Masayoshi Son and Greg Hayes: Careers and Current Roles

Masayoshi Son and Greg Hayes are business leaders associated with very different organisations: Son founded SoftBank, while Hayes led United Technologies and subsequently RTX. The useful connection between their names is a comparison of corporate careers. The primary records reviewed for this article do not establish a personal relationship or a joint venture between them.

The most important current distinction is that Son remains SoftBank Group’s chairman and chief executive in its published leadership information, whereas Hayes should not be described as RTX’s current chief executive or chairman. RTX announced his departure from the executive chairmanship effective 30 April 2025. This guide was checked on 20 October 2026 and separates present roles from historical titles.

Who is Masayoshi Son?

SoftBank Group’s official biography of Masayoshi Son identifies him as representative director, corporate officer, chairman and CEO. It records the founding of Nihon SoftBank, now SoftBank Group, in September 1981. That founding role is central to understanding why his name is so closely associated with the company’s long-term direction.

The same biography lists his chairmanship and directorship at Arm Holdings from August 2023. These titles concern separate companies within a wider business context, so they should be named precisely. A reference to SoftBank can mean the listed group or another business carrying the brand; it is worth checking the full legal company name before attaching a particular role to him.

Son is therefore best introduced through his documented leadership responsibilities rather than through a fluctuating wealth estimate. Personal net worth, company market value and the size of an investment portfolio measure different things. Combining them would produce a misleading account of either his finances or the resources directly available to a company.

Who is Greg Hayes?

Greg Hayes is the familiar name used for Gregory J. Hayes. His career is closely connected with United Technologies Corporation and the aerospace and defence group now known as RTX. RTX’s own succession announcement records that he became UTC’s chief executive in 2014 and its chairman in 2016, before leading the combined business formed in 2020.

The company’s February 2025 leadership announcement describes his progression from chief executive to executive chairman in May 2024. It then sets out the next transition: leaving the executive chairmanship and board effective 30 April 2025, followed by a special adviser role scheduled to run through 2 January 2026.

Those dates matter because an old profile can be accurate about an earlier period and still be unsuitable as a description of today. A reader encountering “RTX CEO Greg Hayes” should check the publication date. The wording may describe a historical event rather than the company’s current management structure.

What are their current leadership positions?

SoftBank’s published information continues to identify Son with the group’s chairman and CEO positions. By contrast, RTX’s current leadership page identifies Christopher T. Calio as chairman and chief executive. That is the appropriate starting point when checking who leads RTX now.

Hayes’s previously announced advisory period should not be extended beyond its stated end date without new evidence. A biography that still reproduces the old timetable is not proof of a renewed appointment. Equally, ending one company role does not establish that someone has retired from every professional activity. This article makes neither assumption.

When checking an executive title, match the person, organisation, role and date. Missing any one of those details can create a false impression. “Chairman” at one entity, for example, does not automatically mean chairman of its parent, a former subsidiary or another similarly named business.

Two different ways to understand corporate leadership

A useful comparison begins with the organisations rather than with personality labels. A founder-led group invites questions about investment priorities, governance and how control is exercised across related companies. An industrial operating group invites questions about products, delivery commitments, manufacturing capacity and the responsibilities of its separate business units.

This is an analytical framework, not a claim that either leader uses only one management method. Both investment decisions and operational execution can matter within the same company. The framework simply helps readers choose relevant evidence instead of treating every prominent business figure as interchangeable.

For example, a change in a portfolio holding and a change in an aircraft programme belong to different kinds of business analysis. The first may require ownership disclosures and investment documents; the second may require programme information, customer announcements and operating results. A headline about one should not be used to explain the other without an explicit link.

Are Masayoshi Son and Greg Hayes connected?

The records reviewed here establish separate corporate careers. They do not establish a family relationship, a private friendship, a shared business venture or an announced partnership between the two men. A search phrase containing both names is not evidence that such a connection exists.

This distinction is particularly useful when a page combines unrelated public figures for comparison. Readers can still compare leadership responsibilities, succession histories and business contexts, but the comparison should be presented openly. A photograph montage or a shared headline must not be mistaken for evidence that the people attended an event together.

If a future report claims a specific partnership, look for a dated announcement that names the organisations, explains the transaction and states the participants’ roles. A vague mention of technology, aviation or artificial intelligence would not be enough on its own to establish a direct relationship between individuals.

Why company names and dates matter

SoftBank Group’s corporate profile provides a separate reference point for the organisation itself. Using an executive biography alongside a corporate profile helps distinguish a person’s career from the structure of the business being discussed. Neither document should be treated as a complete independent assessment of management performance.

The same principle applies to corporate name changes and reorganisations. An executive may have led a predecessor business, then the merged organisation, and later a board transition. A concise biography can compress those steps so heavily that readers lose the sequence. Restoring the dates is often more helpful than adding a longer list of achievements.

For a practical research note, write the title exactly as the source gives it and add the relevant date beside it. Then record whether the source describes an appointment, an intended transition or a position already in effect. This avoids turning a future announcement into a completed event prematurely.

How to compare their records fairly

Start with a specific question. Are you comparing company strategy, governance, succession planning or career progression? Choose material that answers that question. A collection of quotations about leadership is less useful if it never explains what responsibility each executive actually held at the time.

Keep corporate results separate from personal attribution. A company’s performance reflects employees, customers, market conditions, assets and decisions made over many years. Describing a result as the work of one individual requires more evidence than the fact that the person held the top job when it occurred.

Also distinguish an official company account from an independently tested conclusion. Corporate biographies are strong sources for appointments and career chronology. They are less suitable for proving that a leader was uniquely successful, universally respected or responsible for every positive outcome. Those broader claims need a different evidential basis.

Questions readers often ask

Is Greg Hayes still the CEO of RTX?

No. RTX’s current leadership information names Chris Calio as chairman and chief executive. Hayes’s CEO tenure belongs to the company’s earlier leadership history.

Is Masayoshi Son the founder of SoftBank?

Yes. SoftBank Group’s biography records that he founded Nihon SoftBank in 1981. It also lists his present group leadership titles.

Does this comparison establish a personal relationship?

No. It explains two separately documented careers. No personal or commercial relationship between Son and Hayes is established by the sources used here.

The practical takeaway is to read these names through precise company records: Son’s continuing founder leadership at SoftBank Group and Hayes’s historical leadership and succession at RTX. That produces a clearer comparison than recycled titles or an invented connection.
