Lens deal: Sony wants to acquire Tamron for 1.2 billion dollars

As the Japanese business magazine Diamond Online reports, optics manufacturer Tamron has received a takeover bid from Sony. This initially unofficial information has now been confirmed by Tamron confirms. Sony's non-binding takeover offer is currently being reviewed internally:
"It is true that the company has received a non-binding proposal from Sony Corporation regarding a series of transactions through which the company would become a wholly owned subsidiary of Sony Group Corporation. It is also true that, in response to this proposal, the company has established a special committee to examine various options to increase its corporate value."

For industry insiders, this step is actually not entirely surprising, as the two companies have long had close business ties. For a long time, Sony was Tamron's largest single shareholder with a stake of around 15 percent, while Tamron produces over 20 lenses for Sony's E-mount system. This year, Sony was surpassed in terms of share volume by the hedge fund Effissimo Capital Management, which now holds 17.4 percent of Tamron's shares and has a reputation for actively interfering in corporate affairs, which in turn could threaten Sony's interests.
Sony itself emphasizes that the measure is intended to "increase Tamron's corporate value and contribute to Sony's imaging business." Tamron's stock surged following the news due to massive buy orders, whereas Sony shares dropped by about 1.7 percent. Should the acquisition deal—which, according to Diamond Online, could cost Sony around 1.2 billion USD—be approved, the procedure could still take months or even years due to the necessary antitrust approvals.
What if?
As is well known, Tamron not only builds lenses for Sony cameras, but also for Canon and Nikon, among others; this year, Tamron even announced more new Z-lenses than Nikon itself. How the supply of "third-party mounts" will proceed in the event of a complete takeover by Sony is therefore the big question.
In a status quo scenario, Tamron would continue to supply other mounts as an independent subsidiary, while Sony collects the profits (and retains insight into competing systems). Of course, preferential treatment for the Sony E-mount regarding launches, pricing, or exclusive models is quite conceivable. A complete discontinuation of third-party mount products would mean a loss of revenue and is therefore presumably less likely.
