ORGANOVO REPORTS Q3 2012 FINANCIAL RESULTS,

PROVIDES BUSINESS UPDATE

SAN DIEGO, CA November 16, 2012 Organovo Holdings, Inc. (OTCQX: ONVO)

( Organovo ) a three-dimensional biology company focused on delivering breakthrough 3-D bioprinting technology, has reported on its financial results for the three and nine month period ended September 30, 2012.

Third Quarter Corporate Highlights

Third quarter 2012 revenues increased by $237,300 or approximately 102% over the same period in 2011, commensurate with the Company s continued

delivery against collaborative research agreements and the initiation of research activities within the scope of a grant from the National Institutes of Health ( NIH ). Collaborative research agreement revenues contributed $141,800 or 60%

of the revenue increase while grant revenues contributed $95,500.

Cash receipts related to the reported revenues partially offset the

Company s operating expenses and strengthened our balance sheet. During the quarter the balance sheet was additionally strengthened through the receipt of approximately $1.7 million in capital from warrant and stock option exercises. The

Company had approximately $7.7 million cash on hand at the end of the quarter. While the Company reported net earnings of approximately $38.5 million for the quarter, investors should note those earnings were primarily the result of a non-cash

adjustment resulting from the change in fair value of our warrant liabilities. The warrant liability is volatile in nature and is driven primarily by changes in the price of our Common stock, absent material changes in the number of warrants

outstanding. Investors should anticipate swings in that fair value will continue to impact reported earnings and losses.

2012, Organovo announced the receipt of two issued patents. The patents consisted of the issuance in the United States of a patent to which the Company owns the exclusive license from the University of Missouri, and the issuance in the United

Kingdom of the Company s first assigned patent.

On July 9, 2012 Organovo announced the appointment of James T. Glover, former CFO

of Beckman Coulter and Anadys Pharmaceuticals, to its Board of Directors. Mr. Glover has been affirmed as an independent director by the Organovo Board of Directors, and the Company expects to recruit additional independent directors in the

future to meet the Board independence requirements of both NASDAQ and NYSE.

On July 17, 2012, Organovo announced the commencement of

operations at its new, larger facility in San Diego, California. The increased capacity will facilitate execution of planned research, product development, and commercial initiatives. The new facility has three times the laboratory space and

approximately four times the cleanroom space of our prior facility and is expected to provide adequate capacity for our immediate and near-term needs including product manufacturing. At September 30,

2012, the Company employed twenty-six full-time employees and six part-time employees, including twenty-four individuals in research and development, an increase over second quarter employment by

four full-time and two part-time employees.

Organovo has continued to execute its business plan and has grown substantially in

2012, stated Keith Murphy, chief executive officer of Organovo. As a result we are better positioned to deliver on 3D bioprinted liver, new tissue-based disease models, and future partnership opportunities. We believe all of these

efforts will continue to grow shareholder value over the long term.

For the third quarter 2012 total revenues of approximately $469,200 were $237,300 or 102% above the approximately $232,000 in revenues for the same period

in 2011. Collaborative research revenues for the third quarter of approximately $373,800 increased $141,800 or 61% over the same period of prior year revenues of approximately $232,000. Grant revenue for the three months ended September 30,

2012 of approximately $95,500 increased approximately $95,500 over the same period of prior year. No grant revenue was received in the prior year third quarter.

Operating expenses increased approximately $3,232,500 or 378% in the three months ended September 30, 2012 over the same period in 2011, from approximately $854,400 in 2011 to $4,086,900 in 2012.

Most significantly, relative to the same period in the prior year, the Company invested in infrastructure and outside services to support its transition from private ownership to a publicly owned and traded corporation. As expected in such

transition, incremental initiatives were established in investor outreach, corporate governance, and SEC financial reporting. Non-payroll related incremental public company expenses incurred in the three month period ended September 30, 2012

were approximately $308,200. There were no such expenses incurred in the same period, prior year, due to our status as a private company. . Moreover, the Company invested in building its executive, research, and development staff, and in expanding

the number of independent board directors. As a result payroll related expenses, for the three months ended September 30, 2012, increased by approximately $676,800 or 236% over the same period in 2011. Similarly, stock-based compensation

expenses increased approximately $1,277,200, fees to our non-employee board members were initiated, raising period expenses by $32,900 and we moved into a new, larger facility to accommodate our growing administrative and research staff. Facility

related expenses increased approximately of $97,500 over the same period in 2011, as a result of that move.

The approximate $42,278,500

increase in other income (expense) for the three month period ending September 30, 2012 over the same period of the prior year, was primarily related to the change in fair value of warrant liabilities for the three months ended

September 30, 2012 of approximately $42,252,400. During the Private Placement in the first quarter of 2012 we issued warrants to purchase 6,099,195 shares of our common stock to the placement agent and warrants to purchase 15,247,987 of our

common stock to investors in the Private Placement. The warrants issued to the placement agent and Private Placement investors were determined to be derivative liabilities as a result of the anti-dilution provisions in the warrant agreements that

may result in an adjustment to the warrant exercise price. We will revalue the derivative liability on each balance sheet date and will do so until the securities to which the derivatives liabilities relate are exercised or expire. The third quarter

of 2012 also included a loss on disposal of fixed assets of approximately $158,400 which occurred in relation to moving to our new facility. Other expenses for the three months ended September 30, 2011 of approximately $182,800 related

primarily to interest recorded on convertible notes payable.
