IMPLANT SCIENCES REPORTS FOURTH QUARTER AND

FISCAL 2015 FINANCIAL RESULTS

Wilmington, MA – September 28, 2015 – Implant Sciences Corporation (OTCQB:IMSC), a leading manufacturer of explosives trace detection (ETD) and drugs trace detection solutions for homeland security applications, today announced financial results for the three months and fiscal year ended June 30, 2015.  

Revenues for the three months ended June 30, 2015 increased 271.2%, to $5.7 million, from $1.5 million for the comparable prior year period.  Our net loss for the three months ended June 30, 2015 was $4.2 million as compared with a net loss of $5.7 million for the comparable prior year period, a decrease of $1.5 million.  

Revenues for the year ended June 30, 2015 increased 51.9%, to $13.0 million, from $8.6 million for the comparable prior year period.  Our net loss for the year ended June 30, 2015 was $21.5 million as compared with a net loss of $21.0 million for the comparable prior year period, an increase of $0.5 million.

Earnings before interest, taxes, depreciation and amortization, stock-based compensation, warrants issued to non-employees and common stock issued to consultants (“Adjusted EBITDA”), which is reconciled to net loss in this press release, was a loss of $944,000 in the three months ended June 30, 2015, compared to a loss of $2,939,000 in the comparable prior year period and for the year ended June 30, 2015, a loss of $9,053,000 compared to a loss of $10,048,000 in the comparable prior year period.

Dr. William McGann, CEO of Implant Sciences, commented, “During the recently concluded quarter, we began the fulfillment of the ECAC orders with initial shipments of QS-B220’s to the Netherlands and Norway, resulting in the achievement of $5.7 million in revenues for the quarter. We are pleased to report that our order backlog, at June 30, 2015, was $44,782,000, which is largely due to the receipt, on November 10, 2014, of an initial delivery order from the TSA for 1,170 QS-B220 desktop explosives trace detectors and orders received as a result of the ECAC mandate to implement passenger checkpoint and checked baggage ETD screening at airports serving more than 500,000 passengers annually, by no later than September 1, 2015. However, our backlog does not necessarily represent actual future shipments since orders, including our delivery order with the TSA, may be delayed or cancelled by our customers without financial penalty.  We believe that our revenues for fiscal year 2016 will range between $40-43 million.”

Dr. McGann, continued, “We are continuing actions taken during the recently concluded fiscal year to better align our costs with current and future geographic sources and improve efficiencies. We have taken important steps to broaden the markets we serve, increase our revenue opportunities, and improve our financial stability.”

Details for the three months and year ended June 30, 2015 follow below.

Three months Ended June 30, 2015 vs. June 30, 2014

·

Revenues for the three months ended June 30, 2015 were $5,676,000 as compared with $1,529,000 for the comparable prior year period, an increase of $4,147,000, or 271.2%. The increase in revenue is due primarily to: a 805.6% increase in the number of QS-B220 desktop units sold in the three months ended June 30, 2015, due to increased shipments to European and Latin American in the current three month period, offset partially by a 11.9% decrease in the average unit sales prices, which resulted in a 700.9% increase in QS-B220 revenues. The increased revenues achieved on our sales of the QS-B220 were partially offset by a 16.7% decrease in the number of QS-H150 handheld units sold in the three months ended June 30, 2015, compared to the prior period, due to decreased shipments to Europe and Asia, and by a

11.8% decrease in the average unit sales prices, which resulted in a 26.3% decrease in QS-H150 revenues.  Sales of parts and supplies increased 203.8% in the three months ended June 30, 2015. Sales of QS-B220 were favorably impacted in the comparable prior period due to the acceptance of the QS-B220 into the “Qualified” section of the TSA’s Air Cargo Screening Technology List and achieving ECAC’s Common Evaluation Process of Security Equipment for airport checkpoint screening of passengers and baggage.

·

Gross margin for the three months ended June 30, 2015 was $2,361,000 or 41.6% of revenues as compared with a loss of $135,000 or 8.8% of revenues for the comparable prior year period. The increase in gross margin as a percent of revenues is primarily due to increased manufacturing overhead absorption due to increased QS-B220 unit volume and the $160,000 increase in the provision for obsolete inventory in the prior period, partially offset by decreases in the average unit sell price on sales of our QS-B220 units and our QS-H150 units.

·

Research and development expense for the three months ended June 30, 2015 was $1,095,000 as compared with $1,186,000 for the comparable prior year period, a decrease of $91,000 or 7.7%. The decrease in research and development expense is due primarily to the closure of our San Diego, CA advanced technology office, which resulted in a $72,000 decrease in payroll and benefits, a $55,000 decrease in occupancy costs, a $45,000 decrease in certification testing fees which were incurred in the prior period, $41,000 decrease in engineering consulting and a $15,000 decrease in prototypes and material costs. Partially offsetting these decreases are a $100,000 increase in incentive compensation costs due to the increased employee bonuses approved by the board of directors and a $36,000 increase in travel expenses in support of the ECAC tenders.

