The acquisition battle for Shibaura Electronics reached its peak in 2025. Japan’s precision machinery manufacturer MinebeaMitsumi and Taiwan’s electronic components giant YAGEO competed to control Shibaura Electronics. Ultimately, MinebeaMitsumi’s tender offer (TOB) failed, while YAGEO gradually gained the upper hand. This article summarizes the background, objectives, acquisition terms, and timeline of the battle, along with brief analysis.
Acquisition Battle Overview: Minebea Fails, YAGEO Takes Lead
- YAGEO’s final offer: JPY 7,130 per share, totaling several hundred billion yen.
- MinebeaMitsumi’s final offer: JPY 6,200 per share.
- Result: Minebea obtained only about 20% of shares, failing to meet the 50.01% threshold, and its TOB was unsuccessful.
- Key factor: YAGEO obtained approval under Japan’s Foreign Exchange and Foreign Trade Act (FEFTA), extended the tender period, and leveraged capital and distribution network advantages.
This acquisition not only affected the future of Shibaura Electronics but also highlighted the regulatory and strategic challenges foreign investors face when acquiring Japanese tech companies.

Background and Strategic Objectives of the Parties
MinebeaMitsumi
- Main businesses: bearings, automotive parts, electronic motors, semiconductors, and sensors.
- Joined as a “white knight” at Shibaura Electronics’ request, gaining support from the board.
- Objectives:
- Integrate Shibaura’s NTC thermistor technology with Minebea’s products.
- Strengthen global competitiveness in the sensor business.
- Protect key Japanese technology from foreign acquisition.
- One of the world’s largest chip resistor manufacturers, actively expanding its sensor business.
- Acquisitions include Heraeus Nexensos, Telemecanique Sensors, and KEMET.
- Sensor business revenue reached USD 400 million in 2024.
- Objectives:
- Expand Shibaura Electronics’ products internationally via YAGEO’s global network.
- Increase market share in NTC thermistors (Shibaura holds 13.5% globally).
- Strengthen R&D and production capabilities.
- Japanese sensor manufacturer, world leader in NTC thermistors.
- High demand in automotive, environmental monitoring, and energy sectors.
- Initially supported Minebea as a “friendly” acquirer but faced strong price competition from YAGEO, shifting market preference toward the latter.
Acquisition Terms Comparison
- Price Evolution:
- MinebeaMitsumi: JPY 4,500 → 6,200 per share.
- YAGEO: JPY 4,300 → 6,635 → 7,130 per share.
- Acquisition Method: All-cash tender offers, no share swaps.
- Minimum Threshold: Both required 50.01% (7,539,900 shares); failure to reach meant the offer was unsuccessful.
- Regulatory Review: YAGEO was subject to Japan’s FEFTA review, eventually approved on September 2, extending the tender period to September 18.
- Company Position: Shibaura’s board supported Minebea’s TOB and opposed YAGEO’s proposal.
Timeline of the Acquisition Battle
- Feb 5, 2025: YAGEO initiates hostile TOB at JPY 4,300 per share.
- Apr 10, 2025: Minebea announces TOB at JPY 4,500 per share, gaining board support; tender period starts Apr 23.
- May 2025: Minebea (May 2) and YAGEO (May 9) begin acquisitions.
- Jun 25, 2025: YAGEO obtains Taiwanese government approval, extending the period to Jul 9.
- Aug 14, 2025: Minebea raises price to JPY 6,200, extends period to Aug 28.
- Aug 21, 2025: YAGEO increases to JPY 6,635, extends to Sep 4.
- Aug 23, 2025: YAGEO further raises to JPY 7,130, extends to Sep 8.
- Sep 2, 2025: Japan approves YAGEO’s FEFTA application, extending deadline to Sep 18.
- Sep 11, 2025: Minebea TOB closes; only 20% of shares tendered, offer fails.
- Sep 12, 2025: Minebea officially announces TOB failure; YAGEO continues until Sep 18.
Analysis and Outlook
- Price Difference Determined Outcome: Investors ultimately favored YAGEO’s higher offer, reflecting a market preference for maximizing shareholder value.
- Challenges for Foreign Acquisition of Japanese Companies: FEFTA review was critical. YAGEO’s approval shows selective openness to foreign investment in technology sectors.
- Future of Shibaura Electronics: If YAGEO completes the acquisition, Shibaura’s products will gain broader international reach, potentially boosting market share.
- Implications for Japanese Industry: Minebea, despite acting as a “white knight,” could not compete with YAGEO’s capital strength, highlighting the decisive role of financial power in global M&A battles.
Conclusion
The Shibaura Electronics acquisition case reveals the interplay of capital, regulation, and international strategy. While Minebea had board support, it lacked the funding to win; YAGEO leveraged financial resources and global networks to move toward victory. This case provides insights for Taiwanese and Japanese companies facing foreign acquisition offers in the future.
