Overview
Altaba Inc. was a U.S. investment management company created from the corporate remains of the original Yahoo! Inc. after Verizon Communications acquired Yahoo's principal internet operations in 2017. It was not the continuation of Yahoo's consumer-facing portal, search, mail, news, finance, or other online services. Instead, it became a non-diversified, closed-end management investment company whose purpose was to manage, monetize, and ultimately distribute the assets that Verizon had not acquired. The company originated in the early history of Yahoo. Jerry Yang and David Filo created an organized directory of websites in 1994, initially called Jerry and David's Guide to the World Wide Web. The service was renamed Yahoo! in April 1994, and the Yahoo.com domain was registered in January 1995. Yahoo expanded rapidly into a major web portal and technology company, building a large portfolio of consumer internet products and making numerous acquisitions. Its value surged during the dot-com era, but the company later faced strategic, competitive, and operational difficulties. Important events in the pre-Altaba period included the rejection of Microsoft's acquisition proposal in 2008, repeated chief executive changes, workforce reductions, and the disclosure of major data breaches affecting hundreds of millions of accounts. In July 2016, Yahoo agreed to sell its core internet business to Verizon. Verizon completed the acquisition on June 13, 2017, transferring the operating assets into Yahoo! Holdings, a Verizon subsidiary within Oath, the division later associated with the modern Yahoo business. The former Yahoo! Inc. retained cash, partnership investments, a bond portfolio, minority equity positions, and intellectual-property assets that were outside the transaction. On June 16, 2017, the remaining company changed its name to Altaba Inc. and reorganized around investment management and asset disposition. Its shares traded on Nasdaq under the symbol AABA. Altaba's most significant holdings included a substantial interest in Alibaba Group and a stake in Yahoo Japan Corporation. It also held or had held positions in companies and assets including Hortonworks, Gomaji, Envestnet, Rimage Corporation, SeatGeek, Protagenic Therapeutics, Eastman Kodak Company, Paperless Post, and Snap. Excalibur IP, an Altaba-owned patent business, represented another important residual asset. The company used external investment advisers including BlackRock Advisors and Morgan Stanley Smith Barney. The post-Yahoo company progressively sold its investments rather than developing new consumer products. In late 2018 it announced the sale of its Yahoo Japan interest to SoftBank Group and authorized a large share repurchase program. In April 2019, Altaba announced plans to sell its Alibaba stake and wind down. Its Nasdaq trading ended on October 2, 2019, and it filed a Delaware certificate of dissolution on October 4 under a plan of complete liquidation and dissolution. Some funds were retained for potential tax obligations connected with the Alibaba transaction. In 2020, the Excalibur IP patent portfolio was sold to RPX Corporation. Altaba therefore ended as a liquidation and investment vehicle rather than as an ongoing operating brand.
History
Altaba was the legal and investment-management successor to the portion of Yahoo! Inc. that remained after the sale of Yahoo's operating internet business to Verizon Communications. Understanding Altaba requires separating the company from the modern Yahoo consumer brand: Verizon acquired the operating assets and placed them in Yahoo! Holdings, while the former public company retained assets that were not included in the transaction. Yahoo began in January 1994, when electrical-engineering graduate students Jerry Yang and David Filo created a hierarchical directory of websites. Originally called Jerry and David's Guide to the World Wide Web, it was renamed Yahoo! in April 1994. The Yahoo.com domain was registered in January 1995. The service grew from a directory into a broad web portal offering search, email, news, finance, advertising, and other online services. Yahoo expanded through acquisitions and became one of the most recognizable internet companies of the 1990s and 2000s. The company experienced both extraordinary growth and substantial strategic pressure. Its market valuation rose sharply during the dot-com bubble, followed by a severe decline when the bubble burst. Yahoo rejected Microsoft's acquisition proposal in 2008. During the following years it changed chief executives several times, reduced its workforce, and attempted to rebuild its consumer internet and mobile businesses. Under Marissa Mayer, Yahoo continued to evaluate acquisitions and partnerships, including interest in Hulu, while dealing with competitive pressure from Google, Facebook, and other technology companies. Yahoo's later years were also marked by major cybersecurity incidents. In September 2016, the company disclosed a breach involving information connected with at least 500 million accounts. In December 2016, it disclosed a separate breach affecting more than one billion accounts and dating to 2013. The incidents became important to the Verizon transaction and generated litigation and regulatory scrutiny. In July 2016, Yahoo agreed to sell its core internet business to Verizon. The transaction closed on June 13, 2017. Verizon acquired the operating services and related assets, while the old Yahoo company retained cash, partnership interests, a bond portfolio, certain patents, and other investments. On June 16, 2017, the remaining company changed its name to Altaba Inc. and adopted the structure of a non-diversified, closed-end management investment company. Its shares traded on Nasdaq under AABA. Altaba's main strategic task was not product development but portfolio management and liquidation. Its most important assets included a large Alibaba Group holding and an interest in Yahoo Japan Corporation. It also maintained or had maintained investments in companies such as Hortonworks, Gomaji, Envestnet, Rimage Corporation, SeatGeek, Protagenic Therapeutics, Eastman Kodak Company, Paperless Post, and Snap. Excalibur IP, an Altaba-owned patent company, controlled a significant intellectual-property portfolio. External investment advisers included BlackRock Advisors and Morgan Stanley Smith Barney. Altaba announced the sale of its Yahoo Japan interest to SoftBank Group in September 2018. In April 2019, it announced the planned sale of its Alibaba interest and a complete wind-down. Nasdaq trading ended on October 2, 2019, and the company filed a Delaware certificate of dissolution on October 4. Residual funds were retained for potential tax liabilities associated with the Alibaba sale. The Excalibur IP patent portfolio was sold to RPX Corporation in 2020. Altaba consequently ended as a closed-end investment and liquidation vehicle, with no continuing consumer internet operations.
