Tessera Defense and Homeland Security Inc. (HLSQ) files reports with the U.S. Securities and Exchange Commission as a NYSE American-listed issuer. These SEC filings document both the company’s current activities as a physical security technology platform and its earlier history as BiomX Inc., a biotechnology business that reported under the PHGE ticker. The registrant’s CIK remains 0001739174 throughout this transition.
Annual reports on Form 10-K and quarterly reports on Form 10-Q provide detail on Tessera’s business description, risk factors, and financial statements. Each report should be read in the context of its reporting period and the business described at that time. Readers should note which periods describe BiomX’s biotechnology operations and which describe Tessera’s security-technology focus.
Current reports on Form 8-K are especially important for understanding key corporate events. An 8-K filed in connection with the September 11, 2026 name and ticker change explains that BiomX Inc. changed its legal name to Tessera Defense and Homeland Security Inc. and that its NYSE American listing transitioned from PHGE to HLSQ. That filing clarifies that the change did not create a new registrant but rebranded the existing company and reflects its shift toward physical security technology.
Other SEC filings, such as registration statements or proxy materials, can provide additional information on capital structure, corporate actions and governance. Historical filings under the BiomX name and PHGE ticker remain part of Tessera’s regulatory record and may be relevant for long-term financial analysis, and subsequent HLSQ filings can be read alongside this retained history to follow the security business.
BiomX Inc. entered into an amendment to a previously issued warrant covering up to 3,300,000 shares of common stock that were issued with 3,300 shares of Series Y Convertible Preferred Stock sold in December 2025. The amendment shortens the warrant’s term so it now expires on December 31, 2026, reduces the exercise price from $2.00 to $1.00 per share, and changes the cashless exercise formula to reference the lowest VWAP over the five trading days before exercise notice. The number of underlying warrant shares remains unchanged. In a CEO letter, BiomX describes this as part of a broader financial and strategic reset aimed at simplifying its capital structure, resolving long-dated warrant overhang, cutting costs including closing a Maryland facility, and exploring a pivot toward sectors such as advanced technologies and defense-related applications.
BiomX Inc. director and 10% owner Yeganeh Reuven, through Pyu Pyu Capital LLC, converted Series Y Convertible Preferred Stock into Common Stock at a conversion price of $2.00 per share and then sold the resulting shares in private transactions.

The filing notes the securities are directly owned by Pyu Pyu Capital LLC and may be deemed beneficially owned by Reuven as its sole member, with Reuven disclaiming beneficial ownership except to the extent of his pecuniary interest.

BiomX Inc. is a clinical-stage company developing bacteriophage therapies targeting harmful bacteria in chronic conditions such as diabetic foot infections and osteomyelitis. The company has no approved products and has never generated revenue from product sales.
In December 2025 BiomX discontinued development of its cystic fibrosis candidate BX004 after adverse events and resource constraints, and later began insolvency proceedings for its Israeli subsidiary BiomX Ltd., which previously housed core operations. A court-appointed trustee now controls that subsidiary, and BiomX no longer treats it as an asset.
To address severe liquidity pressure, BiomX entered a Securities Purchase Agreement for 3,300 shares of Series Y Convertible Preferred Stock and warrants, for $3.0 million in gross proceeds. If stockholders approve the deal, the investor is expected to become the majority common stockholder and could change the company’s business, strategy and objectives. The company’s risk factors highlight substantial doubt about its ability to continue as a going concern and emphasize that its future depends heavily on securing this stockholder approval and further financing.
Alyeska Investment Group and related reporting persons filed an amended Schedule 13G showing beneficial ownership of 38,176 shares of BiomX Inc. common stock, representing 2.5% of the class. This amount includes 1 share of common stock and warrants to purchase 38,175 additional shares.
The ownership percentage is based on 1,526,640 BiomX common shares outstanding, after a 19:1 reverse stock split reported in a prior Form 8-K. The filers certify the position is held in the ordinary course of business and not for changing or influencing control of BiomX.
