The Hidden Tax Strategy Behind the Unilever–McCormick Merger

April 17, 2026 / 10:07

This episode discusses the merger between Unilever's food business and McCormick, focusing on the concept of a Reverse Morris Trust (RMT). Emilie Feldman, a Professor of Management at the Wharton School, explains how RMTs work and their potential benefits.

Feldman defines a Reverse Morris Trust as a corporate transaction that combines a spinoff and a merger. In this case, Unilever is spinning off its food business and merging it with McCormick, which allows for a tax-efficient structure and strategic fit.

The discussion highlights the tax advantages of RMTs, where the spun-off entity must be the majority owner of the merged company. This structure imposes discipline on the choice of merger partners and ensures that both companies align strategically.

Feldman also notes that RMTs are rare, with only 50 occurring since 1998, and emphasizes the importance of economies of scale and cost savings in these transactions. She hopes that the Unilever-McCormick merger will bring more attention to RMTs in the M&A landscape.

The episode concludes with a reflection on the broader implications of this merger for the food industry and the potential for future RMTs.

00:00:00
The recent announcement that Unilever's food business was going to combine with
00:00:04
McCormick's sent investors selling off both stocks. Traditionally, mergers in the food industry may look good on paper, but not always
00:00:16
play out well when you're looking at the final numbers. However, this one may very well work out.
00:00:22
And it's an interesting reason why. To explain it, we're joined by Emilie Feldman, who's
00:00:27
Professor of Management here at the Wharton School. Emilie, great to talk to you again.
00:00:32
And I guess let's start out by looking at why you think this may work out. And it's this concept of an RMT.
00:00:40
Can you explain it? Yeah, thanks Dan. I'm happy to. So maybe a definition would be helpful, because these are fairly rare.
00:00:48
So, what is a reverse Morris Trust? These are corporate transactions that combine a
00:00:53
spinoff and a merger within the same transaction. So you have a parent company that spins off one of its business units and
00:01:01
immediately merges that unit with some other entity. So in this case, we have Unilever spinning off its food
00:01:08
business and immediately merging that with McCormick. So that's the RMT structure.
00:01:12
And there's a whole bunch of tax stuff that's important. And we can talk about some of that if you like.
00:01:18
But what's unique about these transactions is basically the discipline that the
00:01:24
structure imposes on the companies that are involved. Because on the spinoff side, what we have is really a company that is parting ways
00:01:33
with a unit that might not be a great fit within its portfolio. So thinking about getting rid of something that doesn't necessarily make sense.
00:01:41
But then the ability to combine that via a merger with some other company is really the unique feature of this.
00:01:49
Because normally in a spinoff, we would not see the benefit of synergies, for example.
00:01:54
And there are various tax rules, like I mentioned, that tie into this. But the fact that companies have to be very careful to meet these rules and abide
00:02:05
by them can impart some discipline into which partners are chosen and how the ownership split is divided basically between the unit that's
00:02:14
being spun off and the company that it's merging with. Okay, so you talk about the tax component of this.
00:02:18
What specifically is it within the rules that when you're doing an RMT actually
00:02:24
ends up being a benefit from a tax perspective? Yeah, definitely. So what happens is that in general, corporate spinoffs can be tax-free transactions.
00:02:34
And there are a set of rules that companies have to abide by for that to be the case.
00:02:39
One of those rules is that no entity can acquire the unit that's being spun off
00:02:46
within two years after the completion of the transaction. And if you think about it, you can see why.
00:02:50
Because basically, you'd be kind of engineering a tax-free sale at that point.
00:02:55
Because if the spinoff is tax-free, but you're not taxing, someone is immediately acquiring it. Then you basically engineered a tax-free sale.
00:03:02
So what is clever about an RMT is that nobody's acquiring the entity that's being spun off.
00:03:09
The entity that's being spun off is actually— has to be, from a tax perspective, the majority owner in the merged company.
00:03:16
So in other words, nobody bought the spunoff unit, but it bought something else, right?
00:03:20
And so as a result, that's really the tax rule that is kind of the key feature of this.
00:03:25
And so you end up with that merged company that has the spunoff entity owning more than 50% of that combined entity.
00:03:33
And the company that it merged with, or acquired, owning less than 50% of that entity.
00:03:39
And so my thought on this, right, is that this really imparts a lot of discipline, right, into the choice of merger partner, because
00:03:47
it has to be the right size, it has to be the right fit. You can't have some unwieldy structure, right, where
00:03:53
that ownership split is not going to be met exactly. And there has to be a willingness on the part
00:03:58
of the target company to participate as well. So it's two sides. So when you're talking about a company like Unilever, who obviously has so many
00:04:05
different products, and they're looking to basically move on from their food
00:04:09
business, and they match it up with a food company. This would seemingly be one of those instances when you're
00:04:16
just looking at the entities involved, that it would work. But that isn't always the case, correct?
00:04:23
