Updates: STEF SA & Gerard Perrier SA

DISCLAIMER: This is not investment advice. PLEASE DO YOUR OWN RESEARCH !!!

Summary

In this update post, I look at two of my French stock positions, STEF SA and Gerard Perrier. For STEF, I reduced my position by 1% of the portfolio because of problems with the integration of newly acquired companies. In contrast, I increased my Gerard Perrier position by 1,5% of the Portfolio as business is accelerating and they seem to have made some very good acquisitions in the Defense/Aerospace and Digital space.

STEF SA

Stef is a company that I analyzed and wrote about 2 years ago. In essence, I considered it a cheap but reliable infrastructure-like cold-storage company with a great track record that is consolidating several European markets. For such a “compounder”, the price looked very cheap at around 8xP/E.

However, things turned out a little differently than I thought. While 2024 was a little bit weaker than 2024, 2025 saw a significant decline in EPS to a level of less than 50% of the 2023 earnings.

According to the 2025 investor presentation, this was a combination of one-time effects (Tax France, VAT Italy) and slower than expected integration success in its recent acquisitions.

To my own discredit, I failed to follow up on the 6M sales release from STEF which still looked good. I should have looked at the full half year report instead.

This is how the explain the declin:

Also, net debt increased by 200 mn.

The dividend was cut to 2,70 EUR from 4,15 EUR the year before (and 5,10 EUR in 2023). This is understandable from a company perspective but somewhat unfortunate for investors.

Analyst estimates seem to expect a recovery in 2026 and the following years according to TIKR:

Share price wise, the stock is almost exactly where it was when I wrote up STEF. Interestingly the US peers did much worse:

A quick look into Americold’s 2025 press release shows decliningorganic sales and mention of “speculative developments” in the cold storage industry.

Also Lineage reported declining sales in 2025.

Both US peers are extremely highly leveraged (8x EV/EBITDA) and therefore very vulnerable to negative economic developments. However, also STEF’s net debt to EBITDA ratio increased from 2,5x in 2023 to 3,5x in 2025. Still manageable but if interest rates increase, this will represent another headwind for them.

My conclusion at this stage is that Stef clearly has over-extended itself with its acquisitions in the neighbouring countries and has not been able to integrate them successfully so far.

Management mentions that things should “normalize” in 2026 and Q1 revenue looked ok, but experience shows that the full integration of the newly acquired company can take much more time.

Although I am not ready to throw in the towel yet, I do think that my initial 5% allocation (currently 4,5%)  was too high and reduced the position by 1% of the portfolio to ~3,5%.

The positive aspect of this story is clearly that I bought cheap enough which protected me against a significant loss of invested capital.

Gerard Perrier

On the surface, Gerard Perrier is a little bit similar to Stef insofar as 2025 was a year when earnings went down slightly:

Despite still growing sales, EPS was -8% lower than in 2024. 2024 again was more or less unchanged from 2023.

In Gerard Perrier’s case however, the explanation is not that they didn’t integrate new acquisition but a temporal weakness in their Energy segment which comprises mostly the servicing of the French nuclear fleet.

This is the translation (from Gemini) from G. Perriers report:

“The activity of the Energy division (ARDATEM, TECHNISONIC), which includes services for the nuclear sector, saw its production decrease by 8.2%, falling from €89.8 million to €82.4 million. This slowdown is mainly explained by the transitional effect of the reduction in reactor outages and maintenance activities at power plants this year, as well as by a rationalization policy of nuclear operations in France, although the sector remains on a positive dynamic in the medium term.” 

In addition, even without much growth in the Energy segment so far, G. Perrier had a great start into 2026 with sales up by +10% yoy:

As we can see, especially the “Installation Maintenance” and the Aerospace/Defense segments are doing well.

What I found interesting is that there was almost no reaction to this news in the share price:

What I do like is that their recent acquisitions look very interesting. With N-Cyp they acquired a small specialist company for industrial cyber defense, with OFATEC they get access to the Data Center market and with the acquisition of the three companies AQLE, SOMALEC et SOMALEC SUPPLY they strengthened their defense/aerospace segment, including components for the Ariane Space missile program.

