Insights

CEO’s Hologic equity is cashed out and cancelled as part of a completed merger.

The transactions show Chairman, President and CEO Stephen P. MacMillan disposing of option awards, restricted stock units, performance stock units and common shares as Hologic is taken private via a merger. Each common share converts into $76.00 in cash plus a contingent value right for up to $3.00.

The filing explains that equity awards are converted into cash-settled rights mirroring this merger consideration, consistent with typical change-of-control treatment. It also notes that, after the effective time, MacMillan no longer beneficially owns any Hologic common stock, including shares previously held through the MacMillan Family Trust.

contingent value right financial
"one (1) contingent value right, which represents the right to receive up to $3.00 in cash"
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.
Merger Consideration financial
"the consideration contemplated by clauses (x) and (y), together, the "Merger Consideration""
Merger consideration is the total payment a company or buyer offers to shareholders of a target company in exchange for combining the two businesses, and can include cash, shares in the surviving company, debt assumption, or a mix of these. Investors care because the form and amount affect the deal’s value, tax consequences, immediate cash received versus future ownership, and the risk and upside of holding new shares — similar to choosing between cash now or stock that could grow later.
Agreement and Plan of Merger regulatory
"Pursuant to the Agreement and Plan of Merger, dated as of October 21, 2025"
An Agreement and Plan of Merger is a formal document where two companies agree to combine into one, outlining how the process will happen. It’s like a step-by-step plan for merging, and it matters because it shows both sides have agreed on the details before the official transition takes place.
Performance Stock Units financial
"Represents the certification of performance results applicable to outstanding Hologic performance stock units ("PSUs")"
Performance stock units are a type of company award that grants employees shares of stock only if certain performance goals are met. They motivate employees to work toward specific company achievements, aligning their interests with those of shareholders. For investors, they can influence a company's future stock supply and reflect management’s confidence in reaching key targets.

FAQ

What does the HOLX Form 4 show about Stephen MacMillan’s Hologic shares?

The Form 4 shows Stephen MacMillan’s Hologic equity being cancelled and converted in a merger. His common stock, options and equity awards were turned into rights to receive cash and contingent value rights, leaving him with no remaining beneficial ownership of Hologic common shares.

What merger consideration do HOLX shareholders receive per share?

Each Hologic common share is converted into the right to receive $76.00 in cash plus one contingent value right for up to an additional $3.00 in cash. This combination of immediate cash and potential future CVR payments is defined as the merger consideration.

How were Stephen MacMillan’s Hologic restricted stock units treated in the merger?

Time-vesting restricted stock units granted before October 21, 2025 convert into the merger consideration per underlying share. Units granted after that date convert into unvested cash-based awards tied to the $76.00 cash amount and any payments on one contingent value right, under their existing vesting terms.

What happened to Stephen MacMillan’s Hologic performance stock units (PSUs)?

The compensation committee certified PSU performance, with goals deemed achieved at target or actual levels. Each outstanding PSU was then cancelled and converted into the right to receive the merger consideration for each underlying share, replacing stock delivery with cash and contingent value right payments.

Does Stephen MacMillan still own any Hologic (HOLX) common stock after the merger?

According to the filing, he no longer beneficially owns any Hologic common stock. All directly and indirectly held shares, including those in the MacMillan Family Trust, were converted into the merger consideration, eliminating his direct and indirect equity ownership in Hologic.

How were deferred Hologic RSUs and PSUs handled for Stephen MacMillan?

A footnote states that 1,079,673 restricted stock units and performance stock units had settlement deferred under Hologic’s Deferred Equity Plan. These units represent contingent rights to shares, which were converted into cash-settled rights to the merger consideration under the same treatment applied to comparable awards.
