TD Securities (USA) LLC reported a 4.6% stake in GCT Semiconductor Holding, Inc., according to a Schedule 13G/A filed Friday. That’s 3,456,392 shares—all but a sliver linked to warrants, the filing said. The update comes as investors continue to watch if the small-cap chip designer’s 5G pipeline is shifting out of test mode into actual shipments.
Why it matters now: GCT reported this week it shipped 3,000 5G chipsets during the first quarter, a 58% jump over the previous three months, and stuck to its outlook calling for quarterly 5G shipment gains through 2026. Notable, given first-quarter sales still came in at just $1.9 million.
Trading picked up in GCT shares, which changed hands at $1.83 Friday afternoon. That price gives the company a roughly $121 million market value, market data show.
TD’s filing stands out for its structure. Warrants attached give holders the choice to pick up shares at $11.50—out of the money as of Friday’s close. TD’s direct common share tally barely hits 3,997, but if you add in the warrants, another 3.45 million shares could come into play.
The filing also noted the securities were picked up as part of regular business activities, not as a play to shake up or steer control at GCT. In short, it’s a standard disclosure, not activist maneuvering.
Earnings season is just getting underway. GCT reported revenue climbing to $1.92 million, up from $496,000. Net loss, though, expanded to $9.86 million from $6.97 million. Operating loss improved a bit, narrowing to $6.13 million compared with $7.74 million.
Chief Executive John Schlaefer said GCT “entered a new phase defined by increasing customer shipments” in the quarter. Chief Financial Officer Edmond Cheng described the period as a “meaningful step,” though he emphasized that results “remain modest” compared to the company’s mid- and long-term targets. Business Wire
Caution is understandable here. In its 10-Q, GCT recorded a modest $100,000 in 5G platform product sales for the quarter, compared with $1.4 million from 5G service revenue. Service fees tend to fluctuate, leaving the company’s push toward more reliable product income as the key hurdle.
In a sponsored note dated May 14, Lisa Thompson at Zacks Small-Cap Research forecasted the sequential ramp would push ahead, predicting “more sales of products and fewer of services.” She tagged the stock with a $4.40 valuation, tying that number to a 2027 revenue estimate of $95 million. It’s worth noting: Zacks SCR discloses that it gets paid by issuers for research coverage.
The landscape is ruthless. Back in February, Zacks called Qualcomm the dominant force in the same segment GCT is aiming for, and described GCT as one of just a handful of companies that could supply those specific 4G and 5G telecom and IoT device needs — though this doesn’t include the majority of smartphones. So GCT is limited to chasing after more niche design wins, rather than challenging the handset modem giants head-on.
Satellite connectivity factors heavily here. GCT, on May 7, announced a reference platform deal with one of the biggest names in satellite communications—a move that builds on a licensing pact struck in January and aims to accelerate next-gen equipment. The customer wasn’t identified, but Schlaefer called the agreement proof of the partner’s “trust” in GCT tech. Business Wire
The real challenge sits on the balance sheet. As of March 31, GCT reported just $7.2 million in cash and cash equivalents, stacked up against $52.1 million in borrowings set to come due within a year. Management flagged the urgent need to deliver positive cash flow, secure fresh capital, and work out new terms with creditors. “Substantial doubt” hangs over GCT’s ability to keep operating, the company admitted.

Further fundraising poses dilution risk for shareholders. GCT warned that more sales of stock, convertible notes, or warrants might erode current owners’ stakes. The company’s 10-Q also showed $7.4 million in cash burned through operating activities during Q1.
For now, it’s not TD’s holding that’s driving the stock—the focus is execution: locking in new 5G product orders, getting more satellites shipped in the back half, and managing the money side without sacrificing big gains. The 13G/A brings another holder into the mix, but the uncertainty about the ramp remains.
