Semper Paratus's portfolio hinges on two high-growth Stars-TVGN‑489's viral immunotherapy and a next‑gen ex‑vivo T‑cell discovery platform-driving aggressive R&D spending, while high‑margin IP licensing and secured PIPE facilities act as Cash Cows that bankroll trials; deeper Question Marks in oncology and neurology demand partnerships or major capital to become future winners, and leftover SPAC‑related Dogs are being trimmed to stop bleeding resources-read on to see how management must balance risk, cash allocation, and strategic exits to turn pipeline promise into shareholder value.

Semper Paratus Acquisition Corporation (LGST) - BCG Matrix Analysis: Stars

Stars

The TVGN 489 Immunotherapy for Viral Infections segment is positioned as a Star within LGST's portfolio: high market growth and high relative market share in the niche of off-the-shelf cytotoxic T lymphocyte (CTL) therapeutics targeting COVID-19 and Long COVID. As of December 2025 the addressable viral immunotherapy market for this indication is projected to grow at a CAGR of 16.5% through 2030, with a potential U.S. Long COVID patient population exceeding 15 million. TVGN 489 carried an initial enterprise valuation of $1.2 billion at the time of the business combination and commands a dominant share in the specialized CTL off-the-shelf segment.

Key operational and financial inputs for TVGN 489 include heavy clinical R&D investment, milestone-driven earnouts, and high projected commercialization returns. Clinical R&D represents ~65% of total corporate CAPEX, reflecting prioritization of this unit. Management projects an ROI >300% upon FDA approval for the U.S. market, driven by high unmet need, premium pricing potential for cell therapies, and broad Long COVID prevalence.

Strategic implications and operational priorities for TVGN 489:

• Prioritize late-stage clinical milestones to trigger unlocks of the 20M share earnout and de-risk commercialization value.
• Maintain CAPEX allocation at or above current levels (65%) to accelerate pivotal studies and expedite FDA filing timelines.
• Develop commercial supply chain and out-licensing or partnership options to scale off-the-shelf CTL manufacturing cost-effectively.
• Price and reimbursement strategy modeling to capture premium cell therapy pricing while maximizing market penetration in a 15M+ patient pool.

The Next-Generation Ex-Vivo T-Cell Discovery Platform functions as a technology Star: participating in a broader cell therapy market valued at $5.4 billion and expanding at ~20.2% annually. The platform underpins 100% of LGST's current pipeline, reducing discovery timelines by ~25% versus traditional CAR-T approaches and increasing screening throughput by ~40% year-over-year following AI-driven enhancements. Although not yet revenue-generating, the platform represents a high-growth, high-investment asset central to sustained pipeline expansion and competitive differentiation versus larger biotech incumbents.

Priority actions and risk mitigants for the platform:

• Continue AI and automation investments to sustain throughput gains and shorten time-to-first-in-human for platform-derived assets.
• Pursue strategic collaborations or translational partnerships to monetize platform capabilities before product revenue realization.
• Invest in modular, scalable manufacturing solutions to enable rapid commercial launch for platform-derived therapeutics.
• Monitor competitive landscape and patent strategy to defend platform IP and maintain high relative share of discovery within the company.

Semper Paratus Acquisition Corporation (LGST) - BCG Matrix Analysis: Cash Cows

Cash Cows

Intellectual Property and Patent Licensing

The company's extensive portfolio of patents related to HLA-restricted T-cell technology provides a steady foundation of value despite the clinical-stage nature of the business.

The IP segment exhibits a stable market growth rate of approximately 4.5% annually for foundational biotech patents, with predictable licensing demand from cell-therapy developers and contract research organizations (CROs). Semper Paratus holds over 15 core patents covering antigen presentation, HLA restriction mapping, and off-the-shelf T-cell manufacturing processes, creating a significant barrier to entry for competitors and niche protection for partnering opportunities.

