TGTX -- Earnings Review Q4 FY25 (Atlas)

Date: 2026-04-03 Quarter: Q4 FY25 (Dec 2025) Market cap: ~$5.3B | EV/TTM Rev: 8.8x | Revenue growth: +78% YoY (Q4), +87% FY25

Verdict

Q4 FY25 was the strongest quarter in TGTX's history -- $192.6M revenue (+78% YoY, +19.1% QoQ), $50.5M operating income (26.2% margin), record new patient enrollments, and QoQ re-acceleration that broke a three-quarter deceleration trend. The beat-and-raise pattern continues: FY25 landed $616M vs initial $565M guide. FY26 guidance of $888M midpoint implies 44% growth, likely conservative given the 8-10% historical beat rate. Gross margin compression to 80.2% (8 consecutive quarters of decline) is the only blemish, but op margin expansion to 20% FY25 demonstrates operating leverage offsetting the COGS headwind. Post-quarter, the $750M Blue Owl refinancing and $300M buyback authorization signal management conviction. Conviction: 3.5/5 -- unchanged from stock analysis. Execution is excellent; single-product concentration remains the structural cap.

Six-Factor Score

Factor Rating Detail
Growth Strong +87% FY25 YoY, +78% Q4 YoY. Absolute dollar adds accelerating: +30.9MQoQinQ4vs+20.6M in Q3, +$20.2M in Q2. FY26 guided +44%
Trajectory Flat YoY % decelerating (92% to 78% to 44% guided) per law of large numbers. But QoQ re-accelerated (+14.6% to +19.1%), and incremental revenue dollars expanding. Organic deceleration, not demand deterioration
Margins Mid Gross 80.2% compressing (91.5% at launch peak to 80.2% now -- 11.3pp in 8Q). Op margin expanding: 12.7% FY24 to 20.0% FY25. SG&A leverage offsetting GM compression. $100M SC manufacturing in FY26 is a near-term GM headwind
Dominance Contested Third-place in anti-CD20 behind Ocrevus (7.6B)andKesimpta(3B+). Differentiated on infusion time (~1hr vs 3.5hr) and cost ($59K vs $71K). Fenebrutinib (oral BTK) hit all 3 Phase III endpoints -- structural threat 2-3 years from market
Valuation Fair EV/TTM Rev 8.8x, EV/FY26 Rev 6.1x. Rule-of-X = 44% + 20% = 64. For 44% guided growth + 20% margins, 6x forward is reasonable. Not cheap, not rich
Special Present (1) SC BRIUMVI Phase III 75% enrolled, data YE2026 -- could double TAM. (2) Azer-cel in progressive MS -- zero approved therapies. (3) Founder 21% ($1B+). (4) $750M Blue Owl credit + $300M buyback (March 2026). (5) Consistent 8-10% beat vs initial guide

BRIUMVI US $170-180M $182.7M Beat -- +$29.8M QoQ (+19.5%) from Q3

Capital Actions Buybacks continue $750M refi + $300M buyback auth (post-Q) Positive surprise -- management backed rhetoric with action

Delta Assessment

Three things surprised me:

  1. The QoQ re-acceleration (+19.1%) was more emphatic than expected. After three quarters of sequential deceleration (Q4 FY24 +29% -> Q1 FY25 +12% -> Q2 +17% -> Q3 +15%), Q4 jumped to +19%. More importantly, incremental revenue dollar adds expanded: $12.7M, $20.2M, $20.6M, $30.9M. The launch curve is steepening, not flattening. This is the single most bullish data point in the quarter.

  2. Gross margin compression hit 80.2% -- below my 81% floor. Eight consecutive quarters of decline from 91.5%. COGS up 162% YoY vs revenue +87% means manufacturing costs are scaling faster than revenue. The $100M incremental SC manufacturing investment in FY26 means this likely gets worse before it gets better. I now expect GM to trough at 76-78% in 2026 before recovering in 2027 post-buildout.

  3. Post-quarter capital actions were more aggressive than expected. The $750M Blue Owl refinancing (replacing 250M, net+500M) and tripling the buyback authorization to $300M is a strong signal. Management said "we will not hesitate to add leverage" on the call, and three weeks later they did exactly that. The ~$38M repurchased at $28.98 avg (below current $33.53) was well-timed. This converts a vague commitment into a trackable position.

