China SXT Pharmaceuticals, Inc. (NASDAQ: SXTC) has executed six reverse stock splits since February 2021, compounding to a cumulative ratio of approximately 1-for-192,000,000. The most recent — a 1-for-80 split effective August 10, 2026 — is the second in just six months, following a 1-for-150 split in February 2026. Each prior split was followed within months by renewed share-count expansion of several hundred percent, and the instruments powering the next expansion are already in place.
The Float Picture
Post-split shares outstanding sit at approximately 32.2 million. The company states that 100% of its Class A ordinary shares are held by non-affiliates, meaning the entire outstanding count is the tradeable float. Corporate control is retained through just four Class B super-voting shares — each carrying 50 votes — held by a single entity, Feng Zhou Management Limited. There is no insider block absorbing supply and no lockup cliff ahead. Every newly issued share is immediately sellable.
Three Live Dilution Channels
Death-spiral prepaid purchase. A $31.5 million Pre-Paid Purchase agreement with Smart Mart Limited, a Hong Kong single-owner entity, converts at the lower of 50% of the signing-date closing price or 50% of the lowest close over the trailing 180 trading days — meaning every new price low for the next nine months permanently ratchets the conversion price downward for the entire remaining balance. The nominal post-split floor of $16.00 is already roughly 4.5 times above the current market price, strongly suggesting the floor has been reset or waived. A resale registration covering 1,968,750 post-split shares — roughly 6% of the current float — is pending effectiveness. Smart Mart held zero shares as of June 30, 2026. Its entire registered block is net-new supply.
Zero-price warrants. The July 23, 2026 offering included 56,250 post-split Ordinary Warrants carrying a "zero price exercise" feature: a formula that delivers shares based on the gap between the exercise price and the lowest volume-weighted average price over the prior ten trading days, divided by half that low price. At maximum, each warrant multiplies into roughly 14 shares. That cap is active today. The result: up to 787,500 post-split shares issued to the holder for which the company receives no cash at all.
A precedent makes the risk concrete. In May 2026, 3,500,000 warrants from a separate private placement were cashless-exercised into 31,500,000 shares — a realized 9-to-1 ratio on nominal 1-to-1 coverage. That single exercise produced nearly as many shares as the entire post-split float today.
Undrawn ATM. A $100 million at-the-market facility — a program allowing the company to sell shares directly into the open market on any trading day without a separate filing — with Univest Securities remains fully undrawn. That capacity equals roughly 85% of the company's entire market capitalization. At current levels, full utilization would require issuing approximately 27.9 million shares, nearly doubling the 32.2-million-share float. ATM sales require no per-transaction public disclosure; they appear only in quarterly reports.
Shelf Overhead
Behind all three instruments sits an F-3 shelf registration — a pre-filed SEC registration statement that lets a company issue securities quickly through individual "takedowns" — carrying roughly $580 million of remaining capacity, approximately five times the current market cap. The company has confirmed it is not currently subject to the baby-shelf limitation that would cap annual issuance at one-third of public float.
Structural Grade
ShareStructure assigns SXTC a dilution risk score of 10 out of 10 — Extreme. Every component is at or near the maximum: variable-rate convertible exposure, warrant overhang, recent issuance velocity, and a historical reverse-split pattern that has repeated without interruption for five years. A single placement agent, Univest Securities, sits across all three active dilution channels simultaneously — the ATM, the zero-price-warrant offering, and the Smart Mart prepaid purchase — allowing supply to be sequenced continuously without new counterparty friction.