Licensing and sub-licensing discussions are forecast to produce a low-CAPEX revenue stream characterized by high operating margins. Current internal models and market comparables suggest operating margins in excess of 80% on license fee revenue, with gross yields on incremental licensing transactions ranging from 70% to 85% after amortization of IP-related legal and prosecution costs.

As of late 2025, the IP portfolio is estimated to represent approximately 45% of the company's intangible asset value on the balance sheet, equating to an estimated carrying value of $540 million given a reported intangible asset base of $1.2 billion. Ongoing maintenance and prosecution costs for the portfolio are projected at $1.2-$2.0 million annually, representing minimal reinvestment compared to revenue potential.

• Key strengths: durable revenue with minimal capex; strong bargaining leverage due to essential claims; high gross margins on licensing.
• Key dependencies: enforcement and freedom-to-operate clarity; continued relevance of HLA-restricted claims to emerging allogeneic T-cell developers.
• Risks: patent expiry timelines clustered in late-2030s could compress long-term runway; potential invalidation challenges could reduce licensing leverage.

Strategic Institutional Funding and PIPE Facilities

Management of institutional equity facilities and Private Investment in Public Equity (PIPE) serves as a critical financial 'cow' that sustains operations and funds development milestones.

Post-merger, Semper Paratus secured access to structured funding facilities in the range of $35 million to $60 million, in addition to standing PIPE commitments, designed to ensure liquidity through key clinical phases. These facilities provide capital at an economically favorable cost relative to market alternatives; modeled effective financing cost for these instruments is below 6% annualized when equity issuance and fees are amortized over expected draw schedules.

The company's use of PIPE and institutional equity has maintained a debt-to-equity ratio below 0.15 as of Q4 2025, helping preserve balance-sheet flexibility and avoid high-interest cash drain typical of small-cap biotech firms. During the pre-commercialization phase, these facilities accounted for approximately 90% of total cash inflows, underscoring the segment's dominant contribution to corporate liquidity.

Leveraging a $1.2 billion enterprise value and cash balances plus committed facilities, the company projects a cash runway extending through December 2026 under current burn assumptions (~$35-$45 million annualized net cash burn excluding milestone inflows). This runway estimate assumes staged draws from PIPE facilities and no material acceleration of trial costs.

• Advantages: low-cost liquidity relative to high-rate debt; predictable staged funding aligned to trial milestones; preserves ownership control compared to higher-interest borrowings.
• Vulnerabilities: heavy reliance on institutional investor appetite; potential equity dilution pressure if additional PIPE tranches are executed at lower prices.
• Mitigants: conservative draw schedules, milestone-based covenants, and active engagement with anchor investors to secure follow-on tranches.

Semper Paratus Acquisition Corporation (LGST) - BCG Matrix Analysis: Question Marks

Question Marks - Oncology Pipeline for Solid Tumor Therapeutics: The oncology segment targets T-cell therapies for solid tumors, a high-growth market where LGST currently holds negligible relative market share. The global oncology cell therapy market is estimated at >$10.0 billion (current year) with a projected CAGR of ~22% as efforts expand beyond hematologic malignancies. LGST's candidates are in early-stage development (preclinical/Phase I), and the company allocates ~20% of total R&D spend to this program. Projected future trial costs are estimated at $150 million to reach pivotal studies; current CAPEX already committed to the program comprises advanced manufacturing investments and GMP facilities.

Probability of technical/clinical success at Phase I for oncology therapeutics is industry-standard at ~5-10%; LGST's internal modeling uses a conservative 7% PoS to model expected value. Target indications include HPV-related cancers (cervical, oropharyngeal), representing >40,000 new U.S. patients annually and materially larger global incidence when including high-burden regions. Because of high market growth but low relative share, this unit classifies as a 'Question Mark' in the BCG matrix: large market opportunity but high uncertainty and capital intensity.

Key quantitative parameters for the oncology program are summarized below.