Another data point that I found interesting is that G. Perrier has still around 230 open positions as per their web site:

Most of the jobs are open at Ardatem (137), the Nuclear service company, which seems to imply that they expect a lot more work going forward.
Overall, I do think that Gerard Perrier offers a very attractive return/risk profile especially on the basis of the currently accelerating business numbers, therefore I increased my position from a previous 3,5% weight to 5% of the portfolio. The additional 1,5% were bought at an average price of around 83 EUR per share.

Notes & impressions from Omaha 2026

This year, after a 7 year break, I once again went to the US to attend the Berkshire AGM. Just for clarification: I don’t own Berkshire shares and unfortunately never did because I always thought that they were too expensive.

Attendance:
As mentioned elsewhere, attendance was clearly lower than in the past. The arena was only half full, the overflow rooms almost empty. On the positive side, with less people it was much more relaxed. On the negative side, prices in Omaha during the weekend are still sky high. Hotel rooms have been very expensive and Steaks in the city steakhouses cost around 60-70 USD (plus sides, taxes and obligatory tip). Most restaurants were only half full. It also seems that hotel prices for the weekend were much lower just before the weekend.

Paying 21 USD for a pretty miserable “Lunch box” during the AGM was not big fun either.

I wonder if Omaha hotels and restaurants will still be able to charge those sky high prices next year.

AGM Content:

Greg Abel is clearly not Warren Buffett. He is much more a “normal”, more operative CEO than Buffett. He also  gave more air time to the other Berkshire business CEOs.

What I liked is that they clearly said that BNSF and Geico still have a lot of work to do, in order to become as good as their competitors. Another plus was that the Q&A session was not too long.

On the other side, Greg Abel clearly did not offer any philosophical insights on capital markets. This was different when Warren and Charlie were running the show and attracted the masses.  And I think it is a good thing that he didn’t even try to do it.

Buffett himself appeared twice, once in a video and then in a half time break interview with Betty Quick. This interview was actually a little bit “cringe” especially when he mentioned that Greg Abel, a Canadian would become American soon and how special an American Passport is. As a Canadian Berkshire investor, I would be pretty pissed off by those comments as it kind of implies that being a Canadian is not good enough to run Berkshire. In any case, I found it super hard to actually understand what Buffett was saying during the interview. 

From an “actionable idea” point of view, the only inspiration I took away from the AGM is the  Tokio Marine Insurance investment. This was clearly Ajit’s idea and despite showing his age, this guy knows what he is doing in insurance. It was also interesting that this was mentioned very prominently despite being a rather small position for Berkshire.

Overall it will be interesting to see how this will develop over the next few years. Will Omoha still remain a meeting point for investors from around the world or will there be another kind of Omaha elsewhere ? We’ll find out eventually.

Berkshire Stock

For Berkshire, I do think the biggest risk is that the company will be seen as a “normal” HoldCo or a normal Insurance company. Normal Holdco’s often trade at steep discounts to their “sum-of-the-part” value. Berkshire so far could always count on the “Buffett factor”, but it will be interesting if and for how long this lasts, especially as it is not easy to really understand who owns what (Insurance, Non-insurance) at Berkshire.

Another aspect is that Berkshire in the past was also seen as a good proxy for the overall US economy due to its significant diversification. These days, this is no longer the case as the portfolio lacks exposure mainly to Big Tech/Cloud/KI and Defense which have been the strongest performers over the previous years.

Maybe that will be an advantage going forward but Berkshire is clearly not a good proxy for the overall US economy anymore.

As I mentioned, I was never a shareholder, but at the moment I would be really cautious with the stock. The market seems to think in similar ways:

The most interesting question is clearly, what Greg Abel will do with the cash pile at Berkshire. The AGM provided very little insight into this unfortunately. 

