Learn how to estimate blended value when an issuer tender offer may be prorated, including accepted shares, residual shares, sensitivities, and limitations.
Blended value in an issuer tender offer is a scenario estimate of the average gross value per share tendered when some shares may be purchased at the offer price and the rest remain invested at an estimated post-offer price. It is an analytical shortcut, not a standardized accounting measure, guaranteed return, or valuation of the whole company.
For a holder who tenders all eligible shares, a simplified gross blended value is:
where:
The estimate assumes the same residual value for every unaccepted share. It should be expanded when there are multiple tender prices, a Dutch auction, odd-lot preference, contingent consideration, foreign exchange, or different tax lots.
A company offers to buy 5 million shares at $50 each. Shareholders validly tender 8 million shares. Ignoring odd-lot priority and other adjustments, the simplified expected acceptance rate is:
An investor tenders 1,000 shares and estimates that unaccepted shares will be worth $44 after completion. Expected accepted shares are 625 and expected residual shares are 375:
The $47.75 estimate is below the $50 offer price because not every share is expected to be accepted. It is above the assumed $44 residual value because some shares receive the tender premium.
The actual result can differ. The final proration factor may change after withdrawal and validation, and the market price can move before or after completion.
Using a $50 tender price:
| Acceptance rate | Residual value | Blended value |
|---|---|---|
| 25% | $44 | $45.50 |
| 50% | $44 | $47.00 |
| 62.5% | $44 | $47.75 |
| 75% | $44 | $48.50 |
| 62.5% | $40 | $46.25 |
| 62.5% | $48 | $49.25 |
This table shows why a headline premium alone is insufficient. Both acceptance probability and residual value drive the expected outcome.
Investor.gov explains that a tender offer is a time-limited offer to holders on stated terms and that an offer by a company for its own securities is an issuer tender offer. For a U.S. public issuer, the offer documents and amendments can generally be found through EDGAR, often in a Schedule TO filing.
Review:
| Measure | What it represents | Why it differs |
|---|---|---|
| Blended value | Scenario-weighted holder outcome across accepted and residual shares | Depends on proration and residual-price assumptions |
| Tender premium | Offer price minus a reference market price | Ignores unaccepted shares and post-offer value |
| Weighted-average purchase price | Average price the company actually pays for acquired shares | Measures issuer execution, not the holder’s residual position |
| Intrinsic value | Estimated present value of future owner cash flows | Requires business valuation rather than offer mechanics alone |
| Market price | Current transaction or quoted price | Can change continuously and may not equal either scenario value |
