Seer investors get $2.25 cash bid plus CVR

Seer, Inc. received an amended Schedule 13D from a group led by Bradley Radoff and Michael Torok outlining an unsolicited takeover proposal and board contest.

Rhea-AI Filing Summary

Seer, Inc. received an amended Schedule 13D from a group led by Bradley Radoff and Michael Torok outlining an unsolicited takeover proposal and board contest. The group and related entities report beneficial ownership stakes ranging from 0.4% to 4.6% of Seer’s Class A common stock.

On April 13, 2026, the reporting persons submitted a non-binding proposal to acquire 100% of Seer’s equity for $2.25 per share in cash, a stated 33% premium to the most recent closing price, plus a contingent value right giving stockholders 80% of net proceeds from any sale or license of Seer’s business and assets, including PrognomiQ. The proposal assumes at least $215 million of net cash and cash equivalents at closing and is not subject to financing conditions.

The group asked Seer’s board to respond to the proposal by 5:00 p.m. ET on April 22, 2026, after which it would expire. Radoff also nominated Howard H. Berman, Joshua S. Horowitz and Luis E. Rinaldini to Seer’s board for the 2026 annual meeting and the group entered into an amended and restated group agreement covering joint filings, proxy solicitation efforts and trading restrictions while Seer’s tax benefit preservation plan (the “NOL Pill”) remains in effect.

Insights

Activism and M&A analyst

Activist group proposes cash buyout of Seer at a 33% premium plus CVR.

The filing shows an investor group led by Bradley Radoff and Michael Torok holding several percent of Seer, Inc. shares and coordinating through a formal group agreement. They now propose to acquire all outstanding equity for $2.25 per share in cash.

The offer includes a contingent value right granting stockholders 80% of net proceeds from any sale or license of Seer’s business and assets, including PrognomiQ, contingent on future transactions. The proposal assumes at least $215 million of net cash and cash equivalents at closing and is not subject to financing conditions.

The group has also launched a proxy effort, nominating three directors for election at the 2026 annual meeting and agreeing not to trade Seer securities without joint consent while the NOL Pill is in place. Future company communications about the board’s response to the April 22, 2026 deadline will clarify whether discussions advance.

Key Terms

6 terms

contingent value right financial

"plus a contingent value right representing the right for stockholders to receive 80% of the net proceeds"

A contingent value right is a special security that gives its holder the right to receive one or more future payments only if specified events happen, such as a product reaching a sales target or getting regulatory approval. It matters to investors because it offers potential extra payout tied to uncertain outcomes—like a bet that a project will succeed—so it can add upside to a deal while also carrying extra risk and valuation uncertainty.

Schedule 13D regulatory

"If the filing person has previously filed a statement on Schedule 13G to report the acquisition"

A Schedule 13D is a legal document that investors file with regulators when they buy a large enough stake in a company to potentially influence its management or decisions. It provides details about the investor’s intention, ownership stake, and plans, helping other investors understand who is gaining control and what their motives might be.

tax benefit preservation plan financial

"the Issuer's tax benefit preservation plan, dated as of February 26, 2026 (the "NOL Pill")"

A tax benefit preservation plan is a company policy and set of legal steps designed to protect valuable tax attributes—like carryforward losses or credits—from being lost if ownership changes. Think of it as locking up a store’s coupons so a new owner can’t void them; preserving those tax items can lower future tax bills and effectively increase the company’s value, so investors watch these plans as protection of potential after‑tax cash flows.

NOL Pill financial

"for so long as the Issuer's tax benefit preservation plan, dated as of February 26, 2026 (the "NOL Pill"), remains in effect"

group agreement regulatory

"entered into an amended and restated group agreement (the "Amended and Restated Group Agreement")"

proxy financial

"the parties agreed to solicit proxies for the election of certain persons nominated for election to the Board"

A proxy is the authorization a shareholder gives to another person or document to cast votes on their behalf at a company meeting. Think of it like handing someone your voting ticket so they can represent your choices on board elections, executive pay, mergers and other big decisions; it matters because proxies determine who controls the company and which proposals pass, directly affecting share value and investor returns.

They submitted a non-binding proposal to acquire 100% of Seer’s equity for $2.25 per share in cash, a stated 33% premium to the most recent closing price, plus a contingent value right for 80% of net proceeds from future business or asset sales.

How is the contingent value right structured in the Seer takeover proposal?

The proposal includes a contingent value right giving stockholders 80% of net proceeds from any license, sale or other disposition of Seer’s business and assets, including PrognomiQ. This right would provide additional upside if future asset monetizations generate meaningful cash proceeds after closing.

What conditions apply to the Seer acquisition proposal at $2.25 per share?

The offer is non-binding and based on Seer having at least $215 million of net cash and cash equivalents at closing. It is described as not being subject to any financing conditions, meaning the proposing group does not condition it on arranging external funding.

What governance actions are the reporting persons taking at Seer’s 2026 annual meeting?
