Arbutus Biopharma ($ABUS) completed its $230 million Dutch-auction tender at $5.00 per share, the bottom of its $5.00-to-$5.75 range.
The offer was heavily oversubscribed. Ordinary shareholders who tendered at or below the clearing price had only about 55.6% of their shares accepted. Qualifying odd-lot holders were exempt from proration and had all of their properly tendered shares purchased.
For the 99-share paper position we recorded in September, the odd-lot preference worked exactly as intended. The trade still lost money.
| Arbutus Paper Trade | Result |
|---|---|
| Reference purchase price | $5.17 |
| Shares | 99 |
| Initial cost | $511.83 |
| Final tender price | $5.00 |
| Tender proceeds | $495.00 |
| Gross loss | -$16.83 |
| Gross return | -3.3% |
The Odd-Lot Preference Was Valuable
Arbutus accepted 46 million shares, representing roughly 23% of the shares outstanding before the tender. Shareholders tendered substantially more stock than the company was willing to buy.
That is exactly the situation in which an odd-lot preference matters. A shareholder in the ordinary tender pool had only about 55.6% of an eligible position purchased. A qualifying holder of 99 shares who tendered the entire position had all 99 accepted.
The difference is meaningful. Without odd-lot priority, a 99-share holder subject to the general proration rate would have had roughly 55 shares purchased and been left holding the rest.
The Problem Was the $5.00 Clearing Price
When we added Arbutus to our September odd-lot tender portfolio, ABUS had closed at $5.17. The tender could clear anywhere from $5.00 to $5.75.
That made Arbutus different from a tender where the minimum price already offers a positive spread. A purchase at $5.17 had downside even if every share was accepted.
The auction ultimately cleared at the floor. Buying 99 shares at $5.17 would have cost $511.83. Tendering all 99 at the final $5.00 price produced $495, for a gross loss of $16.83 before commissions, corporate-action fees or taxes.
A shareholder who instead insisted on a tender price above $5.00 would have avoided selling at a loss, but Arbutus purchased no auction tenders submitted above the final clearing price.
Odd-Lot Protection Is Protection From Proration
The result illustrates the narrow value of the odd-lot provision. It can improve execution when an offer is oversubscribed. It does not protect against paying too much for the shares before the tender closes.
Arbutus is a useful contrast with our Computer Modelling Group tender postmortem. In CMG, the market price we recorded was below the bottom of the tender range, and the auction later cleared at the top. Arbutus began with the opposite problem: our $5.17 reference price was already above the $5.00 floor.
The odd-lot provision still had real value. It prevented substantial proration. It simply could not overcome an unfavorable purchase price relative to the final tender price.
Arbutus’s final tender results confirm the $5.00 purchase price, 46 million shares repurchased, approximately 55.6% ordinary proration and full protection from proration for qualifying odd lots.
