Why Is TG Therapeutics (TGTX) Stock Down -11.15% Today?
Key Takeaways
- TG Therapeutics shares plunged 11.15% during Monday's trading session, falling from a prior close of $52.03 to $46.23, following the release of second-quarter 2026 earnings.
- The primary catalyst was a severe earnings-per-share miss: the company reported EPS of $0.05, dramatically below the consensus analyst estimate of approximately $0.31.
- Revenue beat expectations: total global revenue reached $240.3 million, up 70.3% year-over-year and above Wall Street forecasts of roughly $231 million.
- R&D spending tripled to $95.3 million from $31.8 million a year ago, driven by manufacturing investments for subcutaneous BRIUMVI and an expanding clinical pipeline.
- Full-year guidance was raised: the company lifted its 2026 total global revenue target to approximately $950 million, with BRIUMVI U.S. net product revenue now expected at $890–$905 million.
- Traders are watching upcoming pipeline catalysts including Phase 3 subcutaneous BRIUMVI data expected by early 2027 and Phase 1 azer-cel data in progressive MS later this year.
Opening Summary
TGTX, the commercial-stage biopharmaceutical company behind the multiple sclerosis drug BRIUMVI (ublituximab-xiiy), saw its stock tumble 11.15% on Monday. Shares dropped to $46.23 from Friday's closing price of $52.03, making it the steepest single-day decline for the company since early January 2026. The sell-off was triggered by TG Therapeutics' second-quarter 2026 earnings report, which revealed a dramatic EPS shortfall despite strong top-line growth and an upward revision to full-year revenue guidance.
Q2 Earnings Miss Overshadows Revenue Beat
TG Therapeutics reported second-quarter 2026 earnings of just $0.05 per share, missing the consensus analyst estimate of roughly $0.31 by a wide margin and falling well below the $0.17 per share recorded in the same quarter a year earlier. The bottom-line compression was particularly jarring to investors given that the company's revenue performance was robust. Total global revenue came in at $240.3 million, a 70.3% surge year-over-year that exceeded Wall Street expectations of approximately $231 million.
BRIUMVI, the company's anti-CD20 monoclonal antibody approved for relapsing forms of multiple sclerosis, continued its strong commercial trajectory. U.S. net product revenue for the drug reached $227.7 million, up 64% from the prior-year period and surpassing management's guided range of $220 million. Ex-U.S. sales to licensing partner Neuraxpharm contributed an additional $8.1 million.
The disconnect between top-line strength and bottom-line weakness stems entirely from a sharp escalation in operating expenses. Research and development spending more than tripled to $95.3 million from $31.8 million a year ago, with approximately $54.6 million of that tied directly to subcutaneous BRIUMVI manufacturing and secondary-manufacturer start-up costs. Selling, general, and administrative expenses also climbed to $82.1 million from $55.6 million, reflecting increased marketing spend and personnel costs supporting BRIUMVI's commercialization.
Raised Guidance and Pipeline Ambition
In a move that might normally support a stock, TG Therapeutics raised its full-year 2026 total global revenue target to approximately $950 million, up from its prior outlook of around $925 million. The company also lifted its U.S. BRIUMVI net product revenue guidance to $890–$905 million. CEO Michael Weiss emphasized that BRIUMVI is "on track to exit 2026 at an approximately $1 billion annualized U.S. revenue run rate."
However, the company also flagged that full-year operating expenses — including R&D and SG&A — are now expected to reach approximately $350–$400 million excluding non-cash compensation, plus an additional $100 million in subcutaneous manufacturing and secondary-supplier start-up costs. The substantial spending ramp is tied to an ambitious pipeline expansion that includes a subcutaneous formulation of BRIUMVI in Phase 3 trials, a Phase 3 ENHANCE study supporting a simplified single-infusion initiation regimen, and new clinical programs in myasthenia gravis and treatment-resistant schizophrenia. While these investments could meaningfully expand BRIUMVI's addressable market over the long term, they are punishing near-term profitability — and the market reacted accordingly.
Market Context and Trading Activity
Monday's sell-off reflected more than just an earnings disappointment. TGTX had rallied approximately 74.6% year-to-date coming into the session, significantly outperforming the broader biotech sector. With shares trading near the upper end of their 52-week range and a 50-day moving average of roughly $50.48 well below Friday's close, the stock was vulnerable to profit-taking on any perceived misstep. Today's decline pushed the stock decisively below its 50-day moving average, a technical level closely watched by traders.
Volume was elevated relative to recent sessions, signaling strong conviction behind the move. The broader market offered little shelter: while the biotech sector has generally outperformed this year, investor sentiment soured on high-multiple growth names that failed to deliver on the bottom line. The negative reaction echoed similar moves in peer biotech stocks reporting mixed second-quarter results, underscoring a market environment increasingly focused on profitability over pure revenue momentum.
What Comes Next for TGTX
Looking ahead, TGTX faces a critical period of execution. The company expects to present full Phase 3 ENHANCE trial results later this year, which could support regulatory submission for a simplified BRIUMVI initiation schedule by mid-2027. Top-line data from the pivotal Phase 3 trial of subcutaneous BRIUMVI is anticipated around year-end 2026 or early 2027 — a potentially transformative catalyst that would allow the company to compete in the self-administered segment of the anti-CD20 market, which management estimates represents 35–40% of the total opportunity.
Preliminary Phase 1 data for azer-cel, the company's allogeneic CD19 CAR T-cell therapy in progressive multiple sclerosis, is also expected in the second half of 2026. With $612.3 million in cash and investments as of June 30 and a growing revenue base, TG Therapeutics has the financial runway to fund its pipeline — but investors will closely scrutinize whether the elevated spending translates into tangible clinical and regulatory progress. Risks include potential delays in clinical timelines, payer and rebate pressures on BRIUMVI pricing, and intensifying competition in the MS space from established players like Roche's Ocrevus and Novartis' Kesimpta.
