China SXT Pharmaceuticals, Inc. (NASDAQ: SXTC) has filed a Form F-3 — a shelf registration statement used by foreign private issuers to register securities for future sale — covering 157,500,000 Class A Ordinary Shares for resale by a single counterparty, Smart Mart Limited. That block is approximately 49 times the company's estimated tradeable float of 3.2 million shares. ShareStructure assigns the company a dilution risk score of 10 out of 10: EXTREME.
The Convertible at the Center
The shares stem from a Securities Purchase Agreement signed July 3, 2026, structuring what amounts to a prepaid-forward convertible — a financing vehicle in which the company receives cash upfront and delivers shares over time at a formula price. Smart Mart's conversion price is set at 50 percent of the lowest closing price over the trailing 180 trading days, meaning the buyer locks in half of whatever nine-month low the stock prints, subject only to a $0.20 floor. The prospectus itself designates Smart Mart as an underwriter under Section 2(a)(11), signaling the shares are registered to be resold into the open market rather than held.
The 9.99 percent beneficial ownership cap does not limit total issuance. It simply forces a sell-then-reconvert cycle: the holder sells shares to drop below the cap, then converts again. Over time, the full 157.5 million shares can flow through that gate.
A Float That Screens Ten Times Too Large
Major data services report SXTC's float at roughly 32.2 million shares — essentially equal to their shares-outstanding figure. Both numbers are stale. The F-3 cover dated July 7, 2026 shows 38,218,077 Class A shares outstanding. Of those, approximately 35 million are restricted Regulation D shares — securities sold in a private placement exempt from public registration — issued in a May 2, 2026 PIPE and a subsequent cashless warrant exercise. Strip those out, remove the four insider-held Class B shares, and the genuinely tradeable float shrinks to roughly 3.2 million. Data-service figures overstate free-trading supply by about 10x.
Layered Overhang
The Smart Mart convertible is not the only supply channel. A $100 million at-the-market facility — a program allowing the company to sell shares directly into the market at prevailing prices through a broker — signed June 1, 2026 with Univest Securities sits fully undrawn. Behind it, $589 million of remaining capacity on the company's shelf registration dwarfs the roughly $79 million market capitalization by a factor of 7.5. Additionally, 444,444 pre-funded warrants — warrants with a near-zero exercise price that function almost identically to issued shares — remain exercisable at any time.
The Reverse-Split Cycle
SXTC has executed five reverse splits since 2021: 1-for-4, 1-for-20, 1-for-25, 1-for-8, and 1-for-150. The cumulative compression is roughly 600,000-to-1. Each consolidation has been followed within months by renewed issuance. The most recent cycle illustrates the pattern starkly: shares outstanding stood at 958,077 on March 31, 2026, then grew to 38,218,077 by July 7 — a roughly 3,890 percent expansion in fourteen weeks. The single largest driver was a cashless exercise of 3.5 million warrants into 31.5 million shares, a 9-to-1 multiplier from a $3.5 million private placement.
Governance Insulation
A dual-class structure created in July 2025 places all voting control in Class B shares — four shares carrying 50 votes each — held by Feng Zhou Management Limited. Unlimited authorized Class A shares can be issued without diluting that control, removing the shareholder-approval friction that would typically constrain serial equity issuance at a domestic issuer. As a British Virgin Islands foreign private issuer, SXTC is also exempt from Section 16 Form 4 insider-transaction reporting, so any insider sales are not visible in real time.
The F-3 registering the 157.5 million Smart Mart resale shares is marked "Subject to Completion" as of July 7, 2026 — once declared effective, share deliveries under the convertible can begin immediately.
