Cirrus Logic made its own bid for Synaptics, trying to derail the Onsemi deal

Audio chipmaker Cirrus Logic made a surprise offer to buy Synaptics in September, trying to derail the company's already agreed sale to Onsemi. Bloomberg reporters Liana Baker and Yiqin Shen reported this, citing people familiar with the matter. The bidder's identity emerged from an updated document Synaptics submitted on Thursday, which refers to a mysterious "Party A." According to the sources, that party is Cirrus Logic.

What is known about the bid

Bloomberg's report contains few public details, and that matters. The price of Cirrus's offer has not been disclosed. The terms of Synaptics' agreement with Onsemi are also unknown. It is likewise unclear whether Cirrus is still in the running or backed off after Synaptics declined to revisit the agreement.

Here is the picture so far:

• bidder: Cirrus Logic, identified in the filing as "Party A";
• target: Synaptics, with which Onsemi has already agreed a deal;
• timing of the offer: September 2026;
• moment of disclosure: Synaptics' updated filing, submitted on Thursday;
• source: people familiar with the matter, as relayed by Bloomberg;
• current status of Cirrus's bid: unconfirmed.

The disclosure format itself is telling. For agreed deals, target companies must describe how negotiations unfolded, including the participants, who are kept anonymous. Journalists then decode these "Party A, B, C" labels.

Why Synaptics attracted interest

Synaptics is known as a supplier of chips for input devices and interfaces: touch controllers, solutions for displays and laptops, and wireless modules. In recent years the company has also been promoting processors for edge AI, meaning running models directly on the device without calling the cloud. For buyers in adjacent segments, that is an attractive combination: established product lines plus access to the growing edge computing market.

The buyers are interesting in their own right. Onsemi works in power electronics and sensing and is strong in the automotive and industrial segments. Cirrus Logic, by contrast, has historically been tied to audio and mixed-signal chips in smartphones and wearables. For Onsemi, Synaptics would extend the portfolio toward consumer electronics and edge AI. For Cirrus, a deal would mean moving beyond sound into a broader set of interface chips. Two bids with different logic show that the asset is valued differently.

How these stories usually unfold

A competing bid after a deal is signed puts the target company's board in an awkward position. A merger agreement usually restricts the search for alternatives, but it allows the board to consider "superior proposals" if they look serious. Several scenarios are possible from here: Onsemi raises its price, Cirrus makes a formal offer, or both sides stay put and the original deal moves toward closing.

Nothing directly states which path has been chosen. Bloomberg's wording about Cirrus's unclear involvement leaves all options open.

What to watch next

If you follow the chip market, three things are worth tracking. First: new Synaptics documents in its regulatory filings. That is where details of competing offers and changes to terms usually appear. Second: a possible price adjustment from Onsemi, which would signal real competition. Third: any comments from Cirrus Logic about its strategy, especially on expanding beyond audio.

Engineers and procurement teams that use Synaptics products should not expect immediate changes. Deals like this take months to close, and until then the companies operate independently. But when planning long-term supply contracts, keep in mind that the vendor's owner may change.
