1993 · announced consideration
BBA planned HAEFELY acquisition
110m CHF
announced Haefely group transaction
Limit: Announcement, not archived actual settlement; some consideration deferred to 1995.
Home / Company
Ownership / finance / scale
A company of
many chapters.
The family-founded workshop changed owners and corporate structure many times. The real history is more nuanced than a single valuation or employee-growth curve.
Transactions / never a single stock-price graph
What changed hands?
Original currencies and scopes are preserved. One entry describes an acquisition announcement, another a whole group, another a business-line purchase; none is silently normalized to an identical asset.
1997 · reported transaction
CVC-led sale Haefely Trench
164m GBP
Haefely Trench group (not Basel HV unit alone)
Limit: Not directly comparable with Swiss HAEFELY legal entity or 1999 asset purchase.
1999 · closed purchase
Hubbell closed HV/EMC business purchase
25m USD
HV test and instrumentation business, not full Haefely Trench
Limit: Purchases assets/business scope; cannot infer individual seller proceeds.
2004 · reported transaction
Siemens acquires Trench
340m USD
Trench group, EXCLUDING Haefely test business
Limit: Different company and scope, not a HAEFELY resale.
2019 · closed sale
Hubbell sells Haefely Test AG
38.1m USD
HAEFELY Test AG, Hubbell disposition
Limit: Hubbell SEC stated amount despite buyer press declaring price undisclosed.
2019 · pre tax accounting gain
Hubbell pre-tax accounting gain on disposition
21.7m USD
seller accounting gain, not deal value
Limit: Do not sum with transaction prices or describe as personal proceeds.
The 2019 pre-tax gain reported by Hubbell is a seller's accounting result, not the amount paid to any individual HAEFELY executive. Historical acquisition prices are never treated as personnel compensation.
Scale / evidence-based, not a fabricated continuous chart
How big was HAEFELY?
These observations refer to different legal entities and geographical scopes. They are deliberately presented as separate labelled cohorts instead of a misleading growth line.

HAEFELY global as recalled by requester
Almost 300 staff figure requires HR statement with date, scope and payroll definition. No bar plotted.
“Around 300 employees today” remains a lead awaiting a dated HAEFELY global HR count. PFIFFNER Group headcounts must not be shown as HAEFELY headcounts.
One name, different businesses
The return
to Swiss
ownership.
The 2019 sale to the PFIFFNER family-owned group can be described accurately. Claiming that one specific individual caused earlier decline, or personally profited from a transfer, requires evidence that is not currently available for publication.

2019
A Swiss ownership chapter reopened. Revival should be evaluated on market, product and staff evidence, not assumed from family ownership alone.
