Broadcom announced its planned acquisition of HotHaus Technologies on July 18, 1999, and completed the deal on August 31. The announced value was about $280 million U.S. (then equivalent to $414 million Canadian), paid in Broadcom equity instruments—not cash. Broadcom sought HotHaus’s OpenVoIP embedded communications software and digital signal processor expertise to pair with its broadband chips and advance packet telephony.
What Broadcom acquired
HotHaus was a privately held telecommunications software company specializing in digital signal processor (DSP) software for telecom equipment makers. Broadcom described its product suite as OpenVoIP embedded communications software: it enabled digital voice, fax, and data packets to travel over data networks, including the Internet.
The software supplied voice relay, fax relay, data relay, and telephony signaling, and ran on programmable DSPs. Broadcom identified these intended deployment settings:
- Gateways
- Cable modems and ADSL modems
- Remote-access servers
- LAN PBXs
- Internet appliances
At the time of the announcement, Broadcom described HotHaus as a 70-person company headquartered in Vancouver, with systems engineering in Toronto and offices in San Jose, Boston, and Dallas.

Why Broadcom pursued HotHaus
The acquisition was meant to combine two complementary capabilities: Broadcom’s broadband chips and HotHaus’s communications software and DSP expertise. Broadcom CEO Henry T. Nicholas III said the goal was to offer a combined hardware-and-software solution for carrying voice over broadband packet networks.
Contemporaneous coverage linked the deal to Broadcom’s push into IP telephony. EDN reported that HotHaus would join Broadcom’s Cable Business Unit and that founder Ross Mitchell would continue managing the Vancouver operation. It also described a plan to move Open VoIP from reliance on general-purpose DSPs toward dedicated Broadcom silicon—a way to connect the acquired software to Broadcom’s chip roadmap.

How much the acquisition was worth—and how it was paid
Broadcom announced a value of approximately $280 million U.S., or $414 million Canadian. The valuation was calculated using Broadcom’s Nasdaq closing price on July 16, 1999, so it represented the value of stock-based consideration at that market price, not a cash purchase price.
HotHaus shareholders could elect Broadcom Class B common stock or exchangeable preferred stock issued by a Broadcom Canadian subsidiary. The preferred stock was exchangeable one-for-one for Class B shares. Broadcom reserved 2.0 million Class B shares for HotHaus exchanges and option exercises.

Broadcom’s August 31 closing announcement reported 3,361,571 Class B shares issued across the HotHaus and AltoCom acquisitions, with another 258,263 shares reserved for employee options and other rights across those two transactions. Those combined figures should not be read as HotHaus-only share totals.
When the deal closed
| Date | Event |
|---|---|
| July 15, 1999 | Acquisition agreement dated. |
| July 18, 1999 | Broadcom announced the planned HotHaus acquisition. |
| August 31, 1999 | Broadcom announced the closing of the HotHaus and AltoCom acquisitions. |
Broadcom’s September 1999 SEC filing treated the acquisitions as pooling-of-interests transactions. It reported $1.8 million in revenue for the quarter and $8.3 million for the nine months before the August 31 closing, but those figures combine HotHaus and AltoCom and cannot be attributed to HotHaus alone.

- Built-in Bluetooth, Wi-Fi
What the available record establishes
The announcement and closing materials document the deal’s strategic logic, equity-based valuation, and intended product integration. EDN reported that products were expected to ship by year-end 1999, but the cited material does not establish a later standalone performance result for HotHaus or verify what products ultimately shipped. The deal is best understood as Broadcom’s effort to add VoIP software and DSP know-how to its broadband-chip business, rather than as a cash purchase of a standalone VoIP product line.
