TG Therapeutics (NASDAQ:TGTX) falls as BRIUMVI revenue increase outweighed by rising costs

NEW YORK, August 3, 2026, 10:22 EDT

  • TG stock fell 9.8% to $46.94 as of 10:06 a.m. EDT. The iShares Nasdaq Biotechnology ETF (NASDAQ:IBB) slipped 0.2%.
  • Revenue for the second quarter increased by 70% to $240.3 million, while operating income declined 38% to $21.7 million and diluted earnings per share fell to five cents.

TG Therapeutics Inc shares fell in early trading in New York on Monday, as stronger BRIUMVI sales did not offset a significant earnings shortfall and broader spending outlook. Evercore ISI analyst Michael DiFiore noted that analysts were “underestimating operating expenses.” Investor’s Business Daily

The results were mixed. Revenue exceeded the analyst consensus of $229.7 million by 4.6%. Diluted EPS came in 84% under the 31.71-cent forecast. Demand outperformed expectations, but costs were higher.

TG’s revenue grew by $99.2 million compared to a year earlier, while costs and expenses increased by $112.4 million. Each additional $1 in revenue resulted in $1.13 in extra cost. R&D spending almost tripled, SG&A climbed by 48%, and operating margin dropped to 9.0% from 24.7%, based on company data calculations.

Management stated that manufacturing activity made reported profit an unreliable indicator of the current operating pace. Chief Executive Michael Weiss said, “BRIUMVI is enabling us to build something much bigger.” Finance chief Sean Power noted net income would have totaled roughly $62 million had it not been for manufacturing charges, connecting that number to the company’s “underlying earnings power.” On the same call, base 2026 R&D and SG&A was projected at $350 million to $400 million, up from around $350 million in May, while global revenue guidance increased to about $950 million from $925 million. With the revised midpoint, base spending increases by $25 million, matching the rise in revenue. At the second quarter gross margin of 82.9%, the sales gain would contribute about $20.7 million in gross profit if the margin remains steady. Investing.com

U.S. sales remain the primary driver for second-quarter results that topped expectations. In May, TG targeted $220 million in second-quarter sales after first-quarter sales of $194.8 million, requiring $470.2 million to $485.2 million in sales for the second half. First-half sales came to $422.5 million. The updated range lowers the second-half requirement to $467.5 million-$482.5 million, reducing the target at both ends by $2.7 million. To hit the new range, average third- and fourth-quarter sales only need to be 2.7% to 6.0% higher than second-quarter sales. TG recorded $58.8 million of its $100 million planned special manufacturing spend in the first half, leaving about $41.2 million if the full-year target remains intact.

First-half base used$414.8 mln: Q1 actual, Q2 goal$422.5 mln actual

Average per second-half quarter$235.1–$242.6 mln$233.8–$241.3 mln

Management aims for quarterly U.S. revenue to exceed $250 million before the end of the year. Achieving this would mean a significant portion of the growth needed in the second half would be concentrated in the fourth quarter; a weaker third quarter would still be consistent with the updated outlook. However, if core spending lands at the higher end of projections, the stock might not respond positively.

The next significant update is for subcutaneous BRIUMVI. Phase 1 results showed mean bioavailability above 60%, and company projections indicate quarterly dosing is feasible. Enrollment for the Phase 3 trial is complete, with top-line results expected late in 2026 or early 2027.

Risks: Core operating costs may rise to $400 million, surpassing the May goal by $50 million. Phase 3 outcomes or schedule could fall short. BRIUMVI remains TG’s sole commercialized drug, so any drop in demand would affect total commercial revenue.

Further analysis

Is TG capable of achieving the increased 2026 BRIUMVI sales objective?
BRIUMVI sales in the United States hit $227.7 million, representing a 64% increase from the prior year. For the first half, sales totaled $422.5 million. TG Therapeutics (TGTX.O) now forecasts full-year revenue between $890 million and $905 million. To reach this range, second-half sales would need to be $467.5 million to $482.5 million, or $233.8 million to $241.3 million per quarter—3% to 6% higher than Q2. Management projects Q4 sales over $250 million, with Q3 expected to be seasonally stable. TG Therapeutics
What caused shares to decline even with increased revenue guidance?
At 9:54 a.m. ET, shares of TGTX were at $47.46, down 8.8%. Second-quarter revenue gained 70% to $240.3 million. Diluted EPS declined to $0.05 from $0.17, while analysts polled by FactSet expected $0.31. Research and development costs totaled $95.3 million, with $54.6 million attributed to manufacturing expenses. Operating income decreased 38% to $21.7 million. TG Therapeutics
To what extent does the raised guidance account for ongoing U.S. demand?
Global guidance increased by $25 million, moving from roughly $925 million to $950 million. The U.S. forecast changed by $5 million, now at $890–905 million. According to management, some second-half revenue outside the U.S. will be driven by milestones and partner payments, which are less regular than product sales. As a result, the overall increase is wider than just core U.S. demand. TG Therapeutics
Is there still significant potential for upside based on the current valuation?
TG traded at $47.46, placing its market capitalization at $7.59 billion, approximately eight times its guidance. FactSet projects 2026 EPS at $1.29, equivalent to about 37 times earnings. For 2027, FactSet sees EPS at $3.05, or roughly 16 times earnings. The FactSet summary continued to list its pre-earnings $0.31 estimate for Q2, so updates could be forthcoming. FactSet's price target of $68.43 suggests 44% potential upside, while MarketBeat's $58.50 target indicates a 23% gain. Both targets may not reflect the latest report. The Wall Street Journal
Which catalyst and primary downside risk are currently most significant?
Phase 3 results for subcutaneous BRIUMVI are due by the end of 2026 or in the first quarter of 2027. Phase 1 findings indicated quarterly dosing is feasible and showed bioavailability exceeding 60%. TG management estimates that self-administered therapies account for 35–40% of the active anti-CD20 market. A positive outcome would enable TG to capture this market share. If the program fails or is delayed, the market concentration remains unchanged. Every revenue stream disclosed for the second quarter was tied to BRIUMVI. TG Therapeutics