General observations:

As in the past, for me the reason to go there is mostly the network of investors and the pre-AGM events. I was again able to attend a two day meeting of German Speaking investors in Omaha and before that did some company visits in Dallas with a group of German “investor friends”. As in the past, the actual Berkshire AGM was always only the cherry on the top.

I actually contemplated for some time if I should go to the US at all because of all the political noise and scary stories about the immigration. However, in my case, immigration was super easy and even kind of friendly (Dallas airport).

As in the past, in all private encounters, Americans are always super friendly. We were often asked by random people in the Supermarket or elsewhere where we come from and when we said “Germany” everyone was super friendly and mentioned relatives or previous visits. So on a personal level, at least the Americans that I met, were as friendly as they always were.

However, in most business settings it was clear that Americans are obviously avoiding to say anything negative about the current US Administration. We never pressed the topic but it is really interesting that no one seems to be willing to say anything critical at all.

In Dallas, one could see quite a lot of Waymos driving around plus some of the autonomous Ubers.

Price levels in general are clearly higher than in Europe. Restaurants, apart from basic Fast food places, are at least 50% more expensive than even in my very expensive hometown Munich, especially if you include taxes and the more or less obligatory 20% tip. It is also interesting how aggressively tipping is demanded even for basic non-service offerings like in airports or coffee shops. Unfortunately this is now much more common in Germany, too.

Another cost factor is that there is very little in the form of public transportation. You either need a rental car or pay for an Uber. Over can be sometimes quite expensive. In Denver, where I had a forced overnight stop-over, I paid almost 60 USD for a 15 minute ride, with Uber charging almost 50% of the total fee at 11 pm.

A final observation is that flying domestically in the US is also a pretty miserable experience. If you don’t pay extra, you will need to wait longer at Security and will board last. Boarding is always a “high stress” event as many Americans travel with the maximum allowed onboard luggage, so compartments fill up very quickly.

My personal highlight was the visit to a real Rodeo outside of Omaha. I have never been to such an event but it was great fun and even good “value for money”.

Will I go there again ?

Currently I am not sure. Overall, it is quite an expensive trip and the main attraction is to meet people that in theory, I could meet much easier in Europe than in far away Omaha. In addition, I had a pretty exhausting trip back.

From a pure financial perspective, going to Omaha is clearly not “great value”. However, on a personal level it was clearly a net positive. experience.

DCC – Interesting “Special Situation” following KKR potential buyout offer at 58 GBP ?

Disclaimer: This is not investment advice. PLEASE DO YOUR OWN RESEARCH !!!!!

DCC is an investment I made back in December 2022. The investment thesis back then was that it was a successful compounder/serial acquirer that had the opportunity to grow further through its 3 platforms (Energy, Healthcare, Technology).

In the meantime, a lot of unexpected things happened. After issues in the non-Energy segments, DCC is currently transforming itself back into the original Energy distributor and sold already a significant part of its non.Energy businesses. The transformation has progressed well including a share buy back tender but is not finished yet.

Looking at the share price, we can see that not much happened over the last 5 years but that the timing for buying into DCC in Dec 2022 retrospect was quite lucky:

After the recent jump to 58 GBP, I am up 42% in total (in EUR, including dividends) which is not spectacular and rather at the lower end of my expected outcome. However, given the “Pivot” it is still a decent result and mostly attributable to the low entry point and the relevant dividends.

Now fast forward to last week: 

Private Equity behemoth KKR and another energy focused PE called Energy Capital Partners approached DCC and seem to have informally offered to take over DCC at 58 GPB per share which only represents a 15% premium over the average share price for the last few months.

DCC immediately declined the offer as “too low”.

Energy Capital Partners is a pretty large Energy focused US PE/Infrastructure investor that owns a lot of “Energy Transition” businesses. AuM seems to be north of 40 bn USD.

Although KKR did not disclose which fund is bidding, it looks that both KKR and ECP see this as an infrastructure play which makes a lot of sense.

