FOURTH QUARTER AND YEAR END 2012 RESULTS

Burlington, MA – January 30, 2013 — MicroFinancial Incorporated (Nasdaq:MFI), a financial intermediary specializing in vendor-based leasing and finance programs for microticket transactions, today announced financial results for the fourth quarter and the year ended December 31, 2012.

2012 Full Year Highlights Include:

Fourth Quarter 2012 Results:

Net income for the fourth quarter of 2012 remained flat at $2.4 million or $0.16 per diluted share based upon 14,731,946 shares for the fourth quarter of 2012 and 14,547,820 shares for the same period last year.

Revenue in the fourth quarter of 2012 increased by 8.9% to $15.3 million compared to $14.1 million in the fourth quarter of 2011 due primarily to increases in leasing revenues associated with new lease originations and rental revenue. Revenue from leases was $10.3 million, an increase of $0.8 million from the same period last year and rental income was $2.6 million, an increase of $0.3 million from the quarter ended December 31, 2011. Other revenue components contributed $2.5 million for the current quarter, an increase of $0.2 million from the same period last year.

Total operating expenses for the current quarter increased 13.2% to $11.6 million from $10.3 million in the fourth quarter of 2011. Operating expenses included an increase of $0.6 million in selling, general and administrative expenses, primarily related to additional personnel expenses and an increase in bank service charges associated with the larger number of accounts in the portfolio. The provision for credit losses increased by $0.5 million as compared to the same period last year bringing the quarterly provision to $5.2 million. This increase was due in part to growth in the lease portfolio over the prior year. Fourth quarter net charge-offs decreased to $4.5 million from $4.7 million in the comparable period of 2011. Depreciation and amortization expense increased $0.3 million to $1.2 million primarily due to the increase in the number of lease contracts maturing and converting to rentals. Interest expense remained relatively flat at $0.6 million for the quarter due to lower interest costs offset by greater amounts outstanding on the Company’s revolving line of credit.

Cash received from customers in the fourth quarter increased 20.0% to $32.3 million compared to $26.9 million during the same period in 2011. New originations increased 6.2% to $22.8 million during the fourth quarter of 2012, compared to $21.5 million in the fourth quarter 2011.

Included in these operating expenses were increases of $1.6 million in selling, general and administrative expenses which increased to $17.5 million primarily related to increases in personnel related costs, postage expenses and marketing costs.

Recoveries increased slightly to $5.2 million during 2012 as compared to $5.0 million in 2011. Depreciation and amortization expense increased $1.1 million to $4.4 million due primarily to an increase in the number of lease contracts reaching maturity and converting to rentals. Interest expense remained relatively flat at approximately $2.6 million for the year as compared to 2011 due to lower interest costs on the revolving line of credit which were offset by higher outstanding debt balances.

Headcount at December 31, 2012 was 152, which increased from 135 at the end of 2011. Cash received from customers was $121.8 million during 2012 as compared to $106.3 million for the prior year.

Richard Latour, President and Chief Executive Officer said, “We are very pleased with our operating results for 2012. We successfully executed on several strategic initiatives designed to expand our market footprint and increase our lease originations. The investment in sales and marketing initiatives resulted in an 18% growth in dollars of applications and a 17% increase in year over year originations. In addition, we increased net income and cash receipts to $9.4 million and $121.8 million, respectively. We were able to reward our shareholders with an increase in the dividend payout rate to $0.24 per share for 2012 as compared to $0.21 in 2011. Lastly, we were able to increase our revolving line of credit facility from $100 million to $150 million with more favorable terms and extended the maturity date to December of 2016.”
