BASi Reports Third Quarter Net Income of $.03 Per Share

WEST LAFAYETTE, IN, August 14, 2014 — Bioanalytical Systems, Inc. (NASDAQ:BASI) today announced financial results for the third quarter and first nine months of fiscal 2014.

"BASi's financial performance for the first nine months of fiscal 2014 showed significant improvement over last year, as revenue increased 9.7% and net income before the change in fair value of the warrant liability increased 88%. EBITDA for this fiscal year's first nine months was a solid 11.5% of revenue versus 13.5% of revenue for the same period in fiscal 2013, reflecting the planned increase in our investments in selling and R&D as well as a change in the mix of business. Also, cash flow from operations for the first nine months of fiscal 2014 remained strong at $1,215,000 versus $1,418,000 for the same period of fiscal 2013, while we reduced our line of credit borrowings by $1,400,000 so far this year in addition to the $1,100,000 reduction in line of credit borrowings we achieved for the first nine months of fiscal 2013," said President & Chief Executive Officer Jacqueline Lemke.

"These results clearly demonstrate the benefits of our intense focus on three key areas: boosting operating efficiency, driving top line growth, and generating free cash flow. We will continue to take decisive actions and make targeted investments to improve our financial performance. Expanding our marketing efforts by building on BASi's inherent strengths and reputation for excellence, combined with our unrelenting effort to accelerate best practices and drive continuous improvement, has positioned BASi for higher profitable growth in the future."

Highlights of the third quarter included:

Ms. Lemke concluded, "While we remain focused on reducing our costs through productivity and place continued emphasis on generating free cash flow, we are also dedicated to the strategies that drive our top-line growth. Our commitment to our customers, shareholders, and employees has never been stronger. We are intensifying our efforts to improve our processes, embrace change, and wisely employ our stronger liquidity position. We will continue to take actions to make BASi a stronger company. We see many opportunities for growth, and we are pursuing them with confidence."

Non-GAAP to GAAP Reconciliation

This press release contains financial measures that are not calculated in accordance with generally accepted accounting principles in the United States (GAAP). The non-GAAP financial measures are net income and net income per basic and diluted share, excluding the income or expense of the change in the warrant liability, and EBITDA, in each case for the third quarter and for the first three quarters of fiscal 2014 and 2013. EBITDA refers to financial performance measures that exclude certain income statement line items, such as interest, taxes, depreciation, and amortization. EBITDA may also exclude certain non-cash or one-time expenses, such as stock-based compensation and the income or expense from the change in the warrant liability.

The non-GAAP financial information should be considered supplemental to, and not as a substitute for, or superior to, financial measures calculated in accordance with GAAP. Management, however, believes that these non-GAAP financial measures, when used in conjunction with the results presented in accordance with GAAP, may provide a more complete understanding of the Company's results and may facilitate a fuller analysis of the Company's results, particularly in evaluating performance from one period to another.

Management has chosen to provide this supplemental information to investors, analysts, and other interested parties to enable them to perform additional analyses of results and to illustrate the results giving effect to the non-GAAP adjustments shown in the reconciliation. Management strongly encourages investors to review the Company's consolidated financial statements and publicly filed reports in their entirety and cautions investors that the non-GAAP measures used by the Company may differ from similar measures used by other companies, even when similar terms are used to identify such measures.
