Inventory and biomass at closing

Federal and state law current as of September 2026 — verify with counsel.

Cannabis inventory at closing is counted jointly, reconciled to the state track-and-trace system, and priced under a formula written into the purchase agreement. The usual formula is a target inventory value with a dollar-for-dollar price adjustment above or below it. Only saleable, tested, unexpired product counts. Inventory moves to the buyer only through the state system, after regulator approval.

Key takeaways

  • A common structure is an inventory target with a tolerance band; one 2021 Colorado asset purchase filed with the SEC set a $65,000 target, about two weeks of stock, with adjustment only beyond $6,500 either way.
  • Valuation basis matters: seller's cost, current wholesale value, and retail value can differ by a factor of two or more for the same package.
  • Colorado's state average market rate for retail flower was $607 per pound for April to June 2026, down from $1,721 in early 2021, so old cost figures can overstate stock value.
  • California requires physical inventory to be reconciled to the tracking system at least every 30 days, which gives buyers a record to test before the closing count.
  • In an asset sale, inventory is a Class IV asset on IRS Form 8594, and the amount allocated to it is ordinary income to the seller.

What counts as inventory in a cannabis deal

Inventory means every tagged plant and package under the licence, plus untracked supplies. It falls into groups that are priced differently:

CategoryExamplesUsual treatment
Finished goodsPackaged flower, pre-rolls, vapes, edibles on the shelf or in the vaultCounted and priced; the core of a retail inventory adjustment
Work in processDrying or curing flower, bulk oil, unpackaged ediblesPriced at cost to date or an agreed bulk rate
Biomass and trimFresh-frozen material, trim held for extractionPriced per pound at a current market rate; quality and age matter a lot
Living plantsClones, vegetative and flowering plants, mother stockNegotiated per plant or at cost; often low value
Non-cannabis suppliesPackaging, hardware, nutrients, accessoriesAt cost, usually with a cap

Genetics are a separate question. Mother plants are inventory, but a strain library with brand value is closer to intellectual property and is dealt with elsewhere in the agreement.

How is closing inventory priced?

There are three common structures.

1. Target, or peg, with adjustment. The price assumes a normal level of stock. If the closing count is above the target the price rises, and if below it falls. Cannabis deal lawyers describe this as one of the most common purchase price adjustments, because it assures the buyer of enough stock to keep trading.

A public example: in a June 2021 Colorado asset purchase filed with the SEC, the target was $65,000, described as roughly two weeks of marijuana inventory at wholesale value. The count began the day before closing. The price moved only if the count differed from the target by more than $6,500. Inventory had to be unexpired, of merchantable quality, and free of pests, mould, and impermissible contaminants.

2. Price plus inventory. Common in small retail deals. The headline price excludes stock, and the buyer pays for the count at closing, usually at the seller’s cost and often subject to a cap so the seller cannot overstock.

3. Part of net working capital. Larger deals fold inventory into a working-capital target with receivables and payables. The same logic applies, across more line items.

Which value: cost, wholesale, or retail?

The valuation basis is where most disputes start. For the same package:

  • Seller’s cost is what the seller paid or spent to produce it. It is verifiable from invoices, but it can be above today’s market if prices have fallen.
  • Current wholesale value is what it would cost the buyer to replace it today.
  • Retail value is never the right basis for a buyer, because it includes margin the buyer has yet to earn.

Falling prices make this a live issue. Colorado’s official average market rate for retail flower was $607 per pound for April to June 2026, against $1,721 in early 2021. A seller carrying flower at last year’s cost may be holding stock that is worth less than its book value. A fair clause uses the lower of cost and current replacement value. Market data sources are covered in how oversupply and price compression affect value.

Illustrative adjustment. Target inventory is $180,000 at cost. The closing count at cost is $212,000. Of that, $14,000 is product older than the agreed age limit and $6,000 does not reconcile to the tracking system, so both are excluded.

ItemAmount
Counted at cost$212,000
Less aged product excluded($14,000)
Less unreconciled product excluded($6,000)
Eligible inventory$192,000
Target$180,000
Price increase to seller$12,000

What is excluded from the count

Write the exclusions into the agreement, not the closing-day conversation:

  1. Expired product, and product within a set number of days of expiry. Colorado ties expiration dates to stability testing at intervals such as 6, 9, and 12 months; other states set their own rules.
  2. Product older than an agreed age, often 90 to 180 days for flower at retail.
  3. Anything that failed testing, lacks a required test, or is on administrative hold or recall.
  4. Packages that cannot be matched to the state system by tag, weight, or count.
  5. Damaged, opened, or returned goods and display samples.
  6. Quantities of any one item above an agreed number of weeks of sales.

