Stellantis Is Tearing Up Its US Marketing Partnerships. Here Is What That Signals

Stellantis has made sweeping changes to its US marketing partnerships, cutting agency relationships and restructuring how it manages media, creative, and commercial activity across its brand portfolio. The moves are significant not just for the agencies involved, but for what they reveal about how a major automaker is rethinking the role of external partners in a period of commercial pressure.

For anyone watching the partnership marketing space, this is worth paying attention to. When a company the size of Stellantis restructures its agency and partner ecosystem, it rarely happens in isolation. It reflects something deeper about how the business is measuring value, where accountability is being reassigned, and what kind of commercial relationships it actually wants.

What Actually Happened With Stellantis and Its US Partners?

Stellantis, the multinational automaker formed from the merger of PSA Group and Fiat Chrysler in 2021, has been under significant commercial pressure in the US market. Sales volumes declined, inventory challenges mounted, and the business faced criticism from dealers about pricing strategy and product positioning. Against that backdrop, the company began reviewing its marketing operations and agency relationships.

The result was a series of agency reviews and partnership changes affecting creative, media, and communications across brands including Jeep, Ram, Dodge, Chrysler, and Alfa Romeo. Some long-standing agency relationships were ended. Others were consolidated. The scale of the restructure put it among the more significant marketing partnership shakeups in the US automotive sector in recent years.

What makes this particularly interesting from a partnership marketing perspective is the framing. This was not positioned as a creative reset or a brand refresh. It was positioned, at least in part, as a commercial correction. Stellantis needed its marketing to work harder, and it decided the existing partner structure was not delivering that.

If you are interested in how partnership marketing structures are evolving more broadly, the Partnership Marketing hub covers the mechanics, strategy, and commercial logic behind how brands build and manage external partner relationships at scale.

Why Do Major Brands Restructure Their Marketing Partnerships?

I have been on both sides of this conversation. When I was running an agency, we lost a client relationship after what felt like a strong year of work. The work was good. The results were reasonable. But the client had changed its internal structure, brought in a new CMO, and that CMO had a different view of what a partner relationship should look like. We were not part of that view.

The lesson I took from that, and from watching dozens of similar situations play out over the years, is that partnership restructures at major advertisers are almost never purely about the quality of the work. They are about alignment. When a business changes its commercial priorities, its marketing partnerships need to change with them. If they do not, the partnership becomes a liability rather than an asset.

In the Stellantis case, several factors appear to have converged. A new CEO in Carlos Tavares had set aggressive cost targets across the business. The US market was underperforming relative to expectations. Dealer relationships were strained. In that environment, every function, including marketing, was under pressure to demonstrate clear commercial contribution. Agencies and partners that could not make that case were vulnerable.

This is not unique to automotive. I have seen the same dynamic play out in retail, financial services, and travel. When a business hits a rough patch, marketing partnerships get scrutinised in a way they rarely are during growth periods. The question shifts from “is this working reasonably well?” to “can you prove this is worth the money?”

What Does This Tell Us About How Brands Value Marketing Partnerships?

The Stellantis restructure is a useful case study in how large brands actually think about the value of their marketing partnerships, as opposed to how they talk about it in procurement documents and agency briefs.

There is a gap between the stated criteria for a marketing partnership and the real criteria. Stated criteria usually include things like strategic thinking, creative quality, data capability, and cultural fit. Real criteria, when commercial pressure arrives, tend to be simpler: can you demonstrate that your work is contributing to revenue, and can you do it in a language the CFO understands?

When I was growing the agency I ran from around 20 people to over 100, one of the things I pushed hardest on was commercial fluency. Not just marketing fluency. I wanted account teams who could sit in a room with a finance director and talk about contribution margin, not just click-through rates. That capability became a significant differentiator, particularly with clients who were under earnings pressure. It kept relationships intact through difficult periods that ended other agencies’ contracts.

The brands that are restructuring their partnerships right now are not necessarily doing so because the marketing was bad. They are doing so because the commercial conversation was not good enough. That is a different problem, and it has a different solution.

Understanding how co-marketing and partnership structures work at a foundational level helps here. Mailchimp’s overview of co-marketing is a useful reference point for the basics of how brands structure shared commercial relationships, even if the Stellantis situation is operating at a significantly larger scale.

How Does Agency Consolidation Affect the Quality of Marketing Output?

One of the arguments for consolidating agency relationships is efficiency. Fewer partners means fewer briefing cycles, fewer handoffs, fewer misalignments between creative and media. The integrated agency model has been sold on this basis for decades.

The counter-argument is that consolidation reduces specialisation. The best search agency is rarely the best creative agency. The best social partner is rarely the best programmatic partner. When you consolidate for efficiency, you often trade depth of expertise for simplicity of management.

I have managed both models and neither is categorically better. What matters is whether the structure matches the business’s actual marketing needs. A brand that does most of its volume through a small number of high-intent channels probably benefits from consolidation. A brand that needs genuine specialisation across a complex channel mix probably does not.

For Stellantis, the question is whether the consolidated model will actually produce better commercial outcomes, or whether it will produce simpler management with roughly equivalent results. Those are not the same thing, and the difference will only become visible over time.

