This news release contains "forward-looking information and statements" within the meaning of applicable securities laws. For important information with respect to such forward-looking information and statements and the further assumptions and risks to which they are subject, see the "Cautionary Statement Regarding Forward-Looking Information and Statements" later in this news release.

CALGARY, Nov. 23, 2018 - Precision Drilling Corp. (“Precision” or “the Company”) (TSX:PD; NYSE:PDS) today confirms its continued support for the strategic share exchange merger (the “Precision Transaction”) with Trinidad Drilling Ltd. (“Trinidad”) (TSX:TDG) on the basis of 0.445 of a Precision common share (a “Precision Share”) for each Trinidad common share (a “Trinidad Share”).

The Company strongly encourages Trinidad shareholders not to tender their Trinidad Shares to Ensign Energy Services Inc’s. (“Ensign”) (TSX:ESI) opportunistic all cash take-over offer for all of the Trinidad Shares (the “Ensign Offer”), at near an all-time low value for Trinidad. Further, the Trinidad Board of Directors (“Trinidad Board”) has unanimously recommended that Trinidad shareholders REJECT the inadequate Ensign Offer.

Trinidad shareholders do not need to take any action if they wish to NOT tender their Trinidad Shares. Trinidad shareholders that have questions or require assistance with withdrawing their Trinidad Shares which were tendered in error should contact Trinidad's Information Agent, D.F. King Canada, toll free at 1.866.521.4427 (212.771.1133 by collect call) or by email at inquiries@dfking.com. Trinidad and Precision shareholders will have the opportunity to vote for the Precision Transaction on December 11, 2018. If you are a beneficial shareholder that has not received your materials for the securityholder meetings to approve the Precision Transaction you are encouraged to contact your broker directly for information on how to vote your shares.

The Precision Share price is positioned to benefit in the near-term from potential macro developments and Trinidad shareholders can participate in the potential upside by not accepting the Ensign Offer and voting in favor of the Precision Transaction. Strengthening natural gas prices, a potentially supportive OPEC meeting on December 6^th, new Permian pipelines set to open in 2019 and 2020, and potential solutions to solve the challenged Canadian WCS spread are all expected to be near-term catalysts for Precision.

The acceleration by Ensign of the inadequate Ensign Offer, at a historically low value for Trinidad, seeks to deprive Trinidad shareholders the opportunity to properly consider the Precision Transaction and to deny Trinidad shareholders the value of time by forcing them to make a rash decision without the potential benefit of exposure to near-term positive macro events. The acceleration of the inadequate Ensign Offer benefits Ensign at the expense of Trinidad shareholders. Ensign has the ability to extend the timing of its offer to allow the Trinidad shareholders more time to consider the merits of the Precision Transaction.

Precision’s President and CEO Kevin Neveu stated: “Precision’s operations continue to demonstrate strength and we see a number of positive catalysts as we survey the energy market outlook. We expect to generate significant free cash flow from our industry-leading rig fleet, supported by several billion dollars of capital investment this decade.”

“Current oilfield sector valuations are near decade-low valuations, and this does not appear to be the time to sell for cash. In fact, the Precision Board and management have been buying Precision Shares over the past month. By voting to combine with Precision, the Trinidad shareholders are well positioned to benefit from the strength of the combined company and the $52 million in annual synergies we expect to generate.”

“We remain committed to our offer and have had positive conversations about the combination’s value creation potential with both Trinidad and Precision shareholders. The superior Precision Transaction offers Trinidad shareholders a clear path to realize significant value and to share in the combined company upside. Trinidad’s excellent assets, strong customer relationships and highly-skilled personnel align well with Precision’s High Performance, High Value operations. Trinidad investors are not receiving appropriate value by selling to Ensign and exiting their investment now as they will be surrendering their unappreciated value to Ensign at a historically low price,” concluded Mr. Neveu.

Precision comments on misinformation press released by Ensign on November 16, 2018:

Ensign’s assertion: “Full and Fair Value for Trinidad Shareholders.”

• Precision believes over time the value realized by Trinidad shareholders by owning 29% of the combined company will be greater than the cash value of $1.68 available now.
• The inadequate Ensign Offer solidifies Trinidad's value at a low point in the industry and takes all the benefit of efficiency gains and future industry improvement for Ensign shareholders, at the expense of Trinidad shareholders.

Ensign’s assertion: “Precision’s depressed share price means that Trinidad Shareholders will not receive full value for their Common Shares.”

• The Precision Share price has fluctuated materially through 2018 and significant upside remains. Based on the exchange ratio of 0.445 of a Precision Share for each Trinidad Share, the value to Trinidad shareholders at Precision’s 2018 high was $2.37 per share, 41% higher than the Ensign offer. This demonstrates the upside potential beyond the current implied exchange price.

Ensign’s assertion: “Trinidad Shareholders will be exposed to the risks of increased financial leverage.”

• Precision’s credit ratings are generally stronger than Trinidad’s credit ratings and each credit agency following Precision viewed the proposed combination with Trinidad positively.
• The Precision Transaction is modestly deleveraging for Precision with year-end 2019 Net Debt/Adjusted EBITDA estimated to be below 3.0x, based on Precision-provided guidance supported by industry research analysts.
• Precision’s credit facility is undrawn with approximately $867 million of liquidity in the combined company as at September 30, 2018.
• Precision’s first note maturity is due in December 2021, over three years from today.
• As demonstrated through previously provided guidance, Precision is expected to generate strong free cash flow and to continue to reduce the combined company’s debt levels.

Ensign’s assertion: “The Inferior Precision Offer is not in the best interest of Trinidad Shareholders.”

• The Trinidad Board has determined the Precision Transaction is in the best interest of Trinidad shareholders.
• The Precision Transaction provides Trinidad shareholders with the opportunity to be part of a combined company with significant upside potential and immediately improved public markets scale and liquidity.

Ensign’s assertion: “The Inferior Precision Offer benefits current Precision shareholders at the expense of Trinidad Shareholders.”

• The Precision Transaction allows Trinidad and Precision shareholders to share in the synergies of the combined company, whereas the inadequate Ensign Offer allows only Ensign shareholders to realize the value of the synergies.
• The Precision Transaction was negotiated by both companies and has the unanimous support of the Trinidad Board.

Precision comments on misinformation press released by Ensign on November 22, 2018:

Ensign’s assertion: “Realization by Precision of synergies from their proposed acquisition of Trinidad is equally uncertain.”

• Precision has completed a detailed review of the combined companies’ potential fixed cost synergies and operational scale-based efficiencies and is confident that its estimate of $52 million in annualized synergies is attainable.
