AXT, Inc. (NASDAQ: AXTI) has completed a significant capital raise, with underwriters exercising their option to purchase an additional 1.28 million shares at $64.25 each, bringing in approximately $82.5 million. This addition pushes the total gross proceeds from the public offering to around $632.5 million, before underwriting discounts and expenses. The semiconductor materials supplier, headquartered in Fremont, California, is channeling the bulk of these funds into expanding indium phosphide (InP) wafer production at its Beijing Tongmei subsidiary in China.
Capital Infusion for AI Data Center Demand
The offering comes at a time when investor appetite for companies tied to AI data-center infrastructure is robust. InP is a critical compound semiconductor used in high-speed laser-based data links that facilitate the massive data transfers required by data centers and telecom networks. AXT plans to allocate most of the proceeds to Beijing Tongmei Xtal Technology Co., Ltd., which is scaling up InP substrate production for export markets. The remainder will support research and development, working capital, and other general corporate purposes.
The base offering of 8,560,311 shares closed on April 22, with Northland Capital Markets serving as sole bookrunner. Co-managers included Needham & Company, B. Riley Securities, Craig-Hallum, and Wedbush Securities. The raise is substantial relative to AXT's 2025 revenue of $88.3 million, which comprised $58.9 million from substrates and $29.4 million from raw materials and other segments. This underscores the scale of new capacity investors are being asked to finance before it generates sales.
Preliminary First-Quarter Outlook
AXT has not yet released its first-quarter results, but management provided preliminary guidance in the prospectus supplement. Revenue for the March quarter is expected to be between $26 million and $28 million, with a net loss ranging from $1.6 million to $2.6 million, or a per-share loss of 3 to 5 cents. The company cautioned that these figures are preliminary and subject to change upon final closing. The official first-quarter report is scheduled for release after the market closes on April 30, followed by an earnings call at 1:30 p.m. Pacific that same day.
Market Performance and Trading Activity
AXT shares closed at $76.16 on April 24, up 1.18% on the day, though the session was volatile, with prices swinging between a high above $81 and a low near $69. This volatility has drawn increased attention from traders focused on the optical-connectivity space, as AXT's wafer products are essential for high-speed data transmission.
AXT does not manufacture chips; instead, it produces wafers from InP, gallium arsenide, and germanium, which are used when standard silicon falls short in speed, thermal tolerance, or optical performance. All of AXT's substrate and raw-material products are manufactured in China by its subsidiaries and joint ventures.
Competitive Landscape and Export Risk
The company operates in a competitive market, with key rivals including Sumitomo Electric Industries, JX, and Freiberger Compound Materials. Customers typically maintain at least two qualified substrate suppliers, making delivery times and reliability critical for market share. However, AXT faces a significant regulatory risk: China's export rules require permits for every Tongmei wafer-substrate product line. While permits are in place for InP exports to Europe, Japan, the UK, and Canada, permits for U.S. buyers remain under final review and none had been granted at the time of the prospectus filing. The company warned that delays in export permits could widen the gap between purchase orders and revenue recognition under U.S. accounting rules, potentially materially impacting its business, financial condition, and operating results.
Despite the strong demand driven by AI, the unresolved export permit issue remains a key overhang for AXT's growth story. Investors are closely watching for updates on the permitting process as the company ramps up its InP capacity to meet surging demand.
