Organovo's Bioprinting More Than A 'Stupid Exercise'

Summary

Misleading short pieces and a cooling sector have had a negative effect on Organovo's share price.

Organovo's fully cellular bioprinting method provides crucial benefits over competing approaches. This will distinguish Organovo as a 3D bioprinting leader.

Data that the company has released has been compelling enough to warrant contracts without third-party validation and product launch.

Avoid Stratasys For Now

Summary

Stratasys shares are trading lower as the company did not raise full year guidance despite a first quarter revenue beat.

While revenue and gross margins were strong, earnings were only in-line as the company spent aggressively on R&D and SG&A.

Revenue growth will slow over the balance of the year amid stiffening competition and tougher comparisons, which makes the current 40x multiple excessive.

While I prefer SSYS to other 3-D printer stock, I would be a seller until shares fall into the $60's when the multiple is more appealing.

Organovo Reports Fiscal 2014 Financial Results

ATP back above $4.

Roche (RHHBY -0.7%) Innovation Center Basel's Dr. Adrian Roth presented results from a collaborative study with Organovo (ONVO +9.1%) scientists using the company's 3D Human Liver Tissues at the 3D Cell Culture 2014 conference in Freiburg, Germany yesterday. The study, conducted at Organovo, showed that the 3D Liver Model was able to distinguish a hepatotoxic drug from a close non-toxic chemical analog. The model detected the toxicity at physiologically relevant doses.

Organovo plans to launch the 3D Human Liver Tissue in late Q4 2014 as a testing service performed at Organovo's laboratory. This is a change in strategy considering it originally stated that it would sell the "assay" or "model" on-line as a deliverable product. The name change and service-only offering implies that the product is not as fully-developed as planned.

ONVO +8.5%.
