GME is ~12B, EBAY is ~46B (58 total) with net income of 0.4B and 2B (2.4 total). If he boosts profit by 1.2B then it's nearly a 50% increase and probably going to result in a more valuable combined company despite the debt.
The most beneficial thing is how even proposing this shifts peoples' perception of Gamestop from a beloved but struggling brick and mortar chain to a successful business
Becoming Radio Shack / Microcenter, as far as 3D Printing and DIY electronics, seems like it intersects with their target audience more, but they're also probably pretty short on space for that.
Maybe from a brick-and-mortor store to yet another private equity fund whose continued existance comes solely from debt and merger trickery.
GameStop had revenues of $3bn last year and eBay was $10-12bn, so combined it's $13-15bn. A net income increase of 1.2bn on that gross is a tall order for M&A efficiencies. Especially difficult when the two companies have essentially zero operational crossover, besides business admin. It doesn't seem likely to me that merging eBay's accounting/legal departments into GME's (and similar efficiency gains) is going to save anything close to a billion across the two entities.
IIRC, Gamestop recently had a "trade-in anything" day, where they accepted a variety of products for store credit. Seems an awful lot like this was some sort of test for accepting products in-store for eBay listings, or something along those lines. They already accept trading cards to send off to PSA for grading and to place into their lootbox system.
As far as efficiencies go, you can see things like shifting shipping by individual sellers to mass shipping to/from a warehouse, a much heavier footprint in collectibles, and perhaps quality control that reduces buyer disputes (this one's a bit iffy).
That said IMO the biggest difference in the two situations you're describing is that EBay is not in the business of buying the items to then sell later, they just facilitate transactions between two parties and some of the logistics (depending on the seller). They're similar as far as dealing with "used goods" but the actual design of the business and risk being taken on is very different.
EBay also not really lacking what you're describing - there are fufillment centers that can be used for EBay listings, there's the EBay "Authenticity Guarantee" program for cards, they already own TCGplayer which does all of this for trading cards way better than GameStop does, etc.
Perhaps somehow these things could be improved by GameStop but I can't imagine it being significantly better than it currently is.
Gatestop is a retail operation that buys and sells goods. It takes on all the liability for fake products, it puts capital on the line to purchase used goods, it is a totally different (and worse) business
Sigh. The synergy argument, once again.
While historically most mergers don't work out particularly well, I'm absolutely sure this time will be different.
Just sample from these with replacement sufficiently many times and you're all set. At the very least, you'll owe people so much money that they'll have a massive interest in helping you.
Synergy (i.e.: cost reduction) looks great in Q3 balance sheet, but in the mean time intrinsic company value has decreased. The long term prospect isn't so great.
