, compared with Rs 240.235 crore a year earlier and Rs 55.700 crore at March 31, 2024.

The calculation reflects funding required before customer payment is received. Tonbo must finance raw materials immediately before production, long-lead-item inventory, finished goods awaiting customer acceptance and trade receivables after delivery. Manufacturing from purchase-order receipt to the final product typically takes six to 24 months, depending on product complexity, followed by two to eight weeks for delivery and customer acceptance. This sequence can extend the period between a confirmed order and cash collection.

What changed in Tonbo’s inventory and receivables?

Inventory was the principal balance-sheet increase in Fiscal 2026, rising to Rs 219.485 crore from Rs 111.144 crore in Fiscal 2025, an increase of Rs 108.341 crore. Trade receivables were broadly unchanged at Rs 211.663 crore at March 31, 2026 from Rs 210.312 crore a year earlier, but remained Rs 118.020 crore above the Rs 93.643 crore reported at March 31, 2024. Inventory and receivables together totalled Rs 431.148 crore, or about 93% of total current assets of Rs 464.273 crore at March 31, 2026.

Tonbo attributed the Fiscal 2026 inventory increase primarily to the deferment of a significant export order to Fiscal 2027 because of logistical disruptions arising from the West Asia crisis. The deferment also affected revenue recognition in Fiscal 2026. The disclosed mechanism is that materials and work in progress remain funded by Tonbo if production, shipment, customer acceptance or revenue recognition moves beyond the expected period.

The position changed again in the three months ended June 30, 2026. Inventory rose to Rs 319.633 crore, Rs 100.148 crore above the March 31, 2026 balance, while receivables fell to Rs 96.853 crore. Tonbo says the resulting 1,454 working-capital days are not directly comparable with annual figures because they use a 91-day period and revenue is cyclically concentrated in the second half. The quarter-end measure nevertheless shows the effect of substantial inventory alongside lower recognised revenue.

How has Tonbo funded its working-capital requirement?

Tonbo has met its working-capital requirement through internal accruals and bank working-capital facilities, with internal accruals providing the larger disclosed portion in Fiscal 2026. Of Rs 393.557 crore of working capital at March 31, 2026, Rs 277.493 crore was funded through internal accruals and Rs 116.064 crore through current borrowings. In Fiscal 2025, the corresponding figures were Rs 162.100 crore of internal accruals and Rs 78.135 crore of current borrowings.

Negative net cash flow from operating activities makes this funding mix material. Tonbo reported negative operating cash flow of Rs 63.216 crore in Fiscal 2026, following a negative Rs 316.119 crore in Fiscal 2025. Tonbo states that continued deterioration in working-capital efficiency and negative operating cash flow could increase borrowing requirements and create liquidity pressure. A reduction in that pressure would depend on inventory conversion, customer acceptance, cash collection and supplier-payment timing relative to funds committed before payment.

Tonbo must also furnish performance bank guarantees when purchase orders require them. These guarantees typically equal 3% to 5% of contract value and have a tenor of one to five years, covering execution and warranty periods. Outstanding guarantees rose to Rs 25.872 crore at March 31, 2026 from Rs 19.451 crore at March 31, 2025 and Rs 15.390 crore at March 31, 2024; they reached Rs 31.254 crore at June 30, 2026. Guarantee requirements can add to funding needs separately from inventory and receivables.

What could increase Tonbo’s liquidity requirement further?

Tonbo’s liquidity requirement could rise if billing or settlement is delayed, trade receivables are not collected on time, inventory or work in progress increases, supplier payments accelerate, or performance-guarantee requirements rise. Tonbo also identifies unforeseen delays, cost overruns, regulatory changes, customer and supplier term revisions, technological changes and economic conditions as factors that can change the amount and timing of working-capital needs. These factors matter because the six-to-24-month production period requires cash outlays before customer payment.

Execution outcomes in Tonbo’s order book are another factor. At June 30, 2026, Tonbo had 36 firm orders valued at Rs 314.240 crore, comprising 30 domestic orders worth Rs 231.872 crore and six overseas orders worth Rs 82.368 crore. A firm order is contractually confirmed by the customer, formally accepted by Tonbo and supported by binding documents such as an executed contract or purchase order. Tonbo states that income expected from the order book may not be realised on time or result in profit.

Two contracts valued at Rs 28.083 crore were cancelled in Fiscal 2025 and Fiscal 2026 because Tonbo delayed development of a product with a sizeable research-and-development component beyond the customer’s specified timeline. If an order is cancelled after production costs are incurred, actual costs may exceed the agreed work and may not be recovered through termination payments. Tonbo said no prolonged-payment instance affected its business, results of operations, cash flows or financial condition in the three months ended June 30, 2026 or the preceding three fiscals, but it gave no assurance that this would continue.

Conclusion

Tonbo’s 517 working-capital days in Fiscal 2026 reflect a balance-sheet structure in which inventory and receivables absorbed Rs 431.148 crore while production to customer payment can extend from six to 24 months, followed by delivery and acceptance. Negative operating cash flow of Rs 63.216 crore in Fiscal 2026, although lower than the Rs 316.119 crore outflow in Fiscal 2025, shows the relevance of internal accruals, current borrowings and bank facilities to funding operations.

The disclosed markers to watch are conversion of Rs 319.633 crore of inventory at June 30, 2026, collection of Rs 96.853 crore of receivables and the execution timing of the Rs 314.240 crore firm order book. Tonbo has stated that the export order deferred to Fiscal 2027 contributed to Fiscal 2026 inventory, making its execution and revenue recognition relevant to whether working-capital intensity moderates.
