MD&A
Text added vs the prior filing · source: 10-Q · 2026-07-30
For the three and six months ended June 30, 2026, our test report volume increased by 16% and 13%, respectively, compared to the same periods in 2025. The increase primarily reflects continued growth in our core revenue drivers, TissueCypher and DecisionDx-Melanoma. TissueCypher test report volume i…
Income tax expense consists primarily of income taxes related to federal and state jurisdictions in which we conduct business. We maintain a full valuation allowance for deferred tax assets including operating loss carryforwards and R&D credits and other tax credits.
The $25.0 million increase in net revenues from our non-dermatologic tests was primarily attributable to higher test report volumes for our TissueCypher Barrett’s Esophagus test and, to a lesser extent, a higher realized average selling price (“ASP”). The increases in our TissueCypher Barrett’s Esop…
The $7.6 million decrease in net revenues for our dermatologic tests was primarily attributable to our DecisionDx-SCC test, driven by lower realized ASP and lower test report volumes. The reduction in ASP was primarily driven by the loss of Medicare LCD coverage in April 2025.
Our gross margin percentage was 74.9% for the three months ended June 30, 2026, compared to 77.3% for the same period in 2025. The decrease primarily reflects higher expenses for lab supplies, higher personnel costs and higher lab services costs reflecting the shift in the mix of reports issued part…

IDgenetix is a PGx test that guides personalized mental health medication selection and management for patients with depression, anxiety and other mental health conditions. After careful further assessments, we discontinued our IDgenetix test in May 2025.
IDgenetix is currently covered under a Noridian LCD policy and accompanying billing and coding article developed by MolDX. During 2023, we obtained a test-specific PLA CPT code for IDgenetix which became effective October 1, 2023. The CLFS rate of $1,336 per test was effective January 1, 2024. Our r…
For the three months ended March 31, 2026, our test report volume increased by 10% compared to the same period in 2025. Our dermatologic test report volume increased by 6% for the three months ended March 31, 2026 compared to the prior period in 2025, largely driven by continued growth from our Deci…
On July 4, 2025, the One Big Beautiful Bill Act (“OBBBA”) was enacted into law. The OBBBA includes a broad range of tax reform provisions affecting businesses, including reinstatement of permanent expensing of domestic research and development costs, higher EBITDA cap on the deduction for interest e…
Income tax expense consists primarily of income taxes related to federal and state jurisdictions in which we conduct business. Income tax benefit is primarily due to the revised estimated useful life of our intangible asset related to the discontinuation of our IDgenetix test offering in May 2025, w…

How to read Risk Factors (Item 1A) in a 10-Q
A 10-Q risk-factor section usually takes one of three forms; this page classifies it as one of:
- Pointer — the filer states there have been no material changes and points back to the annual 10-K risk factors; there is no own risk text to compare this quarter.
- Partial update — the filer carves out specific updated risks ("except as set forth below"); the excerpts show exactly what is new this quarter.
- Restated in full — the quarter carries the complete risk-factor text. When the prior quarter was only a pointer there is no prior full text to diff against, so the page flags the section as restated instead.
This describes the filing structure only — it is never a judgement on whether risk went up or down.