58 GBP per share is clearly a low ball offer and no formal offer has yet been made. Under the applicable Irish laws, KKR has time until June 10th to either submit a formal offer or walk away.

From a shareholder perspective, I assume that maybe a lot of investors have been frustrated that the stock only went sideways for the last 5 years or so and are maybe happy to exit at that level.

The “asset heavy” Infrastructure PE playbook

DCC so far has operated as a relatively capital light distributor, but I think it is relatively easy to pivot them into an Infrastructure like business that usually enjoys significantly lower cost of capital.

In contrast to “normal” Private Equity, Infrastructure Private Equity still enjoys a pretty good time. Many players have raised large funds and are eager to deploy money. Infrastructure is often considered “AI safe” these days.

So I guess there might be a chance that some other players might look very closely at this situation. DCC is a very obvious target and the timing is quite nice from a PE perspective. The refocusising on Energy at DCC is still underway and the results don’t look so “clean” at the moment,

DCCs business model, especially the LPG distribution business has a lot of potential to get easy access to many SME companies and sell them solutions.

Especially the current volatility in fossil energy prices opens up a unique selling opportunity for solutions that offer less exposure like rooftop solar etc. 

According to TIKR, DCC’s Net debt to EBITDA ratio is only around 1,2x. The company is valued at around 7xEV/EBITDA. The typical infrastructure playbook would be to make the company more “asset heavy”. Due to the low gearing, this could be financed by more leverage. A typical “asset owning” infrastructure company with longer term contracts can be easily levered 4-5x Net debt/EBITDA, 

In DCC’s case, with around 900 mn in EBITDA, increasing the leverage ratio to 4x would allow them to issue almost 3 bn in debt which could finance a lot of assets. Those assets then will automatically increase EBITDA,

A stabilized infrastructure like company can then be sold at much higher multiples, usually at 12-15x EV/EBITDA. So the value creation potential for a good Infrastructure PE shop is significant. 

Just for fun I did a high level calculation how that exercise would look from this perspective (I just took the current numbers from TIKR, before further disposals):

A potential IRR of above 20% p.a. is highly attractive for an Infrastructure fund and as I have written before, PE’s have some more levers to “juice up” the IRR and earn even higher performance fees.

Is DCC now an interesting special situation play ?

There is clearly the risk that DCC might reject even higher offers, but I do think the 58 GBP low ball offer provides a decent “floor” for the stock (“Anchoring effect”).

For one, DCC should expect some positive operational tailwinds. Volatile and high energy prices in the past have been good for DCC’s energy business. As we can see every day “at the pump”, distributors like normal Petrol stations immediately increase prices although they often have inventories for some weeks/months and often drop prices much slower.

Looking back to the last energy price shock in 2022, we can see that this was DCC’s best year, especially for the energy business:

Although there is no guarantee that the same will apply to 2026, there is a high likelihood that 2026 will look good for DCC from an operational perspective.

In addition, I do expect that the transformation will be more or less completed in the 2026 calendar year. 

So all in all, 2026 seems to look pretty good for DCC. I think this also explains the timing of KKR and ECP, as they don’t want to wait until this improvement shows in the results of DCC.

Even in case, DCC gets sold relatively quickly at 58 GBP per share, one would still get the Dividend that will be recorded end of may.

Quick handicapping exercise:

Overall, I would see the probabilities as follows until the end of the year::

25% probability of no deal with 55 GBP as the outcome (plus dividend, currently estimated at 2,10 GBP/share)

15% of a deal at 58 GBP (plus dividend)

60% probability of a better deal. My guess here would be 70 GBP plus Dividend

This is the quick and dirty calculation:

So based on my assumptions, my probability weighted expected return is around 16% until year end. This looks attractive to me, as in my opinion, the downside is very limited.

Of course, all the assumptions can be challenged and changed.

Summary:

So in total I see the following situation here:

  • The bid of 58 GBP is clearly too low
  • DCC’s short term operational results are supported by increasing energy prices
  • in addition, the full effect of the transformation “back to energy” will materialize in the following quarter
  • Other Infrastructure funds might also be interested in DCC

So even if the bid from KKR would not be successful, I do think that the share price has much more upside than downside potential at the moment.

