What Is GMHIW? The SPAC Warrant That Enabled LiDAR Scaling
GMHIW was the ticker for the public warrants of Gores Metropoulos, Inc. (share ticker GMHI), which raised about $400 million in its 2019 IPO. Each IPO unit included one Class A share plus a fraction of a warrant. The warrants detached and traded separately, giving holders the right to purchase one share of the post-merger company at $11.50.
On December 2, 2020, Gores Metropoulos completed its business combination with Luminar Technologies in a deal with an implied pro forma equity value of approximately $3.4 billion. The combined company adopted the LAZR ticker, and GMHIW transitioned to LAZRW. By March 2021, nearly 99% of the public warrants had been exercised, generating roughly $154 million in cash proceeds for Luminar.
This capital infusion directly funded R&D, semiconductor fabrication, and production ramp-up for Luminar’s Iris LiDAR sensor—the first high-performance automotive-grade LiDAR standardized on a global production vehicle like the Volvo EX90.
Key takeaway: Warrants like GMHIW create leveraged upside for investors while delivering exercise cash straight to the operating company, helping solve funding challenges for complex sensor technologies in the autonomous era.
GMHIW Warrant Mechanics
SPAC warrants such as GMHIW function as detachable rights with specific features designed for blank-check companies. Here is the clear, sequential process:
- IPO and Unit Structure — Gores Metropoulos sold units at $10 each, typically including one Class A share and a fraction of a warrant. GMHIW traded independently on Nasdaq, offering liquidity and leverage.
- Trust Account and Shareholder Protections — The majority of IPO proceeds were held in escrow. Public shareholders could redeem shares near $10 plus interest if they disapproved of the target (Luminar).
- Merger Announcement and Approval — The deal with Luminar was announced in August 2020 and closed on December 2, 2020, after shareholder vote.
- Warrant Exercise or Redemption — Post-merger, holders could exercise at $11.50 per share (cash or cashless in certain cases). Strong stock performance often triggered company redemption rights for unexercised warrants at $0.01 to clean up the capital structure.
- Capital Delivery — Exercised warrants injected direct cash—approximately $154 million in this case—into Luminar for technology scaling.

Impact on Luminar LiDAR Development
The GMHIW-facilitated merger, combined with a $170 million PIPE, provided Luminar the resources to industrialize its 1550nm wavelength LiDAR platform. Iris used eye-safe lasers, dual-axis MEMS scanning, and custom ASICs to deliver long-range, high-resolution performance.
Core Working Mechanism of Luminar’s LiDAR (Simplified):
- Laser Emission: 1550nm pulses scan the environment via compact mirrors without spinning the entire unit.
- Reflection and Detection: High-sensitivity receivers measure time-of-flight with picosecond accuracy.
- Point Cloud Generation: Millions of points per second create detailed 3D maps, even for low-reflectivity objects at night.
- AI Processing and Fusion: On-edge computation classifies objects with low latency; data fuses with cameras and radar for redundant perception.
- Automotive Integration: Designed for SAE Level 3+ applications, with dynamic field-of-view adjustments.
Iris offered ranges up to 250m+ for dark objects and 600m for larger ones, with a 120° horizontal field of view—advantages in challenging conditions like fog or low light compared to many camera-only or 905nm systems.
The warrant exercise capital helped achieve production milestones, including “run at rate” manufacturing and qualification for series production. Later, Luminar developed the Halo sensor platform: roughly 1/3 the size and half the power of Iris, with up to 4x performance improvement, 2x point density, and significantly lower cost. Halo targeted sleeker integration (roofline or behind-windshield) and broader adoption in mainstream vehicles.