·

Selling, general and administrative expenses for the three months ended June 30, 2015 were $3,013,000 as compared with $2,449,000 for the comparable prior year period, an increase of $564,000, or 23.0%. The increase in selling, general and administrative expenses is due primarily to an increase of $299,000 in payroll and benefits due to increased employee bonuses approved by the board of directors, a $185,000 increase in consulting expenses, due to the due to the issuance of 550,000 shares of our common stock to certain consultants, a $179,000 increase in variable selling expenses due to higher sales, a $73,000 increase in audit costs and a $65,000 increase in legal expenses. Partially offsetting these increases are a $222,000 decrease in stock-based compensation expense on non-employee warrants, a $20,000 decrease in occupancy costs due to the relocation of our corporate offices in July 2013 and the $45,000 loss on the disposal of machinery and equipment recorded in the prior year period.

·

For the three months ended June 30, 2015, other expense was $2,446,000 as compared with other expense of $1,899,000, for the comparable prior year period, an increase of $547,000. The increase is due to increased interest expense on higher borrowings under our credit facility with DMRJ and our credit facility with BAM, and, to a lesser extent, an increase in the BAM interest rate to 16% per annum from 15% per annum, effective April 1, 2015.

·

Our net loss for the three months ended June 30, 2015 was $4,193,000 as compared with a net loss of $5,669,000 for the comparable prior year period, a decrease of $1,476,000, or 26.0%. The decrease in the net loss is primarily due to increased revenues and gross margin, offset partially by increased operating expenses and an increase in interest expense.

The Years Ended June 30, 2015 vs. June 30, 2014

·

Revenues for the year ended June 30, 2015 were $12,991,000 as compared with $8,552,000 for the comparable prior year period, an increase of $4,439,000, or 51.9%.  The increase in revenue is due primarily to the 139.7% increase in the number of QS-B220 desktop units sold in the year ended June 30, 2015, due to increased shipments to European airports, due to the ECAC mandate to implement passenger checkpoint and checked baggage ETD screening at   airports serving more than 500,000 passengers annually, by no later than September 1, 2015, increased

shipments to U.S. air cargo screening facilities, increased shipments into Latin America for use in drug detection and increased shipments to agencies of the U.S. government, which resulted in a 117.8% increase in QS-B220 revenues and, to a lesser extent,  a 73.7% increase in sales of parts and supplies in the year ended June 30, 2015, as compared to the comparable prior year period. Partially offsetting these increases are a 9.6% decrease in the number of QS-H150 handheld units sold in the year ended June 30, 2015, primarily due to decreased shipments into Mexico and China in the year ended June 30, 2015, which resulted in a 14.7% decrease in QS-H150 revenues. The average unit sell prices on sales of our QS-B220 desktop units and on sales of our QS-H150 handheld units, decreased 9.1% and 5.6%, respectively, in the current fiscal period as compared to the comparable prior period. Sales of QS-B220 were favorably impacted in the current period due to the acceptance of the QS-B220 into the “Qualified” section of the TSA’s Air Cargo Screening Technology List and achieving European Civil Aviation Conference (“ECAC”) Common Evaluation Process of Security Equipment for airport checkpoint screening of passengers and baggage. Competitive market conditions are expected to continue to have a negative impact on our average unit sales prices for the foreseeable future.

·

Selling, general and administrative expenses for the year ended June 30, 2015 were $12,201,000 as compared with $11,388,000 for the comparable prior year period, an increase of $813,000, or 7.1%.

(1) Adjusted EBITDA is defined as net loss plus interest expense, net of interest income, income taxes, depreciation and amortization, stock-based compensation, change in fair value of warrants issued to non-employees and the fair value of common stock issued to consultants.  EBITDA is commonly used in the technology industry, and we present Adjusted EBITDA to enhance your understanding of our financial performance.  We use Adjusted EBITDA as an internal performance measurement and believe that it provides investors and analysts with a measure of operating results unaffected by differences in capital structures and capital investment among otherwise comparable companies and improves comparability of results of operations. Management uses this supplemental measure to evaluate performance over a period of time and to analyze underlying trends in the Company's business and to establish operational goals and forecast that are used in allocating resources.  We expect to compute our non-GAAP financial measure, using the same consistent method from quarter to quarter and year to year.            

While we believe that Adjusted EBITDA is a useful measure for investors, it is not a measurement presented in accordance with accounting principles generally accepted in the United States, or GAAP.  You should not consider Adjusted EBITDA in isolation or as a substitute for net income, cash flows from operations, or any other performance measures calculated in accordance with GAAP.  In addition, Adjusted EBITDA has inherent material limitations as a performance measure.  It does not include interest expense, but because we have borrowed money, interest expense is a necessary element of our costs.  In addition, Adjusted EBITDA does not include depreciation.  Since we have capital assets, depreciation expense is a necessary element of our costs.  Adjusted EBITDA does not include stock-based compensation, which is a necessary element of our costs since we issue stock awards to employees as an important incentive to maximize overall company performance and as a benefit of employment with the company.  Adjusted EBITDA does not include the fair value of warrants issued to non-employees, which is a necessary element of our costs since we have issued warrants to non-employees and as part of our financing strategy. Finally, Adjusted EBITDA does not include the fair value of common stock issued to consultants, which is a necessary element of our costs since we have issued shares of our common stock in lieu of cash payments to consultants we have retained. Because not all companies use identical calculations, our presentation of Adjusted EBITDA may not be comparable to other similarly titled measures of other companies.
