Bull-Dog Sauce beat Steel Partners with Japan's first court-upheld poison pill

In May 2007, Bull-Dog Sauce — a Tokyo condiment maker whose history reaches back to the early 1900s — was Japan's newest takeover target. US fund Steel Partners, its biggest shareholder since 2002 with roughly 10.5%, launched a tender offer on May 18 for all shares at ¥1,584 each, about an 18.6% premium and a bid worth around ¥27bn; on June 15 it raised the price to ¥1,700 and extended the deadline to August 10.

Bull-Dog's board fought back with a weapon untested in Japan: a poison pill. Proposed June 7 and approved at an extraordinary meeting on June 24 with 83.4% of the vote, the plan gave holders three warrants per share exercisable at ¥1, while declaring Steel Partners ineligible — the company would buy the fund's warrants at ¥396 each, exactly a quarter of the original tender price, diluting Steel's stake toward 2.82%. Steel called the discrimination illegal and filed an injunction on June 13.

The courts sided with the company all the way: Tokyo District Court rejected the injunction on June 28, the Tokyo High Court on July 9, and the Supreme Court's Second Petty Bench on August 7, 2007 — making the Bull-Dog pill the first takeover defense in Japan to survive all three levels of review and still the template for later defenses.

The decision that mattered was governance, not just litigation: by putting the pill to a shareholder vote, Bull-Dog turned the defense into the owners' choice, which is exactly why the courts upheld it — and why the company, a small soy-sauce maker, kept itself independent from a fund that had arrived with a 10% stake and a tender.

The tender died: shareholders backed the pill with 83.4% of the vote, courts rejected Steel's appeals through the Supreme Court, and the fund's stake fell toward 2.82%

Convening a shareholder vote rather than having the board impose the pill made the discrimination legally defensible — it was the owners' decision, not management self-protection.

The pill was priced against the tender: redemptions at exactly a quarter of the ¥1,584 offer made Steel's exit economics clear while capping Bull-Dog's cost, a structure courts could test and approve.

Japan's takeover regime was untested and hostile to foreign raids, so a clear national precedent — upheld to the Supreme Court in weeks — removed the uncertainty investors had counted on.

Steel Partners' own raid was grabby rather than value-based: it bid a modest premium for control of a niche food company, giving Bull-Dog's defense the moral high ground with Japanese institutions.

When a raider owns 10% and the takeover regime is untested, a shareholder-approved differential poison pill upheld to the Supreme Court is a repeatable defense where market defenses do not exist

Steel Partners pressed on briefly after the Supreme Court ruling but never completed the takeover, and the case became the reference point for every Japanese takeover defense that followed. The poison-pill design Bull-Dog used — warrants with discriminatory redemption, approved by shareholders — became the standard template that Japanese boards cited through the 2010s, while Steel Partners' defeat cooled foreign raider enthusiasm for small-cap Japan until the activism wave of the late 2010s.
