SECURITIES AND EXCHANGE COMMISSION WASHINGTON, D.C. 20549 ------------ FORM 8-K CURRENT REPORT PURSUANT TO SECTION 13 OR 15(d) OF THE SECURITIES EXCHANGE ACT OF 1934 ------------ Date of Report (Date of earliest event reported): August 3, 2000 PRIMUS TELECOMMUNICATIONS GROUP, INCORPORATED (Exact name of registrant as specified in its charter) DELAWARE 0-29092 54-1708481 (State or Other Jurisdiction of (Commission (IRS Employer Incorporation) File Number) Identification No.) 1700 OLD MEADOW ROAD, SUITE 300, MCLEAN, VIRGINIA 22102 (Address if principal executive offices) (Zip Code) Registrant's telephone number, including area code: (703) 902-2800 ITEMS 1-4. NOT APPLICABLE ITEM 5. On August 3, 2000 Primus Telecommunications Group, Incorporated announced its financial results for the quarter ended June 30, 2000.

SECOND QUARTER FINANCIAL RESULTS PRIMUS's net revenue in the second quarter of 2000 grew to a record $300 million, compared with $186 million for the second quarter of 1999, an increase of 62%. Record revenues were reported in the second quarter of 2000 for each of our major business regions, as well as sequential increases from the first quarter of 2000. On a year-over-year basis, net revenue in Europe increased 128% to $88 million; in North America net revenue increased 45% to $132 million; and in the Asia-Pacific region net revenue increased 42% to $80 million. These gains were made despite the continuing adverse impact of foreign currency exchange rates, which reduced revenue by approximately $9 million this quarter in comparison to the first quarter's average exchange rates. Data/Internet revenues, including voice-over-Internet Protocol (VoIP) revenues, for iPRIMUS.com totaled $27 million in the second quarter, which represents an increase of 349% year-over-year, and 32% sequentially from the first quarter of 2000. VoIP revenues of approximately $5 million for the second quarter were in line with the first quarter of 2000. The geographic mix of the revenue base in the second quarter was 44% from North America, 30% from Europe and 26% from Asia-Pacific. Part of the increase in revenue from the Asia-Pacific region was from local access in Australia, which resulted from unbundling of the local loop for consumers that we had anticipated for later in the year. PRIMUS began offering local service bundled with long distance services to respond to customer demand even though the current gross margins from local services is minimal. The mix of retail revenue for the second quarter of 2000 was 73.7% (31.2% business and 42.5% residential), as compared to 73.3% (31.2% business and 42.1%

residential) in the first quarter of 2000, showing relative growth of the retail sector. The carrier segment's share of total revenue declined in the second quarter to 26.3% of revenues from 26.7% in the prior quarter. Gross margin for the second quarter of 2000 increased 98%, reaching a record high of $85 million, compared with $43 million for the second quarter of 1999. As a percentage of net revenue, gross margin (which is computed after accounting for bad debt) for the second quarter of 2000 was a record 28.3%, up from 23.0% for the second quarter of 1999 and up sequentially from 28.0% for the first quarter of 2000. Selling, general, and administrative (SG&A) expenses for the second quarter of 2000 were $83 million, or 27.8% of net revenue, compared with $42 million, or 22.4% of net revenue, for the second quarter of 1999, and 27.5% for the first quarter of 2000. The SG&A increase reflects the impact of additional spending to grow the data and Internet business, to ramp up SME and Global Account activities, as well as the impact of the Company's acquisitions. PRIMUS has generated positive EBITDA for five consecutive quarters. EBITDA for the second quarter of 2000 was $1.5 million, as compared to $1.2 million in the second quarter of 1999. The Company's operating loss for the second quarter of 2000 was $(25.6) million, compared with $(11.3) million for the year-ago period. The net loss for the second quarter of 2000 was $(50.8) million, or $(1.27) per basic and diluted share, compared with a net loss of $(26.1) million, or $(0.92) per basic and diluted share, for the second quarter of 1999. The weighted average number of basic and diluted common shares outstanding this quarter was 40.1 million compared to 28.5 million for the second quarter of 1999. Capital expenditures for the second quarter of 2000 were over $60 million for continued network expansion, including continuing deployment of the ATM+IP network, fiber optic cable capacity, switches and equipment, data servers, and back office systems and software. PRIMUS's total investment in gross property, plant and equipment was $446 million at the end of June 2000. PRIMUS held cash and investments of $568 million at the end of June. We believe that this level of liquidity will allow us to fund our business plan through the end of next year, 2001. We continue to anticipate future capital spending at an average rate of $50 million per quarter through the end of 2001, even though the actual quarter-to-quarter spending amounts may vary, which should allow us to complete construction of our ATM+IP data network and data centers. If current capital market conditions continue to persist into the future, we would adjust this plan accordingly. We also should be able to derive future liquidity from additional vendor lease financing for our switches and network equipment, potential bank lines of credit against our working capital, and, if needed, from private equity investments above and beyond the additional $35 million committed by PRIMUS's existing strategic technology partners. * * *