Leading Indicators

TGTX does not report RPO, NRR, ARR, or customer-count metrics. Available biotech leading indicators:

Indicator Signal Assessment
New patient enrollments "Record" in Q4 (qualitative) Bullish -- demand accelerating into year 3 of launch
QoQ revenue acceleration +14.6% (Q3) to +19.1% (Q4) Bullish -- broke 3-quarter deceleration trend
Incremental revenue dollars $20.6M (Q3) to $30.9M (Q4) -- all-time high Bullish -- curve steepening
Q1 FY26 guidance $190-200M total vs Q4 actual $192.6M Neutral -- Q1 seasonally soft; management guides conservatively
FY26 guidance cadence 888Mmidpoint; H2implied 230M+/quarter Bullish -- continued ramp
Ex-US revenue $6.4M Q4 (first data point) Early -- de minimis but establishes international revenue base
ENABLE real-world data 99.5% relapse-free across 401 patients Bullish -- real-world confirms pivotal trial efficacy

No bearish divergence detected. All available indicators point in the same direction.

Biopharma Peer Context

Company EV/NTM Rev Rev Growth Op Margin Profile
TGTX ~6x +44% 20% Single product, MS, commercial ramp
ARGX ~12x +50% Negative Single product (Vyvgart), MG
SRPT ~8x +30% Improving Rare disease, gene therapy
VRTX ~12x +12% +45% Multi-product, CF + pain
HALO ~10x +20% +50% Royalty-driven, mature

TGTX trades at a discount to commercial-stage biopharma peers growing >30%. The discount reflects single-product concentration and fenebrutinib. If SC BRIUMVI succeeds and diversifies the revenue base, re-rating toward 10-12x forward revenue ($56-69/share) is a realistic 18-24 month scenario.

Platform & Secular Position

Secular trend: High-efficacy MS therapy adoption. MS therapeutics market ~28B(2024)growingto 39B by 2030 (CAGR ~6%). Anti-CD20 class gaining share from older platform therapies.

Platform status: Currently a point solution -- one drug, one indication, one formulation. The 2026-2028 roadmap builds toward platform: SC BRIUMVI (2028 launch), indication expansion (MG, lupus, autoimmune), azer-cel (CAR-T for progressive MS), and combination approaches. If 2-3 succeed, TGTX transitions to multi-product platform. Today, it is not there.

TAM penetration: BRIUMVI FY25 US revenue (594M)is 610B anti-CD20 infusion market. With SC formulation, addressable segment expands to ~$13-14B. Peak BRIUMVI estimates range $2-4B. Barely penetrated.

Key Risks

  1. Single-product concentration. BRIUMVI is 96% of FY25 revenue. Any safety signal, manufacturing disruption, or formulary exclusion hits the entire company with no backup.
  2. Fenebrutinib oral disruption. Roche's oral BTK inhibitor hit all 3 Phase III endpoints in MS. If approved 2028-2029, an oral pill matching infusion-class efficacy structurally shrinks the anti-CD20 infusion market. FDA filing expected 2026-2027; not yet confirmed.
  3. Gross margin compression. Eight consecutive quarters of declining GM (91.5% to 80.2%). The $100M SC manufacturing investment in FY26 will pressure further -- GM likely troughs at 76-78% before recovering 2027.
  4. Leverage accumulation. 750Mgrossdebtpost − refinancing(SOFR + 4.7571M annual interest = 12% of FY25 revenue. Additional $250M accordion available. Manageable at current growth rates but creates financial risk if growth slows.
  5. Cultural/governance risk. Glassdoor 2.2/5, dual chairman/CEO role, founder power concentration. For a 399-person sales-execution-dependent company, cultural dysfunction can directly impair commercial execution.

Key Catalysts

  1. ENHANCE topline data (mid-2026). Positive data simplifies dosing to a single 600mg infusion, potentially accelerating adoption.
  2. Subcutaneous BRIUMVI pivotal data (YE2026 / Q1 2027). The single most important catalyst. Success doubles TAM and directly competes with Kesimpta's $3B+ franchise.
  3. Azer-cel Phase 1 data in progressive MS (H2 2026). High-risk, high-reward in a disease with zero approved therapies.
  4. Q1 FY26 results (May 2026). Tests whether $190-200M guide continues the 8-10% beat pattern. A beat to $205-210M would confirm the launch curve is steepening.
  5. Buyback execution. ~$262M remaining of 300Mauthorization.At 33/share, that is ~7.9M shares or ~5% of float. Accretive if deployed aggressively in next 12 months.