From that perspective, I decided not to sell any DCC shares but rather increase my position by ~1,5 % of total portfolio value at around 57,50 GBP per share.

Bachem AG: Riding the “Golden Age of Peptides” with this Hidden Champion from Switzerland

Disclaimer: This is not investment advice. PLEASE DO YOUR OWN RESEARCH !!!

  1. Elevator pitch:

Bachem is a 5 bn CHF market cap Swiss listed pharmaceutical/specialty chemical company which is the global market leader in the (outsourcing of) manufacturing of Polypeptide, a complex molecule and Active Pharmaceutical Ingredient (API) that is, among others, behind the blockbuster drugs Wegovy, Ozempic etc. Demand for those molecules is poised to grow exponentially over the coming 5-7 years (15% market growth p.a. ,“Golden age of Peptides”). 

This growth is driven by several different fundamental growth drivers which increases the certainty of the projected growth rates. The complexity of the production process in addition to regulatory requirements and “Anti China” legislation in the US provides a decent “moat” for the coming years which makes Bachem, despite its relatively high valuation (28×2026 P/E), a very interesting investment case on a 3-5 year time horizon in my opinion.

It is clearly not an investment for everyone, but for more growth oriented investors, Bachem could be an interesting stock to look at. In my case, it is a 3% position for my small “quality growth bucket” alongside Wise and Chapters Group.

  1. Some editorial remarks:

Initially, I planned to write up and invest into both Bachem and its Swiss listed competitor Polypeptide Group. Due to vacation time and the rumour of a PE take-over, Polypeptide share price increased by +50% since I started to deep dive into those two companies which made the stock less attractive. Bachem only went up like +15% so  I therefore concentrate on Bachem.

In addition, I just wanted to make it clear that I write “by hand” but I do use several AI tools during my research (NotebookLM, Claude Cowork). You will find some output of AI models here in this write-up, as for some cases (i.e. making pictures), AI has just much better capabilities than I have.

In any case, I do expect a lot of critical comments on this.

  1. Soundtrack:

In order for my readers to actually listen to the obligatory soundtrack during reading the write-up, I’ll post it right at this spot. I think “Golden Years” from David Bowie is the perfect Soundtrack for this

Deja vu all over again: Allbirds vs. Zapata’s 1998 “fish oil to Dot.com” Pivot

For the older investors among my readers, the name Zapata maybe rings a bell.

In 1998, US fish oil producer Zapata announced that they had enough of fish oil and planned to go big time into the “Internet business”. The history of Zapata itself reads like a novel, among other it was owned in its various incarnations (Real oil company, fish oil nutrition etc.) by George Bush Sen., The Glazer family, Wilbur Ross and Phil Falcone.

As one could imagine, the Dot.com Pivot was not very successful. The final “pivot” then was to transform into the company that is now called Spectrum Brands, a medium successful collection of consumer products. The long term Chart of Spectrum from Google also shows the short & crazy spike from the Dot.com Pivot.

This sounds very similar to Allbird’s recent move to transform from a failing Sneaker company into a super sexy Ai GPUaaS company.

History doesn’t repeat itself but as the saying goes, it rhymes.

If I want to draw some learnings from the Zapata episode, I would point out two things:

  1. The Allbirds Pivot will most likely not lead to long term shareholder value creation
  2. In Zapata’s case, the peak of the bubble was still ~2 years away (April 2018 vs. March 2020). I would not take this as a benchmark but the experience shows that bubbles like Dot.com and potentially also the AI bubble part can run much longer as anyone imagines. Trying to time a bubble based on episodes like this is very difficult.

In any case, the Zapata example shows that rarely anything is new in investing and a pivot of a non-sccessful company into the “hot thing of the moment” company is an old strategy. I guess we will see a lot more of this in the coming weeks / months as the Allbird example has made the backers of this pivot some serieous money.
