Toronto, ON, May 10, 2007 – Student Transportation of America Ltd. (“STA” or the “Company”) (TSX: STB.UN) today reported the financial results for its third quarter of fiscal year 2007, ended March 31, 2007. All financial results are reported in U.S. dollars, except as otherwise noted.

For the third quarter, revenue totalled $49.2 million, up from $39.9 million for the same period last year and EBITDA* rose to $10.4 million from $9.0 million in the same period in fiscal 2006.

STA’s reported net loss for the three month period ended March 31, 2007 of $0.2 million or $0.01 per common share which includes $2.4 million of interest paid during the quarter to Unitholders on the subordinated notes portion of the IPS units.

For the quarter, the Company generated cash available for distributions* of C $11.1 million and paid out distributions of C $5.8 million. Net cash provided by operations amounted to $7.7 million for the three month period ended March 31, 2007. As stated previously, due to the seasonality of the business and schools not being in operation during the majority of the first quarter, the Company views distributable cash on an annualized basis.

“This was a good quarter for us resulting in double-digit growth of revenue and EBITDA compared to the same quarter last year as a result of our growth strategy of acquisitions, bids and conversions,” said Denis J. Gallagher, Chairman and Chief Executive Officer. “During the quarter, we strengthened our balance sheet by paying down debt with the net proceeds of a completed C $20 million offering of our common shares.”

The Company said revenue for the quarter was slightly less than anticipated by $1.1 million, and estimates a corresponding effect on EBITDA of approximately 50%, due to schools in several of STA’s regions experiencing closures during the winter months due to poor weather conditions. An unexpected teachers’ strike in Pennsylvania also resulted in two weeks of school closures in that region. The Company stated higher costs associated with its Riverside California operation have continued and expect them to continue through the balance of the school year.

“Historically we get to recover most of the revenue caused by factors such as weather and teacher strikes, although it is not certain we will recoup the full amount. We are confident that the cost issues at Riverside will be resolved and continue to believe that this contract will contribute to the Company’s long term growth,” said Gallagher. “We are also pleased that our recently renewed insurance program came in with a lower fixed cost due to our outstanding safety performance. We also have agreed to extend our vehicle leasing program through fiscal year 2008 at approximately the same 6 per cent fixed rates for our replacement capital expenditures”

For the nine months ended March 31, 2007, revenue totalled $122.3 million, up from $95.1 million for the same nine month period last year and EBITDA* rose to $19.7 million from $17.7 million in the same nine month period in fiscal 2006. STA’s reported net loss for the nine month period ended March 31, 2007 was $8.8 million or $0.42 per common share which includes $7.2 million of interest paid to Unitholders on the subordinated notes portion of the IPS units.

* Non-GAAP Measures

EBITDA is a non-GAAP financial measure, but management believes it is useful in measuring STA’s performance. Readers are cautioned that this measure should not be construed as an alternative to net income or loss or other comparable measures determined in accordance with GAAP as an indicator of the Company’s performance or as a measure of its liquidity and cash flow. The Company’s method of calculating non-GAAP measures may differ from the methods used by other issuers and accordingly, the Company’s non-GAAP measures may not be comparable to similarly titled measures used by other issuers.

Cash available for distributions is a non-GAAP measure, and is not intended to be representative of cash flow or results of operations determined in accordance with GAAP. Investors are cautioned that cash available for distribution, as calculated by the Company, is unlikely to be comparable to similar measures used by other issuers.
