Once again, PE inserts itself to attempt to do more harm than good…

First off, who exactly would be the buyer for the full SF company as it sits today? (Well, PE I guess…). They’re already strategically selling properties that they don’t feel fit into their long term strategy—selling the whole chain (AGAIN!) would only dump more debt onto the balance sheet because the company that gets purchased always seems to end up with the debt when PE is involved…

Jeesh, guys—John has only been CEO for like 90 days—give it at least a few quarters to allow his strategy to play out 🙄

These people need to go to United Parks and ask them how private equity is working out for them.....newsflash its NOT!

Hopefully this is the beginning of the end of Six Flags as we know it. I'd rather take a little gamble on who owns Kings Island than see it continue to stagnate.

[Losantiville Mining Co.]

That also means Six Flags could be taken over by private equity, just as happened with Busch>SeaWorld>United Parks. Taking a gamble on who owns and operates Kings Island is much riskier when the big operator playing field is so limited. Six Flags and Cedar Fair merged, Herschend is paying off their purchase of the Palace properties, and United Parks is already in the thralls of private equity. Enchanted Parks is also off of the table since they're already taking on the management of 6 Six Flags parks. Are there any other big North American park chains that I'm not thinking of? 

If this is just going to be an uphill battle then I believe the best way to stave off a potential takeover would be for the company to split itself into 2-3 smaller, more manageable chains. That 2-3 separate chains is also after the sale to Enchanted Parks. Kings Island could be the crown jewel of a new chain if they separated. 

 

As jzarley said, we've barely seen what Six Flags looks like under John Reilly and some of the other new leadership. Only 4 parks have been open for more than a few days in 2026 so far. The first couple of opening weekends have seemed to go poorly, but I think that's pretty standard for these parks.

So... we basically go back to what it was like before the merger happened in the first place? LOL... 

I'm with you though. It's a mess and probably shouldn't have happened... 

Also, I still find it interesting how Cedar Fair didn't learn from the sins and mistakes of Premier Parks during the first Six Flags acquisition process years ago. Newsflash to corporate executives, it's probably not a good idea to take the name of the struggling company you're buying out... Especially when that struggling company's name and brand is synonymous with "lower quality" to the general public...

Yes! I'm not entirely a "This merger was a mistake and should never have happened" guys, but I do think splitting the company up would help in the long run. The fact that they took on the Six Flags name still baffles me. They chose brand recognition for a bad brand over making up a new name and trying to start somewhat fresh. Six Flags also still uses the legacy branding on their social media accounts despite having a new logo and a whole other set of branding conventions that they could use from the Cedar Fair side of the company.

Everyone with a brain knew merging with Six Flags would be a disaster like almost any merger that has happened in history! I literally can't believe coaster enthusiasts and CF employees/stockholders didn't try and at least attempt to organize some sort of revolt/protest to try and stop the merger. (not that it 100% would've worked but we've seen proposed mergers get stopped by protests in the past). Plus it would've gotten insane news coverage if a revolt got organized and happened. Sports fans remember Greg Schiano to Tennessee? That was stopped bc fans (and others higher up) put their foot down and spoke out against it as they knew it wasn't going to work. Also Mark Stoops to Texas A&M or Cracker Barrel and the proposed rebrand.

What were coaster enthusiasts supposed to do? They/we have no sway over anything.

Not sure those are good examples. Last I checked Tennessee and A&M are still underperforming considering their revenue and fanbases. And Cracker Barrel...well, okay they should have known better but the change was completely harmless. I still can't believe I had to hear about that nonstop for a full week as if it was a national tragedy.

[Losantiville Mining Co.]

I think the only ones who could have had a chance at stopping the merger would have been the stockholders. It felt like the higher-ups from both companies wanted the merger to happen. If they hadn't merged I think there's a world where some of the lower-tier legacy Six Flags parks would've been in danger of closing instead of being purchased by a chain or operating independently. Either way, the merger is already done and we're beating a dead horse. (I also think the Cracker Barrel rebrand was always planned to be reversed in some way, but that's neither here nor there.) 

After my last post I watched a Green Tagged video about this letter from JANA Partners and they mentioned a few things that I hadn't remembered hearing. It was said that they want the board to replace Marylin Speigel as Chairman and to reorganize/replace other board members either in an effort to bring in fresh ideas and move away from the old guard or to replace them with board members who align more with JANA's goals. Allegedly the Travis Kelce x Six Flags brand partnership might not have paid off like they wanted so this letter was the next move. It was also mentioned in the letter that they like John Reilly and what he's trying to do for Six Flags. Generally it seemed like they might see certain board members as road blocks to making this vision a reality so I'm inclined to agree with JANA if this is the case. That said, there is a chance that they want to replace board members in a private equity-esque manner. Going back to the use of legacy branding (especially on social media) I'm convinced that this is still used because of some board members trying to hold onto that brand despite it being synonymous with poor quality. 

If I had my way I'd try replacing board members with non-Cedar Fair or Six Flags veterans (but still amusement/theme park company veterans), and see how that goes before thinking more about splitting the company. If that doesn't work then I'd split the company into two independent operators based on location and what I think they'd be best suited for. I've written about my wishes for a new KECO on here before so I'll keep this to just my lists for now. You may not agree with my choices but I think they could work well.

Company 1 (Thrilling Theme Parks): Kings Island, Kings Dominion, Canada's Wonderland, Carowinds, SF New England (renamed Riverside Wonderland), Great Adventure, Fiesta Texas, Knott's Berry Farm, Darien Lake, and Chicago's Great America

Company 2 (Themed Amusement Parks): Cedar Point, Discovery Kingdom, Frontier City, Six Flags Over Texas, Six Flags Over Georgia, Dorney Park, Magic Mountain, SF Mexico, SF Qiddiya City, and the park-independent Hurricane Harbor locations

I like how Jana took stake in October. It’s been 6 months. Over the time the organization isn’t really in business (parks operating), the CEO officially stepped down, and multiple other things have happened since then, so of course things are a bit dysfunctional. I mean I don’t think the ship is going in the right direction, but the captain needs to be able to steer it to put it on the right course.