Recommended strategic options and operational imperatives for the oncology Question Mark:

• Secure a strategic partnership or co-development deal with a top-10 pharma to underwrite up to $150M+ in clinical spend and provide late-stage development/commercial expertise.
• Prioritize indication selection toward high-incidence, high-unmet-need tumor types (e.g., HPV-driven cancers) with clear biomarker-defined populations to accelerate enrollment and market access.
• Stage-gate additional CAPEX; defer noncritical manufacturing expansions until partner commitment or successful Phase I readout to preserve liquidity.
• Implement rigorous go/no-go criteria tied to predefined early efficacy/safety endpoints to limit sunk cost given ~7% PoS.
• Assess out-licensing options for noncore assets to recoup near-term cash and concentrate resources on lead candidate(s).

Question Marks - Neurology and Multiple Sclerosis Research Unit: The neurology unit explores T-cell-based solutions for Multiple Sclerosis (MS) and other neurodegenerative disorders. The neurology/immunology space for MS is growing at an estimated CAGR of ~7.8%, but LGST's presence is currently preclinical or in very early clinical evaluation, yielding negligible market share versus incumbents.

Competition is dominated by established players (e.g., Biogen, Novartis) that together account for >70% of current MS therapeutic revenues. The unit consumes ~10% of LGST's R&D budget, primarily for specialized CAPEX (neurological imaging platforms, biomarker validation assays, and CNS-targeted manufacturing processes). ROI remains highly speculative until proof-of-concept (PoC) data, which LGST projects will not be available until post-2026 fiscal year.

Key quantitative parameters for the neurology program are summarized below.

Strategic considerations and action items for the neurology Question Mark:

• Evaluate out-licensing or partnering to monetize early-stage assets and reduce capital requirements while retaining contingent royalties or milestone payments.
• Invest selectively in biomarker programs that can de-risk clinical readouts and create attractive licensing value (targeted spend prioritization within the 10% R&D allocation).
• Form advisory boards with CNS experts and key opinion leaders to design high-probability PoC trials and accelerate endpoint selection.
• Benchmark against competitor timelines and investments to determine if in-house development can achieve differentiated positioning or if asset divestiture is preferable.
• Model financial scenarios (internal continuation vs. out-license) including NPV sensitivity to PoC success rates, expected time-to-revenue, and potential royalty structures.

Semper Paratus Acquisition Corporation (LGST) - BCG Matrix Analysis: Dogs

Dogs

The residual Legacy SPAC Shell and Administrative Operations function as a Dog in the BCG matrix: they generate 0% of current revenue, produce negative ROI after recurring costs, and offer negligible strategic upside as LGST transitions to a biotechnology-focused public company.

Key factual metrics for the Legacy SPAC Shell:

Management actions and status:

• Cost containment: administrative expenses reduced by 15% year-over-year through headcount and vendor consolidation.
• Trust management: remaining $10.4M held in trust producing minimal interest income; active monitoring for optimal liquidation timing.
• Compliance minimization: efforts underway to reduce ongoing SEC, listing, and legal obligations consistent with full operational integration into biotech.

Risks and implications for the Legacy SPAC Shell:

• Persistent overhead (estimated $600k-$1.2M annually) exceeds income from residual assets, continuing negative cash impact.
• Decline in SPAC service market (-60%) reduces potential strategic pivot or monetization avenues for the shell.
• Regulatory or litigation exposure could increase costs unexpectedly, prolonging negative ROI.

Discontinued Transportation and Logistics Search Assets

Activities related to prior transportation and logistics target screening-including due diligence on Tevva Motors and similar targets-are legacy Dog assets: zero current market share, no alignment with the company's biotech strategy, and no recoverable CAPEX.

Operational notes on discontinued search assets:

• Due diligence dossiers retained for audit and potential legal defense; no active business development in transportation/logistics.
• Legacy line items remain in historical financial statements but are immaterial to forward-looking operations.
• Final liquidation of residual contractual interests and disposition of data assets planned to complete by Q1 2026.
