Musti Group's own factory now produces 70% of its private-label food, driving margin to 44.6%

A buyer sits down to review the private-label program and the margin story has changed: the retailer now makes most of its own food in-house, and gross margin just climbed 30 basis points.

The production shift and what it bought

Musti Group, the Helsinki-based pet specialty chain operating across the Nordics and Portugal, reported that its own factory now produces 70% of Musti-branded food. The shift drove gross margin to 44.6% in the third quarter, up from 44.3% a year earlier, according to CEO David Rönnberg. For the first nine months of the fiscal year, gross margin reached 44.3%, mainly driven by the increased share of own-brand food production at the company's own factory.

The company is ramping wet food capacity at the same facility. Net sales for the quarter grew 17.7% year-over-year to €149.9 million, supported by the acquisition of Portuguese retailer ZU and like-for-like sales growth of 5.6% across all markets. ZU contributed €9.8 million to net sales in the quarter.

Musti's network grew to 542 stores and veterinary clinics, up from 425 in the same period last year. The company opened 45 new locations during the first nine months of the fiscal year and invested €21.5 million in tangible and intangible assets during that period, mainly for new stores, digital platform projects, and production machinery.

How in-house production changes the margin structure

Bringing private-label production in-house removes the contract manufacturer's margin from the cost structure. Musti's 30-basis-point gross margin improvement in Q3, and the similar lift across the nine-month period, came primarily from the increased share of own-brand food made at its own factory, the company said. The margin gain lands directly because the retailer keeps what it used to pay a third party to formulate, produce, and pack the SKU.

The move also gives the retailer control over production timing, batch sizes, and the ability to ramp new formats without negotiating minimums. Musti is now expanding wet food capacity at the facility, which suggests the company sees room to grow the private-label program into categories it previously couldn't economically produce in-house.

For a specialty retailer, the decision to own production infrastructure is a capital trade: spend on machinery and facility capacity up front in exchange for per-unit margin later. Musti's investments in tangible and intangible assets during the first nine months included production machinery as one of the primary uses. The payback shows up in gross margin, but the upfront cost sits in the balance sheet and ties up capital that could have gone to new stores or inventory.

What the play requires to work

The in-house production model scales only if the factory runs at high utilization. Musti operates 542 locations across five markets and reported 1.886 million customers (excluding the Baltics and ZU). That volume supports a factory running at 70% of the private-label program and justifies the capital to add wet food lines.

For a smaller chain, the numbers break differently. A regional operator with 15 stores doesn't move enough SKUs to keep a production line busy, and the per-unit cost of in-house manufacturing ends up higher than buying from a contract manufacturer who spreads fixed costs across multiple retail clients. The threshold sits somewhere between those endpoints, and it depends on how much of the assortment converts to private label.

Musti's model also assumes the retailer can sell the volume it produces. Like-for-like sales growth of 5.6% in Q3 and 3.9% for the nine-month period suggests the company is moving inventory, but a retailer that brings production in-house and then can't clear the SKUs ends up with both the manufacturing cost and the markdown.

The other risk is that quality control becomes the retailer's problem. A contract manufacturer with a recall eats the cost and manages the pull. When the retailer owns the line, the liability and the customer-service load both land on its desk. Musti hasn't reported a recall tied to its own production, but the risk shifts the moment production comes in-house.

Our read: the margin is real, but the model doesn't travel to most independents

Musti's 30-basis-point margin gain is a real number tied to a specific operational decision, and it shows up in a quarter where the company also integrated an acquisition and opened dozens of new locations. The in-house production model works at Musti's scale and works in categories where the retailer can standardize formulation across markets.

The play doesn't port to a single-location independent or even a small regional chain. The capital requirement, the utilization threshold, and the quality-control risk all argue against it until a retailer operates at a scale where it can keep a production line running and absorb a batch failure without it ending the quarter.

What does travel is the recognition that private-label margin is a function of who owns the production, not just the brand. A buyer negotiating with a contract manufacturer can ask what the per-unit cost would be at double the volume, or what it would cost to bring formulation in-house if the retailer hired the production expertise. Most won't make that jump, but knowing where the margin sits in the stack changes the negotiation.

The risk in Musti's model is that consumer preference shifts away from private label or that a competitor undercuts on price using a contract manufacturer with better utilization. The company is counting on controlling the line to give it enough margin room to hold price and enough flexibility to launch new SKUs faster than a competitor waiting on a third party. We'd watch whether the wet food ramp lands on shelves in volume and whether like-for-like sales growth holds as the private-label share grows.