There is also a talent dimension that rarely gets discussed in coverage of agency reviews. When a major advertiser restructures its partnerships, the best people at the outgoing agencies move on. Some go to the winning agencies. Many go to competitors or to in-house teams. The institutional knowledge that was built up over years of working on a brand does not transfer cleanly. That is a real cost, and it is almost never factored into the business case for a review.

What Can Smaller Brands Learn From the Stellantis Situation?

If you are running marketing partnerships at a business that is significantly smaller than Stellantis, which is most businesses, there are still useful lessons here.

The first is that the accountability conversation needs to happen before commercial pressure arrives, not after. I have watched too many agency relationships deteriorate because the measurement framework was never properly established at the start. When results disappoint, there is no agreed basis for evaluating whether the disappointment is the agency’s fault, the brief’s fault, the market’s fault, or the product’s fault. Everyone retreats to their own narrative and the relationship breaks down.

The second is that partnership structures should be reviewed on a regular cycle, not just when something goes wrong. A partnership that made sense three years ago may not make sense now. Markets change. Internal capabilities change. The competitive environment changes. A partnership that is not being actively evaluated is probably not being actively optimised either.

The third is that the best partnerships, whether with agencies, affiliates, or co-marketing partners, are built on commercial alignment rather than just contractual obligation. When both parties understand what success looks like in business terms, the relationship tends to be more productive and more resilient. Affiliate and partner program structures that embed commercial metrics from the start tend to outlast those built purely on activity-based fees. The approach Later uses in its affiliate program is a reasonable example of how commercial alignment can be built into the structure from the beginning, even at a relatively straightforward level.

Is the Automotive Industry Rethinking Partnership Marketing More Broadly?

Stellantis is not alone in reassessing how it structures its marketing partnerships. The automotive sector more broadly has been under pressure from multiple directions: the shift to electric vehicles, changing consumer purchase journeys, increased price sensitivity, and the ongoing challenge of managing dealer networks alongside direct-to-consumer ambitions.

Those structural pressures are forcing a rethink of what marketing partnerships are actually for. In the traditional model, the agency relationship was primarily about creative production and media buying. The brand set the strategy, the agency executed it, and success was measured in awareness and consideration metrics that were, at best, loosely connected to actual sales.

That model is under strain across the industry, not just at Stellantis. Brands want partners who can connect marketing activity to commercial outcomes in a more direct and defensible way. That is a reasonable demand, but it requires a different kind of partnership, one built on shared data, shared accountability, and a shared understanding of what the business is actually trying to achieve.

I judged the Effie Awards some years back, and the entries that stood out were almost always the ones where the commercial brief was crystal clear from the start. Not “build brand awareness among 18-34s” but “we need to shift X units in Y market by Z date, and here is the specific commercial problem we are trying to solve.” The best marketing partnerships I have seen operate the same way. The commercial objective is the anchor, and everything else is built around it.

BCG’s work on strategic alliances and commercial partnerships offers a useful framework for thinking about how large organisations structure relationships that are genuinely designed to create shared value, as opposed to relationships that look good on paper but do not deliver. Their research on turnaround partnerships highlights how commercial alignment at the outset determines whether a partnership survives pressure, which is precisely the dynamic playing out at Stellantis.

What Happens to the Agencies and Partners That Were Cut?

Losing a major client relationship is painful. I have been through it, and I have watched colleagues go through it. There is a period of genuine disruption, financial and operational, followed by a period of reassessment.

The agencies that tend to recover well are those that use the disruption as a forcing function. Losing a large client forces you to examine what you are actually good at, what kind of work you want to do, and what kind of clients you want to serve. That clarity, uncomfortable as it is to arrive at, tends to produce a stronger business over the medium term.

The agencies that struggle are those that try to replace the lost revenue with a like-for-like replacement, chasing any large account to fill the gap. That approach tends to produce the same structural vulnerability that created the problem in the first place: over-dependence on a small number of large clients, without a sufficiently differentiated commercial proposition.

For the partners and affiliates further down the Stellantis ecosystem, the restructure will likely mean changes to co-marketing arrangements, joint campaign structures, and the terms on which commercial partnerships operate. Those changes create both risk and opportunity, depending on how well the partner relationship was structured in the first place.

What Should You Take Away From This?

The Stellantis situation is a reminder that marketing partnerships are commercial relationships, not just operational ones. They exist to create business value, and when they stop doing that, or when the business can no longer clearly see that they are doing that, they become vulnerable.

That is true whether you are managing a multi-million dollar agency relationship or a relatively modest affiliate program. The question is always the same: is this partnership creating measurable commercial value, and can I demonstrate that clearly when I need to?

Early in my career, I worked on a paid search campaign at lastminute.com for a music festival. It was not a complicated campaign. But within roughly a day of going live, it had generated six figures of revenue. The reason that campaign worked was not because the execution was particularly sophisticated. It was because the commercial objective was clear, the measurement was in place before we started, and everyone involved understood what success looked like. That clarity made it possible to act quickly and to demonstrate value immediately.

Most marketing partnerships fail not because of poor execution but because that clarity was never established. The Stellantis restructure, whatever the specific details, is in the end a story about a business trying to reestablish that clarity under pressure. The lesson for everyone else is to build it in before the pressure arrives.