The closing count

  1. Freeze the record. Close open manifests, finish pending adjustments, and record waste before the count. Unexplained corrections just before closing draw attention from buyers and regulators.
  2. Count together. Two-person teams, one from each side, count against the active inventory report. Large cultivation and manufacturing sites need one to two days, so start before closing day.
  3. Reconcile. Every variance is either corrected in the system by the seller with a documented reason or excluded. California licensees must already reconcile physical stock to the system at least every 30 days; ask for those records in diligence. See verifying revenue with track-and-trace data.
  4. Sign the count sheet. Both sides sign. It feeds the funds-flow memo.
  5. True up. Agreements usually give the buyer 30 to 90 days to deliver a final statement, with a dispute process that ends at an independent accountant.

Getting inventory into the buyer’s name

Tagged product belongs to a licence number in the state system. It does not move because a bill of sale says so.

The mechanics by structure are set out in track-and-trace systems and transactions. The buyer must not take possession or control of product before approval, even if the price has been agreed. Where closing happens in stages, the inventory payment is normally held until the transfer is recorded; see staged closings and escrow pending approval.

Cultivation and extraction: crops in progress

A retail count is a snapshot. A grow is a moving target, because plants gain value every week and the harvest date may fall either side of closing. Points to settle in the agreement:

  • Who owns the crop in the ground. Either the buyer pays for plants at a formula, or the seller is paid a share of the first harvest after closing. The second approach looks like an earn-out and may need regulator disclosure as a financial interest; see earn-outs in cannabis deals.
  • Biomass quality. Price per pound varies with potency, age, and storage. Tie the price to test results and a dated market reference, not to a number agreed months earlier.
  • Crop failure between signing and closing. Risk of loss stays with the seller until closing unless the agreement says otherwise. Check that crop or stock insurance exists; many cannabis policies exclude living plants.
  • Excise and cultivation taxes. Some states tax the first transfer from a grower. Confirm whether moving inventory to a new licence is a taxable transfer in your state.

Tax treatment of the inventory payment

In an asset sale, inventory is a Class IV asset on IRS Form 8594. Consideration is allocated to it, at fair market value, before equipment and goodwill. For the seller, the amount allocated to inventory is ordinary income, not capital gain. For the buyer, it becomes cost of goods sold as the stock is sold, which is one of the few costs that remains deductible for an adult-use operator under 280E. The two sides therefore tend to agree on inventory value more easily than on other classes. See purchase-price allocation in cannabis deals.

Frequently asked questions

Is inventory included in the purchase price of a cannabis business?

It depends on how the offer is written. Many small retail deals quote a price plus inventory at cost, counted at closing. Larger deals include a normal level of inventory in the price and adjust up or down against a target. A letter of intent should say which approach applies, because the difference can be several hundred thousand dollars for a cultivator or manufacturer.

How are growing plants valued at closing?

There is no standard. Common approaches are accumulated direct cost to date, a fixed amount per plant by growth stage, or expected yield times an agreed price less the cost to finish. Buyers often pay little for immature plants because crop risk passes to them. Whatever the method, plant counts must match the tagged plants in the state tracking system.

Can the buyer refuse old or failed product?

Yes, if the agreement says so, and it should. Typical exclusions are expired product, packages past an agreed age, anything that failed or lacks required testing, product on administrative hold, damaged or recalled goods, and items that do not reconcile to the tracking system. Excluded stock stays with the seller, who must sell it before closing or destroy it under state waste rules.

Can the seller sell off inventory before closing to take cash out?

An ordinary-course covenant and an inventory target are designed to prevent that. If stock falls below the target at closing, the price drops by the shortfall. Heavy discounting before closing also damages margins and customer expectations, so buyers usually add a covenant against unusual promotions between signing and closing.

What if the business being sold loses its licence before the inventory transfers?

Inventory held under a cancelled or expired licence generally cannot be sold or transferred and may have to be destroyed. That is why the seller must keep the licence renewed and in good standing until the regulator approves the change, and why buyers avoid structures with a gap between the old licence ending and a new one starting.
