VOTE “FOR” THE RICE TRANSACTION

USING THE ENCLOSED WHITE PROXY CARD TODAY

October 12, 2017

Dear Fellow Shareholder:

In connection with EQT’s special meeting of shareholders on November 9, 2017, you are being asked to make an important decision regarding the future of your investment.

In June, we announced a compelling transaction to acquire Rice Energy Inc., which management and the Board of Directors believe is in the best interest of all EQT shareholders and will deliver significant value. Rice has an outstanding footprint that is largely contiguous to our existing acreage position and complements our pipeline infrastructure systems. Rice represents a pivotal strategic opportunity for EQT to have an unmatched asset position — and world-class inventory — in one of the most prolific natural gas basins in the United States. EQT has been operating in the Appalachian Basin for nearly 130 years, has drilled more than 2,500 horizontal wells, and understands the specialized techniques and nuances needed to operate in this region. As a combined entity with Rice, we expect to be well-positioned to capture significant operating efficiencies, improve overall well economics, and deliver stronger returns to our shareholders.

The EQT Board unanimously approved the Rice transaction and urges shareholders to use the enclosed WHITE proxy card to vote by telephone, Internet, or mail “FOR” all agenda items at the special meeting.

Significant benefits of the transaction include:

·                  Improved Upstream Returns, Driven by Consolidating Complementary Acreage Positions. In Greene and Washington counties of Pennsylvania, where EQT and Rice have congruent acreage positions, the Company expects to significantly increase the average lateral length drilled to improve upstream economics. Across the entire portfolio of upstream assets, the combination of two of the leading operators in the Basin provides the opportunity to apply best practices from both companies and enhance scale to lower the cost of procurement of goods and services.

·                  Attractive Financial Combination That Is Immediately Accretive. The transaction is expected to create one of the lowest-cost operators in the United States, with significant financial flexibility and liquidity and an anticipated investment-grade credit rating. EQT expects the transaction to be immediately accretive to cash flow per share in excess of 20% in 2018 and 30% in 2019, and also accretive to the intrinsic value of the owned assets on a per share basis.

·                  Significant Near-Term Synergies with Additional Long-Term Opportunities. EQT has identified anticipated expense synergies that would be driven by capital efficiencies from drilling longer well laterals and the elimination of duplicative G&A costs. The combined company should also be positioned to achieve additional synergies through improved well designs from sharing of drilling and completion best practices, optimization of marketing of natural gas, and the potential acceleration of midstream growth projects.

·                  Enhanced Midstream Growth Outlook. For our midstream infrastructure, expected benefits include the more efficient build-out of gathering assets to service the upstream footprint of the combined company. Additionally, the larger combined upstream asset base should support incremental midstream projects and drive future midstream growth.

EQT’s Board conducted a thorough review of all alternatives prior to pursuing the merger with Rice and evaluated numerous analyses of both the transaction as well as standalone options. After completing due diligence and financial analysis, and considering the scarcity value of strategic opportunities capable of delivering significant shareholder value through synergies, EQT’s Board and management team determined that the Rice transaction creates more value than the other alternatives. In fact, pursuing the merger should enhance EQT’s ability to unlock value by improving the competitive positioning of each of EQT’s key businesses and increasing optionality.

VOTE TO SUPPORT ENHANCING SHAREHOLDER VALUE

AND STRENGTHENING EQT

This is an exciting time at EQT. The value creation opportunities for EQT from the Rice acquisition are meaningful and unique. We believe this transaction enhances our ability to unlock the substantial value embedded within our legacy EQT assets as well as within the acquired Rice assets, which is a top priority. To that end, immediately upon the closing of the Rice transaction, EQT will establish a committee of the board of directors to evaluate options for addressing the sum-of-the-parts discount in our stock.

Your vote is extremely important, regardless of how many or how few shares you own. Whether or not you expect to attend the EQT special meeting in person, we encourage you to submit a proxy to vote your shares as promptly as possible. You may vote by Internet, telephone, or by signing and dating the enclosed WHITE proxy card and mailing it in the postage-paid envelope provided.

On behalf of your Board, we thank you for your continued support. We remain confident in the significant value this combination will deliver and look forward to the future of a stronger EQT.

Sincerely,

If you have any questions about how to vote your shares, or need additional assistance, please contact our proxy solicitor:
