SDI Limited's Chinese Takeover Bid Comes With Regulatory Uncertainty

A 65% premium takeover offer from Beijing Guoci Kebo Technology has board and founder support, but FIRB approval risk has some fund managers taking profits early.

SDI Limited, a long-established Melbourne-based dental materials manufacturer tightly held by its founder, received a $1.40 per share takeover bid from Beijing Guoci Kebo Technology representing a 60 to 65 percent premium, a fully cash offer unanimously recommended by the board, though FIRB approval risk on the Chinese buyer prompted at least one fund manager to begin exiting.

A tightly held, founder-controlled dental manufacturer

DMX Asset Management described SDI as a long-established Melbourne-based manufacturer of dental materials, distributing and selling its products around the world, a relatively small company with a market value of around $120 million, tightly held with its founder owning 43 percent and the register otherwise tightly held with very low institutional participation, noting daily liquidity is low but the fund took advantage of a window of opportunity to buy.

A weak result overshadowed by a 60-65% premium takeover bid

Merewether Capital said SDI reported revenue up 3 percent and net profit down 2 percent, a disappointing result but not worth discussing in much detail since the company also announced a takeover bid alongside its half-year results, with the $1.40 bid price representing around a 60 percent increase on where the share price was trading pre-result, a fully cash bid supported by the board.

FIRB risk prompts a cautious exit, even as shares rally over 40 percent

DMX Asset Management said the stock rose over 40 percent on the takeover announcement, contributing 1 percent to NAV, describing a Melbourne-based manufacturer, distributor and marketer of dental materials whose long-term growth objectives had required major expansion of production facilities requiring significant upfront investment expected to yield greater returns. NorthStar Impact Funds said SDI entered into a Scheme Implementation Deed with Beijing Guoci Kebo Technology under which shareholders will receive $1.40 per share, representing a 65 percent premium to the pre-announcement share price, with the board unanimously recommending shareholders vote in favour and SDI's largest shareholder, the chair with 45.9 percent, confirming his support. Merewether Capital said that given the weaker than expected report and an FIRB risk it professed to have no skill in assessing, it began exiting its position at a slight discount.

What fund managers say they are watching next is whether FIRB approval is granted for the Beijing Guoci Kebo Technology acquisition given the Chinese buyer, completion of the scheme given the board's unanimous recommendation and 45.9 percent shareholder support, and whether the deal proceeds at $1.40 per share or faces regulatory hurdles.
