Rigel Pharmaceuticals, Inc. (RIGL) is a South San Francisco-based biotechnology company developing and commercializing therapies for hematologic disorders and cancer, with a portfolio that includes TAVALISSE, REZLIDHIA, GAVRETO, and the newly launched VEPPANU. Shares of RIGL fell sharply in Wednesday's session, dropping 12.67% to $39.92 from the prior close of $45.71. The decline extended losses that began after the company reported third-quarter 2026 results, as investors focused on an earnings miss and slowing momentum in the legacy product portfolio despite better-than-expected revenue.
The immediate market reaction centered on the bottom line. Rigel posted third-quarter diluted earnings per share of $0.65, well below the consensus estimate near $0.87 and down 55.5% from the year-ago period. While total revenue of $80.89 million beat expectations of roughly $78 million and grew 16.5% year over year, the earnings shortfall reflected a sharp rise in costs. Total costs and expenses climbed to $63.8 million from $41.0 million a year earlier, as research and development spending more than doubled to $18.3 million and selling, general, and administrative expenses rose to $34.7 million to support the VEPPANU commercial launch. The combination of higher spending and compressed margins overshadowed the record top-line result, prompting investors to sell the stock.
Beneath the headline numbers, the composition of growth added to the bearish tone. Net product sales reached a record $72.3 million, up 13% year over year, but the underlying drivers diverged. TAVALISSE, the company's foundational product, grew just 3% to $46.0 million, a marked deceleration from 18% growth in the second quarter and a sequential decline despite what management described as record demand. GAVRETO sales fell 11% to $9.8 million, while REZLIDHIA was a relative bright spot, rising 20% to $9.9 million. The slowdown in the mature portfolio raises questions about how quickly the base business can fund the company's shift toward its newer growth engines.
VEPPANU, the first FDA-approved PROTAC therapy for ER-positive, HER2-negative ESR1-mutated metastatic breast cancer, generated $6.6 million in net product sales over roughly six weeks of availability — a strong early signal with more than 100 patients and clinics shipped and encouraging refill rates. However, management tempered near-term visibility by trimming 2026 net product sales guidance, excluding VEPPANU, to $255–260 million from $255–265 million, while narrowing total revenue guidance upward to $290–295 million on higher expected contract revenue. The company also indicated it would not guide VEPPANU until 2027 and would stop disclosing detailed launch metrics, making the next several quarters harder to underwrite. Cash and short-term investments fell to $99.3 million from $155.0 million, adding a layer of balance-sheet scrutiny.
Trading in RIGL was notably heavy around the earnings release, with volume running well above the stock's recent daily average as the report and subsequent conference call circulated. The decline was largely idiosyncratic, driven by company-specific fundamentals rather than a broad rotation out of the biotechnology sector. The stock's slide pushed it decisively below the $45 area, which had acted as a near-term support zone following the prior session's drop, and reinforced a negative technical tone heading into the second half of the week.
Investors will now focus on execution of the VEPPANU launch and whether the early demand trajectory translates into durable prescription growth into 2027. A key near-term catalyst is the American Society of Hematology (ASH) meeting in December, where Rigel plans to present updated Phase 1b data, including preliminary efficacy results, for its R289 dual IRAK1/4 inhibitor in lower-risk myelodysplastic syndromes. The company remains on track to select a recommended Phase 2 dose by the end of 2026 and expects to initiate a registrational program next year. Risks include continued deceleration in TAVALISSE, potential gross-to-net and inventory variability in product sales, and the inherent uncertainty of clinical development. Management has reiterated its expectation for positive net income for full-year 2026, but the path to restoring investor confidence will likely depend on demonstrating that the launch investments are producing scalable returns.