Correct. Yeah. And I think— so what kind of struck me about this is that no one— no one thinks about it this way.
00:04:28
But what is mayonnaise, right? Mayonnaise is a spice, right? It's a flavor. And what is McCormick's identity?
00:04:35
It's flavor, right? So I think that that idea of kind of fit, that idea of strategic logic, right?
00:04:41
We're not merging with some company that has a whole bunch of different operations in this other area.
00:04:47
And we'll figure out what to do with it later, right? There's a really kind of close and tailored attention to
00:04:53
kind of getting the right partner in this type of situation. And I think this McCormick transaction really exemplifies that perfectly.
00:05:00
Do you tend to see, then, RMTs occur more so in certain industries or within companies
00:05:06
within certain industries rather than others? Yeah, so let me contextualize it then.
00:05:11
And then I'll answer your question. So first of all, as you might imagine, given the conversation
00:05:15
that we've had so far, RMTs are exceedingly rare. Yeah. So in the study that I'm working on, which covers the period 1998 to 2023—
00:05:25
these transactions started being used in 1998, by the way. There have been 50, right?
00:05:30
49 of them from that period, right? So that's very, very small if you think about
00:05:34
the volume of M&A activity over that time period. So in general, these are rare.
00:05:40
Now to answer your question, yes, there is industry concentration, right? And so this is what's kind of unique about these deals, that we see them in contexts
00:05:49
where synergies, especially from scale, are going to be valuable, right? So we see this a lot in IT services.
00:05:57
We see this a lot in telecom and media. We see it a lot in radio stations, right?
00:06:01
We see it a lot in oil and gas assets. And we see it a lot in fast-moving consumer goods, CPG types of contexts as well.
00:06:11
Because precisely these ideas of kind of creating synergies, driving the cost structure down, and really getting those benefits of scale are the key advantage.
00:06:20
So then with these having been so rare over the last, I guess, 25 years or so that you have done this research, and how they seemingly work well,
00:06:30
is there a possibility, is there an avenue that we see other companies looking to
00:06:36
make mergers look at this avenue as a potential way to make a deal work? I hope so, right?
00:06:43
I mean, I think that's, if anything, right, I hope this transaction kind of shines a light on a phenomenon, on a deal type that is maybe not
00:06:51
particularly well understood or even known by people, right? And so I do hope that that's the case.
00:06:58
That being said, right, I think that there's a very real challenge here, as I was sort of mentioning, of executing these deals properly, right?
00:07:06
So you have to have that ownership split between the spun off business and the target company.
00:07:12
The merger partner has to be willing to participate. And that's not always the case, right?
00:07:17
If you think about it, you're basically going from being an independent, publicly-traded company as the target, to them being a minority player in that
00:07:25
combined entity. That might not be appealing to every company, every public company that's out there, especially so because the acquire,
00:07:33
so to speak, is just a division within some other companies. So there might even be an ego thing going on there
00:07:38
in terms of some of that— some of that dynamic. So I think that those structural challenges are very real, right?
00:07:45
Those execution challenges are very real in terms of getting those right merger partners to play.
00:07:50
And so even though I hope it happens, right, I think— I think that reality needs to be acknowledged.
00:07:55
So then what kind of impact then is it, possibly, that this type of a merger has on
00:08:02
the larger M&A landscape as we move forward here? Yeah, that's a good question.
00:08:07
And I think that here, the strategy piece becomes very important to emphasize, right?
00:08:12
And so, what are Unilever and McCormick trying to accomplish from a strategic perspective, right?
00:08:17
This is, for me at least, all about economies of scale and cost savings, right? Because basically we have McCormick with huge distribution channels, you know,
00:08:27
great assets, and the more "flavor" types of products that we can kind of pump into
00:08:32
that, the more we can drive that cost structure down, right? And so a bigger company, more scale, kind of driving those products out to
00:08:41
consumers and shaping that cost structure is the key advantage. And so what my research on this topic shows, we have kind of a neat framework in
00:08:50
this paper that disaggregates the benefits from scale versus scope, right? So scale being more of the same, scope being a greater diversity of products,
00:08:59
and then revenue enhancement versus cost reduction. And so what we find actually is that among the RMTs, the ones that are geared
00:09:07
specifically towards cost reductions from economies of scale tend to exhibit the greatest shareholder returns, right?
00:09:15
The highest shareholder returns. And so, you know, even if we don't see a proliferation of RMTs, my hope is that
00:09:21
this research sort of underscores the importance of the value driver of cost synergies and economies of scale as the factor that actually tends to create more
00:09:31
value for companies that are engaging in M&A. And that's not specific to RMTs.
00:09:35
That's general to mergers and acquisitions. Emilie, thanks for explaining it.
00:09:39
Very interesting, to go over this. And for those of us that like mayonnaise every once in a while, it gives us a whole
00:09:46
new landscape to think about where our mayonnaise is coming from. Thanks, Dan. - Thank you.
