A Pac-Man defense is a takeover response in which the target launches or threatens an acquisition bid for the original bidder.
A Pac-Man defense is a takeover response in which the target company launches or credibly threatens an acquisition bid for the original bidder. Instead of only resisting the hostile offer, the target tries to reverse the control contest and force the bidder to defend itself.
The tactic is rare because the target needs financing, legal authority, regulatory capacity, and a credible investment case for buying the bidder. A public counterbid without those foundations may increase disruption without creating negotiating leverage.
The bidder may make an Unsolicited Bid, commence a tender offer, solicit proxies, or accumulate shares. The target board first evaluates price, conditions, financing, regulatory risk, and strategic alternatives.
The target and its advisers assess the bidder’s businesses, ownership, debt, vulnerabilities, regulatory exposure, and shareholder base. They need an acquisition thesis that remains coherent if the original offer disappears.
Funding may include cash, debt commitments, newly issued equity, asset-sale proceeds, partners, or a combination. The target must consider its own covenants, ratings, liquidity, dilution, and ability to refinance the bidder’s obligations.
A credible response normally identifies price, consideration, conditions, financing, approvals, and timing. Buying a small block of bidder shares may signal intent but is not equivalent to a full counteroffer.
Each company may seek shareholder support, amend terms, litigate, pursue defenses, or attract another buyer. The contest can become expensive and operationally distracting before either offer reaches a vote or settlement.
Assume Bidder B has:
Target T has:
Bidder B offers $6.0 billion for Target T. Target T responds with a $9.2 billion proposal for Bidder B.
($6.0 billion - $5.0 billion) / $5.0 billion = 20%
($9.2 billion - $8.0 billion) / $8.0 billion = 15%
Assume Target T proposes to fund the counteroffer with $1.2 billion of cash, $4.0 billion of new debt, and $4.0 billion of new shares.
Before transaction costs, refinancing, or cash adjustments, the combined company would have approximately:
$1.0 billion existing target debt + $2.0 billion bidder debt + $4.0 billion new debt = $7.0 billion debt
Combined EBITDA before synergies would be:
$1.1 billion + $1.4 billion = $2.5 billion
Simplified gross leverage would therefore be:
$7.0 billion / $2.5 billion = 2.8x
That ratio alone does not prove feasibility. The analysis still needs cash balances, debt-like items, transaction fees, refinancing terms, pension obligations, synergies, working capital, taxes, ratings effects, and integration costs.
The board should also ask why Target T can create more value by paying a 15% premium for Bidder B than by accepting, rejecting, or negotiating the 20% premium offered for itself. Defensive purpose is not a substitute for acquisition economics.
The target should identify cash, lender commitments, equity funding, maximum leverage, covenant capacity, and refinancing needs. Financing conditions that give the target broad discretion weaken the threat.
The combination should have a plausible operating and financial case beyond defeating the first offer. Cost synergies, market access, asset fit, governance, and integration requirements need evidence.
The target must specify whether it proposes a merger, tender offer, share exchange, consortium, or another structure. Each path changes approvals, disclosure, timing, and funding.
The response may require directors and shareholders to support substantial leverage, dilution, asset sales, or a shift in strategy. Bidder shareholders may also resist becoming targets.
Antitrust, foreign-investment, industry, securities, and other approvals can affect both competing offers. A reciprocal combination may create different overlaps from the original proposal.

|---|---|---|
| Pac-Man defense | Bids for the original bidder | Financing and independent acquisition rationale |
| Poison Pill | Threatens dilution after an ownership trigger | Board authority, proportionality, and governance |
| Crown Jewels | Transfers or burdens valuable assets | Residual-company value and transaction fairness |
| White Knight | Supports an alternative acquirer | Price, deal protections, and closing certainty |
| Self-tender | Repurchases target securities | Cash, debt, proration, and capital structure |
| Standalone defense | Rejects the bid and presents an independent plan | Forecast credibility and execution risk |
